Prepare. Further, the absorbent article 1 includes a side sheet 41 provided outside the absorbent body 30 in the width direction W.

  The excretory opening contact region is a region that contacts the vaginal opening of the wearer in the absorbent article 1, and, for example, when the absorbent article 1 is worn on the wearer's underwear, It is an area | region arrange | positioned between opening. The center of the excretion opening contact area is the center in the longitudinal direction and the width direction of the area where the wearer's excretion opening contacts. For example, in an absorbent article having a wing portion, the center in the longitudinal direction of the wing portion is the center in the longitudinal direction of the excretory opening contact region. Moreover, in the absorbent article which does not have a wing part, the position where the length dimension of the width direction of an absorber is the shortest becomes the center of the longitudinal direction of an excretion opening | mouth contact | abutting area | region.

  The top sheet 10 is a liquid-permeable sheet that transmits liquid such as body fluid. The top sheet 10 covers at least the surface of the absorber 30. The top sheet 10 is not particularly limited as long as it is a sheet-like material having a structure that allows liquid to permeate, such as a nonwoven fabric, a woven fabric, a perforated plastic sheet, and a mesh sheet. Either natural fibers or chemical fibers can be used as the woven or non-woven material.

  Moreover, in order to suppress the liquid transfer on the top sheet 10, the surface of the top sheet 10 on the skin contact side may be roughened, or by applying air when molding the top sheet 10 made of a nonwoven fabric, You may form the unevenness of a fabric weight in a nonwoven fabric.

The packaging sheet to be measured is sandwiched between the sample scissors, the sample stage is moved so that the light receiving hole is positioned at the center of the light beam, and the lid of the optical test chamber is closed. Next, the total light transmittance is measured. The total light transmittance was measured at five locations per packaging sheet, and the average value was calculated.

(Total light transmittance measuring device)
A colorimetric color difference meter (Nippon Denshoku Industries Co., Ltd. Model NDH-300A) was used.
・ Measurement method: Conforms to JIS K7105 measurement method A ・ Measurement light source: Halogen lamp 12V4A Lifetime 2000 hours One photocell used ・ Filter: Glass filter Y
・ Measurement area Φ12mm
・ Power supply AC100V 50 / 60HZ

  Note that the packaging sheet 70 may be subjected to surface processing such as round dot embossing or satin embossing on the surface of the packaging sheet 70 for the purpose of improving the texture or the like. Examples of the material of the packaging sheet 70 include plastic films such as polyethylene, polypropylene, and polyester, various films such as nylon films, films laminated with nonwoven fabrics, and the like.

  Since the main body sheet 61 and the flap sheet 62 are bonded to the packaging sheet 70, when the absorbent article 1 is separated from the packaging sheet 70, the main body sheet 61 and the flap sheet 62 are separated from the packaging sheet 70 and the absorbent article 1. The adhesive region 52 is exposed.

  In addition, a hot-melt-type adhesive agent can be used for an adhesive and an adhesive agent, for example. In addition, the main body sheet and the flap sheet can be constituted by paper, film, or nonwoven fabric that has been subjected to a release treatment that enables peeling without reducing the adhesive strength of the adhesive. For example, a sheet obtained by coating a polyethylene terephthalate or polypropylene film with a silicone resin or a sheet obtained by laminating a polyethylene film coated with a silicone resin on paper can be used as the main body sheet 61 and the flap sheet 62.

  The absorbent article 1 and the packaging sheet 70 configured in this manner are folded at a predetermined folding position along the width direction W and the longitudinal direction L with the surface sheet 10 of the absorbent article 1 facing inward. In a state where the absorbent article 1 is folded, one end portion in the longitudinal direction L of the packaging sheet 70 is adhered to the packaging sheet 70. The edge part of the packaging sheet 70 is stuck to a part of the packaging sheet 70 by the adhesive tape 75.

  In addition, the hardness of an absorbent article etc. can be measured using the Gurley method prescribed | regulated to JIS-1096, for example. Moreover, the fabric weight and density of an absorber can be measured with the following measuring methods, for example. In the absorbent article packaged by the packaging body, the packaging body is opened, the folded absorbent article is developed, and the thickness and area of the portion where the basis weight and density are measured are measured. Subsequently, the part which measures a fabric weight and a density is cut out from an absorbent article, and the weight of the cut-out part is measured. Next, parts other than the absorber, such as the top sheet and the back sheet, are removed from the cut out part, and the weight of the absorber is measured. The basis weight is calculated based on the weight of the absorbent body and the area of the portion where the basis weight and density are measured. The density is calculated based on the basis weight and thickness.

  The thickness can be measured by the following measurement method. Specifically, after the sample absorbent article was impregnated with liquid nitrogen and frozen, it was cut with a razor and returned to room temperature, and then it was magnified 50 times using an electron microscope (for example, KEYENCE VE7800). Measure with magnification. Here, the reason why the absorbent article of the sample is frozen is to prevent the thickness from fluctuating due to compression during cutting.

  Next, a part of manufacturing method of the absorbent article 1 thus configured will be described. In addition, about the method which is not demonstrated, the existing method can be used. The manufacturing method of an absorbent article performs a surface sheet production | generation process as a 1st step. Specifically, the top sheet and the side sheet 41 are bonded by, for example, heat welding.

  Next, as a second step, an absorbent sheet forming process is performed.

