Description

  The present invention relates to a cooling body used by including water. The cooling body is used, for example, to cool a human or animal body by attaching it to clothes or bedding.

  This type of cooling body is known, for example, from Patent Document 1. There, a cooling body (cooler pad) is formed by covering the front and back of a highly water-absorbing sheet-like material spun with a polymer composed mainly of sodium polyacrylate with a polyester fabric that does not hinder the flow of water. This cooling body is used by being sandwiched between a hat and a head, for example. When a cooling body containing water is sandwiched between the hat and the head, the head surface can be cooled by utilizing the latent heat of vaporization when the water evaporates at body temperature.

  Further, a shirt equipped with this type of cooling body is known from Patent Document 2. There, a pocket is sewn on the inner surface of the upper edge center of the back body so that a cooling body can be taken in and out of this pocket. The pocket is formed by stitching together the arc edges of two mesh fabrics cut into a semicircular shape, and the linear upper edge is the entrance of the cooling body. The cooling body is formed by wrapping a water-absorbing polymer fiber absorbent body with a fabric having moisture permeability and water permeability. When a cooling body containing water is accommodated in the pocket, the neck circumference can be cooled using the latent heat of vaporization when the water evaporates at body temperature.

Registered Utility Model No. 3166664 (paragraph numbers 0013 and 0015) Japanese Patent No. 3525069 (paragraph numbers 0012 to 0014, 0019)

  In the cooling body of patent document 1, both surfaces of the highly water-absorbing sheet-like material are covered with a polyester fabric that does not hinder the flow of water, and water is leaked from both surfaces of the cooling body. Therefore, the water contained in the cooling body evaporates early and is lost. In other words, the cooling effect lasts only for a short time. In addition, when the cooling body of Patent Document 1 is attached to the inside of a garment, water contained in the cooling body leaks not only to the body side but also to the garment side, so that the clothes can be stained with water. Therefore, the cooling body of Patent Document 1 is difficult to attach to clothes such as a shirt worn in a formal situation.

  The cooling body mounted on the shirt of Patent Document 2 is formed by wrapping a water-absorbing polymer fiber absorbent body with a moisture-permeable and water-permeable fabric, and water is leaked from both sides. Therefore, like the cooling body of Patent Document 1, there is a problem that the duration of the cooling effect is short. Moreover, since the pocket which accommodates a cooling body is formed with the mesh fabric, the water contained in the cooling body oozes out to the surface of the shirt through the mesh fabric. Therefore, even if there is no problem in applying the shirt of Patent Document 2 to a sports shirt, there is a problem in appearance when it is applied to a shirt worn in a formal situation.

  Furthermore, in patent document 2, there exists a problem that it is difficult to accommodate a cooling body in a pocket. Since there is no core in the cooling body of Patent Document 2, in the process of pushing the cooling body into the pocket, the cooling body is bent by friction between the fabric of the pocket and the cooling body. Therefore, it is difficult to put the cooling body into the pocket, and it takes time to mount the cooling body. Since the pocket of the shirt of Patent Document 2 is arranged at the center of the upper edge of the back body, to attach the cooling body to the pocket while wearing the shirt, turn the hand behind the neck and perform the wearing work. There is a need to do. In the mounting operation performed in such a posture, if there is no core in the cooling body, the cooling body cannot be pushed into the pocket well, and in some cases, it is necessary to take off the clothes once.

An object of the present invention is to provide a cooling body capable of maintaining the cooling effect of the cooling body for a long time by evaporating water contained in the cooling body only on the surface to be cooled.
The purpose of the present invention is to prevent water from seeping out against the object to be worn, such as clothes, even though it is a cooling body that contains water. An object of the present invention is to provide a cooling body that can be attached to clothes without any problems.
An object of the present invention is to provide an easy-to-handle cooling body that can be quickly and accurately attached to a pocket for a cooling body provided in clothes or the like.

