Description

  The present invention relates to a carcass storage and storage bag for storing a human or animal carcass and storing it for a long period of time.

  In natural disasters such as earthquakes, fires, floods, and accidents such as trains, automobiles, and aircraft, many casualties are expected. In such a case, the body of a large number of dead people, that is, a system that can quickly store the dead body and transport it to the required place, especially when it is necessary to examine the body, etc. Needed.

  Conventionally, as this type of corpse storage and storage system, when storing the corpse in a closed space such as a bag, a coolant such as a cold storage agent or a block of dry ice has been used. Replenishment is necessary, especially when many bodies need to be preserved.

  In addition, for example, Patent Documents 1, 2, and 3 propose a body storage and storage system including a cooling device with a refrigerant compressor that uses a cooling cycle based on refrigerant compression and expansion.

  However, in the case of this type of corpse storage and storage system, it is necessary to use a cooling and compression device driven by an electric motor. Therefore, it is necessary to secure a power source during transportation of the corpse, and the weight increases. However, there is a drawback that the number of storage and the storage cost are increased.

  Furthermore, the bag body is formed of a multilayer structure combining a plurality of heat-insulating and confidential materials, and the body is stored in an opening that can be sealed after the body is stored, and is added to the bag body. Patent Document 4 proposes a body storage and storage system configured to inject a liquefied gas from a liquefied gas source to rapidly cool the body while making the inside substantially oxygen-free through a single communicating portion. .

  In the above-described body storage and storage system, according to the bag body provided with two communication portions, first, the body is stored from the opening portion of the bag body, the opening portion is sealed, and then the high pressure cylinder is connected to one communication portion. Before connecting the liquefied gas, open the valve of the other communication part, and then open the valve of the high-pressure cylinder, so that the liquefied gas is passed through the one communication part inside the bag body. And the air inside the bag body is automatically discharged through the other communication portion, and the inside of the bag body is rapidly cooled, so that the body can be preserved. By repeating the injection repeatedly, the body preservation period can be extended.

  According to the bag body provided with one communication portion, it is possible to cope with this by performing an operation of injecting liquefied gas after performing an air discharge operation in advance through a common communication portion.

  However, in the case of this type of body storage and storage system, a high-pressure cylinder is indispensable, and regarding the operation content, when the liquefied gas is injected, the valve of the communication part must be frequently opened and closed. When it is necessary to preserve the body of the body, there is a disadvantage that the number of preservation and the preservation cost are increased.

  As a storage bag for carcasses of animals such as dogs and cats, it has waterproof, deodorant and antiseptic effects on the plastic material of the storage bag, and the opening part can be opened and closed with Velcro (registered trademark), fasteners, etc. This is proposed in Patent Document 5.

  The purpose of this storage bag is to facilitate the storage and transport of animal corpses, so that the corpse should be kept in place between death and incineration and burial and sealed for a relatively long period of time. I don't have it. Therefore, during the preservation of the corpse, there is a drawback that bad odor due to the decay leaks to the outside through the opening of the storage bag or permeates the material of the storage bag.

As an animal carcass preservation device, Patent Document 6 proposes a structure composed of a bag-like water-absorbing sheet for placing a carcass and a spray device containing a preservative.

  The water-absorbing sheet of this storage device has a structure in which a moisture-permeable resin film sprayed with a preservative using a spray device and a moisture-impermeable resin film are laminated on both sides of a sheet-like water-absorbing member into a bag shape. Therefore, it does not have a sealed structure. For this reason, when it is desired to place the corpse and store it for a relatively long period of time, there is a disadvantage that malodor due to decay of the corpse easily diffuses from the water-absorbing sheet to the outside during storage.

  As a sealed bag for animal corpses, it is equipped with paper or non-woven fabric that has been impregnated with ingredients that have high anti-corruption and deodorizing effects. A structure is proposed in Patent Document 7.

However, the purpose of this invention is to ensure the safety and facilitation of the treatment of animal carcasses by sealing the carcass and preventing the decay and deodorizing inside the bag. , No disclosure. For this reason, when it is desired to place the corpse and store it for a relatively long period of time, there is a high possibility that malodor due to the decay of the corpse will diffuse from the inside of the sealed bag to the outside during storage.
JP-A-1-97455 Japanese Patent Laid-Open No. 2-95366 JP-A-4-244153 JP-A-9-286701 Utility Model Registration No. 3071935 Utility Model Registration No. 3046073 JP-A-10-203576

  Therefore, an object of the present invention is to provide a human or animal carcass storage and storage bag in which the disadvantages of the above-described conventional body storage and storage system and animal carcass storage bag / storage device are improved.

  In order to solve the above-mentioned problems, the corpse storage and storage bag of the present invention is made of a multilayer structure sheet in which plastic films containing antibacterial / deodorant are laminated, has a width and a length capable of storing a corpse, In a corpse storage and storage bag comprising a bag body having an opening that can be opened at a part of the multilayer structure sheet, the multilayer structure sheet is made of a three-layer structure plastic sheet of an antibacterial / deodorant-containing polyethylene film, polyvinyl alcohol film and polypropylene film The opening is configured to be sealable with a chuck.

