Abstract

An absorbent article in the form of pants includes: an absorbent core having two longitudinal edges and two transverse edges, and a pant part. The pant part includes a covering layer, a front section, a back section and an intermediate crotch section, wherein the front and back sections are connected to one another along two opposing longitudinal lateral edges to form a waist opening and a pair of leg openings. The absorbent core is arranged at least in the crotch section and connected to the covering layer on the side of the covering layer that is intended to face the wearer. The pant part includes at least one low-opacity area, which has an opacity that is lower than 50%. The article also includes a liquid-tight coloured barrier layer placed between said absorbent core and covering layer.

Claims (22)

1. An absorbent article in the form of pants comprising:

a pant part, wherein said pant part comprises a covering layer, a front section, a back section and an intermediate crotch section, wherein the front and back sections are connected to one another along two opposing longitudinal lateral edges to form a waist opening and a pair of leg openings, wherein said pant part comprises at least one low-opacity area, which has an opacity that is lower than or equal to 30%;

an absorbent core having two longitudinal edges and two transverse edges, said absorbent core being arranged in at least the crotch section and connected to the covering layer on the side of the covering layer that is intended to face the wearer such that the low-opacity area of said pant part covers at least a portion of the absorbent core; and

a liquid-tight coloured barrier layer placed between said absorbent core and covering layer, extension of the barrier layer coinciding on the whole with extension of the absorbent core and at least a portion of the barrier layer is covered by the low-opacity area of said pant part,

wherein said barrier layer has a skin-like colour with an L* value of 30.1-67.9, a* value of 5.5-7.0 and b* value of 7.5-20.3 in accordance with the CIE L*a*b* standard method, and

wherein the difference between two colours in the colour space CIE L*a*b*, which is characterised by a Delta E-value (ΔE*ab) in a comparison between the low-opacity area/areas of the pant part covering the barrier layer and the low-opacity area/areas of the pant part outside the area of the barrier layer's extension is less than:

4 when said low-opacity area for the pant part has an opacity of 30%

3 when said low-opacity area for the pant part has an opacity of 20-30%

2 when said low-opacity area for the pant part has an opacity of 0-20%,

when the absorbent article is placed with the side that is intended to face the wearer against a reference surface having a predetermined colour, in accordance with the CIEL*a*b* standard method, wherein the reference surface is formed of a surface that has the following L*, a*, b* value: L*=67.9 a*=5.5 and b*=16.4 or L*=52.6 a*=7.0 and b*=20.3 or L*=30.1 a*=5.8 and b*=4.5*, and

wherein said pant part has a base colour that is different from the skin-like colour of said barrier layer.

2. The absorbent article according to claim 1 , wherein the low-opacity area partly constitutes the area of the extension of the barrier layer and the area outside the core's edges, which adjoin around the extension of the core.

3. The absorbent article according to claim 1 , wherein the covering layer is formed of an elastic nonwoven.

4. The absorbent article according to claim 1 , wherein the covering layer is formed of an elastic laminate consisting of at least one layer and a textile-like layer.

5. The absorbent article according to claim 1 , wherein the covering layer is formed of two layers with a plurality of intermediate elastic elements.

6. The absorbent article according to claim 1 , the core comprises a surface layer facing towards the wearer.

7. The absorbent article according to claim 6 , wherein the surface layer corresponds to the extension of the barrier layer.

8. The absorbent article according to claim 7 , wherein the surface layer and the barrier layer are connected to one another, for example, by gluing, sewing, or welding using heat or ultrasound.

9. The absorbent article according to claim 1 , wherein the pant part has a base colour that is selected from white, black, red, blue, violet, orange, yellow, green or indigo, as well as any other hue or mix thereof.

10. The absorbent article according to claim 1 , wherein the pant part has a graphic pattern.

11. A packaging containing a plurality of absorbent articles, wherein at least one of the plurality of absorbent articles is the absorbent article according to claim 1 , wherein the packaging has a code for skin tone.

12. The packaging according to claim 11 , wherein the code is formed of a colour shade, which corresponds to the colour of the reference skin tone, a colour scale in colour in which the reference skin tone is depicted together with the surrounding skin tones, or it is stated in words which skin tone the article is designed for: for example, a Light skin tone, Yellow/Red skin tone or Dark skin tone, or a drawn figure in the shape of a person having the intended skin tone that the article is intended to match.
