Description

[Detailed explanation of the invention] "Industrial application field" This invention can be used outdoors in the hot summer.
This invention relates to a temperature-controllable cool tissue that can easily provide a cool feeling that makes you feel comfortable.

"Prior Art and its Problems" When outdoors in the heat of the summer, there is a great need for something that can provide a cooling sensation, such as a cold wringer, when sweating.

However, at present, the only way to obtain cold squeezes outdoors is to store and cool the squeezer impregnated with water in an insulated container such as a cool box, and then take it out and use it when needed. The problem was that it was inconvenient.

In addition, wet tissues are known as a method that can easily provide a cooling sensation in place of squeezing. This wet tissue is made by sealing a non-woven fabric impregnated with ethyl alcohol in a non-breathable bag. When the bag is opened and the non-woven fabric is taken out during use, the ethyl alcohol evaporates and the heat of evaporation is taken away, causing the non-woven fabric to is cooled and gives a cooling sensation.

However, with this kind of wet tissue, there is a limit to the amount of ethyl alcohol that can be impregnated, and the amount of evaporation is also small, so it is not possible to obtain a sufficient cooling sensation, making it difficult to use in the summer. It was still insufficient for use when sweating.

Recently, a quick-cooling type wet tissue has been released that contains a wet tissue, a coolant, and a water bag in a bag. However, once the endothermic agent and water are mixed and the chemical reaction begins, it is impossible to control the temperature, so it is not possible to set the temperature to a temperature that is comfortable for the user, which left some dissatisfaction.

This idea was made in view of the above circumstances,
The purpose is to provide a temperature-controllable cool tissue that is easily portable, can be used when necessary, and provides a cooling sensation that is comfortable to the user.

``Means for solving the problem'' The temperature-controllable cool tissue of this invention consists of an air cap-like sheet made up of a large number of water bags each filled with a small amount of independent water.
It is composed of an endothermic agent that reacts with water to cause an endothermic reaction, water-insoluble paper impregnated with liquid, and an outer bag that has a storage chamber inside that is watertightly partitioned by a partition made of a water-impermeable sheet. The above problem was solved by storing the air cap-shaped sheet and the heat absorbing agent in a storage chamber, and placing water-insoluble paper outside the storage chamber and sealing it in an outer bag.

``Function'' According to the temperature-controllable cool tissue of this invention, when in use, the outer bag is pressed to burst some of the water bags on the air cap-like sheet inside the inner bag, and the appropriate amount of water is released. By reacting water with an endothermic agent, water-insoluble paper can be cooled to the desired temperature.

"Embodiment" FIGS. 1 and 2 are diagrams showing an embodiment of this invention, in which reference numeral 1 denotes a disposable temperature-controllable cool tissue (hereinafter referred to as
(abbreviated as "Courteitshu"). This cool tissue 1 includes an outer bag 2, an air cap-shaped sheet 3 made up of a large number of water bags filled with a small amount of independent water sealed in the outer bag 2, a heat absorbing agent 4, and a wet bag. It is roughly constructed from a container 5.

The outer bag 2 is a rectangular bag made of aluminum foil or the like.
Notches 6, 6 on both sides to facilitate opening
The inside of the notches 6, 6 is sealed to airtightly seal the inside of the bag. Also, this outer bag 2
Inside, there are a pair of partition walls 7, as shown in FIG.
A storage chamber 8 is provided inside these partition walls 7, 7 in a bag-like manner, the inside of which is sealed watertight. Here, the partition walls 7, 7 are made of aluminum foil or a sheet obtained by laminating aluminum on a polyethylene sheet, and are not only water-impermeable but also highly thermally conductive.

The sheet 3 is stored in the storage chamber 8 and is made of a bag made of polyethylene or the like and filled with water. Further, the sheet 3 is relatively easily ruptured by pressure, allowing the water inside to flow out into the storage chamber 8.

The endothermic agent 4 is stored in the storage chamber 8 together with the water bag 3, and is a granular material made of a drug such as ammonium nitrate that reacts with water to cause an endothermic reaction.

The wet tissue 5 is disposed inside the outer bag 2 and outside the partition walls 7, 7 constituting the storage chamber 8, and is made of non-water-soluble paper (for example, non-woven fabric) impregnated with water, ethyl alcohol, and fragrance. It consists of In addition, this wet tissue 5 is
It is folded at the position indicated by the broken line in FIG. 3 and stored in the outer bag 2 in a folded state.

