Description

  The present invention relates to a package for absorbent articles.

  Conventionally, absorbent articles such as sanitary napkins and panty liners (orimono sheets) are folded together with packaging materials, individually packaged, and marketed. As an example of this packaging form, a plurality of packages in which absorbent articles (sanitary napkins) are individually packaged by an exterior sheet are continuous, and can be separated for each package along a cut line portion formed in the package. A continuous package of absorbent articles (a continuous package of sanitary napkins) is known. For example, in the continuous package described in Patent Document 1, at least a part of the absorbent article is fixed to the inner surface of the exterior sheet. Specifically, each packaging body has the absorbent article and the exterior sheet along the direction orthogonal to the continuous direction in which the packaging body is continuous, with the back surface of the absorbent article and the inner surface of the exterior sheet facing each other. Are formed by being folded together. In the exterior sheet, an opening separation line portion is formed along a direction in which the packages are continuously connected, and the opening separation line portion includes the inner surface of the exterior sheet and the back surface of the absorbent article in a plan view of the packaging body. It is formed at a position different from the fixed portion.

  As another package, there is a package for containing the absorbent product in a state of being folded by a fold line along the width direction of the main body that is long in one direction. In this package, perforations for opening the main body material are formed on at least one surface of the bag-shaped main body. The perforation is formed so as to extend along a direction substantially coincident with the width direction of the main body of the absorbent product. A knob member is disposed at substantially the center of the perforated region. The knob member has a base end portion fixed to a region where the perforation is broken and opened, and a knob piece extending integrally from the base end portion. In the main body material, perforation cuts are disposed at locations on both ends in the width direction of the knob member in the break start region between the proximal end portion of the knob member and the knob piece (see, for example, Patent Document 2). .)

In the continuous packaging body of the absorbent article described in Patent Document 1, as shown in FIG. 8A, the packaging material 111 on both sides of the opening separation line portion 112 disposed on the packaging material 111 is fingered 121, 122. As shown in FIG. 8 (b), the first folding end portion 114 of the packaging material 111 and the release sheet 113 is bent, so that opening is easy. I couldn't. Further, this is a factor that damages the bonding portion 115.
Further, when there is no step in the vicinity of the opening separation line portion 112 near the center in the width direction in plan view, the packaging material 111 is broken by the fingers 121 and 122 along the opening separation line portion 112. As shown in c), a force for pressing the product (not shown) and a force for pulling the packaging material 111 in both directions (lateral direction) across the opening separation line portion 112 are required (indicated by arrows in the figure). It was.
In the package described in Patent Document 2, since the perforation is formed so as to extend along the direction substantially coincident with the width direction of the main body of the absorbent product, the product is intended to be opened directly from the perforation with a finger. There was a risk of damage.

  The present invention relates to providing a package for absorbent articles with improved ease of opening by devising the arrangement of components of the packaging material in the vicinity of the opening guide portion.

  The present invention is a package in which vertically long absorbent articles are individually packaged with an exterior material, and a clothing contact surface of the absorbent article is fixed to an inner surface of the exterior material by a fixing portion, The package body is folded at least twice in the longitudinal direction of the absorbent article with the wearer contact surface side of the absorbent article inside, and one end portion side of the exterior material in the longitudinal direction is the absorbent. An exterior material extending region extending outward from one end of the article, and the package is a region including the one end of the exterior material in the longitudinal direction and is an outer surface of the package. One exposed region, and extends from the first exposed region through the first fold, the central region, and the second fold, is located immediately inside the first exposed region with respect to the thickness direction, and the first exposed region An inner overlapping region that overlaps in plan view, and the outer covering material extension region includes the package. Comprising a tear guide portion to allow opening of the body, it said opening leading portion provides a package of the absorbent article overlapping at the fixed portion in plan view is provided on the inner overlapping region.

  The package of the absorbent article of the present invention prevents the inner member from floating or moving by the fixing part when the package is opened from the opening guide part, and damages the absorbent article. Absent. Furthermore, by disposing a packaging material or a packaging adhesive material in the vicinity of the inside of the opening guide part and providing a step in the vicinity of the opening guide part, the opening guide part can be easily broken and opened.

A preferred embodiment (first embodiment) of a package of absorbent articles according to the present invention will be described below with reference to FIGS. 1 to 3.
In the absorbent article package 20 of the present specification, “front” refers to the lower abdomen direction when the absorbent article is worn, and “rear” refers to the buttocks direction when the absorbent article is worn. Further, in this specification, in a state in which the garment is worn, the surface in contact with the wearer is referred to as a wearer contact surface or a skin contact surface, and is in contact with a relatively opposite surface, that is, the worn clothing. The side surface is referred to as a clothing contact surface or a non-skin contact surface. Further, the surface closer to the wearer is referred to as the wearer contact surface side or the skin contact surface side, and the surface closer to the clothing is referred to as the clothing contact surface side or the non-skin contact surface side.