  The cooling body 3 according to the present invention includes a thin mat-shaped water absorbing body 21, a water permeable fabric 22 that covers one surface of the water absorbing body 21, and a waterproof sheet 23 that covers the other surface of the water absorbing body 21. And

  A plastic core member 24 having a shape maintaining function is disposed between the water absorbent body 21 and the waterproof sheet 23.

  The waterproof sheet 23 is composed of two waterproof fabrics 26 and 27 stacked on the inside and outside. The inner waterproof fabric 26 has a water repellent surface facing the water absorbent body 21, and the outer waterproof fabric 27 has an exposed surface opposite to the inner waterproof fabric 26 having a water repellent surface.

  The water absorbent body 21 is formed of a cloth fabric that has been subjected to raising treatment only on one side, and the water permeable fabric 22 is disposed on the raised surface side of the water absorbent body 21. The water-permeable fabric 22 is formed of a contact-cooled fabric.

  The water absorbent body 21, the water permeable fabric 22, and the waterproof sheet 23 are sewn together, and the water absorbent body 21, the water permeable fabric 22, and the waterproof sheet 23 are integrated.

  In the present invention, the cooling body 3 is configured by covering one surface of the water absorbent body 21 with the water permeable fabric 22 and the other surface of the water absorbent body 21 with the waterproof sheet 23. Therefore, the water contained in the water absorbent body 21 is permeable to the water permeable fabric. It can be evaporated only on the 22 side. Therefore, compared with the case where water is evaporated on both sides of the water absorbing body 21, the evaporation rate of water contained in the water absorbing body 21 is reduced, so that the cooling effect of the cooling body 3 can be maintained for a long time. Moreover, if water is evaporated only on the side of the water-permeable fabric 22, the water contained in the water absorbent 21 can be efficiently used for cooling the body.

  In addition, the cooling body 3 according to the present invention is a waterproof sheet 23 that allows water contained in the water absorbent body 21 to bleed into the garment when the water permeable fabric 22 is attached to the inside of the garment with the skin facing the skin surface. I can stop. That is, although the cooling body 3 according to the present invention is used by including water, the cooling body 3 can prevent the water from oozing out to the wearing object such as clothes, and is therefore worn in a formal situation. It can be worn without any problems on clothes such as shirts to cool the skin surface.

  The cooling body 3 according to the present invention can be mounted on a bedding such as a pillow. By attaching the cooling body 3 to the upper surface of the pillow with the water-permeable fabric 22 facing the head, the waterproof sheet 23 can prevent the water contained in the water absorbent body 21 from penetrating into the pillow. At this time, the cooling body 3 may directly touch the head, or a mesh fabric or the like may be interposed between the cooling body 3 and the head.

  When the core member 24 is disposed between the water absorbent body 21 and the waterproof sheet 23, the core member 24 can restrict the cooling body 3 from bending when the cooling body 3 is pushed into the pocket 7. It becomes easy to attach the cooling body 3 to 7. When the pocket 7 is placed at the back or back of the garment collar and the cooling body 3 is put on the pocket 7 while wearing the clothes, the cramped posture of turning the hand behind the neck or back However, even in the mounting operation performed in such a posture, if the bending of the cooling body 3 is restricted by the core member 24 as in the present invention, the cooling body 3 can be quickly moved with respect to the pocket 7. And it can be mounted accurately.

  Further, if the core member 24 has a shape maintaining function, even if the cooling body 3 is curved and deformed in accordance with the mounting target, if the cooling body 3 is removed from the mounting target, a force is applied in the direction opposite to the bending direction. Thus, the cooling body 3 can be returned to the original flat state and then mounted on another mounting target. That is, one cooling body 3 can be used properly among a plurality of mounting targets. Further, if the core member 24 is made of plastic, it will not rust like metal even if it is used repeatedly, so the life of the cooling body 3 is improved.

