This invention to improvements containers and it relates to that type of container in which an annular non-metallic wall and a nonmetaliic end wall' are united witheach other by.

5 means of an annular metallic rim and in which a rim is provided about the opposite end or the annular wall. Such containers are commonly employed for packing and shipping ice cream and other food products and it"is desirable to pro-.

10 vide the upper edge of the annular non-metallic wall of such a container with a protecting metallic rim'whichnot only reeniorces the non-metallicwall during the shipment of the container but also protects the edge of this wall against injury 15 during the subsequent operation of gradually re moving thecontents the container therefrom. The principal object of the present invention is to provide an improved container comprising an annular non-metallic wall provided-at one end o with an annular rim provided with complementary portions located on opposite sides of the annular wall and cooperating with each other to form an indentation in the wall whereby the rim is retained in place. 25 vention is to provide an improved container comprising an annular non-metallic wall provided at one end with an annular metallic rim having parts which embrace the edge oithe annular wall and having an annular groove in one 01' these 30 parts which is adapted to receive a portion 0! the annular wall which is projected into this groove by the edge of the other part so that an interlocking connection is formed between the annular wall and the rim. A further object at the in- 35 vention is to provide an improved method of forming a container according to which the annular non-metallic wall oi. a container is brought into engagement with a surrounding metallic rim having an outwardly projecting annular groove 40 and having an overhanging lip or flanga on the inner side or the container which is then projected outwardly so that the edge of this overhanging part projects a portion or the annular wall into engagement with the groove. Other vob- 45 :Ie ts of the invention relate to various features or construction and arrangement and to details or the method which will appear more fully hereinafter.

The nature of the invention will be understood 50 from the following specification taken with the accomp nying drawing, in which one embodiment of the invention and one example of the improved method are illustrated. In the draw- 18. u Fig.1isaperspectiveviewoitheimproved Another object of the in container of the present inventionwith a portion thereof brokenaway to illustrate the methodot uniting the annnuar wall withthe bottom wall of the container: I

Fig. 6 isa perspective view of a portion of the completed annular rim showing the formation of an annular bead or groove therein and an outwardly flared portion or the bottom of the rim and illustrating the curvature which is imparted 'to the rim during the process 01' forming the bead and the outwardly flared part.

As illustrated in Fig. 1, the container comprises an annular non-metallic wall II which may be formed by bending a sheet of flbreboard, cardboard or the like into cylindrical form and then uniting the overlapping edges thereof by 68-". menting them together or by employing staples or the like. This annular non-metallic wall is united with a bottom wall II, also preferably formed of a non-metallic material similar to that used in the construction of the wall ID, by means of an annular metallic rim l2 which is of angular cross-section, comprising a body portion I2 which surrounds the lower edge of the annular. wall i0 and an inwardly directed flange I! which underlies'and supports the bottom wall II. The overlapping ends of this rim are secured together by rivets II and the body portion I2 is provided with inwardly extending punched projections II? which extend into the material oi! the wall II to hold this wall in assembled relation with respect to the rim II. This construction and the method looking engagement with this wall. The rim II is adapted to be termed from an elongated strip ll' of sheet steel or the like, shown in l 'ig. 4,

ing the rim has its top portion curled inwardly bysuitable rolls or the like to form an inwardly and downwardly turned flange or lip I! which terminateain an angular part il= directed outwardly toward the body portion of the band, as shown in Fig. 5. The band having this overhanging lip or flange along its top edge is then operated upon by other mils to form an outwardly directed rib II in the body portion of the band opposite the extremity IF oi the lip or flange and to provide an outwardlyflared lower edge I? on the band. while at the same time imparting to it a curvature the curvature of the annular wall II to which it is to be applied. When the band or rim has been put into the form shown in Fig. 6, a section or this band of the required length is arranged with its ends overlapping and these ends are secured together by rivets II or the like, thus forming a complete annular metallic rim having an inwardly and downwardly extending flange or lip spaced from the body portion of the band, body portion oi this band has an internal diameter which corresponds with the outer diameter of the annular nonmetallic wall I! and the rim is then placed downwardly over the upper edge of the wall II, as illustrated inF'ig. 3, this action being facilitated by the action 01' the outwardly flared portion I 8' along the outer edge of the rim. when this has been done, the top edge portion of the container is rotated between rolls with the result that the applied pressure forces the flange or lip 'il outwardly and downwardly so that the body portion 0! this flange or lip lies parallel to the wall ll while the extremity li of the which corresponds to flange or lipiorcpsa portion II- o! the annular wall outwardly into lar groove II which is formed in the rim by the rib it, while at the same time forming an indentation I O" in the wall ll opposite this groove. An interlocking engagement is thus established which eflectually prevents the metallic rim II from being removed top edge of the annular wall as well as its inner and outer surfaces adjacent thereto, are thus protected by the complementary parts of the rim.

Although one form or the improved container and one example of the improved method of iorming it-havebeen shown and described by way 01' illustration, it will be understood that the invention may take various forms and that the method may be practiced in various ways, coming within the scope oi the appended claims.
