Description

  The present invention relates to an adhesive tape or sheet, and a paper diaper, and more specifically, an adhesive tape or sheet folded in a form that can be easily developed without peeling off from an attached article, and the adhesive tape Or it is related with the paper diaper which a sheet | seat is provided and can hold | maintain the rounded state easily when discarding.

  A paper diaper (particularly a pants-type paper diaper) is provided with a constraining adhesive tape or sheet for holding it in a rolled state when discarded. As such an adhesive tape or sheet for restraint, conventionally, the free end portion is a fastening portion used when discarding the diaper, and the fastening portion is positioned beyond the opening edge of the waist portion when extended. And has a length to be obtained, and is folded in a three-fold state composed of three layers of a region including a fixing portion, a region including the fastening portion, and an intermediate region connecting both the regions (see Patent Document 1) The tape-like support provided with a fixing portion for fixing to the adherend surface on the surface of one of the end portions is folded in half so that the fixing portion is located on the outer side, and the two-folded There has been proposed a structure in which the above support is folded or wound at least once in the same direction sequentially from the fold side (see Patent Document 2).

No. 8-10305 Japanese Patent Laid-Open No. 9-272845

  However, in the conventional folded adhesive tape or sheet used for pants-type paper diapers, in the folded state, the adhesiveness between the supports is low and a space is created, and therefore, floating occurs. Further, the restraining adhesive tape or sheet is in a form in which both end portions are directed in the same direction, and one end portion protrudes from the other end portion, and a knob portion is formed at one end portion. It has a configuration that is folded by folding it three times or more in the form of a bellows, and is long in the direction of the end portion that does not protrude from the fold portion at the end portion side that does not protrude by pulling the knob portion. When having a configuration that can be deployed in a scale shape, when the knob portion is pulled and deployed in a long shape in the direction of the end portion that does not protrude from the fold portion in the portion on the end portion side that does not protrude In addition, a peeling force (especially a peeling force on the side of the crease portion) is generated between the part that is attached to the paper diaper in the folded form and the paper diaper. Tape or paper Door there is a case where peeled off from disposable diapers, disposable diapers will be damaged.

  Moreover, the thickness may be thick and the flexibility may not be sufficient. In particular, there is a demand for a material that can be more easily developed into a long shape.

  Furthermore, since the disposable diaper is discarded after use (that is, it is a disposable type), from the viewpoint of reducing the amount of garbage, the disposable diaper can be made more compact and small and rounded. Paper diapers are required.

Accordingly, an object of the present invention is to provide a pressure-sensitive adhesive tape that is folded in a form that does not float when folded, and that can be easily developed into a long shape without peeling off from the attached article. To provide a sheet.
Another object of the present invention is to provide an adhesive tape or sheet that can be suitably used as a constraining adhesive tape or sheet for holding a paper diaper in a rolled state.
Still another object of the present invention is to provide a disposable diaper that can easily maintain a rolled state when discarded.
Another object of the present invention is to provide a disposable diaper that can further reduce the rounded state when discarded.

  As a result of intensive studies to solve the above problems, the present inventors have found that the adhesive tape or sheet is in a form in which both ends are directed in the same direction and one end protrudes from the other end. The end portion is not protruded by pulling the knob portion in a form in which the knob portion is formed at one end portion and is folded by folding the bellows shape three times or more. Even when the adhesive tape or sheet is folded in a specific configuration, even when it has a configuration that can be expanded in a long shape in the direction of the end portion that does not protrude from the crease portion in the part of It has been found that it can be easily developed into a long shape without being lifted, and without being peeled off from the attached article. Moreover, when the adhesive tape or sheet | seat folded in such a form was mounted | worn with a paper diaper, it discovered that the state rolled up when discarding a paper diaper could be hold | maintained easily. The present invention has been completed based on these findings.

That is, in the present invention, an adhesive layer, a temporary adhesive layer, a release treatment layer are formed at predetermined sites on both surfaces of the long support, and both ends are directed in the same direction. One end part protrudes from the other end part, and in a form in which a knob part is formed on one end part, it has a configuration that is folded by folding it into a bellows shape three or more times, By pulling the knob portion, an adhesive tape or sheet that can be elongated in the direction of the end portion that does not protrude from the crease portion in the end portion side portion that does not protrude, the following (a It is an adhesive tape or sheet characterized by having the structure of () to (d).

