It is disclosed a container (1) aimed at containing perishable goods, which can be sealed after storing the goods inside it, comprising at least one valve (5, 6) to let the gas flow in one and/or in the other direction, wherein said at least one valve (5, 6) acts in a first process (5) preventing gas from coming out from inside the container and a second process (6) preventing gas from entering the container (1) from outside. Said container (1) also comprises a vacuum gauge, a dosed air intake system. It is also disclosed a process for the preservation of perishable goods, comprising the following steps: a) introducing perishable goods into a container (1) comprising at least one valve (5, 6) to let the gas flow in one and/or in the other direction, in a way (5) adapted to prevent gas from coming out from inside the container and in a second way (6) to prevent gas from entering the container from the outside b) sealing the container (1) c) removing a substantial part of the air left inside the sealed container (1) d) introducing an amount of oxidising gas through one of the gas valves (5) e) the oxidising gas is left inside the container for 1 to 5 minutes, preferably 1 to 3 minutes f) creating vacuum inside the container by sucking out the gas through one of the gas valves (6). According to the present invention, the process also comprises the following steps: g) checking that the pressure inside the container is below a given threshold h) if the threshold is exceeded, extracting the gas until a lower threshold is reached i) introducing air slowly and gradually. Preferably, said oxidising gas is ozone. According to a third aspect, it is also disclosed an ozone settler in a closed circuit.Linvention concerne un récipient (1) destiné à contenir des denrées périssables, qui peut être fermé hermétiquement après la disposition des denrées à lintérieur de celui-ci, comprenant au moins une valve (5, 6) servant à permettre un écoulement de gaz dans une et/ou dans lautre di
