In the present invention, assuming the bending line 26 of the liquid passage 3 having the fusion portion 14 and the flow path portion 16, the fusion portion 14 and the flow on the bending line 26 are assumed. The fusion-bonded portion 16 is disposed flat so that the passage portions 16 are present together (claim 6).
With this configuration, it is possible to provide a cooling garment or the like that can be cooled even when the movement of the body is large because the liquid flows into the flow path even when bent at least with respect to the assumed bending line.

The pressing die used in the fusion bonding portion forming step and the pressing die used in the edge portion bonding portion forming step may be separately configured. Moreover, although it can be cheaply manufactured that a fusion-fusion-part formation process and an edge part junction-part formation process are performed simultaneously, the case where it carries out by shifting time is included.
According to this configuration, since the formation process of the fusion bond and the formation process of the edge joint can be performed simultaneously or continuously by the pressing process of the predetermined pressing die, the manufacturing cost can be largely reduced.

In the present invention, at least one of the concavo-convex sheet 2 having a width or a length larger than the width L or the length of the liquid path 3 is employed to perform the fusion portion forming step, and the straight line of the flow path portion 16 The liquid passage 3 having the flow passage portion 16 is formed so as to expand in at least one of the sheet upward direction and the downward direction than the length S (claim 14).

First Embodiment
Hereinafter, a first embodiment according to the present invention shown in FIGS. 1 to 3 will be described based on the drawings. In the description of the present embodiment, heat fusion which can be implemented inexpensively as a means for joining sheets will be described as an example.
As shown in FIG. 1, the liquid passage member 1 for body cooling according to the present embodiment heat-seals the uneven sheet 2 formed of a pair of elongated heat-sealable sheets (joining sheets in a broad sense) And the spout 6 as the connection port 6 heat-sealed to each of the inlet 4 and the outlet 5 of the liquid passage 3. As the heat fusion sheet 2, various synthetic resin sheets capable of heat fusion, for example, synthetic resin sheets such as polyethylene (PE) can be adopted. In general, the heat fusible sheet is often configured by laminating a plurality of synthetic resin layers with about 2 to 3 layers together with a strong synthetic resin.

Next, the formation of the liquid path by the concavo-convex sheet 2 which is the most significant feature of the present embodiment will be described.
The fluid path member 1 for body cooling is a flat liquid conducting member in which a plurality of sheets including at least one concavo-convex sheet 2 on which small concavities and convexities are formed are overlapped. It is preferable that both the upper side sheet and the lower side sheet be the uneven sheet 2 or 2, but the configuration of the flat sheet on one side and the uneven sheet on the other side can be sufficiently adopted in practice.
Further, the liquid passage member 1 is a sheet that spreads in a planar manner, and is not fused between the fused portion 14 and the fused portion 14 which are formed by fusing a part of the sheet in a spaced apart manner in plan. And a channel portion 16 formed with 15 left. The flow passage portion 16 is a passage through which the cooling liquid flows (see, for example, FIG. 5A). The overall shape of the fluid path member 1 is not limited to the linear shape shown in FIG. 1, but the overall shape of the fluid path member 1 is appropriately designed to conform to the shape of each part of the body such as for back, head or arm. (See FIG. 4 described later).
In addition, in FIG. 1, the structure of the fusion | fusion part 14, the flow-path part 16, and the unevenness | corrugation 15 is demonstrated in the state which cut out a part of liquid path 3 for simplicity. In practice, the fusion bonded portion 14, the flow path portion 16 and the unevenness 15 are formed over the entire surface of the liquid path 3.
In the case where the fluid passage member 1 is formed thin and the emphasis is on reducing the amount of cooling water and cooling quickly and improving comfort, the thickness of the fluid passage member 1 is reduced to about 1 mm to 3 mm. It will also be possible. The height setting of the unevenness | corrugation at that time can also be 0.05 mm-1 mm, if an example is given, for example.

Furthermore, in the configuration of FIG. 1, the liquid passage 3 is formed by forming the edge joint portions 7 and 7 in which the narrow band-shaped edges are heat-sealed, leaving the central zone where the liquid flows in the liquid passage 3. It is
In addition, the spout 6 has a joint surface 8 for fusing the heat-fusion sheet 2 and a pipe mounting portion 9 provided with a pipe 11 so as to penetrate the joint surface 8. Although various shapes such as a square shape and a semicircular shape can be adopted as the shape of the bonding surface portion 8, any configuration has a horizontally spread area surface that tightly seals the heat fusible sheet 2 so that the liquid does not leak. Have.

