US 11,241,709 B1 · Dispenser actuator assembly

Abstract

A dispenser actuator assembly (100) has base member (102) and an actuator arm (104) that is configured to crush a glass ampoule assembly (10). The glass ampoule assembly (10) has a rupturable glass ampoule (12) containing a flowable material (M). The glass ampoule (12) is contained within an outer container (14), the outer container (14) having a first open end (22) and a second closed end (24). The glass ampoule assembly (10) has an applicator (16) positioned in the first open end (22). The dispenser actuator assembly (100) has the base member (102) that is configured to mount on the outer container (14). The actuator arm (104) is pivotally connected to the base member (102). The actuator arm (104) is pivotable from a first position to a second position that is configured to engage the outer container (14) to crush the glass ampoule (12) wherein the flowable material (M) is dispensed from the glass ampoule assembly (10).
