Description

[Technical field]

[0001] The present invention relates to a fire extinguishing and fire resistant bag. [Background technology]

[0002] In recent years, electronic devices (such as smartphones, tablets, and laptops) are equipped with built-in batteries, typically lithium-ion batteries. Due to aging or poor quality, these batteries can become abnormally hot, which can lead to smoke or fire. Summary of the Invention [Problem to be solved by the invention]

[0003] In particular, when a battery built into an electronic device emits smoke or catches fire inside an aircraft such as a passenger plane, this can lead to a fire or explosion. If an electronic device containing a battery that is abnormally hot or emitting smoke or fire is left in this state, there is a risk of passengers or crew being burned or the aircraft being damaged. For this reason, there is a demand for a fire-extinguishing and fire-resistant bag for use inside an aircraft that can easily isolate and block heat from electronic devices that are abnormally hot or emitting smoke or fire (hereinafter referred to as "high-heat body"), and that can reduce the intensity of the fire and prevent the subsequent spread and spread of the fire. [Means for solving the problem]

[0004] This problem is solved by a fire-extinguishing fire-resistant bag for use on aircraft, which comprises a first surface member and a second surface member formed of a fire-resistant material such that they face each other and have some of their peripheral edges joined, with the unjoined peripheral edges defining an opening and defining a hollow space inside, wherein the first surface member comprises an external bag body having a tab, and an internal resin film that can be folded in the middle and is formed to incorporate a fire-extinguishing sheet that can release a fire-extinguishing agent aerosol, the external bag body being capable of storing the internal resin film in the hollow space of the external bag body, and the tab of the first surface member being capable of being folded and fixed to the outer surface of the second surface member so as to close the opening. Effect of the Invention

[0005] This device has a simple structure and is easy to handle, allowing high-temperature objects to be safely isolated and heat to be blocked from the outside. [Brief description of the drawings]

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] (Configuration of Fire Extinguishing Fireproof Bag 1) With reference to Figs. 1A to 3B, a fire extinguishing and fireproof bag 1 used in an aircraft will be described as an embodiment of the present invention. Fig. 1A is a perspective view showing the structure of the fire extinguishing and fireproof bag 1 according to the embodiment with the opening of the fire extinguishing and fireproof bag 1 open.

Fig. 2B is a view showing an example of the disassembled state of the inner resin film 3 of the fire extinguishing and fireproof bag 1 according to the embodiment. Fig. 3A is a view showing a method of using the fire extinguishing and fireproof bag 1 according to the embodiment up to the stage (initial stage) where the opening of the outer bag body 2 is open. Fig. 3B is a view showing a method of using the fire extinguishing and fireproof bag 1 according to the embodiment up to the stage (final stage) where the opening of the outer bag body 2 is closed.

[0008] 1A and 1B, the fire extinguishing and fire-resistant bag 1 includes an outer bag body 2 and an inner resin film 3. Also, as shown in Fig. 2A, the outer bag body 2 includes a first surface member 21, a second surface member 22, and a tab 23. The first surface member 21 includes the tab 23.

[0009] The first surface member 21, the second surface member 22, and the tab 23 that constitute the outer bag body 2 are made of a fire-resistant material. Specifically, the fire-resistant material is a two-layer material in which an aluminum vapor deposition film is bonded to a blended woven fabric of aramid and carbon, and a nonwoven fabric of oxidized polyacrylonitrile fiber is sewn to the blended woven fabric side.

[0010] The first surface member 21 and the second surface member 22 are configured such that the inner surface 21a of the first surface member 21 and the inner surface 22a of the second surface member 22 face each other, and the peripheral edge 21b of the first surface member 21, which is a part of the peripheral edge of the first surface member 21 and the second surface member 22, and the peripheral edge 22b of the second surface member 22 are joined, and the non-joined peripheral edges define the opening 2a and define a hollow portion 2b inside. The first surface member 21, the second surface member 22, and the tab 23 can each be configured as three separate members. Alternatively, the first surface member 21 and the second surface member 22 may be an integral member connected to each other and the tab 23 may be a separate member, or the first surface member 21 and the tab 23 may be an integral member connected to each other and the second surface member 22 may be a separate member. Furthermore, the first surface member 21, the second surface member 22, and the tab 23 may all be connected to form an integral member. Here, an example in which the first surface member 21, the second surface member 22, and the tab 23 are all connected to form an integral member will be described.

