Description

  The present invention relates to a fire extinguisher covering member and a fire extinguisher including the fire extinguisher covering member.

  Conventionally, a fire extinguisher storage container used for a fire extinguisher is manufactured from a metal such as iron, stainless steel, and aluminum. Among them, iron fire extinguishing agent storage containers are sturdy and not easily damaged, and the manufacturing cost is low. Therefore, iron is used for about 90% of fire extinguishers on the market.

  On the other hand, the example of the fire extinguisher provided with the resin-made fire extinguisher storage containers is disclosed. One document discloses a fire extinguisher in which the filling pressure is lowered as much as possible so as to maintain even the low pressure resistance which was a weak point of a resin fire extinguisher storage container (Patent Document) 1). Another document discloses a fire extinguisher using a thin polyethylene terephthalate (PET) waste product used for soft drinks or alcoholic beverages (Patent Document 2).

  As described above, iron extinguishing agent storage containers that are widely used in general are very heavy, causing problems of inconvenience to carry and poor operability, particularly for women, children, and elderly people. In addition, the weight of the metal fire extinguisher is damaged, and there is a problem that the transportation cost for collecting and recycling the fire extinguisher increases.

  Moreover, in the case of iron, although it is an inexpensive fire extinguisher, it is corrosive, so it is necessary to paint the surface of the container and apply a rust prevention treatment. Actually, since this process takes time and effort, it results in an increase in manufacturing cost that cannot be ignored from the unit price of one fire extinguisher. In addition, it is necessary to separate the rust inhibitor from iron for recycling. However, since the process of separating the painted surface takes a considerable amount of time, the work of recycling a metal fire extinguisher storage container typified by iron becomes extremely complicated and its cost increases.

  At first glance, the above-described technical problems due to the metal typified by iron seem to be solved by adopting a resin fire extinguishing agent storage container. However, there are also specific problems caused by the adoption of resin fire extinguishing agent storage containers. That is, when a resin-made fire extinguisher storage container having low resistance to ultraviolet rays or the like is employed, the quality required as a fire extinguisher cannot be maintained depending on the state of deterioration of a portion irradiated with ultraviolet rays. In other words, when resin fire extinguisher storage containers are used, the environment in which each fire extinguisher is placed varies. Differences in speed can occur. If it does so, it may also occur that the performance of a general fire extinguisher is not maintained as expected (for example, 8 years, depending on installation conditions). In addition, fire extinguishers with different environments are rarely placed in close proximity, so even a specialist who regularly checks fire extinguishers should install a plastic fire extinguisher storage container. It is very difficult to determine the deterioration level of a fire extinguisher unit by observing the appearance.

  The present invention greatly contributes to the realization of a fire extinguisher that can easily grasp the degree of deterioration peculiar to a resin-made fire extinguisher storage container only by its appearance, by solving the above-mentioned problems of the prior art.

  The inventor conducted intensive research on a method that can find out the influence of ultraviolet rays, which is one of the weak points, while maintaining the advantages of a plastic fire extinguisher storage container. As a result, the inventor is one of the main causes that makes it difficult for even a specialist in inspection to determine that a fire extinguisher installed in a certain environment is almost uniformly affected by the environment. I focused on it. The inventor has developed a fire extinguisher that can easily grasp the degree of deterioration of a resin-made fire extinguishing agent storage container only by its appearance, not only from its specialists but also from general users from various viewpoints. As a result, the present inventors have succeeded in finding a configuration of a fire extinguisher storage container and a fire extinguisher that can solve the above technical problem. The present invention was created from such a viewpoint.

  One fire extinguisher covering member of the present invention has a mouth portion serving as an opening and is detachably disposed on or above the outer peripheral surface of a fire extinguisher storage container formed by a seamless resin and shields ultraviolet rays. To do.

  According to this fire extinguisher covering member, the amount of ultraviolet rays is different between the part covered with the fire extinguisher covering member and the part not covered with the fire extinguisher covering member in the fire extinguisher storage container. Therefore, since the portion covered with the fire extinguisher covering member and the portion not covered with the fire extinguisher covering member are adjacent to each other, the degree of deterioration or a change with time (hereinafter, collectively referred to as “deterioration degree” in this application). ) Becomes clearer with time. That is, by adopting the above-described configuration, the clarity of the degree of deterioration can be clarified. Thereby, even if it is a fire extinguisher single-piece | unit, the deterioration degree can be easily discriminate | determined only by an external appearance. Moreover, since this fire extinguisher covering member is detachable, the fire extinguisher covering member once peeled off from the outer peripheral surface of the fire extinguisher storage container or from above can be pasted again at the same place. Therefore, a single fire extinguisher covering member can be disposed on or above the outer peripheral surface of the fire extinguisher storage container throughout the service life of the fire extinguisher. That is, by adopting the above-described configuration, it is not necessary to replace the fire extinguisher covering member every time an inspection is performed, so that the inspection burden can be reduced.