  When the waterproof sheet 23 is constituted by the two waterproof fabrics 26 and 27 stacked on the inside and outside, and the surface facing the water absorbent 21 in the inner waterproof fabric 26 is a water repellent surface, the water contained in the water absorbent 21 is waterproof inside. Therefore, it is possible to prevent water from leaking to the outer surface of the waterproof sheet 23 more reliably. Further, when the exposed surface of the outer waterproof fabric 27 is a water repellent surface, the water absorbing body 21 is soaked with water by, for example, immersing the entire cooling body 3 in water, and then adhered to the exposed surface of the outer waterproof fabric 27. The exposed surface can be dried by simply wiping off the water. Therefore, when the cooling body 3 is mounted on a mounting target such as clothes, the mounting target can be prevented from getting wet with water.

  When the water absorbent body 21 is formed of a cloth fabric subjected to raising treatment only on one side and the water permeable fabric 22 is disposed on the side of the raised surface of the water absorbent body 21, air is interposed in the raised surface between the water absorbent body 21 and the water permeable fabric 22. In addition, since the evaporation action can be promoted by increasing the chance of contact between water and air contained in the water absorbent body 21, the body can be effectively cooled. When the water-permeable fabric 22 is formed of a contact-cooled fabric, the cool feeling when the body touches the water-permeable fabric 22 can be improved as compared with the case where a general water-permeable fabric is used.

  When the water absorbent body 21 and the waterproof sheet 23 are stitched together, the water contained in the water absorbent body 21 may leak to the outer surface of the waterproof sheet 23 through the seam. On the other hand, as in the present invention, the water absorbent body 21 and the water permeable fabric 22 are stitched, the water permeable fabric 22 and the waterproof sheet 23 are stitched, and the water absorbent body 21 and the waterproof sheet 23 are prevented from being directly stitched. The water contained in the water absorbent 21 can be reliably prevented from leaking to the outer surface of the waterproof sheet 23 through the seam.

(Example 1) FIG. 1 thru | or FIG. 5 shows Example 1 which applied this invention to the cooling body for shirts. As shown in FIGS. 1 and 2, the shirt includes a shirt body 1, a collar portion 2 provided at the upper end of the shirt body 1, and a cooling body 3 that is detachably attached to the collar portion 2. The cooling body 3 is formed as a horizontally long strip-like body that can be bent. The collar portion 2 includes a base collar 5 sewn on the upper end of the shirt body 1 and an outer collar 6 sewn on the upper end of the base collar 5 and folded downward outward. On the inner surface of the collar 5, a pocket 7 for accommodating the cooling body 3 is formed along at least the rear half circumferential surface of the collar 5.

  When the pocket 7 is formed along at least the rear half of the inner surface of the collar 5, the left and right belt-like cooling bodies 3 are securely held on the inner surface of the collar 5 in a stable state, and a wide range around the neck Can be cooled for a long time. When the pocket 7 is formed over the entire length of the collar portion 2 in the circumferential direction, the left and right dimensions of the cooling body 3 can be increased accordingly, and the pocket 7 can be divided into two or four. can do.

  As shown in FIGS. 1 and 3, the pocket 7 is composed of a base collar 5 and a pair of upper and lower upper and lower flaps 11 and 12 sewn on the inner surface of the base collar 5. Each of the flaps 11 and 12 is made of a mesh fabric having a large number of holes and is formed in a horizontally long belt shape, and the vertical width thereof is set to be larger than half of the vertical width of the base collar 5. The upper flap 11 is disposed such that the upper edge thereof is along the upper edge of the base collar 5, and both side ends and the upper edge are sewn to the base collar 5. The lower flap 12 is disposed so that the lower edge thereof is along the lower edge of the base collar 5, and both side ends and the lower edge are sewn to the base collar 5. According to the pocket 7 configured as described above, it is possible to accurately cool the circumference of the neck facing the collar 5 while the cooling body 3 is held at the same height as the collar 5. The center of the upper edge of the back body of the shirt body 1 is not swollen outward by the cooling body 3, and the appearance can be maintained in a formal situation.

