Closure assembly

A closure assembly comprising:

• a transfer tubing having a multiple layered structure defining a fluid passageway, the tubing having an end surface;
• and
• a membrane material disposed across the fluid passageway to provide a fluid tight seal.

A closure assembly comprising:

• a transfer tubing having a multiple layered structure having a first layer of an ethylene vinyl alcohol copolymer and a second layer of a polyolefin, the tubing defining a fluid passageway, the tubing having an end surface;
• and
• a membrane material having a first layer of an ethylene vinyl alcohol copolymer and a second layer of a modified ethylene vinyl acetate copolymer, the membrane material disposed across the fluid passageway to provide a fluid tight seal.

A closure assembly comprising:

• a transfer tubing having a first layer of an ethylene vinyl alcohol copolymer, a second layer of a polyolefin and a third layer selected from the group consisting of polyamides and polyesters, the tubing defining a fluid passageway, the tubing having an end surface;
• and
• a membrane material having a first layer of an ethylene vinyl alcohol copolymer, a second layer of a modified ethylene vinyl acetate copolymer and a third layer selected from the group of polyamides and polyesters, the membrane material being disposed across the fluid passageway to provide a fluid tight seal.
