The absorbent article is an absorbent article covering a crotch portion of a wearer from an abdominal side to a back side with a sheet-like main body, the absorbent article including: the main body including an abdominal side edge, a back side edge, pair of crotch side edges extending between the abdominal side edge and the back side edge, and an absorbent region in which an absorbent is disposed; a pair of restraint portions provided on the main body along the pair of crotch side edges, and configured to suppress leakage of a target object from the absorbent region; and a bonding member in a strip shape provided to the main body on a side of at least one of the abdominal side edge and the back side edge, wherein the bonding member is provided extending between the pair of restraint portions, and both ends of the bonding member are disposed between the restraint portions and the main body at one end side of the restraint portion in a longitudinal direction.
LAMINATE(S) COMPRISING BEAMED ELASTICS AND ABSORBENT ARTICLE(S) COMPRISING SAID LAMINATE(S)
The present disclosure relates to one or a combination of an absorbent article's chassis, inner leg cuffs, outer leg cuffs, ear panels, side panels, waistbands, and belts that may comprise one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or very fine (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand method below) under the elastics, while providing adequate modulus of (between about 2 gf/mm and 15 gf/mm) to make the article easy to apply and to comfortably maintain the article in place on the wearer, even with a loaded core (holding at least 50 mls of liquid), to provide for the advantages described above.
DISPOSABLE ABSORBENT ARTICLES HAVING CUFFS OF IMPROVED STRETCH LAMINATE STRUCTURE
An absorbent article having longitudinal cuffs of improved structure is disclosed. The improved cuffs may be elasticized by a plurality of elastic strands that are substantially greater in number, closer in spacing, lower in pre-strain, and lower in decitex, or any combination of these, as compared with those in conventional articles. This combination of features results in ruffles or gathers of cuff material joined to the elastic strands that are substantially greater in machine-direction frequency and substantially lesser in z-direction amplitude, than those in conventional articles. As a result, the cuff structure lies more closely and evenly against the wearer's skin, has an improved, more cloth-like appearance, provides improved gasketing, and provides improved wearer comfort, as compared with cuff structures in conventional articles. A method for manufacturing articles with such cuff structures, utilizing a warp beam as a supply mechanism, is also disclosed.
LENGTH-TO-WAIST SILHOUETTE(S) OF ABSORBENT ARTICLE(S) COMPRISING BEAMED ELASTICS
The present disclosure relates to absorbent articles comprising belts comprising one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or low decitex (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand Test in the Method below) under the elastics, while providing adequate Section-Modulus of (between about 2 gf/mm and 15 gf/mm), resulting in a Product Length-to-Waist Silhouette that is within from about −0.3 to about 0.3 of the Target Body Length-to-Waist Silhouette to make the article conform better to the body of the wearer at a lower Pressure-Under-Strand, even with a loaded core (holding at least 50 mls of liquid), to provide for the advantages described above.
TAPE-TYPE DISPOSABLE DIAPER
A tape-type disposable diaper in which a lower edge of a non-connecting portion of a connecting tape has a shape in which a tangent angle θ decreases without having a critical point and an inflection point from a distal end far from a base portion of the connecting tape to a proximal end close to the base portion. A shorter one of a distance in a width direction between the proximal end of the lower edge of the non-connecting portion and the distal end of the lower edge of the non-connecting portion and a distance in a front-back direction between the proximal end of the lower edge of the non-connecting portion and the distal end of the lower edge of the non-connecting portion is set to r, the entire lower edge of the non-connecting portion exclusively includes a part having a radius of curvature of 0.8r or more.
Disposable absorbent article and absorbent core composite or construction for incorporation therewith, components therefor or thereof, and systems, apparatus and methods of making the same
Improved absorbent core components including multiple layers configured to enhance fluid handling properties. The layers include absorbent material layers, with or without absorbent material-free lanes. The layers also include nonwoven layers, including air-through nonwovens, bulkified nonwovens, slitted nonwovens, and bulky nonwovens.
METHODS AND APPARATUSES FOR MAKING ELASTOMERIC LAMINATES WITH ELASTIC STRANDS UNWOUND FROM BEAMS
The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. A first beam is rotated to unwind a first plurality of elastic strands from the first beam in the machine direction. The first plurality of elastic strands are positioned between the first substrate and the second substrate to form the elastomeric laminate. Before the first plurality of elastic strands are completely unwound from the first beam, a second beam is rotated to unwind the second plurality of elastic strands from the second beam. Subsequently, the advancement of the first plurality of elastic strands from the first beam is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first beam to a subsequently utilized elastic material drawn from the second beam.
ABSORBENT ARTICLE(S) CHASSIS COMPRISING BEAMED ELASTICS
The present disclosure relates to absorbent article's chassis that may comprise one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or low decitex (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand Test in the Method below) under the elastics. The elastics in the chassis may be oriented parallel or transverse to the longitudinal axis.
Methods and Apparatuses for Making Elastomeric Laminates with Elastic Strands Unwound from Spools on Surface Unwinders
The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. First spools are rotated to unwind first elastic strands from a first unwinder in a machine direction. The first elastic strands are positioned between the first substrate and the second substrate to form an elastomeric laminate. Before the first elastic strands are completely unwound from the rotating first spools, second spools are rotated to unwind second elastic strands from a second unwinder. Subsequently, the advancement of the first elastic strands from the first unwinder is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first spools to a subsequently utilized elastic material drawn from the second spools.
Absorbent article
An absorbent article includes: a front waist portion extending along the lateral direction; a back waist portion extending along the lateral direction; and a crotch portion provided between the front waist portion and the back waist portion. A lateral end portion of the back waist portion on a one side and a lateral end portion of the front waist portion on the one side are joined by a first joining portion. The back waist portion has a fastening portion provided on another side in the lateral direction, and the fastening portion is capable of being fastened to the front waist portion when putting on the absorbent article. The front waist portion has a target region to which the fastening portion is to be fastened, and a lateral end of the target region on the one side is located on the one side relative to a lateral central position of the crotch portion.
