Abstract
Abstract An elongated absorbent article, such as a diaper or an incontinence protector, comprises an absorption body disposed in a casing and having between its two ends a crotch portion. The absorption body comprises a bottom sheet (1) and a top sheet (2), the top sheet being adapted to lie in contact with the wearer and to serve as a spacer means between the skin of the wearer and the bottom sheet. The top sheet (2) has parts (9, 10) which are located along two side-edge portions of the bottom sheet and which define laterally between them at least one space (7) around a wetting point of the article. These parts (9, 10) located along the side-edge portions of the bottom sheet have an extent such that the article has within the regions of the parts (9, 10) a much higher flexural resistance than the remainder of the article, such that when the article is positioned on the wearer, the portion of the article located between those parts (9, 10) is curved both laterally and transversely such as to impart a basin-like configuration to the space around the wetting point (7).

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
171 words
An elongated absorbent article, such as a diaper or an incontinence protector, comprising an absorption body disposed in a casing and having between its two ends a crotch portion, the absorption body comprising a bottom layer (1) and a top layer (2), said top layer having a thickness such that said top layer is adapted to serve as a spacer means between the wearer and the bottom layer; said top layer (2) having parts (9, 10) which are located along two sideedge portions of the bottom layer and which define laterally between them at least one space (7) around a wetting point of the article; the thickness of said parts being such that the article has within the regions of said parts (9, 10) a much higher flexural resistance than the remainder of said article, such that when the article is positioned on the wearer the portion of the article located between said parts (9, 10) is curved both laterally and transversely in a basin-like configuration around said wetting point (7).
Claim 2
Dependent Claim
171 words
An elongated absorbent article, such as a diaper or an incontinence protector, comprising an absorption body disposed in a casing and having between its two ends a crotch portion, the absorption body comprising a bottom layer (1) and a top layer (2), said top layer having a thickness such that said top layer is adapted to serve as a spacer means between the wearer and the bottom layer; said top layer (2) having parts (9, 10) which are located along two sideedge portions of the bottom layer and which define laterally between them at least one space (7) around a wetting point of the article; the thickness of said parts being such that the article has within the regions of said parts (9, 10) a much higher flexural resistance than the remainder of said article, such that when the article is positioned on the wearer the portion of the article located between said parts (9, 10) is curved both laterally and transversely in a basin-like configuration around said wetting point (7).
Claim 3
Dependent Claim
75 words
An absorbent article according to claim 1, in which the top layer (2) extends across the whole width of the crotch part of the diaper, such that the crotch part is highly resistance to flexural forces and resistant to deformation forces; said parts (9, 10) comprising branches which diverge outwardly from the crotch part at least in a direction toward an end of the article and which serve as borders defining the basin-like space (7).
Claim 4
Dependent Claim
23 words
An article according to claim 1, in which the article is symmetrical about a transverse centerline of the crotch part of said article.
Claim 5
Dependent Claim
43 words
An article according to claim 1, in which both the top layer (2) and the bottom layer (1) of the article are connected with the casing (3, 4) embracing the absorbent body on the sides thereof which face the wearer's body in use.
Claim 6
Dependent Claim
21 words
An article according to claim 1, in which the bottom layer (1) is compressed more compactly than the top layer (2).
Claim 7
Dependent Claim
27 words
An article according to claim 5, in which the top and bottom layers (2, 1) consist of two mutually separate pieces which have been subsequently joined together.
Claim 8
Dependent Claim
24 words
An article according to claim 1, in which the two layers (1, 2) included in the absorbent body are made from mutually different materials.
Claim 9
Dependent Claim
26 words
An article according to claim 7, in which the top layer (2) is made of synthetic fiber wadding and the bottom layer (1) of cellulose fluff.
Claim 10
Dependent Claim
19 words
An article according to claim 1, in which the absorbent body is formed of airlaid and compressed cellulose fluff.
Claim 11
Dependent Claim
87 words
An elongated absorbent article, such as a diaper or an incontinence protector, comprising an absorption body disposed in a casing and having between its two ends a crotch portion, the absorption body comprising a bottom layer (1) and a top layer (2), said top layer having a thickness such that said top layer is adapted to serve as a spacer between the wearer and the bottom layer; said top layer (2) being X-shaped and having a longitudinal midportion coinciding with said crotch portion of said absorbent article.
Claim 12
Dependent Claim
87 words
An elongated absorbent article, such as a diaper or an incontinence protector, comprising an absorption body disposed in a casing and having between its two ends a crotch portion, the absorption body comprising a bottom layer (1) and a top layer (2), said top layer having a thickness such that said top layer is adapted to serve as a spacer between the wearer and the bottom layer; said top layer (2) being X-shaped and having a longitudinal midportion coinciding with said crotch portion of said absorbent article.
Claim 13
Dependent Claim
