Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[Overall composition of napkin]
The absorbent article 1 shown in FIG. 1 includes a main body M, a pair of wing portions W, and a leak-proof groove 9. The absorbent article 1 is configured as a sanitary napkin and is hereinafter referred to as a napkin 1.
The napkin 1 has a vertical direction X corresponding to the front-rear direction of the wearer and a horizontal direction Y corresponding to the left-right direction of the wearer and orthogonal to the vertical direction X. Further, the napkin 1 has a thickness direction Z orthogonal to both the vertical direction X and the horizontal direction Y. In the present specification, regarding the thickness direction Z of the napkin 1, the side close to the wearer's skin may be the upper or skin side, and the side close to the clothes may be the lower or non-skin side when worn.

The main body M extends along the vertical direction X and is fixed to the inner surface of the wearer's clothing when worn. The main body M has an absorber 11 described later, and has a function of absorbing liquid excrement such as menstrual blood of the wearer.
The wing portion W is configured so as to greatly project outward from the main body M in the lateral direction Y.
The napkin 1 does not have to have a wing portion W.

The leak-proof groove 9 is a linear groove formed on the surface sheet 12 side of the main body M, which will be described later, and is formed by integrally compressing the surface sheet 12 and the absorber 11 in the thickness direction Z. In the example shown in FIG. 1, the leak-proof groove 9 has a circumferential groove that orbits the peripheral edge of the main body M, and a pair of vertical grooves that are located outside the circumferential Y in the lateral direction. The "circulation" is a form in which the leak-proof groove 9 extends continuously and orbits, and a shape in which a plurality of squeezed portions are intermittently arranged and can be regarded as one groove as a whole. It is a meaning that includes both forms and. The leak-proof groove 9 is not limited to the configuration shown in FIG.

As shown in FIG. 2, the napkin 1 includes an absorber 11, a front surface sheet 12, a back surface sheet 13, and a pair of side sheets 14. In the main body M, the napkin 1 has a structure in which the front surface sheet 12, the absorber 11, and the back surface sheet 13 are laminated in the thickness direction Z. These configurations are appropriately joined and integrated by, for example, joining with an adhesive S, a heat seal, or the like, and pressing with a leak-proof groove 9.

The surface sheet 12 is configured as a liquid-permeable sheet material, and is arranged above the thickness direction Z of the absorber 11.
The surface sheet 12 has, for example, a plurality of convex portions 12a projecting upward. The convex portion 12a may have a solid structure in which fibers are also distributed inside, or a hollow structure in which fibers are hardly present inside. The convex portion 12a can reduce the contact area between the wearer's skin and the surface sheet 12 when worn, enhance breathability, and reduce discomfort.

The back sheet 13 is arranged below the thickness direction Z of the absorber 11. The back surface sheet 13 is joined to the front surface sheet 12 and the side sheet 14 by, for example, an adhesive S, a heat seal, or the like at a peripheral edge portion. The back sheet 13 is also bonded to the absorber 11 by the adhesive S.
The back surface sheet 13 is formed of, for example, a sheet material having functions such as poor liquid permeability, water vapor permeability, and water repellency. As the sheet material, for example, a film made of a thermoplastic resin, a laminate of the film and a non-woven fabric, or the like can be used.

A slip stopper (not shown) is arranged on the outer surface of the back sheet 13 of the main body M and the wing portion W. The anti-slip material fixes the napkin 1 to the clothes and also fixes the napkin 1 to the exterior material 16 described later so as to be peelable. The anti-slip material is formed, for example, by applying an adhesive to the back surface sheet 13 in a predetermined pattern. As the pressure-sensitive adhesive used for the slip stopper, a rubber-based, olefin-based, ethylene-vinyl acetate (EVA) -based hot melt pressure-sensitive adhesive is preferably used.

The pair of side sheets 14 are arranged on the periphery of the surface sheet 12 in the lateral direction Y, and face each other in the lateral direction Y with the surface sheet 12 interposed therebetween. As the material of the side sheet 14, a sheet material having a lower hydrophilicity than the surface sheet 12 is preferable, and specifically, a non-woven fabric, a film material, and a laminated structure of the non-woven fabric and the film material having a lower hydrophilicity than the surface sheet 12 The sheet can be mentioned.

