Method of making release points for gas bubbles in the inside surface of containers for receiving gaseous or gas-saturated liquids, and container with release points of this type

摘要

Release points (6) in the form of recesses with a smooth surface are formed in a contactless manner by means of a laser in the inside surface of the bottom (4) or the wall of a drinking vessel (1). After a gaseous liquid (7) is poured in, gas bubbles (8) rising at the release points (6) are produced which, on account of the intended arrangement of the release points (6), produce a characteristic and attractive appearance.
