A composite liquid-retentive substrate for a hygiene article comprises a base layer of first liquid-absorptive material. The base layer having a posterior end and a diametrically opposed anterior end interconnected by an intermediate tapered region. The posterior end has opposing posterior corners and the anterior end has opposing anterior corners. A posterior liquid-flow abutment comprising second absorptive material is disposed substantially around a perimeter of the posterior end. At least one anterior liquid-flow abutment comprising second absorptive material is disposed proximate one of the anterior corners of the anterior end.

Human wearable and detachable incontinence device
20170202714 · 2017-07-20 ·

A detachable urine flow collection device that integrates with a disposable nonwoven or underwear garment worn by a human male or female. The incontinence device fits through an opening in the disposable nonwoven or underwear garment. The incontinence device is ellipsoid in shape and will be in direct and intimate contact with the users' genitals. This design allows the incontinence device to collect urine when the user urinates in different body positions. The main purpose of the incontinence devise is to channel this urine and liquid away from contact with the user and their skin as the constant contact of the liquid and urine is harmful. The channeling of urine and liquid away from the users skin is accomplished by the design of the incontinence device and the combinations of nonwoven materials that direct, move and store the urine and liquid in the device.

Disposable absorbent article

A disposable absorbent undergarment is disclosed. It includes an absorbent assembly comprising a core formed of a synthetic tow or of synthetic nonwoven layers and having first section comprising a slow acting but high absorption capacity SAP and a second section comprising a fast acting but lower absorption capacity SAP, all of which is wrapped in a wrapper to hold the SAP in place. The absorbent assembly may be quilted and corrugated. The undergarment also includes releasably securable fasteners to enable it to be readily removed and a suspension system to ensure that the garment fits properly and doesn't leak even when holding a large amount of exudate. Odor removal/masking and treatment features may be provided. It addition the undergarment may include a wetness indicator.

In particular the present invention concerns, An absorbent article such as a diaper or training pant, the absorbent article having a front edge and a rear edge, a longitudinal axis extending in a longitudinal direction of the article, the article having a length L as measured along the longitudinal axis from the front edge to the back edge, the absorbent article having an absorbent core including a first core layer and a second core layer.

Absorbent articles having channel-forming areas and wetness indicator
12226292 · 2025-02-18 · ·

An absorbent article comprising an absorbent core having a longitudinally extending channel-forming area and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid a channel is formed along the area substantially free of absorbent material.

ABSORBENT CORES HAVING MATERIAL FREE AREAS
20170135870 · 2017-05-18 ·

An absorbent core for use in an absorbent article is provided and comprises a core wrap enclosing an absorbent material, the absorbent material comprising superabsorbent polymer particles. The core wrap comprises a top side and a bottom side. The absorbent core comprises one or more area(s) substantially free of absorbent material through which the top side of the core wrap is attached to the bottom side of the core wrap (i.e. core wrap bond(s)), so that when the absorbent material swells, the core wrap forms one or more channel(s) along the area(s) substantially free of absorbent material. The superabsorbent polymer particles have a value of Effective Capacity (EFFC) of at least 27 g/g. The Effective Capacity (EFFC) is calculated via the formula below: EFFC=(CRC+AAP)/2. The Centrifuge Retention Capacity (CRC) is measured according to the Centrifuge Retention Capacity (CRC) test method and the Absorption Against Pressure (AAP) is measured according to the Absorption Against Pressure (AAP) test method. The superabsorbent polymer particles have a bulk density of at least 0.5 g/ml according to the Bulk Density Test Method.
