HIGH STRENGTH PAPERBOARD CONTAINERS 15 Sheets-Sheet 15 Filed May 9, 1958 BY ATTORNEYS United States Patent O 3,118,587 HIGH STRENGTH PAPERBARD CONTAINERS Charles D. Welshenbach, Sandusky, Ohio, assigner to West Virginia Pulp & Paper Company, New York, NX., a corporation of Delaware Filed May 9, 1958, Ser. No. 7 34,230 Claims. (Cl. 229-23) This invention relates to paperboard containers and more particularly to containers or cartons that have strength and rigidity enough to make them suitable for use as shipping and storing containers for shipping and storing loose heavy articles such as nails, bolts, nuts, screws or the like, or for shipping other materials.

The present invention may comprise an inner box and cover box of identical construction except that the cover box is made slightly larger than the inner box so that its-internal dimensions correspond to the external dimensions of the inner box to permit it to telescopically receive the inner box.

The inner box and cover box may be formed from a substantially rectangular web section, and each has an end wall strongly united to the upright side walls, two adjacent side Walls being single ply walls and the other two adjacent side walls being double ply walls.

The inner box and cover box may be so shaped that they can be intertitted only when the double ply walls of the cover box are contiguous to the single ply walls of the inner box and the single ply walls of the cover box are contiguous to the double ply walls of the inner box.

Containers having some of the above features have been previously provided. However, the present invention relates to box structure wherein these features are provided in a manner which enables the cover box and inner box to be shipped in a collapsed condition to thereafter be erected by the user without the necessity of the user employing any -stapling or gluing or other equivalent fastening means whatsoever. Previously provided containers having some of the features mentioned above are extremely durable and lend themselves Well to uses where high strengths are required, but they cannot be shipped in a collapsed position and then used Without the user employing stapling or gluing or other fastening operations in erecting the container.

It is entirely conceivable that in some circumstances and for some applications the user of containers contemplated by the present invention may not wish to have the containers pre-stapled, pre-glued or pre-fastened by the manufacturer. Even aside from the feature of being erectable from its collapsed position without fastening operations, the invention represents a significant contribution to the field of packaging due to its economy, its high stack strength which compares Iwith the best containers of the prior art, and its usefulness in many packaging applications.

In another significant aspect, the invention contemplates containers which do not comprise a composite container consisting of a cover box and an inner box but which comprise a single box of the same or similar structure as each of the parts of the composite container. Such single box is provided with end flaps and may be preferably additionally provided with a liner. Such type of container has been found to lend itself very well to packaging of relatively small amounts of loose heavy materials such as nails or other matter.

Other objects, uses and advantages will become apparent from the following description.

Referring to FIGURES 1-6 of the accompanying drawings, the illustrated container may comprise an inner box or unit and a cover box or unit, the two boxes or units being preferably of equivalent construction except for the slight diierences in dimensions necessary to permit the cover box to fit closely over the inner box.

In order to distinguish the parts of the inner box from the parts of the cover box where the two are in assembled relation while at the same time showing the similarity between the two boxes, the parts of the inner box are designated with the same reference numerals as the corresponding parts of the cover box with the addition of the reference character a.

The cover box or unit of the present invention is preferably vertically elongated and has adjacent, upright, single ply walls 1 (not seen in FIGURE 1) and 2. The other walls of the box are double ply walls having outer plies 3 and 4 and inner plies 5 and 6, respectively. Single plies (1 and 4) of two adjacent side walls (1 and 4, 6) are hinged to and integral with each other and also each is hinged to and integral with another ply (2 and 3 respectively) of another of the side walls (2 and 3, 5) respectively). The side Walls will therefore be seen to comprise four rectangularly disposed walls with a pair of the side walls being double ply, the remaining pair of the side walls being single ply, and each member of each of such pairs being adjacent to the other member of its pair.