  The storage and storage bag uses a polyethylene film containing antibacterial and deodorant for the inner layer of the multilayer structure sheet in contact with the corpse. Moreover, while suppressing generation | occurrence | production of a malodor, and transparency is comparatively favorable, the corpse preservation | save bag which can see the contents visually can be obtained. In addition, since the polyethylene film has excellent moisture barrier properties, there is no risk that moisture such as excrement and secretions from the corpse will permeate the inner layer.

  If a low-density polyethylene film is used as the polyethylene film, the heat-sealability and transparency are excellent. Therefore, it is easy to weld the periphery of the bag with a bag making machine, and a transparent corpse storage bag that ensures strong sealing strength. Can be easily obtained. In addition, if a polyethylene film containing an antibacterial / deodorant at high density is used, bacteria attached to the corpse and parasites such as moths and spiders will die in a short period of time, and as a result, the progress of decay and the generation of odors will be almost impossible. A storage and storage bag that can be completely suppressed can be obtained.

  Since the storage and storage bag uses a polyvinyl alcohol film for the intermediate layer of the multilayer structure sheet, it has excellent gas barrier properties and transparency, so that the gas generated by the progress of decay passes through the intermediate layer and is released to the outside of the bag. In addition, it is possible to easily obtain a transparent corpse storage bag in which outside air or the like does not pass through the intermediate layer and enter the bag.

  The storage and storage bag uses a polypropylene film for the outer layer of the multilayer structure sheet, so it has good mechanical strength and transparency and excellent colorability, so it is resistant to impact, can withstand long-term use, and can be printed on the surface. A glossy transparent high-quality corpse storage bag can be easily obtained.

  Since the storage and storage bag is configured so that the opening can be sealed with a chuck, the odor remaining inside does not leak out to the outside of the bag through the opening, and forms a transparent corpse storage bag. Can be seen from outside the bag during long-term storage.

  In claim 2, the three-layer structure plastic sheet is composed of a laminated sheet having a polyethylene film thickness of 100 micrometers, a polyvinyl alcohol film thickness of 12 micrometers, and a polypropylene film thickness of 20 micrometers. Therefore, it is possible to obtain a storage and storage bag that can store a corpse for a long period of time with a simple structure without adopting a special body storage and storage system as in the prior art.

  In addition, the storage and storage bag is composed of a laminated structure sheet with a total thickness of 132 micrometers, so it can be folded thinly and is convenient for storing many items in case of natural disasters or accidents. By simply pulling the front and back surfaces up and down, a box-shaped storage container that is stable in form can be easily formed, and therefore, a large number of corpses can be stored easily.

  According to the third aspect of the present invention, since the opening / closing valve for exhaust is provided in the bag body, the cadaver is stored, the opening is sealed by the chuck, the storage storage bag is sealed, and then the bag body is simply pressed to remain inside the body. Exhausted air or subsequently generated gas can be discharged. Therefore, the inside of the bag can be easily brought into an oxygen-free state while being sealed with a chuck.

  In claim 4, since a linear low density polyethylene film is used as the polyethylene film, it is excellent in tearing, tensile, puncture strength and pinhole resistance, so it is strong and has excellent heat sealability and transparency. You can get a bag.

  In claim 5, since the stretched polyvinyl alcohol film is used as the polyvinyl alcohol film, a super gas barrier storage and storage bag can be obtained.

  In claim 6, since a stretched polypropylene film is used as the polypropylene film, the mechanical strength is improved and a further high-quality storage and storage bag can be obtained.

  The corpse storage and storage bag of the present invention has an effect of forming a sealed bag during storage of the corpse for a long period of time, suppressing the progress of decay and generation of malodor, and preventing leakage of moisture, gas, etc. to the outside. . Therefore, the corpse storage and storage bag of the present invention can be kept indoors at room temperature for a long time without cooling with dry ice or the like. In particular, pathogens such as SARS (Severe Acute Respiratory Syndrome) virus that may propagate in an animal body and infect humans may be killed in the sealed bag of the present invention or transmitted to the outside of the sealed bag. Absent.

  Furthermore, the corpse storage and storage bag of the present invention is convenient for storage, facilitates the cadaver storage process, and has an effect that the corpse can be visually observed from the outside even during storage.

  An exemplary embodiment of the present invention will be described with reference to the accompanying drawings. 1 is a front view of a state in which the corpse storage and storage bag of the present invention is unfolded, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and FIG. 3 is a perspective view of the state of use of the corpse storage and storage bag of the present invention. Show.

