The total length (length in the first direction D1) of the absorbent article 10 is not particularly limited, but can be 100 to 450 mm, preferably 140 to 360 mm, and more preferably 170 to 290 mm. Moreover, the width | variety (length of the 2nd direction D2) of the absorbent article 10 is preferable in it being 50-200 mm, and it is more preferable in it being 70-120 mm.

  3A to 3C show an individual packaging process of the individual absorbent article 100 according to an embodiment of the present invention. 3A and 3B are diagrams in which the individual absorbent article 100 is developed. As shown in FIG. 3A, the individual absorbent article 100 can be formed by overlapping a packaging sheet 20 on the absorbent article 10 on the surface sheet 3 side of the absorbent article 10. In the illustrated form, both the absorbent article 10 and the packaging sheet 20 have an elongated shape, and are arranged so that their longitudinal directions (first direction D1) substantially coincide with each other.

  The packaging sheet 20 is a sheet for at least partially wrapping the absorbent article 10 and accommodating the absorbent article 10. As the packaging sheet 20, a polyolefin-based film such as polypropylene and polyethylene, a film such as polyester and polyvinyl alcohol, a non-woven fabric, and a laminated non-woven fabric (including a polylaminated non-woven fabric) can be used. A film is preferable if design by printing is emphasized, and non-woven fabric is preferable if feeling or softness is emphasized. The packaging sheet 20 may be an untreated sheet, or when the anti-slip material 9 is provided on the back sheet 2 side of the absorbent article 10, at least the anti-slip material 9 of the packaging sheet 20. A parting treatment may be applied to the contacting portion. In that case, the below-mentioned peeling sheet 30 becomes unnecessary.

  In the embodiment shown in FIG. 3A, a release sheet 30 having a size and a shape that covers the anti-slip member 9 can be superimposed on the anti-slip member 9 side (back sheet 2 side) of the absorbent article 10. The material of the release sheet 30 is not particularly limited as long as it is a material that protects the slip stopper 9 and can be easily peeled off from the absorbent article 10 to expose the slip stopper 9 when the absorbent article 10 is used. Good. Specifically, the release sheet 30 is, for example, at least a portion in contact with the anti-deviation material 9 or at least the anti-deviation material 9 such as a silicone resin, a fluorocarbon resin, or a tetrafluoroethylene resin. It may be a paper or plastic sheet that has been release treated by coating or spray coating on the side that contacts it.

FIG. 3B shows a state after the absorbent article 10 is stacked on the packaging sheet 20 and one end of the packaging sheet 20 is folded back so as to wrap around one end 11 of the absorbent article. A first folded portion 21 is formed by folding the packaging sheet 20. As illustrated, the first folded portion 21 partially covers the back sheet 2 of the absorbent article 10. And the area | region which is not covered with the 1st folding | turning part 21 turns into an area | region exposed at the time of opening so that it may mention later. At the time of mounting, the exposed area on the back sheet 2 side is mounted on the mounted body so as to face the mounted body. Specifically, the length in which the packaging sheet 20 is folded (in FIG. 3B, the length in the first direction D1 of the first folded portion 21) is 35% or less, preferably 30% or less of the entire length of the absorbent article 10. And 25% or less. However, the length of the first folded portion 21 may be 1.5 cm or more, preferably 2 cm or more, and more preferably 3 cm or more so that the one end 11 of the absorbent article 10 can be gripped when worn. The first folded portion 21, 10～90Cm ² of the backsheet 2 side of the absorbent article 10, preferably cover the ² degree 20～60Cm.

  Note that the one end wrapped by the first folded portion 21 may be either end in the longitudinal direction of the absorbent article 10 (first direction D1). This is the same even when the front-rear direction when the absorbent article 10 is mounted is determined (for example, when it has a shape that is not line-symmetric with respect to the center line extending in the second direction D2).

