  As shown in FIGS. 4 and 5, when the absorbent article main body 1 is attached to the body by overlapping and engaging the tape-like fastener 14, one tape-like fastener 14, that is, the lower tape-like fastener 14 is attached. In the state where the hook member 17 is engaged with the first loop member of the loop fastener 18 having the largest engagement force, the other tape-shaped fastener 14, that is, the upper tape-shaped fastener is formed so as to intersect the lower tape-shaped fastener 14. In a state where the hook member 17 of the fastener 14 is engaged with the second loop member 19 of the lower tape fastener 14, the hook member 17 of the lower tape fastener 14 and the first loop member of the loop fastener 18 are engaged. When the hook member 17 of the upper tape-shaped fastener 14 is peeled off from the second loop member 19 of the lower tape-shaped fastener 14, the resultant force is strongest, and the hook portion of the lower tape-shaped fastener 14 is removed. 17 is never peeled off from the first loop member of the loop fastener 18.

  When the hook members 17 of the upper and lower tape fasteners 14 are peeled off from the second loop member 19 and the first loop member of the loop fastener 18, respectively, a knob 21 formed on the tip side of the tape fastener 14 is used. Since at least the vicinity of the front end portion on the front surface side and the back surface side is formed in the front surface non-engagement portion 22 and the rear surface side non-engagement portion 23 that cannot be engaged with the hook member 17, the knob portion 21 is provided with the hook member 17. The tape-like fastener 14 can be easily attached and detached.

  Further, since at least the vicinity of the front end portion of the knob portion 21 formed on the front end side of the tape-like fastener 14 is formed in the surface non-engaging portion 22 that cannot be engaged with the hook member 17, the knob portion 21 is on the surface. The surface non-engaging portion 22 on the surface side of the knob portion 21 is not engaged with the hook member 17 even if it is folded back and overlapped with the hook member 17, so that the knob portion 21 is separated from the hook member 17. Does not require any special operation.

  Further, since the area of the hook member 17 is formed wider than the area of the back surface non-engaging portion 23 of the knob 21 formed on the fastening tape 15, the area of the hook member 17 is set to the back surface non-engaging portion 23 of the knob 21. When the absorbent article main body 1 is attached to the body as shown in FIG. 4 or 5 when the absorbent article main body 1 is attached to the body, as shown in FIG.

The hook member 17 of the upper tape-shaped fastener 14 is not engaged with the loop member 19 or the engagement portion has an extremely small area, and the second loop member 19 of the lower tape-shaped fastener 14 is not used. Securely engaged

  Further, since the area of the hook member 17 is formed wider than the area of the surface non-engaging portion 22 of the knob 21 formed on the fastening tape 15, the area of the hook member 17 is set to the surface non-engaging portion 22 of the knob 21. When the absorbent article main body 1 is attached to the body as shown in FIG. 4 or 5 when the absorbent article main body 1 is attached to the body, as shown in FIG. For example, the hook member 17 of the fastener 14 is engaged with the opposite side of the surface non-engagement portion 22 of the knob portion 21 of the lower tape-shaped fastener 14 in a state where the hook member 17 is not engaged with the first loop member of the loop fastener 18. Since the hook member 17 of the upper tape-shaped fastener 14 is not engaged with the lower tape-shaped fastener 14 that is not engaged, the hook member 17 of the upper tape-shaped fastener 14 Peeling or upper Without easily being separated from the second loop members 19 of the lower side of the tape-shaped fastener 14 is pulled-loop shaped fastener 14, both the tape-shaped fastener 14 is securely engaged.

  In addition, since this kind of absorbent article main body 1 is manufactured, a method of continuously manufacturing the absorbent article main body 1 while moving along the longitudinal direction of the absorbent article main body 1 is employed. The length of the absorbent article main body 1 along the longitudinal direction is the same, and accordingly, the area of the hook member 17 is set so that the front surface non-engaging portion 22 and the back surface non-engaging portion 23 of the knob portion 21 formed on the fastening tape 15. For example, as shown in FIG. 6, the width dimension “a” of the hook member 17 in the width direction of the absorbent article main body 1 is set so that the width dimension “b” of the front surface non-engaging portion 22 The engagement portion 23 is formed longer than the length c.

