Remote-controlled-lid type pneumatic vessel for powder

摘要

A remote-controlled-lid type pneumatic vessel for powder comprises a vessel (1) having an aperture for storing powder and a lid (2) to be fitted in the aperture. The lid is provided on the outer-peripheral wall thereof with an upper edge (21), a fixed ring (22) and at least one non- slip ring (23) in that order starting at the top of the wall. The vessel is provided on the inside wall of the aperture with a catching groove (11) fitted to the fixed ring (23) of the lid. A predetermined clearance is formed between the end edge (12) of the aperture and the upper edge (21) of the lid while the fixed ring (22) of the lid is fitted to the catching groove (11). This pneumatic vessel can perform pneumatic carrying without using a conventional outer vessel and the lid can be operated through remote control by inserting a simple jig into the clearance. <IMAGE>
