[Problems to be solved by the invention]

The subject to be solved by the present invention is at least one of the following first and second problems. In the first document, in the case of the absorbent article package, when the guide tape is pulled in the longitudinal direction, the position where the strongest force acts, that is, the longitudinal direction of the packaging sheet, is the end portion. The packaging sheet is not smoothed. In this case, the "end portion" of the packaging sheet may become the base point at which the base end portion (i.e., the joint portion) of the guide tape is peeled off. In this state, the entire fixing portion of the guide tape is self-wrapped at the end of the sheet. The edge is peeled off, and only the tape is peeled off from the packaging sheet.

The present invention has been made in view of the above problems, and an object thereof is to provide an absorbent article package in which a joint portion of a guide tape is not easily detached when unfolded.

The second problem is an absorbent article package provided with a guide tape, and a free end portion of the guide tape that protrudes outward from an end edge portion of the packaging sheet is peelably adhered to the packaging sheet. Further, when the absorbent article is used, the free end portion of the leader tape (that is, the pick-up portion of the leader tape) is peeled off from the packaging sheet, and the free end portion which has been peeled off is grasped with a finger and pulled. In this way, the individual packages are opened. However, as in Patent Document 1, there is a case where the packaging sheet is formed of a non-woven fabric, and when the guide tape which has been adhered is peeled off, the fibers on the surface of the nonwoven fabric are peeled off. In this case, the packaging sheet may be broken due to the large peeling of the fibers, or the adhesion may be lost due to adhesion of the already peeled fibers to the adhesive portion of the leader tape.

The present invention has been made in view of the above problems, and an object thereof is to provide an absorbent article package for a packaging sheet having a non-woven fabric, when peeling off a picking portion of a guide tape which has been adhered to the packaging sheet, It is possible to suppress fiber peeling of the nonwoven fabric.

=== First Embodiment === <Structure of the absorbent article package> As an example of the absorbent article package (individual package) of the first embodiment, the sanitary napkin 1 (hereinafter also referred to as For [sanitary cotton 1]). In addition, although the sanitary napkin 1 is described below, the absorbent article package of the present embodiment also includes a so-called secretion sheet (for example, a pad), an incontinence pad, and the like, and is not limited to the sanitary napkin.

Figure 1 is a schematic perspective view of a sanitary napkin 1 in an individually wrapped state that has been folded. Fig. 2 is a schematic plan view of the sanitary napkin 1 when it has been unfolded from the skin side. Fig. 3 is a schematic plan view of the sanitary napkin 1 when the unfolded state is viewed from the non-skin side. Figure 4 is a schematic cross-sectional view showing the A-A section of Figure 2.

As shown in FIGS. 1 to 4, the sanitary napkin 1 of the present embodiment includes an absorbent article 10, a packaging sheet 20, and a guide tape 50. Further, a separator 30 is provided between the absorbent article 10 and the packaging sheet 20 in the thickness direction.

In the following description, as shown in FIGS. 1 to 4, each direction is defined. In other words, the direction along the longitudinal direction of the product of the sanitary napkin 1 (absorbent article 10, packaging sheet 20) in the expanded state is referred to as "longitudinal direction". The longitudinal direction has [front side] and [rear side]. This [front side] is the direction of the abdomen side of the user when the absorbent article 10 is used, and the [rear side] is the direction of the back side of the user when the absorbent article 10 is used. Further, the direction orthogonal to the longitudinal direction, that is, the direction along the width direction of the product is referred to as [lateral direction]. Further, the direction orthogonal to the longitudinal direction and the lateral direction is referred to as a "thickness direction", and the side where the absorbent article 10 is worn (when worn) and the skin of the user (wearer) is referred to as [ The skin side] and the opposite side are called [non-skin side].

The absorbent article 10 has an absorbent core material 11 that absorbs liquid, covers the top sheet 12 of the absorbent core 11 from the skin side of the user, and covers the back surface of the absorbent core 11 from the non-skin side of the user. Sheet 13 (see Fig. 2, Fig. 4).

The absorbent core member 11 is a member that is elongated in the longitudinal direction and contains hydrophilic fibers, pulp, and the like, and can efficiently absorb a liquid such as a body fluid. The absorbent core material 11 can be formed by laminating a hydrophilic fiber or a powder by an air-laid method, or an air-laid sheet in which a hydrophilic fiber or a powder is formed into a sheet by an air-laid method. . The top sheet 12 has a center top sheet 12A that is superposed on the skin side of the absorbent core member 11 and a side top sheet 12B that is superposed on both sides in the lateral direction of the center top sheet 12A. Each of the center top sheet 12A and the side top sheet 12B is a liquid permeable sheet member that allows liquid such as body fluid to pass through, and is formed of, for example, a nonwoven fabric. However, the material is not limited as long as it is a member having a sheet member having a structure for permeating a liquid and is in contact with the skin of the user when the sanitary napkin 1 is used. For example, it may be a woven fabric, a mesh sheet, or the like. The back sheet 13 is a liquid-impermeable sheet member, and is formed by bonding a film of an air-permeable resin film to a nonwoven fabric such as polyethylene, acryl or the like, a breathable resin film, a nonwoven fabric such as a spun bond or a water needle, or the like. . Since the back sheet 13 is liquid-impermeable, when the sanitary napkin 1 is used, it is possible to suppress the liquid absorbed by the absorbent core 11 through the top sheet 12 (12A, 12B) toward the garment side of the underwear or the like ( Non-skin side) exudation.

The packaging sheet 20 is a sheet member for individually packaging the absorbent article 10. This packaging sheet 20 is joined in a state in which the absorbent article 10 is overlapped in the thickness direction before the use of the sanitary napkin 1, and when the sanitary napkin 1 is used, the self-absorbent article 10 is removed. In the present embodiment, the packaging sheet 20 is a substantially rectangular sheet member having a long side in the longitudinal direction (longitudinal direction), and the absorbent article 10 and the packaging sheet 20 are passed through the separator 30, and a hot melt adhesive is provided. The main body adhesive portion 131 and the packaging sheet joint portion 132 of the adhesive are joined (see FIG. 4). The region of the predetermined width of the end portion 20ef including the one side (the front side in the longitudinal direction in FIG. 2) in the longitudinal direction of the packaging sheet 20 in the unfolded state is referred to as the first end edge portion 20rf, and will be A region having a predetermined width of the end portion 20eb on the other side (the rear side in the longitudinal direction in FIG. 2) in the longitudinal direction is referred to as a second end edge portion 20rb. Further, a region in which the predetermined width of the end portion 20es of the packaging sheet 20 is included in the lateral direction is referred to as a side end portion 20rs.

