Description

  The present invention relates to a packaging bag for packaging an adhesive tape having an adhesive layer on a support.

  Conventionally, adhesive tapes having various forms are known, and are used for labels, medical, cosmetic, decorative, masking, electronic industry, and other various uses. The adhesive tape used for medical purposes is usually applied to the skin, mucous membrane, etc. in the form of a patch such as a poultice, plaster, bandage, surgical tape or the like.

  Such a pressure-sensitive adhesive tape is usually composed of a pressure-sensitive adhesive tape having a support and a pressure-sensitive adhesive layer provided on one surface of the support, and a release sheet attached to the pressure-sensitive adhesive layer in a peelable manner. . After the adhesive tape is manufactured, it may be cut into an appropriate size and may be distributed and sold in a state of being individually put in a packaging bag for hygienic and physical protection. In this case, at the time of use, the packaging bag is broken, the adhesive tape is taken out, the release sheet is peeled off to expose the adhesive layer, and it is applied to the application site.

  A common problem in use is the difficulty of peeling the release sheet. Since the release sheet is generally thin and flexible, it is difficult to handle and may take time to peel off. In order to improve this point, various release sheets and pressure-sensitive adhesive tapes that pursue ease of peeling of the release sheet and ease of sticking of the pressure-sensitive adhesive tape have been developed (for example, Patent Documents 1 to 4).

JP 2007-75602 A JP 2007-75601 A Japanese Patent No. 3689807 Japanese Utility Model Publication No. 50-133797

  These release sheets or adhesive tapes have a structure that pursues convenience from the viewpoint of ease of sticking the adhesive tape. Although it is certainly convenient, there is no change in that the pressure-sensitive adhesive tape has a mode in which the release sheet and the packaging bag are provided, and the release sheet and the packaging bag are generated as garbage after use.

  The objective of this invention is providing the adhesive tape which can show | play the effect of resource saving, pursuing the ease of sticking of an adhesive tape.

  To achieve the above object, the present invention provides an adhesive tape packaging bag containing an adhesive tape having a support and an adhesive layer provided on one surface of the support, the adhesive layer In the pressure-sensitive adhesive tape packaging bag composed of a release sheet that is releasably attached to the adhesive sheet, the release sheet is composed of a first portion and a second portion facing the first portion, and the adhesive layer faces outward. In this way, the adhesive tape is folded into the first part and the second part, the folded adhesive tape is sealed between the first part and the second part of the release sheet, and the first part and the second part of the adhesive tape are sealed. Temporary fixing means is provided between the first part and the adhesive force suppressing means is partially provided between the first part of the release sheet and the first part of the adhesive sheet. The second part of the release sheet and the second part of the adhesive sheet It is characterized in that is provided partially other adhesion suppressing means to.

  By setting it as such a structure, it becomes possible to abbreviate | omit the packaging bag which existed conventionally. Further, for example, when the first part of the release sheet is peeled from the vicinity of the adhesive force suppressing means between the first part of the release sheet and the first part of the pressure-sensitive adhesive sheet, the pressure-sensitive adhesive layer agent of the first part of the pressure-sensitive adhesive sheet is exposed. . Further, for example, when the second part of the release sheet is peeled from the vicinity of the adhesion suppressing means between the second part of the release sheet and the second part of the pressure-sensitive adhesive sheet, the adhesive layer agent of the second part of the pressure-sensitive adhesive sheet is exposed. . That is, if it is known from which part of the release sheet the adhesive sheet is exposed, the exposed side of the adhesive layer agent can be known, and the pasting operation after the exposure becomes easy. Furthermore, since the adhesive tape is sealed inside the release sheet, the inside is blocked from the outside, the adhesive tape is more hygienic and physically protected, and the components of the adhesive layer of the adhesive tape do not leak to the outside.

  Moreover, it is preferable to provide the non-adhesion part as a pick part for opening two places between the 1st part and 2nd part of a peeling sheet. In this case, the two non-adhesive portions are the vicinity of the adhesive force suppressing means between the first portion of the release sheet and the first portion of the adhesive sheet, and the second portion of the release sheet and the second portion of the adhesive sheet, respectively. It is good to arrange | position in the vicinity of the other adhesive force suppression means between. Further, when a mark that can be recognized by a tactile sensation such as a notch is provided on the non-adhered portion, even the visually impaired can easily grasp the direction in which the pressure-sensitive adhesive layer of the pressure-sensitive adhesive tape is exposed.

