Abstract

An absorbent article embodied as a disposable diaper construction has been particularly configured for improved fit and comfort by providing an absorbent structure attached in a substantially free-floating suspended manner within the diaper. In the illustrated embodiments, the diaper includes an outer cover or back sheet and an absorbent structure or core which is supported within the outer cover by a supporting member which extends along a side of the absorbent structure and includes opposite ends which are secured to the outer cover. The supporting member suspends and supports the absorbent structure for substantially independent movement with respect to the outer cover so that the absorbent structure can conform to the wearer during use thus improving the fit and comfort to the wearer as well as inhibiting leakage from the diaper.

Claims

1. An absorbent article, comprising:

a liquid permeable outer cover having a front section and a rear section;

a substantially non-extensible elongate absorbent structure having a front end, a rear end, top and bottom surfaces and opposite side surfaces, said absorbent structure being positioned within said outer cover with said front and rear ends of said absorbent structure extending into said front and rear sections of said outer cover, respectively, said absorbent structure including a barrier layer on at least one surface thereof facing said outer cover;

at least one elastic element having opposite ends joined to said front and rear sections of said outer cover, respectively, for suspending and supporting said absorbent structure for substantially independent movement with respect to said outer cover and for enabling substantially independent longitudinal movement of said at least one elastic element with respect to said absorbent structure and said outer cover except at said opposite joined ends so that said absorbent structure can conform to a body of a wearer during use; and

a channel positioned on one surface of said absorbent structure and extending between said front and rear ends thereof, said at least one elastic element being positioned within said channel for laterally constraining said at least one elastic element with respect to said absorbent structure and enabling said substantially independent longitudinal movement of said at least one elastic element with respect to said absorbent structure and said outer cover and enabling said absorbent structure to conform to the body of the wearer during use,

wherein said channel is formed by a sheet of liquid permeable material and including means for attaching said sheet with respect to said absorbent structure for enabling said substantially independent longitudinal movement of said at least one elastic element,

wherein said sheet completely surrounds said absorbent structure and said at least one elastic element, and includes first and second opposite longitudinal ends connected to said front and rear sections, respectively, of said outer cover.

2. An absorbent article in accordance with claim 1 wherein said at least one elastic element includes a plurality of elastic elements and said sheet is secured to said absorbent structure between each elastic element to provide a plurality of channels, one each for a respective elastic element.
