Description

[Technical Field]

[0001] The present invention relates to a water-based portable coolant. [Background technology]

[0002] Conventionally, ice packs that are not too cold to be uncomfortable even when frozen are known (see, for example, Patent Document 1). Also, conventionally, cooling materials that include a bag for storing a cryogen and a bag for storing water to be mixed with the cryogen (hereinafter also referred to as a water bag) are known. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-118059 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the ice pack described in Patent Document 1 had to be cooled before use. Also, when a user carried an ice pack with them when going out, the cooled ice pack sometimes warmed up during transportation, making it impossible to use as an ice pack.

[0005] In addition, to use the above-mentioned coolant, the user must locate the water bag, impact the water bag to break it, and then mix it with the cryogen to cool the coolant. Therefore, if the user is a child, they may not be able to impact the water bag, and the water bag inside the coolant may not break, making it unusable as a coolant. Furthermore, because the above-mentioned coolant includes a water bag, it has a certain weight and is not suitable for carrying around as a coolant. Therefore, there is currently room for improvement in providing a coolant that is portable and properly cooled.

[0006] Therefore, an object of the present invention is to provide a portable cooling material that can be properly cooled when used by a user. [Means for solving the problem]

[0007] One aspect of the present invention is a water-supply type portable cooling material that includes a water-soluble first bag containing a first material consisting of a first component, a water-soluble second bag containing a second material consisting of a second component that absorbs heat when reacting with the first component, and a water-insoluble bag that can simultaneously contain the first and second bags and has a supply port formed therein for supplying liquid from the outside. [Effects of the Invention]

[0008] According to the present invention, a portable cooling material can be provided that is appropriately cooled when the user uses the cooling material. [Brief explanation of the drawings]

[0009] [Figure 1] 1 is a diagram showing an example of a water-supply type portable cooling material according to the present embodiment. [Figure 2] FIG. 10 is a diagram showing a state in which liquid is supplied to the water-supply type portable cooling material according to the present embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0010] An embodiment of a water-supply type portable coolant 1 according to the present invention will be described with reference to the accompanying drawings. In each drawing, the same reference numerals denote the same or similar configurations. However, the present invention is not limited to the embodiment.

[0011] The water-supply type portable cooling material 1 can be carried by the user, for example, by storing it in a suitcase, bag, luggage, etc. Furthermore, the size (e.g., regular size, mini size, etc.) and shape of the water-supply type portable cooling material 1 are not particularly limited and can be designed as desired.

[0012] Users can use the water-supply type portable coolant 1 as a coolant by supplying liquid (e.g., water) to it in various situations, such as when they are sick (e.g., fever, sprains, fractures, burns, etc.), preparing for disasters (e.g., earthquakes, power outages), preventing heatstroke (e.g., sports days, etc.), and icing (e.g., when fishing, cooling drinks).

[0013] Fig. 1 is a diagram showing an example of a water-supply type portable coolant 1 according to this embodiment. The water-supply type portable coolant 1 shown in Fig. 1 shows an example of the state of the water-supply type portable coolant 1 before liquid is supplied to the water-supply type portable coolant 1.

[0014] The water-supply type portable coolant 1 comprises a water-soluble first bag 10, a water-soluble second bag 20, and a water-insoluble bag 30 that can simultaneously accommodate the first bag 10 and the second bag 20 and has a supply port 40 formed therein for supplying liquid from the outside.

[0015] The first bag 10 contains a first material 11 made of a first component, and the second bag 20 contains a second material 21 made of a second component that absorbs heat when reacting with the first component.

[0016] By storing the first material 11 and the second material 21 in separate bags (the first bag 10 and the second bag 20), the water-supply type portable cooling material 1 can prevent either material from deliquescing and the first material 11 and the second material 21 from coming into contact with each other, thereby accelerating the deliquescence.

[0017] The supply port 40 may be provided at the top of the water-supply-type portable coolant 1. A handle 41 may be provided to support the supply of liquid to the supply port 40. The handle 41 is configured to surround the supply port 40, and may be provided independently on the front and back surfaces of the water-insoluble bag 30. The handle 41 may also be printed with any desired text (for example, "supply port"). This allows the user to easily identify the location of the supply port 40.

[0018] The user can open the supply port 40 by grasping the handles 41 provided independently on the front and back surfaces and spreading the handles 41 to the left and right. The user can easily supply liquid from the opened supply port 40. Note that at least one of the front and back surfaces of the water-supply-type portable cooling material 1 may be printed with any desired design.

[0019] Fig. 2 is a diagram showing a state in which liquid has been supplied to the water-supply type portable coolant 1 according to this embodiment. As shown in Fig. 2, a user can supply liquid to the water-supply type portable coolant 1 from the supply port 40, thereby dissolving the first bag 10 and the second bag 20 and causing the first component, the second component, and the liquid to react with each other. Furthermore, a mixed liquid 50 is generated by mixing the first component, the second component, and the liquid.

[0020] With the above configuration, when liquid is supplied from the supply port 40 to the water-supply type portable coolant 1, the first bag 10 and the second bag 20 melt. Then, the first material 11 and the second material 21 contained in the first bag 10 and the second bag 20 react with the liquid, causing an endothermic reaction. As the endothermic reaction occurs, the temperature inside the water-insoluble bag 30 may drop to -10°C or below, for example, and the water-supply type portable coolant 1 may be appropriately cooled.

