Description

Technical Field

[0001] The present disclosure relates to a package for absorbent articles.

Background Art

[0002] Generally, absorbent articles such as sanitary napkins and light incontinence products are used by attaching them to underwear. When removing a used absorbent article from underwear, since the removal operation is performed with both hands, it is difficult to perform the removal operation while gripping the individual package of the newly used absorbent article.

[0003] As a prior art for performing the removal and attachment operations of absorbent articles using both hands, for example, as described in Patent Document 1, a package for absorbent articles that can be attached to a toilet wall or the body of the wearer is disclosed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the case of absorbent articles such as those in Patent Document 1, there is a risk that the package temporarily attached to the wall or the body, or the absorbent article attached to this package, may peel off and fall from the wall or the body, causing concern in terms of hygiene.

[0006] In general, used absorbent articles are rolled up and wrapped in individual packages for disposal. However, there is a risk that the absorption surface of body fluid may be exposed to others' eyes from the side of the absorbent article, or that the rolled-up used absorbent article may open, which may spoil the mood of the cleaner or the next user. Also, if toilet paper is wrapped around the used absorbent article many times to enhance concealment, the volume increases and the trash can is likely to be filled.

[0007] Therefore, an object of the present disclosure is to provide an absorbent article package capable of hygienically and easily replacing an absorbent article and disposing of a used absorbent article in a highly concealable state.

Means for Solving the Problems

It has an absorbent article extending in the longitudinal direction, a sheet one-side surface detachably adhered via the first adhesive layer to the non-skin surface side of the backsheet of the absorbent article, and a second adhesive layer provided on the sheet other-side surface opposite to the sheet one-side surface. A first individual packaging sheet capable of individually packaging the absorbent article by folding back the absorbent article so as to enclose the absorbent article in a state where the absorbent article is adhered to the sheet one-side surface, and a second individual packaging sheet detachably adhered via the second adhesive layer to the sheet other-side surface of the first individual packaging sheet. The first individual packaging sheet has a sheet body and a bag-shaped portion integrally provided on the sheet one-side surface side of one end of the sheet body in the longitudinal direction and opening toward the other side in the longitudinal direction, and is any one of a colored non-woven fabric, a resin film, paper, or a laminate of two or more of these.

[0009] A second aspect of the present invention is the absorbent article package according to the first aspect, wherein the bag-shaped portion of the first individual packaging sheet is formed by continuously extending from one end of the sheet body in the longitudinal direction and folding back toward the sheet one-side surface side.

[0010] A third aspect of the present invention is the absorbent article package according to the first aspect or the second aspect, wherein the length of the bag-shaped portion of the first individual packaging sheet in the longitudinal direction is shorter than half the length of the sheet body in the longitudinal direction.

[0011] A fourth aspect of the present invention is an absorbent article package according to any one of the first to third aspects above, wherein the length of the sheet body of the first packaging sheet in the short side direction is longer than the length of the absorbent article in the short side direction.

[0012] A fifth aspect of the present invention is an absorbent article package according to any one of the first to fourth aspects above, wherein the second packaging sheet is a non-woven fabric, a resin film, paper, or a laminate of two or more of these, which is a different color from the first packaging sheet.

[0016] In the description of this specification, the longitudinal direction of the absorbent article package 10 is the direction extending across the front and back of the wearer when the absorbent article 11 is worn, and in the figure, it is the direction along the arrow X. Also, the lateral direction of the absorbent article package 10 is a direction transverse or orthogonal to the longitudinal direction, and in the figure, it is the direction along the arrow Y. Further, the skin side of the absorbent article package 10 indicates the direction (the direction indicated by the arrow Z in the figure) facing the wearer's skin side in the thickness direction of the absorbent article 11 when worn, and the non-skin side of the absorbent article package 10 indicates the direction (the direction opposite to the direction indicated by the arrow Z in the figure) facing the side opposite to the wearer's skin side (the underwear 40 side) when the absorbent article 11 is worn. Body fluid refers to a liquid discharged from the body to the outside, such as urine, blood, and moisture in soft feces. Furthermore, examples of the absorbent article 11 include, but are not limited to, sanitary napkins and products for preventing light leakage, and other absorbent articles may also be used.

[0017] FIG. 1 is a plan view of an absorbent article package 10 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view taken along the line II-II of FIG. 1. FIG. 3 is a cross-sectional view taken along the line III-III of FIG. 1.

