Description

  The present invention relates to patches such as cataplasms and plasters. More specifically, it is a highly convenient patch that can be easily and easily affixed to the affected area without causing the hands to get dirty, and without causing wrinkles on patches such as poultices and plasters. About.

In recent years, as an aging society has progressed, various computers have been used to streamline office work, and as a result, the number of people complaining of pain in the lower back, shoulders, knees, elbows, etc. has been increasing. Etc. are widely used. In general, patches such as poultices and plasters have a structure in which a support, plaster and release sheet are laminated, but it is difficult to peel off the release sheet during use. There was a problem for the person.
In order to improve these, for example, two release sheets are combined at the center of the patch, bent from the joint, and provided with a pull tab portion, thereby making the release sheet easy to peel (Patent Document 1) In addition, the release sheet is provided with a cut line in the shape of a crest and a trough such as a corrugated or saw-tooth shape, and by bending the entire patch, the crest becomes a gripping portion, and the release sheet can be easily peeled off. A patch (Patent Document 2) can be mentioned. The former patch is costly to form the pull tab portion, and the formed pull tab is caught. Further, the latter patch needs to have a rigidity that allows the release sheet to be peeled off when the patch is folded, and is accompanied by certain restrictions on the material of the release sheet.

On the other hand, although it is in the field of adhesive bandages having a disinfecting pad, there is known an emergency adhesive bandage that uses a single peeling thin plate with a broken line-like cut, and pulls it left and right to divide it into two sheets (patent) Reference 3). However, in order to peel off the divided peeling thin plate, an operation such as curving the emergency adhesive bandage itself and a change of hand are necessary, and it cannot be said that the usability (ease of sticking) is excellent.
In the field of patches, there is known a patch (Patent Document 4) excellent in usability (easiness of pasting) that can divide only the release sheet by pulling left and right. The needs of consumers, particularly elderly people who seek ease, are becoming increasingly sophisticated, and there is a need to provide more highly functional patches that enable simpler peeling operations.
JP 7-700751 Japanese Utility Model Publication No. 1-165023 Japanese Utility Model Publication No. 50-133797 JP-A-8-112305

  Accordingly, an object of the present invention is to provide a patch that is superior in usability (ease of sticking) and easy to peel off the release sheet in a conventional patch that is pulled right and left to cut only the release sheet. .

  In order to solve the above problems, the present inventors have divided one or more notches that are opened when the patch is pulled left and right in the vicinity of the position where the release sheet is divided. As a result of further finding out that the peeled release sheet is turned up cleanly, the present invention has been completed.

That is, the present invention includes a stretchable support, a plaster spread on substantially the entire surface of the support, and a release sheet attached to the entire surface of the plaster, and pulls left and right. It is a patch in which only the release sheet is split at the split part, and the split part has an S shape, a wave shape or a saw blade shape, and the patch is pulled in the vicinity of the split part. It is related with the said adhesive patch provided with 1 or 2 or more of cut | notch parts which open.
Furthermore, this invention relates to the said adhesive patch whose cut | notch part is T shape.
The present invention also relates to the above-mentioned patch, wherein the T-shaped vertical bar is parallel to the left and right pulling directions of the patch, and the tip of the vertical bar is arranged toward the dividing portion.
Furthermore, the present invention is a single release sheet having a split part, and only the release sheet is split at the split part due to the difference in elongation between the release sheet and the support simply by pulling the patch left and right. The above-mentioned patch.

