JP6163656B2 - Hole closing label, hole closing label continuous body, and method for producing the continuous body - Google Patents

Description

  The present invention relates to a label affixed to a release paper so as to be peelable and capable of closing a hole of an object to be pasted, such as a handle hole of a cardboard box, a continuous body thereof, and a production of the continuous body Regarding the method.

  A cardboard box is formed with a handle hole, and foreign matter may enter the cardboard box from the handle hole. In particular, when the stored items stored in the cardboard box are pharmaceuticals, precision instruments, etc., there is a risk of quality deterioration or failure due to the entry of the foreign matter.

In view of such a problem, Patent Document 1 provides a release paper, a base material affixed to the surface of the release paper with an adhesive, and provided in the plane of the release paper and the base material corresponding to the handle holes. There is disclosed a dustproof label with a release paper having a formed opening and a stretchable film laminated on the surface of a substrate so as to close the opening.
Such a dustproof label is peeled off from the release paper, and is used by being attached to the outer surface of the cardboard box via an adhesive while aligning the opening of the base material with the handle hole of the cardboard box.
Since the opening of this dustproof label is blocked by a stretchable film, foreign matter can be prevented from entering from the handlehole, and the stretchable film stretches appropriately, so the dustproof label closes the handlehole. The cardboard box can be transported by placing the hand on the handle hole as it is.

However, the dustproof label with release paper of Patent Document 1 has a problem that distortion is likely to occur because an opening is formed in the release paper.
Specifically, the dust-proof labels of Patent Document 1 are provided in the form of a label continuum in which a plurality of dust-proof labels are affixed on a release paper at predetermined intervals.
This label continuum is formed by punching out a raw material sheet in which a release paper and a base material are laminated via an adhesive, and forming a plurality of holes (openings) in the surface of the raw material sheet. It is produced by laminating a stretchable film on top and removing the substrate and stretchable film (other than the release paper) leaving the periphery including the holes.
The obtained label continuum is wound around a roll and stored. At the time of use, the continuum is pulled out from the roll, and the individual dustproof labels are peeled off from the release paper.

However, a hole (opening) is formed in the release paper, but the stretchable film that closes the hole is easy to extend. Therefore, when the label continuous body is manufactured or transported (the continuous body is wound or continuous) In many cases, the release paper is distorted when the dustproof label is peeled off from the release paper. Further, when the stretched film and the release paper are laminated, the release paper may be distorted.
If the continuous label is wound on a roll while the release paper is distorted, the dustproof label is distorted and wrinkled. Further, even if the release paper and the label are wound on the roll so as not to be distorted, if the release paper is subsequently distorted when the dust-proof label is peeled off, the dust-proof label may not be peeled cleanly.

[Continuous hole closing label and hole closing label according to the first embodiment]
FIGS. 1 and 2 show the hole closing label continuous body 10 according to the first embodiment, and FIGS. 3 and 4 show the hole closing label 1 attached with release paper.
In FIG. 1 and FIG. 2 (a), a continuous label 10 for hole closing is attached to an elongated release paper original 2M and to the release paper original 2M so as to be peelable along the longitudinal direction. A plurality of hole closing labels 1.
3 and 4, the release paper sticking hole closing label 1 has a release paper 2 and a hole closing label 1 attached to the release paper 2 so as to be peelable. The planar view shape of the release paper 2 in the illustrated example is the same as the planar view shape of the hole closing label 1, but the release paper 2 may be larger than the hole closing label 1.
“Peelable” means that it can be easily peeled off by human power.

In the hole closing label 1 of the present invention, a stretchable film 5 for closing the opening 4 is attached to the surface of a label substrate 3 having an adhesive layer 38 on the back surface and having the opening 4 in the surface. ing. The pressure-sensitive adhesive layer 38 provided on the back surface of the label base material 3 is referred to as a “base material pressure-sensitive adhesive layer”.
The shape and size of the opening 4 (hole) are not particularly limited, but the hole closing label 1 of the present invention is used so that a hand or the like can be put on the hole while closing the hole of the object to be stuck. Therefore, it is preferable that the opening 4 has substantially the same shape as the hole of the packaged object or a shape slightly smaller or larger than that.
The shape of the opening 4 in plan view is appropriately designed according to the shape of the hole in the object to be pasted. For example, as shown in FIGS. 1 and 3, the opening 4 has a substantially rectangular shape (or a horizontally long oval shape). Formed). The hole closing label 1 having the substantially rectangular (or oblong oval) opening 4 can be suitably used for a handle hole of a storage box such as a cardboard box.

Since the hole closing label 1 constituting the hole closing label continuous body 10 and the release paper sticking hole closing label 1 have the same configuration, both will be described below together, and the same terms and symbols will be used. use.
In the continuous hole closing label 10, a plurality of the hole closing labels 1 are affixed side by side at a predetermined interval in the longitudinal direction of the long release sheet original fabric 2M. Two rows of the hole closing labels 1 arranged in the longitudinal direction are provided in the width direction of the release paper 2M.
However, in the illustrated example, the case where two rows of hole closing labels 1 are provided in the width direction of the release paper original fabric 2M is illustrated, but the hole closing label continuous body 10 of the present invention is used for hole closing. The label 1 may be provided with only one row in the width direction of the release paper original fabric 2M, or may be provided with three or more rows.

  The length in the longitudinal direction and the length in the width direction of the long release paper original fabric 2M are not particularly limited and can be set as appropriate. The longitudinal length of the long release paper original fabric 2M is, for example, 5 m or more, and preferably 10 m or more. The length in the width direction of the original release paper 2M is not less than the length in the width direction of the hole closing label 1.

