FOLDING LUNCH-BOX.

To all whom it may concern:

Be it known that I, JOHN F. LYoNs, a citizen of the United States, residing at'New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Folding Lunch-Boxes, of which the following is a specification.

My invention relates to improvements 1n folding lunch boxes and the objects of my improvement are simplicity and economy in construction and convenience and efficiency in use.

In the accompanying drawings :Figure 1 is a plan view of the blank from which my folding lunch box is made. Fig. 2 is a front view of the box in expanded condition and on an enlarged scale. Fig. 3 is an end view of the same. Fig. 4 is a sectional view on the line :20 w of Fig. 2. Fig. 5 is a similar view on the line y y of Fig. 3. Fig. 6 is an end view from the opposite end to that shown in Fig. 3, in part broken out, the cover being partially opened and the bottom with the inner end pieces folded thereon, tilted slightly upward. Fig. 7 is a longitudinal sectional view showing the box in collapsed condition on an enlarged scale. Fig. 8 is a sectional View on the line e 2 of Fig. 3, on the same scale as said Fig. 3. Fig. 9 is a reverse view of the section shown in Fig. 4. Fig. 10 is a side elevation of my box in partly collapsed condition.

A is the blank from which my folding lunch box is made and comprises an elongated, rectangular main body part B which Is divided by cross wise score lines 19 into a series of elements in longitudinal alinement which constitute the outside walls of my box and a securing flap 20 at one end and consisting of the said flap 20 at one end, the left end wall 21 at the other end and intermediate thereto the back wall 23, right end wall 24, and front wall 25. The said

end walls

21 and 24 are provided centrally with cross wise score lines 28 and which facilitate folding inwardly the said side walls. Rivet holes 35 are provided in the said front wall 25 for receiving rivets or other means for securing a clasp E suitable for fastening the cover to be described. The said flap 20 and left end wall 21 are Specification of Letters Patent.

Application filed December 13, 1912.

Patented June 23, 1914. Serial No. 736,528.

provided with rivet holes 22, shown as two in number in each, and which are suitable for receiving rivets, respectively an upper rivet C and a lower rivet D for securing the said flap and end wall. A rivet hole 22 is also provided in the back half 46 of the said right end wall 24 and near the lower end thereof. Integral with the top edge 26 of the said back wall 23 is the cover G, a score line along the said top edge 26 serving to determine the line on which the said cover will hinge in swinging back and forth relatively to the said back wall 23. Reinote from the said edge 26 the said cover is provided with an end flap 29, which hinges along the score line 30. End flaps 31, hinged along score lines 32 are provided along the ends of the said cover G, and which may have the corners 33 cut away. The said end flap 29 is provided with a hole 34 for an eye F, suitable for receiving the hook member 36 of the said clasp E. The said back wall 23 is provided along the lower edge 37 with a score line dividing off from the same a bottom reinforcing and supporting strip H, which has a strip body portion 38 of essentially the same length as the said back wall 23 and is preferably as shown of about one-half or less than one-half the width of the said bottom of the box tobe described, and is provided at the ends with strip and flaps, respectively the left end flap 39 and the right end flap 40, the same being limited by end score lines 47. Diagonal score lines 41 extending from the inner end corners 42 of the said strip H and across the same at an angle of about 45 degrees facilitate bending and folding the said strip H in collapsing my box. Rivet holes 22 are provided in the said

strip end flaps

39 and 40, the rivet holes 22 in the left end flap 39 registering in the folded condition of the blank with the hole 22 in the said flap 20 and left end wall 21 and the lower rivet hole 22 in the said right flap 46 registering with the rivet hole 22 in the said right end wall 24 andsuitable for receiving a rivet I. Integral with the bottom edge of the said front wall 25 and marked off from the same by a score line 48 is the bottom proper 49 constituting the central part of the bottom and end strip J, and having at each end and hinged to the said bottom proper 49 along cross-wise score lines 50 the left and right inner end and strap pieces, 51 and 52 respectively. The said

inner pieces

51 and 52 are of such length that the

top edges

54 and 64 of the same in the folded condition will be flush with the edge of the box generally so that in the expanded condition and with the cover closed the said top edges will be in contact with the under side of the said cover G. As shown in the blank A, the said right hand flap 40 of the bottom supporting strip H extends in the direction of the said bottom proper J beyond the left hand edge 54 of the said right hand inner end piece 52.

