ABSTRACT:
The container according to the invention is intended for pneumatic transportation of loads through a pipeline. The container comprises a body which is provided at the ends with a front cup and a rear cup, said front and rear caps closing the lower and upper halves, respectively, of the gap between the container body and the pipeline. Arranged on the sides of the body are longitudinal cups which rest on guides secured to the internal side wall of the pipeline and serve as sliding supports for the container. Each longitudinal cup is connected with the body by a device mounted on said body and intended for resilient pressing of said cup against the guide and by a partition which seals off the gap between the body and said longitudinal cup and permits the body to move vertically relative to the longitudinal cup.