  As shown in FIG. 1, the main body 7 of the corpse storage and storage bag of the present invention has a pair of upper and lower plastic sheets 1 and 2 and a pair of side portions having a width, length and thickness that can accommodate animals, for example, dogs. The plastic sheets 3 and 4 are overlapped, using a bag making machine, except for the side having the opening 5, the overlapped sides are heat-sealed to form a seal portion 6, and one side of the upper plastic sheet 1 The container 5 is configured as a box-shaped storage and storage container having an opening 5. The opening 5 is formed so as to be hermetically sealed by a chuck 8.

  As shown in FIG. 2, the upper, lower and side plastic sheets 1, 2, 3, and 4 constituting the main body 7 of the storage and storage bag are linear low density containing antibacterial and deodorant as inner layers, respectively. A three-layer structure sheet is formed by laminating a polyethylene film 9, a stretched polyvinyl alcohol film 10 as an intermediate layer, and a stretched polypropylene film 11 as an outer layer.

  The linear low-density polyethylene film 9 contains the bitterness ingredient “catechin” contained in plants in a high density over the entire thickness of 100 μm as an antibacterial / deodorant, It has an odorous power and forms a strong inner layer. For this reason, bacteria and parasites such as moths and pupae that adhere to the corpse of the dog will die within a few hours, so their breeding and the accompanying decay and odor are almost completely suppressed, and the corpse is stored and transported.・ Damage due to tearing or piercing of the inner layer during resting is prevented. Furthermore, it is possible to prevent moisture discharged from the corpse and secreted from passing through the inner layer and released to the outside of the bag body 7.

  The antibacterial / deodorant is not limited to “catechin”, but an antibacterial agent such as diphenyl air or silicon quaternary ammonium salt, or a deodorant such as metal salt such as copper, iron, silver or zinc. An agent may be used.

  A linear low-density polyethylene film 9 having a thickness of 100 micrometers is laminated with a stretched polyvinyl alcohol film 10 having a thickness of 12 micrometers and a stretched polypropylene film 11 having a thickness of 20 micrometers, and has a total thickness of 132 micrometers. Metric three-layer structure sheets 1, 2, 3, 4 are formed. As a result, the storage and storage bag body 7 having high gas barrier properties, high mechanical strength, transparency and high quality can be obtained, so that the gas generated by the progress of decay permeates through the intermediate layer and the outer layer, and the outside of the bag body 7 And the outside air is prevented from entering the bag body 7.

  The chuck 8 is composed of a pair of concave and convex fitting type plastic chuck sheets heat-sealed on the inner surface of one side of the bag body 7 having the opening 5. Thereby, the bag main body 7 forms a sealing bag in which the opening 5 can be opened, and prevents gas and liquid inside and outside from leaking out and entering through the opening 5. The chuck is not limited to the concave-convex fitting structure, and may have another structure, or may be combined with other sealing means such as an adhesive system.

  FIG. 3 shows a use state in which the corpse of the dog is stored in the bag body 7. Since the bag body 7 is composed of plastic sheets 1, 2, 3, and 4 having a total thickness of 132 micrometers, the bag body 7 can be folded thinly during storage, and is folded up to form the front and back surfaces during use. -A box-shaped storage container that is stable in form can be easily formed simply by picking the lower plastic sheets 1 and 2 and pulling them up and down and spreading them. Therefore, the corpse can be stored easily, and the storage and storage bag of the present invention serves as a bag.

  As shown in FIGS. 1 and 3, an exhaust on-off valve 12 is provided at a predetermined position of the upper plastic sheet 1 of the bag body 7. The on-off valve 12 is configured to discharge the air inside the bag body 7 by pressing the upper plastic sheet 1. Therefore, even after the opening 5 is sealed with the chuck 8 and the bag main body 7 is sealed after the corpse is stored, the inside of the bag main body 7 can be easily brought into an oxygen-free state. Therefore, the gas generated by the progress of the decay of the corpse during refuge can be easily discharged from the sealed bag body 7.

  The position where the on-off valve 12 is provided is not limited to one end of the upper plastic sheet 1 as shown, and may be provided at an arbitrary position of the bag body 7. Further, the exhaust on-off valve 12 may have any structure. It is preferable to attach an antibacterial deodorizing filter to the on-off valve 12 because the contaminated internal gas can be easily purified and discharged.

  The polyethylene film, polyvinyl alcohol film and polypropylene film constituting the three-layer structure plastic sheet are highly transparent, and the polypropylene film is further colored, so that the bag body 7 can be configured so that the inside corpse can be seen through from the outside of the bag. After bag making, various patterns and colors can be easily applied to the outer surface. In addition, since any plastic film is a material that can be incinerated, the storage bag of the present invention does not generate toxic gas even if it is subjected to cremation with a corpse after refuge.

Using the carcass storage preservation bag of the said Example, it tested 3 times using the carcass of a small dog and a cat (about 10 kilograms) under the following conditions. As a result, in all cases, the progress of the decay of the specimen was hardly observed, and therefore, the storage bag was not expanded due to the generation of gas. In addition, there was no evidence that moisture such as effluents and secretions from the specimen leaked out of the bag. Furthermore, no damage was observed in the storage bag during storage.
