CLOSURE ASSEMBLY FOR A DRINKING CUP

摘要

A closure assembly for a drinking cup is disclosed. It comprises an annular body (5) mountable to an open upper end of a cup (3) and having a rim (8) to enable a user to drink liquid from said cup through the annular body (5). A closure member (9) is disposed within said body (5) and is positionable so as to extend across the open upper end of the cup (3) to which the body (5) is mounted. The closure member (9) has a plurality of apertures (12) in it. A sealing element (14) is located on an inner side of the closure member (9) and an actuator (15) on the opposite side of the closure member (9) which is accessible to a user when said closure assembly (2) is mounted to a cup (3). The sealing element (14) and actuator (15) are coupled to each other with the sealing element (14) biased into a rest position in which it is urged against said inner side of the closure member (9) to block said apertures (12) and prevent the flow of liquid therethrough. The arrangement is such that the sealing element (14) is moved out of said rest position to allow liquid to flow through said apertures (12) and out of the vessel when pressure sufficient to overcome said bias is applied to the actuator (15) by a user.
