In this embodiment, the non-elastic region 43 of the front waist region 11 overlaps the entire arrangement region of the absorbent core 52 and a part of the end flap, and the non-elastic region 43 of the rear waist region 12 is absorbent. It overlaps the entire arrangement area of the core 52.

≪Each display element≫
Referring to FIGS. 1, 3, and 4, as described above, the front and rear waist sheets 16, 17 have the display element 60. The display element 60 includes an upper display element (first display element) 61 located in the first elastic region 41, a side display element (fourth display element) 62 located in the second elastic region 42, and an inelastic region 43. And a central display element (second display element) 63 located at the center. 4 shows only the configuration of the front waist region 11, the rear waist region 12 has the same configuration.

  Referring to FIGS. 3 and 4 (a), the upper display element 61 and the central display element 63 are different from each other in the state where the front and rear waist sheets 16, 17 are extended. Referring to FIG. 4B, the upper display element 61 and the central display element 63 have the same form in the state where the front and rear waist regions 11 and 12 are contracted. Here, “the state in which the front and rear waist regions 11 and 12 are contracted” is a state before the diaper 10 is worn, and the front and rear waist regions 11 and 11 are formed by the elastic material constituting the diaper 10 without external force being applied. 12 is a contracted state. In addition, “the form is the same” includes the case where the shape is the same or has a minute difference to the extent that the identity is maintained. For example, the vertical direction of one display element 60 such as a similar pattern This means that the ratio between the Y dimension and the horizontal X dimension is substantially the same as the ratio between the vertical Y dimension and the horizontal X dimension of the other display element 60. The vertical dimension and / or the horizontal dimension are different from each other. In the present embodiment, the display element 60 is a diamond mark. However, the display element 60 is not limited to this form. For example, various known elements such as a heart mark, a clover mark, a star shape, and a circular shape are available. Various forms can be used.

  Referring to FIG. 5 (a), conventionally, in the case where the first and second elastic regions 141, 142 and the non-elastic region 143 are formed by a series of elastic waist sheets in each waist region, In addition, in a diaper in which the display elements having the same form are attached to the entire waist sheet, as shown in FIG. 5B, the upper display element 161 located in the first elastic region 141 in a state where the front and rear waist regions are contracted. And the central display element 163 located in the inelastic region 143 are different from each other. In such a diaper, the form of the upper display element 161 collapses and becomes a distorted form as compared with the central display element 163, so that the design property is lowered and the user's willingness to use is lowered.

  Referring to FIG. 4A, in the diaper 10 of the present embodiment, the front and rear waist sheets 16 and 17 are horizontally extended from the upper display element 61 located in the first elastic region 41 in a state of extending in the horizontal direction X. The dimension in the direction X is larger than the dimension in the lateral direction X of the central display element 63 located in the inelastic region 43. Referring to FIG. 4B, in the state where the front and rear waist regions 11 and 12 are contracted, the size of the upper display element 61 in the lateral direction X is reduced, and the upper display element 61 and the central display element 63 have the same configuration. It becomes. In the diaper 10, the display elements 61 and 63 having a sense of unity are positioned in the first elastic region 41 and the non-elastic region 43, so that the design property is high. In the present embodiment, since the upper display element 61 and the central display element 63 have substantially the same shape and size, the similar patterns having different dimensions in the vertical direction Y and the horizontal direction X of the display elements 61 and 63. Compared to, it can give a more unified impression. In the contracted state of the front and rear waist regions 11 and 12, the dimension D1 in the lateral direction X at the edge on the crotch region 13 side is larger than the dimension D2 in the lateral direction X on the edge on the waist opening 22 side. Yes.

  In the extended state of the front and rear waist sheets 16 and 17, the side part display element 62 located in the second elastic region 42 has the same form as the center part display element 63. It becomes. On the other hand, in the state in which the front and rear waist regions 11 and 12 are contracted, the dimension in the lateral direction X of the side display element 62 is reduced, and the side display element 62 and the center display element 63 are different from each other. In the diaper 10, in the contracted state, the side display elements 62 having different forms are located on both sides of the center display element 63, so that the design of the center display element 63 is remarkably high in design. Further, in the contracted state, the side display element 62 and the center display element 63 have substantially the same dimension in the vertical direction Y, and only the dimension in the horizontal direction X of the side display element 62 is small. The center display element 63 has a larger pattern than the side display elements 62, and the effect of making the center display element 63 stand out is high. Moreover, in the expansion | extension state of the front-and-back waist sheets 16 and 17, since the form of the side part display element 62 and the center part display element 63 is the same, in the manufacturing process of the diaper 10, The crotch panel 15 can be easily aligned with the sheet member.

