Claims15
A dispensing device comprising:
- a container;
- a first liquid dermatological agent in the container;
- and
- a porous applicator partially inserted in an opening at a top end of the container such that the porous applicator has a top surface that extends past the top end of the container, wherein:
- the porous applicator is saturated with a second liquid comprising a second dermatological agent;
- the porous applicator comprises an injection-molded polyethylene body having open-celled pores, wherein the open-celled pores extend from a bottom of the porous applicator to a top surface of the porous applicator, wherein the open-celled pores are filled with the second dermatological agent such that the pores deliver the second dermatological agent to the top surface of the porous applicator by capillary action without externally-applied pressure;
- and
- the porous applicator defines a channel from a bottom surface of the porous applicator to the top surface of the porous applicator, such that the first dermatological agent can flow through the channel in the porous applicator over the top surface of the porous applicator.