  As long as the release sheet can protect the adhesive layer of the adhesive tape until use, the material and configuration are not particularly limited, but a cellophane film, plastic film, aluminum foil from the outer layer, and then a plastic film laminated on the inner layer The structure is preferable, and the adhesion suppressing means is preferably a silicon-treated surface provided on a part of the release sheet that adheres to the adhesive layer of the first part of the adhesive tape. Among various adhesive force suppression means, there is an advantage that silicon treatment can be performed relatively easily and inexpensively. In addition, as the adhesive force suppressing means, the part may be embossed and / or sanded.

  The temporary fixing means between the first part and the second part of the pressure-sensitive adhesive tape is preferably a pressure-sensitive adhesive, that is, one having adhesiveness to the supports.

  The pressure-sensitive adhesive tape packaging bag configured as described above is adhered to the part where the exposed portion of the pressure-sensitive adhesive layer of the pressure-sensitive adhesive tape appears at the same time that the release sheet is opened, and then the direction away from the longitudinal direction of the release sheet and the pressure-sensitive adhesive tape. The whole surface of the pressure-sensitive adhesive tape can be applied to the application site by pulling it along the application site.

  According to the pressure-sensitive adhesive tape packaging bag of the present invention, the pressure-sensitive adhesive tape can be applied to other pressure-sensitive adhesive tapes as long as the pressure-sensitive adhesive tape has a release sheet and is individually packaged. An easy adhesive tape packaging bag is provided. That is, the pressure-sensitive adhesive tape packaging bag of the present invention can omit the packaging bags that exist individually, and even when the pressure-sensitive adhesive tape is stored, the inside of the pressure-sensitive adhesive tape packaging bag is sealed by sealing the release sheet. Since it is shielded from the outside world, the adhesive tape is hygienically and physically protected.

  In addition, when using the adhesive tape, even if it is peeled off from either the first part or the second part of the release sheet, the adhesive layer of the adhesive tape is exposed on the peeling side, and the exposed side of the adhesive layer is The adhesive layer is not attached to the hand without knowing, and the application to the application site becomes easy. Moreover, after the half of the release sheet is peeled off, the adhesive tape is supported or reinforced on the remaining part of the release sheet, so that the adhesives are not bonded and the adhesive tape cannot be used. This also facilitates sticking. In the case of adhesives that can be applied to the human body, such as plaster agents, poultices and adhesive bandages, surgical tapes, and paste-on type warmers, even if the application site is on the back, etc. Can be easily affixed with one hand.

  Furthermore, since the adhesive tape packaging bag of the present invention is commercialized in units of one sheet, it is excellent in portability.

(A) And (b) is a schematic explanatory drawing which shows the modification of embodiment of FIG.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  (A)-(c) of FIG. 1 is a perspective view showing the manufacturing process of the adhesive tape packaging bag 10 by this invention. The pressure-sensitive adhesive tape packaging bag 10 includes a pressure-sensitive adhesive tape 14 having a pressure-sensitive adhesive layer 12 on one surface, and a release sheet 16 that covers the whole pressure-sensitive adhesive tape 14. Both the adhesive tape 14 and the release sheet 16 are preferably rectangular.

  FIG. 2 shows a cross-sectional view of a state in which the release sheet 16 is attached to the adhesive tape 14. The pressure-sensitive adhesive tape 14 includes a support 18 and a pressure-sensitive adhesive layer 12 laminated on one surface thereof, and a release sheet 16 is detachably attached thereto.

  The pressure-sensitive adhesive tape packaging bag 10 of the present invention is used for labels, medical use, cosmetic use, decoration use, masking use, electronic industry use, and other various uses. In particular, adhesive tape packaging bags used for medical purposes, cosmetics, etc. are patches, plasters, adhesive bandages, surgical tapes, cosmetic packs, paste type warmers, etc. It can be used as a packaging bag.

  Although the constituent material of the support 18 is not particularly limited as long as it can support the pressure-sensitive adhesive layer 12, a film made of woven fabric, non-woven fabric, plastic or the like, metal foil or the like is usually used. Further, the support may be a single layer structure or a laminated structure, for example, may be a structure in which a plurality of woven fabrics or nonwoven fabrics made of different materials are laminated, and a plastic film, a metal foil, etc. and a woven fabric or nonwoven fabric. A laminated structure may also be used.

  In addition, the woven fabric or the nonwoven fabric used in the present invention is not particularly limited, and may be any fabric material that has been processed into a cloth shape and can be used for the support 18 of the pressure-sensitive adhesive tape 14. Also included are knitted fabrics that are processed into a cloth shape by gathering the stitches by round knitting, warp knitting, weft knitting, or the like.

