Claims

[Scope of Claim for Utility Model Registration] (1) In a fusible safety plug 8 that is attached to the container valve 1 of a pressure vessel using a cap nut 9, the spout 7 of the fusible safety plug is directed vertically upward. A fusible safety plug characterized by being at an angle of 30 degrees or less. (2) A fusible safety plug 8 that is attached to the container valve 1 of a pressure vessel using a cap nut 9, in which the fusible safety plug spout 7 is at an angle of 30 degrees or less with respect to the vertical upward direction. A pin-shaped portion 4 and/or a hole-shaped portion 6 are provided on one end surface of the safety plug 8, and the hole-shaped portion 6' and/or pin-shaped portion 4' that fit with these portions are screwed into the cap nut 9. A container valve soluble safety plug characterized in that it is provided at opposing positions on one end surface of a male threaded portion 3. (3) In the fusible safety plug 8 that is attached to the container valve 1 of the pressure vessel using a cap nut 9, the fusible safety plug spout 7 is at an angle of 30 degrees or less with respect to the vertical upward direction. Hole-shaped portions 6 and 6' are provided at the same positions on one end surface of the safety plug 8 and one end surface of the male threaded portion 3 that faces this surface and is screwed into the cap nut 9, respectively.
A container valve soluble safety plug characterized in that an integrated pin-like member 11 is fitted into these hole-like portions 6, 6' at the same time.
