Title (EN) METHOD OF SUBSTITUTING INERT GAS AND APPARATUS THEREFORE
(FR) PROCEDE DE SUBSTITUTION D'UN GAZ INERTE ET DISPOSITIF UTILISE A CET EFFET
Abstract:
(EN) This invention relates to a method of substituting an inert gas by blowing out an inert gas into a vessel while the opening of the vessel is covered with an inert gas substitution unit (5, 20) having inert gas outlet (7, 30) so as to substitute the inert gas in the vessel, and covering the opening of the vessel with a lid film (15) after substitution. The invention discloses also an inert gas substitution unit (5) having a flat plate on which the inert gas outlet (7) is formed. Disclosed also is an inert gas substitution unit (20) having a chamber (21) whose bottom surface is open and blowing an inert gas into the vessel while covering the opening of the vessel with the chamber (21).
(FR) Procédé de substitution d'un gaz inerte consistant à expulser un gaz inerte dans un récipient pendant que l'ouverture du récipient est couverte par une unité de substitution de gaz inerte (5, 20), présentant un orifice de sortie du gaz inerte (7, 30), de manière à substituer le gaz inerte dans le récipient, et à recouvrir l'ouverture du récipient avec un film servant de couvercle (15) après la substitution. Sont également décrites une unité de substitution de gaz inerte (5) pourvue d'une plaque plate sur laquelle on ménage l'orifice de sortie (7) de gaz inerte, ainsi qu'une unité de substitution de gaz inerte (20), possédant une chambre (21) dont la surface du fond est ouverte, qui souffle un gaz inerte dans le récipient pendant que la chambre (21) couvre l'ouverture du récipient.
