DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging bag for storing a medicated patch therein and a tool for attaching the medicated patch to a shoulder or a waist by itself.

[0002]

2. Description of the Related Art Conventionally, a plastic fastener has been frequently used as a means for cutting off a part of the periphery of a plastic four-side seal bag or the like having a four-sided seal and opening the opening, and then sealing the opening so as to be openable.

Further, a single line or a plurality of lines of perforations are provided at the upper end of the plastic fastener and the bag in parallel with the plastic fastener, or a V-shaped or I-shaped notch is provided at a seal portion above the plastic fastener. Provided packaging bags are also used.

In order to take out the packaged articles, these bags are usually cut at the sealing portion at the upper end of the sealed bag and the portion where the plastic fastener is installed, and the bag is opened at a perforation or a notch. For those provided with guidance treatment, after cutting according to the perforation or notch, the plastic zipper is then disengaged and the packaged article is taken out from the inside, and the article is again put into the bag. When storing, after putting in a bag, the bag can be resealed by fitting a plastic fastener, and articles can be stored for a long period of time.
Such bags are often used for storing patches.

[0005] A patch such as a plaster or a poultice having a pressure-sensitive adhesive layer formed by dissolving or dispersing a drug in a tacky polymer composition on the surface of a support such as a nonwoven fabric or a plastic film is used. When sticking to an affected area such as a shoulder or a waist, it is often difficult to stick well because the adhesive layers of the plaster or cataplasm adhere to each other. In particular, there is a drawback that the elderly and young children are inconvenient and their tendency is high.

In order to solve this drawback, the release protective film to be applied on the adhesive layer of the adhesive patch is made of two films, or a broken line or a discontinuous curve is formed at the center or at the end of the release film. Attempts have been made to remove the part of the peeling protective film by applying a cut line, and then apply it to the affected area, such as the shoulder or the waist, and then peel off the remaining part of the peeling protective film. Not enough. Furthermore, there is no patch packaging bag that has both means for attaching the patch alone to the shoulder or waist and means for storing the patch in the patch packaging bag itself.

[0007]

A patch such as a cataplasm or a plaster is prepared by applying a drug-containing pressure-sensitive adhesive layer on the surface of a support such as a non-woven fabric, a woven fabric or a synthetic resin film, and further applying a pressure-sensitive adhesive layer thereon. It is obtained by laminating release protection films. The patch is to be adhered to the affected part of a person, and the support film and the pressure-sensitive adhesive layer are required to be flexible and have excellent followability to the adhered portion. On the other hand, when applying the patch to the affected area, generally, the peeling protection film of the adhesive is peeled off, and the patch is applied to the affected area. Since the pressure-sensitive adhesive layers of the patch are stuck to each other before, they cannot be stuck well. Particularly in the case of elderly or young children, this tendency is increased when the patch is applied alone to the shoulder or waist. In addition, if the support is made hard, the patch is slightly improved, but the flexibility of the patch is lost, and the feeling of use at the time of sticking is deteriorated.

Therefore, when the patch is applied alone to an affected area such as a shoulder or a waist, a packaging bag is used as a tool which can be applied well without sticking the adhesive layers of the patch together. An object of the present invention is to find a packaging bag for a patch which has both a means for adhering the patch successfully and a function for storing the patch.

[0009]

SUMMARY OF THE INVENTION The present invention relates to a patch bag for storing a patch, which is provided with a means for facilitating sticking of the patch to a shoulder, a waist, or the like when the patch is to be stored. It is. That is, in the present invention, the innermost layer includes a heat-sealable synthetic resin film, and at least two laminated sheets composed of a base material layer containing a material having a barrier property are laminated with the innermost layers, and the peripheral portion is heat-sealed. A packaging bag for a patch, comprising: either applying a removable adhesive to the outermost layer on either the front surface or the back surface of the packaging bag, or applying a removable double-sided adhesive tape. An adhesive surface is provided on the surface of the packaging bag by the means of (1), and a packaging bag for a patch is provided, wherein a peelable protective liner for protecting the adhesive surface is attached to the adhesive surface. It is.

