Attorney States BOX CONSTRUCTION Chester G. Myers, York, Pa, and (Mo Fibre, Brooklyn, N. Y.; said Fiore assignor to said Myers This invention relates to improvements in a composite box and, more particularly, but without restriction thereto, to a composite box suitable to contain cigars.

inasmuch as cigars are of a fragile nature, it is necessary to provide a relatively strong box to contain the same. Some years ago, when wood was much cheaper in price than it is now, cigar boxes were conventionally made from wood and the various panels forming the box were either glued and/ or nailed together. Due to the fact that cigar boxes are expendable items, and the further fact that cost of wood was greatly increased particularly during the past ten or more years, it is no longer possible to use wood profitably and competitively for making cigar boxes and especially boxes used in the sale of cheaper and popular priced cigars. Accordingly, various types of boxes formed either entirely or principally from chipboard have been used, particularly for inexpensive cigars and, at least to some extent, for medium priced cigars.

In view of the fact that cigar boxes must be quite rigid and strong in relation to the size of the box, many problems are presented in manufacturing boxes of this type from chip board to satisfy customary requirements, especially where the boxes are to be manufactured automatically upon modern box-forming machines. For example, sides having a substantial thickness must be provided not only for strength and rigidity but because it is conventional to close the lid of a cigar box by driving a nail through one edge of a lid into the upper edge of one of the sides thereof and one of the sides must accommodate said nail. The problem is particularly acute, especially where the entire box is to be formed from chip-board material, due to the fact that it is difficult to provide sufiicient frictional engagement in a chip-board box side for the nail which is to hold the lid closed.

To solve the foregoing problem of providing adequate friction for nails to hold the lid closed, and also to attempt partially to satisfy conventional demands for wood in such boxes, boxes have been made wherein the ends and bottom panels have been formed from chip-board and at least one of the sides has been formed from wood while the other has been of wood or prelaminated chip-board stock having a thickness substantially equal to that of the wooden side. However, the cost of assembling such separate wooden side panel to the ends and bottom of such a box is substantial and savings are not as much as might be hoped for from the use of such an appreciable amount of chip-board material.

It is the principal object of the present invention to provide a composite box formed principally from chipboard material of single thickness, for example of 50 point gauge, more or less, and so designing and connecting the bottom panel and end-forming panels, as well as a set of foldably connected side-forming panels, all folded from a blank, die cut for example from said chipboard material, or, if desired, further providing one side-forming panel so as at least to be partially formed from wood and thereby satisfy the requirement of a box having at 2,797,854 Patented July 2, 1957 least a wooden portion in one side panel for purposes of receiving the nail which is driven through one edge of the lid and into said side panel to hold the lid closed.

A further object of the invention is to so design the various foldably connected panels that the bottom, ends, and sides not only may be folded but the lamination of various panels may be effected by folding and gluing the same automatically upon machines requiring a minimum amount of hand operation, the final assembly and fixing of the corners of the boxes similarly being accomplished on automatically operable machines, whereby the cost of such .a box having a partially wooden side is comparable favorably with the cost of boxes made entirely from chip-board stock material.

Still another object of the invention is to provide a novel assembly of foldably connected panels for forming a side of a box of this nature, whereby a laminated side comprising, for example, four thicknesses of single sheet chip-board stock may be formed automatically by folding and gluing the component panels so as to laminate the same into a rigid side, the top and bottom edges of said side having sharp straight corners which either may be covered by a finish sheet of decorated paper or the like, or said edges may be stained or otherwise colored or finished to render the same harmonious with the decorating scheme of the exterior of the box for example.

Still another object of the invention is to provide a box primarily formed from single thickness chip-board stock having a finish sheet of paper on one surface only and various panels which form the bottom, ends and sides of the box are so folded that said finish sheet on the stock will be disposed on all interior surfaces of the box, as Well as on all exterior surfaces thereof except the-normally bottom surface of the bottom panel.

Details of the foregoing objects and of the invention, as well as other objects thereof, are set forth in the following specification and illustrated in the accompanying drawings comprising a part thereof.

