Fastener for an absorbent article
View Patent ↗An absorbent article includes front and rear portions and a fastener for connecting side edges of the front and rear portions. The fastener includes a grasping element attached to an outer surface of the fastener to provide for grasping by the wearer or caregiver. The grasping element may be formed of flexible material and may have a variety of configurations, including a tube, a flange, a tunnel or a pocket.
1. An absorbent article comprising:
a moisture-impervious outer layer;
an inner layer substantially co-extensive with the outer layer;
a filler interposed between the inner layer and the outer layer;
a rear portion having a rear side panel with a longitudinally extending side edge, the rear portion comprising a fastener attached to the rear side panel; and
a front portion comprising a fastener attachment area on an outside surface of the front portion, wherein the attachment area is adapted to engage the fastener;
wherein the fastener comprises:
a first portion that overlaps the rear side panel of the rear portion;
a second portion that extends laterally beyond the longitudinally extending side edge, the second portion having a length that extends in a lateral direction and a width perpendicular to the length and further having an upper surface and a lower surface;
a grasping element comprising a tube having an opening at a first end and an opening at a second end that extends laterally along the second portion upper surface, wherein the tube is folded flat against the second portion upper surface prior to use and a user inserts a finger into the tube to grip the grasping element to release the fastener; and
an attachment zone where a sidewall of the tube is attached to the second portion upper surface, wherein the attachment zone is narrower than both a diameter of the tube and the width of the second portion.
2. The absorbent article of claim 1 , wherein the grasping element comprises a flexible material.
3. The absorbent article of claim 2 , wherein the flexible material comprises nonwoven material.
4. The absorbent article of claim 2 , wherein the flexible material comprises an elastomeric material.
5. The absorbent article of claim 2 , wherein the flexible material comprises a polymer film.
6. The absorbent article of claim 1 , wherein the tube comprises an axis extending along the center of the tube, and the tube axis is generally parallel to the length of the fastener second portion.
7. The absorbent article of claim 1 , wherein the fastener attachment zone comprises an adhesive.
8. The absorbent article of claim 1 , wherein the fastener attachment zone comprises an ultrasonic bond.
9. The absorbent article of claim 1 , wherein the fastener attachment zone comprises a heat and pressure bond.
10. An absorbent article comprising:
a moisture-impervious outer layer;
an inner layer substantially co-extensive with the outer layer;
a filler interposed between the inner layer and the outer layer;
a rear portion having a rear side panel with a longitudinally extending side edge;
a fastener attached to the rear side panel and having a length that extends in a lateral direction and a width perpendicular to the length, the fastener comprising:
a base layer having an outer surface that faces away from the wearer when the article is in use and an inner surface that faces toward the wearer when the article is in use;
an engagement element attached to the inner surface of the base layer at a first attachment area; and
a grasping element attached to the outer surface of the base layer at a second attachment area, wherein the second attachment area overlaps with the first attachment area; and
a front portion comprising a fastener attachment area on an outside surface of the front portion, wherein the attachment area is adapted to engage the fastener, and
wherein the grasping element comprises:
a tube having an opening at a first end and an opening at a second end that extends laterally along the base layer outer surface, wherein the tube is folded flat against the base layer outer surface prior to use and a user inserts a finger into the tube to grip the grasping element to release the fastener; and
an attachment zone, wherein a sidewall of the tube is attached to the base layer outer surface and wherein the attachment zone is narrower than both a diameter of the tube and the width of the base layer.
11. The absorbent article of claim 10 , wherein the engagement element comprises a hook portion of a hook-and-loop fastener.
12. The absorbent article of claim 11 , wherein the front portion fastener attachment area comprises a loop portion of a hook-and-loop fastener.
13. An absorbent article comprising:
a moisture-impervious outer layer;
an inner layer substantially co-extensive with the outer layer;
a filler interposed between the inner layer and the outer layer;
a rear portion having a rear side panel with a longitudinally extending side edge;
a fastener attached to the rear side panel, the fastener comprising:
a base layer having an outer surface that faces away from the wearer when the article is in use, an inner surface that faces toward the wearer when the article is in use;
an engagement element attached to the inner surface of the base layer; and
a grasping element attached to the outer surface of the base layer and forming an enclosed area; and
a front portion comprising a fastener attachment area on an outside surface of the front portion, wherein the attachment area is adapted to engage the fastener, and
wherein the grasping element comprises:
a tube having an opening at a first end and an opening at a second end that extends laterally along the base layer outer surface, wherein the tube is folded flat against the base layer outer surface prior to use and a user inserts a finger into the tube to grip the grasping element to release the fastener; and
an attachment zone, wherein a sidewall of the tube is attached to the base layer outer surface and wherein the attachment zone is narrower than both a diameter of the tube and the width of the base layer.