The present invention adopts the above-described configuration, so that the release sheet is divided only by pulling the patch left and right, without requiring a peeling start operation such as searching for the edge of the release sheet or the support with a nail, Due to the presence of the cut portion, the end portion of the separated release sheet is turned up well, so that the work of picking and peeling the release sheet becomes extremely easy. Moreover, because part of the plaster is exposed more widely due to good turning up, the exposed part of this more exposed plaster is directly applied to the affected area and is applied without changing the patch (so-called one-touch) Adhesion) becomes even easier.
Furthermore, the usability (ease of sticking) of the patch is further improved by clearly showing on the release sheet and / or support the usage of pulling the patch left and right and sticking it to the affected area with one touch without changing hands. And the patch can be made more sophisticated.
When the patch of the present invention is pulled to the left and right, the release sheet turns up well. First, the release sheet is divided at the dividing portion, and at the same time, an opening is formed at the cut portion, and air is released from the cut portion to the release sheet. It is thought that this air enters between the plaster and encourages the air to turn up.

  In the present invention, the dividing part refers to a part where the release sheet is divided when the patch is pulled left and right. This can be provided at a desired position such as a substantially central portion or a peripheral portion of the release sheet. The dividing portion of the present invention is typically a thin-walled cutting portion that is thinned without penetrating the release sheet, which is also called a so-called half cut, a perforated cut portion in which the release sheet is cut at a predetermined interval, and other weakening lines. And a notch formed in an I-shape or V-shape at the end of the release sheet. In this case, the release sheet is a single release sheet having a divided portion, and only the release sheet is divided at the divided portion due to the difference in elongation between the release sheet and the support simply by pulling the patch left and right. Furthermore, the release sheet in the present invention includes an embodiment composed of two completely separated release sheets. However, the release sheet has a divided portion from the viewpoint of shape retention of the patch, prevention of transpiration of medicinal components, and the like. What is one release sheet is preferable.

  When the dividing part is a thin-walled cutting part or a perforated cutting part, it is provided so as to cross the release sheet at a substantially central part or a peripheral part so that the release sheet is divided. Shapes such as S-shape, wave shape, saw blade shape, and the like, for example, the entire divided part is a saw blade shape, and the portion corresponding to each blade of the saw blade is further a saw blade shape or a wave shape, etc. Combinations may also be used. In particular, an S-shape formed by forming a peak and a valley, a wave shape, a saw blade shape, and the like are preferable. When the distance (stroke) between a certain peak and a peak adjacent to the peak is relatively long (when the number of strokes is small), the section formed after the separation of the release sheet is large and easy to pinch.

  In the present invention, the cut portion is not particularly limited as long as it is open when the patch is pulled, and the opening contributes to the turning up of the release sheet. Typically, the cut portion is linear, T-shaped. Shape, V-shape, C-shape, and the like. Further, it is not necessary that all the cut portions have the same shape, and a plurality of cut portions may be combined. In particular, it is preferable that the T-shaped vertical bar is parallel to the left and right pulling directions of the patch, and the tip of the vertical bar is arranged toward the dividing portion.

  It is preferable that one or two or more of the cut portions are formed in the vicinity of the divided portion and are closed when the patch is not used. Any shape may be used as long as it forms an opening when the patch is pulled left and right, but typically, a cut through the release sheet, a half-cut thin portion, and a perforated cut Etc.

  The patch of the present invention is composed of a support, a plaster and a release sheet, and those conventionally used can be used as described below.

  That is, as the release sheet according to the patch of the present invention, unstretched polypropylene (CPP), stretched polypropylene (OPP), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyethylene, polyester, polyurethane, polyvinyl chloride, Colorless or colored materials such as plastic films such as polystyrene, synthetic resin or synthetic paper, silicon processed paper obtained by silicon processing on synthetic fibers, aluminum foil, and laminated paper obtained by laminating kraft paper with polyethylene or the like are used.

