DISCHARGE PORT MEMBER FOR CONTAINER, PART THEREFOR AND CONTAINER

摘要

PURPOSE: To obtain hermetic sealability at a low cost and to facilitate opening and closing operation. ;CONSTITUTION: In the discharge port member 10 equipped with a fluid inflow port 19 and a fluid outflow port 17 attached to a fluid housing container 11, at least a part of the wall 13 constituting the passage from the inflow port to the outflow port is separated from the inner surface of the opposed wall and closely brought into contact with the inner surface of the wall 20 as shown by the broken line of a drawing (c) to selectively take a shape opening the passage and a shape closing the passage. As mentioned above, the walls 13, 20 of the passage are deformable and, on the way deforming from one shape to the other shape, the reaction force of at least a part of the walls to external force is reversed.;COPYRIGHT: (C)1997,JPO
