  • Patent number: 4667856
    Abstract: A dispenser for attachment to liquid containers is disclosed which allows a contained liquid to be dispensed by pumping rather than pouring from the container, having a top cylinder containing a pump which is located over a mouth of the container, so that the mouth of the container contacts a gasket of relatively large surface area, and further having a base member pivotally attached to a top cylinder which is pivoted underneath the container to force the mouth of the container against the gasket to provide a seal. The relatively large surface area of the gasket and the design of the base member allow the device to be used with containers of varying size, and the seal achieved thereby allows pump of simple design to be incorporated.
