Claims9
A dispensing device comprising:
- a plastic bag containing a liquid dermatological agent, wherein the plastic bag comprises a closed distal end and an opening at a proximate end;
- and
- a porous applicator inserted into the opening at the proximate end of the plastic bag such that:
- the porous applicator has an upper portion that extends past a top of the proximate end of the plastic bag;
- the porous applicator comprises an injection-molded polyethylene body having open-celled pores;
- the open-celled pores extend from a bottom of the porous applicator to a top surface of the porous applicator;
- the porous applicator draws the liquid dermatological agent in the plastic bag such that the open-celled pores are filled with the liquid dermatological agent such that the pores deliver the liquid dermatological agent to a top surface of the porous applicator by capillary action;
- and
- the porous applicator substantially fills the opening at the proximate end of the plastic bag such that the liquid dermatological agent is prevented from free-flowing out of the plastic bag.