  As shown in FIG. 3B, the side edge portion (edge portion in the second direction D2 in the drawing) 21a of the first folded portion 21 is joined to the packaging sheet 20 below, thereby forming the pocket 28. It's okay. With this configuration, the packaging sheets 20 (the first folded portion 21 and the region 23 adjacent to the packaging sheet 20) that wraps the one end 11 of the absorbent article 10 are not easily displaced from each other. Therefore, when holding the one end 11 of the absorbent article 10 at the time of mounting | wearing of the absorbent article 10, it can prevent that packaging sheet 20 comrades mutually slip and the absorbent article 10 falls out from the middle. Moreover, since the sealing performance of the individual absorbent article 100 is also enhanced, it is preferable from the viewpoint of hygiene.

  The joining of the side edge portion 21a of the first folded portion 21 may be formed by an adhesive such as an adhesive such as hot melt, heat seal, or ultrasonic seal, for example.

  In the illustrated form, the edge of the first folded portion 21 (the edge of one end of the packaging sheet 20) is substantially linear along the second direction D2. However, when the edge is not linear, for example, when the contour shape of the edge has irregularities or extends obliquely with respect to the second direction D2, the length of the first folded portion 21 is as follows. , The average of the longest length and the shortest length, or the area of the first folded portion 21 divided by the length of the second direction D2 of the packaging sheet, or the center of the second direction D2 It may be a part length.

  In the illustrated embodiment, the first folded portion 21 covers one end 11 of the absorbent article 10 in the longitudinal direction (the first direction D1), but the packaging sheet 20 is in the width direction of the absorbent article 10 (second The 1st folding | turning part 21 can also be formed by folding so that the end of direction D2) may be covered. In that case, after opening the individually coated absorbent article 100, the absorbent article 10 is covered by holding one end (one end in the second direction D2) of the absorbent article 10 in the width direction wrapped by the packaging sheet 20. It can be attached to the attached body.

  In FIG. 3C, the opposite end of the first folded portion 21 (the other end of the packaging sheet 20) is folded back as the second folded portion 22, and the absorbent article 10 is individually mounted. FIG. 4 is a cross-sectional view taken along the line II-II in FIG. 3C. As shown in FIG. 3C and FIG. 4, the second folded portion 22 is partially overlapped on the first folded portion 21. A tab tape 60 is provided at the end of the second folded back portion 22. When the tab tape 60 is opened and gripped and pulled, the second folded back portion 22 is pulled together and opened. Thereby, the individually-packed absorbent article 100 can be easily opened.

  The side edge portion in the first direction D1 of the individual absorbent article 100 shown in FIG. 3C is stacked using the same means as described for the joining of the side edge portion 21a of the first folded portion 21. 20 may be joined. Thereby, the individually coated absorbent article 100 can be sealed.

  As shown in FIG. 4, in the individual absorbent article 100, the release sheet 30 may be bonded to the second folded portion 22 of the packaging sheet 20 so as not to be peeled off. Thereby, when opening the 2nd folding | turning part 22, the peeling sheet 30 can be peeled from the slippage prevention material 9 with the 2nd folding | turning part 22, and the slippage prevention material 9 can be exposed. In the present specification, “unreleasable” refers to a state in which it cannot be removed by a normal opening operation or mounting operation. Further, “peelable” refers to a state that can be peeled off during normal opening work or mounting work.

  As shown in FIGS. 3B and 4, in the individual absorbent article 100, the first folded portion 21 does not overlap the slip stopper 9 and the release sheet 30. However, the first folded portion 21 may overlap the release sheet 30 or the slip stopper 9 and the release sheet 30 as long as it does not hinder the opening of the second folded portion 22. Moreover, the peeling sheet 30 may be comprised by two sheet so that the below-mentioned form (FIGS. 5A-5C, FIG. 6) may demonstrate.

  5A-5C illustrate the singulation process of a dressing absorbent article 200 according to another aspect of the present invention. 5A and 5B are diagrams in which the individual absorbent article 200 is developed. Similar to the above-described individual absorbent article 100 (FIGS. 3A to 3C, FIG. 4), the individual absorbent article 200 has the absorbent article 10 and the packaging sheet 220 superimposed on the top sheet 3 side of the absorbent article 10. It can be formed.

