Kraft - Web page: https://patentgrep.com/patent/US20160257547A1 ## CPC - B67C 11/02: without discharge valves - B67C 2011/30: {comprising venting means} - B67C: CLEANING, FILLING WITH LIQUIDS OR SEMILIQUIDS, OR EMPTYING, OF BOTTLES, JARS, CANS, CASKS, BARRELS, OR SIMILAR CONTAINERS, NOT OTHERWISE PROVIDED FOR; FUNNELS ## Abstract A funnel system for transferring liquids from a dispenser to a receptacle 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. 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. A set of cams are located at preselected points and adapted to mate with a set of collars having threads sized to thread onto a selected receptacle having a threaded inlet and fixedly engage the receptacle inlet. ## Claims ### Claim 1 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; 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 cams are located at preselected points around the band; 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, and each collar 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; and each collar having a set of threads sized to thread onto a selected receptacle having a threaded inlet and fixedly engage the receptacle inlet. ### Claim 2 (depends on 1) The funnel system of claim 1 where the set of cams includes a keyed cam sized larger than the others for alignment purposes. ### Claim 3 (depends on 1) The funnel system of claim 1 where the set of cams comprises at least three cams positioned at predetermined intervals around the band. ### Claim 4 (depends on 1) The funnel system of claim 1 where the set of cams comprises at least three cams positioned at 120° intervals around the band. ### Claim 5 (depends on 1) The funnel system of claim 1 where each collar includes 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. ### Claim 6 (depends on 1) The funnel system of claim 1 where one of the attachment slots is sized differently than the others to accept the keyed cam. ### Claim 7 (depends on 1) The funnel system of claim 1 where the wall tapers to a bottom angled portion inclined obliquely to the upper portion of the wall. ### Claim 8 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. ### Claim 9 (depends on 8) The funnel system of claim 8 where the set of cams comprises at least three cams positioned at 120° intervals around the band. ### Claim 10 (depends on 8) The funnel system of claim 8 where one of the attachment slots is sized differently than the others to accept the keyed cam. ### Claim 11 (depends on 8) The funnel system of claim 8 where the wall tapers to a bottom angled portion inclined obliquely to the upper portion of the wall. ### Claim 12 A kit for 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, 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 cams are located at preselected points around the band, 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; and 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, 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; and each collar having a set of threads sized to thread onto a selected receptacle having a threaded inlet and fixedly engage the receptacle inlet. ### Claim 13 (depends on 12) The kit of claim 12 where the set of cams includes a keyed cam sized larger than the others for alignment purposes. ### Claim 14 (depends on 12) The kit of claim 12 where the set of cams comprises at least three cams positioned at predetermined intervals around the band. ### Claim 15 (depends on 12) The kit of claim 12 where the set of cams comprises at least three cams positioned at 120° intervals around the band. ### Claim 16 (depends on 12) The kit of claim 12 where each collar includes an angled top surface around the circumference of the collar;