  Further, another fire extinguisher covering member of the present invention has the above-mentioned extinguishing agent storage container on or above the outer peripheral surface of the extinguishing agent storage container formed by a seamless resin having a mouth portion serving as an opening. The covering member is disposed so as to cover the entire circumference of at least a part of the side surface and shields ultraviolet rays, and the covering member has a hole or a notch.

  According to this fire extinguisher covering member, the amount of ultraviolet rays is different between the portion of the fire extinguisher storage container that is covered by the fire extinguisher covering member and the portion corresponding to the hole or notch of the fire extinguisher covering member. . Therefore, the difference between the degree of deterioration of the portion covered with the fire extinguisher covering member and the degree of deterioration of the portion corresponding to the hole or notch of the fire extinguisher covering member becomes more apparent with time. Thereby, even if it is a fire extinguisher single-piece | unit, the deterioration degree can be easily discriminate | determined only by an external appearance.

  Further, another fire extinguisher covering member of the present invention has the above-mentioned extinguishing agent storage container on or above the outer peripheral surface of the extinguishing agent storage container formed by a seamless resin having a mouth portion serving as an opening. The covering member is arranged so as to cover the entire circumference of a part of the side surface and shields ultraviolet rays, and the covering member shields 50% or more of any ultraviolet rays having a wavelength of 200 nm or more and 380 nm or less. .

  According to the fire extinguisher covering member, the amount of ultraviolet rays is different between the portion covered with the fire extinguisher covering member and the portion not covered with the fire extinguisher covering member of the fire extinguisher storage container. Therefore, the difference between the deterioration degree of the portion covered with the fire extinguisher covering member and the deterioration degree of the portion not covered with the fire extinguisher covering member becomes clearer with time. Thereby, even if it is a fire extinguisher single-piece | unit, the deterioration degree can be easily discriminate | determined only by an external appearance.

  In addition, one fire extinguisher of the present invention has an opening serving as an opening and is detachably disposed on or above the outer peripheral surface of a fire extinguisher storage container formed by a seamless resin and shields ultraviolet rays. A fire extinguisher covering member is provided.

  According to this fire extinguisher, the amount of ultraviolet rays is different between the part covered by the fire extinguisher covering member and the part not covered by the fire extinguisher covering member of the fire extinguisher storage container. Therefore, since the portion covered with the fire extinguisher covering member and the portion not covered with the fire extinguisher covering member are adjacent to each other, the difference in the degree of deterioration becomes clearer with time. That is, by adopting the above-described configuration, the clarity of the degree of deterioration can be clarified. Thereby, even if it is a fire extinguisher single-piece | unit, the deterioration degree can be easily discriminate | determined only by an external appearance. Moreover, since this fire extinguisher covering member is detachable, the fire extinguisher covering member once peeled off from the outer peripheral surface of the fire extinguisher storage container or from above can be pasted again at the same place. Therefore, a single fire extinguisher covering member can be disposed on or above the outer peripheral surface of the fire extinguisher storage container throughout the service life of the fire extinguisher. That is, by adopting the above-described configuration, it is not necessary to replace the fire extinguisher covering member every time an inspection is performed, so that the inspection burden can be reduced.

  In addition, another fire extinguisher of the present invention has at least one of the above-mentioned fire extinguisher storage containers on or above the outer peripheral surface of a fire extinguisher storage container that has a mouth portion that becomes an opening and is molded by a seamless resin. A covering member that is arranged so as to cover the entire circumference of some side surfaces and shields ultraviolet rays, and the covering member includes a covering member for a fire extinguisher having a hole or a notch.

  According to this fire extinguisher, the amount of ultraviolet rays is different between a part of the fire extinguisher storage container that is covered with the fire extinguisher covering member and a part corresponding to the hole or notch of the fire extinguisher covering member. Therefore, the difference between the degree of deterioration of the portion covered with the fire extinguisher covering member and the degree of deterioration of the portion corresponding to the hole or notch of the fire extinguisher covering member becomes more apparent with time. Thereby, even if it is a fire extinguisher single-piece | unit, the deterioration degree can be easily discriminate | determined only by an external appearance.

  Another fire extinguisher of the present invention has a mouth portion serving as an opening, and is provided on the outer peripheral surface of a fire extinguisher storage container formed by a seamless resin or above the fire extinguisher storage container. A covering member that is arranged so as to cover the entire circumference of the side surface of the part and shields ultraviolet rays, the covering member being used for a fire extinguisher that shields 50% or more of any ultraviolet rays having a wavelength of 200 nm or more and 380 nm or less A covering member is provided.

