ことを目的とするものである。[Problems to be Solved by the Invention] In order to impart a satisfactory elastic elasticity to the leg opening, waist opening, and part of the waist around a pants-type diaper, the pants-type diaper is used. It is clear that the fixed parts on both sides are released and deployed, and when you look at this, it is clear that the directions of expansion and contraction elasticity do not always coincide with each other, and they intersect each other or have a curved shape, so it is an advanced technology. In addition, the production speed of the manufacturing machine is limited, which may be a hindrance to achieving the purpose of mass-producing at low cost necessary for all used articles. In other words, there is a contradictory relationship between the followability and fit to the wearer and the production efficiency of the product, and raising the quality increases the production cost, and the usability must be sacrificed to produce at low cost. was there. The present invention solves the above-mentioned problems, a leg opening, a waist opening,
It is an object of the present invention to provide a pants-type diaper with stretch elasticity imparted to both sides of the waist and having excellent wearing comfort, and a method for producing the same.

きがある。Further, according to the present invention, both sides of the waist of the diaper have a layered structure in which an elastic layer member sandwiched between an outer layer sheet made of a fibrous sheet and an inner layer sheet made of a fibrous sheet is laminated to form an exterior member. Since both sides around the waist of the diaper are elastic and have good gas permeability, it is possible to quickly diaper even if sweat occurs when the diaper is in close contact with both sides of the waist of the wearer. It keeps the skin dry and prevents rashes by letting it escape to the outside.

Except for the one closer to the side edge of the continuous outer layer sheet 122, all the other elastic elastic members are cut near the middle of the intersecting points, that is, at a position where the absorbent main body 7 is arranged in the subsequent step. To be done. As a result, the stretchable elastic member that has been in the stretched state is relaxed in the stretch and contracts, so that the stretchable stress does not substantially work in the vicinity of the cut portion. To this end, the adhesive for adhering and fixing the stretchable elastic member is intermittently supplied so that the stretchable elastic member is not bonded to the continuous outer layer sheet 122 in a desired region near the cut portion. good.

材が配置されていた方が好ましいのである。In the present invention, the second to fifth stretchable elastic members arranged on the exterior member 8 are cut off at the central portion except those located above the front body 4 of the diaper body 1 using a pants type wear, It is discontinuous. According to the present invention, when the continuous exterior member 105 is continuously manufactured, the second stretchable elastic member, the fourth stretchable elastic member, the third stretchable elastic member, and the fifth stretchable elastic member are used.
Elastic elastic members formed by combining elastic elastic members to form a part of the leg openings by crossing each other with the length of twice the width of the diaper body 1 on the continuous outer layer sheet 122 as a cycle. Since the member also has a function of imparting elastic elasticity around the waist on the next adjacent outer layer sheet, these elastic members are arranged while being cyclically moved on the outer layer sheet in the stretched state. However, it is not preferable that the diaper main body 1 except for the upper part of the front body 4 exists in the vicinity of the crotch part of the central part and the rear body 5 in an extended state because it takes time to widen and it is difficult to wear and the appearance is impaired. However, it is preferable that an elastic elastic member is arranged on the upper portion of the front body 4 over the entire width of the front body 4 in order to improve the adhesion to the abdomen.

Therefore, in order to enhance the effect of preventing leakage, only both side edge portions may be subjected to hydrophobic processing. The back sheet 17 is a liquid-impermeable polyethylene sheet, preferably a polyethylene sheet having micropores, and a moisture-permeable liquid-impermeable sheet obtained by adding a filler to a thermoplastic resin and stretching it. It is more preferable because you do not have to worry about getting stuffy.

めて効率的に製造することができる。The pants-type disposable diaper of the present invention has an excellent wearing feeling because the leg openings, waist openings, and waist sides of the diaper have elastic elasticity. . Stretching elasticity around both legs is given by the action of both the substantially linear stretchable elastic member provided on the absorbent main body and the stretchable elastic member provided on the pant-type exterior member. The elastic elastic member provided to provide the elastic member also has an effect of imparting elastic elasticity around the waist at the same time, but the elastic elastic member in the exterior member has elastic elastic members around the legs and the waist in its manufacturing means. Since they are installed at the same time and continuously, they can be manufactured very efficiently.