  Preferable examples of the woven or non-woven fabric include a woven or non-woven fabric made of at least one resin fiber selected from the group consisting of polyester-based resins, polyethylene-based resins, and polypropylene-based resins. A woven fabric made of polyester-based polyethylene terephthalate that has little interaction with components is preferred.

  Examples of the plastic film include polyesters such as polyethylene terephthalate, polyamides such as nylon, polyolefins such as polyethylene and polypropylene, polyvinyl chloride, plasticized polyvinyl chloride, plasticized vinyl acetate-vinyl chloride copolymer, polyvinylidene chloride, Examples thereof include ethylene-vinyl acetate copolymer, cellulose acetate, ethyl cellulose, ethylene-ethyl acrylate copolymer, polytetrafluoroethylene, polyurethane, and ionomer resin. In addition, when the adhesive tape 144 of the present invention is used as a medical or cosmetic patch, it is preferable to use a material having sufficient stretchability or non-stretchability as the patch for the support 18. Polyethylene terephthalate knitted fabric (knitted fabric) is preferred.

The knitted fabric as the support 18 preferably has a basis weight (mass per unit) of 50 to 500 g / m ² . The support 18 preferably has a longitudinal (major axis) modulus of 2 to 12 N / 5 cm and a transverse (minor axis direction) modulus of 2 to 12 N / 5 cm when measured according to the method of JIS L1018. . In addition, the vertical direction here refers to the flow direction in the process of manufacturing a knitted fabric, and the horizontal direction refers to the direction orthogonal to the vertical direction, that is, the width direction. When the longitudinal or lateral direction has a modulus lower than 2 N / 5 cm, it tends to be difficult to apply the adhesive while extending wrinkles on the applied part, and the longitudinal or horizontal direction has a modulus higher than 12 N / 5 cm. In the case, on the contrary, the adhesive tape tends to be stretched too much at the time of sticking and tends to cause wrinkles. The modulus is a value at room temperature (25 ° C.).

  By using said support body 18, it becomes easy to fold in two in the adhesive tape packaging bag 10 mentioned later, and does not become bulky. In addition, when pasting, the portion that has been folded in half is less likely to have a so-called “garbage” and can be neatly pasted.

  The pressure-sensitive adhesive component that is a constituent material of the pressure-sensitive adhesive layer 12 is not particularly limited as long as it has adhesiveness and can be attached to a sticking site. An adhesive component or the like is preferably used, and a rubber-based adhesive component is particularly preferably used from the viewpoint of adhesive physical properties.

  As a specific rubber-based adhesive component, either natural rubber or synthetic rubber can be used. Examples of the synthetic rubber include styrene-based block copolymers and polyisobutylene. Further, styrenic block copolymers include styrene-butylene-styrene block copolymer (SBS), styrene-isoprene-styrene block copolymer (SIS), styrene-ethylene / butylene-styrene block copolymer (SEBS), styrene-ethylene / propylene- Styrene block copolymer (SEPS) is mentioned.

  Specific examples of the styrenic block copolymer include Kraton D-1112, D-1111, D-1107 (trade name, manufactured by Kraton Polymer Co., Ltd.), JSR5000 or JSR5002 (trade name, manufactured by Nippon Synthetic Rubber Co., Ltd.), Linear triblock copolymers such as Quintac 3530, 3421 or 3570C (trade name, manufactured by ZEON CORPORATION), Clayton D-KX401CS or D-1107CU (trade name, manufactured by Kraton Polymer Co., Ltd.), and Clayton D-1124 (Brand name, manufactured by Kraton Polymer Co., Ltd.), Sorprene 418 (Brand name, manufactured by Philippe Petroleum Co., Ltd.) and the like.

  As the polyisobutylene, for example, polymers to low molecular weight compounds are used. Manufactured by Co., Ltd.), Vistanex LM-MS, LM-MH, LM-H, MM L-80, MM L-100, MM L-120, MM L-140 (trade name, manufactured by Exxon Chemical Co., Ltd.) Etc.

  In addition, as the acrylic polymer, as a monomer unit, for example, (meth) acryl represented by 2-ethylhexyl acrylate, methyl acrylate, butyl acrylate, hydroxyethyl acrylate, 2-ethylhexyl methacrylate, and the like A polymer or copolymer containing at least one acid ester is used. For example, acrylic acid / octyl acrylate ester copolymer, acrylic acid-2-ethylhexyl / N-vinyl-2-pyrrolidone / dimethacrylic acid 1,6-hexane glycol copolymer, 2-ethylhexyl acrylate / vinyl acetate copolymer, 2-ethylhexyl acrylate / vinyl acetate / acrylic acid copolymer, 2-ethylhexyl acrylate / methacrylic acid-2 -Ethylhexyl / dodecyl methacrylate copolymer, Methyl acrylate / acrylic acid-2-ethylhexyl copolymer resin emulsion, pressure sensitive adhesive such as acrylic polymer contained in acrylic resin alkanolamine liquid, Duro-Tak acrylic pressure sensitive adhesive series (manufactured by National Starch and Chemical Co., Ltd.), GELVA acrylic The pressure-sensitive adhesive series (manufactured by Monsanto), SK Dyne Matriderm (Soken Chemical), Eudragit series (Higuchi Shokai), etc. can be used.

