[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A cooling plate for a cap according to the present invention will be described below with reference to an embodiment shown in the drawings. FIGS. 1 and 2 show a cooling plate 1 for a cap according to a first embodiment. Periphery 2 of part 2
a and the peripheral edge 3a of the inner bottom plate portion 3 are airtightly connected to each other, and the inner bottom plate portion 3 facing the head at the time of attachment is formed on a concave curved surface 4 which is recessed from the peripheral edge toward the center. Inner bottom plate 3
A coolant 6 is sealed in a cavity 5 formed between the two. The outer wall plate portion 2 and the inner wall plate portion 3 of the cap body cooling board 1 of the first embodiment are formed of hard plastic and maintain their shapes. Regarding the molding, a desired shape may be obtained by primary processing such as injection molding or blow molding or secondary processing such as vacuum molding, air pressure molding or free blow molding. The connection between the peripheral edge 2a of the outer wall plate portion 2 and the peripheral edge 3a of the inner bottom plate portion 3 may be heat welding, bonding with an adhesive, or integral molding of a material. In addition, in the polymerization by heat welding, an adhesive, or the like, in addition to connecting the illustrated end surfaces, the outer surface or the inner surface of the peripheral edge may be adjusted to a required width (not shown). As the coolant 6, for example, the main component is propylene glycol (manufactured by Asahi Denka Kogyo) or a crosslinked polyamide (manufactured by Mie Chemical Industry). There is a commercial product in which these are stored in a thin thermoplastic bag such as nylon. The coolant 6 is generally put in a freezer for several hours to freeze it, and when the frozen body is thawed and returns to the liquid phase, it exerts a cooling action by removing surrounding heat, and there is a jelly-like product in the frozen body. I do. The coolant 6 requires a certain amount in that it must retain its cooling heat. And when the weight increases, stability is lacking. Therefore, the inner bottom plate portion 3 facing the head at the time of putting on the hat is formed on the concave curved surface 4 which is depressed from the periphery toward the center, and a part of the wearer's head is accommodated inward and the weight is distributed to the periphery. The structure is formed.

Next, a cap cooling plate 7 according to a second embodiment of the cap cooling plate according to the present invention will be described with reference to FIGS. 3, 4, 5 and 6. FIG. The outer wall plate portion 8 and the inner bottom plate portion 9 are formed on the hemispherical surfaces 10 and 11 having a required diameter while leaving the overlapping portions 8a and 9a around, and cooling is provided between the outer wall plate portion 8 and the inner bottom plate portion 9. Agent 6 is added, and polymerized portions 8a and 9a are heat-welded.
The shapes of the hemispheres 10 and 11 are merely examples, and the shape of the flat elliptical shape and the shape of the concave curved surface thereof can be set variously, such as an involute type and a schoroid type, which are not constant radius. In this embodiment, the polyethylene sheet has a thickness of 0.3 mm, a diameter of 154 mm, and a seal margin for heat welding of 7 mm. This material may be a vinyl chloride sheet or another synthetic resin sheet, the thickness of which is suitably 0.1 to 0.4 mm, but is not limited thereto. The size is also an example, and is not limited to the above embodiment.

The coolant 6 of the cooling plate 1 for the cap body of the first embodiment and the cooling plate 7 for the cap body of the second embodiment is a bag-containing coolant 12 enclosed in a middle bag as shown in FIG. May be accommodated as shown in FIG. In particular, a simple package made of a thin sheet material has little effect on the cooling effect and is efficient in encapsulation processing. However, if none of them is put in a bag, the coolant can be distributed evenly to the respective peripheral portions, and the weight distribution is stable. When the coolant 6 and the bagged coolant 12 are curved, they fit well on the wearer's head, but the outer wall plate portion 8 and the inner bottom plate portion 9 of the cap cooling plate 7 of the second embodiment are soft. If it is put in a freezer as it is, it freezes flat if the placed state is flat, and if it is uneven, it freezes unevenly. Therefore, when it is put in a freezer and frozen, it is placed on a curved mold 13 as shown in FIGS. 8 and 9, and frozen in a shape along the curvature of the upper surface 13a. Any number of the cooling plates 7 for caps can be frozen at one time by stacking the molds 13. 8 and 9, reference numeral 13b denotes a through hole, which performs inflow and outflow of cold air and other functions.

Next, a cap cooling plate 14 according to a third embodiment of the cap cooling plate of the present invention will be described with reference to FIGS.
More specifically, a concentric annular concave-convex surface 4a is provided on a concave curved surface 4 which is recessed from the periphery of the inner bottom plate portion 3 of the hard hat cooling plate 1 of the first embodiment toward the center. . Although the concavity and convexity width of the illustrated concentric annular concavo-convex surface 4a is formed almost uniformly, it may not be formed evenly. Since the concentric annular concave-convex surface 4a is for increasing the heat radiation area, the concentric annular concave-convex surface 4a shown in FIGS.
It is not limited to the embodiment shown in FIG.
It may be oval or any other shape. Furthermore, instead of concentric annular irregular surfaces, even irregular surfaces that are simply curved regularly or irregularly, such as triangles, squares, etc., squares, stars, disks, trapezoids, mixed forms of them, and continuous patterns It is free to form irregularities.

Next, a cap cooling panel 15 of a fourth embodiment of the cap cooling panel of the present invention will be described with reference to FIG. The heat insulating material 16 is provided on the outer surface of the plate portion 2. Although not shown, a heat insulating material 16 may be provided on the cap cooling plate 1 of the first embodiment, and although not shown, a sheet-like heat insulating material may be provided without being integrated with the cap cooling plate. In some cases, only that part may be attached. The heat insulating material is effective in preventing heat from escaping upward from the cap cooling plate 15 by itself and simplifying the heat insulating structure on the cap body side. In order to reflect the radiant heat, a metal foil such as an aluminum foil may be provided on the outer surface or the inner surface of the heat insulating material 16.

The embodiment of the cap cooling plate of the present invention is not limited to the above-mentioned cap cooling plates 1, 7, 14, and 15, but may be a baseball cap or a golf cap. Caps, canotias, hats such as hats and bowlers, and helmets can be deployed in hard hats. For example, as shown in FIG. In the arrangement of the cap cooling plate 14 of the embodiment, the cap body 18 of the general cap 17 is used by disposing the inner bottom plate part 3 on the inner ceiling part 18a, above the outer wall plate part 2, and downward. .

Further, as shown in FIG. 14, an inner cap having a heat insulating function will be described in detail for an embodiment in which the cap cooling plate 14 is disposed in the inner top portion 18a of a cap 18 of a general cap 17. A pocket 22 for opening and closing the inner lid 20 of a breathable cloth such as a net cloth with a fastener 21 is provided in the top part 19a of the 19 and is stored in the pocket.

The lower edge of the inner cap 19 is
Is detachably supported by a slide 23 disposed inside the lower edge.

The cap body 1 of the cooling boards 1, 7, 14, 15 for the cap body
8 can be deployed in the inner heaven 18a, etc.
It is not limited to the storage position and structure. Further, as described above, not only general hats but also sports hats to special hats for work such as a protective helmet can be used.

[0021]
