Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling patch sheet for use by sticking to skin, and in particular,
It relates to a heat-cooling sheet to be attached to the forehead.

[0002]

2. Description of the Related Art Generally, a water pillow, an ice sac, etc. are used to cool the heat of the head when heat is generated. In recent years, a product in which a refrigerant is stored and wound around a head to be fixed is also commercially available.

However, with a water pillow or an ice sac, it is troublesome to repeat the operations of making ice in advance, putting it in an ice sac bag or a water pillow and using it again when the ice melts. Also, the one using a refrigerant is simpler than a water pillow or an ice sac, but it needs to be frozen in advance, and since the only way to do it in a general household is in a freezer, it occupies more space than necessary. It will be that.

Therefore, as a simpler heat-cooling tool, a stick-type heat-cooling sheet has been commercially available. this is,
Basically, it is a laminate having the same structure as a cooling patch used by sticking it to the skin of the affected area and consisting of a support, a plaster and a release liner in order from the surface. The plaster has a base mixed with a cooling agent such as peppermint oil and menthol.

In such a heat-cooled sheet, the manufacturing method is the same as that for a general poultice, and the plaster is spread and applied on the surface of the support, and a release liner is attached to the plaster surface side, and then the laminate is laminated. Punch and cut the body into a rectangle of appropriate size.

Also, in use, like the case of general poultices, the liner is peeled off and the plaster surface is placed on the skin side, and it is simply attached to the forehead, so replacement is easy and very simple. is there. Also, since plaster has a certain degree of adhesiveness,
It is hard to shift even during use during sleep.

[0007]

However, since the shape of the conventional heat-cooled sheet as described above is a rectangle similar to that of a general poultice, when it is attached to the forehead, it does not correspond to the curved surface of the forehead. It is not possible to make a perfect fit, and wrinkles and gaps are created. If there are such wrinkles or gaps, they tend to shift or come off during use.

Further, since the hairline of the forehead is usually arcuate, it is difficult to fit the forehead if the upper side of the sheet coming to the hairline side of the hair at the time of sticking is hard to fit, and further peeling off when the hair is involved. Not only is it easier, but there is also the problem that the plaster adheres to the hair. If a small sheet is used to avoid this, the cooling area will also be small, and good heat cooling cannot be performed.

In view of the above problems, the present invention provides a heat-cooled sheet and a method for manufacturing the same that fits on the forehead to obtain a good heat-cooling effect as compared with the prior art, and also reduces misalignment and dropout during use. To aim.

[0010]

In order to achieve the above object, in the heat-cooled sheet according to the invention described in claim 1,
A heat-cooled sheet for sticking a forehead, which is spread-coated on a support, and has a substantially fan-like shape whose two parallel sides in the longitudinal direction are curved toward the head side when sticking the forehead. It is what

Since the heat-cooled sheet of the present invention is substantially fan-shaped and has two curved sides parallel to each other in the longitudinal direction, it can be attached to the curved surface of the forehead during use without forming wrinkles or gaps. It is less likely to slip or peel off during use than conventional ones. In addition, since the curvature follows the hairline at the time of sticking, the plaster surface does not touch the hair and good heat cooling is performed in the forehead region.

In the method for producing a heat-cooled sheet according to the second aspect of the present invention, a step of spreading the plaster on the surface of the support and attaching a release liner to the plaster surface side,
In the method for producing a heat-cooled sheet having a step of cutting a laminate of the support, plaster and release liner into a predetermined adjoining punched shape, the punched shape has two parallel sides in the longitudinal direction. The blade shape is a substantially fan-like shape that is curved, and in the step of cutting into the adjacent punched shape, a blade mold having curved portions corresponding to the two sides is used.

In the method for producing a heat-cooled sheet according to the present invention,
In order to punch and cut a laminate composed of a support, a plaster and a release liner into a substantially fan shape, a blade-shaped fan having a curved portion corresponding to two sides in the longitudinal direction is used. In such a blade type for push-cutting, when a load is applied to the blade, a point load is lighter than a line load.

In the present invention, since the point load is applied by the curved blade during push-cutting, the sharpness and holding of the blade are improved as compared with the conventional case where only a straight blade for punching a rectangular sheet is used. This improves the quality and reduces the frequency of blade replacement, which contributes to cost reduction for manufacturing equipment.

