[First Embodiment]
Hereinafter, the cold insulation tool according to the first embodiment of the present invention will be described with reference to FIGS. In all the drawings below, the dimensions and ratios of the constituent elements are appropriately changed in order to make the drawings easy to see.

[Cold insulation tools]
FIG. 1 is a schematic perspective view of the cold insulation tool 1 of the present embodiment. The cold insulation tool 1 accommodates a cylindrical storage container B filled with a beverage, and is used to produce an ice slurry by controlling the supercooled state of the beverage in the storage container B.

In the present specification, the “beverage” is a soft drink containing a component that is generally called a functional beverage and has a function of regulating a biological activity, and in particular, a balance of electrolyte and carbohydrate. Refers to an aqueous beverage that takes into account This may include various vitamins, amino acids, dietary fiber, and the like. “Beverages” are so-called beverages called sports beverages, isotonic beverages, hypotonic beverages, oral rehydration solutions, balanced beverages, and the like.

For example, sodium chloride or magnesium chloride whose ion concentration is adjusted is used for the electrolyte in order to promote absorption of moisture in the body. Moreover, glucose, fructose, etc. are used for saccharides in order to replenish energy. As amino acids, branched chain amino acids and the like that are effective for maintaining muscles and recovering muscle fatigue are often used.

The “storage container” is a cylindrical container having a storage space filled with the beverage, and is mainly a plastic bottle or a can.

Such a “beverage” is completely frozen in a domestic freezer controlled at about −18 ° C. or a commercial refrigerator controlled at about −30 ° C. Therefore, it is difficult to produce an ice slurry from a beverage using these freezers.

Also, conventionally, a cold-retaining tool for keeping a drink at an appropriate temperature is intended to keep the drink in an appropriate temperature range. Therefore, it is not assumed that the beverage is cooled at a temperature below the lower limit of the appropriate temperature, for example, 0 ° C. or lower. Therefore, it is not assumed that an ice slurry is produced by controlling the supercooled state of the beverage using this type of cold insulation tool.

On the other hand, when the cold insulation tool 1 of the present embodiment is used, an ice slurry can be easily produced.

The cold insulation tool 1 has a surface area in an exterior body 10 provided so as to accommodate a storage container B for beverages, a heat exchanging portion 25 provided detachably in the exterior body 10, and at least a part of a gas-liquid interface of the beverage. And the stimulating unit 30 to be increased.

(Exterior body)
The exterior body 10 has a cylindrical shape having a bottom portion, a cylindrical shape having a bottom portion, and an opening / closing portion 11 capable of adjusting the opening diameter of the upper opening portion 10a. The opening / closing part 11 is, for example, a fastener or a button. In the cold insulation tool 1, the opening diameter of the opening 10a can be adjusted to be small while covering the entire storage container B.

Further, if the opening diameter of the opening 10a can be adjusted, a string-like member is adopted as the opening / closing part 11, and the opening 10a is narrowed by a string-like member like a so-called drawstring bag. It is good also as adjusting an opening diameter.

In the cold insulation tool 1 having such a configuration, the upper part of the exterior body 10 can be closed, so that the storage container B can be prevented from falling off and heat input through the opening 10a can be suppressed.

In the cold insulation tool 1 having the exterior body 10 as shown in the figure, the cold insulation is performed in a state in which the storage container B as a cold storage object stands in the exterior body 10 (a state in which the storage container B is supported at the bottom of the storage container B). Is done. A cold insulation tool that realizes such a cold insulation state may be hereinafter referred to as a “vertical installation type”.

Although the exterior body 10 can be manufactured using various materials, it is preferable to use foamed resin or cloth as a forming material. These materials contain an air layer inside and have high heat insulation performance. Therefore, it is possible to suppress the occurrence of condensation on the outer surface of the exterior body 10 when the cold insulation tool 1 is used.

Furthermore, it is preferable that the exterior body 10 is made of a stretchable material (stretchable material). When a stretchable material is used as the forming material of the outer package 10, even when the inner diameter of the outer package 10 is smaller than the outer diameter of the storage container B, the outer package 10 extends in the radial direction and accommodates the storage container B. can do. In such a case, the exterior body 10 can be tightened from the periphery of the storage container B and the heat exchange unit 25 housed inside the exterior body 10, and the storage container B and the heat exchange unit 25 can be brought into close contact with each other.