As the material of the packaging sheet 20, a non-woven fabric such as an SMS (spunbond/meltblown/spunbond) nonwoven fabric can be used. In the conventional absorbent article package (package body), a package sheet such as a resin or a film is often used. Further, in the sanitary napkin 1 of the present embodiment, by using the packaging sheet 20 made of non-woven fabric, the compression sound of rust is less likely to occur at the time of opening, and it is difficult to be found by others when the sanitary napkin 1 is used. Moreover, the user (wearer) can feel at ease by not being able to weave a unique soft skin touch.

The packaging sheet 20 is subjected to a predetermined embossing process in the thickness direction over the entire area of the nonwoven fabric surface. For example, in a state in which a spunbonded nonwoven fabric, a melt-blown nonwoven fabric, or the like has been laminated, a part of the surface of the packaging sheet 20 is formed with a plurality of portions which have been pressurized and heated into a small dot-like portion, that is, a hot-melt portion ( Not shown). Thereby, the packaging sheet has a predetermined density ρ20 and a predetermined thickness t20. Further, the density ρ20 is a value calculated by measuring the weight of the packaging sheet 20 cut into a predetermined size (area). Further, for the thickness t20, for example, a dial thickness gauge ID-C1012C manufactured by Mitutoyo Instruments Co., Ltd. or an instrument equivalent to the thickness gauge is used, and the contact area is set to 20 cm ² and the contact is made. The pressure was set to 3 gf/cm ² , and the average value of the measured values was measured for a plurality of portions of the surface of the nonwoven fabric.

Further, in a predetermined region of the packaging sheet 20, a high-density portion 25 is formed by performing a compression process different from the embossing process described above. In the high-density portion 25, the density is higher than the predetermined density ρ20, and the thickness is thinner than the predetermined thickness t20. The compression processing for forming the high-density portion 25 is performed by performing a known press working such as rolling treatment or embossing on a predetermined region of the packaging sheet 20 (non-woven fabric). Therefore, in the high-density portion 25, by pressing and fixing the fibers on the surface of the nonwoven fabric, the fine unevenness of the surface is reduced as compared with the region where the high-density portion 25 is not formed, and a smooth state is formed.

In the packaging sheet 20 of the present embodiment, as shown by the blackened portion in FIG. 3, the first high-density region 251, the second high-density region 252, the third high-density region 253, and the fourth high are respectively along the lateral direction. The four high-density regions of the density region 254 are arranged in the vertical direction. In addition, in FIG. 2, for the convenience of description, the display of the high-density areas 251-254 is abbreviate|omitted. The respective high-density regions 251 to 254 are formed by arranging a plurality of high-density portions 25 having a predetermined size and shape at intervals in the lateral direction. Among them, the first high-density region 251 is formed at a position overlapping with the first end edge portion 20rf of the packaging sheet 20. In addition, in the following description, the area of the plurality of high-density portions 25 forming the first high-density region 251 at the position overlapping the guide belt 50 (base end portion 50s) in the lateral direction is large. The density portion 25 is a central high-density portion 251c, and a plurality of high-density portions 25 provided on both sides in the lateral direction of the central high-density portion 251c are the both-side high-density portions 251s.

A guide tape 50 is provided on the first end edge portion 20rf (end portion 20ef) of the packaging sheet 20. The guide tape 50 is formed of, for example, a polypropylene film, and the base end portion 50s is joined and fixed to the non-skin surface of the first end edge portion 20rf at the other end portion in the longitudinal direction. The fixing of the base end portion 50s is performed via the adhesive layer 55 formed of an adhesive such as a hot melt adhesive. In addition, the end portion on the one side in the longitudinal direction of the guide tape 50 is formed at a free end portion that protrudes toward the outer side (the front side in the longitudinal direction) of the first end edge portion 20rf (end portion 20ef) of the packaging sheet 20 in the longitudinal direction. 50f. Details of the structure and function of the guide tape 50 will be described later.

The separator 30 is a sheet member disposed between the back sheet 13 of the absorbent article 10 and the packaging sheet 20 (see FIG. 4). The skin side surface of the separator 30 is peeled off by using a resin or the like, and is detachably adhered to the body adhesive portion 131 provided between the absorbent article 10. The peeling process is a conventional process, and the description is omitted here. Further, the non-skin side surface of the separator 30 is fixed (joined) to the packaging sheet by the packaging sheet joint portion 132 provided between the packaging sheet 20. By arranging such a separator 30, it is possible to suppress the adhesion of the adhesive forming the body adhesive portion 131 to the packaging sheet 20 before the use of the absorbent article 10, the adhesion of the body adhesive portion 131 becomes weak, and the like, and the adhesion of the body can be protected. Part 131. Moreover, when the absorbent article 10 is used, the separator 30 is peeled off from the main body adhesive portion 131 together with the packaging sheet 20, and the absorbent article 10 is fixed to the user's underwear or the like by the adhesive force of the main body adhesive portion 131.

In the present embodiment, the sanitary napkin 1 in an individual package state is folded in the longitudinal direction by a plurality of creases in the lateral direction. Specifically, the sanitary napkin 1 is folded into three folds in the longitudinal direction by the two creases F1 and F2. The first crease F1 is disposed on the rear side of the center of the sanitary napkin 1 in the longitudinal direction, and the second crease F2 is disposed on the front side of the center of the sanitary napkin 1 in the longitudinal direction (see FIG. 1). ,figure 2).

<Individual Packaging of Sanitary Cotton 1> Next, the individual packaging state of the sanitary napkin 1 will be described. Figure 5 is a schematic plan view of the sanitary napkin 1 in an individually wrapped state that has been folded. Fig. 6 is a schematic cross-sectional view showing a section B-B of Fig. 5. Further, in Fig. 6, the separator 30 is not shown for convenience of explanation.

