Abstract

ARTICLE FORMING SYSTEM

Abstract of Disclosure An article forming system for forming at least one sheet or material into an article, such as a decorative flower pot cover for example, and a novel article formed utilizing such a system. The article forming system in-cludes a male die, a female die and a platform having a support surface and an opening extending through the support surface. The female die is disposed generally within the opening in the platform with the upper end of the female die being disposed near the support surface. The article forming system includes means for slidingly holding portions of the sheet of material generally against portions of the support surface while permitting such held portions to slide on the support surface during the forming of the arti-cle for cooperating in forming a decorative border on the decorative flower pot cover type of article which flares generally away from the flower pot object when the decora-tive flower pot cover article is applied to the flower pot.
The article formed in accordance with the present invention includes overlapping folds formed by overlapping portions of the sheet of material to bring portions of the sheet of material into bondable contact, the overlapping folds pro-viding the mechanical strength necessary for the formed sheet of material to hold a predetermined shape thereby permitting the utilization of thinner sheets of material to form articles.

ARTICLE FORMING SYSTEM

Field of ~he Invention The present invention relates generally to an article forming system and an article formed using such article forming system and, more particularly, but not by way of limitation, to an article like a decorative 1~ flower pot cover and an article forming system for forming such a decorative flower pot cover article.

_ckround o~ the Invention In recent years, decorative covers for flower pots typically have been provided utilizing florist foil.
A florist took a sheet of foil and placed the flower pot ;on the foil. The florist then hand-wrapped the foil about the flower pot outer periphery and formed the decorative cover. The cover could be formed in this manner because the foil sheet of material was shape-sustaining.
With this technique utili~ing florist foil, each cover was individually formed about the flower pot.
Thus, the shape or overall appearance of each cover was dif~erent and dependent upon the level of skill, and the ~5 artistic and personal inclination of the florist.
~;~Typically, there are certain times during a ~i ~year, typicaIly holidays, when the florist's sales of potted plants substantially increase. The florist normally would not employ sufficient trained staff to ~0 accommodate the substantial increases in sales during such periods. It thus becomes necessary to utilize untrained labor to form the flower pot covers utilizing the sheets of florist foil particularly during these peak periods. In addition to these instances, there are other B 35 circumstances depending on the business of the user where :. ` :
., `' :`
,,, ..
., ~L2695S8 -la-flower pot covers are desi~able and where trained help simply is not available or desirable for various reasons.
For many years, there has existed a need for a suitable preformed flower pot cover for the reasons mention~d before.
One significank problem which has persisted is to provide a flower pot cover which is preformed, yet which retains the festive, airy, artistic qualities achieved by experienced florists' hand-forming florist foil. In addition, the cost of florist foil has increased in recent years and there has existed a desire to find a suitable, less expensive substitute material.
One attempt to utiliæe a substitute material as a flower pot cover is represented in U.S. Patent No.
4,300,312, entitled "Flower Pot Covering" and owned by the present applicant. This patent disclosed a cradle which could be placed about the base of a flower pot for holding a thin plastic film about the exterior of the flower pot in the form of a flower pot cover. This patent did disclose a way of using a thin plastic film as a flower pot cover, thereby providing a flower pot cover which was festive and airy. However, the cover was not preformed and a separate device (the cradle) was required to hold the non-shape-sustaining plastic film about the flower pot.
U.S. Patent No. 4,216,620 entitled "Flower Pot Cover with ~ace Edging" and assi~ned to the present applicant disclosed another prior approach ko providing a ~lowering covering material. In this patent, a flexible, non-shape-sus~aining plastis film was laminated to a shape sustaining metallic foil to provide a shape-sustaining material incorpora~ing the non-shape-- sustaining plastic film for use as a flower pot wrapping or covering material.
U.S. Patent No. 4,297,811, entitled "Lamina~ed .; .. :

flower pot cover type of article since one extremely ad-vantageous use of the system of the present invention is to form such decorative flower pot cover types of articles.
However, a decorative flower pot cover represents only one article which can be ~ormed into a prede~ermined shape in accordance with the present invention and the present invention specifically contemplates various and numerous o-ther types of articles such as vases, hats, saucers, easter baskets, containers for use in microwave ovens, rose 10 stem boxes, egg cartons, potting trays, pans, trays, bowls, basket liners, candy trays, drinking cups, candy cups, ~lower pots, planter trays for growing plants, disposable bowls and dishes, corsage boxes and containers, food ser-vice trays (such as those used for bakery goods, french 15 fries, ground beef, liver and other raw meats in supermar-kets, for example), boxes for hamburgers or pies and the - ~ like, and various other articles. The term ''article'' as used herein is intended to encompass all of the specific -~ articles just mentioned and the term "article'' also is intended to be broad enough to encompass any other article having a predetermined shape where the article to function must be capable of substantially maintaining such prede-termined shape.

The present invention particularly contemplates 25 articles being formed into a predetermined shape from a sheet of material having a relatively small thickness and being of the type commonly referred to in the art as a "film". More particularly, the sheet of material contem-; platèd by the present invention is a processed, man-made 30 organic polymer selected from the group consisting oE
polypropylene, polyvinyl chloride9 or combinations thereof.
The sheet of material contemplated by the present invention is relatively thin having a thickness less t~an about 1~5 :.,~

6mills and the sheet of material is.very f-~e~e and flimsy so that the sheet of material will not normally maintain or hold a predetermined fcrmed shape under normal, usual con-ditions (non-shape sustaining). In some instances and for various reasons, it may be desirable to utilize more than one sheet of material and, in these instances, the sheets of material are layered, placed one on the other, when the sheets of material are formed into the predetermined shape to form the desired article; however, even in these instances, the combined thickness of the sheets of material still is less than about 3Ømills. The present invention provides a means for iorming a sheet o-E material of the type just described into a predetermined shape so the ~ormed sheet of material substantially retains or maintains the formed shape thereby providing a means for making articles from such sheets of material in a more economical manner.