The end wall of the cover box or unit comprises an inner ply 7 and an outer ply 8. Each of the plies 7 and 8 is hinged to and integral with one ply on each of a twosome of opposite side walls. Thus, the ply 7 is hinged to and integral with Vthe inner ply 5 of the double ply side wall 3, 5 and also is hinged to and integral with the single ply side wall 1. The ply 8 is hinged to and integral with the inner ply 6 of the double ply side wall 4, 6 and also is hinged to and integral with the single ply side wall 2.

In the particular structure illustrated, the plies 2 and 3 are joined by a seam or ap 9 which is integral with the ply 2 and is suitably fastened to the ply 3 by stapling, as shown, or by gluing or other suitable means.

The cover box may be provided with handles (not shown) if desired. An appropriate type of handle structure is shown in U.S. Patent No. 2,761,610.

The inner box or unit of the present invention is preferably vertically elongated and has adjacent, upright, single ply side walls 1a and 2a. The other walls of the box are double ply, having outer plies 3a and 4a and inner plies 5a and 6a, respectively. Single plies la and 4a of two adjacentV side walls (1a and 4a, 6a respectively) are lhinged to and integral with each other and also each is hinged to and integral with another ply (2a and 3a respectively) of another of the side Walls (2a and 3a, 5a respectively). The side walls will therefore be seen to comprise four rectangularly disposed walls with a pair of the side walls being double ply walls and the remaining pair of the side walls being single ply walls, and each member of each of such pairs being adjacent to the other member of its pair.

The end wall of the inner box or unit comprises an inner ply 7a and an outer ply Sa. Each of the plies 7a and 8a is hinged to and integral with one ply of each of a twosome of opposite side walls. Thus, the ply 7a is hinged to and integral with the inner ply 5a of the double ply side wall 3a, 5a and also is hinged to and integral with the single ply side wall 1a. The ply 8a is hinged to and integral with the inner ply 6a of the double ply side wall 4a, 6a and also is hinged to and integral with the single ply side wall 2a.

The plies 2a and 3a are joined by a seam or iiap 9a which is integral with the ply 2a and is suitably fastened to the ply 3a by stapling or by gluing or by other suitable means.

When the cover box or unit and the inner box or unit are telescoped together with their closed ends at opposite ends of the resulting container, the double ply side walls of each box are positioned against the single ply side walls of the other box to provide a container having four triple ply side walls and two double ply end walls.

` The width of the plies 7, 8, 7a and 8a between their bounding hinge lines is such as to cause the plies 5, 6, 5a and 6a, respectively, in the erected condition of the structure, to be positioned immediately and snugly adjacent the inner sides of the plies 3, 4, 3a and 4a, respectively. The transverse width of the plies 5, 6, 5a and 6a is preferably such as to cause the side edges of these plies to snugly engage the plies or walls against which these edges abut in the erected condition of the carton.

The cover box may be shipped in the collapsed condition shown in FIGURE 5A. It is erected by the end user Without any fastening operations by following the sequences of steps shown in FIGURES 5B to 5F. The

Vbox may be shipped in a different collapsed state by extending the two long aps, one of which consists of the `members 5 and 7 and the other of which consists of the wardly when the box is empty and separated from its partner box. However this may not be done when the cover box and inner box are telescoped together. In use, there will rarely be occasion to so collapse the structure, but the structural features which render the structure so collapsible also render it readily erectable without fastening operations, and this latter feature is of Significance, as earlier explained.

it should be clear that for the cover box or unit shown in FIGURES l-S, and similarly for the inner box or unit, the plies 1 4 or liz-4a constitute four adjacent rectilinear tube-forming panels, the two laterally extreme panels of the four (2 `and 3 or 2a and 3a) being seamed to each other by the flap 9 or 9a to provide a tube comprising the four panels. The plies 7 and 8 or 7a and 8a constitute two end-wall-forming panels each hinged at a iirst edge to its own one of an adjacent pair (1, 2 or 1a, 2a) of the four tube panels 1-4 or 1a-4a. The plies 5 and 6 or 5a and 6a constitute liner panels for forming the inner plies of two Walls of the container unit which two walls7 outer plies will comprise the tube panels 3, 4 or 3a, 4a. Each of the two end-wall-forming panels 7 and 8 or '7a and 8a is hinged at -a second edg-e opposite to its above-mentioned first edge to one of the liner panels 5 and 6 or 5a and 6a. The width of each of the end-wall-orming panels between its above-mentioned iirst and second edges is suihcient to allow the hinged edge of its associated liner panels 5 `and 6 or 5a and 6a to snugly engage the inner side of the tube at an end thereof when the tube is erected, but such width is insuflicient to allow the lastmentioned hinged edge to extend over the end of the tube. i

