Abstract:
A skin care kit comprising a skin care composition contained within a dispenser wherein the skin care composition comprises:a) an emulsion which comprises:1) at least one hydrophobic phase comprising an oil and from about 0.1% to about 20%, by weight of the composition, of a light emollient;2) at least one hydrophilic phase comprising water; and3) from about 0.1% to about 5%, by weight of the composition, of an emulsifier having an HLB of at least 6;wherein the composition has a viscosity of from about 15,000 cps to about 200,000 cps and a pH of from about 3 to about 9; andb) the dispenser for the skin care composition comprises a container for storing a supply of the skin care composition to be dispensed, said container having a bottom portion and an upper portion, said bottom portion having a slidable follower piston and said upper portion having a pump for dispensing the skin care composition, said pump comprising:1) a first non-return valve (16) provided in an upper partition wall of the container for controlling communication between the interior of the container and a pump chamber through a first opening (12) formed in said partition wall (11);2) a guide sleeve arrangement (6) surrounding said first opening (12) and having first non-return valve (16) pivotally connected thereto, said guide sleeve arrangement extending upwardly from said partition wall to define circumferentially said pump chamber (24), said guide sleeve arrangement (6) having inner and outer circumferential guide sleeves, said first non-return valve being pivotally connected to said inner guide sleeve;3) a cup-shaped actuator cap (7) having a peripheral downwardly projecting outer wall portion and an inner tubular section (19), the latter forming a discharge channel having a laterally outwardly opening outlet passage, wherein:(a) said outer wall portion of the actuator cap (7) is slidably engaged with the outer circumferential guide sleeve of the guide sleeve arrangement (6), both being provided with co-operating stop projections (26, 27) to limit axial upward movement of the actuator cap (7),(b) said outer guide sleeve being integral with said upper partition wall of said container, and providing an upper radially outwardly projecting rim portion (25) spaced from the stop projection (26) of the guide sleeve arrangement (6) to establish a circumferential guide surface engaging an inner guide surface of the outer wall portion of the actuator cap,(c) said tubular section of the actuator cap having a downwardly extending portion having a diameter greater than that of said laterally opening outlet passage and supporting a dispensing piston (22) to keep the piston (22) slidably engaged with said inner circumferential guide sleeve of said guide sleeve arrangement (6), thereby defining a space forming the pump chamber (24),(d) said dispensing piston (22) having a second opening (29) in register with the tubular section of the actuator cap (7),(e) said second opening (29) being controlled by a second non-return valve (3) for controlling communication between the pump chamber upstream thereof and the discharge channel of the actuator cap downstream thereof; and4) a return spring (32) extending between a stationary portion of the inner guide sleeve and the actuator cap (7) to bias said actuator cap (7) into a rest position;wherein said pump is suitable for dispensing per activation an amount of said skin care composition sufficient to provide from about 0.1 mg/cm.sup.2 of skin surface to about 10 mg/cm.sup.2 of skin surface per application.
