Abstract:
Absorbent articles having a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed between said topsheet and said backsheet are disclosed. The absorbent articles include a thermoplastic elastomer joined to or disposed in a stretch zone on at least one component or region of the absorbent article to impart an elastic resistance that provides sizing or shaping capabilities to the article. The absorbent article can be in the form of diapers, pull-on diapers, training pants, sanitary napkins, wipes, bibs, incontinence briefs or inserts.
Abstract:
A disposable absorbent article is disclosed that includes front and back panels each having a first zone and a second zone. The first zone is extensible and retractable and the second zone is non-extensible and non-retractable. The disposable absorbent article also has a waistband integrally formed in the first zone that has extensible regions separated by non-extensible regions. The waistband is constructed such that a greater force is required to extend it than is required to extend the remaining extensible portion of the first zone in both the front and back panels. The disposable absorbent article also includes an absorbent assembly and the front and back panels are secured together by a pair of seams to form a waist opening and a pair of leg openings.
Abstract:
A method for producing a disposal wearing article comprising a step for producing an elastic belt material (12) by sandwiching an elastic member (4) under a stretched state between two sheets of web (10, 11) in the longitudinal direction thereof, a step for dividing the elastic belt material (12) into two in the widthwise direction such that protrusions (12a) and recesses (12b) appear alternately, a step for separating the first and second divided elastic belt materials in the widthwise direction, a step for shifting the phases of the first and second divided elastic belt materials in the longitudinal direction such that the protrusions and recesses become in-phase, a step for reducing the shrinking force of the elastic member in the vicinity of the protrusions (12a) of the first elastic belt material (12A) and the second elastic belt material (12B), and a step for fixing an absorber (2) across a part (12c) of the first elastic belt material (12A) and the second elastic belt material (12B) where the shrinking force is reduced.
Abstract:
The disposable diaper according to the present invention comprising a liquid permeable topsheet, a liquid impermeable backsheet, and a liquid retentive absorbent member interposed between the topsheet and the backsheet, and having a pair of inner sheets (18, 18') which are connected to the backsheet and are provided at opposite longitudinal side portions of the disposable diaper on its topsheet side such that the longitudinal inner side edges of the inner sheets are located inwardly along the longitudinal side edges of the absorbent member; each of the inner sheets comprises a laminate of a non-woven fabric and a film, and is arranged such that the non-woven fabric is located on the skin-contacting surface side of the diaper, and wherein the backsheet comprises a laminate of a non-woven fabric and a film, and is arranged such that the non-woven fabric is located on the outer skin-noncontacting surface side of the laminate.
Abstract:
The present invention relates to a method of manufacturing an absorbent article in the form of a pants-type diaper or a sanitary panty, starting from a flat blank (A-C) which includes an elongated absorbent body (5) enclosed between two casing sheets (2, 9) which at opposing front and rear end parts of the absorbent body have side parts (19, 20 and 21, 22 respectively) which extend laterally beyond the body on both sides thereof, said method comprising the step of folding the blank around a transverse axis so that the end edges (16, 17) of the side parts lie edge-to-edge. According to the invention, at least one folded band (13) of flexible material is placed between each pair of front and rear side parts (19, 21 and 20, 22 respectively) which lie opposite one another in the folded state of the blank, and the free ends of the bands are fastened to adjacent side parts. The invention also relates to an article manufactured in accordance with the method.
Abstract:
A disposable absorbent article is disclosed that includes a first waist region, a second waist region, a crotch region disposed between the first waist region and second waist region, a waist edge in the first waist region, at least one waistband in the first waist region adjacent the waist edge, at least one fastener in the second waist region, and a waist assembly in the first waist region, wherein the waist assembly has a Corrugation Regularity greater than about 75%.
Abstract:
A first elastic material is advanced in a machine direction in a stretched state to a first metering device at a speed, V1. A second elastic material is advanced in the machine direction in a stretched state to a second metering device at a speed, V2. First and second substrate layers are advanced in a machine direction to a third metering at a speed, V3, along with the first and second elastic materials. The first and second elastic materials are bonded to the first and second substrate layers at the third metering device to form a layered elastic substrate. The layered elastic substrate is advanced to a fourth metering device at a speed, V4. V1 is less than V2, V3 is greater than V1 and V2, V4 is less than V3, and V4 is greater than V1 and V2.
Abstract:
An absorbent article having a longitudinal centerline, a front region, a crotch region, and a back region. The absorbent article has a main portion, a side portion, and a waist portion. The waist portion has a belt portion that has a front belt portion having elastomeric material and a back belt portion having elastomeric material. The front belt portion has a first elastic section and a second elastic section, each section having force zones. The back belt portion has a third elastic section and a fourth elastic section, each section having force zones. The force zones in the portions alternate between a high force zone and a low force zone in at least one belt portion.
Abstract:
The disposable pull-on garment has a longitudinal centerline, a front region, a crotch region, and a back region, the front region and the back region being joined at seams to form a waist opening and leg openings. The pull-on garment comprises a main portion, a side portion, and a waist portion. The side portion is disposed transversely outboard of the main portion. The waist portion comprises a center waist portion, an outer side waist portion, and an inner side waist portion. The center waist portion is disposed longitudinally outboard of the main portion. The outer side waist portion is disposed longitudinally outboard of the side portion, transversely outboard of the center waist portion, and contiguous with the seam. The inner side waist portion is disposed longitudinally outboard of the side portion, transversely inboard of the outer side waist portion, and transversely outboard of the center waist portion. The side portion is elasticized to provide elasticity and comprising a side elastic material to contract and gather at least a portion of the side portion. The waist portion is elasticized to provide elasticity and comprising a waist elastic material to contract and gather at least a portion of the waist portion. Contraction rate of the inner side waist portion is less than that of the center waist portion, and contraction rate of the side portion longitudinally inboard of the inner side waist potion is greater than that of the inner side waist portion.
Abstract:
Composite webs having one or more elastic composite structures located on a substrate, methods of manufacturing the composite webs, and articles including the elastic composite structures and substrates are disclosed. The elastic composite structures may preferably include one or more elastic components attached to anchors at two or more locations, wherein the anchors are themselves attached to the substrate. The anchors may preferably be constructed of inelastic polymeric material (and/or exhibit limited to no elasticity in use) and the elastic components may preferably be constructed of elastomeric polymeric material.
