Description

  The present invention relates to a cooling scarf, and in particular, to a cooling scarf that can cool and cool the periphery of a neck for a long time.

  Traditionally, in hot weather such as summer, the area around the neck gets hot, especially when you play sports for a long time, the area around the neck gets hot and sweat flows. The method of wrapping around the neck was taken. However, the method of wrapping towels and handkerchiefs in water and wrapping them around the neck warmed the hot summer sun and body temperature, and the water immediately evaporated, so the cooling effect was not sustained.

  Therefore, in recent years, a cooling neckband has been devised. (For example, refer to Patent Document 1). The cooling neckband is composed of a band-shaped main body formed by folding a water-permeable sheet in the longitudinal direction, a bag portion formed by partitioning the middle of the band-shaped main body with a partition, and a water absorption housed in the bag portion. It consists of a polymer.

  The cooling neckband is formed by folding a belt-shaped water-permeable sheet into two and stitching the edges together with a seam to form a belt-shaped main body, and in the middle of the main body is a bag portion partitioned by the seam. is there. The bag portion is further partitioned by a seam to form two compartments. In each of the two compartments, a large number of particulate water-absorbing polymers are distributed and stored at an equal density.

  In this configuration, the water-permeable bag portion is permeable to water and has an effect of facilitating water absorption from the outside by the water-absorbing polymer in the bag portion. The water-absorbing polymer has an action of quickly making itself gel by a high water-absorbing action. Since the gel-like water-absorbing polymer does not cause convection of water, it has a cold-retaining action that keeps the cooling state long once cooled. The plurality of compartments containing the water-absorbing polymer have an action of maintaining the water-absorbing polymer density evenly.

  DESCRIPTION OF EMBODIMENTS Preferred embodiments (examples) of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a front view of a cooling scarf according to an embodiment of the present invention. The cooling scarf 10 has a strip-shaped main body 11 formed using a water-permeable sheet and two bag portions 12 and 13 formed on the strip-shaped main body 11. A water-absorbing polymer 25 (see FIG. 3) is accommodated in the bag portions 12 and 13. Moreover, the cooling scarf 10 has band-shaped end portions 18 and 19 sewn at both ends of the band-shaped main body 11 so as to close the openings 14, 15, 16, and 17 of the two bag portions 12 and 13. Yes. A large number of particulate water-absorbing polymers 25 are distributed and stored in the two bags 12 and 13 at equal densities. For example, the cooling scarf 10 preferably has a total length of 70 to 110 cm, a width of 3 to 7 cm, and a length of the main body 11 of about 30 to 60 cm. The standard size of the cooling scarf 10 is about 104 cm in length and about 5.5 cm in width, and the cooling scarf 10 for adults is about 92 cm in length and about 5.5 cm in width. The cooling scarf 10 for use has a total length of about 82 cm and a width of 5.5 cm.

  Although the water-permeable sheet allows water to pass therethrough, the particles of the water-absorbing polymer 25 have a stitch size that does not allow water to pass. For example, 100% cotton cloth can be used as the water permeable sheet. Therefore, the main body 11 can easily pass water, and thus the bag portions 12 and 13 can also easily pass water. When the bag portions 12 and 13 are put on water, the water penetrates into the bag portions 12 and 13. Specific examples of the cloth used as the water-permeable sheet are woven cloth, and the density of the crushed fiber is preferably 200 / inch or more, preferably 200 to 280 / inch, or polyester mainly composed of cotton, It is a blend with acrylic, nylon, etc. The proportion of cotton in the case of blending is preferably 60% by mass or more. A cloth having an air permeability of 8 cm 3 / cm 2 · sec or less is used.

  As described in detail later, the band-shaped main body 11 is formed by folding a water-permeable sheet into four so as to form folds parallel to the longitudinal direction so as to form two bag portions 12 and 13. The overlapping end portions of the four sheets formed by bending are sewn while winding the sheets with a winding lock. FIG. 2 is a diagram showing how the main body 11 is sewn. In FIG. 2, in order to form the main body 11, the water-permeable sheet 1 is folded into four so that a crease is formed in parallel to the longitudinal direction, and the folded end portions 22 of the four sheets are formed. Is formed. The end portions 22 are further bent every four sheets. In a state where the end 22 is bent, a winding lock is applied using a wooly yarn 23. Thereby, the winding lock part 24 shown in FIG. 1 is formed. Thereby, the intensity | strength of joining of sheets increases and the possibility that the water absorption polymer 25 which is the content covered with the cotton sheet will leak from the sheet surface from the perforation in the conventional method can be reduced. In addition, since the sheet is locked so as to be folded while being folded in two, it leads to reinforcement.