As shown in FIG. 1, the absorber 11 has a front end portion 11a and a rear end portion 11b, and extends in the longitudinal direction X from the front end portion 11a toward the rear end portion 11b. The front end 11a is located ventral to the wearer's excretion when worn, and the rear end 11b is located dorsal to the wearer's excretion when worn. From another point of view, the front end portion 11a is located in the second folding region R2 described later, and the rear end portion 11b is located in the first folding region R1 described later.
As shown in FIG. 2, the absorber 11 is arranged between the front surface sheet 12 and the back surface sheet 13. The absorber 11 absorbs the liquid excrement from the skin-facing surface 11c on the surface sheet 12 side and diffuses it inside to hold the excrement.
The absorber 11 has an absorbent core 6 and a core wrap sheet 7.

The absorbent core 6 has, for example, a fiber aggregate composed of hydrophilic fibers such as pulp fibers and a water-absorbing polymer held by the fiber aggregate. As a result, the liquid holding power of the absorbent core 6 can be increased.

The core wrap sheet 7 covers the absorbent core 6 and is formed of, for example, a thin soft paper such as tissue paper or a liquid-permeable non-woven fabric. The surface of the core wrap sheet 7 on the front surface sheet 12 side constitutes the skin-facing surface 11c of the absorber 11, and the surface on the back surface sheet 13 side constitutes the non-skin-facing surface 11d of the absorber 11. The skin facing surface 11c is adhered to the front surface sheet 12 with an adhesive S such as a hot melt adhesive, and the non-skin facing surface 11d is adhered to the back surface sheet 13 with an adhesive S.

[Compression area configuration]
As shown in FIG. 1, the absorber 11 has a first squeezed region 2 and a second squeezed region 4. The first squeezed region 2 is located in the first folded region R1 described later, for example, the rear end portion is located in the rear end portion 11b of the absorber 11. The second squeezed region 4 is located in the second folded region R2, which will be described later, and for example, the front end portion is located in the front end portion 11a of the absorber 11.

As shown in FIG. 2, the first squeezed region 2 and the second squeezed region 4 are formed by being compressed in the thickness direction Z of the absorber 11. Specifically, the first squeezing region 2 and the second squeezing region 4 each have a plurality of linear squeezing grooves 3.
The squeeze groove 3 is formed by compressing the absorber 11 in which the absorbent core 6 is covered with the core wrap sheet 7 in the thickness direction Z. That is, in the squeeze groove 3, only the absorbent core 6 and the core wrap sheet 7 of the absorber 11 are integrally recessed, and the surface sheet 12 is not compressed. In the example shown in FIG. 2, the squeezing groove 3 is compressed downward in the Z-axis direction from the skin facing surface 11c, and is also compressed upward in the Z-axis direction from the non-skin facing surface 11d.
The "linear" in the squeeze groove 3 is not limited to a linear aspect in a plan view, and includes a curved aspect. The phrase "extending in the vertical direction X" is not limited to a mode completely parallel to the vertical direction X, and may extend from the front to the rear. Further, each line in the pressing groove 3 may be a continuous line or a broken line, but in the present embodiment, it is composed of continuous lines.
Although FIG. 2 shows a cross section of the first squeezed region 2, the cross section of the second squeezed region 4 is similarly configured.

As shown in FIG. 2, the first squeezing region 2 and the second squeezing region 4 are configured to be consolidated and recessed as a whole by being compressed in the squeezing groove 3. As a result, in the first squeezed region 2 and the second squeezed region 4, a step and a difference in rigidity are generated between the first squeezed region 2 and the second squeezed region 4, which contributes to the improvement of the openability when the package 10 described later is constructed. Hereinafter, the configuration of the package 10 will be described.

[Package composition]
In the package 10 shown in FIGS. 1, 3 and 4, the above-mentioned napkin 1 is folded in the vertical direction X together with the exterior material 16 along two folding lines L1 and L2 (see FIG. 1) extending in the horizontal direction Y, and individually. It is packaged in. Note that FIG. 1 shows a package 10 in which the napkin 1 is stretched on an XY plane before folding and after opening.

