Abstract:
PROBLEM TO BE SOLVED: To provide an absorptive article which has exchangeable absorptive core components in a manner that the absorptive core components can be replaced without the needs of removal of the absorptive article from an wearer. SOLUTION: The disposable absorptive article includes a chassis, a non-removable absorptive core component which is disposed in a crotch region 66 of the chassis, and a replaceable absorptive core component which is disposed in a capillary liquid communication with the non-removable absorptive core component. The replaceable absorptive core component may also be removed to be replaced by a fresh component of the similar kind without removal of the disposable article from a wearer. The exchangeable absorptive core component may also be disposed inside an openable chassis pocket which is provided by an aperture 44 in a back sheet 62, an openable end of an external pocket, or an openable end of an internal pocket formed in an area of a waist end edge where the back sheet 62 and the top sheet 61 may be separated.

Abstract:
PROBLEM TO BE SOLVED: To provide an absorbent article which can remove or replace an absorbent core element without discarding the absorbent article from a wearer. SOLUTION: An absorbent article is for obtaining a body fluid from a wearer. The article has a perimeter which defines its external perimeter. A top sheet and a backsheet which is fixed on the topsheet on the perimeter are included. The absorbent article has at least one removable absorbent core element which is arranged between the topsheet and the backsheet. The topsheet and the backsheet form an opening in a surrounding predetermined area and are separated mutually. Also, they can be sealed again. The removable absorbent core element can be removed from the absorbent article through the opening. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide an absorptive article having a removable element. SOLUTION: This absorptive article for acquiring humor from a wearing person is provided with a fluid impermeable back sheet and at least one removable absorptive core element arranged adjoining the fluid impermeable back sheet. The fluid impermeable back sheet comprises a means for providing an approach to the removable absorptive core element through the back sheet. The removable absorptive core element is thereby removed from the absorptive article through the back sheet.
Abstract:
The present invention is a liquid transport member with significantly improved liquid handling capability, which has at least one bulk or inner region with a high average permeability, completely circumscribed by a wall region. The wall region further comprises at least one port region with a lower permeability than the inner region, and with a ratio of its permeability to its thickness of at least 10 m.
Abstract:
Absorbent articles are provided having a bolstering waist feature. In its preferred embodiment, the bolstering waist feature expands upon exposure to aqueous body liquids effectively tightening the diaper by stretching of the waist regions of the absorbent article. There is a resulting increase in the contractive forces in the band of lateral tension in the waist regions of the absorbent article with a corresponding reduction in the risk of waist leakage. The bolstering waist feature further provides a member resisting longitudinal bending in the waist regions of the absorbent article, particularly adjacent to a wearer's belly. This member can also act as a 'strut' resisting the forces, such as those due to gravity, which tend to cause an absorbent article to slide downward. The absorbent article is additionally provided with an absorbent core comprising at least a redistribution component that is preferably capable of redistributing aqueous body liquids from the crotch region to the waist regions of the absorbent article. The redistribution component is in effective fluid communication with the bolstering waist feature.
Abstract:
A disposable absorbent article adapted to be worn about a lower torso of a human body and having a chassis, a non-removable absorbent core component disposed in a crotch region of the chassis, and a replaceable absorbent core component disposed in capillary liquid communication with the non-removable absorbent core component. The replaceable absorbent core component may be removed and a like component may be substituted in place of the removed component without the removal of the absorbent article from the wearer. The replaceable absorbent core component may be disposed inside an openable chassis pocket, with access for its removal and replacement provided by an aperture in a backsheet, an openable end of an external pocket, or an openable end of an internal pocket formed at an area of a waist end edge where the backsheet and a topsheet may be separated. Additional replaceable absorbent core components may also be incorporated.
Abstract:
Aspects of the present disclosure involve fluid partitioning characteristics of removable and replaceable absorbent core components used with disposable absorbent articles. A replaceable core component can be constructed to have fluid partitioning characteristics that reduce the need to replace the chassis of the absorbent article as often as well as providing comfort to the wearer. The more fluid a replaceable core component absorbs and extracts from the chassis results in correspondingly less fluid that will remain in the chassis when the replaceable core component is removed and replaced. The ability of a replaceable core component to absorb and extract fluid from the chassis of an absorbent article may be evaluated by measuring the fluid partitioning values of the replaceable core component and absorbent article. Fluid partitioning values provide an indication of the percentage of a quantity of fluid discharged into the chassis that is absorbed by the replaceable core component.
Abstract:
Disclosed are absorbent articles, such as diapers, for the management of incontinence. Such articles utilize in their absorbent cores (50) a fluid acquisition/distribution component (51) and a fluid storage/redistribution component (52) maintained in fluid communication with the acquisition/distribution component. The fluid acquisition/distribution component (51) can be any porous hydrophilic, e.g., fibrous or foam-based material which will provide an initial Fluid Acquisition Rate of at least 2 ml of synthetic urine per second and will also preferably provide a 30-minute Vertical Wicking Height of at least 2 cm. The fluid storage/redistribution component (52) comprises a hydrophilic, flexible, open-celled polymeric foam having a free absorbent capacity of at least about 12 ml of synthetic urine per gram of dry foam and an absorbent capacity under a 5.1 kPa confining pressure which is at least 5 % of this free capacity. Preferred fluid acquisition/distribution component materials comprise chemically stiffened, twisted, curled cellulosic fibers. Preferred fluid storage/redistribution component materials comprise absorbent foams prepared by polymerizing a high internal phase emulsion (HIPE).
Abstract:
It is one aspect of the present invention to provide a liquid handling member which combines high liquid suction capability with a high permeability. It is another aspect of the present invention to provide liquid handling member which combines a high liquid suction capability with a fast 80 percent capacity absorption time. The present invention further provides devices for handling body liquids which comprise the liquid handling member of the present invention such as for example baby diapers, training pants, sanitary napkins, adult incontinence devices, bed mats, and the like.
Abstract:
An absorbent structure comprising a lower acquisition component having an original dimension and positioned to receive body exudates, and a storage component interposed between the wearer and the lower acquisition component which has a recovery from wet compression and an ability to recover from wet compression. The lower acquisition component can also vertically wick body exudates. The components work together to partition exudates from the lower acquisition component. Also, the lower acquisition component can have a resistance to compression deflection.
