Abstract
A liquid dispenser is mountable to a container having an interior portion. The liquid dispenser includes a pump and a pressurization tube that includes a first end connected to the pump, a second end in fluid communication with the container interior, and a pressure release aperture. The dispenser further includes a valve that is located in the housing and includes a first port in fluid communication with an outside area, a second port in fluid communication with the pressure relief aperture, and a third port in fluid communication with the interior cavity of the housing. The valve further includes a plug selectively movable between a first position, in which the plug blocks the third port, and a second position, in which the plug blocks the second port.

A liquid dispenser mountable to a container having an interior portion, the liquid dispenser comprising:
- a housing defining an interior cavity;
- a pump;
- a pressurization tube having a first end configured to receive pressurized air from the pump, a second end in fluid communication with the interior portion of the container, and a pressure relief aperture extending through a wall of the pressurization tube between the first end and the second end;
- and
- a valve disposed within the interior cavity of the housing, the valve comprising a first port in fluid communication with an area exterior the housing, a second port in fluid communication with the pressure relief aperture, a third port in fluid communication with the interior cavity of the housing;
- and a plug selectively movable between a first position, in which the plug blocks the third port, and a second position, in which the plug blocks the second port, wherein the first port is in fluid communication with the second port when the plug is in the first position, and the first port is in fluid communication with the third port when the plug is in the second position.
A liquid dispenser mountable to a neck of a bottle to sealingly engage a mouth of the bottle, the liquid dispenser comprising:
- a housing;
- a pump disposed within the housing and having an outlet;
- a pressurization tube having a first aperture in fluid communication with the pump outlet, a second aperture in fluid communication with an interior of the bottle, and a third aperture;
- and
- a valve disposed within the housing, the valve comprising a first port in fluid communication with an area outside of the housing, a second port in fluid communication with the third aperture of the pressurization tube, a third port in fluid communication with an interior cavity formed in the housing;
- and a plug selectively movable between a first position, in which the plug blocks the third port, and a second position, in which the plug blocks the second port, wherein the first port is in fluid communication with the second port when the plug is in the first position, and the first port is in fluid communication with the third port when the plug is in the second position.
