Abstract

A male incontinence guard has a fluid-impermeable backsheet, a fluid-permeable topsheet facing a user and an absorbent body arranged between the backsheet and the topsheet. The guard has a longitudinal extension along a longitudinal axis and a transverse extension along a transverse axis. The transverse axis divides the guard into an upper and a lower region. The upper region has a greater maximum extension along the transverse axis than the lower region. The absorbent body has primary and secondary cores arranged in a stacked configuration. The primary core has a greater area in an XY plane than the area of the secondary core. The secondary core has side edges that are at least partly generally parallel to the longitudinal axis. Also disclosed is a method for manufacturing the male incontinence guard.

First claim

The invention claimed is:

1. A male incontinence guard comprising a fluid-impermeable backsheet, a fluid-permeable topsheet and an absorbent body arranged between said backsheet and said topsheet, wherein said topsheet faces the user when the incontinence guard is worn by said user, said guard having a longitudinal extension along a longitudinal axis (Y 1 ) and a transverse extension along a transverse axis (X 1 ), said transverse axis (X 1 ) dividing said guard into an upper region and a lower region, said upper region having a greater maximum extension along the transverse axis (X 1 ) than the maximum extension of the lower region along said transverse axis (X 1 ), said absorbent body comprising a primary core and a secondary core arranged in a stacked configuration, wherein said primary core has an area in an XY plane which is greater that the area of said secondary core, and the secondary core is formed with side edges being at least partly generally parallel to said longitudinal axis (Y 1 ), wherein the length of each of said generally parallel side edges is within an interval of 10-70% of a maximum extension of the incontinence guard in a longitudinal direction of the incontinence guard.

2. A male incontinence guard according to claim 1 , wherein said side edges define folding lines for folding said guard in a transverse direction of said guard.

3. A male incontinence guard according to claim 1 , wherein the length of each of said generally parallel side edges is within an interval of 15-60% of the maximum extension of the incontinence guard in the longitudinal direction of the incontinence guard.

4. A male incontinence guard according to claim 1 , wherein a width of said secondary core between said generally parallel side edges is within the interval 25-60% of a maximum width of the guard.

5. A male incontinence guard according to claim 1 , wherein said primary core has an outer edge which generally follows an outer edge of the guard and defines an edge region having a width which is generally equal along the entire outer edge of the guard.

6. A male incontinence guard according to claim 1 , wherein said transverse axis (X 1 ) extends between a first lower corner point and a second lower corner point which define two outermost points of said guard between which said guard has a first width (w 1 ); said upper region comprising an inwardly recessed curvature portion extending between a first upper corner point and a second upper corner point and having an arcuate shape, said first and second upper corner points defining a second width (w 2 ); wherein the first width (w 1 ) is greater than the second width (w 2 ), and wherein said first lower corner point and first upper corner point and said second lower corner point and second upper corner point, respectively, are connected by outer side edges.

7. A male incontinence guard according to claim 6 , said guard being formed with a tapering shape as regarded from the first and second lower corner points and along the lower region.

8. A male incontinence guard according to claim 6 , wherein the second width (w 2 ) is in the range of 30-80% of the first width (w 1 ).

9. A male incontinence guard according to claim 6 , wherein the first width (w 1 ) is in the range of 110-280 mm.

10. A male incontinence guard according to claim 6 , wherein the second width (w 2 ) is in the range of 50-151 mm.

11. A male incontinence guard according to claim 6 , wherein a ratio between a distance (d 1 ) defined by an imaginary longitudinal line (Y 2 ), being parallel to said longitudinal axis (Y 1 ) and extending from any one of said first or second upper corner points to said transversal axis (X 1 ), and a distance (d 2 ) extending from any one of said first or second lower corner points to said longitudinal line (Y 2 ), is in the range of 0.25-4.0.

12. A male incontinence guard according to claim 11 , wherein a straight line is defined as extending through a lower corner point and an upper corner point, and wherein an angle (α) is defined between said straight line and said imaginary longitudinal line (Y 2 ), said angle (α) being in the range of 12-78 degrees.

13. A male incontinence guard according to claim 12 , wherein a measurement (d 4 ) is defined as the distance between said straight line and the maximum outer extension of said incontinence guard, said measurement (d 4 ) being in the range of 2-10 mm, or wherein said measurement (d 4 ) is less than 25% of the distance between first lower corner point and the first upper corner point.

14. A male incontinence guard according to claim 6 , wherein a maximum recess depth (d 3 ) of said inwardly recessed curvature portion does not extend below said transversal axis (X 1 ).

15. A male incontinence guard according to claim 14 , wherein said maximum recess depth (d 3 ) is the range of 2-30 mm.

16. A male incontinence guard according to claim 6 , wherein said lower region of said guard comprises a lower edge having a convex arcuate shape with a radius (r 2 ) defining a ratio of 0.9-1.1 to said radius (r 1 ) of said inwardly recessed curvature portion.

17. A male incontinence guard according to claim 6 , wherein said outer side edges are generally straight.

18. A male incontinence guard according to claim 1 , wherein at least one of said primary core and said secondary core comprises superabsorbent material.

19. A male incontinence guard according to claim 18 , wherein said superabsorbent material is a superabsorbent polymer.

20. A male incontinence guard according to claim 18 , wherein said superabsorbent material is in the form of a foam.

21. A male incontinence guard according to claim 1 , wherein said guard is arranged having elasticized elements arranged along an outer edge of the lower region, along the outer edges of said lower region.

22. A male incontinence guard according to claim 21 , wherein said elasticized elements are in the form of an elasticized film attached to said guard.

23. A male incontinence guard according to claim 21 , wherein said elasticized elements are in the form of elastic threads attached to said guard.

24. A male incontinence guard according to claim 21 , wherein said elasticized elements are in the form of an elastic foam attached to said guard.

25. A male incontinence guard according to claim 21 , wherein said elasticized elements are in the form of an elastic laminate attached to said guard.

26. The male incontinence guard according to claim 1 , wherein the length of each of said generally parallel side edges is within an interval of 20-50% of the maximum extension of the incontinence guard in the longitudinal direction of the incontinence guard.

27. A male incontinence guard comprising a fluid-impermeable backsheet, a fluid-permeable topsheet and an absorbent body arranged between said backsheet and said topsheet, wherein said topsheet faces the user when the incontinence guard is worn by said user, said guard having a longitudinal extension along a longitudinal axis (Y 1 ) and a transverse extension along a transverse axis (X 1 ), said transverse axis (X 1 ) dividing said guard into an upper region and a lower region, said upper region having a greater maximum extension along the transverse axis (X 1 ) than the maximum extension of the lower region along said transverse axis (X 1 ), said absorbent body comprising a primary core and a secondary core arranged in a stacked configuration, w
