  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, unless otherwise specified, the same or corresponding components may be denoted by the same reference numerals and description thereof may be omitted.

  The packaging sheet according to this embodiment is a sheet for packaging and storing a planar article. The packaging sheet by this form can be used suitably as a packaging sheet which packages absorbent articles, such as a sanitary napkin, a panty liner, and an incontinence pad, as a planar article. Therefore, in the following, the packaging sheet for packaging the absorbent article and the packaging absorbent article will be mainly described.

  In FIG. 1, the figure which looked at the state which mounted the absorbent article 1 on the packaging sheet 10 from the upper surface is shown. This FIG. 1 is also a figure which shows the state which expand | deployed the package absorbent article 100. FIG. In the illustrated form, the packaging sheet 10 has a rectangular elongated shape, and the first direction D1 in FIG. 1 is the longitudinal direction. However, the shape of the packaging sheet 10 is not limited to an elongated shape, and the length of the packaging sheet 10 in the first direction D1 and the length of the second direction D2 orthogonal to the first direction D1 may be substantially the same. Good. The packaging sheet 10 has a dimension in which the length in the first direction D1 is 10 to 39 cm, preferably 20 to 32 cm, and the length in the second direction D2 is 3 to 18 cm, preferably 10 to 14 cm. It may be.

  As the packaging sheet 10, a polyolefin film such as polypropylene or polyethylene, a film such as polyester or polyvinyl alcohol, a nonwoven fabric, a laminated nonwoven fabric (including a polylaminated nonwoven fabric), paper, or the like can be used. A film is preferred if importance is placed on the design by printing, etc., and a nonwoven fabric is preferred if importance is placed on the texture or soft feeling.

  The absorbent article 1 has a main body (absorbent article main body) having a liquid-impervious back sheet 2, a liquid-permeable top sheet 3, and an absorbent body 4 provided between the two sheets 2 and 3. 8 and. In the form of FIG. 1, the absorbent article 1 has a long and narrow shape in the first direction D1 as a whole in a top view, but the shape of the absorbent article 1 is not limited to the illustrated elongated shape, The shape in which the first direction D1 and the second direction D2 orthogonal to the first direction D1 have substantially the same length may be used.

  In the illustrated form, the absorbent article 1 is symmetrical with respect to both the center line along the longitudinal direction (first direction D1) and the center line along the width direction (second direction D2). However, the shape may be asymmetric with respect to either the longitudinal direction or the width direction. In that case, the direction of the longitudinal direction and the width direction when the absorbent article 1 is arranged on the packaging sheet 10 is not limited.

  As the back sheet 2 of the absorbent article 1, a sheet material having at least water shielding properties such as an olefin resin sheet such as polyethylene or polypropylene can be used. A laminated nonwoven fabric obtained by laminating a nonwoven fabric on a polyethylene sheet or the like, or a laminated sheet of nonwoven fabric that is substantially impervious to liquid by interposing a waterproof film can be used. Further, it is more desirable to use a material having moisture permeability from the viewpoint of preventing stuffiness. As such a water-impervious / breathable sheet material, a sheet obtained by melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet and then stretching it in a uniaxial or biaxial direction can be obtained. A porous sheet can be used.

  The top sheet 3 is a liquid-permeable sheet that quickly permeates body fluids such as menstrual blood, venom, and urine. As the surface sheet 3, a porous or non-porous nonwoven fabric, a porous plastic sheet, or the like is preferably used. Examples of the material fibers constituting the nonwoven fabric include olefins such as polyethylene and polypropylene, synthetic fibers such as polyester and polyamide, regenerated fibers such as rayon and cupra, and blended fibers thereof, and natural fibers such as cotton alone or Two or more types can be used in combination. Moreover, the composite fiber which combined the synthetic fiber from which melting | fusing point differs can also be used.