[0018] As shown in FIGS. 1 to 3, an absorbent article package 10 according to an embodiment of the present invention is, for example, a package for a sanitary napkin, and includes an absorbent article 11, a first packaging sheet 12 capable of packaging the absorbent article 11, and a second packaging sheet 13.

[0019] The absorbent article 11 is an article attached to the undergarment 40 for absorbing body fluids, and includes a liquid-permeable topsheet 14 on the skin side, a liquid-impermeable backsheet 15 on the non-skin side, an absorber 16 disposed between the topsheet 14 and the backsheet 15, and a first adhesive layer 17 provided on the non-skin side of the backsheet 15.

[0020] Preferably, the longitudinal dimension L1 of the absorbent article 11 is 100 mm or more and 800 mm or less, and the lateral dimension L2 of the absorbent article 11 is 50 mm or more and 500 mm or less. By adjusting the dimensions of the absorbent article 11 within the above ranges, an absorbent article 11 suitable for sanitary napkins and incontinence products can be obtained.

[0021] Further, in order to prevent lateral leakage of the body fluids excreted by the wearer, as shown in FIG. 2, the absorbent article 11 may be provided with a pair of three-dimensional gathers 18c having elastic members for three-dimensional gathers on the topsheet 14 along the longitudinal direction of the absorbent article 11. The three-dimensional gather sheet 18 constituting the three-dimensional gather 18c has an outer end portion 18a in the width direction fixed to the outer end portion in the width direction of the backsheet 15, and a portion 18b inside the outer end portion 18a in the lateral direction fixed to the outer end portion in the width direction of the topsheet 14. A region 18c inside the portion 18b fixed to the topsheet 14 in the lateral direction (toward the center of the absorbent article 11) serves as a free end. The region 18c inside the portion 18b fixed to the topsheet 14 in the lateral direction (the region on the free end side) of the three-dimensional gather sheet 18 functions as a three-dimensional gather 18c extending in the longitudinal direction. By providing the elastic member for three-dimensional gathers along the longitudinal direction, the three-dimensional gather 18c has standing properties and can be deformed according to the body shape of the wearer.

[0022] As the elastic member for three-dimensional gathers, for example, a thermal bond nonwoven fabric, a spunbond nonwoven fabric, a polyethylene film, or a sheet formed by combining and joining these sheets can be used. From the viewpoints of strength and processability, the basis weight of the three-dimensional gather 18c is 13 g / m 2 or more and 20 g / m 2The following are preferred. In this embodiment, the absorbent article 11 is provided with the three-dimensional gathers 18c, but the three-dimensional gathers 18c may not be provided.

[0023] The topsheet 14 may be formed from a base material having liquid permeability that allows body fluid to move to the absorbent body 16. Examples of the base material include, for example, non-woven fabrics such as air-through non-woven fabric, thermal-bonded non-woven fabric, spunbond non-woven fabric, and composite non-woven fabric obtained by laminating thermal-bonded / spunbonded non-woven fabric. Further, the topsheet 14 may be embossed or perforated on the surface in order to improve liquid permeability. As a method for performing these embossing and perforating processes, known methods can be implemented without limitation. Further, in order to reduce irritation to the skin, the topsheet 14 may contain lotion, antioxidant, anti-inflammatory component, pH adjuster, antibacterial agent, humectant, and the like.

[0024] The basis weight of the topsheet 14 is preferably 15 g / m 2 or more and 40 g / m 2 or less, more preferably 19 g / m 2 or more and 35 g / m 2 or less, from the viewpoints of strength, processability, and liquid rewet amount. The shape of the topsheet 14 is not particularly limited, but it may be a shape that covers the absorbent body 16 and is necessary for guiding body fluid to the absorbent body 16 so as not to leak.

[0025] Further, in order to facilitate attachment of the second adhesive layer 23 (described later) of the first packaging sheet 12 onto the topsheet 14 of the used absorbent article 11 when replacing the absorbent article 11 described later, a pair of liquid-impermeable side sheets 19 are preferably provided at both longitudinal ends of the absorbent article 11 on the skin side of the topsheet 14. The longitudinal dimension of each of the side sheets 19 is preferably 10 mm or more and 30 mm or less. In this embodiment, the absorbent article 11 is provided with the side sheets 19, but the side sheets 19 may not be provided.

[0026] The backsheet 15 may be formed using a liquid-impermeable base material that prevents the body fluid held by the absorber 16 from wetting the clothing, and a plastic film such as a liquid-impermeable polyethylene film that is breathable or non-breathable can be used.

