Definitions

• This invention relates to a tapping device and to a drink dispensing device comprising said tapping device.
• tapping device is used to denote means for dispensing a drink from a container.
• dispenser device is used to denote a device comprising at least the tapping device and the container.
• Devices of this kind are designed to draw drinks from respective containers and to allow the drinks to be dispensed to individual users. They are -normally used in bars, restaurants, cafeterias and other establishments authorised to serve drinks to the public, and also in the home.
• the pressure of the gas increases the pressure inside the container in such a way as to force the drink out through a channelling system to ; a line that connects the container to the tap.
• prior art teaches the use of tapping heads connected by fittings of various kinds (for example of the sliding, triangular of bayonet type) to the top face of the container where there is a shutter.
• the tapping head comprises an element that can be coupled to the container and a piston that moves relative to said element and relative to the container.
• a spring keeps it pressed against a fixed part of the container, thereby preventing the drink from flowing out.
• the piston is placed in direct contact with the shutter and overcomes the elastic force of the spring, thus allowing the drink to flow out of the container.
• the piston is hollow to enable the drink to flow out through it.
• the end of the piston opposite the end that interacts with the shutter has connected to it a plastic tube that conveys the drink to the dispensing point. Tapping devices of the kind described above are not free of disadvantages.
• the inside walls of the piston come into direct contact with the drink.
• the piston must be periodically sanitized.
• sanitization of the piston is performed directly at the place where the device is used, which involves the use of specialised personnel at the place of use. This in turn involves additional costs.
• the container on the other hand, is normally sent to the manufacturer to be sanitized, filled and then sent back to the place of use. This results in further costs.
• the present invention therefore has for an aim to overcome the above mentioned disadvantages by providing a tapping device and a drink dispensing device comprising said tapping device allowing the maximum level of hygiene to be achieved.
