JP 2007-98037 A

  The absorbent article disclosed in Patent Document 1 can be appropriately positioned between the wearer's crotch by holding the absorbent article between the wearer's crotch while holding the knob. As a result, it is possible to prevent side leakage due to the displacement of the absorbent article while the wearer wears the absorbent article. However, there is still room for improvement in terms of preventing side leakage.

  In the absorbent article which has a flap, in order to prevent a side leak, it is desirable that the flap stands up firmly with the wearer wearing the absorbent article. However, the present inventors have noticed that there may be a situation where the flap does not stand up firmly when wearing the absorbent article, and if the absorbent article is worn with the flap lying down, the wearer wears the absorbent article. It has been found that the flap does not stand up toward the wearer's skin when it is done and the flap may not function sufficiently as a leak-proof wall.

  In view of the above circumstances, the present invention provides an absorbent article capable of easily starting up a flap when the absorbent article is mounted.

  That is, the absorbent article of the present invention has a width direction and a longitudinal direction, and includes a top sheet, a back sheet, an absorbent core provided therebetween, and flaps provided on both sides of the absorbent core in the width direction. The auxiliary sheet is provided with an auxiliary sheet on the outer surface of the back sheet, and a part of the auxiliary sheet is bonded to the back sheet and the other part is not bonded to the back sheet. A pocket for inserting a finger is formed, and the pocket is provided on both sides of the center line in the width direction of the absorbent article. Since the absorbent article of the present invention is provided with pockets on both sides of the center line in the width direction of the absorbent article on the outside of the backsheet, the caregiver, the wearer, etc. By inserting a finger into the absorbent article, it is naturally urged to pull the absorbent article in the longitudinal direction with the depression in the vicinity of the center in the width direction of the absorbent article. It will be easy to launch. Therefore, the absorbent article of the present invention can effectively prevent side leakage such as urine.

  The opening of the pocket is preferably in a region of 領域 of the longitudinal length of the absorbent core from the longitudinal end of the absorbent core. If the pocket is provided at such a position, the user (caregiver, wearer, etc.) can easily pull the absorbent article in the longitudinal direction by inserting a finger into the pocket.

  The pockets are preferably provided on both sides of the center line in the width direction of the absorbent article. If the absorbent article is provided on both sides of the center line in the width direction of the absorbent article, it is easy to insert a finger into the pocket and dent the absorbent article in the vicinity of the center line in the width direction. Therefore, when the finger is inserted into the pocket and the absorbent article is pulled in the longitudinal direction, the absorbent article can be easily formed in a state where the vicinity of the center in the width direction is depressed, and the flap is easily raised. Moreover, it becomes easy to grasp the absorbent article in a state in which a finger is inserted into the pocket and the absorbent article is bent near the center line in the width direction.

  The center line of the width of the pocket extending toward the opening is inward in the width direction parallel to the width direction of the absorbent article, or inward in the longitudinal direction parallel to the longitudinal direction of the absorbent article, or absorbed. It is preferable that the adhesive article is directed inward in the width direction and inward in the longitudinal direction. If the pocket is formed in this way, it becomes easy to insert a finger into the pocket while the absorbent article is folded in the width direction, or it is easy to pull the absorbent article in the longitudinal direction when the finger is inserted into the pocket. .

  The flap has a fixed part joined to the top sheet or / and the back sheet, an upright part extending from the fixed part, and an upright base at the boundary between the fixed part and the upright part, and the opening of the pocket is wider than the upright base. It is preferable that it is located inside. If the pocket is provided in such a positional relationship with respect to the upright base portion of the flap, the absorbent article is placed in the longitudinal direction with a finger inserted into the pocket and recessed near the center in the width direction of the absorbent article. By pulling, the upright portion of the flap is likely to rise upward.

  The pocket may be formed so that the inserted finger can pass therethrough. If the pockets are formed in this way, the auxiliary sheet can be provided with a smaller area, and the absorbent article can be manufactured at a low cost. Moreover, it becomes easy to move the finger inserted into the pocket relatively freely, and the handleability of the absorbent article is improved.