[0027] From the viewpoints of strength and processability, the basis weight of the backsheet 15 is preferably 15 g / m 2 or more and 60 g / m 2 or less, more preferably 20 g / m 2 or more and 40 g / m 2 or less. To make the backsheet 15 breathable, for example, a filler may be blended into the resin film of the base material, or the backsheet 15 may be embossed. Examples of the filler include calcium carbonate, and the blending method can be carried out without limitation using known methods.

[0028] A first adhesive layer 17 is provided on the non-skin side of the backsheet 15. The first adhesive layer 17 is provided for attaching the absorbent article 11 to the wearer's underwear. As the adhesive for forming the first adhesive layer 17, known materials can be used.

[0029] The absorber 16 contains absorbent fibers as a base material and a superabsorbent polymer (SAP). The dimension of the longest width in the longitudinal direction of the absorber 16 is preferably 100 mm or more and 800 mm or less, more preferably 150 mm or more and 500 mm or less. Also, the dimension of the longest width in the short transverse direction of the absorber 16 is preferably 50 mm or more and 500 mm or less, more preferably 70 mm or more and 105 mm or less.

[0030] The absorbent fibers of the absorber 16 are not particularly limited as long as they are generally used in absorbent articles such as sanitary napkins, paper diapers, urine pads, etc. For example, fluff pulp, cotton, rayon, acetate, tissue, absorbent paper, hydrophilic non-woven fabric, etc. can be mentioned. Among these, from the viewpoint of absorbency, it is preferable to use fluff pulp. Examples of fluff pulp include those obtained by defibrating wood pulp (e.g., softwood kraft pulp (N-BKP) such as southern pine and Douglas fir), synthetic fibers, resin fibers, non-wood pulp, etc. into a cotton-like state. When fluff pulp is used as the absorbent fiber as the base material in the absorber 16, the basis weight of the absorbent fiber is preferably 100 g / m 2 or more and 800 g / m 2 or less, more preferably 325 g / m 2 or more and 615 g / m 2 or less. Thereby, more body fluid can be absorbed without impairing the touch feeling.

[0031] The superabsorbent polymer of the absorber 16 is not particularly limited as long as it can absorb body fluid and prevent backflow. Materials formed from sodium polyacrylate-based, polyaspartate-based, (starch-acrylic acid) graft copolymer, (acrylic acid-vinyl alcohol) copolymer, (isobutylene-maleic anhydride) copolymer and its saponified product, etc. can be used. Among these, from the viewpoint of the absorption amount per unit weight, sodium polyacrylate-based is preferable.

[0032] Also, in the absorber 16, the ratio of the weight of the superabsorbent polymer to the weight of the entire absorber 16, i.e., the weight of the superabsorbent polymer / the weight of the entire absorber 16 × 100 (%) is preferably 40% or more, more preferably 40% or more and 70% or less.

[0033] In the absorber 16, the form of the absorbent fibers and the SAP may be formed by mixing SAP particles in the absorbent fibers, or may be a SAP sheet with SAP particles fixed between the absorbent fibers. Further, for the purpose of preventing leakage of the SAP particles and stabilizing the shape of the absorber 16, a carrier sheet (not shown) may be provided under the absorber 16. The base material of the carrier sheet may be any hydrophilic material, and examples thereof include hydrophilic nonwoven fabrics such as tissue, absorbent paper, and airlaid nonwoven fabric. When a plurality of carrier sheets are provided, the base materials of the plurality of carrier sheets may be the same or different.

[0034] The first individual packaging sheet 12 is an individual packaging sheet capable of individually packaging the absorbent article 11, and has a sheet body 22 for individually packaging the absorbent article 11 and a pocket (bag-like portion) 24 provided integrally with the sheet body 22.

