Abstract

A pant diaper or diaper whose side edges are joined to form a pants-like shape with the help of strips provided with interacting hook and loop devices respectively that extend along the long edges of the front and rear sections. The edges of the strips that face the legs are covered by a band of soft and flexible material.

Claims

1. Diaper or pant diaper comprising:

a front section, a rear section, and an intermediate crotch section having a narrower width than the front and rear sections, and a longitudinal line of symmetry extending from a middle of a rear edge of the rear section to a middle of a front edge of the front section,

an absorption body enclosed between a inner surface layer of liquid-permeable material and an outer surface layer of liquid-impermeable material whereby side parts of the front and rear sections can be joined to one another by a refastenable closure by means of a first mechanical join so that the diaper or pant diaper, in a position of use where the side parts are joined to one another in an over-lapping manner, acquires a pants-like configuration with one waist opening and two leg openings, and

a band of soft and flexible material, whose one end is permanently attached to the side part of one of the front or rear section that, when in the position of use, is overlapped by the side part of the other of the front or rear section,

wherein, in the position of use, the band is folded over each edge of one of the leg openings and refastenable to the outside of the overlapping side part of the mutually joined side parts by means of a second join.

2. The diaper or pant diaper according to claim 1, wherein each band has a width and placement such that in a cross-sectional direction each band extends over a whole width of the first mechanical join.

3. The diaper or pant diaper according to claim 1, wherein one end of the band is attached to the inner surface layer of the side part of the section of the front or rear section that, in the position of use, is overlapped by the side part of the other section.

4. The diaper or pant diaper according to claim 1, wherein one end of the band is attached to the outer surface layer of the side part of the section of the front or rear section that, in the position of use, is overlapped by the side part of the other section.

5. The diaper or pant diaper according to claim 1, wherein a band of soft and flexible material, having one end permanently attached to the side part of the section of the front or rear section that, in the position of use, is overlapped by the side part of the other section, is, in the position of use, folded over each edge of the waist opening and refastenable to the outside of the overlapping side part of the mutually joined side parts.

6. The diaper or pant diaper according to claim 5, wherein each band extends from the leg opening to the waist opening of the side part to which the band is permanently attached.

7. The diaper or pant diaper according to claim 1, wherein the first mechanical join comprises interacting hook and loop devices.

8. The diaper or pant diaper according to claim 1, wherein the second mechanical join comprises interacting hook and loop devices.

9. The diaper or pant diaper according to claim 1, wherein the liquid-impermeable surface layer includes an outwards facing non-woven layer and that the band includes hook devices than can be attached to the liquid-impermeable surface layer.

10. The diaper or pant diaper according to claim 1, wherein the band is made of nonwoven material with a surface weight greater than 30 g/m².

11. The diaper or pant diaper according to claim 1, wherein the band is made of nonwoven material, one side of which is at least partly covered with a layer of foam plastic.

12. The diaper or pant diaper according to claim 1, wherein the band is thicker in a part of the band which, in the position of use, extends over the edge of the leg opening.

13. Diaper or pant diaper according to claim 1, wherein each band, in the position of use, extends over the whole length of the associated first mechanical join on the inside and/or outside of this join.
