Description

  The present invention relates to a patch. More specifically, the present invention relates to a patch that can be easily peeled off and can be easily applied to an affected area.

  Conventionally, patches such as poultices (paps) have been widely used as a treatment for pain in the shoulders, elbows, knees, ankles, etc. One with a release sheet having a cut line (Japanese Patent Laid-Open No. 8-112305) and further one with two release sheets (Japanese Patent Laid-Open No. 2002-65726) are provided so as to improve ease of use and convenience. Are known.

  However, these release sheets still have difficulty in peeling off from the plaster surface, and none of the applied affected areas and application cases have improved convenience, and a more excellent patch is desired. Specifically, the one attached with one release sheet, which is commonly used, is a thing that is very inconvenient for the elderly, etc., because the corners of the release sheet are searched with nails many times. .

  In order to improve this, it has been proposed that one release sheet has a cut portion and is peeled off by pulling left and right. However, when pulled left and right, the divided part does not turn over, I couldn't pick it up. Moreover, although it is preferable when applied to the knee, the convenience effect was hardly exhibited when applied to the shoulder, the back, and the like. In addition, when applying to the shoulder or to other people on the back, there are many cases where it is desirable to apply to the affected area with a preferable application area. It was. Of course, there is a case where it is desired to apply to a knee or the like without being deformed.

Further, a sheet with two release sheets attached has been proposed. However, since there are alternately convex and concave knobs of the same size and shape in parallel positions, the lower knobs are accidentally pinched. There was a problem and it was a problem. Moreover, it was not considered at all to divide the release sheet by pulling left and right to expose the plaster surface.

  Under such circumstances, there has been a demand for a patch that can more easily peel off the release sheet of the patch and can be more easily and accurately applied to the affected area. Furthermore, there has been a demand for a patch with use selectivity that can be easily peeled off and pasted by an appropriate method for each application site and case.

  The present invention has been made in view of the above problems. The purpose is to provide a patch that can be easily peeled off from the release sheet, can be easily and accurately applied to the affected area, and can be selectively used depending on the application site or case. It is in.

  As a result of diligent research and searching to achieve the above purpose, the release sheet having two peeling functions was laminated on the plaster laminated with the support having elasticity. The present invention has found that an excellent patch can be obtained that has an easy-to-peel operation of the release sheet, can be easily and accurately applied to an applied affected area, and has a use selectivity for peeling that can be selectively used for each application site and case. I went to.

That is, according to the present invention, a stretchable support, a paste laminated on substantially the entire surface of the support, and an embossed portion that covers the entire surface of the paste substantially in half are formed. A patch comprising a first release sheet and a second release sheet, wherein the first release sheet is folded at an end so as to form a valley-like folded portion at a substantially middle position of the patch. And having a first edge portion having a convex edge shape, the second release sheet being overlaid on the first knob portion, the first release sheet and the second release sheet Is a dark color where the first release sheet and the second release sheet overlap in the center overlap part where the first release sheet and the second release sheet overlap each other , having a dot-like colored part over the entire surface and portions, appears that dark portions said first release sheet and said second release sheet overlaps in triplicate And wherein,
The patch is
(1) By holding both ends of the patch and pulling left and right,
The release sheet is divided to expose the plaster surface to be applied; and (2) by having a knob formed on the release sheet and peeling it off,
The ability to expose the plaster surface to be applied,
And a patch characterized by comprising the following.

  According to the present invention, the peeling operation of the peeling sheet is easy, it can be easily and accurately attached to the application affected part, and it has the use selectivity of peeling and application method that can be used properly for each application site and case.

  Hereinafter, although an example of an embodiment of the present invention is explained, the present invention is not limited to the following embodiment. The patch of the present invention comprises a stretchable support, a paste laminated on substantially the entire surface of the support, and two release sheets (: A first release sheet and a second release sheet), and has two peeling functions when peeling the release sheet.

  (1) One is a function of separating the release sheet by pulling left and right holding both ends of the patch, and exposing the plaster surface to be applied, and sticking the exposed plaster surface to the affected area, The affected part can be attached simply by picking each divided sheet and pulling it left and right. Thereby, especially when applying by sticking to a knee, an ankle, etc., it is easy to peel off without dirtying the hand, it is easy to apply to the affected part, and it is convenient and suitable.

  On the other hand, (2) has a function of exposing the plaster surface to be applied by holding and removing the knob formed on the release sheet, and sticking the exposed plaster surface to the affected area The affected part can be attached simply by holding the part and pulling it left and right. Thereby, especially when applied to a shoulder, an elbow, etc., it is easy to peel off, it is easy to apply to an affected part, and it is convenient and suitable.