The release sheet preferably has a thickness of 10 μm to 75 μm, preferably 12 μm to 40 μm, and more preferably 15 μm to 35 μm. If the thickness of the release sheet is too small, the release sheet may get entangled with the plaster, or it will be difficult to pick because the release sheet is thin and slippery, and the release sheet will be immediately divided during production, resulting in reduced workability, etc. Moreover, when sticking a peeling sheet on a plaster body, it exists in the tendency for wrinkles to approach a peeling sheet easily. Also, if the release sheet is too thick, the release sheet can be easily picked at the time of peeling, etc., but it becomes difficult to cut, and it becomes difficult to cut the raw sheet at the time of manufacture, and workability and the like tend to be reduced. .
The tensile strength of the release sheet is preferably in the range of 10 g / cm to 140 g / cm, preferably 20 g / cm to 100 g / cm, and more preferably 30 g / cm to 60 g / cm. If the tensile strength of the release sheet is too small, the release sheet will be cut off during the production, making it impossible to continuously apply the release sheet on the plaster, and patches such as poultices and plasters. In the case of putting the product in a packaging bag, the release sheet is easily divided, and the yield tends to decrease. On the other hand, if the tensile strength is too high, it becomes difficult to easily separate the release sheet when used, and the usability tends to decrease.
The tensile strength can be measured by using, for example, a tensile tester AGS-100B (manufactured by Shimadzu Corporation), holding the separation sheet at a distance of 100 mm with a chuck having a width of 50 mm, pulling at 100 mm / min, and breaking. It can be done by measuring the time load.
Furthermore, when the release sheet has a thickness of 10 μm to 75 μm and a tensile strength of 10 g / cm to 140 g / cm, in addition to the above workability and usability, there is also a conflict with the elasticity of the release sheet and the action of the notch provided in the release sheet. Thus, the turn-up is improved and the plaster can be exposed more widely.
Moreover, in order to clarify the tearing method on the left and right portions of the release sheet, a display portion such as a figure such as an arrow, a character, a symbol, or the like may be provided, or may be colored. Using such indications and coloring, for example, by pulling the patch left and right and clearly showing on the release sheet the method of sticking to the affected area with one touch without changing hands, Usability (ease of sticking) is increased. In addition, you may provide the said display part in a support body.

The release sheet may be further embossed. Typically, when peeling the torn release sheet, typically the entire surface of the release sheet or a local location, for example, a location that can be easily picked by hand when tearing the split portion. Embossing is formed at places where it is easy to pick. The shape of the emboss is not particularly limited as long as it can be easily picked by hand without slipping, but can be formed into various other shapes such as a lattice shape, a round shape, a square shape, a star shape, etc. .
The release sheet embossed on the release sheet is partially different in strength, so the turn-up is good, and when the cut part is provided, the embossed unevenness and the cut part combine to make the change more Rich and good turn-up, the exposure of the plaster surface is greater, and the convenience is further enhanced when the release sheet is picked. Furthermore, there is an advantage that the release sheet is less likely to be reattached to the plaster due to the non-planar turning up.

The support according to the patch of the present invention may be a support that is not divided even when the release sheet is divided when the patch is pulled left and right. In addition, when using a single release sheet having a dividing portion as the release sheet, the expansion ratio of the release sheet and the support is such that only the release sheet is divided at the dividing portion when the patch is pulled left and right. The difference is preferably 0.3% or more in order to turn up the release sheet at the time of division.
Examples of the support include elastic materials such as woven fabric, knitted fabric, non-woven fabric, and non-woven paper. Specific materials include natural fibers such as bast fibers such as paper, cotton, cannabis and jute, cellulose fibers such as vein fibers such as manila hemp, animal fibers such as wool, and natural fibers such as protein fibers such as silk fibers and feather fibers. Regenerated cellulose fibers such as rayon and cupra, regenerated fibers such as regenerated protein fibers, semi-synthetic fibers such as cellulose acetate fibers and promix, nylon aramid fibers, polyethylene terephthalate fibers, polyester fibers, acrylic fibers, polyethylene and polypropylene, etc. Polyolefin fiber, polyvinyl alcohol fiber, polyvinyl chloride fiber, polyvinylidene chloride fiber, polyvinyl chloride fiber, polyurethane fiber, polyoxymethylene fiber, polytetrafluoroethylene fiber, polyparaphenylene benzbisthiazole (PBT) fiber, polyimide fiber Etc. are available .
The support is appropriately selected in consideration of physical properties such as thickness, elongation, tensile strength, workability, feel at the time of application, sealing of the affected area, transfer of the drug to the support, and the like.

