(Cl. ZBO-*60) 1 Claim. 1

This invention relates to friction cans or containers and has particular reference to a can embodying a pry-off plug cover having a curled periphery which is crimped beneath an annular edge of a friction ring secured to the can.

An object of the invention is the provision of an easy pry-off plug cover having a friction seat in the friction ring of a can and provided with a flange which terminates at its outer periphery in a curl, the curl being crimped beneath an edge of an outwardly and downwardly extended wall of the friction ring to further secure the cover in closed position.

Another object of the invention is the provision of such a pry-off cover having frictional engagement within the mouth of the container and having a flange shaped to fit upon a sloping wall of the friction ring, a curl formed in the periphery of the flange being engageable with and beneath a hemmed edge of the friction ring.

A further object of the invention is the provision in a can and cover of the character described, of a sealing gasket disposed between the fitted cover fiange and the friction ring wall for sealing the can, a curl formed on the outer periphery of the ange and engaged thereunder being disposed inside of and adjacent the can body and end seam so that a blunt tool may be inserted easily beneath the curl for removing the cover from its sealed position.

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 perspective view of a can embodying the present invention;

Fig. 2 is an enlarged fragmentary sectional view taken substantially along a plane indicated by the dot and dash lines 2-2 in Fig. i and showing a cover in sealed position, parts being broken away; and

Fig. 3 is a view similar to Fig. 2 showing the cover as it is being pried from the can.

As a preferred embodiment of the instant invention the drawings illustrate a can A with a pry-off cover B. The can includes a tubular body i1 having a side seam i2. A bottom end I3 is secured to the lower end of the body in an end seam I4. A friction ring I5 is secured to the upper end of the body in an end seam I6, these end seams being of conventional form.

The ring I5 includes an annular outer upstanding wall I1 which engages the interior of the body II at its upper end (Figs. 2 and 3) adjacent the end seam I6. vThe wall il merges into an inwardly and upwardly extending annulus I8. This annulus preferably slopes upwardly toward the opening in the can to better assist in a more complete removal of the can contents. At its inner end the annulus I8 merges into an upstanding friction wall 22 which forms the mouth of the can. This wall also provides a friction seat for the cover B.

At its upper end the wall 22 of the friction ring flares outwardly into a curved annular wall 23 and thence outwardly and downwardly into a surrounding flange 24. This flange terminates in an inwardly and reversely turned rim or edge 25. This edge is hemmed at 26, as shown in Figs. 2 and 3, this being a preferred form of the invention. The hemmed edge provides a suitable ledge beneath which a curl 2 of the cover may be engaged for closing the can.

The cover B includes a central panel 32 having an upstanding circular wall 33 which frictionally fits within the friction ring wall 22. The upper marginal portion of the wall 33 is formed or flares outwardly into a curved annular wall 34% which provides a groove or channel on the inside of the cover. This wall 34 substantially fits over the curved ring section 23 when the cover is in closed position. Wall 34 merges into a ange 35 which like the ring wall 24 extends outwardly and downwardly. Flange 35 preferably is formed to fit down over the annular ring wall 24 when the parts are in closed position. This flange terminates at its lower outer end in the curl 2l. The curl 21 is preferably rolled inwardly and is adapted to snap over the edge or rim 25 when the cover is applied to the can thus securing the cover in closed position.

The cover B may be hermetically sealed in closed position on the can and for this purpose a sealing gasket 36 is employed. This gasket is located in the annular groove on the inside of the curved wall 34 previously mentioned. Fig. 2 illustrates the hermetically sealed can and shows the cover B secured in place by engagement of the cover curl 21 beneath the friction ring edge 25.

The sealed cover B may be pried olf easily to open the can. This may be performed by means of a blunt tool such as a screw driver or the like. Fig. 3 shows the cover in a partially raised position as during its opening by a pry-off tool 38 which is fulcrumed on the surrounding end seam I6. The cover following the initial opening of the can may be used as a reclosure.

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 form, construction and arrangementI of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

A hermetically sealed pry-01T friction plug container comprising a tubular body having an annular countersunk friction ring secured to an end thereof in an end seam, said ring having an inwardly disposed upstanding annular friction wall dening the mouth of the container, the upper end of said ring wall flaring outwardly in a curved annular wall and thence into a downwardly and outwardly extending inclined ange terminating in a hemmed rim, a countersunk pry-01T plug cover for the container having an upstanding annular wall frictionally seated within said ring wall to close the mouth of the container, said cover wall flaring outwardly in a curved annular wall and thence into a downwardly and outwardly extending flange engaging against said friction ring flange and terminating in an inwardly extending curl having a snap engagement beneath the hemmed rim of said friction ring for removably securing the cover in closed position on the container, and an annular sealing gasket disposed between said outwardly curved annular cover and ring walls to hermetically seal the container, said cover being removable from the container by a prying engagement of the end of a tool beneath said cover curl and a fulcrum engagement of the tool on said container end seam.