  The rubber-based, acrylic-based, and silicon-based adhesive bases can be used alone or in combination of two or more.

  Further, when the pressure-sensitive adhesive tape 14 of the present invention is used as a medical poultice, plaster, or cosmetic pack, a water-soluble polymer can also be used as the pressure-sensitive adhesive layer. As gelatin, agar, alginic acid, mannan, carboxymethylcellulose or a salt thereof, hydroxypropylcellulose, polyvinyl alcohol, polyacrylic acid or a salt thereof, or at least one of them is crosslinked with an organic or inorganic crosslinking agent Those are preferably used.

  In addition to the above adhesive base, the pressure-sensitive adhesive layer 12 is appropriately provided with a tackifier, a softener, a solubilizer, water, a thickener, a wetting agent, a filler, a cross-linking agent, a polymerization agent, a solubilizing agent, and absorption promotion. Agents, stabilizers, antioxidants, emulsifiers, surfactants, pH adjusters, drugs, UV absorbers and the like are added.

  The drug when the adhesive tape 14 of the present invention is used as a medical or cosmetic patch is not particularly limited as long as it is percutaneously absorbed into the body and exerts a pharmacological effect. , Anti-inflammatory agents, analgesics, antihistamines, local anesthetics, blood circulation promoters, anesthetics, tranquilizers, antihypertensive agents, antibacterial agents, vasodilators and the like.

  The release sheet 16 of the present invention can be used as long as it is normally used as a packaging bag for the adhesive tape 14. Moreover, the release sheet 16 may be either a single layer or a laminated layer, and the material constituting the release sheet 16 is not particularly limited as long as the effect of the present invention is exhibited. For example, paper, non-woven fabric, aluminum, cellophane, nylon, high density or low density polyethylene, polyethylene terephthalate, polypropylene, polyvinyl chloride, polyamide, polyvinylidene chloride, polyvinyl alcohol, polyvinyl acetate copolymer, polycarbonate, polystyrene, ethylene It can be appropriately selected from vinyl alcohol copolymers and the like.

  Furthermore, what applied printing ink or the adhesive agent etc. to these, or what provided the thin film by methods, such as vapor deposition or sputtering, may be used. As the thin film, in addition to a metal such as aluminum, a thin film having high gas barrier properties and transparency such as silicon oxide, magnesium oxide, and aluminum oxide is suitable. Among these, a film containing aluminum is preferable, a film in which polyethylene, aluminum, and polyethylene are sequentially stacked is more preferable, and a film in which cellophane is stacked on the outermost layer is preferably used.

  These release sheets 16 are preferably flexible because they are bent when the adhesive tape 14 is sealed. Accordingly, the thickness of the release sheet 16 is not particularly limited as long as it can be bent, but is preferably in the range of 10 to 500 μm, and more preferably in the range of 15 to 300 μm.

  The pressure-sensitive adhesive tape 14 shown in FIG. 1 (a) is placed on the part of the release sheet 16 indicated by the two-dot chain line, and both are detachably attached to the state shown in FIG. 1 (b). . At this time, the center line of the adhesive tape 14 parallel to the short direction and the center line of the release sheet 16 parallel to the short direction substantially coincide.

  Here, the hatched portions 20 and 22 in FIG. 1A are portions (hereinafter referred to as “adhesive force”) provided with adhesive force suppressing means for weakening the adhesive force between the adhesive tape 14, the adhesive layer 12, and the release sheet 16. Referred to as a “suppressed part”. Therefore, the adhesive tape 14 can be peeled off from the release sheet 16 more easily than the other parts by the adhesive force suppressing portions 20 and 22. The adhesion suppressing portions 20 and 22 are considered to have been subjected to a peeling treatment. As the peeling treatment, in addition to a method using a release agent, a method for facilitating physical peeling such as embossing and sanding. Is also included. As the release agent, any of a silicon release agent, an alkyl pendant release agent, a condensed wax release agent, and the like can be used, and among these, so-called silicon treatment using a silicon release agent is preferable. This is because silicon processing has an advantage that it can be performed relatively easily and inexpensively.