[0035] The sheet body 22 of the first individual packaging sheet 12 can individually package the absorbent article 11 by folding it back so as to enclose the absorbent article 11 in a state where the absorbent article 11 is adhered to one surface 22a (hereinafter referred to as the "sheet one-side surface 22a"). In the present embodiment, the sheet body 22 of the first individual packaging sheet 12 is formed in a substantially rectangular shape having the same longitudinal direction and lateral direction as the absorbent article 11. The sheet one-side surface 22a of the sheet body 22 of the first individual packaging sheet 12 (hereinafter sometimes simply referred to as the "sheet one-side surface 22a of the first individual packaging sheet 12") is detachably adhered to the non-skin surface side of the back sheet 15 of the absorbent article 11 via the first adhesive layer 17. In the present embodiment, the absorbent article 11 is not adhered to the region 20 (the region 20 covered by the pocket 24 described later) at the end of one side in the longitudinal direction (the direction opposite to the direction indicated by the arrow X) of the sheet one-side surface 22a of the first individual packaging sheet 12, and is adhered to the region 21 on the other side in the longitudinal direction (the direction indicated by the arrow X) than the region 20. The length L3 in the lateral direction of the sheet body 22 of the first individual packaging sheet 12 is longer than the length L2 in the lateral direction of the absorbent article 11. The absorbent article 11 is arranged symmetrically about the center in the lateral direction of the sheet body 22 of the first individual packaging sheet 12.

[0036] The pocket 24 of the first packaging sheet 12 is provided on the sheet one-side surface 22a side of the region 20 at the longitudinal one-side end of the sheet body 22 of the first packaging sheet 12. The pocket 24 has an opening 25 that opens toward the other side in the longitudinal direction, and is formed in a bag shape with both sides in the short direction and the one side in the longitudinal direction closed. The length of the pocket 24 in the short direction is substantially the same as the length L3 of the sheet body 22 in the short direction. In the present embodiment, the pocket 24 is formed by folding back the portion continuously extending from the one-side end 26 (hereinafter referred to as "one end 26") in the longitudinal direction of the sheet body 22 of the first packaging sheet 12 to the sheet one-side surface 22a side and fixing both sides in the short direction to both sides in the short direction of the sheet body 22. That is, the pocket 24 and the sheet body 22 are composed of the same single member. The pocket 24 extends from the one end 26 in the longitudinal direction of the sheet body 22 of the first packaging sheet 12 to the other side, and the opening 25 of the pocket 24 is disposed on the one side rather than at the center in the longitudinal direction of the sheet body 22. That is, the length L4 of the pocket 24 in the longitudinal direction is shorter than half the length of the sheet body 22 of the first packaging sheet 12 in the longitudinal direction.

[0037] A second adhesive layer 23 is provided on the surface 22b (hereinafter referred to as "sheet other-side surface 22b") opposite to the sheet one-side surface 22a of the sheet body 22 of the first packaging sheet 12. That is, the first packaging sheet 12 has a sheet one-side surface 22a that is detachably adhered via a first adhesive layer 17 to the non-skin surface side of the back sheet 15 of the absorbent article 11, and a second adhesive layer 23 provided on the sheet other-side surface 22b opposite to the sheet one-side surface 22a, and is an individual packaging sheet that can individually package the absorbent article 11 by folding it back so as to enclose the absorbent article 11 in a state where the absorbent article 11 is adhered to the sheet one-side surface 22a. The second adhesive layer 23 is provided for attaching the sheet body 22 of the first packaging sheet 12 onto the top sheet 14 of the used absorbent article 11b described later. As the adhesive constituting the second adhesive layer 23, a known material can be used.

[0038] The first packaging sheet 12 (sheet body 22 and pocket 24) is any one of a colored nonwoven fabric, a resin film, paper, or a laminate of two or more of these. In the present embodiment, the first packaging sheet 12 is preferably a nonwoven fabric containing antibacterial fibers having an antibacterial activity value of 2.0 or more (hereinafter referred to as "antibacterial nonwoven fabric"), and is colored in a color different from that of the second packaging sheet 13. The basis weight of the antibacterial nonwoven fabric that is the first packaging sheet 12 is preferably in the range of 15 g / m 2 or more and 30 g / m 2 or less from the viewpoints of strength and processability. Further, it is preferable that a release agent is applied to one side surface 22a of the sheet on the skin side of the first packaging sheet 12. By applying the release agent, it becomes easy to peel the first packaging sheet 12 from the absorbent article 11, and the replacement work of the absorbent article 11 becomes easy. The release agent is preferably a silicone-based release agent or a fluorine-based release agent.

