<< Basic configuration of pants-type disposable diapers >>
FIG. 1 is a schematic perspective view of a pants-type disposable diaper 1 (hereinafter referred to as “diaper”). FIG. 2A is a plan view of the diaper 1 in a state of being extended in the longitudinal direction of the absorbent body 10 and the belt portion 20, and FIG. 2B is a cross-sectional view taken along the line AA of FIG. 2A. FIG. 3A is a plan view of the diaper 1 in which the connecting portions 2 and 3 of FIG. 2A are separated and developed, and FIG. 3B is a cross-sectional view taken along the line AA of FIG. 3A.

The state in which the diaper 1 is extended is a state in which the diaper 1 is extended so that the wrinkles formed in the diaper 1 are substantially invisible. Specifically, it is in a state of being stretched until the dimensions of each member (for example, the sheet 41 shown in FIG. 3B) constituting the diaper 1 are equal to or close to the dimensions of the member alone.

The diaper 1 is in a pants-type state as shown in FIG. 1 when worn. The pants-shaped diaper 1 has a vertical direction, a horizontal direction, and a front-rear direction orthogonal to each other, and a waist circumference opening BH and a pair of leg circumference openings LH are formed. In the vertical direction, the waist opening BH side is the upper side, and the opposite side is the lower side. In the anterior-posterior direction, the ventral side of the wearer is the anterior side and the dorsal side of the wearer is the posterior side. Further, as shown in FIG. 2B, the direction in which the members constituting the diaper 1 are laminated is defined as the thickness direction. In the thickness direction, the side in contact with the wearer is the skin side, and the opposite side is the non-skin side.

The diaper 1 has an absorbent body 10, a pair of belt portions 20, and a pair of leg gather portions 30. The pair of leg gather portions 30 are arranged along both lateral portions of the absorbent body 10. Further, in the flat diaper 1 (FIG. 2A), the absorbent main body 10, the pair of belt portions 20, and the pair of leg gather portions 30 are aligned in the longitudinal directions, and the absorbent main body 10 and the pair of leg gathers 30 are aligned. A pair of belt portions 20 are superposed on the skin surface, and the skin side surfaces face each other. In the flat diaper 1, the inner ends 20a in the width direction of the pair of belt portions 20 are opened outward, the belt portions 20 are folded in half at substantially the center in the longitudinal direction, and the absorbent body 10 and the leg gather portions 30 are folded. By folding it in half at approximately the center in the longitudinal direction, it becomes a diaper 1 (FIG. 1) in a pants-shaped state.

In the pants-shaped diaper 1 (FIG. 1), the absorbent body 10 and the pair of leg gather portions 30 are folded in half so that the longitudinal direction thereof is along the vertical direction of the diaper 1. The pair of belt portions 20 are arranged along the lateral direction on both sides of the absorbent main body 10 in the lateral direction, respectively. Specifically, one end of each belt portion 20 is connected to the end portion of the absorbent body 10 and the leg gather portion 30 in the longitudinal direction at the connection portion 2 on the front side, and the other end of each belt portion 20 is on the rear side. In the connecting portion 3 of the above, the absorbent body 10 and the leg gather portion 30 are connected to the end portions in the longitudinal direction. That is, the diaper 1 is provided with a pair of connecting portions 2, 2, 3, and 3 on both sides in the front-rear direction, respectively.

Further, each of the connecting portions 2 and 3 is inclined laterally outward from the waist circumference opening BH side toward the leg circumference opening LH side. As the connection method at the connection portions 2 and 3, known connection methods such as heat seal, ultrasonic seal, adhesive, and a combination thereof can be exemplified.