  The individual absorbent article 200 shown in FIGS. 5A to 5C is an individual absorbent article 100 (FIG. 3A to FIG. 3A) in that the absorbent article 10 is folded in two such that the topsheet 3 is on the inside. Different from 3C, Fig. 4). In the illustrated individual absorbent article 200, the absorbent article 10 is folded at a folding position extending along a short direction (second direction D2) perpendicular to the longitudinal direction (first direction D1). Thereby, the absorbent article 10 can be compactly packaged. That is, the area of top view of the individually coated absorbent article 200 can be reduced, which is convenient for carrying.

  As shown in FIG. 5A, the absorbent article 10 is folded at the other end 12 opposite to the one end 11 in the longitudinal direction (first direction D1) covered by the first folded portion 221 (FIG. 5B) described later. It is. The folding position of the absorbent article 10 can be selected according to the total length and thickness of the absorbent article 10, but the length from the other end 12 of the absorbent article 10 to the folding position is the same as that of the absorbent article 10. The total length is preferably less than 50%, more preferably 40% or less, and even more preferably 35% or less. By making the folding position as described above, it is possible to increase the area where the back sheet side of the absorbent article 10 is exposed when the individual absorbent article 200 is opened. Thereby, since the area of the surface which contacts a to-be-mounted body becomes large at the time of mounting | wearing, mounting | wearing of the absorbent article 10 becomes easier. From the viewpoint of stabilizing the folded state of the absorbent article 10, the length from the other end 12 of the absorbent article 10 to the folding position is 3 cm or more, preferably 5 cm or more, more preferably 6 cm or more. Can do. It is preferable that the folding position avoids a region corresponding to the body fluid discharge portion when the absorbent article 10 is mounted.

  The individual absorbent article 200 is also different from the individual absorbent article 100 (FIGS. 3A to 3C, FIG. 4) in that the configuration of the release sheet is different. Specifically, as shown in FIG. 5A, the individually coated absorbent article 200 includes two release sheets 230a and 230b (together with the packaging sheet 220 for covering the anti-slip member 9 of the absorbent article 10). Are also arranged). The release sheets 230a and 230b may be arranged in advance on the absorbent article 10 so as to cover the anti-slip member 9 of the absorbent article 10 before the absorbent article 10 is folded.

The first folded portion 221 is formed by folding back one end of the packaging sheet 220. The first folded part 221 partially covers the back sheet 2 side of the absorbent article 10 and partially covers the slip stopper 9. Here, the release sheet 230a disposed in advance on the packaging sheet 220 is interposed between the first folded portion 221 and the anti-slip member 9 so that the first folded portion 221 and the anti-slip member 9 do not contact directly. It is like that.

  FIG. 5C shows a state in which the end on the opposite side of the first folded portion 221 (the other end of the packaging sheet 20) is folded as the second folded portion 222 and the absorbent article 10 is individually mounted. FIG. 6 is a sectional view taken along line III-III in FIG. 5C. A tab tape 260 is provided at an end of the second folded back portion 222, and at the time of opening, the individual absorbent article 200 is easily opened by gripping the tab tape 260 and pulling the second folded back portion 222.

Similar to the individually coated absorbent article 100 (FIGS. 3A to 3C, 4) and the individually packed absorbent article 200 (FIGS. 5A to 5C, FIG. 6) described above, the individually coated absorbent article 300 includes the absorbent article 10 as described above. The packaging sheet 320 can be formed on the surface sheet 3 side of the absorbent article 10 in an overlapping manner. However, as shown in FIG. 7A, in the individually packaged absorbent article 300, the base sheet 50 is provided on the surface sheet 2 side of the absorbent article 10.

  The base sheet 50 is a sheet that comes into contact with the misalignment prevention material 9, and at least a part that comes into contact with the misalignment prevention material 9 is subjected to a release treatment, like the release sheets 30 and 230 described above. It is preferable that the base sheet 50 is a sheet having higher rigidity than the packaging sheet 220 because a stable opening operation can be performed when the individual absorbent article 300 is opened.