As the material of the outer package 10, foamed rubber which is a foamed resin having stretchability is preferable. Examples of the foamed rubber include foamed chloroprene rubber.

The size of the outer package 10 may be appropriately set according to the size of the storage container B to be kept cold and the size of the heat exchange unit 25 used for keeping cold.

The exterior body 10 may have a fixed belt (fixed part) on the upper end side of the inner peripheral surface 10x. The fixing belt winds around the storage container B and fixes the storage container B. Thereby, it is possible to cool the storage container B and the heat exchanging unit 25 in a state where they are close to or in contact with each other.

(Stimulation unit)
FIG. 2 is a schematic perspective view showing the stimulation unit 30. As illustrated in FIG. 2, the stimulation unit 30 includes a cylindrical main body 31 having an internal space, and a holding unit 34 that holds the main body 31 in the opening Ba of the storage container B.

In the cold insulation tool 1 of the present embodiment, the stimulation unit 30 is detachably provided with the central axis aligned with the opening Ba of the storage container B. The diameter of the main body 31 is smaller than the diameter of the opening Ba of the storage container B.

A plurality of holes 32 are formed in the bottom surface of the main body 31. In the drawing, the plurality of holes 32 are substantially circular or oval, but are not limited thereto. The shape of the plurality of holes 32 may be, for example, a triangle, a rectangle, a star, an ellipse, or a part of these structures deformed.

The plurality of holes 32 are arranged radially from the center of the bottom surface of the main body 31, but are not limited thereto. The arrangement method of the plurality of holes 32 may be, for example, a staggered pattern.

A plurality of holes 33 are formed on the outer peripheral surface of the main body 31. In the drawing, the plurality of holes 33 have a rectangular shape, but are not limited thereto. The shape of the plurality of holes 32 may be, for example, the shape described above.

Further, the plurality of holes 33 are arranged along the height direction of the main body 31 and the circumferential direction of the central axis, and the outer peripheral surface of the main body 31 has a lattice shape as a whole. The arrangement | positioning method of the some hole 32 is not limited above, For example, a zigzag form may be sufficient.

The number of the plurality of holes 32 and the plurality of holes 33 is not particularly limited. Further, as long as the main body portion 31 has a plurality of holes 32 on the bottom surface, the main body portion 31 may not have the plurality of holes 33.

The material for forming the main body 31 is not particularly limited. However, since the plurality of holes 32 and the plurality of holes 33 are easily formed, polyethylene, polypropylene, polystyrene, or polyester, acrylonitrile-styrene copolymer (hereinafter referred to as AS resin). Etc. are preferable.

The holding part 34 is provided on the circumference of the upper surface of the main body part 31. The diameter of the holding part 34 is larger than the diameter of the opening Ba of the storage container B.

(Heat exchange part)
FIG. 3 is a schematic perspective view showing the heat exchange unit 25. FIG. 4 is a cross-sectional view taken along line IV-IV in FIG.

3 and 4, the heat exchange unit 25 includes a heat storage material 21 having a predetermined melting point and a filling unit 26 having an internal space for filling the heat storage material 21 in a liquid-tight manner.

In the cold insulation tool 1 of the present embodiment, the heat exchange unit 25 is provided along the outer peripheral surface Ba of the storage container B and at a position in contact with at least a part of the outer peripheral surface Ba in the circumferential direction. More specifically, the heat exchange unit 25 is disposed along the inner peripheral surface 10 x of the exterior body 10.

The heat exchanging part 25 “contacts with the outer peripheral surface Ba” means that when the storage container B is stood in a normal posture with the bottom surface facing downward, the portion filled with the beverage in the radial field of view of the storage container B It means that the outer peripheral surface of the overlapping storage container B is in contact with the heat exchange unit 25.

More specifically, the “outer peripheral surface” where the storage container B and the heat exchange unit 25 are in contact refers to an outer peripheral surface in a range where the outer peripheral diameter is constant in a cross section orthogonal to the central axis of the storage container B. Such an outer peripheral surface is a surface in a range from the bottom surface of the storage container B to a predetermined height.

For example, when the storage container B is a standard size PET bottle containing 500 ml and the body is a straight type, the outer peripheral surface is generally about 140 mm to 150 mm in height from the bottom surface of the storage container B until the outer peripheral diameter starts to gradually decrease. This refers to the cylindrical region.

In addition, when the storage container B is a standard-sized straight can containing 500 ml, the outer peripheral surface indicates almost the entire range of 167.7 mm in height defined by JISZ1571: 2005 (metal can for food).

Further, “part” of “contacts at least a part of the outer circumferential surface Ba in the circumferential direction” means that the heat exchange unit 25 is in contact with the outer circumferential surface Ba and the filling portion 26 in the circumferential direction of the outer circumferential surface Ba. It means that the central angle of the arc from one end to the other is less than 360 °. In the cold insulation tool 1 of the present embodiment, the central angle of the arc from one end to the other end of the filling portion 26 is in contact with 360 °, that is, the entire circumferential direction Ba (entire circumference). In the present embodiment, the central angle may be adjusted according to the set time for cooling the beverage to be kept cold to the slurry generation standby state (supercooled state).

(Heat storage material)
The melting point of the heat storage material 21 is less than −0.2 ° C. This is because the beverages that are to be kept cold are aqueous beverages containing substances such as electrolytes and sugars, and it is easily guessed that the primary crystal point will be −0.2 ° C. or less depending on the concentration of the substances contained. Because. The melting point of the heat storage material 21 to be used may be appropriately adjusted according to the composition of the beverage to be kept cold. The melting point of the heat storage material 21 is more preferably −3 ° C. or less. On the other hand, the melting point of the heat storage material 21 may exceed −30 ° C. The melting point of the heat storage material 21 is higher than −30 ° C. and lower than −0.2 ° C., preferably higher than −18 ° C. and lower than −0.2 ° C., more preferably −11 ° C. or higher and −3 ° C. or lower.

In addition, the freezing temperature of the heat storage material 21 is preferably −30 ° C. or higher, more preferably −18 ° C. or higher.

It can be confirmed by the following method that the freezing temperature of the heat storage material 21 is −30 ° C. or higher. First, 40 g of the heat storage material 21 is put in a plastic container and left to stand for 10 hours in a thermostatic chamber (manufactured by ESPEC, SU-242) set at −30 ° C. After 10 hours, the plastic container is taken out of the thermostatic bath, and it is confirmed whether or not the heat storage material 21 is frozen. If the heat storage material 21 is frozen, it means that the freezing temperature of the heat storage material 21 is −30 ° C. or higher. If the temperature of the thermostatic chamber is set to −18 ° C., it can be confirmed that the freezing temperature of the heat storage material 21 is −18 ° C. or higher by the same method as described above.

The heat storage material 21 is preferably an inorganic salt aqueous solution containing water and an inorganic salt.

The inorganic salt is a water-soluble salt and is an ionic compound that ionizes into a cation and an anion when dissolved in water. The inorganic salt is a salt that exhibits a freezing point depression when the concentration of the inorganic salt in the inorganic salt aqueous solution is less than the concentration that provides a eutectic of water and the inorganic salt. The “inorganic salt content concentration in the inorganic salt aqueous solution” is the inorganic salt content concentration relative to the total mass of the inorganic salt aqueous solution.

Specific examples include chloride salts such as sodium chloride, potassium chloride, and ammonium chloride, bromide salts, nitrates such as potassium nitrate, sulfates such as magnesium sulfate, phosphates, and carbonates.

As one aspect, the concentration of the inorganic salt relative to the total mass of the inorganic salt aqueous solution is preferably a concentration that gives a eutectic of the water and the inorganic salt.

For example, when potassium nitrate is used as the inorganic salt, when the concentration of the inorganic salt in the inorganic salt aqueous solution is about 10% by mass, a eutectic crystal of water and potassium nitrate is given, and a heat storage material having a melting point of about −3 ° C. is obtained. It is done.

When magnesium sulfate is used as the inorganic salt, when the concentration of the inorganic salt in the inorganic salt aqueous solution is about 19% by mass, a eutectic of water and magnesium sulfate is given, and a heat storage material having a melting point of about −4 ° C. is obtained. It is done.

When potassium chloride is used as the inorganic salt, when the concentration of the inorganic salt in the inorganic salt aqueous solution is about 20% by mass, a eutectic crystal of water and potassium chloride is given, and a heat storage material having a melting point of about −11 ° C. is obtained. It is done.

