Description

  The present invention relates to a fire extinguisher. In more detail, this invention relates to the fire extinguisher provided with the resin-made fire extinguisher storage containers.

  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). The applicant of the present application has also proposed a fire extinguisher with improved practicality such as strength and a part of the fire extinguisher, unlike conventional resin fire extinguishing agent storage containers (Patent Documents 3 to 8). However, when sending out a fire extinguisher using a resin fire extinguisher storage container to the market, various technical problems which have not been envisaged until now have newly emerged.

Japanese Utility Model Publication No. 56-160560 JP-A-9-313634 International Publication No. 2008/133176 Pamphlet JP 2010-200185 A JP 2010-2000816 A JP 2010-222105 A JP 2010-221006 A JP 2010-221007 A

  As mentioned above, fire extinguishers with iron fire extinguishing agent storage containers that are widely used are very heavy, especially for women, children, and elderly people. It was generated.

  At first glance, the above-mentioned technical problem for the metal represented by iron seems to be solved by adopting a plastic fire extinguisher storage container. However, in reality, a fire extinguisher storage container that requires several years to 10 years or more as the expiration date, such as a commonly used metal fire extinguisher, maintains the light weight of the entire container. However, it is not easy to form the resin alone.

  Based on such circumstances, the applicant of the present application has so far proposed various resin-made fire extinguishing agent storage containers that have the advantage that the remaining amount of the extinguishing agent can be visually recognized while having higher strength. . However, since the contents can be visually recognized, a technical problem that has not been conscious of before has emerged. In other words, it is sold as a mass-produced product, and as a result, it will be used by many people in many places, so it is simply a resin fire extinguisher storage container with improved weather resistance and strength However, the existence and handling of the contents that can be visually recognized need to be optimized and highly functional from the technical point of view. And the technical consideration about the visually recognized accommodation further enhances the attractiveness as one product.

  Specifically, until now, if the siphon tube has been designed to meet the performance requirements of conventional fire extinguishers, for example, the capacity of residual extinguishing agent when using a fire extinguisher. There was no problem as a mass-produced product. As a result, the requirements for the verticality of the siphon tube, in other words, the proximity of the siphon tube to the bottom of the fire extinguisher storage container, were not so severe as long as the above-described requirements were satisfied.

  However, the applicant of the present application has conducted a thorough investigation and analysis of a fire extinguisher that employs a resin fire extinguisher storage container that has translucency, in other words, the contents can be visually recognized, in view of mass production. It became clear that the siphon tube connected to the lid body (also referred to as a valve case) and the siphon tube joint is conspicuous unexpectedly in appearance. Therefore, if no consideration is given to the siphon tube and its peripheral parts, which have heretofore been of no concern for general users, a translucent resin fire extinguisher storage container is required. It will affect the reliability and quality as a fire extinguisher.

  The present invention greatly contributes to improving the reliability and quality of a fire extinguisher including a resin-made extinguishing agent storage container having translucency by solving the above technical problems.

  As described above, the inventors of the present application strongly recognized that the siphon tube in the resin-made extinguishing agent storage container having translucency is conspicuously conspicuous. That is, the inventors of the present application, if the siphon tube is not arranged vertically or parallel to the ridgeline of the trunk of the fire extinguisher storage container, the owner of the fire extinguisher, the user, or the intended use person (hereinafter, It was found that “users, etc.” are generally anxious about the displacement of the siphon tube. In the event of a disaster accompanied by a fire, it is not preferable to give such a sense of anxiety to the user or the like because it may hinder appropriate initial fire fighting. On the other hand, the inventors of the present application have also found out that the user can use such a fire extinguisher without feeling particularly uneasy if the deviation is not conspicuous in appearance. Therefore, the inventors of the present application have made improvements by paying attention to the siphon tube itself, and when using a resin-made extinguishing agent storage container having translucency, the inclination of the siphon tube of the conventional level temporarily occurred. Even so, we created a fire extinguisher that does not unnecessarily impair the reliability of users, etc., and is unlikely to cause operational problems. The present invention was created from such a viewpoint.

  One fire extinguisher of the present invention includes a fire extinguisher storage container that is molded seamlessly using a resin and has a visible light transmittance of 5% to 95%. Further, in this fire extinguisher, the visible light transmittance of the siphon tube accommodated in the above-mentioned fire extinguisher storage container is 5% or more and 95% or less.

  According to this fire extinguisher, a translucent siphon tube having a visible light transmittance of 5% to 95% is accommodated in a fire extinguisher storage container having a visible light transmittance of 5% to 95%. Yes. Therefore, when the fire extinguisher storage container has the above-described moderate translucency due to the presence of the translucent siphon tube, the presence of the siphon tube can be made inconspicuous. As a result, even if an existing siphon tube joint is used, in other words, even if a conventional siphon tube tilt occurs, the user of the fire extinguisher should be anxious. It can be remarkably reduced, and hindering initial fire extinguishing due to appearance can be prevented. That is, according to this fire extinguisher, the reliability and quality of a fire extinguisher including a resin-made fire extinguisher storage container having translucency can be improved.

