Absorbent articles with external access to internal conductors
View Patent ↗An absorbent article includes a liner and an outercover in facing relation and at least one conductive element located between the liner and the outercover. At least a portion of the conductive element is exposed through the liner and/or the outercover to define at least one external contact point. The external contact point defines a perimeter and the liner and/or the outercover is sealed about the perimeter. The contact points provide external access to the internal conductive elements.
1. An absorbent article comprising,
a liner and a outercover in facing relation; and
at least one conductive element located between the liner and the outercover, wherein at least a portion of the conductive element is exposed through at least one of the liner and the outercover to define at least one external contact point and wherein the at least one external contact point defines a perimeter and wherein at least one of the liner and the outercover is sealed about the perimeter.
2. The absorbent article of claim 1 wherein at least one external contact point extends at least partially through the outercover.
3. The absorbent article of claim 1 wherein the conductive elements are intact proximate the external contact point.
4. The absorbent article of claim 1 wherein the conductive element is a laminate comprising a conductive layer and a masking layer.
5. The absorbent article of claim 4 wherein the conductive element is oriented towards the outercover and the masking layer is oriented towards the liner.
6. The absorbent article of claim 1 having a length and further comprising a first conductive element and a second conductive element, wherein both the first conductive element and the second conductive element extend the length of the absorbent article.
7. The absorbent article of claim 6 wherein the first conductive element and the second conductive element have a plurality of portions extending at least partially through the outercover to define a plurality of external contact points.
8. The absorbent article of claim 1 wherein the outercover and the liner are joined together at bond points that do not include the conductive element.
9. A kit comprising the absorbent article of claim 1 and a signaling device wherein the absorbent article includes a plurality of external contact points formed in the shape of a first indicia and the signaling device includes a second indicia wherein the first and second indicia aid alignment of the signaling device relative to the absorbent article.
10. An absorbent article having a length and comprising,
a liner and an outercover in facing relation; and
a first conductive element and a second conductive element located between the liner and the outercover and extending the length of the absorbent article,
wherein a plurality of portions of the first conductive element and the second conductive element are at least partially exposed through the outercover to define a plurality of external contact points and
wherein each external contact point defines a perimeter and the outercover is sealed about each perimeter.
11. The absorbent article of claim 10 wherein the liner and the outercover are joined together at bond points in areas not including the first or the second conductive elements.
12. The absorbent article of claim 10 wherein the plurality of external contact points are adapted to provide a first indicia for aligning a signaling device with the absorbent article to ensure electrical connectivity.
13. A kit comprising the absorbent article of claim 12 and a signaling device wherein the signaling device includes a second indicia adapted to align with the first indicia to ensure proper electrical connectivity.
14. A method of exposing portions of internally positioned conductive elements to an external surface of an absorbent article, comprising,
providing an outercover and liner in facing relation with a conductive element located therebetween;
at least partially exposing a portion of the conductive element through the outercover to define at least one external contact point on an outer article surface; and
sealing the outercover about a perimeter of the at least one external contact point by at least partially melting portions of the outercover.
15. The method of claim 14 wherein the outercover, the liner, and the conductive element are provided as a part of an interconnected web of absorbent articles.
16. The method of claim 14 wherein the exposing step utilizes pressure bonding, ultrasonic bonding, or thermal bonding.
17. The method of claim 16 wherein the exposing step also extends the portion of the conductive element at least partially through the outercover.
18. The method of claim 14 wherein the steps of exposing a portion of the conductive element and sealing the outercover occur in the same operation.
19. The method of claim 14 wherein the conductive element is a laminate having a conductive layer and a masking layer and wherein the method further includes orienting the conductive layer towards the outercover and orienting the masking layer towards the liner.
20. The method of claim 14 further comprising bonding the outercover and the liner at bond points that do not include the conductive element in the same operation as the exposing step.