The release paper sheet 2M and the release paper 2 each have a sheet material 21, and a release surface portion 2a and a non-release surface portion 2b provided on the surface of the sheet material 21. The release paper original 2M is a long belt-like sheet in which an opening corresponding to the opening 4 is not formed, and the release paper 2 is a sheet-like shape in which an opening corresponding to the opening 4 is not formed. This is a sheet.
The release surface portion 2a and the non-release surface portion 2b are arranged in a sea island shape on the surface of the release paper original fabric 2M and the surface of the release paper 2. The release surface portion 2a exists as a sea region, and the non-release surface portion 2b exists as an island region.
However, as for the release paper original fabric 2M, a plurality of independent non-release surfaces 2b are arranged at intervals in the release surface 2a which is the sea region.
The release surface portion 2a is a surface on which the pressure-sensitive adhesive is difficult to adhere and enhances the releasability of the pressure-sensitive adhesive attached thereto. The non-release surface portion 2b is a surface on which the pressure-sensitive adhesive normally adheres and the pressure-sensitive adhesive attached thereto is difficult to peel off.

  Although the planar view shape of the non-molding surface portion 2b is not particularly limited, it can be formed in the same shape and size as the opening portion 4 formed in the label substrate 3 or a similar shape slightly larger or slightly smaller than that. Preferably, the non-release surface portion 2 b is formed in a similar shape that is the same shape as or slightly smaller than the opening 4, and more preferably is formed in a similar shape that is slightly smaller than the opening 4. If the non-molding surface portion 2b is larger than the shape of the opening 4, the base adhesive layer 38 strongly adheres to the non-molding surface 2b outside the score line 6 (corresponding to the periphery of the opening 4), and the hole is blocked. There is a possibility that it will be difficult to peel off the label 1 for use from the release paper 2.

In the illustrated example, the non-release surface portion 2 b is formed in a similar shape slightly smaller than the opening 4. In this case, the size of the non-release surface portion 2b can be set as appropriate. For example, the non-release surface portion 2b is formed so that the peripheral edge of the non-release surface portion 2b is 0.5 mm to 2 mm shorter than the peripheral edge of the opening 4 (cut line 6). it can.
In addition, although the planar view shape of the non-release surface part 2b is not represented in FIG. 1 thru | or FIG. 4, since it has represented in drawing of the description column of the manufacturing method mentioned later, please refer to it.

  The sheet material 21 constituting the release paper original fabric 2M and the release paper 2 is not particularly limited, and examples thereof include paper, synthetic paper, synthetic resin films, and laminated sheets thereof. When paper is used as the sheet material 21, it is preferable to provide a known sealing layer (not shown) on the surface. By providing the sealing layer, the penetration of the release agent can be suppressed. For forming the sealing layer, a conventionally known method can be employed, and examples thereof include a method of applying an ink (so-called medium ink) containing no pigment on the surface of the sheet material 21. In addition, when the sealing layer is provided, the sealing layer may be provided at least in a range where the release agent is applied. However, in consideration of coating workability, the sealing layer is provided on the entire surface of the sheet material 21. It is preferable to form.

In the illustrated example, a release agent is applied to the formation range of the release surface portion 2 a in the surface of the sheet material 21 to form the release layer 22. The surface of the release layer 22 becomes the release surface portion 2a, and the range where the release layer 22 is not provided in the surface of the sheet material 21 becomes the non-release surface portion 2b.
A conventionally well-known thing can be used for a mold release agent, and the mold release agent containing silicone resin is mentioned typically.
The thickness of the release layer 22 is usually about 0.1 to 3 μm.

A label base material 3 is laminated on the surfaces of the release paper raw fabric 2M and the release paper 2 with a base adhesive layer 38 interposed therebetween.
The label substrate 3 includes one non-release surface portion 2b of the release paper 2 and a release surface portion 2a around the non-release surface portion 2b, and a substrate pressure-sensitive adhesive layer 38 is provided on the surface of the release paper 2 (release paper original fabric 2M). Are attached.

The substrate pressure-sensitive adhesive layer 38 is provided on substantially the entire back surface of the label substrate 3 by applying a pressure-sensitive adhesive to the back surface of the label substrate 3. The back surface of the label substrate 3 is non-releasing, and the surface of the substrate pressure-sensitive adhesive layer 38 is strongly bonded to the back surface of the label substrate 3. The substrate pressure-sensitive adhesive layer 38 does not usually peel from the label substrate 3.
The thickness of the base adhesive layer 38 is not particularly limited and is, for example, 5 μm to 30 μm.
The pressure-sensitive adhesive is not particularly limited and typically includes a pressure-sensitive pressure-sensitive adhesive. The pressure-sensitive adhesive is an adhesive that exhibits adhesiveness at room temperature and adheres to an object to be adhered by pressing. Examples of the pressure-sensitive adhesive include an adhesive mainly composed of an acrylic resin, an adhesive mainly composed of a styrene rubber such as styrene isoprene rubber (SIS), and a urethane adhesive. Examples of the properties of the pressure-sensitive adhesive include an emulsion type, a solvent-soluble type, and a hot melt type.

The label substrate 3 is not particularly limited, and a synthetic resin film, paper, synthetic paper, a foamed resin film, a metal vapor deposition film, or a laminated film (for example, a synthetic resin film and a laminated film of paper) or the like. Can be mentioned.
The label base material 3 may be subjected to desired design printing as necessary.
Although the thickness of the label base material 3 is not specifically limited, Usually, it is about 20 micrometers-200 micrometers.