  As shown in FIG. 1, the vertically long absorbent article 10 wrapped in the package 20 of the present embodiment is, for example, a sanitary napkin (hereinafter referred to as a napkin). Hereinafter, the napkin package will be described in detail. Therefore, the vertically long absorbent article 10 will be described as a napkin 10. Further, the longitudinal direction of the napkin 10 is the longitudinal direction. Hereinafter, the vertical direction refers to the vertical direction of the napkin 10 or a direction parallel to this direction.

As shown in FIG. 2, the napkin 10 includes a liquid permeable top sheet 1 disposed on the skin contact surface side, a liquid impermeable back sheet 2 disposed on the non-skin contact surface side, and a surface. A vertically long main body (also referred to as an absorbent main body) 4 having an absorbent body 3 having liquid retention properties interposed between the sheet 1 and the back sheet 2, and extending outwardly on both sides of the main body 4. A wing 5 is provided.
A slip stopper 13 for fixing the napkin 10 to the clothing is provided on the clothing contact surface of the back sheet. A release sheet 14 detachable from the misalignment stopper 13 is disposed so as to cover the misalignment stopper 13. Further, a release sheet fixing portion 15 for fixing the release sheet 14 is disposed on the inner surface of the exterior material 11, and the exterior material 11 is fixed to the release sheet 14. Therefore, the fixing portion 12 includes a slippage preventing portion 13 that fixes the clothing contact surface 10sw of the sanitary napkin 10 to the clothing, and a release sheet fixing portion 15 that fixes the release sheet 14 to the inner surface of the exterior material 11. Have.

The package 20 of the absorbent article is formed by folding the exterior material 11 together with the napkin 10 as the absorbent article in the vertical direction and sealing with the exterior material 11. Thus, the napkin 10 is individually packaged, and the clothing contact surface 10sw of the napkin 10 is fixed to the inner side surface of the exterior material 11 by the fixing portion 12. The term “fixed” as used herein refers to a state in which the clothing contact surface of the napkin 10 and the inner surface of the exterior material 11 do not move relative to each other in the packaged state. It may be indirectly fixed via the member. As an example in which both are indirectly fixed, a case where the both are fixed via a release sheet 14 as shown in FIG. In this case, as a fixing means between the members, a release sheet fixing means 15 which is a fixing means between the release sheet 14 and the exterior material 11, and a clothing contact surface 10 sw of the release sheet 14 and the sanitary napkin 10. There is a misalignment stopper 13 which is a fixing means. When both are overlapped in plan view, the overlapping portion of both is the fixing portion 12, and when both are not overlapping, the fixing portion 12 is the release sheet fixing portion 15. On the other hand, when there is no release sheet 14 and the garment contact surface 10sw of the sanitary napkin 10 is directly fixed by the shift stopper, the shift stopper 13 is the fixing part 12. The napkin 10 and the release sheet 14 are in a detachable fixed state, and the fixation between the release sheet 14 and the exterior material 11 is a stronger fixed state than the fixation between the napkin 10 and the release sheet 14, for example, difficult to peel off. It is preferable to be in a fixed state. The package 20 is folded at least twice in the longitudinal direction of the napkin 10 with the wearer contact surface 10 sm side of the napkin 10 facing inside. In the example of illustration, it is folded twice by folding at two places, the 1st folding part L1 and the 2nd folding part L2.
In the present specification, “peeling” means that it can be easily picked up with a finger and “adhesion” described later means that it cannot be easily picked up with a finger.

  When the exterior material 11 is folded together with the release sheet 14 and the napkin 10, the exterior material 11 has a size that includes them. In the folded state, the one end portion 11a side of the outer packaging material 11 in the vertical direction extends outward from the one end portion 10a of the sanitary napkin to form an outer packaging material extension region.

The package 20 of the present embodiment has a so-called three-fold structure, and the first exposed region 21 where the region including the one end portion 11a of the exterior material becomes the outer surface of the package 20, the first folded portion L1, and the first fold portion L1. A central region 23 between the second fold portion L2 and a region 22 including the other end portion 11b of the exterior material, which is a portion located immediately inside the first exposed region 21 and extending from the second fold portion L2. Yes. And the area | region 22 containing the other end part of exterior material overlaps with the 1st exposure area | region 21 by planar view, forms the overlap area 24, and is provided with the inner side overlap area | region 24a located in the inner side of a 1st exposure area | region regarding the thickness direction. Yes.
The exterior material 11 in the area of the first exposed area 21 in the overlapping area 24 is provided with an opening guide portion 25 that allows the package 20 to be opened. More specifically, the opening guide portion 25 is formed in an exterior material extension region in which the one end portion 11 a side of the exterior material 11 extends outward from the one end portion 10 a of the napkin 10. And the fixing | fixed part 12 provided in the inner side overlap area | region 24a which exists just inside the 1st exposed area | region 21, and the opening guide | induction part 25 are arrange | positioned so that it may overlap in planar view. In the packaging body 20 having the three-fold structure according to the present embodiment, the packaging body 20 overlaps with the fixing portion 12 disposed in the region 22 including the other end of the packaging body 20 in a plan view.
Further, the package 20 is configured by sealing the end portion of the first exposed region 21 and the region 22 including the other end portion by the package sealing portion 26. The package sealing portion 26 is arranged on the outer side in the longitudinal direction than the opening guide portion 25.

