Description

[Detailed Description of the Invention] This invention relates to a heating element and a cooling element that can maintain a desired temperature for a long period of time.

Various types of heating elements including a heating agent and a heating medium, or cooling bodies including a freezing agent and a cooling medium have been devised.

(Hereinafter, the exothermic agent and the cryogenic agent will be collectively referred to as simply a drug, the exothermic medium, and the cryogenic agent will be collectively referred to as simply a medium, and the exothermic body and the cooling body will be collectively referred to as simply a hot and cold body.)

In this hot/cold body, for example, the pack is divided into two chambers using a dividing clamp, and one chamber contains a drug such as ammonium nitrate, and the other chamber contains a medium such as water or water gel. At the time of use, the split clamp is removed and both are mixed and used for the intended purpose, or the pack contains a single pouch containing the drug, the remaining part of the pack is filled with the medium and sealed, and then used. There are products that serve this purpose by breaking a single pouch inside the pack by pressing or other means to mix the two, but in both cases, all the drugs come into contact with the vehicle at once, causing rapid heat generation or Negative heat is produced, and therefore only a short-term heating or cooling effect can be obtained, making it extremely difficult to maintain a desired and constant temperature for a long period of time.

This idea was devised after extensive research in order to improve the above-mentioned drawbacks of conventional hot/cold bodies and to obtain a hot/cold body that maintains a desired temperature for a long period of time. In a heat-generating pack or heat-absorbing pack in which both are housed in one pack and the two are brought into contact and reacted or dissolved to generate heat or absorb heat, the pack is divided into two or more chambers by an isolation means, and each chamber has a Containing only either the drug or the vehicle and dividing it into a drug chamber and a vehicle chamber, and storing a part or the entire amount of the drug and/or vehicle in one or more pouches having an easily breakable plate part. , the sachet is stored in a pack, and a split clamp is used as a means for isolating the hot and cold body, and it has a plate part that can be easily destroyed. Two measures using isolation bags are applied.

When using the hot/cold body of this invention, it first releases the isolation of the pack.

That is, the drug layer and the medium layer inside the pack are brought into contact by removing the splitting clamp or breaking the isolation bag by pressing or pulling from the outside of the pack.

Next, the pouches stored in the pack are sequentially destroyed by pressure from the outside of the pack as necessary, and the two agents are brought into contact with each other in stages to serve the purpose of heat generation or cooling.

Then, by applying pressure to the mandrel 12, the mandrel 12 is fitted into the receiving part 11 along with the surfaces 14 and 13 of the pack 2, and the pack 2 is divided into two chambers as shown in the opening.

The dividing clamp 7 shown in FIG. 9 is simple, but the dividing clamp 7 is not limited to the above-mentioned clamp as long as it completely divides the pack 2 into two chambers and is releasable. , any form of clamp may be applied.

The feature of this device is that a part of the medicine inside the isolated medicine chamber and/or medium chamber is divided into pouches 4 having abdomens that can be easily destroyed and housed therein.

Here, the pouch 4 must be made of a material that can be easily destroyed by pressing or pulling during use to form the bag body 3.

The bag body 3 of this pouch 4 is generally made of a soft and thin synthetic resin film, such as polyethylene, polyvinyl chloride, nylon, etc., as a material that satisfies the above conditions.
A film such as polyester is used.

In short, the bag bodies of these pouches 4 are made of water-resistant, chemical-resistant, soft, and thin material, and have brittle parts processed so that they can be easily broken from the outside of the pack during use. Good to have.

The pouch 4 is built in to provide a desired temperature to the hot/cold body, and its size can be any size and shape depending on the size of the hot/cold body, purpose, etc.

In addition, the shape of the pouch 4 is circular (disc-shaped,
It goes without saying that '', which indicates a spherical shape, can take various shapes such as a rectangular parallelepiped, a rectangular parallelepiped, an ellipsoid, and other shapes, and these pouches may also be connected.

As mentioned above, the pack 2 in the hot/cold body 1 contains the medicine 5,
A pack that stores a medium 6, a small bag 4 containing these drugs, mediums, etc., and an isolation bag 8 shown in FIG. 8, and is easily destroyed during handling, storage, use, etc. This pack is generally made of polyethylene, polyvinylidene chloride, polyvinyl chloride, nylon, polyester, and other soft synthetic resin films or sheets. Alternatively, heat-insulating sheets such as foam or laminates with cloth may also be used.

Furthermore, as mentioned above, the isolation bag 8 used as one aspect of the isolation means in this invention isolates the drug layer or medium layer from its corresponding drug, and has water resistance and chemical resistance. It is also desirable to use a material that can be easily destroyed during use, and the material used for the bag body 3, which is the bag body of the small bag 4, can be used as this material.

The hot/cold body of this invention is a combination of chemicals such as an exothermic agent and an exothermic medium, or a cryogen and a cryogenic agent, and when both agents are mixed and brought into contact, a rapid fever is generated. All of the drugs that are generally applied to these forms of hot and cold bodies can be used.

This applicable agent can be used as an exothermic agent in a heating element, such as calcium oxide, sodium hydroxide, anhydrous calcium chloride, anhydrous sodium carbonate, etc., and any other substance that can generate heat in the above medium, and as a cryogenic agent in a cooling element. , for example, ammonium nitrate, ammonium chloride, or urea, and any substance having a negative heat of solution can be used as the cryogenic agent.
