Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a disposable diaper comprising a waterproof layer, a water-absorbing layer, and a water-resistant water-permeable layer, and having a remarkably enhanced water absorbing capacity.

[0002]

[Prior art]

 Conventionally, various types of disposable diapers have been proposed, such as the disposable diaper disclosed in Japanese Utility Model Laid-Open No. 2-149223 proposed by the present applicant. In this conventional diaper, a diaper body having a waterproof layer on the lower surface of the water-absorbing layer and a water-resistant water-permeable layer on the upper surface is folded twice in the longitudinal direction to form a three-layered state. The front end and the rear end are fixed by heat sealing or the like.

[0003] In this disposable diaper, a gap is formed in the central portion along the length direction by the inverted bent portion during use, and this gap is opened to the left and right, applied to a local portion, and mounted.

[0004]

[Problems to be solved by the invention]

 However, the crotch at the base of both feet is narrow, so if the diaper body is worn by applying a diaper body to the crotch area with a gap as in the above-mentioned conventional disposable diaper, the diaper expands to the right and left at the crotch area. , Urine and the like may leak sideways. In addition, since it cannot absorb water sufficiently, it will leak out after urinating several times.

[0005] In consideration of such points, a gather is formed on both sides of the sheet-shaped diaper with rubber, and when applied to a local area, the thigh is tightened with the gather, so that urine or the like seeps outward. However, there is a problem that blood circulation is worsened due to tightening of the thigh, itching and painful, and even if it is simply tightened by gathering, urine will leak laterally if water absorption capacity is low .

Further, the above-mentioned conventional disposable diaper has a structure in which the front end and the rear end of the three-layered state are fixed to prevent leakage, but on the other hand, the front and rear ends are sufficiently left and right. There is also a drawback that urine and dirt cannot be reliably absorbed because they do not spread.

The present invention has been devised in order to solve the above-described problems, and abuts on a local part in a natural form, absorbs a large amount of water such as urine, and ensures that there is no side leakage. The purpose is to.

[0008]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a wide band-shaped diaper having a waterproof layer disposed on the lower surface of a water-absorbing layer and a water-resistant water-permeable layer disposed on an upper surface thereof. Forming a first bent portion by bending the portion upward along the length direction and forming a second bent portion by inverting the first bent portion upward to form a second bent portion; In this configuration, the vicinity of the central portion near the front of the body and the first bent portion overlapping the vicinity of the central portion are partially fixed.

Therefore, the diaper body surely permeates the water-absorbing layer by the water-resistant water-permeable layer that comes into direct contact with the skin, and the water permeated by the water-absorbing layer leaks to the outside by the waterproof layer. Is prevented.

Further, the diaper body forms a first bent portion and a second bent portion by bending twice along the length direction, and the first diaper body is opposed to the center portion near the front portion. First, the front end and the rear end can be fully opened to the left and right because the bends are only partially fixed, so that it becomes a ship bottom type, so to speak, the first bend and the second bend. Since the abdomen or buttocks can be widely covered by the bent portion, reliable absorption of moisture and the like is achieved.

Since the center portion near the front portion and the first bent portion facing the front portion are partially fixed, the portion does not expand left and right and is narrow, and therefore, the portion is narrowed. If you put it on your crotch and put it on, you will not have to worry about side leakage.

[0012]

[Embodiment of the invention]

 Hereinafter, the present invention will be described with reference to the drawings of the embodiments. The wide band-shaped diaper body 1 is configured by arranging a waterproof layer 3 on a lower surface of a water-absorbing layer 2 and a water-resistant water-permeable layer 4 on an upper surface, and integrally joining four outer peripheral edges.

The water-absorbing layer 2 is made of, for example, a plurality of thin water-absorbing sheet materials polymerized, flocculated pulp, or a polymer water-absorbing material, is relatively thick, and absorbs excrement such as urine. You can do it.

The waterproof layer 3 is made of a thin sheet material in which a synthetic resin such as polyethylene is laminated on one side of waterproof paper, plain paper or rayon paper, or a thin sheet material of a synthetic resin such as polyethylene as it is. It has a sufficient waterproofing effect even in contact with urine and the like absorbed by the water absorbing layer 2.

Further, the water-resistant and water-permeable layer 4 is made of a non-woven fabric of rayon or polypropylene, can pass urine and the like, and has sufficient strength even when wet.

The diaper body 1 having the above-described configuration is formed by bending both side end portions upward along the length direction to form first bent portions 6 on both sides of the center portion 5 in an overlapping manner. The second bent portion 7 is formed by folding the bent portion 6 upward and reversely so as to be overlapped on the upper surface of the first bent portion 6 to be in a folded state.

Therefore, in the folded state, the first bent portion 6 overlaps the central portion 5, and the second bent portion 7 overlaps the first bent portion 6, and each of the first bent portions 6 overlaps the first folded portion 6. In the continuous portion where the bent portion 6 and the second bent portion 7 face each other, a gap 8 is formed along the length direction.

Therefore, the central portion 5, the first bent portion 6, and the second bent portion 7 are expanded by opening the gap 8 left and right in the folded state.

Then, the vicinity of the central portion 5 near the front portion of the diaper body 1 and the first bent portion 6 which overlaps in the vicinity of the center portion 5 are partially fixed by providing a fixing portion 9 in a spot shape, for example. Then, only this part is not opened to the left and right, so that the narrow state can be maintained.

FIG. 1 shows a state in which the first bent portion 6 and the second bent portion 7 are expanded with respect to the center portion 5, and the front end portion and the rear end portion are sufficiently expanded. Although the front part can cover the abdomen and the rear part can cover the buttocks, the diaper body 1 does not open left and right at the fastening part 9 near the front part, and its narrow state is maintained. Therefore, it is fitted tightly to the crotch, and there is no danger of lateral leakage of moisture.

The partial fastening of the center portion 5 near the front portion of the diaper body 1 and the first bent portion 6 is the fastening portion 9 in the above embodiment, but is not limited to this. Instead, it may be a line along the width direction or a fastening portion having a certain area.

As described above, the present invention has been described based on the embodiment of the drawings. However, the present invention is not limited to the above-described embodiment, and is not limited to the configuration described in the claims for utility model registration. Can also be implemented.

[0023]

[Effect of the invention]

 In short, according to the disposable diaper of the present invention, not only the part to be applied to the crotch is narrow, but also the part in contact with the buttocks in the wearing state expands like a ship bottom, so it is perfect for the local area. Not only does not cause lateral leakage of water due to close contact with the skin, but also absorbs a large amount of urine, etc., and does not leak even after several urinations. Will not cause. In addition, since the thighs are not tightened and the abdomen and buttocks can be sufficiently spread and covered, a large amount of water and the like can be surely absorbed, thereby exhibiting many excellent practical effects.