In the drawings:

Fig. l is a perspective view of a blank formed from a single sheet of chip-board material, the same being die cut and scored for purposes of various panels thereof to be folded in a manner to provide laminated ends and sides, the bottom surface of the blanks as illustrated in this figure comprising a finish sheet or a finish surface to appear on the interior of the box and the exterior of the sides and ends thereof.

Fig. 2 is a perspective view of a blank such as shown in Fig. l which has had certain panels thereof folded upon other panels and representing an intermediate-stage in the formation of the completed box.

Fig. 3 illustrates the next folding operation following the folding step illustrated in Fig. 2 and shows the ends and both sides of the embodiment of box illustrated therein in the fully laminated condition thereof, this type of blank being adapted to be folded automatically by one type of available folding machine.

Fig. 4- is a perspective view of a completed box formed from the folded blank shown in Fig. 3 after the blank of Fig. 3 has been turned about one of the axes thereof and the sides and ends have been folded to extend vertically from the bottom panel of the box, the ends of the sides and end members of the box being secured together by tapes cemented thereto.

Fig. 6 is a perspective view of the blank shown in Pig. 5 after certain panels which form one side and q other panels forming the end members of the box have been subjected to initial folding.

Fig. 7 is a perspective view illustrating the next operation succeeding that shown in Fig. 6 and wherein the one side panel has been fully laminated, while the second side-forming panel has had a wooden panel afiixed to a single thickness panel of chip-board stock foldably connected to one side edge of the bottom panel of the blank.

Fig. 8 is a perspective view showing the blank illustrated in Fig. 7 turned 180 about one of the axes thereof and the end panels of the box have been folded perpendicularly to the bottom panel thereof, while the side panels are illustrated in process of being folded vertically to the bottom panel.

Fig. 9 is a perspective view of still another embodiment of box-forming blank which has been die cut and scored for purposes of being folded into a box comprising a variation of the embodiment of the invention illustrated in Figs. through 8.

Fig. 10 is a perspective exploded veiw of the blank shown in Fig. 9 after the side and end panels thereof which are formed from chip-board stock have been fully laminated by folding and gluing and a wooden insert is shown in position to be received within a complimentary cavity formed in one side of the laminated and partially folded box blank.

Fig. 11 is a fragmentary horizontal sectional view taken on the line 1l-ll of Fig. 4 and illustrating details of the composite sides and one end of the embodiment of box shown in Figs. 5 through 8.

Fig. 12 is a view similar to Fig. 11 but showing details of the embodiment of box formed from the blank and wooden insert shown in Figs. 9 and 10.

This invention relates to the type of box, but without restriction thereto, conventionally used as cigar boxes and in which the sides and ends of the box are foldably connected to the edges of a bottom panel. Further,

'when the sides and ends are folded upwardly from the bottom panel so as to be vertical thereto, the ends of the sides are received preferably in mortises in the ends of the end members of the box and the ends of said sides are secured to the end members by tapes or other striplike means glued or cemented preferably to the exterior of the sides and end members of the box.

The embodiment of the invention illustrated in Figs. 1 through 4 comprises a box of the cigar type which is formed entirely from a blank 10 which has been die cut and scored on a die cutting machine, it being noted that the blank lid is substantially rectangular whereby sub stantially no waste results in cutting said blank from sheet stock. Stock preferably used is single thickness chip-board of 50 points gauge, more or less, and it is to be understood that any other gauge chip-board or similar stock may be used which is satisfactory to produce a box embodying the herein described and claimed principles of the present invention. Further, the lower surface 12. of the blank ill comprises either a finish surface or a finish sheet of paper or the like which has been laminated to the sheet stock and, as will be seen hereinafter, said finish surface will comprise all interior surfaces of the box and all exterior surfaces of the sides and end members thereof when the blank has been folded into box formation. The use of single thickness chipboard to form the blank 10 and secure a number of panels thereof into permanently laminated form incident to folding the panels into box formation is substan- 'tially more advantageous, costwise, to using prelaminated stock for purposes of providing sides and end members of desired thickness in a box of the type referred to above.