: The decorative flower pot cover article 14 prefer-ably, although not exclusively, is formed from a generally square-shaped sheet of material 12 having four corners.
As shown in Figures 3A and 3B, the decorative flower pot cover article 14 formed from the generally square-shaped sheet of material 12 utilizing the system I0 of the present invention includes a base 26 having an opened upper end 28, a closed lower end 30, an object opening 32 extending 10 through the upper end 28 and a decorative border 34 which extends angularly upwardly and outwardly from the upper end 28 of the base 26. The decorative border 34 lncludes four accentuated and sculptured flared petal.-like portions 36, each flared petal-like portion 36 terminating with a : 15 pointed end 38 which is formed by one of the four corners of the square-shaped sheet of material 12. Each flared petal portion 36 extends a distance angularly upwardly and : outwardly from the upper end 28 of the base 26 termi.nating:
: ~ with the pointed end 38. The flared petaI-like portions : 20 36 are spaced apart circumferentially about the decorative :~ border 34 with the flared petal-like portions 36 being spaced at about ninety degree intervals, and a flare connecting portion 40 is disposed between each pair of adjacent flared portions 36, the flare connection portions 25 4~ also each extending a distance angularly upwardly and : outwardly from the~upper end 28 of the base:26 which is less than the distances which the pointed ends 38 of the : flared portions 36 extend from the upper end 28 of the base 26.

In this position with the decorative Elower pot cover 14 operatively connected to the :10wer pot 16, the decora-tive border 34 of the decorative flower pot cover 14 ex-15 tends a distance angularly upwardly and outwardly from the ~ upper end 18 of the flower pot 16 and the decorative flower .~ pot cover 14 extends generally circumEerentially about the upper end 18 portion of the flower pot 16.

:::: As shown in Figures 3A and 3C, the base 26 of the ; 20 decorative flower pot cover 14 formed utili~ing the system 10 of the present invention includes a plurality of over-lapping folds 42 (only some o:E the overlapping Eolds 42 being designated by a reference numeral in the drawings).
A substantial portion of the overlapping folds 42 extend :25 at angles to a vertical di~rection and at angles to a hori-zontal direction, the various angles being arbitrary and varying from one overlapping:fold 42 to another overlapping -fold 42. Further, the base 26 includes a plurality of overlapping -folds 42 with the various overlapping folds 42~being positioned at various positions about the entire outer peripheral surface of the base 26 and at various positions between the upper and the lower ends 28 and 30 oE the base 26. The overlapping folds 42 provide an over-,.

In this manner, the base 26 o~ -the decora-tive flower pot cover 14 has sufficient mechanical strength to stand upright about the ~lower pot 16 without the necessity of mechanically connecting -the 10 base 26 to the flower pot 16, other than the connection nor-ma].ly provided when the lower end 20 o~ the ~lower pot 16 engages the lower end 3~ of the decorative flower pot cover 14 when the decorative flower pot cover 14 is operatively connected to the flower pot 16. Each overlapping fold 42 15 extends an arbitrary distance and most of the overlapping folds 42 extend at arbitrary angles over the base ~6 which enhances the mechanical strength of the base 26 as compared to the mechanical strength which might be imparted to the base 26 by overlapping ~olds extending only in vertical or 20 horizontal directions. Significantly, the overlapping fol~s 42 permit relatively thin sheets (films) o~ material to be utilized to form the decorative flower pot cover 149 in a manner and for reasons to be discussed -further below.

As shown in Figure 3C, the sheet o-~ mate~ial 12 ~5 has an upper surface 41 and a lower surface 42 and, in accordance with the present invention, either the upper surface 41 or the lower surface 42 or both of the sheet of material 12 is adapted to be bondable so that, when por-tions of the bondable surface are brought into bondable 30 contact, such portions are bondably connected. The over-lapping folds 42 are -formed by overlapping portions o-f the bondable surface and bringing sucb overlappi~g portions in-to bondable engagement or contact. In this manner, the `~, .. ~ ".

overlapping folds 42 are permanently ~ixed in the article.

When an overlapping fold 42 is formed with a por-tion of the sheet of material 12 during the forming of the ; decorative flower pot cover 14, portions of the upper surface 41 are overlapped and brought into bondable con-tact or engagement and, with respect to the same overlapping fold 42, portions of the lower surface 42 also are over-lapped and brought into bondable contact or engagement. As mentioned before, at least one of the upper and the lower 10 surfaces 41 and 43 is prepared to be bondable to form a bondable sur~ace which is adapted to be bonded to portions of a similar bondable surface when bondably contacted with a similar bondable surface portion. Thus, in those in-stances where only the lower surface 43 is prepared to form 15 a bondable lower surface 43, the overlapping portions of the bondable lower surface 43 are brought into bondable contact during the forming of the decorative flower pot ~ cover 14 and such overlapping portions are bonded to form ; the overlapping folds 42, and, in this instance, the cor-20 responding overlapping portions of the upper surface 41 are not bonded. In those instances where only the upper surface 41 is prepared to form a bondable upper surface 41, the overlapping portions of the bondable upper sur-face 41 are brought into bondable contact during the 25 forming of the decorative flower pot cover 14 and such overlapping portions are bonded to form the overlapping folds 42 and, in this instance, the corresponding over-lapping portions of the lower surface 42 are not bonded.
In those instances where both the upper and the lower sur-30 -~aces ~1 and 43 are prepared to form bondab]e upper and ~` lower surfaces 41 and 43, -the overlapping portions of the upper and the lower surfaces 41 and 43 -Forming each over-lapping fold 42 are brought into bondable contact during . .

the forming of the decorative flower pot cover 14 and such overlapping portions of the upper and the lower surfaces 41 and ~3 are bonded to form the overlapping folds 42.

