Abstract
An absorbent article has an elastic waist portion, an absorbent element (5), and a liquid-impermeable outer layer (3) which is intended to enclose the absorbent element on at least that side thereof which faces away from the wearer during use of the article. The absorbent element (5) is in its entirety arranged on the second piece (2). The liquid-impermeable outer layer (3) is breathable, at least over a portion of this which covers the absorbent element (5).
Claims49
An absorbent article of pants shape, comprising an elastic waist portion, an absorbent element which has a length and a width and is adapted to at least cover the genitals of a wearer when the article is worn, and a liquid-impermeable outer layer which is adapted to enclose the absorbent element on at least a side thereof which faces away from the wearer when the article is worn, the elastic waist portion is made from an elastic first piece which is elongate in an extended state and is adapted to partly surround a trunk of the wearer and to form a rear portion and side portions of the article, a second piece forms part of the article and is adapted to form a front portion and a crotch portion of the article, said second piece is elongate with two opposite end edges and two opposite longitudinal edges, the width of the second piece is, at least in the crotch portion, smaller than a length of the first piece, the second piece is arranged with a longitudinal direction at right angles in relation to a longitudinal direction of the first piece and is connected by a first of the end edges of the second piece to one longitudinal edge of the first piece, centrally thereon, one end portion of the first piece is connected to a first longitudinal edge of the second piece, and an other end portion of the first piece is connected in a corresponding manner to a second longitudinal edge of the second piece, and the absorbent element is in its entirety arranged on the second piece, and at least a portion of the liquid-impermeable outer layer which covers the absorbent element is breathable.
An absorbent article, comprising:
- an elastically stretchable first piece having first and second longitudinal edges and first and second end portions, wherein the first and second end portions are shorter than the first and second longitudinal edges;
- a second piece having first and second longitudinal edges and first and second end portions, wherein the first and second end portions are shorter than the first and second longitudinal edges;
- the first end portion of the second piece is secured to a middle portion of the second longitudinal edge of the first piece so that the first piece extends substantially perpendicular to the second piece;
- the first end portion of the first piece is secured to the first longitudinal edge of the second piece and the second end portion of the first piece is secured to the second longitudinal edge of the second piece;
- an absorbent element secured to the second piece;
- and
- a liquid-impermeable sheet covering the absorbent element, the absorbent element arranged between the second piece and the liquid impermeable sheet, and at least a portion of the liquid-impermeable sheet covering the absorbent element is vapor-permeable.
A method of manufacturing an absorbent article of pants shape, the article comprising an elastic waist portion, an absorbent element, which has a length and a width and is adapted to at least cover genitals of a wearer when the article is worn, and a liquid-impermeable outer layer which is adapted to enclose the absorbent element on at least a side thereof which faces away from the wearer, the method comprising:
- making said elastic waist portion from an elastic first piece which is essentially rectangular in an extended state and is adapted to partly surround a trunk of the wearer so as to form from the first piece;
- a rear portion and side portions of the article from the first piece;
- forming a front portion and a crotch portion of the article from a second piece, said second piece is elongate with two opposite end portions and two opposite longitudinal edges, a width of the second piece is, at least in the crotch portion, smaller than a length of the first piece;
- arranging the second piece with a longitudinal direction at right angles in relation to a longitudinal direction of the first piece and connecting a first end portion of the second piece to one longitudinal edge of the first piece, centrally thereon, connecting one end portion of the first piece to a first longitudinal edge of the second piece, and another end portion of the first piece in a corresponding manner to a second longitudinal edge of the second piece, and wherein at least a portion of the liquid-impermeable outer layer, which portion is intended to cover the absorbent element, is formed from a breathable material.
39 Method according to claim 38, further comprising arranging the absorbent element in its entirety on the second piece forming part of the article before said second piece is connected to said first piece.
Method according to claim 39, wherein the absorbent element, before being arranged on the second piece, is provided with a liquid-impermeable and breathable layer.
A method of manufacturing an absorbent article, comprising:
- providing an elastically stretchable first piece having first and second longitudinal edges and first and second end portions, wherein the first and second end portions are shorter than the first and second longitudinal edges;
- securing an absorbent element to a second piece of material so that the absorbent element is arranged between the second piece of material and a liquid-impermeable sheet, wherein at least a portion of the liquid-impermeable sheet covering the absorbent element is vapor-permeable;
- securing a first end portion of a second piece of material to a middle portion of the second longitudinal edge of the first piece so that the first piece extends substantially perpendicular to the second piece, wherein the second piece has first and second longitudinal edges that are substantially perpendicular to the first end portion and the first end portion is shorter than the first and second longitudinal edges, and wherein the second piece includes an absorbent element;
- and
- securing the first end portion of the first piece to the first longitudinal edge of the second piece and securing the second end portion of the first piece to the second longitudinal edge of the second piece.
The method of claim 48, wherein the absorbent element is hourglass shaped.
