Description

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

  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 reduced as much as possible so that even a low pressure resistance, which was a weak point of a resin-made fire extinguisher storage container, is maintained (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). No specific proposal has been disclosed yet for individual technical issues, particularly for improving the mass production technology of resin-made extinguishing agent storage containers.

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 extinguishant storage containers, which 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.

  By the way, the fire extinguisher having a resin-made fire extinguishing agent storage container having higher strength and the like proposed by the applicant of the present application has a curved surface at the bottom of the fire extinguishing agent storage container. A container alone cannot maintain a standing state like a general fire extinguisher. Therefore, the applicant of the present application has proposed a support base having a recess into which the bottom portion is fitted so that such a fire extinguisher storage container can be kept upright (as an example, described in Patent Document 4 above). Support stand).

  However, in the mass production stage, it is required to produce a large number of fire extinguishers in a short time. From the viewpoint of mass production, it takes a long time to bond the fire extinguisher storage container and the support base. Unacceptable. On the other hand, since the required level for the strength of the fire extinguisher is high, according to the intensive research and analysis by the inventors of the present application, the contents are molded using a resin with high chemical resistance due to the special nature of the fire extinguishing agent. In order to develop a high level of adhesive strength for a fire extinguisher storage container, considerable time (for example, several hours or more than half a day) may be required as long as adhesives currently available in the industry are used. all right.

  The present invention solves the above-mentioned technical problems, and even if it has a resin-made fire extinguishing agent storage container, it finally exhibits a higher degree of adhesive strength with the support base, and each step in mass production. This greatly contributes to the realization of mass production technology for fire extinguishers that can be applied without difficulty.

  For example, regardless of pressure accumulation type or pressure type, work to introduce a fire extinguisher into a fire extinguisher storage container having a curved bottom before the process of inserting the fire extinguisher storage container into the support base, or opening of the fire extinguisher storage container It is not preferable from the viewpoint of work efficiency and work accuracy to perform the work of installing the valve case that closes the part, because the work is performed while the fire extinguishing agent storage container is laid down. In particular, in the case of a pressure-accumulating fire extinguisher, it is not realistic from the viewpoint of workability and safety to introduce gas into the fire extinguisher storage container while the fire extinguisher storage container is laid down. Therefore, from the viewpoint of mass production, each of the above-described processes or operations may be performed after the fire-extinguishing agent storage container is inserted into the support base, in other words, with the fire-extinguishing agent storage device standing. Desired. Therefore, if an excessively long time is required for the bonding process between the support base and the extinguishing agent storage container, the production capacity will be greatly hindered.

  Therefore, the inventors of the present application are able to withstand the mass production of the present adhesive that is useful as the final adhesive strength but is difficult to adopt in the mass production stage of a fire extinguisher equipped with a fire extinguisher storage container. We conducted an intensive study on how to use it. As a result of research and trial and error, the inventors of the present application have developed a new adhesive strength that can solve the above-described problems related to a fire extinguisher storage container having a curved bottom, apart from the adhesive strength required as a final product. The present inventors have found a method for manufacturing a fire extinguisher that does not hinder mass production. The present invention was created based on such a viewpoint.

  The manufacturing method of one fire extinguisher of this invention includes the following two processes. One step is to form at least part of the bottom of the substantially cylindrical body of the fire extinguisher storage container and / or the outer surface of the bottom of the fire extinguisher storage container, which is seamlessly molded using a resin and has a curved bottom. A first adhesive having a short time until adhesiveness develops on either or both of at least a part of the surface of the concave portion of the support base of the above-described extinguishing agent storage container having a concave portion for insertion; and This is a step of providing a second adhesive that is long in the time until the adhesiveness is developed and that adheres stronger than the first adhesive at different positions. Another process is a fitting process in which the bottom part is fitted into the concave part.

  According to this manufacturing method, between the fire extinguishing agent storage container and the support base having the recess into which the bottom portion is fitted, the first adhesive having a short time until the adhesiveness is developed, and the adhesiveness are developed. It takes a long time until the second adhesive that adheres stronger than the first adhesive is located at different positions. Therefore, the initial adhesive strength in the manufacturing process of the fire extinguisher is manifested in a short time due to the presence of the first adhesive, and then the fire extinguisher storage container and the bottom thereof are fitted over time due to the presence of the second adhesive. Strong adhesion with the supporting base having the recessed portion is realized. As a result, in the manufacturing process, for example, an operator or a manufacturing robot can perform a process after the insertion process (for example, a process for introducing a fire extinguisher, a process for closing a fire extinguisher storage container with a lid (also called a valve case), or a gas Since the introduction and encapsulation process) can be started quickly, work efficiency is greatly improved.