  Another fire extinguisher of the present invention includes a fire extinguisher storage container that is molded seamlessly using the first resin and has a visible light transmittance of 5% to 95%. Further, in this fire extinguisher, the visible light transmittance of the siphon tube accommodated in the above-described fire extinguisher storage container is 5% or more and 95% or less, and the siphon tube is molded using the second resin.

  According to this fire extinguisher, in a fire extinguisher storage container having a visible light transmittance of 5% or more and 95% or less, the visible light transmittance is 5% or more and 95% or less. The siphon tube is housed. Therefore, when the fire extinguisher storage container has the above-described moderate translucency due to the presence of the translucent siphon tube, the presence of the siphon tube can be made inconspicuous. As a result, even if an existing siphon tube joint is used, in other words, even if a conventional siphon tube tilt occurs, the user of the fire extinguisher should be anxious. It can be remarkably reduced, and hindering initial fire extinguishing due to appearance can be prevented. That is, according to this fire extinguisher, the reliability and quality of a fire extinguisher including a (first) resin fire extinguisher storage container having translucency can be improved. Furthermore, since this fire extinguisher has not only a (1) resin fire extinguisher storage container, but also a (2) resin siphon tube, when the fire extinguisher is discarded or recycled, the amount of waste is reduced. Can be achieved. In this fire extinguisher, the first resin and the second resin may be the same material.

Further, another fire extinguisher of the present invention includes a fire extinguisher storage container that is seamlessly molded using a resin containing a pigment and has a visible light transmittance of 5% to 85%. Moreover, this fire extinguisher, the hue of the reflected light of the siphon tube to be accommodated in the above-mentioned fire extinguishing agent storage vessel, which is of a hue similar colors of the reflected light of the foregoing pigments.

  According to this fire extinguisher, a reflected light having a color similar to the hue of the reflected light of the pigment is emitted into a fire extinguisher storage container made of a resin containing a pigment and having a visible light transmittance of 5% to 85%. A siphon tube is housed. Therefore, the presence of the siphon tube that emits such reflected light can make the presence of the siphon tube inconspicuous even when the extinguishing agent storage container has translucency. As a result, even if an existing siphon tube joint is used, in other words, even if a conventional siphon tube tilt occurs, the user of the fire extinguisher should be anxious. It can be remarkably reduced, and hindering initial fire extinguishing due to appearance can be prevented. That is, according to this fire extinguisher, the reliability and quality of a fire extinguisher including a resin-made fire extinguisher storage container having translucency can be improved.

  By the way, in this application, “hue” represents a hue and a color type. Further, in the present application, “reflected light of the same color as the hue of reflected light of the pigment” is not limited to the case where the spectral characteristics of the coloring component (pigment) are strictly the same, and generally (red (Red) ), Yellow (Green), green (Blue), blue (Purple), and the like, it means reflected light in a range that can be called the same color in the normal color concept. “Coloring materials” refers to materials that add color, and coloring materials, such as pigments, paints, and printing inks.

  According to one fire extinguisher of the present invention, the presence of the siphon tube can be made inconspicuous even if the fire extinguisher storage container has translucency. As a result, even if an existing siphon tube joint is used, in other words, even if a conventional siphon tube tilt occurs, the user of the fire extinguisher should be anxious. It can be remarkably reduced, and hindering initial fire extinguishing due to appearance can be prevented.

<First Embodiment>
FIG. 1 is a perspective view of a fire extinguisher 100 in the present embodiment . Also, FIG. 2A is a side view of a fire extinguishing agent storage vessel 10, which is part of the fire extinguisher 100 according to this embodiment, FIG. 2B is a cross-sectional view of the fire extinguishing agent storage vessel 10. FIG. 3A is an enlarged cross-sectional view of a part of the fire extinguisher showing a state in which the siphon pipe joint and the siphon pipe are fitted in the mouth of the fire extinguisher storage container in the present embodiment. FIG. 3B is a cross-sectional view of a part of the fire extinguisher showing an aspect of a state in which the conventional siphon tube 970 is tilted. In addition, FIG. 4A is an enlarged side view of the lid body 31 to which the activation lever 33 in the present embodiment is not engaged, and FIG. 4B is an enlarged view of the lid body 31 to which the activation lever 33 in the present embodiment is engaged. It is a side view.

  First, the structure and function of the fire extinguisher storage container 10, the siphon pipe joint 40, and the siphon pipe 70 in the fire extinguisher 100 will be described.