[0039] The color of the coloring of the first packaging sheet 12 can be set as appropriate. For example, as will be described later, when wrapping the used absorbent article 11b (see FIG. 7), a color can be set such that the used absorbent article 11b inside is difficult to see through. In addition to coloring, it is also possible to print a design such as a pattern on the first packaging sheet 12. Coloring of the nonwoven fabric (including the antibacterial nonwoven fabric) may be performed, for example, by using fibers colored by kneading a colorant such as a pigment or a dye to form the nonwoven fabric, or by applying a colorant to the surface of the nonwoven fabric to form a colored layer. Coloring of the resin film may be performed by melt-kneading the raw material resin and the colorant to form a film, or by forming a colored layer on the surface of the resin film by coating or the like. Coloring of the paper may be performed by immersing the paper itself in a solution or dispersion of a colorant for coloring, or by forming a colored layer on the surface of the paper by coating or the like. Note that coloring means consciously applying a color.

[0040] The second packaging sheet 13 is a sheet for protecting the second adhesive layer 23 of the first packaging sheet 12, and individually packages the absorbent article 11 together with the first packaging sheet 12. The second packaging sheet 13 is detachably adhered to the other side surface 22b of the first packaging sheet 12 via the second adhesive layer 23. That is, the second packaging sheet 13 functions as an individual packaging sheet of the absorbent article 11 by being adhered to the first packaging sheet 12. In the present embodiment, the size of the second packaging sheet 13 is formed to be substantially the same as that of the first packaging sheet 12, and the entire area thereof is adhered to the first packaging sheet 12 in a state of overlapping the first packaging sheet 12.

[0041] The second packaging sheet 13 is a non-woven fabric (including antibacterial non-woven fabric), resin film, paper, or a laminate of two or more of these, having a color different from that of the first packaging sheet 12. In a preferred embodiment, a resin film, paper, or antibacterial non-woven fabric is used for the second packaging sheet 13. The second packaging sheet 13 is preferably not colored. The basis weight of the second packaging sheet 13 is preferably in the range of 15 g / m 2 or more and 50 g / m 2 or less when it is a resin film or non-woven fabric, and preferably in the range of 30 g / m 2 or more and 70 g / m 2 or less when it is paper. Further, a release agent is preferably applied to the skin side surface (the surface side facing the first packaging sheet 12) of the second packaging sheet 13. By applying the release agent, it becomes easier to peel the second packaging sheet 13 from the first packaging sheet 12, and the replacement work of the absorbent article 11 becomes easier. The release agent is preferably a silicone-based release agent or a fluorine-based release agent.

[0042] Examples of the antibacterial nonwoven fabric used for the first packaging sheet 12 and possibly used for the second packaging sheet 13 include, for example, a nonwoven fabric containing, as a main component, antibacterial fibers with an antibacterial activity value of 2.0 or more and also containing other fibers, a nonwoven fabric made of antibacterial fibers with an antibacterial activity value of 2.0 or more, and the like. "Containing as a main component" means containing more than 50% by weight of the whole. Examples of the fibers that can be contained in addition to the antibacterial fibers include synthetic fibers made of synthetic resins such as polypropylene and polyethylene, regenerated fibers such as rayon, and natural fibers such as cotton.

[0043] The antibacterial fibers are not particularly limited as long as they are fibers having antibacterial properties, but those obtained by fibrillating synthetic fibers incorporated with an inorganic antibacterial agent are preferred. As the inorganic antibacterial agent, inorganic compounds containing antibacterial metal ions such as silver, copper, and zinc can be used without particular limitation. For example, metal compounds containing the aforementioned antibacterial metal ions, zeolites, hydrotalcites, hydroxyapatites, clay minerals, inorganic porous bodies such as alumina, silica, and bentonite can be mentioned. The inorganic antibacterial agent can be used alone or in combination of two or more. The antibacterial fibers can be produced, for example, by adding and kneading one or more inorganic antibacterial agents to a synthetic resin in a molten state and then spinning the synthetic resin. Here, examples of the synthetic resin to which the inorganic antibacterial agent is blended include polyester resins such as polyester and polyethylene terephthalate, polyolefin resins such as polyethylene and polypropylene, polyacrylamide, polyvinyl alcohol, crosslinked polyvinyl alcohol, ethylene vinyl acetate copolymer, and polyvinyl formal. The blending amount of the inorganic antibacterial agent with respect to the synthetic resin is, from the viewpoint of setting the antibacterial activity value within a predetermined range and the strength of the obtained antibacterial fibers, etc., for example, in the range of 0.005% by weight or more and 0.5% by weight or less in the total amount of 100% by weight of the inorganic antibacterial agent and the synthetic resin.

[0044] In this embodiment, in accordance with the JIS L 1902 bacterial liquid absorption method, Staphylococcus aureus and Escherichia coli are used, and an antibacterial test is carried out using a standard cloth (cotton cloth) as a control. An antibacterial fiber with an antibacterial activity value of 2.0 or more is used. Here, the antibacterial activity value is measured according to the bacterial liquid absorption method of JIS L 1902.

