[Industrial applications]

 The present invention relates to an absorbent product in the form of pants, commonly referred to as a tapeless absorbent product, which comprises a body having a waist hole and two leg holes.

[0002]

[Prior art]

 Absorbent products in the form of pants, commonly referred to as taper-shaped absorbent products, having a body with a waist hole and two leg holes have become widely used for applications such as diapers and sanitary products. Is coming. Conventional tapeless absorbent products are made by bending a sheet material with a absorbent sheet sandwiched between a liquid impermeable back sheet and a liquid permeable top sheet into a U-shape and partially It has a structure in which a waist hole and two leg holes are formed by being combined.

An important advantage of such a tapeless absorbent product is that it can be worn with a feeling similar to that of normal underwear, and that it adheres well to the body in the worn state.

In order to maximize these benefits, it is important to choose a size that fits the wearer snugly. When the absorbent product of appropriate size is worn, even if the amount of excrement exceeding the absorbent capacity of the absorbent is excreted at one time, it does not leak, and the intended purpose as an absorbent product is achieved. .

[Problems to be solved by the device]

 However, the sheet-shaped material that constitutes the conventional tapeless absorbent product has poor stretchability due to the above-mentioned structure, and therefore, it is easy to put on and take off when trying to set the optimum size for the wearer. It causes the contradiction that it disappears. In addition, wearers who need such absorbent products often need help from their mothers if they are infants or carers if they are large, which makes them difficult to put on and take off. It becomes a serious defect.

Further, in a usual tapeless absorbent product, in a worn state, particularly when the user bends down, a force larger than the contracting force that acts laterally along the waist hole edge acts downward, which causes It may cause slipping. In order to prevent such an inconvenience, it is proposed to arrange an elastic body in this portion, but not only the structure becomes complicated, but also slippage cannot be surely prevented.

The object of the present invention is to eliminate the above-mentioned deficiencies of conventional tapeless type absorbent products, to obtain a good fit in a worn state, and to attach and detach them extremely easily. At the same time, it is an object of the present invention to provide a taper type absorbent product which can surely prevent slipping during wearing.

[0008]

[Means for Solving the Problems]

 According to the present invention, there is provided a main body having a waist hole and two leg holes, the front body part and the back body part of the main body being connected to each other through side bands made of elastic sheets. And a notch is formed in the elastic sheet to provide a tapeless absorbent product.

That is, in the tapeless absorbent product of the present invention, the sheet-shaped material composed of the top sheet, the back sheet, and the absorbent material located between the top sheet, the back sheet, and the absorbent material on both sides of the front and back portions of the product. , Are connected via a side band made of an elastic sheet.

Therefore, when worn, an excellent fit is obtained due to the contracting force of the sidebands, and at the time of putting on and taking off, the sidebands greatly extend to enlarge the waist hole and the leg holes, so that putting on and taking off is extremely easy. It can be carried out.

Moreover, the sideband can behave differently depending on the direction of the expansion / contraction stress line acting on the waistband side and the leghole side, so that the sideband bends or rises. Even if you repeat, you will not slip.

In the present invention, as an example of an elastic sheet suitable for forming a side band, a nonwoven fabric is laminated on one or both surfaces of a sheet-like elastic body made of a material such as synthetic rubber, and these are parallel to each other. It is a linear joint that is joined by means such as thermocompression bonding. The elastic sheet is highly stretchable in the direction orthogonal to the lengthwise direction of the linear connecting portion, and the non-woven fabric having a soft feel is located on the surface of the elastic sheet. Moreover, since the side band is formed with a notch, the waist hole peripheral portion and the leg hole peripheral portion can be greatly extended in the direction away from each other. This extension is extremely effective in maintaining the leak-preventing effect as well as improving the feeling of wearing because the peripheral edge of the leg hole is kept in close contact with the legs even if the waist is pulled up excessively. .

The shape of the notch formed in the side band may be a slit extending in the front-rear direction, or may be an ellipse or a rhombus having an appropriate area. This notch helps the vertical extension of the side band as described above, and also acts as a ventilation hole, further improving the usability.

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

【Example】

 FIG. 1 is a perspective view showing an example of a tapeless absorbent product constructed according to the present invention. The absorbent product shown in FIG. 1 comprises a liquid-permeable top sheet, a liquid-impermeable back sheet, and a main body 11 composed of a sheet material composed of an absorbent body sandwiched between the two. There is. As shown in FIG. 2 when developed, the main body 11 has a substantially rectangular shape, and an arc-shaped recess 12 is formed at the center of each of the opposite long sides, and the short sides are mutually When folded in two so as to face each other, a crotch region 11A located between the recesses 12 and 12 and a front portion 12B and a rear portion 12C located on both sides thereof are formed. .

Further, substantially rectangular elastic sheets 13A, 13A 'and 13B, 13B' are connected to the main body 11 so as to be continuous on both sides of the front viewing portion 12B and the back viewing portion 12C, respectively. The elastic sheets 13A and 13A 'are joined to the front ends of the elastic sheets 13B and 13B' facing each other to form a connecting portion 14. As a result, the front part 11B and the rear part 11C of the main body part 11 are composed of a side band 13 composed of elastic sheets 13A and 13B and a side band 13 'composed of elastic sheets 13A' and 13B 'on both sides. Are connected to each other, thereby forming a tapeless absorbent product having a waist hole 15 and two leg holes 16.

As shown in FIG. 3, the elastic sheet used to form the side band in the example of FIG. 1 is made of synthetic rubber, polyurethane, styrene-butadiene block polymer, polyolefin elastomer, or the like by thermocompression bonding or the like. The sheet-like elastic body 31 made of a material that can be bonded with the sheet-like elastic body 31 is laminated on one side or both sides (both sides in the illustrated example) of the sheet-like elastic bodies 31 and 33, which are excellent in touch to the skin. They have a structure in which they are connected by means of thermocompression bonding or the like by linear connecting portions 34 arranged in parallel with each other. Preferably, the sheet-like elastic body 31 is provided between the adjacent connecting portions 34, 34. A channel-shaped space 35 is formed between the non-woven fabric and the non-woven fabrics 32 and 33.

Further, the side bands 13 and 13 ′ located on both sides are linearly crossed across the coupling portion 14 so as to reach from the position close to the front viewing portion 11 B to the position close to the rear viewing portion 11 C. A slit-shaped notch 17 that extends is formed. The vertical position of the notch 17 is preferably selected so as to be slightly closer to the leg hole 16 than the central portion thereof.
