[Problems to be solved by the invention]
In order to remedy the shortcomings of conventional absorbent articles, the present invention provides an absorbent comprising an outer sheet on the garment side, a surface sheet on the body side, and an absorbent body between the two sheets, and applies tension to the elastic member surrounding the absorbent body. It is attached to the seat in a ring shape and the urine can be prevented from leaking by making the body side inward by restoring the tension of the elastic member. It is easy and lightweight and has the intended purpose.
[0004]
[Means for Solving the Problems]
The present invention provides an absorbent article comprising an outer sheet on the clothing side, a surface sheet on the body side, and an absorbent body between both sheets, and an elastic member surrounding the absorbent body is attached in an annularly tensioned state. It is formed into a dome shape with the body side inward by restoring the tension of the elastic member.
The above absorbent body has a circular or oval planar shape, and the elastic member is attached to the outer sheet or the top sheet in a state of being in an annular tension so as to be in contact with or away from the outer side of the absorbent body. .
The elastic member is attached in an annular shape with tension applied, and the sheet is formed into a dome shape by automatically drawing it into a dome shape using the tension restoring force of the elastic member, thereby preventing urine leakage and shifting from the body. In addition to being difficult and not bulky like conventional absorbent articles, the area covering the skin is small, it is hard to be stuffy, and it is lightweight and can be carried.
[0005]
The present invention also includes an adhesive or other attachment means for attaching the absorbent article to clothing on the outer surface of the outer sheet. This is because the absorbent article is fixed to the underwear when worn and the absorbent article is not easily displaced. Therefore, conventional fastener tapes, belts, and the like are unnecessary and easy to wear, and easy to remove and attach / detach.
[0006]
The adhesive application part is covered with release paper. In the case of fixing to the undergarment, if the release paper is peeled off, the pressure-sensitive adhesive is exposed and fixed to the undergarment to make it difficult to slip.
Further, according to the present invention, the outer sheet on the clothing side is a leak-proof sheet made of polyethylene or the like, and the outer sheet can be improved by laminating a nonwoven fabric excellent in texture and sweat absorption on the outer side of the leak-proof sheet.
In the present invention, the body side surface sheet is a liquid-permeable sheet. Therefore, urine is absorbed by the absorbent through the liquid-permeable sheet.
In addition, the present invention is equipped with a bag having a second annular elastic member extending from between the outer edge of the absorber and the annular elastic member inside the dome shape, thereby preventing leakage at the elastic member in multiple stages, thereby preventing leakage. The effect can be further improved.
[0007]
Furthermore, the present invention provides an adhesive in a state where an absorbent body is placed on a leak-proof sheet in a stretched state, in contact with the outer periphery of the absorbent body, or in a state where a tension is applied to the elastic member in an annular shape along a distance. By attaching the surface sheet on top of each other and releasing the expansion of the leakproof sheet, the attached annular part of the elastic member is automatically squeezed by restoring the tension of the elastic member to form a dome shape. The present invention relates to a method for manufacturing a dome-shaped absorbent article.
A flat circular absorbent body is placed on a long stretch leak-proof sheet made of polyethylene or the like, and an elastic member is attached in an annular shape so as to surround each absorbent body. After the surface sheet is placed and bonded from above, the sheet is punched in an annular shape along each outer periphery of the annular elastic member. As a result, the annular punched sheet is automatically squeezed into a dome shape by restoring the tension of the elastic member.
[0008]
Further, if a dome-shaped absorbent article punched in an annular shape with a topsheet inside is pressed by a hemispherical mold or the like, the dome shape can be easily maintained and can be shaped into a desired dome shape.
By such a production method, the dome-shaped absorbent article of the present invention can be obtained easily and effectively.
Although the dome-shaped absorbent article of the present invention is mainly for incontinence for men, it can also be applied to a breast milk pad for women.
