In the absorbent article packaged by the package, the package is opened, the folded absorbent article is unfolded, and the thickness and area of the portion where the basis weight and density are to be measured are measured. Next, the portion where the basis weight and the density were to be measured was cut out from the absorbent article, and the weight of the cut portion was measured. Next, portions other than the absorber such as the surface sheet and the back sheet are removed from the cut portions, and the weight of the absorber is measured. The basis weight was calculated from the weight of the absorber and the area of the portion where the basis weight and density were to be measured. The density is calculated from the basis weight and thickness.

Further, the thickness can be measured by the following measurement method. Specifically, the absorbent article of the sample is impregnated with liquid nitrogen to be frozen, and then cut with a razor, returned to normal temperature, and then measured at an magnification of 50 times using an electron microscope (for example, Keyence VE7800). Here, the reason why the absorbent article of the sample is frozen is to prevent the thickness from changing due to compression at the time of cutting.

Next, a part of the manufacturing method of the absorbent article 1 configured in this manner will be described. Further, a known method can be used for the method not described. In the method of producing an absorbent article, the surface sheet forming step is performed in the first step. Specifically, the surface sheet is followed by the side sheet 41 by, for example, heat fusion.

Next, the second step is to perform an absorption sheet forming step. Specifically, the absorbent sheet is formed, and the essential oil is applied to form the aromatic region 80.

The third step is to perform an absorber forming step. Specifically, the absorbent core 32 is formed by molding a pulp forming an absorbent material by a molding cylinder. Further, the processes from the first step to the third step may be in different orders.

The fourth step is to perform the bonding step. Specifically, a bonding step of joining the surface sheet and the 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.

The fifth step is to carry out the pressing step. Specifically, the absorber 30 and the surface sheet 10 are compressed in the thickness direction to form the press portion 22.

The sixth step is to perform a back sheet bonding step. Specifically, the absorber, the surface sheet, and the like in which the press portion is formed are joined to the back sheet. There is a step of applying an adhesive after bonding the back sheets. By the above steps, the absorbent article of the present embodiment can be produced.

Next, a folding method of the package 100 of the absorbent article will be described based on FIGS. 4 and 5. Fig. 4 is a schematic view showing a folding step of the package 100 of the absorbent article. Fig. 5 is a schematic perspective view showing a folded state of the package of the absorbent article. 6 is a cross-sectional view taken along line B-B of FIG. 5. The folding step of the package 100 for an absorbent article includes an absorbent article placing step, a first folding step, a second folding step, a cutting step, a third folding step, a fourth folding step, and a tape bonding step.

In the package 100 of the absorbent article according to the first embodiment, the first direction is the longitudinal direction L, and the second direction is the width direction W. Therefore, the first long side crease and the second long side crease along the longitudinal direction are folded as a base point, and then the first wide side crease and the second wide side crease along the width direction are used as a base point. The way of folding is made up.

In the absorbent article placing step S101, the absorbent article 1, the main body sheet 61, and the wing-shaped sheet 62 are placed on the packaging sheet 70. In addition, it may be disposed on the packaging sheet 70 of an absorbent article 1 individually packaged. The absorbent article 1 can be configured, for example, by arranging a plurality of absorbent articles at predetermined intervals on a continuous packaging sheet along the conveying direction.

In the first folding step S102, the packaging sheet 70 and the absorbent article 1 include the end portion region side on one side of the absorbent article 1 in the width direction, and the first long side crease FL1 along the longitudinal direction L. (Refer to Fig. 1) The base point is folded back toward the inside. Fig. 5(a) is a package of an absorbent article in a state of being folded by the first folding step.

In the second folding step S103, the packaging sheet 70 and the absorbent article 1 include the end portion side of the other end side of the absorbent article 1 from the width direction W, and the second long side in the longitudinal direction L is folded. The mark FL2 (refer to Fig. 1) is a base point which is folded inward toward the inside. Fig. 5(b) is a package of an absorbent article in a state of being folded by the second folding step.

Next, in the cutting step S104, the continuous body of the absorbent article 1 and the packaging sheet 70 which is folded back based on the second long side crease FL2 is cut along the cutting line in the width direction. The packaging sheet 70 and the absorbent article 1 are cut to form individual article lengths.

