An aspect of the invention provides a container closure for a container comprising a body portion having a first end configured for attachment to a container and a second end configured to allow content of the container to exit the container closure, a reservoir positioned within the body portion between the first and second ends thereof and an actuable seal that is moveable between a first configuration in which the reservoir is sealed and a second configuration in which the actuable seal is moved in the direction of the second end of the body portion to create a gap between the actuable seal and second end of the body portion, wherein the actuable seal is moveable between the first configuration and second configuration by a plunger extending from the first end of the body portion to the second end of the body portion and wherein the actuable seal engages a surface of the reservoir when in the first configuration.

An adjustable additive cartridge that provides adjustable metering of additive to a base fluid as the base fluid is flowing through the cartridge. A spout is mounted for limited rotation within a base element of the cartridge. Rotation of the spout results in varying degrees of flow of additive into a base fluid flow path through the cartridge. The cartridge may be used with a portable beverage container, such as a sports bottle or off-the-shelf water bottle. The supply of base fluid in a container used with the cartridge may be kept in an unmixed, pure state, and other cartridges, each having different additives (i.e., flavors) may be used interchangeably with the same base fluid supply. The cartridge allows a consumer/user to experience different additives, such as different flavors or supplement compositions, for a given supply of base liquid in a single container. A check valve on the cartridge prevents backflow of the base fluid. An integrated filter for filtering base fluid flowing into the cartridge may be provided. The additive cartridge may be sealed to provide for extended storage and to provide a user/consumer with evidence of integrity, quality and/or tampering prior to purchase and/or use. Visual and tactile indicators of the amount of additive being added to a base fluid may be provided. A container may retain a spare additive adjustable cartridge on the container.

A kitchenware apparatus and container for producing fermented vegetables, such as sauerkraut, comprising a screw top or Mason jar, a threaded jar lid with moat and an oblong top slot opening, an inverted cup that fits within the moat, a plunger sized to fit within the neck of the jar and having a keyed handle that extends up through the slot in the lid, and a compression spring. The lid moat and inverted cup comprise an airlock or one way valve that allows fermentation gases to escape but prevents outside air from entering. The screw lid, spring and plunger comprise a press that compresses the fermenting vegetables to press juice from the vegetables and to hold the vegetables under the liquid surface to prevent mold or other spoilage and to prevent browning.

A formulation dispensing device can include a cartridge receptacle to accommodate and/or secure a beverage ingredient cartridge and permit contents within the cartridge to flow into a bottle or beverage container. Additionally, a formulation dispensing device can include a drink through valve that can permit mixed contents from a beverage container to flow through the drink through valve and be consumed. For example, the formulation dispensing device can include ingredients that can be added to a range of different drinks, including sports drinks, dietary drinks, and as a critical life supporting drinks in humanitarian situations. The formulation dispensing device can also include a lid configured to pivot between open and closed positions and can seal the dispensing device which allows the beverage container to be inverted during consumption without leakage through the first aperture.

A closure device for use with a container having a container neck comprises a cap member having a first fluid chamber and a housing having a second fluid chamber. The housing is arranged to move relative to the cap member between a first armed position and a second firing position. The housing includes a first plug member adapted to close a bottom aperture in the first fluid chamber in the first armed position. The cap member includes a second plug member adapted to close a bottom aperture in the second fluid chamber in the first armed position. In the second firing position the first plug member is removed from the aperture in the first fluid chamber and the second plug member is removed from the aperture in the second fluid chamber.

A cartridge (1) which is suitable to cooperate with the neck (3) of a container (5) in order to allow a product contained in the cartridge (1) to flow out into said container (5), said cartridge (1) including at least one reservoir (7); moveable sealing means (13) to close the opening (9) of the reservoir (7), and a socket (23) wherein the moveable sealing means (13) comprises at least one ring (19, 21) configured to cooperate with the neck (3) of the container (5) in order to allow the moveable sealing means (13) to slide along the lower wall (11) of the reservoir (7) by a pressure exerted on said ring (19, 21) by the neck (3) of the container (5) causing the opening of the one or more flaps (17) and further wherein at least one ring (19, 21) of the moveable sealing means (13) comprises holding lugs (25) configured to cooperate with an internal relief (27) of the socket (23) in order to maintain the moveable sealing means (13) in position inside the socket (23), closing the opening (9) of the reservoir (7).

A reusable vessel comprises a first compartment to store therein a substance and a second compartment separated from the first compartment by a boundary element comprising a wall or membrane having one or more apertures therein. A valve is movable between a closed position, in which the valve seals the one or more apertures, and an open position allowing the substance to be released from the first compartment into the second compartment, or a substance in the second compartment to mix with the substance in the first compartment. A triggering mechanism is coupled to the valve to move the valve between the open and closed positions. The triggering mechanism comprises one or more external elements coupled to one or more internal cam elements to control the valve, which, when triggered causes the one or more external elements to exhibit a visible change to indicate the open and closed positions of the valve.

A closure assembly for a container comprising a pressurised tank and a plug member, the pressurised tank has an interior volume and a cylindrical wall including an annular boss member at its open end. The plug member has an annular channel arranged at a first side of the plug member adapted to sealingly engage with the boss member. The channel has at least one orifice extending from the floor or outer side wall of the channel to a nozzle at the second side of the plug member. The orifice is sealed from the interior volume of the tank when the channel is sealingly engaged with the boss member in a first position, but is in fluid communication with the interior volume of the tank when at least part of the channel is no longer engaged with the boss member in a second position.

A reconfigurable container-closure system is comprised of first and second containers and first and second closures. The container-closure system can assume either of two configurations. First configuration means that the first closure (12) is secured to the first container (10), and the second closure (112) is secured to the second container (110). Also, an orifice reducer (113), cartridge (114) and sleeve (115) are all attached to the second closure (112), and two products are separated. Second configuration means that the second closure (112) is secured to the first container (10), and the first closure (12) is secured to the second container (110). Also, the orifice reducer (113), cartridge (114) and sleeve (115) are all attached to the first container (10), and two products are allowed to mix and be dispensed. The transfer is accomplished by a user who simply screws the second closure onto the first container (10).
