6 Claims.

The present invention relates to a sheet metal container or can adapted to be opened by the removal of a tearing strip which is formed in a wall of a folded collar band section of the body 5 and has` particular reference to a can having a flange member secured in place within the seam joining the body to its top so that removal of the tearing strip produces a reclosure cover having Vthe flange member embodied in the cover l this flange being adapted to frictionally engage the collar band of the can.

An object of the invention is the provision of a container having a tearing stripformed in a folded collar band section of the body and having l a ilange member secured in place within the seam uniting the body to its top wherein removal of the tearing strip produces a reclosure cover having a flange adapted to utilize the collar band as a friction base for holding the cover in place on 2o the container when it is used as a reclosure.

Another object is the provision of such a container wherein the flange member is formed from the material of the container body by folding the body wall back on itself and into engagement with the collar band, the folded flange member being incorporated in the seam uniting the body to its top so that removal of the tearing strip leaves the flange member connected with the can top to produce the desired flanged reclosure cover, 30 thereby making it possible to use the same simple form of can ends for both top and bottom instead of a different and more expensive special can top having the required flange wall formed therein and which would require more tin plate and would result in a greater waste of material.

Still another object is the provision of a container of this character wherein a wall section left by removal of the tearing strip from the folded section of the body, taken together with the flange 40 member, provide spaced flanges setting off an intervening pocket for sealing engagement over the top edge of the collar band when the cover is used as a reclosure.

Numerous other objects and advantages of the 45 invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawing, discloses a preferred embodiment thereof.

Referring to the drawing:

0 Figure 1 is a perspective view of a tearing strip flanged cover produced thereby and in separated relation to the opened can;

Fig. 4 is an enlarged fragmentary sectional View similar to Figs. 2 and 3 showing the flanged cover applied to the opened can and in use as a reclosure; and

Fig. 5 is an enlarged fragmentary sectional view similar to Fig. 2 illustrating a modified form, of the invention.

The container or can illustrated in the drawing as a preferred embodiment of the invention comprises a tubular body II (Fig. 1) having a bottom end I3 secured thereto in any suitable manner.

At the upper end of the can the body side wall is folded outwardly and downwardly upon itself and then upward as in a double fold to provide a folded section or band I5 of triple thickness or layers of body material extending around the body, as shown in Fig. 2. The two inner layers of the band form a smooth edged internal collar I which is surrounded by the outer layer (designated by the numeral I'I) which is preferably set back flush with the body wall so that the exterior surface of the can will be smooth and straight.

The outer layer I'I of the band I5 extends above the top edge of the collar I5 and is folded back on itself providing an annular wall or flange member I9 which extends back from a fold or top edge 2| whichis flanged over in the usual manner and incorporated in. a suitable seam 22 which permanently unites a can top end 23 with the body II. iI'he flange member I9 extends down inside the body adjacent the inner surfaces of the outer wall I'I and the collar band I6, the member being bent 'as at 24 to overlap the top edge of the collar band. The flange member preferably terminates adjacent the lower end of the collar band in an inwardly flared edge 25.

Spaced below the seam 22 in the outer layer I'I of the folded section I5 are

parallel score lines

21, 28 defining a tearing strip 29 extending around the body. One end of the tearing strip terminates in a tearing tongue 3l adapted for engagement by a key or other suitable tool for removing the strip in the usual manner to open the container.

Removal of the tearing strip 29 produces a flanged can cover 32 (Fig. 3) which may now be lifted off the can to open the same. This cover includes the can top 23, the flange member I9 and an upper wall section 33 formed by removal of the tearing strip from the outer layer I1. The member i9 which originally was a folded part of the body wall now provides a flange for the cover and is adapted to t within the collar band I6 utilizing th-e latter as a friction base when the cover is used as a reclosure (Fig. 4). This form of cover ilange permits the use of the same ordinary can end for the top that is used for the bottom instead of a more expensive and special form of can top having friction walls formed therein.

The wall section 33 is adapted to engage the exterior surface of the collar band, the upper edge of the latter being disposed in a pocket 34 (Figs. 3 and 4) provided between the ange member I9 and the wall section 33. The reclosure cover 32 is thus adapted to seat tightly over the top edge of the collar band to prevent accidental displacement of the cover and to protect the interior of the can against the entrance of foreign matter.

Fig. 5 of the drawing discloses a modified form of the invention in which the folded section I5 is formed on the outside of the body to provide a container having a straight internal wall instead of a straight external wall as illustrated in the other figures. In this form of container the inside layer of the collar band I6 is a continuation of and is in alignment with the body wall II and at the top this wall is folded outwardly and downwardly against the outside of the body to form the outside wall of the collar band and is thence folded outwardly and upwardly to form the outer wall I l.

The outer layer Il embodying the tearing strip 29 extends above the collar band i6 and is bent inwardly as at 36 to engage over the top of the collar and to align with the body wall II. The upper end of the layer Il extends up into the top seam 22 where it merges into the fold 2| and the flange member I9. In this form the flange member I9 extends straight down into the body and lays fiat against the inner surface of the body wall.

Removal of the tearing strip in the usual manner produces the flanged cover 32 in which the wall section 33 is again preferably present and in which the member I9 is again the inner fiange as described in connection with the straight external wall container of Figs. 1 to 4, inclusive. In like manner this flange I9 is adapted to engage within the collar band and the wall section 33 is adapted to engage the outside of the collar band in the same way when the cover is used as a reclosure. This form of the invention, like the form disclosed hereinbefore, permits the use of the same ordinary can end for the top that is used for the bottom instead of a more expensive and special form of can top having friction walls formed therein.

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 arrangement 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.
