A lid assembly including a lower lid, a plug element movable relative to the lower lid between a plugged position and an unplugged position, and an upper lid rotatably movable relative to the lower lid between an open position in which the plug element is in the unplugged position and a closed position in which the plug element is in the plugged position. The lid assembly further includes a rotational interface adapted to couple the upper lid to the lower lid, the rotational interface including a resilient cleat, a ledge, and a backstop. One of the lower lid and upper lid includes the resilient cleat and an other of the lower lid and upper lid includes the ledge. The resilient cleat engages the ledge to secure the upper lid in rotational engagement with the lower lid. The backstop is positioned to inhibit disengagement of the resilient cleat from the ledge.

A solution is proposed for closing a mouth (125) of a container (110) of a liquid (105). A corresponding closure (135) comprises a cap (205) having fixing means (318) for fixing the cap (205) to the container (110), the cap (205) being rotatable around a longitudinal axis (203) of the container (110) in a fixed condition wherein the closure (135) is fixed to the container (110), a delivery port (336) for delivering the liquid (105) from the container (110), a cap suction conduit (345) for suctioning air into the container (110) during the delivering of the liquid (105) and a connector (342) for connecting a delivery device (805) of the liquid (105), the connector (342) being in fluid communication with the delivery port (336), a cursor (210) having a thread (406) for screwing the cursor (205) with respect to the container (110), a valve member (424) in a closed position wherein the valve member (215) closes the delivery port (336), and a cursor suction conduit (433) slidebly coupled with the cap suction conduit (345), a frangible element (351) closing the cap suction conduit (345) or the cursor suction conduit (433), and dragging means (327, 409) for dragging the cursor (210) into rotation by the cap (205), wherein the closure (135) is configured to cause the cursor (210) to slide with respect to the cap (205) in response to at least one rotation of the cap (205) thereby moving the cursor suction conduit (433) to break the frangible element (351), putting in fluid communication the cursor suction conduit (433) with the cap suction conduit (345), and moving the valve member (424) to an open position, wherein the valve member (215) opens the delivery port (336).

A system and method for dispensing fluids is introduced. A preferred embodiment comprises a sealed tank, a bag containing fluid inside the sealed tank, an outlet for dispensing the liquid in the bag, and a pressure generating device to create pressure in the sealed tank.

An additive delivery system may incorporate a cartridge system, including a container cap and a reservoir assembly that provides for storage of an additive. The container cap includes a mixing nozzle for mixing of the additive with a base fluid as the base fluid flows from the base fluid container through the cartridge. A one-way valve prevents backflow of base fluid and/or mixed base fluid/additive from an area downstream of the mixing nozzle such that the base fluid supply remains in a pure state.

A measuring a closed-loop fluid transfer system is provided that includes a measuring adapter having a first end and a second ends, and a chamber located there between and configured to hold a volume of fluid. The measuring adapter includes a first receiving valve assembly located at the first end of the measuring adapter. The first receiving valve assembly includes a receiving valve member, at least a portion of which is separable from a portion of the first receiving valve assembly. This creates an opening that provides fluid communication to the chamber when a force is exerted on the receiving valve member of the first receiving valve assembly. A second valve assembly located at the second end of the measuring adapter includes a valve member. At least a portion of the valve member of the second valve assembly is separable from a portion of the second valve assembly to create an opening that provides fluid communication to the chamber.