It has been found to be necessary only to prepare one of the upper and the lower surfaces 41 or 43 to form a bondable surface so the decorative flower pot 14 is forma-ble -From the film sheet of material 12 having sufficient mechanical strength to retain its formed shape in accor-dance with the present invention. However, l-t shou:ld be 10 noted that preparing both the upper and the lower surEaces 41 and 43 l:o forrn bondable surfaces provides a~ditional mechanical strength which may be desired in some applica-tions and particularly in those applicatons where the additional mechanical strength is needed to enable the 15 formed article to maintain or retain its formed shape, such additional strength being needed either because of the particular shape of the article or the particular thickness or characteristics of the particular Eilm forming the sheet of material 12.

Various techniques are utilized to prepare the sheet of material 12 with at least one bondable surface in accordance with the present invention.

One technique for preparing the bondable surfaces ~` is to utilize polyvinyl chloride film to form -the sheet of 25 material 12 which is heat sealable. When utilizing a processed organic polymer heat sealable film, the upper and the lower surfaces 41 and 43 of the sheet of material 12 are bondable surfaces and the sheet of material 12 must be ~ heated during the forming of the article or, more particu-;~ 30 larly, the forming of overlapping folds 42. Thus~ in this instance, the term "bondable contact" or "bondable engage-'"

ment" means contacting engagement and the application of the required amount of heat to effect heat sealable bonding of the contacting surfaces.

It should be noted that a light activated adhesive also i5 suitable for use in preparing the bondable surface in accordance with the present invention. In this instance 9 heating elements would not be necessary, however, means for lighting the areas to be bonded would be necessary which might be et`Eected by substituting ligh-t sources for the 10 heating elements described herein and constructing the male and Eemale dies of a light transparent material. In this ; instance, ~he term "bondable contact" or "bondable engage-ment" means contacting engagement and -the applications of sufficient light to effect the bond.

One other technique for preparing the bondable sur-faces is to utilize a non-heat sealable film to form the ~ sheet of material }2 and to apply a heat sealable coating - to either the upper surface 41 or the lower surface 43 or both. Heat sealable adhes:ives are commercially available.
~0 The term "bondable contact" or "bondable engagement" as used in this instance means contacting engagement and the application o~ the required amount o-f heat to e-ffect heat sealable bonding of the contacting surfaces. The heat sealable coating also can be a heat sealable lacquer, a 25 pressure sensitive adhesive which also requires heat to ef-~ect the bond, or a hot melt adhesive.

One other technique for preparing the bondable sur-faces is to utilize a non-heat sealable film to form the sheet of material 12 and to apply a contact adhesive 30 coating either the upper surface 41 or the lower surface 43 or both. Contact adhesives are commercially available.

i58 The term "bondable contact" or "bondable engagement" in this instance means contacting engagement suf~icient to effect the adhesive bond between the contacted surfaces.

For aesthetic purposes, it is preferable that the decorative border 34 and particularly the flared petal-like portions 36 remain substantially smooth, substantially free of the overlapping folds. Also, it is desirable that the flare connecting portions 40 also remain substantially smooth, substantially free of the overlapping folds. The 10 cover forming system 10 is constructed and adapted sub-stantially to accomplish these desired characteristics of the decorative ~lower pot cover 14 in a manner which will be described in greater detail below.

As shown in ~igure 1, the system 10 includes a male 15 die 44 having an upper end 46 and a lower end 48. A male die surface 50 is -formed on a portion of the outer periphe-ral surface of the male die 44 and the male die surface 50 extends a distance generally from the lower end 4~ toward the upper end 46 of the male die 44. A portion of the male 20 die surface 50 extending from the lower end 48 a dis-tance toward the upper end 46 o-f the male die 44 forms a base portion 52 of the male die surface 50, and the base portion 52 of the male die sur-face 50 has an outer peripheral sur-face which is shaped about the same as the outer peripheral 25 surface 22 of the flower po-t object 16, the dimensions of the base portion 52 being slightly larger than the compara-ble dimensions of the outer peripheral surface 22 of the flower pot 16, so the decorative flower pot cover 16 will fit generally about the outer peripheral surface 22 of the ~; 30 flower pot 16 when the decorative flower pot cover 1~ is operatively connec-ted to the flower pot 16. The base portion 52 has an upper end 54 and a lower end 56, the .

Each inclined support sur-ace 126 is generally triangularly shaped with the base of each triangularly shaped inclined support sur~ace 126 being disposed near the opening in the female die 94 and with each triangularly 30 shaped inclined support surface 1~6 extending upwardly and terminating with the triangle ape~ outermost end. The in-clined support surfaces 126 are spaced apart at about ninety .

: , ~

355~3 degree intervals circumferentially about the opening i~ the Lemale die 94, and the inclined support surfaces 126 are arranged about the female die 94 so the edges o~ such sup-port suriaces 126 cooperate to form a substantially square ; S shape in a plan view as shown in Figure 2 with the outer~
~ most ends of -the inclined support surfaces 126 forming -the : corners o~ thi.s square shape.

Each inclined support surface 126 is connected to the plat~orm 120 by a pair of sides 128 and 130, as shown 10 in Figure ~ with respect to one o~ the inclined support surfaces 126. Each inclined support surface 126 cooperates with the sides 128 and 130 connected thereto to encompass ; an enclosed space. A plurality o~ hold openings 134 ar~
-formed through each inclined support surface 126 ~only two 15 of the hold openings 134 being designated by re~erence numerals in Figures 1 and 2) and the hold openings 134 in ` each inclined support surface 126 are in communica-tion with the space enclosed by that inclined support surface 122 ~ cooperatlng with the sides 128 and 130.

