Abstract

An absorbent garment includes a chassis comprised of a moisture impervious outer layer, a moisture pervious inner layer, and an absorbent layer sandwiched between the inner and outer layers. The garment includes one or more elasticized connector tabs attached to the chassis such that part or all of one waist portion of the garment is expandable. The gripping connectors, attached to the distal ends of the connector tabs, interlock with a target connector located near the opposite wait edge of the garment. The waist, made expandable by the integrated elastic connector tabs, conforms to the contours of the user, increasing comfort and improving leak resistance. The connector tabs may be constructed from nonwoven material sandwiching an elastic element or elements.

Claims

1. An absorbent garment comprising:

an outer layer comprised of a liquid impervious material;

a liquid pervious inner layer;

an absorbent layer disposed between the inner and outer layers, the respective layers having opposed first and second laterally extending waist edges with a crotch region therebetween, the first and second waist edges for extending around the waist of a wearer, and two opposed side margins extending generally in a longitudinal direction between the first and second waist edges, and being narrower in at least a portion of the crotch region such that at least one of the outer layer and inner layer forms ears at the second waist edge;

a pair of elastically extensible connector tabs, each having a perimeter defined by a longitudinally extending inboard edge and a longitudinally extending outboard edge with laterally extending side edges therebetween, each inboard edge being located inboard of its respective side margin along the second waist edge by an overlap distance, and each inboard edge being located between the second waist edge and the crotch region, and each outboard edge being located outboard of its respective side margin by a reach distance;

the pair of elastically extensible connector tabs overlapping at least one of the outer layer and inner layer throughout respective overlap areas defined by each respective overlap distance and the longitudinally extending inboard edges of each respective connector tab;

the pair of elastically extensible connector tabs being operably connected to at least one of the outer layer and inner layer in each respective overlap area such that at least one of the outer layer and inner layer to which each connector tab is operably connected is shirred when the connector tab is not extended;

a gripping connector operably connected to each connector tab near the respective longitudinally extending outboard edge of each connector tab, and extending distally therefrom; and

one or more target connectors located along the first waist edge of the outer layer, the target connectors projecting outwardly from the outer layer and adapted each to receive at least one of the gripping connectors.

2. The absorbent garment as recited in claim 1, wherein each connector tab is comprised of a plurality of elastic elements disposed between layers of nonwoven fabric.

3. The absorbent garment as recited in claim 1, wherein each connector tab is comprised of an elastic film element disposed between layers of nonwoven fabric.

4. The absorbent garment as recited in claim 1, wherein each connector tab is comprised of a multidirectional aggregation of elastic elements disposed between layers of nonwoven fabric.

5. The absorbent garment as recited in claim 1, wherein the overlap distance is at least 20 mm when the elastically extensible connector tabs are fully extended.

6. The absorbent garment as recited in claim 1, wherein the reach distance is at least 10 mm when the elastically extensible connector tabs are fully extended.

7. The absorbent garment as recited in claim 1, wherein the longitudinally extending inboard edge has a longitudinal dimension of at least 30 mm.

8. The absorbent garment as recited in claim 1, wherein the longitudinally extending inboard edge has a longitudinal dimension substantially equal to the longitudinal dimension of the ears at the second waist edge.

9. The absorbent garment as recited in claim 1, wherein the connector tabs are approximately 175% longer in their fully extended position than in their relaxed position.

10. The absorbent garment as recited in claim 1, wherein the connector tabs have an elasticity between 5% and 300%.

11. The absorbent garment as recited in claim 1, wherein the connector tabs have a variable spring constant that varies along the lateral dimension of the connector tabs.

12. The absorbent garment as recited in claim 1, wherein the operable connection between the connector tabs and at least one of the outer layer and inner layer is comprised of a plurality of connection points distributed within the overlap area.

13. The absorbent garment as recited in claim 1, wherein the operable connection between the connector tabs and at least one of the outer layer and inner layer is comprised of a substantially continuous connection within the overlap area.

14. The absorbent garment recited in claim 1, wherein the connector tab is operably connected to the exterior surface of the outer layer.

15. The absorbent garment recited in claim 1, wherein the connector tab is operably connected to the exterior surface of the inner layer.

16. The absorbent garment recited in claim 1, wherein the connector tab is operable connected between the outer layer and the inner layer.

17. An absorbent garment comprising:

an outer layer comprised of a liquid impervious material;

a liquid pervious inner layer;

an absorbent layer disposed between the inner and outer layers, the respective layers having opposed first and second laterally extending waist edges with a crotch region therebetween, the first and second waist edges for extending around the waist of a wearer, and two opposed side margins extending generally in a longitudinal direction between the first and second waist edges, and being narrower in at least a portion of the crotch region such that at least one of the outer layer and inner layer forms ears at the second waist edge;

a single elastically extensible connector tab, having a pair of longitudinally extending outboard edges with laterally extending side edges therebetween, each longitudinally extending outboard edge being located outboard of each respective side margin along the second waist edge by a reach distance, [and the laterally extending side edges being located between the second waist edge and the crotch region];

the elastically extensible connector tab overlapping, in a planar sense, at least one of the outer layer and inner layer throughout an overlap area defined by the side margins and the laterally extending side edges;

the elastically extensible connector tab being operably connected to at least one of the outer layer and inner layer in the overlap area such that at least one of the outer layer and inner layer to which the connector tab is operably connected is shirred when the connector tab is not extended;

a gripping connector operably connected to the connector tab near each respective longitudinally extending outboard edge of the connector tab, and extending distally therefrom; and

target connectors located along the first waist edge of the outer layer, the target connectors projecting outwardly from the outer layer and adapted each to receive at least one of the gripping connectors.

18. The absorbent garment as recited in claim 17, wherein the connector tab is comprised of a plurality of elastic elements disposed between layers of nonwoven fabric.

19. The absorbent garment as recited in claim 17, wherein the connector tab is comprised of an elastic film element disposed between layers of nonwoven fabric.

20. The absorbent garment as recited in claim 17, wherein the connector tab is comprised of a multidirectional aggregation of elastic elements disposed between layers of nonwoven fabric.

21. The absorbent garment as recited in claim 17, wherein the reach distance is at least 10 mm when the elastically extensible connector tab is fully extended.