[0010] The first purpose of the patch packaging bag of the present invention is for storage of the patch. Due to the nature of the patch, the packaging bag does not allow the volatile drug contained in the patch to volatilize. It is preferable to use a bag having a barrier property in order to prevent the influence of the intrusion of external moisture. For this purpose, at least a film of a material having a barrier property is included as a constituent element of the base material layer, and two laminated sheets each having a heat-sealable synthetic resin film laminated as the innermost layer, the innermost layers are overlapped with each other, The packaging bag used in the present invention can be obtained by heat sealing the part and bonding a plastic fastener near the upper part of the packaging bag.

The laminated sheet for producing the patch bag of the present invention preferably contains a film of a barrier material in the base layer. Specifically, the barrier material may be a metal such as aluminum. One or two or more kinds of foils, vapor-deposited films of metal oxides such as aluminum oxide and silicon oxide, and other materials can be used in any combination.

As the base material layer, in addition to the above-mentioned barrier material, paper or a synthetic resin film or sheet can be used as the base material. As the paper substrate, for example, known paper substrates such as thin paper, glassine paper, pure white roll paper, paperboard, kraft paper, and processed paper can be used. In the present invention, the paper substrate is usually used for holding rigidity, waist and the like in a packaging bag, and is also used for holding printed patterns such as characters, figures, symbols and pictures. Is what you do.

In the present invention, the above-mentioned film or sheet may be any of unstretched, uniaxially or biaxially stretched and the like. The thickness is arbitrary, but can be selected from a range of several μm to about 300 μm. Further, in the present invention, the film or sheet may be a film having any property such as extrusion film formation, inflation film formation, and coating film.

The material of the innermost layer of the heat-sealing film of the packaging bag includes low-density polyethylene, medium-density polyethylene,
High density polyethylene, linear low density polyethylene, polypropylene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, ionomer resin, ethylene-
Ethyl acrylate copolymer Ethylene-acrylic acid copolymer, methylpentene polymer, polyolefin-based resin such as polybutene-based resin, polyvinyl chloride-based resin, etc. A film composed of a single substance or a mixture can be used.

The layer structure of the laminate of the present invention will be described below with reference to examples. The layer structure of the laminate is, from the outside to the inside, a paper layer / polyethylene layer / aluminum layer / polyethylene layer, a cellophane layer / paper layer / polyethylene layer / aluminum layer / polyethylene layer, and a polyester layer / polyethylene layer / paper layer. / Polyethylene layer / aluminum layer / polyethylene layer.

[0016] The innermost layer of the two laminated films is superposed on each other, and the periphery thereof is heat-sealed to provide a heat-sealing portion.
If the sheet width is smaller than 5 mm, the airtightness of the bag will deteriorate, and the strength of the seal portion will be weakened when the patch is removed from the storage bag or stored again. This is not preferable because it peels off and deteriorates airtightness. On the other hand, if the width of the seal portion exceeds 15 mm, the storage space for the contents is reduced.

The size of the packaging bag of the present invention has two functions, that is, the function of storing the patch and the function of a tool for applying the patch alone to the shoulder or the waist by itself. The size of the packaging bag for patches of the present invention has a short side of 13 to
It is preferable that the length is 18 cm and the long side is 18 to 23 cm from the viewpoint of exhibiting the two functions described above. It becomes difficult to operate the device by hand, and if it is larger than this, convenience deteriorates.

[0018] A plastic fastener is provided on the upper inner surface of the packaging bag of the present invention. The plastic fastener is for resealing the packaging bag after opening, and is composed of a convex tape having a convex piece and a concave tape having a concave piece, and these two tapes are respectively attached to the upper side of the inner surface of the packaging bag. At the lower part of the heat seal part, the convex and concave pieces of the two tapes are respectively adhered to places suitable for biting. The material of the plastic fastener may be any material that can be heat-sealed with the resin film having heat sealing properties of the innermost surface of the laminate used when manufacturing the packaging bag. Depending on the type of resin film having sealing properties, polyethylene resins such as low-density polyethylene, linear low-density polyethylene, medium-density polyethylene, and high-density polyethylene, polypropylene resins, ionomer resins, ethylene-methacrylic acid copolymer A molded article made of a resin having heat sealing properties such as a coalesced or ethylene-vinyl acetate copolymer can be used. The method for bonding the plastic fastener may be any of a method of bonding by heat sealing and a method of bonding using an adhesive. The widths of the convex side tape and the concave side tape constituting the plastic fastener may be the same, or the widths may be different.
It is preferable to use a tape having a width of 8 mm, and a convex piece and a concave piece having a width of 1 to 2 mm are respectively provided at the center of the convex tape and the concave tape.