  The material of the base sheet is not particularly limited as long as it is a material that can be easily peeled off from the water-absorbent article when the water-absorbent article is used to expose the slip stopper. Specifically, semi-bleaching, high quality paper, glassine paper, or polypropylene, polyethylene, polyethylene terephthalate is used as a material, and a release treatment liquid such as silicone resin, fluorine resin, or tetrafluoroethylene resin is applied. Alternatively, it may be a paper or a plastic sheet which has been subjected to release treatment by spraying. The thickness of the base sheet is preferably 1 mm or less, and more preferably 100 μm or less.

  In addition, as shown in FIG. 7A, a breakable portion 325 is formed at the other end of the packaging sheet 320 of the individually coated absorbent article 300 on the opposite side to the one end where the first fold back 321 (FIG. 7B) described later is formed. Is formed. The easily breakable portion 325 is a linear weak portion such as a perforation, and the packaging sheet 320 is broken at the easily breakable portion 325 when opened.

  FIG. 7B shows a state after the absorbent article 10 and the packaging sheet 320 are stacked, and one end of the packaging sheet 320 is folded back so as to wrap around the one end 11 of the absorbent article 10. A first folded part 321 is formed by folding one end of the packaging sheet 320, and the first folded part 321 partially covers the back sheet 2 side of the absorbent article 10.

  In FIG. 7C, the individual absorbency obtained by further superimposing the base sheet 50 on the configuration (FIG. 7B) in which the absorbent article 10 and the packaging sheet 320 are superposed and one end of the packaging sheet 320 is folded back (FIG. 7B). The article 300 is shown. However, FIG. 7C shows a state where the packaging sheet 320 faces upward and the base sheet 50 faces downward. FIG. 8 is a cross-sectional view taken along the line III-III of FIG. 7C.

  In the individually packaged absorbent article 300, as shown in FIG. 7C, the width direction (the portion where the first folded portion 321 is overlapped) of the wrapping sheet 320 other than the portion where the wrapping sheet 320 is folded back (the first direction) The side edges 320a and 320a in the two directions D2) may be detachably bonded to the base sheet 50. Thereby, airtightness can be improved.

  Moreover, as shown to FIG. 7C, the edge part 328 of the side in which the 1st return part 321 is not formed of the packaging sheet 320 may be adhere | attached on the base material sheet 50 non-peelable. At the time of opening of the individually packaged absorbent article 300, a finger is inserted between the first folded part 321 and the base sheet 50, and the absorbent property is sandwiched between the first folded part 321 of the packaging sheet 320 and the area 323 adjacent thereto. The absorbent article 10 and the packaging sheet 320 can be peeled off from the base material sheet 50 in the first direction D1 by holding one end of the article.

  In the embodiment shown in FIG. 7C, the base sheet 50 has the length of the base sheet 50 in the package sheet 320 in any of the longitudinal direction (first direction D1) and the short direction (second direction D2). Has a size larger than the range in which it is placed. That is, the base sheet 50 has a size and a shape such that the absorbent article 10 does not protrude from the base sheet 50 in top view. However, the size of the base sheet 50 is not limited to that shown in the figure, and for example, the dimensions of the packaging sheet 320 and the base material in at least one of the longitudinal direction (first direction D1) and the short direction (second direction D2). The dimension of the sheet 50 may be the same, or the dimension of the packaging sheet 320 may be larger than the dimension of the base sheet 50.

  Next, the usage method of the individual absorbent article according to the present embodiment (the method of attaching the absorbent article) will be described more specifically. 9A to 9E show a method of using the individually-packed absorbent article 100 (FIGS. 3A to 3C) as an example. 9A to 9E are schematic cross-sectional views taken along line II-II of FIG. 3C. 9A to 9E, the detailed structure of the absorbent article 10 is omitted.

  First, in order to open the individually packaged absorbent article 100, as shown in FIG. 9A, the tab tape 60 is peeled off, and the second folded portion 22 is lifted and opened in the direction of the arrow together with the tab tape 60. As described above, since the release sheet 30 is adhered non-peelably to the second fold back portion 22, the release sheet 30 is also lifted along with the second fold back portion 22 and peeled off from the slip member 9 which was in contact (FIG. 9B). And when the 2nd folding | turning part 22 is opened, the back surface sheet 2 side of the absorbent article 10 will be partially exposed. Specifically, as shown in FIG. 9C, the slip stopper 9 of the absorbent article 10 can be exposed.