  In the napkin 10, since the opening guide part 25 is arranged on the fixed part 12, the following excellent effects are achieved. First, in the vicinity of the inside of the opening guide portion 25, a fixing portion 12 including a packaging material exterior material 11, a packaging adhesive material misalignment stopping portion 13 and a release sheet fixing portion 15 is arranged in a thick shape, and the opening guide portion 25 is arranged. By providing a step in the vicinity, the opening guide part 25 can be easily broken and opened. Moreover, when opening the package 20 from the opening guide part 25, the fixing part 12 prevents the inner member from the opening guide part 25 from floating or moving, and is easy to open. In addition, in the case of the three-fold structure as in this embodiment, the end of the exterior material 11 and the release sheet 14 in the region 22 including the other end is prevented from being bent inward (napkin 10 side), The slip prevention part 13 is not affected, the ease of peeling of the exterior material 11 is improved, and the product is easily opened. At the same time, since the fixing portion 12 exists at the opening position, the fixing portion 12 serves as a protective layer and does not damage the sanitary napkin 10.

The effects described above in the present invention will be described in detail. As shown in FIG. 3, when opening from the opening guide portion 25, the exterior material 11 on both sides of the opening guide portion 25 is often pressed with the fingers 31 and 32 to open from the opening guide portion 25. At this time, since the opening due to the thickness difference of the napkin 10 can be utilized, the opening is further facilitated, and the ease of opening is enhanced.
Further, when the fixing portion 12 is not arranged directly under the opening guide portion 25, the napkin 10 as the product is damaged because the napkin 10 as the product is strongly pressed by the fingers 31 and 32 through the exterior material 11. There were many. In particular, fingers with extended nails were easily damaged. However, as described above, the napkin 10 is less likely to be damaged by arranging the fixing portion 12 directly below the opening guide portion 25. For this reason, even if a force is applied in the thickness direction by the opening operation using the above-described step, it is not necessary to worry about damage to the napkin 10, so that it is easy to apply a force and the ease of opening is improved.
Further, since the product napkin 10 is not disposed directly under the opening guide portion 25, the product can be prevented from being touched at the time of opening, and damage to the product can be prevented.

  The opening guide portion 25 is arranged on the outer side in the vertical direction from one end portion of the napkin 10 in the first exposed region 21 in a state where the napkin 10 is folded. The distance between one end portion 10a of the napkin 10 in the first exposed region 21 and the opening guide portion 25 is preferably 5 mm or more, and more preferably 10 mm or more. By arranging in this way, it is possible to prevent the product from being damaged at the time of opening.

  The opening guide portion 25 includes a perforation lined in a line, an assembly of perforations lined in a predetermined width, and a cut line that does not cut in the thickness direction of the exterior material 11 arranged in a line. An assembly of cuts that do not lead to cutting in the thickness direction of the exterior material 11 that is linearly arranged with a predetermined width, a groove in which the tensile strength of the exterior material 11 is weakened linearly, and a tensile strength of the exterior material 11 that is dotted From the opening induction portion 25, the outer packaging material 11 on both sides of the opening induction portion 25 is pressed or pulled with a finger or the like with the opening induction portion 25 as a boundary, such as a group of holes weakened to a predetermined width. Any configuration may be used as long as the exterior material 11 is broken and the package 20 is opened, and dust or the like does not enter the package 20 and the cleanliness of the interior can be maintained.

  The misalignment stopper 13 is disposed on the non-skin contact surface side of the napkin 10 and is used when the napkin 10 is attached to the shorts. As the hot melt adhesive, rubber-based, olefin-based, ethylene vinyl acetate (EVA) -based, or the like can be used. The misalignment stopper 13 may be a so-called solid coating that is continuously applied, such as a planar shape, but in consideration of the adhesive remaining on the shorts in the coated area and the ease of taking out from the exterior material 11 It is preferable that the coating is intermittently applied. Examples of the intermittent application form include a spiral shape, a stripe shape extending in the width direction or the longitudinal direction, an Ω-shape, a dot shape, and the like. The misalignment stopper 13 is positioned substantially in the center in the front-rear left-right direction of the main body portion on the non-skin contact surface side of the napkin 10, the width is 35 mm or more and 70 mm or less, and the length is 65% or more and 95% of the length of the napkin 10. %, And from the viewpoint of preventing warping and slippage of the napkin 10 during use, including all the adhesive portions of the slip stop portion 13 and having a width that is substantially the same as or slightly smaller than the napkin 10 in plan view, Good length.

