Embodiment Construction

[0209] First refer to Figure 1a , which shows an applicator 1 having an applicator head 5 with a smooth, raised metal applicator face 51 with a central hole 153 . The aperture 153 is sealed by an elastomeric slit valve 71 on the barrel (not shown). With the cartridge inserted, the applicator face 51 is enlarged compared to the diameter of the applicator head 5 . The shoulder portion 55 behind the applicator face 51 provides a resting surface against which the user applies fingertip pressure when using the applicator, and which also protects the user's fingers from Contact is made with the medicament in the replaceable cartridge as the medicament is dispensed through the slit valve 71 onto the applicator face 51 .

[0210] The cartridge is enclosed in a housing 40 which is assembled with the applicator head 5 . The dial knob 30 is attached to the housing 40 and can be accessed from Figure 1a The illustrated decoupled position is moved in which the knob is free to rotate wit...

Abstract

An applicator for topically applying a semi-solid medicament comprises an applicator head having an applicator face for spreading medicament across the skin; a sealable aperture on the applicator face; and a drive mechanism for forcing medicament out through the aperture. The applicator head includes a cartridge port at the rear of the applicator face for receiving a dispensing end of a cartridge charged with medicament. The drive mechanism comprises a dial knob rotatable around a longitudinal axis of the applicator for advancing a piston along a drive member towards the applicator head to force medicament from the cartridge and thereby dispense a predetermined dose of medicament onto the applicator face.

technical field [0001] The present invention relates to an applicator for applying a pharmaceutical preparation to the skin, in particular eg to the skin of a person suffering from psoriasis. More specifically, the present invention relates to an applicator for use with a replacement medicament cartridge, and to a cartridge for use with said applicator. Background technique [0002] Psoriasis occurs when the normal cycle of replacing skin cells is accelerated. Although psoriasis exists as a skin disease in its own right, in recent years it has been established that psoriasis has its roots in the immune system. Normally, skin cells take about 21 to 28 days to replace themselves, but in people with psoriasis skin cells can be replaced as quickly as every 2 to 6 days. This acceleration leads to a buildup of skin cells on the surface of the skin, often referred to as psoriatic plaques. [0003] Patches or plaques of psoriasis can appear more or less anywhere on the body, but ...
