Mode for Carrying Out the Invention

[0020] Next, the terms used in this specification will be briefly explained, and the present invention will be specifically described.

[0021] The terms used in the present invention are selected as generally widely used terms as much as possible while considering the functions in the present invention, but this can change depending on the intention of those skilled in the art, precedents, the emergence of new technologies, etc. Therefore, the terms used in the present invention are not simply the names of terms, but are defined based on the meaning of the terms and the overall content of the present invention.

[0022] When a part of the specification is described as "including" a certain component, unless otherwise stated, this does not exclude other components, but rather means that other components may be included.

[0023] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that they can be easily implemented by a person with ordinary skill in the art to which the present invention pertains. However, the present invention can be embodied in a variety of different forms and is not limited to the embodiments described herein.

[0024] The specific details, including the problems to be solved by this invention, the means of solving those problems, and the effects of the invention, are included in the embodiments and drawings described below. The advantages and features of this invention, as well as the methods for achieving them, will become clear when you refer to the embodiments described in detail below, together with the accompanying drawings.

[0025] The present invention will be described in more detail below with reference to the attached drawings.

[0026] Referring to Figures 1 and 2, a cooling pad for a hat according to a preferred first embodiment of the present invention includes a disc-shaped base portion 100 formed by fusing epithelium 101 and underskin 102, and a foam portion 200 formed protruding from the base portion 100, wherein the foam portion 200 is formed in multiple units and filled with different phase-change materials.

[0027] The base portion 100 is provided in a disc shape and, when worn on the user's head, is formed into a fan shape, and includes a plurality of incisions 100-1 arranged radially with respect to the central portion. The base portion 100 as a whole is manufactured in a rectangular flat plate shape by a pneumatic high-frequency fusion splicer and is formed integrally with the foam portion 200 by a mold during fusion. That is, the base portion 100 has fusion lines 130 formed in the remaining part excluding the foam portion 200 when the epithelium 101 and the subcutaneous tissue 102 are fused, and the shape of the foam portion 200 is variable along the fusion lines 130.

[0028] For example, the multiple foam portions 200 can be formed by chamfering the edges and can be shaped like a semicircle or an arc. That is, the multiple foam portions 200 include multiple semicircular foam portions 200-1 or arc-shaped foam portions 200-2, and when installed inside the hat, they are arranged to surround the user's head. The base portion 100 plays the role of supporting the foam portions 200 by closely adhering to the inner lining of the hat so that the foam portions 200 do not move while in contact with the inner lining of the hat. In this case, the multiple semicircular foam portions 200-1 or arc-shaped foam portions 200-2 are evenly and uniformly arranged across the entire surface of the disc-shaped base portion 100.

[0029] More specifically, the form portion 200 includes a plurality of first forms 201 formed in the central part of the base portion 100, a plurality of second forms 202 formed in a manner that surrounds the first forms 201, a plurality of third forms 203 arranged radially outside the second forms 202 with respect to the central part of the first form 101, and a plurality of fourth forms 204 formed extending radially from the plurality of third forms 203. As an example, the plurality of first forms 201 are provided in a semicircular shape with the fusion splice 130 formed in the central part, and the plurality of second forms 202, third forms 203, and fourth forms 204 can be formed in an arc shape.

[0030] In this process, the plurality of first forms 201, second forms 202, third forms 203, and fourth forms 204 are each filled with a phase change material (PCM). However, the phase change material filled in the plurality of first forms 201 and second forms 202 undergoes a phase change at a lower temperature than the phase change material filled in the plurality of third forms 203 or fourth forms 204.