: 20 A vacuum source 136 is connected to each o~ the spaces enclosed by the inclined support surfaces 126 and : cooperating sides 128 and 130 and a control valve 138 is interposed between the enclosed spaces and the vacuum source 136, the vacuum source 136 being in communication ~:~ 25 with the hold openings 134 in the inclined support surfaces :: .
:~ 126 in the opened position of the control valve 138. In one (opened) position of the control valve 138, communica-: tion is established between the hold openings 134 and the :~ vacuum source 136 and, in one other (closed) position of : 30 the control valve 138, communication is interrupted between ,, .
~ the hold openings 134 and the vacuum source 136.

~2~ 5~3 Adjacent pairs of inclined support sur~aces 126 are spaced a distance apart thereby -~orming a substantially flat, horizontally disposed flat portion 140 o~ the support sur-face 122 which is disposed generally between each pair of adjacent inclined support sur~aces 126. Each flat por-tion 140 extends a distance radially outwardly from theopening in the female die 94. The flat portions 140 co-operate with the inclined support surfaces 126 to form the support sur~ace 122.

A plurality of spaced apart ribs 142 are connected 10 to the support surface 122 with some of the ribs 1~2 being disposed in each fla-t portion 140. Each rib 142 has an arc-shaped cross section with a rounded uppermost end por-tion and each rib 142 extending a distance radially out-wardly from the opening in the female die 94, the ribs 142 15 in each flat portion 140 being spaced distances apart.

In operation, the sheet of material 12 is placed on the support surface 122 of the platorm 120 with a central portion o~ the sheet o~ material 12 being disposed generally over the opening in the female die 94. ~s mentioned be-20 fore, the sheet of materia] 12 preferably is square-shaped and, in this instance, each corner of the square-shaped sheet of material 12 is placed near the apex of one of the inclined support surfaces 122, each porticn of the sheet of material 12 disposed adjacent the corner being disposed 25 generally over the inclined support surface 126. In this position, the sheet of material 12 is disposed on the sup-: port surface 122 generally between the male die 44 and the : female die 94.

Initially, the hydraulic cylinder 66 supports the : 30 male die 4~ in the storage position disposed a distance ., .

above and generally over the female die 94. The controlvalve 84 is positioned to connect the openings 76 in the male die 44 to the vacuum source 80 and the control valve 138 is positioned to connect the hold openings 13~ in the inclined support sur~aces 126 to the vacuum source 136.
The heating elements 96 in the male die 44 and the heating elements 118 in the :eemale die 94 each are connected to the electrical power supply 92 so the heating elements 96 co-operate to heat the male die sur~ace 50 to the prede-ter-10 mi.ned temperature level and -the heating elements 118 in -the ~emale die 9~ cooperate to heat the female die surface 100 -to the predetermined temperature level.

Since the hold openings 134 in the inclined support ~; surfaces 122 are in communication with the vacuum source 15 136, the portions of the sheet of material 12 generally near each of the corners of the object of,material 12 are '~ biased or pulled generally toward -the respective inclined support surfaces 126 when the sheet of material 12 ini-tially is placed or positioned on the upper support surface 20 122. The amount of vacuurn applied through the hold openings 134 is relatively sligh-t so the vacuum tends to bias or pull the portions of the sheet of material 12 generally near the corners toward the respective inclined ~ support surfaces 126, ye~ the vacuum is small enough to ;~ 25 permit the corner portions of the sheet of,material 12 to be pulled across the respective inclined support sur~aces 126 toward the opening in the female die ~ during the ~: forming of the decorative flower pot cover 14.

the male die 44 in -the downward directlon 68 toward the female die 94. As the male die moves ln the downward direction 68, the male die 44 moves to a posi-tion wherein the lower end 48 of the male die 4~ (the lower end 56 of the base portion 52) initially engages the portion of the sheet of material 12 disposed over the opening in the fe-male die 94. Since the openings 76 in the male die 44 are connected to the vacuum source 80, the vacuum applied through the openings 76 in the male die 44 biases the en-10 gaged portion o~ the sheet of material 12 contac-ted by the lower end 48 of the male die ~4 into engagement with the lower end 42 of the male die 44, such vacuum holding the~
engaged portion of the sheet of material 12 ~ene:rally against the lower end 48 of the male die 44 during the 15 forming of the decorative flower pot cover 14.

The hydraulic cylinder 66 continues to move the male die in the downward direction 68 pushing portions of the sheet of material 12 generally into the opening in the female die 94 forming the female die surface 100, the 20 holding of the engaged por-tion of the sheet of material 12 against the lower end 48 of the male die 44 substantially preventing the slipping of the sheet of material 12 as the ; sheet of material 12 is moved by the male die 44 in-to the opening forming the female die surface 100. The male die `~ 25 44 Gontinues to be moved in the downward direction into -the opening forming the female die surface 100 to a posi--tion wherein the male die surface 50 is matingly disposed within the female die surface 100 with the lower end 44 ~: of the male die 44 being disposed generally near the lower 30 end 104 of the female die surface 100, portions of the sheet of material 12 being disposed generally about the male die surface 50 and generally between the male die sur-face 50 and the female die surface 100 in the forming posi-:.~

tion of the male die 44 within the -female die surface 100.