The relationship among the lengths of the width dimension a of the hook member 17, the width dimension b of the front surface non-engaging portion 22 and the width dimension c of the back surface non-engaging portion 23 is as follows.
The width dimension a of the hook member 17> the width dimension b of the front surface non-engagement portion 22> the width dimension c × 2 of the rear surface non-engagement portion 23
By satisfying these width dimension conditions, as shown in FIG. 5, the two tape-like fasteners 14 and 14 located at both side edges of the back waist portion 5 of the absorbent article main body 1 are provided. The hook member 17 is securely attached to the second loop member 19 even when the other tape-like fasteners 14 are engaged with each other in a state where the hook members 17 are engaged with the tip portions facing each other. Can be engaged.

The engaging force with the hook member 17 is
First loop member of loop fastener 18> second loop member 19> third loop member 20
Therefore, when the absorbent article main body 1 is manufactured or not used, the extension portion of the tape-like fastener tape 14 of the absorbent article main body 1 is folded and the hook member 17 has the smallest engaging force. Since the hook member 17 is prevented from being damaged by being engaged with the loop member 20, the third loop member 20 only needs to have an engaging force that can be temporarily fixed in a state in which the fastening tape 15 is folded. There is no shortage of the engaging force for temporarily fixing the folded state.

  Further, since the first loop member of the loop fastener 18 is larger in engagement force with the hook member 17 than the second loop member 19, the tape-like fastener tape 14 is overlapped to engage the hook member 17 as shown in FIGS. When combined, the engagement force between the hook member 17 of the fastening tape 15 of the tape-like fastener tape 14 on the lower side of the one side and the first loop member of the loop fastener 18 is the same as that of the tape-like fastener tape 14 on the other side. The hook member 17 of the fastening tape 15 of the upper tape-like fastener tape 14 is lower than the engaging force between the hook member 17 of the fastening tape 15 and the second loop member 19 of the lower tape-like fastener tape 14. When peeling from the second loop member 19 of the tape-like fastener tape 14 on the side, the fastening tape 15 of the tape-like fastener tape 14 on the lower side is peeled off. Without the engagement of the first loop member click member 17 and loop fastener 18 is released, the operability is improved.

  Further, in the embodiment, as shown in FIG. 2, the knob 21 is integrally formed at the tip of the fastening tape 15 of the tape-like fastener tape 14, but as shown in FIG. It is also possible to adopt a configuration in which the knob 21 is formed by attaching the knob 21a to the tip of the fifteen. The material of the knob member 21a is selected so that the front surface side and the outer surface side of the knob member 21a are formed in the front surface non-engaging portion 22 and the back surface non-engaging portion 23 that cannot be engaged with the hook member 17. Or the surface side and the outer surface side of the knob member 21a are processed.

  Moreover, the hook member 17 can engage / disengage the front surface side and the back surface side of the absorbent article main body 1, for example, the top sheet 2 and the back sheet 3 formed by the liquid-permeable sheet 10 and the gather sheet 11. It can also be formed of a material such as a nonwoven fabric.

  In this configuration, even when the tape-like fastener 14 is disengaged from the first loop member of the loop fastener 18, the hook member 17 of the tape-like fastener 14 can be engaged with an appropriate position of the absorbent article body 1. When disposing of the absorbent article main body 1 after use, the tape-like fastener 14 is engaged with an arbitrary position of the absorbent article main body 1 so that the absorbent article main body 1 is kept in a small state. Can be disposed of.

  In this configuration, the engaging force with the hook member 17 is such that the first loop member of the loop fastener 18> the second loop member 19> the front and back sides of the absorbent article body 1> the third loop member 20. By doing so, it is possible to obtain an engaging force between a state in which the absorbent article body 1 is attached to the body and a state in which the body is discarded when the hook member 17 is engaged with the front and back sides of the absorbent article body 1.

  In the above-described embodiment, the two tape-like fasteners 14 and 14 are arranged in parallel at intervals on the left and right sides of the back waist portion 5 of the absorbent article body 1. Not limited to the configuration in which the two tape-like fasteners 14 and 14 are provided on the left and right sides, an appropriate number of tape-like fasteners 14 and 14 can be disposed on the left and right sides, respectively.
