1. A carrier vessel for use in a pneumatic tube transport system, comprising:

  • a first shell member having a body and a first engagement surface disposed about the perimeter of said body;

    a second shell member having a body and a second engagement surface interconnectable with portions of said first engagement surface;

    a wear band connected to said first and second shell members, said wear band having a thickness and outer material for contacting the pneumatic tube transport system when the carrier vessel is caused to be transported thereby; and

    a sealing member disposed adjacent said first engagement surface whereby, when said first shell member is interconnected with said second shell member so that said first and second shell members are in a closed position, said sealing member controls passage of fluids into and out of said vessel;

    wherein said wear band is a single one-piece member that includes an integrally formed hinge band that permits said first and second shell members to change from said closed position to an open position while said wear band remains as said single member when said first and second shell members are in said open position.
