Zusammenfassung:PROBLEM TO BE SOLVED: To facilitate the storage and the carrying while preventing a quality deterioration from generating by a method wherein a specified amount of a liquid or a semi-liquid substance is filled in a container or a bag comprising a multi-layer material being equipped with a gas barrier layer comprising a material having a specified oxygen permeability coefficient, an oxygen absorbent layer, and an oxygen permeable resin layer. SOLUTION: When a liquid or a semi-liquid substance such as beverage, seasoning or medicine, is filled, in a container or a bag comprising of a multi- layer material being equipped with a gas barrier layer comprising of a material of which the oxygen permeability coefficient at 20 deg.C/100%RH is 1.0cc-mm/ m .day.atm or less, an oxygen absorbent layer for which a granular free oxygen absorber composition is dispersed in a thermoplastic resin, and an oxygen permeable resin layer, a liquid or a semi-liquid substance is filled in such a manner that a space volume in the container may be 10% or less of the filling volume. As the thermoplastic resin to form the oxygen absorbent layer, polyethylene, polypropylene, polyolefine such as ethylene-α olefine various kinds of copolymers, and their denatured substances, are used solely or by being mixed.