  The absorbent body 4 interposed between the back sheet 2 and the top sheet 3 is not limited as long as it is a material that can absorb and retain body fluid, but preferably contains cotton-like pulp and a water-absorbing polymer. As the water-absorbing polymer, a superabsorbent polymer (SAP), a superabsorbent fiber (SAF), and a combination thereof can be used. Examples of pulp include cellulose fibers such as chemical pulp obtained from wood and dissolved pulp, and artificial cellulose fibers such as rayon and acetate. As raw materials for chemical pulp, hardwood, softwood, etc. are used, but softwood is preferably used because of its long fiber length. Further, the absorbent body 4 may be mixed with synthetic fibers.

  Further, the absorbent article 1 may be provided with a pressing groove (also referred to as fit embossing) 5 that is recessed from the top sheet 3 side to the back sheet 2 side.

  The thickness of the absorbent article 1 can be in the range of 1 to 10 mm, and is preferably in the range of 1 to 4 mm. This thickness does not have to be uniform over the entire surface of the absorbent article 1, and by changing the thickness of the absorbent body 4, the central portion of the main body 8 in the first direction D <b> 1, the portion corresponding to the groove of the flange portion, etc. It can also be made into a structure.

  As shown in FIG. 1, the packaging sheet 10 has one end 18 and the other end 19 in the first direction (longitudinal direction) D1. The first region 11 including the one end 18 and the second region 12 including the other end 19 are included. When packaging the absorbent article 1 with the packaging sheet 10, the first region 11 and the second region 12 can be folded at a first fold line 21 and a second fold line 22, respectively. The first fold line 21 and the second fold line 22 are valley fold lines, whereby both the first fold line 21 and the second fold line 22 can be folded to the side on which the absorbent article 1 is placed. it can.

  In the illustrated form, the absorbent article 1 has a size exceeding the first fold line 21 and the second fold line 22. Therefore, when the packaging sheet 10 is folded at the first fold line 21 and the second fold line 22 as described above, the absorbent article 1 is also in a position corresponding to the first fold line 21 and the second fold line 22. Fold with 10 The absorbent article 1 may be sized to fit within the third region 13 between the first fold line 21 and the second fold line 22, and in that case, the absorbent article 1 is a packaging sheet. It is packaged by the packaging sheet 10 without being folded together.

  In the illustrated form, the absorbent article 1 is placed on the packaging sheet 10 so that the back sheet 3 side faces the packaging sheet 10, but is placed on the packaging sheet so that the top sheet 2 side faces the packaging sheet 10. It may be placed.

  As shown in FIG. 1, a third fold line 23 that can be mountain-folded may be provided in the second region 12 of the packaging sheet 10. By folding the third fold line 23 into a mountain, a folded region 12A and a non-folded region 12B described later can be formed. The first region 11 may be provided with a fourth fold line 24 that can be folded in a mountain. By folding the fourth fold line 24 in a mountain, a folded region 11A and a non-folded region 11B described later can be formed. The form in which the fourth fold line 24 is formed corresponds to the second form described above.

  The figure which looked at the state in the middle of folding the packaging sheet 10 in FIG. 2 in the cross section along the II line | wire of FIG. 1 is shown. FIG. 2 is also a view showing the packaged absorbent article 100 being opened. As shown in FIG. 2, the absorbent article 1 is placed on the first fold line 21 and the second fold line 22 respectively on the first region 11 and the second region 12 on both sides in the longitudinal direction of the third region 13 in the center. Folded on the side where it is placed.

  Moreover, the 2nd area | region 12 is arrange | positioned inside the 1st area | region 11 in the state in which the absorbent article 1 was packaged. That is, the absorbent article 1 is packaged by overlapping the first region 11 and the second region 12.

  As shown in FIG. 2, the second region 12 is folded at the third fold line 23 to form a folded region 12A and a non-folded region 12B that is not folded. Thereby, the other end 19 of the packaging sheet 10 faces outward in the longitudinal direction. Thereby, the user can easily hold the other end 19. Further, the first region 11 is also folded at the fourth fold line, and a folded region 11A and a non-folded region 11B that is not folded are formed. Thereby, since the one end 18 of the packaging sheet 10 also faces the outer side in the longitudinal direction, the user can easily grip the one end 18.

