Plastic container
Document Type and Number:
Japanese Patent JP5938853
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a thin-walled plastic container having an excellent barrier property.SOLUTION: The plastic container 1 has a multilayered structure including an intermediate layer made of a gass-barrier resin, and inner and outer layers made of a humidity-resistant resin. A barrel part 5 of the plastic container 1 is formed in a thinner wall than other sections constituting the container, and its outer circumferential surface is covered with a gas barrier property film 8. A resin having the barrier property such as an ethylene-vinyl alcohol copolymer resin (EVOH), a nylon resin, or a cyclic olefin, may be used for the gass-barrier resin of the intermediate layer. An olefin resin such as polypropylene (PP) or polyethylene (PE) is favorably used for the humidity-resistant resin of the inner layer and the outer layer 4.
