FILLER GAS PRESSURE VESSEL DISPLAY THE VALIDITY PERIOD

摘要

PURPOSE: An apparatus for displaying the expiration date of high pressure container for charging gas is provided to specifically distinguish the expiration date of high pressure container, thereby scientifically reading the expiration date of high pressure container. CONSTITUTION: An apparatus for displaying the expiration date of high pressure container for charging gas includes an expiration date displaying plate (100) and a cover fixing plate (110). The expiration date displaying plate is formed with the curvature corresponding to the inner circumferential surface of high pressure container, and is formed in a rectangular plate shape and formed of a material that has the same melting point as the material of high pressure container or the higher melting point than the material of high pressure container. Therefore, the expiration date of the high pressure container is displayed on the front of the expiration date displaying plate. The cover fixing plate includes a displaying plate seating portion (114) on which the expiration date displaying plate is seated so that the expiration date displaying plate is seated. The cover fixing plate is fixed to the inner circumferential surface of the high pressure container through the spot welding of an edge of the cover fixing plate, the front surface of the expiration date displaying plate is closely spaced and fixed to the inner circumferential surface of the high pressure container.
