no. 1 Embodiment approach

[0060] figure 1 It is a general external view of the fire extinguisher 100 of this embodiment. figure 2 is a front view of the fire extinguishing agent storage container 10, image 3 It is a front cross-sectional view of the fire extinguishing agent storage container 10 . Furthermore, in figure 2 In the figure, for the sake of convenience, a broken line and a solid line are provided for describing the location of the fire extinguishing agent storage container 10 . In addition, in image 3 In the figure, for the sake of convenience, arrows showing the wall thickness of the fire extinguishing agent storage container 10 and broken lines extending the cross-sectional shape of the mouth portion 91 to indicate the wall thickness of the mouth portion 91 are provided.

[0061] like figure 1As shown, the fire extinguisher 100 of this embodiment has: a fire extinguishing agent storage container 10, which contains a fire extinguishing agent 60 (such as a powder fire extinguishin...

no. 2 Embodiment approach

[0085] The fire extinguisher 200 of the present embodiment includes a fire extinguishing agent storage container 20 . Here, in addition to the titanium dioxide (TiO2) for pigments contained in the fire extinguishing agent storage container 20 2 ) has the same configuration as that of the fire extinguisher 100 of the first embodiment except that the pigment perone-based red contained in the fire extinguishing agent storage container 10 of the first embodiment is replaced. Therefore, the overlapping description with the first embodiment is omitted.

[0086] In addition, the fire extinguisher 200 of the present embodiment is provided with titanium dioxide (TiO2) containing a pigment. 2 ) of polyethylene naphthalate (PEN) formed fire extinguishing agent storage container 20. Specifically, the fire extinguishing agent storage container 20 of the present embodiment is formed of polyethylene naphthalate (PEN) mixed with a master batch (a substance in which a pigment and PEN are mix...

Embodiment approach

[0094] The type of the fire extinguishing agent contained in the fire extinguishing agent storage container of the fire extinguisher of each of the above-described embodiments is not particularly limited. Any known fire-extinguishing agent can be used as long as it does not affect the resin constituting the fire-extinguishing agent container. For example, it can also be used as a powder fire extinguisher. In addition, regarding the storage method of the fire-extinguishing agent, the material and shape of components such as hoses and nozzles, and the like, existing ones can be appropriately used.

[0095] In addition, in each of the above-described embodiments, the first and second embodiments form the fire-extinguishing agent storage container using a resin in which a master batch is mixed. Here, a known cover film or a film containing a known pigment may be arranged on the outer peripheral surface of the fire extinguishing agent storage container. For example, films with de...

Abstract

One disclosed fire extinguishing agent storage vessel (10) is the fire extinguishing agent storage vessel (10) of a fire extinguisher (100) and is seamlessly molded, except for an aperture, using a pigmented resin. In addition, gas permeability when the aforementioned aperture has been sealed is not more than 3.22 10-7 ((Pam3mm) / (cm2sMPa)). Provided thereby are an extinguishing agent storage vessel that is lightweight and gas-impermeable, i.e., which features high pressure storage characteristics, and a fire extinguisher that is equipped with the extinguishing agent storage vessel.

Description

technical field [0001] The present invention relates to a resin-made fire extinguishing agent storage container and a fire extinguisher provided with the fire extinguishing agent storage container. Background technique [0002] Historically, fire extinguishing agent storage containers for fire extinguishers have been made of metals such as iron, stainless steel, and aluminum. Among them, iron fire extinguishing agent storage containers are strong, not easily damaged, and have low manufacturing cost. Therefore, the current situation is that about 90% of fire extinguishers on the market use iron fire extinguishing agent storage containers. [0003] On the other hand, an example of a fire extinguisher provided with a resin-made fire extinguishing agent storage container is also disclosed. One document discloses a fire extinguisher in which the filling pressure is reduced as much as possible to maintain a resin-made fire-extinguishing agent storage container with low pressure r...
