Specifically, the cold storage material 30 is made by folding a belt-shaped resin film in two at the center in the width direction, welding the entire overlapping outer edge portions, and covering the entire width direction at a plurality of locations in the longitudinal direction. By welding together, a structure having a plurality of bag portions 31 surrounded by the welded portions on three sides is formed.

The plurality of bag portions 31 form a rectangular shape elongated in the longitudinal direction of the cold storage material 30 and are filled with refrigerant. The filling amount of refrigerant in each bag portion 31 is such that each bag portion 31 is maintained in a flat shape. Moreover, since each bag portion 31 of the cold storage material 30 has a flat shape, as shown in FIG.

As shown in FIG. 2, one cold storage material 30 is provided with an even number (for example, 4, 6, 8, or 10) of bag portions 31, and adjacent bag portions 31 are welded to each other. The number of the portions 32 is one less than the number of the bag portions 31, and one of them is located in the center of the entire cold storage material 30 in the longitudinal direction. The total length of each connecting portion 32 (that is, the distance between adjacent bag portions 31) and the total length of each pair of welded portions 33 at both ends of the cold storage material 30 are 1/1 of the total length of the bag portion 31. It is about 8 to 1/4. Then, the end portions of all the adjacent bag portions 31 are overlapped with each other, and the welded portions 33 at both ends of the cold storage material 30 are overlapped with the end portions of the bag portions 31 (hereinafter, this state is referred to as a "partially overlapped state"). , see Fig. 4).

As the refrigerant of the cold storage material 30 of the present embodiment, for example, a gel-like refrigerant made of a mixture containing water and water-absorbing resin can be used.

The second connecting portion 23 and its hook-and-loop fastener 23M are substantially square, while the first connecting portion 22 and its hook-and-loop fastener 22M extend in the longitudinal direction of the cover 20 as a whole. As a result, the belt-shaped cooling device 10, for example, has the second surface 92 of the cover 20 applied to the rear part of the neck, and the second connection part 23 is placed at an arbitrary position in the longitudinal direction of the first connection part 22 on the front side of the neck. It is possible to adjust the size of the rings of the band-shaped cooling device 10 by stacking them so that the two-sided fasteners 22M and 23M are engaged without being exposed (see FIG. 1).

As shown in FIG. 2 , the cold storage material accommodating portion 21 has a belt-like bag structure for accommodating the cold storage material 30 . The inlet/outlet 24 through which the cold storage material 30 is taken in and out is arranged in the middle of the cold storage material accommodating portion 21 in the longitudinal direction. Specifically, as shown in FIG. 3, the cover 20 has a first belt-like fabric 25 extending along the entire longitudinal direction of the cover 20 on the side of the first surface 91 and a longitudinal portion of the cover 20 on the side of the second surface 92 . A second strip-like fabric 26 extending from one end in the longitudinal direction to an intermediate position, and a third strip-like fabric 27 extending from the other end in the longitudinal direction of the cover 20 to an intermediate position on the second surface 92 side. Then, the second and third belt-like fabrics 26 and 27 are superimposed and sewn on the outer edge of the first belt-like cloth 25 to form a bag body. A doorway 24 of the bag is formed between the fabrics 26 and 27. - 特許庁Then, the bag body is turned inside out so that the sewn part is accommodated inside, and furthermore, the first belt-like fabric 25 is attached to the first belt-like fabric 25 over the entire width direction at positions near one end and near the other end in the longitudinal direction of the bag body. By overlapping and sewing the third belt-like fabrics 26 and 27, as shown in FIG. and becomes the cover 20 .

The second belt-shaped cloth 26 forms a flap 28 at the end opposite to the first connecting portion 22, and the entire edge portion excluding the flap 28 is sewn to the outer edge of the first belt-shaped cloth 25 as described above. It is On the other hand, the third belt-like cloth 27 is sewn to the first belt-like cloth 25 along the entire edge except for the tip portion on the side opposite to the second connecting portion 23 . The base end of the flap 28 of the second strip 26 forms one lateral opening edge 24A of the doorway 24, while the tip of the third strip 27 forms the other lateral edge of the doorway 24. It forms an opening edge 24B.

The center of the entrance/exit 24 in the horizontal direction (that is, the center between the opening edges 24A and 24B) is positioned substantially at the longitudinal center of the cold storage material accommodating portion 21, and the entire length of the entrance/exit 24 in the horizontal direction (that is, the opening edge 24A). , 24B) is about ⅓ to ⅔ of the total length of the bag portion 31 of the cold storage material 30 . Also, the flap 28 is longer than the entire length of the doorway 24 in the horizontal direction so that the tip can be inserted inside the other opening edge 24B of the doorway 24 (see FIG. 1).

Further, the inside of the cold storage material accommodating portion 21 is sized to accommodate the cold storage material 30 in the partially overlapped state described above. Then, as shown in FIG. 4, when the cold storage material 30 is partially overlapped and accommodated in the cold storage material accommodating portion 21, the overlapped portion of the bag portions 31 at the center of the cold storage material 30 in the longitudinal direction of the inlet/outlet 24 is closed. Located in the horizontal center.