[0011] When the first surface member 21, the second surface member 22, and the tab 23 are all connected to form a single integral member, the outer bag body 2 is composed of a single belt-shaped body 20 made of a fire-resistant material, and the belt-shaped body 20 is divided in the longitudinal direction L of the belt shape so that the second surface member 22, the first surface member 21, and the tab 23 are adjacent to each other and integral in this order.

[0012] The second surface member 22 is formed by folding the band-shaped body 20 located between the second surface member 22 and the first surface member 21 at a folding line 2c in the short direction W perpendicular to the longitudinal direction L of the band-shaped body 20 as shown by the arrow F1 in Fig. 2A, and sewing together the peripheral edge 21b in the longitudinal direction L of the band-shaped body 20 so that the inner surface 21a of the first surface member 21 and the inner surface 22a of the second surface member 22 face each other. As a result, a hollow portion 2b of the outer bag body 2 is defined between the inner surface 21a of the first surface member 21 and the inner surface 22a of the second surface member 22.

[0013] In a state where the band-shaped body 20 is folded at the folding line 2c, the length of the first surface member 21 in the longitudinal direction L of the band shape is longer than the length of the second surface member 22 in the longitudinal direction L of the band shape. The portion of the first surface member 21 that is longer than the length of the second surface member 22 in the longitudinal direction L of the band shape becomes a tab 23. The tab 23 can be folded at a folding line 2e in the short direction W perpendicular to the longitudinal direction L of the band-shaped body 20 located between the first surface member 21 and the tab 23. An edge 2d in the short direction W perpendicular to the longitudinal direction L of the band-shaped body 20 of the portion of the band-shaped body 20 corresponding to the second surface member 22, which is an edge on the opposite side to the folding line 2c, defines an opening 2a together with the folding line 2e in a state where the band-shaped body 20 is folded at the folding line 2c. The opening 2a is an opening that communicates with the hollow portion 2b of the outer bag body 2. The tab 23 is movable so as to bend at the fold line 2e as indicated by the arrow F2 in FIG. 3A to close or open the opening 2a, and can be folded and fixed to the outer surface of the second surface member 22 when the opening 2a is closed.

[0014] A first fastener member 24a of the first hook-and-loop fastener 24 is disposed on the inner surface of the tab 23 of the band-shaped body 20 made of a fire-resistant material so as to extend along the short-side direction W of the band. A second fastener member 24b of the first hook-and-loop fastener 24 is disposed on the outer surface (opposite the inner surface 22a) of the band-shaped body 20 at the position of the second surface member 22, on the side of the tab 23. The first hook-and-loop fastener 24 is typically a hook-and-loop fastener having a male member on one side and a female member on the other side, such as Velcro (registered trademark), in which the male member and the female member are engaged with each other to contact and fix the male member and the female member in a detachable manner. Either the first fastener member 24a or the second fastener member 24b of the first hook-and-loop fastener 24 can be a male member, and the other can be a female member. As a result, when the tab 23 is folded at the fold line 2e to close the opening 2a, the male and female members of the first hook-and-loop fastener 24 join together, i.e., the first fastener member 24a and the second fastener member 24b of the first hook-and-loop fastener 24 join together, making it possible to fold and fix the tab 23 to the outer surface of the second hook-and-loop member 22.

