Application led May 5,

l Be it known that l', Hunt-:11T J. HicoiNs, a citizen of the United States, residing at Warwick in the count)Y ot' Kent and State ot lihode `island. have invented certain new and uset'ul Improvements in Foldable Containers, ot' which the following is a specification.

M v invention relates to toldable containers particularly adapted for cooking. baking and other shortening compounds.

The essential objects ot in v invention are convenience in packing and transport in av minimum of space: adaptability for application to triangular shaped contents; facility ot manipulation in application to and removal from contents; security against accidental disengagement: and simplicity and inexpensiveness of construction.

My invention consists` therefore, in the means for producing the results above specied substantially as hereinafter claimed.

In the accompanying drawings illustrating the principle of this invention and the best mode now known to me of applying that principle.

Figure 1 is a diagram of the blanklfrom which the container is constructed.

Figure 2, a perspective view of the blank partially formed,

Figure 3, a like view ofthe same at a later stage of completion,

Figure 4, a front perspective view of the container completely folded, and

Figures 5 and 6, sections of the same on lines 5-5 and 64-6 respectively of Figure 4.

Like characters of reference indicate like parts throughout the views.

The blank is cut from a sheet of paper or other bendable material. preferably o'l paper board. The blank 7, as shownjfin rear elevation in Figure 1, is substantially rectangular in general. outline and is provided near its bottom with a lateral. acute angular cavity 8, lateral cavity 9 comprising a horizontal straight outer portion 10 and an acute angular inner portion 11. The uppermost corner 14 of the tblank above the cavity, 9 is curved or rounded. The upper margin of the blank is cnt away from its edge inwardly to form an obtuse angular cavity 16, eccentric of the blank, and nearer the corner 14 than the opposite upper corner 17. The body is provided also with a diagonal slit or incision 19 continuous with one edge of the cavity 16, and with a second 1924. Serial No. 711,017.

slit 2O ot equal length and parallel to the tirst slit extending 'from one side ofthe cavity lt. The cavities 8 and 9 torni lateral cars or tlaps 22 and 23: the cavity 1G. cooperates therewith to i'orni two upwardly diverging wings 2l and 25; and the slits 19 and 2t) form a llap (3.

When the blank is composed ot' stiff niaterial it is scored for folding. Two of the folding lines n() and 31 extend. parallel with each other and diagonally from the terminals of the incisions to the cavitv 8. A. diagonal line extends troni the apex of the cavity 9 to the corner 1T ot the wing 24 and intersects the lines 30 and 31 at the terminals ot' the incisions. A second line 3G parallel with line 33 extends from the base of the acute angular portion of the cavity 9 to the cavitylG. A vertical line 37 extends from the end of the horizontal portion of the cavity 9 to the upper edge ot' the blank. A folding line 38 connects the apcxes of the cavities 3 and 9. and vertical lines 39 and 40 extend from said apexes to the lower'edge of the blank.

The lines 38, 39, and 40 bound the section 42constituting the bottom ot' the container; and lines 39 and 40 define the ends of the side tiaps 22 and 23. The :triangular section 43 bounded by the lines 30. 33 and 38 constitutes the front Wall of the box. Lines 30, 31. and 33 of the Wing Q4 bound the oblong diagonal section 44 constituting one side wall of the container. The triangular section of the Wing 24 bounded bv lines 3l and 33 constitutes the back 45 of the box. The slit 20 cooperates with the line 33 to form a foldable area 46 forming an inner section of the second side wall. which is adapted to retain the inturned flaps 26 and 23 which constitute an interior wall thickness. The oblong diagonal area 4T of the wing 25 bounded by the lines 33 and 36 constitutes an outer or overlapping portion of the second side Wall... Lines 36 and 37 bound the triangular area 48 of the wing 25 which overlaps the back Wall section 45 and constitutes an outer thickness thereof. The oblong laterally extending friction flap 49 upon the wing 25 having a square lower corner 5,0 will be hereinafter referred to.

In folding the container the blank rests with its back face uppermost` as shown in Figure 1, andthe triangular cake to be enclosed is laid thereon over the section 43 with which it peripherally registers, and

. constituting in .this instance the bottomv of' thereceptacle, is now elevated against the bottom of the cake, and the flap extensions 22 and 23 are bent against the sides of the cake. The wing 24 is now elevated and second side of the cake.

formed with the triangular front 43 parallel A front, a bottom integral with the front, an

brought towards they operator, and downwardly, and assumes. during this bendingy operation the position shown in Figure 2, the flap 26 being inwardly bent to be within the side wall 46 for engagement with the Thus the bod-v is with the back 45, and the inclined sides 44 and 46 converge at the apex of the container.

There is a resultant space or opening 51` between the bottom 42' and the adjacent edge of the back 45. The formation of thecon tainer is completed by bringing the wing up and over the body and inserting the friction binding member or flap 49 in the the corner 14 assists the entrance ofthe'second end into the opening.

It is evident that in folding the original 4blank 7 may initially be placed face down,

as herein shown, or face up, in which case the front of the folded receptacle in one instance would be the back of the`folded re- `ceptacle in the other instance, therefore, the

use of the words front or back in the claims will be read with such understanding.

' x I have entered into a detailed description of the construction and relative arrangementof the parts embraced in the present embodiment of my invention in order to 1mpart a full, clear, and exact understanding "ofthe same. I do not desire to be understood as confining myself to the specific con- 1 struction and relative arrangemen't'of parts shown as such changes or modiiications may l be made in practice as fairly fall within the scope of my invention as claimed.
