Abstract
A device 560, for administering multiple single doses of a medicated cream, includes a cartridge 562 having a barrel 564 for containing the cream, a plunger 608 for moving the cream from within the cartridge, and a stem 610 for moving the plunger within the cartridge. A carrier 612 is formed with a cartridge-receiving nest 712 for receiving the barrel 564. A plurality of spaced, transaxial grooves 726, 728, 730 and 732 are formed in the carrier 612 for receiving a flange 572 of the cartridge 562 during the dispensing of multiple, successive, single doses of the cream. The carrier 612 is formed with a pair of resilient ears 750 and 752 and a passage 738 for removably retaining the stem 610 with the carrier while allowing axial movement of the stem.
