Abstract

A strong, easy to use high flexibility, low deformation in plane engagement fastening device suitable for use with articles. The fastening device provides a preferred combination of fastenability, flexibility, load bearing, and minimal deformation. The in plane engagement fastening device simplifies and facilitates proper fastener alignment during the fastening process. The fastening device may a projectile and a receptacle. The projectile is passed into or through the receptacle to engage the fastening device.

Claims

1. An in plane engagement fastening device comprising:

a first fastening member, and

a second fastening member, wherein

when the first fastening member and the second fastening member are fastened, the fastening device has a body conformity greater than about 200 percent (%) deflection per kilogram force (kgf).

2. The fastening device of claim 1 wherein the fastening device has a relative deformation of less than about 25% per kgf.

3. The fastening device of claim 1 wherein the fastening device has a body conformity of greater than about 500% per kgf.

4. The fastening device of claim 1 wherein the first fastening member is a tab member, the tab member having a tab load bearing portion with a tab end width and a tab central width, a tab end width to tab central width ratio being greater than about 1.

6. The fastening device of claim 1 wherein the first fastening member is a tab member, the tab member having a laterally overhanging tab member.

7. The fastening device of claim 1 wherein the first fastening member is a tab member, the tab member having a multi-plane hinge.

8. The fastening device of claim 1 wherein the first fastening member is a tab member, the tab member having a single plane hinge.

9. The fastening device of claim 1 wherein the second fastening member is a slot member, the slot member having two longitudinal ends with a slot longitudinal end basis weight, and a slot central region with a slot central region basis weight, the slot longitudinal end basis weight to the slot central region basis weight ratio being greater than about 1.

10. The fastening device of claim 1 wherein the second fastening member is a slot member, the slot member having a slot load bearing portion with a slot load bearing portion longitudinal end width and a slot load bearing portion central region width, and a slot load bearing portion longitudinal end width to slot load bearing portion central width ratio greater than about 1.

11. The fastening device of claim 1 wherein the fastening device has a shear load capability in at least one x-direction and at least one y-direction greater than about 50 grams when the first fastening member is fastened with the second fastening member.

12. The fastening device of claim 1 wherein the fastening device is joined to an article having a first region and a second region, such that the first fastening member is joined to the first region and the second fastening member is joined to the second region.

13. The fastening device of claim 12 wherein the first region is a first waist region, the second region is a second waist region, and the fastening device is configured to connect the first waist region with the second waist region to form a waist hoop having an extensibility of at least about 20% under a load of less than about 2000 grams.

14. The fastening device of claim 12 wherein the article is selected from the group consisting of diaper, sanitary napkin, bib, body wrap and article of clothing.

15. The article of claim 1 wherein the first fastening member is selected from the group consisting of slot members, sockets and receptacles;

and the second fastening member is selected from the group consisting of tab members, rods, and a projectiles.

5. The fastening device of claim I wherein the first fastening device includes a tab member, the tab member includes a tab grip portion with a basis weight, the tab load bearing portion also having a basis weight, a grip portion basis weight to load bearing portion basis weight ratio being less than about 1.

16. An article having a first region, a second region opposed to the first region, the article comprising:

a fastening device for joining at least a portion of the first region with at least a portion of the second region, the fastening device including;

a first fastening member, and

a second fastening member, wherein

when the first and second fastening member are engaged, the fastening device has a body conformity greater than about 200% deflection per kgf load.

17. The article of claim 27 wherein the fastening device has a relative deformation of less than about 25% per kgf of load.

18. The article of claim 28 wherein the article is a diaper, catamenial, bib, body wrap or article of clothing.

19. A fastening device comprising:

a tab member including a single plane hinge, and

a slot member.

20. The fastening device of claim 19, wherein when the tab member and the slot member are fastened, the fastening device has a body conformity greater than about 200% deflection per kgf.

21. The fastening device of claim 20 wherein the fastening device has a relative deformation of less than about 25% per kgf.