  The auxiliary sheet is preferably colored in a color different from that of the back sheet. If the auxiliary sheet is colored with a different color from the back sheet, the user can easily recognize the pocket.

  It is preferable that the absorbent article is folded at the center line in the width direction and folded in two in the width direction, and the pockets are provided symmetrically with respect to the center line in the width direction. By placing the absorbent article in such a state before use, the user can immediately recognize the pocket and can easily insert a finger into the pocket. And a flap comes to stand up naturally by unfolding folding of an absorptive article, putting a finger in a pocket.

  When the absorbent article is folded in half in the width direction, it is preferable that the end in the longitudinal direction is temporarily fixed. If the absorbent article is temporarily fastened at the end in the longitudinal direction, the absorbent article is easily maintained in a state of being folded in the width direction until the absorbent article is used. And when using an absorptive article, it becomes easy for a user to insert a finger in a pocket.

  The absorbent core may have one opening extending in the longitudinal direction on the center line in the width direction, or two openings extending in the longitudinal direction on both sides of the center line in the width direction so that the separation distance is within 40 mm. preferable. If the absorbent core is thus provided with an opening, the absorbent article can be folded back along the center line in the width direction and can be easily folded in two in the width direction.

  The absorbent article is preferably folded in two in the width direction and further folded in two or more in the longitudinal direction so that the pocket is exposed to the outside. If the absorbent article is folded in this way, the user can easily recognize the pocket even in the folded absorbent article.

  Since the absorbent article of the present invention is provided with a pocket on the outside of the back sheet, when the absorbent article is mounted, a caregiver or a wearer inserts a finger into the pocket, so that the width of the absorbent article is increased. It is naturally urged to pull the absorbent article in the longitudinal direction with the vicinity of the center of the direction depressed, and the flap can be easily raised by pulling the absorbent article. Therefore, the absorbent article of the present invention can effectively prevent side leakage such as urine.

The top view which looked at the absorbent article (urine pad) from the top sheet side as one embodiment of the absorbent article of this invention is represented. The top view which looked at the absorptive article shown in Drawing 1 from the back sheet side is expressed. The AA sectional view of the absorptive article shown in Drawing 1 and Drawing 2 is expressed. The BB sectional drawing of the absorptive article shown in Drawing 1 and Drawing 2 is expressed. 1 shows a state in which the absorbent article shown in FIG. 1 is used by being pulled in the longitudinal direction in a state where the vicinity of the center in the width direction is recessed. The structural example of an auxiliary | assistant sheet | seat and a pocket is represented. The absorbent article folded in half in the width direction is represented. The absorbent article is folded in two in the width direction and further in three in the longitudinal direction.

  The absorbent article of the present invention has a width direction and a longitudinal direction, and has a top sheet, a back sheet, and an absorbent core provided therebetween. Examples of the absorbent article of the present invention include urine pads (including incontinence pads), disposable diapers, sanitary napkins and the like.

  The longitudinal direction of the absorbent article means a direction extending in the front-rear direction of the wearer's crotch when the wearer wears the absorbent article. The width direction of the absorbent article means a direction that is on the same plane as the absorbent article in a state where the absorbent article is spread on a plane and is orthogonal to the longitudinal direction. Moreover, in this invention, the upper side means the wearer side at the time of wearing an absorbent article, and a lower side means the opposite side, ie, an outer side, from the wearer at the time of wearing an absorbent article. A surface formed on the outside is referred to as an outer surface. The direction extending from the upper side to the lower side or the opposite direction is referred to as the thickness direction.

  The shape of the absorbent article is not particularly limited. When the absorbent article is, for example, a urine pad or a sanitary napkin, the shape of the absorbent article includes a substantially rectangular shape, a rounded rectangle, an hourglass shape, a gourd shape, a battledore shape, and the like. When the absorbent article is a disposable diaper, a pair of fastening members are provided on the left and right, and an open-type disposable diaper that is formed into a pants shape when worn by the fastening member is suitably applied as the absorbent article of the present invention. it can.