A release surface portion 3a is provided in a range corresponding to the non-release surface portion 2b of the release paper original fabric 2M and the release paper 2 (hereinafter simply referred to as the release paper 2) on the surface of the label base material 3. A non-release surface portion 3b is provided in a range other than the release surface portion 3a on the surface of the label substrate 3. That is, on the surface of the label substrate 3, the release surface portion 3a and the non-release surface portion 3b are arranged in a sea island shape, the release surface portion 3a exists as an island region, and the non-release surface portion 3b is the sea region. Exist as.
Hereinafter, the release surface portion 3a provided on the surface of the label base material 3 is referred to as “base material release surface portion”, and the non-release surface portion 3b provided on the surface of the label base material 3 is referred to as “base material non-release surface”. This is referred to as a mold surface.

Although the planar view shape of the base material release surface part 3a is not particularly limited, it can be formed in the same shape and size as the opening 4 formed in the label base material 3, or a similar shape slightly larger or slightly smaller than that. Preferably, the substrate release surface portion 3 a is formed in a similar shape that is the same size as or larger than the opening 4, and more preferably in a similar shape that is slightly larger than the opening 4. When the substrate release surface portion 3a is smaller than the shape of the opening 4, the adhesive layer of the stretchable film 5 is strongly against the substrate non-release surface portion 3b inside the cut line 6 (corresponding to the periphery of the opening 4). There is a possibility that it is difficult to peel off the hole closing label 1 from the release paper 2 by bonding.
In this case, although the magnitude | size of the base material release surface part 3a can be set suitably, it can form so that the periphery of the base material release surface part 3a may become 0.5 mm-2 mm longer than the periphery of the opening part 4, for example.
In addition, although the planar view shape of the base-material release surface part 3a is not represented in FIG. 1 thru | or FIG. 4, since it represents in drawing of the description column of the manufacturing method mentioned later, please refer to it.

  Similarly to the sheet material 21 constituting the release paper 2, when paper is used as the label substrate 3, it is preferable to provide a sealing layer (not shown) on the surface. In addition, when a sealing layer is provided on the label base material 3, the sealing layer may be provided at least in a range where a release agent is applied. However, in consideration of coating workability, the surface of the label base material 3 It is preferable to form a sealing layer on the whole.

In the illustrated example, a release agent is applied to the formation range of the substrate release surface portion 3 a in the surface of the sheet material 21 to form the release layer 32. Hereinafter, the release layer 32 provided on the surface of the label substrate 3 is referred to as “substrate release layer”.
A conventionally well-known thing can be used for the said mold release agent, and the mold release agent containing silicone resin is mentioned typically.
The surface of the substrate release layer 32 becomes the substrate release surface portion 3a, and the range where the substrate release layer 32 is not provided in the surface of the label substrate 3 becomes the substrate non-release surface portion 3b.
The thickness of the substrate release layer 32 is usually about 0.5 to 3 μm.

A masking layer 33 is provided on the substrate release surface portion 3a. The masking layer 33 is provided so as to cover the entire surface of the substrate release surface portion 3a.
The masking layer 33 is a layer that does not have adhesiveness (adhesiveness) and that weakens the adhesive strength of the adhesive or loses the adhesive strength of the adhesive. The masking layer 33 can be formed, for example, by applying a masking agent on the substrate release surface portion 3a.
Examples of the masking agent include medium ink that does not substantially contain a pigment. This ink is substantially free of pigment, and is water-based, such as an emulsion in which acrylic resin, acrylic copolymer, polyester resin, urethane resin, aqueous polyamide resin, etc. are dispersed in water or water and alcohol. ; Solvents such as toluene, methyl ethyl ketone, ethyl acetate, isopropyl alcohol, rosin, ketone resin, vinyl chloride resin, vinyl chloride-vinyl acetate copolymer, acrylic resin, urethane resin, acrylic-urethane copolymer, polyester resin, etc. Examples include dissolved solvent type; ultraviolet curable type containing curable monomer or oligomer such as acrylic resin; and the like.
The thickness of the masking layer 33 is usually about 0.1 μm to 3 μm.

The stretchable film 5 is laminated on the surface of the label base material 3 via an adhesive layer 58 so as to cover the surface of the masking layer 33. Hereinafter, the pressure-sensitive adhesive layer 58 provided on the back surface of the stretchable film 5 is referred to as a “film pressure-sensitive adhesive layer”.
The stretchable film 5 is formed in the same shape and size as the label substrate 3.
The stretchable film 5 is a film excellent in flexibility and extensibility, and is a film that stretches without being broken when a load is applied from the surface in the normal direction.
The stretchable film 5 can be the same as the stretchable film described in Japanese Patent No. 3490954. For example, a polyurethane film, a rubber or an elastomer film can be used.
Although the thickness of the stretchable film 5 is not specifically limited, For example, they are 20 micrometers-100 micrometers.

The film pressure-sensitive adhesive layer 58 is provided on substantially the entire back surface of the stretchable film 5 by applying a pressure-sensitive adhesive to the back surface of the stretchable film 5. The back surface of the stretchable film 5 is non-releasable, and the surface of the film pressure-sensitive adhesive layer 58 is strongly adhered to the back surface of the stretchable film 5. The film adhesive layer 58 does not usually peel from the stretchable film 5.
The thickness of the film adhesive layer 58 is not specifically limited, For example, they are 5 micrometers-30 micrometers.
The pressure-sensitive adhesive is not particularly limited, and representative examples thereof include a pressure-sensitive pressure-sensitive adhesive and a heat-sensitive pressure-sensitive adhesive.

Furthermore, the label base material 3 is formed with an endless (annular) cut line 6 substantially along the periphery of a range corresponding to the non-release surface portion 2 b of the release paper 2.
The cut line 6 is a line that penetrates the label base material 3 in the thickness direction and divides the label base material 3. The label base material 3 in which the endless cut line 6 is formed in the plane has an inner range of the cut line 6 (a range surrounded by the cut line 6) and an outer range of the cut line 6 (with the cut line 6). It is separable from other than the enclosed range.