[Adhesive tape or sheet]
FIG. 1 is a schematic sectional view showing an example of the pressure-sensitive adhesive tape or sheet of the present invention. In FIG. 1, 1 is an adhesive tape or sheet (sometimes referred to as "adhesive tape"), 1a is an end that does not protrude (sometimes referred to as a "non-projecting end"), and 1b is an end that protrudes ( 1c may be referred to as a fold portion on the non-projecting end portion 1a side when folded in a W shape and folded three times (may be referred to as a "non-projecting end portion fold portion"). 1d is an intermediate fold when folded in a W-shape three times (sometimes referred to as “intermediate fold portion”), and 1e is folded in a W-shape three times and folded. A fold portion on the protruding end portion 1b side (sometimes referred to as a “protruding end portion side fold portion”), 2 is a support body, and 2a is a non-projecting end portion side portion of the support body 2 (referred to as a “sticking portion”). 2b is a part on the protruding end side of the support 2 (referred to as "deployment part") 2c is a portion between the folds facing the portion 2a on the end portion side of the support 2 where the support 2 does not protrude (sometimes referred to as “paste-side intermediate portion”), and 2d is the support 2 The part between the creases facing the part 2b on the protruding end side (may be referred to as “deployment-side intermediate part”), 3a1 may be referred to as an adhesive layer (“sticking adhesive layer”) 3a2 is a release treatment layer (sometimes referred to as "release treatment layer for fixed adhesive layer"), 3b1 is an adhesive layer (sometimes referred to as "development adhesive layer"), and 3b2 is release Treatment layer (sometimes referred to as “release treatment layer for adhesive pressure-sensitive adhesive layer”), 3b3 represents a printing layer (sometimes referred to as “printing layer for knob part”), 3c1 represents an adhesive layer (“fixed pressure-sensitive adhesive”) 3c2 may be referred to as a temporary adhesive layer (sometimes referred to as a "first temporary adhesive layer"). 3d1 is a temporary adhesive layer (sometimes referred to as "second temporary adhesive layer"), 3d2 is a release treatment layer (sometimes referred to as "development treatment layer for developed adhesive layer"), 4 is A knob part, 5a is a peelable part, and 5b is an adhesion part.

  Specifically, in the pressure-sensitive adhesive tape 1, the support 2 is a long sheet having a configuration in which the sticking part 2a, the sticking side intermediate part 2c, the development side intermediate part 2d, and the development part 2b are arranged in series in this order. However, the three folds of the non-projecting end fold portion 1c, the intermediate fold portion 1d, and the projecting end portion fold portion 1e are arranged so that the end portion of the development portion 2b protrudes from the end portion of the sticking portion 2a. It has a configuration in which it is folded into three W-shapes by being folded into a bellows shape or an accordion shape (the shape of the accordion stretchable portion) at the portion. In addition, the boundary part of the sticking part 2a and the sticking side intermediate part 2c is the non-projecting end part side fold part 1c, and the boundary part of the sticking side intermediate part 2c and the development side intermediate part 2d is the intermediate crease part 1d. A boundary portion between 2d and the development site 2b is a protruding end side fold portion 1e. The part located at the end of the development part 2 b is a knob part 4. Moreover, the site | part of the non-protruding end part 1a side of the sticking site | part 2a and the sticking side intermediate part 2c is the peelable part 5a, On the other hand, the non-protruding end part side crease part of the sticking part 2a and the sticking side intermediate part 2c The part on the 1c side is an adhesion part 5b. Furthermore, in the sticking part 2a, a sticking pressure-sensitive adhesive layer 3a1 for sticking to an article is formed on the surface side, and the face on the sticking side intermediate part 2c side (the face on the inner face side) A fixed pressure-sensitive adhesive layer release treatment layer 3a2 for partly bonding to the fixed pressure-sensitive adhesive layer 3c1 is partially formed (to the peelable portion 5a) only (on the end portion side that does not protrude). In the affixing side intermediate part 2c, a fixed adhesive layer 3c1 is formed on the surface of the affixing part 2a side, and the development side intermediate part 2d is detachably bonded to the development side intermediate part 2d side. One temporary adhesive layer 3c2 is formed. In the development-side intermediate part 2d, a second temporary adhesive layer 3d1 is formed on the surface on the application-side intermediate part 2c side so as to be peelable from the application-side intermediate part 2c. A developed pressure-sensitive adhesive layer release treatment layer 3d2 for releasably bonding to the pressure-sensitive adhesive layer 3b1 is formed. In the development part 2b, a development pressure-sensitive adhesive layer 3b1 for application to an article is formed on the surface on the development side intermediate part 2d side, and a release treatment layer 3b2 for adhesion pressure-sensitive adhesive layer is formed on the outer surface side. Further, a knob portion printing layer 3b3 is formed at a portion located in the knob portion 4.

