Description

Defense bag with bulletproof performance

In the present invention, a superabsorbent polymer is placed in a bag, and water is supplied to the superabsorbent polymer in the bag, thereby expanding the superabsorbent polymer and making it possible to receive a shot bullet or the like. It is about a defense bag. Background art

Various structures are used to stop the prevailing external force applied from the outside. For example, barricades use concrete, metal, earth and sand, wood, etc. to block or deter flying testicles and fragments. Built. In particular, when trying to counter terrorist activities, it is important to have resistance against small arms attacks, and it is effective to build a barricade with earthenware. However, effective defenses cannot be taken if there is no available material nearby.

For this reason, utility model registration No. 3 1 0 5 8 8 7 is proposed as an anti-corrosion soil that can be expected to have a bulletproof effect that is equivalent in strength to a sandbag filled with earth and sand. Has been. This device has the advantage that the water storage polymer in a powder form is enclosed in a bag and the bag is formed in a flat shape, so that the storage space may be narrow during transportation and storage.

However, this idea only describes that the water-absorbing polymer is enclosed in a bag and the bag is formed in a cave-like shape, so that the method of swelling will be a problem. In this device, a water-absorbing polymer is enclosed in an inner bag made of cotton and put in a hemp bag to make the whole flat, so that when it swells, the center is inflated and gradually becomes thinner toward the periphery, and the thickness of the bag is uniform. Not like that. This is also shown in Fig. 2 in the publication of the device, and when such inflated bags are stacked, a gap is created at the end of the bag that is insufficient in thickness, allowing the bullets to pass through without interruption. Cause fear of As a result, if a considerable amount of bags are not used, it will be useless, work efficiency will not be good, and the bags will have to be stacked in multiple stages, so it will become unstable, and anxiety will remain as a soil that actually entrusts life. Disclosure of the invention

The present invention has been made paying attention to the above points, and the problem is that it is easy to handle, can be expanded in a matter of minutes regardless of who is handling it, and has a bulletproof performance capable of receiving a shot bullet or the like. It is to provide a defense bag having. Another object of the present invention is to provide a defense bag having a bulletproof performance in which moisture supply to the superabsorbent polymer is performed quickly and reliably.

In order to solve the above-mentioned problems, the present invention provides a superabsorbent polymer placed in a bag, and supplies water to the superabsorbent polymer in the bag to expand the superabsorbent polymer. About the defense bag that can receive the bullets that are inserted, the water-soluble paper is used to form a sachet, and the sachet is filled with the required amount of superabsorbent polymer, and then the required amount of superabsorbent polymer is obtained. Prepare a protective bag body of the appropriate size, and form a large number of water introduction holes to supply moisture to the highly water-absorbent polymer in the entire body of the protective bag, and fill the body of the protective bag with the highly water-absorbent polymer. The measures of arranging and configuring the sachets are taken.

The defense bag according to the present invention expands the volume of the superabsorbent polymer by supplying moisture to the superabsorbent polymer in the bag, and can receive a bullet to be shot as a gel. Examples of superabsorbent polymers include crosslinked polyacrylate powder A powdery one is good, which is insoluble in water, but swells when absorbed.

Water other than fresh water, such as seawater, can be used, but when seawater is used, it is desirable to use a cross-linked polyacrylic acid metal salt at a concentration of 90 parts by weight or more. Superabsorbent polymers have been used for soil hygiene and horticultural applications such as sanitary materials such as disposable diapers, but also in the present invention. Superabsorbent polymers can be used.

The superabsorbent polymer is disposed in the body of the protective bag. For this purpose, a pouch is formed using water-soluble paper, and the superabsorbent polymer is filled therein. The sachet filled with the super absorbent polymer shall be placed in the position of the protective bag body where water can be absorbed most efficiently, so that no matter who handles it, it will surely absorb water in the shortest time. The use of water-soluble paper as a sachet material promotes expansion due to diffusion of the superabsorbent polymer. The performance required for the decomposition of the water-soluble paper is preferably within a few tens of seconds, more preferably within a few seconds to a few tens of seconds.

Another means for improving the water absorption efficiency is a large number of water introduction holes formed in the entire body of the protective bag. The body of the protective bag is flat from the viewpoint of storage and transportation, and when it is inflated by water absorption, the body of the protective bag is sufficient, for example, 15 to 20 centimeters or more like a cement bag or a grain bag. It becomes a rectangular parallelepiped type with a thickness and can be stacked stably. In addition, it is understood that the water introduction hole serves as a pressure escape path inside the expanded superabsorbent polymer, and it is thought that it also has the effect of inducing the movement path of the testicles actually driven into the superabsorbent polymer. .