  According to this fire extinguisher, the amount of ultraviolet rays is different between the part covered by the fire extinguisher covering member and the part not covered by the fire extinguisher covering member of the fire extinguisher storage container. Therefore, the difference between the deterioration degree of the portion covered with the fire extinguisher covering member and the deterioration degree of the portion not covered with the fire extinguisher covering member becomes clearer with time. Thereby, even if it is a fire extinguisher single-piece | unit, the deterioration degree can be easily discriminate | determined only by an external appearance.

  In the present application, the ultraviolet shielding rate refers to a value obtained by measuring the transmittance (%) of each wavelength from 200 nm to 380 nm with a spectrophotometer and subtracting the value of the transmittance from 100.

  According to the fire extinguisher storage container or fire extinguisher of the present invention, it is possible to easily grasp the degree of deterioration due to ultraviolet rays unique to the resin fire extinguisher storage container only from the appearance.

  Embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this description, common parts are denoted by common reference symbols throughout the drawings unless otherwise specified. In the drawings, the elements of this embodiment are not necessarily shown to scale. Moreover, in order to make each drawing easy to see, some reference numerals may be omitted.

<First Embodiment>
FIG. 1 is an overall external view of a fire extinguisher 100 according to the present embodiment. FIG. 2 is a side view of the fire extinguishing agent storage container 11 and the covering member 12, and FIG. 3 is a side sectional view of the fire extinguishing agent storage container 11 and the covering member 12.

  As shown in FIG. 1, the fire extinguisher 100 according to the present embodiment is disposed above a fire extinguisher storage container 11 filled with a fire extinguishing agent 60 (for example, a powder fire extinguishing agent) and an outer peripheral surface of the fire extinguishing agent storage container 11. A covering member 12, a support base 50 that fits into the bottom of the extinguishing agent storage container 11 and supports the extinguishing agent storage container 11, a fire extinguisher hand lever 30 disposed above the extinguishing agent storage container 11, A siphon pipe 70 for guiding the fire extinguisher 60 stored in the fire extinguisher storage container 11 to the fire extinguisher hand lever 30, and a fire extinguisher connected to the siphon pipe 70 so as to be circulated by operating the fire extinguisher hand lever 30. Hose 40.

  The fire extinguisher hand lever 30 includes a lid 31, a fixing lever 32, an activation lever 33, a raising / lowering rod 34, and a safety plug 35. In the present embodiment, when the safety stopper 35 is engaged with the raising and lowering bar 34, the activation lever 33 is fixed in a non-rotatable state with respect to the fixing lever 32. In addition, when the safety plug 35 is released from the engaged state with the raising / lowering rod 34, the activation lever 33 becomes rotatable with respect to the fixed lever 32.

  In addition, as shown in FIGS. 1 to 3, the fire extinguisher storage container 11 in the present embodiment includes a fire extinguisher storage portion 13 and a male screw portion formed in an opening located above the fire extinguisher storage portion 13. 14. The extinguishing agent storage container 11 and the fire extinguisher hand lever 30 are fixed by screwing the male screw portion 14 and the fire extinguisher hand lever 30 together. The fixing means between the extinguishing agent storage container 11 and the fire extinguisher hand lever 30 is not limited to screwing, and known joining means can be applied. Moreover, the fire extinguisher storage container 11 of this embodiment is formed of polyethylene naphthalate (PEN). In addition, as shown in FIGS. 1 to 3, the fire extinguisher storage container 11 of the present embodiment is not formed with a seam like a metal fire extinguisher storage container. In addition, the fire extinguisher storage container 11 of this embodiment is formed only with polyethylene naphthalate (PEN).

  Next, the manufacturing method of the fire extinguisher storage container 11 of this embodiment is demonstrated. The fire extinguisher storage container 11 made of polyethylene naphthalate (PEN) can be produced by a conventionally known resin molding method such as stretch blow molding, melt shaping, etc. Among them, there is no seam and the molding state is good. In addition, stretch blow molding is preferable in that a container having an appropriate thickness can be obtained.

  A film 15 is mounted on the outer peripheral surface of the extinguishing agent storage container 11. The film 15 is composed of a stretchable or heat-shrinkable film. For this reason, the extinguishing agent storage container 11 can be mounted in a state where the film 15 is in close contact with the extinguishing agent storage container 11.

