Description

  The present invention relates to a cooling device disposed inside a collar of a garment.

  Conventionally, various cooling devices that are wound around the neck have been proposed. For example, in Patent Document 1, the entire circumferences of a pair of fabric bodies formed in a belt shape are stitched together, and a large number of granular superabsorbent resins are accommodated in a closed space formed inside. If water is contained in the cooling device before use, water is retained in the superabsorbent resin. If the cooling device is wrapped around the neck in this state, the circumference of the neck can be cooled. Can be obtained. Further, this cooling device accommodates a C-shaped elastic body in order to impart shape retention.

Utility Model Registration No. 3167405

  However, in the cooling device, since the elastic body is provided separately, there are problems that the number of parts is large and the thickness is bulky. The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a cooling device that has a small number of parts and is not bulky while maintaining fit around the neck.

  The present invention is a cooling device disposed on the inner side of a collar of clothes, and a plurality of inner bags containing a cooling agent and a connecting portion for connecting the adjacent inner bags are integrally formed. An inner bag connecting body, wherein the inner bag connecting body is formed in a flat shape by a pillow package sealed by a center seal extending along a connecting direction of the plurality of inner bags, and the cooling agent is supplied to each Housed in an inner bag.

  Since this cooling device has an inner bag connecting body in which a plurality of inner bags are connected via a connecting portion, the connecting portion bends so that the shape around the neck can be appropriately fitted. Moreover, since the inner bag coupling body is formed by pillow packaging sealed with a center seal, the center seal is disposed on any surface of the inner bag coupling body formed in a flat shape. For this reason, the width of the cooling device can be made narrower than that of a so-called side seal, and it can also be accommodated inside the narrow collar of clothes. In addition, by providing the center seal, the shape retention can be provided against the bending of the connecting portion of the inner bag connector, so that the fitting property can be improved. As described above, in the present invention, by providing the center seal, for example, the shape of the cooling device is maintained without using a separate member such as a C-shaped elastic body as described in Patent Document 1. Therefore, it is possible to prevent the thickness from being bulky. Therefore, it is suitable to be placed inside the garment collar.

  In the cooling device, the number of inner bags is preferably an odd number, particularly preferably 3, 5, or 7, and particularly preferably 5. In this way, when the number of inner bags is odd, the inner bag is placed at the center of the back of the neck where the most effective force is applied when the cooling device is placed inside the collar. It can be received by the bag, and the cooling device can be prevented from slipping in the collar. In addition, by setting the number of inner bags to 5, the size of the inner bag can be made appropriate to the length around the neck of the collar.

  Moreover, in the said cooling device, the notch extended in the said width direction can be formed in each connection part of an inner bag coupling body from the edge part of the width direction orthogonal to a connection direction. If it does in this way, an inner bag coupling body can be formed in circular arc shape by extending notch | incision. Therefore, the fitting property around the neck can be further improved. In addition, it is necessary to form the notch into a length that does not divide the center seal so as not to interfere with the effect of the center seal described above.

  In the said cooling device, while curving in circular arc shape and being formed in strip | belt shape, the outer bag which accommodates an inner bag coupling body can further be provided. With such an outer bag, for example, it is possible to prevent dew condensation from the cooling agent from adhering directly to the collar. In addition, for example, when the outer bag is formed of a material having a high frictional force, it can be prevented from falling when the cooling device is attached to the inside of the collar. In addition, when a cut is formed in the inner bag coupling body so that the inner bag coupling body can be deformed into an arc shape, the inner bag coupling body can be maintained in an arc shape by being accommodated in the outer bag.

  When such an outer bag is used, a length that does not divide the center seal is formed in each connecting portion of the inner bag connecting body by forming a notch extending in the width direction from an end in the width direction orthogonal to the connecting direction. Further, the inner bag connector can be accommodated in the outer bag so that the end portion where the cut is formed faces the convex side of the arc. And an engaging part engaged with each notch of an inner bag coupling body can be provided in an outer bag. Thus, since the engaging part of an outer bag engages with the notch | incision of an inner bag coupling body, the movement to the longitudinal direction of an inner bag coupling body within an outer bag can be prevented. As a result, the cooling device can be prevented from being deformed.

  The above-mentioned cryogen can be variously configured, for example, can be made into a freezeable hydrogel. Thereby, since an inner bag coupling body can be hardened, shape collapse can be prevented further. In addition, a cryogen that does not solidify even when frozen and has fluidity can be used.

  According to the cooling device according to the present invention, the number of parts can be reduced while maintaining the fit around the neck, and further, it can be prevented from becoming bulky.