  As shown in FIG. 1, FIG. 2A, and FIG. 2B, the fire extinguisher storage container 10 of the present embodiment includes an opening 13, but is not formed with a seam like a metal fire extinguisher storage container. Moreover, the fire extinguisher storage container 10 includes a fire extinguisher storage portion 11 and a male screw portion 12 formed in an opening 13 located at the upper portion of the fire extinguisher storage portion 11. After the extinguishing agent 60 (for example, powder extinguishing agent or neutral strengthening liquid) is accommodated in the extinguishing agent storage container 10, the male screw portion 12 and the lid body 31 to which the start lever 33 is not engaged are screwed together. By doing so, the space in the extinguishing agent storage container 10 is ideally sealed. In FIG. 2A, for the sake of convenience, a broken line and a solid line are provided for explaining the part of the extinguishing agent storage container. Further, the fixing means for the extinguishing agent storage container 10 and the lid 31 is not limited to the above-described screwing, and known joining means can be applied. The fire extinguisher storage container 10 of the present embodiment is made of a resin containing a pigment (polyethylene naphthalate (PEN)) and is erected by a support base 50 fitted to a bottom portion 94 having a curved surface, as will be described later. Supported as possible.

2B, for convenience, an arrow for indicating the thickness of the extinguishing agent storage container 10 and a broken line for extending the cross-sectional shape of the mouth portion 91 are provided to display the thickness of the mouth portion 91. ing. The thickness (T ₁ ) of the mouth portion 91 of the extinguishing agent storage container 10 of the present embodiment is 2 mm or more and 8 mm or less. Further, the wall thickness (T ₂ ) of the shoulder portion 92 whose outer diameter increases (becomes a curved surface in the present embodiment) as it goes in the depth direction of the extinguishing agent storage container 10 is 1.2 mm or more and 12 mm or less. Further, the thickness (T ₃ ) of the cylindrical body portion 93 is 1.2 mm or more and 1.9 mm or less, and the thickness (T ₄ ) of the bottom portion 94 having a curved surface is 1.2 mm or more and 12 mm or less. .

  In addition, it is preferable that the thickness of the trunk | drum 93 of the fire extinguisher storage container 10 of this embodiment is 0.9 mm or more and 5 mm or less. If the thickness of the resin is less than 0.9 mm, the strength required for a fire extinguishing agent storage container (for example, a pressure resistance of 2.4 MPa) increases, whereas if it is thicker than 5 mm, This is because the possibility of achieving the advantages of the resin-based fire extinguisher storage container that is not economically preferable and can visually recognize the fire extinguisher as the contents increases. According to the above viewpoint, the thickness of the body portion 93 is more preferably 0.9 mm or more and 3 mm, and further preferably 1 mm or more and 3 mm or less.

  Next, as shown in FIG. 3A, the siphon tube 70 of the present embodiment is inserted densely (closely) from the insertion port 41 of the siphon tube joint 40 to the locking portion 42. Further, the siphon pipe joint 40 of the present embodiment includes an annular seal portion 46 sandwiched between the mouth portion 91 of the extinguishing agent storage container 10 and a valve case (not shown), and an inner peripheral side of the seal portion 46. And a tubular tube holding portion 45 provided with the aforementioned locking portion 42.

  Here, since the siphon pipe joint 40 of the present embodiment is made of rubber (for example, manufactured by NBR), the siphon pipe is within a range that does not impair the sealing performance due to the influence of vibration or the like when the fire extinguisher is transported by a vehicle or the like. The orientation of the joint 940 may shift. As a result, as shown in FIG. 3B, the siphon tube 970 is inclined with respect to the ridgeline of the trunk portion of the extinguishing agent storage container, and the position of the lower end 971 is changed, and in some cases, the state is maintained as such. Sometimes. Conventionally, when the extinguishing agent storage container 910 has translucency as in the present embodiment, the inclination of the siphon tube 970 is visually recognized from the outside through the extinguishing agent storage container 910. As a result, the user or the like has anxiety about the quality of the fire extinguisher 910. That is, when the conventional siphon tube and the siphon tube joint are employed, a new problem with the siphon tube may occur, in addition to the advantage that the remaining amount of the conventional extinguishing agent can be visually recognized from the outside.

  However, the siphon tube 70 of the present embodiment is molded using a resin (for example, a light-transmitting ABS resin (that is, a copolymer synthetic resin of acrylonitrile, butadiene, styrene)). ing. In addition, the visible light transmittance is 5% or more and 95% or less. Moreover, the visible light transmittance | permeability of the fire extinguisher storage container 10 of this embodiment is 5% or more and 85% or less. Therefore, even if the siphon tube 70 is inclined with respect to the ridgeline of the trunk portion of the extinguishing agent storage container 10 for some reason as described above, the state becomes less noticeable when viewed from the outside. As a result, it is possible to significantly reduce the anxiety of the user of the fire extinguisher 100 and to prevent the initial fire extinguishing due to the appearance.