  The top sheet is a sheet located on the wearer side when the absorbent article is worn, and is preferably liquid permeable.

  The back sheet is a sheet located on the side opposite to the wearer when the absorbent article is worn, that is, on the outside, and may be liquid permeable or liquid impermeable. For example, in the case of an auxiliary urine pad in which the absorbent article is used over another absorbent article, the backsheet may be liquid permeable. In general, the back sheet is preferably liquid-impermeable. In the present invention, liquid impermeability includes the meaning of water repellency.

  Examples of liquid-permeable sheets include nonwoven fabrics formed from hydrophilic fibers such as cellulose, rayon, and cotton; polyolefins (eg, propylene, polyethylene), polyesters (eg, PET), polyamides (eg, nylon), and the like A non-woven fabric formed from a hydrophobic fiber having a hydrophobic surface hydrophilized with a surfactant can be used. As the top sheet, a woven fabric, a knitted fabric, or a plastic film in which holes are formed may be used.

  As the liquid-impermeable sheet, it is possible to use a nonwoven fabric formed from hydrophobic fibers such as polyolefin (eg, propylene, polyethylene), polyester (eg, PET), polyamide (eg, nylon), a plastic film, or the like. it can. Moreover, you may use the laminated body of a nonwoven fabric and a plastic film.

  When a nonwoven fabric is used as the material of each sheet described above, the nonwoven fabric is preferably manufactured by a spunbond method, an air-through method, a point bond method, a melt blow method, an airlaid method, or a combination of these methods. Moreover, you may use the nonwoven fabric manufactured by SMS method which combined the spun bond method and the melt blow method.

  The absorbent core is not particularly limited as long as it includes an absorbent material that can absorb excrement such as urine. As the absorbent core, for example, a molded body obtained by molding the absorbent material into a predetermined shape is used, or the absorbent material is covered with a sheet member such as a paper sheet (for example, tissue paper or thin paper) or a liquid-permeable nonwoven sheet. Can be used. Examples of the absorbent material contained in the absorbent core include hydrophilic fibers such as cellulose fibers (for example, pulverized pulp fibers), polyacrylic acid-based materials, polyaspartic acid-based materials, cellulose-based materials, starch-acrylonitrile-based materials, and the like. Water-absorbing resin etc. are mentioned. In addition, the water-absorbing material may include heat-fusible fibers such as polyolefin fibers such as polyethylene and polypropylene, polyester fibers such as PET, and polyamide fibers such as nylon. These heat-fusible fibers may be subjected to a hydrophilic treatment with a surfactant or the like in order to increase the affinity with body fluid such as urine.

  It is preferable that an absorptive material contains a hydrophilic fiber from the point which improves the absorption speed | rates, such as urine. Moreover, it is preferable that an absorptive material contains a water absorbing resin from the point which raises absorption capacity. As the absorbent material, for example, it is preferable to use a material in which a water-absorbing resin is mixed or dispersed in an aggregate of hydrophilic fibers.

  The shape (planar shape) of the absorbent core is not particularly limited. The shape of the absorbent core may be appropriately determined depending on the application, and examples thereof include a substantially rectangular shape, an hourglass shape, a gourd shape, and a battledore shape.

  In the absorbent article, flaps are provided on both sides in the width direction of the absorbent core (that is, both left and right sides). Since the absorbent core is generally provided across the center line in the width direction of the absorbent article, the flaps are provided on both sides of the center line in the width direction of the absorbent article. For example, the flaps may be provided on both sides of the absorbent core on the upper side of the absorbent core, or may be provided on both outer sides in the width direction of the absorbent core. The flaps may be formed by raising the inner ends of the side sheets provided on both sides of the top sheet in the width direction. By providing the flaps, leakage preventing walls are formed on both sides of the absorbent core in the width direction, and side leakage of excrement such as urine can be prevented. The flap and the side sheet are preferably liquid-impermeable.