Further, in the pants-type diaper 1, the belt portion 20 can be expanded and contracted in the horizontal direction, the leg gather portion 30 can be expanded and contracted in the vertical direction, and the diaper 1 fits around the waist and legs of the wearer. Therefore, in the belt portion 20, a large number of elastic members 21 along the lateral direction of the diaper 1 (longitudinal direction of the belt portion 20) are arranged side by side in the vertical direction. In the leg gather portion 30, a plurality of elastic members 31 along the vertical direction of the diaper 1 (longitudinal direction of the leg gather portion 30) are arranged side by side (here, two are arranged side by side). Examples of the elastic members 21 and 31 include thread-shaped elastic members such as rubber and spandex, but sheet-shaped elastic members such as stretchable non-woven fabrics and stretchable films may be used.

In the absorbent body 10, as shown in FIG. 2B, a liquid-permeable top sheet 11, an absorber 12, a liquid-impermeable back sheet 13, and an exterior sheet 14 are laminated from the skin side in the thickness direction. .. In the absorber 12, the absorbent core that absorbs the liquid is coated with a liquid-permeable core wrap sheet. As the absorbent core, a liquid absorbent fiber such as pulp fiber containing a highly absorbent polymer can be exemplified.

As shown in FIG. 3B, the leg gather portion 20 and the belt portion 30 are formed of the same seat member 40. In the seat member 40, the elastic member 21 of the belt portion 20 and the elastic member 31 of the leg gather portion 30 are fixed between the two sheets 41 in an extended state. Further, the seat member 40 has a hole for the leg opening LH.

In the diaper 1 production line, as shown in FIG. 3B, a pair of sheet members 40 are arranged on both sides of the absorbent body 10 in the lateral direction. Then, at the folding position F0 along the longitudinal direction of the seat member 40 and passing through the hole for the leg circumference opening LH, the seat member 40 is folded back toward the skin side surface side of the absorbent body 10, and the state shown in FIG. 2B is obtained. Become. Of the seat member 40, the portion overlapping the absorbent main body 10 in the thickness direction is the belt portion 20, and the portion aligned laterally with the absorbent main body 10 is the leg gather portion 30. Then, by forming the pair of connecting portions 2 and 2 on the front side and the pair of connecting portions 3 and 3 on the rear side, the folded state of the seat member 40 is fixed, and the flat diaper 1 (FIG. 2A) is formed. Will be done. However, the present invention is not limited to this, and the belt portion 20 and the leg gather portion 30 may be formed of separate members.

<< Pants-type absorbent article packaging >>
FIG. 4A is a plan view of the front side of the package 50 of the above-mentioned diaper 1 (pants-type absorbent article), and FIG. 4B is a plan view of the back side of the package 50.
The package 50 has a first direction, a second direction, and a thickness direction orthogonal to each other, and includes the diaper 1 and the diaper 1 at folding positions F3 and F4 along the first direction (predetermined direction). The folded wrapping sheet 51, the fastening tape 52 that fastens the opening end 51a located on the outer side of the ends 51a and 51b along the first direction of the wrapping sheet 51 to the outer surface of the wrapping sheet 51, and the first It has a pair of sealing portions 53 that seal both end portions of the packaging sheet 51 in one direction. As the packaging sheet 51, a flexible sheet such as SMS non-woven fabric can be exemplified. The fastening tape 52 has a rectangular shape and is arranged at the center of the package 50 in the first direction.

5A to 5C are explanatory views of a folding method of the diaper 1. FIG. 6 is an explanatory diagram of a folding method of the packaging sheet 51. FIG. 7A is a schematic perspective view of the diaper 1 showing the folded state of the belt portion 20, FIG. 7B is a schematic cross-sectional view of the package 50 cut in the first direction, and FIG. 7C is a modification of the folding method of the belt portion 20. It is a figure explaining an example.
It is assumed that the packaging body 50 includes the folded diaper 1 and the packaging sheet 51 is folded. That is, the folding of the diaper 1 and the folding of the packaging sheet 51 are independent.

