A closure assembly for a drinking cup includes an annular body, with a rim for drinking, mountable to a cup. A closure member, having apertures, is disposed within the body and extends across the cup. A sealing element, on an inner side of the closure member, and an actuator, on the opposite side of the closure member, are coupled to each other with the sealing element biased into a rest position in which it is urged against the inner side of the closure member to block the apertures and prevent liquid flow therethrough. The sealing element moves out of the rest position to allow liquid flow through the apertures when pressure sufficient to overcome the bias is applied to the actuator. The closure member includes a diaphragm that is integrally formed with a biasing member to bias the sealing element into the rest position.

1. A closure assembly for a drinking cup, comprising: an annular body mountable to an open upper end of a cup and having a rim to enable a user to drink liquid from said cup through the annular body;a closure member within said annular body positionable so as to extend across the open upper end of the cup to which the annular body is mounted and having a plurality of apertures and a central opening, therein;a sealing element positioned on an inner side of the closure member and comprising a socket extending in a first direction from the sealing element and toward the closure member;an actuator positioned on an opposite side of the closure member opposite the inner side and comprising a plug extending in a second direction opposite the first direction from the actuator and toward the closure member which is accessible to the user when said closure assembly is mounted to the cup,wherein the sealing element and the actuator are coupled to each other,wherein a portion of the plug is positioned through the closure member and within the socket, with the sealing element biased into a rest position in which it is urged against said inner side of the closure member, and contacts said inner side with an upper side of the sealing element, which in the rest position runs parallel to the closure member, to block said apertures and prevent the flow of liquid therethrough,wherein the actuator comprises a lip contacting portion that extends over the closure member towards said rim on the annular body, the arrangement being such that the sealing element is moved out of said rest position to allow liquid to flow through said apertures and out of the cup when pressure sufficient to overcome said bias is applied to the lip contacting portion by the user; anda biasing member to bias the sealing element into the rest position, wherein the closure member comprises a deformable diaphragm, wherein the biasing member is integrally formed with said deformable diaphragm, and wherein the deformable diaphragm has a raised region surrounding the central opening that spaces the lip contacting portion from the apertures, said biasing member being formed from said raised region surrounding the central opening, wherein the central opening is formed through the raised region. 2. The closure assembly according to claim 1, wherein said lip contacting portion is spaced from the apertures in said closure member to form a fluid flow path between said apertures and the rim. 3. The closure assembly according to claim 1, wherein said lip contacting portion is configured such that, when the user places their upper lip over the rim to take a drink, their upper lip applies pressure to the lip contacting portion sufficient to overcome said bias to move the sealing element out of its rest position. 4. The closure assembly according to claim 1, wherein the actuator and the sealing element each comprise a cooperating connecting element to rigidly connect the actuator and the sealing element to each other with the closure member therebetween. 5. The closure assembly according to claim 4, wherein said cooperating connecting elements cooperate with each other through the central opening in the closure member. 6. The closure assembly according to claim 4, wherein the lip contacting portion of the actuator is disc-shaped and said cooperating connecting element of the actuator extends axially from said disc-shaped lip contacting portion through the central opening in the closure member. 7. The closure assembly according to claim 4, wherein the biasing member extends between the opposite side of the closure member and an underside of the lip contacting portion in a region surrounding said cooperating connecting elements. 8. The closure assembly according to claim 1, wherein the annular body comprises a radially inwardly protruding shoulder and the closure member has a peripheral seat that is trapped between said shoulder and an upper edge of the cup when the annular body is mounted thereon, to form a seal between said peripheral seat and the upper edge. 9. The closure assembly according to claim 1, wherein said annular body has a threaded connecting portion for cooperation with a corresponding thread adjacent to an upper edge of the cup to mount said annular body on said cup. 10. A non-spill drinking vessel, comprising a cup; anda closure assembly comprising: an annular body mountable to an open upper end of the cup and having a rim to enable a user to drink liquid from said cup through the annular body;a closure member within said annular body positionable so as to extend across the open upper end of the cup to which the annular body is mounted and having a plurality of apertures and a central opening therein;a sealing element positioned on an inner side of the closure member and comprising a socket extending in a first direction from the sealing element and toward the closure member;an actuator positioned on an opposite side of the closure member opposite the inner side and comprising a plug extending in a second direction opposite the first direction from the actuator and toward the closure member which is accessible to the user when said closure assembly is mounted to the cup,wherein the sealing element and the actuator are coupled to each other,wherein a portion of the plug is positioned through the closure member and within the socket, with the sealing element biased into a rest position in which it is urged against said inner side of the closure member, and contacts said inner side with an upper side of the sealing element, which in the rest position runs parallel to the closure member, to block said apertures and prevent the flow of liquid therethrough,wherein the actuator comprises a lip contacting portion that extends over the closure member towards said rim on the annular body, the arrangement being such that the sealing element is moved out of said rest position to allow liquid to flow through said apertures and out of the cup when pressure sufficient to overcome said bias is applied to the lip contacting portion by the user; anda biasing member to bias the sealing element into the rest position, wherein the closure member comprises a deformable diaphragm, wherein the biasing member is integrally formed with said deformable diaphragm, and wherein the deformable diaphragm has a raised region surrounding the central opening that spaces the lip contacting portion from the apertures, said biasing member being formed from said raised region surrounding the central opening, wherein the central opening is formed through the raised region. 11.