(First embodiment)
Hereinafter, a first embodiment of a cooling device according to the present invention will be described with reference to the drawings. FIG. 1 is a plan view of the cooling device, and FIG. 2 is a cross-sectional view taken along line AA and BB of FIG. In the following, for convenience of explanation, the vertical direction in FIG. 1 is referred to as the width direction, and the left-right direction is referred to as the longitudinal direction.

  As shown in FIG. 1, the cooling device according to the present embodiment is disposed on the inner side of a collar and has an inner bag connector 1 formed in a belt shape. The inner bag connector 1 is formed by connecting a plurality of inner bags 11 in the longitudinal direction, and in this example, five inner bags 11 are connected. Each inner bag 11 is formed in a rectangular shape, and contains a cryogen 12 containing a hydrous gel that can be frozen. Although the well-known thing containing water, a thickener, a pH adjuster etc. can be used for the cryogen 12, in order to improve the freezing performance mentioned later, it is preferable that there is as much content of water as possible (for example, 80 % By weight). Adjacent inner bags 12 are connected to each other by a connecting portion 13 extending in the width direction in a band shape. This inner bag coupling body 1 accommodates a cooling agent by a known pillow packaging.

  In pillow packaging, after forming a center seal 10 that seals the ends of plastic films such as polyethylene, PET, polypropylene, nylon, ethylene vinyl acetate, cellophane, polyvinyl chloride, and polyvinylidene chloride, An end seal 15 is formed by sealing one end of the direction. At this time, the center seal 10 is arranged between both ends of the end seal 15 in the width direction (see FIG. 2). Then, after injecting a predetermined amount of cold-retaining agent from the opening at the other end in the axial direction of the film formed in a cylindrical shape, a predetermined interval is provided in the axial direction from the end seal 15 in the same direction as the end seal 15. Then, the plastic film is sealed to form the connecting portion 13. Then, injection | pouring of a cold insulating agent and formation of a connection part are repeated, and after inject | pouring a cold insulating agent 5 times and forming the edge part seal | sticker 15, the inner bag coupling body 1 shown in FIG. 1 will be completed. As described above, the inner bag coupling body 1 is formed in a cylindrical shape by sealing the plastic film with the center seal 10, but by providing the end seal 15 and the coupling portion 13 described above, FIG. 1 and FIG. 2 is formed in a flat shape as shown in FIG. 2, and the center seal 10 is formed on one surface thereof. That is, the center seal 10 is disposed so as not to protrude from the end portion of the inner bag 11 in the width direction. In addition, although not illustrated, each inner bag 11 can be made into a shape in which the corners of the four corners are cut off by changing the shape of the connecting portion 13 and the end seal 15, and thus frozen. It can prevent that the corner | angular part of the cold insulating agent 12 pierces the inner bag 11 with an impact etc., and is torn.

  The cooling device formed as described above is first accommodated in a freezer or the like, and after the cryogen is frozen, it is placed inside the collar as shown in FIG. Thereby, the neck circumference is cooled and a refreshing feeling can be obtained.

  The cooling device configured as described above can obtain the following effects. That is, since the plurality of inner bags 11 are constituted by the inner bag connector 1 connected through the connecting portion 13, the plurality of inner bags 11 form a desired angle when the connecting portion 13 is bent. Therefore, it is possible to appropriately fit the shape of the neck. Moreover, since the inner bag coupling body 1 is formed by pillow packaging, the center seal 10 that seals the inner bag coupling body 1 is disposed on any surface of the inner bag coupling body 1 formed in a flat shape. . Therefore, the width can be narrowed and can be accommodated inside the collar of a narrow garment. In addition, although divided into a plurality of inner bags 11, by providing the center seal 10, it is possible to provide shape retention so as to resist the bending of the connecting portion 13, and thus the fitting property can be improved. . As described above, by providing the center seal 10, shape retention can be imparted to the cooling device without using a separate member, so that the thickness can be prevented from becoming bulky. Therefore, it is suitable to be placed inside the garment collar.

  Further, by setting the number of the inner bags 11 to an odd number such as “5”, the inner bag 11 in the middle of the inner bag connector 1 can be arranged in the center at the back on the neck. Thereby, the generated force can be received by the inner bag 11 at the center of the back of the neck where the force is most likely to be generated. As a result, the cooling device can be prevented from shifting downward in the collar.