As a means for applying the patch alone to the shoulder or the waist, an adhesive surface is provided by applying a double-sided adhesive tape or an adhesive to the outermost layer on one surface of the packaging bag. The double-sided pressure-sensitive adhesive tape used as one of the means will be described. The support of the double-sided adhesive tape is a polyester film,
Polyethylene film, synthetic resin film selected from vinyl chloride film, etc., nonwoven fabric, or a film selected from cotton cloth can be used, but using a polyester film, in terms of compatibility and strength with the adhesive applied to both sides Most preferred, but not particularly limited. The first surface adhesive and the second surface adhesive applied to both surfaces of the double-sided adhesive tape may be any adhesive as long as they are selected from polyacrylic and rubber-based adhesives. It is essential that the second-sided adhesive has a lower adhesive strength than the first-sided adhesive to be adhered to, and the second-sided adhesive is preferably selected from re-peelable adhesives. ~ 1
The adhesive strength is preferably 5.0 N / 20 mm, and when the adhesive strength is less than 2.0 N / 20 mm, the adhesive strength is weak and the patch cannot be held on the adhesive. On the other hand, if the adhesive force exceeds 15.0 N / 20 mm, the adhesive force is so strong that it is difficult to peel the patch from the support of the patch after sticking the patch on the shoulder or waist, which is not preferable. Also, the first
When the adhesive force of the surface adhesive is significantly weaker than the adhesive force of the second surface adhesive, after the patch is applied to the shoulder or the waist, and when the packaging bag is peeled off from the support of the adhesive, both surfaces of the adhesive surface are removed. It is not preferable because the tape may remain on the support. The double-sided adhesive tape may be colorless or colored, or may be transparent, translucent, or opaque. Specific examples of the adhesive tape include double-sided adhesive tapes 769 and 769X for re-peeling manufactured by Teraoka Seisakusho.

As an adhesive applied to the outer surface as another adhesive means provided on the outer surface of the packaging bag of the present invention, the same removable adhesive as the second surface adhesive of the double-sided adhesive tape can be used. The effect of the present invention can be obtained by using.

The range of the adhesive surface provided on the outer surface of the packaging bag of the present invention is preferably provided within a range not exceeding the size of the patch, and may be provided on the entire surface within the range or intermittently. There may be. The size of the patch is 10 × 14
cm is generally widely used. In this case, a double-sided adhesive tape having a width of 2 cm, a length of 12 cm, and a thickness of 0.01 to 0.2 mm is used in this range.
A book or three of them are stuck in parallel to the long side of the packaging bag, or a double-sided sticky tape is applied to the place where a double-stick tape is stuck to provide an adhesive surface. The minimum size of the adhesive surface is preferably at least one half of the long side and the short side of the patch, respectively, from the viewpoint of convenience. If it is less than this, when the patch is applied to the shoulder or the waist, the adhesive surface of the patch is stuck to the patch, which is not preferable because it cannot be applied properly.

The peelable liner for protecting the adhesive surface is selected from a polyester resin film, a synthetic resin film such as a polyethylene film, a metal thin film such as an aluminum foil, or a paper whose surface has been subjected to a release treatment. Other materials can be used as long as they can be easily peeled off from the adhesive surface and can be re-attached after use. It is preferable that the size of this liner is the same as the size of the adhesive surface, or a liner slightly larger than the size of the adhesive surface. If the liner is smaller than the size of the adhesive surface, the adhesive surface will be exposed, which is not preferable.If one side of the liner is larger than the adhesive surface by 1 cm or more, the non-adhesive surface becomes large, and from the viewpoint of handling and appearance. Not preferred.

In addition to the above, a dashed line for opening, or an I-shaped notch or a V-shaped notch may be provided between the plastic fastener of the packaging bag of the present invention and the heat seal portion at the upper end.

