FRAN KENSTEIN cARToNs May 20,- 1958 4 Sheets-Sheet 4 Filed Aug. 26, 1950 United States Patent O M' CARTONS William G. Frankenstein, Cincinnati, Ohio, assigner to William P. Frankenstein, Roselawn, Ohio Applicafiun August 26, 195o, serial No. 181,677 z Claims. (cl. 229-34) This invention relates to improvements in boxes or cartons and particularly to a knocked-down box or carton wherein the walls are outwardly and upwardly disposed whereby the open upper end of the box or carton has a dimension, at least in one direction, greater than the same dimension along the bottom of the carton in the direction aforesaid.

Boxes or cartons of this general description are old in the art in both cardboard and wood but in the past were of the set-up variety and not knocked-down. By knockeddown construction is meant where the carton or box is partially assembled and shipped in the flat to the ultimate user. 1n the past the said boxes or cartons of the general type of the present invention had their walls of sin-v gle material thickness and can probably be best exempliied by the boxes or cartons generally referred to as berry baskets.

Bythe present invention the berry basket is provided of foldable material such as cardboard, paste-board, flexible transparent material, and the like, and in a knocked-down condition to be set up by the user and when so set up is provided with walls of considerable thickness and with the said walls hollow and composed of spaced apart inner and outer wall members.

It is therefore the principal object of this invention to provide a carton or box having hollow or spaced apart walls with at least two opposed walls upwardly and outwardly aring.

Another object of this invention is the provision of a box or carton that will accomplish the foregoing object and wherein the said box or carton is supplied to the user in a knocked-down condition so that the same may have its walls readily erected and locked in erected positions.

A further object of this invention is the provision of a carton or box formed of a single blank of foldable sheet material and wherein each of the walls are of hollow or spaced inner and outer wall members and upwardly and outwardly liare from the carton bottom whereby the open top covers a greater area than the exposed bottom at the lower ends of the walls.

A still further object of this invention is the provision of a box or carton for accomplishing the foregoing object which can be shipped to the user in a knocked-down condition to be readily erected by said user.

Other objects and advantages of the present invention should be readily apparent by reference to the following specification considered in conjunction with the accompanying drawings forming a part thereof and it is to be understood that any modications may be made in the exa-ct structural details there shown and described, within the scope of the appended claims, without departing from or exceeding the spirit of the invention.

Fig. 20 is a transverse sectional View through the carn of Fig. 18 as seen from line 20-20 on said Fig. 18.

Throughout the several views of the drawings similar reference characters are employed to denote the same or similar parts.

The drawings illustrate three modiiications or exempliications of the invention which will be described in succession with successive modifications having pointed out the specific details therein over the other modifications.

Accordingly, the modilication disclosed in Figs. 1 to 5, inclusive, includes a one-piece blank having substantially centrally thereof a main or bottom panel Ztl having its sides or edges defined by score or fold lines 21, 22, 23 and 24. For simplification in the following description the score or fold lines 21 and 23 will be described as defning the ends of the blank while the score or-fold lines 22 and 24 will be described as defining the sides of the blank. It will be understood that this nomenclature may be reversed since the terms sides are generally reserved for the longer edges of the box or carton while the term ends is ascribed 'to the transverse or shorter edges. The score or fold lines 22 and 24 each, integrally, hingedly connect with the main or bottom panel a similar extension 25 and 26 which in the erected. canon from the side walls while the score or fold lines 2li and 2.3 each, respectively, integrally, hingedly connect with the main or bottom panel 29 extensions 27 and '28 which in the erected carton form the end Walls and which extensions will be described in detail.