  The flap includes a fixed portion that is joined to the top sheet and / or the back sheet, and an upright portion that extends from the fixed portion. The flap is joined to the top sheet and / or the back sheet at the fixed portion, and the standing portion extends inward in the width direction from the fixed portion. The fixing portion is joined to, for example, the top sheet, the back sheet folded back on the top sheet, or both the top sheet and the back sheet. The standing part is not joined to either the top sheet or the back sheet, and the leakage preventing wall is formed by the standing part rising from the standing base. A standing elastic member is preferably provided at the inner end of the standing portion, and the flap rises toward the wearer's skin due to the contraction force of the standing elastic member, so that a leak-proof wall is easily formed.

  The end portion in the longitudinal direction of the flap may be bonded to the top sheet, for example, over the entire width direction, which makes it easier for the flap to rise toward the wearer's skin.

  By the way, it is desirable for the absorbent article having a flap to make the flap stand up firmly when being put on the wearer's crotch. This is because when the absorbent article is mounted while the flap is in a collapsed state, when the wearer wears the absorbent article, the flap does not rise toward the wearer's skin, and the flap may not function sufficiently as a leak-proof wall. . Therefore, before taking out the absorbent article from, for example, a packaging container and placing the absorbent article between the wearer's crotch, the caregiver or the wearer himself pulls the absorbent article in the longitudinal direction to raise the flap. It is preferable to do.

  Therefore, the absorbent article of the present invention is provided with an auxiliary sheet on the outer surface of the back sheet, and a pocket for inserting a finger is formed between the auxiliary sheet and the back sheet. The pocket is formed by joining a part of the auxiliary sheet to the back sheet and not joining the other part to the back sheet, and is provided on both sides of the center line in the width direction of the absorbent article. The pockets may be provided on both sides of the center line in the width direction of the absorbent article (separately), or may be provided on both sides of the center line in the width direction of the absorbent article so as to straddle the center line. . Since the absorbent article of the present invention has pockets on both sides of the center line in the width direction of the absorbent article on the outside of the backsheet, a user (caregiver, wearer, etc.) inserts a finger into the pocket By doing so, it is naturally urged to pull the absorbent article in the longitudinal direction in a state where the vicinity of the center in the width direction of the absorbent article is depressed, and the flap can be easily raised by pulling the absorbent article. Will be able to. Further, by placing the absorbent article between the wearer's crotch while inserting a finger into the pocket, the absorbent article can be accurately positioned without being displaced.

  The pocket is preferably provided in the vicinity of the end in the longitudinal direction of the absorbent article. Specifically, the opening of the pocket is a region that is 1/3 of the longitudinal length of the absorbent core from the longitudinal end of the absorbent core (more preferably, 1 of the longitudinal length of the absorbent core). / 4 region). If the pocket is provided at such a position, the user can easily pull the absorbent article in the longitudinal direction by inserting a finger into the pocket.

  A pocket should just be provided in the at least one side of the longitudinal direction of an absorptive article. For example, if a pocket is provided on one side of the absorbent article and no pocket is provided on the other side, by inserting a finger into the pocket provided on one side and grasping the other side of the absorbent article by hand, What is necessary is just to pull an absorbent article to a longitudinal direction. Moreover, it is also preferable that the pocket is provided on both one side and the other side in the longitudinal direction of the absorbent article. If pockets are provided in this way, a state in which the vicinity of the center in the width direction of the absorbent article is depressed by inserting a finger into both the pocket provided on one side and the pocket provided on the other side Thus, the absorbent article can be easily pulled in the longitudinal direction.