  The plaster according to the patch of the present invention can be effectively used as a patch for external patch or plaster by containing or adhering a drug to the base material. The plaster contains moisture so that a medicinal effect on the skin can be obtained sufficiently, has adhesiveness, and has moderate cohesiveness that softens even at room temperature or higher and does not remain on the skin. Formed as follows.

  The plaster is prepared by using a thickener, a wetting agent, or the like, and it is desirable that the thickener can stably hold water at 30% to 80% and has water retention. Specific examples include guar gum, locust bean gum, carrageenan, alginic acid, sodium alginate, agar, gum arabic, tragacanth gum, karaya gum, pectin, starch and other microbial systems, sansan gum, acacia gum and other microbial systems, gelatin, collagen and the like. Natural polymers such as animal systems, cellulose systems such as methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose sodium, semi-synthetic polymers such as starch systems such as soluble starch, carboxymethyl starch, and dialdehyde starch, polyvinyl alcohol, polyvinyl pyrrolidone, Vinyl-based materials such as polyvinyl methacrylate, acrylic-based materials such as polyacrylic acid and sodium polyacrylate, other polyethylene oxide, methyl vinyl ether / Water-soluble polymers of a synthetic polymer such as water maleic acid copolymers and the like are suitably used.

  In particular, sodium polyacrylate is preferable. This is because the gel strength is strong and the water retention is excellent. Furthermore, sodium polyacrylate having an average degree of polymerization of 20000 to 70000 is preferred. As the average degree of polymerization becomes smaller than 20000, the thickening effect becomes poor and sufficient gel strength tends to be obtained. As the average degree of polymerization becomes larger than 70000, the thickening effect becomes too strong and workability tends to decrease. is there. Further, by using two or more kinds of the water-soluble polymers in combination, for example, a polymer complex can be formed with a strong ionic polymer of sodium polyacrylate, and an elastic gel with higher gel strength can be obtained.

  Polyhydric alcohols such as glycerin, propylene glycol and sorbitol as wetting agents, and kaolin, zinc oxide, talc, titanium, bentonite, aluminum silicate, titanium oxide, zinc oxide, aluminum metasilicate, calcium sulfate, calcium phosphate as fillers Etc. may be added. Further, as a solubilizer or absorption promoter, propylene carbonate, crotamiton, 1-menthol, mint oil, limonene, diisopropyl adipate, etc., and as a medicinal aid, methyl salicylate, glycol salicylate, l-menthol, thymol, mint oil, Nonyl acid vanillylamide, pepper extract, etc. may be added. Furthermore, you may add a stabilizer, an antioxidant, an emulsifier, etc. as needed.

  In addition, you may add a crosslinking agent, a polymerization agent, etc. as needed. The plaster can be strengthened and water retention can be imparted. This crosslinking agent and polymerization agent are appropriately selected according to the type of thickener and the like. For example, when polyacrylic acid or polyacrylate is applied to the thickener, compounds having at least two epoxy groups in the molecule, hydrochlorides such as Ca, Mg, Al, sulfates, phosphates, Inorganic acid salts such as carbonate, organic acid salts such as citrate, tartrate, gluconate and stearate, oxides such as zinc oxide and anhydrous silicic acid, hydroxides such as aluminum hydroxide and magnesium hydroxide A polyvalent metal compound such as is preferably used. In addition, when polyvinyl alcohol is applied to the thickener, adipic acid, thioglycolic acid, epoxy compound (epichlorohydrin), aldehydes, N-methylol compound, Al, Ti, Zr, Sn, V, Cu, B, Cr Complexes such as compounds such as are preferably used.

