Description

[Detailed description of the device] [Industrial applications]

The present invention relates to an improvement of a container, and more particularly to a composite container capable of cooling the contents filled in the container by reacting three kinds of drugs filled in the other space of the container. .

[Prior art]

By bringing the content filled in the container body into contact with the drug filled in the other space of the container, an endothermic reaction is caused,
Examples of cooling containers that can cool the contents without cooling from outside the container include sake cans and soft drink cans. In these conventional cooling containers, the reaction container for chemicals is divided into two chambers, one chamber is water and the other chamber is ammonium nitrate, sodium nitrate, potassium chloride, ammonium chloride, urea, etc., alone or in combination. It is filled and the contents are cooled by reacting these drugs when necessary. The above-mentioned agents are often more effective in cooling when used in combination than used alone. In particular, when water is reacted with a mixture of ammonium nitrate and urea, or a mixture of ammonium nitrate and ammonium chloride, the cooling effect is great. However, for example, ammonium nitrate and urea have a property that when heated in a mixed state to about 50 ° C. or more, they spontaneously react to form a double salt, and even if water is added later, the endothermic reaction does not occur. In the summer when the container of the present invention is particularly in demand, the temperature of ° C is a temperature that is relatively easily exceeded by direct sunlight, so that there is a case where there is almost no cooling effect in actual use. Further, since the reaction vessel is made of metal, there is a high risk when a corrosive agent such as ammonium chloride is used.

[Problems to be solved by the device]

According to the present invention, as described above, in the conventional cooling container, the filled cooling agent spontaneously reacts during storage, and the cooling effect cannot be sufficiently exerted during use. Does not react, it reacts for the first time at the time of use
It was desired to devise a cooling container capable of exhibiting 100% cooling effect.

[Means for Solving the Problems]

The present invention has been made to solve the above-mentioned problems of the prior art, and a reaction container for reacting a drug is provided on the upper part of the container body with a space for heat exchange between the side wall of the container body and the side wall of the reaction container. In a composite container that is provided and fixed together with a movable lid, the central portion of the movable lid is movable toward the reaction container side, and the reaction container has a step part in the middle of the side wall, and the lower part of the step part is a space for filling the drug. At the same time, a drug-filled container having a bottom sealed with a water-permeable or water-soluble sheet is placed on the step, and a sealed liquid-filled container has a top on the drug-filled container. The liquid-filled container is placed inscribed on the movable lid, the bottom of the liquid-filled container is sealed by an easily breakable sheet, and the top inscribed on the movable lid is movable inside the container. To break the easy-to-break sheet There is provided a cooling vessel, wherein a member is provided.

[Action]

Since the cooling container according to the present invention has the above-mentioned structure, when the movable lid that seals the upper opening of the container body is pushed into the drug reaction container side, the liquid filling container placed on the upper part of the drug reaction container. In the above, since the top of the liquid filling container is movable inside the container and is inscribed in the movable lid, it is pushed inward as the movable lid is pushed. Since the destruction member that breaks the sheet that seals the bottom of the liquid-filled container is provided inside the top portion that is pushed inward, the destruction member strikes the sheet and breaks it. When the sheet breaks, the liquid medicine filled in the liquid filling container flows into the medicine filling container placed on the lower side,
Reacts with the drug filled in the container. Furthermore, the liquid drug that has flowed into the drug filling container flows through the water-permeable or water-soluble sheet that seals the bottom of the drug filling container into the lowermost drug filling space, and all three types of drugs react.

