Abstract: A disposable container for beverages (6) complete with a hermetic closing device (23), and realised in a plastic and/or thermoplastic material by means of a mold-blowing technique; the main characteristic is that it permits the drinking of a single portion of the beverage, whether water, wine or some other gaseous or natural beverage, which maintains the integral flavour and amount of gas that may be contained in said container, in the same condition as that poured from a freshly bottle.