As described above, the sanitary napkin 1 is folded by the two creases F1, F2 so that the absorbent article 10 is formed into an individual packaged state in which the packaging sheet 20 is packaged. When the sanitary napkin 1 is folded, first, the packaging sheet 20 and the absorbent article 10 (and the separator 30) are bent in the longitudinal direction to the skin side surface of the absorbent article 10 with the first crease F1 as a base point. Become inside. In other words, the second end edge portion 20rb (end portion 20eb) of the packaging sheet 20 is folded back toward the inside from the outer side in the longitudinal direction (longitudinal direction) with the first crease F1 as a base point. Next, the packaging sheet 20 and the absorbent article 10 (and the separator 30) are bent in the longitudinal direction by using the second crease F2 as a base point. In other words, the first end edge portion 20rf (end portion 20ef) of the packaging sheet 20 is folded back toward the inside from the outer side in the longitudinal direction (longitudinal direction) with the second crease F2 as a base point. In the sanitary napkin 1, the first end edge portion 20rf of the packaging sheet 20 is formed in a state of being disposed on the outer side (the upper side in FIG. 6) closer to the thickness direction than the second end edge portion 20rb.

An end portion region 27 as shown in FIGS. 5 and 6 is formed in a region where the first end edge portion 20rf of the packaging sheet 20 overlaps the packaging sheet 20 in the thickness direction. The end portion region 27 is formed between the side end portions 20rs and 20rs on both sides in the lateral direction of the packaging sheet 20, and is formed by coating the adhesive agent in a strip shape in the lateral direction, as shown in FIG. The lower surface of the one end edge portion 20rf is joined to the upper surface of the packaging sheet 20 which is overlapped with the first end edge portion 20rf. By the end portion region 27, the packaging sheets 20 stacked in the thickness direction are joined to each other at the first end edge portion 20rf, and it is possible to suppress the folded state from being unfolded before the use of the sanitary napkin 1 is started. That is, the sanitary napkin 1 capable of suppressing the individual packaging state can be naturally opened or the like.

Further, in the side end portions 20rs on both sides in the lateral direction of the packaging sheet 20, a sealing region 29 in which the packaging sheets 20 which have been superposed in the thickness direction are joined (sealed) in the longitudinal direction is formed. The sealing region 29 is formed by a conventional sealing means such as ultrasonic welding or heat fusion. Thereby, the folded packaging sheets 20 are joined to each other at the side end portions 20rs on both sides in the lateral direction, and as shown in Figs. 1 and 5, the sanitary napkin 1 is easily maintained in the individually wrapped state in which the napkins 1 have been folded.

In this manner, the sanitary napkin 1 that is folded to form an individual package state is adhered to the package via the adhesive layer 55 at the free end portion 50f of the guide tape 50 that protrudes outward in the longitudinal direction from the first end edge portion 20rf of the packaging sheet 20. The surface of the sheet 20. That is, the guide tape 50 is disposed to span the end portion 20ef of the packaging sheet 20 (refer to FIG. 6). Further, the free end portion 50f of the guide tape 50 is peelably adhered to the surface of the packaging sheet 20, and when the sanitary napkin 1 is used, it can be easily peeled off from the surface of the packaging sheet 20. Further, since the base end portion 50s of the guide tape 50 is press-contacted to the packaging sheet 20 and has high joint strength, it is less likely to be peeled off from the surface of the packaging sheet 20 than the free end portion 50f.

When the absorbent article 10 is used, the sanitary napkin 1 which is bent at the first crease F1 and the second crease F2 is unfolded as shown in FIG. 2 to form the packaging sheet 20 and the separator. 30 performs an action of detaching from the absorbent article 10. When the sanitary napkin 1 is unfolded from the individual packaging state, the free end portion 50f of the guide tape 50 is grasped by the finger of the user or the like, from the inner side in the thickness direction to the outer side and from the one side in the longitudinal direction toward the other side. Pull. By this action, first, the free end portion 50f of the guide tape 50 is peeled off from the surface of the packaging sheet 20. Then, the first end edge portion 20rf of the packaging sheet 20 is pulled by the guide tape 50, and the end portion region 27 where the first end edge portion 20rf is joined is peeled off to open the sanitary napkin 1.

FIG. 7A is a view for explaining an operation when the absorbent article package 100 having no high-density portion of the packaging sheet is unsealed as a comparative example. Fig. 7B is a view for explaining an operation when the sanitary napkin 1 in an individual package state is opened in the present embodiment. 7A and 7B are schematic cross-sectional views showing a state in which the guide tape is pulled from the lateral direction in the absorbent article package having the packaging sheet made of non-woven fabric.

As described above, when the absorbent article package is opened, the following operation is performed, that is, the free end side of the guide tape is directed from the inner side in the thickness direction to the outer side and from the one side in the longitudinal direction to the other side. The drawing sheets are peeled off from each other in the thickness direction. In the case where such an operation is performed, the conventional absorbent article package 100 shown in Fig. 7A is pulled at the end of the longitudinal direction of the packaging sheet 120 if the free end portion 150f of the leader tape 150 is strongly pulled. The portion 120ef, which is bonded and fixed to the base end portion 150s of the guide tape 150, is peeled off from the packaging sheet 120 to cause the guide tape 150 to be detached from the packaging sheet 120.

Further, in the case where the packaging sheet 120 is formed by non-woven fabric, the surface of the non-woven fabric is formed with fine irregularities by complicated winding of a plurality of fibers, and if it is microscopic, the surface is rough. When the adhesive layer 155 is provided on such a surface, the area (contact area) of the contact portion where the adhesive layer forming the adhesive layer 155 is in contact with the non-woven fabric surface becomes small, and the adhesive (the adhesive layer 155) cannot be sufficiently fixed to the non-woven fabric. The surface becomes easy to peel off. As a result, the so-called [fiber detachment] in which the fibers on the surface of the packaging sheet 120 (non-woven fabric) are peeled off together with the adhesive layer 155, or the nonwoven fabric itself is broken, causes the guide tape 150 to be easily detached.