  The number of pockets provided in the absorbent article is not particularly limited. The number of pockets provided on one side (or the other side) in the longitudinal direction of the absorbent article is not particularly limited, but one or two is preferable. When one pocket is provided on one side (or the other side) in the longitudinal direction of the absorbent article, the pocket is preferably provided so as to straddle the center line in the width direction of the absorbent article. When two pockets are provided on one side (or the other side) in the longitudinal direction of the absorbent article, the pockets are preferably provided on both sides of the center line in the width direction of the absorbent article. That is, it is preferable that one pocket is provided on each of the one side and the other side across the center line in the width direction. The center line in the width direction of the absorbent article is a line that bisects the absorbent article in the width direction and extends in the longitudinal direction of the absorbent article. If one pocket is provided so as to straddle the center line in the width direction of the absorbent article, or if the pocket is provided on both sides of the center line in the width direction of the absorbent article, insert the finger into the pocket and the absorbent article Is easily recessed near the center line in the width direction. Therefore, when the finger is inserted into the pocket and the absorbent article is pulled in the longitudinal direction, the absorbent article can be easily formed in a state where the vicinity of the center in the width direction is depressed, and the flap is easily raised. Insert the fingers into the pocket and bend the absorbent article near the center line in the width direction. From this point, the pocket should be provided on both sides of the center line in the width direction of the absorbent article. More preferably.

  The pockets are preferably provided symmetrically with respect to the center line in the width direction of the absorbent article. If the pocket is provided as described above, the absorbent article can be stably pulled in the longitudinal direction with a finger inserted into the pocket and the vicinity of the center in the width direction of the absorbent article being depressed. Further, by inserting a finger into the pocket, it becomes possible to easily recognize the position of the center line in the width direction of the absorbent article without visually observing, and the absorbent article can be accurately positioned between the wearer's crotch become. In the present invention, the pockets are provided symmetrically with respect to the center line in the width direction of the absorbent article even when the pockets are symmetrical with respect to the center line in the width direction within 5 mm. .

  The opening of the pocket is preferably located on the inner side in the width direction than the standing base portion of the flap. If the opening of the pocket and the flap are in this positional relationship, the flap is inserted by inserting a finger into the pocket and pulling the absorbent article in the longitudinal direction with the center of the absorbent article recessed. Tends to rise upward rather than laterally. It should be noted that at least a part of the pocket opening may be located on the inner side in the width direction from the upright base portion of the flap, and is preferably located inward in the width direction with respect to the entire upright base portion of the flap.

  The shape of the pocket is not particularly limited as long as a finger can be inserted. The pocket may be formed so that the inserted finger can be penetrated, or the inserted finger may be formed so that the inserted finger cannot penetrate. In the former case, the pocket is formed in a ring shape (tunnel shape) composed of a back sheet and an auxiliary sheet, and has an opening for inserting a finger and an opening for the inserted finger to go out. If the pocket is formed in a ring shape, the auxiliary sheet can be provided in a smaller area, and the absorbent article can be manufactured at a low cost. Moreover, it becomes easy to move the finger inserted into the pocket relatively freely, and the handleability of the absorbent article is improved. In the latter case (when a pocket is formed so that the inserted finger cannot penetrate), the pocket is formed in a bag shape composed of a back sheet and an auxiliary sheet, and has only one opening for inserting the finger. It becomes. If the pocket is formed in a bag shape, the finger inserted into the pocket can be easily pressed by the auxiliary sheet, so that the absorbent article folded in the width direction can be reliably grasped.

  Non-woven fabric, woven fabric, knitted fabric, plastic film, etc. can be used as the auxiliary sheet for forming the pockets. However, from the viewpoint of easily obtaining a high-strength auxiliary sheet at low cost, it is possible to use non-woven fabric as the auxiliary sheet. preferable. Among these, it is preferable to use a spunbond nonwoven fabric, an SMS nonwoven fabric (a meltblown nonwoven fabric layer sandwiched between spunbond nonwoven fabric layers, including an SMMS nonwoven fabric), or an air-through nonwoven fabric as an auxiliary sheet. In addition, when using an air through nonwoven fabric, it has a merit in the touch of an auxiliary sheet becoming favorable rather than ensuring the intensity | strength of an auxiliary sheet.

