1 Claim.
The invention relates generally to metallic receptacles, and more particularly to the type known as collar cans wherein are provided tear strip structures adapted to be wound on keys and by this means torn out of the body walls of the cans in order to effect an opening thereof, and it primarily seeks to provide a novel collar structure for such cans so formed that it can be mounted and anchored in the can by mere insertion of the collar into the can body and application of. pressure sufficient to force the collar the required distance into said body.
In cans of the type stated the tear strips usually are definedby parallel score lines which surround thecans adjacent the upper end closures thereof, and a collar is snugly fitted within the upper end of each can in position for extending upwardly fromthe upper extremity of the can body resulting from the tearing out of the rip strip, thereby to maintain the desired can body wall height and provide a support neck over which the skirt or body wall portion remaining attached to the upper endclosure can be telescoped to eiTect a reclosureof the can. It is the purpose of the present'invention to provide a novel collar and mounting structure in which the can body is provided just below the tear strip with an inwardly directed bead composed of an inwardly and downwardly angled cam wall and an abruptly angled, outwardly directed anchor shoulder, said collar including a main body disposed to lie opposite the tear strip and extending above and below the same, said main body terminating upwardly in an inwardly curled bead and downwardly in an inwardly directed bead structure dimensioned to fit within and over the can body bead and composed of an inwardly directed upper flange portion, an upright wall portion spaced a distance inwardly of the main body to provide a space into which the can body bead may project, and an outwardly turned abruptly angled lower anchor flange adapted to snap under and lock behind the anchor shoulder portion of the can body bead as the collar is forced into the can body a distance for causing said anchor flange to ride over and beyond the cam wall portion of said body bead.
Another object of the invention is to provide a structure of the character stated in which the inwardly directed upper flange portion of the collar bead is disposed to engage the cam wall portion of the can body bead in a manner for preventing additional movement of the collar into the can body after the anchor flange has snapped into collar locking position behind the anchor shoulder.
With the above and other objects in View that will hereinafter appear, the nature of the invention will be more fully understood by following the detailed description, the appended claim and 2 the several views illustrated in the accompanying drawing:
Figurel is a part side elevation and part vertical cross sectional view of a can embodying the invention;
Figure 2 is an enlarged, fragmentary sectional view illustrating the collar fully mounted in full lines, and as partially inserted into the can body in dot and dash lines;
Figure 3 is an enlarged, fragmentary sectional view of the collar per so;
In this disclosure the invention is illustrated as embodying a, can having a body 5, a lower end closure 6, and an upper end closure 1, said end closures preferably being seam securedonthe can body in the conventional manner.
Adjacent its upper end the body 5 is equipped with an inwardly directed bead generally designated 8. This bead is so formed as to comprise an inwardly and downwardly angled cam wall which merges into an outwardly extended, abruptly angled anchoring shoulder I0.
Above the bead generally designated 8,.the can body is scored in the conventional manner to provide a tear strip II adapted to be wound on a key in the manner well known in the artfor being removed from the can body wall to efiect an pening of the can.
A collar including a main body portion I2 fits snugly within the can body opposite the tear strip II, said main body being extended above and below said tear strip. The collar is provided with an inwardly curled bead I3 at its upper extremity, and with an inwardly directed bead generally designated I4 at its lower extremity. The collar bead I4 is formed to comprise an inwardly and downwardly directed upper flange portion I5, an upright wall portion I6, and an outwardly turned, abruptly angled anchor flange I7.
It will be apparent by reference to Figures 1 and 2 of the drawing that the collar bead structure I4 is dimensioned to fit Within and over the can body head 8, and when the collar is properly mounted in the can body in the manner illustrated in Figure 1, and in full lines in Figure 2, the anchor flange portion I1 of the collar bead I4 is securely looked under tthe shoulder III of the can body bead 8, as at I8.
During the insertion of the collar into the can body the collar is initially inserted into the upper end of the can body, and as the lower or anchor flange portion I1 of the collar bead I4 engages the cam wall portion 9 of the can body bead 8, the collar bead will flex inwardly in the manner indicated in dot and dash lines in Figure 2. This inward flexing of the collar bead will continue until the collar bead flange portion I1 passes completely over the cam wall portion 9, and then said flange portion will snap under the shoulder ID of the can body bead 8, and securely lock the 3 collar in place in the manner above described. The collar bead I4 is so proportioned that when the anchor flange ll has moved into locking engagement under the can body shoulder [0, the upper flange portion ['5 of the collar bead will have contacted the cam wall portion 9 of the can body bead and will prevent additional movement of the collar into the can body. 7
By forming and mounting the collar in the manner hereinbefore described, said collar will not only be securely anchored in the can body, but it will be so mounted as to present no raw metal edge portions in position for being contacted by the hand of a user 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 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 seam the multiple thicknesses of collar band metal are disposed only at the central cylindriform body portion 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 claim.
I claim:
In a sheet metal container a body portion having an upper end extremity, said body portion having an inwardly directed bead spaced downwardly from said upper end extremity and composed of a wall portion flat in vertical cross section and inclined downwardly and inwardly at an acute angle to the vertical and an anchor shoulder wall portion extending outwardly and downwardly in approximate right angular relation to said wall portion, and said body portion between said pad and said end extremity 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 and terminating upwardly in an inwardly curled bead and downwardly in an inwardly directed bead structure dimensioned to fit within and over the can body bead and composed of an inwardly directed upper flange portion disposed to seat against the inwardly and downwardly inclined body bead wall portion and prevent downward movement of the collar, an upright wall portion spaced inwardly from the collar main body a distance sufficient to provide a space into which the can body bead projects without contacting said upright wall portion, and an outwardly turned abruptly angled lower anchor flange adapted to snap under and look behind the anchor shoulder portion of the can body bead in contact with the can body as the collar is forced into the can body a distance for causing said anchor flange to ride over and beyond said inwardly and downwardly inclined body bead wall portion.
