Abstract

A marking instrument for applying a fluid, said instrument comprising a main body having a replaceable cartridge receiving location and a cannula for puncturing a cartridge received at said location; a cartridge having a re-sealable diaphragm, said diaphragm allowing repeated puncture and sealing by said cannula, said cartridge further having a deformable wall portion; wherein said cartridge is biassed away from a puncturing position, movement into the puncturing position causing deformation of the deformable wall portion to thereby reduce the internal volume of the cartridge. In this regard, the reduction in the internal volume of the cartridge results in the pressure therein being increased, which will urge fluid contained in the cartridge to flow through the punctured resealable diaphragm.