  The film 15 is a composite material in which a pigment is printed on the surface and a protective film for protecting the pigment is formed on the upper layer of the pigment. The protective film constituting a part of the film 15 is generally susceptible to deterioration including chemical changes due to ultraviolet irradiation, and this protective film is likely to deteriorate due to ultraviolet irradiation and easily peel off. For this reason, when the protective film is irradiated with ultraviolet rays, the protective film is peeled off and the pigment is exposed. Here, the pigment includes an organic pigment and an inorganic pigment. Since organic pigments have relatively poor weather resistance, it is considered that organic pigments have properties that are more easily peeled off by ultraviolet rays, wind and rain, etc. than inorganic pigments. For this reason, when an organic pigment is adopted as the pigment, after the protective film is peeled off, the organic pigment is peeled off by being directly exposed to the outside air. Therefore, in this case, the contrast of the degree of deterioration can be emphasized. On the other hand, it is considered that inorganic pigments are coarser than other pigments such as organic pigments, and unevenness appears clearly from the appearance. For this reason, when an inorganic pigment is employed as the pigment, the inorganic pigment is directly irradiated with visible light after the protective film is peeled off. Therefore, in this case, the visible light irradiated on the inorganic pigment is irregularly reflected, so that the contrast due to the change with time can be visually emphasized.

  Here, the covering member 12 is detachably bonded onto the film 15. The covering member 12 has a function of shielding ultraviolet rays. For this reason, the amount of ultraviolet rays is different between the portion of the film 15 that is covered by the covering member 12 and the portion that is not covered by the covering member 12. Therefore, the difference between the degree of deterioration of the part of the film 15 covered by the covering member 12 and the degree of deterioration of the part not covered by the covering member 12 becomes clearer with time. That is, the degree of change in the color of the pigment contained in the film 15, which is considered to be mainly a chemical change due to the irradiation of ultraviolet rays, between the portion covered by the covering member 12 and the portion not covered by the covering member 12 in the film 15. Will be different. As a result, since the portion that has been discolored by ultraviolet irradiation and the portion that has little discoloration are adjacent to each other, the observer can easily determine the degree of newness of the fire extinguisher 100, in other words, the degree of deterioration by just the appearance. Can be determined.

  Moreover, since the coating | coated member 12 can be attached or detached, even if it peels once from the film 15, it can affix on the same place again. Accordingly, the single covering member 12 can be disposed above the film 15 throughout the life of the fire extinguisher 100. That is, since it is not necessary to replace the covering member 12 every time an inspection is performed, the inspection burden can be reduced.

  Hereinafter, a method for determining the degree of deterioration of the fire extinguisher 100 will be specifically described. When determining the degree of deterioration of the fire extinguisher 100 according to the present embodiment, first, the observer peels the removable covering member 12 from the film 15. Next, the color difference between the portion of the film 15 that is covered with the covering member 12 and the portion that is not covered with the covering member 12 is compared and observed. That is, the observer compares the discoloration degree of the portion covered with the covering member 12 with the discoloration degree of the portion not covered with the covering member 12. As described above, the portion of the film 15 that is covered with the covering member 12 receives less ultraviolet light than the portion that is not covered with the covering member 12. Therefore, the discoloration degree of the portion not covered with the covering member 12 (the portion directly receiving the ultraviolet rays) is stronger than the discoloration degree of the portion covered with the covering member 12 in the fire extinguishing film 15. In addition, the difference between the degree of discoloration of the portion of the film 15 that is covered with the covering member 12 and the degree of discoloration of the portion of the film 15 that is not covered with the covering member 12 increases with time. As a result, the observer can easily determine the degree of deterioration of the film 15 only by the appearance only by observing two adjacent areas in one fire extinguisher 100.

  By the way, in order to easily determine the degree of deterioration of the material due to ultraviolet rays only by appearance, the ultraviolet shielding rate of the covering member 12 is 50% or more for ultraviolet rays of any wavelength of 200 nm or more and 380 nm or less. preferable. By adopting this ultraviolet shielding rate, the contrast of the degree of deterioration is emphasized. In addition, the material of the covering member 12 of this embodiment is polyethylene terephthalate (PET). This is because the handleability is good and the burden on the environment can be reduced as compared with vinyl chloride and the like. Further, from the viewpoint of conspicuous contrast of the degree of deterioration, it is more preferable that the ultraviolet shielding rate of the covering member 12 of the present embodiment is 80% or more with respect to ultraviolet rays having any wavelength of 200 nm or more and 380 nm or less, and 200 nm or more. Most preferably, it is 90% or more for ultraviolet rays of any wavelength of 380 nm or less. Furthermore, from the viewpoint that it is possible to repeatedly attach and detach, such as peeling after bonding and bonding after peeling, as an adhesive material for bonding the covering member 12 to the film 15, the acrylate monomer is modified and rebonding after peeling. Adhesives or the like that have properties can be employed.

<Second Embodiment>
FIG. 4 is an overall external view of the fire extinguisher 200 of the present embodiment. FIG. 5 is a side view of the extinguishing agent storage container 11 and the covering member of the present embodiment, and FIG. 6 is a side sectional view of the extinguishing agent storage container 11 and the covering member.

