Pneumatically conveyed container with air tight sealing and guide means

A container for pneumatic transportation of loads through a pipeline wherein the internal surface of the pipeline has guides located opposite each other throughout the pipeline length, said container comprising:

• a body;
• a front cup means mounted on the front end face of said body in the direction of movement of said body for sealing off the lower half only of the gap between said body and the pipeline;
• a rear cup means mounted on the rear end face or said body for sealing off the upper half only of the gap between said body and pipeline;
• longitudinal cup means located on the sides of said body and extending between said front and rear cup means, said longitudinal cup means resting on said guides located in said pipeline and serving as sliding supports for the container during movement;
• said longitudinal cup means installed at a certain distance from the sides of said body;
• means for resilient pressing of said longitudinal cup means against said guides and for connecting said longitudinal cup means with said body;
• a plurality of partitions located along the sides of said body, each partition secured to said body at one side and secured to the corresponding longitudinal cup means at the other side;
• said partitions permitting vertical motion of said body relative to said longitudinal cup means and for sealing the gap between said body and said longitudinal cup means.