The vacuum applied through -the hold openings 134 in the inclined support surfaces 126~ permits the portions of the sheet of material 12 disposed generally over the in-clined support surfaces 126 to be biased toward such in-clined support surfaces 126 and ye-t to be slidingly moved in the direction generally toward the opening in the female die 94 forming the female die surface 100 as the male die 44 engages the sheet of material 12 and pushes the sheet of 10 materi.al 12 into the opening forming the female die sur-face 100 as the male die 44 is moved to the forming posi--tion. In the forming position of the male die 44, the vacuum applied through the hold openings 134 in the inclined support surfaces 126 cooperate to hold the four corner por-15 tions of the sheet of material 12 generally against the ; respective inclined support surfaces 126 during the -forming of the decorative cover 14 with portions of the sheet of '~ material 12 being disposed generally over the ribs 142 on each O:e the flat portions 140 of the support surface 122.
;

In the forming position of the male die 44 within the opening forming the female die surface 100, the base portion 106 of the female die 94 cooperates with the base portion 52 of the male die 44 to form the portion of the sheet of material disposed therebetween into the base 26 25 of the decorative flower po-t cover 14. The flared portion 112 of the ~emale die 94 cooperates with the flared portion ~:~ 58 of the male die 44 to form the portion of the sheet of : material 12 disposed therebetween into the lower portion of the decorative border 34 generally adjacent:the upper end 30 28 of the base 26~ thereby establishing or forming the angle at which the decorative border 34 extends upwardly and outwardly from the opened upper end 28 of the base 26.

The four flared petal-like portions 36 o~ the decorative border 34 are disposed on the respec-tive inclined support surfaces 126 during the forming of the decorative cover 14.
The vacuum applied at the hold openings 142 biases the four corner portions of the sheet of material 12 against the respective inclined support surfaces 126 which tends to pull or hold the four corner portions from being pushed in-to the opening in the female die 94, although the vacuum is slight which permits the four corner portions of the 10 sheet of ma-terial 12 to slide over the inclined support sur-faces 12 toward the opening in the female die 94 during the forming process. This action on the four corner por-tions o~ the sheet o~ material 12 tends to keep overlapping portions or overlapping folds from forming in the petal-15 like portions 36 of the formed decorative flower pot cover14, The ribs 142 in the -flat portions 140 of the support surface 122 tend to form elongated outwardly extending waves or non-bonding loose overlaps or folds in the flare connecting portions 40 of the formed decorative -flower pot 20 cover 14. The waves or loose non-bonding overlaps or folds tend to pull portions of the material toward the flat por-tions 140 and generally away from the inclined support surfaces 122 which contributes to maintaining the four cor-ner portions of the sheet of material 12 forming the petal-25 lil~e portions 36 substantially flat and free of folds.

In a preferred form, the control valve 88 includesa timer which is constructed and adapted to keep the air supply 86 connected to the hydrauIic cylinder 66 for holding the male die 44 in the iorming position with re-` 30 spect to the female die 94 for a predetermined period of ; time which, in one embodimentS is about three seconds, for example, the particular time being sufficient to form the decorative flower po-t cover 14 and to permit the bonding of : ;, - .

95~i~

the overlapping folds 42. At the end of this predetermined period o~ time, the control valve 88 is moved to connect the air supply 86 to the lower end o~ the hydraulic cylin-der 66, thereby causing the male die 44 to be moved in S the upward direction 70.to the storage position. As the male die 44 is moved in the upward direction 70.to the storage position, the.vacuum applied through the openings 76 in the male die 44 holds the formed cover against the :~ male die surface 50 or, more particuIarly, holds the closed 10 lower end 30 of the formed decorative cover 14 against the lower end 48 of the male die 44. When the male die 44 has . been moved to the storage position, the control valve 84 is positionecl to connect the blower 82 to the openings 76 in the male die 4~ thereby releasing the formed cover from 15 the male die sur~ace 50 so the formed decorative flower pot cover 14 easily can be removed or released from the male ~; die 44 -for conditioning the cover forming system 10 to form ~: another decorative flower pot cover 14.
;
The surface area of the portions o-f the sheet of 20 material 12 which is pushed into the base portion 106 of the f`emale die 94 and which is utilized to form the base 26 of the decorative flower pot cover 14 exceeds the sur-face area of ei.ther the base por-tion S2 of the male die sur-face 50 or the base portion 106 o-f the ~emale die sur-: : :25:face 100 or the outer peripheral surface including the bot-: ~ tom~of the flower pot:object 16.: This excess ma-terial utilized to iorm the base 26 during the forming process is : utili~ed to form the overlapping folds 42.

It should be noted that~ in one embodiment, the s ~ : ~ 30 vacuum source 136 actually is a blower-which is connected . ~ .
::~ to the conduit in such~a manner as to impose a slight vacuum through the hold openings 142. Also,.it should be noted .

' "' '"" ';

~!L2~

that, in one embodiment, the system 10 does not include the b].ower 82 and, in this embodiment, the valve 84 is posi-tioned to disconnect the vacuum source 80.from the openings 76 in the male die 44 when the male die 44 is moved to the storage position. In this embodiment, the formed decora-tive flower pot cover 14 is released from the male die 44 by the weight of the formed decorative flower pot cover 14, the formed decorative flower pot cover 14 simply falling off the male die 44. Further, the vacuum source 80 also ~0 may be a blower which is connected to the conduit 78 in such a manner as to impress a vacuum at the openings 76.

It sllould be noted that, in some applicati.ons, the flower pot cover 14 may be formed without using the vacuum source 80 applied at the openings 76 in the male die 44.
~ 15 However, it has been found that the friction between the ;~ male die surface 50 and the engaged portions of the sheet of material 12 varies thereby causing the male die 44 to push the sheet of material 12 into the female die surface : 100 in an uneven manner. This difference in friction also 20 may results -from using different materials to form the sheet of material 12. In any event, the vacuum applied through the openings 76 holds the engaged portion of the . sheet of material 12 against the bottom or lower end 48 of the male die 44 so the male die 44 pushes the engaged sheet 25 of material 12 evenly into the female die surface 100 which contributes to the forming o-f -the decorative border ~ 34 having a substantially square appearance in a plan view : as shown in Figure 3B.
,:
In some applications, it has been found to be de-30 sirable to form an opening in the lower end 104 of the fe-male die 94. A pad (no-t shown) is disposed in such opening and the pa1 ~s connected to a hydrau1ic cylinder (not , ..
,, . ;
:

shown) which is disposed generally below the female die 94.
During the operation, the hydraulic cylinder moves the pad up to a position wherein the pad is generally coplanar with the upper end 96 of the female die 94 and the male die 44 then is lowered toward the engaging position af-ter the sheet o~ material has been positioned on the support surface lZ2 with a central portion of the sheet of material being disposed generally over the pad. The lower end 48 oL the male die 44 initially engages the sheet of material 10 and a portion o~ the sheet of materia'l is compressed gen-erally between the lower end 48 o:E the male die 44 and the pad. The male die 4~ then further is moved toward the forming position pushing the pad back into the opening in the lower end 104 of the female die 44~ Thus, -the pad and 15 the lower end 48 o~ the male die 44 cooperate to hold the ;sheet of material as the male die 44 and the female die 94 are moved into the forming position.