  In addition, if the visible light transmittance | permeability of the fire extinguisher storage container 10 of this embodiment is 85% or less, it will become difficult to see the adhesion to the wall surface of the fire extinguisher 60 accommodated, and the place where the fire extinguisher 100 is installed is The surrounding beauty is not noticeably lost. In addition, if the visible light transmittance of the fire extinguisher storage container 10 of the present embodiment is 85% or less, the user's anxiety is not caused excessively in relation to the visibility of the siphon tube 70. be able to.

  On the other hand, when the visible light transmittance of the fire extinguishing agent storage container 10 is less than 5%, it becomes difficult to check the remaining amount of the fire extinguishing agent 60 in an emergency, so that the practicality is inferior. Therefore, by maintaining appropriate transparency in the above-mentioned range, practicality, aesthetic appearance, and reliability are harmonized. In addition, the visible light transmittance of the fire extinguisher storage container 10 is more preferably 5% or more and 75% or less, and a further preferable range is 20% or more and 70% or less. Within this range, harmony with the surrounding aesthetics can be further achieved, and it is possible to further reduce the anxiety of the user or the like in relation to the visibility of the siphon tube 70. From the viewpoints described above, the total light transmittance of the fire extinguisher storage container 10 of the present embodiment is preferably 5% or more and 75% or less.

  Moreover, the difference between the visible light transmittance of the siphon tube 70 and the visible light transmittance of the extinguishing agent storage container 10 is not particularly limited. However, when the extinguishing agent storage container 10 has a lower visible light transmittance than the siphon tube 70, the visible light transmittance of the siphon tube 70 is smaller than that of the extinguishing agent storage container 10. It is preferable to mold so that the difference falls within the range of 90% or less. On the other hand, when the siphon tube 70 has a lower visible light transmittance than the fire extinguisher storage container 10, the visible light transmittance of the siphon tube 70 is compared with the visible light transmittance of the fire extinguisher storage container 10. It is preferable to mold so that the difference falls within the range of 30% or less. By setting the above-mentioned range, it is possible to more significantly reduce the anxiety of the user or the like. When the visible light transmittance of the siphon tube 70 is lower than that of the fire extinguisher storage container 10, the difference between the visible light transmittance of the siphon tube 70 and the visible light transmittance of the fire extinguisher storage container 10 is 20%. If the following, the above-described effects are further improved. From the viewpoint that it is possible to more significantly reduce the anxiety of the user or the like, even if any visible light transmittance is relatively low, the most preferable difference is 10% or less. .

  By the way, when confirming the achievement degree of weight reduction of the fire extinguisher 100 of this embodiment, the weight as a whole could be reduced to about 70% as compared with a fire extinguisher including a conventional iron fire extinguisher storage container. By realizing the light weight as a fire extinguisher, it is possible to provide a situation where anyone can easily use fire extinguishers regardless of age or gender at the time of a fire and can easily perform fire extinguishing activities.

  Next, the structure and function of the lid 31 and the hose 20 will be described. As shown in FIG. 1, FIG. 4A, and FIG. 4B, the lid body 31 of this embodiment is integrally molded by a known method using a resin (specifically, 6-nylon). A female screw portion (not shown) is formed inside the lid 31. As described above, the lid 31 is attached to the extinguishing agent storage container 10 by screwing the female screw part with the male screw part 12 formed in the extinguishing agent storage container 10. Further, the lid 31 and the fixing lever 31f are integrally formed. The lid 31 includes an activation lever engaging portion 31 a for engaging with the activation lever 33 and a raising / lowering hook engaging portion 31 b for engaging with the raising / lowering rod 34. In addition, the lid body 31 is provided with a sponge-like gripping portion 22 having a large outer diameter so as to be easily held by humans, and a hose fixing portion 31c for fixing the distal end of a flexible hose 20 made of a crosslinked polyethylene resin. It has.

  By connecting to the siphon pipe joint 40 through the connection part 31d of the lid body 31, a flow path communicating from the siphon pipe 70 through the siphon pipe joint 40 to the hose fixing part 31c is formed. Among the flow paths, a part of the flow path 31e in the lid 31 is provided with a metal (specifically, for allowing the extinguishing agent 60 scheduled to be stored in the extinguishing agent storage container 10 to flow to the hose 20 (specifically, , Brass) valve rod (valve) 32 is arranged to be freely opened and closed using a spring. Further, a known hook-and-loop fastener 24 for fixing the tip of the hose 20 is provided at the tip of the hose 20 and a part of the trunk portion 93 of the extinguishing agent storage container 10.