vThe blanks shown in IPGURE 7 may also be made up into boxes or units embodying some or all aspects of the invention. The outer or cover box blank includes the plies or panels 11-18 and the ap 19. The inner box includes the plies or panels 11a-18a and the ap 19a. The blanks are made up into boxes by fastening the tabs 19 and 19a to the panels 13 and 12a, respectively, and folding the blanks as indicated. The boxes are assembled into a container having triple ply side walls and double ply end walls. A yfirst side wall may comprise the plies 12, 13a, 15a, the plies being stated in the order of their disposition form outer to inner locations in the structure. A second adjacent side wall may comprise the plies 13, 12a, 16a. A third side walls adjacent to the second and opposite the rst may comprise the plies 14, 15, 11a. The fourth side wall may comprise the plies 11, 16, 14a. The upper end wall comprises the outer ply 17 and the inner ply 1S. The lower end wall comprises the outer ply 18a and the inner ply 17a.

The cover box or cover unit in this resulting container is vertically elongated and has adjacent, upright, single ply walls 12 and 13. The other Walls of the box are adjacent, double ply walls having outer plies 11 and 14 and inner plies 16 and 15, respectively. The plies 11 and 14 yare hinged to and integral with each other and also each is hinged to and integral with another ply (12 and 13 respectively) of another of the side walls (the single ply walls 12 and 13, respectively). The side walls will therefore be seen to comprise four rectilinearly disposed walls with a pair of the side walls being double ply, the remaining pair of the side walls being single ply, and each member of each of such pairs being adjacent to the other member of its pair.

The end wall of the cover box, made up from the panels 1li-18, comprises an outer ply 17 and an inner ply 18. Each of the plies "17 and 18 is hinged to and integral with one ply on each of a twosome of opposite side walls. Thus, lthe ply 17 is hinged to and integral with the inner ply of the double ply side Wall 14, 15 and also is hinged to and integral with the single ply side wall 12. .The ply 13 is hinged to and integral with the inner ply 16 of the double ply side wall '11, 16 and also is hinged to and integral with the single ply side Wall 13.

The inner box or unit made up from the panels 11a-18a is vertically elongated and has adjacent, upright, single ply IWalls 11a and 14a. The othery Walls of this box are adjacent, double ply walls havinor outer plies 12a and 13a and inner plies 16a and 15a, respectively. The plies 11a and 14a are hinged to and integral with each other and also each is hinged to and integral with another ply (12a and 13a respectively) of. another of the side Walls (12a, 16a and 13a, 15a respectively). The side Walls will therefore be seen to comprise four rectilinearly disposed walls with `a pair of the side Walls being double ply, the remaining pair of the side Walls being single ply, and each member of each of such pairs being adjacent to the other member of its pair.

The end wall of the inner box or unit made up from the panels 11a-13a comprises an inner ply 17a and an outer ply 18a. Each of the plies 17a and 18a is hinged to and integral with one ply on each of a twosome of opposite side walls. Thus, the ply 17a is hinged to and integral with the inner ply 15a of the double ply side lwall 13a, 15a and also is hinged to and integral with the single ply side wall 11a. The ply 18a is hinged to and integral with the inner ply 16a of the double ply side wall 12a, 16a and also is hinged to and integral with the single ply side wall 14a.

