Abstract

Feminine hygiene articles are disclosed herein. The feminine hygiene articles described herein can provide easily discernable placement and orientation guides which reduce the likelihood of misapplication by the user, facilitated attachment guides which can reduce the likelihood of misapplication of the feminine pad and can also reduce the likelihood of improper attachment of the feminine pad to a panty. The feminine hygiene articles disclosed include wings which can provide cues on proper attachment of the article to the panty, and wing adhesive distributed in a way which can provide sustained coverage of the feminine hygiene article to the panty which reduces the likelihood that the pad will become detached during use.

Claims (25)

1. A feminine hygiene article having a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, a longitudinal centerline and a lateral centerline perpendicular to the longitudinal centerline, the feminine hygiene article further comprising:

a first wing extending laterally outboard of the chassis having a first leading edge extending outboard of the chassis, a first trailing edge extending outboard of the chassis and a first curvilinear edge connecting the first leading edge and the first trailing edge, wherein a first fold line is positioned intermediate the chassis and the first wing, wherein the first curvilinear edge forms an outermost portion of the first wing, the first wing further comprising a first zone and a second zone and a first bisecting line forming at least a portion of a boundary between the first zone and the second zone, wherein the first wing is asymmetric about the first bisecting line, wherein at least a portion of the second zone is disposed more outboard of the chassis than the first zone, wherein the first leading edge forms a first angle with respect to the first fold line;

a second wing extending laterally outboard of the chassis having a second leading edge extending outboard of the chassis, a second trailing edge extending outboard of the chassis and a second curvilinear edge connecting the second leading edge and the second trailing edge, wherein a second fold line is positioned intermediate the chassis and the second wing, wherein the second curvilinear edge forms an outermost portion of the second wing, the second wing further comprising a third zone and a fourth zone and a second bisecting line forming at least a portion of a boundary between the third zone and the fourth zone, wherein the second wing is asymmetric about the second bisecting line, wherein at least a portion of the fourth zone is disposed more outboard of the chassis than the third zone, wherein the second trailing edge forms a second angle with respect to the second fold line;

wherein the first angle and the second angle are positioned on opposite sides of the lateral centerline of the feminine hygiene article.

2. The feminine hygiene article of claim 1 , wherein the first angle and the second angle are the same.

3. The feminine hygiene article of claim 1 , wherein the first angle is disposed in the first zone and the second angle is disposed in the third zone.

4. The feminine hygiene article of claim 1 , wherein the first wing further comprises a first visual signal and the second wing comprises a second visual signal.

5. The feminine hygiene article of claim 1 , wherein the first wing further comprises a first surface and an opposing second surface, and a first adhesive area disposed on the second surface, wherein the first adhesive area is disposed in the second zone.

6. The feminine hygiene article of claim 5 , wherein the second wing further comprises a first surface and an opposing second surface, and a second adhesive area disposed on the second surface, wherein the second adhesive area is disposed in the fourth zone.

7. The feminine hygiene article of claim 6 , wherein the first wing and the second wing each comprise a grasping area.

8. The feminine hygiene article of claim 1 , wherein the first angle is positioned proximal to a front end of the feminine hygiene article.

9. The feminine hygiene article of claim 1 , further comprising a secondary topsheet, where the secondary topsheet is asymmetrical about the lateral centerline of the feminine hygiene article.

10. The feminine hygiene article of claim 9 , wherein the secondary topsheet has a variable width.

11. A feminine hygiene article having a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, a longitudinal centerline and a lateral centerline perpendicular to the longitudinal centerline, the feminine hygiene article further comprising:

a first wing extending laterally outboard of the chassis having a first leading edge extending outboard of the chassis, a first trailing edge extending outboard of the chassis and a first curvilinear edge connecting the first leading edge and the first trailing edge, wherein a first fold line is positioned intermediate the chassis and the first wing, wherein the first curvilinear edge forms an outermost portion of the first wing, the first wing further comprising a first zone and a second zone and a first bisecting line forming at least a portion of a boundary between the first zone and the second zone, wherein the first wing is asymmetric about the first bisecting line, wherein the first leading edge forms a first angle with respect to the first fold line, wherein the trailing edge forms a second angle with respect to the first fold line, wherein the first angle and the second angle are different;

a second wing extending laterally outboard of the chassis having a second leading edge extending outboard of the chassis, a second trailing edge extending outboard of the chassis and a second curvilinear edge connecting the second leading edge and the second trailing edge, wherein a second fold line is positioned intermediate the chassis and the second wing, wherein the second curvilinear edge forms an outermost portion of the second wing, the second wing further comprising a third zone and a fourth zone and a second bisecting line forming at least a portion of a boundary between the third zone and the fourth zone, wherein the second wing is asymmetric about the second bisecting line, wherein the second trailing edge forms a third angle with respect to the second fold line, wherein the second leading edge forms a fourth angle with respect to the second fold line, wherein the third and fourth angle are different.

12. The feminine hygiene article of claim 11 , wherein the first angle and the second angle are positioned on opposite sides of the lateral centerline of the feminine hygiene article.

13. The feminine hygiene article of claim 11 , wherein the first angle and the third angle are positioned on opposite sides of the lateral centerline of the feminine hygiene article.

14. The feminine hygiene article of claim 11 , wherein the first angle is more proximal to the front end of the feminine hygiene article than the second angle.

15. The feminine hygiene article of claim 11 , wherein the first angle is disposed in the first zone and the second angle is disposed in the second zone.

16. The feminine hygiene article of claim 15 , wherein the first wing further comprises a first surface and an opposing second surface, and a first adhesive area disposed on the second surface, wherein the first adhesive area is disposed in the second zone.

17. The feminine hygiene article of claim 11 , wherein the third angle is disposed in the third zone and the fourth angle is disposed in the fourth zone.

18. The feminine hygiene article of claim 17 , wherein the second wing further comprises a first surface and an opposing second surface, and a second adhesive area disposed on the second surface, wherein the second adhesive area is disposed in the fourth zone.

19. The feminine hygiene article of claim 18 , wherein the first wing and the second wing each comprise a grasping area.

20. The feminine hygiene article of claim 11 , wherein the first wing further comprises a first visual signal and the second wing comprises a second visual signal.
