Abstract
An applicator includes a puncture protrusion disposed on an inner surface of an internal chamber of a handle of the applicator. The puncture protrusion is configured to puncture an end surface of a cartridge within the internal chamber, which cartridge contains a liquid that is resultantly allowed to flow through a passageway in the puncture protrusion toward an applicator pad for application onto a surface. Puncturing is achieved in response to rotation of an advancer including a pinion portion that tangentially engages a surface of the cartridge, which rotation is translated to longitudinal advancement of the cartridge toward the puncture protrusion.