Referring to the blank 10 of Fig. 1, the same comprises a bottom panel 14 to the opposite ends of which pairs of end-forming panels 16 and 18 are foldably connected by rows of scoring 20 and each pair of panels 16 and 18 are connected together by rows of scorings 22. It will be noted that the panels 18 are substantially the same length as the width of the bottom panel 14, while the additional end-forming panels 16 are longer than the other end-forming panels 18 for purposes of forming the mortise recesses 24 when the panels 16 are folded upon the panels 18 and glued thereto or otherwise aflixed as shown in Fig. 2.

The sides of the box to be formed from the blank 10 shown in Fig. 1 each comprise pairs of similar sideforrning panels 26 and 2%, one edge of each of the panels 26 being foldiably connected respectively to opposite side edges of bottom panel 14 by rows of scorings 30. Further, pairs of additional panels 32 and 34 are connected to the opposite ends respectively of the side-forming panels 26 and 28 by rows of scorings 36, these rows being in alignment with each other at similar ends of the side panels 26 and 28 but are slightly offset toward the outer edges of the blank 10 from the rows of scorings 20 which connect the end-forming panels 18 to the bottom panel 14 for purposes to be described.

Each pair of additional panels 32 and 34 are connected together longitudinally by rows of scorings 38. However, in this embodiment of the invention, each pair of side-forming panels 26 and 28 are separated by longitudinally extending slits 49 which extend entirely through the blank lib for the full length of the panels 26 and 28. However, the foldable connections comprising scorings 38 between the various pairs of additional panels 32 and 34, as well as the foldable connections 'of said panels respectively to opposite ends of side-forming panels 26 and 23 by scorings 36, serve to prevent separation of each pair of side-forming panels 26 and 28 from each other.

After the blank 1.0 has been die cut and scored as shown in Fig. 1, it is placed in a folding machine wherein the end panels 16 are folded automatically upon the end-forming panels 18, as shown in Fig. 2, glue or other suitable adhesive first having been applied automatically between the abutting surfaces of the pairs of end-forming panels. Simultaneously, the four pairs of additional panels 32 and 34 are folded along the rows of scorings 36 so as to dispose the same in laminated condition upon the pairs of side-forming panels 26 and 28 to which said additional panels respectively are connected foldably. Glue or other adhesive similarly is placed between the juxtapositioned flat surfaces of these panels and heat and/or pressure preferably are provided to firmly unite the same into stiff, laminated condition. Further, for appearance, as well as strength, the additional panels 32 and 34 preferably are substantially each half the length of the side-forming panels 26 and 28, whereby, when the additional panels 32 and 34 are folded into the positions shown in Fig. 2, what were the outer ends of said additional panels 32 and 34 substantially will abut each other.

The partially folded blank shown in Fig. 2, while in the folding machine, next is operated upon to perform the step to produce the resulting blank shown in Fig. 3. This blank is similar to that shown in Fig. 2 except that the semi-assembled side-forming panels of Fig. 2 are folded along the rows of scorings 38 to dispose the outer sideforming panels 28 uppermost, with the result that all of the additional panels 32 and 34 now are folded inwardly and sandwiched between each pair of side-forming panels 26 and 28. Glue or other adhesive first is disposed between the abutting surfaces of the additional panels 32 and 34 before this final folding of the side-forming panels occurs. The blank now formed, as illustrated in Fig. 3, is turned about one of the axes thereof and a supply of these flat, folded blanks are fed to a set-up machine which operates automatically and one example of which is known in the trade as a Quad-Stayer. Said machine forms the blank of Fig. 3 into the box shown in Fig. 4, wherein the ends of the composite sides are received withplied to the exterior of cigar boxes.

in the mortise recesses 24 and further are connected to said mortised ends of the end members by suitable means such as tape or strips 42 which are afiixed by suitable cement to the sides and end members of the box 44 by said Quad-Stayer.