  As described above, in the present embodiment, the display elements 61, 62, 63 are printed on the stretchable sheets 31, 32. In the manufacturing process, since the stretchable sheets 31 and 32 are joined to the non-stretchable sheets 33 and 34 in an extended state, when the display element 60 is printed on the stretchable sheets 31 and 32, Compared with what is printed, a printing area can be made small and material cost can be reduced.

  1 and 3, the crotch panel 15 includes a crotch display element (third display element) 64 that is visible from the outside. The crotch display element 64 is printed in at least one of the leak-proof sheet 53 and the outer sheet 54 constituting the crotch panel 15 and in an inelastic region where no elastic material is disposed. In the state where the front and rear waist regions 11 and 12 are contracted, the crotch display element 64, the center display element 63, and the upper display element 61 arranged in the vertical direction Y have the same form. Since the diaper 10 has the display elements 61, 63, 64 in the front and rear waist regions 11, 12, and the crotch region 13, the design of the diaper 10 as a whole is enhanced, and the display elements 61, 63, 64 are unified. Because it is a design with a high design quality. Moreover, the crotch display element 64 can give a deep impression by being located in the arrangement | positioning area | region of the thick absorbent core 52. FIG.

  Referring to FIG. 2 and FIG. 3, the dimensions L1 and L2 in the longitudinal direction Y of the inelastic region 43 are different from each other in the front waist region 11 and the rear waist region 12. In the present embodiment, the dimension Y3 in the longitudinal direction Y of the absorbent core 52 disposed in the front waist region 11 is smaller than the dimension L4 in the longitudinal direction Y of the absorbent core 52 disposed in the rear waist region 12. Accordingly, the dimension L1 in the longitudinal direction Y of the inelastic region 43 in the front waist region 11 is smaller than the dimension L2 in the longitudinal direction Y of the inelastic region 43 in the rear waist region 12. When the upper display element 61 and the central display element 63 are attached to both the front and rear waist regions 11 and 12, the uniform pattern in the external view of the diaper 10 when the front and rear waist regions 11 and 12 are contracted. While the design property is improved by the arrangement of the diaper 10, it is difficult to distinguish the front and rear of the diaper 10. When the diaper 10 is worn by changing the longitudinal dimension Y of the absorbent core 52 and the non-elastic region 43 between the front and rear waist regions 11 and 12 as in the present embodiment, the inner view or front and rear of the diaper 10 In the state where the waist regions 11 and 12 are extended, the front and rear can be easily distinguished, and the diaper 10 having both excellent design and distinguishability can be obtained.

  FIG. 6 is a diagram illustrating an example of a manufacturing method of the diaper 10 and illustrates a part of the manufacturing process of the diaper 10. In the first process 91 of the manufacturing process, a stretchable first continuous sheet 71 that becomes a base material of the front waist sheet 16 and a stretchable second continuous that becomes a base material of the rear waist sheet 17 by a conveyance roller (not shown). The sheet 72 is continuously conveyed in a state where the sheet 72 is stretched in the machine direction MD at a predetermined stretching magnification (the stretching magnification is N), and is transferred to one surface of the first and second continuous sheets 71 and 72. The crotch panel 15 is intermittently arranged in the machine direction MD. The first and second continuous sheets 71 and 72 are a continuous elastic sheet 75 that is a base material of the elastic sheets 31 and 32 and a continuous non-elastic sheet 76 that is a base material of the non-elastic sheets 33 and 34, respectively. Including. Both ends of the crotch panel 15 are respectively joined to the first and second continuous sheets 71 and 72 via joining means such as a hot melt adhesive to form a composite panel serving as a base material for the diaper 10. .