The platform 120a includes four hydraulic cylinders 142 and a rod of each of the hydrauIic cylinders 146 is connected to one oi the inclined support surIaces 126a.
The hydraulic cylinders 146 are connected to the air sup-ply ~6 (shown in Figure 1) and a control valve (not shown) 10 is interposed be-tween the air supply,86 and the hydraulic cylinders 146.

In one position, the air supply 86 is connected to the hydraulic cylinders 146 for moving the inclined support surfaces 126a connected thereto in an upward direction to 15 move the inclined support surfaces 126a from a horizontally disposed position to an operating position and, in one other position, the air supply 86 is connected to the hy-draulic cylinder 146 for moving the inclined support sur-faces 126a connected thereto in the downward direction to 20 move the inclined support sur~aces 126a from the operating position to the storage position wherein the i~clined sup-port surfacss 126a each are disposed in a substantially horizontal plane.

After the sheet of material 12 has been positioned on the support surface 122a, then the air supply 86 is connected to the hydraulic cylinders 1~6 for moving the inclined sup-port surfaces 126a connected thereto to the forming posi-tion wherein each inclined support surface 126a is angularly 10 disposed with respect to the remaining portions o~ the sup-port sur~ace 122a. When the inclined support sur~aces 126a each have been moved to the forming position, the sheet o~ material 12a partially supported on the inclined support surfaces 126a then can be formed into the decorative 15 flower pot cover 14 in a manner exactly like that described be~ore with respect to the platform 120 shown in Figures 1 and 2. After the decorative flower pot cover 14 has been formed, then the hydraulic cylinders 146 are connected to the air supply 86 for moving the inclined support surfaces 20 126a connected thereto in the downward direction until each o~ the inclined support sur~aces 126a is disposed in the storage position extending in a substantially horizontal plane coplanar with the horizontal planar disposition of the remaining portion of the support surface 122a.

L`ore with respect to the system 10 shown in Figures 1 and 2, thereby ~orming the decorative flower pot cover 14. While : the decorative cover 14 is formed at station "B", another sheet of material 12 is cut from the roll of film 234 and operatively disposed on the support sureace 122a associated with the Cemale die 94 located at station "A".

After the decorative flower pot cover 14 has been formed at station "B", the tables 200 and 212 are rotatingly moved by the table drive assembly 217 to position the male and female dies 44 and 94 which previously were located at 10 station "B" at stat~.on "C" 9 thereby positioning the formed flower pot cover at station "C". ~t station "C", the male die 44 is moved in the upward direction to -the s-torage posi-tion with the vacuum applied via the vacuum source 221 holding the formed decorative flower pot cover 14 on the 15 male die 44 in the manner like that described before with respect to the system 10 shown in Figures 1 and 2. At station "C" and after the male die 44 is moved to the sto-rage position, the unloading drive 250 is activated to move the unloading arms 252 and 254 in the direction 258 to the 20 unloading position and, when the unloading arms 252 an~ 254 have been moved to the unloading position, the vacuum ap-plied by the vacuum source 221 is:disconnected from the male die 44 at station "C" thereby releasing the formed decora-~: : tive ~lower pot cover 14 from the male die 44. When the 25 formed decorative flower pot cover 14 is released from the : male die 44 at station "C", the released cover 1~ is dis-;~ : posed with or between the arms 252 and 254 with the decora-~ tive border 34 operating to preven-t movement Oe the cover : : 14 through the space between the arms 252.and 25~ so the 30 arms 252 and 254 cooperate to hol.d the formed decorative :~
flower pot cover 14. In this position of the formed cover 14, the unloading drive 250 is actuated to move -the arms :: ' , , .

252 and 254 in the direction 256 to the unloading position wherein the formed cover 14 can be removed from -the arms 252 and 254 for disposing the formed cover 14 in shipping boxes for disposing the -formed cover 14 for further proces-sing. In the unloading posi-tion, the arms 252 and 254 can be pivotally dropped by unlocking the hinge 255.

After the formed cover 14 is removed from the male die 44 at station "C", the tables 200 and 212 again are rotated in the direction 220 to position the male and female 10 dies 44 and 94 which were at station "C" at station "D".
At station "D", the vacuum is reapplied to the male die 44 located at station "D" and the male and female dies 44 and 94 located a-t station "D" are conditioned to again form : another decorative flower po-t cover 14.

.~ 15 The system lOc is constructed to sequentially move the male dies 44 and associated female dies 94 to the ~ stations "A", "B", "C" and "D". The processes just de-.;~ scri.bed which occur at each of the respective stations "A'i, "B"~ "C" and "D" continuously occur so the system lOc pro-: 20 vides a more automated process for -forming the decorative flower pot covers 14.

Embodiment of Figures 7A and 7B

Shown in Figures 7A and 7B is a modi-fied system lOb which ls constructed and operates exactly like the sys-tem ~ 25 10 shown in Figures 1 and 2 and described in detail beforeJ
-.~ except the system lOb includes a modified support assembly 72b. The support assembly 72b includes a post 150 having one end supported on the -floor 7~ and extending a distance upwardly therefrom terminating with an upper end portion.