  Next, the release sheet 16 is bent together with the adhesive tape 14 along the center line from the state shown in FIG. 1B to form the first portion 24 and the second portion 26 having the same shape. The adhesive tape 14 is sealed inside the folded release sheet 16 in a folded state, and the adhesive tape packaging bag 10 of the present invention is completed ((c) in FIG. 1).

  The adhesive tape 14 is bent into a first portion 28 and a second portion 30 having the same shape, and these portions 28 and 30 are overlapped with each other, but are not opened together with the release sheet 16 when the release sheet 16 is opened. As described above, a temporary fixing means 32 is provided between the portions 28 and 30. The temporary fixing means 32 is not particularly limited. For example, in addition to magnetic force, electrostatic force, or physical force, for example, magic tape, double-sided tape, adhesive, adhesive, pseudo-adhesion, release sheet 16 Depending on the material and properties of the support 18, welding, thermal bonding, strong pressing, embossing, hot melt adhesive, or the like can be used. In addition, when the support 18 of the adhesive tape 14 is formed of, for example, a woven fabric, temporary fixing by thermal bonding can be performed by infiltrating the thermoplastic material into the woven fabric of the support 18. As described above, various temporary fixing means can be used, and among them, a means using a pseudo adhesive or a hot melt adhesive between the overlapped end portions is effective. Pseudo-adhesion refers to a patent map classified by technical field available from the JPO homepage, General 21 “Adhesion”, page 336 (www.jpo.go.jp/shiryou/s_sonota/map/ippan21/4/4-3 -1. htm), it does not have adhesive properties under normal conditions, but refers to materials that are joined under special pressure conditions, etc., and is a pseudo-adhesive produced by adding an additive to an adhesive. An agent is used.

  As the temporary fixing means, the adhesive force between the first portion 28 and the second portion 30 of the support 18 of the adhesive tape 14 (adhesive force of the temporary fixing means 342) is the adhesive force suppressing portion 20 of the release sheet 16. What is necessary is just to become higher than the adhesive force (adhesive force) of the adhesive layer 12 of the adhesive tape 14 to 22.

  As a method of sealing the adhesive tape 14 in the release sheet 16 folded in half, a portion surrounding the adhesive tape 14 in the part where the first portion 24 and the second portion 26 of the release sheet 16 are overlapped is heat-sealed. A method of sealing using an adhesive or an adhesive is preferable. When the release sheet 16 is sealed, the inside is shut off from the outside, so that the adhesive tape 14 is more hygienic and physically protected, and the components contained in the adhesive layer 12 of the adhesive tape 14 do not leak to the outside. There is an advantage that it does not volatilize. By setting it as such a structure, since the peeling sheet 16 functions also as a packaging bag, it becomes possible to omit the individual packaging bag which existed conventionally.

  Further, in order to facilitate the opening of the adhesive tape packaging bag 10, it is also effective to use a so-called easy peel technique as means for sealing the first portion 24 and the second portion 26 of the release sheet 16. “Easy peel” means easy peelability as described in the above-mentioned patent map for each technical field available from the JPO homepage, general page 21 335 “Adhesion”. A thing that has been sealed and made easy to wave at dawn. Specifically, the easy peel is a cohesive peeling type in which the adhesive layer itself between the first portion 24 and the second portion 26 of the release sheet 16 is broken and peeled, or the adhesive layer and the first portion 24. Alternatively, the adhesive strength of the second part 26 is lowered, and the first part 24 or the second part 26 is peeled off from the adhesive layer at the time of opening. Further, interfacial peeling using an easily adhesive resin such as EVA. There are various types, such as types, and is not particularly limited. However, when a sheet material having a polyethylene layer disposed on the surface is used as the release sheet 16, as an adhesive layer for easy peel, for example, It is preferable to use a two-layer structure composed of a resin layer mainly composed of high-density polyethylene and an easy-peeling resin layer in which a resin causing cohesive failure is added to low-density polyethylene.

  In addition, in order to avoid that the corner | angular part of the completed adhesive tape packaging bag 10 is sharp, the peeling sheet 16 is a shape where a part of the corner part of the completed adhesive tape packaging bag 10, preferably all four corners were rounded off. Thus, it is effective to have a substantially rectangular shape. FIG. 1C shows a state where two corners are rounded.

  Further, all or a part of the edge of the release sheet 16 is formed into a wave shape, a pulse shape, or a strip shape so that, for example, the edge of the release sheet 16 is not damaged by the edge of the release sheet 16 or its periphery. Alternatively, it is possible to use means such as preventing the outermost end of the edge from adhering (see (a) to (d) of FIG. 3).

