Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to disposable pants for use in infants, adults and incontinent persons and a method for producing the same.

[0002]

2. Description of the Related Art In a conventional disposable diaper, as disclosed in Japanese Patent Application Laid-Open No. 57-77304, a pair of left and right side flaps are joined and fixed to each other to form a pair of left and right side flaps. A so-called pants-type disposable pants in which a leg opening and a waist opening are respectively formed has been proposed. The pants-type disposable pants (hereinafter, referred to as “disposable pants”) are configured such that a leg opening and a waist opening are formed to be extendable and contractable, respectively, so as to fit a wearer's body shape. Such disposable pants can usually be worn by the wearer in a standing position, for toilet training to promote the infant's "diaper separation", or for incontinent persons or walking adults. It is useful for use.

[0003] On the other hand, some proposals have also been made on a method of manufacturing disposable pants. They are basically disclosed in JP-A-57-77304 and JP-A-1-28210.
No. 2, as seen in the longitudinal direction of the absorber,
It is represented by a so-called "cross-flow" manufacturing method in which the web flow direction is vertical. Generally, the gathers in disposable pants are for following the movement of the wearer, and the gathers should be soft and fit to prevent leakage of excrement and not hurt the wearer. As means for preventing the wearer from being injured, various proposals have conventionally been made, such as using a low-modulus elastic member, providing a plurality of elastic members with a wide width, and disposing a cushion material between the gather and the skin. .

[0004]

However, in the waist gather of the disposable pants, the elastic member extending between the top sheet and the back sheet contracts, and the top sheet and the back sheet are folded. The waist gathers are arranged over the entire circumference of the waist opening, but rarely excrement may leak out of the pants through the gaps of the folds of the top sheet. On the other hand, if the excreted liquid is kept in the gap between the folds of the top sheet even if it does not leak out, this has caused eczema and rash on the wearer.

If the elongation of the gathers is increased to prevent such excretion from leaking, the wearer may be injured, and the sheet is made thinner so as to reduce the gap between the folds. Then, there is an inconvenience that the touch becomes worse. Therefore, an object of the present invention is to provide a disposable pants that prevents leakage of excrement from the waist opening and does not hold the excrement in the waist opening and a method of manufacturing the same.

[0006]

SUMMARY OF THE INVENTION The present invention comprises a body having a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorber disposed between the two sheets. When worn, the abdomen is positioned on the abdomen of the wearer and the back is positioned on the back, and the abdomen and the back are joined and fixed at both side edges. In a pants-type disposable pants in which an opening and a pair of leg openings are formed, a waist elastic member is arranged over the entire periphery of the opening adjacent to the waist opening, and inside the waist opening. The above object has been attained by providing a disposable underpants characterized in that a three-dimensional elastic cuff is extended from below the waist elastic member toward the crotch part.

The present invention also relates to a method of manufacturing disposable pants having a three-dimensional elastic cuff at a peripheral portion inside a waist opening. An absorber arranging step of arranging the absorber so as to be perpendicular to the back sheet flow direction, and a waist elastic member arrangement of symmetrically and continuously arranging the waist elastic member on both side edges along the back sheet flow direction A step of forming a product web by continuously joining a three-dimensional cuff adjacent to the waist elastic member, a step of superimposing the top sheet on the back sheet so as to cover the absorber, When,
Folding the web in two at the flow direction centerline,
The above object has been achieved by providing a method for producing disposable pants, comprising a cutting step of sealing and cutting the web between the absorbers.

[0008]

The three-dimensional cuff is elastically contractible and falls down toward the leg opening of the disposable pants. The three-dimensional cuff is elasticized in a peripheral portion inside the waist opening, and effectively fits the wearer's skin. The three-dimensional cuffs form a pocket between the body and the waist opening, accommodate the excrement floating in the disposable pants without being absorbed by the absorber, and absorb the part that can be absorbed by the absorber, By blocking the portion that cannot be absorbed, it is prevented from reaching the waist opening.

In addition, a silicone-based oil agent is provided on the peripheral portion of the top sheet 2,
A method of applying a hydrophobic compound such as paraffin wax, or a method of applying a hydrophilic compound such as an alkyl phosphate ester in advance and performing a water-repellent treatment by a method of washing the periphery with warm water. Leakage can be prevented.

The back sheet 3 is made by adding a filler to a thermoplastic resin such as polyolefin, and is stretched. The back sheet 3 is a moisture-permeable liquid-impermeable sheet that allows vapor to permeate, or a sheet having a feeling similar to underwear, such as a film. A composite material of a nonwoven fabric or a composite material of a film and a woven fabric is used. The absorbent 4 is preferably made of fibrillated pulp as a main material and a high-molecular-weight water-absorbing polymer in combination.
A mixture obtained by heat-treating a mixture of cellulose fibers and a high-molecular-weight water-absorbing polymer, and more preferably a mixture generally referred to as a polymer sheet, is preferred. The high-molecular water-absorbing polymer has a holding performance capable of absorbing and holding a liquid 20 times or more its own weight, and is preferably in the form of particles having a gelling property. Examples of such a high-molecular water-absorbing polymer include starch. -Acrylic acid (salt) graft polymer, saponified starch-acrylonitrile copolymer, crosslinked sodium carboxymethyl cellulose, acrylic acid (salt) polymer and the like are preferable.

