No. 610,550,

Figure 1 is an elevational view of a milk can filed May 11, 1932, issued August 15, 1933, as or the like constructed in accordance with the Patent 'No. 1,921,247, and reissued January 22,

This invention has to do with milk cans and has for its object to provide a milk can of imufacture of milk cans to provide a breast and body which overlapped, the overlapping portions being riveted together and the inner and outer surfaces of the cans tinned. This construction has been found unsatisfactory for the reason that the edges of the overlapping portions constitute Figure 2 is an enlarged fragmentary half sectional view taken approximately in the plane indicated'by the line II-II in Figure 1.

Referring now more particularly to the drawing, wherein the same parts are designated throughout by the same reference characters, the can i is preferably made mainly of sheet metal and includes among other things a breast 2, a body 3 and a base construction indicated generally at 4. The breast 2 has a substantially conical portion 5 and a cylindrical skirt 6, the latter having the same diameter as the body 3, but being spaced therefrom as shown in Figure 2. For the purpose of uniting the skirt 6 with the body 3,

there is provided a ring 1 having an internal I am aware that many changes may be mad and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I, therefore do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.

I claim as my invention:

1. A milk can construction comprising a breast portion having a cylindrical skirt, a cylindrical can body, means interposed between the lower edge of said skirt and the upper edge of said body to provide an abutment for said edges and to retain the inner surfaces of said skirt and of said body in alined relation and to provide a double wall for said skirt and for the upper portion of said can body, said means comprising a ring having an interior flat face disposed flush with the alined inner surfaces of said skirt and of said can body, and being provided with an integrally formed and upwardly extendingcylindrical extension and with an integrally formed and downwardly extending cylindrical extension, upper extension being positioned to envelop said skirt, and said lower extension being positioned to envelop an upper portion of said can body, said cylindrical extensions being welded about their free edges to said skirt and to said can body, respectively, said ring having an outwardly extending rib providing a bumper for the assembled structure.

2. A milk can construction comprising a breast portion having a cylindrical skirt, a cylindrical can body, joint forming means interposed between the lower edge of said skirt and the upper edge of said can body to provide an abutment for said edges and to retain the interior surface of said skirt in alined relation with the interior surface of said can body, said joint forming means said comprising a ring having an interior flat face disposed flush with the alined interior surfaces of said skirt and body, and being provided with integrally formed and oppositely directed cylindrical extensions engaging the outer surface of said skirt and of said can body, respectively, said cylindrical extensions being welded about their free ends tosaid skirt and can body, respectively, and a bumper adapted to protect the assembled breast portion and can body at the joint, said bumper comprising an enlarged and outwardly extending central portion of said ring.

3. A milk can comprising a cylindrical can body, a ring seated on the upper edge of said can body and having an interior fiat face disposed substantially flush with the interior surface of said can body, a breast portion for said can seated at'its lower edge on said ring, means retaining said breast, and said ring, and said can body in alined and assembled relation, said means comprising a pair of oppositely directed and integrally connected cylindrical extensions of said ring positioned in overlying engagement with the exterior surfaces of the lower end of said breast portion and of the upper end of said can body, respectively, said cylindrical extensions being welded at their free ends to said breast portion and to said can body, respectively, and bumper means adapted to protect the aforesaid parts in their assembled relation, said bumper means comprising an outwardly extending rib formed integral with said ring and positioned intermediate said extensions.
