<p>PROBLEM TO BE SOLVED: To suppress the decrease of preservability of fragrance and flavour resulting from elution of an oxygen-absorbent or oxidized products thereof, and retain the preservability of the contents and fragrance and flavour for a long time. SOLUTION: Thermoplastic resin layers in which an oxygen-absorbent is not yet mixed, are laminated at both sides of a thermoplastic resin layer containing an oxygen-absorbent to constitute this container. In this case, the resin matrix of the thermoplastic resin layers containing an oxygen-absorbent is constituted of a blended substance of a plurality of substantially incompatible thermoplastic resins or elastomers, the incompatible thermoplastic resins or elastomers are unevenly distributed in the resin matrix.</p> |
