The adhesive region includes a main body adhesive region 51 (see FIG. 3) provided on the non-skin contact side surface of the absorbent main body 1A and a flap adhesive region 52 provided on the non-skin contact side surface of the flap portion 1B. (See FIG. 3). In addition, although the flap adhesion area | region 52 which concerns on this Embodiment is provided only in the wing flap part 43, you may be provided in the hip flap part 44. FIG.

In the state before use, the main body adhesive region 51 is covered with a main body sheet 61 as a release sheet, and the flap adhesive region 52 is covered with a flap sheet 62 as a release sheet. The main body sheet 61 and the flap sheet 62 prevent the adhesive from deteriorating before use.

The main body sheet 61 is disposed between the main body adhesive region 51 and the packaging sheet 70. The surface of the main body sheet 61 on the main body adhesive region 51 side is subjected to a mold release process and is configured to be separated from the main body adhesive region 51. The surface of the flap sheet 62 on the side of the flap adhesive region 52 is subjected to a mold release process, and is configured to be separated from the flap adhesive region 52.

The main body sheet 61 and the flap sheet 62 are each bonded to the packaging sheet 70 via an adhesive. The main body sheet and the flap sheet side surface of the packaging sheet 70 have a main body bonding area 65 to which an adhesive for bonding the main body sheet 61 is applied, and a flap bonding area 66 to which an adhesive for bonding the flap sheet 62 is applied. Are provided in plural.

The main body sheet 61 is disposed on the inner side in the width direction with respect to a first longitudinal fold FL1 and a second longitudinal fold FL2 described later, and functions as an inner release sheet. The flap sheet 62 includes the first longitudinal fold FL1 and the first longitudinal fold FL1. It arrange | positions in the width direction outer side rather than 2nd longitudinal fold FL2, and functions as an outer side release sheet.

The main body adhesion region 65 has a streak shape extending in the longitudinal direction, has a width shorter than the main body adhesion region 51, and is arranged side by side more than the main body adhesion region 51. In addition, the flap adhesion region 66 has a shorter width than the flap adhesion region 52 and is arranged side by side more than the flap adhesion region 52.

The packaging sheet 70 wraps the absorbent article 1 individually. The packaging sheet 70 has a facing surface 71 that faces the absorbent article 1 on the back sheet 20 side of the absorbent article 1 and a non-facing surface 72 that is positioned outside in a state in which the absorbent article 1 is accommodated.

The widthwise ends of the packaging sheet are a first width end 70A disposed on the first longitudinal fold side and a second width end 70B disposed on the second longitudinal fold side, both of which are long Arranged along the direction. Moreover, the edge part of the longitudinal direction of a packaging sheet is the front-end part 70C arrange | positioned at the front side, and the rear-end part 70D arrange | positioned at the rear side, and all are arrange | positioned along the width direction.

Note that the packaging sheet 70 may be subjected to a surface treatment 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, for the pressure-sensitive adhesive and the adhesive, for example, a hot melt adhesive can be used. In addition, the main body sheet and the flap sheet can be made of paper, film, or nonwoven fabric that has been subjected to a treatment release treatment that allows the main sheet and the flap sheet to be peeled 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 inside. 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 measuring 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 the manufacturing method of the absorbent article 1 configured as described above 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 the 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 process 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.

Next, a method for folding the absorbent article package 100 will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram schematically showing a folding process of the absorbent article packaging body 100. FIG. 5 is a perspective view schematically showing a folded state of the package of the absorbent article. 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 S101, 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). Fig.5 (a) has shown the package of the absorbent article of the state folded by the 1st folding process.

In the second folding step S103, the packaging sheet 70 and the absorbent article 1 are second longitudinal folds along the longitudinal direction L from the end region side including the other end side of the absorbent article 1 in the width direction W. Folded inward from FL2 (see FIG. 1). FIG.5 (b) has shown the package of the absorbent article of the state folded by the 2nd folding process.

