Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-described conventional neck cooling device, when exposed to sunlight during use, the ice melts prematurely, and there is a risk that the cooling effect of the ice does not last long. Further, when a sheet is joined to form the outer bag, there is a risk that the water melted from the ice leaks to the outside through the gap at the joint.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide a method for manufacturing a body cooling device and a body cooling device that can maintain the cooling effect of ice for a long time and ensure waterproof performance so that the water melted from the ice does not leak to the outside.

Means for Solving the Problems

[0006] A method for manufacturing a body cooling device according to the present invention is a method for manufacturing a body cooling device that includes an outer packaging bag having a substantially U-shaped divided into two branches, and ice is contained therein through an ice containing port formed to extend outward from the central outer peripheral portion of the outer packaging bag to cool a part of the body. The bag material of the outer packaging bag with a heat-reflective layer formed on the entire surface is immersed in the waterproof material stock solution in a turned-over state with the heat-reflective layer arranged on the inner side, and a waterproof layer made of the waterproof material stock solution is formed on the entire surface of the turned-over bag material. It has a configuration in which the bag material with the waterproof layer formed is turned inside out from the ice storage opening, the heat-reflective layer is arranged on the outer surface, and the waterproof layer is arranged on the inner surface to form an outer packaging bag.

[0007] According to the above configuration, since the outer packaging bag is manufactured using the bag material with the heat-reflective layer formed on the entire surface, a heat-reflective layer can be formed on the entire outer surface of the outer packaging bag. Also, since the turned-over bag material is immersed in the waterproof material stock solution and a waterproof layer is formed on the entire surface of the bag material, a waterproof layer without gaps can be formed on the entire inner surface of the outer packaging bag.

[0008] The body cooler according to the present invention In a body cooler that includes an outer packaging bag having a substantially U-shaped bifurcated shape and that cools a part of the body by storing ice inside through an ice storage opening formed to extend outward from the central outer peripheral portion of the outer packaging bag, the outer packaging bag has a configuration in which a heat-reflective layer is formed on the entire outer surface and a waterproof layer without gaps is formed on the entire inner surface.

[0009] According to the above configuration, due to the heat-reflective layer formed on the entire outer surface of the outer packaging bag, even when the body cooler is exposed to sunlight during use, heat can be reflected so that the ice inside the outer packaging bag does not melt quickly, and the cooling effect by the ice can be maintained for a long time. Also, due to the waterproof layer formed without gaps on the entire inner surface of the outer packaging bag, the water melted from the ice inside the outer packaging bag can be prevented from leaking to the outside.

Effects of the Invention

[0010] As described above, according to the present invention, there are provided a body cooler and a method for manufacturing the same that can maintain the cooling effect by ice for a long time and can ensure waterproof performance so that the water melted from the ice does not leak to the outside. Therefore, among body coolers using ice, they have high cooling effect and waterproofness and can improve the comfort of users.

Embodiments for Carrying Out the Invention

[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings. This embodiment shows a neck cooling device as an example of a body cooling device that stores ice inside and cools a part of the body. As shown in FIG. 1, the neck cooling device 1 is composed of an outer bag 3 having a substantially U-shape divided into two branches, and an ice storage opening 2 that extends outward from the outer peripheral portion of the center of the U-shape and can be opened at the top. In use, ice is stored inside the outer bag 3 through the ice storage opening 2 and worn around the neck.

[0013] As also shown in FIG. 2, the outer packaging bag 3 has a heat-reflective layer 4 formed on the entire outer surface and a waterproof layer 5 without gaps formed on the entire inner surface. The outer packaging bag 3 itself is made of cloth or soft synthetic resin. In this embodiment, a cloth material sheet 13 is used as the material of the outer packaging bag 3. Note that the material sheet 13 of the outer packaging bag 3 may be a sheet having heat insulation properties by itself, a sheet obtained by laminating a heat insulation sheet on a base cloth sheet, or the like. The heat-reflective layer 4 is a metal layer such as aluminum and is formed by vapor deposition, bonding of a metal film, or the like. Note that the surface of the heat-reflective layer 4 is provided with a protective coating of a transparent material. With this heat-reflective layer 4, heat from sunlight can be reflected, making it difficult for heat to be transmitted to the ice inside the outer packaging bag 3. The waterproof layer 5 is a resin film such as a silicone resin and is formed by an immersion method. With the waterproof layer 5, it is possible to prevent the water melted from the ice contained inside the outer packaging bag 3 from leaking to the outside of the outer packaging bag 3.

[0014] An opening / closing mechanism 6 is provided at the ice storage opening 2 of the outer packaging bag 3. As shown in FIGS. 3(a) and 3(b), the opening / closing mechanism 6 includes two plate-shaped springs 7 disposed opposite to each other around the opening of the ice storage opening 2 and pivotally supported and connected by pins 8 at both ends. The two plate-shaped springs 7 are configured to be displaced to hold the ice storage opening 2 in an open state and a closed state. That is, when the two plate-shaped springs 7 are pulled apart to open the closed ice storage opening 2, the two plate-shaped springs 7 are displaced outward in a V shape, and the ice storage opening 2 is held in the open state (see FIG. 3(a)). Thereby, it is possible to easily put ice into the outer packaging bag 3. Further, when the two plate-shaped springs 7 displaced in a V shape are pushed closer to close the opened ice storage opening 2, the two plate-shaped springs 7 are displaced linearly, and the ice storage opening 2 is held in the closed state (see FIG. 3(b)). Thereby, it is possible to prevent the ice storage opening 2 from opening accidentally and the ice contained in the outer packaging bag 3 from spilling out of the ice storage opening 2.

