Fluid application device and method

An applicator device for applying a fluid, comprising:

• an elongate hollow body comprising an outer wall having an inner surface, the hollow body having a proximal end and a distal end;
• a base at the distal end of the hollow body;
• an applicator pad coupled to the base;
• and
• an actuator sleeve having a proximal end, a distal end, and an outer wall having an outer surface, the actuator sleeve being configured to be inserted within the hollow body such that the outer surface of the outer wall of the actuator sleeve is disposed within the inner surface of the outer wall of the hollow body, the actuator sleeve being configured to be actuated to release the fluid to the applicator pad from a container configured to be inserted into the hollow body;
• wherein the actuator sleeve includes at least one notch extending from the distal end of the actuator sleeve toward the proximal end of the actuator sleeve;
• and
• wherein the notch is configured to interact with a corresponding outward protrusion on the container.

A system for applying a fluid, comprising:

• a container configured to contain the fluid;
• and
• an applicator device for applying the fluid, said device comprising:
• an elongate hollow body having a proximal end and a distal end, the hollow body being configured to have the container inserted therein;
• a base at the distal end of the elongate hollow body;
• an applicator pad configured to be coupled to the base;
• and
• an actuator sleeve having a proximal end and a distal end configured to be installed within the hollow body between an inner surface of an outer wall of the hollow body and an outer wall of the container such that longitudinal translation of the actuator sleeve within the hollow body releases the fluid from the container, allowing the fluid to flow to the applicator pad;
• wherein the actuator sleeve includes one or more longitudinal projections projecting distally and configured to interact with a cap portion on a distal end of the container to remove the cap portion from the container to release the fluid from the container.

• a base at the distal end of the elongate hollow body;
• and
• an actuator sleeve having a proximal end and a distal end configured to be installed within the hollow body between an inner surface of an outer wall of the hollow body and an outer wall of the container such that longitudinal translation of the actuator sleeve within the hollow body releases the fluid from the container, allowing the fluid to flow to the applicator pad;
• wherein the container includes a flat side;
• and
• wherein the actuator sleeve includes a thicker, reinforced portion, which corresponds with the flat side of the container.

• and
• an applicator device for applying the fluid, said device comprising:
• an elongate hollow body having a proximal end and a distal end, the hollow body being configured to have the container inserted therein;
• a base at the distal end of the elongate hollow body;
• an actuator sleeve having a proximal end and a distal end configured to be installed within the hollow body between an inner surface of an outer wall of the hollow body and an outer wall of the container such that longitudinal translation of the actuator sleeve within the hollow body causes the actuator sleeve to act upon the container to release the fluid from the container, allowing the fluid to flow to the applicator pad;
• wherein the container includes:
• a main body portion;
• a cap portion;
• and
• a neck portion between the main body portion and the cap portion, the neck portion comprising:
• a frangible portion;
• and
• a hinge element disposed opposite the frangible portion and configured to maintain a connection between the main body portion and the cap portion after the frangible portion fractures, thus allowing the cap portion to flip open.
