International Classification:

B67D 522

US Classification:

222 43

Abstract:

An improved liquid dispenser has two concentrically spaced cylinders with a pump plunger fitting the inner cylinder, an inlet check valve at the bottom of the outer cylinder, and an outlet check valve adjacent the top of the outer cylinder with a graduated stem extending upwardly from the plunger through a cap structure adapted to engage the open top of a liquid container. The pump plunger is restrained from moving upwardly out of the inner cylinder and a collar is adjustably mounted on the stem above the cap for setting the pump stroke as indicated by the graduations on the stem to thus provide a dispenser adapted to fit containers having a small opening therein.

Inventors:

John J. Trujillo - Castro Valley CA

International Classification:

B67D 522

US Classification:

222 43

Abstract:

A liquid dispenser adapted to fit over the open top of a container has a pump plunger connected by valving between a depending inlet and an outlet for pumping liquid from the container and a limitedly movable gauge rod is disposed in spaced parallel relation to the plunger with means securing the plunger and rod together in adjustable longitudinal relation to thereby adjustably fix the plunger stroke for metering fluid dispensed per stroke of the plunger.
