DESCRIPTION:
BRIEF SUMMARY
The present application claims the benefit of International Application No. PCT/SE95/00538, which was filed on May 15, 1995, and which claims the priority of Swedish Patent Application No. 9401680-5, which was filed on May 16, 1994.
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a disposable liquid-absorbent article according to the preamble of the appended claim 1.
DESCRIPTION OF RELATED ART
Liquid-absorbent articles, for example diapers, provided with elastics in order to give the article its shape in an in-use position, are known in the prior art. In most articles of this kind the main purpose of the elastics is to provide, at the wearer's crotch, a raised edge, sealing against the wearer's legs. Hitherto known solutions, however, offer a limited capacity concerning the ability to locally collect and contain larger volumes of for instance faeces and urine.
From for example U.S. Pat. No. 3,860,003, a diaper is known, where leg elastics provide a circumferential cuff around the legs. In the spread-out position of the article, the elastics are fully rectilinear and substantially extending along the side of the absorption body in order to make the edge of the diaper seal against the legs in an in-use position.
U.S. Pat. No. 4,050,462 refers to a diaper with elastics extending rectilinearly in the flat condition of the diaper and serves to contract the crotch section of the diaper and, by folding, increase the surface and the volume per length unit for the absorption body in order to achieve an enhanced absorption effect.
WO 88/00010 shows a diaper having substantially rectilinear elastics, forming a V-shaped configuration. The elastics extend over the absorption body of the diaper and delimit an area that is altered in shape by the contracting effect of the elastics. By the extension of the elastics with rectilinear sections, a folding of the article as a whole is substantially achieved as a result of the tendency of the elastics to reduce the entire length of the article.
U.S. Pat. No. 4,801,345 shows a method for the manufacture of diapers. The method includes the application of elastics along the crotch section of the diapers. The elastics hereby extend concavely outwards along the longitudinal edges of the diaper and completely to the side of the absorption body. The purpose of the elastics is mainly to achieve a sealing contact between the edge of the diaper and the wearer's legs. A further effect will be a certain contraction and folding of the absorption body over the crotch section.
EP 0 219 326 shows a diaper with elastics, extending completely rectilinearly in the diaper's flat state and completely to the side of the absorption body. Elastics are arranged partly at the outer edge of the diaper on each side of the crotch section and partly in an edge-band on each side of the absorption body. In addition to maintaining an upstanding, sealing edge by way of the edge-band, the elastics ensure a certain folding and contraction of the absorption body.
GB 2 234 157 relates to a diaper with elastics extending around the waistline of the trousers, and along the edge of the crotch section against the wearer's legs and also across the crotch section. The elastics for sealing around the legs reduce the risk of leakage, while the elastics across the crotch section are merely arranged to enable a rational application of continuous elastic cord. The composition and method is specially adapted to trouser-shaped diapers.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a liquid-absorbent article for disposable use, which in a user position is given a highly efficient collecting shape.
Ever since diapers with leg elastics according to U.S. Pat. No. 3,860,003 became common during the seventies a great number of patent applications referring to diaper elastics have been filed worldwide.
Elastics have been applied along and/or across the diaper in order to create a 3-dimensional shape or leakage barriers.
Elastics have further been applied in a curved shaped along