Accordingly, and since the side wall extensions. 25.and 26 are substantially identical, it is believed that a description of one extension, extension 26, will sutiice. for both. The extension 26 is provided longitudinally thereof with a plurality of parallel score or fold lines 29, 30 and 31 forming, in said extensions, panels 32, 33, 34 and 35. The panel 32 in the erected carton forms the side wall outer wall member and has its ends defined by score or fold lines 36 and 37 which extend, as seen in Fig. l, downwardly and outwardly from the ends of the score or fold line 24 thereby forming the panel 32, in plan, as an isosceles trapezoid. Hingedly connected to the ends of the panel 32', respectively, by the score or fold lines 36 and 37, are corner pieces 38 and 39 which, as will later be made clear, form bellows corners for the carton.

The panel 33 in the erected carton forms the side wall top wall member or spacer and is of a length equal to the longer side of the panel 32, namely, the score or fold line 29.

In the erected carton the panel 34 forms the side wall inner wall member and has its ends defined by score or fold lines and 41, which like the score or fold lines 36 and 37 are angularly disposed from the outer corners of the side wall top wall member or panel 33. The score or fold lines 40 and 41 instead of being outwardly angularly disposed are inwardly disposed, wherefore, the panel 34, like the panel 32, in plan is an isosceles trapezoid having a position in the blank of the carton reversed to that of the said panel 32. In other words, the longer of the parallel sides of the panel 34 is adjacent the longer of the parallel sides of the panel 32 whereby said panels may l be superimposed on one another to have their parallel sides and non-parallel sides coincident. As will later appear, the said panels 32 and 34 are spaced from one another a distance equal to the width of the panel 33. The panel or side wall inner member 34 has integrally, hingedly connected to its opposite ends through the score or fold lines 40 and 41, respectively, tucking aps 42 and 43 each of which, in turn, has hingedly connected thereto a spacer flap 44 and 45 through, respectively, a score or fold line 46 and 47. The panel or side wall inner wall member 34 is further provided near its outer corners with slots 48 and 49 which are disposed in the panel 34 to be parallel with the score or fold lines 40 and 41 and said slots 48 and 49 cooperate with means for locking the carton walls in their erected positions.

The remaining panel 35 in the erected carton consti-- tutes a glue iiap for securing the inner wall member or panel 34 to thernain or bottom panel 20 land for this purpose the said glue flap 35 has applied thereto adhesive 50 which, in the modification illustrated in Figs. l to 5, inclusive, is applied to the undersurface as seen in Fig. 1.

The end wall forming extensions 27 and 28 are substantially identical wherefore it is deemed suiicient if but one of them be described in detail. Accordingly, extension 27 between the score or fold line 21 and outer extremity thereof is provided with a plurality of parallel score or fold lines 51, 52 and 53 forming in said extension panels 54, 55, 56 and 57. In the erected carton the panel 54 is substantially rectangular in plan and forms the end wall outer wall member and has its ends deined by score or fold lines 58 and 59. The score or fold lines 58 and 59 hingedly connect with the panel 54, respectively, the bellows corner aps 38 or 39. In order that the said bellows corner aps or pieces 38 and 39 may be folded they are respectively provided with a diagonal score or fold line 60 and 61.

The panel 55 in the erected carton forms the end wall top wall member or spacer and, as noted above, is intermediate the panelsk 54 and 56. The panel 56, similar to the panel 54 is substantially rectangular in plan and in v as at 62 and 63 and^which contour may take any suitable or desirable form, that shown in Figs. 1 and 3 simulating rounded corner.

The end wall inner wall member or panel S6 has its ends defined, in part, by score or fold lines 64 and-65 and, in part, by projecting lugs 66 and 67 which are locking lugs for cooperation with the locking slots 48 and 49 in the side wall inner wall members, as will subsequently be made clear. The end wall inner wall member or panel 56 has hingedly connected to its ends, respectively, by the score or fold lines 64 and 65 spacing tabs 68 and 69 which space the vertical edges of the inner wall member from the outer wall member as will subsequently be made clear. The remaining panel 57 constitutes a spacing ap for spacing the lower end of the end wall inner and outer wall members from one another in erected position.

