Definitions

• the invention relates to a container which is filled with liquid and sealed pressure-tight and can be removed from the liquid.
• containers are Fasser, Kleinanker (Partylase) or cans in which CO 2 -containing liquids, especially drinks, are filled under pressure. It's all about party-gatherers for beer.
• Party192 for beer which have an integrated outlet tap in the bottom area of the barrel over which the removal of the beer is done solely by the internal pressure and gravity.
• the party keg is vented above the liquid level therein to induce pressure equalization. This can be done by piercing a can opener.
• Party192er for beer with an integrated tap and a handbetuftippon ventilation valve in the barrel top which is part of a bunghole closure (see WO 99/23 008 Al).
• a CO 2 dispenser for Partyanker in the form of a separate handset is known, with the party keg is pierced above the Flusstechnikspegels therein to spend CO 2 in the headspace of the barrel.
• the dispenser has a C0 2 high pressure cartridge and a pressure control valve. It is intended for multiple use and can be implemented from party keg to party keg. Although C0 2 consumption may be lower than that of CO 2 dispensers, such CO 2 dispensers in the consumer community ultimately face similar concerns.
• a pressure bag into the head space of a beer keg which expands when the pressure in the head space drops, thereby filling the hollow space that forms and secondly pressing pressure on the liquid level the barrel that exceeds the partial pressure of CO 2 released in the beer.
• the pressure bag consists of multilayered, oxygen-impermeable plastic film. He has several chambers containing gas-evolving chemicals, such as baking soda and citric acid. Depending on the pressure drop, the chambers are successively activated in the headroom of the party keg and inflated by the gas evolving during the reaction of the chemicals.
• a disadvantage of the known pressure bag is the unsteady Druckaus ⁇ exercise on the beer.