In the configuration shown in FIG. 1, the spout 6 is provided with a pipe port 10 provided at a position facing the inside of the liquid path 3, and the spout 6 is in communication with the liquid path 3 by the pipe port 10.
A tapered portion 12 is formed around the pipe portion 11 protruding from the joint surface portion 8 so as to expand from the pipe portion 11 to the outer peripheral side. The tapered portion 12 has a structure for suppressing attachment or detachment of various connection pipes such as a liquid supply pipe, a liquid return pipe, and a connection pipe connected to the spout 6 with one touch. As the tapered 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 the pipe attachment portion 9 having such a tapered portion 12, the attachment / detachment process is simplified as compared with the configuration of the spout employed in a normal liquid container, such as a screw connection of an external thread and an internal thread. can do. This configuration is advantageous in the case where only a part of the fluid passages 3 constituting the fluid passage member is replaced when the fluid passage member is broken.
The spout 6 is made of the same kind of synthetic resin that is easy to bond to the uneven sheet 2, for example, PE, PVC or the like. Preferably, they are made of the same synthetic resin material. If it is the same synthetic resin material, the conditions necessary for bonding, for example, the melting temperature, etc. are the same, and the bonding becomes good.

Hereinafter, an example of the process of making the liquid passage 3 according to the present embodiment by superposing a plurality of sheets including at least one uneven sheet 2 in which the small unevenness 15 is formed will be described.
First, as shown in FIGS. 2 (A) and 2 (B), two flat sheets 17 and 17 made of, for example, synthetic resin are prepared, and as shown in FIGS. 2 (C) and 2 (D), The uneven sheet 2 is obtained by the method. The height and width of the unevenness 15 are not particularly limited as long as the liquid flows well when adopted for cooling clothes and the like. As an example, the height H of the unevenness may be in the range of 0.05 mm to 10 mm, and more preferably, the height H may be in the range of 0.5 mm to 5 mm.
Also, the width W is in the range of 0.05 mm to 10 mm,
More preferably, the width W may be in the range of 0.5 mm to 5 mm.
Next, as shown in FIG. 3A, the concave and convex sheets 2 and 2 are sandwiched and fused by a fusion part pressing die 18 having a predetermined fusion pattern in a planar manner.
And as shown to FIG. 3 (B) (C), the flow-path part 16 which has the melt | fusion part 14 spaced apart and arrange | positioned planarly and having the uneven part 15 in-between is formed.

In the configuration shown in FIGS. 1 to 3, the fusion bonding pattern of the fusion bonding part 14 has a configuration in which circular fusion parts are arranged at regular intervals in the longitudinal direction and the lateral direction. The arrangement interval between the fusion-bonded portions 14 is not particularly limited as long as the liquid flows and the body can be cooled well.
Generally speaking, the concept of the configuration of the fusion bond 14 is
(1) It is possible to secure the flow rate of the liquid pumped by a pump or the like, and set in the flow path portion 16 having an area large enough to allow sufficient cooling.
(2) When flowing the liquid at a predetermined pressure, the size is set such that the fusion bond 14 does not peel off due to the pressure of the liquid or the movement of the body,
(3) The shape of the fused portion 14 is set such that the liquid flows in all possible directions such as the longitudinal direction, the lateral direction, and the oblique direction.
The balance is set taking into consideration the three points. Generally speaking, a configuration in which a circle, an ellipse, and a polygon are separately disposed on a plane is expected to often meet the above two requirements.

  According to the configuration of the present embodiment, by providing the fusion-bonded portions in a planar manner, expansion of the liquid path 3 can be suppressed even in a state where pressure is applied to the liquid, and the contact area to the body can be increased. . In addition, since it is formed of the uneven sheet 2, it can be formed thin if necessary, so that the comfort is improved and the amount of water required for cooling can be reduced. As the amount of cooling water per unit area can be reduced, the body can be cooled immediately. In addition, since the fusion-bonded portion 14 is formed by fusion bonding in a separated manner in a plane, there is an advantage that the liquid flow path can be secured also in the horizontal, vertical and diagonal directions. Moreover, even if the liquid passage 3 is bent according to the movement of the body, the small unevenness 15 prevents the flow passage portion 3 from being closed. In addition, since the formation of the uneven sheet 2 in which the small unevenness 15 is formed and the formation of the fusion-bonded portion 14 can be easily performed, the manufacturing cost can be significantly reduced.