The plan view shape of the cut line 6 is the same as the peripheral shape of the opening 4 in plan view. After the label substrate in the area inside the score line 6 is removed, the opening 4 is created.
The cut line 6 may be formed in addition to the label substrate 3 on the condition that the stretchable film 5 and the sheet material 21 of the release paper 2 are not divided.
For example, in the illustrated example, the score line 6 is formed not only on the label base 3 but also on the release layer 22, the base adhesive layer 38, the base release layer 32, and the masking layer 33 of the release paper 2. ing.
The reason why the cut lines 6 are formed in the release layer 22, the substrate release layer 32, and the masking layer 33 of the release paper 2 is that, as described above, the non-release surface portion 2 b of the release paper 2 is the opening 4. And the substrate release surface portion 3a and the masking layer 33 are slightly larger than the shape of the opening 4 (that is, the shape of the cut line 6). It is because it is formed.
However, since the release layer 22, the base adhesive layer 38, the base release layer 32, and the masking layer 33 of the release paper 2 are very thin layers, the cut lines 6 are not formed on them. In addition, the label base material 3 is separated by the cut line 6, and the hole closing label 1 can be easily peeled from the release paper 2.

In the hole closing label 1 having the above layer structure, the back surface of the base adhesive layer 38 facing the release surface portion 2a of the release paper 2 is weakly adhered to the release surface portion 2a, and the release paper 2 is not released. The back surface of the base adhesive layer 38 facing the mold surface portion 2b is strongly bonded to the non-mold release surface portion 2b.
On the other hand, the back surface of the masking layer 33 facing the substrate release surface portion 3a is weakly bonded or non-bonded to the substrate release surface portion 3a. Since the surface of the masking layer 33 is strongly adhered to the film pressure-sensitive adhesive layer 58, the back surface of the film pressure-sensitive adhesive layer 58 facing the base material release surface portion 3 a is connected to the base material release layer via the masking layer 33. It is weakly bonded or non-bonded to the surface portion 3a. Moreover, the back surface of the film adhesive layer 58 facing the base material non-release surface portion 3b is strongly bonded to the base material non-release surface portion 3b.

That is, the label substrate 3 is strongly bonded to the surface of the release paper 2 in the inner area of the cut line 6 and weakly bonded to the surface of the release paper 2 in the outer area of the cut line 6. On the other hand, the stretchable film 5 is weakly adhered or non-adhered to the surface of the label base material 3 in the inner area of the corresponding score line 6 and strong to the surface of the label base material 3 in the outer area of the corresponding score line 6. It is glued.
Note that in this specification, weakly bonded means that the material is detachably bonded (adhered with an adhesive force that can be easily peeled off manually). The term “strongly bonded” refers to being bonded with a stronger adhesive force than in the case of weakly bonding. The difference is, for example, 1.5 times or more, preferably 2 times or more of the adhesive strength in the case of being strongly bonded, compared to the adhesive strength in the case of being weakly bonded. As a preferable specific value, the adhesive strength when weakly bonded is 50 to 500 mN / 50 mm, and the adhesive strength when strongly bonded is 2000 mN / 50 mm or more.
In addition, each said adhesive strength can be measured by the method according to 180 degree | times peeling of JISZ0237.

The hole closing label continuous body 10 and the release paper sticking hole closing label 1 are used as follows.
A part of the periphery of the hole closing label 1 is rolled up and pulled up from the release paper 2 (release paper original 2M). As described above, the label substrate 3 is weakly bonded to the surface of the release paper 2 in the outer area of the cut line 6 and the stretchable film 5 is strongly bonded to the surface of the label substrate 3 in the outer area of the cut line 6. Therefore, at the beginning of lifting, the hole closing label 1 is delaminated between the back surface of the base adhesive layer 38 and the release surface portion 2 a of the release paper 2.
As described above, the label substrate 3 is strongly adhered to the surface of the release paper 2 in the inner area of the cut line 6, and the stretchable film 5 is weakly adhered or not adhered to the surface of the label substrate 3 in the inner area of the cut line 6. Since it is an adhesive, when the cut line 6 is pulled up, the hole closing label 1 is delaminated between the back surface of the film adhesive layer 58 (masking layer 33) and the substrate release surface portion 3a.
Therefore, as shown in FIG. 2B, the hole closing label 1 can be easily peeled from the release paper 2.

Since the hole closing label continuous body 10 and the release paper sticking hole closing label 1 of the present invention are not formed with a hole like the opening 4 in the release paper original fabric 2M and the release paper 2, the hole closing label 1 When the 1 is peeled off, the original release paper 2M and the release paper 2 are not distorted. For this reason, the hole closing label 1 can be peeled off cleanly.
In addition, such a hole-closing label continuous body 10 can prevent wrinkles from being generated in the hole-closing label 1 during storage or transportation because the release paper original 2M is not distorted even when wound on a roll.

  The peeled hole closing label 1 has a stretchable film 5 attached to the surface of a label base 3 having an opening 4 in the surface so as to close the opening 4, and is an annular label in plan view The back surface of the base material adhesive layer 38 provided on the back surface of the base material 3 is exposed (see FIG. 2B).

The hole closing label 1 of the present invention is used by sticking the back surface of the substrate pressure-sensitive adhesive layer 38 to a desired object.
Although the sticking object is not particularly limited, the hole closing label 1 of the present invention is suitable for hole closing use, and therefore, it is preferable to stick the sticking object having holes.
Examples of the adherend having a hole include a cardboard box having a hand hole and a packing box having a hand hole such as a plastic case having a hand hole.