Therefore, in the production line of the package 50, the diaper 1 is first folded. At the folding position F1 shown in the pants-shaped diaper 1 of FIG. 5A, the lateral end 20A of the belt portion 20 is folded inward in the lateral direction, and the diaper 1 is in the state of FIG. 5B. The folding position F1 is located on the belt portion 20 on the outer side in the lateral direction from the connecting portion 2, and is inclined with respect to the vertical direction like the connecting portion 2. Further, as shown in FIGS. 5B and 7A, the lateral end portion 20A of the belt portion 20 is folded inward in the lateral direction so that its non-skin side surfaces face each other, and is folded in half in the longitudinal direction. It is arranged so as to be sandwiched between the absorbent main bodies 10.

After that, the absorbent main body 10 is folded in half in the vertical direction at the folding position F2 along the horizontal direction at substantially the center of the diaper 1 in the vertical direction, and the diaper 1 is in the state shown in FIG. 5C. The diaper 1 folded in the state shown in FIG. 5C is included in the packaging sheet 51. That is, in the package 50 of the present embodiment, the diaper 1 (absorbent body 10) is folded in half in the vertical direction. However, the number of folds is not limited to one. Further, in FIG. 5C, the diaper 1 is folded in half with the ventral side inside. That is, the diaper 1 is folded in half so that the connecting portion 2 on the front side is covered with the lower end portion 10B of the absorbent body 10, but the diaper 1 may be folded in half with the back side portion inside.

As shown in FIG. 6, the folded diapers 1 are transported in a line at predetermined intervals with the direction corresponding to the first direction of the package 50 as the transport direction. Hereinafter, the transport direction is referred to as the MD direction, and the direction orthogonal to the MD direction (the direction corresponding to the second direction of the package 50) is referred to as the CD direction. Then, the continuous body 51'of the packaging sheets continuous in the MD direction joins the diapers 1 that are transported side by side in the MD direction. Specifically, the continuous body 51'of the packaging sheet joins from below with the upper portion 10A (the side where the connecting portion 3 on the rear side is located) of the absorbent body 10 folded in half as the upper surface, and the diaper 1 is the packaging sheet. It is transported in a state of being placed on the continuum 51'.

Next, at the folding position F3 along the MD direction on the front side in the CD direction from the diaper 1, the end portion 51'B on the front side in the CD direction of the continuous body 51'of the packaging sheet is folded inward in the CD direction. Similarly, at the folding position F4 along the MD direction on the back side in the CD direction from the diaper 1, the end portion 51'A on the back side in the CD direction of the continuous body 51'of the packaging sheet is folded inward in the CD direction. That is, in the packaging body 50 of the present embodiment, the packaging sheet 51 is folded in three at the folding positions F3 and F4 along the first direction. However, the number of folds is not limited to two. Further, a part of the continuous body 51'of the packaging sheet folded inward in the CD direction overlaps, and as shown in FIG. 4A, the overlapping portion 51C of the packaging sheet 51 is formed in the packaging body 50. Further, the end 51'a of the continuous body 51'of the packaging sheet that is folded later corresponds to the opening end 51a of the packaging body 50.

Next, the fastening tape 52 is adhered to the outer surface of the continuous body 51'of the packaging sheet so as to straddle the opening end 51a. Examples of the fastening tape 52 include those in which an adhesive is applied to one side of a film such as polyethylene or polypropylene.

Next, a pair of sealing portions 53 are formed between the diapers 1 arranged in the MD direction. Of the pair of sealing portions 53, the downstream sealing portion 53a serves as the sealing portion of the downstream packaging body 50, and the upstream sealing portion 53b serves as the sealing portion of the upstream packaging body 50. As the sealing method in the sealing portion 53, known connection methods such as heat sealing, ultrasonic sealing, adhesives, and combinations thereof can be exemplified. Finally, the space between the pair of sealing portions 53a and 53b is cut along the CD direction to complete the package 50. In the market, a large number of packages 50 are distributed.

As described above, in the packaging body 50 of the present embodiment, the wrapping sheet 51 is folded by including the folded diaper 1, and the diaper 1 is not folded together with the wrapping sheet 51. Therefore, even if the user unfolds the packaging sheet 51, the folded state of the diaper 1 is maintained, and the hygienic state of the diaper 1 is maintained until the end.