  The misalignment stopper 13 may exist from the center in the vertical direction of the napkin 10 to the vicinity of the tip of the napkin 10 beyond the first fold L1 and the second fold L2. The release sheet 14 covering the misalignment stopper 13 has a size that can cover the misalignment stopper 13, and is used by being bonded to the exterior material 11 by the release sheet fixing section 15.

  The release sheet fixing portion 15 uses a hot melt adhesive to bond and fix the release sheet 14 and the exterior material 11. The release sheet fixing portion 15 is made of, for example, a hot melt adhesive coating film. As this hot melt adhesive, rubber-based, olefin-based, EVA-based and the like can be used.

The release sheet fixing portion 15 extends in the direction of the end portion of the region 22 including the other end portion in the vertical direction from the region where the misalignment preventing portion 13 is present in plan view. Thereby, the bending of the exterior material 11 at the time of opening becomes difficult to influence to the slip prevention part 13. Further, by pulling up the end portion of the exterior material 11, the release sheet 14 is easily separated from the misalignment preventing portion 13 without stretching, so that the ease of peeling of the exterior material 11 after opening is improved. Moreover, since the free area | region of the exterior material 11 edge part decreases, the exterior material 11 becomes difficult to bend inward. When the misalignment stopper 13 is arranged on the outer side in the vertical direction from the release sheet fixing portion 15, the release sheet 14 is peeled from the misalignment stopper 13 by the release sheet fixing portion 15. The release sheet 14 adhered to the misalignment stopper 13 located on the outer side in the longitudinal direction than the release sheet 14 is stretched, and the release sheet 14 is difficult to peel off from the misalignment stopper 13. The extension length in which the release sheet fixing portion extends from the region where the misalignment is present to the end portion of the region including the other end portion in the vertical direction is preferably 1 mm or more, more preferably 5 mm. Further, it is preferably 30 mm or less, more preferably 20 mm or less.
In addition, the fixed portion 12 is a portion where the misalignment preventing portion 13 and the release sheet fixing portion 15 overlap in the overlapping region 24 in plan view. Furthermore, the opening guide part 25 is arranged on the fixed part 12 so as to overlap.

  The release sheet fixing portions 15 are intermittently present at a plurality of locations in the longitudinal direction across the longitudinal direction of the release sheet 14, thereby securely bonding the release sheet 14 and the exterior material 11 without wrinkles or slack. This is preferable. In the illustrated form, four fixing portions 15 are arranged intermittently in the vertical direction. Of the plurality of locations, the adhesive strength of the release sheet fixing portion 15 located closest to the end in the longitudinal direction is preferably higher than other locations. By doing in this way, when opening the opening guide part 25 or when peeling the napkin 10 from the release sheet 14, there is no damage to the members and the napkin 10, and the release sheet 14 can be removed from the exterior material 11. It is preferable from the viewpoint that there is nothing. As a method for increasing the adhesive strength, it is conceivable to increase the coating area. By increasing the application area, the adhesive area between the adhesive and the packaging material is increased, and the adhesive strength can be increased.

  The release sheet 14 is disposed to protect the shift stopper 13 on the product body side, but in the state where the napkin 10 is folded, one end in the vertical direction of the release sheet 14 and the other end Are preferably in an overlapping state. By becoming such a form, the rigidity in the folded state of the napkin becomes high especially in the overlapping portion, and the shape stability in the unexpected operation load before use is ensured.

The release sheet 14 may be made of the same material as a general napkin release sheet. Specifically, the application amount of glassine paper, polyethylene film, silicone treatment agent is, for example, 0.1 to 5 g. / M ² exfoliated fine paper, composites thereof and the like. This peeling treatment can be performed using a known method. Furthermore, the release sheet 14 may be of any size as long as the outer shape covers the misalignment stopper 13, and the shape is not limited.

  As the material of the exterior material 11, those conventionally used for packaging absorbent articles such as napkins can be used without particular limitation. Resin films such as polypropylene, polyester, polyethylene, polyvinyl alcohol, and the like can be used, and can be appropriately selected and used. In the case of non-woven fabrics, composite non-woven fabrics of spunbonded non-woven fabric (S) and melt-blown non-woven fabric (M) (SM, SMS, SMMS, etc.) in terms of sheet strength, liquid resistance (resistance to hot melt oozing) and sealing properties ) Is preferred. From the viewpoint of performing clear printing directly on the packaging material 11, a film material or a laminate structure of the film is also preferably used. In particular, the opening strength of the opening guide portion can be appropriately reduced by using an oriented material whose tearing strength in the continuous direction of the continuous package is lower than that in the width direction, and the ease of opening can be increased.

