2 Claims.

This invention relates to cans and particularly to cans having a closure-receiving opening in one end which is adapted to be closed by a closure of the friction plug type, and one object of the invention is to provide a novel construction wherein the friction plug closure has a tab extending from the periphery thereof and permanently secured to the can, which tab functions as a hinge for the closure when the can is opened.

In order to give an understanding of the in vention I have illustrated in the drawing some selected embodiments thereof which will now be described after which the novel features will be pointed out in the appended claims.

1 In the drawing:

Fig. 1 is a sectional view through a can embodying my invention taken on the line I|, Fig. 2;

Fig. 2 is a top plan view of the can;

Fig. 3 is a view of the blank from which the closure is made;

Fig. 4 is a fragmentary sectional view-showing the closure plug removed from the closure-receiving opening;

Fig. 5 is a fragmentary sectional view showing a difierent embodiment of the invention;

Fig. 6 is a perspective view of the closure plug before it is attached to the can end.

The invention can be embodied in any can having a body portion and an end portion provided with a closure-receiving opening, and in Figs. 1, 2 and 3 I have illustrated the invention as it might be embodied in a can having an oval cross-sectional shape and provided with an ovalshaped closure-receiving opening. In the drawing l indicates the body portion of the can which has secured to one end thereof the closure-receiving end portion 2 which is formed with the opening 3 through which the can may be filled or through which the contents of the can may be removed or discharged.

The ring portion or closure-receiving end portion 2 may be secured to the can body in any of the ways now commonly employed for this purpose. As shown in the drawing this ring portion or closure-receiving end portion 2 is secured to the top edge of the body portion l by a double-lock seam 4. The ring or end portion 5 2 is formed with a depending skirt 5 which surrounds the opening 9 and provides a friction seating wall for the closure, which is indicated at 6. This closure 9 is of the friction plug type, it having the upstanding peripheral wall I which fits tightly within the depending skirt 5 thereby to make a tight joint, and if desired the upper edge 8 of the plug may be shaped to present a. bead as usual in closures of the friction plug type.

According to my present invention this closure 6 has a tab or extension 9 extending outwardly from the periphery thereof, which tab or extension is permanently secured to the can in some suitable way. The purpose of this tab or extension 9 is to provide a hinge connection between the plug and the can so that when the can is opened by prying the plug closure out of the opening 3 the tabor hinge portion 9 will flex thus permitting the closure to be swung backwardly into open position as shown in Fig. 4. r

One way of permanently attaching the extension or tab 9 to the can body is to roll the end portion of said tab into the double-lock seam 4 as shown in Fig. 1. Where this construction is used the tab 9 is permanently connected to the can by the operation of forming the double-lock seam 4. It will be understood, of course, that when the can body and the can end are assembled for the seaming operation, the can end 2 will have the closure plug fitted within its opening 3 and with the tab 9 extending outwardly from the periphery of the closure and into position to be acted on by the seaming rolls as the seam 4 is formed.

Instead of connecting the closure to the can by rolling the tab into the seam as above described, the permanent attachment between the tab and the can can be secured by spot-welding the tab to the ring 2. This construction is shown in Fig. 5 in which the can body is indicated at H, and said can body has the ring or 35 closure-receiving end portion l2 secured thereto and provided with the closure-receiving opening l3. In this embodiment the opening I3 is situated near one side of the can and the friction plug I4 by which the opening is closed has a 0 tab or extension [9 integral therewith and extending outwardly from the periphery thereof, said tab or extension overlying the ring or closurereceiving end portion l2 and being spot-welded thereto or otherwise secured thereto as shown at 29.

I prefer to make the tab portion 9 or I9 of sufiicient length so that when the can is opened the flexure of the tab will be distributed over a considerable length thereof and the tab will not be subjected to any sharp bends.

In the illustrated embodiment of the invention the tab 9 is made integral with theclosure 6, said closure and tab being formed from a sheet metal blank, such as shown in Fig. 3 which has the body portion l and the tab extending from the periphery thereof. This body portion l is subjected to the action of forming dies by which it is pressed into its final shape.

While the invention can be embodied in cans of various shapes, yet it has special advantages when embodied in a can having an oval or elongated closure-receiving opening and closure therefor. Various kinds of food products are frequently packaged and sold to the consumer in cans having the oval-shaped opening. In the manipulation of a can having an oval-shaped closure which is not attached to the can for the purpose of opening the can, spooning out some of the contents thereof and closing the can again, it frequently happens that the closure will drop into the can especially when the can is nearly empty, and when this happens it is. very difficult to remove the closure from the can. This cannot happen, however, in a can embodying my invention. because the hinge portion 9 retains the closure on the outside of the can and prevents the closure from assuming a position in which an end thereof can enter the opening.

While one convenient way of making the closure is to form it with the tab integral therewith, yet the invention would not be departed from if the tab were permanently secured to the closure member in some other way than by having it integral therewith. The important feature ineludes providing a closure for the closure-receiving opening of the can, which closure has a tab extending therefrom that is permanently secured to the can and constitutes a hinge member for hingedly connecting the closure to the can.

I claim:

1. A can having a body portion, a closurereceiving portion secured to the body portion at one end thereof by a double-lock seam, said closure reoeiving portion having a closure-receiving opening and a closure of the friction plug type fitting said opening, said closure having integral therewith a tab projecting from the periphery thereof, the end of which tabis rolled into the double-lock seam whereby said tab functions as a hinge for the closure when it is removed from the opening.

2. A can having a body portion and a closurereceiving portion secured to the body portion at one end thereof by a double-lock seam and provided with an opening, and a closure for closing said opening with a tight fit, said closure having integral therewith a flexible tab which extends from the periphery thereof and which overlies said closure-receiving portion, the end of said tab being rolled into the double-lock seam whereby when the closure is removed from the opening the tab flexes and constitutes a flexing hinge member for the closure.
