The invention relates to a drink receptacle (1), especially in the form of a drinking bag, having a wall (2) composed of a flexible composite material (3), the composite material (3) being water-impervious and gas-impervious and being at least essentially impervious to chemical and biological toxins, in particular warfare agents, or at least retarding their passage, and comprising an outer backing layer (4) and a film-like inner layer (5), wherein the backing layer (4) is textile-like and the inner layer (5) is laminated onto the backing layer (4), in particular at least essentially coextensively. The drink receptacle (1) of the invention combines good NBC protective or resistance properties with high mechanical stability, in particular puncture resistance, and also with a greater ease of manufacture.
