A beverage server for pouring a beverage includes tubular through-screw portion 4, gas supply tube 2, gas supply device 3, gate valve 43, tubular pouring portion 5, and check valve 51. The gate valve is configured to be opened and closed with the pouring portion. The pouring portion has beverage supply hole 53 formed at a lower end portion thereof. Food additive gas supplied from the gas supply device is supplied from the gas supply tube to the through-screw portion and supplied to internal space S through a space between an outer wall of the pouring portion and an inner wall of the through-screw portion. The food additive gas exerts a pressing force that causes the beverage to flow to the inside of the pouring portion through the beverage supply hole, open the check valve, and be poured through an orifice of the pouring portion.

Embodiments of the present invention include a liquid dispensing container and lid with a straw releasably attachable below the lid, the container with a first configuration allowing a user to sip liquid from the container at a first location when the straw is attached to the lid, and a second configuration that allows a user to pour liquid from the container, at the same first location, when the straw is not attached to the lid.

A self-adaptive air bag blocking device is disclosed. The device includes an air bag, a first gas conveying pipe and a second gas conveying pipe, wherein an air chamber is formed in the air bag, a ring-shaped abutting surface is formed on the peripheral side of the air bag, so that the abutting surface abuts against a mouth of a container. The first gas conveying pipe is communicated with the air chamber and the outer part of the air bag, so that air enters the air chamber to enable the air bag to expand. The abutting surface is elastically deformed and tightly abuts against the inner wall of the container to form air-tight abutment, and the second gas conveying pipe is arranged on the air bag, so that air enters the container through the second gas conveying pipe, and thus the working liquid is discharged.

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 fluid transfer hub has a first vessel closure, a second vessel closure, a gasket arranged between the first vessel closure and the second vessel closure, and a clamp at least partially surrounding the first vessel closure, the second vessel closure, and the gasket. The first vessel closure has a first body, one or more apertures extending axially through the first body, one or more first inserts extending axially through the one or more apertures, and a cast seal disposed within the first body and surrounding each first insert. The second vessel closure has a second body, one or more apertures extending axially through the second body, one or more second inserts extending axially through the one or more apertures, and a cast seal disposed within the second body and surrounding each second insert.

A closure assembly for a dispenser container comprises a base defining a longitudinal recess and a body configured to be moveably coupled to the base. The base comprises a first seal positioned at a first end of the recess and a second seal positioned at an opposing second end of the recess. The body comprises a first body end and an opposing second body end. A shaft extends from the first body end to the second body end. The body is configured to move between an open position where the body is fluidly connected with the recess, and a closed position where the body engages the first seal and the second seal. The first seal and the second seal are configured to exert a force toward each other in a direction along a longitudinal axis of the body to tension the body.

A drinking device for the retronasal perception of an aroma substance comprises a storage container for drinking liquid, at least one aroma container, through which air can flow, and a transporting channel for drinking liquid. The transporting channel runs from the storage container to a mouth end of the drinking device. The drinking device also comprises an air channel for transporting aromatized air. The air channel running runs from at least one of the at least one aroma containers to the transporting channel for drinking liquid or to the mouth end.
