Abstract: A carrier vessel for a pneumatic tube transport system provides substantially leak-free containment of fluids transported therein. The vessel includes first and second shell members having opposing engagement surfaces extending substantially about a perimeter thereof. A sealing member disposed adjacent one of the engagement surfaces is compressed between the engagement surfaces when the vessel is closed to provide substantially fluid-tight seal between the first and second shell members. The vessel includes removable wear bands connected to the shell members, a hinge interconnector assembly for connecting the shell members together at one of their longitudinal sides and latch assemblies for releasably connecting them together at an opposite longitudinal side.