Further, in the state shown in Fig. 5(b), the outer end portion 70b in the width direction of the packaging sheet is joined to the non-opposing surface of the packaging sheet 70 which is disposed to face each other via a hot-melt type adhesive. This joint region is a first joint region 91 to be described later. Moreover, the longitudinal side outer end portions 70c and 70d of the packaging sheet 70 are joined to each other by the heat fusion to form the oppositely disposed packaging sheets 70. This joint region is a second joint region 92 to be described later.

In the third folding step S105, the packaging sheet 70 and the absorbent article 1 are reversed with respect to the first wide-edge crease FW1 along the width direction W. First The folding step S105 is such that the conveyed absorbent article 1 and the packaging sheet 70 are folded by pressing the folding sheet P from above.

In the fourth folding step S106, the packaging sheet 70 and the absorbent article 1 are folded at the basis of the second wide-edge crease FW2 along the width direction W.

In the tape sticking step S107, the front end portion of the packaging sheet in the longitudinal direction is adhered to the surface of the packaging sheet by the adhesive tape 75. Fig. 5(c) is a package of an absorbent article in a state in which the adhesive tape 75 is adhered. The adhesive tape 75 is a front end portion joined to the longitudinal direction of the packaging sheet at one end, and the other end is releasably adhered to the surface of the packaging sheet in a state of being folded back with the second wide-side crease FW2 as a base point.

According to this folding method, the absorbent article 1 can be densely packed by the packaging sheet 70. Specifically, it can be formed by about 1/9 compared with the case where the plane area of the absorbent article and the packaging sheet is increased, so that the absorbent article can be reduced. When the absorbent article 1 is downsized, it is stored in a bag such as a small bag or a tote bag, and the storage space of the bag is not taken up, and it can be easily carried. Moreover, by densely packing the absorbent article 1, when it is carried to the toilet when it is used, it can be placed in the hand even in a state of not folding back, and it is held in the hand without being seen.

In the package 100 of the absorbent article, the outer end portions 70a and 70b in the width direction of the packaging sheet 70 are in the absorbent article 1 in a state in which the first long side crease FL1 and the second long side crease FL2 are folded as a base point. The thickness direction T is laminated. In addition, the package body 100 of the absorbent article is folded in a state in which the first wide crease and the second wide crease are folded, and the outer side end portions 70c and 70d of the packaging sheet 70 are laminated in the thickness direction.

In the state in which the first long side crease FL1 and the second long side crease FL2 are folded, the widthwise outer end portions 70a and 70b of the packaging sheet 70 are laminated to each other, so that the outer side end portion 70a of the packaging sheet 70 in the width direction can be used. And 70b covers the periphery of the absorbent article 1. Therefore, it is easy to maintain the absorbent article accommodated inside, and it is possible to suppress the leakage of the aroma to the outside of the package of the absorbent article so that the fragrance moves to the surroundings, or the efficacy of the aroma is lowered.

In the outer side end portion 70b of the second long side crease side of the outer side end portion of the packaging sheet 70 in the width direction, a package for arranging the second long side crease as a base point is provided. The non-opposing surface 72 of the sheet 70 and the first joining region 91 joined to the widthwise outer end portion 70b on the second long side fold side (see FIG. 5). The first bonding region 91 is, for example, a region to which a hot-melt type adhesive is applied.

By joining the outer end portion 70b of the packaging sheet 70 in the width direction by the first joining region 91, the sealing property can be further improved, and the fragrance of the aromatic region 80 can be sealed inside.

Further, the first bonding region 91 may be bonded by other bonding methods such as heat welding or ultrasonic welding. Further, the first joining region 91 may not necessarily be provided.

The second joining region 92 joined to each other. The second bonding region 92 is a region that is followed by thermal fusion bonding, for example.

When the long-side outer end portions 70c and 70d of the packaging sheet 70 are unsealed, and the wide-edge crease is reversed as a base point, the fragrant components may flow out from the long-side outer end portions 70c and 70d of the packaging sheet. However, by joining the longitudinal side outer end portions 70c and 70d of the packaging sheet 70 by the second joining region 92, the sealing property can be further improved, and the fragrance of the aromatic region 80 can be sealed inside.

Further, the second bonding region 92 may be bonded by another bonding method such as bonding using an adhesive. Further, the second joining region 92 may not necessarily be provided, and may be, for example, one of the long-side outer end portions 70c and 70d of the packaging sheet. Preferably, it is preferable that the second outer side is provided at the outer side end portion (the outer side end portion 70d in the longitudinal direction of the front side) which is folded in the longitudinal direction outer end portions 70c and 70d of the packaging sheet. Area 92.

