A disposable absorbent article has a central body defining a first waist end region including a first end edge, a second waist end region spaced longitudinally from the first waist end region and including a second end edge, and a crotch region positioned therebetween. An absorbent core is situated between the end edges, and includes a plurality of elastics incorporated therewith such that the core is substantially lat-erally contracted in a narrowed region about the elastics. The absorbent core includes at least one end region that is sub-stantially non-elasticized and has a lateral width substantially wider than that of the narrowed region.

In this disposable diaper, a compound stretchable member is provided to a waist portion, and the compound stretchable member is provided with a plurality of elastic members extending in a waist direction, and an inside nonwoven fabric sheet portion and an outside nonwoven fabric sheet portion superposed so as to be joined to each other via the elastic members. The waist portion includes a first region and a second region provided continuously with or separately from the first region in a direction orthogonal to and the waist direction, and protruding parts and recessed parts of an unevenness region are provided at a first unevenness pitch in the compound stretchable member disposed in the first region along the waist direction, and are provided at a second unevenness pitch different from the first unevenness pitch in the compound stretchable member disposed in the second region.

The present application relates to an electronic wetness-sensing absorbent article and related methods. The electronic wetness-sensing absorbent article includes a flexible waterproof thin film; at least two mutually separated and insulated flexible electrodes disposed on one surface of the flexible waterproof thin film; a water-permeable braided fabric layer; and an absorbent layer disposed on the other surface of the flexible waterproof thin film, located between the flexible waterproof thin film and the water-permeable braided fabric layer, and adapted to absorb a liquid entering from the water-permeable braided fabric layer. The flexible waterproof thin film, the flexible electrodes, and the liquid contained in the absorbent layer form a non-polar variable electrolytic capacitor. The wetness state of the electronic wetness-sensing absorbent article is obtained by detecting the capacitance value of the variable electrolytic capacitor and change thereof.

An absorbent article includes a chassis having a substantially rectangular shape a first portion, a second portion and a crotch portion extending between the first and second portion, a portion of the chassis being configured to absorb fluids. The absorbent article includes a first securement portion operatively coupled to the first portion of the chassis. The absorbent article includes a second securement portion operatively coupled to the second portion of the chassis and configured to releasably attach to the first securement portion. The chassis is configured to include one of a first chassis length or a second chassis length. When the chassis includes the first length, the chassis includes a first width and the first securement portion includes a second width, and when the chassis includes the second length, the chassis includes the first width and the first securement portion includes a third width, greater than the second width.

A device for detecting a state of a diaper includes a sensor unit with a conducting unit including at least two electrodes. The electrodes are configured to detect electrical parameters of their environment. A coupling portion is disposed on at least one end side of the conducting unit and is connectable to a measuring device. The conducting unit is attached to a carrier layer. The measuring device comprises an input portion being connectable to the sensor unit, and a processor configured to receive signals corresponding to values of the electrical parameters detected by the sensor unit and to process said signals. A power control means is configured to control electrical power supplied from a power supply, and a determination means is configured to determine whether a state of a diaper has changed. A transmitting means is configured to transmit information regarding the determined state change to a receiving means.

An absorbent core for a diaper for a non-human has a total superabsorbent polymer (SAP) load. The absorbent core includes a first zone including a first absorbent section and a second absorbent section, a second zone including a third absorbent section, and a third zone including a fourth absorbent section and a fifth absorbent section. The absorbent sections each include a range of 15% to 20% of the total SAP load. The second zone is between the first zone and the third zone. The absorbent core further includes seals surrounding each of the first absorbent section, the second absorbent section, the third absorbent section, the fourth absorbent section, and the fifth absorbent section. One of the seals extends through the first zone between the first absorbent section and the second absorbent section, and another of the seals extends through the third zone between the fourth absorbent section and the fifth absorbent section.

Configurable absorbent articles are provided. The absorbent articles may comprise a topsheet, a backsheet, and an absorbent core positioned at least partially intermediate the topsheet and the backsheet. The absorbent articles may comprise a first waist region, a second waist region, a crotch region extending intermediate the first waist region and the second waist region, and an outer cover material joined to the backsheet and forming a portion of a garment-facing surface of the absorbent article. The absorbent articles may comprise a pair of leg cuffs and a fully removable fastening member. The fastening member may comprise a first fastener on a first surface of the fastening member and positioned proximate to a first end and a second fastener on the first surface and positioned proximate to a second end. The absorbent articles may also comprise a wetness guard.

An absorbent article has a front side, a back side, a longitudinal axis and includes a liquid permeable topsheet on the wearer-facing side, a liquid impermeable backsheet on the garment-facing side, and an absorbent core between the topsheet and the backsheet. The absorbent core includes a core wrap having a top side and a bottom side, an absorbent material having a deposition area between the top side and the bottom side of the core wrap, and at least two channels substantially free of absorbent material within the deposition area. In a first type of channels, the top side and the bottom side of the core wrap are bonded to each other. In a second type of channels, the top side and the bottom side of the core wrap are not bonded or are less bonded to each other than in the first type of channels.

The present disclosure relates to a diaper with removable waistbands, including a first diaper body disposed in an abdominal area, which is in front on a basis of a waist; removable waistbands, which are connected to both sides of the first diaper body, formed of a stretchable material and configured to be removable by perforated lines formed between the first diaper body and the removable waistbands; waistband Velcro portions provided at ends of the removable waistbands; a second diaper body which is connected to the first diaper body and disposed in a buttocks area, which is in rear on the basis of the waist; combination wings connected to both sides of the second diaper body; combination wing Velcro portions provided at ends of the combination wings; and wrinkle connection portions which connect the first diaper body and the second diaper body in a wrinkle manner.

An absorbent article has a front side, a back side, a longitudinal axis, a liquid permeable topsheet, a liquid impermeable backsheet and an absorbent core between the topsheet and the backsheet. The absorbent core includes a first type of channels, wherein the top side and the bottom side of the core wrap are bonded to another, and a second type of channels, wherein the top side and the bottom side of the core wrap are not bonded or are less bonded to one another in this second type of channels than in the first type of channels. The absorbent material may also include cellulose and superabsorbent particles.
