DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an absorbent article, and more particularly to an absorbent article suitable for use in combination with a disposable diaper, a diaper cover, incontinence pants, underwear and the like.

[0002]

2. Description of the Related Art Generally, absorbent articles such as disposable urine pads and sanitary napkins which can be attached to and detached from disposable diapers, diaper covers, incontinence pants, underwear, etc. are composed of a liquid-permeable top sheet and a liquid-impermeable backing. An absorbent body made of cotton-like pulp, high-absorbent polymer, hydrophilic sheet, etc. is arranged between the sheet and these two sheets, and urine and blood are absorbed by the absorbent body through the top sheet. Is done. Among the above products, especially incontinence products are frequently used as necessities not only for infants but also for the sick or incontinent elderly people. There is a need for products that are easier to use, cheaper and less burdensome for caregivers as well as for themselves.

In general, severely incontinent persons such as the sick or elderly use a diaper or a diaper cover in combination with a urine pad, a flat absorbent article or the like. By using an absorbent article used in combination with a diaper or a diaper cover (hereinafter referred to as a combined absorbent article), especially in the case of urinary incontinence, only a small combined absorbent article is used. Since it is only necessary to change the diaper, it is possible to reduce the work load on the caregiver when changing the diaper, and also to the cared person,
The mental burden is reduced. Furthermore, since it is only necessary to replace the inexpensive and small combined-type absorbent article, it is more economical than when the used diaper is replaced every time, and the amount of garbage discharged is small.

[0004] However, there are the following problems regarding the use of the conventional combined absorbent article. That is, when the amount of urination at one time is small or minute, even if the combined absorbent article is only partially contaminated and the water absorption capacity is sufficiently left, it is necessary to replace the whole. That's what it means. In particular, the elderly tend to have less urine volume at one time and tend to excrete more frequently, and in the case of overflowing incontinence, which is said to be more frequent incontinence symptoms in the elderly, a small amount of urine may overflow. Therefore, the combined absorbent article worn is often only partially soiled.

[0005] In addition, when used for elderly people with bent hips or cared persons with injuries or paralysis in one half, the wearer is very likely to be in a lateral position, so that incontinence is caused in that state. Then, in the combined-type absorbent article, it is necessary to replace the absorbent article in spite of the fact that only the part corresponding to the lower part of the body in the lateral position of the wearer is partially soiled. This is not only economical, but also increases the amount of waste and wastes resources.

[0006] Further, when a small combined absorbent article is provided only in a portion where it is predicted that the absorbent article is contaminated by urination in advance, it is expected that the absorbent article will get wet due to a displacement of the absorbent article during or during wearing. There is a problem that it is difficult to be appropriately arranged in a place, and it is easy to leak out. In addition, when the absorbent articles to be arranged are reduced in size, the absorbing capacity is reduced, so that there is a problem that the urine leaks out when urination is more than expected. In this case, it is necessary to change the diaper after use, or leakage to clothes or sheets, bleeding, etc., so there is no point in using the combined type absorbent article, and it takes time for caregivers only. It is also very economically burdensome.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the conventional combination-type absorbent article and to utilize the water absorbing ability of the remaining portion after removing the portion wetted by urination. The object of the present invention is to provide a combined absorbent article capable of performing the above-mentioned.

[0008]

According to the present invention, there are provided a liquid-permeable top sheet, a liquid-impermeable back sheet, and a plurality of absorbent segments each comprising an absorber disposed between the two sheets. In the absorbent article, the top sheet and the back sheet located between the adjacent absorbent segments are formed with means for individually separating the absorbent segments, and the back sheet includes An absorbent article characterized in that a detachable attaching means is arranged at least on a part of a side edge of the absorbent segment.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION In the absorbent article of the present invention, a plurality of absorbent segments are arranged in parallel, and a means for separating each of the absorbent segments is formed. Absorbent articles of the present invention having such a configuration, especially when used as an absorbent article used in combination with a diaper by disposing it on a diaper top sheet, the urination of the wearer may be small or If the absorbent surface of the absorbent article is only partially soiled due to the urinating posture being in the lateral position, etc., only the soiled absorbent segment part is separated and discarded, so that the available absorption is still available. The sex segment can be effectively used.

[0010] Furthermore, since detachable attaching means is disposed on at least a part of the side edge of the absorbent segment, the attaching means joins the absorbent segments to form a large absorbent article. It can be used, even if urination is larger than expected, it can prevent urine from leaking out, and because it can secure a wide absorption area by adding to the part where leakage is uneasy, Leakage can be prevented. Further, this attaching means can be used as a means for fixing the absorbent article on the diaper by using the present absorbent article, and it is possible to prevent the absorbent article from slipping out of the urine when worn or worn.

More specifically, it may be polypropylene, polyethylene, polyester, or a composite fiber composed of two or more components such as polyester, polypropylene, and polyethylene. In particular, low melting point polyester / polyester, polyester / polyethylene, polypropylene /
Polyethylene composite fibers are preferred from the viewpoint of strength, but are not particularly limited.

