Description

Adhesive tape packaging bag

Technical Field

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

Background

Conventionally, adhesive tapes having various shapes have been known and used for labels, medical applications, cosmetic applications, decorative applications, masking applications, electronic industry applications, and other various applications. The pressure-sensitive adhesive tape used for medical use is generally applied to the skin, mucous membrane, or the like in the form of a pressure-sensitive adhesive agent such as a wet pack, a plaster, or a surgical tape.

Such an adhesive tape generally includes a support and an adhesive layer provided on one surface of the support, and a release sheet releasably attached to the adhesive layer. After the adhesive tape is manufactured, the adhesive tape is cut into an appropriate size, and the adhesive tape is put into packaging bags separately for hygienic and physical protection, and is distributed and sold in this state. At this time, the packaging bag is torn at the time of use, the adhesive tape is taken out, and the release sheet is peeled off to expose the adhesive layer and is stuck to the sticking portion.

A frequent problem in use is that the release sheet is difficult to release. The release sheet is generally thin and flexible, and therefore, it is difficult to use, and it takes time to release. In order to improve this, various release sheets and pressure-sensitive adhesive tapes have been developed, which are required to have easy releasability of the release sheet and easy attachability of the pressure-sensitive adhesive tape, as disclosed in, for example, japanese patent laid-open nos. 2007 and 75602, 2007 and 75601, 3689807, and jp-a-50-133797.

These release sheets and pressure-sensitive adhesive tapes are all of a structure that is required to be convenient from the viewpoint of easy attachment of the pressure-sensitive adhesive tape. Although it is certainly convenient, there is no change in maintaining the form in which the pressure-sensitive adhesive tape is provided with the release sheet and the packaging bag, respectively, and the release sheet and the packaging bag become garbage after use.

The invention aims to provide an adhesive tape which can achieve the effect of saving resources while pursuing the easy attachment of the adhesive tape.

Disclosure of Invention

In order 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 tape packaging bag comprising a release sheet releasably adhered to the adhesive layer, wherein the release sheet is folded along a predetermined 1 st folding line into a 1 st part and a 2 nd part, the adhesive tape is folded along a predetermined 2 nd folding line into the 1 st part and the 2 nd part so that the adhesive layer faces outward, and the folded adhesive tape is sealed inside the folded release sheet. With such a configuration, a conventional packaging bag can be omitted. Further, when the release sheet is peeled off from the pressure-sensitive adhesive layer of the pressure-sensitive adhesive tape and opened, half of the pressure-sensitive adhesive layer is exposed, and thus the pressure-sensitive adhesive tape can be easily attached to the attachment site. In addition, in a state where the 1 st folding line and the 2 nd folding line are adjacent, the adhesive tape is preferably sealed inside the folded release sheet (see fig. 1), but the direction of the 1 st and the 2 nd folding lines is not limited to this, and a state where the 1 st folding line and the 2 nd folding line are arranged on the opposite side may be adopted (see fig. 13).

Preferably, the 1 st part of the release sheet and the 2 nd part of the release sheet have substantially the same shape, the 1 st part and the 2 nd part of the release sheet overlap each other, and the part for surrounding the adhesive tape is sealed at the overlapping part of the 1 st part and the 2 nd part of the release sheet. When the release sheet is sealed, the inside is blocked from the outside, and therefore the pressure-sensitive adhesive tape can be protected more hygienically and physically, and the components of the pressure-sensitive adhesive layer of the pressure-sensitive adhesive tape do not leak to the outside.

It is effective to form at least 1 convex point protruding outward at the outer edge of the surface bonding portion to be surface-bonded for sealing between the 1 st part and the 2 nd part of the release sheet. This is because: since the force is concentrated on the projection at the time of unsealing, the surface bonding is broken from the projection, and the unsealing is facilitated.

Preferably, a non-joined portion serving as a grip portion for unsealing is provided between the 1 st portion and the 2 nd portion of the release sheet. In addition, in the case where a mark that can be recognized by touch such as a notch is provided in the non-joined portion of either the 1 st portion or the 2 nd portion of the release sheet, even a person who is not good at eyes can easily grasp the direction in which the adhesive layer of the adhesive tape is exposed. Although the term "either one" is used, it is understood to include the case where different types of marks are provided, such as 1 notch in the 1 st part and 2 nd notch in the 2 nd part of the release sheet, and the marks may be provided in both the 1 st part and the 2 nd part.

Preferably, the adhesive force suppressing structure for suppressing the adhesive force between the adhesive layer of the part 1 of the adhesive tape and the release sheet is provided on at least a part of the release sheet. This is because, when the release sheet is opened, the adhesive layer is easily separated from the release sheet to expose the adhesive surface, and thus the adhesive layer is easily attached to the attachment site.

The release sheet is not particularly limited in material and structure as long as it protects the pressure-sensitive adhesive layer of the pressure-sensitive adhesive tape until the time of use, but is preferably a structure in which a cellophane film, a plastic film, and an aluminum foil are laminated from the outer layer, and then a plastic film is further laminated on the inner layer, and the adhesion-inhibiting structure is preferably a silicon-treated surface applied to at least a part of the portion of the release sheet to be adhered to the pressure-sensitive adhesive layer of the part 1 of the pressure-sensitive adhesive tape. Among various adhesion-inhibiting structures, silicon treatment has an advantage that the treatment can be performed relatively easily and inexpensively. As the adhesion-suppressing structure, embossing and/or sandblasting may be performed on the portion.