Further, as described in the above Patent Document 1, by performing the smoothing treatment on a part of the packaging sheet 120 in advance, it is possible to prevent the fiber from being detached in this region. However, conventionally, there has not been an example in which the smoothing process is performed up to the end portion 120ef of the packaging sheet 120 in the longitudinal direction. Therefore, at the end 120ef where the maximum force acts when the leader tape 150 is pulled, the peeling of the adhesive layer 155 is easily generated, and the peeling propagates along the longitudinal direction of the packaging sheet 120, and therefore, the result is as shown in Fig. 7A. The guide tape 150 becomes easily detached from the packaging sheet 120.

On the other hand, in the sanitary napkin 1 of the present embodiment, the high-density portion 25 is formed in the entire region of the packaging sheet 20 that overlaps with the base end portion 50s of the guide tape 50 in the thickness direction. 251c). In the high-density portion 25, the surface of the packaging sheet 20 is subjected to a compression treatment so that the fibers are pressed and fixed, and the unevenness of the surface of the nonwoven fabric is reduced to form a smooth state. Therefore, by providing the adhesive layer 55 at a position overlapping with the high-density portion 25, the area (contact area) of the portion where the adhesive is in contact with the surface of the nonwoven fabric can be increased, and the adhesion force by the adhesive layer 55 can be sufficiently enhanced. Further, since the high-density portion 25 itself has high strength, even if a force acts on the direction in which the base end portion 50s of the guide tape 50 is peeled off, it is less likely to cause breakage of the nonwoven fabric, fiber detachment, and the like.

In the sanitary napkin 1 of the present embodiment, the high-density portion 25 (the central high-density portion 251c) is formed in the longitudinal direction of the first end edge portion 20rf of the packaging sheet 20, unlike the conventional absorbent article package. Until 20ef. In other words, the first end edge portion 20rf of the packaging sheet 20 is a region having a predetermined width in the longitudinal direction from the end portion 20ef in a portion overlapping the base end portion 50s of the guide tape 50 in the thickness direction, and the density is higher. The predetermined density ρ20 is high and the thickness is thinner than the predetermined thickness t20. Therefore, as shown in FIG. 7B, at the end portion 20ef where the maximum force acts when the leader tape 50 is pulled, the peeling of the adhesive layer 55 is less likely to occur, and the guide tape 50 can be effectively prevented from being detached from the packaging sheet 20.

Further, the high-density portion 25 (central high-density portion 251c) formed in the first end edge portion 20rf of the packaging sheet 20 is formed in the lateral direction as compared with the base end portion 50s of the guide tape 50 as shown in FIG. The area of the wider area on both sides. In other words, the packaging sheet 20 is a region having a predetermined width toward the outside from both ends of the region overlapping the guide tape 50 in the lateral direction, and has a density higher than a predetermined density ρ20 and a thickness thinner than a predetermined thickness t20. Therefore, when the sanitary napkin 1 is manufactured, the position at which the base end portion 50s of the guide tape 50 is joined and fixed to the packaging sheet 20 is slightly shifted in the lateral direction, and the adhesive layer 55 of the proximal end portion 50s can be disposed at a high level. Since the density portion 25 is repeated, it is possible to suppress the joint strength of the guide tape 50 from becoming weak.

In the case where the sanitary napkin 1 in the individual packaging state is opened and the lead tape 50 is pulled, the packaging sheet 20 needs to be considered in addition to the force acting in the longitudinal direction (and the thickness direction) as illustrated in FIG. The force in the horizontal direction. Fig. 8 is a schematic perspective view showing an operation of pulling the leader tape 50 when the sanitary napkin 1 in an individual package state is unsealed. In the sanitary napkin 1 of the present embodiment, the guide tape 50 is fixed to a position substantially at the center in the lateral direction of the first end edge portion 20rf (end portion 20ef) of the packaging sheet 20. Therefore, when the free end portion 50 of the leader tape 50 is pulled when the opening operation of the sanitary napkin 1 is performed, as shown in Fig. 8, first, the center portion of the end portion 20ef of the packaging sheet 20 is pulled, and then, Gravity is gradually transmitted to both sides of the end portion 20ef of the packaging sheet 20 in the lateral direction. Therefore, in the case where the leader tape 50 has been pulled, the point at which both ends of the base end portion 50s of the guide tape 50 in the lateral direction intersect with the end portion 20ef of the packaging sheet 20, that is, the end point 50se, is packaged. The sheet 20 has a large force.

Therefore, in the packaging sheet 20, the width W251f in the lateral direction of the one end portion (that is, the end portion 20ef) of the one side in the longitudinal direction of the central high-density portion 251c which is overlapped with the base end portion 50s of the guide tape 50. The width W251b in the lateral direction is longer than the end portion on the other side in the longitudinal direction (see Fig. 5). As described above, the density of the high-density portion 25 (the central high-density portion 251c) is higher than the predetermined density ρ20, so that the strength of the non-woven fabric is high. Therefore, the width W251f is increased by the end portion 20ef on one side in the longitudinal direction of the central high-density portion 251c, and the region having high strength (that is, the high-density portion 25) is made wider, so that even At the end point 50se, when a large force acts on the lateral direction, it is also possible to easily suppress the fiber peeling of the nonwoven fabric or the breakage of the nonwoven fabric.

Further, the width W251b of the portion of the central high-density portion 251c having the narrowest width in the lateral direction is wider than the base end portion 50s of the guide tape 50 in the lateral direction as described above. Therefore, since the adhesive layer 55 of the proximal end portion 50s is disposed in the entire lateral direction and is disposed repeatedly with the central high-density portion 251c, even if the force acts on the lateral direction, the adhesive layer 55 is less likely to be peeled off. The possibility that the leader tape 50 is detached from the packaging sheet 20 is extremely low.

