Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
In combination with a pump for dispensing liquid from a container, the pump being adapted for actuation by vertical depression of a push button on the plunger and having a spray nozzle associated with the push button for directing laterally the dispensed liquid, pump actuating means comprising an annular base adapted for securement on the top of a container closure member, a trigger mounting post projecting upwardly from the base, an elongated trigger having one end hinged to the top of the post, an intermediate portion bifurcated to pass either side of the push button and nozzle and the other end extending downward below the nozzle to constitute a finger piece, and a saddle having a bridge portion resting on the push button and side portions each connecting one end of the saddle to one side of the bifurcated trigger portion by at least one flexible connection point, permitting said side portions to rock relatively to the trigger in the vertical plane of movement of the trigger, whereby depression of the trigger pulls the push button downward.
Claim 2
Dependent Claim