The exterior material 16 is a sheet material that forms the outer surface of the package 10. In the example shown in FIG. 1, a rectangular shape that is larger than the area of the napkin 1 and long in the vertical direction X in a plan view from the thickness direction Z. It is composed of.
As the exterior material 16, various materials conventionally used as the exterior material of the absorbent article can be used without particular limitation, and for example, a resin film, a non-woven fabric, paper, or the like can be used. Such an exterior material 16 is generally less rigid than the absorber 11, and can be easily bent into a shape along the napkin 1.
Hereinafter, the process of folding the napkin 1 together with the exterior material 16 as shown in FIGS. 3 and 4 will be described.

First, as shown in FIG. 1, the napkin 1 is removably arranged at substantially the center of the exterior material 16 via a slip stopper. As a result, a laminated body of the napkin 1 and the exterior material 16 is obtained. At this time, it is preferable that the pair of wing portions W of the napkin 1 are bent toward the surface sheet 12 side (skin facing surface side) along both side portions along the vertical direction X of the main body M. Further, when the anti-slip material is formed on the wing portion W, it is preferable that the anti-slip material of the bent wing portion W is covered with the release sheet.

As shown in FIG. 1, in the laminated body of the napkin 1 and the exterior material 16, the first fold line L1 arranged on the rear side of the napkin 1 and the second fold line L2 arranged on the front side of the napkin 1 And are placed. More specifically, the first folding line L1 is arranged behind the wing portion W (on the back side of the wearer). The second fold line L2 is arranged in front of the wing portion W (ventral side of the wearer). The first fold line L1 and the second fold line L2 are virtual lines that serve as folding axes when the package 10 is folded.

The package 10 is divided by a first fold line L1 and includes a first fold region R1 including the rear end portion 11b of the absorber 11, and a second fold region R1 is partitioned by a second fold line L2 and includes a front end portion 11a of the absorber 11. It includes a region R2 and a third fold region R3 located between the first fold region R1 and the second fold region R2. In the present embodiment, the rear end portion 11b is also the "vertical direction X one end portion", and the front end portion 11a is also the "vertical direction X other end portion".
The first folding region R1 is an region of the napkin 1 including a rear region located on the dorsal side of the wearer's excretory portion when worn. The second folded region R2 is an region of the napkin 1 including an anterior region located ventral to the wearer's excretory portion when worn. The third folding region R3 is an region of the napkin 1 including an excretion portion facing region facing the wearer's excretion portion when worn.

The outermost end of the first folding region R1 in the vertical direction X is referred to as the first vertical end E11. The first vertical end portion E11 is composed of the exterior material 16 in the example of FIG. 1, but when the napkin 1 protrudes from the exterior material 16, it may be composed of the rear end portion of the napkin 1.
Similarly, the outermost end of the second folding region R2 in the vertical direction X is referred to as the second vertical end E21. The second longitudinal end E21 is typically composed of an exterior material 16.

From the state shown in FIG. 1, the first folding area R1 is folded on the third folding area R3 with the first folding line L1 as the folding axis. Specifically, the surface sheet 12 of the first folding region R1 is superposed on the surface sheet 12 of the third folding region R3.

Next, the second folding region R2 is folded so as to be further folded on the first folding region R1 folded on the third folding region R3 with the second folding line L2 as the folding axis. Specifically, the surface sheet 12 of the second folding region R2 is superposed on the exterior material 16 of the first folding region R1. As a result, the napkin 1 is folded in three in the vertical direction X to form the package 10 shown in FIGS. 3 and 4.

As shown in FIG. 4, the package 10 has a configuration in which the third folding region R3, the first folding region R1 and the second folding region R2 are laminated in this order. The outer surface of the package 10 is covered with the exterior material 16. The upper surface of the package 10 is composed of an exterior material 16 of the second folding region R2 and an exterior material 16 of the first folding region R1 exposed from the second folding region R2. The lower surface of the package 10 is composed of the exterior material 16 of the third folding region R3.

