ABSORBENT ARTICLE WITH LEG GASKETING SYSTEM
Disclosed is a pant type absorbent article comprising a core chassis and a leg gasketing system comprising a pair of wearer facing cuff regions comprising an inner cuff sealing and inner cuff free edge positioned inward from the inner cuff sealing, and an inner cuff elastic element is disposed adjacent the inner cuff free edge; a pair of garment facing cuff regions, and a pair of outer cuff elastic elements disposed on wearer facing cuff regions or garment facing cuff regions, each outer cuff elastic element disposed so as to superpose the core side regions and so as to superpose the inner cuff sealings or outward thereof; and wherein the front belt and the absorbent body is joined in a manner such that the front longitudinal end of the outer cuff elastic element in active elasticity superposes the front belt and left unjoined to the front belt.
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.
APPARATUSES AND METHODS FOR MAKING ABSORBENT ARTICLES WITH ELASTOMERIC LAMINATES
The present disclosure relates to methods and apparatuses for making elastomeric laminates with deactivated regions that may be used as components of absorbent articles. The methods and apparatuses may be configured with a pattern roll and a pressing surface adjacent the pattern roll. The pattern roll may include a bonding surface and a protuberance. As the pattern roll rotates, first and second substrates are welded together between the bonding surface and the pressing surface to create bonds between the first and second substrates. As the pattern roll continues to rotate, the first and second substrates and one or more stretched elastic strands are compressed between the pressing surface and the protuberance to sever the one or more stretched elastic strands to create deactivated regions in the elastomeric laminate. The processes and apparatuses may be configured to help prevent ends of the severed elastic strands from retracting in an uncontrolled fashion.
Disposable diaper
A disposable diaper 1 has an elasticized leg cuff 10 on each longitudinally extending, lateral side of the crotch portion C. The elasticized leg cuff 10 includes an elastic member fixing sheet 5, an elastic member 6, an inner sheet 31, and an outer sheet 32 in order from the skin facing side. The inner sheet 31 and the outer sheet 32 are bonded to each other via a plurality of longitudinally extending and laterally spaced bonds 7. The elastic member 6 is located between the elastic member fixing sheet 5 and the inner sheet 31 and arranged at a location that does not overlap the bonds 7.
Trunks type disposable diaper
In a trunks-type disposable diaper in which a front around-leg elastic member and a back around-leg elastic member are attached on both sides in a width direction of an intermediate region in a region between an edge of one leg opening and an edge of the other leg opening in a pattern in which at least one front around-leg elastic member and at least one back around-leg elastic member cross each other, the above-described problem is solved by providing an inner member bonded portion that is a region bonding an outer member and an inner member only further to the center side in the width direction than a crossing position between the front around-leg elastic member and the back around-leg elastic member on both sides in the width direction in the intermediate region.
ABSORBENT ARTICLE
An absorbent article (10) has a front region (20), a back region (30), and a crotch region (40) extending between and connecting the front region (20) and the back region (30). The absorbent article (10) can have non-linear leg edges (82, 84) extending between and connecting the front region (20) and the back region (30). The absorbent article (10) can have an absorbent article (10) narrowest width (80) positioned between the waist edge (22) of the front region (20) and the transverse axis (14) of the absorbent article (10). A non-linear leg elastic (140) can extend from one side edge (34) of the back region (30) to another side edge (36) of the back region (30) and can have an apex (142) located between the absorbent article (10) narrowest width (80) and the transverse axis (14).
ABSORBENT ARTICLES WITH CURVED ELASTICIZED LAMINATES
Absorbent articles having curved elasticized laminates and apparatuses and methods for forming such articles are disclosed. In one embodiment a method of forming an article may comprise moving absorbent assemblies and elasticized laminates in the machine direction. The method may further comprise oscillating the elasticized laminates in the cross-machine direction to impart a curvature, bonding the elasticized laminates to the absorbent assemblies while maintaining the imparted curvature such that at least a portion of the elasticized laminates are disposed outboard of longitudinal side edges of the absorbent assemblies, and finally separating the absorbent assemblies into individual absorbent articles, where the elasticized laminates extend in a curving manner throughout the absorbent articles.
Apparatuses and methods for making absorbent articles with elastomeric laminates
The present disclosure relates to methods and apparatuses for making elastomeric laminates with deactivated regions that may be used as components of absorbent articles. The methods and apparatuses may be configured with a pattern roll and a pressing surface adjacent the pattern roll. The pattern roll may include a bonding surface and a protuberance. As the pattern roll rotates, first and second substrates are welded together between the bonding surface and the pressing surface to create bonds between the first and second substrates. As the pattern roll continues to rotate, the first and second substrates and one or more stretched elastic strands are compressed between the pressing surface and the protuberance to sever the one or more stretched elastic strands to create deactivated regions in the elastomeric laminate. The processes and apparatuses may be configured to help prevent ends of the severed elastic strands from retracting in an uncontrolled fashion.
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.