  Further, when polyvinylpyrrolidone is applied as the thickener, methyl vinyl ether / maleic anhydride copolymer, polyacid compound or alkali metal salt thereof (polyacrylic acid, tannic acid and derivatives thereof) and the like are preferably used. Moreover, when polyethylene oxide is applied to the thickener, perchioside, polysulfone azide and the like are preferably used. In addition, when a methyl vinyl ether / maleic anhydride copolymer is applied to the thickener, polyfunctional hydroxy compounds, polyamines, iodine, gelatin, polyvinyl pyrrolidone, iron, mercury, lead salts and the like are preferably used. When gelatin is used as the thickener, aldehydes such as formaldehyde, glutaraldehyde, and dialdehyde starch, diepoxides such as glyoxal and butadiene oxide, diketones such as divinyl ketone, and diisocyanates are preferably used.

  When sodium polyacrylate is applied as the thickener, a polyvalent metal salt such as lithium hydroxide, zinc hydroxide, aluminum hydroxide or sodium borate is preferably added as a crosslinking agent. In particular, zinc salts and aluminum salts are preferred. Cross-linking reaction is promoted. The concentration of the polyvalent metal salt added as the crosslinking agent is preferably 0.5 to 1.5 equivalents per 1 equivalent of the thickener (or water-soluble polymer). If the concentration of the polyvalent metal salt is too low, the reaction will be too slow and the gel strength will tend to be low.If the concentration of the polyvalent metal salt is too high, the reaction will be too fast, resulting in non-uniform gelation and workability. It tends to decrease.

  As a poultice, it has good skin adhesion, enhances skin absorption of active ingredients, contains as much water as possible, takes heat away from the skin when the water in the plaster evaporates, This calorific value gives a refreshing sensation, and the stratum corneum is hydrated by water molecules evaporating from the inside, promoting absorption of the drug, being free from room temperature or a temperature around it, and not painful when peeling off. For example, no stains remain, no stickiness. For this reason, the plaster comprises a thickener 5 wt% to 20 wt%, preferably 10 wt% to 15 wt%, a wetting agent 5 wt% to 40 wt%, a filler 20 wt% or less, and water 10 wt% to 80% by weight, solubilizer 0-8% by weight, drug 5% by weight or less, preferably 0.5% -5% by weight.

  Moreover, when applying to a plaster etc., as this base material, what has an acrylic copolymer, an ABA type | mold block copolymer, an alicyclic petroleum resin, and a softener is used suitably. . Further, AB type block copolymer, other polybutene rubber, butyl rubber, silicone rubber, natural rubber, styrene-butadiene copolymer, NBR polyisobutylene, polyalkyl acrylate, synthetic isoprene, and other thermoplastic elastic agents, and terpene resins , Petroleum-based resins, rosin, hydrogenated rosin, tackifiers such as rosin / hydrogenated rosin ester, animal and vegetable oils such as liquid paraffin, olive oil, soybean oil, beef tallow, and tallow, polybutene, liquid polyisobutylene, lower isoprene, Adhesive strength / holding strength adjusting agents such as wax, fillers such as titanium oxide, zinc oxide, aluminum metasilicate, calcium sulfate, and calcium phosphate are blended.

  As the ABA type block copolymer, a block copolymer of a monovinyl-substituted aromatic compound A and a conjugated diolefin copolymer B is preferably used. Specifically, Califlex TR-1101, Califlex TR-1107, Califlex TR-1111, etc. manufactured by Shell Chemical Co., Ltd., Solprene 418, Solprene 311, etc. manufactured by Philippe Petroleum, and the blending amount thereof are in the plaster composition.

The patch of the present invention can be used as a cold compress without containing any drug.