  FIG. 3 shows a top view of the packaged absorbent article 100 in which the packaging sheet 10 shown in FIGS. 1 and 2 is folded together with the absorbent article 1 and the absorbent article 1 is packaged. As shown in FIG. 3, in the packaging absorbent article 100, both the folded region 11 </ b> A of the first region 11 and the folded region 12 </ b> A of the second region 12 are exposed. That is, the first fold line 21 does not overlap the other end 19. Thereby, the one end 18 and the other end 19 of the packaging sheet 10 are exposed. Therefore, at the time of opening, the user can hold each end of one end 18 and both ends 19 with his / her left and right hands, for example, with the thumb of each hand and the other fingers. When both ends 18 and 19 are gripped, for example, as shown by the arrows in FIG. 3, the packaged absorbent article 100 can be opened at once by pulling each other outward in the first direction D1 (longitudinal direction). And the packaging sheet 10 can be expand | deployed with opening of the packaging absorbent article 100, and the absorbent article 1 accommodated can be made to appear. Thus, in this embodiment, unlike the conventional case, a complicated opening operation of expanding the upper region of the packaging sheet and expanding the lower region in some cases is not necessary.

  Moreover, the packaging absorbent article 100 by this form can be opened, without touching the absorbent article 1 packaged inside. Therefore, it is preferable also in terms of hygiene. Furthermore, since the pouch tape provided for easily grasping the upper part of the packaging sheet is not necessary, the manufacturing cost can be reduced.

  As shown in FIG. 3, after the packaging sheet 10 is folded, the edge of the packaging sheet 10 in the second direction D <b> 2 can be sealed by the weak seal portion 31. The weak seal portion 31 is a portion that is sealed so as to be able to be opened, that is, a relatively weakly sealed portion that can be peeled off by a user by a normal opening operation. The weak seal portion 31 may be formed by, for example, heat sealing, ultrasonic sealing, adhesive, or the like.

  As described above, the packaging sheet 10 according to the present embodiment is folded by three or more fold lines. In the packaging state as shown in FIG. 3, the number of stacked sheets varies depending on the location at the edge of the packaging sheet 10. For example, in an area close to the first fold line 21, two sheets of the non-folded area 11 </ b> B of the first area 11 and the third area 13 are stacked. However, under the folded area 11A of the first area 11, there are five sheets of a non-folded area 11B, a folded area 12A of the second area 12, a non-folded area 12B of the second area 12, and a third area 13. Will be stacked. Therefore, when the edge of the packaging sheet 10 in the second direction D2 is sealed with a pressure-bonding roll, the region where the number of stacked sheets is large tends to be hard. Therefore, a region where the number of stacked layers is small can be sealed by additionally performing pressure bonding or the like. Further, the pressure of the roll can be changed for each region where the number of stacked layers is different.

  When the weak seal portion 31 is sealed by pressure bonding, a motif 33 such as a dot or a floral pattern may be formed as shown in FIG.

  The absorbent article 1 may be provided with a slip stopper for fixing the absorbent article 1 to shorts or the like when the absorbent article 1 is mounted on the back sheet 2 side. The slip stopper may be an adhesive layer containing a styrene polymer, a tackifier, a plasticizer, or the like, or a non-adhesive layer containing rubber or the like.

  When the back sheet 2 is provided with an adhesive slip stopper, the absorbent article 1 is placed on the packaging sheet 10 so that the back sheet 2 side faces the packaging sheet 10 as shown in FIG. The absorbent article 1 and the packaging sheet 10 can be adhered (removably bonded). As shown in the figure, in the form in which the packaging sheet 10 is folded together with the absorbent article 1 and the absorbent article 1 is packaged, if the absorbent article 1 and the packaging sheet 10 are adhered, the packaging absorbent article 100 is opened. Sometimes, the absorbent article 1 can be developed following the packaging sheet 10 with the development of the packaging sheet 10.

  When the absorbent article 1 and the packaging sheet 10 are adhered, a mold release process can be performed on at least a region of the packaging sheet 10 corresponding to the slip stopper of the absorbent article 1. Thereby, after opening and expanding the packaging sheet 10, the absorbent article 1 can be easily peeled off from the packaging sheet 10 and taken out. In addition, a release sheet for covering and protecting at least the slip prevention material of the absorbent article 1 is provided between the absorbent article 1 and the packaging sheet 10, and the release sheet and the packaging sheet 10 are bonded so as not to be peeled off. You can also let them.

