PROBLEM TO BE SOLVED: To improve the deoxygenation capability, and eliminate problems in safety and higienical property by a method wherein a container main body is formed of a multi-layer material having a gas barrier layer of which the oxygen permeability is specified, and one end of a spout is bonded to the innermost surface of the container. ;SOLUTION: A container main body 1 is formed of a multi-layer material 10 wherein an oxygen absorbent resin layer 13 is made an intermediate layer, and a gas barrier layer 11, is provided for the external layer, and an oxygen permeable resin layer 14 is provided for the internal layer, and on this container main body 1, a spout 24 which can be sealed, is provided. The gas barrier layer 11 has a gas barrier property of which the oxygen permeability coefficient at 20°C, 100%RH, is 1.0cc-mm/m².day.atm or less. The oxygen absorbent resin layer 13 comprises of a resin composition for which an oxygen remover composition is dispersed in a thermoplastic resin. The oxygen permeable resin layer 14 forms the innermost layer of the container, and prevents the oxygen remover component of the oxygen absorbent layer 13 from melting into a liquid or semi-liquid content. The spout 24 is provided by bonding to the innermost surface of the multi-layer film 10 so that oxygen may not leak into the container after the filling of the content until an unsealing.;COPYRIGHT: (C)1997,JPO
