Embodiment Construction

[0052] Many current pant-like absorbent article garments are formed using prelaminated elastomeric materials, which typically include one or more elastic elements sandwiched between nonwoven layers. Such pre-laminated elastomeric materials are rolled into jumbo rolls which are then unrolled into a continuous process for forming pant-like absorbent articles. In such processes, it is generally not possible to modify the individual layers of pre-laminated elastomeric material in specific ways that allow for superior chassis structures and reduced manufacturing costs. For example, each layer of pre-laminated elastomeric material typically has the same size, especially in the longitudinal direction, and it can be very difficult to vary this longitudinal length of each layer in a continuous process for forming pant-like absorbent articles of.

[0053] The present disclosure details absorbent article garment constructions that can be formed by a continuous process wherein the lamina...

Abstract

Pant-like absorbent articles having improved chassis structures are disclosed. One pant-like garment comprises a front panel comprising a front garment-side layer, a front bodyside layer, and front elastic members therebetween, and a rear panel comprising a rear garment-side layer, a rear bodyside layer, and rear elastic members between the rear garment-side layer and the rear bodyside layer, a portion of the rear elastic members proximate a rear waist end edge are being uncovered by one of the rear garment-side layer and the rear bodyside layer. The garment may further comprise a rear secondary elastic member disposed overlapping the uncovered portion of the rear elastic members, and wherein one of the rear garment-side layer and the rear bodyside layer is folded over the rear panel secondary elastic member and overlaps the other one of the rear garment-side layer and the rear bodyside layer.

Description

technical field [0001] The present disclosure relates to absorbent articles, and more particularly to absorbent articles having improved chassis structures. Background technique [0002] People rely on disposable absorbent products in their daily lives, including articles such as adult incontinence products, enuresis pants, training pants, and diapers. Many manufacturers strive to better meet the needs of users for such products. For example, the fit, fit, and leak protection of many products need to be further improved. For certain products such as adult incontinence briefs and enuresis pants, it is important that the garment feels as much like "regular" underwear as possible to facilitate improving the normal feel of the wearer suffering from incontinence or enuresis. Many conventional pant-like, pull-on absorbent garments currently on the market employ a product chassis that includes an elastic material (or materials) sandwiched between two layers of nonwoven fabric, wh...