In the defense bag having the bulletproof performance of the present invention configured as described above, the defense bag body may have a layered structure composed of a plurality of water-resistant kraft papers (the invention according to claim 2). ) Kraft paper is tough and flexible as paper, and it is more preferable as a protective bag by having water resistance. It is desired that the body of the protective bag has a gusseted portion, and it is expected that the gusseted portion will expand into a rectangular parallelepiped with sufficient thickness.

In order to arrange a sachet filled with a superabsorbent polymer in the body of the protective bag, it is possible to prepare a frame for housing the sachet and to fix the sachet inside the frame (claim 3). Invention). The frame is placed around the protective bag body until moisture is supplied to the superabsorbent polymer, and the sachet filled with the superabsorbent polymer is not pressed too much. Retain space. The retained space attracts the supplied moisture and makes it easier for the moisture to penetrate into the superabsorbent polymer.

It is desirable to use a woven fabric made of synthetic fiber to form a reinforcing means for increasing the strength of the protective bag body, and to cover the inner surface of the protective bag body using the reinforcing means (claim 4) Described invention). Being a woven fabric is a structure that is desired to allow moisture to penetrate inside, and at the same time satisfies the condition of a tough structure. The reinforcing means is not limited to one layer. As described in claim 2, when the main body of the protective bag has a three-layer structure, one layer is interposed between them, for a total of two layers, depending on the target strength. Can be set.

The reinforcing means includes those laminated on the surface of the body of the protective bag and tubes that are independent of the water-resistant kraft paper (the invention according to claim 5). This means that the reinforcing means can take two different forms: one that is laminated and integrated on the surface of the main body of the protective bag and another that is independent from the water-resistant craft paper. The integrated one does not need to be tubular because it has a cylindrical structure at the time of bag making, but it is desirable to adopt a tubular structure because an independent separate one does not necessarily have a cylindrical shape.

The outer surface of the protective bag body can be covered with an exterior body to increase the structural strength (the invention according to claim 6). The exterior body is necessary for preventing slippage in the usage method of stacking the defense bags, and is an effective means. One desirable protective bag body non-slip means is a hemp bag or a strength and friction equivalent to or higher than that of a hemp bag, It is an exterior body to be housed inside (the invention according to claim 7). Another effective anti-slip means is to apply a resin or the like for increasing friction to the flat surface of the body of the protective bag. Synthetic resin bags can be used in place of the hemp bags and are expensive, but in this case as well, the effect of improving the strength and the effect of preventing slipping can be obtained similarly.

Since the present invention is constructed and operates as described above, and anyone can handle it, it is surely easy to handle that it expands in a few minutes. There is no variation in the bulletproof performance of the constructed protective bags, and the safety is extremely high. Further, in the present invention, a large number of water conduction holes are formed in the entire body of the protective bag to facilitate the supply of moisture to the superabsorbent polymer, and a small bag filled with a superabsorbent polymer is disposed in the protective bag body. As a result, for example, the expansion of the superabsorbent polymer is started from the central portion of the body of the protective bag, and there is an effect that the whole is quickly and surely extended. Since the protective bag of the present invention expands in a substantially rectangular parallelepiped shape, when the protective bags are pressed against each other, the side edges of the end portions are almost in close contact with each other, and almost no gap is formed, so that a complete ballistic resistance can be obtained.

Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 is a perspective view showing an example of a defense bag 10 having bulletproof performance according to the present invention, and a powdery superabsorbent polymer is suitable for a small bag 11 formed using water-soluble paper. Is filled.

Water-soluble paper is used to hold a powdery superabsorbent polymer in the form of a sachet 1 1 until it is used. When water is supplied, it dissolves quickly and the protective bag body 1 5 It is evenly dispersed inside and acts so as to expand. A sachet 11 filled with an appropriate amount of superabsorbent polymer is housed in a frame 12 that is slightly larger than that in order to secure a space around it. The illustrated frame 1 2 is formed using corrugated pole paper, and the sachet 1 1 has a structure that fits with a gap g around it. This is a configuration in which 1 is bonded and fixed. 1 4 shows an adhesion part.

The main body of the protective bag 15 is composed of a plurality of water-resistant kraft papers 16 and has a size corresponding to the required amount of superabsorbent polymer. In the example, the protective bag body 25 has a layered structure. (See Figure 4). The illustrated water-resistant kraft paper 16 is a poly Reinforcement means by laminating a woven fabric 17 made of ren fibers on the surface (inner surface), and making a cylinder using water-resistant kraft paper 16 laminated with the woven fabric 17 by, for example, heat welding The protective bag body 15 is formed through the bag making process. The material of the woven fabric 17 is not limited to polyethylene, but polypropylene and other materials can also be used, but it is necessary to have a knitted structure to ensure water permeability.

