In a pneumatic container transport system, specialized cylindrical containers move between processing stations through cylindrica conduits propelled by low-pressure, high-velocity air. Annular ridges around the circumference of the containers minimize contact with the inside conduit walls and deter scuffing of labels which carry machine-readable indicia upon which the container transport system relies for directing the containers. In a preferred embodiment, the containers are bottles having a coaxial mouth closed by threaded caps, the caps still preferably including a transparent window to allow visual and spectroscopy analysis of the bottle contents. In an alternate embodiment, the containers are longitudinally symmetrical clamshells for irregularly shaped objects, the clamshells opening through a longitudinal mouth along one side and sealable with tamper-proof labels. |
