Elastic laminates and methods for assembling elastic laminates for absorbent articles
The present disclosure relates to elastic laminates and methods for assembling elastic laminates that may be used to make absorbent article components. Elastic laminates may include one or more reinforcement layers positioned between unstretched portions of elastic materials and substrates to which the elastic materials are bonded.
1. A taped absorbent article comprising:
a topsheet;
a backsheet;
an absorbent core positioned at least partially intermediate the topsheet and the backsheet;
a front waist region;
a back waist region; and
an elastic waist band joined to the front waist region or the back waist region;
wherein the elastic waist band comprises:
a first nonwoven substrate;
a second nonwoven substrate; and
an elastic material positioned at least partially intermediate the first nonwoven substrate and the second nonwoven substrate;
wherein the first nonwoven substrate partially overlaps itself to create a folded over portion of the first nonwoven substrate, wherein the folded over portion is in direct facing contact with a non-folded over portion of the first nonwoven substrate;
wherein the folded over portion overlaps a first portion of the elastic material; and
wherein the elastic material is free of overlap from itself.
2. The taped absorbent article of claim 1 , wherein the elastic material is generally planar and free of folds.
3. The taped absorbent article of claim 1 , comprising a fastener comprising a fastener element joined to the front waist region or the back waist region.
4. The taped absorbent article of claim 1 , comprising a reinforcement layer intermediate the first nonwoven substrate and the second nonwoven substrate.
5. The taped absorbent article of claim 4 , wherein the reinforcement layer overlaps a second portion of the elastic material.
6. The taped absorbent article of claim 4 , wherein the reinforcement layer is positioned proximate to a first end of the elastic waist band, and wherein the folded over portion is positioned proximate to a second end of the elastic waist band.
7. The taped absorbent article of claim 1 , wherein the elastic waist band comprises a plurality of ultrasonic bonds.
8. The taped absorbent article of claim 1 , wherein the elastic waist band is joined to the back waist region, and wherein the first nonwoven substrate is the same material as the second nonwoven substrate.
9. A taped absorbent article comprising:
a topsheet;
a backsheet;
an absorbent core positioned at least partially intermediate the topsheet and the backsheet;
a front waist region;
a back waist region; and
an elastic waist band joined to the front waist region or the back waist region;
wherein the elastic waist band comprises:
a first nonwoven substrate;
a second nonwoven substrate; and
an elastic material positioned at least partially intermediate the first nonwoven substrate and the second nonwoven substrate;
wherein the first nonwoven substrate comprises one layer in a first portion and two layers in a second portion, wherein the two layers comprise material of the first nonwoven substrate folded over and in direct facing contact with itself; and
wherein the elastic material is free of overlap from itself.
10. The taped absorbent article of claim 9 , wherein the elastic material is generally planar and free of folds.
11. The taped absorbent article of claim 9 , wherein the second portion of the first nonwoven substrate overlaps a portion of the elastic material.
12. The taped absorbent article of claim 9 , comprising a fastener comprising a fastener element joined to the front waist region or the back waist region.
13. The taped absorbent article of claim 9 , comprising a reinforcement layer intermediate the first nonwoven substrate and the second nonwoven substrate.
14. The taped absorbent article of claim 13 , wherein the reinforcement layer overlaps a portion of the elastic material.
15. The taped absorbent article of claim 13 , wherein the reinforcement layer is positioned proximate to a first end of the elastic waist band, and wherein the folded over portion is positioned proximate to a second end of the elastic waist band.
16. The taped absorbent article of claim 9 , wherein the elastic waist band comprises a plurality of ultrasonic bonds formed through the first nonwoven substrate, the second nonwoven substrate, and the elastic material.
17. A taped absorbent article comprising:
a topsheet;
a backsheet;
an absorbent core positioned at least partially intermediate the topsheet and the backsheet;
a front waist region;
a back waist region;
an elastic waist band joined to the front waist region or the back waist region;
wherein the elastic waist band comprises:
a first nonwoven substrate;
a second nonwoven substrate;
an elastic material positioned at least partially intermediate the first nonwoven substrate and the second nonwoven substrate;
wherein a first portion of a surface of the first nonwoven substrate directly faces and contacts a second portion of the surface of the first nonwoven substrate; and
a plurality of ultrasonic bonds formed through the first nonwoven substrate, the second nonwoven substrate, and the elastic material;
wherein the elastic material is free of overlap from itself.
18. The taped absorbent article of claim 17 , comprising a fastener joined to the front waist region or the back waist region.
19. The taped absorbent article of claim 17 , further comprising a reinforcement layer positioned at least partially intermediate the first nonwoven substrate and the second nonwoven substrate, wherein the reinforcement layer comprises a section of material that is distinct from the first nonwoven substrate and the second nonwoven substrate.
20. The taped absorbent article of claim 19 , wherein the reinforcement layer overlaps a portion of the elastic material.