As another means of reinforcement, weaving tube 18 independent of water-resistant kraft paper 16 is used together (see Fig. 5). This woven tube 18 is arranged in the innermost layer of the water-resistant kraft paper bag, and has a cylindrical structure (tube-like structure), and the opening at both ends of the cylinder is a sealing band in the bag making process. 1 Closed by 9. The sachet 11 is placed in the main body before being closed by the sealing band 19. The material of the woven fabric tube 18 can also be the same polyethylene, polypropylene, or the like as the woven fabric 17 described above. However, in the illustrated example, the woven fabric 17 disposed on the outer side is closer to the film. In contrast to the flatness of the water-resistant kraft paper 16, the material of the woven tube 18 is narrower and thicker.

A large number of water guide holes 20 for supplying moisture to the superabsorbent polymer are formed in the entire defense bag body 15 having the above-described configuration. The water guide holes 20 are formed in such a distribution that moisture can be supplied quickly from all directions to the sachets 11 of the sachet arrangement portion 21 set in the defense bag body. Further, non-porous portions 2 3 and 24 are provided on both side portions along the gusset portion 22 and both end portions along the sealing band 19, respectively. The non-porous portions 2 3 and 24 are provided so as to surround the water guide hole 2 に in a frame shape, and function to direct or limit the pressure escape field inside the superabsorbent polymer toward the water guide hole 20. Since the non-hole parts 2 3 and 2 4 form the side surface around the rectangular parallelepiped defense bag 10, if a hole is drilled here, it is possible to make the driven testicles jump out diagonally instead of up and down It will make sex, which is not preferable.

Further, the protective bag body 15 is combined with, for example, a hemp bag as an exterior body 25 as strength improvement means and anti-slip means. The exterior body 25 has a size and shape that can cover the entire body of the protective bag, and has a bag structure in which two or three sides are closed. Put the defense bag body 1 5 inside. As the exterior body 25, it is also possible to apply other methods such as applying a foamable resin to an important portion of the flat surface of the protective bag body 15 or applying a rubber band to the protective bag body 15. When using a hemp bag as the exterior body 25, after the protective bag body 15 is housed inside, the end opening 26 is securely closed by appropriate means such as thread, string, wire or stable. It is desirable to place it.

Next, a method of using the defense bag 10 of the present invention configured as described above, an anti-fouling effect, and the like will be described. First, when the protective bag 10 of the present invention was immersed in a water-filled tank and water was supplied to the superabsorbent polymer, the expansion was completed in 6 to 7 minutes, and the height was around 20 centimeters. I got a defense bag 10 weighing about 25 kilograms. FIG. 2 shows the appearance of the inflated protective bag 10 of the present invention, and FIG. 3 shows the protective bag 1 in which the protective bag 10 of FIG.

0 appearance is shown. As shown in the figure, the defense bag 10 of the present invention forms a thick rectangular parallelepiped, and is almost in close contact when the ends are pressed together. Figure 6 shows the inflated defense bag 10 of the present invention stacked on a wooden pallet in three rows in the front and back and two steps in the top and bottom. Testicles with 6 A type 1 rifle (caliber 5.

5 6 mm, dose 5 5 durlane). When 5 shots were shot in a single shot, they were all received by the defense bag 10 of the present invention, and when 30 shots were fired continuously, 1 2 shots went down from the top row in the front row, and 16 shots came from the top row in the middle row. As a result, two shots went down from the upper row of the last row, and there was no one that penetrated the defense bag row of the present invention.

Fig. 7 shows a state in which the protective bags 10 of the present invention inflated on a wooden pallet are vertically arranged in three rows in the front and back, and M 1 6 A 1 from a point 2 4 meters away from this target. A bullet (caliber 5.56 mm, dose 55 grains) was driven by a type rifle. Fired 20 shots, but all stayed in one of the defense bags 10 and none of them penetrated. These gun tests were conducted in foreign countries. In Fig.6 and Fig.7, 1 2 b, 1 6 b, etc. indicate the number of fired fire.

As described above, the protective bag 10 of the present invention exhibited excellent bulletproof performance, but in addition, it was found that the protective bag 10 is also characteristic in that it does not cause deformation or damage to the testicles. As described above, even if the direction was changed by the bulletproof bag 10 and it slipped down or up, it was decelerated to a sufficiently safe low speed, and the bullet was recovered as it was without deformation or scratches. The used protective bag 10 can be separated into powder and water by adding calcium chloride or the like. Industrial applicability

The bullet-proof defense bag according to the present invention can be used as a defense wall against terrorist acts and the attack of Tokyo Metropolitan guerrillas, and even if water is available even in a city where it is difficult to obtain earth and sand. It can be expanded and used as a sandbag, and it can be used for various purposes as a disaster prevention product, such as measures against floods caused by heavy rains, or measures against inflow of water into openings in underground structures.
