Description

Technical Field

[0001] This invention relates to a cooling structure for cooling hats or headscarves around the head and back of the neck by means of the heat of vaporization of water. Background Technology

[0002] Previously, as a structure that cools by the heat of vaporization of water, the following method was used: a sheet-like absorbent material with considerable thickness that can absorb and store several times its own weight of water was wrapped with an outer and inner fabric that allows water to pass through, and placed on a hat or headscarf or other part that comes into contact with the back of the head or neck. This part was then immersed in water, slightly wrung out, and worn to obtain a cooling sensation.

[0003] In this case, in order for the absorbent material to fully absorb and store water, a water container such as a washbasin or plastic bag is needed. The material is placed in the water for about 1 minute to absorb water, then wrung out slightly to remove excess water before being worn on the head.

[0004] Considering that it would be extremely inconvenient to carry a water container and the water to be poured into it, as shown above, in scenarios such as tennis courts, golf courses, hiking, and jogging during the height of summer, it is impractical.

[0005] Alternatively, water could be dripped onto the aforementioned surface cooling structure, but this would splash around unpleasantly. Moreover, performing this in a moving vehicle on a summer's day, heading to recreational or sports venues, would obviously cause even greater discomfort due to the water splashing in the confined space.

[0006] Patent document 1 discloses a hat with a built-in plastic bag container for storing water. The hat body, with absorbent material embedded in it, is immersed in the water and then placed over the head. The heat of vaporization cools the head, thus helping to prevent heatstroke. However, this method has drawbacks, such as the need to wring out excess water from the hat body after immersing it in water, causing water to splash around, and the inconvenience of cleaning up excess water after use.

[0007] Patent document 2 shows a structure in which a pad made of absorbent material is attached to the part of the hat that contacts the forehead, thereby obtaining a cooling sensation on the forehead through vaporization heat, and the pad is removable. Even in this case, the pad still needs to be immersed in water in a container or rinsed from a tap, thus failing to eliminate the inconvenience of water splashing around.

[0011] Patent Document 2: Japanese Utility Model Registration No. 3130472

[0012] Patent Document 3: Japanese Patent Application Publication No. 2006-328615 Summary of the Invention

[0013] Technical problems to be solved

[0014] The present invention aims to obtain a cooling structure through the action of vaporization heat without immersing or wetting the outer and inner surfaces of the hat body of a hat or headscarf, or without having to keep the water container readily available.

[0015] Solution to the problem

[0016] The structure of the present invention, which is provided on a hat or the like, is configured as follows: a water inlet is provided at the top of the hat body for injecting water from a plastic bottle or cup, etc., and a single or double side and part of the surface of a sheet-like absorbent material is covered inside the hat body with a breathable waterproof cloth, wherein the breathable waterproof cloth has holes as venting windows for vaporization.

[0017] Furthermore, in order to ensure that the injected water flows evenly from top to bottom and left to right within the absorbent material arranged in a planar shape inside the cap, and that the absorbent material can absorb and store water, a gap is provided between the absorbent material and the breathable waterproof fabric to allow water to flow through, serving as a water passage.

[0018] Furthermore, in hats or inner headscarves covering protective caps, such as nursing headscarves for healthcare workers, which have a cap body and a veil connected to the cap body and covering the back of the head and upper neck, a water-connecting section is provided at the connecting part. This water-connecting section bypasses the cap circumference adjustment part of the hat, allowing water injected from the water inlet to flow through the gaps in the cap body and into the absorbent material arranged in a surface on the veil. Moreover, this connecting part is configured as a so-called sleeve-type connection structure: by using a breathable waterproof fabric, the width of the water channel from the cap body is reduced, and the width of the water channel from the veil is increased, forming an overlap. By manufacturing the cap body and the veil separately, they can be efficiently and neatly assembled during the final sewing process.

[0019] In addition, the following structure is provided: a drain outlet is provided at the bottom of the curtain section, which is used to collect and discharge excess water after the water-absorbing material has fully absorbed the water injected from the water inlet, and the appropriate amount of water injected from the water inlet can be determined by detecting the water flowing out from this point.

[0020] The effects of the invention

[0021] The structure of the present invention, which is installed on hats or the like, can uniformly supply water to the wide area of ​​the hat body and the veil covering the head, back of the head and back of the neck, and the surface absorbent material disposed at these connecting parts, by injecting water from a plastic bottle or cup through the water inlet located at the top of the head. This is expected to achieve a rapid cooling effect through the action of vaporization heat.

[0022] Furthermore, in hats or headscarves having the aforementioned hat body and a veil connected to the hat body and covering the back of the head and the upper part of the back of the neck, a cooling effect can also be obtained from the upper hat body to the lower veil through the action of vaporization heat by injecting water from a water inlet located at the top of the head, with only one injection from a single water inlet.

