Abstract: A conveying capsule for a pneumatic tube conveyor system is formed with a capsule body the open end face of which is closed with a lid. The lid is hinged on the capsule body about a transverse pin, and it has a lid closure on the side of its peripheral wall opposite from the hinge pin. The closure is formed with a closure hook that engages into a latching cutout formed in the capsule body. An actuating lever for the closure hook is articulated in a wall recess on the outside of the peripheral wall and the inward-pointing closure hook engages into the latching cutout which is open towards the outside. An annular seal is disposed between the lid and the capsule body. The seal is inserted into an annular groove formed in the end face of the peripheral wall of the lid or of the capsule body.

Abstract: The insert for a pneumatic tube conveyor capsule holds test tubes in the capsule. The insert has a frame coaxial with the pneumatic tube conveyor capsule. The frame forms two or more trays and an intermediate tray farmed with throughholes into which the test tubes are inserted and secured axially between the two trays. A supporting column connects the two trays and the intermediate tray and has an axial plug-in connection for one of the two trays with an axial clamping device. The axial clamping device includes two spring-loaded tongues opposite one another relative to the axis of the frame, extending in the direction of the supporting column between the intermediate tray and the tray that is removably placed on the plug-in connection. The tongues are attached to or formed onto one of these structural parts and they forming a snap closure with locking recesses on the respective other structural part.
