Abstract

(57) [Summary] [Purpose] Let the infant sense that the infant has excreted while wearing disposable training pants. A wet holding sheet 11 is provided on the inner surface of the pants as a wetness detecting means.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to disposable training pants. More specifically, the present invention relates to so-called training pants that allow an infant to wear in order to quickly habituate the infant from a diaper wearing habit to a diaper-free life.

[0002]

[Prior Art]

 Generally, conventional training pants are made of cloth and can be washed and repeatedly used. When a child excretes while wearing pants, the excretory liquid easily leaks from the pants. Therefore, it has the effect of giving discomfort to the infant and notifying the mother of the excretion.

[0003]

[Problems to be solved by the device]

 However, the training pants need not only be washed, but also excretory liquid easily leaks from the pants, so that the floor of indoor tatami mats, carpets, etc. is soiled.

[0004] The present invention configures pants in which excrement does not leak unlike conventional cloth-made pants, and nevertheless, for making infants feel that the pants are wet with excretion, The issue is whether it should be configured as described above.

[0005]

[Means for Solving the Problems]

 This invention for solving the above-mentioned problems is directed to a pair of a body opening having a liquid-absorbent core interposed between a liquid-permeable inner surface sheet and a liquid-impermeable outer surface sheet, to which a stretchable elastic member is attached, and a pair of body openings. We assume disposable training pants with leg openings.

In this invention, the wetness sensing means is provided in at least the central region of the inner sheet. The above-mentioned wetness sensing means is composed of the inner sheet portion in the central region and the wetness holding sheet laminated on the upper surface of the inner sheet portion. The moisture retaining sheet is made of a flexible sponge material.

In a preferred embodiment, a plurality of apertures are formed in the wet holding sheet at intervals, and if necessary, the outer peripheral edge of the wet holding sheet is pressure-fused to the inner surface sheet. Seal it.

[0008]

[Action]

 According to the training pants of the present invention having the above-mentioned configuration, the excreted liquid in the wet holding sheet flows in the plane direction of the wet holding sheet and permeates in the thickness direction thereof, but is located on the lower surface of the wet holding sheet. It is temporarily blocked from permeating through the inner sheet of the pants and being absorbed by the core located inside the pants, and stays in the moisture retaining sheet. That is, the moisturizing retention sheet cooperates with the inner sheet of the pants to perform a tank function of temporarily retaining the excreted liquid. Therefore, the infant feels the wetness from the wetness holding sheet.

An embodiment of the training pants according to the present invention will be described below with reference to the drawings.

1 to 3, the pants 1 has a body opening 2 and a pair of leg openings 3. The pants 1 is composed of a liquid-permeable inner sheet 4, a liquid-impermeable outer sheet 5, and a sheet- or mat-shaped liquid-absorbent core 6 interposed therebetween. Expansion / contraction elastic members 7 and 8 are attached between the inner and outer surface sheets 4 and 5 forming the trunk opening 2 and the leg opening 3 respectively while being stretched with an adhesive. The pants 1 are vertically folded so that the inner sheet 4 is located on the inner surface in the center of the pants 1 in the unfolded state shown in FIG. 2, and the opposite side portions 9 except the leg openings 3 are intermittently folded. It is fusion bonded.

The inner surface sheet 4 is a longitudinal and transverse stretchable nonwoven fabric of ²⁰ to 35 g / m ² which is mainly composed of thermoplastic and hydrophobic crimped fibers and has a sheet-like shape obtained by a fluid entanglement method. The outer surface sheet over DOO 5 is made of a material of plastic type, or a rubber-based nonwoven fabric and an inner surface of. 20 to 35 g / m ² in vertical and horizontal stretch and liquid permeability are formed from the same material as the inner sheet 4 and the vertical transverse stretch Film (not shown) is integrally joined. Instead of this, a non-woven fabric which is stretchable in the longitudinal and transverse directions and impermeable to liquid or resistant to liquid may be used. The core 6 is formed by molding a mixture of fluff pulp, thermoplastic and hydrophobic crimped fibers, and superabsorbent polymer powder into a sheet or mat shape, and coating it with a water-absorbent tissue paper 10.