The sealing part 26 is made of, for example, a hot melt adhesive coating film. As this hot melt adhesive, rubber-based, olefin-based, EVA-based and the like can be used. In addition, adhesion by heat melting may be used.
The sealing portion 26 is preferably colored, and more preferably a colored hot melt. By coloring, the exterior material edge part of a 1st exposure area | region can be specified, and there exists an effect that it is easy to appeal to a user that the sealing degree as a product is ensured. There are systems in which ink or pigment is added as the colored hot melt, but a hot melt component that has a large absorption spectrum characteristically in the original visible absorption region may be selected. For example, it is conceivable to use a yellowish hot melt by means such as lowering the hydrogenation rate of a styrene-butadiene-styrene block copolymer which is one main component of the hot melt.

  The shape in the case of using a hot melt material for the sealing portion 26 may be any shape, and is often a straight line (coater coating) having a certain width, but spiral coating, summit coating, Ω coating, etc. It may be a pattern composed of curves. A pattern composed of curves is preferable in that it can be efficiently bonded with a small amount.

  The package 20 is further provided with side sealing portions 27 on both sides in the width direction, and seals the package 20 together with the sealing portion 26. The side sealing portion 27 is formed by means such as bonding with a hot melt adhesive coating film, thermal bonding between the exterior members 11 or bonding by embossing, or the like.

  The region where the sealing portion 26 and the side sealing portion 27 overlap has a tendency that the sealing strength tends to be extremely high, and the ease of opening may be significantly impaired. It is important. Examples include the provision of the sealing portion 26 in a form avoiding the side sealing portion 27 and the reduction of the width of the side sealing portion 27 on the sealing portion 26, but all of them reduce the size of the overlapping region. By doing so, the remarkable raise of sealing strength can be suppressed.

  Moreover, when the sealing part 26 or the side sealing part 27 is heat-sealed, as the forming material of the packaging material 11, the outer surface touching the sealing processing equipment has a higher melting point than the inner surface with which the napkin 10 abuts. By doing so, it is possible to ensure the seal adhesiveness by the low melting point layer while suppressing the contamination of the sealing processing equipment due to the material melting, and it is possible to achieve both the seal adhesiveness and the processing stability. By reducing or not providing the thickness of the high melting point layer in the overlapping region 24, it is possible to achieve both further seal adhesion and processing stability.

  The first exposed region 21 is preferably longer in the longitudinal direction of the first exposed region 21 and in the longitudinal direction of the region 22 including the other end portion 11b. This is because, when the opening guide part 25 is broken and opened and the napkin 10 is deployed, the first exposed region 21 is first deployed and then the region including the other end 11b is developed. This is because the ease of the unfolding operation is increased. It is preferable that there is an appropriate distance between the end 10a of the first exposed region 21 on the first exposed region side of the napkin 10 and the other end 11b, because it is difficult to cause interference in the operation of both hands when opening. . Specifically, the distance is preferably 5 mm or more and 20 mm or less, and more preferably 7 mm or more and 18 mm or less.

  In the napkin 10, the exterior material of the region 22 including the other end portion 11b is folded back to the first exposed region 21 side, and the exterior material end portion 11b is exposed to the outer surface side from the first folded portion L1. 1 (ie, located above the first fold line L1 in FIG. 1B), and the exterior material end portion 11a in the first exposed region 21 is also exposed to the outer surface side from the first fold portion L1. The ends are joined together. This configuration is a preferable configuration from the viewpoint of easy sealing by heat sealing.

  In a state where the napkin 10 is folded, if the release sheet fixing portion 15 provided in the region 22 including the sealing portion 26 and the other end portion 11b overlaps in plan view, the sealing portion 26 at the time of opening operation It is preferable from the standpoint that the load applied to can be reduced and the ease of opening is increased.

  In the above-described configuration, the form in which the sealing portion 26 exists closer to the exterior material end side in the longitudinal direction than the opening guide portion 25 is disclosed, but the exterior material end portion and the central region in the longitudinal direction of the opening guide portion 25 are disclosed. If it is the structure which has a sealing part on both sides of this, it is preferable from a viewpoint that it does not reach the inside of the napkin 10 with respect to the fine foreign material which passes the opening part of a fracture line. In that case, the sealing strength of the sealing portion closer to the center region than the opening guide portion 25 must be weak enough to be peeled off. As means for weakening the sealing strength, means such as reducing the amount of hot melt applied, or subjecting the inner surface of the outer packaging material to a peeling treatment can be considered.

