Abstract
Description
Technical Field
[0001] The present invention relates to a hat that cools the head and the surrounding area such as the back neck muscles by the heat of vaporization of water, or a cooling structure such as a zukin.
Background Art
[0002] Conventionally, as a structure for cooling by the heat of vaporization of water, a sheet-like water-absorbing material that is relatively thick and can absorb and store several times its own weight of moisture is covered with a front fabric and a back fabric through which moisture passes, and is placed at a position corresponding to the back of the head or the back neck muscles of a hat or a zukin. The components are immersed in water, lightly wrung out, and worn to obtain a cooling sensation. In this case, in order to sufficiently absorb and store water in the water-absorbing material, a container for storing water such as a washbasin or a plastic bag container is required. It is necessary to leave it in the water for about one minute to absorb the moisture, then lightly wring it out to remove excess moisture, and then wear it on the head. Considering the scenes used in tennis courts, golf courses, hiking, jogging, etc. in midsummer, it is extremely inconvenient to carry the above-mentioned water storage container and the water to be put into it. Also, a method of dripping water from above onto the above-mentioned sheet-like cooling structure portion can be considered, but the water splashes around and is uncomfortable. Moreover, if this is done in a car during driving towards a midsummer recreation or sports venue, it is obvious that the water splashes in the narrow car interior and is even more uncomfortable.
[0003] Patent Document 1 discloses a hat that is equipped with a plastic bag container for storing water, the cap body portion of the hat with a water-absorbing material attached to the cap body portion is immersed in the above-mentioned water, and then covered on the head to cool the head by the heat of vaporization and be useful for heatstroke prevention. However, after immersing the cap body portion in water, there are nuisances such as wringing out excess water from the wet cap body portion, splashing water around, and discarding excess water after use.
[0004] Patent Document 2 discloses a configuration in which a pad made of a water-absorbing material is attached to a portion of a hat body that contacts a person's forehead, and the pad is detachable to obtain a cooling sensation on the forehead due to the effect of latent heat of vaporization. Even in this case, the pad portion was not free from the nuisance of water splashing around, such as by immersing it in water contained in a water storage container or spraying water from a faucet.

Summary of the Invention
Problems to be Solved by the Invention
[0006] The present invention aims to obtain a cooling structure by the effect of latent heat of vaporization without immersing, dripping, or wetting the front surface or the back surface of the hat body such as a cap or a hood in water, and without having a water storage container.
Means for Solving the Problems
[0007] The structure provided in the hat or the like of the present invention is configured by providing a water injection port at the top of the hat body where water can be injected from a plastic bottle or a cup, etc., and covering the back surface side of the hat body with a moisture-permeable waterproof cloth that has a planar shape and has holes in one or both sides of the water-absorbing material and at various parts thereof as vaporization ventilation windows. Then, a gap through which water flows is provided as a water channel between the water-absorbing material and the moisture-permeable waterproof cloth so that the injected water flows from top to bottom and evenly from left to right over the water-absorbing material arranged in a planar shape within the hat body, and the water-absorbing material can absorb and store moisture. In addition, in the case of a hat having a cap body part and a flap part connected to the cap body part and covering the back of the head and the upper part of the back neck muscle, or an inner headscarf worn under a helmet, such as a nursing gown for caregivers, etc., a connecting water channel part is provided at the connecting part so as to avoid the peripheral size adjustment part of the hat or the like, and the water injected from the water injection port passes through the gap space of the cap body part and flows into the water absorbent material arranged in a planar shape on the flap part. Further, the connecting part is configured to have a structure connected by a so-called groove and pipe method in which the water channel width from the cap body part made of a moisture permeable waterproof cloth is reduced, the water channel width from the flap part is increased, and an overlapping part is provided. When the cap body part and the flap part are separately manufactured and assembled by bonding and sewing in the final process, an efficiently and neatly finished structure is provided. Furthermore, a drain port for intensively draining the excess water after the water injected from the water injection port has sufficiently absorbed water into the water absorbent material is provided at the lowermost end of the flap part, and a structure for detecting that water has started to flow from there and knowing an appropriate amount of the water injection amount from the water injection port is also provided.
