The protruding length of the tape 41 in the left-right direction can be shortened. In addition, since the tip of the tape base 413 faces outward in the left-right direction, when the disposable diaper 1 is used, the operator can easily pick the tip of the tape base 413. Can be spread easily. Further, since the tip of the tape base 413 protrudes outward from the first folding line 431 in the left-right direction, the operator can more easily pick the tip of the tape base 413, so that the fastening tape 41 Can be more easily spread in the left-right direction.

  In the connection part 4, the second fastening part 412 is temporarily fastened to the inner surface 422 of the common base part 42, thereby preventing the folded fastening tape 41 from spreading in the manufacturing process of the disposable diaper 1. Is done. As a result, when the disposable diaper 1 is manufactured, it is possible to prevent the defective tape from being manufactured by fixing the fixing tape 41 to an unintended portion. Further, in the outer surface 418 of the tape base 413, the region between the first fold line 431 and the second fold line 432 and the region on the tip side of the tape base 413 with respect to the second fold line 432 are hot-melt bonded. By being temporarily fixed by the agent layer 44, it is possible to more easily prevent the fixing tape 41 from spreading in the manufacturing process of the disposable diaper 1. Furthermore, in the disposable diaper 1, the first folding line 431 overlaps or is close to the edge of the inner region 416 on the main body 2 side in the state before use, so that the fastening tape 41 protrudes in the left-right direction. The length can be made shorter.

  When the disposable diaper 1 is attached to the wearer, each fastening tape 41 spread in the left-right direction is fastened to the fastened part 26 of the front part 201 as shown in FIG. In the disposable diaper 1, each fastening tape 41 is fastened to the fastened part 26 by the first fastening part 411 and the second fastening part 412 (see FIG. 5) that are separated in the left-right direction. The tape 41 easily deforms following the wearer's movement. As a result, the fastening tape 41 is prevented from being peeled off from the secured portion 26 due to the wearer's movement or the like.

  When the disposable diaper 1 is larger than the wearer's body shape (for example, when the disposable diaper 1 is attached to a wearer who is thinner than a normal wearer), each connecting portion 4 1, after one of the two fastening tapes 41 arranged in the longitudinal direction of the main body is fastened to the fastened portion 26, the other fastening tape 41 attaches the one fastening tape 41. It is fixed to the to-be-attached part 26 so that it may straddle. In the present embodiment, a fastening tape (hereinafter referred to as “first fastening tape 41 a”) located on the upper side in FIG. 7 is attached to each connecting portion 4 with its tip inclined downward. A fastening tape (hereinafter referred to as “second fastening tape 41b”), which is fastened to 26 and located on the lower side in FIG. 7, overlaps the first fastening tape 41a with its tip inclined upward. In this state, it is secured to the secured part 26. Accordingly, the front part 201 and the rear part 203 fit around the waist of the wearer at both ends in the longitudinal direction of the body part 2, and both end parts of the body part fit near the base of the wearer's legs.

  FIG. 8 is an enlarged view showing the vicinity of one connection portion 4 of the pair of connection portions 4. As shown in FIG. 8, on the to-be-fixed part 26, the 1st fastening tape 41a and the 2nd fastening tape 41b which overlaps on the 1st fastening tape 41a cross | intersect substantially perpendicularly. That is, the first fastening tape 41a is set so that the angle θ formed by the center line 419a extending in the left-right direction of the first fastening tape 41a and the center line 419b extending in the left-right direction of the second fastening tape 41b is approximately 90 °. And the second fastening tape 41b intersect. The intermediate region 415 of the first fastening tape 41a overlaps the intermediate region 415 of the second fastening tape 41b, and the first fastening portions 411 disposed on both sides of the intermediate region 415 of the second fastening tape 41b and The second fastening portion 412 is fastened to the fastened portion 26 on both sides of the first fastening tape 41a in the tape width direction (that is, straddling the first fastening tape 41a). In FIG. 8, in order to facilitate understanding of the drawing, parallel diagonal lines are given to the first fastening portion 411 and the second fastening portion 412 of the second fastening tape 41b.