Alignment is performed so that the opening 4 substantially matches the hole of the object to be pasted, and the hole closing label 1 is affixed to the object to be pasted. The hole can be closed.
Since this stretchable film 5 is stretched moderately, the hole can be handed while the hole is closed with the hole closing label 1.

[Continuous Label for Closing Hole and Label for Closing Hole According to Second Embodiment]
The hole closing label continuum 10 and the release paper sticking hole closing label 1 of the second embodiment are not provided with the masking layer 33 shown in the first embodiment.
Briefly, as shown in FIG. 5A, the back surface of the film pressure-sensitive adhesive layer 58 is laminated on the surface of the substrate release surface portion 3a (no masking layer is formed). Other configurations are the same as those in the first embodiment.
The back surface of the film pressure-sensitive adhesive layer 58 is weakly bonded to the surface of the substrate release surface portion 3a, and can be peeled between the back surface of the film pressure-sensitive adhesive layer 58 and the surface of the substrate release surface portion 3a. Separation is also possible between the release surface portion 2a of the release paper original fabric 2M and the back surface of the base adhesive layer 38.
For this reason, when the hole closing label 1 is peeled from the release paper original fabric 2M, the label base material 3 in the inner area of the score line 6 becomes the stretchable film 5 as in FIG. 2B of the first embodiment. Only the label 1 for hole closing can be easily peeled from the release paper while being adhered to the release paper original fabric 2M apart from the release paper.
In the example shown in FIG. 5A, as the adhesive of the film adhesive layer 58, a heat-sensitive adhesive (adhesive that does not exhibit adhesiveness at normal temperature and develops adhesiveness when heated) Is preferably used.

The other hole occluding label continuum 10 of the second embodiment and the hole closing label 1 attached with the release paper are not provided with the substrate release surface portion 3a shown in the first embodiment.
Briefly, as shown in FIG. 5B, film adhesion of the stretchable film 5 (the substrate release surface portion (substrate release layer) is not provided on the surface of the label substrate 3). A masking layer 33 is laminated on the back surface of the agent layer 58. Other configurations are the same as those in the first embodiment.
Since the masking layer 33 weakens the adhesive force of the film adhesive layer 58, the back surface of the film adhesive layer 58 (masking layer 33) in the inner range of the score line 6 is weakly adhered to the surface of the label substrate 3. It is possible to peel between the back surface of the masking layer 33 and the surface of the label substrate 3. For this reason, when the hole closing label 1 is peeled from the release paper original fabric 2M, the label base material 3 in the inner area of the score line 6 becomes the stretchable film 5 as in FIG. 2B of the first embodiment. Only the label 1 for hole closing can be easily peeled from the release paper while being adhered to the release paper original fabric 2M apart from the release paper.
In addition, since the structure of the label 1 for hole obstruction | occlusion of release paper sticking of 2nd Embodiment is the same as that of the continuous body 10 for hole obstruction | occlusion, the illustration is abbreviate | omitted.

[Continuous hole closing label and hole closing label according to the third embodiment]
In the hole closing label continuous body 10 and the release paper sticking hole closing label 1 of the third embodiment, the film adhesive layer 58 shown in the first embodiment has a range corresponding to the inner range of the cut line 6. It is provided except.
Briefly, as shown in FIG. 6, a film adhesive layer 58 is provided on the back surface of the stretchable film 5 except for the range of the back surface of the stretchable film 5 facing the inner range of the score line 6. Yes. In other words, the film pressure-sensitive adhesive layer 58 is provided only on the back surface of the stretchable film 5 facing the outside range of the score line 6.
In the illustrated example, the range where the film pressure-sensitive adhesive layer 58 is not provided and the range corresponding to the inner region of the cut line 6 have the same shape and size, but the range where the film pressure-sensitive adhesive layer 58 is not provided is the cut line. 6 may be a little larger than the range corresponding to the inner region.

In the present embodiment, since the film adhesive layer 58 is not provided in the range facing the inner range of the cut line 6, the surface of the label substrate 3 and the back surface of the stretchable film 5 in the inner range of the cut line 6 are not. It is adhesion, and the label substrate 3 can be peeled from the stretchable film 5 in the inner area of the score line 6.
In the present embodiment, as shown in FIG. 6, it is not necessary to form the substrate release layer 22 and the masking layer 33 of the first embodiment, but this may be provided separately.
In addition, since the structure of the label 1 for hole obstruction | occlusion of release paper sticking of 3rd Embodiment is the same as that of the continuous body 10 for hole obstruction | occlusion, the illustration is abbreviate | omitted.

[Continuous Hole Closure Label and Hole Closure Label According to Fourth Embodiment]
In the fourth embodiment, the continuous hole closing label 10 and the release paper sticking hole closing label 1 are provided with a release paper 2 having a release surface portion 2a, and a substrate adhesive layer 38 on the surface of the release surface portion 2a. A label substrate 3 having an opening 4 in the surface and a stretchable film 5 laminated on the surface of the label substrate 3, and the surface side of the label substrate 3 by the stretchable film 5. The label base material 3 is laminated so that the opening 4 of the label base material 3 is closed and the opening 4 of the label base material 3 is closed from the back side of the label base material 3 by the release paper 2. Has been. The hole closing label 1 corresponds to the label in which the inner range (the range surrounded by the cut line 6) of the cut line 6 shown in the first to third embodiments is removed.

Specifically, as shown in FIG. 7, the hole closing label continuous body 10 can be peeled side by side in the longitudinal direction on the long release paper original fabric 2M and the release paper original fabric 2M. And a plurality of hole closing labels 1 attached to.
The hole closing label 1 has a base material pressure-sensitive adhesive layer 38 on the back surface and a label base material 3 having an opening 4 in the surface, and is laminated and adhered to the surface of the label base material 3. And a stretchable film 5 for closing.
The hole closing label 1 is detachably pasted on the release paper source 2M through the base adhesive layer 38 so as to close the opening 4 of the label base 4.