Further, the aromatic region 80 is provided between the first long side crease FL1 and the second long side crease FL2. Therefore, the packaging sheet 70 and the absorbent article 1 can be folded in the width direction from the first long side crease FL1 in a state in which the first long side crease FL1 and the second long side crease FL2 are folded as a base point. The sheet 70 and the absorbent article 1 and the packaging sheet 70 and the absorbent article 1 on the outer side in the width direction of the second long-edge crease FL2 cover the aromatic region 80.

Further, the first long side crease FL1 and the second long side crease FL2 are disposed outside the absorbent core 32 of the absorber 30 in the width direction, and do not overlap the absorbent core 32. For example, when the first long side crease FL1 and the second long side crease FL2 are disposed so as to overlap the absorbent core 32, the first long side crease FL1 and the second side are provided. The portion formed by the long side crease FL2 is thick, and the gap is easily formed in a state in which the first long side crease FL1 and the second long side crease FL2 are folded as a base point. However, since the first long side crease FL1 and the second long side crease FL2 are formed in a thin portion of the absorbent article, the gap at the time of folding can be reduced, and the sealing property can be improved.

Further, the aromatic region 80 of the present embodiment is disposed between the first long side crease FL1 and the second long side crease FL2 in the width direction W, and the first wide crease FW1 and the second width in the longitudinal direction L. Between the creases FW2, the present invention is not limited to this configuration, and may be folded between the first long side crease FL1 and the second long side crease FL2 in the width direction W, and the first wide side is folded in the longitudinal direction L. The mark FW1 and the second wide-side crease FW2 extend outward in the longitudinal direction.

Further, the aromatic region 80 is formed by covering the first long side crease FL1 and the second long side crease FL2 with the wing-shaped sheet 62 as a base point. Further, a main sheet 61 is disposed on the back sheet side of the fragrance region 80, and the fragrance region 80 is sandwiched by the main sheet 61 and the wing sheet 62 in the thickness direction T.

In general, the main sheet 61 and the airfoil sheet 62, which are release sheets, are subjected to a release treatment using an anthrone. The anthrone has high airtightness and can inhibit the diffusion of the flavor component. Therefore, in a state in which the first long side crease FL1 and the second long side crease FL2 are folded as a base point, the main sheet 61 and the wing sheet 62 are sandwiched by the aroma region 80 and covered, whereby the composition of the aromatic region can be effectively suppressed. Deterioration.

Further, it is preferable that the first long side crease FL1 and the second long side crease FL2 are disposed so as not to overlap the main body sheet 61 and the wing sheet 62. From suppressing aroma From the viewpoint of deterioration of the composition, it is preferable that the area ratio of the release sheet is higher than that of the packaging sheet 70. However, the rigidity of the release sheet is preferably higher than that of the packaging sheet 70 or the like, and the first long side crease FL1 and the second long side crease FL2 are not formed. If a crease is formed in a member having a high rigidity, the packaging sheet 70 is not easily adhered in a state in which the crease is folded at the base point. Once the packaging sheets 70 are not in close contact, a gap is easily formed in the packages so that the fragrance flows out.

Therefore, in order to reduce the gap between the folded packaging sheet 70 and the state of the absorbent article 1, the thickness of the portion where the first long side crease FL1 and the second long side crease FL2 are formed is preferably thin, specifically, preferably 1 mm. the following.

Further, the side flap portion 43 has a first wing portion 43A and a second wing portion 43B which are disposed on the right and left sides of the absorber. The packaging sheet 70, the first wing portion 43A, and the second wing portion 43B are folded in a state in which the first long side crease FL1 and the second long side crease FL2 are folded, and the first wing portion 43A and the packaging sheet 70 are formed. The second wing portion 43B and the packaging sheet 70 are laminated in this order.

According to the above configuration, the wing portions and the packaging sheets can be alternately laminated to cover the fragrance region 80. For example, when the aroma region is covered only by the packaging sheet, the difference in the concentration of the aroma components on the inner side (the aroma region side) and the outer side (the outer side of the packaging sheet) of the packaging sheet is large, and the aroma component is likely to be easily dispersed. However, by arranging the non-woven sheets of the wings between the packaging sheets, it is also possible to alleviate the concentration gradient, so that the aroma components are not easily dispersed, assuming that the aroma components are dispersed to the outside.
