Japanese Unexamined Patent Publication No. 2006-95200

The cooling sheet is attached to the human body due to the adhesiveness of the gel layer. In addition, the cooling sheet takes heat away from the latent heat of vaporization of the water contained in the gel layer and cools it. Therefore, when the cooling sheet is used for a long time, the gel layer shrinks due to a decrease in water content, and the adhesive area decreases.

In addition, there is a desire to attach a cooling sheet to the area below the eyes of the face for use. However, since the area is narrower than the forehead, the area of the cooling sheet attached to the area needs to be smaller than that of the cooling sheet attached to the forehead. Such a cooling sheet having a small area is used for a long time, and when the gel layer shrinks due to a decrease in the amount of water and the adhesive area decreases, the adhesive force required for attachment to the human body cannot be obtained. There is a risk. Therefore, there is a problem that the cooling sheet used by being attached to the area below the eyes of the face is not suitable for long-term use.

Hereinafter, the cooling sheet according to the embodiment of the present invention will be described with reference to the drawings. The configurations of the following embodiments are examples, and the present invention is not limited to the configurations of these embodiments.

FIG. 1 is a plan view of the cooling sheet according to the embodiment. FIG. 2 is a cross-sectional view taken along the line AA shown in FIG. The cooling sheet 1 has a horizontally long oval shape as a whole. The cooling sheet 1 includes a sheet-shaped base layer 2 and a gel layer 3 arranged on one surface of the base layer 2. The cooling sheet 1 has a layer structure in which a gel layer 3 is laminated on a base layer 2.

The base layer 2 is a mount that supports the gel layer 3. A woven fabric, a non-woven fabric, a film, or the like can be used for the base layer 2. Specifically, for the base layer 2, a woven fabric of synthetic fibers such as cellulosic fibers and acrylic, a non-woven fabric, polypropylene, polyethylene, a film such as polyethylene terephthalate is used.

The gel layer 3 is formed by gelling (gelling) water (purified water) with a gelling agent. As the gelling agent, polysaccharides such as carrageenan, locust bean gum, xanthan gum and guar gum, and known ones such as gelatin, agar and pectin can be used. In addition, the gel layer 3 has adhesiveness that can be adhered to the skin of the human body. Therefore, in the gel layer 3, the amount of the gelling agent is adjusted so as to maintain the adhesiveness and shape retention. The gel layer 3 may contain preservatives, preservatives, stabilizers, fragrances, colorants, pH adjusters and the like.

The gel layer 3 is adhered to the skin of the human body. The gel layer 3 absorbs heat from the human body as the contained water evaporates, thereby cooling the gel layer 3. In this way, the cooling sheet 1 cools the human body by utilizing the latent heat of vaporization of the gel layer 3. In the unused cooling sheet 1, a release sheet such as a film is attached to the surface of the gel layer 3, and the release sheet 1 is used after the release sheet is peeled off.

FIG. 3 is a diagram showing a usage example of the cooling sheet 1 according to the present embodiment. The cooling sheet 1 according to the present embodiment is used for cooling the region A (“predetermined region” in the present application) under the eyes of the face F. As shown in FIG. 3, in the cooling sheet 1, the gel layer 3 is adhered to the region A in the used state. In this usage state, the longitudinal direction of the cooling sheet 1 faces the left-right direction of the face F. In the cooling sheet 1, the gel layer 3 is adhered to the region A according to the instruction display means for instructing the attachment position. This instruction display means may be enclosed in the cooling sheet 1, or may be printed on a release sheet, a package, or the like. The instruction display means may include an illustration as shown in FIG.

The cooling sheet 1 is attached to the region A by exerting the adhesive force of the gel layer 3 on the skin. Further, the cooling sheet 1 needs to contain water for realizing cooling for a long time (for example, about 10 hours) in the gel layer 3. The cooling sheet 1 attaches the gel layer 3 containing an amount of water required for long-term cooling to the skin, but there is a risk that the adhesive force of the gel layer 3 alone will not provide the force required for attachment to the skin. be. Further, when the cooling sheet 1 is used for a long time, the water contained in the gel layer 3 is reduced by evaporation, and the gel layer 3 shrinks. As a result, when the cooling sheet 1 is used for a long period of time, it is in a state of being adhered only near the edge of the gel layer 3 to the skin, the adhesive area with the skin is reduced, and the cooling sheet 1 is easily peeled off.

