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 flap, the longitudinal center of the wing flap is the longitudinal center of the excretory opening contact region. Moreover, in the absorbent article which does not have a wing flap 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.

The back sheet 20 is preferably made of a material having flexibility that does not cause a sense of incongruity when worn. The back sheet 20 of the present embodiment is constituted by a liquid-impermeable polyethylene film.

The absorbent body 30 includes an absorbent sheet 31 made of a tissue or a non-woven fabric, and an absorbent core 32 disposed on the skin contact side with respect to the absorbent sheet 31 and laminated with pulp. The absorbent core 32 includes a lower absorbent core 32A that is in contact with the skin contact side surface of the absorbent sheet 31, and an upper absorbent core 32B that is in contact with the skin contact side surface of the lower absorbent core 32A. Have.

The absorbent sheet can be formed of tissue or non-woven fabric. As a nonwoven fabric which comprises an absorption sheet, it is a nonwoven fabric which consists of thermoplastic fibers, Comprising: The nonwoven fabric which performed the hydrophilic process and the nonwoven fabric which consists of hydrophilic fibers can be used. In addition, an airlaid sheet obtained by forming hydrophilic fibers or powder into a sheet by an airlaid method can be used as the nonwoven fabric constituting the absorbent sheet.

The absorbent core 32 is smaller than the absorbent sheet 31 in the longitudinal direction L and the width direction W. The upper absorbent core 32B is smaller in the longitudinal direction L and the width direction W than the lower absorbent core 32A. The upper absorbent core 32B is configured to have a higher basis weight of the absorbent material than the lower absorbent core 32A, and is disposed in the excretory opening contact region. The upper absorbent core 32B is provided in a region surrounded by the compressed portion 22 in which the topsheet 10 and the absorbent body 30 are compressed in the thickness direction in the plan view shown in FIG.

The upper absorbent core 32B and the lower absorbent core 32A may be configured separately or may be integrated. The absorbent core 32 according to the present embodiment is formed by integrating an upper absorbent core 32B and a lower absorbent core 32A. When the absorbent sheet 31 and the absorbent core 32 are configured separately, they may be bonded together with an adhesive such as a hot melt adhesive.

It is preferable that the top sheet 10, the absorber 30, and the back sheet 20 are bonded together to prevent interlayer separation. These joints can be used alone or in combination with embossing, ultrasonic waves, hot melt adhesives, and the like. Further, the absorber may be embossed in order to prevent the absorber from being deformed or twisted when worn, or to adjust the thickness of the absorber.

The side sheet 41 is disposed on both sides of the top sheet 10. The side sheet 41 can be selected from the same material as the top sheet 10. However, in order to prevent menstrual blood from flowing over the side sheet 41 to the outside of the absorbent article 1, it is preferable to have hydrophobicity or water repellency. Specific examples include spunbond nonwoven fabrics and SMS nonwoven fabrics. In particular, an air-through nonwoven fabric is preferable in order to reduce irritation to the skin due to rubbing.

The side sheet 41 covers a part of the side edge of the absorber 30 and the flap portion 1B. The inner end portion 41E in the width direction of the side seat 41 is disposed adjacent to the first longitudinal fold FL1 and the second longitudinal fold FL2 outside the first longitudinal fold FL1 and the second longitudinal fold FL2, which will be described later, on the outer side in the width direction. ing.

In the absorbent article 1, the peripheral edges of the top sheet 10, the side sheet 41, and the back sheet 20 are joined, and the absorbent body 30 is enclosed. As a method for joining the top sheet 10 and the back sheet 20, any one or a combination of heat embossing, ultrasonic waves, or hot melt adhesive can be used.

A plurality of adhesive regions coated with an adhesive are provided on the surface of the back sheet 20 that comes into contact with the undergarment. The adhesive region includes a main body adhesive region 51 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. In addition, although the flap adhesion area | region 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 the main body sheet 61, and the flap adhesive region 52 is covered with the flap sheet 62. 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 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.