  In the disposable diaper 1, the length of the first fastening tape 41a and the second fastening tape 41b is used to facilitate handling when the disposable diaper 1 is mounted or to facilitate the manufacture of the disposable diaper 1. As a result, the distance L1 between the outer edge 4111 of the first fastening portion 411 and the inner edge 4122 of the second fastening portion 412 in each fastening tape (see FIG. 5). ) Also has an upper limit. In the connection part 4, a hook is provided between the first fastening part 411 and the second fastening part 412 in the second fastening tape 41 b that overlaps the first fastening tape 41 a when the fastening tape is stacked. By providing the intermediate region 415 to which the members are not joined, the total area of the fastening portions (that is, the first fastening portion 411 and the second fastening portion 412) can be reduced. Thereby, the manufacturing cost of the disposable diaper 1 can be reduced.

  Further, the distance L1 between the outer edge 4111 of the first fastening portion 411 of the second fastening tape 41b and the inner edge 4122 of the second fastening portion 412 is defined as the tape in the intermediate region 415 of the first fastening tape 41a. By making it larger than the width W1 of the base portion 413 (see FIG. 5), the first fastening portion of the second fastening tape 41b is used when the first fastening tape 41a and the second fastening tape 41b are fastened together. At least a part of each of the 411 and the second fastening part 412 can be easily fastened to the fastened part 26 without overlapping the first fastening tape 41a. As a result, the disposable diaper 1 can be fitted to the wearer.

  In the disposable diaper 1, also in the first fastening tape 41a, an intermediate region 415 where the hook member is not joined between the first fastening portion 411 and the second fastening portion 412 is provided in the same manner as the second fastening tape 41b. By providing, the total area of the 1st fastening part 411 and the 2nd fastening part 412 can be made small. Further, when the disposable diaper 1 is attached to the wearer, the first fastening tape 41a is overlapped on the second fastening tape 41b after the second fastening tape 41b is fastened to the fastened portion 26. Even when the first fixing tape 41a is fixed to the fixing portion 26, at least part of the first fixing portion 411 and the second fixing portion 412 of the first fixing tape 41a is fixed without overlapping the second fixing tape 41b. It is easily fixed to the portion 26.

  In the disposable diaper 1, in each fastening tape 41, between the upper end of the outer edge 4111 (see FIG. 5) of the first fastening portion 411 and the lower end of the inner edge 4122 (see FIG. 5) of the second fastening portion 412. Is preferably equal to or greater than the width W1 of the intermediate region 415. As a result, when the fastening tape 41 is overlapped, at least a part of each of the first fastening portion 411 and the second fastening portion 412 of the fastening tape 41 that overlaps the fastening portion of the front portion 201 is secured. The part 26 can be easily fixed.

  In the connection portion 4, the length L2 (see FIG. 5) of the intermediate region 415 of the second fastening tape 41b is equal to or greater than the width W1 of the intermediate region 415 of the first fastening tape 41a, so that the second fastening tape When the tape 41b is stacked on the first fastening tape 41a and fastened to the fastened portion 26, it is highly likely that the second fastening tape 41b will not be used for fastening (ie, the first fastening tape 41a). It can suppress that a fastening part is provided in the site | part which overlaps), and can make the total area of a fastening part smaller. Further, the length L2 of the intermediate region 415 of the first fastening tape 41a is equal to or greater than the width W1 of the intermediate region 415 of the second fastening tape 41b, so that the first fastening tape 41a is replaced with the second fastening tape. Fastened to the part 26 that is highly likely not to be used for fastening the first fastening tape 41a (ie, the part that overlaps the second fastening tape 41b) when it is piled on 41b and fastened to the fastened part 26 It can suppress that a part is provided and can make the total area of a fastening part smaller.

  In the disposable diaper 1, in each fastening tape 41, between the upper end of the inner edge 4112 (see FIG. 5) of the first fastening portion 411 and the lower end of the outer edge 4121 (see FIG. 5) of the second fastening portion 412. Is preferably equal to or greater than the width W1 of the intermediate region 415. Accordingly, when the fastening tape 41 is overlapped, it is possible to prevent the fastening portion from being provided in a portion that is highly likely not to be used for fastening the fastening tape 41 that is overlaid, and the total area of the fastening portion. Can be made smaller.

  When the fastening tape of the connecting portion 4 is stacked, the angle θ formed between the center line 419a of the first fastening tape 41a and the center line 419b of the second fastening tape 41b is not necessarily limited to about 90 °. For example, the angle θ (that is, the angle formed by the center lines 419a and 419b respectively extending from the intersection of the center line 419a and the center line 419b to the tips of the first fastening tape 41a and the second fastening tape 41b) is 30 °. The first fastening tape 41a and the second fastening tape 41b may be overlapped so as to be 90 ° or less.