  In the second step 92, after the composite panel is folded in two so that the crotch panel 15 is on the inside, sealing processing is performed between the adjacent crotch panels 15, and the cross direction CD (direction perpendicular to the machine direction MD) is applied. ) Is formed. In the third step 93, the composite panel is cut along the cutting line 74 extending in the cross direction CD between the pair of joint portions 73, and the individual diapers 10 are formed.

  FIGS. 7A to 7C are views showing the state of the display element 60 printed on the stretchable sheets 31 and 32 in the manufacturing process of the diaper 10, and FIG. , 32 shows a non-elongated state (a state in which the continuous stretchable sheet 75 is relaxed without being applied with an external force; hereinafter referred to as a first state), and FIG. FIG. 7C shows a state in which the continuous elastic sheet 75 is extended in one step 91 (hereinafter referred to as a second state), and FIG. 7C shows a state in which the elastic sheets 31 and 32 are contracted in the manufactured diaper 10 ( A state in which the front and rear waist regions 11 and 12 are contracted, hereinafter referred to as a third state).

  Referring to FIG. 7A, in the continuous stretchable sheet 75 in the first state, the dimension W3 in the lateral direction X of the upper display element 61 is larger than the dimension W4 in the lateral direction X of the central display element 63. Yes. Referring to FIG. 7B, in the second state, the continuous stretchable sheet 75 is stretched at a predetermined stretch ratio (N times), and the dimensions of the display elements 61 and 63 in the lateral direction X are compared to the non-stretched state. As a result, the dimensions become large (approximately N times the dimensions W3 and W4). In this state, the crotch panel 15 is joined to the arrangement area of the central display element 63. Referring to FIG. 7C, in the third state in which the stretchable sheets 31 and 32 are joined and contracted with the non-stretchable sheets 33 and 34, the dimension W2 in the lateral direction X of the central display element 63 is the second. The dimension W1 in the horizontal direction X of the upper display element 61 is smaller than the dimension in the second state and is substantially equal to the dimension W2 of the central display element 63. Yes.

  Although the dimension W1 in the lateral direction X of the upper display element 61 in the third state approaches the dimension W3 in the lateral direction X in the first state, in the third state, the stretchable sheets 31 and 32 are non-stretchable sheets and side seams. 21. In addition to the fact that the shrinkage is suppressed by being joined at 21, various setting conditions such as the sheet properties of the stretchable sheets 31 and 32 and the non-stretchable sheet, the joining mode of both sheets, and the expansion ratio of the stretchable sheets 31 and 32. By this, it will be in the state extended slightly compared with the 1st state. Therefore, the dimension W1 in the third state of the upper display element 61 is 1 to 20% larger than the dimension W3 in the first state. On the other hand, since the dimension in the lateral direction X of the central display element 63 is approximately equal in the second state and the third state, the dimension W2 in the third state is approximately N times the dimension W4 in the first state. Become. In addition, the dimension of the lateral direction X of the side part display element 62 becomes substantially equal to the dimension of the lateral direction X of the center part display element 63 in the first state and the second state, and contracts by the side seam 21 in the third state. This is slightly larger than the dimension in the lateral direction X in the first state. Further, in each state, the dimensions in the vertical direction Y of the upper display element 61, the side display element 62, and the central display element 63 are substantially equal.

In addition, since the basic structure of the diaper 10 of 2nd Embodiment is the same as that based on 1st Embodiment, only a different point is demonstrated below.

  Referring to FIG. 8A, in the continuous non-stretchable sheet 76 in the fourth state, the dimension W5 in the lateral direction X of the upper display element 61 is larger than the dimension W6 in the lateral direction X of the central display element 63. ing. Referring to FIG. 8B, in the fifth state, the dimension in the horizontal direction X of each display element 61, 63 is substantially equal to that in the fourth state. In this state, the crotch panel 15 is joined to the arrangement area of the central display element 63. Referring to FIG. 8C, in the sixth state, due to the contraction of the elastic sheets 31, 32, the dimension W1 in the lateral direction X of the upper display element 61 is smaller than the dimension in the second state. It is substantially equal to the dimension W2 of the central display element 63.

