SAFETY DRINKING CUP Andre Tellier, New York, N. Y.

Application February 21, 1948, Serial No. 10,012

1 Claim. 1

This invention relates particularly to safety drinking cups.

A main object of the present invention is to provide a drinking cup that is safe to use on moving trains and the like.

Another object is to provide a cup of this kind with means for facilitating drinking therefrom and yet will prevent the spilling of the contents.

Another object is to provide such a cup with means for directing the flow of liquid over the lip of the cup in order to prevent spouting or spraying of the liquid.

Another object is to provide a cup of this kind with a removable cap having novel means for readily attaching and detaching the cap.

Other objects are to provide such a cup that is simple in construction, inexpensive to manufacture, sanitary and attractive in appearance.

The invention will be better understood from the description thereof to follow taken in connection with the accompanying drawing, in which- Fig. 1 is a vertical sectional view of a drinking cup embodying my invention, taken on the plane of the line ll of Fig. 3.

Fig. 2 is a side elevational view thereof with the parts spread apart or separated.

Fig. 3 is a top plan view of the cup.

Fig. 4 is a top plan view of the removable cap.

Fig. 5 is an enlarged sectional view taken on the plane of the line 55 of Fig. 1.

Referring to the drawing, my improved cup comprises a hollow tapered body portion 5 with a bottom wall 5 and surrounding base 1. The body portion, bottom wall and base are preferably formed integrally with each other and of transparent and translucent plastic material but of course may be made of any suitable material.

The upper open end of the body portion is larger in diameter than the remainder of the body portion thereby forming an inner shoulder 8. Removably seated on shoulder 8 is a cap or cover 9 in the form of a circular plate or disc of the same material as the body portion. Extending from the upper surface of said cap at its center is an integral handle ID. The peripheral edge of the cap is formed with spaced slots II, the outer edge walls l2 of which are tapered. Said peripheral edge, between each pair of adjacent slots II, is formed with an upstanding flange portion l3. The upper surface of each flange is tapered gradually upwardly from one end to the other thereby providing a camming 2 surface M as shown in Figs. 1 and 2, with a low end l5 and a high end IS.

The inner surface of the upper enlarged portion of the open end of the body portion 5 is provided with three spaced cylindrical integral studs [1, l1, I1. These studs are positioned above but adjacent the shoulder 8. The distance between the shoulder and the studs is slightly less than the depth of the highest portion of the flange I3 of the cap.

In mounting the cap onto the body portion, the cap is grasped by the handle It with its slots II positioned over and in alignment with the studs IT. The cap is then pushed downwardly so that the studs will be positioned above the lowermost portions of the surfaces of the flanges 13. The cap is then given a slight turn and the lowermost portions of the flanges I3 slid under the studs and because of the tapered surfaces of said flanges, the cap will be cammed or forced down by the studs on to its seat on shoulder 8, and inasmuch as the distance between the studs and the shoulder is smaller than the depth of the highest portions of the flanges, the studs will become interlocked with the flanges and thereby securely hold the cap on its seat. The tapered edge walls l2 of the slots ll facilitate and guide the slots onto the studs. To remove the cap, it is only necessary to turn the cap backward slightly to bring the slots into register with the studs.

The cap of course will prevent the liquid in the cup from spilling out and the slots as shaped and arranged as shown permit the easy flow of the liquid and direct it outwardly toward the inner surface of the upper open end of the body portion thereby preventing spouting and spraying.

I claim:

A safety drinking cup comprising a hollow body portion and having an open top end, an inner shoulder on the body portion below said open top end, spacedstuds extending inwardly from the inner surface of the body portion above and adjacent said shoulder, a detachable cap seated on said shoulder, said cap having spaced slots along its periphery communicating with the interior of the hollow body portion, said slots having flared outer edges, upstanding flanges formed on one surface of said cap at its periphery and between the slots, said flanges having upper tapered camming surfaces, the highest portion of one flange being arranged adjacent the lowermost portion of the adjacent flange whereby the lowermost portion is presented to the studs, said studs being adapted to coast With said camming surfaces for detachably ANDRE TE'JLJLIIERI.
