Funnel System with Interchangeable Collars

A funnel system for transferring liquids from a dispenser to a receptacle, the funnel system comprising:

• a funnel including a mouth end and a smaller outlet end the funnel formed as a hollow conical portion with an angled wall having a rim around the mouth end, the outlet end is perpendicular to a central axis running vertically through the center of the funnel, where the wall tapers to a bottom angled portion inclined obliquely to the upper portion of the wall;
• a vent channel runs through the interior of the wall to a vent opening inside the hollow conical portion, where the vent channel includes an inlet port;
• the angled wall terminates above the outlet end in a band having a bottom surface parallel to the funnel outlet;
• a set of at least three cams are located at preselected points around the band where the set of at least three cams includes a keyed cam sized larger than the others for alignment purposes;
• the bottom surface of the band is offset above the outlet end;
• the wall tapers to a bottom angled portion between the band and the outlet end;
• a set of collars adapted to mate with the funnel outlet, each collar including a collar opening sized to match the outlet of the funnel, each including a set of cam attachment slots adapted to receive the set of cams, wherein at least one of the collars includes a venting port located to be aligned with the vent channel inlet port when the funnel is fixed into a collar and offset to be in fluid communication with a receptacle;
• where each collar includes
• a collar opening sized to match the outlet of the funnel,
• an angled top surface around the circumference of the collar;
• the set of cam attachment slots are located around the angled top surface so as to accept the set of cams;
• a seating bezel surrounding the opening;
• where, juxtaposed between the seating bezel and the angled top surface is a ring having a flat surface adapted for seating the funnel band;
• and
• each collar has a set of threads sized to thread onto a selected receptacle having a threaded inlet and fixedly engage the receptacle inlet.