The strip-shaped cooling device 10 of the present embodiment is provided with a strip-shaped heat insulating sheet 40 that can be inserted into the cold storage material accommodating portion 21 as necessary. As shown in FIG. 2 , the strip-shaped heat insulating sheet 40 has a bag structure in which a strip-shaped foamed resin sheet 41 is covered with a resin film 42 . The resin film 42 is made of, for example, a polyethylene film, and has a smoother surface than the foamed resin sheet 41 . As a result, the band-shaped heat insulating sheet 40 can be smoothly inserted into the cold storage material accommodating portion 21 .

The configuration of the belt-shaped cooling tool 10 of the present embodiment has been described above. Next, the action and effect of the cooling strip 10 of the present embodiment will be described by taking as an example the case where the cooling strip 10 of the present embodiment is used by being wrapped around the neck.

To use the cooling strip 10, the cold storage material 30 is taken out from the cooling strip 10 and cooled in advance in a freezer. When used, the cold storage material 30 is stored in the cold storage material storage portion 21 of the cover 20 . When the cooling strip 10 is to be used for a long time, the heat insulating strip 40 is stored in the cold storage material storage portion 21 prior to the cold storage material 30 . Specifically, after inserting half of the strip-shaped heat insulating sheet 40 from the opening edge 24A of the doorway 24, the strip-shaped heat insulating sheet 40 is bent into a U shape and the other half is inserted from the opening edge 24B. Also, a plurality of strip-shaped heat insulating sheets 40 may be accommodated in the cold storage material accommodating portion 21 in a similar manner. Thereby, the cold insulation effect in the cold storage material accommodation part 21 improves.

Although the strip-shaped heat insulating sheet 40 may be left stored in the cold storage material storage section 21, the cover 20 can be washed by removing the cold storage material 30 and the strip-shaped heat insulation sheet 40 from the cold storage material storage section 21. Become.

Next, in order to accommodate the cold storage material 30 in the cold storage material accommodating portion 21, for example, the cover 20 is bent in a U shape so that the inlet/outlet 24 is on the outside, and the cold storage material 30 is folded so that the central communication portion 32 in the longitudinal direction is bent. One end of the cold storage material 30 is inserted from the opening edge 24A of the entrance/exit 24, and the other end is inserted from the opening edge 24B. At that time, the welded portions 33 at both ends of the cold storage material 30 are folded over the ends of the bag portions 31, and the ends of the adjacent bag portions 31 are overlapped and inserted. As a result, the end of the last bag portion 31 protrudes from both opening edges 24A and 24B of the entrance/exit 24, so that the cover 20 and the cold storage material 30 are extended linearly, and the end of the bag portion 31 on one side thereof is extended. part is superimposed on the end of the bag part 31 on the other side and stored in the cold storage material accommodating part 21 .

Although the cold storage material 30 may be accommodated in the cold storage material accommodating portion 21 without accommodating the heat insulating sheet 40 in the cold storage material accommodating portion 21, the band-shaped heat insulating sheet 40 is inserted into the cold storage material accommodating portion 21 first. As a result, the insertion resistance of the cold storage material 30 into the cold storage material accommodating portion 21 is reduced, and the work of inserting the cold storage material 30 becomes easier. Alternatively, the cold storage material 30 may be partially overlapped and packaged integrally with the band-shaped heat insulating sheet 40 with a resin film or the like, and the cold storage material 30 and the band-shaped heat insulating sheet 40 may be inserted together into the cold storage material accommodating portion 21 . .

After storing the cold storage material 30 , an additional strip-shaped heat insulating sheet 40 is placed behind the cold storage material 30 as necessary, and the doorway 24 is closed with the flap 28 .

In order to wrap the belt-shaped cooling device 10 around the neck, the entrance 24 portion is applied to the rear portion of the neck, and the first connecting portion 22 is wound so as to overlap the second connecting portion 23 from the outside, and the hook-and-loop fasteners 22M and 23M are connected. Just do it. In order to take out the cold storage material 30 from the cold storage material accommodating portion 21 after the use of the belt-shaped cooling device 10, the cover 20 is bent in a U shape around the entrance 24, and the cold storage material 30 is removed from the cold storage material accommodating portion 21. Take it out and cool the cold storage material 30 in a freezer.

As described above, in the belt-shaped cooling device 10 of the present embodiment, the inlet/outlet 24 for inserting and removing the cold storage material 30 is arranged at a midway position (more specifically, substantially at the center) in the longitudinal direction of the cold storage material accommodating portion 21 . Therefore, the length for inserting the cold storage material 30 from the entrance 24 can be shortened, and the cold storage material 30 can be easily taken in and out as compared with the conventional one having the entrance at the end of the cold storage material accommodating part 21.例文帳に追加

In addition, since the cold storage material 30 is accommodated in the cold storage material accommodation portion 21 in a partially overlapped state, the bag portions 31 are arranged in a continuous state, and the entire area of the cold storage material accommodation portion 21 can be cooled. Furthermore, since the cool storage material accommodating portion 21 has a length that can accommodate the partially overlapped cool storage material 30, the bias of the cool storage material 30 in the cool storage material accommodating portion 21 can be reduced.

Furthermore, by inserting the cold storage material 30 in a state in which the strip-shaped heat insulating sheet 40 is accommodated first, the cold storage material 30 can be inserted more easily, and the heat dissipation of the cold storage material 30 can be suppressed. In addition, by inserting the band-shaped heat insulating sheet 40 after the cold storage material 30 is accommodated, the cold storage material 30 is less likely to jump out of the cold storage material accommodating portion 21, and the cooling effect on the neck can be alleviated. It is possible to extend.
