ABSTRACT:
According to this process, the container (2) is filled, and after filling a capsule (6) carrying a valve is fixed in a sealed manner to the neck (21) of the bottle (2), said valve consisting of a membrane (5) of elastomeric material of thickness such that that valve can become sealed again by elastic recall after having undergone aspiration in order to create a reduced pressure and/or the introduction of unreactive gas, the capsule (6) and the valve (5) remaining on the container (2) and maintaining the seal of the container (2) during storage. A top cap (4) may receive the valve (5) and contribute to sealing. The invention also relates to a packaging unit for the implementation of this process.
