Discharge port of the discharge equipment part of the tube type container that opens and closes naturally

摘要

PROBLEM TO BE SOLVED: To provide a tube-type container capable of preventing unnecessary contact between a content and a foreign substance. SOLUTION: The cylindrical discharge part of the container is not opened, but is closed with a circular lid, the center of the lid is cut and separated, and two semicircular lids are used to open the lid and the discharge part only by the pressure from the inside. A part of the tip is cut and separated. At the time of discharge, the contents are discharged by compression with a slight grip strength, and by reducing the grip strength after discharging an appropriate amount, the container is restored to its original shape due to the shape memory of the material, and at the same time, the contents are sucked by the decrease in internal pressure. The lid of the discharge part is also closed. [Selection diagram] Fig. 2