  Therefore, the pasting site 2a and the pasting side intermediate site 2c are not peeled off at the bonding site 5b, but are pasted together so as to be partially peelable only at the peelable site 5a. The intermediate portion 2d is bonded so that it can be peeled off entirely, and the pasting side intermediate portion 2c and the development-side intermediate portion 2d are temporarily attached so that they can be peeled off entirely. . That is, as the pressure-sensitive adhesive tape 1, the surfaces of the portions 2 a to 2 d of the support 2 facing each other are bonded so as to be peelable except that they are stuck so as not to be peeled off at the bonding portion 5 b. Yes. Therefore, the adhesive tape 1 can be developed in a long shape in the direction from the non-projecting end side fold portion 1c to the non-projecting end portion at the application site by pulling the knob portion 4. For example, in a state where the adhesive tape 1 in a folded state is applied to an article using the adhesive layer 3a1 of the application site 2a (at this time, the application site 2a is fixed to the product by application), the knob The interface between which the portions 2a to 2d can be peeled by pulling the portion 4 in the direction from the protruding end portion fold portion 1e toward the protruding end portion 1b or the knob portion 4 (that is, in the left direction in FIG. 1). Peeling occurs at (the interface other than the adhesion site 5b), and the film can be developed into a long shape. At this time, even if the knob portion 4 is pulled strongly, it can be easily developed into a long shape without causing separation from the attached article. This is because the pasting part 2a and the pasting side intermediate part 2c are pasted together so that they cannot be peeled off at the adhesive part 5b (part on the non-projecting end part side fold part 1c side). This seems to be because the shearing force at the bonding part 5b between the sticking part 2a and the sticking side intermediate part 2c is generated, and the peeling force to the article at the sticking part 2a is not generated.

  The length (or width) of the release treatment layer for the fixed pressure-sensitive adhesive layer is 10 with respect to the entire length of the end portion side (sticking portion) where the support does not protrude from the end portion that does not protrude toward the crease portion. It is desirable to be in the range of -90% (preferably 50-90%, more preferably 70-90%). That is, 10% to 90% (preferably 50% to 90%) of the total length of the applied part from the end part that does not protrude toward the crease part on the surface on the protruding end part side (deployment part) side. Further, it is desirable that the release treatment layer is formed in a range of 70 to 90%. In addition, when the length of the release treatment layer for the fixed adhesive layer is 10% or less with respect to the entire length of the application site, the tape is applied when the tape is unfolded during use (each part is peeled open). There is a tendency that the crease between the part 2a and the application-side intermediate part 2c tends to be broken, and the adhesive layer is peeled off from the adherend when the length is 90% or more of the entire application part. Or the adherend may be destroyed.

  In addition, when the pasting part 2a and the pasting side intermediate part 2c are pasted together so that they can be completely peeled, the direction of the knob part 4 from the projecting end part side fold part 1e to the projecting end part 1b or the knob part 4 If it is pulled strongly, the pasting part 2a is pulled on the non-projecting end part side crease part 1c side, and a peeling force is generated between the pasting part and the article, whereby peeling of the adhesive tape or sheet from the article, Damage will occur.

  Since FIG. 1 and the like are illustrated so that the layer configuration is clear, the non-projecting end side fold portion 1c, the intermediate fold portion 1d, and the projecting end portion fold portion 1e have a width in the thickness direction. Yes, it is expressed in a form that is folded in two places at the top and bottom of the width, but in reality, depending on the method of folding, it is folded into a U-shape and a form folded into a V-shape. It becomes the form folded in various forms. In addition, the fixed adhesive layer 3c1 is illustrated so as to clarify the adhesion state between the application site 2a and the application-side intermediate site 2c, and thus is not illustrated in a form having a certain thickness. It has the thickness of.