Advantages of the Invention
[0008] The structure provided in the hat or the like of the present invention can uniformly supply moisture all at once to the upper and lower, left and right of the planar water absorbent material arranged at the connected part of the cap body part and the flap part, which cover the human head, the back of the head, and the back neck muscle, by injecting water from a water injection port provided at the top of the head from a PET bottle or a cup. It is expected that a cooling effect due to the vaporization heat action can be obtained quickly. Also, in the case of a hat or a nursing gown having a cap body part and a flap part connected to the cap body part and covering the back of the head and the upper part of the back neck muscle, by injecting water from the water injection port provided at the top of the head, a cooling effect due to the vaporization heat action can be obtained by injecting water only once from one water injection port from the upper cap body part of the hat or the like to the lower flap part.
[0009] According to the present invention, it is no longer necessary to immerse the cap body part and the flap part in water stored in a washbasin or a plastic bag container as in the prior art. In recent years, the installation of vending machines that sell cold water in PET bottles has become widespread. Cold water in PET bottles can be easily and constantly obtained at lounges attached to sports club houses such as golf courses and tennis courts, as well as on street corners. In particular, during the peak of summer, players often carry it with them at all times during play. When a player wears a hat with the structure related to the present invention, even when the cooling effect due to the heat of vaporization decreases due to the evaporation of the moisture during a long play, the player can quickly and easily add cold water from the PET bottle carried with them to the water injection port, quickly restoring and strengthening the cooling effect on the entire surface of both the cap body part and the flap part of the hat, enabling the resumption of the play. Furthermore, since this water injection action can be carried out at any time and anywhere in front of acquaintance players of the same group, the hat of the present invention can be proud of its ability to maintain the cooling effect for a long time and be very useful for preventing heat stroke. It is expected to have an epoch-making effect of inspiring and popularizing heat stroke prevention measures and a great sales promotion effect for the product, making it easy to recommend the purchase of the hat of the present invention to friends and others.
[0010] Also, in a conventional flap hat for children with a cooling function based on the heat of vaporization, tap water or the like was poured over the sheet-like water-absorbing fiber attached to the back side of the flap part of the hat to absorb the moisture. For example, when a large number of kindergarten children did this, water splashed around the water tap, and the children's clothes also got wet. When the structure related to the present invention is used for a flap hat for children, if a large number of kindergarten children, under the teacher's command, simultaneously hold the flap hat with the structure of the present invention in one hand and a cup containing about 100 ml of water in the other hand, and just pour water from the water injection port of the structure of the present invention, and then, if it is taught to stop the water injection when detecting the dripping of excess water from the drain port provided at the lower end of the flap part, then, as described above, without splashing water and without wetting the children's clothes, and then wearing the flap hat, a cooling effect from the head to the neck muscles due to the heat of vaporization can be obtained, which has a great effect of helping with heat prevention and heat stroke prevention measures for children's outdoor activities in the peak of summer.

Embodiments for Carrying Out the Invention
[0012] Regarding a first preferred embodiment example in the case of a hat according to the structure of the present invention, it will be described more specifically with reference to the drawings. FIG. 1 is a diagram showing a cross-section of the structure of a hat using the present invention. The hat 1 is composed of a brim portion 11, a hat body portion 12, and a flap portion 13 located at the rear. FIG. 1 also shows a cross-section of the back side of the portion covering the upper part of the neck muscles from the back of the head of this hat 1. A water injection port 1a through which water can be injected is provided near the top of the cap body 12 of the hat 1. Further, A first water absorbent material 14 that absorbs several times its own weight of moisture is disposed in a planar shape so as to cover the back of the head of the cap body 12. Also, in the flap portion 13, a second water absorbent material 15 similar to the water absorbent material is disposed in a planar shape so as to cover the upper part of the back of the neck.