As another structure for easily releasing the release sheet from the pressure-sensitive adhesive layer of the pressure-sensitive adhesive tape, the 1 st portion of the pressure-sensitive adhesive tape is larger than the 2 nd portion of the pressure-sensitive adhesive tape, the 1 st portion has a protruding portion protruding from the 2 nd portion, and a temporary fixing means may be provided at least in a part of a portion facing the protruding portion in a portion of the release sheet on the 2 nd portion side of the pressure-sensitive adhesive tape. The adhesion of the support of the adhesive tape to the release sheet via the temporary fixing means is preferably higher than the adhesion of the adhesive layer to the release sheet. The temporary fixing means is preferably an adhesive, that is, a substance having an adhesive property to the support of the adhesive tape. By providing such a temporary fixing means on the release sheet, the 1 st part of the adhesive tape can be easily separated from the release sheet even without the silicon-treated surface or the like, and it is more preferable to provide the temporary fixing means in combination with the silicon-treated surface or the like.

In addition, the 1 st part and the 2 nd part of the adhesive tape may have substantially the same shape, and a temporary fixing device may be provided between the 1 st part and the 2 nd part. At this time, the adhesion of the temporary fixing means is preferably higher than the adhesion of the adhesive layer to the release sheet.

In the adhesive tape packaging bag configured as described above, the exposed portion of the adhesive layer of the adhesive tape, which appears while the release sheet is opened, is joined to a portion to be joined, and then the adhesive tape packaging bag is pulled so as to extend along the joining portion in the longitudinal direction of the release sheet and in the direction away from the adhesive tape, whereby the entire surface of the adhesive tape can be joined to the joining portion.

Effects of the invention

According to the adhesive tape packaging bag of the present invention, the adhesive tape has the release sheet, and any adhesive tape can be applied to other adhesive tapes as long as it is in a form of being packaged independently, and it is possible to provide an adhesive tape packaging bag which is energy-saving and easy to attach. That is, the adhesive tape packaging bag of the present invention can omit a packaging bag which is conventionally provided separately, and when the adhesive tape is stored, even if the packaging bag is omitted, the inside can be blocked from the outside by sealing the release sheet, so that the adhesive tape can be hygienically and physically protected.

When the pressure-sensitive adhesive tape is used, the release sheet is peeled off from the pressure-sensitive adhesive layer of the pressure-sensitive adhesive tape and the tape is opened, so that half of the pressure-sensitive adhesive layer is exposed, and the tape is easily attached to the attachment site. Further, since the adhesive tape is supported or reinforced on the remaining part of the release sheet after the half of the release sheet is released, the adhesive tapes are not joined to each other and cannot be used, which also makes the attachment easy. In addition, in the case of an adhesive agent capable of adhering an adhesive tape to a human body, that is, a plaster, a wet compress, a adhesive plaster, a surgical tape, an adhesive warmer (Kairo), or the like, even if the adhering portion is a back side or the like where it is difficult to adhere by one person, the adhesive tape can be easily adhered by one hand without dirtying the hands.

In addition, according to the adhesive tape packaging bag of the present invention, by providing the temporary fixing means between the release sheet and the support of the adhesive tape, the 1 st part of the adhesive tape can be easily separated from the release sheet even without a silicon-treated surface or the like, and half of the adhesive layer can be easily exposed.

The adhesive tape packaging bag of the present invention is manufactured in a unit of one sheet, and therefore is excellent in portability.

Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. In all the drawings, the same or corresponding portions are denoted by the same reference numerals, and redundant description thereof is omitted.

[ embodiment 1]

Fig. 1(a) to (c) are perspective views showing the steps of manufacturing the adhesive tape packaging bag 10 of the present invention. The adhesive tape packaging bag 10 includes an adhesive tape 14 having an adhesive layer 12 on one surface thereof, and a release sheet 16 having a shape covering the entire adhesive tape 14. Both the adhesive tape 14 and the release sheet 16 are preferably rectangular.

Fig. 2 is a sectional view showing a state where the release sheet 16 is attached to the adhesive tape 14. The adhesive tape 14 has a support 18 and an adhesive layer 12 laminated on one surface of the support, and a release sheet 16 is releasably attached to the adhesive tape 14.

The adhesive tape packaging bag of the present invention can be used for various applications such as labels, medical applications, cosmetics, decoration, masking, electronics, and others. In particular, adhesive tape packaging bags used for medical use, cosmetic use, and the like are used as packaging bags for adhesive agents that are usually applied to the skin, mucous membranes, and the like, such as wet packs, ointments, adhesive plasters, surgical tapes, pack preparations for cosmetics, and stick-on warmers (Kairo).

The material of the support 18 is not particularly limited as long as it can support the pressure-sensitive adhesive layer 12, and a film made of woven fabric, nonwoven fabric, plastic, or the like, a metal foil, or the like can be generally used. The support may have a single-layer structure or a laminated structure, and may have a structure in which a plurality of woven fabrics or nonwoven fabrics made of different materials are laminated, or a structure in which a plastic film, a metal foil, or the like is laminated with the woven fabrics or nonwoven fabrics.

The woven fabric or nonwoven fabric used in the present invention is not particularly limited, and any fabric or nonwoven fabric may be used as long as it is a fabric that can be used as a support for an adhesive tape by processing a fibrous material into a fabric shape, and includes a woven fabric processed into a fabric shape by integrating stitches such as circular knitting, warp knitting, weft knitting, and the like.

Preferable examples of the woven fabric or nonwoven fabric include woven fabrics or nonwoven fabrics composed of at least one resin fiber selected from the group consisting of polyester resins, polyethylene resins, and polypropylene resins, and among these, woven fabrics composed of polyester polyethylene terephthalate having little interaction with the components contained in the binder layer are preferable.