The width of the plies 17, 18, 17a and 18a between their bounding hinge lines is such as to cause the plies 15, 16, 15a and 16a respectively, in the erected condition of the structure, to be positioned immediately and snugly adjacent the inner sides of the plies 14, 11, 13a and 12a respectively. The transverse Width of the plies 15, 16, 15a and 16a is preferably such as to cause the side edges of these plies to snugly engage the plies or walls against which these edges abut, in lthe erected condition of the carton.

The cover box or unit 11-18 and the inner box or unit 11a-18a may be collapsed, shipped and erected in the ways previously described in connection with the boxes 1-8 and 1ila-8a.

Referring to *FIGURES 1l-l6 of the accompanying drawings, the container other illustrated is not a cornposite container consisting of an inner box and an outer box, but rather comprises only one box, which is adapted to be combined with a suitable liner.

Since in connection with the container shown in FIG- URES 11-16 there is no cover box or inner box, as such, the reference character ai is not used in connection with these figures to show correspondence of parts, as was done in connection with FIGURES 1-10.

The box shown in FIGURES 11-16 is preferably squat rather than elongated. yIt has adjacent, upright, single ply side walls 21 and 22. The other walls of the box are double ply, having outer plies 23 and 24 and inner plies 25 and 26, respectively. Single plies 21 and 24 of two adjacent side walls (21 and 24, 26 respectively) are hinged to and integral with each other and also each is hinged to and integral with another ply (22 and 23 respectively) of another of the side walls (22 and 23, 25 respectively). The side walls will therefore be seen to comprise four rectilinearly disposed walls with a pair of the side Walls lbeing double ply walls and the remaining pair of the side walls being single ply walls, and each member of each ofsuch pairs being adjacent to the other member of its pair. j

An end wall of the article comprises an inner ply 27 and an outer ply 28. Each of the plies 27 and 28 is hinged to and integral with one ply of each of a twosome of opposite side walls. Thus, the ply 27 is hinged to and integral with the inner ply 25 of the double ply side wall 23, 25 and also is hinged to and integral with the single ply side wall 21. The ply 28 is hinged to and integral with the inner ply 26 of the double ply side Wall 24, 26 and also is hinged to and integral with the single ply side wall 22.

At the other end of the article, llaps 20 are integrally hinged to the plies or panels 21-24. Theaps`20 are glued or otherwise suitably adhered or fastened to form an end wall opposite to that formed by the plies or panels 27 and 28. These aps 20 must be unfastened to conveniently collapse the box.

The plies 22 and 23 are joined by a seam or flap 29 Which is integral with the ply 22 and is suitably fastened to the ply 23 by stapling or by gluing or by other suitable means.

The container unit thus far described is preferably augmented by a supplemental liner, Such as the supplemental liner t) shown in FIGURE 24 or the supplemental liner 51 shown in FIGURE 25. In FIGURES 12-15, the article is shown provided with the supplemental liner 50. The use of the supplemental liner 5t) provides a total of three plies of paperboard on each side of the assembled article. The use of the supplemental liner 51 provides a total of two plies of paperboard on each side of the assembled article. It will be seen that whichever supplemental liner is used, the number of plies of the supplemental liner at the single ply side walls formed by the plies or panels 21 and 22 exceeds by one the number of plies of the supplemental liner at the double ply side walls 23, 25 and 24, 26.

The width of the plies 27 and 28 between their bounding hinge lines is such as to cause the plies 25 and 26, respectively, in the erected condition of the structure, to be positioned immediately and snugly adjacent the inner sides of the plies 23 and 24, respectively. The transverse Width of the plies 25 and 26 is preferably such as to cause the side edges of these plies to snugly engage the plies or walls against which these edges abut in the erected condition of the carton.

