v Filed July e, 1944 esmas-sheet 2 Patented July 2, 1946 COLLAR CAN COLLAR AND' MOUNTING THEREFOR William F. Punte, Baltimore, Md., assigner to Continental Can Company, New York; N. Yr, a corporation of New York v Application `Tuly 6, 1944, Serial No. 543,655

4 claims. (ol. )zzo- 54) *The invention relates generally to metallic re- K' ceptacles, 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 and a novel mountingr therefor.

Incans of the type stated the tear strips usually are defined by parallel score lines which surround the cans adjacent the upper end closure thereof, and a collar is snugly tted within the upper end of each canin position for extending upwardly from the upper extremity of the can body resulting from the tearing out of the tear strip, thereby to maintain the desired can body wall height and provide a support` neck' over which the skirt or bodywall portion remaining attached. to the upper vend closure can be telescop'ed to effect a reclosure of the can'. It is the purpose of the present invention 'to provide a novel collar and mounting structure in which no raw Ametal edges are.presented in position for being contacted by a hand of a user of the can,

and in which the collar i'sheld secure againstT movement downwardly or upwardly in the can.

Another object of the invention is to provide a novel collar and mounting therefor of the character stated in which the can body includes an inwardly directed bead 'just below the tear strip,

and the collar includes armain body disposed within the can body opposite the tear strip and extending above and below the same', and an inwardly directed bead structure spaced Within the can body bead and having upper portions resti ing as stop means onl the can body bead and a lower outwardly and upwardly curled endextremity engaging the can body immediately below its bead, therebyvto definitely place the collar with respectto the can body'bead and avoid. 1 presentation of raw-metal edge portions in position for being contacted by a hand of a user'v of the can.

Another object of the invention is to provide a collar of the character stated in which the upper f portions of the 'bead structure resting as stop means onv the can body bead constitute-y raw metal edge portions formed by slitting of the collar where it is bent inwardly to form its beadstructure.

With the above and other objects in View that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended i Z claims, and the several views illustrated in the accompanying drawings.V

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

Figure 2 is an enlarged fragmentary vertical cross section taken Aon the line. 2-2 on Figure 1.

Figure 3 is a view similar to Figure 2 illustrating the tear strip as torn out of the can body wall to effect an opening of the can and condition thev closure as a reclosure element.

,Figure 4 is a view similar to Figure 2 illustratingr a slightly modied form of the invention in which the inwardly bent upper portion ofthe collar bead structure rests directly on the can bodyl bead. l Figure 5 is an edge viewof the strip from which the collar is formed. v f

Figure 6 is a kface view Figure 5. Y v p Figure '7 is a fragmentaryihorizontal sectional View of the collar, the section being taken through theseam joiningn the ends rof the collar.

' Figure 8is a vertical cross section of the collar prior to formation of the lower bead structure thereon. v Y

Figure 9 is a view similar to Figure 8 illustrating the collar with the lower bead structure thereon formed prior to anchoring of the collar in the can body.

In this disclosure the invention is illustrated as embodied in a can including a can body 5 and the usual lower end closure 6 and upper end closure 1, both preferably seam secured to the body 5 in the manner well known in thel art.

Near Yits upper end the body 5 isv provided with an inwardlyV directed bead 8, and between the 4bead 8 and the upper closure 1 ythe body is scored in the conventional manner to provide a tear of the strip shownin strip 9 adapted to be wound on a key and in this manner torn out of the can body wall to effect an opening of the can in the Well known manner.

4The improvedl collar includes a main body portion l0 which when mounted inthe can snugly iits interlorly therein opposite the tear strip 9 and extending above 'and below said tear strip.

The collar isk provided at its upper extremity with an inwardly curled bead Il, and at its lower eX- tremityl with an inwardly directed beadstructure including an inwardly bent upper portion I2, an upright wall I3 spaced inwardly from' ltl'ie can body beadaS, and an outwardlyl and upwardly bent portion I4 terminating in an edge which engages the can'body 5 immediately below the bead 8.

It will be apparenet by reference to Figures- 1.,

y 2. 6, 8 and 9 of the drawings that the collar is i circumferentially slitted at space intervals as at v at which the collar wall is inwardly'bent as at I2 in the formation of the collar bead structure.

By .thus slitting the collar wall structure I6, IIn`-1` mediately beneath the bead 3D as at 33. Thus in Ythis form of the invention the collar is secured against upward movement by the upwardly and and placing said slitting in the manner stated,

inward bending of the collar wall as? at' I2lcau'ses' i the wall portions deiined by the slit equipments I 6, I'I to remain vertical in vthemanner clearly j outwardly bent lower edge extremlty 32 and the illustrated in Figure 2 and provide-raw edge stop '15 l and anchor the collar against downward movey ment. 1

`shoulders I8 which rest upon the can bead 8 In the formation of the collar the 'initially j' formed bead structure '12, I3 has its lower edge extremity ducked in slightly as at I9 in the man- I ner clearly illustrated in Figure 9.v Thispermits the collar to be inserted over .the can body` bead 8, and the inwardly-ducked portion I9 greatly facilitates outward end iipward curling of the lower extremity of the collar as at I4 in the final securing of the collar inthe can body. It will be apparent by reference to VFigures 2 and13 of `the drawings that the collar bead structure em- :braces the canbody beady 8 in spaced relation, lwith the raw metal fstop shoulders or .flanges I8 engaging the bead from above, and the outwardly and upwardly curled lower edge extremity l I4 engaging the vcan body .as at. I5 immediately belowthe can Ybody bead 8. rIn thisrnanner the t colla'ris securely held algainstimovement downwardly or upwardly in the canbody, and no `raw `edge portionsare presented in positionffor being contacted by ahand of a user of the can.'

3 VThe `collar may constitute a continuous drawn ring but in this disclosure it isshown as formed lfrom a band or strip of metal havinglits ends Ijoined by a seam inthe manner clearlyY illusltra-ted in Figures '7,r 8 and'9. The band or .strip .from which the collar may be made is indicated f 16, 8 andV 9 thatthe seam formed-bythe Hook and offset portionsV 2| and 22 terminates short of the ends ofthe collares at 24, and thusrthe` seam doesfnot. extend into the bead II. at ythe top of the collaror the bead structure h2, I3 at 'the ed form of collar includes a main body 21 and is inwardly curled as at 28' at its upper extremity. The inwardly bent portion 21 of the bead structure provided at the bottom of the collar provides a stop shoulder directly engageable with the can bodybead 30,*and said lower bead structure embraces the can body bead 30 in spaced relation and includes an upright wall portion 3| and an Aoutwardly and upwardly turned lower edge extremity 32 vwhich engages the can body wall iminwardly bent stop shoulder 29, the Ylatter befor purposes of illustration, it is to be clearly understood that various changes inthe detailsof construction and arrangement of parts may be made without departing from the spirit and scope of the invention las dened in the appended claims.

I claim:
