Abstract
The invention provides a disposable wearing article having a structure capable of reducing the coating amount (amount of use) of an adhesive and suppressing occurrence of defective products. In addition, the invention provides a manufacturing apparatus and a manufacturing method for easily and inexpensively producing such a disposable wearing article. In the case of a waist gather rubber (30), the adhesive is applied to the outer back sheet and the inner back sheet (1, 2) only in tension areas (TA1, TA2), and a free area (FA) in a relaxed state is formed in a non-adhered state with the back sheet (1, 2). When the wearing article is worn, wrinkles are formed substantially only by the contraction of the tension areas (TA1, TA2) of the wrinkles (30). The free area (FA) in the slack state and the non-adhered state is cut in two at the intermediate position. Each of the cut pieces (301, 301) is integrally connected to an adjoining tension area (TA1, TA2) in a tensioned state and in an adhered state.
Description
Technical field
The present invention relates to a kind of disposable wearing article, the manufacture device of described disposable wearing article and manufacture method,
In described disposable wearing article, one or more elongated elastomers are arranged on the single sheet material with flexibility
(sheet) one side side or between there is a pair sheet material of flexibility.Specifically, such as, at disposable diaper, physiology with defending
In the disposable wearing article (these are also body fluids absorbent article) of raw towel etc., the present invention is best suited for waistline wrinkle pleat (that is, shape
Become the fold of waist portion, pleat or folding line) forming part, it addition, the present invention is applicable to such disposable wearing article
Manufacture.
Background technology
Such as in disposable diaper (either pants type, banding pattern), (each sheet material is by single or multiple lift structure for multiple sheet materials
Become) cover the absorber containing superabsorbent polymer granule.Generally, (there is also itself packaged sheet material than absorber
Situation about covering) closer to the side of health, the top-sheet (also referred to as surficial sheets, upper layer of sheet material) etc. of liquid permeability is set,
And in the side contrary with health, liquid-impermeable back sheet material (also referred to as inner face sheet material, outer layer sheet) etc. is set.It addition,
In the waist of backsheet, leg, waist portion etc., configuration the elastomer (such as, thread rubber) of elongate, these are elastic
Body is relevant with the formation of waist wrinkle pleat (gather), leg wrinkle pleat, waistline wrinkle pleat etc. when elastic return (that is, shrinking), and
There is the function making disposable diaper and body fit when dressing.Additionally, due to the outside of back sheet material (that is, with health
The face of opposite side) it is positioned at the outermost of disposable diaper, therefore there is the situation possessing marking part, described marking part is for straight
Connect printing marking class (house mark, brand mark, font mark etc.), product data (title, specification, manufacturer, sale
Business etc.), explanation hurdle (using method, points for attention etc.) etc., or for adhesive label.
In such disposable diaper, when waistline wrinkle pleat is formed at the whole of waist portion because of the contraction of waistline elastomer
During body (all-round), improve the wearing of health (that is, waistline).But, the contractility (that is, elastic restoring force) of waistline elastomer
Also affecting absorber and marking part via backsheet, absorbability reduces because of the deformation of absorber or movement, or identification because of
The bending of marking part and be deteriorated.
Then, such as in patent documentation 1, will be to extended state part and unstretched condition part (with absorber and mark
Show that the allocation position in portion is corresponding) entirety of the elastomer that carried out tension adjustment is bonding with back sheet material, and thus, setting will not
Form the region of wrinkle pleat, thus prevent the absorbability of absorber and the identification of marking part from reducing.But, in patent documentation 1,
Owing to adhesive applicating is in sheet material side, back, therefore there is following trend: have to be coated with the width more than elastomer,
And thus increase the coating amount (that is, usage amount) of bonding agent.It is additionally, since and is also coated to be formed with the pleat that wrinkles unrelated non-stretching shape
Polymorphic segment (back sheet material corresponding thereto), therefore, increasingly increases the coating amount of bonding agent.
On the other hand, such as in patent documentation 2,3, bonding agent is coated in intermittently sheet material side, back, and bonding whole
Body is in the elastomer of extended state, cuts off the non-bonded part of the elastomer fitted afterwards, thus, it is ensured that the absorption of absorber
Property and marking part identification while, reduce bonding agent coating amount.But, in patent documentation 2,3 (because of certain reason,
In the fabrication process), in the case of the non-bonded part of elastomer produces cut-out error, because of the contraction (elastic return) of elastomer
Back sheet material be integrally formed waistline wrinkle pleat, thus this disposable diaper is by as defective products.It addition, at patent documentation 2,3
In, even if in the case of bonding agent is coated in intermittently elastic side, being also identical.