A rod is reciprocatingly disposed in a hydraulic cylinder 156 and the rod is connected to the beam 154. The hydraulic cylinder 156 is connected to the air supply 86 (shown in Figure 1) and a control valve (not shown) is in-terposed between the air supply 86 and the hydraulic cylin-der 156 for controlling the operation of the hydraulic 10 cylinder 156. In one position, the air supply 86 is con-nected to the upper end of the hydraulic cylinder 156 Eor pivotally moving the beam 154 in the direction 160 and, in one other position, the hydraulic cylinder 156 is connected to the control valve 158 for pivotally moving the beam 154 15 in the direction 162.
,~
The modified system lOb will operate to Eorm the decorative flower pot cover 14 in a manner exactly like that described beEore with respect to the system lO.shown in Figures 1 and 2, except the air supply 86 initially is con-~: 20 nected to the hydraulic cylinder 156 for moving the beam : in the direction 162 to the forming position wherein the male die surface 50 is supported a distance above and generally over the female die surface 100. In this posi-tion of the beam 154, the system lOb is operated exactly : 25 like the system~lOa to form the decorative flower pot : cover.

~2~i~5~3 4~ of the male die 44, the hydraulic cy:linder 156 is con-nected to the air supply 86 for moving the beam 154 in the direction 160 to the cover disposing position. When the beam 154 has been moved to the cover disposing position, then the control valve 88 is positioned to connect the openings 76 to the blower 82 -For releasing the enga~ement between the formed decorative flower pot cover 14 and the male die 44 for removing the formed decorative flower pot cover 14 from the male die ~4. The movement of the beam 10 154 to -the cover disposing position permits the formed de-corative flower pot cover 14 to be moved to a diEferent position with respect to the forming position which may be more convenient in some applications for releasing the formed decorative flower pot cover 14 more directly into 15 subsequent process steps such as boxing for shipment, for ~; example.
~' The following are examples of techniques for making ~ decorative covers 14 in accordance with the present inven-; tion.

In one example, a sheet 0.83 gau@e polypropylene is acrylic coated on both surfaces, one surface coating being tinted with color and the opposite surface being opaque in some instances and being clear in some other instances (particularly preferable when the other surface is clear or 2S tinted yellow, for example). A clear polypropylene sheet is interleaved with the tinted or: colored sheet of material, this sheet being acrylic coated on both surfaces. The two sheets then are bonded together to form the sheet of material 12. The coloring inks may be acrylic, hea-t seala-30 ble as described above or may be modi-fied nitrocellulose heat sealable.

In another example 9 a 1.32 gauge polypropylene sheet is acrylic coated on both surfaces, one surface coating being tined with color and the opposite surface coating being opaque colored in some ins-tances and left clear in some other instances (particularly prefereable when the opposite surface is tinted white or yellow)~ This sheet then is laminated and adhered to a second sheet of Saran coated polypropylene or uncoated polypropylene mate-rial using the acrylic heat sealing inks or the modified 10 nitrocellulose inks as the adbesive mentioned before.

In another example, a sheet O:e Saran coated poly-propylene or uncoated polypropyle~e o~ material is tinted on one sur-face with a color and on the opposite surface of the same sheet opaque colored in some instances or clear in 15 some other instances (particularly preferable when tinted white or yellow) A second sheet of clear polypropylene acrylic coated material is adhered to the first shee-t.
Various inks (coloring) are added to the acrylic adhesive or the modified nitrocellulose adhesive, both heat sealable.

In another example, a Saran coated polypropylene or uncoated polypropylene is tinted on one surface with a chosen color using a pressure sensitive rubber based adhe-sive colored as the opaque surface. This first sheet then is adhered to a second clear sheet of Saran coated or un-25 coated polypropylene.
:
In another example, a first sheet of uncoa-ted poly-propylene is tinted with a color on one surface wi-th the opposite surface being opaque coloring or, in some in-stances, left clear, particularly when the opposite surface 30 is tin-ted or colored white or yellow. ~ second Saran coated polypropylene sheet is adhered to this first sheet.

~; ;; . ' , .", , .

'. ;' '; ,~' ' ~' ;

~L2~S5~3 ~o -Inks are added to the acrylic or modified nitrocellulose adhesive for coloring, both adhesive being heat sealable.

In another example~ a first sheet of polypropylene Lilm is adhesively connected to a paper laminate with the appropriate coloring and metal finishes to provide a sheet of material 12 having an overall appearance similar to aluminum foil9 for example, and which has dead-fold charac-teristics or properties.

In another example, a foil sheet is adheslvely con-10 necte~ to an uncoated polypropylene sheet with an inter-leaved third polypropylene sheet which is adhesively coated (heat sealing adhesive) on both surfaces. In some in-stances the foil is prepainted and, in some instances the three layer sheet o-f material 12 is embossed wi-th a pre-15 determined pattern.

In another example,a single foil sheet may beutilized to form the article with an adhesive applied to one or both surfaces thereof and,in some applications, the adhesive coating may be eliminated since the foil has dead 20 fold characteristics or, in other words, since the foil is shape sustaining.

In another example, the sheet of material is formed with a first polypropylene sheet layered on a second poly-propylene sheet, the first sheet may be adhesively coa-ted ; 25 on one or both surfaces and the second sheet may be adhe-sively coated on one or both surfaces. For example, the first sheet may be adhesively coated on both surfaces and the second sheet may be adhesively coated on one surface, opposite the surface disposed adjacent the first sheet so 30 the sheet o-f material 12 comprises the first and second ., :: . .

sheets with an adhesive coating on the opposite surfaces of the sheet of material 12. In this last mentioned example, the second sheet may not be coated so only the coating on the one sur~ace of the -first sheet is exposed in the finished sheet of material 12 or the coatings may be re-versed with respect to the frist and the second sheets so only the adhesive coating on the second sheet is exposed on the finished sheet of material. In this example, the first and second sheets may be adhesively connected to form the sheet of material 12 prior to forming the decorative cover 1~ or the first and second sheets may be layered and adhesively connected during the forming of the decorative cover 14.