Further, the folded state of the packaging sheet 51 is maintained only by providing the packaging body 50 with a pair of sealing portions 53. However, by providing the fastening tape 52 at the opening end 51a of the packaging sheet 51 as in the packaging 50 of the present embodiment, the user can immediately recognize the opening position of the packaging 50. Further, since the user can peel off the sealing portion 53 while pinching the fastening tape 52 to unfold the packaging sheet 51, the packaging sheet 51 can be easily opened. In this way, the package 50 can be easily opened.

Further, the color of the adhesive tape 52 (for example, blue) may be different from the color of the packaging sheet 51 or the color of the sheet constituting the diaper 1 (for example, white). By doing so, the fastening tape 52 becomes conspicuous, and the opening position of the package 50 becomes more easily recognized. Further, it is preferable that the end portion 52A of the fastening tape 52 on the side opposite to the side where the packaging sheet 51 is opened first (lower side in the second direction in FIG. 4A) is not fastened to the packaging sheet 51. By doing so, the user can easily pick up the fastening tape 52, and the package 50 can be opened more easily.

FIG. 8A is a diagram for explaining the movement allowance L3 of the diaper 1 of the packaging body 50, and FIG. 8B is a plan view of the packaging body 50 in which a part of the packaging sheet 51 is folded. FIG. 9A is a diagram for explaining the movement allowance L3 of the package 50 of the modified example, and FIG. 9B is a plan view of the package 50 of the modified example in which a part of the packaging sheet 51 is folded.

As shown in FIG. 8A, the packaging body 50 of the present embodiment is a diaper that is folded from the inner dimension L1 of the packaging sheet 51 (that is, the length L1 between the pair of sealing portions 53) in the first direction. It has a "movement allowance L3 (= L1-L2)" which is the length obtained by subtracting the length L2 of 1. Then, the length L5 (first length of the present invention = L3 + L4) obtained by adding the length L4 of the sealing portion 53 in the first direction to the moving allowance L3 is the length L5 of the package 50 on one side in the first direction. It is longer than the half length L6 / 2 (second length of the present invention) of the length L6 from the side end 50a to the side end 52a of the fastening tape 52 (L5> L6 / 2).

That is, in the package 50, the moving allowance L3 of the diaper 1 is large, and the diaper 1 is loosely packaged. Therefore, it is difficult for diaper 1 to have a habit of folding. Therefore, the diaper 1 (particularly the absorbent main body 10) is in close contact with the wearer and can prevent leakage of excrement and deterioration of wearing comfort.

Further, the diaper 1 is moved to one side in the first direction (the other side in FIG. 8A) in the packaging sheet 51, and the portion of the packaging sheet 51 where the diaper 1 is not located is folded. Specifically, the packaging sheet 51 is folded with the end 1a of the diaper 1 on the side opposite to the side where the diaper 1 is brought in the first direction (one side in FIG. 8A) as the folding position. Then, as shown in FIG. 8B, at least a part of the fastening tape 52 can be covered with the wrapping sheet 51. Therefore, it is possible to prevent unnecessary peeling of the adhesive tape 52. For example, by setting the packaging body 50 to the state shown in FIG. 8B when the packaging body 50 is carried, it is possible to prevent the packaging sheet 51 from unfolding and exposing the diaper 1, and the hygienic state of the diaper 1 is maintained until the end.

Further, it is difficult to visually recognize the contents (diaper 1) from the outside at the portion 50A (FIG. 8B) of the packaging body 50 on which the packaging sheets 51 are folded. Therefore, when the movement allowance L3 is large as in the packaging body 50 of the present embodiment, the portion 50A of the packaging body 50 in which the packaging sheet 51 is folded is also large, and the diaper 1 can be removed from the outside of the packaging body 50 by setting the state shown in FIG. 8B. It becomes difficult to see. Therefore, even a user who is reluctant to use the diaper 1 can easily carry the package 50.

