A cap for use with a dispensing system. The cap includes a main outer cap and an inner cap. The main outer cap has a central sleeve which receives and seals against a probe. The inner cap moves into and out of a sealing engagement with the central tube as the bottle is raised and lowered over the probe. The seal between the inner cap and the central tube is located on the outside surface of the central tube. The location of the connection between the inner cap and the probe is displaced away from the location of the connection between the inner cap and the sleeve of the main outer cap. This allows the cap to have effective differentials between the forces which are necessary to achieve proper sequencing of the formation of the various seals and connections which occur during use of the cap.
A cap for seal a container, said cap comprising an outer cap and an inner cap, said outer cap comprising a cylindrical skirt with at least one container gripping formation on an inside surface of said skirt for engaging a corresponding formation on a neck of said container, a tube generally cylindrical in shape and generally parallel to and concentric with said skirt, said tube and said skirt being joined by an annular base, said annular base surrounding an axial passageway extending through said base and through said tube, said inner cap comprising a sealing sleeve, said sealing sleeve fitting over and sealing against an outside surface of said tube, and a second sleeve adapted to engage a probe and hold said inner cap in a position adjacent to said probe.
A closure and probe combination for dispensing flowable substances from a container, said combination including a probe used to remove contents of said container and a closure comprising an outer cap and an inner cap, said outer cap comprising a cylindrical skirt with a container gripping formation on an inside surface of said skirt for engaging a corresponding formation on an outside surface of a neck of said container, a tube generally cylindrical in shape and generally parallel to and concentric with said skirt, said tube and said skirt being joined by an annular base, said annular base surrounding an axial passageway extending through said base and through said tube, said inner cap comprising a sealing sleeve, said sealing sleeve fitting over and sealing against an outside surface of said tube, and a second sleeve in said inner cap which engages and retains said inner cap in a position adjacent to said probe.
A cap for sealing a container, said cap comprising an outer cap and an inner cap, said outer cap comprising a cylindrical skirt with at least one gripping formation on an inside surface of said skirt for engaging a corresponding formation on the neck of a container, a tube generally parallel to and concentric with said skirt, said tube and said skirt being joined by an annular base, said annular base surrounding an axial passageway extending through said base and through said tube, said inner cap comprising two generally concentric sleeves, a first sealing sleeve and a second probe-engaging sleeve, said first sealing sleeve fitting over sealing against an outside surface of said tube, and said second sleeve having at least one probe engaging formation useable to hold said inner cap in a position adjacent to a free end of said probe, said first sealing sleeve and said second probe-engaging sleeve having differing transverse dimensions, one end of said second sleeve having a closed end and defining a recess for receiving a tip of a probe, and said sealing sleeve defining a second recess axially offset with respect to said first recess and shaped to receive a free end of said tube.