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.

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 hot melt adhesive constituting the main body adhesive region 65 and the flap adhesive region 66 is applied to the main body sheet 61 and the flap sheet 62, and then the absorbent article is placed on the packaging sheet 70. 1. A main body sheet 61 and a flap sheet 62 are disposed. 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.

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. In the third folding step S105, the conveyed absorbent article 1 and the packaging sheet 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 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.

Further, the first longitudinal fold FL1 and the second longitudinal fold FL2 in a state where the package 100 of the absorbent article folded in this manner is opened are outside in the width direction of the absorbent core 32 of the absorbent body 30, and are side sheets. It is located inside 41 in the width direction. As shown in FIG. 3, the first longitudinal crease FL1 and the second longitudinal crease FL2 are formed in a region where the top sheet 10 and the back sheet 20 overlap. The first longitudinal fold FL1 and the second longitudinal fold FL2 do not overlap the absorbent core 32 and the side sheet 41 in the thickness direction T.

Therefore, the crease caused by the first longitudinal fold FL1 and the second longitudinal fold FL2 is formed only on the top sheet 10, the back sheet 20, and the absorbent sheet 31. In general, the absorbent sheet 31 is thinner than the absorbent core 32, and when the crease is formed, the absorbent sheet itself is less likely to be recessed. On the other hand, the absorbent core 32 is thicker than the absorbent sheet 31, and when a crease is formed, an absorbent material such as pulp constituting the absorbent core moves around the crease, so that a dent is easily formed. Therefore, the crease caused by the first longitudinal crease FL1 and the second longitudinal crease FL2 is not formed in the absorbent core 32, and thus hardly remains.

Therefore, it is difficult for folds in the longitudinal direction to remain, and when the absorbent article 1 is attached to the underwear, the absorbent article 1 can be prevented from floating from the underwear due to the fold. The wearer can easily place the absorbent article along the inner surface of the underwear, or the wing flap part can be easily folded and placed on the non-skin contact surface side of the underwear, improving wearability Can be made.

Since the longitudinal crease is disposed between the main body sheet and the flap sheet, the longitudinal crease does not overlap both the main body sheet and the flap sheet, and the absorbent article and the packaging sheet are formed with the longitudinal crease. The The portion where the absorbent article and the packaging sheet are overlapped is lower in rigidity than the portion where the main body sheet or the flap sheet is also overlapped, and the absorbent article, the packaging sheet and the main body sheet or the flap sheet are stacked three layers. Compared with the configuration in which the longitudinal folds are formed in the folds, the creases are less likely to remain.

It should be noted that the rigidity in this specification means the degree to which an object resists deformation when an external force is applied to the object to cause deformation. For example, the higher the rigidity, the greater the resistance to deformation and the stronger the crease when folded.

For example, if the folds are formed in the main body sheet 61 and the flap sheet 62, it becomes difficult to fold compared to the configuration in which the folds are formed in the packaging sheet, and the main body sheet and the flap sheet are not bent along the folds. There is a possibility that the crease cannot be formed at the position. Furthermore, even when a crease is formed in the packaging sheet and the flap sheet, the corner of the crease is hard, and the packaging sheet may be broken by the corner of the crease of the main body sheet or the like. However, since the fold is not formed in the main body sheet 61 and the flap sheet 62, the occurrence of the above-described problems can be suppressed.

Further, on the inner side in the width direction and the outer side in the width direction with the longitudinal fold line interposed therebetween, a portion where the absorbent article, the packaging sheet and the main body sheet or the flap sheet are overlapped (a portion having high rigidity) is disposed. Since the highly rigid parts are arranged on both sides in the width direction across the longitudinal fold, it is possible to apply a relatively strong force to keep the absorbent main body and the flap part flat during deployment. , It is possible to suppress problems caused by creases.