Examples of the plastic film include films formed using polyesters such as polyethylene terephthalate, polyamides such as nylon, polyolefins such as polyethylene and polypropylene, polyvinyl chloride, plasticized vinyl acetate-vinyl chloride copolymer, polyvinylidene chloride, ethylene-vinyl acetate copolymer, cellulose acetate, ethyl cellulose, ethylene-ethyl acrylate copolymer, polytetrafluoroethylene, polyurethane, and ionomer resin. When the adhesive tape of the present invention is used as an adhesive for medical use or cosmetic use, a material having sufficient stretchability or non-stretchability as an adhesive is preferably used for the support, and particularly, a knitted fabric (woven fabric) of polyethylene terephthalate is more preferable.

The woven fabric of the support 18 preferably has a weight per unit area (mass per unit) of 50 to 500g/m². The support 18 preferably has a modulus in the longitudinal direction (major axis direction) of 2 to 12N/5cm and a modulus in the transverse direction (minor axis direction) of 2 to 12N/5cm, measured according to JIS L1018. Here, the longitudinal direction refers to a flow direction in a process of producing a knitted fabric, and the lateral direction refers to a direction perpendicular to the longitudinal direction, that is, a width direction. When the modulus is less than 2N/5cm in the longitudinal or transverse direction, it is difficult to apply the tape while stretching wrinkles at the applied portion, and when the modulus is more than 12N/5cm in the longitudinal or transverse direction, the tape tends to be excessively stretched and wrinkles tend to be easily generated at the time of application. The modulus is a value at room temperature (25 ℃).

By using the support body 18, the temporary fixing by the temporary fixing device described later is facilitated, and the shape and structure of the support body 18 after the temporary fixing is removed are hardly changed. That is, for example, fuzz is not generated. In addition, the adhesive tape packaging bag 10 is easily folded in half without being expanded. Further, the so-called "wrinkle" is hardly formed in the folded portion at the time of pasting, and the pasting can be performed perfectly.

The adhesive component of the material constituting the pressure-sensitive adhesive layer 12 is not particularly limited as long as it has adhesiveness and can be adhered to a site to be adhered, and an acrylic adhesive component, a rubber adhesive component, a silicone adhesive component, or the like is preferably used as the adhesive base, and among them, a rubber adhesive component is particularly preferably used from the viewpoint of adhesive properties.

As a specific rubber-based adhesive component, either natural rubber or synthetic rubber can be used, and as the synthetic rubber, for example, a styrene-based block copolymer or polyisobutylene can be cited. Further, examples of the styrenic block copolymer include a styrene-butadiene-styrene block copolymer (SBS), a styrene-isoprene-styrene block copolymer (SIS), a styrene-ethylene/butadiene-styrene block copolymer (SEBS), and a styrene-ethylene/propylene-styrene block copolymer (SEPS). Specific examples of the styrene-based block copolymer include クレイトン D-1112, D-1111, D-1107 (trade name, manufactured by クレイトン Polymer (Co.)), JSR5000 or JSR5002 (trade name, manufactured by Nippon synthetic rubber (Co.)), クインタツク 3530, 3421 or 3570C (trade name, manufactured by Nippon ゼオン (Co.)), a linear triblock copolymer such as クレイトン D-KX401CS or D-1107CU (trade name, manufactured by クレイトン Polymer (Co.)), a branched block copolymer such as クレイトン D-1124 (trade name, manufactured by クレイトン Polymer (Co.)), ソルプレン 418 (trade name, manufactured by フイリツプペトロリアム (Co.)), and the like.

As the polyisobutylene, for example, high molecular to low molecular substances can be used, and examples thereof include オパノ - ル B10, B12, B12SF, B15, B15SF, B30SF, B50, B50SF, B80, B100, B120, B150, B200 (trade name, manufactured by BASF corporation), ビスタネツクス LM-MS, LM-MH, LM-H, MM L-80, MM L-100, MM L-120, and MM L-140 (trade name, manufactured by エクソン chemical Co., Ltd.).

Further, as the acrylic polymer, for example, a polymer or copolymer containing at least one (meth) acrylic acid ester represented by 2-ethylhexyl acrylate, methyl acrylate, butyl acrylate, hydroxyethyl acrylate, 2-ethylhexyl methacrylate, and the like can be used as the monomer unit, and for example, an octyl acrylate copolymer, a 2-ethylhexyl acrylate/N-vinyl-2-pyrrolidone/1, 6-hexanediol dimethacrylate copolymer, a 2-ethylhexyl acrylate/vinyl acetate/acrylic acid copolymer, a 2-ethylhexyl acrylate/2-ethylhexyl methacrylate/dodecyl methacrylate copolymer, a vinyl acetate/acrylic acid copolymer, a vinyl acetate/2-ethylhexyl acrylate/2-ethylhexyl methacrylate copolymer, a vinyl acetate/methacrylic acid copolymer, a vinyl acetate/acrylic, Methyl acrylate-2-ethylhexyl acrylate copolymer resin emulsion, a binder such as an acrylic polymer contained in an acrylic resin alkanolamine solution, Duro-Tak acrylic acid binder series (ナシヨナルスタ - チアンドケミカル), GELVA acrylic acid binder series (モンサント), SK ダインマトリダ - ム (Hoffy chemical), オイドラギツト series (Gutter business society), and the like.

