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

  In addition, the state which extended the diaper 1 is the state which extended the diaper 1 so that the wrinkle which had arisen in the diaper 1 would no longer be visually recognized. Specifically, it is a state in which each member constituting the diaper 1 (for example, the sheet 41 shown in FIG. 3B) is extended until the dimension thereof matches or is close to the dimension of the member itself.

  The diaper 1 is in a pants-type state as shown in FIG. 1 when worn. The pants-type diaper 1 has a vertical direction, a horizontal direction, and a front-rear direction orthogonal to each other, and a waistline opening BH and a pair of leg-hole 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 front-rear direction, the wearer's ventral side is the front side, and the wearer's back side is the rear side. Moreover, as shown to FIG. 2B, let the direction where each member which comprises the diaper 1 was laminated | stacked be a 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 includes an absorbent main body 10, a pair of belt parts 20, and a pair of leg gather parts 30. The pair of leg gathers 30 is disposed along both lateral sides of the absorbent main body 10. Moreover, in the diaper 1 (FIG. 2A) in a planar state, the longitudinal directions of the absorbent main body 10, the pair of belt portions 20, and the pair of leg gathers 30 are aligned, and the absorbent main body 10 and the pair of leg gathers 30 are aligned. A pair of belt portions 20 are superimposed on the skin surface, and the skin side surfaces of each other face each other. In the diaper 1 in a flat state, the absorbent main body 10 and the leg gathers 30 are opened while the inner ends 20a in the width direction of the pair of belt portions 20 are opened to the outside and the belt portion 20 is folded in half at the approximate center in the longitudinal direction. By folding in half at the approximate center in the longitudinal direction, the pants-type diaper 1 (FIG. 1) is obtained.

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

  Each of the connecting portions 2 and 3 is inclined outward in the lateral direction from the waistline opening BH side toward the leg periphery opening LH side. As a connection method in the connection parts 2 and 3, well-known connection methods, such as a heat seal, an ultrasonic seal, an adhesive agent, these combinations, can be illustrated.

  Moreover, in the diaper 1 of a pants-type state, the belt part 20 can be expanded / contracted in the horizontal direction, the leg gather part 30 can be expanded / contracted in the vertical direction, and the diaper 1 fits around the wearer's waist and legs. Therefore, many elastic members 21 along the horizontal direction of the diaper 1 (longitudinal direction of the belt part 20) are arranged in the belt part 20 along with the vertical direction. A plurality of elastic members 31 along the longitudinal direction of the diaper 1 (longitudinal direction of the leg gathering portion 30) are arranged in the leg gathering portion 30 in the lateral direction (two in this case). The elastic members 21 and 31 may be thread-like elastic members such as rubber and spandex, but may be sheet-like elastic members such as a stretchable nonwoven fabric and a stretchable film.

  In the absorbent main body 10, as shown in FIG. 2B, a liquid-permeable top sheet 11, an absorbent body 12, a liquid-impermeable back sheet 13, and an exterior sheet 14 are laminated from the skin side in the thickness direction. . In the absorbent body 12, a liquid permeable core wrap sheet is coated on an absorbent core that absorbs liquid. As an absorptive core, what contained superabsorbent polymer in liquid absorptive fibers, such as a pulp fiber, can be illustrated.

  The leg gather part 20 and the belt part 30 are formed of the same sheet member 40 as shown in FIG. 3B. In the sheet member 40, the elastic member 21 of the belt portion 20 and the elastic member 31 of the leg gather portion 30 are fixed in an extended state between the two sheets 41. Further, a hole for the leg opening LH is cut out in the sheet member 40.