  Further, as shown in FIGS. 1C and 4A, the end portions of the first portion 24 and the second portion 26 of the release sheet 16 are not bonded, and the non-bonded portion 34 is picked. It has become so. As can be understood from FIG. 1B, the non-adhesive portion 34 has two locations on the first portion 24 of the upper release sheet 16 and two locations on the second portion 26 of the lower release sheet 16. However, for the first portion 24, a non-adhesive portion 34 a close to the adhesive force suppressing portion 20, and for the second portion 26, a non-adhesive portion 34 b close to the adhesive force suppressing portion 22, such as a notch or emboss. It is preferable to attach a mark 36 that can be recognized by tactile sensation. As will be described later, this mark 36 is useful for making it possible for a visually handicapped person to recognize which side the upper side should be peeled off. In addition to the marks 36 that can be recognized by tactile sense, it is preferable to attach pictorial symbols and the like for use instructions to the non-contact portions 34a and 34b. Furthermore, although not shown, the non-adhesive portions 34a and 34b can be configured to protrude from the opposing portions so that the portion to be picked can be easily recognized. In this case, since a step is formed, there is an effect that it becomes easier to pick.

  Next, with reference to FIGS. 4-7, the effect | action and effect of the adhesive tape packaging bag 10 about this embodiment are demonstrated.

  (A) of FIG. 4 has shown the perspective view of the adhesive tape packaging bag 10 about this embodiment. Compared to conventional adhesive tape, it does not have a separate packaging bag from the release sheet, thus saving resources, and the adhesive tape packaging bag 10 of the present invention is commercialized in units of one sheet. It can be seen from this figure that it is convenient.

  First, the user picks the non-contact portion 34 a of the first portion 24 of the release sheet 16. At this time, the visually impaired can also recognize from the mark 36 that the first portion 24 of the release sheet 16 is facing upward, and that peeling may be started from the portion 34a where the mark 36 is present. it can. Next, the sealed release sheet 16 starts to be opened from the non-contact portion 34a (see FIG. 4B). Since the second portion 26 located immediately below the adhesive force suppressing portion 20 of the first portion 24 in the release sheet 16 is not provided with an adhesive force suppressing means, the adhesive tape 14 is attached to the second portion 26 from the first portion. In addition, since the first portion 28 and the second portion 30 of the adhesive tape 14 are temporarily fixed by the adhesive 32, when the release sheet 16 is opened with the non-contact portion 34a, the release portion 16 is peeled off. The end of the first portion 24 of the sheet 16 is peeled off from the first portion 28 of the adhesive tape 14. During this time, the pressure-sensitive adhesive tape 14 is maintained in a folded state on the second portion 26 of the release sheet 16, and finally, as shown in FIG. 4C, the plane before the release sheet 16 is bent. When the adhesive tape 14 is fully opened until it returns to the shape, the first portion 28 is completely peeled off from the release sheet 16, and the adhesive layer 12 of the first portion 28 is exposed upward.

  On the other hand, when the adhesive tape packaging bag 10 is turned upside down from the state of FIG. 4A, the adhesive tape packaging bag 10 is rotationally symmetric about the one-dot chain line in FIG. Even if the non-adhesive part 34b in the two parts 26 is only at the position 34a shown in FIG. 4A, and peeling is started from the non-contact part 34b, as in the case of starting from the non-contact part 34a, The pressure-sensitive adhesive layer 12 of the second portion 30 of the pressure-sensitive adhesive tape 14 is exposed upward.

  Thus, according to the present invention, regardless of the orientation of the first portion 24 and the second portion 26 of the release sheet 16, the portion of the adhesive tape 14 on the same side as the portion where the release of the release sheet 16 is started Since it will be exposed, the direction of exposure of the pressure-sensitive adhesive layer 12 is known in advance, and the subsequent pasting operation becomes easy.

  FIGS. 5 to 7 show the case where the pressure-sensitive adhesive tape 14 according to the present embodiment is used as a patch for medical use or cosmetic use, that is, the pressure-sensitive adhesive layer 12 of the first portion 28 of the pressure-sensitive adhesive tape 14 is exposed. A method of applying the tape packaging bag 10 from below and applying it to the application site will be described. In addition, when using for uses other than this, it can affix by the same method. First, the adhesive tape packaging bag is held in one hand and applied to an application site or the vicinity of the application site as shown in FIG. Next, as shown in FIG. 6, the release sheet 16 is pulled along the skin in the longitudinal direction and away from the adhesive tape 14 while holding the first portion 24 of the release sheet 16. As the release sheet 16 is pulled, the first portion 28 of the pressure-sensitive adhesive tape 14 is peeled off from the release sheet 16 and simultaneously attached to the application site. In particular, since the release sheet 16 is attached while being pulled, it can be attached without wrinkling the adhesive tape 14. FIG. 7 shows a state where the entire adhesive tape 14 has been applied to the application site.