  The water-absorbing polymer 25 housed in the bag portions 12 and 13 quickly gels the polymer itself and retains water by a high water-absorbing action, which is said to be about 400 times when attached to water. The water-absorbing polymer 25 is made of a granular water-absorbing resin. For example, a water-absorbing polymer 25 having a particle size of 800 to 2000 μm or a particle size of 200 to 800 μm is used. When a water-absorbing polymer having a particle size of 800 to 2000 μm is used, there is shape stability, but it takes more time for the water-absorbing polymer to expand due to water absorption than a polymer having a small particle size. On the other hand, when a water-absorbing polymer having a particle size of 200 to 800 μm is used, the time until expansion due to water absorption is less than that of a large particle size, but the water becomes soft after water absorption. It is lower than when a large particle size is used. Therefore, in order to shorten the time until the water-absorbing polymer expands due to water absorption, and to provide shape stability and tension, a water-absorbing polymer having a particle size of 800-2000 μm and a water-absorbing polymer having a particle size of 200-800 μm are mixed. And preferably used. Since the fabric has an air permeability of 8 cm 3 / cm 2 · sec or less, the water absorbing polymer 25 does not spill outside before water absorption. Since the bag parts 12 and 13 are divided by the winding lock part 24 and the end parts 18 and 19 are sewn by the winding lock as will be described later, the water absorbing polymer 25 moves the bag parts 12 and 13 before water absorption. The water-absorbing polymer is evenly distributed between the two bag portions.

  The water-absorbing polymer 25 includes, for example, starch or cellulose, a water-soluble monomer containing a hydrophilic group such as a carboxyl group or a sulfonic acid group and / or a monomer that becomes water-soluble by hydrolysis, and a crosslinking agent as essential components. And a water-absorbing resin obtained by polymerizing, if necessary, by hydrolysis. Since the water-absorbing polymer 25 is in a gel state when it absorbs water and does not convect water, once it is cooled in a refrigerator or the like, the water-absorbing polymer 25 has a function of keeping the cooling state for a long time. By storing the absorbent polymer 25 in two bag parts, the absorbent polymer 25 is distributed so that there is no deviation in the bag part and the density thereof is uniform, and the cold-retaining effect during use is also maintained uniformly. FIG. 3 is a cross-sectional view of the main body 11 of the sheet 11 formed after the cooling scarf 10 shown in FIG. The water-absorbing polymer 25 accommodated in the bag portions 12 and 13 of the main body 11 expands due to water absorption, and the bag portions 12 and 13 also expand. By absorbing heat when the water absorbed in the water-absorbing polymer 25 evaporates, the body heat is taken away, the body temperature is stabilized, and a pleasant cool feeling can be maintained for a long time.

  In FIG. 1, strip-shaped end portions 18 and 19 are sewn to both ends of the strip-shaped main body 11 so as to close the openings 14, 15, 16 and 17 of the two bag portions 12 and 13. The band-shaped end portions 18 and 19 are sewn while winding the sheet with a winding lock on the overlapped end portion of the belt-shaped main body 11 by overlapping another sheet folded into four sheets. Yes. The end portions 18 and 19 play a role of being tied together to fix the cooling scarf 10 to the neck. FIG. 4 is a view showing a state of sewing the belt-like main body 11 and the belt-like end portions 18 and 19. The end portion 18 is turned over and the both end portions are sewn to the main body 11. After sewing, return to the front side.

  FIG. 5 is a diagram illustrating a usage state of the cooling scarf 10 and illustrates a state in which the cooling scarf 10 is wound around the neck. The cooling scarf 10 wound around the neck K with an appropriate strength has its bag portions 12 and 13 stably in contact with the neck and exerts a cooling action on the neck by conduction, and both end portions 18 and 19 thereof are By tying them together in front, the cooling scarf 10 is stably held in its neck while being held on its neck. The water-absorbing polymer 25 in the bag portions 12 and 13 has a so-called long-time cold-retaining function of maintaining the cooling state for a long time once cooled in a refrigerator or the like because the water is gelled as described above. Therefore, it is convenient to use it when playing sports in summer.

  Next, with reference to FIGS. 6-8, the manufacturing method of the scarf for cooling which concerns on embodiment of this invention is demonstrated.

Have. A large number of particulate water-absorbing polymers 25 are distributed and stored in the two bags 102 and 103 at equal densities. In the fourth embodiment, each material constituting the cooling scarf 100 is the same as that in the first embodiment, and the first way of sewing the band-shaped end portions 108 and 109 to both ends of the band-shaped main body is as follows. Unlike the sewing with the winding lock in the embodiment, the only difference is that sewing is performed by two main stitches. Therefore, hereinafter, only a method of sewing the band-shaped end portions 108 and 109 to the band-shaped main body 101 will be described.