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

<< Packing body of pants-type absorbent article >>
4A is a plan view of the front side of the package 50 of the diaper 1 (pants-type absorbent article) described above, 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 folding positions F3 and F4 including the diaper 1 along the first direction (predetermined direction). A wrapping sheet 51 folded, a fastening tape 52 that fastens the open end 51a located outside of the ends 51a, 51b along the first direction of the packaging sheet 51 to the outer surface of the packaging sheet 51; It has a pair of sealing part 53 which has sealed the both ends of the packaging sheet 51 in one direction. Examples of the packaging sheet 51 include a flexible sheet such as an SMS nonwoven fabric. 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 diagrams of a method for folding the diaper 1. FIG. 6 is an explanatory diagram of a method for folding the packaging sheet 51. 7A is a schematic perspective view of the diaper 1 showing the folded state of the belt portion 20, FIG. 7B is a schematic 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.
In the package 50, the folded diaper 1 is included 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 diaper 1 in the pant-type state 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 F <b> 1 is located on the outer belt portion 20 in the lateral direction than the connection portion 2, and is inclined with respect to the vertical direction in the same manner as the connection portion 2. Further, as shown in FIG. 5B and FIG. 7A, the end 20A in the lateral direction of the belt portion 20 is folded inward in the lateral direction so that the non-skin side faces each other, and folded in half in the longitudinal direction. It arrange | positions so that it may be pinched | interposed into the absorptive main body 10. FIG.

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

  As shown in FIG. 6, the folded diapers 1 are conveyed in a line at predetermined intervals with the direction corresponding to the first direction of the package 50 as the conveyance direction. Hereinafter, the conveyance 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. And the continuous body 51 'of the packaging sheet continuous in MD direction merges with the diaper 1 conveyed along with MD direction. Specifically, the upper part 10A of the absorbent main body 10 folded in half (the side on which the rear connection part 3 is located) is used as the upper surface, and the continuous body 51 'of the packaging sheet joins from below, and the diaper 1 is formed of the packaging sheet. It is transported while being placed on the continuum 51 ′.

  Next, the end portion 51'B on the near side in the CD direction of the continuous body 51 'of the packaging sheet is folded inward in the CD direction at a folding position F3 along the MD direction that is closer to the CD direction than the diaper 1. Similarly, at the folding position F4 along the MD direction on the back side in the CD direction with respect to 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 package 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 folding is not limited to two. Moreover, a part of the continuous body 51 ′ of the packaging sheet folded inward in the CD direction is overlapped, and an overlapping portion 51 </ b> C of the packaging sheet 51 is formed in the packaging body 50 as shown in FIG. 4A. Further, the end 51 ′ a of the continuous body 51 ′ of the packaging sheet that is folded later corresponds to the opening end 51 a of the packaging body 50.

  Next, the fastening tape 52 is bonded to the outer surface of the continuous body 51 ′ of the packaging sheet so as to straddle the open end 51 a. An example of the fastening tape 52 is one in which an adhesive is applied to one side of a film such as polyethylene or polypropylene.

  Next, a pair of sealing parts 53 are formed between the diapers 1 arranged in the MD direction. Of the pair of sealing portions 53, the downstream sealing portion 53 a becomes the sealing portion of the downstream packaging body 50, and the upstream sealing portion 53 b becomes the sealing portion of the upstream packaging body 50. In addition, as a sealing method in the sealing part 53, well-known connection methods, such as a heat seal, an ultrasonic seal, an adhesive agent, these combinations, can be illustrated. Finally, the space between the pair of sealing portions 53a and 53b is cut along the CD direction, and the package 50 is completed. In the market, many packages 50 are packaged.

  As described above, in the package 50 according to the present embodiment, the folded diaper 1 is included, the packaging sheet 51 is folded, and the diaper 1 is not folded together with the packaging sheet 51. Therefore, even if the user unfolds the packaging sheet 51, the folded state of the diaper 1 is maintained, and the sanitary state of the diaper 1 is maintained until the end.

  Moreover, the folding state of the packaging sheet 51 is maintained only by providing a pair of sealing portions 53 on the packaging body 50. However, the user can recognize the opening position of the packaging body 50 immediately by providing the fastening tape 52 at the opening end 51a of the packaging sheet 51 like the packaging body 50 of this embodiment. Moreover, since the user can peel off the sealing part 53 and unfold the packaging sheet 51 while grasping the fastening tape 52, the user can easily open it. In this way, the package 50 can be easily opened.