Here, the cooling sheet 1 according to the present embodiment includes a mask contact portion 4 that abuts on the upper edge portion of the mask in a state where the gel layer 3 is adhered to the region A of the face F when the mask is attached.

FIG. 4 is a diagram showing an example of using the cooling sheet 1 when the mask is attached. As shown in FIG. 4, the mask 101 is attached from above the cooling sheet 1 in a state of being attached to the region A. Here, the mask 101 will be described. FIG. 5 is an external perspective view of the mask 101. As shown in FIG. 5, the mask 101 has a mask body 102, ear straps 103, 104, side portions 105, 106, nose fitter 107, and upper edge portion 108. The mask body 102 is made of a sheet-like breathable material and has a size capable of covering the wearer's mouth and nose. The ear straps 103 and 104 are made of a string-shaped elastic material, and the ends are joined to the side portions 105 and 106 located on both sides of the mask body 102 so that the ear straps 103 and 104 are joined to the left and right sides of the mask body 102. Each ring is formed. The mask 101 is a hygienic mask used for infectious disease control and the like.

The mask main body 102 is composed of various sheets such as a breathable non-woven fabric, and is a laminated body of a plurality of sheets. The plurality of sheets are appropriately joined to each other at the upper, lower, left, and right edges and the like. The mask body 102 has creases that can form a pleated three-dimensional shape. In such a crease, the side portions 105 and 106 are joined to the left and right end portions in a state where the mask main body 102 is folded in a fold shape, and the shape thereof is held by the side portions 105 and 106. That is, the creases are prevented from unfolding at the side portions 105 and 106 of the left and right end portions, and the creases are unfolded when the mask 101 is attached in the region near the center of the mask body 102, whereby the pleats of the mask body 102 are pleated. Is expanded to form a three-dimensional shape. By closing the pleats when not attached, the mask body 102 can be made into a flat surface without being bulky.

The string-shaped elastic material constituting the ear strings 103 and 104 may be, for example, a mixed woven band of rubber thread and cotton, or
It is made of a mixed knitted net of resin filaments, elastic non-woven fabric, and the like. By joining both ends of such a string-shaped material to the side portions 105 and 106 of the left and right sides of the mask body 102, one end of the material becomes the starting point and the other end of the material ends. The loop-shaped ear straps 103 and 104 are formed on both the left and right sides of the mask body 102.

The nose fitter 107 is a member fixed to the mask main body 102 in a state where the longitudinal direction extends in the left-right direction of the mask main body 102 at the upper edge portion 108 of the mask main body 102. The nose fitter 107 may be fixed to the inside of the laminated body in a state of being sandwiched between the sheet-like breathable materials constituting the mask main body 102, or may be fixed to the surface of the mask main body 102. May be good. The nose fitter 107 is a plastically deformable material having strength enough to be deformed into an appropriate shape by being pressed by the wearer with a finger and maintaining the shape even when released from the pressing. By providing such a nose fitter 107 on the upper edge portion 108 of the mask body 102, the wearer can close the gap formed between the nose and the mask body 102.

The above-mentioned materials constituting the mask 101 are preferably bonded by ultrasonic welding, but for example, stitching with a sewing thread or the like, bonding with a hot melt adhesive or the like, heat sealing, and various other bonding techniques can be applied. ..

The mask contact portion 4 of the cooling sheet 1 is a portion substantially parallel to the upper edge portion 108 when the mask 101 is attached. The upper edge 108 of the mask 101 is pressed against the wearer's face F side by the ear straps 103 and 104. The cooling sheet 1 is provided with the mask contact portion 4 that comes into contact with the upper edge portion 108 of the mask 101, so that the cooling sheet 1 is pressed against the wearer's face F side by the upper edge portion 108. As a result, the cooling sheet 1 can be maintained without peeling from the region A even when the gel layer 3 shrinks and the adhesive strength decreases. As described above, the cooling sheet 1 according to the present embodiment can be used by being attached to the region A below the eyes of the face F.