One or more of the above-mentioned rubber-based, acrylic-based, silicon-based, and other adhesive bases may be used in combination.

When the adhesive tape of the present invention is used as a wet dressing agent for medical use, a plaster agent, or a pack agent for cosmetics, a water-soluble polymer may be used as the adhesive layer, and as such a water-soluble polymer, gelatin, agar, alginic acid, polymannan, carboxymethyl cellulose or a salt thereof, hydroxypropyl cellulose or a salt thereof, polyvinyl alcohol, polyacrylic acid or a salt thereof, or the like, or a substance crosslinked with an organic or inorganic crosslinking agent or at least one of them is preferably used.

In addition to the above-mentioned adhesive base, an adhesion-imparting agent, a softening agent, a dissolving agent, water, a thickener, a wetting agent, a filler, a crosslinking agent, a polymerization agent, a dissolution auxiliary agent, an absorption accelerator, a stabilizer, an antioxidant, an emulsifier, a surfactant, a pH adjuster, a drug, an ultraviolet absorber, and the like may be appropriately added to the adhesive layer.

The drug used when the adhesive tape of the present invention is used as an adhesive agent for medical use or cosmetic use is not particularly limited as long as it is a drug that is transdermally absorbed in vivo and exerts a pharmacological effect, and examples thereof include an anti-inflammatory agent, an analgesic agent, an antihistamine, a local anesthetic, a blood circulation promoter, an anesthetic, a neuroleptic agent, an antihypertensive agent, an antibacterial agent, and a vasodilator.

The release sheet 16 of the present invention can be used as long as it is a material that is generally used for a packaging bag of an adhesive tape. The release sheet 16 may be a single layer or a laminate, and the material of the structure is not particularly limited as long as the effect of the present invention can be produced. For example, it can be suitably selected from paper, nonwoven 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-vinyl alcohol copolymer, and the like.

Further, the release sheet may be one in which a printing ink, an adhesive, or the like is applied thereto, or one in which a thin film is provided by a method such as vapor deposition or sputtering. As the thin film, a thin film having excellent gas barrier properties and transparency, such as silicon oxide, magnesium oxide, and aluminum oxide, is preferably used in addition to a metal such as aluminum. 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 further preferable.

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

A release sheet 16 subjected to a silicon treatment described later is releasably attached to the adhesive tape 14 shown in fig. 1(a), and the state is shown in fig. 1 (b). At this time, the center line of the adhesive tape 14 parallel to the width direction thereof and the center line of the release sheet 16 parallel to the width direction thereof are attached in a state shifted from each other. The center line of the release sheet 16 serves as the 1 st folding line for forming the adhesive tape packaging bag 10.

The release sheet 16 is folded along the 1 st folding line together with the adhesive tape 14 to form the 1 st part 20 and the 2 nd part 22 having the same shape. The adhesive tape 14 is sealed in a folded state inside the folded release sheet 16, thereby completing the adhesive tape packaging bag 10 of the present invention (fig. 1 (c)). In this state, it is understood that the folding line (2 nd folding line) of the adhesive tape 14 is disposed adjacent to the 1 st folding line of the release sheet 16.

As a method of sealing the adhesive tape 14, a method of sealing a portion surrounding the adhesive tape 14 in an overlapping portion of the 1 st portion 20 and the 2 nd portion 22 of the release sheet 16 is preferable. When the release sheet 16 is sealed, the inside is blocked from the outside, and therefore, the adhesive tape 14 can be protected more hygienically and physically, and there are advantages that the components contained in the adhesive layer of the adhesive tape packaging bag 10 do not leak to the outside and are not volatilized.

As a method of sealing the periphery of the release sheet 16, a method using an adhesive or the like is conceivable in addition to the heat sealing method. Further, the periphery of the release sheet 16 may be fixed by an adhesive tape. By configuring the adhesive tape packaging bag 10 in this manner, the release sheet 16 also functions as a packaging bag, and thus a single packaging bag that has been conventionally provided can be omitted.

In order to avoid the sharp corner of the completed adhesive tape packaging bag, it is effective that the release sheet has a substantially rectangular shape such that part, preferably all, of the corner of the completed adhesive tape packaging bag is rounded. Fig. 1 (c) shows a state in which 2 corners are rounded.

In addition, when the edge of the whole or a part of the release sheet is bonded, for example, in order to avoid damage to the bonding portion or the periphery thereof by the edge of the release sheet, the edge may be formed in a waveform, a pulse shape, or a rectangular shape, or the extreme end of the edge may be formed without bonding (see (a) to (d) of fig. 3).

In the present invention, the release sheet 16 preferably has an adhesion-inhibiting structure that inhibits adhesion of the pressure-sensitive adhesive layer 12 of the 1 st portion of the pressure-sensitive adhesive tape 14 to the release sheet 16. As this adhesion force suppressing structure, a structure is conceivable in which a peeling treatment is performed on the entire surface of the side of the release sheet 16 that contacts the pressure-sensitive adhesive tape 14, but the peeling treatment may be performed only on the portion indicated by the hatching in fig. 1 (a). In addition, since the adhesion-suppressing structure is intended to facilitate the peeling of the 1 st portion 26 of the adhesive tape 14 from the release sheet 16 when the adhesive tape packaging bag 10 is opened, the peeling treatment may be performed only on the portion of the release sheet 16 that is in contact with the 1 st portion 26 of the adhesive tape 14, or only on a further part of the portion as long as the purpose can be achieved.