  The pressure-sensitive adhesive tape or sheet of the present invention (sometimes referred to as a “foldable pressure-sensitive adhesive tape or sheet”) has both ends facing in the same direction as shown in FIG. 2 and may be configured to be folded by bending it three times in a W shape in a form in which the knob portion is formed at one end portion. As shown in the figure, both end portions are directed in the same direction, and one end portion protrudes from the other end portion, and a knob portion is formed at one end portion. Or you may have the structure folded by bending in accordion form (shape of the expansion-contraction site | part of an accordion) 5 times or more.

  FIG. 2 is a schematic cross-sectional view showing another example of the pressure-sensitive adhesive tape or sheet of the present invention. FIG. 2 (a) shows that both ends are oriented in the same direction and one end is the other end. FIG. 2 (b) shows an example of a configuration in which the knob portion is formed by being bent five times in a bellows shape or an accordion shape in a form in which the knob portion is formed at one end portion in a more protruding state. Both ends are oriented in the same direction, and one end protrudes from the other end, and a knob is formed at one end. The bellows or accordion 7 The example of the structure folded by folding is shown. In FIG. 2, 2e is an intermediate part between the sticking part 2a of the support 2 and the development part 2b, 3e1 is a temporary adhesive layer, 3e2 is a temporary adhesive layer, 3f1 is a temporary adhesive layer, and 3f2 is a temporary adhesive layer. Adhesive layer, 3g1 is a temporary adhesive layer, 3g2 is a temporary adhesive layer, 3h1 is a temporary adhesive layer, 3h2 is a temporary adhesive layer, 1a to 1e, 2, 2a, 2b, 3a1, 3a2, 3b1, Reference numerals of 3b2, 3b3, 3c1, 3c2, 3d1, 3d2, 4, 5a, 5b and the like are the same as described above.

  Thus, the foldable adhesive tape or sheet of the present invention is “the two ends are oriented in the same direction and one end protrudes from the other end, and is pinched on one end. In a form in which the portion is formed, it can have a configuration that is folded by folding it three times or more in a bellows shape or an accordion shape. As described above, the number of times of folding when “folding into a bellows shape or an accordion shape three times or more” is not particularly limited, and the purpose of use, the length when folded, and the length when expanded into a long shape are not limited. The thickness can be appropriately selected depending on the thickness when folded. For example, as shown below, when a foldable adhesive tape or sheet is used as an adhesive tape or sheet for constraining a paper diaper, the number of times of folding when “folding into a bellows shape or an accordion shape three times or more” is W-shaped. However, it may of course be 5 times or more (for example, 5 times or 7 times).

  Further, in the foldable adhesive tape or sheet, “one end protrudes from the other end, and a knob is formed at one end, three times in a bellows shape or an accordion shape”. As a configuration that is folded by the above-described folding, it is sufficient that the end portion protrudes from the other end portion as a result of the folding, so that the knob portion is formed. As a result of folding with the end portion protruding from the other end portion, one end portion may protrude from the other end portion, and one end portion is nearer to the other end portion. As a result of being folded in a state of being located at a position, one end may protrude from the other end.

That is, the foldable pressure-sensitive adhesive tape or sheet of the present invention has a pressure-sensitive adhesive layer, a temporary adhesive layer, and a release treatment layer formed at predetermined sites on both surfaces of a long support, and the both ends are the same. In the form where one end part protrudes from the other end part and a knob part is formed on one end part, it is folded by folding it into a bellows shape three times or more. With an adhesive tape or sheet that has a configuration and can be expanded in the direction of the end that does not protrude from the crease portion at the end portion side that does not protrude by pulling the knob portion And it has the structure of following (a)-(d).
(A) The structure which has the adhesive layer for affixing on articles | goods on the surface of the site | part of the edge part (sticking site | part) which does not protrude of a support body (b) The site | part (deployment site | part) which protruded in the sticking site | part ) Side surface (inner surface side) has a release treatment layer only partially on the end side, and has an adhesive layer on the surface on the application site side facing the application site. And a configuration in which the part to be applied and the part facing the part to be applied are partly peeled together (c) on the surface on the side of the application site (surface on the inner surface side) in the development site, The structure which has an adhesive layer, and the expansion | deployment site | part and the site | part facing with respect to a deployment site | part were bonded together by the mold release process layer so that peeling was possible. The parts of these are temporarily attached to each other by a temporary adhesive layer.

