Abstract

According to the invention, this device includes a rigid capsule (2) forming a chamber (6) whereof one longitudinal end (6a) is open, and forming a longitudinal duct (7) for the flow of a liquid or semi-liquid food product (300); an active product (3) contained in the chamber (6), capable of absorbing a gas and/or volatile gaseous molecules present in the food product (300), or of diffusing a volatile gas and/or gaseous molecules into the food product (300); a cap (4) for closing the open longitudinal end (6a) of the chamber (6, having a penetrable septum (4c), the cap (4) being able, when it is placed on the capsule (2) and its septum (4c) is not perforated, to close the chamber (6) so that it is sealed against gases and water, and allowing, when it is perforated, a transfer of volatile gases and/or gaseous molecules between the outside and the inside of the chamber (6), and a membrane (5) permeable to the volatile gases and/or gaseous molecules to be absorbed or diffused, placed in the chamber (6) so as to separate the active product (3) contained in the chamber (6) from the outside. The invention also relates to a closure for a container as described above, comprising the device (1), a method for manufacturing a container comprising such a closure, and a machine for implementing this method.
