[First Embodiment]
Hereinafter, a first embodiment according to the present invention shown in FIG. 1 will be described with reference to the drawings.
In the present specification, the constituent elements included in the higher-order concept and the constituent elements included in the lower-order concept are both given the same or different code numbers as necessary.
In the present invention, as the “joining form”, various methods such as joining by high-frequency pressure bonding, joining by heat fusion, joining by an adhesive, and the like can be adopted.
As shown in FIG. 1, the circulating liquid path member 1 for cooling the body according to the present embodiment is obtained by high-frequency pressure-bonding a pair of elongated high-frequency pressure-bonding sheets 2 and 2 (

joint sheets

2 and 2 in a higher order concept). The liquid passage 3 is formed, and the connection port 6 joined to the joining sheet 2 is provided on the inlet side and the outlet side of the liquid passage 3. As the high-frequency pressure-bonding sheet 2, various synthetic resin sheets capable of high-frequency pressure bonding, for example, synthetic resin sheets such as vinyl chloride resin (PVC) can be employed.
The inlet side and the outlet side are divided for convenience, and the inlet of the liquid pumped from the pump 37 (see FIG. 9) is the inlet side, and the outlet from which the liquid warmed by the body is discharged is the outlet side. Only. That is, it should be noted that the liquid delivery path 38 (see FIG. 9) of the pump 37 (see FIG. 9) is only a point of view to which side of the liquid path 3 is connected.

In the configuration shown in FIG. 1, the connection port 6 has a female pipe 48 protruding from the liquid path 3. However, the connection port 6 can also employ the configuration of the female pipe 48 provided so as to enter the inside of the liquid passage 3. In addition, a double-sided male pipe connector 44 that connects the female pipe 48 and the connecting pipe 45 such as a liquid delivery path and a liquid recovery path on the inlet side and outlet side of the circulating liquid is provided.
The both-side male pipe connector 44 has a structure in which a tapered part 12 on the female pipe 48 side and a tapered part 12 on the connection pipe 45 side are provided at both ends of the pipe body around the pipe body.
In the configuration shown in FIG. 1, the connection port 6 has a disk-shaped connection surface portion 46. The connection port 6 is attached to the liquid path 3 by bonding the upper bonding sheet 2 to the connection port bonding portion 47 of the disk-shaped connection surface portion 46.
Moreover, the liquid path 3 can be formed at low cost by forming the shape pattern of the liquid path 3 by the bonding pattern of the plurality of bonding sheets 2.

[Second Embodiment]
Hereinafter, a first embodiment according to the present invention shown in FIGS. 2 to 3 will be described with reference to the drawings.
In the description of the present embodiment, heat fusion that can be performed at low cost is taken as an example.
As shown in FIG. 2, the circulating liquid path member 1 for body cooling according to the present embodiment heat-bonds a pair of elongated heat-sealing sheets 2 and 2 (

joint sheets

2 and 2 in a higher-order concept). And a spout 6 thermally fused to each of the inlet portion 4 and the outlet portion 5 of the liquid passage 3. As the heat-sealing sheet 2, various synthetic resin sheets that can be heat-sealed, for example, synthetic resin sheets such as polyethylene (PE) can be employed. Usually, the heat-bonding sheet often employs a configuration in which a plurality of synthetic resin layers are laminated in about three layers.

In the configuration of FIG. 2, the liquid passage 3 is formed by forming the edge

joint portions

7 and 7 in which the elongated band-shaped edge portions are heat-sealed leaving the central zone in which the liquid flows in the liquid passage 3. is there. Further, the horizontal width of the liquid passage 3 that is not heat-sealed is set to 2 mm to 15 mm. The reason why the lateral width is limited to this range is to prevent excessive swelling in the vertical direction when the liquid is caused to flow by the pump 37 (see FIG. 9), resulting in a poor flow of the liquid and a decrease in wearing feeling. is there. Moreover, if it is the said range, it is because it is preferable also from the adhesiveness of the liquid path 3 which takes away the temperature of a body, since it will give the preferable contact | adhesion and a feeling of pressure to the extent which swells to the body side.
The spout 6 has a joint surface portion 8 for fusing the heat-sealing sheet 2 and a tube attachment portion 9 provided with a tube portion 11 so as to penetrate the joint surface portion 8. Various shapes such as a quadrangular shape and a semicircular shape can be adopted as the shape of the joint surface portion 8, but it has a horizontally extending region surface that tightly seals the heat sealing sheet 2 so that liquid does not leak.

The pipe portion 11 has a function of communicating the inner liquid passage 3 and the outer connecting pipe (not shown).
In the configuration shown in FIG. 2, the spout 6 is provided with a tube opening 10 provided at a position facing the inside of the liquid passage 3, and communicates with the liquid passage 3 by the tube opening 10.
Around the tube portion 11 protruding from the joint surface portion 8, a tapered portion 12 protruding so as to expand from the tube portion 11 to the outer peripheral side is formed. The tapered portion 12 has a structure that attaches various connection pipes 45 such as a liquid supply pipe, a liquid return pipe, and a connection pipe 15 (see FIG. 5) connected to the spout 6 with one touch, and prevents the connection pipe 45 from coming off. It is the structure for doing. As the tapered shape portion 12, various configurations such as a substantially conical shape (also referred to as a substantially bamboo shoot shape), a substantially spherical shape, and a substantially elliptical spherical shape can be adopted.
By adopting such a tube attachment portion 9 having the tapered portion 12, the attachment and detachment processing is simplified as compared with the configuration of a spout employed in a normal liquid container, such as a threaded coupling of a male screw and a female screw. can do. This configuration is advantageous when the cooling garment is used without connecting the pump, or when only a part of the liquid passage 3 constituting the circulating liquid passage member is replaced.
However, in the present invention, it is not excluded to fix the connecting pipes and the spout 6 with an adhesive or the like.

The spout 6 is made of the same type of synthetic resin that can be easily joined to the joining sheet 2, for example, PE, PVC or the like. Preferably, the same synthetic resin material is used. This is because, if the same synthetic resin material is used, the conditions necessary for joining, for example, the melting temperature and the like are the same, and the joining becomes good.
Moreover, it can also be set as the structure which is easy to heat-seal by employ | adopting the structure which coat | covers the synthetic resin material which is easy to heat-seal | fuse on the joining surface part 8 of the heat-seal | fusion sheet 2 and the spout 6. FIG. For example, the case where the heat sealing | fusion sheet 2 which provided the 2nd synthetic resin layer which is easy to heat-seal | fuse on the surface of at least one side of the 1st synthetic resin layer which is hard to tear and is excellent in a softness | flexibility can be illustrated.
Usually, a configuration having a plurality of heat-sealing sheets 2 is employed.
Similarly, in the spout 6, it is also possible to adopt a configuration in which a synthetic resin layer that is easily heat-sealed is coated on the surface of a durable or flexible synthetic resin substrate.
In addition, the form different from the shape of the convex part 42 formed in the joint surface part 8 described in FIG. 2 and the shape of the convex part 42 formed in the joint surface part 8 described in FIG. 3 is shown. By forming the convex part 42 and the concave part seen from the convex part 42 on the joint surface part 8 so as to be alternately arranged in a direction orthogonal to the direction in which water leaks, there is a possibility of leakage from the liquid from the joint surface part 8 of the spout 6. Can be reduced.
However, a configuration in which the joining sheet 2 is joined to the joining surface portion 8 having a large area that spreads in the horizontal direction without providing the convex portion 42 can exhibit a sufficient sealing effect in practice and can be employed.
