Abstract: An apparatus for aerating for domestic use beverages, such as flavored water. The apparatus comprises a stand (2) with space assigned for a glass bottle (4) and with space assigned for a gas tube (4) containing carbon dioxide, and a sealing member (7) for sealing the mouth (8) of a glass bottle (4) during the aerating process.According to the invention, at the place for the glass bottle (4) a bursting protection (15) is provided, which is movable upward and downward in relation to a glass bottle (4) positioned and to the stand (2), and which in its upper position permits free insertion and removal of a glass bottle (4), and in its lower position encloses entirely a glass bottle (4) thus positioned. The sealing member (7) is located in the upper portion of the bursting protection (15) and capable to seal against the mouth (8) of a glass bottle (4) only when the bursting protection (15) is in its lower position. Hereby a safe and easily handled apparatus is obtained.