The blank after being formed as above described has the adhesive S0 applied to the glue aps of each of the extensions 25 and 26 whereupon the said glue aps 35 are folded onto the panel 34 on the score or fold line 31, or the said folding of the glue flap is first made whereupon the adhesive 50 is applied thereto. The extensions 25 and 26 are then further folded, respectively, on their score or fold lines 29 to bring the said glue flaps 3S into contact with the main or bottom panel in the position as illustrated in Fig. 1 for the extension 2S. Pressure is knocked-down position is shipped to the user for subse-- quent erection.

The user upon desiring to erect a carton first raisesy the' folded side walls to be upstanding or normal to the main or bottom panel as shown in Fig. 3. The tucking naps" 42 and 43 each now have their spacing aps 44 and 4S bent to be parallel with the main or bottom panel 201' whereupon the said tucking flaps are folded to extendtransversely of the said carton main or bottom panel as illustrated by the left-hand tucking flap in Fig'. 3'.

The end wall extensions are now erected which consists in successively raising said extensions after iirst folding on themselves the bellows corner pieces or iiaps 38v and 39 and disposing the said folded corner pieces transversely of the main or bottom panel. Each end wall extension is raised until the outer wall member engagesV the outwardly and upwardly extending or aring ends of the side walls, for example, the ends of the panels 32 and 34 as defined by the now aligned inclined score or fold lines 37 and 41. The end wall top wall members or panels 55 are then folded to be parallel with the main or bottom panel 20 and with the contoured ends 62 and 63 thereof resting on the side walls top wall members or panels 33. The inner wall member or panel 56, after having the spacer flap 57 folded to be substantially normal thereto and having the spacing flaps 68 and 69'likewise folded to be substantially normalv thereto, is folded to extend parallel with the end walls outer wall members or panels 54 until the locking lugs 66 and 67 snap into the side wall locking slits 48 and 49.

The carton is now in its fully erected position with the end walls extending upwardly and outwardly as seenin Fig. 4-and with the side walls extending upwardly normal to the carton main or bottom panel 20 as seenin Fig. 5. This results in a carton having an open top with a greater dimension lengthwise than the exposed bottom of the carton lengthwise thereof, while the carton transtion in Figs. 1 and 5 for the end wall inner and outerv wall members and the similar substitution of the rectangular end wall inner and outer wall members of said modification in Figs. 1 to 5, inclusive, for rectangular side wall inner and outer wall members in Figs. 6 to 10.

The elements in the blank in Fig. 6 as compared with the blank in Fig. 1 are substantially the same and the parts in Fig. 6 are identified by the same reference numerals witha prime (8) added thereto.

In the modification in Figs. 6 to 10, inclusive, the glue flaps 3S for the side walls are shown as provided with adhesive S on their upper surfaces and therefore are attached to the main or bottom panel to extend toward the center of said main or bottom panel instead of extending toward the bounding score or fold lines 22 and 24 as illustrated in Fig. 1.

The erected carton in Figs. 9 and 10 shows the carton as having the open upper end thereof longitudinally of the carton as of the same dimension as the exposed bottom or main panel longitudinally of the carton, while transversely the open upper end of the carton is of a greater dimension than the exposed bottom of the carton transversely, thereof and including the glue flaps of the side walls as part of the exposed carton bottom. This is the reverse of the carton resulting from the blank of Fig. 1 and as illustrated in Figs. 4 and 5.-

The modification illustrated in Figs. 11 to 15, inclusive, has incorporated therein the isosceles trapezoid side wall inner and outer wall members of Fig. 1 and the isosceles trapezoid end wall -inner and outer wall members of Fig. 6. Again, the elements of the blank of Fig. 11 are substantially identical with the elements in Figs. 1 and 6, except as modified as just pointed out, and the said elements are identified by the same reference characters with a double prime added.

