1 Claim. (cl. 220-54) The invention relates to new and useful improvements in metal containers, and more particularly to a container having a tearing strip which may be removed in the opening 01' the conta er. An 0 ject of the invention is to provide a metal container of the above type with an inserted collar made from a strip of metal having the ends thereof abutted and interengaged so as to previelrl t lateral movement of one end relative to the 0 er. a I

A further object of the invention is to provide a container of the above type wherein the ends of the collar are so inter-engaged as to prevent separation of the ends as well as lateral movement -.closed.

- In the drawimz- Figure l is a vertical sectional view through the container embodying the improvements:

Fig. 2 is asectional view-through a portion of a collar embodying the improvements;

Fig. 3 is a view showing the two ends of the stri vler:l forming-the collar, said ends being separa 4 Rig. 4 is a view showing the ends ofthe strip interengaged and joined by soldering;

5 is an edge view of the parts shownin 8- i Fig. 6 isa view showing-a slightlymodified form of inter-engaging connection Joining the ends of the strip from which the collar is made,

Fig. '1 is a view similar to m. 6,'showing a'iurther modified form of inter-engaging connec tion.

The invention is embodied in a metal container which includes a body portion I having an end 1 2 secured thereto by a doubles'eami. There is,

of course, a

within the body of the container is a collar 6 hich ispreierably'madeof a diameter slightly greater than the inner-diameter oi the container body'so that when ,the collar. is forced into the container. it will irictionally" grip oi the container-andbe held in place therein; It is tllit contacts with said shoulder.

' ing strip.

ttom end similarly secured to the g body of the ontainer. The body wall is scored at 4 adjacent the double seam, and at I: setting understood, however, that the collar may be held in inothenways than by africtional grip. The body wall ofthe container is preferably provided with a head 1 which forms a shoulder, and the collar is preferably forced into the container un-' 5 y en the colhat is placed in the container, it exte to a point adjacent the upper score line 4. The upper part 6 of the-collar, as shown, is-inset so as to provide a space therebetween and the. wall at the con- 10 tainer. This inset portion is located above .the lower score line 5. The collar at the upper end thereof is rolled into a hollow strengthening head 8.. The containerend 2 is shaped by,drawing so as to provide a depending portion 9 which ex- 1 tends into the container body in rear of the tear This depending portion also lies between the inset portion of the collar and the body wall.

The present invention is directed particularly 2( to the manner in which the ends of the collar are v joined, and it will be understood that the particsular shaping of the collar and the can'end for reclosure purposes may be greatly varied without indicated at ii in the drawing. In the preferred form of thev inventiomone'end of the tr p is provided with-a dove-tailed shapedproiection I l0, while the other end of the strip isprovided with a similarly shaped recess II- when the projection is inserted in the recess, the ends 35 Joined. "The .ends are inthe same plane and they abut, making contact all the way across the strip; This particular shaping of the inter-engaging parts will hold the ends so as not .only to prevent separation, when strains are applied to the collar which tend to expand the same, but also to prevent lateral movement oi one end re1a-; tive to the other It holds the two ends firmly abutted-and in alinement; It is understood, of I course, that when the two-ends are joined, the collar blankis cylindrical in form. In order to -prevent the ends from slipping out of allnement After the: ends of the strip have been then u jecting portions are shaped so as to provide relatively large rounded heads with a. narrow neck so that when the projections are nested in the recesses, the ends of the strip will be held from separation in a direction lengthwise of the strip, v as well as from movement laterally in the plane of the strip. As shown in Fig. 6, solder is applied as indicated at It for joining the ends. The ends, however, may be secured in their nested or inter-engaged position in any suitable way,

either by solder bonding, welding, or by a irictional oversize fit between the parts. The same is true of the construction shown in Fig. 3.

In Fig. 7 there is shown a slightly further modifled form of the inter-engaging parts. The projecting members l5, l5 carried by one end of the strip l0 are spaced, but are of substantially the same width in the planeof the strip throughout. The recesses are similarly shaped so that there is an abutted connection between the two ends of the strip. These projections will prevent any possible movement of .the ends of the strip in theplane of the strip out of alinement. The solder bond may be used for joining the ends of the strip as indicated at I 6. Instead of the solder bond, the ends may-be welded, and it is the fused metal bonding the ends together that prevents the ends from separating." It will be understood that the shaping of the projecting portions and the recesses may be greatly varied from that disclosed in the drawing. The essential features reside in the providing of one or more projections on one end with similarly shaped tainer, it is necessarily put under strain, which 5 tends to contract the collar. This strain on the collar is taken in the. present construction through the abutted end on contact all the way across the strip; There is also a strain laterally oi. the'collar in the plane of the strip during the handling and the insertion of the collar and the inter-engaged parts will hold the ends in per- Iect alinement. 7

It is obvious that minor changes in the shaping of the parts and the details of construction 18 may be made without departing from the spirit of the invention as set forth in the appended claim. I

Having thus described the invention, what I claim Patent,

A metal container comprising a body portion, an end secured thereto by seaming said body portion having score lines adjacent one end there-' of forming a rip strip, a collar disposed within 25 said body so that the upper end extends above the lower score fine, said collar being formed .from a strip having the ends thereof abutted so that said collar is of uniform diameter through out the entire extent of the collar, said collar being dimensioned so as to irictionallycontact with the inner wall of the container whereby said collar isheld within the container, one of said abutted ends of the collar having a projecting portion adapted to flt within a recess formed in the other end of the collar strip, said projecting portion and recess being shaped so as to prevent separation of the ends or lateral movement of one end relative to the other in an endwise direction and aimed metal bond for securing said interengaging portions together.
