Hat cooling pad

Abstract

Although conventional cooling pads worn on the top of the head provide a cooling effect, their design means that the weight of the pad is concentrated on the top of the head when in use, making the pad feel uncomfortable to wear. In addition, the cooling effect is not easily transmitted to the forehead or temples, limiting the sensation of coolness. [Solution] The conventional problem was solved by forming an outer sheet from a lower end portion that is inserted into an insertion portion consisting of the hat body and a sliding portion provided on the inside of the lower end of the hat body, and a plurality of cells that are partitioned from the lower end upward by a partition portion and are sized to come into contact with the user's forehead and contain a phase change material as a coolant.

Description

[Technical Field]

[0001] The present invention relates to a cooling pad for a hat that is worn inside the hat. [Background technology]

[0002] In recent years, as the impact of global warming increases the importance of preventing heatstroke in the summer, numerous products have been proposed that add cooling functionality to hats worn during outdoor activities. Cooling pads made with PCM (phase change material) have attracted particular attention because they can maintain a cooling effect by changing phases at a constant temperature, and PCM cooling pads that are attached to the top of a hat have been available for some time. However, while these cooling pads can provide a cooling effect, their construction, which is attached to the top of the head, can cause discomfort when worn. Furthermore, the cooling effect is not easily transmitted to the forehead or temples, limiting the sensation of cooling. Therefore, to further enhance the cooling effect, a structure is required in which the cooling pad directly contacts areas that are easily affected by cold, such as the forehead and temples. The forehead has thin skin and a lot of blood flow, making it an area where the cooling effect is easily transmitted, making it an effective cooling point for regulating body temperature and reducing fatigue. In addition, the forehead is prone to sweating and heat buildup, so efficiently cooling this area can be expected to reduce stuffiness and discomfort and lower the perceived temperature. To achieve both a higher cooling effect and a comfortable fit, it is desirable to have a structure in which the cooling pad directly contacts the forehead, but the reality is that conventional technology does not fully consider this point.

[0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to FIGS. [Example]

[0009] The hat cooling pad 1 comprises a lower end 2 inserted into an insertion section 23, which is comprised of a hat body 21 and a sliding section 22 provided inside the lower end of the hat body 21. The lower end 2 is partitioned upward from the lower end 2 by partitions 3, and multiple cells 5, each sized to contact the user's forehead and containing a phase-change material as a coolant 4, are formed by an exterior sheet 6. The hat cooling pad 1 has a curved, band-like shape approximately 25.0 cm wide and 8.9 cm high, and is formed by a flexible exterior sheet 6. The protrusion 11 protruding from the sliding section 22 of the hat cooling pad 1 is designed to be positioned in contact with the user's forehead, allowing the cooling effect generated by the multiple cells 5 containing the coolant 4 to be efficiently transmitted mainly to the forehead, providing a clear and direct sensation of coolness. The hat cooling pad 1 can be transformed into a flat shape or a curved shape that can be worn inside a hat.

[0010] The upper edges 7 of the cells 5 are each formed with a concave portion 8 recessed in an arc shape at the center, and convex portions 9 protruding in an arc shape on both sides of the concave portion 8, and the convex portions are connected to each other.

[0011] The partition 3 has a ventilation hole 10 formed therein.

[0012] The lower end 2 is arc-shaped with a radius of 25.0 cm, following the sliding portion 22 of the hat body 21, so as not to disrupt the hat's silhouette or cause discomfort to the forehead. The user can easily attach the hat cooling pad 1 to the hat body 21 by inserting their hand between the sliding portion 22 of the hat body 21 and the fabric of the hat body 21. It is preferable that the lower end 2 inserted into the sliding portion 22 does not have cells 5 containing coolant 4 for stable attachment of the hat cooling pad 1 to the hat body 21. However, it is also desirable to provide cells 5 at the lower end to cool the forehead over a wide area. In this embodiment, the lower end 2 is formed across the entire width of the hat cooling pad 1, but a portion may be removed as long as the hat cooling pad 1 is held in place by the sliding portion 22. The lower end 2 inserted into the sliding portion 22 may be a separate piece from the hat cooling pad 1, preferably made of a flexible synthetic resin, and attached by adhesive or welding. There is no limitation on the shape of the lower end portion 2. The width and height of the cooling pad 1 for hats do not have to be constant.