The plaster used for the heat-cooled sheet of the present invention has a cooling and cooling effect in addition to a composition containing only water and having no odor or irritation, for example, peppermint oil, menthol, or other materials. A substance in which a drug such as an essential oil component of a plant is contained in a base such as a shape-retaining agent or an adhesive is used.

Specific shape-retaining / adhesive agents that can be used as a base include, for example, sodium carboxymethylcellulose, sodium methylcellulose, polyvinyl alcohol, sodium alginate, sodium polyacrylate, polyvinylpyrrolidone, gelatin and carbopol. Thickeners, natural rubber, synthetic rubber,
Examples thereof include styrene-isoprene-styrene block copolymer-based, silicone resin-based, and polyvinyl ether-based adhesives. Further, as a humectant, glycerin, propylene glycol, sorbitol and the like can be used.

The support used in the heat-cooled sheet of the present invention mainly serves to hold the plaster,
Although those conventionally used for poultices can be used, those which adhere to the plaster and do not have backing are desired. Further, it is preferable to use a material having elasticity and breathability for enhancing a feeling of fitting to the skin. Specific examples include, for example, flannel, woven fabric, knitted fabric, non-woven fabric, aluminum film, plastic film simple substance or composite, and the like.

As the release liner used in the heat-cooled sheet of the present invention, those which have been conventionally used for general poultices can be used. Examples thereof include glassine paper, polyethylene terephthalate, polypropylene, polyethylene, aluminum film and This is silicon processed,
However, it is desirable that the product has excellent adhesiveness to the plaster and excellent quality retention.

FIG. 1 shows an example of an embodiment of the present invention.
Shown in As shown in the plan view (a), this is a substantially fan-shaped heat-cooled sheet 1 in which two parallel sides (L ₁ , L ₂ ) in the lateral (longitudinal) direction are curved upward in the figure. Is. Since this sheet 1 is worn on the forehead, the vertical side d is 3 to 7 cm and the horizontal side (L
₁ , L ₂ ) has a size of about 10 to 20 cm.

The structure is as shown in the sectional view (b):
The plaster 3 is spread and applied on the surface of the support 2, and the release liner 4 is attached to the plaster 3 surface side. At the time of use, the release liner 4 is rolled up, and as shown in FIG. 1 (c), the surface of the plaster 3 is brought into contact with the skin of the forehead 5, and the protruding side of the curved portion is attached to the head.

As described above, the heat-cooled sheet 1 has a substantially fan shape with two longitudinal sides (L ₁ and L ₂ ) being curved, so that it does not form wrinkles or gaps along the curved surface of the forehead 5. Since it can be attached by sticking, it keeps a good fit during use and avoids slipping and peeling off.

Next, an example of the method for producing the heat-cooled sheet of the present invention will be described below with reference to FIG. FIG. 2 (a)
It is process drawing which shows the whole manufacturing process. Here, a water-soluble polymer as a base containing an essential oil component such as peppermint oil was used as a plaster 13, a non-woven fabric was used for the support 12, and a polypropylene film was used for the release liner 14.

First, the plaster 13 is spread on the surface of the strip-shaped release liner 14 so as to have an appropriate thickness, and the strip-shaped support 12 is laminated thereon. When the laminated body is fed in a state where the roller R portion is tension-pressed, the spread application of the plaster 13 on the surface of the support 12 is brought into a more stable contact state, and the strip-shaped sheet 10 is fed to the punching and cutting process. Be done.

The punching and cutting here is performed by using a roll-type punching machine 17 to form adjacent punches. The roll-type punching machine 17 has a plurality of cutting blades 18 _{x of the} same type corresponding to the punching shape continuously provided on the peripheral surface in the rotation direction. By feeding the strip-shaped sheet 10 while rotating the cutting blades 18 _x , Cutting blade 18 at the contact portion with the sheet 10
_The strip-shaped sheet 10 is pushed out every time _x comes and is sent as individual heat-cooled sheets 11 which are sequentially punched and cut into a predetermined shape.

