James E. Whitley, Richmond, Calif., assignor to Mabelle L. Dier, West Vancouver, British Columbia, Canada Application June so, 1943, Serial No. 36,065 i 1 f i This invention. relates to new. and useful improvements in containers andthe primaryobject of thepresent invention is to, provide acollapsible 'box'or container for pie, cakeor other such food.-

stuff which will retain the article placed therein fresh and sanitary.

Another important object of the present invention is to provide a collapsible container in the form of .a triangleor a segment of a cylinder including a hinged cover or upper wall that embodies novel and improved means for retaining the container in assembled position and the up per wall in a closed and locked position.

A further-object of the present invention is to provide a collapsible box or container that is conveniently formed from a singleblank of material which may be pasteboard or cardboard when the same is discarded after use or of light weight metal or plastic when the same isto be reused. A still further aim of the present invention is to provide a collapsible container for sections of a pie or the like that is simple and practical in construction, small and compact in structure, strong and reliable in use, neat and attractive in appearance, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a plan view of the blank that is used to form the present container;

Figure 2 is a fragmentary perspective view of .the forward end of the present container in assembled position;

Figure 3 is a perspective view of the container constructed in accordance with the present invention, and showing the same in position for in for the purpose of illustration, there is disclosedea preferred embodiment of the presentinvention, the; numeral ll) represents generallye blank of suitable-material such .ascardboard, pasteboard, plastic or metal from which the present container is constructed. a

The blank-l0 includes a substantially triangular bottom wall I2 having an'arcuate end edge 14 and a pair of forwardly converging side edges 16 and, I8 that meet and are joined as at 20. These edges. [4, I16 and [8- are shown as section lines as they represent fold lines which will later become more fully apparent. Integrally formed with the arcuate edge 14 of the bottom wall, I2, is an arcuate end wall or rear wall 22 having an arcuate outer edge and transverse edges 26: and 28 that align the side edges I6 and [8 respectively.

The numera1s30 and 32. represent a. pair of substantially. rectangular side walls which are integrally formedwiththe side edges [6 and [-8 of the bottom wall-l2. The rear inner corners of these side. wallssare cut-off or removed to provide

inclinediedges

34 and 36.

A substantially triangular upper wall 38? is provided with a pair of forwardly converging

side edges

40 and 42, one of which, 40, is integrally formed with the side wall 32 and the remaining of which, namely, edge 42 is integrally formed with a retainer strip 44 that terminates adjacent the arcuate rear edge 46 of the upper wall 38 that lies in the same arcuate plane with the rear arcuate edge 24 of the rear wall 22.

Projecting forwardly from the forward transverse edge 48 of the side wall 30, is a substantially rectangular tab or forward end wall 50 which will bear against the inner face of the side wall 32 when the container is assembled.

Integrally formed with the outer free longitudinal edge 52 of the strip 44, intermediate the ends thereof, is a substantially rectangular tongue or holding flap 54 that slidably engages a loop 56 provided between a pair of spaced parallel slits 58 formed in the central portion of the side wall 30 when the present container is assembled, as shown best in Figure 2 of the drawings.

In forming the container 60, shown in Figure 3, the rear wall 22 is folded upwardly at an inclined angle along line or edge [4 and

side walls

30 and 32 are folded upwardly along lines or

edges

16 and 18 so that the

edges

34 and 36 of the

side walls

30 and 32 abut the

edges

26 and 28 of the rear wall 22. If desired, the

edges

34 and 36 are then suitably secured, by adhesive strips, glue or the like. to the

edges

26 and 28.

Next, the forward wall 50 is folded inwardly along line or edge 48 to bear against the inner face of the side wall 32 and may be, if desired, suitably fixed thereto by glue or other such means.

Then, the upper wall or closure 38 is folded downwardly along line or edge 4ll so that its arcuate edge 46 abuts and bears upon the arcuate edge 24 of the rear wall 22 and its side edge 42 abuts and bears upon the free outer edge 62 of i the side wall 32. 1

Finally, the retainer strip 44 is foldeddownwardly along edge or line 42 to bear against the outer face of the side wall 30 and the tongue 54 is slipped through the slits 56 to engage the loop 56 thus holding the container in its assembled position. V

Reference is now directed to Figure 7, wherein there is disclosed the present container in slightly modified form. In this embodiment, the container or box is constructed fromthe single blank of material shown in Figure 1, however, the walls are separated by cutting along the edges or lines IB, I8, 40 and 42, and the edges l6 and I8 of the bottom wall l2 are hinged as at 64 and 66 to the

side walls

30 and 32. Also, the upper wall 38 is hinged as at 68 and 10 to the side wall 32 and the retainer strip 44.

The tongue 12 integrally formed with the strip 44 engages a loop 14 struck outwardly from the side wall 30.

The end wall 50 is hinged to the side wall 30 or may be removed by providing an arcuate edge on either of the side walls which will overlap the remaining side wall.

Obviously, in this latest form the device is intended to be reused and may be conveniently cleaned or sterilized by collapsing the same.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

Having described the invention, what is claimed as new'is:

A collapsible container comprising a substantially triangular bottom wall having an arcuate end edge and a pair of converging side edges, an

arcuate end wall hinged to the arcuate end edge of said bottom wall, said end wall having first and second end edges aligned with the side edges of said bottom wall, first and second side walls hinged to the side edges of said bottom wall and having inclined rear edges adapted to abut the end edges of said arcuate end wall to retain the arcuate end wall inclined relative to said bottom wall, a substantially triangular upper wall having first and second sideedges and an arcuate end edge, the first side edge of said upper wall being hinged to said second sid wall, a flap hinged to the second side edge of said upper wall and adapted to overliea part of the first side wall, interlocking means between the flap and the first side wall, and a further end wall hinged to said first side Wall and adapted to bear against the inner surface of said second side wall.