The article may be shipped in the collapsed position shown in FIGURE A. It may be erected by the end user by following the sequence of steps shown in FIG- URES 15B to 15H, except that the end flaps 20 need not be folded outwardly as shown in FIGURES 15B to 15H. They are so shown in the drawings to enable the other parts to be more clearly seen. The article may be shipped in a different collapsed state by extending the two long liaps, one of which consists of the members 25 and 27 and the other of which consists of the members 26 and 28, from :the opposite or rear end of the article, as it is seen in FIGURE 15. However, the article is less conveniently erected from this latter collapsed condition. In any event, the arrangement is such that the inner ply 25 or 26 of each double ply side wall of the article may, with its associated end wall ply, be collapsed inwardly when the article is empty and the end -aps are open. However, a

this may not be done when the end aps 20 are closed. In use, there will rarely be occasion to collapse the structure, but the structural features which render the structure so collapsible also render it readily erectable, and this latter feature is of signicance, as earlier explained.

-It should be clear that for the article shown in FIG- URES lil-l5, the plies 21-24 constitute four adjacent rectilinear tube-forming panels, the two laterally extreme panels of the four (22 and 23) being seamed to each other by the ap 29 to provide a tube comprising the four panels. The plies 27 and 28 constitute two end-wall- Iforming panels each hinged at a first edge to its own one of an adjacent pair (21, 22) of the four tube panels 21-24. The plies 25 and 26 constitute liner panels for forming the inner plies of two walls of the unlined article which two walls outer plies will comprise the tube panels 23 and 24. Each of the two end-wall-forming panels 27 and 28 is hinged at a second edge opposite to its above-mentioned n'ii'st edge to one of the liner panels 25 and 26. The width of each of the end-wall-forming panels between its abovementioned -irst and second edges is su'icient to allow the hinged edge of its associated liner panels 25 and 26 to snugly engage the inner side of the tube at an end thereof whenthe tube is erected, but such width is insufficient S to` allow the last-mentioned hinged edge to yextend over the end of the tube.

The blank shown in the left hand portion in F'IGURE 17 may also be made up into an article embodying some or all aspects of the invention. A container employing this article is shown in FIGURES 18-20.

With reference to these figures, the illustrated container again comprises only one box which is adapted to be combined with a suitable supplemental liner.

The box shown in FIGURES 18-20 has adjacent, upright, single ply side walls 31 and 34. The other walls of the box are double ply, having outer plies 32 and 33 and inner plies 36 and 35 respectively. Single plies 31 and 34 of two adjacent side walls (31 and 34) are hinged to and integral with each other and also each is hinged to and integral with another ply 32 and 33' respectively) of another of the side walls (32, 36 and 33, 35 respectively). The side walls are therefore seen to comprise four rectilinearly disposed walls with a pair of the side walls being double ply walls and the ramaining pair of the side walls being single ply walls, and each member of each of such pairs being adjacent to the other member of its pan.

An end wall of the article comprises an inner ply 37 yand an outer ply 38. Each of the plies 37 and 38 is hinged to and integral with one ply of each of a twosome of opposite side walls. Thus, the ply 37 is hinged to and integral with `the inner ply 35 of the double ply side wall 33, 35 and yalso is hinged to and integral with the single ply side wall 31. The ply 38 is hinged to and integral with the inner ply 36 of the double ply side wall 32, 36 and also is hinged to and integral with the single ply side wall 34.

At the other end of the article, aps 3G are integrally hinged to the plies or panels 31-3-4. The flaps 30 are glued or otherwise suitably adhered or fastened to form an end wall opposite to that formed by the plies or panels 37 and 38. These flaps 3) must be unfastened to conveniently collapse the box.

The plies 32 and 33 are joined by a seam or iiap 39 which is integral with the ply 33 and is suitably fastened to the ply 32 by stapling or by gluing or by other suitable means.

The container unit thus far described is preferably augmented by a supplemental liner, such as the supplemental liner 50 shown in FIGURE 24 or `the supplemental liner 51 shown in FIGURE 25. In FIGURES 18-20, the article is shown provided with the supplemental liner 50. It will be seen that which ever supplemental liner is used the number of plies of the supplemental liner at the single ply side walls 31 and 34 exceeds by one the number of plies of the supplemental liner at the double ply side walls 32, 36 and 33, 35.