  FIG. 5 is a perspective view showing the activation lever 33 of the present embodiment. FIG. 6 is a perspective view showing an example of the safety stopper 35. The activation lever 33 of this embodiment is integrally molded by a known method using resin (specifically, 6-nylon). The activation lever 33 includes a lever portion 33a, a thin portion 33b, and a lid engaging portion 33c. The activation lever 33 is connected to the lid 31 by engaging the lid engaging portion 33 c and the activation lever engaging portion 31 a of the lid 31. The lever portion 33a includes a first opening 33d into which a fitting rod 35c of the safety plug 35 described later is fitted, and a second opening 33e through which the engaging projection 35a and the projection 35b of the safety plug 35 pass. The thin portion 33b is formed so thin that it can be bent by applying a pressing force. When a pressing force is applied to the lever portion 33a of the activation lever 33, the thin portion 33b bends without being able to withstand this pressing force. When the thin portion 33b is bent in this manner, the activation lever 33 rotates with respect to the lid 31 around the thin portion 33b.

  As shown in FIG. 6, the insertion rod 35 c of the safety plug 35 has a length that can be inserted into the first opening 33 d provided in the activation lever 33 and the opening provided in the raising / lowering rod 34. Further, the engagement protrusion 35 a has a shape that can be engaged with the raising / lowering rod 34 through the second opening 33 e provided in the activation lever 33. When the fitting rod 35c of the safety plug 35 is fitted into the activation lever 33 and the raising / lowering rod 34, and the engagement protrusion 35a is engaged with the raising / lowering rod 34, the raising / lowering rod 34 and the activation lever 33 cannot be rotated. It becomes a state. On the other hand, when the safety stopper 35 is removed from the activation lever 33 and the raising / lowering rod 34, the raising / lowering rod 34 and the activation lever 33 become rotatable.

  In the present embodiment, the raising / lowering rod 34 is also integrally molded by a known method using resin (specifically, 6-nylon), like the start lever 33. Further, the raising / lowering bar 34 includes a thin portion 34a and a safety plug engaging portion 34b, and also includes an opening (not shown) into which the insertion rod 35c of the safety plug 35 is inserted. The raising / lowering rod 34 is connected to the lid 31 by engaging the lower end of the raising / lowering rod 34 with the raising / lowering rod engaging portion 31 b of the lid 31. The thin portion 34a is formed to be thin enough to be bent by applying a pressing force. When a pressing force is applied to the lever portion 33 a of the starting lever 33, the starting lever 33 rotates and the pressing force is transmitted to the raising / lowering rod 34. When a pressing force is applied to the raising / lowering rod 34, the thin portion 34a bends without being able to withstand this pressing force. When the thin portion 34a is bent in this manner, the raising / lowering rod 34 rotates with respect to the lid 31 around the thin portion 34a.

  By the way, although the siphon tube 70 of the present embodiment is formed using a light-transmitting ABS resin, it is not limited to this material. For example, even if a siphon tube formed using other resin (specifically, vinyl chloride, polypropylene, polyethylene, etc.) is used as long as the visible light transmittance is 5% to 95%, the present embodiment The same effect as the form can be achieved. In addition, materials other than a single resin, for example, a glass fiber-containing resin can also be applied to the present embodiment. In addition, it is further preferable that the visible light transmittance of the siphon tube made of each material other than the above-described resin alone is more preferably 5% or more and 85% or less, as in the present embodiment.

  Next, a method for manufacturing the fire extinguisher 100 will be described. First, the fire extinguisher storage container 10 of the present embodiment can be manufactured by a known resin molding method such as stretch blow molding, melt molding, etc. Among them, there is no seam except for the opening 13 and the molded state. Is preferable, and stretch blow molding is preferred in that a container having an appropriate thickness can be obtained.

  In addition, the fire extinguisher storage container 10 of this embodiment is formed of polyethylene naphthalate (PEN) containing perinone-based red as a pigment. Specifically, the fire extinguisher storage container 10 of the present embodiment was formed of polyethylene naphthalate (PEN) mixed with a master batch (a mixture of pigment and PEN). In the present embodiment, the master batch was formed by mixing 1.3 parts of perinone-based red with respect to 100 parts of polyethylene naphthalate (PEN). Moreover, the above-mentioned masterbatch was mixed in the ratio of 10% with respect to the polyethylene naphthalate (PEN).

  As a modification of the present embodiment, a fire extinguisher storage container having the same configuration except that the pigment contained in the fire extinguisher storage container 10 is cyanine blue instead of perinone red was also molded. In addition, the fire extinguisher storage container of this modification is formed of polyethylene naphthalate (PEN) containing cyanine blue as a pigment. Specifically, the fire extinguisher storage container of this modification is formed of polyethylene naphthalate (PEN) mixed with a master batch (a mixture of pigment and PEN). In this embodiment, the master batch is formed by mixing 0.16 part of cyanine blue with 100 parts of polyethylene naphthalate (PEN). Moreover, the above-mentioned master batch is mixed with polyethylene naphthalate (PEN) at a ratio of 5%.

  In this embodiment, after the extinguishing agent storage container 10 is formed, the extinguishing agent storage container 10 is formed by performing a fitting process in which the bottom 94 is inserted into the recess of the support base 50 provided with the adhesive. And the support 50 are bonded together by an adhesive (for example, a moisture curable adhesive).