  In addition, this method is suitable when it is desired to apply to the affected area with a preferable application area, regardless of the application location. Also, when it is desired to apply without deviation as much as possible, the single sheet is peeled off and the plaster surface is attached to the affected area, and the remaining sheets are applied. You can stick more accurately by pulling. For example, the second release sheet on the upper side is peeled off, the first release sheet part that has not been peeled off is held by hand, and the exposed plaster surface is affixed to the affected part. At this time, even if the position is shifted, it can be lifted up again and re-applied, and the operability is good. In addition, since a part of the plaster surface is affixed to the affected area and the remaining sheet is pulled from the fixed state, it can be neatly applied to the affected area without shifting and without wrinkles.

  Since the patch of the present invention has the above two peeling functions, it has an advantage that a patient can select an application method in a timely manner at the time of use. If these two functions are provided, it is an excellent patch that can be applied to all affected parts (shoulder, elbow, knee, ankle, waist, etc.) where the patch is generally used.

  The patch of the present invention has two release sheets that cover the entire surface of the plaster by roughly dividing it, and is composed of a first release sheet and a second release sheet. The first release sheet is not particularly limited, but covers the plaster surface from the edge of the patch, and is folded at the end so as to form a valley-like folded portion at a substantially middle position of the patch. The first release portion having a first edge portion is preferable, and the second release sheet is overlaid on the first knob portion, and preferably has a convex edge shape. It is more preferable to have two picking parts.

  As a result, (1) when the release sheet is peeled off by holding the both ends of the patch and pulling it left and right, the conventional release sheet has little warping and may not be picked. Then, since the first release sheet has a folded first knob portion, it can be reliably peeled off with the knob portion, and the second release sheet is in a state of overlapping the first release sheet, Can be removed without problems. In addition, if the second release sheet has a second knob, it is easier to pick.

  Further, the folded portion of the first release sheet is preferably formed so as to form a valley line shape at a substantially middle position of the patch, and when it is pulled left and right, it can be easily divided into left and right. If the folded portion is formed so as to be substantially deviated from the middle, it may be impossible to divide it cleanly.

  On the other hand, (2) When applying by peeling off the gripping part formed on the release sheet, it can be peeled off with the gripping part and applied to the affected part without any problem for the same reason as above. it can.

  In addition, it is preferable that the first knob part and the second knob part are arranged so that the protrusions at the edge of each other are shifted from each other, from the valley-shaped folded part to the protrusion edge. It is better that the length of the second knob is 3 mm or longer, preferably 4.5 mm or longer, more preferably 4.9 mm or longer than the first knob. By this, when having a knob part, both knobs are not picked at the same time, and the second knob part on the upper second release sheet is formed longer so as to cover, Without accidentally picking the lower first knob, the second knob can be securely picked and peeled off.

  Furthermore, the length from the valley-like folded portion to the convex edge is 5 to 20 mm in the first knob and 10 to 25 mm in the second knob. It is more desirable. This length means the length to the top of the convex shape, and indicates the length from the valley line of the folded portion to the longest point in the vertical direction. If the first picking part is formed shorter than 5 to 20 mm, it is difficult to pick it with a finger. If it is too long, the first picking part may be picked by mistake when picking the second picking part. On the other hand, if the second picking part is formed shorter than 10 to 25 mm, the first picking part may be picked by mistake when picking the second picking part. When using the function, the plaster surface may not be accurately exposed.

  Further, it is better that the convex shape of the first knob and the convex shape of the second knob are different. Since it can be visually confirmed by the different shape, there is no possibility of picking a different knob by mistake. Moreover, since the shape is different, it is easy to explain in a packaging bag or a manual. For example, as shown in FIGS. 1 to 6, if a trapezoidal first picking part (such as Mt. Fuji) and a semicircular second picking part are provided, it is easy to distinguish and explain (refer to FIG. 6 etc.). ).

Moreover, although it does not specifically limit, the number of a 1st knob | pick part and a 2nd knob | pick part is good to form 1-4 pieces each, and it is more preferable to form 1-3 pieces each. Although not particularly limited, and a first knob portion the size of the second knob portion, finger packed as 2cm wide or more, it is preferable that provided in 2.5 cm ² or more.

  Further, the release sheet of the patch of the present invention is preferably embossed, and this is preferable because the finger does not slip when the patch is pulled to the left or right or when the knob is picked. Further, in the case of a flat release sheet, the overlapping portion may be in close contact, but an embossed release sheet is preferable because there is no such thing.

