Publication No. 54518 discloses that packing is inserted between the tip of the donut-shaped flange of the cap cover and the outer peripheral surface of the flange of the cap to seal the space between the cap cover and the upper part of the cap. This prevents rainwater etc. from entering from the top and prevents corrosion of the threaded part of the cap cover and cap, and also prevents corrosion between the upper edge of the cap of the fire extinguisher and the outer circumferential surface under the cap's flange. Some fire extinguishers are designed to ensure airtightness within the fire extinguisher body by loading packing.

あるいは腐食ガス）によつて螺合部分が腐食して
しまう問題がある。 By the way, fire extinguishers are installed in any place for a long period of time, such as humid areas, coastal areas, or inside factories where metal is prone to corrosion. Merely preventing rainwater from entering from above is not complete. Therefore, if the above-mentioned conventional fire extinguisher is installed in a place with such adverse conditions, the threaded part may be damaged by corrosive substances (rainwater or corrosive gas) that enter from the underside of the cap cover. There is a problem with corrosion.

ツプカバーとキヤツプは遊嵌関係にあるため、こ
のような事態が生じ易い。 Furthermore, in the above-mentioned conventional caps, packing is installed between the tip surface of the flange portion of the cap cover and the outer peripheral surface above the flange portion of the cap to prevent rainwater etc. from entering from above the screwed portion. Therefore, if the cap cover is attached to the cap part eccentrically with respect to the cap, the part of the packing on the opposite side of the eccentric direction will be attached to the top surface of the flange part of the cap cover and the top of the flange part of the cap. Depending on the outer circumferential surface, there is a problem in that the pressure contact is not so great that the sealing force at that part becomes insufficient, and rainwater and the like can enter from above. In particular, since the cap cover and the cap of the fire extinguisher are loosely fitted, such a situation is likely to occur.

問題がある。 In addition, in the conventional fire extinguisher mentioned above, airtightness within the fire extinguisher body is ensured by installing packing between the upper edge of the mouthpiece of the fire extinguisher body and the outer peripheral surface under the flange of the cap. Therefore, when attaching the cap cover to the cap, the packing pressed against the cap's flange is easily damaged by the upper end of the cap, making it difficult to ensure airtightness within the fire extinguisher body. There is.

作業になる問題もある。 In addition, the seal under the flange of this cap is
Since it is not visible, there is no way to know whether the packing has been damaged or whether it is properly sealed, and there is no guarantee that it is sealed. Therefore, in such a configuration, the problem is solved by tightly tightening the threaded part of the cap cover to the threaded part of the cap. If it is too long, the screws will rust, making it difficult to remove the cap cover, and replacing the extinguishing agent will be very troublesome.