As the foldable adhesive tape or sheet, as shown in FIG. 1, an adhesive layer, a temporary adhesive layer, a release treatment layer are formed at predetermined sites on both surfaces of the long support, and Both ends are oriented in the same direction, and one end protrudes from the other end, and a knob is formed at one end, and is bent three times in a W shape. By pulling the knob part, it is possible to develop it in a long shape in the direction of the end part that does not protrude from the crease part in the part on the end part side that does not protrude. Furthermore, it is preferable to have the following configurations (a1) to (d1).
(A1) Configuration having a pressure-sensitive adhesive layer (sticking pressure-sensitive adhesive layer) for sticking to an article on the surface of an end-side part (sticking part) where the support does not protrude (b1) A protruding end part at the sticking part On the side part (deployment part) side surface (inner surface side surface), there is a partly release treatment layer (release treatment layer for fixed adhesive layer) only on the end side, There is a pressure-sensitive adhesive layer (fixed pressure-sensitive adhesive layer) on the surface on the side of the application site in the internal site (applied side intermediate site) when folded into an opposing W-shape, and the application site and the application side intermediate (C1) having a pressure-sensitive adhesive layer (deployed pressure-sensitive adhesive layer) on the surface of the application site (surface on the inner surface side) in the development site, and the development site And the inner part when folded in a W-shape facing the development part (middle of the development side (D1) A part on the inner side when the support is folded into a W-shape (affixing side) A structure in which the intermediate portion and the development-side intermediate portion are temporarily attached to each other by a temporary adhesive layer (first temporary adhesive layer and second temporary adhesive layer).

  When the folding pressure-sensitive adhesive tape or sheet of the present invention is elongated, peeling occurs at the interface between the parts (for example, the interface between the parts 2a to 2d in the pressure-sensitive adhesive tape 1 shown in FIG. 1). The order of occurrence is not particularly limited. For example, when the adhesive tape 1 shown in FIG. 1 is elongated, (1) the interface between the application site 2a and the application-side intermediate region 2c, and the interface between the application-side intermediate region 2c and the development-side intermediate region 2d, After peeling occurs at any one of the interfaces between the development-side intermediate part 2d and the development part 2b, after peeling occurs at any one of the interfaces that have not yet peeled, the other Peeling may occur at the interface of (2) the interface between the application site 2a and the application-side intermediate site 2c, the interface between the application-side intermediate region 2c and the development-side intermediate region 2d, and the development-side intermediate region 2d and the development site 2b. After peeling occurs in parallel at any two of the interfaces, the peeling may occur at the remaining interface. (3) The interface between the application site 2a and the application-side intermediate site 2c, and application Side intermediate part 2c And the interface between the fine expanded side intermediate portion 2d, peeled in parallel with three interfaces of the interface between the interface of the expansion-side intermediate portion 2d and the deployment site 2b may occur.

  In particular, from the viewpoint of easy deployment operation, the adhesive tape 1 is peeled off at the interface between the deployment site 2b and the deployment-side intermediate site 2d, and then at the interface between the deployment-side intermediate site 2d and the application-side intermediate site 2c. It is preferable to have a form in which peeling occurs and then develops so that peeling occurs at the interface between the application-side intermediate part 2c and the application part 2a. Thus, in the present invention, as the folding adhesive tape or sheet, the part on the end side where the support does not protrude and the part facing the part on the end side where the support does not protrude After peeling occurred at the interface with the substrate, separation occurred at the interface between the non-projecting end side portion of the support and the protruding end portion portion, and then the support protruded. It is preferable to have a form that develops so that peeling occurs at the interface between the end portion and the portion facing the protruding end portion of the support.