Further, in the sanitary napkin 1 in the individual packaging state, as shown in FIG. 6, the adhesive layer 55 of the guide tape 50 and the end portion following region 27 of the packaging sheet 20 are disposed at positions overlapping in the longitudinal direction (and the lateral direction). That is, the layer 55 and the end portion region 27 are repeatedly arranged alternately across the first end edge portion 20rf of the packaging sheet 20. In this case, when the high-density portion 25 (the central high-density portion 251c) is formed in the first end edge portion 20rf, the adhesive forming the adhesive layer 55 and the end portion-attached region 27 oozes toward the opposite side in the thickness direction of the nonwoven fabric. After that. On the other hand, in the sanitary napkin 1, the adhesive layer 55 and the end portion region 27 are repeatedly arranged in the high density portion 25 (the central high density portion 251c) having a high fiber density. Therefore, in the high-density portion 25, movement, bleeding, and the like of the adhesive in the thickness direction of the nonwoven fabric can be suppressed.

Moreover, the end portion following region 27 of the packaging sheet 20 is disposed at a position overlapping the first high-density region 251 formed along the lateral direction in the longitudinal direction. That is, the adhesive forming the end portion region 27 is applied to the range of the packaging sheet 20 that overlaps with the first high-density region 251. Thereby, it is possible to prevent the adhesive forming the end portion region 27 in the entire region of the first high-density region 251 from oozing out toward the upper side (the surface side of the product) in the thickness direction of the nonwoven fabric. In other words, not only the central portion (central high-density portion 251c) in the lateral direction of the first end edge portion 20rf of the packaging sheet 20 but also the regions on both sides thereof can suppress the bleeding of the adhesive, and the individual packaging can be suppressed. The outer side surface of the sanitary napkin 1 (package sheet 20) is sticky.

Further, as shown in FIG. 5, the first high-density region 251 is formed by a central high-density portion 251c provided at the center in the lateral direction and a plurality of bilateral high-density portions 251s provided on both sides thereof. A predetermined gap is provided between the density portion 251c and the both side high-density portions 251s or between the respective high-density portions 251s and 251s on both sides. That is, in the first high-density region 251, a portion having a predetermined density ρ20 and a predetermined thickness t20 (a portion where the high-density portion 25 is not formed) is higher than a predetermined density ρ20 and a thickness thinner than a predetermined thickness t20. The portions (the high density portion 25) are arranged adjacent to each other in the lateral direction. In other words, in the first end edge portion 20rf of the packaging sheet 20, a portion where the fibers are easily extended (a portion where the high-density portion 25 is not formed) and a portion where the fibers are not easily stretched (the high-density portion 25) are disposed adjacent to each other. With such a configuration, it is possible to easily perform the operation of unsealing the sanitary napkin 1 in an individual package state.

For example, as shown in FIG. 8, in the case where the leader tape 50 is pulled, the force of pulling the leader tape 50 is transmitted along the first end edge portion 20rf (end portion 20ef) of the packaging sheet 20 toward the lateral sides. . At this time, when the high-density portion 25 is formed in the entire first edge portion 20rf, the force for pulling the leader tape 50 acts on the ends of the guide tape 50 (base end portion 50s) in the lateral direction as the impact force. Point 50se, resulting in the end point 50se, then the layer 55 becomes easy to peel off. On the other hand, in the present embodiment, a portion where the fibers are easily extended is provided at a position in the lateral direction of the first end edge portion 20rf, so that the portion where the fibers are easily extended is force-dispersed in order to extend the fibers. Therefore, at the end points 50se at both ends of the guide belt 50 (base end portion 50s) in the lateral direction, the force is less likely to concentrate, and the guide belt 50 can be more easily prevented from being detached from the packaging sheet 20.

Further, in the first end edge portion 20rf, the ratio of the portion in which the high-density portion 25 is formed is smaller than the ratio in which the portion of the high-density portion 25 is not formed, that is, the area in which the portion of the high-density portion 25 is formed. In the case of being relatively small, there is a problem that the problems such as the above-mentioned adhesive oozing and the damage of the nonwoven fabric cannot be sufficiently suppressed. On the other hand, in the packaging sheet 20 of the present embodiment, the sum of the areas of the first edge portion 20rf having a density higher than a predetermined density ρ20 and having a thickness thinner than a predetermined thickness t20 is a predetermined density ρ20 and The sum of the areas of the portions of the predetermined thickness t20 is large. Therefore, it is easy to suppress bleeding of the adhesive agent, damage of the nonwoven fabric, and the like in the entire region of the first end edge portion 20rf.

In addition, the first high-density region 251 formed along the first end edge portion 20rf is formed from the side end portion 20rs on one side in the lateral direction of the packaging sheet 20 to the side end portion 20rs on the other side. Therefore, the both high-density portions 251s constituting the first high-density region 251 are overlapped with at least a part of the sealing region 29 of the packaging sheet 20 (see FIG. 5). Thereby, in the repeated portion, the strength of the nonwoven fabric becomes high, and when the sealing region 29 is peeled off, it is possible to easily suppress the breakage of the nonwoven fabric in the sealing region 29. For example, as shown in Fig. 8, when the sanitary napkin 1 in the individually packaged state is unsealed, when the force of pulling the leader tape 50 has been transmitted to the sealing region 29, it is repeated in the sealing region 29 with the high-density portions 251s on both sides. The strength of the portion is high, so that even if a large force acts on the portion, the packaging sheet is not easily broken.

Figure 9 is a schematic plan view of the sanitary napkin 1 in an individually wrapped state that has been folded. FIG. 10A is a view for explaining an operation when the absorbent article package 500 having no high-density portion in the packaging sheet is unsealed as a comparative example. Fig. 10B is a view for explaining an operation when the sanitary napkin 1 in an individual package state is opened in the present embodiment. 10A and 10B are schematic cross-sectional views showing a state in which the guide tape is pulled from the lateral direction in the absorbent article package having the packaging sheet made of non-woven fabric.

As described above, when the absorbent article package is opened, the following operation is performed, that is, the free end side of the guide tape is directed from the inner side in the thickness direction to the outer side and from the one side in the longitudinal direction to the other side. The drawing sheets are peeled off from each other in the thickness direction. Specifically, the free end portion 550f of the guide tape 550 is pulled, and the adhesive layer 555 which is joined and fixed to the surface of the packaging sheet 520 by the free end portion 550f is peeled off from the packaging sheet 520.

