DEVICE FOR THE CONTROLLED TRANSFER OF VOLATILE GASES OR GASEOUS MOLECULES INTO A CONTAINER INTENDED TO CONTAIN A LIQUID OR SEMI-LIQUID FOOD PRODUCT

摘要

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.

1. A controlled gas transfer device for the controlled transfer of volatile gases or gaseous molecules into a container intended to contain a liquid or semi-liquid food product, the device comprising:
a rigid capsule forming a chamber whereof one longitudinal end (6a) is open, and forming a longitudinal duct for the flow of a liquid or semi-liquid food product; an active product contained in the said chamber, capable of absorbing a volatile gas and/or volatile gaseous molecules present in the said food product or of diffusing a volatile gas and/or volatile gaseous molecules in this food product; a closure cap for closing the said open longitudinal end of the chamber, comprising a penetrable septum, the said cap being able, when it is placed on the said capsule and its septum is not perforated, to close off the chamber in such a manner that it is sealed against gases and water, and allowing, when it is perforated, for a transfer of volatile gases and/or volatile gaseous molecules between the exterior and the interior of the chamber; and a gas permeable membrane permeable to the volatile gases and/or volatile gaseous molecules to be absorbed or diffused, placed in the chamber in a manner so as to separate the active product contained in the chamber from the exterior.
