发明名称 Liquid product dispenser
摘要 The present invention provides a hand dispenser for a liquid product that includes a resilient closed container mounted upon a base. The container, which has a discharge port connected to a dispensing orifice for the liquid product, is movable between a first position, which closes the discharge port and makes the dispenser adapted for traveling, shipment, and the like. The container also has a second position, which opens the discharge port and places the dispenser in the dispensing mode. The dispenser, when in the dispensing mode, is manually operated by squeezing the container, which dispenses a portion of the liquid product; upon return of the resilient container to its original shape, the level of the liquid drops, and a lesser pressure is created in the air pocket over the liquid product, thus causing atmospheric air to press back any movement of liquid product toward the dispensing orifice.