  As a third step, an absorber molding process is performed. Specifically, the absorbent core 32 is formed by molding pulp as a material of the absorber with a molding drum. The manufacturing steps from the first step to the third step may be in a different order.

  In the fourth step, a joining process is performed. Specifically, a joining step of joining the topsheet and side sheet joined in the first step, the absorbent sheet 31 molded in the second step, and the absorbent core 32 molded in the third step is performed.

  In the fifth step, a pressing process is performed. Specifically, the absorber 30 and the topsheet 10 are compressed in the thickness direction to form the squeezed portion 22.

  In the sixth step, a back sheet joining step is performed. Specifically, the absorber, the top sheet, and the like that have formed the compressed parts are joined to the back sheet. After joining the back sheet, a step of applying an adhesive is provided. The absorbent article which concerns on this Embodiment can be manufactured according to said process.

  Then, based on FIG. 5, the folding method of the package 100 of an absorbent article is demonstrated. FIG. 5 is a diagram schematically showing a folding process of the package 100 of absorbent articles. The folding process of the absorbent article package 100 includes an absorbent article placing process, a first folding process, a second folding process, a cutting process, a third folding process, a fourth folding process, and a tape application. And a process.

  In the absorbent article placement step S <b> 101, the absorbent article 1, the main body sheet 61, and the flap sheet 62 are disposed on the packaging sheet 70. In addition, you may arrange | position the absorbent article 1 on the packaging sheet 70 of the dimension which wraps one absorbent article 1 separately, for example, a predetermined space | interval is provided on the packaging sheet continuous along a conveyance direction. You may comprise so that several absorbent articles may be arrange | positioned emptying.

  In 1st folding process S102, the packaging sheet 70 and the absorbent article 1 are the 1st longitudinal fold FL1 along the longitudinal direction L from the edge part area | region side including the one edge part side of the absorbent article 1 in the width direction. It is folded inward from the base point (see FIG. 1).

  In the second folding step S103, the packaging sheet 70 and the absorbent article 1 are second width folds along the longitudinal direction L from the end area side including the other end side of the absorbent article 1 in the width direction W. Folded inward from FL2 (see FIG. 1). In this state, the second width end portion 70B of the packaging sheet is joined to the non-facing surface of the packaging sheet 70 that is disposed to face the packaging sheet 70 via a hot melt adhesive. This joining area | region 90 is joining the packaging sheet 70 so that attachment or detachment is possible, and when peeling a packaging sheet, it is comprised so that it may peel (refer FIG. 6).

  Next, in the cutting step S104, the continuous body of the absorbent article 1 and the packaging sheet 70 folded back with the second longitudinal fold FL2 as a base point is cut along a cutting line along the width direction. The packaging sheet 70 and the absorbent article 1 are cut into individual product lengths.

  In the third folding step S105, the packaging sheet 70 and the absorbent article 1 are folded back with the first width fold line FW1 along the width direction W as a base point. In the third folding step S105, the conveyed absorbent article 1 and the packaging sheet 70 are folded by being pressed from above by the folding plate P.

  In the fourth folding step S106, the packaging sheet 70 and the absorbent article 1 are folded back with the second width fold line FW2 along the width direction W as a base point. In the fourth folding step S106, the conveyed absorbent article 1 and the packaging sheet 70 are folded by being pressed from the side by the folding plate P.

  In the tape sticking step S107, the front end portion of the packaging sheet in the longitudinal direction is stuck to the surface of the packaging sheet by the adhesive tape 75. The adhesive tape 75 is detachably attached to the surface of the packaging sheet with one end joined to the front end portion in the longitudinal direction of the packaging sheet and the other end folded back with the second width fold FL2 as a base point.

  According to such a folding method, the absorbent article 1 can be compactly packaged by the packaging sheet 70. Specifically, the absorbent article and the packaging sheet can be reduced to about 1/9 compared with the case where the planar area of the absorbent article and the packaging sheet is expanded, so that the absorbent article can be made compact. By reducing the size of the absorbent article 1, when storing it in a bag such as an accessory case or a pochette, it does not occupy a large space for storing the bag, and can be easily carried. Further, by packing the absorbent article 1 in a compact manner, it can be placed in the hand even when it is not folded when being carried in a toilet or the like during use, and can be kept from being seen by others.

  Furthermore, the printing area | region 73 is arrange | positioned in the outer peripheral surface of the package of an absorbent article in the state which folded the absorbent article and the packaging sheet. Since the printing region 73 is arranged on the outer peripheral surface in this way, the visibility inside the packaging sheet can be reduced compared to the configuration in which the non-printing region 74 is arranged on the outer peripheral surface. The concealability of the accommodated absorbent article can be maintained.

  From the viewpoint of ensuring the concealability of the absorbent article when the absorbent article packaging body 100 is folded, the printing area includes an area between the first width fold and the second width fold, and a first longitudinal fold FL1. And at least the region between the second longitudinal fold FL2 and the second longitudinal fold FL2. By providing the printing area in these areas, the absorbent article 1 and the packaging sheet 70 are folded based on the first longitudinal fold FL1, the second longitudinal fold FL2, the first width fold, and the second width fold. In this state, at least one surface is provided with a printing region, and the concealability of the absorbent article accommodated therein can be maintained.

  In the present embodiment, the region between the first width fold and the second width fold is a region including the first width fold and the second width fold, and the first longitudinal fold FL1 and the second longitudinal fold FL2.