  Furthermore, the color (for example, blue) of the fastening tape 52 may be different from the color of the packaging sheet 51 and the color of the sheet (for example, white) constituting the diaper 1. By doing so, the fastening tape 52 is conspicuous and the opening position of the package 50 is more easily recognized. Further, it is preferable that the end portion 52 </ b> A of the fastening tape 52 on the side opposite to the side on which the packaging sheet 51 is first opened (the 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 package 50, and FIG. 8B is a plan view of the package 50 in which a part of the package sheet 51 is folded. FIG. 9A is a diagram for explaining the movement allowance L3 of the package 50 according to the modified example, and FIG. 9B is a plan view of the package 50 according to the modified example in which a part of the package sheet 51 is folded.

  As shown in FIG. 8A, the packaging body 50 of the present embodiment is a diaper folded in the first direction from the inner dimension L1 of the packaging sheet 51 (that is, the length L1 between the pair of sealing portions 53). 1 has a “movement allowance L3 (= L1−L2)” that is a length obtained by subtracting the length L2 of 1. And the length L5 (1st length of this invention = L3 + L4) which added the length L4 of the 1st direction of the sealing part 53 to the movement allowance L3 of the packaging body 50 of the one side in a 1st direction. It is longer than the length L6 / 2 (second length of the present invention) which is half 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 movement allowance L3 of the diaper 1 is large, and the diaper 1 is loosely packaged. For this reason, it is difficult for the diaper 1 to be folded. Therefore, the diaper 1 (especially the absorptive main body 10) closely_contact | adheres to a wearer, and can prevent the leakage of excrement and the fall of wearing comfort.

  Moreover, the diaper 1 is brought to the one side (the other side in FIG. 8A) of the 1st direction within the packaging sheet 51, and the site | part of the packaging sheet 51 in which 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 opposite side (one side in FIG. 8A) as the diaper 1 side in the first direction as the folding position. Then, as shown in FIG. 8B, at least a part of the fastening tape 52 can be covered with the packaging sheet 51. Therefore, unnecessary peeling of the fastening tape 52 can be prevented. For example, when the package 50 is carried, the state shown in FIG. 8B can be used to prevent the diaper 1 from being exposed when the packaging sheet 51 is unfolded, and the sanitary state of the diaper 1 is maintained until the end.

  In addition, at the portion 50A (FIG. 8B) of the package 50 where the packaging sheet 51 is folded, the contents (diaper 1) are hardly visible from the outside. Therefore, when the movement allowance L3 is large as in the package 50 of the present embodiment, the portion 50A of the package 50 where the packaging sheet 51 is folded is large, and the diaper 1 can be removed from the outside of the package 50 by making the state shown in FIG. 8B. It becomes difficult to see. Therefore, even a user who has a feeling of resistance to using the diaper 1 can easily carry the package 50.

  9A, in the first direction, a 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 it is not less than the length L8 / 2 (the third length of the present invention) which is half the length L8 from the side end 50a of the package 50 to the side end 52b of the other fastening tape 52. (L5 ≧ L8 / 2).

By doing so, since the movement allowance L3 of the diaper 1 becomes larger and the diaper 1 is loosely packaged, the diaper 1 is less likely to be folded.
9B, the diaper 1 is brought to one side in the first direction in the packaging sheet 51, and the part 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. Thus, the entire fastening tape 52 can be covered with the packaging sheet 51. Therefore, unnecessary peeling of the fastening tape 52 can be prevented more reliably. 9B, the portion 50A of the packaging body 50 where the packaging sheet 51 is folded is also increased, and the diaper 1 is more difficult to be visually recognized from the outside of the packaging body 50.

