ABSTRACT:
A fluid applicating apparatus is provided for use with a cartridge 10 having a self-sealing, penetrable membrane 16 and an inner volume containing fluid to be dispensed. The applicating apparatus includes an applicator 48 located at one end of an elongated body 20, the applicator being formed of a porous, compressible material. The flow of fluid between the inner volume of the cartridge 10 and the applicator 48 is controlled by providing a penetrating member 34 movable between a first position in which it penetrates the membrane 16 and permits fluid communication between the inner volume and the applicator 48 and a second position in which it is extracted from the inner volume. The membrane 16 seals off the inner volume upon removal of the penetrating member such that fluid does not leak from the inner volume when the penetrating member is withdrawn.