  In the connection portion 4, the widths of the first fastening tape 41 a and the second fastening tape 41 b gradually decrease toward the tip of the tape base 413. For this reason, when the fastening tape is stacked, the fastening tape that is fastened later (that is, the fastening tape that is stacked on the other fastening tape and fastened to the fastened portion 26) is attached. The 1 fastening part 411 can be easily fastened to the fastened part 26 while avoiding the fastening tape fastened first. As a result, the leading end portion of the fastening tape that is later secured to the secured portion 26 can be firmly secured to the secured portion 26.

  In the connection part 4, the two tape bases 413 of the first fastening tape 41a and the second fastening tape 41b are a part of one connection part sheet 40 continuous on the main body part 2 side, and the first fastening tape 41a and the 2nd fastening part 412 of the 2nd fastening tape 41b are spaced apart and located in the outside of a horizontal direction rather than common base 42 of connecting part sheet 40. For this reason, it is prevented that the rigidity of the root portion of the first fastening tape 41a and the second fastening tape 41b (that is, the portion between the second fastening portion 412 and the common base portion 42) becomes excessively large. The first fastening tape 41a and the second fastening tape 41b can be easily deformed at the root portion. As a result, the first fastening tape 41a and the second fastening tape 41b can be easily stacked. Further, since the common base portion 42 protrudes laterally from the side edge of the main body portion 2, the common base portion 42 can be deformed to easily bring the first fastening tape 41a and the second fastening tape 41b closer to each other. it can. As a result, the first fastening tape 41a and the second fastening tape 41b can be more easily stopped.

  Furthermore, in the 1st fastening tape 41a and the 2nd fastening tape 41b, the position of the 1st fastening part 411 and the 2nd fastening part 412 can be visually recognized from the outer surface of the tape base 413, Therefore When overlapping the tape 41a and the second fastening tape 41b, the overlapping area of the intermediate region 415 of the two fastening tapes can be easily increased. In other words, the first fastening portion 411 and the second fastening portion 412 of the fastening tape that are later fastened to the fastened portion 26 are in a wide range with the fastening tape fastened earlier. It can prevent that it overlaps. As a result, it is possible to firmly fix the fastening tape that is later secured to the secured portion 26 to the secured portion 26.

  Next, the disposable diaper which concerns on the 2nd Embodiment of this invention is demonstrated. FIG. 9 is a plan view of a portion in the vicinity of the connecting portion 4 of the disposable diaper according to the second embodiment, and FIG. 10 is a cross section of the portion in the vicinity of the connecting portion 4 at a position CC in FIG. FIG. The disposable diaper according to the second embodiment has the same structure as the disposable diaper 1 according to the first embodiment, except that the folded shape of each fastening tape 41 in a state before use is different. In the following description, the same reference numerals as those of the corresponding configuration of the disposable diaper 1 shown in FIGS. 1 to 5 are attached to the configurations of the disposable diaper according to the second embodiment.

  As shown in FIGS. 9 and 10, the tape base 413 is a first region located in an intermediate region 415 between the first fastening part 411 and the second fastening part 412 in a state before the use of the disposable diaper 1. It is folded inward in the left-right direction at a folding line 431a. The first folding line 431a is parallel to the longitudinal direction of the main body, and the areas on both sides of the first folding line 431a on the inner surface 414 of the tape base 413 are opposed to each other by folding on the first folding line 431a. The first fold line 431 a substantially overlaps the outer edge 4121 of the second fastening portion 412, and the second fastening portion 412 is temporarily fastened to the intermediate region 415. The first folding line 431a may be close to the outer edge 4121 of the second fastening portion 412.

  The tape base 413 is further located in the intermediate region 415 on the tip side of the tape base 413 than the first fold line 431a, that is, between the first fold line 431a and the first fastening part 411. A second fold line 432 is provided. The second folding line 432 is parallel to the longitudinal direction of the main body, and the tape base 413 is folded outward in the left-right direction at the second folding line 432. Due to the folding at the second folding line 432, the regions on both sides of the second folding line 432 on the outer surface 418 of the tape base 413 face each other. Of the outer surface 418 of the tape base 413, the region between the first fold line 431a and the second fold line 432 and the region on the tip side of the tape base 413 with respect to the second fold line 432 are a hot melt adhesive layer. 44 (shown only in FIG. 10). Further, the tip of the tape base 413 faces in a direction away from the main body 2 (that is, the outer side in the left-right direction), and protrudes from the first folding line 431a toward the outer side in the left-right direction.