  In the above-described invention, at least a part of the extinguisher storage container below the trunk and / or on the outer surface of the bottom of the extinguisher storage container, and a support for the extinguishant storage container described above having a recess for fitting the bottom. There is no particular limitation on the order in which the above-mentioned adhesives are provided on either one or both of at least a part of the concave surface. Therefore, there is no reason that the first adhesive having a shorter time until the adhesiveness is developed must be provided after the second adhesive. Specifically, for example, when a double-sided tape is employed as the first adhesive, for example, those skilled in the art will understand that the order relationship with the second adhesive is not limited.

  Moreover, one fire extinguisher of this invention is shape | molded seamlessly using resin. In addition, this fire extinguisher has at least a part below the substantially cylindrical trunk of the extinguishant storage container having a curved bottom and / or on the outer surface of the bottom, and a recess into which the bottom is fitted. The first adhesive having a short time until the adhesiveness develops and the time until the adhesiveness develops between at least a part of the support surface of the extinguishing agent storage container and at least a part of the surface of the concave portion. The second adhesive that adheres more firmly than the first adhesive is provided at different positions.

  According to this fire extinguisher, the first adhesive having a short time until the adhesiveness is developed and the adhesiveness are developed between the fire extinguisher storage container and the support base having the recess into which the bottom portion is inserted. It takes a long time until the second adhesive that adheres stronger than the first adhesive is located at different positions. Therefore, the initial adhesive strength in the manufacturing process of the fire extinguisher is manifested in a short time due to the presence of the first adhesive, and then the fire extinguisher storage container and the bottom thereof are fitted over time due to the presence of the second adhesive. Strong adhesion with the supporting base having the recessed portion is realized. As a result, in the manufacturing process, for example, an operator or a manufacturing robot promptly starts a process after the fitting process (for example, a fire extinguishing agent storing process, a valve case installing process, or a gas introducing and sealing process). As a result, the work efficiency is greatly improved.

  By the way, in the present application, “adhesiveness” means that after the bottom of the extinguishing agent storage container is fitted into the recess of the support base, at least the adhesive and the extinguishing agent storage container can be prevented from rotating or sliding. Refers to performance.

  According to one manufacturing method of the present invention or one fire extinguisher of the present invention, the time until adhesiveness is developed between the fire extinguisher storage container and the support base having a recess into which the bottom portion is fitted. The short first adhesive and the second adhesive that adheres stronger than the first adhesive and has a long time until the adhesiveness is developed are provided at different positions. Therefore, the initial adhesive strength in the manufacturing process of the fire extinguisher is manifested in a short time due to the presence of the first adhesive, and then the fire extinguisher storage container and the bottom thereof are fitted over time due to the presence of the second adhesive. Strong adhesion with the supporting base having the recessed portion is realized. As a result, in the manufacturing process, for example, an operator or a manufacturing robot can quickly start a process after the fitting process (for example, a valve case installation process or a gas introduction and encapsulation process). Efficiency is greatly improved.

<First Embodiment>
FIG. 1 is a side view of a fire extinguisher 100 in the present embodiment. It is. Moreover, FIG. 2A is a side view of the fire extinguisher storage container 10 which is a part of the fire extinguisher 100 in the present embodiment, and FIG. 2B is a cross-sectional view of the fire extinguisher storage container 10. Moreover, FIG. 3A is a perspective view of the support base 50 which shows one process of the manufacturing process of the fire extinguisher 100 in this embodiment, and FIG. 3B is XX sectional drawing of FIG. 3A. 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 and the support base 50 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.

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. .

  Here, 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 FIGS. 3A and 3B, the support base 50 of the present embodiment includes a receiving part 51 having a recess 54 and a base part 53 that supports the receiving part 51. The fire extinguisher storage container 10 of the present embodiment is made of a resin (polyethylene naphthalate (PEN)) containing a pigment and has a curved surface at the bottom 94, as will be described later. 50 is supported so that it can stand upright.

  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.

  In addition, it is preferable that the total light transmittance of the fire extinguisher storage container 10 of this embodiment is 5% or more and 75% or less. When the total light transmittance of the fire extinguishing agent storage container 10 of the present embodiment exceeds 75%, the extinguishant adhering to the wall surface of the fire extinguishing agent looks like dirt on the fire extinguisher, so that the fire extinguisher 100 is installed. This will damage the beauty of the surrounding area. On the other hand, if the total light transmittance is less than 5%, it becomes difficult to check the remaining amount of the extinguishing agent, so that the practicality is inferior. Therefore, maintaining moderate transparency in the above-described range harmonizes practicality and aesthetic appearance. In addition, the more preferable extinguishing agent storage container has a total light transmittance of 20% to 70%. Within this range, it is possible to further harmonize with the surrounding aesthetics.

