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.
A hydraulically transported capsule comprising a cylindrical shell adapted to contain goods to be transported, and a cover member made from a flexible material and adapted to be fitted over one end portion of said shell, said shell being formed at its leading end portion with a fitting portion for said cover member, said cover member being fitted over said fitting portion of the shell to close said one end portion of the shell, and said cover member having an outer peripheral surface serving as a sliding surface of the capsule, wherein the sliding surface of said cover member has sliding means comprising a plurality of supporters arranged at least in a row circumferentially of the cover member, said supporters comprising elongated resilient members embedded in said sliding surface and extending radially outwardly of said sliding surface.