  Except for the point that the fire extinguisher 200 of the present embodiment uses an ultraviolet shielding film 215 as a covering member instead of the film 15 of the first embodiment and does not include the covering member 12 of the first embodiment. The same configuration as that of the first embodiment is provided. Therefore, the description which overlaps with 1st Embodiment is abbreviate | omitted.

  As shown in FIGS. 4 to 6, the ultraviolet shielding film 215 of the present embodiment is mounted on the outer peripheral surface of the fire extinguisher storage container 11. The ultraviolet shielding film 215 is formed of a stretchable or heat-shrinkable film, similar to the film 15 of the first embodiment. For this reason, the ultraviolet shielding film 215 is mounted in a state of being in close contact with the fire extinguisher storage container 11. A hole 216 is formed in the ultraviolet shielding film 215. In addition, since the ultraviolet shielding film 215 of this embodiment transmits visible light, the color of the resin material of the fire extinguisher storage container 11 can be visually recognized. Further, in order to easily determine the deterioration degree of the resin material of the extinguishing agent storage container 11 due to ultraviolet rays, the ultraviolet ray shielding film 215 has an ultraviolet ray shielding rate of any wavelength between 200 nm and 380 nm. Is preferably 50% or more. By adopting this ultraviolet shielding rate, the contrast of the degree of deterioration is emphasized. Moreover, the material of the ultraviolet shielding film 215 of this embodiment is polyethylene terephthalate (PET). This is because the handleability is good and the burden on the environment can be reduced as compared with vinyl chloride and the like. Further, from the viewpoint of conspicuous contrast of the degree of deterioration, it is more preferable that the ultraviolet ray shielding rate of the ultraviolet ray shielding film 215 of the present embodiment is 80% or more with respect to ultraviolet rays having any wavelength of 200 nm to 380 nm. It is most preferable to set it to 90% or more with respect to ultraviolet rays having any wavelength of 380 nm or less.

  When determining the degree of deterioration of the fire extinguisher 200 of the present embodiment, more specifically, the degree of deterioration of the resin material of the fire extinguisher storage container 11, the observer uses the fire extinguisher storage container 11 covered with the ultraviolet shielding film 215. And the difference between the color of the extinguishing agent storage container 11 corresponding to the hole 216 is compared and observed. Here, the resin material constituting the extinguishing agent storage container 11 is considered to cause a chemical reaction and deteriorate when irradiated with ultraviolet rays. This deterioration appears as a change that can be recognized as a visual perception of a color change (for example, yellowing) or a material change (for example, a crack). Therefore, the degree of discoloration (or alteration) differs between the part covered with the coating film 15 and the part corresponding to the hole 216 in the fire extinguishing agent storage container 11. That is, the degree of discoloration (or alteration) of the extinguishing agent storage container 11 corresponding to the hole 216 and the discoloration (or alteration) of the extinguishing agent storage container 11 covered with the ultraviolet shielding film 215 adjacent to the hole 216. ) Is compared. As described above, the portion of the fire extinguisher storage container 11 that is covered with the ultraviolet shielding film 215 is directly irradiated with ultraviolet rays because of the degree of discoloration (or alteration) of the fire extinguisher storage container 11. The degree of discoloration (or alteration) of a part of the extinguishing agent storage container 11 that has been stored becomes stronger. In addition, the degree of discoloration (or alteration) of the part of the extinguishing agent storage container 11 covered by the ultraviolet shielding film 215 and the partial discoloration (or alteration) of the extinguishing agent storage container 11 corresponding to the hole 216. The difference from the degree of increases with time. The observer can easily determine the degree of deterioration of the resin material constituting the extinguishing agent storage container 11 only by observing two adjacent areas in one fire extinguisher 200. Such a fire extinguisher 200 does not require the provision of a separate covering member unlike the fire extinguisher 100 of the first embodiment, so the degree of deterioration can be determined at a glance without removing the covering member 12 during inspection. can do.

  In this embodiment, since the ultraviolet shielding film 215 transmits visible light, the color of the surface of the fire extinguisher storage container 11 covered with the ultraviolet shielding film 215 can be visually recognized. It is not limited to this. Even if the ultraviolet shielding film 215 does not transmit visible light, a difference in the degree of discoloration can be obtained by removing a part of the ultraviolet shielding film 215 in the region adjacent to the hole 216 or by removing a part thereof. Can be easily confirmed.

<Third Embodiment>
FIG. 7 is a side view of the extinguishing agent storage container 11 and the covering member of the present embodiment, and FIG. 8 is a side sectional view of the extinguishing agent storage container 11 and the covering member.

  The fire extinguisher of this embodiment is the first except that the ultraviolet shielding film 315 as a covering member is used instead of the film 15 of the first embodiment, and the covering member 12 of the first embodiment is not provided. The same configuration as that of the embodiment is provided. Therefore, the description which overlaps with 1st Embodiment is abbreviate | omitted.

