Patent ID: 7225948

Claim:
A dispenser for dispensing fluid comprising: a housing, a removable container insertable into the housing to assume a dispensing position and removable from the housing for replacement, the container carrying a pump having a piston reciprocally slidable along an axis for dispensing fluid from the container with reciprocal axial sliding of the piston, the piston rotatable about the axis, a directional nozzle carried on the piston wherein the piston in desired relative rotational positions about the axis directs fluid from the nozzle over desired angular sectors and in undesired rotational position directs fluid from the nozzle over undesired angular sectors, cam surfaces carried on the piston, camming surfaces carried on the housing, wherein on insertion of the container carrying the pump and its piston into the housing, the cam surfaces and camming surfaces engage to rotate the piston about the axis from undesired rotational positions to desired rotational positions.