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

  Moreover, it is preferable that the site | part 51a1 (refer FIG. 4A) between the fastening tape 52 and the sealing part 53 among the opening bodies 51a of the package 50 is not fixed to the outer surface of the packaging sheet 51. That is, it is preferable that the overlapping portion 51 </ b> C of the packaging sheet 51 is not bonded 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 site | part 51a1 between the fastening tape 52 and the sealing part 53 becomes a passage of air, and the inside of the packaging sheet 51 is not sealed. Therefore, the diaper 1 is loosely packaged, and the diaper 1 is difficult to be folded. Moreover, by not sealing the inside of the packaging sheet 51, the packaging sheet 51 can be prevented from bursting, and unnecessary exposure of the diaper 1 can be prevented.

  Moreover, in this case, it is preferable that the diaper 1 is not folded together with the packaging sheet 51 like the package 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), the foreign substance and the diaper 1 are difficult to contact, and the sanitary state of the diaper 1 is maintained. Moreover, by providing the fastening tape 52 on the package 50, a part of the unsealed end 51a can be stopped by the fastening tape 52 while creating a passage for air between the pair of sealing portions 53, and foreign matter is mixed in. It can be said that it becomes difficult. However, not limited to the above, an 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 nonwoven 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 is obtained so that the inside diaper 1 is not contaminated from the outside, and the sanitary 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, the internal air can be extracted also from the surface of the portion 50A where the packaging sheet 51 is partially folded as shown in FIG. 8B. Therefore, it is possible to prevent the fastening tape 52 from coming off and the packaging sheet 51 from being opened due to air escaping only from the opening end 51 a 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 open end 51a. Therefore, it is preferable that the packaging sheet 51 is a non-woven fabric.

  Further, as described above, in the packaging sheet 51, the diaper 1 has both end portions 20A in the lateral direction of the belt portion 20 folded inward in the lateral direction (FIG. 5B), and is in a folding position F2 along the lateral direction. Thus, the absorbent main body 10 is folded in the vertical direction (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 part 20 can be expanded and contracted in the lateral direction, and when the belt part 20 is visually recognized from the outside of the packaging body 50, the contents of the packaging body 50 are easily recognized as the diaper 1. Therefore, by folding the belt part 20 inward in the lateral direction as described above, the size of the belt part 20 visually recognized from the outside of the package 50 can be reduced, and the diaper 1 is hardly recognized from the outside of the package 50. Become. Therefore, even a user who has a feeling of resistance to using the diaper 1 can easily carry the package 50.

  In the package 50 of the present embodiment, as shown in FIG. 5B and FIG. 7A, the non-skin side surfaces of the end portion 20 </ b> A in the lateral direction of the belt portion 20 face each other and are positioned on the skin side of the absorbent main body 10. As described above (that is, so as to be sandwiched between the absorbent main bodies 10), the lateral end 20A of the belt portion 20 is folded inward in the lateral direction. Therefore, the size of the belt part 20 visually recognized from the outside of the package 50 can be reduced, and the diaper 1 is hardly recognized from the outside of the package 50.

  Further, as in the modification of FIG. 7C, the lateral end 20 </ b> A of the belt portion 20 may be folded inward in the lateral direction so as to be positioned on the non-skin side of the absorbent main body 10. Also in this case, the belt that can be visually recognized from the outside of the package 50 by folding the absorbent main body 10 in the longitudinal direction at the folding position F2 so that the lateral end 20A of the belt 20 is inside. The size of the portion 20 can be reduced.

However, by folding the belt portion 20 as in 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 The folded state of the portion 20 is easily maintained.
Further, as shown in FIG. 7A, the upper end 10a on the abdomen side and the upper end 10b on the back side of the absorbent main body 10 are separated in the front-rear direction by the amount of the belt portion 20 sandwiched therebetween. Therefore, when the diaper 1 is worn, the user can easily pick the upper ends 10a and 10b of the absorbent main body 10, and the waistline opening BH can be easily widened.
Moreover, since a part of each belt part 20 overlaps, the length (L9 of FIG. 7A) of the belt part 20 folded inward in a horizontal direction becomes short compared with FIG. 7C. Therefore, the belt portion 20 is unlikely to cross the half-fold position F2 of the absorbent main body 10, and the half-fold state of the absorbent main body 10 is easily maintained.