[0013] These first and second water absorbent materials 14 and 15 are covered with moisture permeable and waterproof fabrics 16 and 17 on both sides thereof. Further, for example, a planar gap 18 is provided between the moisture permeable and waterproof fabric 16 on the outer surface and the surfaces of the first and second water absorbent materials so that the water injected from the water injection port 1a flows and reaches the first and second water absorbent materials 14 and 15, and the moisture can be absorbed, adsorbed, and stored. However, in the foregoing description, the water absorbent materials 14 and 15 are described separately as the first and second. Even when they are provided as a moisture absorbent material 3b1 having an integral structure shown in FIG. 3b continuously, as will be described below, the effects are different, but it is hereby specified that the present invention can provide a feasible configuration.
[0014] Next, FIG. 2 is a view showing the back of the structure of the hat using the present invention. Generally, the hat has a space of a head circumference size adjustment part 21 and an adjustment band 22 at the rear center part of the cap body 12 in order to fit the peripheral size of a person's head. Also, in the case of a flap hat for children or toddlers, etc., there is also a rubber expansion and contraction part 92 for size adjustment at the rear center part of the cap body as shown in FIG. 9. In these size adjustment parts 21, the water absorbent materials 14 and 15 having a thickness and hardness (a Gore-Tex-like feeling) several times that of a general cloth fabric, and the moisture permeable and waterproof fabrics 16 and 17 for forming a water channel for smoothly flowing water cannot be disposed. Therefore, in order to avoid the size adjustment part 21 and allow the water injected from the water injection port to be absorbed by the first water absorbent material 14 of the cap body part and then absorbed by the second water absorbent material 15 disposed in the lower flap part, for example, as shown in FIG. 2, it is necessary to obtain a structure in which a connecting water channel part 23 for avoiding the size adjustment part and flowing water into the second water absorbent material 15 in the flap part 13 is disposed.
[0015] Figure 3a is a diagram showing a combined configuration of a plurality of fabrics and members that make up the present invention. Among the plurality of fabrics and members shown in the diagram of Figure 3a, on the surface side of a person's head when wearing a hat or the like, for both the hat body part and the flap part, there is a highly breathable lining 31 located on the surface of the person's head. Next, an inner moisture-permeable waterproof fabric 17 with holes for vaporization and ventilation is arranged at various places, and on the outside thereof, the water-absorbing materials 14 and 15 are attached by adhesion or sewing. Then, an outer moisture-permeable waterproof fabric 16 is placed to cover these, and the inner moisture-permeable waterproof fabric 17 and the outer moisture-permeable waterproof fabric 16 are joined at the outer periphery of their shapes by adhesion or sewing, so that the water injected from the water injection port 1a can form a water channel 18 on the surfaces of both the hat body part 12 and the flap part 13 while being absorbed and stored by the water-absorbing material surfaces 14 and 15. At this time, as shown in Figure 3b, by continuously integrating the first and second water-absorbing materials 14 and 15 to cover the hat body part and the flap part as a water-absorbing material 3b1, the cooling effect due to the vaporization heat action obtained in the present invention can be achieved.
[0016] However, by separating the water-absorbing material into moisture-absorbing materials 14 and 15 for the hat body and the flap part, and in the connecting water channel part 23 that connects the hat body part 12 and the flap part 13, there is no thick and bulky feeling like in the case of the integrated water-absorbing material 3b1. Therefore, by making it a water channel only with a soft moisture-permeable waterproof fabric, as shown in Figure 8, from the perspective of fashionability, it looks as if only an ordinary hat body part is being worn, and the flap part 13 can be neatly and neatly folded into the hat body part 12 for storage, resulting in the effect that it can be worn without a sense of discomfort. In the figure, 32 is the surface fabric of the hat body part 12 and the flap part 13.