  As shown in FIGS. 7 and 8, the ultraviolet shielding film 315 of this embodiment is mounted on the outer peripheral surface of the extinguishing agent storage container 11 so as to cover the entire circumference of at least a part of the side surface of the extinguishing agent storage container 11. The More specifically, the ultraviolet shielding film 315 is mounted on the outer peripheral surface of the trunk portion 13a that is a cylindrical region of the extinguishing agent storage portion 13, and a part of the shoulder portion 13b having a curved cross section and one of the bottom portions 13c. Not mounted on the outer peripheral surface of the part. For this reason, the ultraviolet shielding film 315 can be easily attached to the fire extinguisher storage container 11. Furthermore, the ultraviolet shielding film 315 is formed of a stretchable or heat-shrinkable film, similarly to the film 15 of the first embodiment. For this reason, the ultraviolet shielding film 315 can be mounted in a state of being in close contact with the fire extinguisher storage container 11. In order to easily determine the degree of deterioration due to ultraviolet rays only by appearance, it is preferable that the ultraviolet ray shielding film 315 has an ultraviolet ray shielding rate of 50% or more with respect to ultraviolet rays having any wavelength of 200 nm to 380 nm. . By adopting this ultraviolet shielding rate, the contrast of the degree of deterioration is emphasized. In addition, the material constituting the ultraviolet shielding film 315 of this embodiment is polyethylene terephthalate (PET). This is because the handleability is good and the burden on the environment can be reduced as compared with vinyl chloride and the like. Further, from the viewpoint of conspicuous deterioration degree contrast, it is more preferable that the ultraviolet ray shielding film 315 of the present embodiment has an ultraviolet ray shielding rate of 80% or more with respect to ultraviolet rays having any wavelength of 200 nm to 380 nm. It is most preferable to set it to 90% or more with respect to ultraviolet rays having any wavelength of 380 nm or less.

  When discriminating the degree of deterioration of the resin material of the above-described extinguishing agent storage container 11, the observer can determine whether the extinguishing agent storage container 11 covered with the ultraviolet shielding film 315 and a part of the shoulder part 13b or a part of the bottom part 13c.

That is, the degree of discoloration (or alteration) of a part of the shoulder part 13b or a part of the bottom part 13c and the fire extinguishing covered with the ultraviolet ray shielding film 315 adjacent to a part of the shoulder part 13b or a part of the bottom part 13c. The degree of discoloration (or alteration) of the agent storage container 11 is compared. As described above, of the extinguishing agent storage container 11, the shoulder 13 b that has been directly irradiated with ultraviolet rays is more than the degree of discoloration (or alteration) of the extinguishing agent storage container 11 in the portion covered with the ultraviolet shielding film 315. The degree of discoloration (or alteration) of a part or part of the bottom 13c is stronger. In addition, the degree of discoloration (or alteration) of the portion of the extinguishing agent storage container 11 covered with the ultraviolet shielding film 315 and the degree of discoloration (or alteration) of a part of the shoulder portion 13b or a part of the bottom portion 13c. The difference becomes larger with time. The observer can easily determine the degree of deterioration of the resin material constituting the extinguishing agent storage container 11 only by observing two adjacent areas in one fire extinguisher.

  As shown in FIGS. 9 and 10, the covering member 12 of the present embodiment is detachably bonded to the outer peripheral surface of the extinguishing agent storage container 11.

  When determining the deterioration degree of the resin material of the fire extinguishing agent storage container 11 having the above-described configuration, first, the observer peels the removable covering member 12 from the fire extinguishing agent storage container 11. Next, in the fire extinguisher storage container 11, the difference in color between the portion covered with the covering member 12 and the portion not covered with the covering member 12 is compared and observed. That is, the degree of discoloration (or alteration) of the portion covered with the covering member 12 is compared with the degree of discoloration (or alteration) of the portion not covered with the covering member 12. As described above, the covering member 12 that has been directly irradiated with ultraviolet rays rather than the degree of discoloration (or alteration) of the extinguishing agent storage container 11 in the portion of the extinguishing agent storage container 11 that is covered with the covering member 12. The degree of discoloration (or alteration) of the portion not covered with is stronger. In addition, the degree of discoloration (or alteration) of the part of the extinguishing agent storage container 11 covered by the covering member 12 and the discoloration (or alteration) of the part of the extinguishing agent storage container 11 not covered by the covering member 12. ) Increases with the passage of time. The observer can easily determine the degree of deterioration of the resin material constituting the extinguishing agent storage container 11 only by observing two adjacent areas in one fire extinguisher. If it is such a fire extinguisher, since it is not necessary to provide the film 15 separately like the fire extinguisher 100 of 1st Embodiment, the cost of the film 15 can be reduced.

