Abstract: 355,279. Drinking-vessels. KAUFMAN, S., 55, West 110th Street, New York, U.S.A. May 9, 1930, No. 14367. [Class 128.] A non-spillable drinking-vessel &c. is provided with a closure comprising a plurality of members located at the mouth and capable of movement relative to each other, one at least being rotatable, so that in the event of the vessel being overturned the mouth will be closed or retained closed, to prevent appreciable spilling of the contents, the closure members being retained on the vessel during discharging or refilling thereof. Figs. 2 and 3 represent the preferred embodiment in which two members G, F, free to rotate in grooves E, D, are gravity biased by upstanding flanges G<1>, F<1>, so that in the event of overturning the members will rotate in their grooves, the opening of the one being closed by the projecting portion of the other. In a modification, a gravity biased rotating member, with an aperture to one side, is formed hollow, and a slide, which may be manually operated, operates in the hollow to cover the aperture on the tilting of the vessel. In another modification, a gravity biased spherically shaped member 66, Fig. 14, is universally pivoted at 67, 69, so that on the vessel being overturned the aperture will be closed. In a further modification, Fig. 9, a horizontally pivoted disc 55 is normally retained in the closed position by the weight of a vertically movable sleeve 59. The vessel is lifted bv the sleeve, the two portions sliding apart until a lug 61 reaches the top of a groove 62, when the disc may be rotated to the open position. Alternatively, the closure may consist of two members 43, Fig. 5, formed as parts of a sphere, each of which engages by a sliding undercut guide with the wall portions 45. The vessel is lifted by the sleeve 40, the bottom portion of the vessel moving relatively downwardly until a pin 46<1> has engaged the top of the slot 46. During this action, the spherical portions 43 rotate in their guides, resting meanwhile on the top edge of the vessel, thus opening the mouth.
