3 Claims.

The invention relates generally to metallic receptacles and more particularly to can structures of the tear strip type including a tear strip which can be wound about a key to effect an opening of the can, and it primarily seeks to provide a novel collar and mounting therefor, said collar being disposed to project from the open top of the can after the tear strip has been removed in position for acting as a support for a reclosure cover.

In collar cans of the type referred to it is customary to provide a collar within the upper end of the can in position for projecting from the open top of the can after th tear strip has been removed so as to provide a neck extension over which the upper end of the can removed by tearing out of the tear strip can be telescoped to effect a reclosure of the can. It is an object of the present invention to provide a novel form of collar and a mounting therefor effective to securely position th collar in a manner for avoiding presentation of any raw edges of metal which can readily be contacted by a person handling the can.

In its more detailed nature, the invention resides in providing a can structure of the character stated in which there is provided near the top of the can a bead structure which is S-shaped in vertical cross section so as to provide an upper bead portion extending interiorly and a lower I bead portion extending exteriorly of the can. and a collar telescoped within the upper portion of th can and including an inwardly curled upper end extremity projected above the tear strip, a

lower abutment shoulder for seating on the upper portion of the inwardly directed bead portion, and a lower extremity or flange portion mechanically turned outwardly so as to project into the outwardly directed bead portion so as to anchor the lower extremity of the collar therein and dispose said lower edge extremity in position Where it cannot readily be contacted by the hand of a user of the can.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reierence to the following detailed description, the appended claims, and the several views illustrated in the accompanying drawing.

In the drawing: Figure 1 is a part side elevation and part vertical cross sectional view of a can embodying the invention.

Figure 2 is a fragmentary vertical cross sectional view illustrating the collar per se.

rected bead .portion 8 and a lower outwardly directed bead portion 9. Just above the bead structure 8, 9 the container body is scored in a manner well known in the art to provide a tear strip i0 which may be wound upon a suitable key and torn out of the can structure so as to eilect'a separation of the closure 1 and the neck portion ll of the can body immediately below said closure in effecting an opening of the can.

In order to provide for convenient reclosure of the container, a collar I2 is mounted in the container body in position for projecting from the open upper end thereof after the tear strip l0 has been torn away. The present invention is directed principally to the structure and mounting of said collar. The collar is initially constructed in the manner illustrated in detail in Figure 2 to include an inwardly curled upper end extremity l8 and a cylindriform main body portion terminating at its lower end in a stop shoulder l4 which merges into an inwardly curved portion l5 conforming in curvature to the upper half of the upper bead structure portion 8, and a downwardly extended generally cylindriform portion H3.

In the formation of the can structure the main body of thecollar I2 is snugly telescoped into the upper end of the body 5 with the stop shoulder l4 thereof resting upon the upper bead structure portion 8 in the manner clearly illustrated in Figure 3. After the collar has been inserted in this manner into the can body, the generally cylindriform lower extension i8 thereof is 'mechanically turned outwardly into the lower bead structure portion 9 of the body 5 so as to securely anchor the collar in the bpdy in the manner illustrated at I! in Figure 3. It will be apparent by reference to said Figure 3 that the provision of the S-shaped bead structure 8, 9 permits outward turning of the collar anchoring extremity ll beyond the vertical plane in which an upright section of the can body 5 lies.

It will be obvious by reference to Figures 1 and 3 of the drawing that after the tear strip ID has been torn out in the manner well known in the art, the upper portion ll of the can body and the attached closure 1 can be lifted from the collar I2 to effect an opening 01' the container. Projection of the collar l2 above the upper extremity of the can body 5 left by tearing out of the tear strip Ill makes it possible to readily telescope the closure sk rt i I over the projecting collar portion whenever it is desired to effect a reclosure or the container. It will be obvious that the mechanical turning of the lower end extremity of the collar into the lower bead structure portion 9 securely anchors the collar in position with the stop shoulder l4 thereof solidly engaging the upper bead structure portion 8. The positioning of the lower edge extremity of the collar in the manner stated and the inward curling 01 the upper extremity of the collar as at [3 assures against presentation of raw edge metal portions in position for being contacted by the hand of a user of the container.

By making the bead structure 8, 9 S-shaped in cross section, it is unnecessary to make either bead portion of great depth, and it will be readily appreciated that it may be found desirable to make the bead portions relatively shallow so as not to necessitate sharp bending of multiple wall thicknesses at the position of side seam structures.

It is to be understood that the collar herein disclosed may comprise an endless band such as would be formed from a drawn ring, or it may be shaped from a strip joined at its ends in an approved manner. An example of the last mentioned type of collar is shown in the copending application for U. S. Letters Patent Serial Number 543,655, filed by William F. Punte on July 6. 1944. When collars formed from end joined strips are employed, the joint or seam disclosed by Punte will be found desirable because in this form of joint or seamthe multiple thicknesses of collar band metal are disposed only at the central cylindriform body of the collar and no overlapping of wall thicknesses is presented at the upper edge curl or the lower edge bend portions of the collar.

While one form of the invention has been shown for purposes of illustration, it is to be clearly understood that various changes in the details of construction and arrangement of parts may be made without departing from the spirit and scope of the invention as defined in the appended claims.

We claim:

1. In a sheet metal container, a body portion, an upper end closure seamed onto the body portion, said body portion having an S-shaped bead structure adjacent its upper and including an inwardly directed upper head portion and an outwardly directed lower bead portion, the body portion between said upper bead portion and the closure being scored to provide a tear strip, and a collar snugly fitting within the body and having a main body portion lying opposite and extending above and below the tear strip with its lower extremity resting as a stop on the upper head portion and its upper extremity formed into an inwardly curled head, said collar also including an integral bottom extension conforming to the curvature of the upper bead portion and terminating in a raw metal edge extending outwardly as an anchor into the lower bead portion.

2. In a sheet metal container, a body portion, an upper end closure seamed onto the body portion, said body portion having an S-shaped bead structure adjacent its upper end including an inwardly directed upper bead portion and an outwardly directed lower bead portion, the body portion between said upper bead portion and the closure being scored to provide a tear strip, and a collar snugly fitting within the body and having a main body portion lying opposite and extendin above and below the tear strip with its lower extremity resting as a stop on the upper bead portion and its upper extremity formed into an inwardly curled head, said collar also including an integral bottom extension conforming to the curvature of the upper bead portion and terminating in a raw metal edge extending outwardly as an anchor into the lower head portion into position for causing said lower bead portion to house the raw edge extremity of said anchor extension against contact by a hand of a user of the container.

3. In a sheet metal container, a body portion, an upper end closure seamed onto the body portion, said body portion having an S-shaped bead structure adjacent its upper end including an inwardly directed upper bead portion and an outwardly directed lower bead portion, the body portion between said upper bead portion and the closure being scored to provide a tear strip, and a collar snugly fitting within the body and having a main body portion lying opposite and extending above and below the tear strip with its lower extremity resting as a stop on the upper bead portion and its upper extremity formed into an inwardly curled bead, said collar also including an integral bottom extension conforming to the curvature of the upper head portion and terminating in a raw metal edge extending outwardly as an anchor into the lower head portion and outwardly beyond the inner diameter of the container body portion.