The peeling treatment includes a method of using a peeling agent, and a method of physically facilitating peeling such as embossing or sandblasting. As the release agent, any of a silicon-based release agent, an alkyl chain-based release agent, a condensed wax-based release agent, and the like can be used, and among them, so-called silicon treatment using a silicon-based release agent is preferable. Silicon processing has the advantage of being relatively easy and inexpensive to perform. When the release sheet 16 is opened when the adhesive tape packaging bag 10 is used, the adhesive layer 12 is easily detached from the release sheet 16 by the silicon treatment, and the adhesive layer 12 is exposed, and thus the adhesive tape packaging bag can be easily attached to the attachment site.

As another means for easily peeling the release sheet 16 from the adhesive layer 12 of the adhesive tape 14, a means capable of temporarily holding at least a part of the support of the adhesive tape, that is, a temporary fixing means can be provided on the release sheet 16. The temporary fixing means is not particularly limited, and for example, magnetic force, electrostatic force, or physical force, such as a hook and loop fastener, a double-sided tape, an adhesive, or an adhesive may be used, or welding, thermal bonding, strong pressure, molding, or the use of a hot-melt adhesive may be used depending on the material, properties, and the like of the dummy bonding, the release sheet 16, or the support 18. In particular, when the layer to be the inner side of the release sheet 16 is made of a thermoplastic material that melts at a predetermined temperature and the support 18 of the adhesive tape 14 is made of, for example, a woven fabric, the inner layer of the release sheet 16 can be melted to penetrate the woven fabric of the support 18 and be solidified, and therefore, temporary fixing by thermal bonding is effective. In addition, even in the case where the release sheet 16 does not have thermoplasticity, it is conceivable that the material of the support 18 contains a thermoplastic material to perform thermal bonding. Alternatively, a plurality of projecting portions may be formed by embossing the surface of the release sheet 16 on the inside of the 2 nd portion 22, and these projecting portions may be held by the support body 18.

Various temporary fixing means as described above may be used, and among them, a method using pseudo bonding or hot melt adhesive, or a method based on thermal bonding is particularly preferable. In the method using the pseudo bonding or the hot melt adhesive, when the adhesive tape 14 is folded along the folding line of the release sheet 16 into the 1 st part 26 and the 2 nd part 28 together with the release sheet 16, the 1 st part 26 of the adhesive tape 14 is larger than the 2 nd part 28 of the adhesive tape 14, the 1 st part 26 has a protruding part protruding from the 2 nd part 28, and the pseudo bonding or the hot melt adhesive is used in the part 24 facing the protruding part in the part of the release sheet 16 on the 2 nd part 28 side of the adhesive tape 14. The adhesion force of the joining portion 24 to the support 18 of the adhesive tape 14 is higher than the adhesion force of the adhesive layer 12 to the release sheet 16, and even if there is no adhesion force inhibiting structure such as a silicon-treated surface, the 1 st portion 26 of the adhesive tape 14 can be easily separated from the release sheet 16 when the adhesive tape 10 is used. It is more preferable to form such a joint portion 24 in combination with the silicon processed surface.

On the other hand, in the case of temporary fixing by thermal bonding, the portion 24 as described above is not formed. The temporary fixation by heat sealing is understood to be that after the release sheet 16 is folded into the state of fig. 1 (c), and the outer peripheral portion of the portion where the 1 st part 20 and the 2 nd part 22 overlap is sealed, for example, heat sealed, or heat sealed simultaneously with the heat sealing. After the thermal bonding, the outer peripheral portion of the peeled sheet 16 may be sealed by heat sealing or the like.

The temporary fixing means may be such that the adhesion force of the non-adhesive surface 30 of the support 18 of the pressure-sensitive adhesive tape 14 to the release sheet 16 (the adhesion force of the joint portion 24 as the temporary fixing means) is higher than the adhesion force (adhesive force) of the pressure-sensitive adhesive layer 12 to the release sheet 16. That is, the adhesion force of the support 18 to the release sheet 16 via the temporary fixing device, the adhesion force (adhesive force) of the pressure-sensitive adhesive layer 12 of the pressure-sensitive adhesive tape 14 to the attachment site, and the adhesion force of the pressure-sensitive adhesive layer 12 of the pressure-sensitive adhesive tape 14 to the release sheet 16 are in the following relationship.

Adhesion of the pressure-sensitive adhesive layer 12 to the site of application

Adhesion of support 18 to release sheet 16 via temporary fixing means

Adhesion of adhesive layer 12 to Release sheet 16

The term "pseudo bonding" as described in the technical field patent table, page 336 of the general term "bonding" 21, which is available from the aforementioned office homepage, means that the bonding is not performed under normal conditions, but a pseudo adhesive produced by adding an additive to an adhesive can be used as a characteristic of bonding under special pressure conditions. The pseudo adhesive may be any of various known pseudo adhesives. Such a dummy adhesive may be applied to the 2 nd part 22 of the release sheet 16 at a portion facing the protruding portion, and may be provided in a dot shape, may be applied to the entire surface of the protruding portion of the support 18, or may be provided in a linear or dot shape at the protruding portion. In addition, a dummy bonding resin layer may be formed at a necessary portion without applying a dummy adhesive.

The operation and effect of the pressure-sensitive adhesive tape packaging bag 10 of the present embodiment will be described below with reference to fig. 4 to 7.

Fig. 4(a) is a perspective view of the adhesive tape packaging bag 10 of the present embodiment. Compared with the conventional adhesive tape, the adhesive tape has no packaging bag independent of the release sheet, so that resources are saved. The adhesive tape packaging bag 10 of the present invention is produced in units of one sheet, and therefore is excellent in portability.

