A capsule holder for holding a gas capsule for an apparatus for output of an output medium includes a gas capsule holder element configured as a deep-drawn part having an opening for holding the gas capsule. A cover configured essentially in the manner of a sleeve surrounds the gas capsule holder element from the outside, at least in certain sections. The capsule holder includes a threaded ring configured as a separate element, having an inside thread and/or an outside thread, wherein the threaded ring is firmly connected with the gas capsule holder element and arranged in the region of the opening, so as to make introduction of the gas capsule into the gas capsule holder element possible through the threaded ring.

A novel pressure control system provided for maintaining a constant predetermined excess pressure in a fluid dispensing container comprises a high-pressure plastic vessel having an inner chamber and an upper open end, and a pressure control device with a valve, which pressure control device is mounted on the upper open end of the high-pressure vessel, whereas a passageway is provided from the inner chamber to the outside, which is controlled by the valve, wherein the vessel is substantially cylindrical.

The upper part of the vessel has a spherical dome with a cylindrical insert provided for receiving the pressure control device and the lower end of the vessel has an open end, which is closed by a ring-shaped closure.

A novel foam dispenser is described, which comprises a dispensing container, a valve with a downstream foaming chamber and a pressure control device for maintaining a constant pressure in the container, such that uniform and compact foam will be created.

A pressure control system provided for maintaining a constant predetermined excess pressure in a fluid dispensing container comprises a high-pressure plastic vessel having an inner chamber, and a pressure control device having a valve and mounted on the open end of the high-pressure vessel, whereas a passageway is provided from the inner chamber to the outside, which is controlled by the valve. A piston with a protruding stem is provided in a guide member, whereas between the guide member and the piston a chamber with a gas with a reference pressure smaller than the high pressure is enclosed, and the high pressure vessel is closed by a closure with a central bore of smaller diameter than the diameter of the stem, and the piston end remote from the protruding stem is pressurized by the fluid in the fluid dispensing container.

A novel pressure control system is provided for maintaining a constant predetermined excess pressure in a fluid dispensing container, comprising a high-pressure plastic vessel having an inner chamber, a closed end and an open end, and a pressure control device with a valve, which pressure control device is mounted on the open end of the high-pressure vessel, whereas a passageway is provided from the inner chamber to the outside, which is controlled by the valve, wherein the high-pressure vessel is essentially spherical.

A valve assembly for a pressurized container includes a valve stem and a mechanical seal. The valve stem has an open top portion, a closed bottom portion, at least one primary radial opening, at least one secondary radial opening and a valve stem passageway between the open top portion and both the at least one primary radial opening and the at least one secondary radial opening. The mechanical seal comprises a longitudinal passageway that seals the at least one primary radial opening and the at least one secondary radial opening, respectively, when the valve stem is in a closed position. Longitudinal translation of the valve stem exposes the at least one primary radial opening or both the at least one primary radial opening and the at least one secondary radial opening to the pressurized container when the valve stem is in an open position.

A discharge device is provided with a pressurized product filling and sealing the concentrate and the pressurizing agent P inside the container, and a discharge member discharging the concentrate by breaking through the pressurized product. The discharge member is provided with a valve which becomes a discharge passage of the concentrate, and a cap which covers the valve and is detachably mounted to the pressurized product. The discharge device is provided with a suppressing means (a maintaining mechanism, a movable lid, pressing to the bottom of the recessed part of the projecting part, a part releasing mechanism, a ratchet mechanism, a thin part and a plurality of coupling parts) for suppressing the leakage of the concentrate caused by removing the valve.

A pressurized beverage dispenser having a beverage container and a cap. The cap includes a cap body, a compressed-gas cartridge, an external straw, a discharge chamber, a metering valve, a diaphragm, and an actuator. The discharge chamber within the cap body is in fluid communication with an internal passageway of the external straw. The metering valve allows a flow of beverage from the beverage container to the discharge chamber when the metering valve is open and substantially precludes the flow of beverage when the metering valve is closed. The diaphragm opens the metering valve when the diaphragm is activated and closes the metering valve when the diaphragm is deactivated. The diaphragm also activates when a user sucks on the outlet end of the external straw to create suction within the discharge chamber. The actuator on the cap body activates the diaphragm when the user manually engages the actuator.
