Description:

The invention relates to new and useful improvements in sheet metal containers of the friction plug closure type.

An object of the invention is to provide a construction of container which enables containers of the same size to be stacked one on another in centered relation and held from lateral shifting movement of parts of one interengaging parts of another.

A further object of the invention is to provide a container of the above type wherein the bottom end of the container is seamed to the body wall and is so shaped as to provide an annular downwardly projecting portion which is adapted to engage the bead on the friction plug closure of the container on which it is stacked, whereby the end seams of the stacked containers are centered relative to each other and the containers held from lateral shifting movement one on another.

In the drawing which shows by way of illustration one embodiment of the inventionFigure 1 is a view in vertical section through a portion of a container embodying the improvements; Fig. 2 is an enlarged view in vertical section through a portion of two containers, one of which is stacked on the other, and Fig. 3 is a detail in plan of one of the containers as viewed from above.

The invention as illustrated is embodied in a sheet metal container which includes a body portion I preferably of cylindrical shape. The container top 2 is secured to the body wall I by an end seam 3 which is of the usual construction.

Said container top 2 has a central opening therethrough, and the edge portion of said container top is curled downwardly so as to provide an annular friction seat 4.

The container is closed by a friction plug closure which includes a vertical upstanding portion 6 dimensioned so as to tightly engage the friction seat 4 on the container top 2. The friction plug has a portion 7 which overlies the container top and this portion 7 is extended upwardly and thence curved inwardly and downwardly to form 4 an annular bead 8.

An advertising panel 9 of fiber board is placed on this portion 7 which forms the supporting ledge therefor and is held on said supporting ledge by the inwardly curved bead 8. This ad- 5 vertising panel only extends a short distance under the curled edge and can be easily removed therefrom by a knife blade or other suitable tool.

The advertising panel 9 forms a cover for the recess in the plug therebeneath, so that an ad- 5 vertising booklet, if desired, may be placed in the recess and held therein by the panel. The advertising panel is formed with a slit 10 which is U-shaped, and this forms a finger grip 11 which may be raised for removing the panel from the closure plug. This friction plug when seated is so dimensioned that the bead 8 extends above a plane containing the extreme upper portions of the end seams 3.

A bottom end 12 is secured to the body wall I by an end seam 13. This bottom end is provided with an annular downwardly projecting portion 14 which terminates just above a plane containing the extreme lower portions of the end seams 13.

The downwardly projecting portion 14 includes a substantially horizontal flat portion 15 and a curved wall 16 depending therefrom.

The containers constructed as above described are adapted to be stacked one on the other, and when so stacked, the flat portion 15 in the bottom wall of one container is directly above and may rest on the bead 8 of the closure plug of the underneath container. When so stacked, the end seams are centered relative to each other, that is, the bottom end seam 13 of one container is directly above the top end seam of the underneath container, as shown in Figure 3. The curved portion 16 extends downwardly along the outer curve of the bead 8 and will prevent the containers shifting laterally one on another. This enables the containers to be stacked so that end seams are centered relative to each other and they will be firmly held in this stacked relation.

It is obvious that minor changes in the details of construction and the shaping of the parts may be made without departing from the spirit of the invention as set forth in the appended claim.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is: A container adapted to be stacked with similar 4L containers of the same size comprising a body portion, a container top seamed thereto and having a central opening surrounded by a friction seat disposed below the plane of the upper edge of the end seam, a friction plug closure fitting the 5 friction seat and having an annular upstanding bead at the peripheral edge thereof which projects above the end seam when the plug is fully seated, said container having a bottom end seamed to the body portion and having an annular down0 wardly projecting portion spaced inwardly from the end seam and shaped and disposed so as to engage the bead on the friction plug of another container on which it is stacked whereby the end seams of the stacked containers are centered rela5 tive to each other and the containers held from laterally shifting engagement one on another.