[0017] Next, a second embodiment with an even higher effect of the present invention will be described. A hat having a structure like the present invention is generally such that the hat body part 12 and the flap part 13 are manufactured separately and then joined by sewing. In order to perform this joining assembly efficiently and easily, the connecting water channel part 23 of the hat having the structure of the present invention is configured as follows. As shown in FIG. 3c, the width of the connecting water channel part 3c2 composed of the inner and outer moisture-permeable waterproof fabrics 17b and 16b on the flap part side is wider than the width of the connecting water channel part 3c1 composed of the inner and outer moisture-permeable waterproof fabrics 17a and 16a incorporated in the hat body part 12, and when the water channels of the hat body part 12 and the flap part 13 are joined, they overlap vertically. For example, the connecting water channel part 3c1 on the hat body side is configured to be long.
[0018] The configured hat body part 12 and flap part 13 are separately assembled and manufactured. When sewing the connection around their horizontal circumferences later, sewing is performed avoiding the connecting water channel part 23. The connecting water channel part 23 is formed by inserting a cylindrical water channel part 3c1 composed of the moisture-permeable waterproof fabric on the hat body side into a slightly larger-diameter cylindrical water channel part 3c2 on the flap part 13 side and connecting them in a sleeve tube manner to generate the aforementioned connecting water channel part 23. Since only the connecting water channel parts of the hat body part 12 and the flap part 13 are avoided and the entire horizontal circumference can be connected, for a hat having the structure of the present invention or, for example, a ski mask of a helmet inner, as the aforementioned connecting part through which water flows, while obtaining the connecting water channel part 23, the effect of extremely efficiently simplifying its assembly can be obtained.
[0019] FIG. 4 is a view showing a cross-section of the connecting water channel part 23 of the hat using the aforementioned present invention. This cross-section shows a view of the structure in the case of the aforementioned sleeve tube method as seen by cutting along the cross-section line 2a shown in FIG. 2. It is explained that the connecting water channel part 23 is configured such that the aforementioned connecting water channel part 3c1 on the hat body side and the connecting water channel part 3c2 on the flap side, which is wider and larger in width and diameter on its outer side, are connected by the sleeve tube method, avoiding the band part 22 of the size adjustment part 21, and on both sides thereof, the aforementioned water 41 flows from the hat body side to the flap part side. FIG. 5 is a view showing the bottom surface of the hat used in the present invention. The arrangement configuration of the vaporization ventilation windows 51 and 52 provided in the inner moisture permeable waterproof fabrics 17a and 17b is shown to promote the vaporization cooling effect of the moisture absorbed by the water absorption materials 14 and 15.
[0020] Figure 6 is a graph showing the cooling temperature effect of the hat with the structure used in the present invention. At around 13:00 on a sunny day in summer, about 100 ml of cold water (around 12 °C) was poured into the water injection port 1a of the hat having the structure of the present invention, and it was worn 10 minutes later. Then, for several hours, the wearer took a walk in the street corner, park, watched a competition, etc. During that time, the surface temperature 61 of the front surface of the top of the hat body 12, the temperature 62 of the back surface of the rear part of the hat body (on the human body side), and the temperature 63 of the inner side of the flap part (on the side of the back neck muscle of the human body) were measured and shown in the graph. By wearing the hat of the present invention, it shows that the important parts of the human body for heatstroke prevention, particularly from the upper part to the lower part of the back of the head and the upper part of the neck muscles, are effectively cooled and protected against the high-temperature exposure environment caused by the sun's solar radiation.
[0021] Figure 7 is a view showing the usage state of a hat or the like with the structure used in the present invention. In Fig. 7(a), an example of a cap-type hat is shown, and in Fig. 7(b), an example of using it as a zukin worn under a helmet is shown. From one water injection port 1a arranged at the top of the hat body 12, by simply pouring cold water from the PET bottle 71, the head of the wearer of the hat with the configuration of the present invention is covered. Avoiding the size adjustment part 21 of the head circumference size or the size adjustment part 7b2 by a rubber band, the cold water is poured into the water absorption materials 14 and 15, or 3b1 arranged inside the flap part 13 that covers the back of the head to the upper part of the neck muscles. The figure shows that a long-term cooling effect can be obtained by the vaporization action of the internal water absorption material soaked in the water.