  Moreover, although not particularly limited, it is more preferable that the first release sheet and the second release sheet of the patch of the present invention are colored in the entire surface or in the form of dots. Further, it is more preferable that the entire surface is colored or dot-like, not partial. This makes it easy to distinguish the white plaster surface from the colored release sheet surface. Further, when the release sheet falls on the floor, it is easy to distinguish because the entire surface is colored, and it does not slip on the release sheet by mistake. In addition, a partially colored sheet may be formed with a shifted colored portion, but a completely colored sheet is easy to manufacture and has no trouble such as printing misalignment. In addition, it is better that the coloring is formed so as to have translucency, and as a result, as shown in the explanatory diagram of FIG. The color part appears and the knob is easily visible.

  Here, as the release sheet, plastic films such as polypropylene, polyethylene terephthalate, polyethylene, and polyester, synthetic paper, processed paper, aluminum foil, and the like are used. The thickness of the release sheet is 10 μm to 80 μm, preferably 20 μm to 40 μm. If it is too thin, it will be difficult to pick and there will be a problem in manufacturing workability, and if it is too thick, there will be problems such as sheet cutting work in manufacturing. But it is unsuitable.

  As the support, a stretchable material such as a nonwoven fabric, a woven fabric, or a knitted fabric is used. The patch of the present invention needs to be stretchable so that it can be peeled off by pulling left and right to split the release sheet. Although not particularly limited, the 50% modulus (kg / 2.5 cm) in the pulling direction (usually the direction in which the long side is stretched) is preferably 0.03 to 0.18, and 0.05 to 0.15. More preferred is 0.05 to 0.1.

  The plaster is not particularly limited as long as the patch of the present invention is pulled to the left and right to split the release sheet and peel it off. What is used for patches, such as these, can be used.

  The patch of the present invention is not particularly limited, and includes patches such as poultices, plasters (plasters), tapes, cooling sheets, pressure ulcer sheets, cosmetic use sheets, etc., which can be used in any case. is there. In particular, it is more effective for cataplasms.

Hereinafter, further examples will be described.
"Example 1"
After adding a solution in which carboxymethyl cellulose sodium is dispersed in glycerin to purified water, gelatin is added and dissolved. Next, a solution obtained by partially neutralizing sodium polyacrylate, sodium polyacrylate, aluminum hydroxide, polyoxyethylene sorbitan trioleate in glycerin was added and kneaded sufficiently, and then ketoprofen was added in advance to N-methyl- After adding a solution dissolved in 2-pyrrolidone and l-menthol, components of a pH adjuster, sodium edetate, thymol, and silicic anhydride were added and kneaded sufficiently to obtain a ketoprofen-containing plaster. The obtained plaster is spread on a polypropylene nonwoven fabric support (coating thickness: 0.8 mm) and covered with two release sheets (first release sheet and second release sheet) of polypropylene film (embossed). Then, it was cut and adjusted to 10 cm × 14 cm to prepare a patch (a patch).

  The shape (structure) of the release sheet was configured as shown in FIGS. That is, the first release sheet is folded at the end so as to form a valley-shaped folded portion at a substantially middle position of the patch, and has a first knob portion having a trapezoidal convex edge shape. The length from the valley-like folded portion to the convex edge is formed to be 15 mm, and the second release sheet is superimposed on the first knob and has a semicircular convex edge shape. , Having a second knob part, and forming a length from the valley-like folded part to the convex edge to 20 mm, and the first knob part and the second knob part are located between the convex parts at the edges of each other. However, they were arranged so as to be shifted from each other, and the length from the valley-like folded portion to the convex edge was formed so that the second knob was 5 mm longer than the first knob.

"Example 2"
It was prepared according to Example 1 except that light blue dot printing was performed on the entire surface of the two release sheets. As a result, the overlapping portion at the center of the patch appears shaded as shown in the explanatory diagram of FIG.

“Comparative Example 1”
It was prepared according to Example 1 except that the release sheet was one sheet (10 cm × 14 cm) and the plaster surface was covered with this.

"Comparative Example 2"
A release sheet was prepared according to Example 1 of the present invention except that a release sheet was formed according to Example 1 of Patent Document 1 "Japanese Patent Application Laid-Open No. 8-112305".

“Comparative Example 3”
A release sheet was prepared according to Example 1 of the present invention, except that a similar shape was formed according to FIG. 2 of Patent Document 2 “Japanese Patent Application Laid-Open No. 2002-65726”.

“Comparative Example 4”
The first release sheet was prepared according to Example 1 of the present invention, except that the first pick part was cut and removed to obtain a release sheet (10 cm × 7 cm, rectangular) having no folded part or knob part.
