Dispenser assembly

摘要

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.

主权项

1. A fluid dispensing valve assembly comprising:
a housing, the housing having a liquid inlet side and a liquid outlet side and defining a fluid dispensing port and a vent opening; a flap hingedly and integrally attached to the housing and disposed on the liquid outlet side, the flap having an actuator extending therefrom, the flap extending over the fluid dispensing port and vent opening; and an elastically deformable dome member movable between a collapsed configuration and an expanded configuration, wherein the actuator contacts the elastically deformable dome member; wherein the fluid dispensing valve assembly defines a fluid outlet flow path when the deformable dome member is in the collapsed configuration and wherein the fluid dispensing valve assembly comprises a liquid seal, the liquid seal being the only liquid seal in the fluid outlet flow path, the liquid seal sealing the fluid dispensing port when the elastically deformable dome member is in the expanded configuration, wherein at least a portion of the liquid seal is disposed on the liquid inlet side.
