Abstract
In some embodiments, a dispenser for attachment to a liquid container may include one or more of the following features: (a) a tubular valve body of a generally hollow form having a liquid outlet port on one end of the valve body capable of coupling to the liquid container, the valve body further including an air vent opening and a liquid vent opening located on an opposite side of the valve body, (b) an integral lid with the valve body slidingly disposed on the opposite side of the valve body and coupled to be moved between a liquid blocking and a liquid dispensing position, and (c) a liquid seal coupled to the integral lid capable of positioning within a liquid vent opening and an air seal coupled to the integral lid capable of positioning within an air vent opening.
Claims20
A dispenser for attachment to a liquid container comprising:
- (a) a valve body of a generally hollow form having a liquid inlet port on one end of the valve body for coupling to the liquid container, the valve body further including an air vent opening and a liquid vent opening, the air vent opening and liquid vent opening located on an opposite side of the valve body from the inlet port;
- (b) a lid, the lid and valve body formed of a single piece of material, the lid movable between a liquid blocking and a liquid dispensing position;
- (c) a liquid seal coupled to the lid and positionable within the liquid vent opening and an air seal coupled to the lid and positionable within the air vent opening;
- (d) a collapsible dome member coupled to the valve body adjacent to the lid, the collapsible dome member deformable between a compressed and an expanded state.
A dispenser, comprising:
- (a) a generally cylindrical valve body having a liquid inlet end and an opposite end, the opposite end having a liquid outlet port and an air vent opening;
- (b) a lid, the lid and valve body formed of a single piece of material, the lid movable between a liquid blocking and a liquid dispensing position;
- (c) a liquid seal and an air seal, the liquid seal coupled to the lid and positionable within the liquid outlet port, the air seal coupled to the lid and positionable within an air vent opening;
- and
- (d) a collapsible dome member coupled to the valve body adjacent to the lid.
A dispenser, comprising:
- (a) a valve body having a liquid inlet port on one end of the valve body and an air vent opening and liquid vent opening located on an opposite side of the valve body;
- (b) a lid hingedly attached to the valve body, the lid and valve body formed of a single piece of material, the lid movable between a liquid blocking and a liquid dispensing position;
- (c) a liquid seal and an air seal coupled to the lid, the liquid seal positionable within the liquid vent opening and the air seal positionable within the air vent opening;
- (d) a collapsible dome member coupled to the valve body adjacent to the lid, the collapsible dome member formed from a polymeric material and being deformable between a compressed and an expanded state.
