COLLAR CAN COLLAR MOUNTING Filed July '7, 1944 Snventors Gttornegs Patented July 9, 1946 COLLAR CAN COLLAR MOUNTING John Coyle, Baltimore, Md., and William F. Punte, Passaic, N. J., assignors to Continental Can Company, Inc., New York, N. Y., a corporation of New York Application July 7, 1944, Serial No. 543,858

The invention relates generally-to well known tear strip or collar can structures and primarily seeks togprovide a; novel collar structure and mounting therefor.

In the well known tear strip cans `it is customary to provide a collar Within the upper prtion of the can in position for projecting upwardly beyond the end of the can b'ody after the tear strip is torn out to effect an opening of the can, thereby to provide a mounting neck over which the skirt or body portionk remaining attached to the top closure of the can when the tear strip is removed can be telescoped in order to effect a reclosure of the can. It is an object of the present invention to provide a novel collar structure so constructed and mounted as `to accomplish the intended purpose of providing a reclosure mounting without presentation of any raw metal edge portions in position where they can be contacted by a hand of a user of the can.

In its more detailed nature the invention resides in providing a can structure of the character stated with an outwardly directed bead ad-A 1 Claim. (Cl. 5520-54) `scribed in order to elect a reclosure The body 5 is provided with an outwardly directedl bead 8 adjacent the upper end thereof, and is scored in a manner well known in the art to p-rovide a tear strip 9 just above said bead. The tear strip is so placed that when it is wound about a key in a manner well known in the art so as to be torn out of the body of the can, it will separate the main b'ody 5 of the can from a skirt portion I0 in effecting an opening of the can. The skirt portion III remaining attached to the top end closure 'l is disposed to be telescoped over the collar which is constructed and mounted in the novel manner hereinafter deof the container.

The collar includes a cylindriform main body portion Il which is snugly telescoped into the upper end portion of the body in the manner illustrated in Figures 1 and 3 so as to project above the upper extremity of the body when the tear strip is removed in the manner above described.

. At its upper end the collar is provided with an jacent the upper end thereof, and a collar snugly telescoped in said upper end in position for extending above the upper end extremity` of the can body providedv by tearingout of the tear will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claim, and the several views illustrated in the accompanying drawing.

In the drawing:

Figure 1 is a side elevation and part vertical cross section illustrating a can embodying theY invention. Y

Figure 2 is an enlarged fragmentary vertical cross sectional view of the collar per se.

Figure 3 is an enlarged fragmentary vertical cross sectional view illustrating the c ol l ar mounting.

Ip the drawing the invention is illustrated as embodied in a can structure including a body 5, a lower end closure 6 and a top end closure 1.

inwardly directed curl I2, and at its lower end portion said collar is bent inwardly as at I3 and then outwardly as at I4 to present a lower edge extremity which normally does not extend beyond the diameter of the main body I I. See Figure 2. It will be apparent by reference to Figure 3 of the drawing, that the juncture of the inwardly and outwardly bent portions I3 and I5, respectively, of the lower portion of the collar is well rounded and spaced a considerable distance inwardly of the internal diameter of the collar main body portion so as to provide a protective shoulder effective toguard the raw metal edge extending into the can body bead 8 against contact by a hand ofv a user of the container. In the mounting of the collar the main body of said collar is snugly telescoped into the upper end of the can body 5 and then the lower outwardly bent end extremity I4 of the collar is mechanically displaced outwardly so as to project as an anchor as at I5 into the outwardly directed body bead 8. The bending of the lower end extremity of the collar into the body bead 8 serves the two-fold purpose of anchoring the collar II in the can, and also to place the lower edge extremity of the collar in said bead in position Afor being protected byfsaid extension into the bead against contact by a hand of a user of the can. The inwardly directed curl I2 'at the upper extremity of the collar alsol assures against presentation of raw metal edge portions for contact by a hand of a user of the can, and this curl additionally serves to facilitate telescoping of the closure skirt portion lll over-the collar in effecting reclosure of the can.

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 anapproved manner. An example ofthe last mentioned type of collar is shown in the copending application for U. Si. 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 seam the 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 band 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 4 and scope of the invention as defined in the appended claim.

We claim:

In a sheet metal container, a body portion, an upper end closure seamed onto the body portion, said body portion having an outwardly directed bead adjacent its upper'end, the body portion between said bead and the closure being scored to provide a tear strip, and a collar snugly fitting the body and having a main body portion lying opposite and extending above and below the tear strip and a lower end portion bent inwardly of the main body portion of the collar and then outwardly to present a raw metal end extremity as an anchor housed in said bead, the juncture of said inwardly and outwardly bent portions being well rounded and spaced a considerable distance inwardly of the internal diameter of the collar main body portion to provide a protective shoulder effective to guard said raw metal edge extremity against contact by a hand of a user of the container.