  After the insertion step, as described above, the step of connecting the lid 31 and the hose 20 directly or indirectly with the extinguishing agent storage container 10 containing the extinguishing agent 60 is performed.

  By the way, the fire extinguisher 100 of this embodiment does not ask | require a pressurization type or a pressure accumulation type. For example, if the fire extinguisher 100 is a pressurized fire extinguisher, when the lid 31 is attached to the fire extinguisher storage container 10, a pressurizing cylinder (not shown) is stored in the fire extinguisher storage container 10 together with the fire extinguisher 60. On the other hand, if the fire extinguisher 100 is a pressure-accumulating fire extinguisher, after the above insertion process, the lid 31 is attached to the fire extinguisher storage container 10 containing the fire extinguisher 60, and then gas (for example, 0.9 MPa) Is introduced into the fire extinguisher storage container 10 through the lid 31.

  In particular, when a pressure-accumulating fire extinguisher is manufactured, it is not efficient to enclose a gas in the extinguishing agent storage container 10 before inserting the extinguishing agent storage container 10 into the recess of the support base 50. Therefore, it is not preferable. Therefore, as described above, after the insertion step, in other words, it is preferable to perform a step of enclosing gas in a state where the extinguishing agent storage container 10 is erected.

The material of the support 50 of the present embodiment, in order to obtain impact resistance and strength have high, polyethylene naphthalate, polyethylene terephthalate, acrylonitrile-butadiene-styrene copolymer synthetic resin, polyolefin, and polyphenylene sulfide, polystyrene, And at least one kind of resin selected from the group of polycarbonates. However, the material of the support base 50 of this embodiment is not limited to resin. Even if the support base 50 is made of metal (for example, aluminum or SUS304), it is possible to realize adhesion with the resin fire extinguisher storage container 10.

<Second Embodiment>
By the way, in 1st Embodiment, although the polyethylene naphthalate (PEN) containing a pigment was employ | adopted as a material of the fire extinguisher storage container 10, resin which does not contain a pigment was employ | adopted as a material of a fire extinguisher storage container. Even in this case, part of the effect of the first embodiment can be achieved. In addition, the fire extinguisher 200 of this embodiment and its manufacturing method are the fire extinguisher 100 of 1st Embodiment except the point to which the fire extinguisher storage container 10 of 1st Embodiment was changed into the fire extinguisher storage container 210. FIG. And the manufacturing method thereof. Therefore, the description which overlaps with 1st Embodiment may be abbreviate | omitted.

  For example, when a fire extinguisher storage container made of polyethylene naphthalate (PEN) containing no pigment is employed, the visible light transmittance reaches up to about 95%. As a result, when the fire extinguisher 200 including the fire extinguisher storage container 210 having a higher visible light transmittance than that of the first embodiment is employed, the siphon tube 70 accommodated therein is more visible than the first embodiment. Easy situation. However, the visible light transmittance of the siphon tube 70 of the present embodiment is not less than 5% and not more than 95%, as in the first embodiment. Therefore, even if the siphon tube 70 is inclined with respect to the ridgeline of the trunk portion of the fire extinguishing agent storage container 210 for some reason, it becomes inconspicuous when viewed from the outside. As a result, it is possible to prevent anxiety of the user of the fire extinguisher 200 from being excessively generated, and to prevent the initial fire extinguishing due to the appearance.

  Moreover, the difference between the visible light transmittance of the siphon tube 70 and the visible light transmittance of the extinguishing agent storage container 10 is not particularly limited. However, when the extinguishing agent storage container 10 has a lower visible light transmittance than the siphon tube 70, the visible light transmittance of the siphon tube 70 is smaller than that of the extinguishing agent storage container 10. It is preferable to mold so that the difference falls within the range of 90% or less. On the other hand, when the siphon tube 70 has a lower visible light transmittance than the fire extinguisher storage container 10, the visible light transmittance of the siphon tube 70 is compared with the visible light transmittance of the fire extinguisher storage container 10. It is preferable to mold so that the difference falls within the range of 30% or less. By setting the above-mentioned range, it is possible to more significantly reduce the anxiety of the user or the like. When the visible light transmittance of the siphon tube 70 is lower than that of the fire extinguisher storage container 10, the difference between the visible light transmittance of the siphon tube 70 and the visible light transmittance of the fire extinguisher storage container 10 is 20%. If the following, the above-described effects are further improved. From the viewpoint that it is possible to more significantly reduce the anxiety of the user or the like, even if any visible light transmittance is relatively low, the most preferable difference is 10% or less. .

