Abstract
A closure assembly for a water bottle, having a cap including a mouthpiece that has a first aperture through which water in the bottle can flow out upon the application of suction at the mouthpiece. A support inside the mouthpiece has at least one second aperture that, together with the first aperture, defines a path for water. Also included is a valve member that has a diaphragm located between the mouthpiece and the support. The diaphragm has an aperture in the path and bears resiliently against the support when no suction is applied to the mouthpiece, so its aperture is closed, blocking the path. Upon the application of suction at the mouthpiece, the diaphragm is deformed and moves away from the support so the aperture in the diaphragm is opened to permit the flow of water.
Claims19
A closure assembly for an opening of a drinking vessel, comprising:
- a cap including a hollow mouthpiece protruding from the cap and having a first aperture at a free end of the mouthpiece through which liquid in the vessel can flow out upon application of suction to the mouthpiece;
- a support located inside the mouthpiece and having at least one second aperture that, in conjunction with the first aperture, defines a path for flow of the liquid out of the vessel;
- and
- a valve member comprising a resiliently deformable diaphragm located between the mouthpiece and the support, the diaphragm having a third aperture in the path and normally bearing resiliently against the support to close the third aperture with the support and to close the second aperture with the diaphragm, thereby blocking the path, wherein, upon the application of suction at the mouthpiece, the diaphragm is deformed and moves away from the support so that the second and third apertures are opened to permit the flow of the liquid out of the vessel.
A closure assembly for an opening of a drinking vessel, comprising:
- a cap having a hollow mouthpiece protruding from the cap and having a first aperture at a free end of the mouthpiece through which liquid in the vessel can flow out upon application of suction to the mouthpiece;
- a generally tubular support located inside the mouthpiece and having an end including at least one second aperture that, in conjunction with the first aperture, defines a path for flow of the liquid out of the vessel;
- and
- a generally tubular valve member comprising a sleeve mounted on the support, between the support and the mouthpiece, and having a resiliently deformable diaphragm at one end, the diaphragm being located between the mouthpiece and the support and having a third aperture in the path, the diaphragm normally bearing resiliently against the support to close the third aperture with the support and to close the second aperture with the diaphragm, thereby blocking the path, wherein, upon the application of suction at the mouthpiece, the diaphragm is deformed and moves away from the support so that the second and third aperture s are open to permit the flow of the liquid out of the vessel.