[0015] Referring again to FIG. 1, a belt member 9 is attached around the opening of the ice receiving port 2. Both ends of the belt member 9 extend outward from the right and left sides around the opening of the ice receiving port 2, and buckles 10a and 10b are attached to the right end and the left end of the belt member 9, respectively. By connecting the left and right buckles 10a and 10b to connect the right end and the left end of the belt member 9, a loop-shaped handle is formed. Thereby, by hanging a finger on the loop-shaped belt member 9, the neck cooler 1 containing ice can be easily held by hand, and the attachment and removal to and from the neck can be easily performed.

[0016] At each tip of the bifurcated portion of the outer bag 3, a string member 12 having a connector 11 is provided. The connector 11 of each string member 12 is composed of a convex part 11a and a concave part 11b. The convex part 11a and the concave part 11b are joined by a concave-convex fit, and the concave-convex fit connection between the convex part 11a and the concave part 11b is configured to be released when a tensile force equal to or greater than a certain value is applied. Thereby, by attaching the neck cooler 1 to the neck and connecting the respective string members 12 with the connectors 11, displacement of the neck cooler 1 can be suppressed. Also, when the neck cooler 1 is pulled, the connection of the connector 11 can be easily released so that the neck is not pulled.

[0017] Next, an example of a manufacturing method of the outer bag 3 constituting the neck cooler 1 will be described. First, a heat-reflective layer 4 is formed on the entire surface of a cloth sheet as a material by vapor deposition or the like. The original material sheet (single-sheet or roll-shaped sheet) with the heat-reflective layer 4 formed on the entire one side is cut into a substantially U shape along the outer shape of the outer bag 3. Two U-shaped material sheets 13 cut into a substantially U shape are used, and the two U-shaped material sheets 13 are overlapped with the surfaces on which the heat-reflective layer 4 is formed facing each other (see FIG. 4(a)), and the outer edge portions excluding the portion that becomes the ice receiving port 2 are sewn and joined to form the bag material 14 of the outer bag 3 (see FIG. 4(b)). This bag material 14 is a bag material 14 in a turned-back state with the heat-reflective layer 4 arranged inside.

[0018] Note that, as the bag material 14 in the turned - over state, two original material sheets each with a heat - reflecting layer 4 formed on the entire one - side surface are overlapped, sewn and joined along the outer shape of the outer bag 3 except for the portion that becomes the ice - receiving opening 2, and then cut into a substantially U - shaped along the outer shape of the outer bag 3 for production.

[0019] Next, the bag material 14 in the turned - over state is immersed in the waterproof material stock solution 15 (see Fig. 4(c)), and then dried to form a waterproof layer 5 made of the waterproof material stock solution 15 on the entire surface of the bag material 14 in the turned - over state. As the waterproof material stock solution 15, for example, a liquid of silicone resin is used.

[0020] Then, the bag material 14 with the waterproof layer 5 formed is turned inside out from the ice - receiving opening 2 (see Fig. 4(d)), the heat - reflecting layer 4 is arranged on the outer surface, and the waterproof layer 5 is arranged on the inner surface, thereby completing the outer bag 3 (see Fig. 4(e)).

[0021] According to the above manufacturing method, since the outer bag 3 is manufactured using the bag material 14 with the heat - reflecting layer 4 formed on the entire surface, the heat - reflecting layer 4 can be formed on the entire outer surface of the outer bag 3. Also, since the bag material 14 in the turned - over state is immersed in the waterproof material stock solution 15 and the waterproof layer 5 is formed on the entire surface of the bag material 14, the waterproof layer 5 without gaps can be formed on the entire inner surface of the outer bag 3 even at the joint portion of the bag material 14.

[0022] According to the neck cooler 1 according to the above embodiment, due to the heat - reflecting layer 4 formed on the entire outer surface of the outer bag 3, even when the neck cooler 1 is exposed to sunlight during use, heat can be reflected so that the ice in the outer bag 3 does not melt quickly, and the cooling effect by ice can be maintained for a long time. Also, due to the waterproof layer 5 formed without gaps on the entire inner surface of the outer bag 3, the water melted from the ice in the outer bag 3 can be prevented from leaking to the outside. Therefore, in the neck cooler 1 using ice, it has a high cooling effect and waterproof property, and can improve the comfort of the user.

[0023] Note that the present invention is not limited to the above - described embodiment, and various changes can be made within the scope of the claims. For example, as shown in FIG. 5, one or more snap buttons 16 may be attached as fixtures to the surfaces (e.g., the same side) of the bifurcated portions on the left and right in the outer bag 3, and the left and right snap buttons 16 may be fastened at arbitrary positions so that the left and right bifurcated portions can be joined at a predetermined position in the longitudinal direction. Thereby, the main body body cooler 1 can be worn so as not to be displaced with respect to a part of the body such as the forehead, arm, or ankle. Also, as shown in FIG. 5, a fastener 17 for sealing the inside of the outer bag 3 may be provided near the ice storage opening 2.