Fig. 4 (b) shows how the sealed release sheet 16 is opened from one end of the closed portion around the release sheet 16. Release sheet 16 is opened while being peeled from adhesive layer 12 of part 1 26 of adhesive tape 14.

Then, as shown in fig. 4 (c), when the release sheet 16 is completely opened to return to the flat shape before folding, the 1 st portion 26 of the adhesive tape 14 is completely peeled off from the release sheet 16, and the adhesive layer 12 of the 1 st portion 26 is exposed. In particular, when the release sheet 16 is subjected to a silicon treatment for suppressing the adhesion between the pressure-sensitive adhesive layer 12 of the 1 st portion 26 of the pressure-sensitive adhesive tape 14 and the release sheet 16, the state of fig. 4 (c) can be easily formed. Further, when the temporary fixing means 24 such as a pseudo adhesive or a hot melt adhesive is provided on the release sheet 16, if the adhesion force of the support 18 of the pressure-sensitive adhesive tape 14 to the release sheet 16 via the temporary fixing means is designed to be higher than the adhesion force of the pressure-sensitive adhesive layer 12 to the release sheet 16, the state of fig. 4 (c) can be easily formed even without a silicon-treated surface.

Fig. 5 to 7 show the form of the adhesive tape of the present invention used as an adhesive agent for medical use, cosmetic use, and the like, and the adhesive tape can be used for other applications by the same method. That is, a method of attaching the adhesive tape packaging bag in which the adhesive layer 12 of the 1 st portion 26 of the adhesive tape 14 is exposed to the attachment portion is shown. First, the adhesive tape packaging bag is held by one hand and brought into contact with the attachment site or the vicinity of the attachment site as shown in fig. 5. Then, as shown in fig. 6, in a state where the 1 st portion 20 of the release sheet 16 is gripped, the release sheet 16 is pulled along the skin in the longitudinal direction of the release sheet 16 and in a direction in which the release sheet 16 is separated from the adhesive tape 14. As release sheet 16 is pulled, portion 2 28 of adhesive tape 14 is peeled from release sheet 16 and simultaneously adhered to the attachment site. In particular, since the release sheet 16 is attached while being pulled, the adhesive tape 14 can be attached to the adhesive tape 14 without generating wrinkles. Fig. 7 shows a state where the entire adhesive tape 14 is attached to the attachment portion.

The adhesive tape of the present invention can be firmly held on the hand because the thumb of the hand on which the adhesive tape is placed can be placed on the 1 st part 20 of the release sheet 16 released from the adhesive layer 12. Therefore, there is little risk of the adhesive tape falling down when being brought into contact with the attachment site, and also, there is little risk of the adhesive tape shaking or hanging down in an undesired direction by gravity when being attached, so that the attachment can be performed with a good sense of sight at the attachment site. Even if the pasting part is a back which is difficult to paste by one person, the pasting part can be pasted by one hand easily.

In addition, in the above-described operation, the adhesive layer is less likely to contact the skin other than the attachment site. The adhesive tape is sanitary because the adhesive layer does not stick to fingers and the like, which is often experienced when using a conventional adhesive tape, and the adhesive tape 14 is supported or reinforced on the 2 nd part 22 of the release sheet 16 after the 1 st part 20 of the release sheet 16 is peeled off, so that the adhesive tape is not joined to each other and the adhesive cannot be used.

However, in order to facilitate the opening of the adhesive tape packaging bag, it is also effective to use the so-called Easy Peel (Easy Peel) technique as a method of sealing the periphery of the 1 st part 20 and the 2 nd part 22 of the release sheet 16. The easy peel property is an easy peel property as described in the technical field patent table, commonly 21 "joint" page 335 (www.jpo.go.jp/shiryou/s _ sonota/map/ippan21/4/4-3-1.htm), which is available from the office homepage, and indicates a property of being easily peeled off when a container or package is sealed by heat sealing and opened. The easy peel is of various types, specifically, a cohesive peel type in which the adhesive layer itself between the 1 st part 20 and the 2 nd part 22 of the peel sheet 16 is broken and peeled off; an interlayer peeling type in which the bonding strength between the adhesive layer and the 1 st part 20 or the 2 nd part 22 is reduced in advance, and the 1 st part 20 or the 2 nd part 22 is peeled from the adhesive layer at the time of opening; in the case where a sheet having a polyethylene layer disposed on the surface thereof is used as the release sheet 16, for example, an adhesive layer having a 2-layer structure composed of a resin layer mainly composed of high-density polyethylene and an easily peelable resin layer obtained by adding a resin causing cohesive failure to low-density polyethylene can be used as the easily peelable adhesive layer.

In order to facilitate the opening of the release sheet, a method of providing a notch at the edge or providing a fragile portion for opening the release sheet may be suitably used.

For the same purpose, as shown in fig. 8(a) or (b), the non-joined portion 40 may be pinched without joining the end portions of the 1 st portion 20 and the 2 nd portion 22 of the release sheet 16. In particular, when the shape is as shown in fig. 8 (b), the non-joined portion 40 can be provided wider, and the user can easily grip the non-joined portion. Of course, the combination of the above-described easy peeling technique makes it easier to open the package.