  Since the end portion 11 a of the exterior material 11 in the first exposed region 21 is a portion that is held during the opening operation, it is preferable that the end portion 11 a is not sealed by the sealing portion 26 and the side sealing portion 27. As a means for this, the sealing part 26 is not provided at the end of the exterior material 11, the dimensions of the side sealing part 17 are reduced, and two types of resins having different melting points as the forming material of the packaging material 11 have a layer structure. From the viewpoint of ease of opening, it is preferable that the sealing layer is not sealed or the sealing strength is weakened by a method such as providing or increasing the thickness of the high melting point layer only at the end portion.

  When it has a pair of wing part 5 extended from the both ends of the vertical direction of the napkin 10, it is better that the longitudinal direction edge part of the wing part 5 is folded by the 1st folding part L1 or the 2nd folding part L2. This is because, in the folded state, the restoring force for returning to the expanded state is stored in the sanitary napkin 10, and the external force necessary for the expansion is reduced, so that the ease of opening is increased. .

  When the wing portion 5 is provided with a slip stopper, a separate release sheet for wing is used to protect and cover the slip stopper. It is preferable that the release sheet for wings is not folded at the first fold part L1 and the second fold part L2 from the viewpoint of stably protecting and covering the misalignment hot melt. When the napkin is folded around the longitudinal end of the release sheet for wings, the napkin is more rigid in the folded state, and the shape stability can be improved under unexpected operating loads (packaging and sales of products) before use. Secured.

  The wing 5 is made of a soft non-woven fabric having a high water repellency and a low fiber density, and its base is sandwiched and fixed between the top sheet 1 and the back sheet 2. Each wing 5 has an adhesive portion (not shown) on the back side. This pressure-sensitive adhesive part is for fixing the wing 5 to the underwear and preventing the napkin 10 from shifting with respect to the underwear. Various pressure-sensitive adhesives can be used without any particular limitation.

Moreover, as shown in FIG. 4, it is preferable that the absorber 3 of the napkin 10 has a thin portion 16 that is partially recessed from the periphery in the thickness direction of the product. An example of the form of the thin portion 16 is a groove. In FIG. 4, a groove that is recessed from the skin contact surface side toward the non-skin contact surface side is provided. And in the state which folded the napkin 10, it is preferable that the opening guidance | induction part 25 and a part of thin part 16 correspond in planar view. The thin portion 16 has a depth of 0.5 mm or more, preferably 1 mm or more, more preferably 2 mm or more, and a depth of 20 mm or less, preferably 8 mm or less, more preferably 5 mm or less. . And it has a depth of 0.5 mm to 20 mm, preferably 1 mm to 8 mm, more preferably 2 mm to 5 mm.
In this case, the unsealing property of the unsealing guide portion 25 can be further enhanced by the step difference due to the depth of the thin portion 16. That is, since the opening guide line 25 can be easily pushed in the thickness direction by utilizing the thickness difference between the thin portion 16 and the surrounding portion, the opening guide portion 25 is easily broken and opened easily. In addition, since the strength is secured by the fixing portion 12, even if the thin portion 16 is present in the napkin 10 that is an absorbent article in a portion through which the opening guide portion 25 passes in plan view, the thin portion 16 may be damaged at the time of opening. It is suppressed.

Although not shown in the drawings, it is preferable that the particles are dispersed inside the napkin 10 at a position inside the release sheet 14 in the plan view of the package 20 in the developed state. Examples of the granules include absorbent polymers and deodorants. The particle size is 10 μm or more, preferably 50 μm or more, more preferably 200 μm or more, and is 2000 μm or less, preferably 1000 μm or less, more preferably 500 μm or less. And they are 10 micrometers or more and 2000 micrometers or less, Preferably they are 50 micrometers or more and 1000 micrometers or less, More preferably, they are 200 micrometers or more and 500 micrometers or less. The absorbent polymer is not particularly limited as long as it satisfies the characteristics. Specifically, for example, sodium polyacrylate, (acrylic acid-vinyl alcohol) copolymer, sodium polyacrylate cross-linked product, (starch -Acrylic acid) graft polymer, (isobutylene-maleic anhydride) copolymer and saponified product thereof, potassium polyacrylate, and cesium polyacrylate. Examples of the deodorant include zeolite and activated carbon.
As described above, the particles are dispersed on the absorbent body (not shown) of the napkin 10, so that the ease of opening is enhanced by utilizing the steps due to the particles. However, the fixed portion 12 disposed in the vicinity of the opening guide portion 25 that is most pressurized during opening prevents the granules from being strongly pressed against the back sheet (not shown) of the napkin 10 by the pressing force during opening. Is done. Thereby, it is prevented that a pinhole arises in a back seat by a granular object. That is, it is possible to prevent damage to the back sheet that may lead to leakage from the back sheet.

