Abstract: A capsule having a cylindrical shell for containing goods to be transported, and a cover member adaped to be fitted over one end of the shell. The cover member is made from a flexible material and is provided on the leading end of the shell. The provision of the cover member of a flexible material avoids damage to or deformation of the capsule which would otherwise be caused by collision against the preceding or the next following capsule, and reduces the resistance offered to the movement of the capsule by the tubular passageway through which the capsule is moved.

Abstract: A capsule hydraulic-transportation system for use in continuously transporting capsules through a pipe line, in which system a discharge duct is connected in parallel at a forwarding station to a plurality of feeding ducts for feeding capsules, and the plurality of feeding ducts are by turns in timed sequence operated to continuously charge capsules into and transport same through the discharge duct to the pipe line.