[0045] FIG. 4 is an external view of the absorbent article package 10 in the packaged state.

[0046] As shown in FIGS. 1 to 4, before use, the absorbent article package 10 is in a packaged state (the state shown in FIG. 4) in which the absorbent article 11 is individually packaged by the first packaging sheet 12 and the second packaging sheet 13. When in use, it can be changed to an opened state (the state shown in FIGS. 1 to 3) opened and spread from the packaged state.

[0047] When the absorbent article package 10 is put into the packaged state, first, the absorbent article 11, the first packaging sheet 12, and the second packaging sheet 13 are overlapped and adhered to each other (see FIG. 3). Next, the absorbent article 11, the first packaging sheet 12, and the second packaging sheet 13 are folded back with the skin side facing inward so as to enclose the absorbent article 11 (for example, folded into three folds in the order of the white arrows A1 and A2 shown in FIG. 3). Next, both end portions 28 in the short side direction of the first packaging sheet 12 and the second packaging sheet 13 that overlap each other (see FIG. 4) are sealed in a peelable manner. Finally, the other end portion 29 in the longitudinal direction of the first packaging sheet 12 and the second packaging sheet 13 in the extended state (see FIG. 4) is fixed to the one end portion of the folded absorbent article package 10 by a tab tape 27. In this embodiment, when putting it into the packaged state, the absorbent article 11, the first packaging sheet 12, and the second packaging sheet 13 are folded into three folds, but it is not limited thereto. For example, it may be folded into two folds or may be folded into four folds or more. Also, in this embodiment, the other end portion 29 in the longitudinal direction of the first packaging sheet 12 and the second packaging sheet 13 is fixed by the tab tape 27, but it is not limited thereto, and it may be fixed by other methods other than the tab tape 27, or may not be fixed.

[0048] When opening the absorbent article package 10 in the packaged state, pull the tab tape 27, peel the seals at both ends 28 in the short direction of the first packaging sheet 12 and the second packaging sheet 13, and spread the absorbent article 11, the first packaging sheet 12, and the second packaging sheet 13 to open it.

[0049] Next, the replacement operation of the absorbent article 11 using the absorbent article package 10 will be described with reference to FIGS. 5 to 7.

[0050] FIG. 5 is an explanatory view when replacing the absorbent article 11, showing a state where a new absorbent article 11a is overlapped with a used absorbent article 11b. FIG. 6 is an explanatory view when wrapping the used absorbent article 11b, where (a) to (c) stepwise show a state where the first packaging sheet 12 is being rolled up, and (d) shows a state where the first packaging sheet 12 has been rolled up. FIG. 7 is an explanatory view when turning over the pocket 24 of the folded first packaging sheet 12, where (a) is a cross-sectional view taken along the arrow VIIa-VIIa in FIG. 6, and (b) shows a state after turning over the pocket 24. The white arrows in FIGS. 6(a) to (c) indicate the direction of rolling up the first packaging sheet 12, and the white arrows in FIGS. 6(d) and 7(a) indicate the direction of turning over the pocket 24, respectively.

[0051] When replacing the absorbent article 11, first, open the absorbent article package 10 in the packaged state, peel the second packaging sheet 13 from the first packaging sheet 12, and expose the second adhesive layer 23 of the first packaging sheet 12. In this state, the new absorbent article 11a remains adhered to the first packaging sheet 12. The second packaging sheet 13 can be put into the turned-over pocket 24 described later and discarded.

[0052] Next, as shown in FIG. 5, with the new absorbent article 11a adhered to the sheet one side surface 22a side of the first packaging sheet 12, the second adhesive layer 23 on the sheet other side surface 22b of the first packaging sheet 12 is attached to the skin side of the used absorbent article 11b that is worn (adhered) to the underwear 40. Next, with the used absorbent article 11b attached to the first packaging sheet 12, the used absorbent article 11b, the new absorbent article 11a, and the first packaging sheet 12 are removed from the underwear 40 together.

