Application filed March 11, 1926; Serial No. 94,028:

This invention relates to closure means.

for metallic cans and particularly t'o those closure members which are separable from the cans without the use of can openers.

' Various attempts have been made to produce a closure member for metallic cans wherein, by the pulling of a wire, the closure member will be separated from the can. These constructions,,,thus far produced, are open to one objection or another. In most types, it is difficult to holdthe can while the wire is being pulled. This results in spilling the contents of the can. In some types, 1t is difficult to secure the wire in place while the closure member is being sealed in place.

The primary object of my invention is' the provision of an improved easily sealed and opened closure member which will nothave the above objectionable features.

Another object of my invention is the provision of a closure means for a metallic can wherein is provided a wire loop by which the closure member may be loosened and separated to gain access to the interior of the can.

Other and further objects of my invention will be apparent to those skilled in the art, from a reading of the complete specification.

Referring to the drawing wherein I have 0 illustrated an embodiment of my invention,

Fig. 1 is an elevational view of my invention showing the wire loop in osition to apply a knife handle or other lmplement for the separation of the closure member .from the can.

Fig. 2 is a cross sectional view on the line 2-2 of Fig. 1. Y

Fig. 3 A is a fragmental view on an enlarged scale showing the method of fastening the two ends of the opening wire together.

Fig. ,4 is a top View of the can showing .one

way of placing theloop to have the same out of the way and at the same time assist in the can-filling and sealing operations.

Figs. 5, 6 and 7 illustrate one way of easily opening the can by my invention.

- The same reference characters refer to the same or similar parts throughout the several views ofthe drawing.

10 designates the body of a can of conventional form to which I have shown my invention applied. The cover or top, 11' is shown with a downwardly extending flange 12 to provide for a holdm means for the opening wire to be described and as a means a sealed joint is indicated at-1 the lower edge of the cover flange, is placed the opening wire 14. This opening wire 14 extends around the body portion 10 of the can and has its ends preferably secured together as by twisting as shown at 15 in Fig.

3. At one point as shown at 16 in Fig. 1,

the two parts are brought together and extend outwardly to form the loop 17.

In order to secure the cover or top 11 in place, I use solder or other suitable sealing material to make a sealed joint between the cover'll and the body 10 of the 11. Such where the solder is shown as being connected to the can body 10 and the rim 13. Where the two parts of the opening wire loops 17 come out fromunder the rim 13, as at 16, the. solder or other sealing agent surrounds the wire and makes a tight joint.

In filling and sealing the can, any suitable method of holding the opening wire loop in place may be used. In the embodiment herein illustrated, the wire may be placed in the flange 12 and folded over the top as V illustrated in Figures 3 and 4. The opening wire will thus holditself in place while the cover 11 is being applied to the can body 10. ,The sealing operation may be carried .out in any suitable or well known manner, the solder being applied to hermetically-seal the cover ,11 to the can body 10. As there ,are many devices for performing this soldering operation, and as this is not a part of this invention, the details of carr ing out this operation will not be describ n I will now describe the opening operation which is illustrated in detail in Figs. 5, 6 and'7.

The loop 17 which might be on the top of the can, as shown in Figs. 1 and 1, is brought down to a position as shown in Fig.- 1. ThBdOOP is of a length to extend substantially to the bottom of the can as shown in Figs. 1 and\ 5. As shown in Fig. 5, the a other ledge is available, the end of the knife handle may be placed under the bottom of the can itself With one hand holding the can steady upon the table or other suitable surface, pressure is exerted upon the outer end of the knife 18'. This draws downwardly on the loop and causes the solder 19 to break away as shown in Fig. 6. 'The action is continued as shown in Fig. 7 until the can cover 11 is free to be lifted from the can body 10. It is to be noted that, during this operation, the twisted ends 15 of the opening wire 14 hold the same from slipping and that this construction does not make it absolutely necessary that the wire be soldered at any place except at the point 7 16 where the loop parts come from beneath the cover rim 13.

The result of the use of my invention is that can openers are unnecessary, any elongated body, which can be placed through the loop and used as described, being suflicient. Further, this is accomplished without injury to bands.

In addition, the loops of cans may be used to enable several cans to be carried by the fingers of a person or the loops may be used to hang the cans from hooks or nails in the wall.

While I have described in detail an embodiment of my invention, I desire to have it understood that I do not limit myself to the exact showing and that modifications and changes may be made without departing from the spirit of my invention and within the scope of the appended claims.

Having described my invention what I claim is: r

1. In combination, a metallic can or receptacle, a cover therefor, means for sealing the cover to the can or receptacle, a flex- .ible elongated metallic member adjacent the sealing means and having a free loop portion extending away from the sealing means and. of suflicient length to insert a tool therethrough, thereby to provide a seal breaking means when it is desired to open the can or receptacle, both ends of the loop being in contact with the sealing means, one part ex-' tending one way around the side of the can or receptacle and the other part extending around the other way whereby the can may be opened b exerting a pull on the loop, with the too without imparting a rotating tendency to the can.

2. In combination, a metallic can or receptacle, a cover therefor, a flange on the cover extending around the edge of the can or receptacle, a flexible elongated metallic opened, without imparting a rotary tendency to the can.

In combination, a metallic can or receptacle, a cover therefor, a flange on the cover extending around the edge of the can or receptacle, a flexible elongated metallic member between the flange and the body portion of the can or receptacle and extending about the said body portion,

the other way whereby the can may be means for sealing the flange to the body portion, the flexible elongated metallic member having a loop portion extending out through the sealing means and of a length to reach substantially to the bottom of the can or receptacle, one part of the loop extending around the side of the can or receptacle one way and the other part extending around the can or receptacle the other way.

4; In combination, a metallic can or receptacle, a cover therefor, a flange on the cover extending around the edge of the can or receptacle, a flexible elongated metallic member between the flange and the body portion of the can or receptacle and extending about the said body portlon, means for sealing the'flange to the body portlon, the flexible elongated metallic member having a loop portion extending out through the sealing means and of a length to reach substantially to the bottom of the can or receptacle, one part of the loop extendmg around the side of the can or receptacle one way and the other part extending around the can or receptacle the other way, the two ends of the elongated metallic member being secured together on the opposite side of thecan from the position of the loop.'

In testimony whereof- I hereunto aflix my signature.

ELIZABETH M, CARHART.