  As shown in FIG. 9C, one end 11 of the absorbent article 10 is wrapped in a packaging sheet 20. In other words, the first folded portion 21 of the packaging sheet 20 and the area 23 adjacent thereto are sandwiched. The user can hold the one end 11 of the absorbent article 10 sandwiched by the packaging sheet 20 from above and below (short arrows H and H), for example, with the thumb and other fingers.

  Subsequently, the absorbent article 10 is turned over and attached to the mounted body while holding the one end 11 of the absorbent article 10 sandwiched between the packaging sheets 20. FIG. 9D shows a state in which a part of the absorbent article 10 is placed on the mounted body S. As shown in FIG. 9D, the absorbent article 10 is placed so that the back sheet 2 side, that is, the slip stopper 9 faces the mounted body S such as shorts. After placing the absorbent article 10 with the packaging sheet 20 on the mounted body S, for example, the absorbent article 10 is pressed from the top of the packaging sheet 20 without directly touching the absorbent article 10, so The stopper 9 can also be securely adhered to the mounted body S.

  Thereafter, as shown in FIG. 9E, the packaging sheet 20 can be removed from the absorbent article 10.

  Thus, the individually coated absorbent article 100 is unsealed, the back sheet 2 side of the absorbent article 10 is exposed, and the absorbent article 10 is mounted such that the exposed side faces the mounted body S. Wearing can be performed by placing on the body S. Therefore, with this form, the operation | work which removes the absorbent article which was essential in the prior art can be omitted. In addition, since the user can wear the absorbent article 10 on the mountable body S by holding the end 11 wrapped in the packaging sheet 20, the user can wear the absorbent article without directly contacting the absorbent article, Sanitation is also preferable.

  The individual absorbent article 200 (FIGS. 5A to 5C) can be mounted in the same manner as the individual absorbent article 100, and has the same effect.

  10A to 10E show a method of using the individual absorbent article 300 (FIGS. 7A to 7C) (a method for attaching the absorbent article). 10A to 10E are schematic cross-sectional views taken along line II-II of FIG. 7C. 10A to 10E, the detailed structure of the absorbent article 10 is omitted.

  As shown in FIG. 10A, one end 11 of the absorbent article 10 housed in the individually packaged absorbent article 300 is in a state of being wrapped in a packaging sheet 320, that is, adjacent to the first folded portion 321 of the packaging sheet 320. It is in a state of being sandwiched between the region 323 and the region 323. The user can insert a finger between the packaging sheet 320 and the base sheet 50 and lift the end 11 of the absorbent article 10 sandwiched by the packaging sheet 20 in the direction indicated by the arrow. Then, as shown in FIG. 10B, one end 11 of the absorbent article 10 sandwiched by the packaging sheet 20 is gripped from above and below (short arrows H and H), for example, with a thumb and other fingers, 10 together with the packaging sheet 20 can be lifted from the base sheet 50 and peeled off.

  As described above, the packaging sheet 320 is bonded to the base sheet 50 so as not to be peeled off at the end edge portion 328 opposite to the side where the first folded portion 321 is formed. However, since the easily breakable portion 325 is provided in the vicinity of the end portion 328, the packaging sheet 320 can be separated at the easily breakable portion 325. FIG. 10C shows a state where the absorbent article 10 is peeled off from the base sheet 50 together with the packaging sheet 20 and the packaging sheet 320 is cut off at the easily breakable portion 325.

  In addition, the easily breakable part 325 is not provided, but the edge part 328 can be detachably bonded to the base sheet 50 similarly to the side edge part 320a. In that case, the entire packaging sheet 320 including the edge portion 328 can be peeled off.

  As shown in FIG. 10C, the absorbent article 10 peeled off from the base sheet 50 is in a state where the back sheet 2 side is exposed, that is, in a state where the slip stopper 9 is exposed. Therefore, the absorbent article 10 can be immediately mounted on the mounted body S without performing an additional work and without having to change the absorbent article 10.