The elastic members 8A, 8B, 10A,
As B, 11A and 11B, any known in the art, such as thread rubber, flat rubber, film-type rubber, stretchable nonwoven fabric or foamed polyurethane, can be used. Good. Also, the stress at the time of 150% elongation of one elastic member is 30 to 10
The weight is preferably 0 g, and it is more preferable to use a plurality of low-stress elastic members so that no trace is formed on the abdomen.

Next, a preferred embodiment for manufacturing the disposable pants according to the present invention will be described with reference to FIG. In the following forming steps, the steps of forming the side elastic members 10A and 10B and the leg elastic members 11A and 11B will be omitted in order to clarify the essence of the present invention. The web of the backsheet 3 is fed out by the unwinding device, while the absorber web is cut into individual absorbers 4 by the cutter 50 and is intermittently arranged on the backsheet web 3. The long side of the absorber 4 is
It is arranged perpendicularly to the flow direction of the web (absorber arrangement step).

Further, the top sheet 2 having a width capable of substantially covering the absorber 4 is drawn out from above, and
The product is superimposed on the backsheet 3 and the absorber 4 by the roll 51 to form a product web (superposition process). Next, the process proceeds to the step of forming the three-dimensional cuffs 20A and 20B. In this embodiment, the three-dimensional cuffs 20A and 20B are formed by a part of the back sheet 3. That is, the cuff elastic members 2 are provided at both edge portions in parallel with the flow direction of the main web.
3 and the edge portions of both ends of the back sheet 3 are folded in such a manner as to surround the cuff elastic member 23 (cuff formation).

In this embodiment, the cuff elastic member 23 is continuously stretched on the edge of the back sheet 3 to form the three-dimensional cuff 20.
A, 20B, but without being bound by the above,
Three-dimensional cuff 20A, 20 with cuff elastic member 23 arranged
A method of continuously joining and fixing a sheet piece in which B is formed separately to the back sheet 3 may be used. Next, in the waist gather forming step, the waist elastic members 8A and 8B are arranged on both side edges in parallel with the web flow direction (waist elastic member arranging step), and both side edges of the back sheet 3 are folded again. . The cuff elastic member 23 and the waist elastic members 8A and 8B are wrapped around the back sheet 3 in this manner.

When all the materials have been assembled, the leg opening 14 is punched out in a punching step 52. The punching in the process section 52 is performed by a rotary die cutter or the like. Then, in the folding process section 53, the center line 51 in the flow direction of the main web is provided.
, The web is side-sealed in the side sealing step section 54, and then cut into individual disposable pants in the cutting step section 55 (cutting step) and finally accumulated.

Thus, the disposable pants 1 according to the embodiment of the present invention are manufactured, and continuous three-dimensional cuffs 20A and 20B are formed on the disposable pants 1. According to such a manufacturing method, it is possible to reduce the number of webs and steps of the three-dimensional cuffs 20A and 20B, which contributes to space saving of a processing machine. Furthermore, according to the manufacturing method of the present embodiment, by utilizing the folding of the back web (top sheet or back sheet), the arrangement accuracy of the three-dimensional cuffs can be improved, and the space for the processing machine equipment can be reduced.

It goes without saying that the embodiments of the disposable pants according to the present invention and the method of the present invention can be arbitrarily modified without departing from the spirit of the present invention. For example, a configuration in which a tearing guide means is arranged adjacent to the side seal portion of the disposable pants 1 so as to be easily peeled off from the wearer may be adopted. The tear guide means may be a cut guide line, a seal portion, or a material that can be easily torn, but it is necessary that the tear guide means has a strength that does not break or tear during wear. .

In the production of the disposable pants according to the present invention, the three-dimensional cuff may be formed separately from the web, and the waist elastic member may be arranged on the web and then joined to the web. The three-dimensional cuff need not use a cuff elastic member as long as the sheet member 24 itself has elasticity.

[0028]

According to the disposable pants of the present invention, the excrement is prevented from leaking from the waist opening, and the waste liquid is not retained in the waist opening. According to the method for producing disposable pants of the present invention, the above-mentioned disposable pants can be suitably produced.

According to the disposable pants of the present invention,
It is possible to eliminate bleeding leakage from the waist due to formation of a gap due to gathering, and to provide an inexpensive product having an excellent flap texture. Further, excrement can be prevented by the three-dimensional cuff.