The base material pressure-sensitive adhesive layer 38 of the label base material 3 is detachably attached to the release surface portion 2a of the release paper original fabric 2M, and the stretchable film 5 is a base material non-release surface portion of the label base material 3. It adheres strongly to 3b.
Moreover, the back surface of the stretchable film 5 corresponding to the opening 4 is not bonded to the release paper original fabric 2M. Therefore, in the opening part 4, the back surface of the stretchable film 5 and the surface of the release paper original fabric 2M are not bonded, and there is a gap between both surfaces.
In FIG. 7, the film pressure-sensitive adhesive layer 58 and the masking layer 33 are provided on the back surface of the stretchable film 5 corresponding to the opening 4, but instead, as in the third embodiment, The film adhesive layer 58 and the masking layer 33 may not be provided on the back surface of the stretchable film 5 corresponding to the opening 4 (not shown).

  In addition, the hole closing label continuous body 10 and the release paper sticking hole closing label 1 of the present invention may appropriately combine or substitute the configurations of the first to fourth embodiments. Various changes may be made to the form.

[First Embodiment of Manufacturing Method of Hole Closure Label Continuum and Hole Closure Label]
Next, a method for producing the hole closing label continuous body 10 and the release paper sticking hole closing label 1 will be described.
Hereinafter, the manufacturing method of the hole closing label continuous body 10 shown in FIGS. 1 and 2 will be described. However, the hole closing label continuous body 10 can be manufactured by other methods.
In the description of the manufacturing method, the description of the same configuration and effect as those described in the column of the hole closing label continuum is omitted, and the terms and symbols may be used as they are.

(Preparation process for release paper stock)
In the preparation process of the release paper original fabric 2M, the release surface portion 2a and the plurality of non-release surface portions 2b are arranged in a sea island shape, the release surface portion 2a is a sea region, and the non-release surface portion 2b is an island region. This is a step of preparing a long release paper original fabric 2M having a surface to be processed.

Since the length of the original release paper 2M and the sheet material 21 thereof have been described in the above-described hole closing label continuous body 10, they are omitted.
The method of providing the non-release surface portion 2b and the release surface portion 2a on the surface of the release paper original fabric 2M is not particularly limited, and an appropriate method can be adopted.
For example, when the entire surface of the sheet material 21 to be used has non-release properties, a release treatment (for example, a release agent) is performed on the surface of the sheet material 21 except for the formation range of the non-release surface portion 2b. By performing coating, a release paper original fabric 2M in which the release surface portion 2a and the non-release surface portion 2b are arranged in a sea-island shape can be obtained.
Further, when the entire surface of the sheet material 21 to be used has releasability, the surface of the surface of the sheet material 21 is a surface for enhancing the adhesiveness to the pressure sensitive adhesive within the formation range of the non-release surface portion 2b. By performing the treatment, it is possible to obtain a release paper original fabric 2M in which the release surface portion 2a and the non-release surface portion 2b are arranged in a sea island shape.

The former method is preferable because it is easy to form.
As shown in FIGS. 8 and 9, a release agent is applied to the surface of the sheet material 21 constituting the release paper original fabric 2M to form a release layer 22. In FIG. 8, the range where the release agent is applied is indicated by light ink painting.
The release agent is applied outside the planned formation range of the non-release surface portion 2b.
The surface of the sheet material 21 is exposed in a range where the release agent is not applied, and this becomes the non-release surface portion 2b. As described above, the shape of the non-release surface portion 2b in plan view is preferably formed in a similar shape that is the same shape as or slightly smaller than the opening portion 4, and as shown in FIGS. It is more preferable to form a similar shape slightly smaller than the opening 4.
For example, the planar view shape of the non-release surface portion 2b is a substantially rectangular shape that is slightly smaller than the opening 4 to be formed.

  In the illustrated example, two rows of hole closing labels 1 are manufactured in the width direction of the release paper original fabric 2M. However, the manufacturing method of the present invention uses the hole closing labels 1 as the release paper original. The present invention can be similarly applied to the case where only one row is formed in the anti-2M width direction, or when three or more rows are formed.

(Lamination process of the label base material)
In the step of laminating the label base material 3M, the label base material 3M provided with the base material pressure-sensitive adhesive layer 38 on the back surface is placed on the surface of the release paper raw material 2M through the base material pressure-sensitive adhesive layer 38. It is a process of sticking. In this laminating step, a release paper raw fabric provided with a base adhesive layer on the surface on which the release surface portion and the non-release surface portion are formed is used, and the base adhesive layer of the release paper original fabric is used. The back surface of the label base material (not provided with a base material pressure-sensitive adhesive layer) may be attached to the surface (not shown).
As the label base material 3M, an elongated one having a width substantially equal to that of the release paper base 2M is used.
A base material pressure-sensitive adhesive layer 38 is provided in a solid shape on the entire back surface of the label base material 3M. In addition, a commercial item can also be used for such label base material original fabric 3M with an adhesive.

The label base material 3M is overlapped with the base adhesive layer 38 facing the surface of the release paper base 2M (see FIGS. 10 and 11).
If necessary, pressure is applied with a roller from the surface of the label base material 3M, and the base pressure-sensitive adhesive layer 38 is sufficiently adhered to the surface of the release paper base 2M.

(Formation process of base material non-release surface part and base material release surface part)
This forming step is a step of forming the substrate release surface portion 3a in a range corresponding to each non-release surface portion 2b of the release paper original fabric 2M in the surface of the label substrate original fabric 3M.
The method of providing the base material non-release surface portion 3b and the base material release surface portion 3a on the surface of the label base material raw material 3M laminated on the surface of the release paper raw material 2M is not particularly limited, and an appropriate method is used. Can be adopted.

