vonostmn FOR TALCUM-POWDER CANS.

To all whom it may concern:

Be it known that I, WILLIAM G. KENDALL, a citizen of the United States, residing at Newark, in the county of Essex and State of New 'Jersey, have invented certain new and useful Improvements in Closures for Talcum-Powder Cans, of which the following is Faspecification. F

This invention relates to closures for talcum powder cans and similar containers and has for its object to providea comparatively pocket formed therein for the reception of a as the description proceeds.

" the cap and head.

simple and'inexpensive device of this character which may be conveniently opened to permit the dischar e of small quantities of powder, as require and which Wlll efi'ectually cut-01f the flow of powder and hermetically seal the'mouth of the can when moved to closed position.

A further objectof'the invention is to provide a closure including a cap having a strip of "cork or other yieldable packing, which latter bears against the head of 'the can and serves to close the discharge orifices and also serves to take up friction between A further object is to provide the cap with an arrow or other indicating device adapted to register with suitable indicia on the neck of the can for indicating the-open and closed A'still further object'is generally to improve this-class of devices so as to increase their utility, durability and efficiency.

Other and incidental objects will appear In the drawings wherein I'have illustrated the preferred embodiment of the invention, and wherein similar reference characters designate corresponding parts throughout the several Fig. 3 is a perspective View showing the different elements constituting the closure separated and in position to be assembled.

5 Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved closure forming the subject-- matter of the present invention is principa1ly,.designed. forapplication to talcum Specification of Letters Patent. v Patented J an. 21, 1919. Application filed September 18, 1918. Serial No. 254,617.

powder cans and similar containers and by way of illustration is shown in connection with a powder canof the ordinary construction in [which 5 designates the body of the can, 6 the bottom-and 7 an annular stop bead arranged near the upper-end thereof.

The device comprises a cover 8, preferably stamped or otherwise formed of metal and having a central opening therein and a depending flange 9 adapted to'fit over the top of the can or container 5 and bear against the stop rib 7, as shown. Secured to the cover ,8 is a cylindrical neck 10 having aflat upper head .11, the peripheral edge of which is pressed or rolled laterally to form a circumscribing flange 12. The neck 10 and headll are preferably stamped or pressed from a single'sheet of metal and the lower- 13 to grip the cover and thus secure the neck in position thereon.

Mounted for rotation on the head 11 is a cap or closure 15 having its marginal edge bent or rolled downwardly and inwardly to form a retaining flange 16 which fits over the flange 12 on the head and serves to prevent accidental displacement of the cap,

while at the same time permitting free rotation thereof on the head for the purpose hereinafter set forth. The peripheral edge.

of the cap is preferably milled or roughened, as indicated at 17, to permit the cap to be conveniently grasped and rotated when desired. The cap 15 is provided with spaced transverse slots18 adapted to register with suitable orifices 19 formed in the head 11 to permit the discharge of small quantities. of powder from the container as required. The metal constitutingthe cap 15 is preferably upstruck or pressed laterally to form an elongatedraised portion 20 defining a po ket adapted to receive a strip of cork, rubber,

wood or other yieldable packing, indicated at 21. The raisedporlion 20 is preferably disposed at substantially right angles to the slots 18 and stamped or otherwise represented on the upper surface of the upstanding portion 20 is an arrow 22 adapted to 1 register withv suitable indicia onnthe neck packing 21 not only serves to close the discharge orifices 19" and hermetically seal" the same when the cap is moved to closed. position, but by engagement 1with: the upper surface of the head'll serves to reduce friction between the parts and. also to slightly retard the "movementof the cap so as to prevent said cap from rotating too .ireelyt. While the: upstandingflportion 20' is preferably struck up. from the metal constituting. the

body of the cap 1'5-,i t will, of course, be 1111- derstood that, if desired, the portionQO-may be formed separatelyandi subsequently sol dered' or otherwise secured to the cap} The upstanding portion" 20- also serves as a convenient fingerpiece by ineansof which the cap may be rotated.

l-It will thus be seen' that by graspingeither the; roughened edge'1'71 ofjthe cap or -theupstanding portion 20" thereof and rotating' the cap in one". direction, the slots'1'8 will register with the orifices'19 so, thatby' tilting the can smell quantities1 of powder may be discharged therefrom and thatby rd- .tating the cap. in the opposite direction, the upstanding portion 20' will be moved to a" position over'the discharge orifices with the packing 21 bear-ing 'against the upper surface of the head 11 so a-sto form a liquid and moisture proof closure'for said orifices and thus hermeticz'tlly seal the discharge mouth of the" can. It will, of course,- be

understood that the upstanding portion 20 maybe of any desired length or width and that any desired number of discharge orifices may be formed in the head 11 without departing from the spirit of the invention. The,

closure being stamped or pressed from metal may be manufactured and placed on the market at a minimum costwhile at the same time producing an artlcle possessing maximum efliciency. 7
