Description

  The present invention relates to a gas diffusing bag-like body capable of diffusing a very small amount of gas over a long period of time.

  Conventionally, this type of gas-diffusing bag-like body can generate chlorine dioxide as a sterilizing and deodorizing agent, for example, as shown in FIG. 4, by reacting with chlorite and this chlorite in water. There is a gas permeable outer bag 11 formed by sealing a compound with an easily breakable inner bag 12 for sealing an aqueous medium (Patent Document 1).

  The conventional sterilization and deodorant configured as described above has an effect that it can be used easily and safely on various objects and chlorine dioxide can be easily generated on the spot. Moreover, the generation period of chlorine dioxide can be easily controlled by adjusting the composition and ratio of the encapsulated compound and the aqueous solvent, and there is an effect that the problem of residual toxicity does not occur.

  Further, this type of gas-diffusing bag-like body is an oxygen-generating bag, for example, as shown in FIG. 5, a peroxide decomposition solution or an inner bag 21 set to a strength that can be ruptured by a predetermined impact. A decomposing agent 22 made of a suspension is sealed, and the inner bag 21 and the peroxide as the oxygen generating agent 23 are sealed in a water-impermeable inner bag 24 and a predetermined number of fine particles are contained in the inner bag 24. There is one in which a vent hole 25 is formed and the inner bag 24 is sealed in an outer bag 26 that is impermeable to moisture and gas permeable (Patent Document 2).

  The conventional oxygen generating bag configured as described above has an effect that the impact when the inner bag 21 is ruptured can be buffered by the inner bag 24 and the outer bag 26 can be reliably prevented from being damaged. is doing. Further, the oxygen gas generated in the inner bag 24 is once retained in the outer bag 26 through the fine vent 25, and then released from the entire surface by the gas permeation of the outer bag 26. Oxygen gas pressure per unit area is reduced, so that it is possible not only to avoid a rupture accident, but also to reduce the manufacturing cost because the outer bag 26 can be made of less expensive materials. It has the effect of becoming possible.

  Further, this type of gas diffusing bag-like body is a carbon dioxide gas supply device, for example, as shown in FIG. 6, a bag 32 containing water 31 containing carbohydrates and a carrier 34 containing dried yeast 33. And a heat insulating bag 36 containing the deodorizer 35 and containing the bag 32 and the carrier 34, and a bag 37 having carbon dioxide permeability and containing the heat insulating bag 36 (Patent Document 3). ).

The conventional carbon dioxide supply apparatus configured as described above is a safe apparatus that is inexpensive and easy to handle without using expensive and complicated containers such as high-pressure cylinders. At the same time as absorbing oxygen in the atmosphere. Furthermore, since the structure is simple and small and light, it has the effect that it can be enclosed in food and stored in a refrigerator.

  In the conventional gas diffusion bag-like body, in order to generate a gas such as chlorine dioxide, oxygen, carbon dioxide, etc., in the case shown in FIG. 4, pressure is applied to the gas permeable outer bag 11 with a palm or a finger. In the case shown in FIG. 5, the inner bag 12 housed therein is broken and the contents of the inner bag 12 and the contents of the gas permeable outer bag 11 are reacted to provide gas permeability. As shown in FIG. 6, by applying pressure to the outer bag 26 in the same manner, breaking the inner bag 21 housed inside, and reacting the contents of the inner bag 21 and the contents of the inner bag 24. Then, pressure is similarly applied to the bag 37 having carbon dioxide gas permeability, the bag 32 accommodated in the bag is broken, and the contents of the bag 32 and the carrier 34 are reacted, Is going.

  However, in the conventional gas diffusion bag-like body, the inner bag 12 housed in the gas permeable outer bag 11, the inner bag 21 housed in the outer bag 26, and the bag 32 housed in the bag 37 are included. In any case, since it cannot be visually confirmed from the outside, it is inconvenient even if pressure is applied with a palm or a finger, and it is not known whether the inner bag 12, the inner bag 21, and the bag 32 are completely broken. It had the problem of being. Further, in order to completely break the inner bag 12, the inner bag 21, and the bag 32, if too much pressure is applied by a palm or a finger, the gas permeable outer bag 11, the outer bag 16, and the bag 37 are also broken. There was a problem that there was a possibility of doing.

  Therefore, the present invention solves the above-mentioned conventional problems, and makes it possible to visually confirm the mixed state of substances that generate gases such as chlorine dioxide, oxygen, carbon dioxide, etc. Since the operation is easy, the purpose of the present invention is to provide a gas-dissipating bag-like body that does not cause the outer bag to break due to excessive pressure applied by a palm or a finger.

Therefore, the gas diffusing bag-like body of the present invention makes at least one of the front and back surfaces translucent and gas permeable and liquid impermeable so that the peripheral edge 1a does not open even when a predetermined pressure is applied. In the outer bag-shaped body 1, the inner bag-shaped body 2 that is liquid-impermeable and is designed to open at least a part of the peripheral edge 2a when a predetermined pressure is applied, When the first container M1 is stored in the outer bag 1 and the second container M) is stored in the inner bag 2, the first container M1 and the second container M2 are mixed. It is assumed that at least the second container M2 of the first container M1 and the second container M2 is a liquid substance, and the outer bag 1 is gas-permeable and liquid-free. A permeable synthetic resin material is layered on the nonwoven fabric 3 .