The width of the plies 37 and 38 between their bounding hinge lines is such as to cause the plies 35 and 36, respectively, in the erected condition of the structure, to be positioned immediately and snugly adjacent the inner sides of the plies 33 and 32 respectively. The transverse width of the plies 35 kand 36 is preferably such as to cause the side edges of these plies to snugly engage the plies or walls against which these edges abut in the erected condition of the carton.

It should be clear that for the article shown in FIG- URES 18-20, the plies 31-34 constitute four adjacent rectilinear tube-forming panels, the two laterally extreme panels of the four (32 and 35) being seamed to each other by the flap 39 to provide a tube comprising the four panels. The plies 37 and 38 constitute two end-wallforming panels, each hinged at a iirst edge to its own one of an adjacent pair (3l and 34) of the four tube panels 31-34. The plies 35 and 36 constitute liner panels for forming the inner plies of two walls of the unlined article which two walls outer plies will comprise the tube panels 33 and 32. Each of the two end-wall-forming panels 37 and 33 is hinged at a second edge opposite to 9 its above-mentioned first edge to one of lthe liner panels 35 and 36.

The box shown in FIGURES 18-20 may be collapsed, shipped and erected in the ways previously described in connection with the box illustrated in FIGURES ll-l6.

The blank shown in the right hand portion of FIGURE l7 may also ybe .made up into an article embodying some or all of the aspects of the invention. A container employing this article is shown in FIGURES 21-23.

With reference to these gures, the illustrated container again comprises only one box which is adapted to be combined with a suitable supplemental liner rather than consisting of an inner box and an outer box.

The box shown in EGURES 2l-23 has adjacent, upright, single ply side walls 42 and 43. The other walls of the box are double ply, having out-er plies 41 and `44 and inner plies 46 and 45 respectively. Single plies 4l and 44 of two adjacent side Walls (41, 46 and 44, 45) are hinged to and integral with each other and also each is hinged to and integral with another ply (42 and 43 respectively) of another one of the side walls (42 and 43 respectively). The side walls will therefore `be seen to constitute four rectilinearly disposed walls with a pair of side walls being double ply walls and the remaining pair of the side Walls being single ply walls and each member of'such pairs being adjacent to the other member of its pair.

An end wall of the article comprises an inner ply 43 and an outer ply 47. Each of the plies 4S and 47 is hinged to and integral with one ply or" each of a twosome of opposite side walls. Thus, the ply 4d is hinged to and integral with the inner ply 46 of the double ply side wall 4l, 46 and also is hinged to and integral with the single ply side wall 43. The ply 47 is hinged to and integral with the inner ply 45 of the double ply side wall 44, 45 and also is hinged to and integral with the single ply side wall 42.

At the other end of the article, flaps 4t) are integrally hinged to the plies or panel 41-44. The aps 4t) are glued or otherwise suitably adhered or fastened to form an end wall opposite to that formed by the plies or panels 47 and 48. These aps 40 must be unfastened to conveniently collapse the box.

The plies 42 and 43 are joined by a seam or ap 49 which is integral with the ply 43 and is suitably fastened to the ply 42 by stapling or by gluing or by other suitable means.

Again, the container unit thus far described in connection with FIGURES 21-23 is preferably augmented by a supplemental liner such as the supplemental liner i) shown in FEGUPLE 24 or the supplemental liner 51 shown in FIGURE 25. In FIGURES 2l-23 the article is shown provided with the supplemental liner 59. It will be seen that whichever supplemental liner is used, the number of plies of the supplemental liner at the single ply side Walls 42 and 43 exceeds by one the number of plies of the supplemental liner at the double ply side Walls 4l, 46 and 44, 45.

Again, the width of the plies 47 and 4S between their bounding hinge lines is such as to cause the plies 45 and 46, respectively, in the erected condition of the structure, to be positioned immediately and snugly adjacent the inner sides of the plies 44 and 41, respectively, and the transverse width of the plies 45 and 46 is preferably such as to cause the side edges of these plies to snugly engage the plies or walls against which these edges abut in the erected condition of the struc-ture.