[0053] Next, as shown in FIGS. 6(a) to 6(d), with the used absorbent article 11b overlapped on the sheet other side surface 22b of the first packaging sheet 12, the sheet body 22 of the first packaging sheet 12 and the used absorbent article 11b are rolled or folded (hereinafter simply referred to as "rolled") from the end portion on the other side in the longitudinal direction toward the one side to the sheet other side surface 22b. At this time, while rolling the sheet body 22 of the first packaging sheet 12 and the used absorbent article 11b, the new absorbent article 11a is peeled off from the first packaging sheet 12 (see FIGS. 6(b) and 6(c)). When the new absorbent article 11a is peeled off from the first packaging sheet 12 by a desired length (see FIG. 6(c)), the first adhesive layer 17 of the back sheet 15 of the new absorbent article 11a is attached to the skin side surface of the underwear 40 to attach the new absorbent article 11a to the underwear 40. Then, the sheet body 22 of the first packaging sheet 12 and the used absorbent article 11b are rolled up to before the opening 25 of the pocket 24 (see FIGS. 6(d) and 7(a)).

[0054] Next, as indicated by the white arrows in FIGS. 6(d) and 7(a), while turning the pocket 24 inside out so that the inner surface side of the pocket 24 is exposed to the outside, the rolled used absorbent article 11b and the sheet body 22 of the first packaging sheet 12 are put into the turned-out pocket 24. Finally, with the used absorbent article 11b stored in the turned-out pocket 24, the used absorbent article 11b and the first packaging sheet 12 are discarded.

[0055] In the absorbent article package 10 configured as described above, the second adhesive layer 23 is provided on the other sheet surface 22b side of the first package sheet 12. Therefore, with a new absorbent article 11a adhered to one sheet surface 22a side of the first package sheet 12, the second adhesive layer 23 of the first package sheet 12 is attached to the skin side of the used absorbent article 11b worn on the underwear 40, and the used absorbent article 11b can be removed from the underwear 40 together with the new absorbent article 11a and the first package sheet 12. In this way, the replacement operation of the absorbent article 11 can be performed with both hands without placing the new absorbent article 11a or the used absorbent article 11b on a table or temporarily attaching it to a wall or the like, so that the absorbent article 11 can be replaced hygienically and easily.

[0056] Further, since the second adhesive layer 23 of the first package sheet 12 is attached to the skin side of the used absorbent article 11b, there is also concealment, and the operation can be performed hygienically when removing the used absorbent article 11b.

[0057] In addition, since the used absorbent article 11b is wrapped with the first package sheet 12 that is colored or colored and designed, it is possible to suppress the used absorbent article 11b from being seen through, and the concealment is further improved.

[0058] Further, since the first package sheet 12 is colored in a color different from that of the second package sheet 13, it is easy to distinguish between the first package sheet 12 and the second package sheet 13. Therefore, when peeling off the second package sheet 13, there is no misoperation such as peeling off the first package sheet 12 by mistake, so that the replacement of the absorbent article 11 can be carried out smoothly according to the procedure.

[0059] In addition, since the first packaging sheet 12 is an antibacterial nonwoven fabric (a nonwoven fabric containing antibacterial fibers with an antibacterial activity value of 2.0 or more), the growth of miscellaneous bacteria on the first packaging sheet 12 is prevented. Therefore, the generation of odors associated with the growth of miscellaneous bacteria can be reduced, and the replacement operation of the absorbent article 11 can be carried out hygienically and safely. Further, in addition to the first packaging sheet 12, by using an antibacterial nonwoven fabric for the second packaging sheet 13 as necessary, the growth of miscellaneous bacteria on both the first packaging sheet 12 and the second packaging sheet 13 is prevented, so that the generation of odors associated with the growth of miscellaneous bacteria can be further reduced, and the replacement operation of the absorbent article 11 can be carried out more hygienically and safely.

[0060] Also, when rolling up the used absorbent article 11b, it is rolled up toward the other side surface 22b of the sheet from the other end portion in the longitudinal direction toward the one side. That is, since the used absorbent article 11b is rolled up toward its first adhesive layer 17 side, the spread (loosening) during rolling can be suppressed, and it is easy to roll up.

[0061] In addition, the pocket (bag-like portion) 24 of the first packaging sheet 12 is integrally provided on the sheet one side surface 22a side of the region 20 at the one end portion in the longitudinal direction of the sheet body 22 and opens toward the other side in the longitudinal direction. For this reason, after rolling up the first packaging sheet 12 and the used absorbent article 11b up to before the opening 25 of the pocket 24 (see FIGS. 6(d) and 7(a)), the pocket 24 is turned inside out, and the rolled-up used absorbent article 11b and the first packaging sheet 12 can be put into the turned-inside-out pocket 24. In this way, since the rolled-up used absorbent article 11b can be stored in the turned-inside-out pocket 24, the used absorbent article 11b can be discarded in a state with excellent concealability.