EXAMPLES Next, specific examples will be described in detail, but do not particularly limit the scope of the present invention.

Example 1 A heat-sealing layer was made of a polyethylene film, and two sheets of laminated aluminum foil, a polyethylene film, and a polyester film were laminated on one surface in this order.
A patch of 14 cm was stored inside, and the four peripheral portions were heat-sealed to provide a heat-sealed portion of 8 mm width. Further, the lower end of the polyethylene plastic fastener was located 3 cm from the upper end of the upper part, A convex tape and a concave tape each having a width of 13 mm are heat-sealed on the inner surface of the packaging bag to produce a packaging bag. Two double-sided double-sided pressure-sensitive adhesive tapes having a width of 2.0 cm and a length of 12.0 cm (3.5 cm) parallel to the side edges and 3.5 cm from the left edge of the long side of the back side of this packaging bag (Teraoka Manufactured by Seisakusho, double-sided adhesive tape 769 for re-peeling; first-side adhesive: acrylic-based adhesive; second-side re-peeling adhesive: rubber-based adhesive; adhesive strength: 4.90 N / 2
0 mm) is attached to the outer surface of the back surface of the packaging bag at an interval of 4 cm. Further, the second adhesive surface of two double-sided adhesive tapes for single-sided removal (adhesive surface for removable)
A protective release liner of a polyester film having the same width and length was attached to the surface of the above to prepare a patch packaging bag.

Example 2 An adhesive surface having a long side of 12 cm and a short side of 8 cm was provided substantially at the center of the back surface of the same packaging bag as in Example 1, and a rubber adhesive for re-peeling was applied to the entire surface of the adhesive surface. Then, a protective release liner of a polyester film having the same size as that of the protective film was adhered to produce a packaging bag for a patch.

Comparative Example 1 Example 1 was repeated except that a double-sided non-removable double-sided adhesive tape (Teraoka Seisakusho, double-sided adhesive tape 707) was used instead of Example 1 and two single-sided double-sided adhesive tapes. In the same manner as in Example 1, a packaging bag for patches of Comparative Example 1 was produced.

Adhesion Test of Patch When applying the patch to the shoulder, a conventional method, the packaging bag for the patch of the present invention, and the packaging bag of the comparative example were used to apply the patch alone to the shoulder. Tested for convenience.

Conventional method of applying a patch One patch was taken out of the packaging bag, the protective release liner was removed, the patch was held with the left hand, and the patch was stuck on the right shoulder. Partly stuck, it took considerable time to stick properly.

Test Example One patch was taken out from each of the patch packaging bags of Example 1 and Comparative Example 1. Next, insert your left hand into the opening of the patch packaging bag, and remove the protective liner on the adhesive surface on the back of the packaging bag. Subsequently, the support part of the patch was attached to the adhesive surface, the release liner of the patch was removed, and the adhesive surface of the patch was applied to the right shoulder of the affected area, and further,
The patch was stuck to the right shoulder by peeling the packaging bag from the patch support. As a result, when the packaging bag of Example 1 was used, it was possible to apply the patch to the right shoulder very smoothly. On the other hand, when the packaging bag of Comparative Example 1 was used, since the pressure-sensitive adhesive surface was a non-removable pressure-sensitive adhesive, it was strongly adhered to the support of the patch, and was difficult to re-peel. When peeled, the fibers of the nonwoven fabric of the support adhered to the adhesive on the adhesive surface, and the adhesive force on the adhesive surface was lost. (Cannot be reused.)

[0031]

As is apparent from the above description, by providing a removable adhesive surface on one surface of the patch packaging bag, a hand is inserted through the opening of the packaging bag, and the adhesive patch is placed on the adhesive surface. After pasting the support part and pasting the patch to the affected area, the patch can be pasted on the adhesive side of the packaging bag by peeling the patch support again, such as the shoulder or waist. Even when sticking to a place that was said to be difficult, by using the patch packaging bag of the present invention, the adhesive layer of the patch does not stick when sticking, making it extremely easy The adhesive surface can be used a plurality of times after attaching the protective liner again after one use. Further, the packaging bag is provided with a plastic fastener in the opening and is excellent in airtightness, so that the patch is excellent in storage of the patch.