  Both the flaps 11 and 12 overlap the inside and outside in the state where the upper flap 11 is inside the pocket 7 at the upper and lower central portions of the base collar 5, and the cooling body 3 is placed between the free edges of both the flaps 11 and 12. The entrance / exit 13 to / from is opened. When the cooling body 3 is accommodated in the pocket 7, the entrance / exit 13 is at a height position facing the upper and lower centers of the cooling body 3. Accordingly, the cooling body 3 cannot be taken out from the pocket 7 unless the cooling body 3 is bent up and down or the doorway 13 is pushed and spread with a finger or the like, so that the cooling body 3 does not fall off carelessly. Moreover, if the space between the free edges of the flaps 11 and 12 that overlap the inside and outside is the entrance / exit 13, the entrance / exit 13 can be reliably kept closed without providing a closing means at the entrance / exit 13. Furthermore, since the flaps 11 and 12 can be reliably interposed between the cooling body 3 and the skin surface, it is possible to eliminate discomfort such as the cooling body 3 directly touching the skin surface and sticking the skin surface.

  As shown in FIG. 3, the base collar 5 includes a pair of inner and outer inner cloths 16 and 17, and both flaps 11 and 12 are sewn inside the inner cloth 16. The upper edge of the shirt body 1 is sandwiched between the lower edges of the inner cloth 16 and the outer cloth 17, and these three and the lower edge of the lower flap 12 are sewn together. Further, one end edge of the outer collar 6 is sandwiched between the upper edges of the inner cloth 16 and the outer cloth 17, and these three and the upper edge of the upper flap 11 are sewn together. Both end edges of the upper flap 11 and the lower flap 12 can be sewn to the inner cloth 16 before performing the above-described sewing, for example.

  As shown in FIGS. 4 and 5, the cooling body 3 includes a thin mat-shaped water absorbing body 21, a water-permeable fabric 22 that covers one surface of the water absorbing body 21, a waterproof sheet 23 that covers the other surface of the water absorbing body 21, It is comprised with the core material 24 distribute | arranged between the body 21 and the waterproof sheet 23. FIG. The waterproof sheet 23 is composed of two waterproof fabrics 26 and 27 stacked inside and outside.

  The water absorbent 21 is made of a cloth fabric having excellent water absorption used for disposable diapers and sanitary products. In this example, “BEL OASIS (registered trademark)” manufactured by Teijin Fibers Limited was used as the water absorbent 21. "Bel Oasis (registered trademark)" can absorb water about 7 times that of cotton and about 80 times its own weight, and the water absorbent body 21 according to this embodiment holds water for a maximum of about 8 hours. be able to. In order to increase the contact opportunity between water and air contained in the water absorbent 21 and promote the evaporation action, the surface of the water absorbent 21 on the side of the permeable fabric 22 is subjected to raising treatment. The water absorbent 21 may be made of a water-absorbing polymer, but the cloth fabric is advantageous in that the coefficient of expansion at the time of water absorption is smaller than that of the polymer, and the cooling body 3 is not bulky in the pocket 7.

  The water-permeable fabric 22 is preferably a contact-cooled fabric that is excellent in contact-cooled sensitivity. When the water-permeable fabric 22 is formed of a contact-cooled fabric, the cool feeling when the body touches the water-permeable fabric 22 can be improved as compared with the case where a general water-permeable fabric is used. The vertical and horizontal dimensions of the water permeable fabric 22 are set larger than the vertical and horizontal dimensions of the water absorbent body 21, and the periphery of the water permeable fabric 22 is folded back toward the water absorbent body 21.