Here, in the case where the packaging sheet 520 is formed by non-woven fabric, the surface of the non-woven fabric is formed with fine irregularities by complicated winding of a plurality of fibers, and if it is microscopic, the surface is rough. When the adhesive layer 555 joined to the surface of such a nonwoven fabric is peeled off, a part of the fibers constituting the surface of the nonwoven fabric is peeled off from the surface of the nonwoven fabric together with the adhesive layer 555. As a result, as shown in Fig. 10A, so-called [fiber detachment] or damage of the nonwoven fabric itself may occur on the surface of the nonwoven fabric. Further, the peeled fibers are attached to the adhesive layer 555 at the free end portion 550f of the guide tape 550, resulting in loss of adhesion of the layer 555 at the free end portion 550f.

On the other hand, in the sanitary napkin 1 of the present embodiment, the fourth high-density region 254 is formed in a region of the packaging sheet 20 that overlaps with the free end portion 50f of the guide tape 50 in the thickness direction. That is, the packaging sheet 20 is formed in at least a part of the region of the free end portion 50f of the adhesive guiding tape 50, and is formed with a high-density portion 25 having a density higher than a predetermined density ρ20 and having a thickness thinner than a predetermined thickness t20. In the high-density portion 25, the surface of the packaging sheet 20 is subjected to a compression treatment so that the fibers are pressed and fixed, and the unevenness of the surface of the nonwoven fabric is reduced to form a smooth state. Therefore, in the high-density portion 25, the strength of the non-woven fabric is high, and the fibers are not easily peeled off. Therefore, even if the operation of peeling the free end portion 50f of the guide tape 50 from the surface of the packaging sheet 20 is performed, as shown in Fig. 10B, the surface of the packaging sheet 20 (the fourth high-density region 254) is less likely to cause fiber peeling and breakage. Wait. Further, since the adhered fibers can be prevented from adhering to the adhesive layer 55 of the leader tape 50, the adhesion of the adhesive layer 55 can be easily maintained. Thereby, even after the sanitary napkin 1 is unfolded, the function of the packaging sheet 20 is hard to be damaged, and the packaging sheet 20 can be reused.

FIG. 11 is a view for explaining an example of a method of recycling the packaging sheet 20. The sanitary napkin 1 can wrap the used absorbent article 10 with the packaging sheet 20 after using the absorbent article 10, and as shown in FIG. 11, the packaging sheet 20 is formed to the outside in the longitudinal direction (length). In the state of being rounded, the guide tape 50 is used for fixing, whereby the used absorbent article can be discarded as a compact shape without being exposed to the outside. That is, in the case of the use state as shown in FIG. 11, it is desirable that the packaging sheet 20 has a function of packaging the absorbent article 10 even when the sanitary napkin 1 is discarded.

In the present embodiment, as described above, even when the sanitary napkin 1 is unfolded, the operation of peeling off the free end portion 50f of the guide tape 50 adhered to the surface of the packaging sheet 20 can be suppressed, and the packaging sheet 20 can be prevented from being damaged or The adhesion of the guide tape 50 (following layer 55) is lost. Therefore, when the sanitary napkin 1 after use is discarded, as shown in FIG. 11, the absorbent article 10 can be wrapped with the packaging sheet 20 and the packaging state can be fixed using the guide tape 50.

Further, in the packaging sheet 20, the fourth high-density region 254 is formed along the lateral direction. That is, the packaging sheet 20 is a portion wider in the lateral direction than the region of the free end portion 50f of the adhesive guiding tape 50, and has a portion having a density higher than a predetermined density ρ20 and a thickness thinner than a predetermined thickness t20. Therefore, when the sanitary napkin 1 is folded to form an individual packaging state as shown in Fig. 1, even if the position of the free end portion 50f of the guide tape 50 is offset in the lateral direction, the free end can be used. The portion 50f is easily disposed at a position overlapping with the high density portion 25. Thereby, it is easier to suppress the damage of the packaging sheet 20 or the adhesiveness of the adhesive layer 55 of the guide tape 50, etc., by peeling off the adhesive tape 50 which adhered.

Further, in the sanitary napkin 1 in the individual packaging state, as shown in FIG. 6, the end portion following region 27 of the packaging sheet 20 is disposed at a position overlapping the fourth high-density region 254 in the longitudinal direction (and the lateral direction). When the fourth high-density region 254 (high-density portion 25) is not formed in the packaging sheet 20, when the end portion region 27 is peeled off when the sanitary napkin 1 is opened, the fibers of the nonwoven fabric are peeled off together. On the other hand, in the present embodiment, the end portion region 27 of the packaging sheet 20 is overlapped with the high-density portion 25 (fourth high-density region 254) having a density higher than a predetermined density ρ20 and having a thickness thinner than a predetermined thickness t20. As described above, in the high-density portion 25, the fibers are pressed and fixed, and the surface of the non-woven fabric is formed into a smooth shape. Therefore, the strength of the non-woven fabric is high, and the fibers are less likely to be peeled off. Therefore, when the end portion region 27 is peeled off, it is possible to prevent the fiber from being detached, the nonwoven fabric from being damaged, or the like.

Further, by repeating the end portion region 27 and the fourth high density region 254, the adhesive forming the end portion region 27 is less likely to penetrate into the nonwoven fabric. That is, in the portion of the non-woven fabric surface where the high-density portion 25 is formed and the density is high, it is possible to suppress the bleeding of the adhesive agent to the opposite side of the nonwoven fabric. Therefore, the problem that the adhesive of the end portion region 27 oozes out to the back side of the packaging sheet 20 and adheres to the absorbent article 10 or the like is less likely to occur.

Further, in the operation of unwinding the sanitary napkin 1 from the individual packaging state, the packaging sheet 20 can be smoothly peeled off from the absorbent article 10 by pulling the leader tape 50. Figure 12 is a schematic plan view for explaining the arrangement of the package sheet joint portion 132.

