US Patent 11247837 Dispenser actuator assembly

A dispenser actuator assembly (100) actuates a dispenser (10). The dispenser (10) is a plastic ampoule (10) having a container (48) having an outer wall (50) and membrane (52) collectively defining a first chamber (54) containing a flowable material (M). The membrane (52) has a weld seam (56). The actuator assembly (100) has a base member (102) configured to mount on the container (48). A fracturing mechanism (116) is operably connected to the base member (102). The fracturing mechanism (116) has a first extending member (132a) and a second extending member (132b), the first extending member (132a) and the second extending member (132b) positioned on the base member (102) in opposed relation. Each extending member (132a,132b) has a projection (150a,150b) positioned proximate the membrane (52). In response to deflection of the extending members (132a,132b) towards one another, the projections (150a,150b) are configured to deflect the outer wall (50) proximate the membrane (52) wherein the weld seam (56) fractures to create an opening through the membrane (56) to allow the flowable material (M) to pass therethrough.