  The dimension W1 in the horizontal direction X of the upper display element 61 in the sixth state is a value close to 1 / N times the dimension W5 in the fourth state. More specifically, due to the influence of the side seam 21, the dimension W1 is slightly larger than 1 / N times the dimension W5. The dimension W1 in the lateral direction X of the central display element 63 in the sixth state is a value close to the dimension W6 in the lateral direction X in the fourth state, but is a stage before the first step 91, When the inelastic region 43 is formed in the second continuous sheets 71 and 72, the region that becomes the inelastic region 43 is slightly shrunk by heat embossing, so the dimension W2 of the sixth state of the central display element 63 Is 1 to 20% smaller than the dimension W6 in the fourth state. Therefore, the center display element 63 may be printed so that the size of the pattern is larger than the state of the diaper 10 (sixth state) in the material state (fourth state) before manufacturing.

  In the diaper 10 of the present embodiment, the display element 60 is printed on the non-stretchable sheets 33 and 34, and the display element 60 does not expand and contract during the manufacturing process. In addition, when the display element 60 is printed on the continuous elastic sheet 75 that becomes the elastic sheets 31 and 32, the printing is stretched in the diaper 10 and the display becomes thin, but the non-elastic sheet 33, By printing on 34, such a situation can be eliminated and the symbol can be clearly displayed, and the symbol having a complicated design can be selected.

  The configurations shown in the first and second embodiments can be used in combination with each other. For example, in one of the front and rear waist regions 11 and 12, the display element 60 is printed on an elastic sheet, and the other In the waist region, the display element 60 may be printed on the non-stretchable sheet. In the second embodiment, the inelastic region 43 may be formed by not arranging the stretchable sheets 31 and 32.

<Modification>
FIG. 9A is a diagram similar to FIG. 4A in an example of a modification, and FIG. 9B is a diagram similar to FIG. 4B in an example of a modification.

  In the present modification, the side display element 62 located in the second elastic region 42 is different from the center display element 63 in the stretched state of the front and rear waist sheets 16 and 17, and the front and rear waist regions 11 are different from each other. , 12 are contracted, the side display element 62 and the central display element 63 have the same form. The side display element 62 has the same form as the upper display element 61 in the extended state of the front and rear waist sheets 16 and 17. In such a diaper 10, the display elements 61, 62, 63 having the same form are positioned in the first elastic region 41, the second elastic region 42, and the non-elastic region 43, so that the entire front and rear waist regions 11, 12 have a sense of unity. Can give an impression.

  FIG. 10A is a view similar to FIG. 4 in another modification of the diaper 10. In this modification, a face mark is displayed as the display element 60. In the state where the front and rear waist sheets 16 and 17 are extended, the upper display element 61 is a distorted mark extending in the lateral direction X. However, in the state where the front and rear waist regions 11 and 12 are contracted, the upper display element 61 is displayed. The central display element 63 has the same form, has a substantially circular outer shape, and is a beautiful mark with a balanced face (balanced). In addition, the side part display element 62 becomes a form shrink | contracted to the horizontal direction X in the contracted state of the front-back waist areas 11 and 12, and a form is different from the center part display element 63. FIG.

  FIG. 10B is a view similar to FIG. 4 in still another modification of the diaper 10. In the present modification, the upper display element 61 and the central display element 63 are in the same form and have similar patterns with different sizes when the front and rear waist regions 11 and 12 are contracted. Thus, even if the display elements have different sizes, having the same form can give a unified impression.

  In each embodiment and each modified example described above, the display element 60 printed on the stretchable sheets 31, 32 or the non-stretchable sheets 33, 34 is a continuous stretchable sheet 75 (stretchable) in the manufacturing process (first process 91). In consideration of at least the expansion ratio of the continuous elastic sheet 75 in the manufacturing process among the expansion ratio of the adhesive sheets 31 and 32), the contraction rate by the heat embossing, and the suppression of contraction by the side seam 21, at least the upper display element 61 And the central display element 63 are set so as to have the same form in the state where the front and rear waist regions 11 and 12 are contracted. In addition, since the diaper 10 is manufactured through the manufacturing process mentioned above, the identity of the form in each display element 61-64 may contain the manufacture error. When a plurality of upper display elements 61 and central display elements 63 are formed, it is sufficient that at least one upper display element 61 and central display element 63 are set to have the same form.
