Pant structure with efficiently manufactured and aesthetically pleasing rear leg profile
A disposable absorbent pant having a front belt portion and a rear belt portion is disclosed. The front and rear belt portions are joined at side seams and the rear belt portion has a greater length than the front belt portion. A lower edge of the rear belt portion forms at least in part edges of left and right leg openings to the rear of the side seams. The rear belt portion includes first and second layers of nonwoven web material sandwiching a plurality of laterally extending and laterally pre-strained elastic strands, disposed below the side seams. A first of the plurality of elastic strands differs from a second of the plurality of elastic strands by one or more of amount of pre-strain, tensile modulus, decitex, and combinations thereof.
Methods of making laminates for absorbent articles
A method of making a laminate for an absorbent article is provided. The laminate comprises elastic elements disposed at least partially intermediate two substrates. The first substrate has a primary fiber bond pattern formed therein and comprising a plurality of primary fiber bonds. The method comprises forming densified regions in the first substrate. A perimeter of each of the densified regions is larger than a perimeter of each of the primary fiber bonds. The densified regions together form a pattern of densified regions in the first substrate. The method comprises adhesively attaching the elastic elements to the first substrate, joining the second substrate to the first substrate or to some of the elastic elements, and forming a plurality of rugosities in the first substrate by allowing the elastic elements to at least partially contract. The frequency and amplitude ranges of the rugosities result from the pattern of the densified regions.
RECLOSABLE UNDERWEAR-TYPE DISPOSABLE ARTICLE FOR WEARING AND MANUFACTURING METHOD THEREFOR
While in an unused folded state of a worn article, flaps are engaged with second touch fasteners in a protruding end portion via first touch fasteners, and the flaps are folded so that the protruding end portion comes closer to a proximal end portion, and while in a worn state in which the worn article is used, the flaps can be developed so that the first touch fasteners of the protruding end portion can oppose and engage with the second touch fasteners.
PANT STRUCTURE WITH EFFICIENTLY MANUFACTURED AND AESTHETICALLY PLEASING REAR LEG PROFILE
A disposable absorbent pant having a front belt portion and a rear belt portion is disclosed. The front and rear belt portions are joined at side seams and the rear belt portion has a greater length than the front belt portion. A lower edge of the rear belt portion forms at least in part edges of left and right leg openings to the rear of the side seams. The rear belt portion includes first and second layers of nonwoven web material sandwiching a plurality of laterally extending and laterally pre-strained elastic strands, disposed below the side seams. A first of the plurality of elastic strands differs from a second of the plurality of elastic strands by one or more of amount of pre-strain, tensile modulus, decitex, and combinations thereof.
Absorbent articles having texture zones forming background patterns and macro patterns
An absorbent article comprises first and second substrates and one or more elastic elements disposed at least partially intermediate the substrates. The second substrate is attached to the first substrate and/or to portions of the elastic elements. The absorbent article comprises an adhesive having a first and second pattern of elements disposed on first substrate, and first and second texture zones. The first texture zone comprises a first portion of the substrates, a first portion of the elastic elements, and the first pattern of elements of the adhesive and forms a background pattern in the first portion of the substrates. The second texture zone comprises a second portion of the substrates, a second portion of the one or more elastic elements, and the second pattern of elements of the adhesive and forms a macro pattern in the second portion of the substrates.
ADULT DISPOSABLE ABSORBENT ARTICLES AND ARRAYS OF ABSORBENT ARTICLES COMPRISING IMPROVED DESIGNS
An array of packages comprising two or more different sizes of absorbent articles, the array comprising first, second, and third packages comprising first, second, and third absorbent articles having at least first and second sizes. The first, second, and third articles may have an insert length to rise ratio greater than 60%. And, the first, second, and third packages may comprise the same brand name and sub-brand name. And, the first, second, and third absorbent articles may have identical or substantially identical chassis.
ABSORBENT ARTICLE
An absorbent article according to the present invention having a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber disposed between the top sheet and the back sheet includes a first recessed portion configured in a top surface of the absorber facing the top sheet and extending along a first direction and a second recessed portion configured in the top surface of the absorber facing the top sheet so as to intersect the first recessed portion, the second recessed portion extending along a second direction different from the first direction. The first recessed portion and the second recessed portion each have a first area having a shallow depth from the top surface of the absorber to a bottom surface of the first area and a second area having a deeper depth than the first area.
METHOD FOR FORMING STRETCHABLE STRUCTURE FOR ABSORBENT ARTICLE AND STRETCHABLE STRUCTURE FOR ABSORBENT ARTICLE
The present invention is intended to prevent cutting of the resilient and elastic members by a welding process. The foregoing issue is solved by passing a first sheet layer, a second sheet layer, and elongated resilient and elastic members continuously disposed in an MD direction between the two sheet layers, between a first roll with joint convex parts provided at circumferential intervals on an outer peripheral surface and a second roll opposed to the first roll, and pressurizing and heating the first sheet layer and the second sheet layer to form sheet joined sections by welding the first sheet layer and the second sheet layer in such a manner as to cross the resilient and elastic members and have MD-direction intervals therebetween, wherein circumferentially continuous grooves are formed on a pressurization surface of the second roll, passage sections of the resilient and elastic members are pressurized and heated in positions including the grooves of the second roll, and non-passage sections of the resilient and elastic members are pressurized and heated in positions not including the grooves of the second roll.
UNDERPANTS-TYPE DISPOSABLE DIAPER
The present invention is intended to improve the dynamic fit of a crotch portion. The foregoing issue is solved in such a manner that a vertical stretchable part vertically extending and contracting in length is provided in a vertical intermediate portion of an absorber in a front body, an outer body of the front body has a portion overlapping at least the vertical stretchable part, width-direction both side sections of the portion, and a waist opening-side area of the portion and the sections, lifting elastic members having a contraction force of lifting a portion of the vertical stretchable part on a rear side of a front end toward width-direction both sides and an obliquely upward side at least when the diaper is worn are provided in the outer body of the front body on closer to lateral sides than to a width-direction intermediate portion of the absorber, and the vertical stretchable part vertically extends and contracts in length by elastic extension and contraction of the lifting elastic member.
DISPOSABLE UNDERGARMENT AND RELATED DISPOSAL METHODS
A disposable undergarment is disclosed which includes a main body having an absorbent core, a first side and a second side. The main body has a top sheet and a liquid-impermeable back sheet formed from polypropylene. The main body also has a front portion, a rear portion, and a crotch portion, and each of the front and rear portions has a top edge. The undergarment also has first and second elastic extensions each having a proximal end and a distal end. The proximal ends of the first and second extensions are ultrasonically bonded to the main body. The undergarment further has first and second attachment areas, each having a plurality of engaging elements, secured to the liquid permeable top sheet. The engaging elements engage with the first and second elastic extensions to secure the undergarment at least about 0.5 inches below said wearer's waist.
