Abstract
Abstract A dispensing apparatus comprising a container and a pump housing carrying a pressure bulb which, when compressed, effects the discharge of a metered quantity of the product to be dispensed through the positive pressure arising in the pressure bulb at this compression and whereby two valves, arranged in the pump housing are displaced. The pump housing is arranged in a narrow portion or neck of the container which neck has a swelling forming the pressure bulb. The container with its neck and pressure bulb are formed in one piece from non-rigid plastic or rubber materials.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
256 words
A dispensing apparatus for discharging a fluid product comprising a container for said fluid product, said container having an elongated neck portion formed integrally therewith, said neck portion having a generally cylindrical configuration with an enlargement protruding outwardly therefrom to define a pressure bulb, said container, neck portion and pressure bulb being made in one piece from a flexible material, a pump housing disposed in said elongated neck portion, said pump housing having an internal central passage having one longitudinal end in communication with said container and the other longitudinal end defining a discharge end, a first and second valve means disposed in spaced relationship to one another in said central passage to define therebetween an intermediate valve chamber, said first valve being located between said container and said intermediate valve chamber, said second valve being located between said intermediate valve chamber and said discharge end, said pump housing having an opening providing communication between said intermediate valve chamber and the interior of said pressure bulb, said pressure bulb being compressible to close said first valve and open said second valve as fluid is forced out of the interior of the pressure bulb, through said pump housing opening and through said pump central passage to said discharge end, said pressure bulb being returnable to its uncompressed state to open said first valve and close said second valve as fluid is drawn from said container past said first valve, into said intermediate valve chamber, through said pump housing opening and into the interior of said pressure bulb.