Therefore, in the present invention, the opposing surface in the peelable part between the part on the end side where the support does not protrude and the part facing the part on the end side where the support does not protrude The separation force between the two is F ^1, and the support is opposed to the part between the non-projecting end part and the projecting end part when folded in a bellows shape. the peel force between the surfaces each other that, from the site side of the protruding non end side of the support, F ²¹ ~F ²ⁿ (n is a part of an end side which does not protrude the support, projecting end The number of combinations of surfaces facing each other in the portion between the two portions), and the surface of the protruding end portion of the support and the protruding end portion of the support the peel force between the surface of the portion facing against upon the F ^3, F ^1, It is preferred ^{that 2} and F ³ satisfies the following relationship (1).
F ³ <F ^{21 to} F ²ⁿ <F ¹ (1)

The relations of the sizes of F ^{21 to} F ²ⁿ are not particularly limited, and all of them may have the same size, and partially have the same size. It may be a relationship having the same, or a relationship having different sizes. Note that “F ^{21 to} F ²ⁿ ” may be collectively referred to as “F ² ”.

Thus, as F ¹ , F ² , and F ³ , the magnitude of each peeling force is not particularly limited as long as the relational expression (1) is satisfied, but from the viewpoint of facilitating the unfolding operation, etc. the F ^3, for example, it is desirable 0.1~1.5N / 25mm (preferably 0.2~1.2N / 25mm, more preferably 0.3~1.0N / 25mm) is. The F ^2, for example, it is desirable 0.5~5.0N / 25mm (preferably 1.0~3.5N / 25mm, more preferably 1.5~3.0N / 25mm) is. The F ^1, for example, it is desirable 0.7~6.0N / 25mm (preferably 1.5~4.0N / 25mm, more preferably 1.8~3.5N / 25mm) is.

The ratio of F ² and F ³ is, for example, F ² / F ³ = 1.5 or more (preferably 1.5 to 3.5, more preferably 2.0 to 3.0). Is desirable. The ratio of F ¹ and F ² is desirably, for example, F ¹ / F ² = 1.1 or more (preferably 1.2 to ² , more preferably 1.3 to 1.5).

Incidentally, F ¹ is releasably treated layer portion of the projecting end portion side is formed on a surface of (deployment site) side at the site of the protruding non end side (application site) of the support (for fixed pressure-sensitive adhesive layer Release adhesive layer and a pressure-sensitive adhesive layer (fixed pressure-sensitive adhesive layer) formed on the surface on the side of the applied part in the part facing the applied part. It can be adjusted according to the type of pressure-sensitive adhesive constituting the layer, the type of release treatment agent constituting the release treatment layer for the fixed pressure-sensitive adhesive layer, and the like.

Further, F ² is formed on mutually opposing surfaces in a portion (intermediate portion) between a portion on the end portion side where the support does not protrude (sticking portion) and a portion on the protruding end portion side (deployment portion). Since these are the peel forces between the applied temporary adhesive layers, these temporary adhesive layers (the first temporary adhesive layer to the m-th temporary adhesive layer; m is the number of opposing surfaces in the intermediate portion) It can be adjusted depending on the type of temporary adhering agent that constitutes.

Furthermore, F ³ is a pressure-sensitive adhesive layer (deployed pressure-sensitive adhesive layer) formed on the surface of the projecting end-side portion (deployed portion) of the support on the side of the non-projecting end-side portion (sticking site). And the peeling force between the release treatment layer (release treatment layer for the development adhesive layer) formed on the surface on the development site side at the site facing the development site, It can be adjusted according to the type of the pressure-sensitive adhesive constituting the adhesive layer, the type of the mold release treatment agent constituting the release pressure-sensitive adhesive layer release treatment layer, and the like.

  In addition, the adhesive force of the adhesive layer (adhesive adhesive layer) formed on the surface of the end portion side (applied part) where the support does not protrude is not particularly limited. Moreover, the adhesive force of the spread adhesive layer is not particularly limited.

(Support)
Although it does not restrict | limit especially as a support body (base material), For example, plastic base materials, metal base materials (For example, various metal foils, such as aluminum foil, iron foil, stainless steel foil, nickel foil, copper foil, etc.), Thin leaf bodies such as fiber base materials (for example, non-woven fabric) and paper base materials (for example, Japanese paper) can be mentioned. The support may have any form of a single layer or a laminate.