  By the way, polyethylene terephthalate (PET) is used as the material of the covering member 12 in the first embodiment, the ultraviolet shielding film 215 in the second embodiment, and the ultraviolet shielding film 315 in the third embodiment. However, the present invention is not limited to this. For example, even if vinyl chloride is employed as the material of the covering member 12 in the first embodiment, the ultraviolet shielding film 215 in the second embodiment, and the ultraviolet shielding film 315 in the third embodiment, at least the present invention. Some effects are expected. However, considering the influence on the environment, it is preferable to use polyethylene terephthalate (PET).

  In the first embodiment described above, the film 15 is mounted on the outer peripheral surface of the extinguishing agent storage container 11. However, as in the present embodiment, the outer peripheral surface of the extinguishing agent storage container 11 without the film 15. The covering member 12 may be directly adhered to the surface. However, it is preferable to attach the film 15 from the viewpoint of protection of the extinguishing agent storage container 11 and / or ease of printing and decoration for improving the design.

  Further, in the first embodiment described above, the covering member 12 is bonded so that the film 15 as a member having a different ultraviolet shielding rate is vertically arranged in the four directions of up, down, left, and right. However, the present invention is not limited to this. . The covering member 12 may be bonded to the upper end or the lower end of the film 15, and the film 15 and the fire extinguishing agent storage container 11 as members having different ultraviolet shielding rates may be disposed on the entire periphery of the covering member 12. Similarly, you may adhere | attach the coating | coated member 12 so that the film 15 and the fire extinguisher storage container 11 may be bridge | crosslinked. The shape of the covering member 12 may be a circle, a polygon, or a combination of a circle and a polygon, and the shape is not particularly limited. In order to improve the designability, it is a preferable aspect that the covering member 12 having an interesting shape is employed.

  In the first embodiment described above, examples of organic pigments and inorganic pigments are given as pigments constituting a part of the film 15, but the invention is not limited thereto. Other pigments may be employed as the pigment constituting part of the film 15. However, it is preferable to employ organic pigments or inorganic pigments from the standpoint of conspicuous deterioration degree contrast. Further, although it depends on the surrounding environment, it is considered that the contrast due to peeling of organic pigment due to wind and rain etc. is clearer than the contrast due to irregular reflection of visible light caused by the unevenness of the inorganic pigment. For this reason, it is preferable that an organic pigment is employed as the pigment constituting the film 15.

  Even if a material on which no pigment is printed is adopted as the film 15, the deterioration degree of the fire extinguisher storage container 11 itself can be easily determined only by the appearance. That is, the difference between the degree of deterioration of the portion where the covering member 12 is disposed above the extinguishing agent storage container 11 and the degree of deterioration of the portion where the covering member 12 is not disposed above is more apparent with time. It becomes clearer. More specifically, it is considered that a chemical change is mainly caused by irradiation of ultraviolet rays between a portion where the covering member 12 is disposed above the extinguishing agent storage container 11 and a portion where the covering member 12 is not disposed above the portion. The degree of color change (for example, yellowing) of the fire extinguisher storage container 11 or the degree of material alteration (for example, cracking) varies. As a result, the portion of the extinguishing agent storage container 11 that has been discolored (or altered) by ultraviolet irradiation and the portion that has less discoloration (or alteration) are visually recognized in a state where they are adjacent. For this reason, the observer can easily determine the degree of deterioration of the fire extinguisher 100 only from the appearance. However, in general, the progress of the discoloration of the pigment is faster than the progress of the discoloration (or alteration) of the resin material constituting the extinguishing agent storage container 11. For this reason, it is preferable that the composite material on which the pigment is printed is employed as the film 15 in that the contrast of the deterioration degree is more conspicuous than the material on which the pigment is not printed is employed as the film 15.

  Further, in the second embodiment described above, the hole 216 is formed so that the extinguishing agent storage container 11 as a member having different ultraviolet shielding rates is uniformly present in the four directions of up, down, left, and right. It is not limited. Furthermore, the shape of the hole 216 is a circle, a polygon, or a combination of a circle and a polygon, and the shape is not particularly limited. In order to improve the designability, it is a preferable aspect that the hole 216 having an interesting shape is employed.

  In the second and third embodiments described above, the ultraviolet shielding films 215 and 315 are directly mounted on the outer peripheral surface of the fire extinguishing agent storage container 11, but the present invention is not limited to this. The ultraviolet shielding films 215 and 315 may be mounted on the outer peripheral surface of the extinguishing agent storage container 11 after a film having no ultraviolet shielding performance is mounted. By adopting this configuration, it is possible to prevent damage to the surface of the extinguishing agent storage container 11. However, it is preferable that the ultraviolet shielding films 215 and 315 are directly mounted on the outer peripheral surface of the fire extinguishing agent storage container 11 in that the film material and attachment are required.