【Example】

Next, the present invention will be described in detail based on the illustrated embodiment. In the figure, 1 is a container body, 2 is a reaction container for reacting a drug, and 3 is a movable lid whose central portion can be pushed into the reaction container 2 side. The container body 1 is a container made of a thin aluminum plate formed into a cylindrical shape, and forms a space A for filling the contents (for example, sake) A1 and a cylindrical reaction container 2 for reacting a drug. It is built in the upper part, and the upper opening 1a is sealed by a movable lid 3 made of aluminum.
The movable lid 3 is an absorption lid that has a central portion protruding upward and is depressed when pushed in. The movable lid 3 together with the reaction vessel 2 is a sidewall 10 of the vessel body 1.
It is fixed by being wound around the upper end portion 10a of the. Container body 1
The lower opening 1b opposite to the upper opening 1a is located at the outlet for the contents A1 and is openably sealed by the lid 4. The reaction container 2 is provided with a step portion 21 for placing the medicine filling container 5 in the middle of the side wall 20, and a space B below the step portion 21 is a space for filling the medicine B1. is there. The medicine filling container 5 is a medicine to be filled (for example, ammonium chloride) C1
It is plastic-molded so as not to be corroded by the like, and at least the bottom part is sealed with a water-permeable sheet (for example, a packaging material used for tea bag packaging) 5a. The upper part may be open. On top of the medicine filling container 5, a sealed liquid filling container 6 for filling a liquid medicine (for example, water) D1 is placed with the top 6a inscribed in the movable lid 3. The liquid filling container 6 is a container formed by integral molding of plastic and composed of a top portion 6a, a side wall 6b, and a breaking member 7.
Has a sharp cutting blade 7a at its tip and is provided in the vicinity of an easily breakable sheet (eg polyethylene film) 6c whose bottom is sealed by heat sealing. Sheet
Since 6c and the cutting blade 7a of the destruction member 7 are provided close to each other, when the movable lid 3 is pushed into the reaction container 2 side, the top portion 6a of the liquid filling container 6 is also pushed downward and the inside of the top portion 6a. The cutting blade 7a at the tip of the destruction member 7 provided at the end abuts against the sheet 6c and breaks. The space a formed between the side wall 20 of the reaction container 2 and the side wall 10 of the container body 1 is efficient between the reaction container 2 cooled by the endothermic reaction heat of the drug and the content A1 filled in the space A. It is a space provided for good heat exchange. In the cooling container filled with the contents A1 in this manner, when the movable lid 3 of the container body 1 is pushed toward the reaction container 2 side, the destruction member 7 provided on the top 6a of the liquid filling container 6 is also inside. As a result, the cutting blade 7a provided at the tip of the breaking member 7 hits the sheet 6c to break the sheet 6c, and the liquid medicine D1 filled in the liquid filling container 6 is broken from the breaking portion 6c '. It flows into the medicine filling container 5 placed below and the reaction with the medicine C1 is started. Medicine filling container 5
When the liquid medicine D1 flows into the space B, the liquid medicine D1 reacts with the medicine C1 and also flows into the space B below through the water permeable sheet 5a to react with the medicine B1 filled in the space B. Therefore, the cooling container according to the present invention can be placed inside the reaction container 2 by pushing the movable lid 3 toward the reaction container 2.
The endothermic reactions by the drugs of the types are initiated almost simultaneously. When an endothermic reaction occurs in the reaction container 2, the temperature of the reaction container 2 rapidly decreases, and the content A1 filled in the space A is between the side wall 20 of the reaction container 2 and the side wall 10 of the container body 1. Space a
In, the contents A1 are cooled by exchanging heat. Destruction member 7
When the sheet 6a that seals the bottom of the liquid filling container 6 is broken, the liquid drug D1 in the drug filling container 5 is transferred to the drug filling container 5
A hole may be formed in the connecting portion connecting the cutting blade 7a and the top portion 6a of the container so that the cutting blade 7a can be easily flowed into the container. It is also possible. The sheet 6a that seals the bottom of the liquid filling container 6 may be a polymer film such as a polyethylene film, or an aluminum foil or the like as long as it can be easily broken by the breaking member 7. The drug-filled container 5 may be a container whose upper portion is sealed by a member that is easy to break like the sheet 6a. The sheet 5a that seals the bottom of the drug filling container 5 is a solid or powder drug B1 and C1.
As long as the liquid medicine D1 can be prevented from mixing and the liquid medicine D1 that has flowed into the medicine filling container 5 can also flow into the space B below, the liquid medicine D1 such as a nonwoven fabric can pass through. Alternatively, it may be paper or a water-soluble film that is dissolved by the liquid drug D1. With sheet 5a
6c can be fixed by means such as adhesion, heat sealing, and side wall screwing. Note that the container body 1 may be a paper container, a composite container, or the like, in addition to a metal container such as aluminum. The movable lid 3 that seals the upper opening 1a that houses the reaction container 2 is sufficient if a sufficient stroke is obtained that allows the cutting blade 7a of the breaking member 7 to hit the sheet 6c and break. Besides the absorption lid shown in the embodiment, a bellows or the like can be used.

【effect】

As described above, since the cooling container according to the present invention is filled with the three kinds of chemicals in the completely separated space, it is possible to use the corrosive chemicals, and it can be used for a long time. It is possible to completely solve the problem with the conventional container in which the cooling agent spontaneously starts the reaction even when stored and the effect is reduced to half when used. Then, when it is desired to start cooling, the three kinds of chemicals having a large cooling effect start the reaction by a simple operation of pushing the movable lid that seals the upper opening into the reaction container. Therefore,
The cooling container is extremely easy to handle and has a great cooling effect.
