JPH045961A - Disposable training underpants - Google Patents

Abstract

PURPOSE:To constitute the training underpants so that a wetting sensing area gives a sense of discomfort to a baby, the baby senses his excretion by himself, and he gets into the habit of informing the excretion to others, while he is using the underpants by providing the wetting sensing area having a hydrophilic property in at least a part of the inside surface sheet of the training underpants. CONSTITUTION:Underpants 1 have a flexible body opening part 2, and a pair of flexible leg opening parts 3. The underpants 1 are constituted of liquid permeable inside surface sheet 4, a non-liquid permeable outside surface sheet 5, and a sheet or mat-like liquid absorbing core body 6 interposed between them. The inside surface sheet 4 uses thermoplastic roll-shrink fibers as a material, and is constituted of nonwoven cloth of vertical/horizontal flexibility to which a sheet-like form is given by a fluid confounding method. In a necessary part of the inside surface sheet 4, a wetting sensing area 12 whose wetting property by an excreted liquid is improved by processing it with a surface active agent, etc., of a wellknown hydrophilic agent is divided and formed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to disposable training pants. In more detail, we have infants wear diapers in order to quickly change the habit of wearing diapers to a life without diapers.
Regarding so-called training pants.

(Prior art, invention or problem to be solved) Generally,
Conventional training pants are made of cloth and can be washed and used repeatedly.

However, not only do they need to be washed, but when infants defecate while wearing pants, excrement fluid leaks from the pants and stains indoor surfaces such as tatami mats and carpets.

This invention sufficiently fulfills the original function of Toreninta pants, which is that when an infant defecates while wearing pants, the pants become wet with excrement fluid, which makes the infant feel uncomfortable. The challenge is how to construct pants that do not leak excretory fluid.

(Means for Solving the Problems) The pants according to the present invention are based on the premise that the pants, which define an elastic torso opening and a pair of elastic leg openings, are composed of at least an inner sheet and an outer sheet. shall be.

The present invention solves the above problem by providing a hydrophilic moisture sensing region in at least a portion of the inner sheet in the configuration based on the above premise.

In a preferred embodiment, the moisture sensing region is rendered hydrophilic by treating the inner sheet portion with a hydrophilic agent;
Alternatively, it can be applied by forming at least the surface of the sheet portion in that area with a hydrophilic material.

(Operations and Effects) According to the pants according to the present invention, when an infant defecates without wearing the pants, the moisture sensing area of the inner sheet becomes wet and comes into contact with the infant's skin. Therefore, this wetness-sensing area causes discomfort to the infant, and the infant senses when he or she has urinated, and while using the pants, develops the habit of notifying others of the urination.

On the other hand, although the pants according to the present invention are made of training pants, the liquid-impermeable outer sheet prevents excrement from leaking, so there is no possibility of excrement leaking and staining the floor etc. .

In particular, in the pants according to the present invention, the liquid-impermeable outer sheet prevents excretory fluid from leaking from the pants, so the moisturizing effect of the moisture sensing area is increased accordingly, and 1- it fully performs its excellent function as a lening pants. . These features can never be obtained from traditional cloth training pants.

(Example) An example of the pants according to the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, pants 1 have an elastic torso opening 2 and a pair of elastic leg openings 3. Pants L includes a liquid-permeable inner sheet 4 and a liquid-impermeable outer sheet 5.
and a sheet or mat-like liquid absorbent core 6 interposed between them.

An elastic member 9. Attach IO to extension F via adhesive. At the center of the pants 1 in the unfolded state shown in FIG. The pants 1 shown in FIG. 1 are constructed.

The inner sheet 4 is made of thermoplastic crimped fibers and is made of a longitudinally and horizontally stretchable nonwoven fabric that has been given a sheet-like shape by a fluid entanglement method. A predetermined portion of the inner sheet 4 is treated with a known hydrophilic agent (such as a surfactant) to define a moisture sensing region 12 that improves wettability with excretory liquid.

In order to provide the wetness sensing region 12 without performing such a treatment, hydrophilic fibers such as rayon fibers, synthetic fibers that are naturally hydrophobic and made hydrophilic (for example, hydrophilized polyester fibers) may be used alone or in combination. The formed nonwoven fabric or hydrophilic paper (Japanese paper) cut into a given size may be integrally joined to the upper surface of a given part. In addition, the inner sheet 4
The entire wetness sensing area 12 may be used, in which case a nonwoven fabric formed from the hydrophilic fibers alone or, if necessary, a mixture thereof with hydrophobic fibers, may be used. .

The outer sheet 5 is constructed by integrally bonding a horizontally and vertically stretchable and liquid-permeable nonwoven fabric made of the same material as the inner sheet 4 and a synthetic resin or rubber acid film that is vertically and horizontally stretchable. Instead, a nonwoven fabric that is stretchable both in the vertical and horizontal directions and is impermeable to liquid or resistant to liquid permeation may be used.

Since this invention targets training pants, it is not necessarily necessary to use the core body 6. However, when the core body 6 is used as in the illustrated embodiment, the core body 6 removes the excretory fluid that moistened the inner sheet 4 from the inner sheet 4, and as a result, the infant feels a wet feeling. It is not preferable to have a liquid absorbing ability that makes it impossible to feed. This is because it does not provide a sufficient sense of moisture to infants.