[0023] According to the present invention, it is not necessary to immerse the cap body and the curtain part in water contained in a washbasin or plastic bag container as in the past.

[0024] In recent years, the installation of vending machines selling bottled cold water has become widespread. Bottled cold water can be easily and readily available in lounges of sports clubs such as golf courses and tennis courts, and even on streets and alleys. Especially in the hot summer, athletes often carry it with them during competitions.

[0025] When the carrier wears the hat with the structure of the present invention, even if the cooling effect is reduced due to the evaporation of moisture during a long game, the carrier can immediately and quickly add cold water from the water inlet, thereby quickly restoring and reinforcing the overall cooling effect of both the hat body and the curtain part of the hat, and thus enabling the carrier to restart the game.

[0026] Furthermore, since this water-filling process can be done anytime, anywhere in front of fellow players, it demonstrates the advantages of the hat's ability to maintain a cooling effect for a long time and its effectiveness in preventing heatstroke, making it easier to recommend the hat to friends and other people. Therefore, it is expected to inspire and popularize a revolutionary heatstroke prevention strategy and significantly boost sales of this product.

[0027] Furthermore, in previous children's hoods with cooling functions through vaporization heat, tap water was sprayed onto the absorbent fibers attached to the inside of the hood to make them absorb water. Therefore, when multiple kindergarten children were using the hood, water would splash around the faucet and the children's clothes would get wet.

[0028] When the structure of this invention is used in a children's protective cap, multiple children, under the teacher's command, can simultaneously hold the cap with one hand and a cup containing about 100ml of water with the other. Water can be added only through the water inlet of the structure. Furthermore, when residual water droplets are detected dripping from the drain outlet located at the lower end of the cap, simply instructing them to stop adding water will prevent splashing and ensure that the children's clothes do not get wet. Wearing the cap will also provide a cooling effect from the head to the neck through the action of vaporization heat, which is of great effect on preventing heatstroke and heat exhaustion in children during outdoor activities in the summer.

[0040] Figure 10The diagram shows a drain outlet located at the lower end of a hat or headscarf with the structure of the present invention. Detailed Implementation

[0041] A preferred first embodiment of the hat according to the structure of the present invention will be described in more detail with reference to the accompanying drawings. Figure 1 This is a diagram showing a cross-section of the hat structure employing the present invention.

[0042] The hat 1 consists of a brim 11, a body 12, and a veil 13 located at the rear. Figure 1 The inner cross-section of the portion of the head to the upper neck covered by the hat 1 is also shown.

[0043] A water inlet 1a is provided near the top of the hat body 12 of the hat 1, allowing water to be injected. Furthermore, a first absorbent material 14, which absorbs several times its own weight in water, is arranged in a planar configuration to cover the back of the head on the hat body 12. Similarly, in the curtain section 13, a second absorbent material 15, identical to the aforementioned absorbent material, is arranged in a planar configuration to cover the upper back of the neck.

[0044] Both sides of the first and second absorbent materials 14 and 15 are covered by breathable waterproof fabric 16 and 17, and for example, a planar gap 18 is provided between the outer surface of the breathable waterproof fabric 16 and the surface of the first and second absorbent materials so that water injected from the water inlet 1a can flow and reach the first and second absorbent materials 14 and 15, thereby absorbing the moisture, absorbing moisture and storing water.

[0045] However, although absorbent materials 14 and 15 have been described separately as first and second in the above description, it should be clarified here that even if they are like... Figure 3b The moisture-absorbing material 3b1 shown is continuously configured as an integral structure. Although the effects are different, the present invention still holds true.

[0046] then, Figure 2 This is a diagram showing the back of the hat structure employing the present invention.

[0047] Hats typically have a space for a head circumference adjustment section 21 and an adjustment strap 22 at the center rear of the hat body 12 to fit the person's head circumference.

[0048] In addition, in children's and toddlers' protective caps, such as Figure 9 As shown, a size-adjustable rubber telescopic part 92 is provided at the center of the rear of the cap.

[0049] These size adjustment sections 21 cannot accommodate the absorbent materials 14 and 15, which have a thickness and stiffness (rigidity) many times greater than ordinary fabrics, or the breathable waterproof fabrics 16 and 17 used to form water channels for smooth water flow. Therefore, in order to bypass the size adjustment sections 21 and ensure that the water injected from the inlet is absorbed by the first absorbent material 14 in the cap body and then by the second absorbent material 15 in the lower curtain section, a certain degree of absorbency is required. Figure 2 The structure shown, for example, avoids the size adjustment part and is provided with a connecting water passage 23 for allowing water to flow into the second absorbent material 15 in the curtain part 13.

[0050] Figure 3a This diagram illustrates the combined structure of the multilayer fabrics and components that constitute the present invention.

