Abstract
The present invention provides a method of providing a disposable product with a contoured leg opening. In this method at least one chip is removed from at least one ear of a disposable product. The chip may be removed from an ear prior to attaching the ear to the chassis web. Alternatively, the chip may be removed from the ear after the ear is attached to the chassis web.
Claims9
A disposable product comprising:
- a front and back left wing;
- a front and back right wing;
- said front and back wings coupled at an inboard edge of said front and back wings to a chassis web carrying an absorbent core, said chassis web having a back waist edge and a front waist edge, said chassis web extending in a lengthwise direction from said back waist edge to said front waist edge, said chassis web also extending in a widthwise direction between said back left wing and said back right wing;
- a left web absent any closure mechanism and coupled to said back left wing at an outboard edge of said back left wing;
- a right web absent any closure mechanism and coupled to said back right wing at an outboard edge of said back right wing;
- a left ear coupled to said left web, said left ear coupled to a first closure mechanism along less than a lengthwise direction dimension of said left ear;
- a right ear coupled to said right web, said right ear coupled to a second closure mechanism along less than a lengthwise direction dimension of said right ear;
- said back right and left wings further comprising a back waist edge, and a leg opening facing edge;
- said left and right ears having a back waist edge;
- said chassis web having a back waist edge;
- said back right wing back waist edge and said back left wing back waist edge spaced apart from said chassis back waist edge chassis in said lengthwise direction at a first distance from said chassis web back waist edge;
- said first closure mechanism separated from said back left wing in said widthwise direction by a bonded portion between said back left ear and back left wing, and by a widthwise portion of said back left ear;
- and
- said second closure mechanism separated from said back right wing in said widthwise direction by a bonded portion between said back right ear and back right wing, and by a widthwise portion of said back right ear.

A disposable product comprising:
- a front and back left wing;
- a front and back right wing;
- said front and back wings having respective inboard edges deposited on and bonded to a chassis web carrying an absorbent core, said chassis web having a back waist edge and a front waist edge, said chassis web extending in a lengthwise direction from said back waist edge to said front waist edge, said chassis web also extending in a widthwise direction between said back left wing and said back right wing;
- a left-side panel assembly coupled to said back left wing and comprising:
- a left web having an inboard edge coupled to said back left wing and an outboard edge;
- a left ear coupled to said left web and having an inboard edge and an outboard edge;
- and
- at least one fastener coupled to said left ear closer to the outboard edge of the left ear than to the inboard edge of the left ear;
- a right-side panel assembly coupled to said back right wing and comprising:
- a right web having an inboard edge coupled to said back right wing and an outboard edge;
- a right ear coupled to said right web and having an inboard edge and an outboard edge;
- and
- at least one fastener coupled to said right ear closer to the outboard edge of the right ear than to the inboard edge of the right ear.