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.

Further, in the state shown in FIG. 5 (b), the front end portion 70C and the rear end portion 70D of the packaging sheet 70 are joined to each other by facing the packaging sheets 70 arranged facing each other. This joining region 90 is shown by hatching in FIG. The joining area | region 90 is provided in the width direction whole region of the rear-end part 70D of the packaging sheet 70, and the width direction center area of the front-end part of a packaging sheet.

In the third folding step S105, the packaging sheet 70 and the absorbent article 1 are folded back based on the first width fold FW1 along the width direction W. Specifically, the rear end portion 70D of the packaging sheet and the rear end portion 1D of the absorbent article are folded forward from the first width fold line FW1 along the width direction. In this state, the rear end portion 70D of the packaging sheet extends forward from the second width fold FW2. 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. Specifically, the front end portion 70C of the packaging sheet, the front end portion 1C of the absorbent article, and the rear end portion 70D of the packaging sheet are folded backward from the second width fold line FW2. 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.

At this time, the joining region 90 of the front end portion 70C of the packaging sheet 70 is not provided in the entire width direction, but is provided only in the center in the width direction. A non-joining region 91 where the sheets are not joined is provided.

For example, if the joining region 90 is provided in the entire width direction of the front end portion 70C and the entire width direction of the rear end portion 70D of the packaging sheet in a state where the packaging sheet is folded in the fourth folding step S106, the fourth folding process is performed. When folded in step S106, the air inside the packaging sheet 70 may be pressed and the packaging sheet may be torn. Even if the packaging sheet is not torn, the air inside the packaging sheet is difficult to escape and the package 100 of the absorbent article may not be compact.

However, since the non-joining area | region 91 where the packaging sheets are not joined is provided in the width direction both ends of the front-end part 70C of the packaging sheet 70, when a packaging sheet is folded in 4th folding process S106, The air inside the packaging sheet can be easily removed, the packaging sheet can be prevented from being broken when folded, and the package of the absorbent article can be made compact.

In addition, although the non-joining area | region 91 is provided in the front-end part 70C of the packaging sheet 70, the package body of the absorbent article of this Embodiment is not restricted to this structure. For example, the non-joining region 91 may be provided in the front end portion 70C of the packaging sheet 70, or the non-joining region 91 may be provided in both the front end portion 70C and the rear end portion 70D of the packaging sheet 70.

In the tape affixing step S107, the front end portion of the packaging sheet in the longitudinal direction is affixed to the surface of the packaging sheet by the adhesive tape 75. FIG.5 (c) has shown the package body of the absorbent article in the state in which the adhesive tape 75 was stuck. The adhesive tape 75 is detachably attached to the surface of the packaging sheet with one end joined to the front end in the longitudinal direction of the packaging sheet and the other end folded back with the second width fold FW2 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.

Next, the opening mode of the package 100 of the absorbent article folded in this way will be described in detail with reference to FIG. FIG. 6 is a view schematically showing a state where the absorbent article 1 individually packaged by the packaging sheet 70 is opened. When opening the package 100 of the absorbent article, for example, the other adhesive tape 75 is held in a state where the longitudinal end of the packaging sheet 70 and the longitudinal end of the absorbent article 1 are suppressed with one hand. The adhesive tape 75 is pulled in a direction away from the packaging sheet 70 held and held by one hand.

By pulling the adhesive tape 75, the front end portion 70C of the packaging sheet 70 to which the adhesive tape 75 is attached is pulled together with the adhesive tape 75, and developed from the second width fold FW2. In the state shown in FIG. 5D, the rear end portion 70D of the packaging sheet is folded back toward the rear from the second width fold line FW2 together with the front end portion 1C of the absorbent article and the front end portion 1C of the packaging sheet. Therefore, in the unfolded state shown in FIG. 6, the rear end portion 70D of the packaging sheet is formed with a mountain fold line from the top sheet side to the back sheet side, and the rear end portion 70D of the packaging sheet rises.