  Moreover, in the above-mentioned 3rd Embodiment, although the ultraviolet-ray shielding film 315 is mounted | worn on the outer peripheral surface of the trunk | drum 13a which is a cylindrical area | region of the fire extinguisher storage part 13, it is not limited to this. You may mount | wear on the outer peripheral surface of the shoulder part 13b and the bottom part 13c from which a cross section becomes a curved surface shape. That is, if it is mounted on the outer peripheral surface of the fire extinguishing agent storage container 11 so as to cover at least a part of the entire circumference, the same effect as that of the third embodiment is obtained.

  Moreover, in the above-mentioned 2nd Embodiment and 3rd Embodiment, although the structure which is not provided with the film 15 of 1st Embodiment is employ | adopted, it is not limited to this. A configuration may be employed in which the film 15 on which the pigment is printed is disposed below the ultraviolet shielding film 215 and above the fire extinguishing agent storage container 11 in the second embodiment. Moreover, it is also a preferable aspect that the configuration in which the film 15 on which the pigment is printed is disposed below the ultraviolet shielding film 315 and above the fire extinguisher storage container 11 in the third embodiment. By adopting such a configuration, the contrast of the degree of deterioration can be further emphasized.

  In addition, in each above-mentioned embodiment, although the covering member, the hole, or the ultraviolet shielding film was disposed at one place, the present invention is not limited to this. It is also a preferable aspect that a plurality of covering members, holes, or ultraviolet shielding films are arranged at positions separated from each other (for example, at equal intervals). Depending on the installation environment of the fire extinguisher, there is a possibility that the covering member, the hole, or the ultraviolet shielding film is located in a place where no ultraviolet ray is irradiated. Therefore, by arranging them at a plurality of locations, it is possible to avoid a situation in which no ultraviolet rays are irradiated to the covering member, the hole, or the ultraviolet shielding film that serves as an index for determining the degree of deterioration. As a specific example, FIG. 11 shows a fire extinguisher 150 which is a modified example of the first embodiment.

  Furthermore, in each above-mentioned embodiment, although polyethylene naphthalate is employ | adopted as resin which comprises the fire extinguisher storage container 11, it is not limited to this. For example, polyethylene terephthalate, a polyester resin obtained by polycondensation using mainly naphthalenedicarboxylic acid or terephthalic acid as a dicarboxylic acid component, ethylene glycol or butanediol as a diol component, or these polyester resins. Even if the material is adopted as the material of the extinguishing agent storage container, it is considered that at least a part of the effect of the present invention is exhibited. In other words, it is considered that at least a part of the effects of the present invention can be achieved with a copolyester resin.

  Moreover, as an example of the material of the fire extinguisher storage container 11 that can be adopted, polyolefin such as polyethylene or polypropylene, polyphenylene sulfide, polystyrene, or polycarbonate can be given. However, among all the materials described above, it is preferable from the viewpoint of strength that polyethylene terephthalate (PET) or polyethylene naphthalate (PEN) is employed. Moreover, in order to improve transparency, it is preferable to employ polyethylene naphthalate (PEN) alone or a blend material mainly composed of polyethylene naphthalate (PEN) and subordinate to polyethylene terephthalate (PET). Furthermore, from the viewpoints of transparency, strength, and gas barrier properties, it is most preferable that polyethylene naphthalate (PEN) is employed alone. That is, by adopting polyethylene naphthalate (PEN), a high-strength fire extinguisher storage container can be obtained with higher accuracy while maintaining appropriate transparency.

  The kind of fire extinguisher with which the fire extinguisher storage container of the fire extinguisher of each of the above embodiments is filled is not particularly limited. Any known extinguishing agent can be employed as long as it does not affect the resin constituting the extinguishing agent container. For example, it can be used as a powder fire extinguisher. Moreover, what was proposed conventionally can be employ | adopted suitably about the filling method of a fire extinguisher, and the material, shape, etc. of components, such as a hose and a nozzle.

  Moreover, as a radiation method of the extinguishing agent, either a pressurization type or a pressure accumulation type can be adopted. However, each of the above-described embodiments is a pressure-accumulating fire extinguisher, and it is worthy to note that it can be applied to a high-pressure fire extinguisher equivalent to or higher than that of a conventional fire extinguisher. Further, the resin constituting the fire extinguisher storage container can be appropriately blended with known additives such as a light stabilizer, an ultraviolet absorber and an anti-aging agent in order to prevent discoloration and improve weather resistance. As described above, modifications that exist within the scope of the present invention are also included in the claims.

  INDUSTRIAL APPLICABILITY The present invention can be widely used as a fire extinguisher covering member and a fire extinguisher for discriminating deterioration of a fire extinguisher storage container only by its appearance.
