Description

  TECHNICAL FIELD The present invention relates to a bag body for storing a cooling body, and more specifically, cooling for body heat cooling used to cool a part of a human body including a head, an armpit, a base of a foot, and a neck. The present invention relates to a body storage bag.

  In general, when heat is generated, the head and the armpit are cooled, and cooling is performed by placing a water pillow or ice bag or a refrigerant containing the refrigerant on the head and armpit.

  What stored the refrigerant | coolant is what used as the cool mat | matte which accommodated the gel-shaped cold insulating material in the resinous cover, etc., for example. The cold insulation mat is pre-cooled in a refrigerator or the like, and is used by covering the cold insulation mat in a cooled state with an external cover made of cloth or a towel.

  As another method of cooling the heat of the head, the armpit, etc., a sheet material for heat cooling that is attached to the human body is sold. The heat-cooled sheet material has, for example, the same structure as a cooling poultice used by being attached to the skin, and is a laminate composed of a support, a plaster and a release liner in order from the surface. Examples of the agent include those in which a refreshing agent such as mint oil or menthol or a cooling agent is mixed with the base.

  However, even when using water pillows, ice packs, refrigerant containing sheets, and heat-cooling sheet materials, the environment in which they are used may be hot and humid. In particular, a human body part covered with clothes such as the armpits is also sweaty during heat generation, and is in a hot and humid state compared to a part that touches the outside air such as the head.

  For this reason, dew condensation occurs around the cold insulation material due to the action of cooling the cold insulation material such as water pillows, ice packs, refrigerants, and sheet materials for heat-cooling. In the case of use on a human body part that is covered with clothes such as the armpit, there is a problem that the clothes are also wetted.

  In addition, when heat is generated, cooling the parts such as the armpit and the base of the foot has a great effect on the heat release. However, it is difficult to closely attach a cold insulating material such as a water pillow, an ice sac, or a refrigerant containing the material to the part, and further, due to the movement of the human body, the cold insulating material is displaced from the part, and the effect of heat cooling cannot be obtained. The condition is happening well.

  In some cases, the cold insulating material is fixed to a band or the like, and the band is wound around the human body so that the cold insulating material is in close contact with the human body. However, the use of the band is accompanied by the uncomfortable feeling of tightening the human body, and there is a part where the band cannot be tightened, and there is a problem that the part where the cold insulation material is to be adhered is restricted. In addition, since it constitutes a band, it is difficult to produce a product at a low price, and it is difficult to obtain ease of use.

  In that respect, since the heat-cooling sheet material is used by being stuck to a human body part, it can be brought into close contact with a part such as the armpit or the base of the foot, and can be prevented from being displaced due to the movement of the human body. However, because the heat-cooling sheet material dissipates the heat of the human body through the heat-cooling sheet material, the body part covered by clothes such as the armpits and the base of the foot is exposed to the outside air such as the head. Since it is in a hot and humid state compared with the touched part, the effect of dissipating the heat accumulated in the body is poor, and a sufficient heat cooling effect cannot be obtained.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a bag body for storing a cooling body, which can absorb the condensation that occurs during cooling, in order to eliminate the above problems. There is to do. In addition to the above object, another object of the present invention is to provide a cooling body storage bag body in which the cooling body storage bag body is brought into close contact with a portion to be cooled to prevent the cooling body from shifting. . Furthermore, in addition to the above object, an object of the present invention is to provide a cooling body storage bag body that can be disposable after use by manufacturing the cooling body storage bag body with an inexpensive material. .

  In order to achieve the above object, the bag for storing a cooling body according to the present invention is a water-absorbent water-absorbent dry sheet or a liquid-permeable dry sheet formed using a hydrophobic material. A dew condensation prevention sheet is formed by overlapping the sheets, and the dew condensation prevention sheet is formed in a bag so that the dry sheet is on the surface.

  The bag body is stored with a cooling body, for example, a cold insulating material in which a gel-like cold insulating material is stored in a resinous cover, and then the bag body in which the cooling body is stored is brought into close contact with a portion to be cooled. The adhering part is cooled, and at this time, due to the configuration of the bag body, the dew that is generated by being cooled by the cooling body is absorbed by the absorbent sheet through the dry sheet, and in the contact part with the adhering part, The dry sheet prevents direct contact with the water-absorbent sheet and does not get wet because the dry sheet is made of a hydrophobic material. That is, when the bag body is used for cooling the body heat, it is possible to prevent a feeling of getting wet at the close contact portion with the human body and to prevent discomfort during the body heat cooling.

  In addition, the temperature control using heat insulation can be enabled by changing the thickness of the water absorbent sheet. By increasing the thickness of the sheet, it is possible to prevent excessive cooling at the moment when the bag body is brought into close contact, and to gradually continue the cooling effect of the cooling body for a longer time.

