ABSTRACT:
A filtering device includes a head intended to be permanently installed in a fluid dispensing machine and a disposable canister therefor. A central chamber is formed in the head which chamber is in communication with an inlet port and an outlet port for receiving an unfiltered liquid and supplying a filtered liquid, respectively. The disposable canister has a flask shaped main body with a flat top and a neck of substantially uniform diameter on the top. The neck fits in the central chamber. A tube extending through the neck defines an annular clearance between the tube and the interior of the neck which annular clearance is in fluid communication with the inlet port. The opening into the tube located at the top of the neck is in fluid communication with the outlet port in the head. A pair of tab receptacles on the head and a complementary pair of tabs on the canister are engageable with one another by 1/4 rotation of the canister to lock the canister to the head.