Further, a side sheet 41 is provided on the outer side in the width direction of the first longitudinal fold FL1 and the second longitudinal fold FL2, and the rigidity on the outer side in the width direction is higher than that of the first longitudinal fold FL1 and the second longitudinal fold FL2. Has been. Therefore, the packaging body of the absorbent article is caused by the difference in rigidity between the portion where the first longitudinal fold FL1 and the second longitudinal fold FL2 are formed and the portion outside the first longitudinal fold FL1 and the second longitudinal fold FL2 in the width direction. At the time of opening, the opening force is easily applied to both sides in the width direction of the absorbent article 1, and the absorbent article is easily developed due to the difference in rigidity.

Further, the main body sheet 61 and the flap sheet 62 are arranged between the first longitudinal fold FL1 and the second longitudinal fold FL2 in the width direction in a state of being folded along the first longitudinal fold FL1 and the second longitudinal fold FL2. Has been. Therefore, in the state which the absorbent article 1 and the packaging sheet 70 were folded, the durable strength in the case of being pressed from the side increases. For example, even when the package 100 of the absorbent article is gripped in the hand, the main body sheet 61 or the like suppresses the compressive deformation inward in the width direction, and the upper absorbent core that becomes the absorbent core is less likely to be crushed. . Therefore, the twist at the time of use of an absorbent article can be suppressed.

The area of the main body sheet 61 and the flap sheet 62 with respect to the packaging sheet 70 in the expanded state is 50% or more from the viewpoint of effectively improving the operability during folding and unfolding with the main body sheet 61 and the flap sheet 62. It is desirable.

Further, since the main body bonding region 65 and the flap bonding region 66 are provided in the longitudinal direction L and are provided in plural, a force for maintaining the flap portion 1B in a smooth state is propagated along the longitudinal direction L, and the flap is It becomes easy to maintain the whole in a smooth state. Therefore, when the absorbent article 1 is removed from the packaging sheet 70, it is possible to suppress problems such as the flap portion 1 </ b> B coming in and sticking the adhesive region.

Further, of the main body sheet 61 and the flap sheet 62, at least the surface of the main body sheet 61 on the adhesion region side is preferably a resin or paper having a higher melting point than the packaging sheet 70. According to such a configuration, when a hot melt adhesive is used as the adhesive, only the packaging sheet may be partially extended by heat depending on the temperature of the hot melt adhesive. For example, the packaging sheet is stretched by heat, and the stretched portion of the packaging sheet gathers in a portion (region between the main body adhesion regions 65) that is not fixed by the hot-melt adhesive, so that wrinkles are generated. Is formed. In FIG. 3, the uneven | corrugated | grooved part of the packaging sheet 70 is shown typically.

When a part of the packaging sheet 70 is melted and extended, and an uneven part due to wrinkles is formed, the entire surface of the packaging sheet is not flat, and an uneven part is partially formed. Therefore, when a wearer uses an absorbent article, it becomes possible to grasp | ascertain the part contact | abutted with underwear with a touch, and a wearability improves. In addition, since the main body adhesion region 65 and the flap adhesion region 66 extend in the longitudinal direction and are provided at intervals in the width direction, when the finger is moved along the width direction in order to spread the packaging sheet 70 The finger is easily caught and the operability is improved.

In addition, since the concavo-convex portion is formed on the packaging sheet, when the absorbent article package is transported, such as when packing the absorbent article package, the contact area with the transport surface is reduced, and friction is reduced. Can be reduced. Therefore, workability at the time of packing improves. In addition, the accommodation aspect to the accommodation bag which is a packing operation | work is demonstrated in detail later.

Furthermore, since the thickness of the part to which the adhesive is applied is larger than the part to which the adhesive is not applied, the adhesive region part is lifted in a state where the absorbent article 1 is wrapped by the packaging sheet 70. Therefore, when a wearer uses an absorbent article, it becomes possible to grasp | ascertain the part contact | abutted with underwear with a touch, and a wearability improves.