  In the cooling body storage bag of the present invention, a water-absorbent water-absorbent sheet is superposed on a liquid-permeable or water-absorbent dry sheet formed into a sheet using at least a hydrophobic material. After forming the dew condensation preventing sheet and making the dew condensation preventing sheet with the dry sheet on the surface, an adhesive surface is formed on at least one surface of the bag body, and the release sheet is formed on the adhesive surface. It is characterized by being arranged.

  After the cooling body is stored in the bag body, when the bag body in which the cooling body is stored is brought into close contact with the part to be cooled, the part to be attached is formed by forming an adhesive surface on at least one side of the bag body The bag can be brought into close contact directly and easily. Thereby, while the bag is in close contact with the human body and being used for body heat cooling, the bag can be prevented from being displaced due to the movement of the human body, and the cooling effect of the cooling body can be continuously provided. It is.

  When the bag body is used for body heat cooling, the bag body in which the cooling body is housed can be used not only in direct contact with the human body but also in contact with clothing. Since the bag is composed of a dew condensation prevention sheet in which a dry sheet and a water absorbent sheet are superposed, the surface of the bag is not wet and is in a smooth state. For this reason, even if the bag body is directly adhered to the clothes and used, the clothes are not wetted and no uncomfortable feeling is given.

  Furthermore, the cooling body storage bag according to the present invention is configured as a bag only by a dew condensation prevention sheet in which a dry sheet and a water absorbent sheet are overlapped, and depending on the purpose, an adhesive surface is formed on at least one side of the bag. Therefore, it can be manufactured at a low price. Thereby, after using the said bag body in which the cooling body was accommodated, the said cooling body is taken out from the said bag body, and only the said bag body can be disposed and can be used disposable.

  As described above, in the bag for storing a cooling body of the present invention, condensation can be actively absorbed, and the bag body is formed by forming an adhesive surface on at least one side of the bag body. Can be brought into close contact with the portion to be cooled to prevent the cooling body from shifting. Furthermore, by using an inexpensive material, it becomes easy to dispose after use, and exhibits excellent hygienic effects.

BEST MODE FOR CARRYING OUT THE INVENTION

  Embodiments of the cooling body storage bag of the present invention will be described below.

  FIG. 1 is a schematic view of a dew condensation preventing sheet for making a bag for storing a cooling body of the present invention. The anti-condensation sheet is formed by superposing a dry sheet 1 and a water absorbent sheet 2. The dry sheet 1 and the water absorbent sheet 2 may be simply stacked one above the other, may be stacked using an adhesive, or may be stacked several times with a needle or the like after being stacked one above the other. The fibers constituting the dry sheet and the water-absorbent sheet may be entangled with each other.

  The dry sheet 1 is a sheet obtained by forming a hydrophobic material such as a polyester resin or a polypropylene resin into a fiber and making it into a knitted or non-woven fabric using at least the fiber. And when making into a knitted or woven fabric or a nonwoven fabric, the density of the said fiber is made coarse, or a liquid-permeable characteristic is given to the said sheet | seat by making it mesh shape. Thereby, the water | moisture content produced by the condensation permeate | transmits the said dry sheet | seat 1, and is water-absorbed by the water-absorbing sheet 2 piled up.

  In addition, the dry sheet 1 is also a sheet formed from a fiber bundle using at least fibers made of a hydrophobic material such as a polyester resin or a polypropylene resin, and is formed into a sheet by the fiber bundle. A fiber bundle obtained by bundling a large number of thin fibers can temporarily absorb water between the fibers by capillary action. And the water | moisture content temporarily absorbed in water permeate | transmits the said dry sheet 1, and is absorbed in the water-absorbing sheet 2 piled up.

  And the said dry sheet | seat 1 is comprised using at least what fibrillated hydrophobic materials, such as a polyester resin and a polypropylene resin. Since the fiber by the hydrophobic material does not absorb moisture, if the moisture generated by condensation or sweating is absorbed by the water absorbent sheet 2, the surface of the fiber can be kept dry. Therefore, the dry sheet 1 can be prevented from giving a wet feeling to the human body, that is, it can give a smooth feel.

  The hydrophobic material used for the dry sheet 1 is desirably used in an amount of at least 50% by weight in order to give a smooth feel.

  The water-absorbent sheet 2 is a sheet made into a knitted fabric and a non-woven fabric using fibers made of a water-absorbing material. Examples of the fiber made of a water-absorbing material include cotton and water-absorbing polyester fiber. Further, when a sheet is formed using a bundle of fibers obtained by bundling a large number of fibers, moisture can be absorbed between the fibers by capillary action. Therefore, a sheet material using a fiber bundle made of a water-absorbing material becomes a sheet material excellent in water absorption.

  In addition, the pulp etc. which are the fibers taken out from the wood are also water-absorbing materials, and the paper made from the pulp can also be used as the water-absorbing sheet 2.