  The waterproof fabrics 26 and 27 constituting the waterproof sheet 23 are formed by coating a plastic layer 31 on one side of the fabric fabric 30, and the plastic layer 31 is a water repellent surface that repels water. The inner waterproof fabric 26 is disposed with the plastic layer 31 facing the water absorbent 21, and the surface facing the water absorbent 21 is a water repellent surface. The outer waterproof fabric 27 is disposed with the plastic layer 31 facing outward, and the surface exposed to the outside is a water repellent surface. The vertical and horizontal dimensions of the inner waterproof fabric 26 are set larger than the vertical and horizontal dimensions of the water absorbent body 21, and the outer waterproof fabric 27 is formed to be slightly larger than the inner waterproof fabric 26. The periphery of the outer waterproof fabric 27 is folded back toward the water absorbent body 21, and the peripheral portion of the inner waterproof fabric 26 is sandwiched between the folded portions of the outer waterproof fabric 27.

  The core member 24 is formed in a horizontally long and slender strip shape, and is disposed along the upper edge of the cooling body 3. The core material 24 is made of a plastic such as polyethylene and has a thickness dimension of about 0.4 mm. In this example, “Free Shape FS-044” manufactured by Tetsu Masumi Co., Ltd. having a shape maintaining function was used as the core member 24. The upper half of the core member 24 is sandwiched between the peripheral edge of the outer waterproof fabric 27 folded and the peripheral edge of the inner waterproof fabric 26, and the lower half of the core member 24 is the water absorbent 21. It is sandwiched between the upper end portion and the inner waterproof fabric 26.

  When the horizontally long core material 24 is arranged, the core material 24 can restrict the cooling body 3 from bending along the direction perpendicular to the longitudinal direction of the core material 24, that is, the vertical direction. It is possible to facilitate the mounting work of pushing the inward into the pocket 7 in the left-right direction. In order to mount the cooling body 3 while wearing the shirt, it is necessary to turn the hand behind the neck. Even in such a mounting operation performed in a cramped posture, the cooling body 3 is bent by the core material 24. By regulating the above, the cooling body 3 can be quickly and accurately attached to the pocket 7. Further, if the core member 24 has a shape maintaining function, even if the cooling body 3 is curved and deformed in accordance with the mounting target, if the cooling body 3 is removed from the mounting target, a force is applied in the direction opposite to the bending direction. Thus, the cooling body 3 can be returned to the original flat state and then mounted on another mounting target. That is, one cooling body 3 can be used properly among a plurality of mounting targets.

  The water absorbing body 21, the water permeable fabric 22, the waterproof sheet 23, and the core member 24 constituting the cooling body 3 are integrated by stitching. Specifically, first, the water absorbent body 21 and the water permeable fabric 22 are sewn along one suture line 35 extending in the left-right direction. Next, the inner waterproof fabric 26 and the core material 24 are sandwiched between the overlapping portions of the outer waterproof fabric 27 that are folded back, and the water-absorbent body 21 and the water-permeable fabric 22 that have been stitched together are overlapped. At this time, the core member 24 and the inner waterproof fabric 26 are opposed to the water absorbent body 21. Finally, the overlapped portions of the water-permeable fabric 22 and the outer waterproof fabric 27 that are folded back are stitched together along a circumferential stitch line 36. In the stitching along the stitching line 36, the water-permeable fabric 22, the core member 24, and the waterproof fabrics 26 and 27 inside and outside are stitched, but the water absorbent 21 is not stitched. Thus, if the water absorbing body 21 and the waterproof sheet 23 are prevented from being directly stitched, it is possible to reliably prevent the water contained in the water absorbing body 21 from leaking to the outer surface of the waterproof sheet 23 through the seam.

  When the cooling body 3 is immersed in water or water is applied to the cooling body 3, the water is absorbed by the water absorbing body 21 through the water-permeable fabric 22. After the water-containing cooling body 3 is lightly squeezed, it is accommodated in the pocket 7 with the water-permeable fabric 22 facing the flaps 11 and 12 and the waterproof sheet 23 facing the base collar 5 (see FIG. 3). The cooling body 3 may be accommodated before or during wearing of the shirt. By disposing the waterproof sheet 23 on the side of the base collar 5, it is possible to prevent the water contained in the water absorbent body 21 from oozing out to the base collar 5.