[0031] More specifically, referring to Table 1 below, the plurality of first forms 201 and second forms 202 are filled with a phase change material that undergoes a phase change at 18°C, and the plurality of third forms 203 and fourth forms 204 are filled with a phase change material that undergoes a phase change at 22°C or a phase change material that undergoes a phase change at 38°C. In other words, the plurality of third forms 203 and fourth forms 204 can each be filled with a phase change material that undergoes a phase change at 22°C. Furthermore, the plurality of third forms 203 can be filled with a phase change material that undergoes a phase change at 22°C, and the plurality of fourth forms 204 can be filled with a phase change material that undergoes a phase change at 28°C. Thus, by filling the plurality of first forms 201 and second forms 202 with a phase-change material that undergoes a phase change at a relatively low temperature, there is an advantage in that the cooling performance to the top of the head, where the most heat is distributed, can be improved. In addition, there is an advantage in that the plurality of third forms 203 and fourth forms 204 can increase the duration for which the cooling performance of the plurality of first forms 201 and second forms 202 can be maintained.

[0032] [Table 1]

[0033] On the other hand, the foam portion 200 is formed in multiple units, each having a different thickness. More specifically, the multiple third foam units 203 are formed to have a smaller thickness than the multiple first foam units 201, second foam units 202, and fourth foam units 204. That is, the multiple first foam units 201 and second foam units 202 are formed to be thicker than the multiple third foam units 203, which has the advantage of maximizing the amount of phase change material for cooling the top of the head and maintaining cooling performance for a longer period. The multiple fourth foam units 204 are formed to have a larger thickness than the multiple third foam units 203, so as to contact the curved outer surface of the head. In other words, the multiple fourth foam units 204 are formed to have the largest thickness relatively, which has the advantage of covering the gaps around the head with the difference in thickness and evenly filling the gaps on the sides of the hat, thereby improving the stable fit of the hat.

[0034] Hereinafter, a cooling band for a hat according to a second embodiment of the present invention will be described in detail with reference to the accompanying drawings. In this embodiment, the fourth foam portion 204 differs from that of the first embodiment in that it is formed to have a greater thickness than the first foam 201 and the second foam 202. For configurations that overlap with this embodiment, refer to the description of the first embodiment.

[0035] Referring to Figures 3 and 4, the plurality of fourth forms 204 are formed to have a greater thickness than the plurality of first forms 201 and second forms 202. Furthermore, the plurality of fourth forms 204 are formed to have a greater thickness than the plurality of third forms 203 so as to contact the outer surface of the curved head. In other words, the plurality of fourth forms 204 are formed to have the relative greatest thickness, which has the advantage of covering the gap around the head with the difference in thickness and evenly filling the gap on the sides of the hat, thereby improving the stable fit of the hat. In addition, a relatively large amount of phase change material is filled, which has the advantage of further increasing the duration for which the cooling performance of the plurality of first forms 201 and second forms 202 can be maintained.

[0036] On the other hand, the plurality of first forms 201 may be formed to have a smaller thickness than the plurality of second forms 202 so that a top button formed at the upper end of the hat can be accommodated. This has the advantage of improving the comfort of wearing the hat.

[0037] On the other hand, the plurality of first forms 201 may be formed to have a thickness greater than or equal to that of the plurality of second forms 201, and to have a greater thickness than the plurality of third forms 203. Similarly, the plurality of fourth forms 204 may be formed to have a thickness greater than or equal to that of the plurality of third forms 203, and to have a thickness greater than or equal to that of the plurality of first forms 201 and second forms 202. In this way, the thicknesses of the plurality of first forms 201, second forms 202, third forms 203, and fourth forms 204 can be configured differently, and the cooling performance of the hat cooling pad of the present invention can be modified as needed.

[0038] In the following, a cooling pad for a hat according to a third embodiment of the present invention will be described in detail with reference to the attached drawings. This embodiment differs from the first embodiment in that the base portion 100 includes a lower base portion 110 and an upper base portion 120 laminated and fused to the lower base portion 110, and the foam portion 200 includes a lower foam portion 210 that protrudes downward from the lower base portion 110 and an upper foam portion 220 that protrudes upward from the upper base portion 120. For configurations that overlap with this embodiment, refer to the description of the first embodiment.

[0039] Referring to Figures 5 and 6, the base portion 100 includes a lower base portion 110 and an upper base portion 120 that is laminated and fused to the lower base portion 110, and the foam portion 200 includes a lower foam portion 210 that protrudes downward from the lower base portion 110 and an upper foam portion 220 that protrudes upward from the upper base portion 120.