Hereinafter, the patch of the present invention will be described in more detail with reference to the drawings, but the present invention is not limited to these drawings.
The patch of the present invention is typically a patch as shown in FIG. That is, it includes a support 2 having elasticity, a paste 3 spread on substantially the whole surface of the support 2, and a release sheet 4 attached on the entire surface of the paste 3, It is a patch 1 in which only the release sheet 4 is divided at the dividing portion 10 only by pulling, and a plurality of cut portions 20 are provided in the vicinity of the dividing portion 10. In the same figure, the parting part 10 is a saw-blade perforated cutting part, located in the approximate center part of the patch 1, and the number of strokes is 3.5. In addition, after the separation of the release sheet 4, a part of the cut portion 20 is hung on the portion that becomes the slice 5. The notch 20 has a T-shape, the T-shaped vertical bar is parallel to the left and right pulling direction of the patch 1 (left-right direction in FIG. 1), and the tip of the vertical bar faces the dividing part 10. It is arranged.

  When both ends of the patch 1 are gripped and the release sheet 4 is pulled left and right together with the support 2, the release sheet 4 can be divided by the dividing portion 10. Further, at this time, the cut portion 20 formed in the vicinity of the dividing portion 10 is opened, and air enters between the release sheet 4 and the paste 3 through the opening, and this air is detached from the paste 3. To help. Moreover, the cut | notch part 20 torn makes the bending of the peeling sheet 4 very easy. Since the plaster body 3 is exposed to a greater extent, the section 5 of the peeled release sheet 4 is peeled off while the exposed plaster body 3 is applied to the affected area, and the patch 1 is adhered to the affected area. As a result, the plaster 3 can be exposed greatly and the release sheet 4 can be easily peeled off more easily than before, so that the hands 1 are not soiled and the patch 1 is not wrinkled. can do.

The patch of the present invention includes various modes shown in FIGS.
In FIG. 2, similarly to the embodiment of FIG. 1, the T-shaped cut portion 20 is arranged such that the T-shaped vertical bar is parallel to the left and right pulling directions of the patch, and the front end of the vertical bar faces the dividing portion. However, it is different in that one notch 20 is entirely located inside one piece 5 (within the width of each of the left and right tips of a saw blade shape).

In FIG. 3, the linear cut portion 20 is disposed in the vicinity of the bottom of the triangular portion of the section 5 and is disposed perpendicular to the right and left tension directions of the patch.
In FIG. 4, the dividing portion is a corrugated half cut, and the T-shaped cut portion 20 is arranged in the same manner as in FIG.

The tip of the vertical bar is arranged toward the dividing portion in parallel with the left and right pulling directions of the patch.
In FIG. 7, the dividing part has a shape combining a straight line and a curved line, and a T-shaped cut part 20 is arranged.
In FIG. 8, the dividing portion has a shape combining a linear shape and a saw blade shape, and a T-shaped cut portion 20 is disposed.
In the patch shown in FIGS. 5 to 8, since the slice 5 is formed relatively large, it is easy to grip when peeling the release sheet.

  The patches shown in FIGS. 9-12 represent a further embodiment. In FIG. 9, the angle of the crest portion 10 of the dividing portion 10 is large, and the cut portions 20 are arranged in one row along the center line of the dividing portion 10, and are further arranged to add one row in the section 5. . In FIG. 10, the angle of the crest portion of the dividing portion 10 is about 70 to 90 degrees, and two cut portions 20 are arranged in the crest portion in parallel to the center line of the dividing portion 10 and one perpendicularly. 11 and 12, the three cut portions 20 are arranged in the mountain portion in parallel to the center line of the dividing portion 10, and there is a mode in which two ridges are connected to one ridge line of the mountain portion (FIG. 11) and 1 It is an aspect (FIG. 12) with the connection of a location.

Ten healthy adults aged 50 to 70 have both ends of the patch provided with the cut portions having the shapes and arrangements shown in FIGS. 1 to 3 and pulled left and right. At that time, “ease of picking the release sheet” In addition, the “easiness of sticking” was scored according to the following criteria as to how preferable it is compared with the comparative example (the one without the cut portion in FIG. 1). The average value of the scoring results is shown in Table 1.