  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 made of a cross-linked polyethylene resin and includes a siphon tube fixing portion 31d for fixing the tip of the siphon tube 70 and a sponge-like grip portion 22 having a large outer diameter so as to be easily held by humans. A hose fixing portion 31c for fixing the tip of the flexible hose 20 is provided. In addition, in a part of the flow path 31e from the siphon tube fixing portion 31d to the hose fixing portion 31c, a metal (for allowing the extinguishing agent 60 scheduled to be stored in the extinguishing agent storage container 10 to flow to the hose 20 ( Specifically, a valve rod (valve) 32 made of SUS304 is arranged to be 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 a safety plug 35, which will be described later, is inserted in the future, and a second opening 33e through which the engagement protrusion 35a and the protrusion 35b of the safety plug 35 pass. ing. 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.

  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 0.1 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 20%.

  In the present embodiment, after the extinguishing agent storage container 10 is formed, the extinguishing agent storage container is formed by performing a fitting process in which the bottom portion 94 is fitted into the recess 54 of the support base 50 provided with the adhesive. 10 and the support 50 are bonded together. More specifically, as shown in FIGS. 3A and 3B, on the inner wall surface 52 of the recess 54 of the support base 50, a commercially available hot melt adhesive that is the first adhesive 82 and the second adhesive are circumferentially formed. The moisture curable adhesive that is the agent 84 is provided at different positions.

  Here, the first adhesive 82 has a short time from when the first adhesive is provided until the adhesiveness is developed (for example, the expression time is 30 seconds or less). In addition, the second adhesive 84 adheres more firmly than the first adhesive 82, but the time from when the second adhesive is provided until the adhesiveness is developed (for example, the expression time is 60). Min or more). Thus, by using two kinds of adhesives having different properties, the initial adhesive strength required for the manufacturing process of the fire extinguisher 100 is ensured in a short time by the presence of the first adhesive 82 after the insertion process, Thereafter, due to the presence of the second adhesive 84, a strong adhesion between the fire extinguishing agent storage container 10 and the support base 50 is realized over time.

  It should be noted that, after 48 hours have passed since the above insertion process, the applicant of the present application performs a test of dropping three times from a height of 1.5 m in order to examine the adhesive strength between the extinguishing agent storage container 10 and the support base 50. As a result, it was confirmed that the adhesive state between the extinguishing agent storage container 10 and the support base 50 was maintained. In this embodiment, the time from when the first adhesive 82 is provided until the adhesiveness is developed is 30 seconds or less. However, if the time is 5 minutes or less, the first adhesive 82 is used. Can serve as a The second adhesive 84 has an adhesive property of about 15 minutes, and there is an adhesive having a higher adhesive strength than the first adhesive 82 (for example, an epoxy-based two-component liquid). adhesive). Therefore, it is also a preferable aspect to employ such a second adhesive 84.

  In the present embodiment, the second adhesive 84 is positioned in the upper layer than the first adhesive 82. As a result, the second adhesive 84 for exerting the final bonding strength is covered with the first adhesive 82 that hangs down due to gravity depending on the viscosity, for example, during or before the insertion process. There is no possibility.

  By the way, in each above-mentioned embodiment, although the bottom part 94 of the fire extinguisher storage container 10 is inserted and adhered in the recessed part 54 of the support stand 50, if the depth of the recessed part 54 is deeper, the fire extinguisher storage container 10 In addition to the bottom portion 94, a lower portion of the trunk portion 93 can be fitted into the recess 54. Therefore, as one aspect different from the present embodiment, in the region where the first adhesive 82 and the second adhesive 84 can be interposed between the support base 50 and the extinguishing agent storage container 10, the extinguishing agent storage container The lower part of 10 trunk parts 93 is included. In other words, not only the bottom 94 of the extinguishing agent storage container 10 but also the lower part of the trunk 93 is included in the place where the inner wall 52 of the support 50 is bonded.

  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 manufacturing a pressure-accumulating fire extinguisher, it is efficient to enclose a gas in the extinguishing agent storage container 10 before inserting the extinguishing agent storage container 10 into the recess 54 of the support base 50. It is not preferable because it is bad. 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.

  In addition, the material of the support base 50 of the present embodiment is that the support base 50 is made of polyethylene naphthalate, polyethylene terephthalate, acrylonitrile / butadiene / styrene copolymer synthetic resin, polyolefin, and polyphenylene sulfate in order to obtain high impact resistance and strength. It is formed of at least one resin selected from the group consisting of fido, polystyrene, and polycarbonate. 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. Therefore, as in this embodiment, the first adhesive 82 has a short time until the adhesiveness develops, and the first adhesive 82 has a long time until the adhesiveness develops, but adheres stronger than the first adhesive. The aspect that exhibits both the goodness of the two adhesives 84 can be applied even if the support base 50 is a metal. That is, regardless of the material of the support base 50, at least one part on the lower surface of the trunk portion 93 of the extinguishing agent storage container 10 and / or on the outer surface of the bottom portion 94 and at least one on the inner wall surface 52 of the concave portion 54 of the support base 50.