  In the disposable diaper according to the second embodiment, in the state before use, the tape base 413 of each fastening tape 41 is folded at the first folding line 431a and the second folding line 432 and folded into a Z shape. Therefore, the length of the fastening tape 41 protruding left and right can be shortened. Further, as in the first embodiment, the tip of the tape base 413 faces the outside in the left-right direction, so that the operator can easily pick the tip of the tape base 413 when using the disposable diaper. Therefore, the fastening tape 41 can be easily spread in the left-right direction. Furthermore, since the front end of the tape base 413 protrudes outward in the left-right direction from the first folding line 431a, the fastening tape 41 can be more easily spread in the left-right direction.

  In the connection part 4, since the 2nd fastening part 412 is temporarily fixed to the intermediate | middle area | region 415, it is prevented that the fastening tape 41 spreads in the manufacturing process of a disposable diaper. As a result, when the disposable diaper is manufactured, it is possible to prevent the defective tape from being manufactured by fixing the fixing tape 41 to an unintended portion. Further, in the outer surface 418 of the tape base 413, the region between the first fold line 431a and the second fold line 432 and the region on the tip side of the tape base 413 with respect to the second fold line 432 are hot-melt bonded. By being temporarily fixed by the agent layer 44, it is possible to more easily prevent the fixing tape 41 from spreading in the manufacturing process of the disposable diaper. Furthermore, in the disposable diaper, since the first folding line 431a overlaps or is close to the outer edge 4121 of the second fastening part 412 in the state before use, the length of the fastening tape 41 protruding to the left and right is increased. It can be made shorter.

  As shown in FIG. 9, in the disposable diaper in a state before use, a part of the second fastening part 412 (the central part in the longitudinal direction of the main body) overlaps with the intermediate region 415 of the tape base 413, and the second fastening part The other part of the part 412 (both ends in the longitudinal direction of the main body) does not overlap with the intermediate region 415 (that is, exposed from the intermediate region 415). In FIG. 9, a parallel oblique line is given to a portion 4123 of the second fastening portion 412 that does not overlap with the intermediate region 415.

  In the disposable diaper before use, as shown in FIGS. 11 and 12, the tape base 413 of each fastening tape 41 is arranged in the left-right direction at a third folding line 433 parallel to the longitudinal direction of the main body located in the inner region 416. The first fastening part 411 may be further folded back toward the inner side (that is, the main body part 2 side) so as to face the inner surface 422 of the common base part 42. FIG. 12 is a cross-sectional view in which a portion in the vicinity of the connection portion 4 is cut at a position DD in FIG. As shown in FIG. 11, the third folding line 433 substantially overlaps (or is close to) the boundary between the inner region 416 that is the edge of the inner region 416 on the main body 2 side and the common base portion 42.

  In the disposable diaper in a state before use, the exposed portion 4123 which is a portion not overlapping with the first fastening portion 411 and the intermediate region 415 of the second fastening portion 412 described above (the parallel oblique lines are also given in FIG. 11). Is temporarily fixed to the inner surface 422 of the common base portion 42 (that is, the inner region in the left-right direction with respect to the third folding line 433). Thereby, the protrusion length to the right and left of the fastening tape 41 can be further shortened, and the fastening tape 41 can be easily prevented from spreading. In FIGS. 11 and 12, the third fold line 433 overlaps the first fold line 431a, but the third fold line 433 and the first fold line 431a may be arranged close to each other and separated from each other. May be arranged.

  In the disposable diapers according to the first and second embodiments described above, in each fastening tape 41, the fastening strength per unit area of the first fastening portion 411 with respect to the secured portion 26 is the second fastening. The fixing strength per unit area of the portion 412 with respect to the fixing portion 26 is equal, and the width in the left-right direction of the first fixing portion 411 is equal to the width in the left-right direction of the second fixing portion 412. For this reason, the 1st fastening part 411 and the 2nd fastening part 412 can be formed with one elongate hook member, and manufacture of the connection part 4 can be simplified.

  In another example of the disposable diaper according to the present invention, the fastening strength of the first fastening part 411 with respect to the fastened part 26 is greater than the fastening strength of the second fastening part 412 with respect to the fastened part 26. In the disposable diaper, when a force in a direction to peel off the fastening tape 41 is applied, such as when the tape base 413 of the fastening tape 41 is caught on the clothes of the wearer, the first fastening near the tip of the tape base 413 is applied. In many cases, a larger force is applied to the wearing portion 411 than the second fastening portion 412. Therefore, as described above, the fastening strength of the first fastening portion 411 with respect to the fastened portion 26 is made larger than the fastening strength of the second fastening portion 412 with respect to the fastened portion 26, thereby securing the fastening. Unintentional peeling of the tape 41 can be suppressed.