  When a shirt equipped with a cooling body 3 containing water is worn, the temperature of the water contained in the water permeable fabric 22 side of the water absorbent body 21 rises and evaporates due to the heat of the skin surface of the wearer. Since the temperature of the skin surface of the wearer is lowered by the endothermic action at this time, the wearer feels cool. As long as the water contained in the water absorbent body 21 continues to evaporate, the cool feeling around the neck is maintained. If the water in the water-absorbing body 21 is almost evaporated and a cooling sensation cannot be obtained, the cooling sensation can be obtained again by taking out the cooling body 3 from the pocket 7 and re-inserting it in the pocket 7 after adding water again. Can be obtained. In addition, when the cooling effect by the cooling body 3 is not required, such as other than in summer, the shirt may be worn with the cooling body 3 removed.

(Example 2) FIGS. 6 and 7 show Example 2 in which the present invention is applied to a cooling body for a T-shirt. Here, the pocket 7 is formed by the back body 41 of the T-shirt and a pair of upper and lower flaps 43 and 44 sewn on the inner surface of the upper center of the back body 41. Each of the flaps 43 and 44 is made of a mesh fabric. The upper flap 43 is formed in a belt shape along the upper edge of the back body 41, and the lower flap 44 is formed in a semicircular shape along the lower edge of the upper flap 43. Is formed. Between both the flaps 43 and 44, an entrance / exit 45 through which the cooling body 3 is taken in and out is opened.

  The cooling body 3 is formed in a substantially semicircular shape, and a vertically long and slender strip-shaped core member 24 is disposed at the center in the left-right direction. The water absorbent body 21 and the water permeable fabric 22 are sewn along two X-shaped suture lines 48, and the water permeable fabric 22, the waterproof sheet 23, and the core member 24 extend along the periphery of the cooling body 3. It is sewn along a circumferential suture line 49. When the vertically long core member 24 is arranged, the core member 24 can restrict the cooling body 3 from bending along a straight line in the left-right direction, so that the mounting work of pushing the cooling body 3 into the pocket 7 in the vertical direction is performed. It can be simplified. Since other configurations are the same as those of the first embodiment, the corresponding portions are denoted by the same reference numerals and description thereof is omitted.

  In addition, the two waterproof fabrics 26 and 27 constituting the waterproof sheet 23 do not need to be separate, and the waterproof sheet 23 may be configured by folding one waterproof fabric in half. The waterproof sheet 23 may be formed of a single waterproof fabric in which the plastic layer 31 is coated on both sides of the fabric fabric 30. Moreover, as the waterproof sheet 23, a plastic sheet, a nonwoven fabric laminated with a plastic film, or a plastic film coated with aluminum can be applied. The waterproof sheet 23 may also serve as the core member 24.

  The core material 24 does not need to have a strip shape, and can be formed in a lattice shape. A plurality of core members 24 may be arranged on one cooling body 3. The core material 24 does not need to be a plastic sheet having a shape maintaining function, and can be formed of a normal plastic sheet or an interlining. It may be a plastic sheet containing an antibacterial agent. In addition, although the core material 24 may be arrange | positioned between the water absorbing body 21 and the water permeable fabric 22, in that case, since the core material 24 prevents the movement of the water | moisture content between the water absorbing body 21 and the water permeable fabric 22, The core member 24 is preferably disposed between the water absorbent body 21 and the waterproof sheet 23.

  The cooling body 3 according to the present invention can be mounted not only on a shirt and a T-shirt, but also on Japanese clothes such as a yukata, bedding such as a pillow, or clothes for pets. The shape of the cooling body 3 is not limited to that shown in each of the above embodiments, and can be freely set according to the mounting target, such as a circle, an ellipse, a quadrangle, and a triangle. An adhesive tape or a hook-and-loop fastener is provided on the outer surface of the waterproof sheet 23 of the cooling body 3, and the cooling body 3 can be mounted via these.