[0040] More specifically, two epithelium 101 and two subcutaneous layers 102 are provided, and the upper epithelium 101 and subcutaneous layers 102 are primary fused by a mold to form the upper base portion 120 and a plurality of upper foam portions 220, while the lower epithelium 101 and subcutaneous layers 102 are secondary fused by a mold to form the lower base portion 110 and a plurality of lower foam portions 210. Here, the plurality of lower foam portions 210 and upper foam portions 220 each include the plurality of first forms 201, second forms 202, third forms 203, and fourth forms 204, respectively.

[0041] Furthermore, the multiple upper foam sections 220 and lower foam sections 210 are filled with different phase-change materials. The upper base section 120 and the lower base section 110 are then tertiarily fused together by a mold to join them. That is, the upper base section 120 and the lower base section 110 are fused together to form a flat plate, and the multiple lower foam sections 210 and the upper foam sections 220 are arranged symmetrically to each other. As an example, the primary and secondary fusion are performed by setting the pneumatic high-frequency fusion machine to 5KW, and the tertiary fusion is performed by setting the machine to 13KW to fuse four raw materials together to produce the base section 100.

[0042] Here, the plurality of lower foam sections 210 and upper foam sections 220 are each filled with a phase change material that undergoes a phase change at different temperatures. Referring to Table 1, the phase change material that is filled into the plurality of lower foam sections 210 can be a phase change material that undergoes a phase change at a lower temperature than the phase change material that is filled into the plurality of upper foam sections 220. For example, the plurality of lower foam sections 210 can be filled with a phase change material (PCM, Phase Change Material) that undergoes a phase change at 18°C ​​or below, and the plurality of upper foam sections 220 can be filled with a phase change material that undergoes a phase change at 28°C or above. This allows the user to choose the temperature of either the plurality of lower foam sections 210 or the upper foam section 220, so that the surface of the foam section 200 is positioned below the hat. In other words, it is configured so that the user can selectively adjust or change the temperature as needed.

[0043] Furthermore, although the multiple lower foam sections 210, where the phase change occurs at 18°C ​​or below, are colder than the multiple upper foam sections 220, where the phase change occurs at 28°C or above, their cooling rate is faster. Therefore, the multiple upper foam sections 220 play a role in assisting the cooling temperature and time of the multiple lower foam sections 210.

[0044] For example, at room temperature of 27°C, the multiple upper foam sections 220 increase the time that the multiple lower foam sections 210 maintain their coolness. In other words, the combination of the multiple lower foam sections 210, which undergo a phase change below 18°C, and the multiple upper foam sections 220, which undergo a phase change above 28°C, allows the hat to stay cool for a longer period. To put it another way, if only a single phase-change material that undergoes a phase change below 18°C ​​is filled, the phase-change material will melt at room temperature of 19°C. However, in the present invention, the phase-change material in the multiple upper foam sections 220, which undergoes a phase change above 28°C, absorbs the external temperature and reduces the rate at which the phase-change material in the multiple lower foam sections 210, which undergoes a phase change below 18°C, melts, thus providing the advantage of maintaining coolness for a longer period of time. Furthermore, as can be seen from Figures 7 to 10, sample 3 (200g), which is filled with a larger amount of phase change material, maintains a lower temperature for a longer period of time compared to sample 1 (100g), which is filled with a relatively smaller amount of phase change material.

[0045] As a result, the cooling pad for hats of the present invention has the advantage of being able to be inserted inside a hat to cool the user's head and improve cooling efficiency.

[0046] Thus, the technical configuration of the present invention described above can be implemented in other specific forms by a person skilled in the art to which the present invention belongs without changing the technical idea or essence of the present invention.

[0047] Therefore, the embodiments described above are illustrative in all respects and not limiting, and the scope of the present invention is defined by the claims described below rather than by the detailed description above, and all modified or altered forms derived from the meaning and scope of the claims and their equivalent concepts are included in the scope of the present invention. Furthermore, the embodiments described above can be applied in combination. [Explanation of Symbols]