Further, as shown in FIG. 9A, in the first direction, the length L5 (= L3 + L4) obtained by adding the length L4 of the sealing portion 53 to the movement allowance L3 (= L1-L2) is one side in the first direction. It is more preferable that the length from the side end 50a of the packaging body 50 to the side end 52b of the fastening tape 52 on the other side is half the length L8 of L8 (the third length of the present invention) or more. (L5 ≧ L8 / 2).

By doing so, the moving allowance L3 of the diaper 1 becomes larger, and the diaper 1 is loosely wrapped, so that the diaper 1 is less likely to have a habit of folding.
Further, as shown in FIG. 9B, the diaper 1 is moved to one side in the first direction in the packaging sheet 51, and the portion of the packaging sheet 51 where the diaper 1 is not located is folded with the end 1a of the diaper 1 as the folding position. Then, the entire fastening tape 52 can be covered with the wrapping sheet 51. Therefore, unnecessary peeling of the adhesive tape 52 can be prevented more reliably. Further, in the state of FIG. 9B, the portion 50A of the packaging body 50 on which the packaging sheet 51 is folded becomes large, and the diaper 1 is more difficult to be visually recognized from the outside of the packaging body 50.

Further, the length L4 of the sealing portion 53 in the first direction is shorter than the movement allowance L3 (L4 <L3) so that the movement allowance L3 becomes larger than the length L7 of the fastening tape 52 in the first direction. It is also preferable that it is short (L4 <L7).

Further, it is preferable that the portion 51a1 (see FIG. 4A) between the fastening tape 52 and the sealing portion 53 of the package 50 opening end 51a is not fastened to the outer surface of the packaging sheet 51. That is, it is preferable that the overlapping portion 51C of the packaging sheet 51 is not adhered to each other at the portion between the fastening tape 52 and the sealing portion 53, and the outside and the inside of the packaging sheet 51 communicate with each other.

By doing so, the portion 51a1 between the fastening tape 52 and the sealing portion 53 becomes an air passage, and the inside of the packaging sheet 51 is not sealed. Therefore, the diaper 1 is loosely wrapped, and the diaper 1 is less likely to have a habit of folding. Further, by not sealing the inside of the wrapping sheet 51, the wrapping sheet 51 can be prevented from bursting and the diaper 1 can be prevented from being unnecessarily exposed.

Further, in this case, it is preferable that the diaper 1 is not folded together with the packaging sheet 51 as in the packaging body 50 of the present embodiment. By doing so, even if a foreign substance such as a finger enters between the fastening tape 52 and the sealing portion 53 (51a1), it is difficult for the foreign substance to come into contact with the diaper 1, and the hygienic state of the diaper 1 is maintained. Further, by providing the fastening tape 52 on the packaging body 50, a part of the opening end 51a can be stopped by the fastening tape 52 while creating an air passage between the pair of sealing portions 53, and foreign matter is mixed. It can be said that it becomes difficult to do. However, not limited to the above, the overlapping portion 51C of the packaging sheet 51 between the fastening tape 52 and the sealing portion 53 may be adhered.

The packaging sheet 51 is preferably a non-woven fabric having a basis weight of 10 to 25 g / m ^2. By setting the basis weight of the packaging sheet 51 to 10 g / m ² or more, the thickness of the sheet can be obtained so that the diaper 1 inside is not contaminated from the outside, and the hygienic state of the diaper 1 is maintained. On the other hand, by setting the basis weight of the packaging sheet 51 to 25 g / m ² or less, as shown in FIG. 8B, the air inside can be evacuated from the surface of the portion 50A where a part of the packaging sheet 51 is folded. Therefore, it is possible to prevent the fastening tape 52 from coming off and the packaging sheet 51 from opening due to air escaping only from the opening end 51a of the packaging sheet 51. For the same reason, when the packaging sheet 51 is made into a film, it is difficult for air to escape from the surface, and air tends to escape only from the opening end 51a. Therefore, it is preferable to make the packaging sheet 51 a non-woven fabric.

