Further, the end edge (rear end edge) on the other end 60B side of the non-fixed portion 64 is easily rolled up. The other end 60B of the belt member 60 is an end edge (front end edge) of the other end side of the non-fixed portion 64. Since the first adhesive portion 71 extends across the other end 60B of the belt member 60, the winding of the other end side of the non-fixed portion 64 can be suppressed.

The adhesive portion 70 may have a second adhesive portion 72. The second adhesive portion extends in the first direction between the first adhesive portions. The second adhesive portion is disposed on the other end side of the belt member 60. The second adhesive portion 72 is overlapped with the belt member 60 in the front direction L in the first direction. The second adhesive portion 72 of the present embodiment extends toward the front side of the belt member 60. The second adhesive portion 72 may be one or more columns. By the second adhesive portion 72, the other end 60B side of the belt member can be fixed to the wearing article, and the end edge of the non-fixed portion 64 on the other end 60B side can be protected. Therefore, it is possible to suppress the end edge of the other end side of the non-fixed portion 64 from being rolled up.

Further, the belt member 60 may be protected in a state before being worn. Specifically, at least a part of the release sheet 75 may be disposed in a region overlapping the belt member 60 in the thickness direction T. It is preferable that the release sheet 75 is overlapped with the non-fixed portion in the thickness direction. The peeling sheet 75 covers the other end 60B of the belt member 60, that is, the front end edge. The length of the peeling sheet 75 in the width direction W is longer than the length of the belt member 60 in the width direction W. The belt member 60 is protected by the release sheet over the full width range, and the belt member 60 can be prevented from being accidentally broken or bent before the absorbent article is used. Further, in another aspect, at least a part of the packaging sheet may be disposed in a region overlapping the belt member 60 in the thickness direction T.

Next, an absorbent article according to another embodiment will be described. In the following description, the same portions as those of the above-described embodiments are denoted by the same reference numerals, and their description will be omitted. Fig. 5 is a plan view of the absorbent article 10A of Modification 1 as viewed from the non-skin opposing side.

In the absorbent article 10A of Modification 1, one end 60A of the belt member is the front end edge of the belt member, and the other end 60B of the belt member is the rear end edge of the belt member.

The first adhesive portion 71 can span the one end 60A of the belt member 60 in the first direction. The first adhesive portion 71 can extend toward the outer side of the belt member 60 in the first direction D1 from the one end 60A of the belt member 60. One end 60A of the belt member 60 is an end edge (rear end edge) of one end side of the fixing portion. Since the first adhesive portion 71 extends over the one end 60A of the belt member 60, the end edge of the one end side of the fixing portion 62 can be protected, and the occurrence of the loss of the peeling of the fixing portion 62 can be suppressed.

The adhesive portion 70 may have a third adhesive portion 73. The third adhesive portion 73 extends in the first direction between the first adhesive portions 71. The third adhesive portion is disposed on one end side of the belt member. The third adhesive portion 73 is overlapped with the belt member 60 in the front direction L in the first direction. The third adhesive portion 73 of the present embodiment extends toward the front side of the belt member 60. The third adhesive portion 73 may be one or more columns. By the third adhesive portion 73, the one end 60A side of the belt member can be fixed to the wearing article, and the end edge of the fixing portion 62 on the one end 60A side can be protected. Therefore, it is possible to suppress the occurrence of a situation in which the fixing portion 62 is peeled off accidentally.

As another aspect, the temporary fixing portion 66 (see FIG. 6) may be provided in the non-fixed portion 64 of the belt member 60. The temporary fixing portion 66 is detachably joined to the back sheet 22 of the non-skin opposing surface of the main body portion 20. By providing the temporary fixing portion 66, when the belt member 60 is used (when manufactured, when worn), it is possible to suppress the non-fixed portion 64 from being rolled up or the non-fixed portion 64 from being bent.

