Abstract
Provided herein is a pneumatic carrier having a leak resistant cargo area where first and second mating shells form the carrier. To provide a leak resistant cargo area, the one embodiment of the carrier employs a cantilevered sealing element on a first sealing periphery of the first shell. A free end of the cantilevered sealing element is configured to engage a sloped surface on a second shell. As the shells close, the sealing element slides down the sloped surface to form a seal between the shells. The use of the cantilevered sealing element in conjunction with the sloped surface reduces the compressive force required to form a seal between the shells.