Further, as described above, in the packaging sheet 51, in the diaper 1, both ends 20A in the lateral direction of the belt portion 20 are folded inward in the lateral direction (FIG. 5B), and the diaper 1 is at the folding position F2 along the lateral direction. The absorbent body 10 is vertically folded (FIG. 5C).

Therefore, the diaper 1 in the package 50 can be made compact, and the package 50 of the present embodiment having a relatively large movement allowance L3 can be made compact. Further, the belt portion 20 can be expanded and contracted in the lateral direction, and when the belt portion 20 is visually recognized from the outside of the packaging body 50, it is easy to recognize that the content of the packaging body 50 is the diaper 1. Therefore, by folding the belt portion 20 inward in the lateral direction as described above, the size of the belt portion 20 that can be visually recognized from the outside of the packaging body 50 can be reduced, and it is difficult to be recognized as the diaper 1 from the outside of the packaging body 50. Become. Therefore, even a user who is reluctant to use the diaper 1 can easily carry the package 50.

In the package 50 of the present embodiment, as shown in FIGS. 5B and 7A, the non-skin side surfaces of the lateral end 20A of the belt portion 20 face each other and are located on the skin side of the absorbent body 10. (That is, sandwiched between the absorbent bodies 10), the lateral end 20A of the belt portion 20 is folded inward in the lateral direction. Therefore, the size of the belt portion 20 that can be visually recognized from the outside of the package 50 can be reduced, and it becomes difficult to recognize the diaper 1 from the outside of the package 50.

Further, as in the modified example of FIG. 7C, the lateral end portion 20A of the belt portion 20 may be folded inward in the lateral direction so as to be located on the non-skin side of the absorbent body 10. Also in this case, the absorbent body 10 is folded in half in the vertical direction at the folding position F2 so that the lateral end 20A of the belt portion 20 is on the inside, so that the belt can be visually recognized from the outside of the package 50. The size of the portion 20 can be reduced.

However, by folding the belt portion 20 like the package 50 of the present embodiment (FIGS. 5B and 7A), the lateral end portion 20A of the belt portion 20 is sandwiched between the absorbent main bodies 10 and the belt is formed. The folded state of the portion 20 is easily maintained.
Further, as shown in FIG. 7A, the ventral upper end 10a and the dorsal upper end 10b of the absorbent main body 10 are separated in the front-rear direction by the amount that the belt portion 20 is sandwiched between them. Therefore, when the diaper 1 is worn, the user can easily pick up the upper ends 10a and 10b of the absorbent body 10, and the waist opening BH can be easily widened.
Further, since a part of each belt portion 20 overlaps, the length of the belt portion 20 folded inward in the lateral direction (L9 in FIG. 7A) is shorter than that in FIG. 7C. Therefore, the belt portion 20 is unlikely to intersect the double-folded position F2 of the absorbent main body 10, and the double-folded state of the absorbent main body 10 is easily maintained.

Further, in the diaper 1 (FIG. 1) of the present embodiment, the connecting portions 2 and 3 connecting the end portion of the absorbent main body 10 and the belt portion 20 are directed from the waist circumference opening BH side toward the leg circumference opening side LH. It is inclined outward in the lateral direction. Therefore, as shown in FIGS. 1 and 5A, the diaper 1 has a shape similar to that of underwear such as shorts and briefs, and is easy to use even for users who are reluctant to use the diaper 1.

Further, in the thickness direction of the package 50 (that is, the direction orthogonal to the surface of the fastening tape 52), the surface on the side where the fastening tape 52 is arranged is the front surface (FIG. 4A), and the opposite side is the back surface (the back surface (FIG. 4A)). FIG. 4B). On the surface of the package 50, the fastening tape 52 and the overlapping portion 51C of the packaging sheet 51 are arranged. Therefore, the diaper 1 in the package 50 is less visible on the front side than on the back side. Therefore, it is preferable that the upper end portion 10A of the absorbent main body 10 folded in half on the waist circumference opening BH side is located on the front surface side of the package 50, and the lower end portion 10B is located on the back surface side of the package 50.