A pair of straps K have one end each secured by a rivet M to the outer side of one of the

inner end pieces

51 and 52 and their other ends joined by a buckle L, the point of attachment 55 of the same being such as to admit the said cover flap 31 between the said strap K and the said

end pieces

51 and 52 in the closed position and so that the lower edge of the said flap will be adjacent the said rivets M. In folding the said blank A to form my box the said

inner end pieces

51 and 52 are folded over inwardly against the said bottom proper 49 or at an angle of 90 degrees thereto and then the said main body B is bent upward along the score line 48 at right angles to the said bottom proper 49. Then the said main body part B is folded around the said bottom proper 49, being bent on the corner score lines 19 and with the end flap 20 overlapping the left end wall 21. The supporting strip H is then bent along the score line 37 and the

end flaps

39 and 40 thereof bent into position to be engaged by the said rivets D and I respectively, and secured by the said rivets, and the said rivet C inserted in the said upper rivet holes 22. The bottom proper 49 is then brought to rest on the bottom support H and the

end pieces

51 and 52 opened against the

end walls

21 and 24, thus completing the body of the box ready to receive material to be contained therein.

After the box is filled the cover is closed over the top, the side flaps 31 tucked in the sides, and the cover resting on the top edges of the said end pieces, the front flap 29 being brought against the front wall 25 and secured by the clasp or fastener E, and the straps K have their free ends secured by the buckle L. Vt hen arranged as described and lifted and supported by the said straps K the load on the bottom proper 49 is generally supported by the said

inner end pieces

51 and 52, secured to the said straps. W'hen, however, the box is lifted by the side walls, as may be convenient in the process of filling, the bottom proper 49 is supported in part by the said bottom supporting strip H which extends along the otherwise free and unsupported back end 56 of the same. The

front end of the said bottom proper 49 is supported by the said front wall 25, being integral therewith. The said rivet D it will be noted secures together three thicknesses of material consistingvof the flap 20, end wall 21 and flap 39.

In collapsing my box, the cover G is bent backward against the outside of the back wall 23, the side flaps 31 and end flap 29 turned inward; the

inner end pieces

51 and 52 are folded over the bottom proper 49, and the said bottom folded upward against the front Wall 25, access to the said bottom being,obtained through the opening 57 between the front edge 58 of the said bottom supporting strip H and the front bottom edge 48, and then the body of the box is collapsed by a bellows-like folding of the

end walls

21 and 24 and a similar folding of the said bottom supporting strip H along the said angular score lines 41. Accordingly my box has the bottom positively supported when in use, either by the end pieces or by the bottom supporting strip in coiiperation with the front wall; and the bottom supporting and reinforcing means is collapsible; and for collapsing the bottom is accessible from the outside; and my box is made from a single piece blank; and is held together positively by three rivets; and furthermore, the box as described cannot be shaped or formed so as to be in condition to receive or be filled with material or supplies without having the parts arranged as described and in a proper manner for use.

I claim as my invention:

1. A folding lunch box comprising end walls, a front wall, and a rear wall, the said walls being permanently connected together, the said end walls being collapsible along the middle portion, a bottom hinged by the front edge to the front wall and having the edge adjacent the said rear wall free, supporting means for the said free edge positioned be low the same in the open position and permanently connected to the said end walls, and having diagonal creases near the ends and the connecting means for so connecting the said supporting means and the end walls being so positioned relatively to the said end Walls as to permit the said supporting means to be collapsed simultaneously with the said end walls.

2. A folding lunch box formed of one sheet of material and having lateral walls and a bottom hinged by one edge to the front wall, and inner end pieces hinged to the said bottom, lifting straps secured to the said inner end pieces and thereby supporting said bottom when a lifting strain is applied to the said straps, means for sup porting the free edge of the said bottom independent of the said straps comprising a strip extending underneath the said free edge and secured to the end walls by securing means positioned on the said end Walls so as to permit the said box to be collapsed and expanded.

3. A folding lunch box formed of one sheet of material and having lateral Walls and a bottom hinged by the front edge to the front Wall, means for supporting the free edge of the said bottom comprising a strip extending below said bottom and secured to the end Walls, the said strip separated from 10 the said front edge by a space permitting of access to the said bottom for the purpose of swinging the same away from the said strip in collapsing the box.