The polypropylene sheet or film is relatively thin ` 15 having a thickness in a range -~rom about 1.0 mills to about 1.5 mills and, thus, a sheet of material 12 formed by layering and adhesively connecting a first and a second shset of poIypropylene sheets or films has a total thickness in a range rom about 2.0 mills to about 3.0 mills. The :` ~
~; 20 thickness o~ a sheet of polypropylene film varies and, in additlon, the thickness will vary depending on the thick-ness of the adhesive coating applied to the sheets to be ~: utilized in making the sheet of material 12.

In addition to being relatively thin, the polypro-pylene sheet does not have any substantial dead fold charac-teristics or, in other words, shape sustaining charac-teris-~:: tics. Thus, when this type of material is formed into any particular shape, such as the decorative cover 1~, the formed sheet o~ material tends to return -to the unformed state with constraints are removed. In addition, -the :~ strength of the polypropylene sheet is not suffici.ent to ~: sustain the ~ormed shape which combines with the lack of .~, ;: ' . ~ .;,' , : ' ,:, - .
~. . .

~z~

dead fold characteristics to render it extremely difficult to utilize this material in making preformed articles or covers.

In another example, a first sheet o~ polypropylene film has a transparent color printed on one surface thereof and a metallic ink is applied to one surface of a second sheet of polypropylene film. The color and the metallic in~ may be incorporated with the adhesive coating if the adhesive coating is to be applied to that surface of the 10 sheet. The first sheet with the transparent color forms the outer or lower surface ~3 of the cover 14 and the se-cond sheet with the metallic ink forms the inner or upper sur~`ace 41 of the cover 1~, the combination of the transpa-rent color along with the metallic ink or finish provides 15 a finished, preformed article formed of a sheet of material 12 comprising two polypropylene films, but also having an overall metallic appearance. In lieu of metallic inks, the metallic finish can be applied to the ~ilm by metalizing one surface of the film or by adhesively connecting a ~ilm 20 to a foil, for example.
: .
The present invention provides a means for forming an article, a sheet of material 12 formed using one sheet of polypropylene material or two or three layered and ad-hesively connected sheets of polypropylene material. The 25 overlapping folds 42 which extend various distances and at various angles over or about the formed article provide the strength required for the formed sheet of material 12 to sustain the formed shape. The overlapping folds 42 formed in this manner provide a uniform resistance and a uniform 30 ~lexibility and give the ~ormed portion of the sheet of materiaI 12 the greatest overall strength per unit mass, the random ~orming oi` the overlapping ~olds 42 provlding a ,, :, :. , .

, :,' ,:,. '; . ' : . , ~2~9~

close approximation to a uniform thickening-like action thereby allowing thin, non-shape sustaining sheets or films to be utilized in forming articles while resulting in a substantial shape sustaining, relatively thin, article.

The particular films mentioned before were corl-structed of a polypropylene film. However, such films also could be polyvinyl chloride films which have the advantage of being inherently heat sealable with respect to like materials.

The sealing O:e one film to another or the sealing o~ the overlapping folds ~2 also can be accomplished uti-lizing a heat sealable lacquer, a pressure sensitive adhe-sive which may or may not also require heat, a heat seala-ble adhesive described before, a hot melt adhesive, wax, 15 solvent, a light activated adhesive or other means of chemically connecting two sheets. The adhesive material can be applied to the sheets by gravure, flexographic, let-ter press, spray or other means for applying adhesive to ; films.

The films utilized to form the sheet of material 12, described before, are substantially waterproo~ so the pre~ormed article also is waterproof. Also, these films have the ability of being flame retarded.

~hen decorative flower pot covers 14 are formed in 25 accordance with the present invention, as shown in Figures 3A and 3B, the preformed covers 14 may be flattened for shipping and storage purposes and the covers 14 then may be unflattened for display or sale or both. The decorative flower pot covers 14 formed in accordance with the present 30 invention easily are unflattened to assume the original .. ..

-~4-preEormed shape without any substantial loss oE the pre-: formed shape, thereby providing a flexible~ yet shape sus-taining article. The ilattened covers 14 occupy about one-third oE the space as compared with stacked covers 14 which reduces shipping costs and storage space.

After the decorative flower pot cover 1~ (shown in Figures 3A and 3B) is Eormed, the decorative border 3~ is Eormed by trimming the edges to the desired shape, the de-corative Elower pot cover 1~ shown in Figures 3A and 3B
10 being trimmed -to a square sh~pe. The particular shape depends on the eE:eect desired and the shape may be round, scalloped or heart shaped, ~or example. ~lso, the border ~- 3~ may be trimmed in a round shape by cutting the border 34 in the round shape generally near the upper end 28 oE the 15 base 26 and, in this embodiment, -the cover 14 may be used as a ~lower pot cover or a hat, such as a St. Patrick's Day hat, for example, with appropriate decorative ef-fects added.
The trimming of the border preEerably is accomplished uti-lizing a wire Eormed in the desired shape which is connected 20 to an electrical supply ~or heating the wire. The formed cover 14 then can be passed through -the opening formed by the wire with the heated wire contacting the border 3~ and eEEecting the desired cut or, in the alternative, the heated wire can be passed over the cover 14 to contact the border 25 3~ at the appropriate position to ef-fect the desired cut.

Changes may be made in the various elements, compo-nents, parts and assemblies described herein or in the steps or sequence of steps in the methods described herein with-out departing Erom the spirit and scope oE the invention 30 as ~e~ined in the ~ollowing claims.