By doing so, the belt portion 20 connected to the upper end portion 10A of the absorbent body 10 and the diagonally inclined connecting portion 3, that is, the portion easily recognized as the diaper 1 are located on the surface side. Therefore, it becomes difficult to see from the outside of the package 50. Therefore, the contents of the package 50 are less likely to be recognized as the diaper 1, and even a user who is reluctant to use the diaper 1 can easily carry the package 50.

Further, by arranging the upper end portion 10A of the absorbent main body 10 on the surface side, when the packaging body 50 is in the state of FIG. 8B, the portion 50A where the packaging sheet 51 folds prevents the adhesive tape 52 from peeling off. , The belt portion 20 and the connecting portion 3 are less likely to be visually recognized from the outside of the package 50. However, not limited to the above, the upper end portion 10A of the absorbent body 10 may be located on the back surface side of the package 50.

The shape of the diaper 1 included in the package 50 is not limited to the above. For example, one end of the absorbent body is connected to the center of the ventral belt along the lateral direction, the other end of the absorbent body is connected to the center of the dorsal belt along the lateral direction, and the ventral belt. It may be a diaper in which both lateral portions of the portion and the dorsal belt portion are connected. Also in this case, by folding the diaper 1 as described above and arranging the portion of the absorbent body on the waist circumference opening side on the surface side, the contents of the package 50 are less likely to be recognized as the diaper 1.

Further, in FIG. 5A, the folding position F1 of the belt portion 20 is inclined outward in the lateral direction from the waist circumference opening BH side toward the leg circumference opening LH side, but the present invention is not limited to this, and the folding position F1 of the belt portion 20 is not limited to this. May be along the vertical direction. However, when the folding position F1 is inclined, the size of the belt portion 20 visually recognized from the outside of the package 50 can be made smaller, and the contents of the package 50 are less likely to be recognized as the diaper 1.

Further, as shown in FIG. 4A, the lateral direction of the diaper 1 in the packaging sheet 51 is along the direction intersecting the first direction of the package 50 (here, the second direction orthogonal to the first direction). Therefore, the folding position F2 along the lateral direction for folding the absorbent main body 10 in two is orthogonal to the folding positions F3 and F4 along the first direction of the packaging sheet 51.

Therefore, the wrapping sheet 51 is less likely to receive the unfolding force of the diaper 1 that is folded inside, and the folded state of the wrapping sheet 51 is easily maintained. In other words, since the absorbent body 10 is difficult to deploy in conjunction with the deployment of the packaging sheet 51, the folded state of the diaper 1 is easily maintained even when the packaging sheet 51 is deployed, and the hygienic state of the diaper 1 is maintained until the end. Dripping.
Further, in the packaging body 50 of the present embodiment, since the portion 51a1 between the fastening tape 52 and the sealing portion 53 is not fastened, the folded state of the packaging sheet 51 can be easily maintained as described above. preferable.

Further, in the case of FIG. 4A, the waist opening BH of the diaper 1 faces the sealing portion 53 and does not face the folding positions F3 and F4 of the packaging sheet 51. Therefore, when the user unfolds the packaging sheet 51, it is difficult for a finger to enter the waist circumference opening BH. Therefore, the hygienic condition of the diaper 1 is maintained without touching the skin side surface of the diaper 1 to the end. However, not limited to the above, the lateral direction of the diaper 1 may be along the first direction of the package 50.

Although the embodiments of the present invention have been described above, the above-described embodiments are for facilitating the understanding of the present invention, and are not for limiting the interpretation of the present invention. Further, the present invention can be changed or improved without departing from the spirit thereof, and it goes without saying that the present invention includes an equivalent thereof.