<Other embodiments>
By the way, in each above-mentioned embodiment, before an insertion process is performed, the 1st adhesive agent 82 and the 2nd adhesive agent 84 are below the trunk | drum 93 of the fire extinguishing agent storage container 10, and / or on the outer surface of the bottom part 94. The timing of the step of providing the first adhesive 82 and the second adhesive 84 is provided on at least one of the at least a part and at least a part of the inner wall 52 of the recess 54 of the support base 50. It is also possible to adopt a case where they are different.

  For example, FIG. 11A and FIG. 11B are partial cross-sectional views illustrating a process of manufacturing a fire extinguisher in an aspect. As shown in FIGS. 11A and 11B, first, after the first adhesive 82 is provided on the inner wall surface 52 of the recess 54 of the support base 50, the extinguishing agent storage container 10 is fitted into the recess 54 (FIG. 11A). . At this time, the outer diameter of the extinguishing agent storage container 10 and the support base are so formed that at least a part of a slight gap is formed between the outer peripheral shape of the extinguishing agent storage container 10 and the inner wall surface 52 of the recess 54 of the support base 50. The inner diameter of the 50 recesses 54 is set. Then, after each process including the introduction process of the extinguishing agent 60 and the closing process of the extinguishing agent storage container 10 by the lid 31 is performed as in the above-described embodiments, the second process is performed using a known injector or the like. Adhesive 84 is introduced into the aforementioned gap (FIG. 11B). As a result, due to the presence of the first adhesive 82, the initial adhesive strength required when the subsequent steps described above for the fire extinguisher storage container 10 are performed quickly is ensured in a short time. And in the case of a pressure accumulation type fire extinguisher, after that, the process in which gas (for example, about 0.9 MPa) is introduced in the fire extinguisher storage container 10 is performed.

  In addition, due to the presence of the second adhesive 84, a strong adhesion between the fire extinguisher storage container 10 and the support base 50 is realized over time, so that a higher impact resistance as a final fire extinguisher is achieved. Or strength can be obtained. In addition, the process which provides the 1st adhesive agent 82 on the outer surface of the bottom part 94 of the fire extinguisher storage container 10 is employ | adopted independently or together with arrangement | positioning of the adhesive agent to the support stand 50 instead of the process shown in FIG. 11A. This is another preferred embodiment.

  As above-mentioned, the insertion process of the fire extinguishing agent storage container 10 does not necessarily need to be performed after the 1st adhesive agent 82 and the 2nd adhesive agent 84 are provided. Furthermore, it is another preferable that at least a part of the slight gap is formed between the outer peripheral shape of the extinguishing agent storage container 10 and the inner wall surface 52 of the concave portion 54 of the support base 50, which can also be adopted in each of the above-described embodiments. It is one mode.

  In addition, in the insertion process of the extinguishing agent storage container 10, the manufacturing method of the fire extinguisher which has the process of forming at least one part of a slight clearance gap is suitable especially when manufacturing a pressure accumulation type fire extinguisher. This is because, in the case of a pressure-accumulating fire extinguisher, a process of introducing gas (for example, about 0.9 MPa) is performed after the fitting process, so that the fire extinguisher storage container 10 expands. Therefore, in advance of the gas introduction and sealing step, at least a part of the slight gap is formed between the outer peripheral shape of the extinguishing agent storage container 10 and the inner wall surface 52 of the recess 54 of the support base 50 in advance. By designing, the extinguishing agent storage container 10 expands so as to narrow or fill the gap, so that it is not necessary to apply an excessive load to the support base 50. In addition, as shown in FIG. 11B, the second adhesive 84 is introduced and provided after the insertion process of the fire extinguisher storage container 10, so that the expansion of the fire extinguisher storage container 10 is caused to extinguish through the second adhesive 84. The adhesiveness between the agent storage container 10 and the support base 50 is further enhanced.

Moreover, when the 1st adhesive agent 82 is a double-sided tape, it means when the protective sheet of the slow-release side is peeled among the protective sheets which protect the double-sided tape.

  Similarly, in each above-mentioned embodiment, although the 2nd adhesive agent 84 was a moisture hardening type adhesive agent, it is not limited to this. For example, if it is an epoxy type 2 liquid adhesive or a urethane type adhesive, at least one part of the effect of each above-mentioned embodiment may be show | played.

Moreover, 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.

  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 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. . Therefore, in the present application, “below the trunk of the extinguishing agent storage container and / or on the outer surface of the bottom” includes not only the outer surface of the trunk and / or the bottom, but also the outer surface of the trunk and / or the bottom.