In the packaging sheet 20 of the present embodiment, a plurality of packaging sheet joining portions 132 are arranged side by side in the longitudinal direction. In FIG. 12, the three package sheet joining portions 132a, 132b, and 132c are arranged side by side from the front side in the longitudinal direction toward the rear side in the center portion in the lateral direction. Further, the packaging sheet joint portion 132a overlaps the second high-density region 252 in the longitudinal direction. Similarly, the packaging sheet joint portion 132b overlaps the third high-density region 253 in the longitudinal direction, and the packaging sheet joint portion 132c overlaps the fourth high-density region 254 in the longitudinal direction. Therefore, the joint strength between the packaging sheet 20 and the separator 30 can be improved in the portion where the respective packaging sheet joint portion 132 overlaps with the high density portion 25 constituting the high-density regions 252 to 254. Thereby, when the leader tape 50 has been pulled, it is difficult to cause the problem that only the package sheet 20 is peeled off from the separator 30 and the separator 30 remains on the side of the absorbent article 10. In addition, the shape, size, and the like of the packaging sheet joint portions 132a, 132b, and 132c are not limited to those shown in FIG. 12, and may be appropriately changed in accordance with the size, shape, and the like of the packaging sheet 20.

Moreover, by repeating the packaging sheet joint portion 132 and the high-density portion 25 (high-density regions 252 to 254), it is possible to more effectively suppress the bleeding of the adhesive forming the packaging sheet joint portion 132 to the opposite side surface of the packaging sheet 20.

Further, in the sanitary napkin 1 of the present embodiment, the high-density portion 25 (the first high-density region) is formed in the region of the first end edge portion 20rf of the packaging sheet 20 in the region where the base end portion 50s of the guide tape 50 is disposed. 251) (Refer to Figure 3). Therefore, in this region, the joint strength of the base end portion 50s of the guide tape 50 to the packaging sheet 20 becomes high, and when the boot tape 50 is pulled while the sanitary napkin 1 is opened, the guide tape 50 can be suppressed from the packaging sheet 20 Get rid of.

In particular, a central high-density portion 251c having a larger area than the other high-density portions 25 is formed in the central portion in the lateral direction of the first high-density region 251, and the base end portion 50s of the guide tape 50 is formed in the central high-density portion 251c. Repeated throughout the region. That is, the first end edge portion 20rf of the packaging sheet 120 is a region having a predetermined width in the longitudinal direction from the end portion 20ef in a portion overlapping the base end portion 50s of the guide tape 50 in the thickness direction, and the density It is higher than the predetermined density ρ20 and thinner than the predetermined thickness t20. Thereby, the end portion 20ef of the packaging sheet which the maximum force acts when the leader tape 50 is pulled is pulled, the peeling of the adhesive layer 55 is less likely to occur, and the guiding tape 50 can be effectively prevented from being detached from the packaging sheet 20.

Further, the high-density portion 25 (central high-density portion 251c) formed in the first end edge portion 20rf of the packaging sheet 20 is formed in the lateral direction as compared with the base end portion 50s of the guide tape 50 as shown in FIG. The area on both sides has a wider area. In other words, the packaging sheet 20 is a region having a predetermined width toward the outside from both ends of the region overlapping the guide tape 50 in the lateral direction, and has a density higher than a predetermined density ρ20 and a thickness thinner than a predetermined thickness t20. Therefore, since the adhesive layer 55 of the proximal end portion 50s is disposed in the entire lateral direction and is disposed repeatedly with the central high-density portion 251c, even when the guide tape 50 is pulled, the force acts on the lateral direction. In other cases, the layer 55 is less likely to be peeled off, and the packaging sheet 20 can be prevented from being damaged at both side portions of the leader tape 50. Further, even when the sanitary napkin 1 is manufactured, the position where the base end portion 50s of the guide tape 50 is joined and fixed to the packaging sheet 20 is slightly shifted in the lateral direction, and the adhesive layer 55 of the proximal end portion 50s is disposed in the same manner. Since the position of the high-density portion 25 is repeated, it is easy to suppress the joint strength of the guide tape 50 from becoming weak.

Further, in the sanitary napkin 1 in the individual packaging state, as shown in FIG. 6, the adhesive layer 55 of the guide tape 50 and the end portion following region 27 of the packaging sheet 20 are disposed at positions overlapping in the longitudinal direction (and the lateral direction). That is, the layer 55 and the end portion region 27 are repeatedly arranged alternately across the first end edge portion 20rf of the packaging sheet 20. In this case, when the high-density portion 25 (the central high-density portion 251c) is formed in the first end edge portion 20rf, the adhesive forming the adhesive layer 55 and the end portion-attached region 27 oozes toward the opposite side in the thickness direction of the nonwoven fabric. After that. On the other hand, in the sanitary napkin 1, the adhesive layer 55 and the end portion region 27 are repeatedly arranged in the high density portion 25 (the central high density portion 251c) having a high fiber density. Therefore, in the high-density portion 25, the adhesive agent is less likely to bleed, and the outer surface of the sanitary napkin 1 (package sheet 20) in the individual package state can be suppressed from sticking.

Further, as shown in FIG. 3, the first crease F1 of the packaging sheet 20 is placed at a position overlapping the fourth high-density region 254 in the longitudinal direction (longitudinal direction). The first crease F1 is a base point at which the first crease 1 is bent when the sanitary napkin 1 is folded, and the tampon 1 needs to be clearly provided with a crease in the first crease F1 in order to maintain the individual packaging state. However, in the case where the packaging sheet 20 is formed of a soft non-woven fabric, even if a crease is temporarily formed, it is easy to return to the original shape as time passes. That is, it is not easy to impart [creases] to the nonwoven fabric.

Therefore, in the packaging sheet 20 of the present embodiment, the density is higher than the predetermined density ρ20 and the thickness is thinner than the predetermined thickness t20 in the region overlapping the first crease F1 in the longitudinal direction. Since the non-woven fabric is thinned, it is easy to bend the non-woven fabric in this area, and it is difficult to return to the original shape as long as the bent portion is not. Thereby, when the absorbent article is folded, the packaging sheet 20 is easily bent at the first crease F1, and the individual packaging state can be easily maintained. Moreover, since the density of the non-woven fabric of the portion in which the first crease F1 is provided is increased, the sanitary napkin 1 in the individual packaging state is less likely to cause damage such as breakage of the packaging sheet 20 along the first crease F1. As a result, since the individual packaging state is less likely to collapse, the user can safely take the action of putting the sanitary napkin 1 in the backpack and carrying it.