The joining force of the temporary fixing portion 66 is lower than the joining force of the fixing portion 62. Since the joining force of the temporary fixing portion 66 is lower than the joining force of the fixing portion 62, when the user uses the belt member 60, the temporary fixing portion 66 is easily peeled off, and the belt member 60 can be operated by grasping the non-fixing portion 64. Examples of the fixing means of the temporary fixing portion 66 include an adhesive, embossing, heat welding, ultrasonic welding, etc., and the amount of application (area, basis weight) of the adhesive can be reduced compared with the fixing portion 62, or The pressing of the embossing process is weakened compared to the fixing portion 62. Further, the temporary fixing portion 66 may be formed by embossing of the outer edge of the body portion.

The joining force can be measured by a pull tester (Instron Japan Company Limited; model 5543). For example, the bonding force is measured in the following manner. First, the test piece of the tape member and the test piece of the back sheet were fixed to the upper fixing portion and the lower fixing portion of the drawing tester. The width of the test piece fixed to the upper fixing portion and the lower fixing portion was set to 10 mm. A fixing surface corresponding to the fixing portion 62 is formed between the test piece fixed to the upper fixing portion and the test piece fixed to the lower fixing portion. The relative displacement speed of the upper fixing portion and the lower fixing portion of the drawing tester was set to 100 mm/min, and the maximum load point during the period in which the joint portion was peeled off was used as the joining force (adequate strength).

Fig. 6 shows a belt member of the absorbent article according to Modification 2 and Modification 3, and shows an example of the temporary fixing portion 66. Fig. 6(a) is a plan view of a belt member 60D according to a second modification, and Fig. 6(b) is a belt member 60E according to a third modification. The belt member 60D and the belt member 60E are provided with a coating region coated with an adhesive. The coating region has a first coating region R1 provided in the fixing portion 62 and a second coating region R2 provided in the temporary fixing portion 66 of the non-fixing portion 64. The area ratio of the second coating region R2 (the ratio of the area of the coating region per unit area) is lower than the area ratio of the first coating region R1. The basis weight of the adhesive in the second coating region R2 is lower than the basis weight of the adhesive in the first coating region R1. It is preferable that the basis weight of the second coating region R2 is low and the area ratio of the first coating region is low. The length of the first coating region R1 in the width direction is longer than the length of the second coating region R2 in the width direction. The length of the second coating region R2 in the width direction is shorter as it goes away from the first coating region R1. That is, the amount of the adhesive applied to the application region is reduced from the one end 60A side of the belt member 60D toward the other end 60B side of the belt member 60. The second application region R2 may include a region in which the adhesive is applied as a plaque, as shown in FIG. 6(b), and a region in which the adhesive is applied in a dot shape.

According to such a configuration, the joining force of the fixing portion 62 can be made smaller than the joining force of the temporary fixing portion 66. Further, in the process in which the adhesive is applied, the nozzle or the like which sprays the adhesive is brought into contact with the belt member, and the adhesive which is ejected from the nozzle can be adjusted. Specifically, the adhesive is sprayed toward the region where the fixing portion 62 is provided, and the injection of the adhesive is stopped in the region of the end of the fixing portion 62. The agent is then viscous, and even if the ejection is stopped, the amount of ejection does not immediately become zero but the amount of ejection gradually decreases. The temporary fixing portion 66 can be configured by the adhesive which is gradually reduced in the amount of ejection. In such a temporary fixing portion 66, the engaging force gradually becomes smaller as it goes away from the fixing portion 62. The end edge of the temporary fixing portion 66 on the other end 60B side (the end edge on the non-fixing portion 64 side) may also reach the other end 60B of the belt member 60D. Further, the temporary fixing portion 66 may be provided in conjunction with the first adhesive portion 71 of the present invention, or may be provided instead of the first adhesive portion 71 of the present invention.

Further, all the contents of Japanese Patent Application No. 2017-252410, filed on Dec. 27, 2017, are hereby incorporated by reference.
