Patented Nov. 29, 1938 UNITED STATES PATENT OFFICE CARTON Application June 28, 1937, Serial No. 150,740

2 Claims.

Figure 1 is a plan view of the blank for making the carton, 18 Figure 2 is a top view of the closed carton,

Figure 3 is a top view of the carton with the upper closing flaps removed,

Figure 4 is a perspective view of a carton made from the blank shown in Figure l,

20 Figure 5 is an enlarged sectional view taken on line 55 of Figure 4.

Referring to the drawing, the tapered carton is formed from a single blank shown in Figure 1 made of cardboard or the like suitably scored 25 and folded. It comprises a bottom III, a front wall II hingedly connected to the bottom at its front edge, and a rear wall I2 hingedly connected to the bottom at its rear edge.

Hinged to each side edge of the rear wall I! 30 is an outer side panel I3 extending forwardly toward the front wall II, and hinged to each side edge of the front wall II is an inner side panel I4 extending rearwardly toward the rear wall I2 substantially along the inner surface of 5 the outer side panel I3. Side flaps I5 are hingedly connected to the side edges of the bottom II) and extend upwardly between the panels I3 and I l as shown in Figure 5, which are adhesively connected to each other in overlapping relation 40 and to the flaps I5.

For closing the top of the carton, closure means are provided, comprising a pair of inner flaps I8, one hingedly connected to the top edge of each side panel I3 and two outer or upper closure 45 flaps I8 and I1 hingedly connected respectively to the upper edges of the walls II and I2.

The inner flaps I8 are of the shape shown in Figures 1 and 3. The side edge 8 of the flap I8 forms a continuation of score line 5 but ex- 5 tends at a slight angle thereto as shown in Fi ure 1. The side edge I of flap I8 forms a con- "tinuation of the edge 8 of side wall I3 and extends at a slight angle thereto. The side edges 6 and I of flaps I8 are thus brought in from the 5 upwardly flaring relation of

vertical edges

5 and 8 of the outer side panels I3 to a strictly parallel relation. This construction of the flaps l8 makes it possible for the full length of the side edges 6 and I of the inner flaps to contact the full width of walls II and I2, when the flaps are folded 5 over in overlapping relation as shown in Figure 3 so as to abut the side walls and thereby prevent leakage or oozing of the contents in the carton. The upper closing flaps I6 and ll of the carton are adapted to be folded down over the inner 10 flaps I8. The flap I6 has a cut or slot 22 formed therein as shown in Figure 1. The other upper flap I1 is formed with a projecting tongue 28 which is slightly tapered, as shown in Figure 1, and which at its base is of approximately the same width as the length of the slit 22. The side edges 2 of the closure flap I! are cut inwardly as shown in Figure 1 so as to provide a substantial space between said edges and the opposing edges 6 of the inner flaps 18. When the cartons are cut out from the stock material the stock which is present between the flaps I1 and I8 can be readily removed as a result of this construction.

The construction above described is extremely advantageous and satisfactory for the purpose intended. The construction of flaps I8 is such as to provide a relatively tight closure at the top of the carton and effectively prevents the ice cream mixture or the like from leaking or oozing out. When the flaps I8 are brought into overlapped relation as shown in Figure 3 their side edges 8 and I contact or abut the full width of the walls II and I2 thereby completely sealing the contents and at the same time reinforcing the walls II and I2 so as to make them more rigid. Furthermore, as shown in Figure 4, flaps I8 form a continuation of side walls I3 which may be printed utilizing a single plate with a design P which extends slightly over on the flaps I8 at region 20. When the upper flaps I6 and I 'I are closed the area 20 is visible as shown in Figure 2. By extendingthe printed design P on the area 28 on flaps I8, the top of the carton will have a neat and finished appearance. These advantages are not present in cartons hitherto made as shown, for example, in Patent No. 1,950,934. In such cartons the flaps do not completely seal the contents.

While one embodiment of the invention has been disclosed, it is to be understood that the inventive idea may be carried out in a number of ways. This application is therefore not to be limited to the precise details described, but is intended to cover all variations and modifications 55 thereof falling within the spirit of the invention or the scope of the appended claims.

I claim:

1. A tapered receptacle formed from a single folded blank suitably scored to form a bottom, a front wall hingedly connected to said bottom, a rear wall hingedly connected to said bottom, inner side panels hinged to said front wall, outer side panels hingedly connected to said rear wall and arranged in overlapping relation to said inner side panels to form side walls of the receptacle, the vertical edges of said side panels being in upwardly flaring relation, inner closure flaps hinged to the said outer side panels, the side edges of said inner closure flaps being brought in from the upwardly flaring relation of the vertical edges of said outer side panels to a parallel relation, the full length of the side edges of said closure flaps being in abutting contact with the adjoining front and rear walls of the container, closure flaps hinged to the front and rear walls and adapted to be folded over and interlocked over the said inner closure flaps, the side edges of the closure flap hinged to the rear wall being cut away so a to provide a substam tial space between said edges and the opposin edges of the said inner closure flaps.

2. A tapered receptacle formed from a single folded blank suitably scored to form a bottom, a front wall hingedly connected to said bottom, a

rear wall hingedly connected to said bottom, in-

ner side panels hinged to said front wall, outer side panels hingedly connected to said rear wall and arranged in overlapping relation to said inner side panels to form side walls of the receptacle, the vertical edges of said side panels being in upwardly flaring relation, inner closure flaps hinged to the said outer side panels, said inner closure flaps being of sufiicient length to overlap at their free edges, the side edges of said inner closure flaps being brought in from the upwardly flaring relation of the vertical edges of said outer side panels to a parallel relation, the full length of the side edges of said closure flaps being in abutting contact with the adjoining front and I rear walls of the container, closure flaps hinged to the front and rear walls and adapted to be folded over and interlocked over the said inner closure flaps, the side edges of the closure flap hinged to the rear wall being cut away so as to provide a substantial space between said edges and the opposing .dges of the said inner closure flaps.