When using a nonwoven fabric as an auxiliary sheet, the basis weight of the nonwoven fabric of the auxiliary sheet is preferably 15 g / m ² or more, and more preferably 30 g / m ² or more. When the basis weight of the nonwoven fabric of the auxiliary sheet is 15 g / m ² or more, the strength of the auxiliary sheet is easily secured. On the other hand, if the basis weight of the nonwoven fabric of the auxiliary sheet is too large, the production cost of the absorbent article is undesirably increased. Therefore, the basis weight of the nonwoven fabric of the auxiliary sheet is preferably 120 g / m ² or less, preferably 100 g / m ² or less. It is more preferable that

  The auxiliary sheet is preferably colored in a color different from that of the back sheet. If the auxiliary sheet is colored with a color different from that of the back sheet, the user can easily recognize a pocket formed by partially bonding the auxiliary sheet to the back sheet. Preferably, the auxiliary sheet is preferably colored in a color different from that of the back sheet, either the part not bonded to the back sheet or the part bonded to the back sheet.

  Next, the structural example of the absorbent article of this invention is demonstrated with reference to FIGS. The present invention is not limited to the embodiments shown in the drawings.

By placing the absorbent article 1 in such a state before use, the user can immediately recognize the pocket 15 and can easily insert a finger into the pocket 15. And the flap 6 comes to stand up naturally by unfolding the folding of the absorbent article 1 while putting a finger in the pocket 15.

  In order for the absorbent article 1 to be easily folded at the center line S in the width direction x, the absorbent core 4 is elongated on both sides of the center line S in the width direction x as shown in FIGS. It is preferable to have two openings 18 extending in the direction y. At this time, the distance between the two openings 18 is preferably within 40 mm (more preferably within 35 mm). Thus, if the opening 18 is provided in the absorptive core 4, it will become easy to fold the absorbent article 1 into the width direction x by using the part between the two openings 18 of the absorptive core 4 as a fulcrum. In this case, it is assumed that no clear crease is formed in the portion between the two openings 18 of the absorbent core 4, but it is not necessary to form a clear crease in the center line S. That is, when the absorbent article 1 is folded in two in the width direction x, the absorbent article 1 may not be formed with a clear fold in the center line S in the width direction x, and the fold may be rounded.

  Alternatively, the absorbent article 1 may have one opening extending in the longitudinal direction y on the center line S in the width direction x so that the absorbent article 1 can be easily folded at the center line S in the width direction x. Good (not shown). If the opening is provided in the absorbent core 4 as described above, the absorbent article 1 can be easily folded back at the portion where the opening is provided, and the absorbent article 1 is folded back at the center line S in the width direction x. It becomes easy to fold it in half.

  Further, if the absorbent core 4 is provided with an opening extending in the longitudinal direction y, urine and the like are easily diffused in the longitudinal direction y, and the absorbent core 4 is quickly absorbed. The shape of the opening is preferably a shape that is longer in the longitudinal direction y than the width direction x of the absorbent article 1, and examples thereof include a rectangle, an ellipse, a polygon, and a rectangle with rounded corners. Further, the width of the opening (the length in the width direction x) is preferably 5 mm or more, more preferably 10 mm or more, preferably 35 mm or less, and more preferably 30 mm or less.

  When the absorbent article 1 is folded in half in the width direction x, it is preferable that the end 19 of the absorbent article 1 in the longitudinal direction y is temporarily fixed. Specifically, it is preferable that the end portions 19 folded in half in the width direction x are temporarily fixed. If the absorbent article 1 is temporarily fastened at the end portion 19 in the longitudinal direction y, the absorbent article 1 is easily maintained in a state of being folded in the width direction x until the absorbent article 1 is used. When the absorbent article 1 is used, the user can easily insert a finger into the pocket 15.

