' COLLAPSIBLE CONTAINER Application filed October 2,5, 192?. Serial No. 228,546.

This invention relates to collapsible containers.

One of the objects of this invention is the provision of an improved container which can be knocked down to permit packing and shipping in compact form, and which can be rapidlyset up for useinto a practically rigid, self-sustaining position.

A further object of this invention is to provide a container of the character set forth,

having an improved corner construction providing for interlocking the walls of the container in a particularly neat and efficient manner when in set up position, and serving also as a reenforcement for said walls, while at the same time permitting assembly of the box with maximum celerity and convenience. A further object of this invention is to provide a unitary blank for a container of the character set forth, of such design and construction as to make for a high degree of economy in labor and material in setting up the completed container therefrom.

Other objects of this invention Wlll in part be obvious and in part hereinafter pointed out.

The invention accordinglyconsists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application willibe indicated in the following claims.

1n the accompanying drawing, in which is .embodiments of this invention,

Fig. 1 is a plan view of a blank embodying the invention, indicating scored bend hues and cut-outs for a purpose hereinafter to appear.

Fig. 2 is a fragmentar corner of a container mem tion.

Fig. 3 is a fragmentary perspective view of said corner. v I

Fig. 4 is aperspective view of a container member made according to the invention.

Fig. 5 is a fragmentary perspective view of the blank for said container member, knock d down for shipment and ready to be plan view of a er in set up posishown one of the various possible illustrative folded to form the container of theinvention.

Referring in detail to the drawings,'B denotes a blank embodying the invention. Said blank is made of any suitable material, preferably a fibrous material, such as compressed paper board having the desired stiffness, and cut into a single piece, here shown as of rectangular form. Said blank may be provided with the longitudinal fold lines 10, and the transverse fold lines 12which may be scored upon blank B. These several lines define a body portion 13,.and end and

side sections

14 and 16, and the corner sections 18. Fold

lines

10 and 12 intersect at points 20, from which points fold lines 22 extend diagonally to the corners of blank B, dividing corner sections 18 into the

triangular sections

24, 26. A slit line 28 defines a tongue 30 cut in each section 24, the neck 32 of the tongue being on the portion 34 of the fold line 10 bounding corner section 18. A slit 36 is cut at a side of each triangular section 26 along the portion 33 of fold line 12 which forms a boundary for corner section 18.

In preparing the blank B for shipment to the point of use, or in preparing it for storage, it is desirable to set it up in such manner that the finished container may be swiftly developed from this intermediately prepared product. -F or these purposes,the blank B is folded inwardly on the lines 10, so that the corner sections 18 will lie on top of the end sections 14 while the side sections 16 will be superimposed along the sides of and upon the body portion 13. Rivets 40 may now be I driven through each end section 14 to secure thereto the superimposed trlangular section 24, the rivets being applied so as to engage that portion of the triangular section 24, not bounded by the slit line 28 and portion 34 of fold line 10; By this construction, there is provided an intermediate form F which lends itself readily. to shipment because of its inherent adaptability forassembly, hereinafter appearing.

When it is desired to set up a container C for use, a folded formF is used in the followingmanner. The end sections 14 and their secured triangular sections 24 are bent 'upwardly and inwardly of body portion 13.

to terminate in the tapered end portion 42,

Simultaneously side sections 16' will rise up wardly and bend outwardly from body portion 13, and triangular section 26 will be folded on line 22 into abutment with the face i of section 24, with slit 36 appearing in osition to receive the tongue 30 which has een sprung from triangular section 24 before the last bending operations were begun.

Said tongue,as apparent from the drawing, has a peculiar configuration for the purpose of facilitating the formation of container C and thereafter retaining the several parts thereof in fixed relation, and for resisting any undue strains thatmay be brought to bear upon said container. Tongue 30 is seen which extends from areduced body portion 44, the greatest width of which is less than the length of slit 36. The edges 46 of the tongue 30 at said body portion have the appearance of troughs. This effect is produced by a decided increase in the Width of tongue 30 as the edges 46 approach the neck of said tongue. Adjacent the neck of said tongue is a bulge 48 of slightly greater width than the length of said slit, while at the neck, I the tongue is reduced so as to be snugly received in said slit.

It can, therefore, be seen that, during the simultaneous

operationof bending sections

14, 16, 24 and 26 into their respective positions, the tapered end portion 42 may be inserted into slit 36 at each corner of container C, reduced, body portion 44 smoothly entering said slit until bulge 48 engages therewith. A slightly increased pressure on the outer face of end section 14 adjacent tongue 30 will serve to force bulge 48 through slit 3'6 and allow secure engagement between the reduced neck portion 32 of the tongue and said slit. It will be understood that a closed container may now be assembled, either by covering container C by a similar section, or by any other section of similar or different construction. In the drawing, however, for purposes of clarity, the cover section has been omitted. Y

By the herein described construction of container C, a reinforced corner construction for said container is provided without the use of any material other than that embodied in the single blank from which the container proper is formed. Furthermore, a container, readily set up from or collapsed into small, convenient compass for shipping and like purposes, is produced.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might made of the above-invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all'matterherein set forth or shown in the accompany ng drawing is to be interpreted as'1llustrat1ve and'not in a limiting sense.

Having thus described my invention, I

another edge of said corner portion to engage in said slit.

2. A container having end and side walls connected by corner portions, each corner portion being folded diagonally and lying against a wall of the box, a slit being formed at. an edge of the corner portion, and a tongue out so as to be folded from .another eiilge of said corner portion to engage in said s it.

3. A container having end and side Walls connected by corner portions, each corner portion being folded diagonally andlying inside of the box, a slit being formed-at an edge of said corner portion,.a tongue out out from said corner portion and folded on another edge of said portion to engage in said slit, and a permanentfastening means in proximity to said cut-out, securing one section only of said corner portion to the adjacent wall of the box.

4. A folding container having end and side walls connected by corner portions, each corner portion being diagonally folded and lying inside of the box, said corner portion having. a tongue foldable at one edge thereof and a slit in another edge thereof, said tongue being engaged in'said slit to hold adjacent side walls of said container together, and

permanent fastening means in proximity to said tongue for securing one folded section only of said corner portion to an adjacent wall of the box. A

5. A substantially rectangular one piece blank for making a container of the character described having fold lines marked thereon extending longitudinally and transversely of said blank, said lines defining a body, side and end walls for said container and integral corner portions, diagonal lines extending from the intersections of said longitudinal and transverse lines across said corner portionto adjacent corners of said blank,

and forming triangular sections, a tongue form slittedin one of said sections, and a single slit formed along a fold line between the other sections and an adjacent wall of the container. i v

In testimony whereof I afiix my signature.