  In FIG. 3, the length d1 in the first direction D1 of the folded region 11A of the first region 11 placed on the outside is preferably about 5 to 40 mm, and more preferably about 10 to 25 mm. In addition, the length d2 of the portion where the folded region 12A of the second region 12 disposed below the first region 11 is exposed in the packaged state is preferably about 5 to 40 mm, and about 10 to 25 mm. Is more preferable. Thereby, both ends 18 and 19 of the packaging sheet 10 can be easily gripped. As will be described later, when the contour of the edge of the folded region 11A (the contour of the one end 18) is not a straight line parallel to the second direction D2, the length d1 of the folded region 11A in the first direction D1 is It can be the length in the center of the two directions D2. The same applies to the length d2 of the folded region 12A in the first direction D1.

  The modification of the packaging sheet 10 of the packaging absorbent article 100 shown in FIGS. 1-3 is shown in FIG.4 and FIG.5. 4 is different from the packaging sheet 10 shown in FIGS. 1 to 3 in that the second region 12 has pockets 35. As shown in FIG. 4, the side edges of the folded portion 12 </ b> A and the non-folded portion 12 </ b> B of the second region 12 of the packaging sheet 10 may be sealed by a strong seal portion 32. The strong seal portion 32 is a seal that cannot be peeled off by a normal opening operation. As with the weak seal portion 31, the strong seal portion 32 can be formed by heat sealing, ultrasonic sealing, adhesive, or the like. Since the side edge of the second region 12 is adhered by the strong seal portion 32 that cannot be peeled off, the weak seal portion 31 is peeled off after opening and expanding the packaging sheet 10, but the seal of the strong seal portion 32 is It is maintained without peeling. Thereby, a bag-shaped space is formed by the folded portion 12A and the non-folded portion 12B, which becomes a pocket.

  Also in the form of FIG. 5, the side edges of the folded region 12A and the non-folded region 12B of the second region 12 are sealed by the strong seal portion 32, so that the pocket 35 is formed. 4 and the side edge of the non-folded portion 12B are different from the embodiment of FIG. 4 in that they are not partially sealed by the strong seal portion 32. That is, as shown in FIG. 5, at the end of the second region 12 (the end of the folded region 12A opposite to the third fold line 23), the folded region 12A and the non-folded region 12B are bonded so as not to be peeled off. They are not bonded and are bonded by the weak seal portion 31. Therefore, when grasping and pulling the other end 19 in order to unfold the packaging sheet 10, the end of the second region 12 is easily peeled off with a small force at the beginning of pulling. Therefore, the packaging sheet 10 can be developed by easily pulling the other end 19 of the packaging sheet 10 while having the configuration of the pocket 35.

  As shown in FIG. 5, when there is a portion where the strong seal portion 32 is not formed at the side edge of the folded region 12A of the second region 12, the portion where the strong seal portion 32 is not formed is the edge (others) of the folded region 12A. It may be a portion of about 5 to 15 mm, preferably about 10 mm from the edge 19 of the end 19.

  As described above, when the pocket 35 is formed in the second region 12, the length in the longitudinal direction (first direction D1) of the folded region 12A of the second region 12 is 25 mm or more, preferably 35 mm or more. it can. In that case, it is preferable that the length in the longitudinal direction of the folded region 12A does not exceed the length in the longitudinal direction of the non-folded region 12B.

  4 and 5, since the side edges of the folded region 12A and the non-folded region 12B of the second region 12 are bonded by the strong seal portion 32, the opening operation and the unfolding operation of the packaging absorbent article are performed. After that, the pocket 35 is held without breaking. Therefore, as shown in FIG. 6, for example, the used absorbent article 1 ′ can be rolled up and stored in the pocket 35. Thereby, disposal of used absorbent article 1 'becomes easy.

