1 Claim.

This invention relates to improvements in con? tainers adapted particularly for ice cream or the like and its purpose is to provide an improved r construction formed largely of paper or the like which may be made at a relatively small cost as compared with the metallic containers heretofore used for this purpose and which may be readily assembled and disassembled by the users thereof. The principal object of the invention is to provide a container having 'an annular wall formed of paper or the like in combination with improved means for uniting said wall with a bottom wall. A further object of the invention is to provide a collapsible container having improved means for detachably uniting an annular wall with a bottom wall so that the parts are held firmly in assembled relation with each other. A further object is to provide a container having an annular wall in combination with a bottom rim having a downwardly and outwardly flared annular portion adapted to receive a corresponding-' ly flared lower portion of the annular wall whereby the annular wall may be united with the bottom wall seated within the rim. Other objects relate to various features of construction and arrangement which will appear more fully hereinafter.

The nature of the invention will be understood from the following specification taken with the accompanying drawings, in which one embodiment is illustrated. In the drawings,

Fig. 1 shows a side elevation of the improved container embodying the features ofthe present invention;

Fig. 2 shows an enlarged side elevation of a portion of the lower edge of the container showing the tabs which are formed by longitudinally slitting the annular wall from the lower end thereof upwardly;

Fig. 3 is a detail vertical section on the line 33 of Fig. 1, showing the means for uniting the edges of the annular wall;

Fig. 4 is an enlarged horizontal section through the lower part of the container with parts broken away, illustrating the construction of the parts which permit the annular wall to be united with the annular rim and the bottom wall, the section being taken on the line 4-4 of Fig. 5; and

Fig. 5 is an enlarged side elevation of the lower portion of the container with a part thereof broken away and illustrated in vertical radial section.

The improved container 10 comprises an annular cylindrical wall 11 which is formed preferably of paper, cardboard or the like, the inner surface of which may be waxed or otherwise treated so that it is substantially waterproof. 'This wall is formed of a single sheet of paper or the like with the edges thereof overlapped and united with each other by means of staples 12. The wall 11 is provided with vertical indentations or fold lines 13 which may be formed preferably by compressing the paper or cardboard along these lines in order to permit it to fold readily. When this cylindrical wall has been formed, it may be collapsed into a flat shape for convenience in shipment and storage. This collapsed annular wall and the top and bottom walls, as well as the top and bottom rims of the tub, are shipped in disassembled relation and are assembled by the user of the container preliminary to filling it with ice cream or some other commodity. The present invention relates to the means by which this annular wall is united with the top and bottom walls.

For the. purpose of uniting the annular wall 11 with the bottom wall, the lower end of the wall 11 is provided with a plurality of longitudinal slits 14 forming intervening tabs 15 which are united along their lower edges with inwardly extending tapered tongues 16, as shown in Fig. 4. The tongues 16 are united by fold lines with the tabs 15 and the tongues are bent to extend radially inward before the bottom wall is applied. The tabs 15 and the tongues 16 are adapted to be seated within the lower rim 17 which is formed as an annular metallic member having a bottom flange 17 which extends radially inward and which is transversely corrugated as shown at 1'? to strengthen the construction and to permit the inward extension of the flange without buckling of the metal. The rim 17 further comprises an upwardly extending annular flange 1'7 which is provided with a series of transversely extending tapered corrugations 17 This rim 17 is preferably formed by the process described and claimed 0 in the United States patent to Messrs. Fork and Kronquest No. 1,771,955, dated July 29, 1930, whereby the flange 1'7 is caused to flare upwardly and inwardly from the lower flange 1-7 but this flare may be imparted by spinning or other means. The rim 17 is formed from a strip of sheet metal and when the flanges thereof have been corrugated and the proper shape imparted thereto by rolls or the like, the overlapping ends of the strap are welded or otherwise secured together to form the annular member illustrated in the drawings.

In assembling the annular wall 11 with respect to the annular rim 17, a circular bottom plate or wall section 18 is first seated upon the inwardly extending annular flange 17 asshown in Fig. 5,

and then the wall 11 which has been unfolded into cylindrical form is inserted within the annular flange 1'7 with the tongues 16 extending inwardly and resting upon the upper surface of the plate or wall section 18. The next step is to insert the circular bottom wall 19 which has a diameter slightly greater than the inner diameter of the annular wall 11 so that it has to be forced downwardly from the top under pressure, When the wall 19 reaches the bottom of the annular wall 11 it is forced outwardly into a position at right angles to the axis of the annular wall, as shown in Fig. 8, whereupon its outer edges engage the tabs 15 and force them outwardly so that they assume the flare of the annular flange 17 and coact with the inner surface of this flange throughout its depth. This outward flaring of the tabs 15 separates the slits 14, as shown in Fig. 5, and the bottom portion of the annular wall 11 is thus caused to have a wedging engagement with the annular rim 17 so that the rim and the annular wall are held in fixed relation to each other and at the same time the bottom wall 19, and the complementary bottom plate 18, are held in fixed position within the rim. The corrugations 1'7 not only assist in strengthening the flange 17 and permit the formation of a flare therein, but they also serve to increase the grip of the rim 17 on the lower part of the bottom wall. The container is then in readiness to receive a filling of ice cream or some other commodity to be stored or shipped therein, after which a cover is applied in the manner hereinafter described.

The cover 20 comprises a disk of cardboard or the like which is seated within an annular rib 21 formed on an annular metalic rim 21. This rim is adapted to surround the upper end of the annular wall 11 and to be secured to this annular wall by any suitable means such as that described in the co-pending application of Chester M. Mac- Chesney and Allen B. Wilson Serial No. 591,082, filed February 5, 1932. Of course, any suitable cover construction may be employed in conjunction with the improvements which are described above as constituting the present invention.

Although one form of the invention has been shown and described by way of illustration, it will be understood that it may be constructed in various other forms within the scope of the appended claim.

I claim:

The combination in a container, of a non-metallic annular wall having longitudinal slits in the lower portion thereof to form tabs capable of being bent outwardly, a plurality of tongues each united with one of said tabs and extending inwardly therefrom, an annular metallic rim having an annular flange transversely corrugated and extending inwardly beneath said tongues, said rim being further provided with'an annular flange provided with tapered transverse corrugations extending upwardly and inwardly around said tabs, a bottom plate seated upon said first-named flange of said rim beneath said tongues, and a bottom wall seated upon said tongues within said annular wall to force said tabs outwardly into wedging engagement with said second-named flange on said rim.
