4 Claims.

The present invention relatesto containers which are particularly adapted for the packing of ice cream and other edible materials which are intended to be made up in individual packages be eaten directly from the container. One object of the invention is to provide a relatively liquid-tight container capable of being manufactured in complete form at the box plant so that the container may be set up by the user without requiring any special machinery or without use of fastening devices other than the partsof the container itself.

A further object of'the invention is to provide asimple and effective construction of container including retaining means for a cover adapted to engage with parts on the cover to hold the same securely in place when the cover is assembled with the container.

A further Bbject is to provide a container of the type above described which will be extremely simple in form and easy to set up and use and which will be 'efiective for the pu pose intended.

To these and other ends the invention resides in certain improvements and-combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

, In the drawings:

Fig. 1 is a perspective view of one form of the container set up with the cover in place;

Fig. 2 is a fragmentary detail showing the manner of retaining the cover on the container;

Fig. 3 is a fragmentary perspective view of the parts shown in Fig. 2;

Fig. 4 is a view of the blank of the body portion of the container;

Fig. 5 is a view of the closure blank;

Fig. 6 is a perspective view of a modified form of container; v

Fig. '7is a fragmentary detail view, similar to Fig. 2, showing the manner of retaining the cover on the container;

Fig. 8 is a view of the blank of the body portion of the container; and

Fig. 9 is a view of the closure bank similar to Fig. 5. v

, The container of the present invention, as herein disclosed,'comprises a tapered tray portion or container proper and a cover portion adapted to be retained in place on the container so as to be secure from accidental displacement. Referring more particularly to the drawings,

. the container proper designated at l comprises abottom 2,side'walls3 and landendwallsi and 6 which are preferably formed with out I wardly tapered edges. The side walls 3 and l are provided respectively at their ends with flaps 3a., 3b and 4a, 4b. These flaps are formed with conventional interlocking portions which engage with each other to retain the container in as- 5 sembled or set-up condition, see particularly Fig. l l. The

end walls

5 and 6 are, in thepresent instance, first folded inwardly in assembling the container so that they will lie inside of the assembled interlocking flaps 3a, 6a; and 3b, 41). Due 10 to the construction just described it is apparent that the container may be set up and retained in condition to effectively hold the material. Other conventional means could, if desired, be employed to retain the side walls in container 15 forming position. I I

The cover for the container preferably comprises a closure panel I having side extensions 8,

- 8 and

end extensions

9, 9 alldeflned from the closure panel by the score lines indicated. By 20 folding inwardly the side and end extensions 8,

9, and 9, 9 it will be observed that a'recessed closure is formed which will flt within the top of the container l with the upper edges of the extension lying substantially flush with the .upper edges of the side walls of the container. The

extensions are preferably flared toward their outer ends so that when they are bent upwardly the sides of the cover thus formed will substantially conform to the taper of the side walls of upwardly the projections ID will extend outward- 1y of the cover and will remain in substantially the same plane as theplane of the closure-pan.-

el 1. When

theextensions

9, 9 are thus bent upwardly an opening II will be provided in each extension within which can be retained the 5 ends of a spoon, if desired, in the manner shown in my copending application, Serial No.- 36,759, filed August 19, 1935. I

Retaining portions are provided on the con tainer I, which, in the present instance, are conveniently formed by providing extensions l2, I!

on the

walls

5 and 6, which extensions are adapted to be folded inwardly against the inner faces of the

side walls

5 and 6 and may, if desired, be

securedby means of adhesive. These extensions i2, I: thus form relatively narrow abutment members or retaining strips on the inner faces of the side walls 5 and 6: and the projections it, It on the cover are adapted to snap into place beneath the lower edge of these strips so as to retain the cover in place on the container. Itis to be understood that the overall length of the cover through the projections l0, I0 is substantially equal to the corresponding interior dimension of the container when the coverds in place thereon. Due to this relationship it is apparent that, when the cover is being inserted,

the projections it, It bear against the inner faces their original planecondition in which the

extensions

9, 9 on the cover will lie flat against the strips I2, i2 and the

extensions

8, 8 on the cover will lie flat against the

side walls

3 and 4, thus making a substantially liquid-tight container which is well suited for the packaging of frozen confections, such as ice cream.

Referring to the modified form of the invention illustrated in Figs. 6 to 9, inclusive. the body portion of the container comprises a bottom 22,

side walls

23, 24, 25 and 25 and the locking flaps 23a, 23b, 24a and 2412. These parts are similar to the corresponding parts illustrated in Figs. 1 to 5. Reinforcing strips 230 and 260, in this form of the invention, are provided respectively on

walls

23 and 28. These strips are designed to be folded inwardly and to be adhesively secured to the inner faces of their attached walls to thus give these walls a greater rigidity along their upper edges than theywould otherwise normally have.

Extensions

32, 22 are provided on the

walls

25 and 26, each of these extensions being somewhat U-shaped toprovide additional tab-like extended portions 32a, 32a at the extremities of the extensions 82. The free edge 32c of the central portion of the flaps 32 will perform the same function as the free edge of strip l2 in the form of the invention shown in Figs. 1 to.5, namely, to retain the cover from upward displacement.

The extended portions 32a, 32a serve to reinforce the container adjacent its corners and permit the container to be made from lighter stock

ing side extensions

28, 28 and

end extensions

25 and 29, the cover being also formed to include

projections

30, 30, all of which features are substantially the same as the features illustrated would be required in the event these reinforcing portionsare dispensed with.

In the use of the modified form of the con tainer, the

extensions

32, 32 will be folded in- 0 wardly against their respective attached

walls

25 and 26 and will preferably be secured in place by suitable adhesive. container will be secured thereto as in the previously described form merely by forcing the cover within the top part of the container so that the The cover portion of the

projections

28, 30 on the cover engage beneath 'the edges 32c, 32c.

From the foregoing description it is apparent that a convenient and eifective form of container for edible materials is provided which can be packed flat for shipment to the user and by him readily set up and assembled without requiring special equipment. Due to the use of the inturned strips under the edges of which the projections on the cover are adapted to interlock, an efiective means for retaining the cover is provided without the use of an opening through the side walls.- The elimination of such an opening in the side walls prevents the loss of contents and insures maximum cleanliness .and freedom from contamination. These features, together with the feature of simplification of construction whereby the cover for the container may be readily assembled and removed, make the present container very desirable from both a sanitary and operations standpoint.

While the present description setsvforth a preferred embodiment of the invention, certain changes may be made in the construction without departing from the spirit of the invention, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being bad to the appended claims rather than to the foregoing description to indicate the scope of the invention.

I claim:
