Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is intended to reduce pain and inflammation due to sudden fever, headache, toothache, sprains, bruises, etc. and minute damage to muscles due to intense exercise, prevent heat stroke, reduce heat during sports and outdoor work, Wrap around the neck, arms, legs, head, chest, etc. to cool the affected area or muscles, or to eat or drink, fresh food, medicines, chemicals, etc. The present invention relates to a cooling device that is directly wound around a cooling device and cools, and that can obtain an excellent cooling effect.

[0002]

[Prior art]

 Conventional cooling devices have been used in close contact with the affected area or muscle with a belt or the like, fixed on the forehead with an adhesive, or put in a pocket. In addition, when cooling food and drink, fresh foods, pharmaceuticals, chemicals, etc., it was necessary to use them in a heat insulation box.

[0003]

[Problems to be solved by the invention]

 The conventional cold storage device had the drawback that when it was brought into close contact with the affected area or muscle with a belt or the like, the length of the belt did not match or it shifted due to movement of the body, making it impossible to cool the target part. . In the case of a cooler that is fixed to a forehead or the like with an adhesive, there was a drawback that the adhesive peeled off due to sweat or the like. In the case of a cooler used in a pocket, the cooling effect was very low because it did not adhere to the body. In addition, when cooling food and beverages, fresh foods, pharmaceuticals, chemicals, etc., it is necessary to put them in a heat insulation box and cool the entire heat insulation box for use. Was something.

[0004] The present invention can be easily attached to places with different thicknesses or irregularities, such as the neck, arms, legs, head, and chest of the body, and can be displaced or fall off even when the body is moved. The purpose of the present invention is to ensure that an excellent cooling effect can be obtained without using any of them, and furthermore, it is possible to cool foods, drinks, fresh foods, pharmaceuticals, chemicals, etc. without requiring a heat insulation box.

[0005]

[Means for Solving the Problems]

 According to the present invention, a bag made of a cold-resistant film material and a cold storage material mainly containing a hydrophilic gel or a water-soluble gel are filled into the bag, and the bag is filled inside or outside the bag. Cooler with a shape-retaining component to hold the shape of the body, wrapped directly around the neck, arms, legs, head, chest, etc., so there is no risk of slipping or falling off even during exercise. Can be obtained. Thick blood vessels pass through the neck, upper arm, armpits, thighs, etc. If this part can be cooled efficiently, the elevated body temperature can be reduced efficiently. In the present invention, the cooling device is always in contact with the target portion because it is wrapped around the target portion, so that an excellent cooling effect can be obtained in a short time.

Further, the neck is one of the most efficient places to cool the body without hampering the movement of the body when exercising, going out, working outdoors, and the like. In order to wind the bag around the neck, the outer length of the bag needs to be at least four times the height. Although there are individual differences in the length and thickness of the neck, as shown in Fig. 3, the part from the base of the side neck rising from the upper shoulder to the point where it hits the lower jaw is the height of the neck. The neck length and circumference of 100 men and women including the above children were measured. The result is shown in FIG. 1, and the result of calculating the ratio of the circumference to the neck length is shown in FIG. From this measurement result, it has been found that as the length of the neck increases, the circumference of the neck also tends to increase, but the circumference of the neck is at least 4 times and less than 8 times the length of the neck. In this measurement, children 7 years and older have the same tendency as adults. This is considered to be because 90% of the human brain is completed by the age of 6-7, and the neck that supports it is also showing almost the same tendency as adults.

[0007] Based on the measurement results, as a shape based on ergonomics, the height of the outer shape of the bag is not more than the length of the neck, and the outer length of the bag is not less than four times the height. By doing so, they found that they could be wrapped around the neck without disturbing the movement of the body such as the head and shoulders. This is a length that a person with a narrow neck can make about one round, but a person with a thick neck can wrap more than half a round of the neck because the ratio of the circumference to the neck length is less than eight times. It is a shape that can be applied to almost everyone because it does not fall off. If the outer length of the bag is made longer than four times the height, the bag can be wound twice or three times, and the cooling effect can be improved. The height of the outer shape of the bag can be shorter than the neck length if desired, but the cooling effect is reduced. The longer the thickness of the outer shape of the bag, the longer the cool-keeping time.

[0008] Furthermore, since the cooler so far has been a flat bag, even if it tries to adhere to curved parts such as the neck, arms, legs, head, and chest, it may wrinkle or bend. A sufficient cooling effect was not obtained. The cooler of the present invention is designed such that the length of the surface of the cooler that contacts the part to be cooled, such as the neck, arm, foot, head, chest, etc., is shorter than the length of the opposite surface. In addition, the shape of the cooler can be curved so that the cooler is in close contact with a portion to be cooled without a gap, and an excellent cooling effect can be obtained.

The shape-retaining component is a metal, resin, shape-memory alloy, or a strip-shaped, wire-shaped, rod-shaped, or tubular-shaped body made of a shape-memory resin. Those that can be deformed into shapes, or those that have shapes that match the shape of the neck, arms, legs, head, chest, etc. in advance but can be attached or detached by bending can be used. In addition to the cold storage material containing a hydrophilic gel or a water-soluble gel as a main component, a cold storage material includes a cold agent containing a cold agent containing an electrolyte that causes an endothermic reaction upon contact with the liquid agent; By using a gelling agent that absorbs and gels with a mixed electrolyte of cryogen and cold storage material, it is possible to use a cold storage material that has an instantaneous cooling function and a sustained cooling function. Such a cold storage material having an instantaneous cooling function and a sustained cooling function is disclosed in Japanese Patent Application Laid-Open No. Hei 8-280731.