As shown in FIGS. 3 and 4, the end portion in the vertical direction X of the package 10 bent by the first folding line L1 between the first folding region R1 and the third folding region R3 is the first folding end portion. It is called RE1. The end portion of the package 10 folded by the second folding line L2 between the second folding region R2 and the third folding region R3 in the vertical direction X is referred to as a second folding end portion RE2.
The "upper" in the package 10 means the side on which the second folding region R2 is arranged in the thickness direction Z, and the "lower" in the packaging 10 means the side in which the third folding region R3 is arranged in the thickness direction Z. Refers to the side to be done.

Further, the package 10 has a tab tape T and a side sealing portion F as a configuration for maintaining the folded shape.
As shown in FIG. 3, the side sealing portion F is formed on the side edge of the exterior material 16 extending outward in the lateral direction Y from the napkin 1, and is joined by a known joining method such as heat embossing. Will be done.
The tab tape T seals the second vertical end portion E21 of the second folding region R2 and the exterior material 16 of the first folding region R1.

As shown in FIG. 3, the tab tape T has a fixing portion T1 and a protruding portion T2.
The fixing portion T1 is fixed to the exterior material 16 of the second folding region R2. The fixing portion T1 is fixed to the second longitudinal end portion E21 with, for example, a hot melt adhesive.
The protruding portion T2 projects outward from the fixed portion T1 to the second folding region R2, and is detachably adhered to the exterior material 16 of the first folding region R1. The protruding portion T2 includes an adhesive region T3 including an adhesive surface and a non-adhesive region T4 having no adhesiveness. An adhesive is applied to the adhesive surface of the adhesive region T3. The non-adhesive region T4 constitutes a free end portion of the protruding portion T2, and for example, the adhesive surfaces are folded over and have no adhesive surface on the outer surface. In the package 10, the non-adhesive region T4 stays inside the first folding region R1 in the vertical direction X with respect to the boundary side end with the third folding region R3, and the tab tape T is rolled up during storage. Problems such as opening the package without permission are suppressed.

When the package 10 is opened, the tab tape T is lifted upward by the user of the napkin 1 having the protruding portion T2 picked. Along with this, the second vertical end portion E21 to which the tab tape T is fixed is also rolled up. As a result, when tension is applied to the exterior material 16 from the fixed portion T1 of the lifted tab tape T toward the side sealing portion F, the sealing of the side sealing portion F cannot be maintained. The side sealing portion F on the second vertical end portion E21 side is opened. Then, by opening the second folding region R2 in the vertical direction X with the second folding line L2 as the axis, the side sealing portion F sequentially moves from the second vertical end E21 side toward the second folding end RE2. It is opened and the second folding area R2 side is opened.
After that, the first vertical end portion E11 is lifted upward by the user, and the first folding region R1 is opened in the vertical direction X with the first folding line L1 as the axis, whereby the entire package 10 is opened. This is the embodiment shown in 1.

In the package 10, the positional relationship between the tab tape T and the first squeezing area 2 and the second squeezing area 4 is defined as follows, so that the user can more easily pick the tab tape T at the time of opening, which is convenient at the time of opening. The sex can be improved.

[Positional relationship between the first and second squeezed areas and the tab tape]
As shown in FIGS. 3 and 4, at least one of the first squeezed region 2 and the second squeezed region 4 is the opening auxiliary squeezed region P, and the fixed portion T1 is viewed from the thickness direction Z of the package 10. It overlaps with or is located near.
In the examples shown in FIGS. 3 and 4, the first squeezing region 2 is located in the vicinity of the fixing portion T1 in the plan view from the thickness direction Z of the package 10 as the opening auxiliary squeezing region P. The opening auxiliary pressing region P may be both the first pressing region 2 and the second pressing region 4.

"The opening auxiliary pressing region P overlaps with the fixed portion T1 in the plan view from the thickness direction Z of the package 10" means that the opening auxiliary pressing region P and the fixed portion T1 overlap at least a part in the plan view. To say that you are.
Further, "the opening auxiliary pressing area P is located in the vicinity of the fixed portion T1 in the plan view" means that the distance between the fixed portion T1 and the opening auxiliary pressing area P in the plan view is 25 mm. It means to be located within. As a result, when the user presses the fixed portion T1 with the thumb, the thumb can be arranged at a position overlapping the opening auxiliary pressing region P in the plan view, so that the effect described below can be exhibited. ..
In the embodiment in which the opening auxiliary pressing region P overlaps with or is located in the vicinity of the fixed portion T1 in the plan view, the opening auxiliary pressing region P overlaps with the absorber 11 sandwiched in the thickness direction Z. Is not included.