In general, a resin having a high melting point has high rigidity, and the rigidity of the main body sheet 61 is higher than that of the packaging sheet 70. In order to form a crease in the low-rigidity packaging sheet 70 without providing a crease in the high-rigidity body sheet, the packaging sheet 70 is flexibly folded while forming the folds while ensuring rigidity by the main body sheet 61, and smoothly folded. Can do.

The area ratio of the main body adhesion region 65 to the main body sheet 61 is preferably 50% or more, and the area ratio of the flap adhesion region to the flap sheet is preferably 50% or more. It is because it becomes easy to maintain the external shape of the package of an absorbent article in the folded state, so that the area ratio of an adhesion | attachment area | region is high.

Further, in order to improve the operability at the time of wearing, it is desirable that the flap adhesion region 66 is provided in front of the center in the longitudinal direction. Generally, when opening a package of folded absorbent articles by hand, fix between the first width fold and the second width fold with the base of the thumb of one hand and the other four fingers. . From that state, the portion (the region on the front side of the second width fold) arranged with the thumb is opened. That is, the opening operation is performed by bringing a finger or the like into contact with the front side of the longitudinal center. Since the flap adhesion region 66 is provided in the portion that is touched during the opening operation, the unevenness of the packaging sheet 70 makes it difficult for the hand to slip, and the opening operation can be easily performed.

Moreover, it is preferable that the fabric weight of the adhesive agent which adhere | attaches the packaging sheet 70, the main body sheet | seat 61, and the flap sheet | seat 62 is 20 g / m < ² > or more and 100 g / m < ² > or less. For example, when the basis weight of the adhesive is 20 g / m ² or less, the basis weight is low, and the uneven portion is hardly formed. On the other hand, when the basis weight of the adhesive is 100 g / m ² or more, the basis weight is high, the uneven portion on the surface of the packaging sheet becomes too high, and the smoothness of the surface of the packaging sheet may not be maintained.

Furthermore, the coating method of the hot melt adhesive is preferably a coater coating that is easy to apply with a certain width. In coater coating, the adhesive is released from the tip of the comb-shaped member, and the adhesive is applied to the object to be coated. According to the coater coating, the adhesive is applied with a constant width with a certain interval. Since the application length can be set as appropriate, the application can be performed at a predetermined length.

Furthermore, the adhesive tape 75 is arranged at the approximate center in the width direction of the packaging sheet 70 and in the center in the width direction in a state where the absorbent article and the package are folded. One end of the adhesive tape 75 is a front end portion in the longitudinal direction L and is attached to a portion of the packaging sheet 70 where the main body adhesion region 65 is not provided. That is, the adhesive tape 75 is affixed to a portion of the packaging sheet 70 where the uneven portion is not formed. Therefore, one end of the adhesive tape 75 can be made difficult to peel off from the packaging sheet 70, and the unfolding operation can be easily performed. In addition, in order to ensure the sticking area | region of an adhesive tape, it is desirable to comprise so that the main body adhesion | attachment area | region 65 may not be provided in a fixed area | region (for example, 10 mm) from the longitudinal direction edge part of a packaging sheet.

On the other hand, the other end of the adhesive tape 75 is configured to be affixed to a portion of the packaging sheet 70 where the main body adhesion region 65 is provided. The other end of the adhesive tape 75 is affixed to the portion of the packaging sheet 70 where the concavo-convex portion is formed. Therefore, the adhesive force between the adhesive tape and the top sheet can be weakened, and the adhesive tape 75 can be easily peeled off from the packaging sheet 70 during deployment.

Next, how the absorbent article folded in this way is accommodated in the accommodation bag of the packaging body will be described. FIG. 6 is a diagram schematically showing a manner of housing the absorbent article package in the housing bag. The storage bag is a bag that stores a plurality of absorbent article packages, and is not limited to the bag shape shown in FIG. 6.