In the opening operation of the absorbent article packaging body 100, the rear end portion 70D of the packaging sheet 70 is then gripped and developed with the first width fold FW1 as a base point. At this time, since the rear end portion 70D of the packaging sheet rises, the rear end portion 70D of the packaging sheet can be easily grasped, and the operability at the time of mounting can be improved.

FIG. 7 is a diagram schematically showing a fold line in a developed state of the absorbent article package. In FIG. 7, a mountain fold MF that is a fold from the top sheet side to the back sheet side is indicated by a one-dot chain line, and a valley fold VF that is a fold from the back sheet side to the top sheet side is indicated by a two-dot chain line.

As shown in FIG. 7, between the first longitudinal fold FL1 and the second longitudinal fold FL2, the front end portion 1C of the absorbent article faces from the back sheet side to the top sheet side by the second width fold FW2 in the unfolded state. Is folded. Further, between the first longitudinal crease FL1 and the second longitudinal crease FL2, the central portion between the front end portion and the rear end portion of the absorbent article is also surfaced from the back sheet side by the first width fold FW1 in the unfolded state. It is folded toward the seat side.

Since the front end portion and the central portion of the absorbent article are valley-folded, the front side and the rear side are more likely to rise to the topsheet side than the central portion, and the absorbent article is disposed along the back side from the wearer's stomach side. It becomes easy.

Further, the fold formed by the first width fold is a valley fold between the first longitudinal fold FL1 and the second longitudinal fold FL2, and is wider than the first longitudinal fold in the width direction and wider than the second longitudinal fold. It is a mountain crease on the outside in the direction.

As described above, the package of the absorbent article can be arranged along the body in the front-rear direction by being a valley fold between the first longitudinal fold FL1 and the second longitudinal fold FL2. However, if the valley fold extends to the outside in the width direction between the first longitudinal fold FL1 and the second longitudinal fold FL2, a gap due to the valley crease is formed to the width direction end of the absorbent article, and on the body instead There exists a possibility that an absorbent article may not be arrange | positioned along. However, since it is a mountain fold on the outer side in the width direction than the first longitudinal fold line and on the outer side in the width direction than the second longitudinal fold line, the flap portion can be deformed so as to face the body side, and the gap can be filled.

On the garment contact surface of the wing flap portion, there are provided a flap adhesion region 66 to which an adhesive for sticking an absorbent article to the garment and a non-adhesion region 67 to which no adhesive is attached. Yes. A non-adhesive region 67 is provided on the clothing contact surfaces of the wing flap portion and the hip flap portion that are folded back from the top sheet side to the back sheet side by the first width fold line FW1 (see FIG. 2). That is, the first width fold line is not disposed so as to overlap the flap adhesion region 66.

For example, when the first width fold line is disposed so as to overlap the flap adhesion region 66, when the absorbent article 1 is mounted on the underwear, the portion where the first width fold line is formed is put on the underwear by the adhesive. There is a possibility that the effect of creases cannot be exhibited. However, since the said part is not adhere | attached on underwear by the adhesion part, it can be easy to exhibit the effect of the crease | fold by the 1st width crease | fold FW1.

Moreover, as shown in FIG.5 and FIG.6, the 2nd width | variety crease | fold formed in the rear-end part of the packaging sheet 70 is located in the innermost side in the thickness direction in the state which folded the package 100 of the absorbent article. . Therefore, the crease in the package of the absorbent article is strong because the second width fold formed at the rear end of the packaging sheet 70 is located at the innermost side in the thickness direction, and the other folds are formed after the packaging sheet 70. It is weaker because it is located on the outer side in the thickness direction than the second width fold formed at the end. Therefore, the crease remaining in the absorbent article itself can be reduced.