  In the present invention, a plastic substrate can be suitably used as the support. Examples of a material or material constituting the plastic substrate include polyolefin resins such as polyethylene (PE), polypropylene (PP), and ethylene-propylene copolymer; polyimide (PI); polyethylene terephthalate (PET), polybutylene. Polyester resins such as terephthalate (PBT); polyamide resins; methacrylate resins such as polymethyl methacrylate (PMMA); acrylic resins; polystyrene, acrylonitrile-styrene copolymer (AS resin), acrylonitrile-butadiene-styrene copolymer Styrenic resin such as coalescence (ABS resin); polycarbonate; urethane resin: epoxy resin; various resins such as fluorine resin. As the plastic substrate, a plastic substrate formed of a polyolefin-based resin (in particular, polyethylene or polypropylene, particularly polypropylene) is preferable from the viewpoint of flexibility and the like.

  The surface of the support (especially plastic substrate) is subjected to physical treatment such as corona treatment and plasma treatment, and chemical treatment such as primer for the purpose of improving adhesion with the adhesive layer. Appropriate surface treatments such as may be applied.

  Although it does not restrict | limit especially as thickness of a support body, Usually, it is 5-1000 micrometers (preferably 10-500 micrometers).

  As shown in FIG. 1, the support preferably has a structure formed continuously from the end of the pasting site to the end of the deployment site. That is, the support is preferably a support (one long sheet-like base material) having a structure formed continuously from one end to the other end. Thus, when the support is a long sheet-like base material, the folding-type adhesive tape or sheet has the original excellent flexibility possessed by one sheet-like base material. For example, even if the side surface of the folding adhesive tape or sheet is touched, the occurrence of injury is prevented. In addition, when the support is a long sheet-like base material, the thickness of the foldable adhesive tape or sheet can be effectively reduced. Further, if the support is a long sheet-like base material, due to its flexibility, the repulsive force when folded is small, and therefore, the opposing surfaces and surfaces for holding the folded state Therefore, the force (the peeling force between the opposing surfaces) when deploying in a long shape can be effectively reduced. Furthermore, since the surface of the support does not have a step and is a flat surface, when it is a foldable pressure-sensitive adhesive tape or sheet, it can be folded with the opposing surfaces in close contact with each other.

  On the other hand, when the support is a long one formed by superimposing and laminating the surfaces on the end side of a plurality of sheet-like base materials (“laminated long support”), each sheet Even if it is soft as a substrate, it is hard in the laminated part, so it is hard as a whole, and the foldable adhesive tape or sheet is hard. Moreover, since such a laminated elongate support body has a laminated part, the thickness at the time of setting it as a foldable adhesive tape or a sheet | seat will become thick. Furthermore, since the laminated long support is hard, the repulsive force when folded is large, and in order to maintain the folded state, the adhesive force between the opposing surfaces must be increased. In some cases, the force when deploying in a long shape is increased. In addition, since it may be difficult to bend at the laminated portion, the folding portion may be limited, and even when folded at the laminated portion, the repulsive force is large and it is difficult to maintain the folded state. Furthermore, since the surface of the laminated elongated support is not a smooth flat surface but has a step at the end of the laminated portion, when the foldable adhesive tape or sheet is used, The adhesion of is reduced.

Specifically, by sticking the fixed pressure-sensitive adhesive layer to the surface of the application site, it is possible to maintain the folded state of the application site and the site facing the application site. Of course, in this bonding, since the adhesive layer and the release treatment layer (peeling treatment layer) are used on the end side that does not protrude, the application site and the site facing the application site Is peelable, but since the release treatment layer is not formed on the crease portion side, the adhesion state is maintained. For this reason, as described above, the force that pulls the knob part is the part that adheres on the crease part side between the application part and the part facing the application part (adhesion part) after peeling at the peelable interface. ), It can be easily developed into a long shape without causing separation from the attached article.

[Paper diapers]
In the paper diaper (disposable diaper) of the present invention, the foldable adhesive tape or sheet is used as a constraining adhesive tape or sheet for holding the paper diaper in a rolled state. Such a paper diaper may be a so-called “paper diaper with tape” (or also referred to as “disposable diaper with tape”, “open type disposable diaper”, “open type disposable diaper”, etc.). Paper diapers are preferably used. The paper diaper may be an adult paper diaper or an infant paper diaper, but an infant paper diaper is preferred.

