Title:
PUMPING DEVICE FOR LIQUID STORAGE VESSEL
Document Type and Number:
WIPO Patent Application WO/2010/050772
Kind Code:
A2
Abstract:
This invention relates to a pumping device for a liquid storage vessel having a pump head. This device discharges the contents only when the pump head is pushed down. When the pump head rises, a protrusion of a discharge-guiding member deforms a hooking piece, and is directly in contact with the outer circumference of the discharge-guiding member to seal the internal space of the pumping device. In addition, when the pump head is moved up and down, an opening and closing member and an exhaust valve block inflow of outside air and the discharge of contents through the opening and closing of the head valve and the discharge-guiding member if the vessel stands upside down. Thereby, the contents are protected from corrosion, contamination, and deterioration.