=== Second Embodiment === <Structure of the absorbent article package> In the second embodiment, the sanitary product including the flap portion will be described as an example of the absorbent article package (individual package). Cotton 2 (hereinafter also referred to as [sanitary cotton 2]). Fig. 13 is a schematic plan view showing the sanitary napkin 2 in a state in which it has been unfolded from the skin side. The shape of the sanitary napkin 2 of the second embodiment is different from that of the sanitary napkin 1 of the first embodiment. Further, the packaging sheet 20 of the sanitary napkin 2 is provided with a flap portion separator 35 which will be described later. The other basic structure of the sanitary napkin 2 is substantially the same as that of the sanitary napkin 1 of the first embodiment.

In the sanitary napkin 2, the absorbent article 10 has a flap portion 15. The flap portion 15 is formed in the vicinity of the center portion in the longitudinal direction of the absorbent article 10, that is, between the end portion on one side in the longitudinal direction of the product and the end portion on the other side, by the top sheet 12 and the back sheet 13 At least one of them is formed to extend outward from both end portions in the lateral direction. In the non-skin side surface in the thickness direction of the flap portion 15, a flap adhesive portion 151 to which an adhesive such as a hot melt adhesive is applied is provided in the same manner as the main body adhesive portion 131. When the absorbent article 10 is used, the body adhesive portion 131 of the absorbent article 10 is adhered to the inner side (skin side) of the crotch portion of the undergarment, and then the flap portion 15 is bent toward the non-skin side to adhere the flap adhering portion 151. On the outside of the lower part of the underwear (non-skin side). Thereby, the absorbent article 10 is fixed by sandwiching the body adhesive portion 131 and the flap adhering portion 151 in the crotch portion of the undergarment, and it is easy to suppress the positional deviation or the like when the absorbent article 10 is worn.

In the sanitary napkin 2, the second edge portion 20rb on the rear side in the longitudinal direction of the packaging sheet 20 protrudes toward the rear side (the outer side in the longitudinal direction) of the absorbent article 10 as shown in FIG. That is, the dimension of the packaging sheet 20 in the longitudinal direction is longer than the dimension of the absorbent article 10 in the longitudinal direction. Further, in the second edge portion 20rb, a fifth high-density region 255 (also referred to as a "second edge portion high-density region") is formed by a plurality of high-density portions 25 arranged in the lateral direction. In the high-density portion 25 of the non-woven fabric, by performing the same compression treatment as in the first embodiment, the density is higher than the predetermined density ρ20 and the thickness is thinner than the predetermined thickness t20.

Further, the blade separator joint portion 135 (also referred to as "finor body adhesion portion") is formed by applying an adhesive such as a hot melt adhesive to the skin side in the thickness direction of the second end portion 20rb. . The flap separator 35 is joined and fixed to the skin side in the thickness direction of the packaging sheet 20 via the flap separator joint portion 135 (flap body adhering portion). The flap separator 35 is a sheet member which is peeled off by using a resin or the like on the skin side surface similarly to the separator 30.

Fig. 14 is a schematic plan view showing a state in which the first crease F1 is folded in the longitudinal direction in the expanded state. Figure 15 is a schematic cross-sectional view showing a C-C section in Figure 14.

When the sanitary napkin 2 is in an individual packaging state as shown in FIG. 1, first, the flap portions 15 projecting toward both sides in the lateral direction of the absorbent article 10 are folded back toward the inner side in the lateral direction. In FIG. 14, the flap portions 15 and 15 on both sides in the lateral direction are respectively folded inward from the outer side in the lateral direction, and are formed as the first flap crease FW1 which is disposed in the longitudinal direction at a predetermined position in the lateral direction. The second flap crease FW2 is a base point, and the skin side surface of the absorbent article 10 is inside. In this state, the flap adhering portion 151 is exposed on the upper side in the thickness direction.

Then, the packaging sheet 20 and the absorbent article 10 (and the separator 30) are bent in the longitudinal direction with the first crease F1 as a base point, and the skin side surface of the absorbent article 10 becomes the inside. In other words, the second end edge portion 20rb (end portion 20eb) of the packaging sheet 20 is folded back toward the inside from the outer side in the longitudinal direction (longitudinal direction) with the first crease F1 as a base point. At this time, the surface (the lower surface in FIG. 15) which has been subjected to the peeling process in the flap separator 35 joined to the second end edge portion 20rb is detachably adhered to the flap adhering portion 151. Thereby, before the use of the absorbent article 10, adhesion of the adhesive forming the flap adhesive portion 151 to the packaging sheet 20 can be suppressed, and the flap adhesive portion 151 can be protected.

In the sanitary napkin 2 of the second embodiment, the fin separator joint portion 135 (the fin main body adhesion portion) is provided in the longitudinal direction and the lateral direction and the fifth high-density region 255 (the second end portion high-density region) ) Repeated position. As described above, in the high-density portion 25 (the fifth high-density region 255), the fibers of the non-woven fabric are pressed and fixed, the fine unevenness is reduced, and the surface is formed into a smooth state. Therefore, the contact area of the adhesive in contact with the surface of the nonwoven fabric becomes larger than the area where the high-density portion 25 is not formed, and the bonding strength between the fin separator joint portion 135 (the fin body adhering portion) and the packaging sheet 20 is strong. Thereby, when the sanitary napkin 2 in the individual package state is unsealed, the flap separator 35 can be prevented from being detached from the packaging sheet 20 by the peeling of the flap separator joint portion 135 (the flap body adhering portion). The sheet separator 35 remains on the side of the absorbent article 10.

Further, the fin separator joint portion 135 (the fin body adhering portion) is overlapped with the fifth high-density region 255 (the second end edge portion high-density region) so that the vane separator joint portion 135 is formed in this region. The adhesive does not easily ooze out toward the opposite side of the thickness direction of the packaging sheet 20 (non-woven fabric). Thereby, the surface of the packaging sheet 2 can be suppressed from sticking.