[Embodiment of the invention]

 An embodiment of the invention will be described based on an example with reference to the drawings.

[0011]

Embodiment 1 FIGS. 4, 5, and 6 show one embodiment of the present invention. The outer length L of the bag of the cooler A is four times the height H. The cooler A has a cold storage material 3 sealed in a bag 1 made of a cold-resistant film material, and a shape holding component 2 is formed on the outer surface of the bag 1. For the bag 1, a 200 μm polyolefin film was used. The material of the bag 1 is not particularly limited as long as the material is non-permeable and does not break due to impact or friction. For example, polyvinyl chloride, polyethylene, polyurethane, polypropylene, or a laminate thereof is used. Can do things. As the cold storage material 3, a gel material made of polyvinyl alcohol was used. In addition to polyvinyl alcohol, those having a hydrophilic gel or a water-soluble gel as a main component can be used, and those having good gel stability, low water separation, and high flexibility are preferable. A gel-like substance formed using glycol, a gelling agent containing a crosslinking agent, water, or the like can be used. As the shape holding part 2, an aluminum rod having a diameter of 5 mm was used. Other than aluminum, other metal, resin, shape memory alloy, or strips, wires, rods, and tubes made of shape memory resin can be bent to the desired shape by hand. Things can be used. Fig. 7 is a view when the cooler of the present invention is attached to the neck. In this way, it was possible to tightly wrap around the neck just by bending it by hand, and it did not slip off or fall off even after intense exercise, resulting in an excellent cooling effect.

Example 2 The height H of the outer shape of the bag body of the cooler A is set to about 1/3 of the neck length, that is, 2.5 cm, and the outer length L of the bag body is 24 times the height H. A cold insulator was prepared in the same manner as in Example 1 except that the length was set to 60 cm. The cooler of this example could be wound about twice with a person with a thin neck and at least once with a person with a thick neck. In addition to the neck, it can be wound around the head as shown in FIG. 8, wound around the upper arm as shown in FIG. 9, or wound around two or three thighs as shown in FIG. Even in such a case, it could be wound tightly along the shape of the head and arms, and did not slip off or fall off even after intense exercise, and an excellent cooling effect was obtained. It has been confirmed that the cooling effect is improved by further increasing the number of times of winding by increasing the outer length L of the bag, or by increasing the thickness T of the outer shape of the bag, or by performing both.

Example 3 The height H of the outer shape of the bag body of the cooler A is set to about の of the neck length, that is, 2.5 cm, and the outer length L of the bag body is 15 times the height H. A cold insulator was prepared in the same manner as in Example 1 except that a bent steel strip was used as the shape maintaining component 2. A steel strip was formed in advance according to the shape of the neck or the head, etc., and as shown in FIG. Excellent adhesion was obtained, and it did not slip off or fall off even after intense exercise, and an excellent cooling effect was obtained.

Example 4 Instead of a cold storage material containing a hydrophilic gel or a water-soluble gel as a main component, a liquid agent, a cryogen containing an electrolyte that causes an endothermic reaction upon contact with the liquid agent, and the liquid agent and the cryogen A cooler was prepared in the same manner as in Example 1, except that a gelling agent that absorbed the mixed electrolytic solution and gelled was used. This cold storage material has an instantaneous cooling function and a sustained cooling function, and can be used repeatedly. The liquid medicine is filled in the easily breakable bag previously stored in the bag of the cooling device, and when the pressure is applied from the outside during use, the easily breakable bag is broken, and the liquid medicine and the electrolyte are dissolved. An endothermic reaction was initiated by contact with a cryogen containing, and the gelling agent was allowed to absorb the electrolyte formed by mixing the liquid and the cryogen into the gelling agent. Ion-exchanged water is used as a liquid agent, a mixture of ammonium nitrate and urea at a weight ratio of 1: 1 is used as a cryogen, and a gelling agent obtained by polymerizing N-vinylacetamide is used as a gelling agent. The crosslinked product was dried and pulverized. When the cooling device thus prepared was applied to the neck by applying an external force to start an endothermic reaction and was attached to the neck, it did not slip off or fall off even after intense exercise, and an excellent cooling effect was obtained. .

Fifth Embodiment As shown in FIG. 12, the length of the surface 4 of the bag of the cooler A, which is in contact with the neck, the arm, etc., is made shorter than the length of the surface 5 on the opposite side. A cold insulator was prepared in the same manner as in Example 1 except that the shape of was curved. By bending the bag of cooler A in advance, when it is wound around a thin part, it does not wrinkle or bend, it can be closely attached to the part to be cooled without gaps, and an excellent cooling effect is obtained. I was taken.

Example 6 As shown in FIG. 13, FIG. 14, and FIG. 15, a cooling device was prepared in the same manner as in Example 1 except that the shape-retaining component 2 was housed inside the bag of the cooling device A. . When it was worn on the neck and checked the cooling effect, it was found that it adhered around the neck and did not slip off or fall off even after intense exercise, resulting in an excellent cooling effect.
