1. A self closing tap comprising a cartridge and a tap handle interface, in which the cartridge comprises a piston, and a plunger in which
the piston is comprised of a piston head, and a piston shaft,
the piston shaft has a longitudinal axis and is fixed to the piston head at a first end, and the second end of the piston shaft is an engagement end,
the plunger is movably fixed to a first portion of the piston shaft and adapted to move such that the plunger moves longitudinally along the first portion of the piston shaft,
the plunger has a first and second end with the second end of the plunger being closer to the engagement end of the piston shaft than the first end,
the tap handle interface comprises a first and second recess,
the first recess is adapted such that the first recess receives the engagement end of the piston shaft and prevents rotation of the piston shaft around its longitudinal axis, and the second recess is adapted such that the second recess receives at least the second end of the plunger and prevents rotation of the plunger around the piston shaft.