A wetness holding sheet 11 is laminated in the central area of the inner sheet 4. The wet retention sheet 11 is made of a spongy material having a thickness of 0.5 to 5 mm, such as urethane-based or cellulose-based material having flexibility, and has apertures 12 of 0.5 to 10 mm formed at appropriate intervals. A hydrophilic fiber layer (preferably non-woven fabric) 13 of 10 to 30 g / m ² is adhered to each other. The permeability of the excreted liquid is lower in the inner sheet 4 than in the wet holding sheet 11. Therefore, the excreted liquid impregnated or absorbed in the wet holding sheet 11 is temporarily blocked from permeating the inner surface sheet 4 and being absorbed by the core 6, and stays in the wet holding sheet 11. More specifically, the excreted liquid stays on the sponge-like wet holding sheet 11 in the space between the fiber layer 13 and the inner sheet 4. That is, the wet holding sheet 11 cooperates with the inner surface sheet 4 to perform a tank function of temporarily holding the excreted liquid. Therefore, the infant senses the wetness from the wetness holding sheet 11. The excreted liquid accumulated in the wetness holding sheet 11 permeates the inner sheet 4 and is absorbed by the core 6 as time passes, especially when it becomes saturated. In addition, when the infant's body pressure is applied, it easily exudes to the surface, but in this case as well, the infant senses wetness.

When the wet holding sheet 11 has the openings 12, excess excreted liquid is immediately absorbed by the core 6 from the openings 12 through the inner sheet 4 and the surface of the wet holding sheet 11. Overflow can be avoided, and if the fiber layer 13 is provided, the appearance is good and the cloth feels like a cloth. However, even if the fiber layer 13 is not provided, the intended purpose of the present invention can be achieved. And having it is not an essential requirement. In order to impart a cloth-like feel to the wetness holding sheet 11, it is possible to use the spongy material in which hydrophilic fiber groups are planted.

The holding of the wet holding sheet 11 in the laminated state with respect to the inner surface sheet 4 is performed by bonding the wet holding sheet to the inner surface sheet 4 with an adhesive pattern 14 applied in a stripe shape in the length direction thereof. Further, the pattern may extend in the width direction of the wet holding sheet 11 or may be in the form of dots arranged at appropriate intervals.

As shown in FIGS. 5 and 6, when the outer peripheral edge 15 of the wet holding sheet 11 is fused to the inner surface sheet 4 under heat and pressure, the outer peripheral edge 15 is crushed and the seal line is removed. Since it is formed, it is effective in preventing the excreted liquid absorbed by the wet holding sheet 11 inside the seal line from crossing the seal line to the outside. For this reason, the excreted liquid in the wet retention sheet 11 flows outward and becomes difficult to leak from the crotch side edge of the pants 1.

[0016]

[Effect of the device]

 According to the training pants according to the present invention, when the infant excretes while wearing the pants, the moisturizing and retaining sheet on the inner sheet wets and comes into contact with the infant's skin. Therefore, this moisturizing sheet gives the infant an unpleasant feeling, senses that the infant has excreted by himself, and makes a habit of notifying others of the excretion while using the pants.

On the other hand, since the training pants according to the present invention can prevent the excretion liquid from leaking through the core and the outer sheet, the leakage liquid does not pollute the floor surface and the like, and the wet holding sheet Can be sufficiently moistened to enhance the effect of sensing wetness, and can exert excellent functions as training pants.

Since the outer peripheral edge of the wet retention sheet is sealed to the inner sheet by pressure fusion, the excreted liquid in the wet retention sheet is prevented from flowing beyond the outer peripheral edge to the outside. can do.