  The part for attaching the foldable adhesive tape or sheet to the paper diaper is not particularly limited. For example, as shown in FIG. 5, the part located in the vertical width region of the waist portion on the back surface of the paper diaper (FIG. 5). 6a) and a part (6b in FIG. 5) located at the waist of the paper diaper. As a part where the folding adhesive tape or sheet is affixed to the paper diaper, a part (6a in FIG. 5) located in the vertical width region of the waist part on the back side surface of the paper diaper is preferable from the viewpoint of preventing mischief of infants and the like.

  FIG. 5 is a schematic view showing an example of a pants-type paper diaper. In FIG. 5, 6 is a pant-type paper diaper, 6a is a part located in the vertical width region of the waist part on the back surface of the pant-type paper diaper, 6b is a part located in the waist part of the pant-type paper diaper, and A is a pant-type paper diaper. , B is the waist side of the pants-type paper diaper, and C is the front side of the pants-type paper diaper.

  When a foldable adhesive tape or sheet is affixed to a paper diaper, the longitudinal direction of the diaper may be affixed to the waistline direction or the vertical direction of the paper diaper. It is preferable. In particular, the foldable adhesive tape or sheet of the present invention has a long length when unfolded in a long shape, even if it is stuck so that the longitudinal direction is the waistline direction, so that the paper diaper is restrained in a rolled state. And can be long enough to hold it.

  Therefore, the foldable adhesive tape or sheet of the present invention may be affixed to a portion located in the vertical width region of the waist portion on the back side surface of the paper diaper so that the longitudinal direction is the waistline direction or the vertical direction. In particular, it is particularly suitable that the longitudinal direction is affixed to a portion located in the vertical width region of the waist portion on the back side surface of the disposable diaper so that the longitudinal direction is the waistline direction.

  When the foldable adhesive tape or sheet of the present invention is attached to a portion located in the vertical width region of the waist portion on the back side surface of the paper diaper so that the longitudinal direction is the waistline direction, as a foldable adhesive tape or sheet 1 to 2 or more can be used, but two are preferably used. For example, when two foldable adhesive tapes or sheets are attached to a portion located in the vertical width region of the waist on the back surface of the paper diaper so that the longitudinal direction is the waistline direction, as shown in FIG. It is preferable that the folds on the side where the knob part is not formed are pasted in a form where the creases face each other.

  FIG. 6 is a schematic view showing an example of a paper diaper to which the folding adhesive tape or sheet of the present invention is attached. In FIG. 6, 1, 6, A, and B are the folding adhesive tape or sheet, the paper diaper, the back side of the pants-type paper diaper, and the waist side of the pants-type paper diaper, respectively, as described above.

  As described above, when the foldable adhesive tape or sheet of the present invention is applied to a portion located in the vertical width region of the waist portion on the back side surface of the paper diaper so that the longitudinal direction is the waistline direction, the paper diaper is discarded. In this case, after rolling the crotch of the paper diaper from the crotch part to the front side, the waist part on both sides is further rounded to the front side. In this state, the foldable adhesive tape or sheet is unfolded and spread. Since it can be stuck and restrained using the agent layer, it is possible to round the waist part forward as compared with the case where it is stuck so that the longitudinal direction is the vertical direction. Paper diapers can be rolled up compactly. For this reason, it is possible to reduce the amount of garbage.

  In particular, the waist part on both sides can be rolled up and restrained to the front side, so even when the excrement is highly fluid excretion when it is rolled up, it effectively leaks from the part through which the leg of the paper diaper passes. It can be suppressed or prevented. Therefore, the paper diaper can be discarded in a state of being rolled up more hygienically than when the paper diaper is rounded only in the direction located on the trunk from the portion located on the crotch.

  In addition, since the foldable adhesive tape or sheet can be easily unfolded in a long shape, the time required for replacing the paper diaper can be shortened, and the diaper can be replaced more quickly.

  The foldable adhesive tape or sheet does not float between each part of the support and is extremely thin despite being folded. Therefore, even if the diaper is attached in advance to a paper diaper ( In particular, the appearance of a pants-type paper diaper is good.
