Claims.

My invention relates to improvements in collapsible containers for shipping or storage purposes.

- The invention is designed with the particular 5 purpose in view of providing an inexpensive,

light weight container comprising a pair of inner and outer sections, fitting together one within the other, to reinforce each other, each formed of a single piece of material," foldable into a collapsed, substantially flattened-out condition, and adapted for telescoping one within the other in their collapsed condition for shipment or storage as a collapsed unit.

My invention is furthermore designed to provide a container characterized as above set forth which is inexpensive to manufacture, strong and durable, and well adapted to protect the contents thereof against shocks and jars incident to shipping and handling.

To the accomplishment of the foregoing and other objects, presently appearing, a preferred embodiment of my invention has been illustrated in the accompanying drawings, and described and defined in the following description and claims, respectively.

In said drawings:

Figure 1 is a view in perspective illustrating m improved container with the sections fitted together. v

Figure 2 is a view in transverse section taken on the line 2--2 of Figure 1 looking in the direction indicated by the arrows.

Figure 3 is a similar view with the sections partly withdrawn one from the other.

Figure 4 is a .view in horizontal section.

Figure 5 is a' view in perspective of the inner section in collapsed condition, and

Figure 6 is a view in perspective illustrating the sections in collapsed and reversed telescoped condition for packing.

Referring to the drawings, the illustrated embodiment of my container comprises inner and outer sections l and 2, respectively, each formed of cellular board of the usual well-known type, the sections being of the proper dimensions to slidingly fit one within the other.

The inner section I is formed of a single piece of the material above designated cut, and folded upon itself, to form side walls 3, end walls 6,

cover wall 5 and a side flap l at one side edge of said wall ,5. The folds 8 at one end of the section I, between the side walls 3 and the end wall 2 provide integral hinge connections between said walls. The opposite end ,wall 2 is similarly cona cover wall 5, and flaps 6 at each end of the 1 1936, Serial No. 81,490

nected to one side wall 3 by the fold 9 therebetween and to the other sidewall by a strip of adhesive material I 0 forming a hinge at this point between said end wall and opposite side wall.- The cover wall 5 has an integral hinge connection to one side wall 3 by means of the fold ll therebetween. The folds l2 between the cover wall and theend flaps 6 form integral hinge connections therebetween whereby said flaps may be folded over the end walls 4 exteriorly thereof. The fold I3 between the cover wall 5 and the side flap l provides a similar connection for folding the flap against the outside of said side wall. The cover wall 5 is designed to be swung into closed position relative to the section I with the flaps 6 and l inserted between the walls of the inner and outer sections. To facilitate arranging the flaps 6 in the position their side edges it are preferably beveled. As will be obvious the primary purpose of the flaps 6 and I is to close the edges of the section.

To collapse the section I the cover wall 5, to-' gether with the flaps 6 and I are swung on the fold it until said cover wall is substantially aligned with its connected side wall 3. The other side wall 3 and the end walls t may then. be swung on the folds 8 and the strip ofadhesive material it! into a flattened-out position as shown in Figure 5. The flaps 6 and i may then be swung on the folds l2 and I3 outwardly of the connected side wall 5 into straightened-out position.

The outer section 2 is constructed in substantially the same manner as described with reference to the section l of a single piece of the same. material cut, and folded to provide side walls it, 'end walls it, a cover wall i1, an end flap l8 at each end of the cover wall El and a side flap H9 at one side of said cover wall. The folds 26 at one end of said section 2, between the end and side walls it and i5 form integral hinges between said end and side walls, and the other end wall it is similarly connected to one side wall it by an overlap 2i folded on said side wall as at 22. The cover wall ii is integrally hinged to one side wall It by a fold 23. The folds 2t and 25 between the cover wall Ill and the end and side flaps it and M, respectively, provide for folding said flaps in a position to fit within the section 2 as shown in Figure 3. As in the case of the section 6 the flaps l8 are preferably beveled at their sides as at 26 to facilitate swingingthem into the section 2.

As best shown in Figure 2 the flaps 6 and l and y it and it are designed so that'in thev closing 5 positions of the cover walls 5 and I! the flaps on one of'said walls almost engage the flaps on the other wall so that when the sections are fully nested said flaps form substantially continuous third walls intermediate the side walls on one side of the section and intermediate the end walls of said-sections at both ends of the latter. This third wall is designed to additionally protect the contents of the section from shocks and jars.

The outer section 2 may be collapsed in substantially the same manner as described with reference to the section I. Since the procedure for collapsing this section is largely a matter of repetition of the procedure described with reference to the section I, it is believed to be unnecessary todescribe the same in detail.

As will be clear the section 2 in its collapsed condition is of the proper size so that its flattened-out side and end walls I5 and i6 form an envelope open at its side edges into which the corresponding collapsed parts of the section i may be inserted, the cover section 5 and the flaps 6 and I of the section i lying flat against the cover wall I! and flaps I8 and iii of the section 2. In this position of the section they are compactly arranged and removably secured together for storage or shipment as a collapsed or knocked-down unit. Obviously the sections i and 2 may be separately collapsed and secured together as above described orthe side and end walls of the sections may be collapsed together while they are in nested relation.

If desired the inner section I may be provided with a transverse partition 26 having flaps 21 hinged to the ends thereof by folds 28 and cemented or glued to the side walls 3 of said inner section so that the partition may be folded flat intermediate said side walls as shown in Figure 5.

From the foregoing it will be seen that my invention comprises a sectional container the sections of which may be knocked down or folded into a flattened-out condition and secured together in such condition by nesting a part of one within 'a part of the other. Furthermore the container in its set-up condition is provided with top and bottom closure walls either of which may be used for access to the container and which in their closed position form reinforcing walls intermediate the inner and outer containers around substantially three sides of the container.

It is to be understood that the details described in the foregoing are illustrative of a preferred embodiment of my invention only, and that right is herein reserved to modifications of such details falling within the scope of the claims appended hereto.

What I claim is:

1. A container comprising, nesting sections tion between said sections to prevent the latter from collapsing, and the end and side walls of the sections being foldable while in nested relation when said cover walls are in opening position.

3. A container comprising, a pair of sections adapted to nest one within the other, said sections comprising a pair of cover walls hinged to said sections, respectively, in, opposed relation and provided with edge flaps adapted to be inserted between said sections to form in the closed position of said cover walls reinforcing walls intermediate the ends and one side of the sections, respectively.

4. A container comprising, a pair of sections adapted to nest one within the other, said sections having a pair of cover walls hinged to said sections, respectively, in opposed relation and provided with edge flaps adapted to be inserted between said sections to form in the closed position of said cover walls reinforcing walls intermediate the ends and one side of the sections,

respectively, said sections comprising end and side walls hinged together in each section for folding flat upon each other.

5. A container comprising, a pair of sections adapted to nest one within the other, said sections having a pair of cover walls hinged to said sections, respectively, in opposed relation and provided with edge flaps adapted to be inserted between said sections to form in the closed position of said cover walls reinforcing walls'intermediate the ends and one side of the sections, respectively, said sections comprising end and side walls hinged together in each section for folding flat upon each other with the folded walls of one section telescoped between the folded walls of they other section.