Since the first squeezed region 2 and the second squeezed region 4 have a compressed and recessed structure, a step is formed at the boundary portion with the surroundings. In the above configuration, when the protruding portion T2 is picked up, the user presses the vicinity of the fixed portion T1 with a finger or the like, and the pressed exterior material 16 sinks downward due to the step formed by the opening auxiliary pressing region P. Include. As a result, the protruding portion T2 of the tab tape T floats upward, the user can easily pick the protruding portion T2, and the package 10 can be easily opened. Further, since the opening auxiliary squeezing region P has a higher rigidity than the surroundings, the user can easily push in the vicinity thereof due to the difference in feel from the surroundings, and the protrusion T2 is promoted to float.
Therefore, with the above configuration, the protruding portion T2 of the tab tape T can be easily grasped, and the package 10 of the napkin 1 can be easily opened.

The above-mentioned action and effect will be described more specifically. Since the package 10 folds the absorber 11 having some elasticity, a force in the direction of opening upward in the thickness direction Z always acts on the second folding region R2 and the first folding region R1. That is, in the package 10, each folded region is sealed by the side sealing portion F and the tab tape T against this force to maintain the tri-fold shape. For this reason, the package 10 does not have a dense laminated structure, but leaves a gap inside due to a step in each configuration. As a result, in the inside of the package 10, a gap in the thickness direction Z due to the step is formed in the upper and lower sides of the first squeezing region 2 and the lower region of the second squeezing region 4. This gap contributes to the sinking when the vicinity of the fixed portion T1 is pressed, and the protruding portion T2 of the tab tape T is easily lifted upward.

[Arrangement of opening auxiliary pressing area and tab tape]
As shown in FIG. 3, both the opening auxiliary pressing region P and the tab tape T are located at the central portion C in the lateral direction Y of the package 10.
The “central portion C in the lateral direction Y of the package 10” is the central region when the package 10 is divided into three equal parts in the lateral direction Y.

With this configuration, even when the tab tape T is picked and opened from an oblique direction with respect to the vertical direction X or from the horizontal direction Y, the influence of the tension acting on the exterior material 16 by the picked tab tape T affects the exterior. It becomes easy to extend to both sides of the material 16 in the lateral direction Y. As a result, the second folding region R2 can be easily peeled off from the first folding region R1, and the package 10 can be opened more easily.

The above-mentioned action and effect will be described more specifically. By arranging the tab tape T and the opening auxiliary pressing area P in the central portion C, when the tab tape T is grasped and lifted upward, the left and right side portions are sealed from the fixing portion T1 of the tab tape T via the exterior material 16. Tension is more likely to act on the portion F more evenly. Therefore, even when the tab tape T is gripped from a direction other than the vertical direction X, such as an oblique direction with respect to the vertical direction X or the horizontal direction Y as described above, the left and right side sealing portions F are opened. It becomes easier to open, and the convenience of opening can be improved.

[Detailed configuration of opening auxiliary squeezing area]
As shown in FIGS. 1 to 3, the opening auxiliary squeezing region P, which is at least one of the first squeezing region 2 and the second squeezing region 4, extends in the vertical direction X, and a plurality of linear linear regions arranged apart from each other. Includes squeeze groove 3. In the package 10, both the first squeezing region 2 and the second squeezing region 4 include a plurality of squeezing grooves 3 having the above configuration.

The squeezing groove 3 is a highly rigid portion in which the absorbent core 6 and the core wrap sheet 7 of the absorber 11 are compressed and compacted in the thickness direction Z. On the other hand, the region between the adjacent squeezing grooves 3 is somewhat compacted due to the influence of the squeezing grooves 3, but the rigidity is smaller than that of the squeezing grooves 3. Therefore, when the fixing portion T1 is pressed, the region between the pressing grooves 3 of the opening auxiliary pressing region P is easily compressed in the thickness direction Z, and the fixing portion T1 is easily pushed downward. Therefore, the protruding portion T2 of the tab tape T tends to float upward, and the package 10 can be opened more easily.

