Abstract

(57) [Summary] [Purpose] Regarding hats used for summer climbing, hiking and other sports, and work in hot places, the purpose is to cool the head by generating heat of vaporization in the hats. To do. [Constitution] The inner surface of the hat is made of a non-water-absorbing material, the outer surface is made of a water-permeable material, and the water retaining material is sandwiched between the outer surface and the inner surface in a multi-layered manner, and a wide perspiration edge is provided around the inner hem of the hat. A hat having an upper half that can be folded inward and outward with the center line of the width dimension of the sweat removal edge as a boundary. [Effect] The heat of vaporization generated by the evaporation of water in the hat has the effect of lowering the temperature of the entire hat and cooling the head, and a wide sweat removal edge is placed inside and outside at the center line of the width dimension. By folding back, it is possible to switch the surface of the sweat-wicking edge that has been warmed up by the body temperature to the cooled surface that has not touched the skin, so that the sensible temperature can be felt more comfortably.

Description

[Detailed description of the device]

[Industrial applications]

 It is a versatile product that can be used as a substitute for towels such as sweat wipes by cooling the head and protecting the head during summer climbing, hiking and other sports and work in hot places. About hats.

[0002]

[Prior art]

 We have seen many applications in the past, such as a hat for hot weather, a hat for cooling the head, and a hat for adjusting the head temperature, and the structure is such that the head of the hat is hollow and cold water is injected into the hollow part. Some of them have a bag-shaped cap and a sponge containing water is inserted into the top of the head. However, all of them are intended to directly cool the head by using cold water or water as a refrigerant, and a definite defect that the cooling capacity is lost if the temperature of the refrigerant itself rises. was there. That is, the principle of the water pillow was applied to the hat as it was.

[0003]

[Problems to be solved by the device]

 The present invention intends to cool the head by allowing a proper amount of water to be contained in the entire hat body as if it were a bath towel, and by generating a heat of vaporization which is a natural phenomenon in the entire hat due to the difference between the water temperature and the outside air temperature. Therefore, the present invention aims to solve the defect that the cooling capacity is lost when the temperature of the refrigerant rises in the prior art.

[0004]

[Means for Solving the Problems]

 According to the present invention, as a means for solving the above-mentioned problems, the entire hat has a flexible multi-layer structure made of a fiber material, a non-water-absorbing material that does not absorb moisture is used on the inner surface of the hat, and water is permeable to the outer surface. In addition to using a soft material, a multi-layered water retaining material is built in between the outer surface and the inner surface of the hat, and a sweat removal edge with a certain width is wide at the hem of the inner surface of the hat that contacts the head. In addition, the folding edge is provided so that the upper half can be folded inward or outward with the center line of the width of the double width as a boundary.

[0005]

[Action]

 When the cap of the present invention is wetted with water and worn, the water-retaining material absorbs water and retains water, but since the inner surface of the hat is a non-water-absorbing material, water does not penetrate and leak to the head. Since the outer surface of the hat uses a water-permeable material that allows water to pass through, the moisture retained in the water-retaining material having a multi-layer structure evaporates, causing heat of vaporization in the hat body, and as a result, the hat. The inside is cooled and the temperature drops, so the head is cooled. Furthermore, when providing a sweat removal edge around the inner hem of the hat, widen the width so that the sweat removal edge can be folded back at the center of the width, and the upper half of the inner side with the center line of this width as the boundary. Alternatively, by providing a foldable edge on the outside, if the temperature of the contact surface between the inner hem of the hat and the head rises and discomfort occurs, the fold edge of the sweat removal edge should be set inside or outside. If you fold it back into place, instead of the sweat removal surface that was in contact with the head when wearing a cap and the temperature was rising, the other wrap edge cooled by the heat of vaporization will come into contact with the head, so the sensible temperature is comfortable. Then, the discomfort is alleviated.

[0006]

【Example】

 To explain the embodiment of the present invention in detail, the inner surface 2 of the cap body 1 that should come into contact with the head is made of a non-water-absorbent material that does not absorb water, and the outer surface 2 that should cover the head is permeable to water. In addition to being composed of the fabric of the above, a multi-layered water-retaining and water-absorbing material 4 such as pile fabric is built in between the outer surface 2 and the inner surface 3, and a wide body is formed around the hem of the inner surface of the hat body 1. A sweat removing edge 5 is provided, and a folding edge 7 is provided so that the upper half of the sweat removing edge 5 can be folded inward or outward with a center line 6 of the width dimension of the wide sweat removing edge 5 as a boundary.

[0007]

[Effect of device]

 If the hat is immersed in water before or during use, the water penetrates the inside through the cloth, which is the water permeable material on the outer surface of the hat body, and the water is retained in the built-in water retaining material. If the cap in this state is covered, the water contained in the water retention material evaporates through the cloth, which is a water permeable material, depending on the outside temperature, and heat of vaporization is generated according to the law of nature. The effect of cooling the head through the cloth, which is a non-water-absorbent material, on the inner surface of the hat occurs while lowering the temperature to maintain a constant temperature. In addition, by making the inner surface of the hat non-water-absorbent, there is no risk of water penetrating from the built-in water retaining material to wet the head. Further, as shown in FIGS. 2 and 3, by providing a folding edge capable of folding the upper half of the wide sweat collecting edge inward or outward from the center line, the sweat collecting edge warmed by contact with the head is provided. Inside the hat by folding back the folded edge and exposing the other side that was not in contact with the head, that is, the cooled surface in contact with the inner surface of the hat, and contacting it with the forehead and head. The sensible temperature of is reduced and the discomfort when wearing a hat is further reduced.

The conventional cap that cools the head by using the heat of vaporization does not lose its cooling capacity when the temperature of the water refrigerant body stored in the cap rises like the conventional water pillow method, and is stable. Not only is the cooling effect obtained, but the cooling sensation can be further enhanced by operating the folding edge provided on the sweat removal edge.