[0021] As a result, the user can use the appropriately cooled water-supply-type portable coolant 1 by supplying liquid from the supply port 40 at any place and at any time.

[0022] Furthermore, because the portable water-supply cooling element 1 according to this embodiment does not have a water bag and is lightweight, a user can store the portable water-supply cooling element 1 in, for example, a bag, go outdoors in the hot sun, and when they want to cool down, supply liquid to the portable water-supply cooling element 1, thereby using the cooled portable water-supply cooling element 1. Furthermore, because it is possible to easily transport a large number of portable water-supply cooling elements 1 to disaster areas, it is possible to use a large number of portable water-supply cooling elements 1 for the many disaster victims suffering from the heat, etc., in evacuation shelters that are not adequately equipped with air conditioning.

[0023] In addition, since the water-supply type portable coolant 1 does not have a bag for storing water, it is easy to secure space for storing the water-supply type portable coolant 1. As a result, a large number of water-supply type portable coolants 1 can be appropriately stored in evacuation sites and the like in preparation for disasters.

[0024] Furthermore, for example, when a user goes fishing and stores the fish they catch in a container such as a cooler box, they can supply liquid (e.g., river water) to the water-supply type portable coolant 1 and use it as a coolant, thereby making it possible to store the fish they catch in the cooler box or the like in an appropriately cooled environment.

[0025] Furthermore, the user can repeatedly use the water-supply type portable coolant 1 by cooling the liquid-supplied portable coolant 1 in a freezer or refrigerator. An example of the water-supply type portable coolant 1 will be described in detail below.

[0026] The first bag 10 may be a bag containing a first material 11 including, for example, at least one of ammonium nitrate and urea as a first component. The first material 11 may also include at least one of ammonium chloride, sodium nitrite, and ammonium thiacyanate.

[0027] The second bag 20 may be a bag containing a second material 21 containing, for example, at least one of ammonium nitrate and urea as a second component. The second material 21 may also contain at least one of ammonium chloride, sodium nitrite, and ammonium thiacyanate.

[0028] Furthermore, the first material 11 and the second material 21 may be different materials. At least one of the first material 11 and the second material 21 may be in a powder state. At least one of the first material 11 and the second material 21 is not limited to the above-mentioned materials and may be other materials (e.g., other cryogens).

[0029] The first bag 10 and the second bag 20 may be bags made of a PVA (Polyvinyl Alchol) film. The first bag 10 and the second bag 20 made of a PVA film can prevent water vapor in the air from passing through the first material 11 and the second material 21.

[0030] Furthermore, since the first bag 10 and the second bag 20 manufactured using PVA film are water-soluble, the first bag 10 and the second bag 20 react with the supplied liquid, thereby dissolving the first bag 10 and the second bag 20 in the liquid in a short period of time.

[0031] Furthermore, the amount of heat absorbed by mixing the first component, the second component, and the liquid may be greater than the amount of heat absorbed by mixing the first component and the liquid, and may also be greater than the amount of heat absorbed by mixing the second component and the liquid.

[0032] In this way, the liquid, the first component of the first material 11, and the second component of the second material 21 react and mix appropriately, so that the amount of heat can be absorbed appropriately.

[0033] The supply port 40 of the water-insoluble bag 30 may be provided with a check valve. By employing a check valve in the supply port 40, it is possible to prevent the liquid in the water-supply-type portable coolant 1 from leaking from the supply port 40 even when the supply port 40 is perpendicular to the ground. There is no particular limitation on where the supply port is provided. Instead of employing a check valve in the supply port 40, a pouch or a cap may be provided on the water-supply-type portable coolant 1.

[0034] A gelling agent may be mixed into at least one of the first material 11 and the second material 21. For example, the water-supply-type portable cooling material 1 may have CMC (Carboxy Methyl Cellulose) mixed as a gelling agent into at least one of the first material 11 and the second material 21. The gelling agent is not limited to the above-mentioned materials, and may be other materials (e.g., other gelling agents such as xanthan gum and guar gum).

[0035] By mixing a gelling agent into at least one of the first material 11 and the second material 21, the mixed liquid 50 produced when the liquid is supplied from the supply port 40 gradually becomes a viscous liquid, and the mixed liquid 50 can be transformed into a gel state. As a result, a gel-like coolant can be produced that will not freeze even when frozen in a freezer. Furthermore, the water-supply-type portable coolant 1 that has become a gel-like coolant can be reused.

[0036] Furthermore, the viscosity of the mixed liquid 50 can be increased by the user rubbing the gel-like mixed liquid 50, and the mixed liquid 50 can be used as a soft and comfortable coolant. Furthermore, since the mixed liquid 50 is in a gel-like state, even if the mixed liquid 50 leaks from a freezer or the like, damage (such as spillage on other items stored in the freezer or the like) can be reduced compared to when the mixed liquid 50 is in an aqueous solution state.

[0037] The above-described embodiments are intended to facilitate understanding of the present invention and are not intended to limit the scope of the present invention. The elements of the embodiments, as well as their arrangement, materials, conditions, shapes, sizes, etc., are not limited to those shown in the examples and can be modified as appropriate. Furthermore, the configurations shown in different embodiments can be partially substituted or combined with each other. [Explanation of symbols]