Absorbent The absorbent used in the present invention is mainly composed of cottony pulp and a superabsorbent polymer which is a superabsorbent material, and may be entirely wrapped with a hydrophilic sheet.
Further, 3 to 60% by weight of a heat-fusible substance may be mixed with the cotton-like pulp and thermocompression-bonded. The configuration of the absorber is not particularly limited, and may be, for example, a single layer mainly composed of cotton-like pulp, or a layered material obtained by uniformly mixing a highly absorbent polymer with cotton-like pulp, or A configuration in which a uniform layer made of a superabsorbent polymer is interposed between two layers mainly composed of cotton-like pulp may be used. The cotton-like pulp is a chemical pulp sheet or a mechanical pulp sheet obtained by defibrating with a crusher and having a fiber length of 5 mm or less. The pulp raw material is not limited to softwoods, but hardwoods, straws, bamboos and kefna are also applicable. The amount of pulp used depends on the target absorber.
For example, used alone, or used by laminating a plurality, or different depending on whether to use another absorbent material, etc., in general,
It is adjusted to 50 to 400 g / m ² .

The superabsorbent polymers include starch-based polymers,
Cellulose type and synthetic polymer type are exemplified.
That is, a saponified starch-acrylic acid (salt) graft copolymer, a saponified starch-ethyl acrylate graft copolymer, a saponified starch-methyl methacrylate graft copolymer, and a saponified starch-acrylonitrile graft copolymer Product, saponified product of starch-acrylamide graft copolymer, saponified product of starch-acrylonitrile 2-acrylamide-2-methylpropanesulfonic acid graft copolymer, acrylic acid (salt) polymer, poly (acrylic acid) A crosslinked product of ethylene oxide, sodium carboxymethyl cellulose, a crosslinked product of a polyvinyl alcohol-maleic anhydride reactant and the like can be used. Among them, those which absorb urine, body fluid, and water at least 20 times their own weight, and polyacrylic Sodium acid-based ones from the point of absorption performance It is also suitable. The distribution amount of the superabsorbent polymer is 10 to 50% of the total weight of the floc pulp in a dry state.
0%, preferably 15-300%, and when such amount of superabsorbent polymer is substantially evenly distributed in the fluffy pulp, when the superabsorbent polymer absorbs and swells, the particles will Mutual interference is kept to a minimum, and there is little formation of a permeation barrier due to continuous contact, and urine and bodily fluid are transmitted and absorbed in three-dimensional directions.

[0015] The heat-fusible substance is preferably a fibrous substance in consideration of mixing with the cotton-like pulp. Examples of the heat-fusible substance include polypropylene, polyethylene, polyester, polyvinylidene, acrylic resin, and nylon resin. Alternatively, a composite fiber composed of two or more components such as polyester, polypropylene, and polyethylene may be used. Particularly, a composite fiber of polyester / polyester, polyester / polyethylene, and polypropylene / polyethylene is preferable from the viewpoint of strength. A fiber diameter of about 1 to 5 denier is preferable, and a fiber length of 3 to 30 mm is suitable for mixing with the cotton-like pulp, but is not particularly limited. By mixing these with the cotton-like pulp layer and thermocompression bonding at a certain pressure or more, a skeletal structure made of a heat-fusible substance is formed, and it is possible to have the strength of the cotton-like pulp layer itself even when wet. Become. The method of thermocompression bonding is not particularly limited, such as a hot press roll, a hot air dryer, a microwave heater, an infrared heater, etc., but heat is uniformly transmitted to the mat layer, and the heat-fusible substance melts to form a skeletal structure. What is necessary is just to be able to form.

The hydrophilic sheet may be any hydrophilic sheet such as a tissue, an absorbent paper, a hydrophilic nonwoven fabric, or the like. As a method of compressing the absorber, the surface of the absorber may be a continuous surface shape such as a roll having a smooth peripheral surface so that the density of the absorber is substantially uniform over the entire surface, or the peripheral surface may be uneven. The density of the absorber may be partially different depending on the roll or the like, and the embossment may have a pattern arrangement for guiding urine or bodily fluid in the vertical direction and the oblique direction. In the case of embossing, the compression section and the non-compression section may be continuous or discontinuous.

Backsheet The backsheet used in the present invention comprises a thin, liquid-impermeable plastic film web or sheet. The plastic can be formed from materials such as, for example, polyethylene, polypropylene, polyvinyl chloride, or similar materials, and polyvinyl alcohol-based film webs or sheets. The backsheet material can be transparent or opaque and can have an embossed surface. It can also be made from a nonwoven fibrous web made to be substantially liquid impermeable.

The backsheet and topsheet of the present invention are provided with means for individually separating each absorbent segment. As a means for separating, a method of forming a perforated cut line on the back sheet and the top sheet, attaching a tearing thread or a tear tape, forming a cut line at the end, and the like are possible, but are not particularly limited. It is not something to be done. Also, the shape of each absorbent segment is not particularly limited, and can be formed in a shape such as a rectangle, a triangle, and a part of a gourd shape, and the absorbent segments having different shapes and sizes may be combined. .

At least a portion of the backsheet at the side edge of each absorbent segment is provided with a mounting means that can be attached to and detached from each absorbent segment and from a used diaper. As the detachable attachment means, an adhesive layer capable of adhering to the top sheet surface of the absorbent segment and the disposable diaper, or a hook material of a hook-and-loop fastener capable of engaging with the top sheet surface can be used. What is necessary is just to arrange on a back sheet.

The absorbent article of the present invention can be advantageously used as a combined absorbent article such as a urine pad used in combination with a disposable diaper or a flat absorbent article. The absorbent article can be used alone or in combination with other members as a feathered type or featherless type sanitary napkin or the like. Although the dimensions of the absorbent article of the present invention vary depending on the type and use of the light incontinence pad, urine pad, flat type absorbent body, etc., in general, the length is 100 mm to 650 mm,
The width is about 40 mm to 350 mm.