The storage bag 200 has an opening 210 serving as an entrance for storing a package of absorbent articles. When the absorbent article packaging body 100 is accommodated in the accommodation bag 200, a plurality of absorbent article packaging bodies are accommodated in a state of being stacked in the thickness direction. When the absorbent article packaging bodies are arranged so as to overlap in the thickness direction, the concavo-convex portions of the packaging sheet due to the main body adhesion region are engaged with each other, and the displacement of the absorbent article packaging bodies can be prevented.

Further, when a plurality of absorbent article packages are accommodated in the accommodation bag, for example, they can be placed in the accommodation bag in the direction of the absorbent article package shown in FIGS.

6A, the longitudinal direction L of the absorbent article packaging body is along the long side 211 of the opening portion 210 of the containing bag, and the width direction W of the absorbent article packaging body 100 is the short side 212 of the containing bag. The state which accommodates the package 100 of an absorbent article in the accommodation bag 200 is shown in the state arrange | positioned so that it may follow. According to this accommodation mode, the uneven | corrugated | grooved part of a packaging sheet mutually engages, and the shift | offset | difference of the packaging bodies of an absorbent article is suppressed. Furthermore, since only the side surface of the absorbent article packaging body comes into contact with the inner surface of the accommodation bag when accommodated in the accommodation bag, the contact area between the absorbent article packaging body and the accommodation bag is small. Therefore, friction between the package of the absorbent article and the storage bag can be reduced and stored smoothly.

In FIG. 6B, the thickness direction T of the absorbent article packaging body 100 is along the long side 211 of the opening 210, and the width direction W of the absorbent article packaging body 100 is on the short side 212 of the containing bag 200.

According to this accommodation mode, the uneven | corrugated | grooved part of a packaging sheet mutually engages, and the shift | offset | difference of the packaging bodies of an absorbent article is suppressed. Furthermore, since the absorbent article packaging body is accommodated in the accommodation bag along the longitudinal direction of the absorbent article packaging body, the absorbent article packaging body is smoothly accommodated along the uneven portion extending in the longitudinal direction of the packaging sheet. can do.

6C, the width direction W of the absorbent article packaging body 100 is along the long side 211 of the opening 210, and the thickness direction T of the absorbent article packaging body 100 is along the short side 212 of the containing bag 200. FIG. The state which accommodates the package body of an absorbent article in the accommodation bag 200 in the state arrange | positioned along is shown. According to this accommodation mode, the uneven | corrugated | grooved part of a packaging sheet mutually engages, and the shift | offset | difference of the packaging bodies of an absorbent article is suppressed. Furthermore, since the absorbent article packaging body is accommodated in the accommodation bag along the longitudinal direction of the absorbent article packaging body, the absorbent article packaging body is smoothly accommodated along the concave and convex portions extending in the longitudinal direction of the packaging sheet. can do.

As described above, when storing the package of absorbent articles in the storage bag, in order to prevent positional displacement between the package of absorbent articles, the concavo-convex part of the packaging sheet by the main body adhesion region is at least It is desirable that two or more rows be adjacent to each other in the width direction.

Furthermore, it is desirable that the concavo-convex portions of the packaging sheet due to the main body adhesion region are formed on both surfaces of the packaging sheet in a state where the package of the absorbent article is folded by the first width fold and the second width fold. The term “both surfaces” as used herein refers to the surface of the absorbent article packaging body on which the adhesive tape is applied and the opposite surface (the surface located outside the region between the first and second width folds). ). Since the concavo-convex portions of the packaging sheet are formed on both surfaces, the packaging sheet of the absorbent article in contact with any surface can be meshed, and displacement can be suppressed.

The specific dimensions of the concavo-convex portion of the packaging sheet are preferably, for example, the width of the concave portion is 5 mm or less and the pitch of the concavo-convex portion is 10 mm or less. This is because if the width and pitch of the uneven portions are too long, the amount of displacement when the packaging bodies of the absorbent article are engaged with each other may increase.

Furthermore, the depth of the recess is desirably 1 mm or less.