(Second Embodiment)
Next, the absorbent article packaging body 101 according to the second embodiment will be described with reference to FIG. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

In the absorbent article packaging body 101 according to the second embodiment, the rear end portion 70D of the packaging sheet 70 and the rear end portion 1D of the absorbent article 1 are formed of the front end portion 70C of the packaging sheet 70 and the absorbent article 1. Along with the front end portion 1C, the second width fold line FW2 is folded at the base point.

Therefore, the rear end portion 70D of the packaging sheet 70 and the rear end portion 1D of the absorbent article 1 are folded back to the back sheet side by the mountain folds in a state where the second width fold FW2 is developed as a base point.

Generally, when wearing an absorbent article, the absorbent article is attached to the crotch portion of the undergarment, and then the undergarment is pulled up. At this time, when trying to wear the absorbent article with the rear end portion 70D of the absorbent article 1 standing up, the rear end portion of the absorbent article may be caught when the underwear is pulled up, and the absorbent article may be bent. There is.

In particular, the rear end portion 1D of the absorbent article is easily entangled when worn because the wearer's buttocks swell and is difficult to see when worn. Once the rear end of the absorbent article is caught, the adhesive for attaching the absorbent article to the underwear sticks to the body or other parts of the absorbent article, or the absorbent article bends and absorbs. There is a possibility that the article cannot be properly mounted.

However, since the rear end portion 1D of the absorbent article is folded back to the underwear side, it is possible to prevent the rear end portion of the absorbent article from being caught when the absorbent article is attached after being attached to the underwear.

Moreover, in the unfolded state shown in FIG. 8, the center in the width direction of the rear end portion of the absorbent article is folded from the top sheet side toward the back sheet side by the second width fold line FW2, and the rear end portion of the absorbent article is Both ends in the width direction are folded back from the back sheet side to the top sheet side by the second width fold line FW2.

Since the center in the width direction of the rear end of the absorbent article is a mountain fold and both ends in the width direction are valley folds, the rear end of the absorbent article rises toward the wearer around the center in the width direction. It becomes easy to arrange | position the rear-end part of articles | goods along the roundness of a wearer's buttocks.

The first width fold line FW1 is formed in an inclined region between the maximum width position 43M having the longest width direction length of the wing flap portion 43 and the longitudinal end portion 43L of the wing flap portion in the longitudinal direction. The wing flap portion on the outer side in the width direction than the first longitudinal fold FL1 and the second longitudinal fold FL2 is folded back from the top sheet side to the back sheet side by the first width fold FW1.

The wing flap portion has a length in the width direction that gradually decreases outward in the longitudinal direction from the maximum width position having the longest length in the width direction, and has an inclined region that is inclined with respect to the width direction and the longitudinal direction. . Further, the wing flap portion is thinner than the region where the absorber is disposed, and it is difficult to keep a flat state with respect to the underwear. Moreover, the flap adhesion area | region 66 is provided in the back surface of the wing flap part, and when the wing flap part is turned back to the non-contact surface side of underwear, the malfunction that adhesives adhere may arise.

However, by providing the first width fold FW1 in the inclined region, a mountain fold is formed in the wing flap portion by the first width fold FW1, and a valley fold is formed between the mountain folds. Since the mountain folds and the valley folds are alternately formed in the wing flaps, the wing flaps can easily maintain a horizontal state. Therefore, the action of the first width fold line FW1 makes it easy to keep the wing flap portion horizontal, and it is possible to suppress problems that the both end portions of the wing flap portion are involved and the adhesives stick to each other.

The body contact area 65 to which a pressure-sensitive adhesive for attaching the absorbent article to the clothes is provided on the clothes contact surface of the back sheet. The main body adhesion region 65 is disposed in front of the second width fold line FW2 located on the rear side. If there is an adhesive at the part folded back by the second width fold FW2, there is a possibility that the adhesive will stick to the back sheet before being attached to the underwear. However, since the adhesive is not attached to the portion folded back on the back sheet side, the above-mentioned problems can be solved.