  By the way, the said cooling device can be comprised as shown in FIG.4 and FIG.5 in order to make it fit the curved surface around a neck. FIG. 4 is a plan view of this example, and FIG. 5 is a partially enlarged rear view of FIG. As shown in FIG. 4, in this example, a cut portion 14 extending in the width direction from one end in the width direction is formed in the connection portion 13 of the inner bag connection body 1. It is preferable that the length of the notch 14 is set to be not less than half the length of the connecting portion 13 in the width direction. However, as shown in FIG. 5, the cut 14 needs to have a length that does not cut the center seal 10 over the entire width direction. With the above configuration, when the cut 14 of each connecting portion 13 is widened, the inner bag connector 1 is formed in an arc shape as a whole. Therefore, it can be appropriately fitted around the neck. In particular, when it is arranged inside the collar with the convex side of the arc facing upward, it is possible to further prevent protrusion downward.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to the drawings. 6 is a plan view of the cooling device according to this embodiment, FIG. 7 is a plan view of the outer bag of the cooling device of FIG. 1, and FIG. 8 is a cross-sectional view taken along the line CC of FIG.

  As shown in FIG. 6, the cooling device according to the present embodiment is arranged on the inner side of the collar, and has an outer bag 2 formed in a belt shape and an inner bag connection accommodated in the outer bag 2. And a body 1. The inner bag connector 1 is the same as that shown in FIGS. 4 and 5. As shown in FIG. 7, the outer bag 2 preferably has a longitudinal length L of 100 to 400 mm and a width D of 10 to 45 mm. Moreover, in order to make it fit appropriately when wound around the neck, the outer bag 2 is formed in circular arc shape. As an example of such an arc shape, the curvature radius of the edge portion on the convex side of the arc in the outer bag 2 is preferably 30 cm or more. In the following, for convenience of explanation, with reference to FIG. 7, the upper side is referred to as the convex side (of the arc) and the lower side is referred to as the concave side.

  The outer bag 2 is formed by sewing two pieces of fabric. More specifically, two pieces of fabric are overlapped, and a pair of long sides 21a, 21b extending in the longitudinal direction and a peripheral edge of one short side 22a are sewn with the thread 24, and then turned over. Is formed. Thereby, as shown in FIG. 8, since the seam allowance 25 is accommodated in the outer bag 2, the width of the outer bag 2 can be reduced. Moreover, as shown in FIG. 7, the inner bag coupling body 1 mentioned above is accommodated from the opening formed in the other short side 22b which is not sewn together. The fabric constituting the outer bag 2 can be formed of various materials, for example, polyethylene, PET, polypropylene, nylon, acrylic, polyurethane, acetate, cotton, hemp, silk, rayon, cupra, etc. Can do. In particular, polyethylene, PET, polypropylene, nylon, acrylic, polyurethane, and acetate are preferable from the viewpoint of quick-drying, and the outer bag 2 becomes wet due to condensation from the inner bag connector 1 or user's sweat as described later. Can be prevented. These materials may be used alone or in combination. Moreover, in order to transmit the cooling effect from the inner bag coupling body 1 as described later, the thickness of the fabric of the outer bag 2 is preferably 0.5 mm or less. Further, as the color of the fabric of the outer bag 2, it is possible to adopt a white color that does not stand out when it protrudes, a light blue color that indicates coolness, etc. in consideration of being arranged inside the collar.

  As described above, since the notch 14 is formed in the connecting portion 13 of the inner bag connector 1, it can be formed into an arc shape by widening it. Therefore, the inner bag connector 1 is accommodated from the opening of the outer bag 2 so that the cut 14 faces the convex side. However, as shown in FIGS. An engaging portion 23 is provided in a portion corresponding to. The engaging portion 23 extends along the width direction from the convex end of the outer bag 2 and is formed by sewing the opposing surfaces of the outer bag 2 with a thread (see FIG. 9A). ).

  The engaging portion 23 as described above is formed before the inner bag connector 1 is accommodated in the outer bag 2. Hereinafter, a method for accommodating the inner bag connector 1 in the outer bag 2 will be described with reference to FIG. 9. FIG. 9A is a cross-sectional view taken along the line DD of FIG. 7, and is a cross-sectional view of the outer bag 2 at a position where the engaging portion 23 is formed. First, from the state shown in FIG. 9 (a), as shown in FIG. 9 (b), the outer bag 2 is flattened so that positions other than where the engaging portions 23 are formed are arranged at both ends in the cross section. Form into shape. In this state, the inner bag connector 1 is inserted from the opening 22b of the outer bag 2 as shown in FIG. When the insertion is completed, the outer bag 2 is rotated around the inner bag connector 1 around the longitudinal direction of the outer bag 2 as shown in FIG. Then, the engaging portion 23 is positioned at the position where the engagement portion 23 is disposed in the cut 14 of the inner bag connector 1. In this state, as shown in FIG. 9 (d), the outer bag 2 is formed in a flat shape, but has a flat shape in which the peripheral edges 21a and 21b and the engaging portions 23 of each fabric are located at both ends in the cross section. In plan view, the arc shape is as shown in FIG. In this state, when the opening 22b of the outer bag 2 is sewn and closed, the cooling device according to the present embodiment is completed. At this time, as shown in FIG. 6, the inner bag connector 1 is formed in an arc shape as a whole by expanding the cuts 14 of the respective connecting portions 13 so as to conform to the arc shape of the outer bag 2. Fits the shape of bag 2.