In the gas divergence bag-like body of the present invention, the gas-permeable and liquid-impermeable synthetic resin material is a thin gas-liquid impermeable synthetic resin material that is microhole processed .

  Since the gas-diffusing bag-like body of the present invention is configured as described above, it is convenient to visually confirm the mixed state of substances that generate gases such as chlorine dioxide, oxygen, and carbon dioxide. In addition, since the mixing operation is easy to perform, there is no possibility that the outer bag is broken by applying too much pressure with a palm or a finger.

  Hereinafter, embodiments of the gas-diverging bag-like body of the present invention will be described in detail based on the drawings.

  As shown in FIG. 1, the gas diffusing bag-like body of the present invention has an inner bag-like body 2 accommodated in an outer bag-like body 1 in which at least one of the front and rear surfaces is made transparent. . In addition, although the illustrated outer bag-like body 1 has a light-transmitting surface and a light-transmitting back surface, both the front and back surfaces are light-transmitting even if the surface is light-transmitting and the back surface is light-transmitting. It is good. Moreover, although it is preferable that the inner bag-like body 2 makes the front and back surfaces translucent, either one of the front and back surfaces may be translucent or the front and back surfaces may be opaque.

  The outer bag 1 has a peripheral edge 1a even when a predetermined pressure is applied, for example, by strongly bonding the peripheral edge 1a, hitting it with a palm, or pressing it with a finger. Is not opened. Furthermore, the outer bag-like body 1 has at least one of the front and back surfaces made gas permeable and liquid impermeable. That is, the outer bag 1 has a gas permeable and liquid impermeable surface and a gas and liquid impermeable back surface, and a gas and liquid impermeable surface and gas permeable and liquid impermeable back surface. Alternatively, both the front and back surfaces may be gas permeable and liquid impermeable.

  When the inner bag-like body 2 is applied with a predetermined pressure by hitting it with a palm or pressing it with a finger, for example, by making at least a part of its peripheral edge 2a a weakly bonded portion 2b, The weakly bonded portion 2b of the inner bag-like body 2 is opened. Moreover, this inner bag-shaped body 2 can also be made into the part 2b which weakly adhere | attached all the peripheral parts 2a. Further, the inner bag-like body 2 preferably has gas / liquid impermeable surfaces on the front and back surfaces, but the front and back surfaces may be gas permeable and liquid impermeable.

  The peripheral edge 1a of the outer bag-shaped body 1 and the peripheral edge 2a of the inner bag-shaped body 2 are bonded by heat sealing, ultrasonic sealing, adhesive, etc., and the shape and state of the seal, the adhesive used The adhesive strength is varied depending on the type or the like, and the adhesive strength of at least a part of the peripheral edge 2a of the inner bag-like body 2 is made smaller than the adhesive strength of the peripheral edge 1a of the outer bag-like body 1. Therefore, when a predetermined pressure is applied by hitting the outer bag 1 with a palm or pressing it with a finger, the peripheral edge 2a of the outer bag 1 is not opened, but the peripheral edge 2a of the inner bag 2 is not opened. At least a part of will be opened.

  The outer bag 1 contains the first container M1, the inner bag 2 contains the second container M2, and the first container M1 and the second container M2 are mixed. It is a substance that sometimes generates gas. In addition, at least the second container M2 of the first container M1 and the second container M2 is a liquid substance. In the figure, the first container M1 is a solid substance such as a granule or a powder, and the second container M2 is a liquid substance such as a liquid or a colloid, but the first container M1 is also a second substance M2. It is good also as a liquid substance like. Furthermore, the total volume of the inner bag-like body 2 and the first container M1 is 80% or less with respect to the inner volume of the outer bag-like body 1. In this way, when the volume ratio of the inner bag-like body 2 in the outer bag-like body 1 is reduced and the outer bag-like body 1 is pressurized by hitting it with a palm or pressing it with a finger, This pressure is easily applied to the inner bag-shaped body 2 and the outer bag-shaped body 1 is not easily broken. Further, when the first container M1 and the second container M2 are mixed and a chemical reaction starts, the color changes, and when the chemical reaction ends and no gas is generated, the color changes to a color different from that during the chemical reaction. In this case, when the chemical reaction is started, the color does not change, but when the chemical reaction is finished, the color changes to a color different from the original color, at least the front and back surfaces of the outer bag-like body 1 are made translucent. The same color as the color at the end of the chemical reaction can be printed or a sticker of the same color can be pasted on a part of one side. In this way, since the color at the time of the chemical reaction can be visually confirmed through the outer bag-shaped body 1, if the color is the same as the color printed on the outer bag-shaped body 1 or the color of the seal, the chemical reaction is performed. Knowing that it has ended, you can know when the gas has ended.