  The pressure-sensitive adhesive tape 14 according to the present embodiment can hold the thumb of the hand carrying the pressure-sensitive adhesive tape 14 on the first portion 24 of the release sheet 16 peeled off from the pressure-sensitive adhesive layer 12, so that it can be held firmly in the hand. it can. Therefore, there is little risk of dropping when the adhesive tape 14 is applied to the application site, and there is less concern that the adhesive tape 14 will shake or hang down in an unintended direction due to gravity. Aim can be set and pasted. Even if the application site is a back or the like that is difficult to apply by one person, it can be easily applied with one hand.

  In addition, in the above-mentioned use operation | movement, there is little possibility that the adhesive layer 12 contacts skin other than a sticking site | part. After the first portion 24 of the release sheet 16 is peeled off, the adhesive tape 14 is removed from the release sheet 16 after the first portion 24 of the release sheet 16 is removed. Since the second portion 26 is supported or reinforced, the adhesive does not adhere to each other and the patch cannot be used.

  The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments.

  For example, in the above-described embodiment, the first portion 24 and the second portion 26 of the release sheet 16 are configured so as not to be separated. However, a weak line (for example, perforation, heat, or the like is applied between the two portions to facilitate tearing). When the release sheet 16 is pulled away from the first portion of the adhesive tape 14, the first portion 24 and the second portion 28 of the release sheet 16 may be separated. This is because, when there are some obstacles around the site to be applied, it may be easier to apply if the release sheet is also small.

  Moreover, in the said embodiment, suppose that the edge part which the 1st part 24 and the 2nd part 26 of the peeling sheet 16 overlapped is heat-sealed, and although it does not mention a bending part in particular, as shown in FIG. Moreover, you may perform the process similar to another edge part also about the bending part 40. FIG. In this case, since the same seal part is formed in all four sides of the adhesive tape packaging bag 10, it will be excellent in aesthetics.

  Furthermore, in the said embodiment, although the peeling sheet 16 was bent and the 1st part 24 and the 2nd part 26 were made, as shown in FIG.9 and FIG.10, the 1st part 124 and 2nd of the peeling sheet 16 are shown. The portions 126 may be composed of independent sheets. In this case, if the periphery of the release sheet 16 is heat-sealed, the structure shown in FIG. 8 can be substantially the same. However, in the embodiment shown in FIGS. The restraining portion 120 and the adhesive force restraining portion 122 on the second portion 126 side are extended along the long side of the release sheet 16, and the non-adhesive portion that becomes the picking portion is also lengthened accordingly, so that opening can be performed more easily. I am doing so. In this case, it is preferable to provide a plurality of temporary fixing means 32 as shown in FIG.

  Further, as shown in FIG. 11, the adhesive tape 14 and the first portion 24 of the release sheet 16 are aligned with the first portion 24 of the release sheet 16 so that the fold line 50 of the release sheet 16 and the fold line 52 of the adhesive tape 14 are opposite to each other. It may be arranged between the two portions 26. Furthermore, it is conceivable that the fold line 50 and the fold line 52 are not parallel but form 90 degrees or other angles.

  Further, when the overlapping portion of the first portion 24 and the second portion 26 of the release sheet 16 is sealed by a heat seal method, for example, as shown in FIG. In addition, it is preferable that a part of the heat seal portion 60 has a chevron shape or a triangular sawtooth shape. In the heat seal portion 60 having such a shape, when the first portion 24 and the second portion 26 are pulled away from each other by gripping the non-adhesive portion 65, the tensile force is sawtooth-shaped heat seal portion 60. Therefore, the heat seal portion 60 starts to break from the top. For example, when opening from the upper right end in FIG. 12, the force concentrates on the top of the mountain indicated by reference numeral 68. In particular, in the shape shown in FIG. 11, since the peak of the mountain is a point, even if the tensile force is small, the force is concentrated on one point, so that the breakage starts easily. Once the rupture starts in the heat seal part 60, the rupture propagates to other parts starting from this rupture start point without applying a larger tensile force, the entire heat seal part 60 breaks, and the adhesive tape The packaging bag 10 is in the state shown in FIG.