It should be clear that for the article shown in FIG- URES 21-23, the plies 41-44 constitute four adjacent rectilinear tube-forming panels, the two laterally extreme panels of the four (42 and 43) being seamed to each other by the hap 4% to provide a tube comprising the four panels. The plies 47 and 48 constitute two end-wall-forming panels, each hinged at a iirst edge to its own one of an adjacent pair (42 and 43) of the four tube panels 41-44. The plies 4S and 46 constitute liner panels for forming l@ the inner plies of ltwo walls of the unlined article which two walls outer plies will comprise the tube panels 44 and 41. Each of the two end-wall-forming panels 47 and 48 is hinged at a second edge opposite to its above-mentioned rst edge to one of the liner panels 45 and 46.

The box shown in FIGURES 21-23 may be collapsed, shipped and erected in the ways previously described in connection with the box illustrated in FIGURES 11-16.

The structure shown in FIGURES 26-30 comprises an inner box or unit and a cover box or unit, the two boxes or units being preferably of shnilar construction except for the slight differences in dimensions necessary to permit the cover box to ht closely over the inner box.

Again as before, in order to distinguish the parts of the inner box from the parts of the cover box where the two are in assembled relation while at the sarne time showing the similarity between the two boxes, the parts of the inner box are designated with the same reference numerals as the corresponding parts of the cover box, with the addition of the reference character a.

The cover box or unit which is shown has adjacent, upright, single ply walls 6l (not seen in FIGURE 26) and 62. The other walls of the box are double ply walls having inner plies 63 and 64 and outer plies 65 and 66, respectively. Single plies (6l and 64) of two adjacent side Walls (6l and 64, 66) are hinged to and integral with each other and also each is hinged to and integral with another ply (62 and 63 respectively) of another of the side walls (62 and 63, 65 respectively). The side walls will therefore be seen to comprise four rectangularly disposed walls with a pair of the side walls being double ply, the remaining pair of the side Walls being single ply, and each member of each such pairs being adjacent to the other member of its pair.

The end wall of the cover box or unit comprises an inner ply 67 and an outer ply 63. Each of the plies 67 and 63 is hinged to and integral with one ply of each of a twosorne of opposite side walls. Thus, the ply 67 is hinged to and integral with the outer ply 65 of the double ply side wall 63, 65 and also is hinged to and integral with the single ply side wall 6l. The ply 63 is hinged to and integral with the outer ply 66 of the double ply side wall 64, 66 and also is hinged to and integral with the single ply side wall 62.

In the particular structure illustrated, the plies 62 and 63 are joined by a seam or flap which is integral with the ply 62 and is suitably fastened to the ply 63 by stapling, or by gluing or other suitable means. The plies 65 and 66 are atiixed to the plies 63 and 64, respectively, as by gluing or other suitable means.

The inner box or unit which is shown has adjacent, upright, single ply side walls 6in and 62a. The other Walls of the box are double ply, having inner plies 63a and 64a and outer plies 65a and 66a, respectively. Single plies 61a and 64a of two adjacent side Walls (61a and 64a, 66a respectively) are hinged to and integral with each other and also each is hinged to and integral with another ply (62a 'and 63a respectively) of another of the side walls (62a and 63a, 65a respectively). The side Walls will therefore be seen to comprise four rectangularly disposed walls with a pair of the side walls being double ply walls and the remaining pair of `the side walls being single ply walls, yand each member of each such pairs being adjacent to the other member of its pair.

The end wall of the inner box or unit comprises an inner ply 67a and an outer ply 65a. Each of the plies 67a and 63a is hinged to and integral with one ply of each of -a twosome of opposite side Walls. Thus, the ply 67a is hinged to `and integral with the outer ply 65a of the double ply side wall 63a, 65a and also is hinged to and integral with the single ply side Wall 61a. The ply 63a is hinged to and integral with the outer ply 66a of the double ply side wall 64a, 66a and also is hinged to and integral with the single ply side wall 62a.

The plies 62a and 63a are joined by a seam or llap 69a