  As shown in FIG. 15, the band-shaped main body 101 is produced by performing the first sewing process shown in FIGS. 7A to 7F described in the first embodiment (FIG. 15A). ). Next, as shown in FIG.15 (b), the part 110 which consists of a water-permeable sheet is prepared, and the part 110 is folded in half as shown in FIG.15 (c). As shown in FIG. 15 (d), the part 110 is folded in half, and the part that is folded and combined is finally sewn as indicated by reference numeral 111, and the left end indicated by reference numeral 112 is folded back for finishing sewing. Thereby, the cylindrical sheet 110a shown in FIG.15 (e) is obtained. Next, the belt-like main body 101 shown in FIG. 15A is put into the cylindrical sheet 110a shown in FIG. And as shown in FIG.15 (f), the edge part 101a of a strip | belt-shaped main body and the edge part 110b of the cylindrical sheet | seat 110a are match | combined, and two places shown by the code | symbols 101b and 101c are sewn by a main stitch. Thereafter, as shown in FIG. 15G, the cylindrical sheet 110a is returned to the front side, and the portion indicated by reference numeral 110c is stitched. Thereby, the band-shaped end portion 108 shown in FIG. 14 is completed. Then, the water-absorbing polymer 25 is inserted from the opening at the other end of the belt-like main body 101 so that the amount of the two bag portions is the same amount, and in the same manner as the belt-like end portion 108 shown in FIG. Thus, the belt-shaped end portion 109 is sewn to the belt-shaped main body 101. In this way, a cooling scarf can be manufactured.

  In the fourth embodiment, a seam is used to lock the sewing portion when forming the bag portion of the belt-like main body 101, and when sewing the belt-like end portions 108 and 109 to the belt-like main body 101, two main stitches are used. A place was provided. In the longitudinal direction of the belt-like main body 101, when the sewing portion for forming the two bag portions is a main stitch or the like as in the prior art, the seam shown in FIG. When hand-rubbed or the like, as shown in FIG. 16 (b), the non-uniformity may increase, and a portion larger than the particle size of the water-absorbing polymer occurs, and the water-absorbing polymer moves between the bags from the portion. It will happen. However, the width direction of the belt-like body, that is, the sewn portion with the belt-like end portions 108 and 109 has a short length in the width direction. Therefore, the non-uniformity of the seam shown in FIG. It does n’t happen much when you do. Further, since the hand fir is a band-shaped scarf, it is mainly performed in the width direction, and the force acting on the water-absorbing polymer by the hand acts in the width direction, so that the water-absorbing polymer moves easily between the bags. However, the force to move the water-absorbing polymer to the belt-like end hardly occurs when the hand is held. Accordingly, the sewing portion between the belt-like main body 101 and the belt-like end portions 108 and 109 is sufficiently effective even by the main sewing as in the present embodiment. In this case also, the water-absorbing polymer leaks out from the bag. And movement can be prevented.

  When the band-shaped end portions 108 and 109 are sewn to the band-shaped main body 101 by sewing, after the surface of the band-shaped main body 101 and the back surface of the band-shaped end portions 108 and 109 are sewn from the back side of the fabric. Inverted, band-shaped end portions 108 and 109 are formed. For this reason, there are no holes in the sewing machine for the lock stitch on the surface of the band-shaped main body 101 after the band-shaped end portions 108 and 109 are formed. Therefore, it is possible to prevent the water-absorbing polymer from leaking out from the hole of the sewing machine.

  Further, in the case of the main stitching of the band-shaped end portions 108 and 109 with the band-shaped main body 101, the bonding strength between the band-shaped end portions 108 and 109 and the band-shaped main body 101 is obtained by performing two main stitches with a gap therebetween. In addition, the bonding strength of the openings 104, 105, 106, and 107 of the two bag portions 102 and 103 of the belt-like main body 101 can be increased, and can be tightly closed. Thereby, it is possible to prevent the water-absorbing polymer from moving from the band-shaped main body 101 to the band-shaped end portions 108 and 109.

  Accordingly, the sewing portion between the belt-like main body 101 and the belt-like end portions 108 and 109 is sufficiently effective even by the main sewing as in the present embodiment. In this case also, the water-absorbing polymer leaks out from the bag. And movement can be prevented.

  In addition, although the sewing of the belt-like main body and the belt-like end portion described in the second embodiment and the third embodiment has been described by sewing with a winding lock, the second embodiment and the third embodiment The cooling scarf can also be produced by sewing the main body and the belt-like end portion by the main sewing described in the fourth embodiment.

  The configurations, arrangement relationships, and the like described in the above embodiments are merely schematic to the extent that the present invention can be understood and implemented. Therefore, the present invention is not limited to the described embodiments, and can be variously modified without departing from the scope of the technical idea shown in the claims.
