A collapsible container for medical use which has an improved low temperature characteristics and can withstand high temperatures of high-pressure steam sterilization, includes a container main body made by irradiating a hollow molding having a desired shape formed of an ethylene-vinyl acetate copolymer with an electron beam to cross-link the copolymer, thus providing a main body. The main body is completely sealed at its periphery except for a predetermined portion providing a non-sealed portion. The end of a functional accessory for achieving the function of the container for medical use is inserted in the non-sealed part of the main body. The accessory is sealed, at the inserted end, to the main body through an interlayer of a non-cross-linked ethylene-vinyl acetate copolymer.

A flexible and collapsible container for medical use which has an improved low temperature characteristic and can withstand high temperatures of high-pressure steam sterilization, comprising: a container main body made by irradiating a hollow molding having a desired container shape, formed of an ethylene-vinyl acetate copolymer containing 10 to 35% by weight of vinyl acetate, with an electron beam to cross-link the copolymer whereby said cross-linked copolymer has a gel content of 50 to 85% by weight, said container main body being completely sealed at its periphery except for a predetermined portion providing a non-sealed portion; a functional accessory for achieving the function of the container, having an end portion inserted in the non-sealed portion of the container main body, said functional accessory being made of a polymeric material, and having sufficient heat resistance to withstand high-pressure steam sterilization; and an interlayer for sealing said container main body at the non-sealed portion thereof to the inserted end portion of said functional accessory, said interlayer being made of a non-cross-linked ethylene-vinyl acetate copolymer containing 15 to 40% by weight of vinyl acetate.
