ABSTRACT:
A carrier for transporting articles in a pneumatic tube system including, in one preferred embodiment, an elongated cylindrical body completely closed at one end and having an opening in the side wall thereof extending from the other end of the carrier a substantial distance along the length thereof, but substantially less than the entire carrier length, and having a width measured circumferentially approximately one-half of the carrier circumference. A semi-cylindrical cover is hinged to the carrier body along one longitudinal edge thereof to selectively close the opening in the side wall. Also included are mating semi-circular discs integral with the outer ends of the semi-cylindrical cover and cylindrical body section which cooperate to seal the end of the carrier adjacent the side wall opening when the semi-cylindrical cover is in its closed position sealing the side wall opening. Other embodiments are also disclosed.