[0022] Figure 9 is a perspective view showing an example of a children's flap hat with the structure used in the present invention. As shown in the figure, in the case of a flap hat 91 for children or kindergarten children, an elastic rubber band 92 is often arranged at the rear center of the head circumference size adjustment part. Even in this case, the above-described connecting water channel portion 23 of the configuration of the present invention has the effect that it can be configured while avoiding the rubber band portion 92.
[0023] Furthermore, a third embodiment example regarding the structure of the present invention will be described. FIG. 10(a) is a view of the structure of the present invention seen from the rear, and FIG. 10(b) is a view showing the state when the cross section is cut along the cross section line 101a. In the structure such as a hat used in the present invention, for example, an air gap 18 formed by the water absorbent material 15 and the moisture permeable waterproof cloth 16 at an intermediate position up to the lower end of the flap portion 13 is partially closed by adhesion or sewing thereof to provide a water blocking portion 102. In addition, a drain port 103 is provided at the lower end of the moisture permeable waterproof cloth 16 located below it.
[0024] Thus, the state in which the water introduced from the water injection port 1a flows through the air gap 18 while the water absorbent materials 14 and 15 absorb and store moisture is shown by the water flow direction 105. At this time, the water blocking portion 102 serves to once gather the water flowing from above toward the center of the flap portion so that the central portion of the water absorbent material 15 can be evenly supplied with moisture without omission, and thereby has the effect of planarizing and prolonging the vaporization heat cooling action. Thereafter, the overflowing water is also absorbed by the horizontal end faces of the water absorbent material 15 from both horizontal ends of the water blocking portion 102, and becomes water droplets 106 as excess moisture and starts to drain from the drain port 103 at the lowermost end of the air gap 18, so this can be detected visually or by the touch of the hand.
[0025] In order to obtain the cooling effect by the vaporization heat action of the hat, apron, children's flap hat, etc. having the structure of the present invention, when water is injected from the water injection port, since the drain port 103 is provided by the above structure, after the water absorbent materials 14 and 15 sufficiently absorb and store moisture, as excess moisture, the water droplets 106 and the amount of water leaking from the drain port can be detected visually or by the touch of the hand, and based on this as a reference, for example, in the case of a hat using the cooling structure of the present invention, it is possible to judge and practice how much water should be injected to be optimal. Also, when there is no such drain port 103, one tends to overfill the water, causing a large amount of water to accumulate at the lower end of the flap portion. One can feel the weight of the excess moisture on the back of the neck, or the water-retaining seal formed by adhesion, sewing, etc. around the planar periphery of the front and back, moisture-permeable waterproof fabrics 16 and 17 may break. During hat wearing, the accumulated excess water has nowhere to go and starts to leak ugly from various gaps around the perimeter, leading to an unpleasant feeling and problems. The structure of the present invention has the effect of eliminating this problem.
Industrial Applicability
[0026] Due to recent climate change, there is a strong outcry for the need to address and countermeasures against heat, heat stress, heatstroke, etc. during people's outdoor activities under the severe summer heat. In recent years, with the popularization of the installation of vending machines in the immediate living area, it has become easier to obtain PET bottles filled with cold water at any time and anywhere. For example, a hat, a zukin for a helmet inner, etc. having the structure of the present invention can very easily provide a long-term cooling effect on the part of the human posterior head to the motor nerve of the back of the neck at cold water temperature and by the effect of latent heat of vaporization at any time and anywhere. The wide spread of the present invention will lead to the elimination of people's uneasiness about heat, heat stress, and heatstroke during outdoor activities and outdoor work in midsummer, reduce the physical burden, and greatly expect social and industrial effects by enhancing the efficiency of summer social activities.