Further, the adhesive tape packaging bag 10 shown in fig. 9(a) and (b) is also easy to open, and the non-joined portion 40 is pinched without joining the entire end portions of the 1 st portion 20 and the 2 nd portion 22 of the release sheet 16. In this case, the non-joined portion 40 has an area larger than the entire width of the packaging bag 10, and thus has an advantage of being easier to grip. Further, similarly to the above, the opening can be further facilitated by applying the easy peeling technique to the seal portion (the portion of the one-dot chain line), but if the portion indicated by the two-dot chain line in fig. 9(a) is formed in advance as the fragile line by, for example, heating, the seal portion can be easily cut across along the fragile line and the 1 st portion 20 can be cut into a desired shape even if the seal portion is not formed in the easy peeling form.

As shown in fig. 9(a), it is also preferable that a mark 50 which can be recognized by a touch such as a notch is provided on one portion of the release sheet 16, for example, on the edge of the non-joined portion 40 of the 1 st portion 20. In the present invention, when opening the adhesive tape packaging bag 10, as will be described later, the adhesive layer 12 of the adhesive tape 14 is directed upward, so that the attachment work (see fig. 4 (c)) is facilitated, and by providing the mark 50 that can be recognized by touch on at least one portion of the release sheet 16, a person having poor eyesight can also determine the upper and lower sides of the packaging bag 10. The mark 50 that can be recognized by the touch may have various shapes such as a shape shown in fig. 3, embossing, and protrusion, in addition to the notch.

The structure of fig. 9 (b) is also one in which the non-joined portion 401 of the 1 st portion 20 is longer than the non-joined portion 402 of the 2 nd portion 22, and the upper and lower portions can be determined by tactile sensation. Such a marking can of course also be applied to the structure shown in fig. 8. Further, as shown in fig. 9 (b), the non-joined portion 401 can be more easily pinched by shifting the positions of the edge portions of the non-joined portions 401, 40 of the 1 st portion 20 and the 2 nd portion 22 to provide a step difference.

[ 2 nd embodiment ]

Fig. 10 is a schematic explanatory view showing the adhesive tape packaging bag 10 which is devised to facilitate opening. The adhesive tape packaging bag 10 shown in fig. 10 is characterized in the shape of the heat-sealed portion 60 formed at the overlapping portion of the 1 st part 20 and the 2 nd part 22 of the release sheet 16. Other structures are the same as those of embodiment 1, and therefore, description thereof is omitted.

As shown in fig. 10, the heat seal portion 60 is provided in a portion 60a opposite to the folded portion 55 of the adhesive tape packaging bag 10 and in edge portions 60b and 60c between the portion 60a and the folded portion 55. The heat-seal lands 60b and 60c on both sides are linear, as in embodiment 1. The heat-seal land 60a between the heat-seal lands 60b and 60c is provided at a position apart from the end, and the portion 65 is not joined, so that the portion 65 can be pinched and opened.

The heat-seal land 60a is formed in a mountain-like or triangular zigzag shape as shown in the figure. In the heat-sealed portion 60a having such a shape, when the part 65 is pinched and the 1 st part 20 and the 2 nd part 22 of the release sheet 16 are pulled in the direction of separating from each other, the stretching force is concentrated on the top of either one of the ridges of the heat-sealed portion 60a, and thus the rupture of the heat-sealed portion 60a starts from the top thereof. For example, in fig. 10, when opening from the upper right end, the force is concentrated at the top of the hill as shown by symbol 68. In particular, in the shape shown in fig. 10, since the top of the mountain is a point, even if the tensile force is small, the force is concentrated at one point, and thus the fracture is easily started. When the heat-seal land 60a starts to rupture, a larger tensile force does not have to be applied, and the rupture propagates to other parts starting from the rupture start point, and the entire heat-seal land 60 ruptures, so that the adhesive tape packaging bag 10 is in the state of fig. 4 (c).

The height H and pitch P of the ridges of the heat seal portion 60a can be appropriately determined. However, when P is larger than H, the angle of the top of the mountain is increased, which impairs the effect of force concentration. When P is small, the tensile force applied to the portion 65 is dispersed to the top of 2 or more mountains, and a large force is required for opening. On the other hand, if H is small, a large force is required to open the heat-sealed portion close to the linear one. In view of such a point, it is preferable that H is about 10mm and P is about 10 to 20 mm.

Fig. 11(a) shows a modification of the heat-seal land 60 of fig. 10, in which the inner edge of the heat-seal land 60a is formed linearly. By forming one edge in a linear shape in this way, the heat-seal land 60 feels smooth when broken.

Further, since the heat-seal land 60 is easily broken by concentrating the force at one point, only one projection 70 projecting toward the nip portion 65 may be formed in the heat-seal land 60a as shown in fig. 11 (b). In the structure of fig. 11 (b), the heat-seal land 60a is formed in a gentle ridge shape in a portion other than the projections 70, so that the crack from the projections 70 is easily propagated to other portions.

Further, the method of joining the 1 st part 20 and the 2 nd part 22 of the release sheet 16 is not limited to heat sealing, and it is also conceivable to form at least one convex point protruding outward on the outer edge of the surface joining portion formed by a method other than adhesive by using a method such as adhesive, thereby obtaining the same easy-sealing property as the heat sealing portion 60a shown in fig. 10 and 11.

Fig. 12 shows a structure shown in fig. 8 (b), to which the above-described concept of providing the projections 68 and 70 in the heat seal portion is applied. In this structure, the corner in the nip portion 65 faces the convex portion 69 of the heat-seal land 60. Since the user opens the package 10 by pinching the corner portion, the force is likely to be directly applied to the convex portion 69, and the package is easily peeled.

The structure of fig. 9 (b) can also be applied to the structures of fig. 10, 11(a), (b), and 12. That is, although not shown, for example, in the configuration of fig. 10, one portion 65 of the 1 st portion 20 and the 2 nd portion 22 may be made longer than the other portion 65, and in this case, the portion 65 can be gripped very easily, which is effective for the user.

