Problems solved by technology

[0007] However, the existing methods only improve the peelability by lowering the joint strength as a whole, but have not achieved both the strength of the joint and the peelability

Deformed example 1

[0085] Such as Figure 7As shown, in the above-mentioned embodiment, the strength-reducing region T may be provided on the upper end (end around the waist opening W side) and the lower end (end around the leg opening L side) of the joining parts 21, 22. ), the non-strength-reduced region S is provided in the middle part of the region extending from the waist opening W to the leg opening L on the joining parts 21 and 22 .

[0086] According to Modification 1, since the strength-reduced region T is provided on the upper and lower ends of the joining parts 21 , 22 , it can be easily broken when a force is applied to the upper and lower ends.

Deformed example 2

[0088] Such as Figure 8A , 8B As shown, in the above embodiment, the strength-reduced regions T and non-strength-reduced regions S may be alternately and continuously provided along the longitudinal direction of the joining portions 21 and 22 , that is, the strength-reduced regions T are intermittently provided.

[0089] At this time, the respective areas of the strength-reduced region T and the non-strength-reduced region S can be appropriately changed. Therefore, it can be as Figure 8A As shown, the strength-reduced regions T and the non-strength-reduced regions S are alternately and continuously provided in the same shape (same length), and it is also possible to Figure 8B The settings shown are one side larger than the other.

[0090] According to Modification 2, it is possible to appropriately adjust the local bonding strength of the bonding portions 21 and 22 .

Deformed example 3

[0092] Such as Figure 9A , 9B As shown, in the above-mentioned embodiment, the first strength weakening portion T1 and the second strength weakening portion T2 juxtaposed along the width direction of the joint portion 21, 22 can be used to form the strength reduction region T, and the joint portion 21, 22 Either one of the first strength-weakening portion T1 and the second strength-weakening portion T2 is provided continuously from the upper end portion to the lower end portion.

[0093] That is, for example it can be done as Figure 9A As shown, the non-strength-reducing region S is provided on the upper and lower parts of the first strength-reducing part T1, and the second strength-reducing part T2 is continuously provided from the upper end to the lower end of the joint parts 21, 22. Figure 9B As shown, non-strength-reduced regions S are provided above and below the second strength-reduced portion T2, and the first strength-reduced portion T1 is provided continuously fr...

Abstract

An absorptive article (1) comprises: an absorptive body (10) which includes an absorption body (13); and an exterior body (20) which is provided to the outer surface side of the absorptive body (10) and is provided with a belly-side portion (F) which is located on the belly side of a human body when the absorptive article(1) is worn and with a back-side portion (B) which is located on the back side of the human body when worn, wherein a waist opening section (W) and a pair of left and right leg opening sections (L) are formed in the absorptive article (1) by joining, using heat sealing or ultrasonic sealing, the belly-side portion (F) and the back-side portion (B) of the exterior body (20) together at joint sections (21, 22) located at both side ends of the belly-side portion (F) and the back-side portion (B). Reduced strength regions (T) and unreduced strength regions (S) are disposed between the belly-side section (F) and the back-side section (B) at the positions of the joint sections (21, 22). A reduced strength region (T) has disposed therein a joint strength-reducing material for reducing the joint strength between the joint sections (21, 22), and an unreduced strength region (S) has no joint strength-reducing material disposed therein. Enhanced strength and increased easiness of peeling of the joint sections are achieved at the same time.

Description

technical field [0001] The present invention relates to absorbent articles. Background technique [0002] Conventionally, a disposable paper diaper is known as one type of absorbent article. As disposable paper diapers, underpants type and tape type paper diapers are known. [0003] Among them, pants-type paper diapers generally include: an absorbent main body including an absorber, and an outer cover sheet integrally provided on the outer surface side of the absorbent main body. They are joined at joints at both side ends to form a waist opening and a pair of left and right leg openings. [0004] Such an underpants-type disposable diaper is preferably such that the joint portion is not accidentally torn off when worn, and is easily torn off and separated when discarded. [0005] Therefore, for example, a technique has been proposed in which bonding strength is weakened by applying an adhesive between the sheets stacked on both side ends of the exterior sheet, and based o...