  The difference in the fastening strength of the first fastening part 411 and the second fastening part 412 with respect to the fastened part 26 is, for example, making the area of the first fastening part 411 larger than the area of the second fastening part 412. Or a hook member having a larger fastening strength per unit area with respect to the secured portion 26 than the second secured portion 412 may be used as the first secured portion 411. May be.

The tape base 413 may be temporarily fixed from the inner region 416 to the inner surface 422 of the common base 42. Alternatively, when the common base portion 42 is not provided in the connection portion 4 and the fastening tape 41 is directly joined to the main body portion 2, the second fastening portion 412 may be temporarily fastened on the side sheet 3.

  In the disposable diaper according to the second embodiment, when each fastening tape 41 is folded by the third folding line 433 in the state before use, the first fastening part 411 and the second fastening part 412 The exposed portion 4123 may be temporarily fixed to the inner region 416 of the tape base 413 or may be temporarily fixed from the inner region 416 of the tape base 413 to the inner surface 422 of the common base 42. Alternatively, when the common base portion 42 is not provided in the connection portion 4 and the fastening tape 41 is directly joined to the main body portion 2, the second fastening portion 412 may be temporarily fastened on the side sheet 3.

  In the disposable diaper 1 according to the first embodiment, in the state before use, each fastening tape 41 is inward in the left-right direction at a first fold line 431 located in the inner region 416 as shown in FIG. It may be folded back (ie, on the main body 2 side) and folded outward in the left-right direction at the second folding line 432 located in the intermediate region 415 so as to be Z-shaped on the outer surface 423 of the common base 42. The outer surface 418 of the tape base portion 413 and the outer surface 423 of the common base portion 42 are opposed to each other by the folding at the first folding line 431 (or the regions on both sides of the first folding line 431 are opposed to the outer surface 418 of the tape base portion 413). The two areas facing each other are temporarily fixed by a hot melt adhesive layer 44. In addition, due to the folding at the second folding line 432, the regions on both sides of the second folding line 432 on the inner surface 414 of the tape base 413 face each other. The second fastening part 412 is temporarily fastened to the intermediate region 415 on the inner side in the left-right direction with respect to the first folding line 431, and at least a part of the first fastening part 411 is in the lateral direction with respect to the first folding line 431. It is located outside.

  In each fastening tape 41 of the disposable diaper according to the above embodiment, a fine hook structure may be directly formed on the inner surface 414 of the tape base 413 to form the first fastening part 411 and the second fastening part 412. In the main body 2, a fine loop structure may be directly formed on the outer surface of the front portion 201 to form the secured portion 26.

  In each fastening tape 41, for example, marks indicating the positions of the first fastening portion 411 and the second fastening portion 412 are printed on the outer surface of the tape base 413, so that the first fastening is made from the outer surface of the tape base 413. The positions of the part 411 and the second fastening part 412 may be visible.

  In each connection portion 4, the common base portion 42 is not necessarily provided, and the end portions of the respective tape base portions 413 of the two fastening tapes 41 may be directly joined to the main body portion 2. Moreover, each connection part 4 may have only one fastening tape 41. The width of each fastening tape 41 may be constant over substantially the entire length of the tape base 413 in the left-right direction, for example.

  In the disposable diaper 1 according to the first embodiment, the first folded line 431 is not necessarily the inner region if the length of the fastening tape 41 protruding in the left-right direction can be sufficiently shortened in the state before use. It is not necessary to be provided near the edge of the main body portion 2 side of 416 or overlapping the edge. Moreover, in the disposable diaper which concerns on 2nd Embodiment, if the protrusion length to the left-right direction of the fastening tape 41 can fully be shortened in the state before use, the 1st folding line 431a is not necessarily 1st. It is not necessary to be provided in the vicinity of the outer edge 4121 of the two fastening portions 412 or overlapping the outer edge 4121.

  In the disposable diaper according to the above-described embodiment, the tip of the tape base 413 is not necessarily the first folded if the operator can easily grasp the tip of the tape base 413 in the state shown in FIGS. 4 and 9.
