Beverage container made of a thermoplastic resin, in particular pet

Abstract

The invention relates to a drinks container ( 2 ), produced from a thermoplastic material, in particular PET, comprising a tapping valve unit ( 9 ) and a CO 2 pressurized gas dispenser arranged in the interior of the container for discharging the liquid of the drink and having assigned to it a pressure regulating unit ( 8 ), which releases the pressurized gas from the CO 2 pressurized gas dispenser into the liquid of the drink as soon as the pressure in the drinks container ( 2 ) drops when liquid is removed. The intention is to provide a drinks container that allows a simpler construction and improved handling. For this purpose, the CO 2 pressurized gas dispenser is a container ( 3 ) that likewise consists of thermoplastic PET material and is filled from the outset with CO 2 pressurized gas.