For example, in the case where the entire surface of the sheet constituting the label base material 3M has non-release properties, a release treatment (for example, release) is performed on the surface, except for the formation range of the base non-release surface portion 3b. By applying a mold, a label base material 3M in which the base release surface portion 3a and the base non-release surface portion 3b are arranged in a sea island shape can be obtained.
Moreover, when the whole surface of the sheet | seat which comprises label base material original fabric 3M has mold release property, the adhesiveness with an adhesive is improved in the formation range of the base material non-mold release surface part 3b among the surfaces. By performing the surface treatment for this, a label base material 3M in which the base part release surface part 3a and the base non-release part 3b are arranged in a sea-island shape can be obtained.

The former method is preferable because it is easy to form.
As shown in FIG.12 and FIG.13, a mold release agent is applied to the surface of the sheet | seat 31 which comprises the label base material original fabric 3M, and the base material release layer 32 is formed. In FIG. 12, the range where the release agent is applied is indicated by light ink painting.
The release agent is applied outside the planned formation range of the base non-release surface portion 3b.
The surface of the sheet 31 is exposed in a range where the release agent is not applied, and this becomes the substrate non-release surface portion 3b. As described above, the plan view shape of the substrate release surface portion 3a is preferably formed in a similar shape that is the same size as or slightly larger than the opening portion 4, and as shown in FIGS. It is more preferable to form a similar shape slightly larger than the opening 4.
For example, the planar view shape of the substrate release surface portion 3 a is a substantially rectangular shape that is slightly larger than the opening 4.

If necessary, a masking agent 33 is applied over the surface of the substrate release surface portion 3a to form a masking layer 33 (see FIG. 14).
The release agent and the masking agent can be applied by a known printing method.

(Cutting line forming process)
The formation process of the score line 6 is substantially performed on the periphery of the range corresponding to each non-release surface portion 2b of the release paper original fabric 2M in the plane of the label base material original 3M attached to the surface of the release paper original fabric 2M. It is a step of forming an endless cut line 6 along.
As shown in FIGS. 15 and 16, a cutting tool 91 such as a punching blade is pressed from the surface side of the label base material 3M to form an endless cut line 6 in the surface of the label base material 3M. To do. The cut line 6 is formed in the peripheral shape of the opening 4 to be formed. The incision line 6 is formed between the peripheral edges of the release paper 2 regardless of the peripheral edge of the non-release surface portion 2b and the peripheral edge of the substrate release surface portion 3a.
The cut line 6 may be formed at least on the label base material 3M. However, when the cut lines 6 are formed after the substrate release layer 32 and the masking layer 33 are formed, the cut lines 6 are simultaneously formed in these layers (see FIG. 16).
Further, when the cut line 6 is formed, it is necessary not to press the cutting tool 91 until the release paper original fabric 2M is divided in the thickness direction. However, the surface of the release paper original fabric 2M has a substantially V-shaped cross section. The cutting tool 91 may be pressed until the notch is formed.

In addition, although the lamination | stacking process of the label base material raw fabric 3M, the formation process of the base material non-release surface part 3b and the base material release surface part 3a, and the formation process of the score line 6 are normally performed in said order. If necessary, the execution order of these steps can be changed.
For example, after the formation process of the base material non-release surface part 3b and the base material release surface part 3a, the lamination process of the label base material 3M may be performed, and then the formation process of the score line 6 may be performed. That is, the label base material raw material 3M in which the base material non-release surface portion 3b and the base material release surface portion 3a are formed is prepared, and the base material release surface portion 3a corresponds to the non-release surface portion 2b of the release paper raw material 2M. As described above, the label base material 3M may be laminated on the surface of the release paper base 2M while being aligned, and then the score line 6 may be formed.

Moreover, the formation process of the cut line 6 may be performed after the lamination process of the label base material 3M, and then the formation process of the base non-release surface portion 3b and the base release surface portion 3a may be performed. That is, after the label base material 3M is laminated on the surface of the release paper base 2M, the cut line 6 is formed corresponding to the non-release surface portion 2b, and the label base material corresponding to the cut line 6 is formed. The substrate release surface portion 3a may be formed on the anti-3M surface. In this case, the score line 6 is not formed in the substrate release layer 32, but the substrate release layer 32 is a thin layer and thus does not hinder the peeling of the hole closing label 1.
However, when a release agent or the like is applied to the label base material 3M after the cut line 6 is formed, a part of the label base material 3M may fall from the release paper base 2M. 6 is preferably formed on the label base material 3M on which the base non-release surface portion 3b and the base release surface portion 3a are already formed.

(Lamination process of stretchable film)
In the lamination step of the stretchable film original fabric 5M, the stretchable film original fabric 5M provided with the film adhesive layer 58 on the back surface is pasted on the surface of the label base material 3M via the film adhesive layer 58. It is a process to do. In this laminating step, the label base material having a film pressure-sensitive adhesive layer on the surface on which the base material release surface portion and the base material non-release surface portion are formed is used. You may stick the back surface of the stretchable film original fabric (the film adhesive layer is not provided) on the surface (not shown).
As the stretchable film original fabric 5M, an elongated one having a width substantially equal to that of the label substrate original fabric 3M is used.
A film pressure-sensitive adhesive layer 58 is provided in a solid form on the entire back surface of the stretchable film original fabric 5M. In addition, a commercial item can also be used for such a stretchable film original fabric 5M with an adhesive.