  The cooling device formed as described above is housed in a freezer or the like as in the first embodiment, and after the cryogen is frozen, it is housed under the collar. At this time, the cooling device is arranged inside the collar so that the convex side faces upward. Thereby, since the cooling device is arranged inside the collar while being curved upward, it is possible to prevent the cooling device from protruding downward from the lower edge of the collar on the back side of the neck where the deviation is most likely to occur.

  As described above, since the cooling device according to the present embodiment includes the outer bag 2, it is possible to prevent, for example, condensation from the cold insulating agent from directly attaching to the collar. Further, when the outer bag 2 is formed of a material having a large frictional force, when the cooling device is mounted on the inside of the collar, the outer bag 2 and the collar can be prevented from falling due to the frictional force. Furthermore, by accommodating the inner bag coupling body 1 in the outer bag 2, the inner bag coupling body 1 can be maintained in an arc shape. Moreover, in the said cooling device, since the engaging part 23 engaged with each notch 14 of the connection part 13 of the inner bag coupling body 1 is provided in the outer bag 2, the inner bag connection in the outer bag 2 is provided. The movement of the body 1 in the longitudinal direction can be reliably prevented. In addition, the outer bag 2 has a seam allowance 25 between the fabrics, so it is easy to swell in a cylindrical shape, but since the engaging portion 23 is formed by sewing the opposing surfaces of the fabric as described above, The outer bag 2 can be maintained in a flat shape. Thereby, the inner bag coupling body 1 can be prevented from rotating around the axis about the longitudinal direction in the outer bag 2. Therefore, it is possible to reliably prevent the inner bag connector 1 from moving or rotating in the outer bag 2.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to this, A various change is possible unless it deviates from the meaning. For example, when the notch 14 is formed in the inner bag connecting body 1, the inner bag connecting body 1 can be formed in an arc shape, but when a force acts on the outer bag 2, the notch 14 is torn and the inner bag 11 side There is a possibility to extend. If it will be in such a state, there exists a possibility that the refrigerant | coolant 12 may flow out from the inner bag 11. FIG. For example, it can be configured as shown in FIG. In the example of FIG. 10A, a pair of thin restricting portions 16 are formed in the connecting portion 13 so as to sandwich the notch 14 and extend in the width direction at the boundary with the inner bag 11. If such a restricting portion 16 is formed, even if the torn cut 14 reaches the restricting portion 16, the notch 14 extends along the thin restricting portion 16. That is, since the restricting portion 16 extends along the boundary with the inner bag 11, it does not reach the inner bag 11 even if the cut 14 extends. Therefore, it is possible to prevent the cut 14 from extending beyond the connecting portion 13 to the adjacent inner bag 11, and as a result, it is possible to prevent the coolant 12 from leaking from the inner bag 11. In addition, this control part 16 can also be formed with a perforation. Further, the same effect can be obtained even if the restricting portion 16 is formed thick. Furthermore, for example, as shown in FIG. 10B, a thin guide portion 17 extending from the tip of the cut 14 to the concave side can be provided. Providing such a guide portion 17 prevents the cut 14 from reaching the inner bag 11 because it is torn along the guide portion 17 even if a force acts so that the cut 14 is torn. can do. Further, the guide portion 17 can be formed by a perforation in addition to a thin wall. Further, as shown in FIG. 10C, the tip 18 of the cut 14 is curved so as to face the convex side, or as shown in FIG. It can also be formed. Even in this case, the cut 14 can be prevented from reaching the inner bag 11.

  In the said embodiment, although the engaging part 23 is formed by sewing the surface which the outer bag 2 opposes with a thread | yarn, if the surfaces where the outer bag 2 opposes are being fixed, especially except a thread | yarn It is not limited, In order to prevent the movement of the inner bag connector 1 in the longitudinal direction, the engaging portion 23 may only be engaged with the notch. In addition, the engaging portion 23 can be formed after the inner bag connector 1 is stored in the outer bag 2.