[0013] The compartment 3 has a narrow compartment 3a and a wide compartment 3b, and the wide compartment 3b has a ventilation hole 10. The compartment 3 has ten substantially rectangular cells 5 in the lower row, ten substantially rectangular cells 5 in the middle row, and four substantially triangular cells 5 in the upper row, and the compartment 3 spanning the lower and middle rows in the center and the compartment 3 spanning the lower and middle rows in the center are separated by three cells 5 from each other. The compartments 3 spanning the lower and middle rows on both sides are wide compartments 3b, and ventilation holes 10 are formed in the wide compartments 3b.

[0014] Coolant 4 is a PCM, a phase change material. PCM (Phase Change Material) is a general term for materials that absorb or release thermal energy when they change state from solid to liquid or from liquid to solid. While typical ice packs and ice can become too cold in certain areas, PCM can maintain a comfortable cool feeling of 27°C to 29°C, and by pre-cooling it with refrigeration or cold water, it can maintain a constant cool feeling.

[0015] Cell 5 is formed to a depth of approximately 5.0 mm.

[0016] The exterior sheet 6 is made of a transparent polyolefin resin and is durable and flexible, remaining flexible even when the plurality of cells 5 are filled with coolant 4. The exterior sheet 6 is approximately 0.3 mm thick, with the plurality of cells 5 formed in the upper layer 6a that contacts the forehead, and the lower layer 6b that contacts the inner surface of the hat body 21 being formed flat, and the upper layer 6a and the lower layer 6b are joined by thermal welding, for example, so that the coolant 4 does not move between the plurality of cells 5. Note that the lower layer 6b that contacts the inner surface of the hat body 21 does not have to be formed flat.

[0017] The recessed portion 8 is formed in the shape of an arc with a radius of 5.0 cm centered on the center line of the cooling pad 1 for hats, and is capable of adequately cooling the center of the forehead.

[0018] The convex portion 9 is formed so as to be connected to the concave portion 8, and is formed in an arc shape with a radius of 5.0 cm, so that the left and right sides of the forehead can be cooled appropriately.

[0019] The two vents 10 located in the center of the hat cooling pad 1 are 2.0 mm wide and 20.0 mm long, while the four vents located on the left and right are 2.0 mm wide and 19 mm long, and are formed to penetrate the thickness of the wide partition 3b. The reason why the vent in the center is larger than the vents on the left and right is that the center of the forehead is closer to the frontal lobe of the brain than the temporal lobes, and is therefore more susceptible to heat and therefore more susceptible to cooling effects.

[0020] The cooling pad 1 for hats is formed from a flexible exterior sheet 6, and inside it are multiple cells 5 separated by partitions 3. A phase change material (PCM) is sealed inside each cell 5 as a coolant 4, and by pre-cooling it, it can effectively cool the forehead when in use. The upper edge 7 of the cell 5 has a concave portion 8 recessed in an arc shape in the center, and convex portions 9 protruding in arc shapes on both sides. This shape conforms to the curved surface of the forehead, improving the fit and the efficiency of the cooling effect. Furthermore, the lower end 2 of the hat cooling pad 1 is formed in an arc shape, and is attached by being sandwiched between it and the sliding part 22 provided on the inside of the hat body 21. With this configuration, the hat cooling pad 1 is held stably, and the protruding part 11 can be securely brought into contact with the forehead, directly transmitting the cooling effect. Therefore, the cooling pad 1 for a hat in this embodiment can be worn naturally along the shape of the hat body 21, and exhibits an excellent cooling effect while achieving both good adhesion to the forehead and comfort.

[0021] The present embodiment is merely an example, and the configuration of the present invention is not limited to this. The number and shape of the cells, the material of the exterior sheet, the type of PCM, the dimensions of the hat cooling pad, etc. can be changed as appropriate depending on the purpose of use and the type of hat. [Industrial Applicability]

[0022] The cooling pad of the present invention can be attached to headwear to prevent heatstroke and improve comfort for the user when working outdoors, playing sports, engaging in leisure activities, commuting to work or school, etc., and can therefore be widely used in fields such as everyday items, work protective equipment, sports equipment, and outdoor equipment. Furthermore, the present invention can be realized using a relatively simple manufacturing method without using special processing or expensive materials, and mass production is possible by applying existing hat manufacturing processes and cooling material encapsulation techniques. In addition, because the design allows for repeated use, it has high marketability as an environmentally friendly product. Furthermore, by selecting the appropriate temperature range for the PCM used as a coolant, optimal cooling performance can be achieved according to the season and purpose, and products can be developed for different targets, such as children, the elderly, or workers.