  Further, the water absorbent sheet 2 may be a sheet formed by adhering a water absorbent polymer material to a woven or non-woven fabric of natural or synthetic fibers. In this case, the fibers used may be fibers made of either hydrophobic or water-absorbing materials. The water-absorbing polymer has a function of containing the absorbed water, preventing the water-absorbing polymer from changing into a gel and flowing back to the outside of the water-absorbent sheet 2. In consideration of the fact that the anti-condensation sheet comes into contact with the human body, it is preferable to use a water-absorbing polymer having no toxicity and irritation in oral toxicity and skin irritation tests.

  FIG. 2 is a schematic diagram showing one shape of a cooling body storage bag body made from the dew condensation prevention sheet. When making a bag from the dew condensation prevention sheet to the cooling body storage bag body, the dry sheet 1 contacts the surface of the bag body, that is, the surface that contacts the human body, and then contacts the back surface of the bag body, that is, the cooling body. The bag is made so that the water-absorbent sheet 2 is disposed on the surface to be performed.

  Moreover, although the shape of the said bag body is based also on the shape of the cooling body inserted, square shape is easy to manufacture and manufacturing cost can also be made low-cost. However, the shape of the bag-making may be a shape other than a quadrangle, for example, an elliptical shape, in order to more closely match the portion to be cooled.

  FIG. 3 is a schematic view showing the usage of the folded cooling body storage bag body 5 having a folded portion so that the cooling body 4 does not jump out of the bag making.

  The cooling body 4 includes, for example, a gel-type cold-retaining material housed in a resinous cover, a concealed bag body with a liquid such as water confined in water.

  After the cooling body 4 is sufficiently cooled by a refrigerator or a freezer, the cooling body 4 is inserted into the folded-back cooling body storage bag body 5, the folded portion of the cooling body storage bag body 5 is folded back, and the cooling body 4 is It is confined in the cooling body housing bag 5. Thereby, the cooling body 4 jumps out of the cooling body storage bag body 5 with respect to the movement of a human body or the like during cooling with the cooling body storage bag body 5 storing the cooling body 4 in close contact. Can be easily prevented.

  As another method of confining the cooling body in the cooling body storage bag body, an adhesive tape or a surface fastener is attached to the opening of the bag body so that the cooling body does not jump out of the cooling body storage bag body. It is also possible to do so.

  FIG. 4 and FIG. 5 are schematic views of a cooling body storage bag body in which an adhesive surface is formed on at least one surface in order to make the cooling body storage bag body adhere to a portion to be closely attached.

  In order for the cooling body storage bag to be in close contact with the human body or clothes, and to prevent the bag body from being displaced or disengaged from the cooling site with respect to the movement of the human body such as when being cooled by heat, the It is desirable to form an adhesive surface on at least one surface and attach the bag body directly to the human body or clothing.

  As the formation of the adhesive surface, for example, one side of a sheet coated with an adhesive is pasted on the surface of the bag for storing a cooling body, and the other side of the adhesive-coated sheet is formed with an adhesive surface. There is a way. There is also a method in which an adhesive is directly applied to one surface of a cooling body housing bag to form an adhesive surface.

  As the adhesive, since the adhesive surface directly touches the human body, it is desirable to use an ingredient having no toxicity and irritation in oral toxicity and skin irritation tests.

  FIG. 4 is a schematic view in which a wide adhesive application sheet 6 is attached to the entire surface of at least one side of the bag body, and FIG. 5 shows a plurality of narrow adhesive application sheets 7 spaced apart. It is the schematic stuck on at least one surface of the body.

  As shown in FIG. 4, by forming an adhesive surface on the entire surface of one side of the cooling body housing bag, it is possible to further enhance the adhesion between the human body and clothes. In addition, as shown in FIG. 5, by forming an adhesive surface on one side of the bag for storing the cooling body instead of the entire surface, air permeability on the contact surface with the human body and clothes is secured, and from the human body Since it is possible to absorb the sweat caused by the perspiration of the water in the cooling body housing bag, it is possible to prevent the human body from feeling uncomfortable.

  In FIG. 5, the adhesive surface is formed on one side of the cooling body storage bag body using a narrow adhesive coating sheet, but an adhesive coating sheet such as a round shape or a square shape is pasted. The adhesive surface may be formed by attaching or directly applying an adhesive to a round shape or a square shape.

  And after forming an adhesive surface, in order to maintain the adhesive force of an adhesive surface until the said bag body accommodates and uses a cooling body, it is good to arrange | position a peeling sheet on an adhesive surface.

  It is the schematic of a dew condensation prevention sheet.   It is the schematic of the bag body for cooling body accommodation.   It is the schematic showing the state which inserts a cooling body in the folding-backed cooling body storage bag body, and then folds the folding | turning part of the said bag body and accommodates a cooling body.   It is the schematic which affixed the adhesive application wide sheet | seat on the single side | surface of the bag body for cooling body accommodation, and formed the adhesive surface in the single side | surface whole surface of the said bag body.   It is the schematic which affixed several adhesive application thin width sheets with the clearance gap on the single side | surface of the bag body for cooling body accommodation, and formed the adhesive surface with the clearance gap on the single side | surface of the said bag body.