As shown in FIG. 5, the absorbent body 3 of the napkin 10 preferably has a thick portion 17 that protrudes partially toward the skin contact surface side in the thickness direction of the product. The thick portion 17 includes a portion having a thickness greater than that of both side portions at least in the central portion in the width direction. That is, the napkin 10 has a so-called medium-high structure. And in the folded state of the napkin 10, the opening guide part 25 is arranged at a position overlapping the thick part 17 in plan view. The wall thickness portion 17 has a height of 0.5 mm or more, preferably 1.0 mm or more, more preferably 2.5 mm or more, and 15 mm or less, preferably 10 mm or less, more preferably in the deployed state. Has a height of 5 mm or less. And it has a height of 0.5 mm or more and 15 mm or less, preferably 1.0 mm or more and 10 mm or less, more preferably 2.5 mm or more and 5 mm or less.
In this case, the ease of pushing in the thickness direction is increased due to the step difference due to the height of the thick portion 17 existing in the central portion in the width direction and the portion having a smaller thickness than the thick portions existing on the left and right sides thereof. The unsealing property of the part 25 can be improved. That is, since the opening guide part 25 is easily broken using the step, the opening is facilitated.

  Further, as shown in FIG. 6, a plurality of the packages 20 are continuously present in the same direction as the disposing direction of the opening guide portion 25. That is, the individual packaging bodies are continuous packaging bodies that are continuously arranged, and the individual packaging bodies 20 can be freely separated by the separation guide portions 28 disposed on the side sealing portions 27. The separation guide portion 28 is formed by perforations. Alternatively, as in the case of the opening guide portion 25, the perforations arranged linearly, the aggregates of perforations arranged linearly with a predetermined width, and cut in the thickness direction of the exterior material 11 arranged linearly Breaks that do not reach, aggregates of cuts that do not lead to cutting in the thickness direction of the exterior material 11 arranged in a line with a predetermined width, grooves that weaken the tensile strength of the exterior material 11 linearly, tensile strength of the exterior material 11 The exterior material 11 is broken from the separation guide portion 28 by pulling both sides of the separation guide portion 28 as a boundary, such as an assembly of holes weakened in a dotted shape in a line shape with a predetermined width. Any structure may be used as long as it is a physical property that cannot be separated by an operation load assumed at the time of display at a sales place. In order to separate individual packages from the continuous package, they are separated by a normal separating operation. For example, it is possible to detach by holding both sides of the detachment guide part 28 with fingers and pulling in a direction perpendicular to the detachment guide part 28 or tearing it off at the separation guide part.

As described above, since the separation guide portion 28 is arranged in a direction perpendicular to the arrangement direction of the opening guide portion 25, the separation guide portion 28 is separated without being affected by the tensile force required when the opening guide portion 25 is opened. The required tensile force can be designed.
In addition, since the separation guide portion 28 is arranged in a direction perpendicular to the arrangement direction of the opening guide portion 25, the tensile force applied when the individual package body 20 is separated from the separation guide portion 28 is different from that of the individual package body 20. Since it is different from the direction of the pulling force that opens the opening guide part 25, the opening guide part 25 is difficult to break at the time of separation. However, in the case of continuous wrapping, when the separation guide part is folded alternately and stored in a bellows shape, or when folded at the separation guide part and hung on a string or stick stretched horizontally, the separation guide part From the viewpoint of being easily maintained in a broken state, it is preferable that the end portion of the separation guide portion is notched or only partially cut.

  Arbitrary printing is preferably performed on the exterior packaging material 11 of the continuous package in terms of aesthetics and recognition of product features. Furthermore, it is preferable on manufacture that the printing pattern in the continuous direction of a continuous package has a certain periodicity. In the continuous direction of the continuous package, the shortest length from the printing position until the same printing appears is called a printing pitch. When the printing pitch matches the interval between the arrangement position of the napkin 10 and the arrangement position of another adjacent napkin 10 in the continuous direction of the continuous package, the same pattern printing is performed for each of the arrangement positions of the napkin 10. It is possible to apply. In this case, it is preferable to provide a rectangular black mark called an eye mark that serves as a mark for synchronizing the printing pitch and the napkin interval. If the pitch between the arrangement position of the napkin 10 and the arrangement position of another adjacent napkin 10 does not coincide with the printing pitch, a printing pattern appears randomly in the continuous direction of the continuous package instead of having to apply an eye mark. In this case, however, the printing pitch is made smaller than the interval between the arrangement position of the napkin 10 and the arrangement position of another adjacent napkin 10 so that all the information existing in the printing pitch is stored in one sheet of the napkin 10. One or more is always preferable because it can be described.

