Abstract
Embodiments of the present invention generally relate to a leak proof drinking cup including a valve assembly and a removable lid with a drinking spout and a vent. The valve assembly includes a drinking valve, a venting valve, or both. When in use, the valve assembly engages with the lid to prevent leaks or spills and to permit the flow of air into the cup. When not in use, the valve assembly disengages from the lid and the valve is open to facilitate proper cleaning of the valve assembly.
Claims19
A leak proof drinking container comprising:
- a container wall defining an enclosure for containing a liquid;
- a drinking aperture sized for passing the liquid from the enclosure;
- a vent aperture sized for passing air in through the container wall as the liquid is removed from the container;
- and a first valve, where:
- the first valve is a drinking valve configured to engage the container wall, the drinking valve having an orifice that is defined by a pair of opposing lips, the pair of opposing lips being configured to:
- (1) be held together when the drinking valve is engaging the container wall to close the orifice, (2) open the drinking valve when engaging the container wall to allow the liquid out of the orifice while suction is applied to the drinking aperture, and (3) be separated from each other to open the orifice when the drinking valve is disengaged from the container.