[0062] Also, since the rolled-up used absorbent article 11b can be stored in the turned-inside-out pocket 24, it is possible to prevent the rolled-up used absorbent article 11b from opening. Therefore, the concealability of the used absorbent article 11b after being discarded is also excellent.

[0063] In this way, since the used absorbent article 11b has excellent concealability, it is not necessary to wrap the used absorbent article 11b with toilet paper many times to enhance the concealability, and the amount of toilet paper used can be reduced.

[0064] Further, the pocket 24 of the first packaging sheet 12 is formed by folding back a portion that continuously extends from one end 26 in the longitudinal direction of the sheet body 22 to the side of the sheet one side surface 22a. That is, since the first packaging sheet 12 has a simple configuration in which a single sheet is folded, unlike the case where the sheet body 22 and the pocket 24 are separately prepared and fixed to each other, it can be easily manufactured with reduced man-hours.

[0065] Also, the longitudinal length L4 of the pocket 24 of the first packaging sheet 12 is shorter than half of the longitudinal length of the sheet body 22. For this reason, since the depth of the pocket 24 (the length from the opening 25 to the bottom on the one side in the longitudinal direction) can be suppressed, it is easy to turn the pocket 24 inside out.

[0066] Also, the lateral length L3 of the sheet body 22 of the first packaging sheet 12 is longer than the lateral length L2 of the absorbent article 11. For this reason, when rolling up the used absorbent article 11b together with the first packaging sheet 12, or after rolling up the used absorbent article 11b together with the first packaging sheet 12, concealability from the side surfaces (both sides in the lateral direction) of the used absorbent article 11b can be ensured.

[0067] In this way, according to the present embodiment, the absorbent article 11 can be hygienically and easily replaced, and the used absorbent article 11b can be discarded in a state with excellent concealability.

[0068] Note that in the present embodiment, the first packaging sheet 12 is made of an antibacterial nonwoven fabric, but it is not limited thereto, and it may be a colored nonwoven fabric, a resin film, paper, or a laminate of two or more of these.

[0069] In addition, in the present embodiment, the longitudinal length L4 of the pocket 24 of the first packaging sheet 12 is made shorter than half the longitudinal length of the sheet body 22. However, the present invention is not limited to this. If the pocket 24 can be turned inside out, the longitudinal length L4 of the pocket 24 may be made longer than half the longitudinal length of the sheet body 22.

[0070] In addition, in the present embodiment, the pocket (bag-like portion) 24 of the first packaging sheet 12 is formed by folding back the portion that continuously extends from one end 26 in the longitudinal direction of the sheet body 22 toward the sheet one side surface 22a. In this way, in the present embodiment, by folding a single sheet, the sheet body 22 and the pocket (bag-like portion) 24 are integrally provided. However, the present invention is not limited to this. For example, a bag-like portion formed separately from the sheet body 22 may be fixed to the sheet body 22 so that the sheet body 22 and the bag-like portion are integrally provided.

[0071] In addition, in the present embodiment, the size of the second packaging sheet 13 is made substantially the same as that of the first packaging sheet 12. However, the present invention is not limited to this. A second packaging sheet 13 smaller than the first packaging sheet 12 may be adhered to the second adhesive layer 23 of the first packaging sheet 12.

[0072] In addition, in the present embodiment, the absorbent article 11 is not adhered to the region 20 covered by the pocket 24 on the sheet one side surface 22a of the first packaging sheet 12, but is adhered to the region 21 on the other side in the longitudinal direction than the region 20. However, the present invention is not limited to this. FIG. 8 is a plan view showing a modified example of the absorbent article package 10. For example, as shown in FIG. 8, the absorbent article 11 may be adhered to the sheet one side surface 22a of the first packaging sheet 12 in a state of being inserted into the pocket 24. Alternatively, the absorbent article 11 may be adhered to the sheet one side surface 22a of the first packaging sheet 12 from above (skin surface side) of the pocket 24.

[0073] As described above, the present invention has been explained based on the above embodiments. However, the present invention is not limited to the content of the above embodiments, and can be appropriately changed without departing from the scope of the present invention. That is, other embodiments, examples, operation techniques, etc. made by those skilled in the art based on this embodiment are of course all included in the scope of the present invention.