When ammonium chloride is used as the inorganic salt, when the concentration of the inorganic salt in the inorganic salt aqueous solution is about 18% by mass, a eutectic of water and ammonium chloride is given, and a heat storage material having a melting point of about −15 ° C. is obtained. It is done.

When sodium chloride is used as the inorganic salt, when the concentration of the inorganic salt in the inorganic salt aqueous solution is about 23% by mass, a eutectic of water and sodium chloride is given, and a heat storage material having a melting point at about -21 ° C. is obtained. It is done.

In the heat storage material 21, one type of inorganic salt may be used alone, or two or more types may be used in combination. Adjustment of the melting point of the heat storage material 21 is facilitated by using two or more inorganic salts in combination.

As one aspect, the content concentration w of the inorganic salt relative to the total mass of the aqueous inorganic salt solution may be less than the concentration that gives a eutectic of water and the inorganic salt. In this case, the melting point T of the heat storage material preferably satisfies the following formula (1). The right side of the following formula (1) is a formula indicating a general freezing point depression degree (unit: K), but in the present application, when an inorganic salt is added to water at a concentration lower than the eutectic concentration, the melting point T ( It was found that it can be used as a unit: ° C.

(T: melting point (° C.)
w: Concentration of inorganic salt (% by mass)
M: Molecular weight of inorganic salt (g / mol)
R: Gas constant (J / K · mol)
Tf: melting point of water (K)
ΔH: latent heat of water (J / g)
n: number of ions generated when one inorganic salt is ionized in an aqueous solution)

In addition, as mentioned above, n in the above formula (1) is the number of ions generated when one inorganic salt is ionized in an aqueous solution. When the inorganic salt is sodium chloride, ions generated upon ionization are a sodium cation and a chloride anion, and n is 2.

In addition, as the heat storage material 21, polyethylene glycol, paraffins, higher alcohols, and organic clathrate hydrates can be used as long as a desired melting point can be realized.

The heat storage material 21 may contain an organic solvent as long as the effects of the invention are not impaired.

The heat storage material 21 is preferably added with a preservative or an antibacterial agent.

The heat storage material 21 may be added with a thickener such as xanthan gum, guar gum, carboxymethyl cellulose, or sodium polyacrylate. As the thickener, it is preferable to select a material having a salt resistance property.

The heat storage material 21 may be dyed by dissolving a dye. It becomes easy to notice the leakage of the heat storage material 21 because the heat storage material 21 is dyed. As the dye, a conventionally known dye can be used as long as the effects of the invention are not impaired.

The heat storage material 21 as described above can adjust the melting point by adjusting the type and concentration of the inorganic salt.

In the present specification, a value obtained by differential scanning calorimetry (DSC) is adopted as the melting point of the heat storage material 21. Specifically, first, about 4 mg of a heat storage material in a liquid phase state is sealed in an aluminum pan for DSC measurement, the temperature is lowered at a rate of 5 ° C./min, and the phase is changed from a liquid phase state to a solid phase state. The temperature is raised at a rate of ° C / min. At this time, when the phase changes from the solid phase to the liquid phase, an endothermic peak is obtained in the DSC curve. The temperature obtained by extrapolating the temperature at which the endothermic peak begins to the baseline is taken as the melting start temperature. The obtained melting start temperature was determined as the melting point of the heat storage material.

(Filling part, connecting part)
The heat exchange unit 25 includes a plurality of filling units 26. Each of the plurality of filling portions 26 extends in one direction.

It is preferable that the plurality of filling portions 26 are disposed along the inner peripheral surface 10x and in the entire circumferential direction of the inner peripheral surface 10x (the entire circumference).

The part closely adhered to the band functions as the connecting part 23. In addition, each of the spaces defined by the connecting portion 23 in the bag member 261 functions as the filling portion 26.

In such a heat exchanging unit 25, the plurality of filling units 26 are integrally formed.

In FIG. 4, the cross-sectional shape of the filling portion 26 is an ellipse, but may be other shapes.

The forming material of the bag member 261 is preferably, for example, polyethylene, polypropylene, polyamide, or polyethylene terephthalate. Moreover, as a forming material of the bag member 261, for example, polyvinyl alcohol, polyvinyl chloride, or polyvinylidene chloride may be used.