  Moreover, in the diaper 1 (FIG. 1) of this embodiment, the connection parts 2 and 3 which connect the edge part of the absorptive main body 10 and the belt part 20 are toward the leg periphery opening side LH from the trunk periphery opening BH side. Inclined laterally outside. Therefore, as shown in FIG. 1 and FIG. 5A, the diaper 1 has a shape close to underwear such as shorts and briefs, and is easy to use even by a user who has a sense of resistance to using 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 which the fastening tape 52 is disposed is the front surface (FIG. 4A), and the opposite side is the back surface ( FIG. 4B). An overlapping portion 51 </ b> C of the fastening tape 52 and the packaging sheet 51 is disposed on the surface of the packaging body 50. Therefore, the diaper 1 in the package 50 is less visible on the front side than on the back side. Therefore, the upper end 10 </ b> A on the waistline opening BH side of the bifurcated absorbent main body 10 may be positioned on the front surface side of the packaging body 50, and the lower end portion 10 </ b> B may be positioned on the back surface side of the packaging body 50.

  By doing so, the belt part 20 connected to the upper end part 10A of the absorbent main body 10 and the connecting part 3 inclined obliquely, that is, the part that is easily recognized as the diaper 1 is located on the surface side. It becomes difficult to be visually recognized from the outside of the package 50. Therefore, it becomes difficult to recognize the contents of the package 50 as the diaper 1, and even a user who has a feeling of resistance to using the diaper 1 can easily carry the package 50.

  Further, by disposing 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 is folded is prevented while peeling the fastening tape 52. The belt part 20 and the connection part 3 are more difficult to be visually recognized from the outside of the package 50. However, not limited to the above, the upper end portion 10 </ b> A of the absorbent main body 10 may be located on the back side of the package 50.

  In addition, the shape of the diaper 1 which the package 50 includes is not restricted to the above. For example, one end portion of the absorbent main body is connected to the central portion of the abdominal belt portion along the lateral direction, and the other end portion of the absorbent main body is connected to the central portion of the back belt portion along the lateral direction. It may be a diaper in which both lateral portions of the belt portion and the back belt portion are connected. Also in this case, the contents of the package 50 are hardly recognized as the diaper 1 by folding the diaper 1 as described above and arranging the waist opening side portion of the absorbent main body on the surface side.

  In FIG. 5A, the folding position F1 of the belt portion 20 is inclined outward in the lateral direction from the waistline opening BH side toward the leg periphery opening LH side, but the folding position F1 of the belt portion 20 is not limited thereto. 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 not easily recognized as the diaper 1.

  Moreover, as shown to FIG. 4A, the horizontal direction of the diaper 1 in the packaging sheet 51 is along the direction (here 2nd direction orthogonal to a 1st direction) which cross | intersects the 1st direction of the package 50. As shown in FIG. Therefore, the folding position F2 along the lateral direction in which the absorbent main body 10 is folded in two is orthogonal to the folding positions F3 and F4 along the first direction of the packaging sheet 51.

Therefore, the packaging sheet 51 is difficult to receive the force of unfolding the diaper 1 folded inside, and the folded state of the packaging sheet 51 is easily maintained. In other words, since the absorbent main 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 sanitary state of the diaper 1 is maintained until the end. Be drunk.
Moreover, in the package 50 of this embodiment, since the site | part 51a1 between the fastening tape 52 and the sealing part 53 is not fixed, it may become easy to maintain the folding state of the packaging sheet 51 as mentioned above. preferable.

  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 develops the packaging sheet 51, it is difficult for a finger to enter the waistline opening BH. Therefore, the sanitary state of the diaper 1 is maintained without touching the skin side surface of the diaper 1 to the end. However, the present invention is not limited thereto, and the lateral direction of the diaper 1 may be along the first direction of the package 50.

  As mentioned above, although embodiment of this invention was described, said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. Further, the present invention can be changed or improved without departing from the gist thereof, and needless to say, the present invention includes equivalents thereof.
