  As shown in FIG. 2, the absorbent article 1 has a specific portion 60 to which a fragrance material that releases a fragrance component by a predetermined stress is applied. The specific part 60 is provided at a position where a predetermined stress can be applied before the absorbent article 1 comes into contact with the wearer after the absorbent article 1 is taken out of the package. Here, the predetermined stress is a stress generated by rubbing the absorbent article 1, a stress generated by holding the absorbent article 1, and a stress generated by spreading the absorbent article 1.

  As described above, the perfume component released before the replacement start timing is worn by the predetermined stress applied before the timing when the absorbent article 1 contacts the wearer (exchange start timing) in the replacement of the absorbent article 1. Reach the person's nose. Thereby, a wearer can be made to smell a fragrance | flavor component repeatedly before an exchange start timing. In other words, in the replacement preparation stage of the absorbent article 1, the wearer can be made to smell the fragrance component repeatedly. Therefore, the wearer can be notified of the replacement start timing of the absorbent article 1.

  For example, when the absorbent article 1 is taken out from a package in which the absorbent article 1 is stored or a container that stores the absorbent article 1, the fragrance component diffuses due to a predetermined stress applied to the absorbent article 1 from the outside. . Thereby, the wearer can be notified of the replacement start timing of the absorbent article 1.

  The specific part 60 includes a microcapsule 60A that wraps the fragrance component. When a predetermined stress is applied to the microcapsule 60A, the microcapsule 60A is ruptured by the predetermined stress, and the fragrance component enclosed in the microcapsule 60A is diffused. That is, the microcapsule 60A is an example of a fragrance material that releases a fragrance component.

  The capsule membrane of the microcapsule 60A is made of, for example, a network polymer material. The capsule membrane generally has a spherical shape. A fragrance component is enclosed inside the capsule membrane.

  Examples of the material of the capsule membrane include polymer compounds such as polyurea, polyurethane, polyamide, melamine resin, urea resin, algin hydrochloric acid, gelatin, gum arabic, and starch (for example, JP 2008-063575 A, JP 2010). -001417 publication).

  The perfume ingredient includes oxytocin or an ingredient that induces oxytocin. The component that induces oxytocin preferably contains, for example, breast milk as a main component. Preferably, the component that induces oxytocin preferably contains the mother's milk of the mother of the wearer of the absorbent article 1 as a main component. Thus, since the component which induces oxytocin contains breast milk as a main component, the effect which makes a newborn feel comfortable can be expected.

  However, the component which induces oxytocin is not limited to this. For example, the component that induces oxytocin may include rose oil, ethyltrimethylcyclopentenylbutenol, methyltrimethylcyclopentenylpentanol, and hexahydrohexamethylcyclopentabenzopyran (for example, JP 2011-098898 A). .

  The specific portion 60 is preferably provided on the outermost surface (outermost surface) in the product thickness direction T. The outermost surface is the surface of the sheet provided on the outermost side (non-skin surface side) of the absorbent article 1 in the product thickness direction T. For example, it is the surface of the outermost sheet provided on the outer side (non-skin surface side) of the back sheet 4 (nonwoven fabric 4A and back film 4B). Or it is the surface of the back sheet 4 (nonwoven fabric 4A and back film 4B). In other words, the specific part 60 is exposed on the non-skin surface side in the product thickness direction T. Thereby, when taking out the absorbent article 1 from the package, the package or the like and the specific portion 60 are rubbed, and the fragrance component is easily released.

  Alternatively, the specific portion 60 is preferably provided on the innermost surface (innermost side surface) in the product thickness direction T. The innermost side surface is the surface of the sheet provided on the innermost side (skin surface side) of the absorbent article 1 in the product thickness direction T. For example, the innermost side surface is the surface of the top sheet 3. In other words, the specific part 60 is exposed on the non-skin surface side in the product thickness direction T. Thereby, the fragrance | flavor component tends to be discharge | released when the stress which may arise when the absorbent article 1 is expanded from the folded state is applied to the specific site | part 60. FIG.

  The specific portion 60 is configured by a nonwoven fabric that holds the microcapsules 60A. It is preferable that the surface of the nonwoven fabric which comprises the specific part 60 has an unevenness | corrugation. In detail, it is preferable that the fabric weight of the nonwoven fabric which comprises the specific part 60 is 15gsm-50gsm. Or it is preferable that a pressing part is provided in the surface of the nonwoven fabric which comprises the specific site | part 60. FIG. In such a case, it is preferable that the space | interval of a pressing part is 3 mm-10 mm. Moreover, it is preferable that the pressing rate of a pressing part is 20%-70%. However, the compression ratio is expressed by the height from the lower surface of the nonwoven fabric to the bottom surface of the concave portion / the height from the lower surface of the nonwoven fabric to the top surface of the convex portion × 100%.

