CONTAINER Filed July 17, 1946 INVENTOR QZ ZWM ATTORNEYS Patented Aug. 21, 1951 OFFICE CONTAINER Earl R. Blair, Chicago, Ill., assignor to American Can Company, New York, N. Y., a corporation of New Jersey Application July 17, 1946, Serial No. 684,150

2 Claims. (01. 220-42) The present invention relates to a container or can and has particular reference to a can equipped with an annular seat member carrying a sealing gasket for a closure member applied to the can.

An object of the invention is the provision of a can wherein an efficient seal is provided between a seat member on the can body and a closure member applied to the can, so as to overcome the difficulty of making a seal between the side seam of the body and the closure member.

Another object is the provision of such a can wherein the exposed raw edges of the seat member and the can body are sealed in and protected against contact with the contents of the can so that corrosion of these edges will be prevented.

Another object is the provision of such a can wherein the seat member may be made of strip stock for economy of material and construction.

Another object is the provision of such a can wherein full drainage of the contents of the can may be readily efiected.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings:

Figure 1 is a top plan view of a sealed can embodying the instant invention;

Fig. 2 is a top plan view of the can with its cover removed; and

Fig. 3 is an enlarged vertical sectional view of the sealed can shown in Fig. 1.

As a preferred embodiment of the instant invention the drawing illustrates a filled and sealed sheet metal can made of tin plate or the like material. The can includes a tubular body having a bottom closure member l2 secured thereto in any suitable manner, as for example by the well known double seam I3 shown in Fig. 3.

At the upper end of the can, the marginal edge portion of the body H is bent inwardly and upwardly forming a tapered wall section |5 which terminates adjacent a mouth or filling and dispensing opening It for contents I! packed in the can. The tapered wall section l5 blends smoothly into the side Wall of the body to facilitate full drainage of the contents from the can when these contents are of a liquid nature.

The upper end of the can is provided with an annular seat member 2| which surrounds the can body for a cover or top closure member 22. This seat member is formed with an outer annular depending convexly curved bead Wall 23 the lower edge of which terminates adjacent the tapered wall section l5 of the can body. The upper edge of the bead is substantiallyflush with the upper edge of the tapered wall section l5. This upper edge of the bead merges into an annular straight channel wall section 24 which extends downwardly and inwardly toward the tapered Wall section l5 of the body.

Adjacent the tapered wall section I5 the channel wall section 24 bends upwardly into an annular cooperating inner channel wall section 25 which extends up along and contiguous to the tapered wall section l5. At its upper edge, the inner channel wall section 25 is interfolded in a joint or seam 26 with an outwardly reversely turned flange or marginal edge portion 21 of the tapered wall section l5 of the body. The joint 26 unites the seat member 2| with the can body.

The two cooperating

channel wall sections

24, 25 set off a V-shaped annular channel 28 which carries an annular resilient gasket 29 made preferably of rubber, rubber compound, lining material or the like. This gasket extends above the top edge of the can body and serves as a seal for the cover 22. The gasket also seals in or encloses the raw edges of the body flange 21 and the seat member channel wall section 25 and thus protects these edges from contact with the contents of the can so that corrosion of these edges is prevented.

The cover 22 preferably is of the countersunk panel type and is formed with a countersunk bottom wall 3|. The bottom wall 3| is surrounded by an integral connecting upright wall section 32. At its upper edge the upright wall section merges into an annular flat horizontal seat flange 33 which terminates in a depending skirt 34. The lower edge of the skirt is formed with a smooth curl 35.

When the cover 22 is in place on the can, its bottom wall 3| and connecting upright wall section 32 is disposed within the mouth It of the can. It is preferable that the upright wall section 32 be a slightly loose fit in the mouth of the can. However, if desired this wall section may be a tight frictional fit against the upper edge of the tapered wall section l5. The flange 33 of the cover overlies the seat member 2| of the can and engages against the gasket 29, the gasket providing a tight seal between the cover and the can.

The depending cover skirt 34 extends down adjacent and slightly below the bead 23 of the seat member 2| and at several places around its periphery the curled edge, designated by the numeral 35, is bent or crimped inwardly under the bead 23 to hold the cover in place on the can. The drawing shows three such crimpedunder sections indicated by the numeral 36 although any number of such sections may be provided as desired. In some cases the cover may be provided with interrupted screw thread sections for engagement with looking lugs formed in the seat member bead 23 instead of the crimped sections 36 to hold the cover in place.

With the cover crimped on the can as shown in Fig. 3 it is readily removable to gain access to the contents l1 and may be easily snapped back onto the can when the contents are only partially removed. The cover may thus be used as a reclosure, the gasket 29 serving as a seal for the reclosure as well as for the initial seal for the can.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the steps of the process described and their order of accomplishment without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the process hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. A sheet metal container, comprising a tubular body having an end thereof inclined inwardly to provide a smooth tapered wall terminating in a reversely bent flange defining the dispensing opening of the container, a separate annular cover seat member surrounding said opening and having an inwardly and upwardly inclined inner wall engaging said tapered body wall and interfolded with said reversely bent body flange, said cover seat member having an outwardly and upwardly inclined outer wall formed integrally with its said inner wall to form an annular V-shaped gasket receiving channel therebetween, said outer seat wall merging into an annular downwardly and inwardly extending convexly curved bead wall terminating adjacent the container body wall beneath said channel, a cover seal-ing gasket disposed in said channel and enclosing the exposed edges of said interfolded body wall flange and inner seat member wall for protecting said edges against contact with the container contents, and a countersunk cover member disposed within said dispensing opening and having a seating flange in sealing engagement with said channel contained gasket, said cover flange terminating in a depending skirt engaging beneath the annular curved bead wall of said seat member to removably secure the cover in sealing position on the container.

2. A sheet metal container, comprising a tubular body having its upper open end inclined inwardly and terminating in a reversely bent flange defining the outermost dispensing opening of the container, a separate annular cover seat member surrounding said opening and having an upwardly and inwardly inclined inner wall engaging said inwardly inclined body wall and confined at its outer portion within said reversely bent body flange, said annular cover seat member further comprising an outwardly and upwardly inclined outer wall formed integrally with its said inner wall to form an annular gasket receiving channel therebetween, and a cover sealing gasket disposed in and substantially filling said channel to enclose the exposed edge of said reversely bent body wall flange for protecting said edge and also the terminal edge of said inwardly inclined seat member wall against contact with the container contents, said outwardly and upwardly inclined outer wall terminating in a reversely bent edge which is substantially in the plane of the upper edge of said reversely bent flange of said body.