  However, different information can be described in two or more napkins 10 adjacent to each other by setting the printing pitch to be twice or more larger than the interval between the arrangement position of the napkin 10 and another adjacent napkin 10. . By doing so, it is possible to enjoy the change of the print pattern when purchasing the product, which is preferable from the viewpoint of palatability.

Although this invention demonstrated the packaging form which folded the napkin 10 in three, it can be applied also to the package at the time of making the napkin 10 folded in four.
As shown in FIG. 7, the package 20 (20 b) has a packaging form in which the napkin 10 is folded in the vertical direction, and basically the packaging of the above-described three-folded napkin 10 except for the folding method. It is the same as the form. Specifically, the napkin 10 is folded three times by being folded at three locations of the first fold L1, the second fold L2, and the third fold L3 with the wearer contact surface 10sm side inward. ing.
That is, the clothing contact surface 10 sw of the napkin 10 is fixed to the inner surface of the exterior material 11 by the fixing portion 12. The napkin 10 and the release sheet (not shown) are in a detachable fixed state, and the fixation between the release sheet and the exterior material 11 is a stronger fixed state than the fixation between the napkin 10 and the release sheet. For example, a fixed state that is difficult to peel off is preferable.
When the exterior material 11 is folded together with the release sheet or the napkin 10, the exterior material 11 has a size that includes them. In the folded state, the one end portion 11a side of the outer packaging material 11 in the vertical direction extends outward from the one end portion 10a of the sanitary napkin to form an outer packaging material extension region.

The package 20b has a so-called four-fold structure, and the first exposed region 21 in which the region including the one end portion 11a of the exterior material becomes the outer surface of the package 20b, the first folded portion L1, and the second folded portion. Immediately inside the first central region 23a extending from the first central region 23a between the second folded region L2 and the second central region 23b between the second folded portion L2 and the third folded portion L3, and the third folded portion L3. And a region 22 including the other end portion 11b of the exterior material, which is a portion located in the area. The second central region 23b is positioned immediately inside the first exposed region 21, and includes an inner overlapping region 24a that overlaps the first exposed region and is positioned inside the package 20b.
The exterior material 11 of the first exposed region 21 in the overlapping region 24 is provided with an opening guide portion 25 that allows the package 20b to be opened. More specifically, the opening guide portion 25 is formed in an exterior material extension region in which the one end portion 11 a side of the exterior material 11 extends outward from the one end portion 10 a of the napkin 10. And the fixing | fixed part 12 provided in the overlap area | region 24 which exists just inside the 1st exposure area | region 21, and the opening guide | induction part 25 are arrange | positioned so that it may overlap in planar view. In the packaging body 20 having the three-fold structure according to the present embodiment, the packaging body 20 overlaps with the fixing portion 12 disposed in the region 22 including the other end of the packaging body 20 in a plan view.

  This package 20b also has the same effects as the package 20 shown in FIG. Therefore, it can be easily broken and opened from the opening guide portion 25. Moreover, when opening the package 20 from the opening guide part 25, the fixing part 12 prevents the inner member from the opening guide part 25 from floating or moving, and is easy to open. In addition, even in the case of the four-fold structure as in the present embodiment, the end of the exterior member 11 and the release sheet in the region 22 including the other end is bent inward (the sanitary napkin 10 side). It is prevented and does not affect the misalignment stopper (not shown), the ease of peeling of the exterior material 11 is improved, and the product can be easily opened. At the same time, since the fixing portion 12 exists at the opening position, the fixing portion 12 serves as a protective layer and does not damage the sanitary napkin 10.

Next, an example of a method for removing the napkin 10 by peeling off the packaging material 11 and the like of the package 20 will be described below with reference to FIG.
As shown in FIG. 8, the both sides of the opening guide part 25 of the folded exterior material 11 are pushed with fingers 31 and 32 (for example, thumbs) of both hands, and the exterior material 11 on both sides of the opening guide part 25 is opened. By pulling in the both directions across 25, the opening guide portion 25 is broken and opened. At this time, since the fixing portion 12 exists on the inner side of the opening guide portion 25, the fixing portion 12 serves as a protective layer and the sanitary napkin 10 is not damaged. Moreover, since the level | step difference of the fixing | fixed part 12 can be utilized, opening operation becomes easy.
Then, the exterior material 11 is peeled off from the napkin 10 together with the release sheet 14, and the napkin 10 is attached to a predetermined position of shorts (not shown) from the part where the release sheet 14 is peeled off. Finally, the exterior material 11 is completely peeled off from the napkin 10 together with the release sheet 14, and the entire region of the shift stopper 13 of the napkin 10 is attached to the shorts.

  The napkin 10 can have the same packaging form regardless of the presence or absence of wings (not shown). Further, like the sanitary napkin 10, the urine leak pad can be in the same packaging form.
