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: Absorbent articles such as diapers, incontinent briefs, training pants, diaper holders and liners, and the like, designed to provide improved fit and comfort for the wearer while adequately containing body exudates. The absorbent article includes an absorbent core designed so as to retain low levels of fluid in the crotch region, relative to the other core regions, even when the core absorbs significant amounts of fluid during use. To achieve this, the absorbent core is designed such that fluid is moved substantially from the crotch region to the front and/or rear ends of the article. The absorbent core has a non-removable absorbent core component in the crotch region and removable absorbent core components in the front or rear regions of the article.

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: Various stiffness characteristics of removable and replaceable absorbent core components used with disposable absorbent articles are disclosed. The replaceable core component can be constructed with bending stiffness characteristics making it easier to install in a diaper chassis. In other instances, a relatively stiff insertion tool may also be used to engage a relatively flexible replaceable core component to aid with insertion of the replacaeable core component into the diaper chassis. Aspects of the present disclosure involve replaceable core components alone or in combination with insertion tools having bending stiffness characteristics that reduce the likelihood of buckling and/or folding while installing the replaceable core component into the diaper chassis. The present disclosure also provides methods for testing replaceable core components and/or insertion tools to evaluate the bending stiffness characteristics associated therewith.

Abstract: A disposable absorbent article suitable for absorbing and retaining aqueous body fluids includes a backsheet that is substantially liquid impervious except at a discontinuity therein and an absorbent core between the backsheet and a topsheet. The absorbent core includes a non-removable component and a removable and replaceable component in fluid communication with the non-removable component. Access for the removal and replacement of the removable component is provided by the discontinuity in the backsheet. The replaceable absorbent core component may be removed and a like component may be substituted in place of the removed component without removal of the absorbent article from the wearer.

Abstract: Disclosed are absorbent cores for inclusion in articles such as diapers, incontinent briefs, training pants, diaper holders and liners, feminine hygiene garments, and the like, designed to provide improved fit and comfort for the wearer while adequately containing body exudates. The absorbent core is designed so as to retain low levels of fluid in the crotch region, relative to the other core regions, even when the core absorbs significant amounts of fluid during use. To achieve this, the absorbent core is designed such that fluid is moved substantially from the crotch region to the front and/or rear ends of the article. In particular, the absorbent core comprises in its crotch region a material having significant vertical wicking absorbent capacities. The absorbent core also preferably comprises a non-removable absorbent core component in the crotch region, and removable absorbent core components in the front or rear regions of the article.

Abstract: The present invention is a Liquid transport member with significantly improved liquid handling capability, which has at least one bulk region and a wall region that completely circumscribes said bulk region, and which comprises a port region, whereby the bulk region has an average fluid permeability kb which is higher than the average fluid permeability kp of the port regions.

Abstract: Disclosed are thin until wet materials that are suitable for use as acquisition members for absorbent articles (e.g., diapers, catamenial products, and adult incontinence devices). Preferred materials according to the present invention are either: 1) fibrous assemblies that utilize wet strength means to stabilize the material or 2) compressed regenerated cellulosic sponges so that, when the material is saturated with an aqueous fluid, it has an expanded wet density of between about 0.04 grams/cm3 and about 0.4 grams/cm3 and an expanded capillary desorption height of less than about 25 cm and a temporary binding means that helps maintain the material at a compressed dry density between about 0.06 grams/cm3 and about 1.2 grams/cm3 until the material is exposed to an aqueous fluid. The ratio of the compressed dry density to the expanded wet density is also greater than about 1.5:1. A suitable process for making the materials and absorbent structures using the materials are also disclosed.