  The method of temporarily fastening the end 19 is not particularly limited, and may be performed by, for example, heat sealing or application of an adhesive. At this time, it is preferable that the end 19 is intermittently heat-sealed or an adhesive is intermittently applied to the end 19 so that the temporary fastening can be easily released.

  The end 19 may be temporarily fastened by crimping the ends 19 folded in the width direction x. If the end 19 is temporarily fixed by crimping, the temporary fixing can be easily released, and when the temporary fixing is released, the temporarily fixed top sheet and the like are not easily damaged. Therefore, when the temporary fastening is released and the absorbent article 1 is worn, it becomes difficult for the wearer to feel discomfort due to the surface of the temporarily secured portion being roughened.

  As a method for producing an absorbent article that is folded in two in the width direction and whose end in the longitudinal direction is temporarily fixed, it is preferable to employ the following method. That is, the manufacturing method of the absorbent article is partially joined to the outer side of the back sheet and the top sheet, the back sheet, the absorbent core provided between them, the flaps provided on both sides of the absorbent core. A step of obtaining a laminated continuous sheet having a plurality of absorbent article units each having an auxiliary sheet (continuous sheet manufacturing step), a step of folding the laminated continuous sheet in two in the width direction (double folding step), and the folding It is preferable to have the process (individual cutting process) of cutting the laminated continuous sheet individually (each absorbent article unit) in this order. Under the present circumstances, it is preferable to provide the process of temporarily fixing an absorbent article at the edge part of a longitudinal direction as follows according to the method of temporary fixing.

  When the end in the longitudinal direction of the absorbent article is temporarily fixed by heat sealing, the laminated continuous sheets folded in two are continuously or intermittently extended in the width direction between the two-folding process and the individual cutting process. It is preferable to provide a step (heat sealing step) for heat-sealing in a linear form, and in the individual cutting step, the laminated continuous sheet is individually cut at the heat-sealed portion.

  When the end of the absorbent article in the longitudinal direction is temporarily fixed with an adhesive, a step of applying the adhesive to the laminated continuous sheet (adhesive application step) is provided before the folding process. It is preferable to perform a two-fold process later and to individually cut the laminated continuous sheet at the part where the adhesive is applied in the individual cutting process.

  When the end in the longitudinal direction of the absorbent article is temporarily fastened by pressure bonding, when cutting the laminated continuous sheet folded in the individual cutting step, it can be cut while pressing at the location where the laminated continuous sheet is cut. preferable. For example, the laminated continuous sheet folded in half is sandwiched between a cutting roll having a cutting blade on its surface and a flat roll to obtain an absorbent article that is temporarily cut at the end in the longitudinal direction and temporarily cut. Can do. If the end of the absorbent article in the longitudinal direction is temporarily fastened by such a method, it is preferable because it can be simply fastened.

  As shown in FIG. 8, the absorbent article 1 may be folded in two in the width direction x and further folded in two or more in the longitudinal direction y to form a folded absorbent article 21. In FIG. 8, the absorbent article 1 is folded in three in the longitudinal direction y to form a folded absorbent article 21. When the absorbent article 1 is further folded into two or more in the longitudinal direction y, the absorbent article 1 is folded in a compact manner, making it easy to carry the absorbent article 1 and carrying it in a container.

  The number of the absorbent article 1 folded in the longitudinal direction y is preferably 2 to 4 in that the thickness of the folded absorbent article 21 does not become too thick. In addition, the number of the folded absorbent article 21 in the longitudinal direction y is particularly three because the thickness of the folded absorbent article 21 does not become too thick and the size on the plane defined by the width direction x and the longitudinal direction y is compact. preferable.

  As shown in FIG. 8, the absorbent article 1 is preferably folded in the longitudinal direction y so that the pocket 15 is exposed to the outside to form a folded absorbent article 21. If the absorbent article 1 is folded in this manner, the pocket 15 can be easily recognized by the user even in the folded absorbent article 21.