It is stored. The siphon tube 270 of the present embodiment is formed using a resin that contains perinone red as a pigment and does not substantially transmit light (for example, vinyl chloride or polypropylene that does not transmit light). Therefore, the hue of the reflected light of the siphon tube 270 of the present embodiment is similar to the hue of the reflected light of the fire extinguisher storage container 10. As a result, even if the siphon tube 270 is inclined with respect to the ridgeline of the trunk portion of the fire extinguishing agent storage container 10 for some reason, it becomes inconspicuous when viewed from the outside. As a result, it is possible to remarkably reduce the anxiety of the user of the fire extinguisher 300 and to prevent the initial fire extinguishing due to the appearance.

  In the present embodiment, the fire extinguisher storage container 10 formed using polyethylene naphthalate (PEN) containing perinone red as a pigment, and a resin containing perinone red as a pigment (for example, has no translucency). Although the combination with the siphon tube 270 formed using vinyl chloride or polypropylene), the present embodiment is not limited to this combination. For example, even if each of the aforementioned base materials contains different pigments, if the color of the reflected light of the siphon tube is similar to the hue of the reflected light of the extinguishing agent storage container, The effects of the embodiment can be achieved.

<Modification (1) of Third Embodiment>
The fire extinguisher 400 and its manufacturing method of this embodiment are the same as the fire extinguisher 100 and its manufacturing method of the first embodiment, except that the siphon tube 70 of the first embodiment is changed to a siphon tube 370. is there. Therefore, the description which overlaps with 1st Embodiment may be abbreviate | omitted.

  In this embodiment, a siphon tube 370 is formed in a fire extinguisher storage container 10 that is molded using polyethylene naphthalate (PEN) containing perinone red as a pigment and has a visible light transmittance of 5% to 85%. It is stored. The siphon tube 370 of this embodiment is formed using aluminum instead of resin, and has substantially no translucency. However, the outer surface of the siphon tube 370 of the present embodiment is colored with a color material (for example, a pigment or dye such as anthraquinone yellow, anthraquinone red, polyazo red, or phthalocyanine blue). As a result, the hue of the reflected light from the siphon tube 370 is similar to the hue of the reflected light from the fire extinguisher storage container 10. As a result, even if the siphon tube 370 is inclined with respect to the ridgeline of the trunk portion of the extinguishing agent storage container 10 for some reason, it becomes inconspicuous when viewed from the outside. As a result, it is possible to significantly reduce the anxiety of the user of the fire extinguisher 400, and to prevent the initial fire extinguishing due to the appearance.

<Modification (3) of the third embodiment>
In the fire extinguisher 500 and the manufacturing method thereof according to the present embodiment, the fire extinguisher storage container 10 according to the first embodiment is changed to the fire extinguisher storage container 210 according to the second embodiment, and the siphon tube according to the first embodiment. Except for the point that 70 is changed to the siphon tube 470, the fire extinguisher 100 and the manufacturing method thereof according to the first embodiment are the same. Therefore, the description which overlaps with 1st Embodiment may be abbreviate | omitted.

  In this embodiment, a siphon tube 470 is housed in a fire extinguisher storage container 210 that is molded using polyethylene naphthalate (PEN) that does not contain a pigment and has a visible light transmittance of 5% to 95%. . The siphon tube 470 of the present embodiment is molded using a resin that does not contain a pigment (for example, a light-transmitting ABS resin), and has a visible light transmittance of 5% to 95%. In addition, the hue of the reflected light from the siphon tube 470 is shaped to be similar to the hue of the reflected light from the fire extinguisher storage container 210. As a result, even if the siphon tube 470 is inclined with respect to the ridgeline of the trunk portion of the extinguishing agent storage container 10 for some reason, it becomes inconspicuous when viewed from the outside. As a result, it is possible to remarkably reduce the anxiety of the user of the fire extinguisher 500 and the like, and to prevent the initial fire extinguishing due to the appearance.

  By the way, the difference between the visible light transmittance of the siphon tube 470 and the visible light transmittance of the fire extinguisher storage container 210 is not particularly limited. However, when the extinguishing agent storage container 210 has a lower visible light transmittance than the siphon tube 470, the visible light transmittance of the siphon tube 470 is less than that of the extinguishing agent storage container 210. It is preferable to mold so that the difference falls within the range of 90% or less. On the other hand, when the visible light transmittance of the siphon tube 470 is lower than that of the fire extinguisher storage container 210, the visible light transmittance of the siphon tube 470 is compared with the visible light transmittance of the fire extinguisher storage container 210. It is preferable to mold so that the difference falls within the range of 30% or less. By setting the above-mentioned range, it is possible to more significantly reduce the anxiety of the user or the like. When the visible light transmittance of the siphon tube 470 is lower than that of the fire extinguisher storage container 210, the difference between the visible light transmittance of the siphon tube 470 and the visible light transmittance of the fire extinguisher storage container 210 is 20%. If the following, the above-described effects are further improved. From the viewpoint that it is possible to more significantly reduce the anxiety of the user or the like, even if any visible light transmittance is relatively low, the most preferable difference is 10% or less. .

