DEFINITION

Classification: 401/185

(under subclass 184) Implement wherein the elastic wall forms a hollow chamber extending from and in communication with the reservoir and is of such shape as to present opposing elastic wall elements which may be deformed in a direction toward one another.

(1) Note. A squeeze bulb is recognized as an elastic wall of a reservoir when in continuous communication therewith or, if valved, capable of two-way communication. A patent for an implement having a squeeze bulb communicating with a reservoir through a one-way valve which permits only the entry of pressurizing gas into, or only removal of gas from, the reservoir will be placed in subclasses 188 or 189, respectively.

SEE OR SEARCH THIS CLASS, SUBCLASS:

184, for an implement whose manually engageable, elastic wall portion is curved but no more than hemispherical in shape so that no opposed portions are available for engagement and deformation toward one another.