[0015] A first fastener member 25a and a second fastener member 25b of a second hook-and-loop fastener 25 are arranged along the periphery 21b on both sides of the first surface member 21 on the outer surface (opposite surface to the inner surface 21a of the first surface member 21) of the band-shaped body 20 made of a fire-resistant material. That is, the first fastener member 25a and the second fastener member 25b are arranged symmetrically with respect to a center line along the longitudinal direction L of the band shape of the band-shaped body 20, which passes through the midpoint of the lateral direction W of the band shape of the band-shaped body 20 made of a fire-resistant material (the center line of the width that is the lateral direction of the band shape).

[0016] The second hook-and-loop fastener 25 is also configured to have one male member and the other female member, similar to the first hook-and-loop fastener 24, and is a hook-and-loop fastener that can be detachably fixed in contact with the female member by engaging the male member with the female member. One of the first fastener member 25a and the second fastener member 25b of the second hook-and-loop fastener 25 is a male member, and the other is a female member. As a result, as shown in FIG. 3A, the outer bag body 2 can be folded in two and fixed by folding the outer bag body 2 along the center line 2CL along the longitudinal direction L of the band-shaped body 20 as shown by the arrow F3 in FIG. 3A, with the tab 23 folded and fixed to the outer surface of the second surface member 22, so that the outer surfaces at the position of the first surface member 21 (the surface opposite to the inner surface 21a of the first surface member 21) face each other.

[0017] That is, by joining and fixing the first fastener member 25a and the second fastener member 25b of the second hook-and-loop fastener 25, the outer bag body 2 is folded in two and fixed along the center line 2CL so that the outer surfaces of the first surface member 21 face each other along the center line 2CL with the tab 23 on the outside. The tab 23 is firmly fixed to the second surface member 22 by the first hook-and-loop fastener 24, and further, by folding the outer bag body 2 in two and fixing it along the center line 2CL by the second hook-and-loop fastener 25 with the tab 23 on the outside, a locking effect is created that prevents the tab 23 from coming off the second surface member 22.

[0018] The internal resin film 3 is an internal resin film that is formed to incorporate the fire extinguishing sheet 31 and can be folded at the center. The incorporated fire extinguishing sheet 31 is formed as a film that can release a predetermined fire extinguishing agent aerosol. For example, the fire extinguishing sheet 31 may contain at least one salt of an organic salt and an inorganic salt. Also, it may contain either a thermoplastic resin or a thermosetting resin as a binder. The internal resin film 3 is a flexible resin film, and its thickness is set so that it can be easily curved while having a restorability that allows it to be restored to its original sheet state. Examples of materials for the internal resin film 3 include polyolefin (LLDPE, PP, COP, CPP, etc.), polyester (PET, etc.), fluororesin (PTFE, ETFE, EFEP, PFA, FEP, PCTFE, etc.), PVC, PVA, acrylic resin, epoxy resin, polyamide, polyimide, etc.

[0019] The number of fire extinguishing sheets 31 built into the internal resin film 3 can be one or more. Hereinafter, an example in which there are two fire extinguishing sheets 31 will be described. When there are two fire extinguishing sheets 31, the fire extinguishing sheet 31 can be, for example, two fire extinguishing sheet members 31a and 31b, as shown in FIG. 2B. When there are two fire extinguishing sheets 31, the two fire extinguishing sheet members 31a and 31b are hermetically sandwiched between the resin film 32a and the resin film 32b. The internal resin film 3 can be folded in two at the center line 3CL between the fire extinguishing sheet member 31a and the fire extinguishing sheet member 31b in the center of the internal resin film 3.

[0020] The internal resin film 3 can be stored in the hollow portion 2b of the external bag 2. The size of the internal resin film 3 is smaller than the size of the inside dimension of the hollow portion 2b of the external bag 2, but it is preferable that the size of the internal resin film 3 exactly matches the size of the inside dimension of the hollow portion 2b of the external bag 2. That is, the size of the internal resin film 3 must be such that, when stored in the hollow portion 2b of the external bag 2, the tab 23 of the external bag 2 closes the opening 2a without any gaps and does not hinder folding and fixing to the outer surface of the second surface member 22. That is, the width W3 of the internal resin film 3 is smaller than the width W2 of the hollow portion 2b of the external bag 2, and the height H3 of the internal resin film 3 is smaller than the width H2 of the hollow portion 2b of the external bag 2. When the internal resin film 3 does not hold the high-heat body 4, it is stored in the hollow portion 2b of the external bag 2 without being folded along the center line 3CL. In this state, the external bag 2 can be folded along the center line 2CL and folded and fixed by the second hook-and-loop fastener 25.