  FIG. 10D shows a state in which a part of the absorbent article 10 is placed on the mounted body S such that the slip stopper 9 faces the mounted body S. Here, for example, the absorbent article 10 can be pressed without being touched directly from the top of the packaging sheet 20, and the entire slip stopper 9 can be securely adhered to the mounted body S.

  Thereafter, as shown in FIG. 10E, the packaging sheet 20 can be removed from the absorbent article 10.

  Thus, the individual absorbent article 300 can expose the back sheet 2 side of the absorbent article 10 by peeling the absorbent article 10 from the base material sheet 50. Immediately thereafter, the absorbent article 10 is placed on the mounted body S so that the exposed back sheet 2 side faces the mounted body S, whereby mounting can be performed. Therefore, with this form, the operation | work which removes the absorbent article which is essential in a prior art from a packaging sheet can be omitted. Further, if the base sheet 50 is fixed to another holding device or the like, the process from opening to mounting can be performed with one hand. Furthermore, the individual absorbent article 300 can also be attached without being in direct contact with the absorbent article 10, and is hygienic.

  One form of this invention may be a roll-shaped body containing multiple united absorbent articles provided with a base material sheet. This roll-shaped body can be obtained by connecting a plurality of individually absorbent articles 300 and winding them into a roll.

  FIG. 11 shows a roll-shaped body 500 including a plurality of individually absorbent articles 300 ′ as an example. In the roll-like body 500, the configuration of each individually absorbent article 300 ′ is the same as that of the above-described individual absorbent article 300 (FIGS. 7A to 7C and FIG. 8). The long base sheet 550 common to the articles 300 'is used, and the base sheet 550 is wound so as to be on the outside. In other words, the base sheet 550 is continuously connected in a band shape among the plurality of individual absorbent articles 300 '. In the illustrated form, the longitudinal direction of the plurality of individually absorbent articles 300 ′ is substantially coincident with the longitudinal direction of the base sheet 550 (the direction in which the base sheet 550 is pulled out during use). The method of opening and mounting the individually absorbent article 300 ′ is as described with reference to FIGS. 10A to 10E.

  Thus, by connecting the individually packaged absorbent articles into the roll-shaped body 500, the absorbent articles can be compactly accommodated. In addition, since the individually coated absorbent article 300 'is wound so that the base sheet 550 is on the outer side until immediately before use by forming the roll-shaped body 500, the individually coated absorbent article 300' is used before being used. It can be avoided that the packaging sheet 320 'side is exposed. In addition, since the individual absorbent articles 300 'stacked in a wound state are held against each other, as shown in FIG. 7C, the side edges of the packaging sheet 320' (320a in FIG. 7C). The portion shown) may not be releasably adhered to the base sheet 550, and the adhesion of the side edge may be omitted.

  Moreover, if the roll-shaped body 500 is hold | maintained with a holding | maintenance apparatus etc., when peeling the absorbent article 10 from the base material sheet 550, it can peel easily with one hand.

  FIG. 12 shows a roll-like body 600 including a plurality of individually absorbent articles 300 ″ as another form of the roll-like body. Similar to the roll-shaped body 500, the roll-shaped body 600 uses a long base sheet 650 common to the plurality of individually absorbent articles 300 '' as the base sheet. However, in the roll-shaped body 600 shown in FIG. 12, the longitudinal direction of the plurality of individually absorbent articles 300 ″ is perpendicular to the longitudinal direction of the base sheet 650 (the direction in which the base sheet 550 is pulled out during use). It differs from the roll-shaped body 500 by the point which has become.

  In the roll-shaped body 600 shown in FIG. 12, the first folded portion 321 ′ ′ of the packaging sheet 320 ′ ′ of the individually packaged absorbent article 300 ′ ′ is folded so as to cover one end in the short direction of the absorbent article 10. ing. In use, one end of the absorbent article 10 in the lateral direction is held together with the packaging sheet 320 '' to peel off the absorbent article 10 from the base sheet 650, and immediately thereafter, the back sheet side of the absorbent article 10 is attached The absorbent article 10 can be attached to face the body.