Due primarily to the longitudinal slits 40 extending entirely through the blank to separate the side-forming panels 26 and 28, and also because of the disposition of these out edges outermost and uppermost on the composite sides 26, 28 of the box 44 as viewed in Fig. 4, the upper edges of these sides may either be covered with a finish paper strip for example, decorative or otherwise, or

said edges may be stained to harmonize with the exterior decorative paper or other sheet material customarily ap- Also, the normal outer edge of blank extending along side-forming panels 28 will be positioned at the exterior lower edges of the composite side members to provide sharp edges at such lower edges of the box. Further, it will be seen particularly from Fig. 4 that the upper ends of the laminated end members 16, 18 project slightly above the upper edges of the composite sides 26, 28 as is customary in cigar box construction for purposes of a lid being disposed upon the upper edges of the composite sides and extending across the box between said sides, while the upper surface of the lid is flush with the upper surfaces of the composite ends 16, 18.

It will be seen from the foregoing that the embodiment of box illustrated in Figs. 1 through 4 is formed entirely from chip-board sheet stock but, due to the unique laminating arrangements which are capable of being formed on automatic machinery, a very rigid and durable cigar box is provided which is extremely economical in cost and is particularly desired by the cigar trade catering to inexpensive or low priced cigars. The sides of this box especially are of substantial thickness and very stiff, readily equaling any conventional cigar box having wooden sides, yet the cost of manufacturing the box shown in Figs. 1 through 4 is substantially less than a cigar box of similar size in which one or both of the sides is formed from wood, even though the bottom and ends of the box may be formed from chip-board stock.

The embodiment of the invention illustrated in Figs. 1 through 4 also may be utilized substantially in providing an improvd box construction suitable to the cigar trade, for example, catering to medium priced or more expensive cigars. In this regard, reference is made to the additional embodiment of the invention illustrated in Figs. 5 through 8 wherein, for example, the blank shown in Fig. 5 is identical with the blank shown in Fig. 1 except that, at one side of the blank, only a single sideforming panel 26 is provided. Said panel 26 however is nevertheless foldably connected by a row of scoring to the bottom panel 14 as in regard to the blank 10 of Fig. 1. Further, the blank shown in Fig. 5, which has been indicated 10 to distinguish it more readily from the blank 10 of Fig. 1, is folded by the same type of machine and. is subjected to the same operations as the blank 10 of Figs. 1 through 3, such folding and intermediate arrangements of the various panels of the blanks of the respective embodiments being similar in that Fig. 6 resembles Fig. 2 and Fig. 7 resembles Fig. 3 excepting that, when the blank 10' has otherwise been folded into the condition shown in Fig. 7, a supply of the blanks is next introduced to an insert machine which automatically applies a wooden strip 46 preferably of the same length and width as panel 26 but being substantially thicker than said panel in the preferred construction of this embodiment of the invention, whereby, for example, the wooden strip 46 may be equal substantially to three thicknesses of the sheet stock of chip-board from which the blank 10' is formed. By such an arrangement, the composite side comprising Wooden strip 46 and chipboard side panel 26 will equal the opposing side-forming 6 panels shown in Fig. 7 which are formed entirely from laminated panels of chip-board stock.

As in regard to the embodiment shown in Figs. 1 through 4, the folded and composite blank 10 shown in Fig. 7, to which the wooden strip 46 has been affixed automatically by glue or other cement against side panel 26, is rotated about one of its axes and then is presented to a Quad-'Stayer for purposes of folding the laminated end members and laminated sides of the box relative to bottom panel 14 and also securing tapes or strips 42 to the corners of the box as in regard to the box 44 shown in Fig. 4.

Further, it will be noted that inasmuch as the blank 10' also has a finish surface or finish sheet 12 affixed to the lower face thereof as viewed in Figs. 5 through 7. Due to the turning of the blank of Fig. 7 about one of its axes 180 to dispose it in the position shown in Fig. 8 and subsequently folding upwardly the end members and sides thereof, said finish surface or finish sheet will be disposed on all interior surfaces of the completed box and also upon the exterior surfaces of the end members and sides thereof except the outer surface of the side panel 26 which is covered by wooden strip 46, as in regard to the embodiment shown in Figs. 1 through 4.