In the present manufacturing process, in order to make efficient and adjacent punching shapes with little waste of material, one cutting line orthogonal to the feeding direction separates unit sheets that are adjacent to each other in the front-rear direction and the left-right direction from one side of both sheets. The cutting blade 18 _x was continuously installed so that That is, FIG.
A cutting blade having a blade shape corresponding to the cutting line 18 _y shown by the solid line in the schematic view of the surface of the sheet (not yet separated) sent in the band shape immediately after cutting shown in (b) _18x .

As described above, since the heat-cooled sheet of the present invention has a substantially fan shape having two curved parallel sides,
The entire blade die of the roll-type punching machine 17 is in a state in which the target substantially fan shapes are adjacent and continuous, and the cutting blade 18 _x has a curved portion corresponding to the two sides. Since such a curved cutting blade has a load at the time of push cutting as a point, it has better holding performance than a linear cutting blade for rectangular punching in which the load becomes a line, and the life of the blade is extended.

As described above, when the strip-shaped sheet 10 is fed into the roll-type punching machine 17, the substantially fan-shaped sheet 1 is sequentially formed.
Since it is punched and cut into 1 and sent, it is possible to pack an appropriate number of pieces into a product.

If a sheet with the peripheral edge pressed is desired, a die pressing step may be provided as a step prior to the step of cutting the sheet into adjacent punched shapes by the roll punching machine 17. For example, as shown in FIG. 2A, a pressing roll 15 is provided in front of the roll punching machine 17, and the band-shaped sheet 10 is fed to the roll punching machine 17 after the die pressing by the roll 15.

A presser die 16 _x corresponding to the blade of the roll punching machine 17 is provided on the peripheral surface of the presser roll 15, and as shown in the plan view (b) of FIG. Each time the pressing die 16 _x comes in contact with the strip-shaped sheet 10 by rotation, the substantially fan-shaped groove-shaped pressing portion 16 _y is sequentially formed on the strip-shaped sheet 10.

Presser roll 15 and roll-type punching machine 17
The positional relationship with and may be set in advance so that the cutting line 18 _y finally overlaps the center of the groove-shaped pressing portion 16 _y . Heat-cooled sheet 1 manufactured through such an embossing process
As shown in the cross-sectional view (c) of FIG. 2, the groove-shaped pressing portion 16 _y , that is, the peripheral portion of each sheet 11, has the support 12 pressed toward the release liner 14 and the plaster 13. Is running away.

The heat-cooled sheet according to the present invention does not necessarily have to be peripherally pressed, but by this peripheral pressing, the plaster 13 is contained by the support 12 and the release liner 14. Has become. Therefore, as compared with the one in which the peripheral edge is cut as described above, the peripheral cut surface is exposed as shown in FIG.
It is considered to be effective in maintaining the quality of the plaster.

In addition, in the heat-cooled sheet having the peripheral edge pressed in this way, when the support at the peripheral edge adheres to the forehead skin when it is adhered to the forehead, the plaster will still adhere to the support and the skin. As it is contained, there is no part exposed to the outside. Therefore, leakage of the salve from the peripheral portion during use can be avoided, and therefore, the heat-cooled sheet of the present invention used at a portion close to the eyes, such as the forehead, is preferably provided with peripheral pressing.

The curvature of the heat-cooled sheet of the present invention is
It may be a gentle one that is attached to the curved surface of a general person's forehead when it is attached. Also, the width and length may be set so that the area corresponds to the forehead area, but the area of the forehead also differs depending on the individual and the stage of development from child to adult, so the user may Various sizes may be provided so that an appropriate one can be selected.

[0034]

As described above, the heat-cooling sheet of the present invention has a substantially fan shape with two parallel sides in the longitudinal direction curved, so that it fits on the forehead and a good heat-cooling effect is obtained, and it is in use. This has the effect of reducing slippage and dropout.

Further, in the method for producing a heat-cooled sheet of the present invention, in a step of punching and cutting a laminate of a support, a plaster and a release liner in a substantially fan shape having two parallel sides in the longitudinal direction curved. Since the blade mold having the curved portions corresponding to the two sides is used, the cutting blade itself has a long holding time, and the life of the blade mold is extended, so that the number of blade replacements is reduced and the cost is reduced.
