Claims34
A dispensing and applicator system for applying a plurality of dermatological agents comprising:
- (a) a first and second flexible, moisture impermeable cover sheet;
- (b) a first applicator pad and a second applicator pad affixed to a first surface of said first and second cover sheets, respectively;
- said first pad being impregnated with a first composition comprising a first dermatological agent and said second pad being impregnated with a second composition comprising a second dermatological agent;
- and
- (c) a flexible, moisture impermeable support sheet having a peripheral surface of its first side releasably sealed by means of a first continuous seal line to an opposed peripheral surface of the first surface of the first cover sheet so as to form a first compartment containing the first pad attached to said surface of first cover sheet;
- and having a peripheral surface of said support sheet releasably sealed by means of a second continuous seal line to an opposed peripheral surface of the first surface of the second cover sheet so as to form a second compartment containing said second pad attached to said second cover sheet, which seal lines are positioned inwardly from the edges of the sheets over a portion of the opposed peripheral surfaces, so as to form two pairs of opposed flanges;
- each pair of opposed flanges being separable to at least partially release each cover sheet from the support sheet, so that said first pad and said second pad are exposed.

- (a) a first and second flexible, moisture impermeable cover sheet;
- (b) a first and second applicator pad each affixed to a first surface of said first and second cover sheets, respectively;
- said first pad being impregnated with a first composition comprising a first dermatological agent and said second pad being impregnated with a second composition comprising a second dermatological agent;
- and
- (c) a flexible, moisture impermeable support sheet having a peripheral surface of its first side releasably sealed to an opposed peripheral surface of the first surface of the first cover sheet by a first continuous seal line, so as to form a first compartment containing the first pad attached to said first surface of the first cover sheet;
- and said second cover sheet having a peripheral surface of said support sheet releasably sealed to an opposed second peripheral surface of the first surface of the second cover sheet by means of a second continuous seal line, so as to form a second compartment containing said second pad attached to the first surface of said second cover sheet, which seal lines are positioned inwardly from the edges of the sheets over a portion of the opposed peripheral surfaces, so as to form two pairs of opposed flanges;
- each of the pairs of flanges being separable to first release the second cover sheet from the first cover sheet, and then to release the first cover sheet from the support sheet, so that said pads are exposed.
