Abstract

An absorbent article (10) has a front waistband portion (12), a back waistband portion (14) and an intermediate portion (16) which interconnects the front and back waistband portions. The article includes a backsheet layer (30), an absorbent retention portion (48) superposed on the backsheet layer (30), and a liquid permeable topsheet layer (28) superposed on the retention portion (48) and connected to sandwich the retention portion between the topsheet and backsheet layers. At least one elasticized side panel (58) is connected to a lateral end region (40) of the back waistband portion (14) of the article. The side panel (58) is constructed with a flap fastener (74) for interconnecting with the article to thereby form an assembled bridge flap (180), which extends about a wearer'"'"'s body and provides a bodyside surface for contacting the wearer. Article fastening means (36) are connected to the article for securing the article front waistband portion (12) to the article back waistband portion (14) to thereby encircle the wearer with the article waistband portions. Waistband-edge attaching means (112, 104) are connected to the elasticized side panel (58) for securing a longitudinally terminal waistband edge of the assembled bridge flap (180) to the front waistband portion (12) of the article.

Claims

1. An absorbent article having a front waistband portion, a back waistband portion and an intermediate portion which interconnects said front and back waistband portions, said article comprising:

a backsheet layer;

an absorbent retention portion superposed on said backsheet layer;

a liquid permeable topsheet layer superposed on said retention portion and connected to sandwich said retention portion between said topsheet and backsheet layers;

at least one elasticized side panel connected to a lateral end region of said back waistband portion of said article, said side panel having a flap fastener for interconnecting with said article back waistband portion to thereby form an assembled bridge flap, said assembled bridge flap arranged to extend about a wearer'"'"'s body and to provide a bodyside surface for contacting the wearer;

article fastening means connected to lateral end portions of said article front waistband portion for securing said lateral end portions of said article front waistband portion to regions of said article back waistband portion to thereby encircle the wearer with said article waistband portions; and

waistband-edge attaching means which extend along a longitudinally terminal waistband edge of said elasticized side panel for securing said longitudinally terminal waistband edge of said assembled bridge flap to said front waistband portion of the article to provide a liquid-resistant seal along said waistband-edge attaching means when said article waistband portions encircle the wearer.

2. An absorbent article as recited in claim 1, wherein said article includes a pair of laterally opposed, elasticized side panels connected at laterally opposed end regions of said back waistband portion of said article, said side panels having flap fasteners for interconnecting said side panels to each other about a wearer'"'"'s body to thereby form said assembled bridge flap.

3. An absorbent article as recited in claim 1, wherein said waistband edge attaching means includes an adhesive.

4. An absorbent article as recited in claim 1, wherein said waistband edge attaching means includes an interlocking mechanical attaching mechanism.

5. An absorbent article having a front waistband portion, a back waistband portion and an intermediate portion which interconnects said front and back waistband portions, said article comprising:

a backsheet layer;

an absorbent retention portion superposed on said backsheet layer;

a liquid permeable topsheet layer superposed on said retention portion and connected to sandwich said retention portion between said topsheet and backsheet layers;

at least one elasticized side panel connected to a lateral end region of said back waistband portion of said article, said side panel having a flap fastener for interconnecting with said article back waistband portion to thereby form an assembled bridge flap, said assembled bridge flap arranged to extend about a wearer'"'"'s body and to provide a bodyside surface for contacting the wearer, said at least one elasticized side panel including a foldable section which extends length-wise past a longitudinally terminal edge of said backsheet layer;

article fastening means connected to lateral end portions of said article front waistband portion for securing said lateral end portions of said article front waistband portion to regions of said article back waistband portion to thereby encircle the wearer with said article waistband portions; and

waistband-edge attaching means connected to said elasticized side panel for securing a longitudinally terminal waistband edge of said assembled bridge flap to said front waistband portion of the article when said article waistband portions encircle the wearer, said waistband-edge attaching means providing fold attaching means connected to said foldable section of said side panel for holding said foldable section in a substantially C-folded condition when said foldable section is wrapped about a laterally extending, terminal edge of said article front waistband portion.

6. An absorbent article as recited in claim 5, wherein said article includes a pair of laterally opposed, elasticized side panels connected at laterally opposed end regions of said back waistband portion of said article, each said side panel including said foldable section which extends length-wise past a longitudinally terminal edge of said backsheet layer, said side panels constructed for interconnecting with each other about a wearer'"'"'s body to thereby form said assembled bridge flap.

7. An absorbent article as recited in claim 6, wherein each said foldable section has a longitudinally extending border distance of at least about 1 cm.

8. An absorbent article as recited in claim 5, wherein said foldable section has a longitudinally extending border distance of at least about 1 cm.

9. An absorbent article as recited in claim 5, wherein said waistband-edge attaching means includes an adhesive.
