CAN-CLOSURE.

' and HENRY G. WELLs, citizens of the United States, residing at Crisfield, in the county of Somerset and State of Maryland, have invented certain new and useful Improvements in Can-Closures; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to can closures, and has for an object to provide a closure, embodying improved features of convenience, reliability, and economy.

A further object of the invention is to provide a can closure, embodying a slip cover, having a tongue extending circumferentially in relation to the flange 'of the cover, and produced by an L shaped slot, with an ear or loop struck up from the flange of the can body, positioned to receive the tongue of the cover member when the cover is slipped to position, and rotated upon the can.

With these and other objects in view, the invention comprlses certain novel features of constructlon, combmatlons and arrangements of parts, as will hereinafter be more fully described and claimed.

In the drawing; Figure 1 is a perspective view of the can with the cover lifted.

Fig. 2 is a vertical sectional view through the struck up loop, and transversely through the tongue.

Like characters of reference designate corresponding parts, throughout the several views.

The improved can closure which forms the subject 'matter of this application, is adapted to-be applied to almost any type of cylindrical cans, as indicated at 10, having a flange 11, and preferably although not necessarily, also a head 12.

The cover' member 13, is in general appearance of the usual and ordinary slip type, having a flange 14:, which however, 1s pro- Specification of Letters Patent. Patented Aug, 11.2, 11.91190 Application filed March 11, 1918.

Serial No. 221,852.

vided with an E. shaped slot 15, producing a tongue 16, having its major axis extending circumferentially of the cover flange.

At an appropriate point in the body flange 11, a loop 17 is struck up by the producing slits 18, in substantial parallelism, extending also in parallelism with the axis of the can body. The loop 17 is then forced outwardly from the axis of the can, so that the opening of such loo or the interval between the loop member 1 and the surface of the body flange, is in the path of movement of the tongue 16, as it is moved circumferentially.

In operation, the can cover is placed upon the body flange in substantially the usual and ordinary manner, and is then rotated manually in the direction opposite to that indicated by the arrows, upon the body flange and the cover flange, until the tongue 16 has entered the loop, and has been moved to its limit of circumferential movement. In this position it is obvious that the cover is firmly locked against displacement. To remove the cover, the cover is rotated in the direction indicated by the arrows, until the tongue 16 has been released from engage- \the flange, 3. cover having a flange proportioned to slipvover the flange of the can body, and to be manually rotated relatively thereto, and a tongue formed in said cover flange by an L shaped slot, said tongue being positioned and proportioned to slip through the loop when the cover is rotated.

In testimony whereof we affi-x our signatures.