Still another embodiment of the invention is illustrated in Figs. 9 and 10, this being somewhat of a modification of the embodiment shown in Figs. 5 through 8 in that one of the sides of the box is composed of folded and glued chip-board panels, while the other side is provided with a wooden insert sufliciently large so as readily to receive a nail for securing the lid of the box closed. Due to the fact primarily that the cost of wood in cigar boxes noticeably increases the cost thereof over boxes manufactured either entirely or substantially entirely from chip-board stock, it is desirable to use as little wood as possible in a box. However, for providing effective friction to engage and retain a lid-securing nail, it is nevertheless highly desirable that at least a wooden insert be included in the side of a cigar box into which the nail is to be driven.

The embodiment of the invention illustrated in Figs. 9 and 10 comprises a blank 10 which is similar in all respects to the blank 10 of Figs. 1 through 4 and 10' of Figs. 5 through 8, except that one of the side-forming panels 28 is provided with an elongated opening 50 adfjacent the longitudinal strip 40, the opening 50 being scored by the die cutting and scoring machine at the time the blank is formed from sheet stock material. At that same time, the additional panels 32 and 34, on the same side of the blank 10' as the elongatedv opening 50, are respectively provided with notches 52 which face each other, each of these notches being half the area of the elongated opening 50 in panel 28.

The blank 10" shown in Fig. 9 is folded automatically in a folding and pasting machine, similarly to the blanks 10 and 10' in the above described embodiments, the various end-forming and side-forming panels, as well as the additional panels, all being in lamina-ted arrangement and secured together in the manner described hereinabove. When the blank 10 has been folded into the condition shown in Fig. 10, which corresponds respective ly to Figs. 3 and 7 of the foregoing two embodiments, it will be seen that the elongated opening 50 in panel 28 is in vertical alignment with the notches 52 of the additional panels 32 and 34, as viewed in Fig. 10, so as to provide a preferably rectangular notch complementary in size to a wooden insert block 54 which is fitted automatically into said recess by an insert machine and is glued or cemented within said recess, the upper and outer surfaces of said block respectively being flush with the outer surface of side panel 28 and the outer edge of said composite side composed of side-forming panels 26 and 28 and the additional panels therebetween. It is to be understood that the shape of the notch for block 54 and the complementary shape of the block illustrated herein may be varied, as desired.

' After the insertion'of the wooden insert block 54, the blank 10" shown in Fig. 10 then is turned 180 about one of its axes and subjected to a set-up machine such as a Quad-Stayer machine, for purposes of completing the on all exterior surfaces except the bottom surface of the bottom panel 14 and the exposed surfaces of insert block 54. However, the insert block readily is hidden by the addition of a simple strip or sheet of finish paper applied to the exterior and upper edge and outer surface of the side of the box in which the block 54 is included. It will be understood of course that the block 54, as shown in sectional view in Fig. 12, preferably is disposed on the exterior of the box, as is the wooden strip 46 of the embodiment shown in sectional view in Fig. 11 relative to the box construction embodiment illustrated otherwise in Figs. through 8.

While the several embodiments of the invention shown in Figs. 5 through 12 illustrate a wooden member applied only to one side of the box, it is to be understood that both sides of the boxes shown therein may be so arranged, if desired.

From the foregoing, it will be seen that the present invention embodies a plurality of boxes embodying uniquely formed sides and end members which are of a composite or laminated construction formed incident to the folding of a blank die cut and scored from a sheet of single thickness chip-board stock of suitable gauge, whereby, for example, the benefits of prelaminated stock are obtained without the added cost thereof being incurred. Sharp, square edges at the top and bottom of the sides also are provided. Further, several embodiments of the invention also include respectively one side of the box to which has been applied a wooden panel or a wooden insert block into which a nail may be driven for securing the lid of the box in closed condition. However, due to the unique arrangement of the box being formed by folding upon automatic machines a blank which has been die cut from single thickness chip-board sheet stock, the inclusion of such wooden members in the box increases the cost thereof only very slightly over that of a box made entirely from chip-board stock, yet affords the advantage of a wooden anchor member for the nail referred to above. Economy in finish as well as rigidity and durability in construction also are benefits afforded by the various embodiments of the present invention.

While the invention has been shown and illustrated in its several preferred embodiments, and has included certain details, it should be understood that the invention is not to be limited to the precise details herein illustrated and described since the same may be carried out in other ways falling within the scope of the invention as claimed.
