Dispenser actuator assembly

A dispenser actuator assembly for actuating a dispenser for dispensing a flowable material, the dispenser in the form of a plastic ampoule assembly having a container having an outer wall and membrane collectively defining a first chamber containing the flowable material, the membrane having a weld seam, the dispenser actuator assembly comprising:

• a base member having an opening configured to mount on the container;
• and
• an actuator assembly operably connected to the base member, the actuator assembly having a flex plate wherein the flex plate is spaced from the base member, the actuator assembly having a first actuator arm and a second actuator arm each connected to opposite ends of the flex plate, the first actuator arm and the second actuator arm extending from the flex plate in generally opposed relation to define a first position, the first actuator arm having a first protrusion depending therefrom and the second actuator arm having a second protrusion depending therefrom, each protrusion positioned proximate the membrane when the base member is configured to be mounted on the container, wherein the first actuator arm and the second actuator arm are pivotable from the first position towards one another to a second position wherein the flex plate flexes wherein the first protrusion is configured to engage the container proximate the membrane and the second protrusion is configured to engage the container proximate the membrane, wherein the weld seam is configured to fracture to create an opening through the membrane configured to allow the flowable material to pass therethrough and from the container.

A dispenser actuator assembly for actuating a dispenser in the form of a glass ampoule assembly having a rupturable glass ampoule containing a flowable material, the glass ampoule contained within an outer container, the outer container having a first open end and a second closed end, the glass ampoule assembly having an applicator positioned in the first open end, the dispenser actuator assembly comprising:

• a base member having an opening configured to mount on the outer container, and
• an actuator assembly operably connected to the base member, the actuator assembly having a flex plate wherein the flex plate is spaced from the base member, the actuator assembly having a first actuator arm and a second actuator arm each connected to opposite ends of the flex plate, the firsts actuator arm and the second actuator arm extending from the flex plate in generally opposed relation to define a first position, the first actuator arm and the second actuator arm extending away from the applicator when the actuator assembly is configured to be mounted on the glass ampoule assembly, each actuator arm having a protrusion positioned proximate the outer container when the base member is configured to be mounted on the outer container, wherein in response to deflection of the actuator arms towards one another to an actuating position, the protrusions are configured to engage the outer container to crush the glass ampoule wherein the flowable material is dispensed from the glass ampoule assembly.

A dispenser actuator assembly for actuating a dispenser in the form of a glass ampoule assembly having a crushable glass ampoule containing a flowable material, the glass ampoule contained within an outer container, the outer container having a first open end and a second closed end, the glass ampoule assembly having an applicator positioned in the first open end, the dispenser actuator assembly comprising:

• a base member having an opening configured to mount on the outer container;
• and
• an actuator assembly connected to the base member by a connector member having a first end connected to the base member and a second end connected to the actuator assembly, the actuator assembly having a flex plate and a first actuator arm and a second actuator arm, the flex plate being spaced from the base member, the flex plate having a central portion having a flex plate opening being generally aligned with the opening of the base member, the first actuator arm connected to a first end of the flex plate and the second actuator arm connected to a second end of the flex plate, the first actuator arm being generally in opposed relation to the second actuator arm, the first actuator arm and the second actuator arm having a first neutral position wherein the flex plate is in generally a planar configuration,
• the first actuator arm having a first protrusion depending therefrom and the second actuator arm having a second protrusion depending therefrom,
• wherein the base member is configured to receive the glass ampoule assembly, wherein the first actuator arm and the second actuator arm are pivotable from the first neutral position towards one another to an actuating position wherein the flex plate flexes wherein the first protrusion is configured to engage the outer container and the second protrusion is configured to engage the outer container to crush the glass ampoule wherein the flowable material is configured to be dispensed from the glass ampoule assembly.

A dispenser and actuator assembly comprising:

• a glass ampoule assembly comprising:
• a rupturable glass ampoule containing a flowable material, the glass ampoule having a first interface area defined generally between a first dome-shaped closed end and a generally cylindrical central portion, the glass ampoule further having a second interface area defined generally between a second dome-shaped closed end and the cylindrical central portion;
• a resilient plastic outer container, the outer container having a first open end and a second closed end, the outer container receiving the glass ampoule through the first open end;
• and
• an applicator positioned in the first open end;
• an actuator assembly comprising:
• a base member mounted on the outer container;
• an actuator assembly having a flex plate operably connected to the base member, the actuator assembly further having a first actuator arm and a second actuator arm each connected to opposite ends of the flex plate, the first actuator arm and the second actuator arm extending from the flex plate in generally opposed relation to define a first position, the first actuator arm and the second actuator arm extending away from the applicator, the first actuator arm having a first protrusion depending therefrom and the second actuator arm having a second protrusion depending therefrom,
• wherein the first actuator arm and the second actuator arm are pivotable from the first position towards one another to a second position wherein the flex plate flexes wherein the first protrusion engages the outer container and the second protrusion engages the outer container to crush the glass ampoule proximate the first interface area wherein the flowable material is dispensed from the glass ampoule assembly.
