Abstract
Abstract A trigger-like actuating element for association with a pump having a depressable piston or plunger for dispensing small metered quantities of a liquid from a container such as a jar, bottle or can, the trigger-like element being designed to be manually operated for substantially horizontal movement to thereby depress vertically the pump piston or plunger in order to deliver a quantity of liquid, usually as a spray, in a horizontal direction.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
207 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 nozzle spaced from the axis of the plunger at the end of an elongated lateral extension of the push button for directing laterally the dispensed liquid, the pump further being provided with a collar element adapted to bear against the top surface of a container cap, pump actuating means comprising an annular base adapted to be held in place between said collar element and said top surface for securement of said means on the top of the container closure member, trigger support means projecting upward from the base and a trigger pivotally connected to the support means, the trigger having a body portion provided with a chamber adapted to contain a portion of the push button extension, said chamber having a lateral opening through which the nozzle end of the extension can project, and a finger piece projecting downwardly below the nozzle, the trigger body portion and push button extension being provided with cooperating parts adapted for sliding engagement to depress the plunger when the finger piece is pulled to rotate the trigger about its pivotal connection.
