Dispensing device for a drink based on a first fluid to which a second fluid can be added selectively, including a support containing a chamber having a first port communicating with a reservoir of said first fluid, a second port communicating with a reservoir of the second fluid, and an outlet port, further including a dispensing assembly mounted movably relative to the support following: a first displacement arranged to selectively open and close the outlet port and/or the first port by a first actuating element for the first displacement; and a second displacement arranged to open and close the second port selectively by a second element to enable the actuation of the second displacement; the second element being arranged to be actuated after the first element and following a type of motion different to the type of motion necessary for the actuation of the first element.

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 container sealing assembly is provided. The container sealing assembly includes a cap configured to attach to a container body and a unitary compliant sealing valve movable between a sealed position and an open position and configured to form a sealing interface with the cap when the unitary compliant sealing valve is in the sealed position. One or more seal-breaking structures may be provided to interact in response to a movement of the unitary compliant sealing valve from the sealed position to the open position, where such interaction is configured to break the sealing interface. A compression spring section of the valve may be provided to assist in moving the unitary compliant sealing valve into the open position.

The present invention provides a rotary-push type cosmetic container. The rotary-push type cosmetic container includes: a lower case; an upper case opening up and closing down with respect to the lower case; an internal container disposed in the lower case and filled with a cosmetic through the back; a rotary plate having an extraction hole at the center and moving up the internal container by rotating about a middle case in the lower case; a piston combined to the lower portion of the rotary plate to generate pressure for extracting the cosmetic in the internal container; and a nozzle plate elastically moved up and down by a spring between the piston and the rotary plate.

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.

A lid connected to a container or body portion of a bottle includes a base defining a conduit, where a rotatable collar coupled to the base rotates about the conduit in a single direction. The lid further includes a spout having a cam defining a path on the outer surface of the spout that engages at least a portion of the collar when the rotatable collar rotates about the conduit. The spout can extend away from the base into an open position and retract proximate to the base into a closed position as the portion of the collar traverses the path defined by the cam when the rotatable collar is rotated about the conduit.