The stretchable film original fabric 5M is overlapped with the film pressure-sensitive adhesive layer 58 facing the surface of the label base material original fabric 3M (see FIGS. 17 and 18).
If necessary, the film pressure-sensitive adhesive layer 58 is sufficiently adhered to the surface of the label base material 3M by pressing with a roller from the surface of the stretchable film original 5M.

(Shaping process of hole closing label)
The shaping process of the hole closing label 1 includes the label base material 3M and the stretchable film substantially along the periphery of a range corresponding to a range including one non-release surface portion 2b and the surrounding release surface portion 2a. This is a step of forming a cut line 7 for cutting the original fabric 5M in the thickness direction and removing an outer range of the cut line 7.
As shown in FIGS. 19 and 20, in order to shape the outer shape of the hole closing label 1, a cutting tool 92 such as a punching blade is pressed from the surface side of the stretchable film original fabric 5M, and the stretchable film original fabric is Endless cut lines 7 are formed in the plane of 5M and the label base material 3M. The cut line 7 is formed substantially along the periphery of a range corresponding to a range including one non-release surface portion 2b of the release paper original fabric 2M and the surrounding release surface portion 2a. That is, the cut line 7 is formed in the peripheral shape of the hole closing label 1 to be formed. For example, the plan view shape of the cut line 7 is substantially rectangular.

Finally, by removing the outer area (unnecessary portion A, shown by the shaded portion in FIG. 19) of the cut line 7 from the stretchable film original fabric 5M and the label base material original fabric 3M, FIG. 1 and FIG. As shown in FIG. 1, a continuous hole closing label 10 is obtained.
Further, by forming the incision line 7 not only on the stretchable film original fabric 5M and the label base material original fabric 3M but also on the release paper original fabric 2M at the same time, the release paper sticking as shown in FIGS. The hole closing label 1 is obtained.

  In addition, in the formation process of the base material non-release surface part 3b and the base material release surface part 3a of the said manufacturing method, the masking layer 33 does not need to be formed. When the masking layer 33 is not formed, the hole closing label continuous body 10 and the release paper sticking hole closing label 1 as shown in FIG. 5A of the second embodiment are obtained.

Further, in the laminating step of the stretchable film original fabric 5M of the above manufacturing method, the film adhesive layer 58 is not provided in the range corresponding to the inner range of the score line 6 and corresponds to the inner range of the score line 6. In addition to the range, a stretchable film original fabric 5M provided with a film pressure-sensitive adhesive layer 58 may be used. When such a stretchable film original fabric 5M is used, the release surface portion 2a and the masking layer 33 may or may not be provided on the surface of the label substrate original fabric 3M.
In the case of this manufacturing method, the hole closing label continuous body 10 as shown in FIG. 6 of the third embodiment and the hole closing label 1 attached with the release paper are obtained.

[Second Embodiment of Manufacturing Method of Hole Closure Label Continuum and Hole Closure Label]
2nd Embodiment of a manufacturing method is one of the methods of manufacturing the label continuous body 10 for hole obstruction | occlusion which concerns on 4th Embodiment as shown in FIG. But the hole obstruction | occlusion label continuous body 10 which concerns on 4th Embodiment cannot be manufactured only with this manufacturing method.
Of the second embodiment of the manufacturing method, a release paper original fabric preparation step, a label base material stacking step, a base non-release surface portion and a base release surface portion forming step, a score line forming step and stretching The process up to the lamination process of the original film is the same as that in the first embodiment, and the description thereof is omitted.

(Peeling process)
In 2nd Embodiment, a laminated body as shown in FIG.17 and FIG.18 is obtained by performing to the lamination process of an extensible film original fabric.
In this laminate, the label base material 3M and the stretchable film material 5M are peeled from the release paper base 2M.
The stretchable film original fabric 5M is strongly bonded to the label substrate original fabric 3M at the substrate non-release surface portion 3b and weakly bonded or non-adhered to the label substrate original fabric 3M at the substrate release surface portion 3a. Further, a cut line 6 is formed in the label base material 3M.
For this reason, when the label base material 3M and the stretchable film base 5M are peeled off, the inner region of the score line 6 of the label base material 3M remains adhered to the surface of the release paper base 2M. The label base material 3M and the stretchable film material 5M are peeled from the release paper material 2M (see FIG. 21).
Since the inner region of the score line 6 is removed at the time of peeling, the opening 4 is formed in the peeled label base material 3M.

(Lamination process on the release paper stock)
The laminate of the label base material 3M and the stretchable film material 5M is laminated on the surface of the release paper 2M ′ separate from the release paper 2M (see FIG. 22).
A release layer 29 is provided on the entire surface of the separate release paper sheet 2M ′. Therefore, a laminate of the label base material 3M and the stretchable film base 5M is laminated on the surface of the separate release paper base 2M ′ via the base adhesive layer 38.

(Shaping process of hole closing label)
Finally, the hole closing label 1 is shaped as in the first embodiment of the manufacturing method.
Specifically, as shown in FIG. 23, in order to shape the outer shape of the hole closing label 1, a cutting tool 92 such as a punching blade is pressed from the surface side of the stretchable film original fabric 5M, and the stretchable film Endless cut lines 7 are formed in the surfaces of the original 5M and the label base 3M. This incision line 7 is larger than one opening 4 of the release paper original fabric 2M and surrounds the outside of the opening 4 (one non-release surface portion 2b of the first embodiment and the surrounding release) (Same as the range corresponding to the range including the surface portion 2a). That is, the cut line 7 is formed in the peripheral shape of the hole closing label 1 to be formed. For example, the plan view shape of the cut line 7 is substantially rectangular.

  Finally, as in the first embodiment of the manufacturing method, by removing the outer area of the cut line 7 from the stretchable film original fabric 5M and the label base material original fabric 3M, holes as shown in FIG. The continuous label body 10 for closure is obtained.