  In addition, the height H and the pitch P of the crest-shaped heat seal portion 60 can be determined as appropriate. However, when P is large with respect to H, the angle at the top of the mountain increases and the effect of force concentration is impaired. On the other hand, if P is small, the tensile force applied to the portion 65 is dispersed at the tops of two or more peaks, and a large force is required for opening. On the other hand, when H is small, it becomes close to a linear heat seal portion, and in this case as well, a large force is required for opening. Considering such points, it is preferable that H is about 10 mm and P is about 10 to 20 mm.

  FIG. 13A is a modification of the heat seal portion 60 of FIG. 12, and has an edge that is the inner side of the sawtooth heat seal portion that is linear. Thus, by making one edge straight, the touch when the heat seal portion 60 is broken becomes smooth.

  In addition, since the heat seal portion 60 can be easily broken by concentrating the force at one point, only one convex point 70 protruding toward the knob portion 65 is heated as shown in FIG. It is good also as forming in the seal | sticker part 60. FIG. In the configuration of FIG. 13B, the portion other than the convex point 70 of the heat seal portion 60 has a gentle mountain shape. This is because breakage from the convex point 70 is easy to propagate to other portions. It is to do.

  Further, the means for joining the first portion 24 and the second portion 26 of the release sheet 16 is not limited to heat sealing, and a method using an adhesive or the like is also conceivable. By forming at least one convex point protruding in the shape, it is possible to obtain the same easy-opening property as the heat seal part 60 shown in FIGS. 12 and 13.

  As an adhesive, 20 parts of styrene-isoprene-styrene block copolymer, 20 parts of polyisobutylene, 45 parts of liquid paraffin, and 15 parts of hydrogenated rosin glycerin ester were mixed and spread on a woven cloth of polyethylene terephthalate to obtain an adhesive tape. . Further, a laminated film (thickness: 80 μm) of polyethylene terephthalate, aluminum, and polyethylene was cut so as to have an area larger than that of the adhesive tape, and a silicon treatment was applied to a part of one surface as an adhesion suppressing means. The silicon-treated portions are the positions shown in the hatched portions in FIG. 1, that is, a pair of opposite corner portions. Next, the pressure-sensitive adhesive tape is placed on the release sheet so that the pair of opposite corners of the pressure-sensitive adhesive tape are positioned on the silicon-treated portion. Then, a pressure-sensitive adhesive was applied as a temporary fixing means in the vicinity of one short edge of the pressure-sensitive adhesive tape support, that is, the surface of the polyethylene terephthalate woven fabric without the pressure-sensitive adhesive. Finally, the release sheet was folded so that the adhesive tape was included, and the edge was heat sealed. Thereby, the adhesive tape packaging bag of the form shown to (c) of FIG. 1 and (a) of FIG. 4 was obtained.

  When such an adhesive tape packaging bag was opened, as shown in FIG. 4C, the folded adhesive tape was left on the release sheet with its adhesive layer exposed upward. Moreover, although it opened also from the other side, the adhesive tape was similarly left on the peeling sheet in the state which exposed the adhesive layer upwards. Thereafter, application to the skin was performed according to the procedure shown in FIGS. 5 to 7, but the adhesive tape was easily and smoothly applied to the skin without wrinkles.

  In addition, according to the point of the said Example, the formation conditions of a heat sheet part were changed, and several adhesive tape packaging bags of the shape shown in FIG. 12 were produced, and a heat seal part (part 60 of FIG. 12) of an opening force test was carried out. The force required for opening was measured, and the performance of each packaging bag was evaluated by a sensory test.

  In the opening force test, a tensile tester Autograph AGS-1 kgNG (manufactured by Shimadzu Corporation) was used. When the opening ends of the packaging bags (in FIG. 12, the upper portions of the first portion 24 and the gripping portion 65 of the second portion 26) are set on the holding jigs and pulled in opposite directions at an opening speed of 300 mm / min (so-called The force per 25 mm width required for opening the heat seal portion (portion 60 in FIG. 12) at the time of T-shaped opening was measured. The measurement results are as shown in the following table.

  From the above table, when the force required to open the packaging bag is in the range of 0.5 to 10 N / 25 mm, the sensory test result is “good”, especially when the force is in the range of 1 to 5 N / 25 mm. It is understood that is “particularly good”. From this result, it is desirable to determine the formation conditions of the heat seal part so that the force required to open the packaging bag is in the range of 0.5 to 10 N / 25 mm, more preferably in the range of 1 to 5 N / 25 mm. This makes it possible to obtain a pressure-sensitive adhesive tape packaging bag that is easy to open even for elderly people and patients who are weak, and has good sealing properties.