[0051] Figure 3a The multi-layered fabric and components shown in the diagram, starting from the side facing the head when wearing a hat, are all breathable linings 31 located on the surface of the head, whether for the hat body or the veil. Next, an inner moisture-permeable waterproof fabric 17 with holes for vaporization ventilation is arranged, and the absorbent materials 14 and 15 are attached to its outer side by adhesive or sewing. Then, an outer moisture-permeable waterproof fabric 16 is placed on its outer side, and the inner moisture-permeable waterproof fabric 17 and the outer moisture-permeable waterproof fabric 16 are joined to each other along their outer periphery by adhesive or sewing. Water injected from the water inlet 1a, whether in the hat body 12 or the veil 13, can be absorbed and stored by the absorbent material surfaces 14 and 15, while forming water channels 18 on their surfaces.

[0052] At this time, as Figure 3b As shown, even if the first and second absorbent materials 14 and 15 are continuously and integrally used as absorbent material 3b1 covering the cap body and the curtain, the cooling effect generated by the heat of vaporization in this invention can still be obtained.

[0053] However, by separating the absorbent material into absorbent material 14 for the cap body and absorbent material 15 for the curtain part, the connecting water channel 23 connecting the cap body 12 and the curtain part 13 lacks the thick and stiff feel of the integral absorbent material 3b1. Therefore, by employing a water channel composed only of soft, breathable, and waterproof fabric, such as Figure 8 As shown, from a fashion perspective, the veil 13 can be neatly and easily folded into the hat body 12 for storage, just like wearing a regular hat body, thus achieving a comfortable wearing experience.

[0054] In the figure, 32 is the outer fabric of the cap body 12 and the curtain part 13.

[0055] Furthermore, in this invention, a second embodiment with even better effects will be described.

[0056] In hats with a structure like that of the present invention, the hat body 12 and the veil 13 are typically manufactured separately and then joined together by sewing. To enable efficient and easy assembly, the aforementioned connecting water passage 23 in the hat with the structure of the present invention is configured as follows.

[0057] like Figure 3c As shown, compared with the lateral width of the connecting water channel section 3c1, which is composed of inner and outer breathable waterproof fabrics 17a and 16a assembled on the cap body 12, the lateral width of the connecting water channel section 3c2, which is composed of inner and outer breathable waterproof fabrics 17b and 16b on the curtain side, is wider. Furthermore, when the water channels of the cap body 12 and the curtain section 13 are combined, the connecting water channel section 3c1 on the cap body side is formed in an overlapping manner, for example, by making the connecting water channel section 3c1 on the cap body side longer.

[0058] After the cap body 12 and the curtain part 13 are assembled and manufactured according to this configuration, when they are joined and sewn together on their horizontal lateral perimeter, the connecting water passage part 23 is avoided. The connecting water passage part 23 is formed by inserting a tubular water passage part 3c1 made of breathable waterproof fabric on the cap body side into a tubular water passage part 3c2 of the same slightly larger diameter on the curtain part 13 side, and connecting them in a sleeve manner. Since the connecting water passage parts of the cap body 12 and the curtain part 13 can be avoided to connect the entire lateral circumference, the hat with the structure of the present invention, or such as a protective hat liner scarf, can obtain the connecting water passage part 23 as the connecting part through which the water flows, and at the same time, it can obtain the effect of very effectively simplifying its assembly.

[0059] Figure 4 This is a cross-sectional view showing the water passage portion 23 of the cap employing the present invention.

[0060] This cross section shows along Figure 2 The diagram shows the structure of the aforementioned sleeve type as seen after being cut along section line 2a.

[0061] The description is as follows: The water channel 3c1 on the cap side is connected to the water channel 3c2 on the outer side of the curtain side, which has a larger and wider lateral diameter, by means of a sleeve, avoiding the belt 22 of the size adjustment part 21. On both sides of the belt 22, the water channel 23 is configured to allow the water 41 to flow from the cap side to the curtain side.

[0062] Figure 5 This is a diagram showing the bottom surface of the hat used in this invention.

[0063] The figure shows the configuration structure of vaporization vents 51 and 52 provided on the inner side of the moisture-permeable waterproof fabrics 17a and 17b to promote the vaporization and cooling effect of the water absorbed by the absorbent materials 14 and 15.

[0064] Figure 6 The graph shows the cooling temperature effect of a hat with the structure of the present invention.

[0065] On a sunny summer day around 1 p.m., about 100 ml of cold water (about 12°C) was injected into the water inlet 1a of the hat with the structure of this invention. After 10 minutes, the hat was worn and the wearer spent several hours walking around street corners and parks, watching sports events, etc. During this time, the surface temperature 61 of the top 12 of the hat, the temperature 62 of the inner side of the back of the hat (human side), and the temperature 63 of the inner side of the visor (back of the neck) were measured and displayed in a chart.