In order to use the cool tissue 1 having such a configuration, first, the outer bag 2 is pressed from the outside to burst the desired number of water bags on the seat 3 in the storage chamber 8. Then, in the storage chamber 8, the desired amount of water flowing out from the sheet 3 and the endothermic agent 4 undergo an endothermic reaction,
The partition walls 7, 7 are cooled by removing heat from the surroundings, and the wet tissue 5 is also cooled via these partition walls 7, 7. In this case, since the partition walls 7, 7 are made of aluminum foil or the like with high thermal conductivity, the wet tissue 5 disposed adjacent to the partition walls 7, 7 can absorb heat to provide the desired cooling sensation. Also, since the wet tissue 5 is impregnated with water or ethyl alcohol, which has a large heat capacity and a high degree of cold retention, the wet tissue 5 quickly reaches the desired temperature and has the ability to maintain its cooling state sufficiently. Become what you have.

Next, after the reaction between the water and the endothermic agent 4 has sufficiently progressed and the wet tissue 5 has been cooled to the desired temperature (usually it takes about 3 minutes to cool down), the wet tissue 5 is heated from an appropriate position in the notch 6. The outer bag 2 is opened and the wet tissue 5 is taken out and used.

With the cool tissue 1 having such a configuration, it is possible to obtain the wet tissue 5 having the desired degree of cooling by a simple operation such as pressing the outer bag 2, so that it can be used outdoors in the summer. You can easily and instantly obtain a cooling sensation that suits your taste. In addition, since it is small and lightweight, it is easy to carry, and since it is disposable, it eliminates the hassle of transporting it.

Note that in the above embodiment, the pair of partition walls 7,
7 is made into a bag shape to form a storage chamber 8, but another bag made of the same material as the partition wall 7 is prepared and placed inside the outer bag 2 to serve as an inner bag, and the inside thereof is used as a storage chamber and the The wet tissue 5 may be placed on the outside.

(Prototype Example) A cool tissue 1 having the configuration shown in FIGS. 1 to 3 was manufactured.

The outer bag 2 was made from aluminum foil with a thickness of 0.01 mm, and the length of the outer bag 2, indicated by _L1 in FIG. 1, was 14 cm, and the width, indicated by _L2, was 8 cm. Further, the partition walls 7, 7 constituting the storage chamber 8 were also formed from the same aluminum foil. The air cap-shaped sheet bag 3, which is a collection of many water bags each filled with a small amount of water, was made of polyethylene, and the amount of water filled in each bag was 0.5 cc, and the total amount of water was 6 cc. . As the heat absorbing agent 4, a spherical material with a particle size of about 1 mm, which is mainly composed of ammonium nitrate and added with a binder, etc., is used.
I stored about 40g of this. For the wet tissue 5, prepare four sheets of nonwoven fabric with a thickness of 0.3 mm impregnated with appropriate amounts of water, ethyl alcohol, and fragrance, and each of them has a length of 20 cm, indicated by L ₄ in Figure 3, and a width of 20 cm, indicated by L ₅ .
15 cm, folded at the position shown by the broken line in FIG. 3, and stored two sheets on each side of the storage chamber 8 in the outer bag 2. After storing the sheet 3, heat absorbing agent 4, wet tissue 5, etc. in the outer bag 2 in this way, the inside of the outer bag 2 is airtightly sealed with a seal width of 1 cm each as indicated by L ₃ in Fig. 1. And got 1 Cool Teishu.

The cool tissue 1 thus produced was tested at an environmental temperature of approximately 30°C, and the relationship between the elapsed time after all the water bags on the sheet 3 were ruptured and the temperature of the wet tissue 5 was investigated. As a result, the results shown in FIG. 4 were obtained.

From FIG. 4, after about 1 minute has passed, the wet tissue 5 on the inside (storage chamber 8 side) has increased by about 2 to 30 minutes.
When the temperature reaches 3°C and after about 3 minutes, the wet tissue 5 on the outside (outer bag 2 side) becomes about 2~3°C.
It was confirmed that the temperature was cooled to ℃.

``Effects of the invention'' As explained above, when using the temperature-controllable cool tissue of this invention, the outer bag is pressed to burst the water bladder on the sheet inside the inner bag as per the user's preference. By reacting a certain amount of water with an endothermic agent, water-insoluble paper can be cooled to the desired temperature, so even outdoors in the summer, it can easily and instantly change from a high cooling sensation to a slightly cold sensation. You can choose from a wide range of cooling sensations and enjoy a refreshing feeling.