[Positional relationship between tab tape and first squeezed area]
As shown in FIG. 3, the protruding portion T2 of the tab tape T includes an adhesive region T3 and a non-adhesive region T4. The first squeezed region 2 is configured so as not to overlap the non-adhesive region T4 in a plan view of the package 10 when viewed from the thickness direction Z. That is, the first squeezed region 2 is not located below the non-adhesive region T4.

As a result, the non-adhesive region T4 is configured not to sink downward due to the step caused by the first squeezed region 2. Therefore, the non-adhesive region T4 is arranged on a substantially flat surface, and when the fixed portion T1 is pressed, the non-adhesive region T4 is easily lifted, and the package 10 is more easily opened.

[Positional relationship between the vertical peripheral edge of the folded area and the pressed area]
As shown in FIGS. 1, 3 and 4, the first folding region R1 includes the first longitudinal peripheral edge portion E1 in which the absorber 11 does not exist. Similarly, the second folding region R2 includes a second longitudinal peripheral edge E2 in which the absorber 11 is absent.

As shown in FIG. 1, the first longitudinal peripheral portion E1 is a region of the first folding region R1 located further behind the rear end portion 11b of the absorber 11. The first longitudinal peripheral edge E1 includes a region in which the napkin 1 is present and a region in which the napkin 1 is not present. The region where the napkin 1 exists is composed of, for example, a laminated body of the rear end portion of the napkin 1 composed of the front surface sheet 12 and the back surface sheet 13 and the exterior material 16. The area where the napkin 1 does not exist consists of only the exterior material 16.
Similarly, the second longitudinal peripheral portion E2 is also a region of the second folding region R2 that is located further in front of the front end portion 11a of the absorber 11. The second longitudinal peripheral edge E2 includes a region in which the napkin 1 is present and a region in which the napkin 1 is not present. The region where the napkin 1 exists is composed of, for example, a laminated body of the front end portion of the napkin 1 composed of the front surface sheet 12 and the back surface sheet 13 and the exterior material 16. The area where the napkin 1 does not exist consists of only the exterior material 16.
As described above, the first longitudinal peripheral edge E1 and the second longitudinal peripheral edge E2 are located in the first folding region R1 and the second folding region R2 from the regions where the first squeezing region 2 and the second squeezing region 4 exist. Is an even thinner area.

As shown in FIGS. 3 and 4, when the package 10 is folded, the first longitudinal peripheral edge portion E1 extends toward the second folded end portion RE2. The end portion of the first vertical peripheral portion E1 is the above-mentioned first vertical end portion E11, and is located in the vicinity of the second folded end portion RE2.
On the other hand, the second longitudinal peripheral edge portion E2 extends toward the first folded end portion RE1. The end of the second vertical peripheral edge E2 is the above-mentioned second vertical end E21 on which the tab tape T is arranged.

As shown in FIGS. 3 and 4, the second squeezed region 4 is an end portion (first) of the first longitudinal peripheral portion E1 than the first squeezed region 2 in a plan view seen from the thickness direction Z of the package 10. Vertical end) Located on the E11 side.
Between the first squeezed region 2 and the second squeezed region 4, at least a part of the first longitudinal peripheral edge E1 and the second longitudinal peripheral edge E2 is located in a plan view of the package 10 when viewed from the thickness direction Z. Located on top of each other. That is, among the first fold region R1 and the second fold region R2, the first squeeze region 2 and the second squeeze region 4 exist between the first squeeze region 2 and the second squeeze region 4 in the plan view. A portion thinner than the region is arranged.

As described above, the package 10 does not have a dense laminated structure, but leaves a gap inside due to the step of each configuration. Therefore, there are gaps in the upper and lower sides of the first longitudinal peripheral edge E1 inside the package 10 and the lower regions of the second longitudinal peripheral edge E2 due to the thin thickness of these peripheral edges. Is formed. This gap is located between the first squeezing region 2 and the second squeezing region 4 in the plan view, that is, in the vicinity of the opening auxiliary squeezing region P. Therefore, a part of the finger pressing the fixed portion T1 is located above this gap, and the finger enters this gap due to the pressing and tends to sink further downward. Therefore, the protruding portion T2 of the tab tape T becomes easier to float, and the package 10 can be opened more easily.

