Abstract:
An actuator with overmold assembly, comprising:(a) a post carried within the actuator assembly, the post having a side wall and post face; (b) and at a predetermined distance below, a frustrum shoulder, all on the same axis; (c) a flexible diaphragm fitment inner half, disposed over the post, the flexible diaphragm fitment inner half, having a flexible diaphragm fitment inner side wall and flexible diaphragm fitment inner half face; (d) wherein the flexible diaphragm fitment inner half, has a first position in which the flexible diaphragm fitment inner half, side wall sealibly contacts the actuator post side wall and the flexible diaphragm fitment inner half, face sealibly contacts at least a portion of the actuator post face; having a outlet orifice, which seals in a biased relationship against a portion of the said post, at a central location on its face; (e) wherein the flexible diaphragm fitment inner half, has a second position in which the flexible diaphragm fitment inner half, side wall flexes away from the actuator post side wall, and flexible diaphragm fitment inner half, face flexes away from at least a portion of the actuator post face, at the said central location on its face; (f) wherein the assembly and in combination with the flexible diaphragm fitment inner half, there is a compression fitment outer half, which is overmolded as a laminated and bonded part that makes the combination into a unitary piece that is molded in two different materials, the flexible diaphragm fitment inner half and the compression fitment outer half which becomes a laminate bond and the second stage of the unitary piece which is disposed about the flexible diaphragm fitment inner half, side wall, the compression outer fitment arrests the flex of the flexible diaphragm fitment inner half, side wall at a predetermined distance away from the actuator post side wall and retains the unitary piece in the actuator assembly in proper functional relationship.