[0021] (Use of the fire extinguishing fireproof bag 1) Next, a description will be given of a mode of use of the fire extinguishing and fireproof bag 1 with reference to Figures 1A, 1B, 3A and 3B. When the fire extinguishing and fireproof bag 1 is unused, the internal resin film 3 is stored in the hollow portion 2b inside the external bag body 2, as shown in Figure 1B. Even when the fire extinguishing and fireproof bag 1 is unused, it may be folded in half and fixed along the center line 2CL.

[0022] As shown in Fig. 1A, an internal resin film 3 is stored in a hollow portion 2b of an external bag 2. When a high-heat object 4 appears, the high-heat object 4 is stored in the hollow portion 2b of the external bag 2 into which the internal resin film 3 has been inserted, as shown in Fig. 3A. When the high-heat object 4 is sufficiently small relative to the size of the hollow portion 2b of the external bag 2, after storing the high-heat object 4 in the hollow portion 2b, the external bag 2 may be folded along a center line 2CL and stored in the hollow portion 2b of the external bag 2 so that the high-heat object 4 is biased to one side of the hollow portion 2b of the external bag 2.

[0023] After the high-heat body 4 is completely stored in the hollow portion 2b of the fire-extinguishing and fire-resistant bag, the tab 23 is folded at the folding line 2e as shown by the arrow F2 in FIG. 3B to close the opening 2a. Then, the first fastener member 24a of the tab 23, which is the first hook-and-loop fastener 24, and the second fastener member 24b of the second surface member 22 of the outer bag body 2 are joined to firmly fold and fix the tab 23 to the outer surface of the second surface member 22. In this state, the opening of the tab 23 is restricted and the tab 23 will no longer open, and the hollow portion 2b of the outer bag body 2 is isolated from the outside, blocking the inflow of air from the outside and preventing ignition and the spread of fire. In addition, the material of the outer bag body 2 can also prevent the temperature of the outer bag body 2 from rising. In addition, in the hollow portion 2b of the outer bag body 2, it is possible to prevent ignition of the high-heat body 4 due to the effect of the aerosol generated from the fire-extinguishing sheet 31, and if a fire has already started, a fire-extinguishing effect is expected. Furthermore, if necessary, the outer bag body 2 can be submerged in water to further prevent the fire from spreading to the outside.

[0024] Furthermore, when the high-heat object 4 is stored in the hollow portion 2b of the outer bag 2 so that the high-heat object 4 is biased to one side of the hollow portion 2b of the outer bag 2, the outer bag 2 can be folded in two so that the tab 23 is on the outside with respect to the center line 2CL of the outer bag 2 and the outer surfaces of the first surface member 21 face each other, as shown by the arrow F3 in FIG. 3B. Then, the first fastener member 25a and the second fastener member 25b of the second hook-and-loop fastener 25 on the first surface member 21 are joined to securely fold the outer bag 2 in two and fix it. When the first fastener member 25a and the second fastener member 25b of the second hook-and-loop fastener 25 are joined, the opening of the tab 23 is further completely restricted, and the opening of the tab 23 makes it impossible to open the opening 2a. In this state, the hollow portion 2b is divided into two, so that the aerosol generated from the fire-extinguishing sheet 31 easily fills the hollow portion 2b, and the fire-extinguishing effect is easily achieved. In addition, even when the fire-extinguishing fireproof bag 1 is not in use and no high-heat body 4 is stored inside, the size of the fire-extinguishing fireproof bag 1 can be reduced by connecting the first fastener member 25a and the second fastener member 25b of the second hook-and-loop fastener 25 on the first surface member 21, making it easier to store.