Further, a nose fitter 107 is arranged on the upper edge 108 of the mask 101. For the nose fitter 107, a shape memory member having a thickness of about 5 mm and made of polypropylene or the like is used. The nose fitter 107 is attached to the inside of the sheet in which the upper edge portion of the sheet constituting the mask body 102 is folded back. In the mask 101, for example, an ultrasonic welding portion may be provided around the nose fitter 107 in order to prevent the nose fitter 107 from being displaced. The width of the formed region of the ultrasonic welded portion is about 5 mm.

The cooling sheet 1 has a width direction in a direction along the vertical direction of the face F in a state of being adhered to the region A. Since the upper edge 108 of the mask 101 comes into contact with the face F, when the cooling sheet 1 is attached to the region A of the face F together with the upper edge 108, the length W of the cooling sheet 1 in the width direction (FIG. 1). (See) is preferably 10 mm or more. As a result, the mask contact portion 4 can be arranged at a position corresponding to the nose fitter 107 of the mask 101, and the cooling sheet 1 can be suppressed to the face F side by the nose fitter 107. As described above, by using the mask 101 provided with the nose fitter 107 in combination with the cooling sheet 1, the cooling sheet 1 can be more reliably pressed against the wearer side, so that the cooling sheet 1 can be prevented from peeling off.

Further, if the length W in the width direction of the cooling sheet 1 exceeds 30 mm, it interferes with the ala of nose of the face F, and the cooling sheet 1 floats up at the ala of nose. This causes the cooling sheet 1 to peel off. Therefore, the length W in the width direction is preferably 30 mm or less.

Next, the cooling sheet 1 according to the present embodiment will be further described with reference to FIGS. 1 and 3. The cooling sheet 1 includes cheek adhesive portions 5L and 5R that are adhered to the cheeks in a state of being adhered to the region A of the face F. The cheek adhesive portion 5L is adhered to the cheek on the left side of the face F. Cheek adhesive part 5R is face F

Generally, the cheek is a flat portion on the face below the eyes, and the cooling sheet 1 is provided with cheek adhesive portions 5L and 5R that adhere to the cheeks to provide an adhesive area with the skin in the region R. It can be secured and peeling can be prevented.

Further, when the cooling sheet 1 is also adhered to the nose, the cooling sheet 1 is easily peeled off in the nose because the nose generally has many irregularities and few flat portions. Therefore, the cooling sheet 1 according to the present embodiment is provided with the cheek adhesive portions 5L and 5R, so that the cooling sheet 1 can be maintained in a state of being attached to the nose for a long time. The cheek adhesive portions 5L and 5R extend in the left-right direction of the face G from the base of the nose of the face F in a state where the cooling sheet 1 is adhered to the region R. It is preferable that the length L (see FIG. 1) of the cheek adhesive portions 5L and 5R in the direction along the left-right direction is 30 mm or more.

Further, as shown in FIGS. 1 and 3, in the cooling sheet 1 according to the present embodiment, the cheek adhesive portions 5L and 5R include cheekbone corresponding portions 5BL and 5BR corresponding to the cheekbone of the face F. The cheekbone corresponding portions 5BL and 5BR exist within a range of 40 mm or more and 60 mm or less in the left-right direction from the base of the nose of the face F.

Further, the cooling sheet 1 according to the present embodiment includes a nose back adhesive portion 6 adhered to the nose back portion N of the face F in a state of being adhered to the region R of the face F, and the mask contact portion 4 is a nose. It is arranged on both the left and right sides of the back bonding portion 6.

Further, in the cooling sheet 1 according to the present embodiment, the cooling sheet 1 is provided with an avoidance portion 7 which is arranged below the nose back adhesive portion 6 and avoids adhesion of the face F to the nose tip and the ala of nose. The avoidance portion 7 has a shape that is recessed toward the mask contact portion 4 side (upper side). As a result, the avoidance portion 7 avoids adhesion to the tip of the nose and the ala of nose.

Generally, the nose has irregularities and few flat parts, so that it is not suitable for attaching the cooling sheet 1. However, among them, the ala of nose has a curved surface and has steps, so that the cooling sheet 1 is not suitable. By providing the avoidance portion 7 for avoiding the same portion, peeling can be prevented.