  Thus, it is easy to hold | maintain a fragrance | flavor component by the specific site | part 60 being comprised with a nonwoven fabric. Moreover, when the surface of the nonwoven fabric which comprises the specific site | part 60 has an unevenness | corrugation, the surface area of the specific site | part 60 increases and a fragrance | flavor component tends to diffuse.

  The specific portion 60 is preferably provided at a position where a predetermined stress is applied in a preparation procedure for mounting the absorbent article 1 on the wearer before the absorbent article 1 contacts the wearer. For example, the specific part 60 is provided at a position overlapping the crotch region 10C in the product thickness direction T.

  Thus, in the preparatory procedure for mounting the absorbent article 1 on the wearer, the perfume can be applied with a predetermined stress by performing operations such as rubbing the crotch region 10C, holding the crotch region 10C, or expanding the crotch region 10C. Ingredients are released. Therefore, in preparation for mounting the absorbent article 1 on the wearer, the wearer can smell the fragrance component without requiring a special operation such as changing the absorbent article 1 or peeling off some sheet. . In other words, the wearer prepares for replacement of the absorbent article 1 without taking his gaze away from the wearer (the wearer comes into contact with the absorbent article 1 in the absorbent article 1 enclosed in the package, and the absorbent article from the package. In the preparation of the wearer holding the absorbent article 1 when taking out 1 and the wearer shaking the absorbent article 1 to open the absorbent article 1), the wearer does not need any special action. The fragrance component can be smelled repeatedly. Thereby, the flow that the replacement of the absorbent article 1 starts after the wearer smells the fragrance component becomes customary for the wearer.

  The locking tape 40 is attached to the end 20a of the rear waistline sheet 20 by HMA or the like.

  For example, the locking tape 40 includes a male member of a hook-and-loop fastener, and has a locking surface 40a on which a plurality of hook-shaped protrusion groups (hooks) are formed. The locking surface 40 a is locked to the target tape portion 10 t provided on the end portion 10 a 2 of the crotch sheet 10. In 1st Embodiment, the part of the other locking tape 40 except the locking surface 40a is formed with SB nonwoven fabric. In addition, as a raw material of the locking tape 40, a resin film etc. are mentioned besides SB nonwoven fabric.

  Here, when providing the specific site | part 60 as a part of latching tape 40, a part of latching tape 40 is comprised with the nonwoven fabric, and the component which induces oxytocin or an oxytocin may be provided to a nonwoven fabric. preferable.

FIG. 5 is a diagram illustrating a state in which the wearer W wears the absorbent article 1. As shown in FIG. 5, the absorbent article 1 is attached to the wearer W so that the absorbent body 5 is positioned in the crotch WG of the wearer W.

  A wearer (not shown) who wears the absorbent article 1 on the wearer W pulls the locking tape 40 toward the wearer's stomach, and the pulled locking tape 40 is applied to the target tape portion 10t of the crotch sheet 10. Lock. Thereby, it wears on wearer W.

(Method for manufacturing absorbent article)
Below, the manufacturing method of the absorbent article 1 which concerns on 1st Embodiment is demonstrated. Here, in particular, a method for manufacturing the rear waistline sheet 20 and the front waistline sheet 30 will be mainly described. In addition, other parts, such as the inseam sheet | seat 10, can be manufactured in accordance with a well-known manufacturing method.

  FIG. 6 is a diagram schematically illustrating a manufacturing process of the absorbent article 1. As shown in FIG. 6, the manufacturing process of the absorbent article 1 includes a first folding step S10, a second folding step S20, a locking tape applying step S30, a first cutting step S40, and a flap applying step S50. And a second cutting step S60.

  In the first folding step S10, the end portion 130c and the end portion 130d of the flap sheet 130S that are continuous along the transport direction MD are folded toward the upper surface 130e of the flap sheet 130S toward the center line CL side of the flap sheet 130S. And bonded by HMA or the like. The center line CL is a straight line passing through the center of the product width direction W (direction orthogonal to the conveyance direction MD) of the flap sheet 130S.

  In the second folding step S20, the folded end portion 130f and the folded end portion 130g formed by folding the end measuring portion 130c and the end measuring portion 130d of the flap sheet 130S are directed toward the center line CL. Folded to the upper surface 130e side. As a result, an overlapping portion 130h and an overlapping portion 130i in which a plurality of flap sheets 130S are stacked are formed at both ends of the flap sheet 130S.

  In the locking tape sticking step S30, the tape member 40S in which the pair of locking tapes 40 is continuous is stuck to the flap sheet 130S at a predetermined interval along the transport direction MD. In the center of the tape member 40S, a process for facilitating the separation of the tape member 40S into a pair of locking tapes 40, such as a perforation 40c, is performed along the conveyance direction MD.

  In the first cutting step S40, the flap sheet 130S is cut at a predetermined interval along the intersecting direction CD perpendicular to the transport direction MD. The cut piece 32 from which the flap sheet 130 </ b> S is cut is obtained by integrating the rear waistline sheet 20 and the front waistline sheet 30.