[0066] It is evident that by wearing the hat of this invention, effective cooling and protection can be provided for important body parts that are prone to heatstroke, such as the upper and lower back of the head and the upper neck, in response to high-temperature exposure caused by sunlight.

[0067] Figure 7 This diagram illustrates the usage state of a hat or headscarf, etc., having the structure of the present invention.

[0068] Figure 7 (a) shows an example of a baseball cap-style hat. Figure 7 (b) shows an example of the use of a headscarf worn under a protective hat, etc.

[0069] As can be seen, by simply injecting cold water from a plastic bottle 71 into the water inlet 1a located at the top of the hat body 12, the cold water can flow from the hat body 12 covering the head of the wearer of the hat of the present invention, bypassing the head circumference size adjustment part 21 or the size adjustment part 7b2 made of rubber band, into the water-absorbing material 14, 15, or 3b1 located inside the curtain part 13 covering the back of the head and the upper part of the neck. The internal water-absorbing material, wetted by the water, obtains a long-term cooling effect through vaporization.

[0070] Figure 9 This is a perspective view showing an example of a baby hood with the structure of the present invention.

[0071] As shown in the figure, children's and toddlers' protective caps 91 are mostly equipped with a retractable rubber band 92 at the center of the back of the head circumference adjustment part.

[0072] Even under these circumstances, the aforementioned connecting waterway portion 23, constructed according to the present invention, can still achieve the effect of avoiding the rubber belt portion 92.

[0073] Furthermore, a third embodiment of the present invention will be described.

[0074] Figure 10 (a) is a view of the structure of the invention from the rear. Figure 10 (b) is a diagram showing the state of its cross section when it is cut along section line 101a.

[0075] In the structure of hats and the like used in the present invention, for example, at the middle position up to the lower end of the curtain portion 13, the gap 18 formed between the absorbent material 15 and the breathable waterproof fabric 16 is partially closed by bonding or sewing, thereby providing a water-blocking portion 102.

[0076] In addition, a drain outlet 103 is provided at the lower end of the breathable waterproof fabric 16 located below the water-blocking part 102.

[0077] Thus, the water flow direction 105 shows the situation where water injected from the water inlet 1a absorbs and stores water in the absorbent materials 14 and 15 while flowing through the gap 18. At this time, the water-blocking part 102 temporarily gathers the water flowing from above to the center of the curtain part, so that the center of the absorbent material 15 can also receive water supply without leakage and evenly. Thus, the effect of vaporization heat cooling is achieved by making the surface uniform and continuous for a long time.

[0078] Then, the water overflowing from both ends of the water-blocking part 102 in the horizontal direction is also absorbed by both ends of the water-absorbing material 15 in the horizontal direction, and is discharged as excess water from the drain outlet 103 at the lowest end of the gap 18 as water droplets 106. Therefore, these can be perceived by sight or touch.

[0079] In order to obtain the cooling effect of hats, headscarves, and baby hoods with the structure of the present invention through the action of vaporization heat, when water is injected from the water inlet, the water-absorbing materials 14 and 15 are fully absorbed and stored by the drain outlet 103 that conforms to the above structure. The excess water can be perceived by sight or touch, and the amount of water leaking from the drain outlet as water droplets 106 and water volume can be determined. Based on this, for hats and other products using the cooling structure of the present invention, the optimal amount of water to inject can be determined or practiced.

[0080] Furthermore, without the drainage outlet 103, excessive water injection often leads to a large accumulation of water at the lower end of the veil section. This can cause a feeling of excess water weight on the back of the neck or breakage of the water-retaining seal formed by bonding, sewing, or other methods around the inner and outer breathable waterproof fabrics 16 and 17. As a result, excess water accumulates and leaks unsightly from various gaps while wearing the hat, causing discomfort and problems. The structure of the present invention can eliminate this problem.

[0081] Industrial applicability

[0082] In recent years, climate change has led to scorching summers, prompting strong calls to address and take measures to address issues such as heat, heat stress, and heatstroke among people during outdoor activities.

[0083] In recent years, with the installation and widespread use of vending machines in daily life, obtaining plastic bottles filled with cold water has become easy anytime and anywhere.

[0084] Products incorporating the structure of this invention, such as hats and headscarves for protective cap linings, can easily and readily achieve a long-term cooling effect on the area controlling the motor nerves from the back of the head to the back of the neck through the action of cold water temperature and vaporization heat.

[0085] With the widespread adoption of this invention, it is expected to eliminate people's anxieties about the heat, heat stress, and heatstroke during outdoor activities and work in the height of summer, reduce physical burden, and improve the efficiency of social activities in summer, thereby generating significant social and industrial benefits.