  As described above, the fire extinguisher 500 can be used by appropriately adjusting the hue of the reflected light even when the resin as the base material of the fire extinguisher storage container 210 and the siphon tube 470 does not contain a pigment. It is possible to remarkably reduce the anxiety of the person and the like, and to prevent hindering initial fire extinguishing due to the appearance. In addition, by appropriately adjusting the visible light transmittance of the fire extinguishing agent storage container 210 and the siphon tube 470, the above-described effects can be achieved and the respective effects can be achieved synergistically.

  In each of the above-described embodiments, for example, when the extinguishing agent is a light red powder extinguisher, if a part of the extinguishing agent is used during extinguishing, it is left as it is until it is collected. May end up. In such a case, if the effects of the above-described embodiments are not exhibited, the fire extinguisher storage container has visible light permeability, and thus the colored powder fire extinguisher remains in the siphon tube. Thus, the presence of the siphon tube can be visually recognized from the outside in a situation where the appearance is impaired. Similarly, even when a liquid material fire extinguisher is used, for example, when the location of the fire extinguisher is a place where the temperature is very cold, the difference in the degree of expansion of the gas in the fire extinguisher storage container due to heat As a result, the height of the liquid inside and outside the siphon tube may be different, resulting in a situation where the presence of the siphon tube can be visually recognized from the outside in a situation where the aesthetic appearance is impaired. Therefore, in the field of a fire extinguisher including a fire extinguisher storage container having visible light permeability, the effects of the above-described embodiments are exerted to make it difficult for a situation that impairs aesthetics as described above to occur. It should be noted.

<Other embodiments>
By the way, in each above-mentioned embodiment, although the pigment contained in resin which forms a fire extinguisher storage container was perinone red or cyanine blue, the employ | adopted pigment is not limited to them. For example, even if anthraquinone red or titanium oxide (TiO ₂ ) is employed instead of the above-described pigment, the same effects as those of the above-described embodiments can be achieved.

  In the third embodiment described above, the siphon tube 270 is formed using a resin that contains a pigment and has substantially no translucency. Instead, the siphon tube 270 contains a pigment, and Even if a siphon tube molded using a resin having translucency is employed, if the hue of the reflected light of the siphon tube is similar to the hue of the reflected light of the extinguishing agent storage container 10, the third embodiment The effect similar to the fire extinguisher 300 of a form is show | played. In particular, such a fire extinguisher is also a preferred embodiment because it is more difficult to see the siphon tube having translucency from the outside.

Further, when the siphon tube is molded using a resin, the reflected light of the siphon tube may be colored by the resin itself even if the pigment is not included. In such a case, the siphon tube may or may not have translucency. In any case, by the hue of the reflected light of the siphon tube is adjusted so that the hue and the same color of the reflected light of the fire extinguishing agent storage vessel, the same effects as the embodiments described above Can be played. The same applies to the fire extinguisher storage container that the reflected light can be colored by the resin itself even if no pigment is contained.

  In addition, when the siphon tube is molded using a resin, examples of other materials that can be used include nylon 6,6, polyolefins such as polyethylene and polypropylene, polycarbonate, epoxy resin, and silicon resin.

  Moreover, in each above-mentioned embodiment, although polyethylene naphthalate (PEN) is employ | adopted as resin which comprises a fire extinguisher storage container, resin employ | adopted is not limited to this. For example, a polyester resin obtained by polycondensation using mainly naphthalenedicarboxylic acid or terephthalic acid as a dicarboxylic acid component and mainly ethylene glycol or butanediol as a diol component, or a material mainly containing these polyester resins is a fire extinguisher. Even if it is adopted as a material for the 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.

  Examples of other materials that can be used for the fire extinguisher storage container include polyolefins such as polyethylene and polypropylene, polyphenylene sulfide, polystyrene, and polycarbonate. However, among all the above materials, it is preferable from the viewpoint of strength to employ polyethylene terephthalate (PET) or polyethylene naphthalate (PEN). From the viewpoint of gas barrier properties, polyethylene naphthalate (PEN) is most preferably employed alone. That is, by adopting polyethylene naphthalate (PEN), a fire extinguisher storage container having high strength and excellent gas barrier properties can be obtained with higher accuracy.

  In addition, a known coating film or a film containing a known pigment may be disposed on the outer peripheral surface of the extinguishing agent storage container of the fire extinguisher of each of the above-described embodiments. For example, the name of the manufacturer of the fire extinguisher and the film with the description and decoration for indicating the performance of the fire extinguisher are widely used, but their use does not hinder the effects of the above-described embodiments. .

  Furthermore, if the additive does not impair the effects of the above-described embodiments, the resin constituting the fire extinguisher storage container is a light stabilizer, an ultraviolet absorber, or for preventing discoloration and improving weather resistance. Known additives such as anti-aging agents can be appropriately blended.

  The disclosure of each of the above-described embodiments is described for explaining the embodiments, and is not described for limiting the present invention.
