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.

A closure for a beverage container that includes a base portion configured to couple to the beverage container, a top portion rotatably engaged with the base portion, the top portion comprising a drinking opening, and a central portion removably coupled to the base portion and to the top portion, wherein the central portion comprises a plug. The central portion moves in a first direction along a central axis when the top portion is rotated about the central axis from a first configuration to a second configuration. The central portion moves in a second direction along the central axis when the top portion is rotated about the central axis from the second configuration to the first configuration. The central portion seals the drinking opening when the top portion is in the first configuration.

The present disclosure relates to a pilferproof cap assembly(100) for a container(10). The assembly(100) is configured to facilitate refilling and decanting of fluid in the container(10). The assembly(100) comprises a neck housing(12) and an adaptor(40). The neck housing(14) is configured to be fitted on an opening of the container(10). The neck housing(12) is provided with a linearly displaceable diaphragm(24) to define a fluid-orifice(50) for fluid flow, and an air-orifice(30) to facilitate air flow. The adaptor(40) is configured to be mounted on an operative top of the neck housing(12) and is further configured to actuate the fluid-orifice(50) and the air-orifice(30) in an operative configuration of the assembly(100). The assembly thus facilitates the refilling and decanting of fluid therefrom in a pilferproof manner.

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.

The present disclosure belongs to the field of packaging, and provides a rotary sealed packaging container which comprises an outer lid, a hollow inner core and a container body, wherein the inner core is mounted on an opening part of the container body so that the inner core can relatively move in axial direction of the container body and cannot relatively rotate in the circumferential direction, and the outer lid is mounted on the opening part so that the outer lid cannot relatively move in the axial direction and can relatively move in the circumferential direction; the outer lid is internally provided with a hollow thread part, an inner thread is arranged on the inner wall of the thread part, an outer thread is arranged on the outer wall of the inner core, the inner thread of the thread part matches with the outer thread of the inner core.

The spill proof bottle (10) disclosed comprises a container (22) suitable for holding a liquid and a lid (12) adapted to fasten to the container (22). The lid (12) has a base (16), a spinner (14), a twister (32) and a seal (20). The base (16) is configured with a channel (30) and a post (18). The post (18) has at least one outlet (28) for directing liquid out of the container (22). The spinner (14) has slots (62) and the twister (32) has complimentary tabs (60) adapted to convert rotational motion of the spinner(14) to vertical motion of the twister (32). The spinner (14) moves vertically from an open state to a closed state and then to a removable state. The seal (20) is fastened to the twister (32) and is adapted to cap the channel (30) preventing the flow of liquid out of the container (22) when in the closed state.

A lid assembly that includes a lid body member, a stopper, and a flow control. The lid body member includes a pouring aperture configured to allow a fluid to flow therethrough. The stopper allows the fluid to flow through the pouring aperture at first and second flow rates when the stopper is positioned in first and second open positions, respectively. The second flow rate is faster than the first flow rate. The flow control is operable to position the stopper in the first and second open positions.

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.