Next, as shown in FIG. 4, a device in the case of forming the liquid passage members for the head and the clothes using the above-mentioned liquid passage members will be described.
As shown in FIG. 4, the liquid passage 3 employed in the cooling clothes 28 of this embodiment is provided with a branch portion 22 for separating the meandering portion 24 from the inner side of the liquid passage 3 and adjacent from the outer edge side of the liquid passage 3. It is set as the structure provided with the cut part 23 which isolate | separates the meander part 24 which fits. By providing the notches 23, the meanders 24 can be relatively freely deformed relative to the meanders 24 adjacent to each other.
Specifically, the branch portions 22 are provided in a laterally symmetrical shape so as to extend in the left-right direction (width direction) from the central region 21 extending in the up-down direction (longitudinal direction). Further, the branch portion 22 is formed to extend from the inside along a substantially small U-shaped line. As the shape of the meandering portion 24, not only the substantially U shape, but also a substantially J shape, a substantially Δ shape, or the like can be adopted to appropriately increase the length of the liquid path 3.
On the other hand, the incisions 23 are set to an incision depth such that most of the respective meanders 24 can be deformed in the horizontal and vertical directions.

  With the configuration in which the notches 23 are provided in the meandering portion 24, even in the case where the liquid passage member 1 covering the head is formed by the plane pattern as shown in FIG. 3A, the meandering portions 24 are adjacent to each other For 24.24, it can be freely deformed from a narrow width to a wide width in the horizontal direction. The width of the central region 21 can also be deformed from narrow to wide in the horizontal direction.

It is also possible to manufacture the patterns of the edge joints 7 and 7 and the fusion bond 14 of the meandering liquid path 3 continuously in time, which makes it possible to significantly reduce the manufacturing cost. . That is, the entire shape of the liquid passage 3 is processed like a pattern of clothes, and the edge joining portions 7 are fused to form the liquid passage 3 and the fused part 14 in the liquid passage 3 together. is there. As one form thereof, a method can be exemplified in which a fused portion is first made with a mold for producing the fused portion 14 and then the edges are fused with a mold for producing the edge joint portions 7. It is also possible to integrate the mold for forming the fusion bond 14 and the mold for forming the edge joint 7.
According to this method, the liquid passage member 1 can be easily manufactured simply by fusing the connection port 6 to the inlet and the outlet of the liquid passage manufactured by the above process.

Second Embodiment
As shown in FIG. 5, various shapes can be adopted for the fusion bond pattern. In this case, the fusion bond pattern is formed such that the flow path portion 16 having the unevenness 15 is present even if it is bent with respect to the assumed bending assumed line 26. As shown in FIG. 5 (c), although it is conceivable to form the fusion-bonded portion 14 with curvilinear portions arranged apart from each other, it is also possible to form the fused portion 14 as shown in FIG. 5 (b). In order to generate the flow of the liquid, it is preferable that in the longitudinal direction, the lateral direction, and the oblique direction, surface portions of a certain size be arranged apart.
In other words, the fusion-bonded portions 14 of a predetermined size are set apart in a planar manner so that the liquid flows in the longitudinal direction, the lateral direction, and the oblique direction. By this configuration, for example, it is possible to diffuse the liquid in a free direction as shown by the flow line 27 in FIG. 5 (A).

Third Embodiment
As shown in FIG. 6, this embodiment features two points.
First, the first point is that the sheet on one side is composed of the flat sheet 17 and the other sheet is the uneven sheet 2.
The second point is characterized in that the convex portion 15 of the asperity 15 is formed by either the printing convex portion or the blowing convex portion. Also in the present embodiment, it is possible to manufacture in a similar manner only by adopting the concavo-convex sheet 2 used for forming the liquid path member 1 as the printing convex part sheet and the blowing convex part sheet.

Fourth Embodiment

As shown in FIG. 7A, at least one concavo-convex sheet 2 having a full width L of the liquid path, or a longitudinal length not shown, and a longer length is prepared. Then, when the fusion bonded portion 14 is formed as shown in FIG. 7 (B), in FIG. 7, the flow path portion 16 is filled with the liquid for the wider width and length of the upper concavo-convex sheet 2 and the lower concavo-convex sheet 2. When flowing, the swelling R (indicated by R in FIG. 7) can be enlarged. In addition, in this production, it is necessary to perform the fusion process carefully so that the wide upper and lower concavo-convex sheet 2 and the lower concavo-convex sheet 2 are not folded into the fused part 14 and fused. As a method thereof, a method is conceivable in which the fusion treatment is performed in a state in which the upper and lower concavo-convex sheets 2 are inflated by pressurizing air.
In addition, only the sheet | seat 2 of one side of the upper side uneven | corrugated sheet 2 and the lower side uneven | corrugated sheet | seat 2 may be largely set to the width direction and the length direction, and you may comprise in a wide sheet | seat and a longitudinally long sheet.
FIG. 7C is a schematic enlarged cross-sectional view, and shows the state of the flow path portion 16 which is expanded upward and downward in the state in which the liquid flows.
The magnification of the configuration in which the swelling R is larger as shown in FIG. 7 (B) (C) as compared with the configuration in which the flow path 16 has a smaller expansion as shown in FIG. Will vary depending on the application and location of the cooling member employed.