  In order to make at least one of the front and back surfaces of the outer bag-like body 1 gas permeable and liquid impermeable, the outer bag 1 may be made of a synthetic resin material such as polyethylene resin, polypropylene resin, or polybutadiene resin. In order to make the inner bag-like body 2 impermeable to gas and liquid, synthesis of acrylonitrile styrene (AS) resin, acrylonitrile butadiene styrene (ABS) resin, ethylene vinyl alcohol (EVOH) resin, vinyl chloride resin, etc. It may be made of a resin material. In addition, in order to make any one of the front and back surfaces of the outer bag-shaped body 1 gas-liquid impermeable, it is only necessary that the surface is made of the same synthetic resin material as the inner bag-shaped body 2. Needless to say.

  Furthermore, the outer bag-like body 1 is made by making a microhole process on the gas-liquid impermeable synthetic resin material such as AS resin, ABS resin, EVOH resin, vinyl chloride resin, etc. to make only gas permeable. It is good. At this time, if microhole processing is performed on a thick gas-liquid impermeable synthetic resin material, the outer bag-like body 1 becomes excellent in strength. If the thin gas-liquid impervious synthetic resin material is microhole processed, the outer bag-like body 1 becomes inferior in strength, but the microhole processed thin gas-liquid impermeable. If the synthetic resin material is made into a layered process on the nonwoven fabric 3, it will have excellent strength. That is, the outer bag-like body 1 is excellent in strength by layering the non-woven fabric 3 with the gas-permeable and liquid-impermeable synthetic resin material.

  In the gas-spreading bag-like body of the present invention, for example, when chlorine dioxide gas is generated, the first container M1 can be made of powdered saliva and the second container M2 can be made of a sodium chlorite solution. In the case of generating oxygen, the first contents M1 can be a sodium percarbonate powder, and the second contents M2 can be an aqueous solution to which manganese sulfate is added. When carbon dioxide gas is generated, the first contents M1 can be yeast dry powder such as beer yeast, and the second contents M2 can be an aqueous carbohydrate solution such as peptone or glucose.

  The gas-diffusing bag-like body of the present invention configured as described above is stored in a light-transmitting or non-light-transmitting cosmetic bag (not shown), if necessary, when not in use when gas is not diffused, When the gas is emitted, the cosmetic bag is removed and the inner bag-like body 2 containing the second container M2 in a liquid substance is struck with a palm from above the outer bag-like body 1 or pressed with a finger. When a predetermined pressure is applied to the body 2, the weakly bonded portion 2 b of the peripheral edge 2 a of the inner bag 2 is opened, and the second container M 2 flows into the outer bag 1, and the outer bag 1 A predetermined gas such as chlorine dioxide gas, oxygen, carbon dioxide gas is generated by mixing with the first container M1. In this case, even if too much pressure is applied to the outer bag-like body 1, if the outer bag-like body 1 is formed by laminating a gas-permeable and liquid-impermeable synthetic resin material on the nonwoven fabric 3, The outer bag 2 is not broken. The generated gas is emitted from the outer bag-like body 2 to the outside of the outer bag-like body 1 from at least one of the front and back surfaces that are gas-permeable and liquid-impermeable.

  Further, since the outer bag-shaped body 1 has at least one of the front and back surfaces being translucent, the first container M1 stored in the outer bag-shaped body 1 can be seen from the outside of the bag, When the weakly bonded portion 2b of the peripheral edge 2a of the shaped body 2 is opened, the state where the second container M2 is mixed with the first container M1 can be visually confirmed. In the case where the front and back surfaces of the inner bag-like body 2 are translucent, when the weakly bonded portion 2b of the peripheral edge 2a of the inner bag-like body 2 is opened, the second container M2 becomes the inner bag-like body 2. It can be confirmed whether it has completely flowed out from the inside to the outer bag-like body 1 side, which is convenient. Also, depending on the type of gas to be generated, when the second container M2 is mixed with the first container M1, the chemical reaction starts and discolors, and after the gas is generated over a long period of time, the chemical reaction ends and the color fades. In such a case, since it is possible to visually confirm the color change and the color fading, it is possible to know the gas generation end time, which is convenient. Furthermore, when the chemical reaction starts and changes color, when the chemical reaction ends and gas is no longer generated, the color changes to a color different from that at the time of the chemical reaction. When the color is changed to a color different from the original color when the process is completed, the same color as the color at the end of the chemical reaction is printed on the outer bag-like body 1 that is made transparent as described above. In this case, the color at the time of the chemical reaction can be visually confirmed. If the color is the same as the color printed on the outer bag 1 or the color of the seal, the chemical reaction This is convenient because it is possible to know the end of gas generation and the end time of gas generation.

  Therefore, the gas-diffusing bag-like body of the present invention is convenient because the mixing state of substances that generate gas such as chlorine dioxide, oxygen, and carbon dioxide gas can be visually confirmed, and the mixing operation is easy to perform. There is no possibility that the outer bag will be broken by applying too much pressure with a palm or a finger.