(Detailed positional relationship between the tab tape and the pressed area)
With reference to FIG. 3, when the first squeezing region 2 is configured as the opening auxiliary squeezing region P, the distance k between the fixing portion T1 and the first squeezing region 2 in the vertical direction X is preferably 3 mm or less. As a result, the first squeezed region 2 is arranged near or overlaps with the fixed portion T1, and the protruding portion T2 can be satisfactorily raised when the fixed portion T1 is pressed by the action of the step of the first squeezed region 2. ..
The distance k between the fixed portion T1 and the first squeezed region 2 in the vertical direction X is the vertical direction X on the second folded end portion RE2 side of the fixed portion T1 in a plan view seen from the thickness direction Z of the package 10. It is the distance in the vertical direction X from the end portion to the portion of the first squeezed region 2 closest to the first folded end portion RE1.

(Other configuration examples of the package)
In FIGS. 1 to 4, an example in which the package 10 is folded in the vertical direction X by two folding lines and the first pressing region 2 functions as the opening auxiliary pressing region P has been described, but the present invention is not limited to this.

For example, the package may be folded in the vertical direction X by three folding lines extending in the horizontal direction Y. In this case, it is assumed that the first fold line, the third fold line, and the second fold line are arranged on the package from the side closer to the first squeeze area.
The area including the first squeezed area defined by the first fold line is referred to as the first fold area. The area including the second squeezed area, which is partitioned by the second fold line, is referred to as the second fold area. The area partitioned by the third fold line and the second fold line, which is located between the first fold area and the second fold area, is referred to as a third fold area. The area partitioned by the third fold line and the first fold line is referred to as the fourth fold area.
For example, the first fold area and the fourth fold area are areas of the napkin including a posterior area located on the dorsal side of the wearer's excretory part when worn. The second folded region is an region of the napkin that includes an anterior region located ventral to the wearer's excretory portion when worn. The third fold area is an area of the napkin including an area facing the excretion part of the wearer when worn.

To fold the package 10, first, the laminate of the napkin and the exterior material is folded with the first fold line as the fold axis and the first fold area on the fourth fold area. Next, the folded first fold area and the fourth fold area are further folded on the third fold area with the third fold line as the fold axis. Next, the second folding area is folded over the folded first, third, and fourth folding areas with the second folding line as the folding axis. Then, the tab tape fixed to the second folding region is detachably adhered to the exterior material of the fourth folding region.

In this package, an absorber of the fourth folding region exists between the first pressing region located in the first folding region and the tab tape. Therefore, the first squeezed region is not included in the above-mentioned "opening auxiliary squeezed region overlaps with or is located near the fixed portion in a plan view from the thickness direction of the package".
On the other hand, when the second squeezed region is located in the vicinity of the fixed portion in the plan view, the second squeezed region functions as an opening auxiliary squeezed region. Therefore, even in such a four-fold package, if the second squeezed region is located near the fixed portion in the plan view, the protruding portion floats upward when the fixed portion is pressed, and the package 10 is opened. Can be easily performed.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
In the above-described embodiment, an example is shown in which the planar shapes of the first squeezed region 2 and the second squeezed region 4 are substantially rectangular, but the shape is not limited to this, and at least one of them is a flat surface with the fixing portion T1 of the tab tape T. It suffices if they overlap or are located close to each other visually.
The first squeezing region 2 and the second squeezing region 4 are not limited to the configuration having the squeezing groove 3, and include, for example, a squeezed portion having an arbitrary planar shape such as a dot shape in a plan view seen from the thickness direction Z of the napkin 1. You may be.
The package 10 is not limited to the above-described configuration, and may include, for example, a release sheet between the exterior material 16 and the napkin 1.

In the above embodiments, examples of sanitary napkins are shown as absorbent articles, but the present invention is not limited thereto. The absorbent article of the present invention may be, for example, a urine absorbing pad, a vaginal discharge sheet, or the like.