  7A and 7B show a modification of the packaging sheet 10 of the packaging absorbent article 100 (FIGS. 1 to 3). 7A is a view of the state in which the packaging sheet 10 is unfolded as viewed from above, and FIG. 7B is a view of the state in which the packaging sheet 10 is folded and the absorbent article 1 is packaged as viewed from above. This form is different from the packaging sheet 10 shown in FIGS. 1 to 3 in that the shape of the folded region 11A of the first region 11 of the packaging sheet 10 and the folded region 12A of the second region 12 are triangular. The triangular shape of the folded region 11A and the folded region 12A in this embodiment is an isosceles triangle having a vertex at the center line extending along the longitudinal direction (second direction D1). It does not have to be on the line. In the present embodiment, both the folded region 11A and the folded region 12A have a triangular shape, but at least one of the folded region 11A and the folded region 12A may be a triangle.

  8A and 8B show another modification of the packaging sheet 10 of the packaging absorbent article 100 (FIGS. 1 to 3). FIG. 8A is a view of the state in which the packaging sheet 10 is unfolded as viewed from above, and FIG. 8B is a view of the state in which the packaging sheet 10 is folded and the absorbent article 1 is packaged as viewed from above. This form is different from the packaging sheet 10 shown in FIGS. 1 to 3 in that the folded region 11A of the first region 11 of the packaging sheet 10 and the folded region 12A of the second region 12 are partially circular. In this embodiment, both the folded region 11A and the folded region 12A have a partial circle shape, but at least one of the folded region 11A and the folded region 12A can be a partial circle.

  As shown in FIGS. 7A and 7B and FIGS. 8A and 8B, the folded region 11A of the first region 11 and the folded region 12A of the second region 12 of the packaging sheet 10 are in the second direction near the center of the second direction D2. By having a shape that projects to the outside of D1, each end 18 and 19 of the packaging sheet 10 can be easily grasped when opened. Further, in the packaging state, the edge of the packaging sheet 10 in the second direction D2 may be sealed by the weak seal portion 31, but the shape of the folded region 11A of the first region 11 and the folded region 12A of the second region 12 may be triangular or By setting it as a partial circle, the area | region where the return area | region 11A and the return area | region 12A are sealed by the weak seal | sticker part 31 can be made small. Therefore, the packaging sheet 10 can be expanded more easily and with a smaller force.

  The shapes of the folded region 11A and the folded region 12A are not limited to a rectangle (FIG. 1), a triangle (FIGS. 7A and 7B), and a partial circle (FIGS. 8A and 8B). The shape of the folded region 11A and the folded region 12A may be a quadrilateral other than a rectangle, for example, a square, a trapezoid, a parallelogram, etc., or a pentagon, a hexagon, or the like. Moreover, a partial ellipse may be sufficient and the wavy shape in which an outline has an unevenness | corrugation may be sufficient. However, a shape that does not protrude from the end in the second direction D2 when folded is preferable.

  Further, the length in the second direction D2 of the edge on the fourth fold line 24 side of the folded region 11A in the first region 11 is the second direction of the edge on the fourth fold line 24 side in the non-folded region 11B. It can also be shorter than the length of D2. The same applies to the folded region 12A in the second region 12.

  In FIG. 9, the further modification of the packaging sheet 10 is shown. In the form shown in FIG. 9, the folded area 11A of the first area 11 and the folded area 12A of the second area 12 are colored with different colors. By being colored, the ends 18 and 19 to be grasped are easily understood at a glance, and the user can perform the opening operation without hesitation. Note that both the folded region 11A and the folded region 12A may be colored, or only one of them may be colored. For example, the folded area 11A can be light green, and the folded area 12A can be light blue. Only a part of the folded area 11A (or the folded area 12A) may be colored. In addition, symbols and characters may be applied to the folded region 11A and the folded region 12A.

  FIG. 10 also shows a modification of the packaging sheet 10. In the form shown in FIG. 10, an embossed portion E is formed in the vicinity of the center in the second direction D2 in each of the folded region 11A of the first region 11 and the folded region 12A of the second region 12. Since the embossed portion E is formed, the rigidity can be increased, so that it is easy to grip at the time of opening, and damage due to pulling at the time of opening can be prevented.