In the blank illustrated in Fig. 11 a slight further modification includes the substitution of tucking flaps 70 and 71 at the ends of the side walls outer wall members 32" instead of the bellows corner pieces 38 and 39 of Fig. 1. 'I'his results in a cut line 72 between said tucking a'ps 70 and 71 and the end walls inner wall members or panels 54, instead of the score or fold lines 58 and 59 shown in said Fig. 1. The setting up of the blank of Fig. 11 into an erected carton of Fig. 13 is in no wise changed except that the tucking fiaps 70 and 71 need not be folded on themselves prior to the erection of the end wall extensions 27" and 28", instead, requiring only that the said tucking flaps 70 and 71 be disposed transversely of the carton 4main or bottom panel 20, as illustrated at the upper left-hand corner of Fig. 13.

The carton resulting from the blank of Fig. 11 has the end walls upwardly and outwardly flaring, see Fig. 14, as does the end Walls of the carton from Fig. 1 as illustrated in Fig. 4. The carton of Fig. 11 also has the side walls upwardly and outwardly flaring, as illustrated in Fig. 15, as does the side walls of the blank of Fig. 6 and illustrated in Fig. 10. In other words, the carton of Fig. 13 has each of its four walls outwardly and upwardly flaring in the same manner as the heretofore known berry basket.

The blanks of Figs. 6 and 11 are each shipped to the user in their knocked-down position as illustrated by the upper end of said blanks and as further illustrated in Figs. 7 and 12. The user erects the knocked-down blanks of Figs. 7 and 12 in substantially the same manner as he erects the knocked-down blank of Fig. 2 into cartons for open upper end boxes as illustrated clearly in Figs. 8 and 13.

The modification illustrated in Figs. 16 to 20, inclusive, is substantiallyidentical with the disclosure in Figs. 11 to 15, inclusive', except that the side walls are provided with bottom wall members independently of the closure afforded said side walls by the bottom panel itself. In the drawings, similar to the practice resorted to in connecti-on with the modifications in Figs. 6 and 11, the elements, except for the added elements for accomplishing the result of the present modification, are identified by the same reference characters with a triple prime added.

In the blank of Fig. 16 the glue flap 31" constitutes the side wall bottom wall member 73 having oneside thereof defined by the score or fold line 31 and having its other side defined by score or fold line 74. The score or fold line 74 hingedly connects with the bottom panel the glue flap 35'". l

In forming the blank of Fig. 16 and arranging it in its knocked-down position as illustrated in Fig. 17, the glue fiap 35' is first \folded on the score or fold line 74 to lie on the panel 73 to have the adhesive 50" applied thereto, or the said adhesive 50 is applied by appropriate mechanism to the under surface of the glue iiaps 35 prior to its folding on the score or fold line 74. The extension 26 is then folded on its score or fold line 29 into the position illustrated for the extension 25' at the upper end of the figure which brings the adhesive into engagement with the side wall outer wall member 32 4outwardly of the score or fold line 24". The blank -is then in the position illustrated in Fig. 17 and is so shipped to the user.

The user in desiring to set up the blank from the knocked-down position of Fig. 17 to the erected position of Fig. 18, and before following the erecting steps above set forth for the blank of Figs. 1, 6 and 11, first raises the side walls to the positions illustrated in phantom lines at 75 and 76 in Fig. 7. In other words the said side walls are first arranged substantially to their ultimate angular positions relative to one another whereupon the said walls are completely erected with respect to thecarton bottom and said erected walls locked in their erected positions.

It should be noted that each of the blanks of Figs. 1 and 6 can be similarly modified as was theblank of Fig. 11 and illustrated in Fig. 16 to provide a bottom wall member for the side walls and thereby provide knockeddown cartons which may have their side walls erected or arranged prior to the complete erection of the carton itself. l

From the foregoing, it is believed now evident that there has been provided a knocked-down blank erectable into cartons which will have either two opposed sides, two opposed ends, or all sides of a box or carton upwardly and outwardly flaring with respect to the base or bottom thereof.