  In flap sticking process S50, the cut piece 32 is arrange | positioned at predetermined intervals on the crotch region continuous body 10S. In the crotch region continuous body 10S, the absorbent body 5 is intermittently disposed on a continuous body of exterior sheets (top sheet 3 and back sheet 4). The cut pieces 32 are disposed on the crotch region continuous body 10S so as to cover the gaps between the absorbent bodies 5 disposed intermittently, and are joined to the crotch region continuous body 10S.

  In the second cutting step S60, the crotch region continuous body 10S to which the cut pieces 32 are joined is cut along the cross direction CD. The cut piece 32 is separated into a rear waistline sheet 20 of one product and a front waistline sheet 30 of the product following the one product. The absorbent article 1 is completed by executing the above-described steps S10 to S60.

  Here, the specific part 60 mentioned above is affixed beforehand to the crotch region continuous body 10S, the flap sheet 130S, and the tape member 40S.

(Amount of perfume ingredients released)
Below, the change of the discharge | release amount of the fragrance | flavor component which concerns on 1st Embodiment is demonstrated. FIG. 7 is a diagram illustrating a change in the amount of the fragrance component released according to the first embodiment.

  As shown in FIG. 7, in the replacement preparation stage, the amount of the fragrance component released from the fragrance material applied to the specific part 60 is the largest. The amount of perfume components released continues to decrease in the exchange and use phases. That is, the release amount of the fragrance component in the replacement preparation stage is larger than the release amount of the fragrance component in the replacement stage, and the release amount of the fragrance component in the replacement stage is larger than the release amount of the fragrance component in the use stage.

  Here, the replacement preparation stage is a stage from the time when the absorbent article 1 is taken out of the package to the timing when the absorbent article 1 contacts the wearer (exchange start timing). The exchange stage is a stage where the absorbent article 1 is exchanged. The use stage is a stage after the timing when the replacement of the absorbent article 1 is completed (exchange completion timing).

  Thus, in the replacement preparation stage (that is, before the absorbent article 1 comes into contact with the wearer), it is determined that the wearer is in the replacement preparation stage of the absorbent article 1 by peaking the amount of the fragrance component released. And the wearer can be made to smell the fragrance ingredient repeatedly.

(Function and effect)
In 1st Embodiment, the specific site | part 60 to which the fragrance | flavor substance was provided is provided in the position which can apply predetermined stress, before the absorbent article 1 contacts a wearer. Thereby, it is possible to release the fragrance component before the timing when the absorbent article 1 contacts the wearer (hereinafter referred to as the replacement start timing), and the fragrance is repeatedly given to the wearer before the replacement start timing. Ingredients can be smelled. In other words, in the replacement preparation stage of the absorbent article 1, the wearer can be made to smell the fragrance component repeatedly. Thereby, the wearer can be notified of the replacement start timing of the absorbent article 1. In particular, since the visual acuity of the newborn is not sufficiently developed, it is very effective to inform the newborn of the replacement start timing by releasing the fragrance component.

  Further, since the absorbent article 1 is disposable, it is possible to impart a fragrance component to the targeted position of each absorbent article 1 and to control the release timing of the fragrance component.

[Modification 1]
Hereinafter, Modification Example 1 of the first embodiment will be described. In the following, differences from the first embodiment will be mainly described.

  In the first embodiment, the crotch region 10C is exemplified as a position to which a predetermined stress is applied in the preparation procedure for mounting the absorbent article 1 to the wearer. That is, the case where the specific part 60 is provided in the crotch region 10C is illustrated.

  On the other hand, in the first modification, the fastening member is provided in one of the front waistline region 30F and the rear waistline region 20R, and the attachment region is provided in one of the front waistline region 30F and the rear waistline region 20R. Consider a case in which the absorbent article 1 is enclosed in a package in a state where the fastening member is fastened to the fastening region. In such a case, the specific portion 60 is provided in the fastening member (for example, the locking tape 40) or the secured region (for example, the target tape portion 10t).

  Here, the locking tape 40 is generally separate from the crotch sheet 10, the rear waistline sheet 20, and the front waistline sheet 30. Similarly, the target tape portion 10t is generally separate from the crotch sheet 10, the rear waistline sheet 20, and the front waistline sheet 30. That is, in the manufacturing process of the absorbent article 1, the specific portion 60 can be formed in advance on a separate member from the crotch sheet 10, the rear waistline sheet 20, and the front waistline sheet 30. The complexity of the manufacturing process is suppressed.

  Alternatively, in the case where the fastening member (for example, the locking tape 40) is fastened to the secured region (a region different from the target tape portion 10t) in a state where the absorbent article 1 is sealed in the package. In preparation for attaching the absorbent article 1 to the wearer, the fastening member is surely peeled off from the adherend region, so that the wearer can surely smell the fragrance component. That is, smelling and leaking of the fragrance component is suppressed.

[Modification 2]
Hereinafter, Modification Example 2 of the first embodiment will be described. In the following, differences from the first embodiment will be mainly described.