Although the preferred embodiments 1 and 2 of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments.

For example, in the above description, the case where the release sheet and the support are substantially rectangular has been described, but they may be square, circular, oval, oblong, or the like, and may follow the shape of various planar patterns.

The production method of the present invention is not particularly limited, and the production method can be performed through a general production process of the adhesive tape, a joining process of the release sheet and the adhesive tape, and a superposing process of the release sheet.

Further, in the above embodiment, the 1 st part 20 and the 2 nd part 22 of the release sheet 16 are formed so as not to be separable, but a fragile line (for example, a sewing hole, a line which is easily broken by heating, or the like) may be provided between the two so that the 1 st part 20 and the 2 nd part 22 of the release sheet 16 can be separated when the release sheet 16 is peeled from the 1 st part of the adhesive tape 14. This is because, when some obstacle or the like exists around the portion to be bonded, the release sheet may be cut small and may be bonded relatively easily.

In the above embodiment, the edge portions of the 1 st portion 20 and the 2 nd portion 22 of the release sheet 16, which overlap each other, are heat-sealed, and the bent portions are not particularly mentioned, but as shown in fig. 13, the same processing as that of the other edge portions may be performed for the bent portions 55. In this case, the same seal portions are formed on all the four sides of the adhesive tape packaging bag 10, and therefore, the adhesive tape packaging bag is beautiful.

As shown in fig. 14, the adhesive tape 14 may be disposed between the 1 st portion 20 and the 2 nd portion 22 of the release sheet 16 so that the folding line (1 st folding line) 42 of the release sheet 16 and the folding line (2 nd folding line) 44 of the adhesive tape 14 face in opposite directions. Further, it is also contemplated that the 1 st bend line 42 and the 2 nd bend line 44 are not parallel and may be formed at 90 degrees or other angles.

Fig. 15 shows another embodiment of the present invention, in which the area of the 1 st portion 26 of the adhesive tape 14 is substantially the same as the area of the 2 nd portion 28, in other words, the 1 st portion 26 and the 2 nd portion 28 are substantially the same shape. At this time, the temporary fixing means 24 is not provided at the 2 nd portion 22 of the release sheet 16, but needs to be provided between the 1 st portion 26 and the 2 nd portion 28 of the adhesive tape 14. The temporary fixing device 60 may be a pseudo adhesive or a hot melt adhesive as in the above embodiment, and if the support 18 of the adhesive tape 14 is made of a nonwoven fabric, a method of winding fibers may be employed.

Examples

For the adhesive, 20 parts of a styrene-isoprene-styrene block copolymer, 20 parts of polyisobutylene, 45 parts of a fluid wax, and 15 parts of hydrogenated rosin glycerin ester were mixed and stretched into a polyethylene terephthalate fabric to obtain an adhesive tape. A laminated film (thickness: 80 μm) of polyethylene terephthalate, aluminum, and polyethylene was cut to an area larger than that of the adhesive tape, and one surface of the whole was subjected to a silicon treatment as an adhesion-inhibiting structure. Then, an adhesive tape is placed on the surface provided with the adhesion-suppressing structure of the release sheet, and an adhesive is applied to a part of the portion where the adhesive tape is not placed as a temporary fixing means. Then, the release sheet is folded so as to wrap the adhesive tape, and a part of the adhesive tape is brought into contact with the temporary fixing device, and the edge portion is heat-sealed. Thus, the pressure-sensitive adhesive tape packaging bag of the form shown in fig. 1 (c) and 4(a) was obtained.

When such a pressure-sensitive adhesive tape packaging bag is opened, as shown in fig. 4 (c), the pressure-sensitive adhesive tape that has been folded remains on the side of the release sheet that has been opened. After that, the adhesive tape is attached to the skin in the order shown in fig. 5 to 7, and the adhesive tape can be reliably and smoothly attached to the skin without wrinkles and easily.

According to the gist of the above-described embodiment, a plurality of adhesive tape packaging bags having the shapes shown in fig. 10 were produced by changing the formation conditions of the heat-sealed portions, the force required for opening the heat-sealed portions (the portion indicated by the reference numeral 60a in fig. 10) was measured by an opening force test, and the performance of each packaging bag was evaluated by a functional test.

In the opening force test, a tensile tester AGS-1kg NG (manufactured by Shimadzu corporation) was used. Then, the opening end of the packaging bag (the upper portion of the pinch portion 65 of the 1 st portion 20 and the 2 nd portion 22 in fig. 10) was attached to a holding jig, and the force per 25mm width required for opening the heat-sealed portion (the portion indicated by the reference numeral 60a in fig. 10) was measured when the packaging bag was pulled in the opposite direction at an opening speed of 300mm/min (so-called T-shaped opening). The results are shown in the following table.

[ Table 1]

Very good (good sealing and good unsealing)

Good O (good sealing property or good unsealing property)

X difficult to open or poor in sealing property

From the above table, it is understood that the results of the functionality test are "good" when the force required to open the packaging bag is in the range of 0.5 to 10N/25mm, and particularly "particularly good" when the force is in the range of 1 to 5N/25 mm. From this result, the forming conditions of the heat-sealed portion are preferably set so that the force required to open the packaging bag is in the range of 0.5 to 10N/25mm, more preferably in the range of 1 to 5N/25 mm. Thus, the pressure-sensitive adhesive tape packaging bag can be easily opened even for weak elderly people and patients, and has good sealing properties.
