A disposable diaper product useful for collecting a urine sample from an infant is disclosed. In one example the product may have a liquid control structure overlying a liquid impermeable backsheet, with a plan surface area defining a volume coextensive therewith, wherein a portion of the volume defined by at least 50 percent of the plan surface area contains no more than 50 percent by weight absorbent material. In another example the product may have a liquid control structure overlying a liquid impermeable backsheet, and have an average Liquid Release Ratio of at least 3 percent. A method for collecting a urine sample from an infant is also disclosed, in which a diaper is used for collection.

The present disclosure relates to an array of disposable absorbent articles adapted for different activities, the array comprising a first package comprising a plurality of pant-type absorbent articles (10), configured to be worn about the lower torso of a wearer and a second package comprising a plurality of pad-type absorbent articles (10′), configured to be fastened to an undergarment, wherein the absorbent core (1,1′) of said pant-type and said pad-type absorbent articles (10,10′) comprises absorbent material selected from the group consisting of cellulose fibers, superabsorbent polymers and combinations thereof, said absorbent material being contained within at least one core wrap substrate enclosing said absorbent material, and wherein a top layer of said core wrap is adhered to a bottom layer of said core wrap to form one or more channels (4) substantially free of said absorbent material.

An absorbent core structure comprising: a first piece of absorbent core material, a second piece of absorbent core material, an upper wicking layer, a lower wicking layer, and a barrier layer. The upper wicking material is located above the first and second piece of absorbent core material. The lower wicking layer is located below the first and second piece of absorbent core material. The absorbent core structure further includes a channel between the first and second piece of absorbent core material. The upper wicking layer is bonded to the lower wicking layer at a bottom portion of the channel and the barrier layer is bonded to the lower wicking layer.

An absorbent article includes a first waist region, a second waist region, and a crotch region disposed between the first and second waist regions; and a chassis comprising a topsheet, a backsheet and an absorbent core. The article also includes a waist feature joined to the chassis a waist region and having a portion extending longitudinally outboard of the chassis in said waist region. The backsheet has a barrier layer having a maximum length, L.sub.BS. The absorbent core has absorbent material and a maximum length, L.sub.CW, and wherein L.sub.CW is substantially the same as L.sub.BS. The absorbent material is disposed in an absorbent material deposition area. The absorbent material deposition area has a maximum length, L.sub.AB, wherein L.sub.AB is about 90% or greater of L.sub.BS. The first absorbent area lateral edge is disposed a longitudinal distance, D1, from the first barrier lateral edge, wherein D1 is 5% or less of L.sub.BS.

A urine absorption pad for preventing leakage of urine is provided. A urine absorption pad includes: a front surface sheet (16) which has water permeability and contacts a skin; a back surface sheet (17) which has water impermeability and contacts underwear; an absorbent (18) which is sandwiched between the front surface sheet (16) and the back surface sheet (17) and absorbs urine having passed through the front surface sheet (16); and a guide A (11) and a guide B (12) which allow urine to permeate and are self-standing so as to rise to the front surface sheet (16) side with respect to the absorbent (18) to control flow of urine. The guide A (11) is arranged at an edge portion, and the guide B (12) is arranged so as to extend in a left-right direction.

An absorbent hygienic article for absorbing body fluids, the article including a liquid absorbent top layer and a backing layer, the top layer and the backing layer being made from roll materials and being joined together. The top layer is constituted by a cellulosic fibrous web, the fibres in the cellulosic fibrous web being constituted by a mixture of cellulose fibres, the mixture including regenerated cellulose fibres or natural cellulose staple fibres and cellulose pulp fibres, the cellulosic fibrous web being a foam-formed, hydroentangled cellulosic fibrous web.

Absorbent articles including sanitary napkins, panty liners and incontinence pads, wherein an end portion in the longitudinal direction of the absorbent article is reduced from rising by the contraction force of an elastic stretchable member, and the absorption performance is improved and lateral leakage is prevented. In FIG. 5, a sanitary napkin 1 includes a side nonwoven fabric 7 that has an absorber 4 interposed between a permeable front sheet 3 and an impermeable back sheet 2 and forms a solid gather BS rising on each of both side portions on a skin side by a contraction force due to an elastic stretchable member 14. The side nonwoven fabric 7 has a fixed zone 20 joined to the absorbent article 4 side by folding back in both end portions in the longitudinal direction of the napkin, a standing zone 21 rising on a skin side by joining the elastic stretchable member 14 in an intermediate portion in the longitudinal direction of the napkin, and a non-fixed zone 22 where the elastic stretchable member 14 is neither joined between the fixed zone 20 and standing zone 21 nor joined to the absorber 4 side.

An absorbent article includes a liquid permeable, apertured topsheet, a liquid impermeable backsheet, an absorbent core disposed at least partially intermediate the topsheet and the backsheet, and an acquisition material disposed at least partially intermediate the topsheet and the absorbent core. The acquisition material has a caliper in the range of about 2.5 mm to about 10 mm, according to the Caliper Test, and an Air Permeability in the range of about 5,000 l/m.sup.2/s to about 11,000 l/m.sup.2/s, according to the Air Permeability Test. The acquisition material has a first surface, a second surface, and a plurality of three-dimensional features extending outwardly from the first surface or the second surface.

A disposable diaper product useful for collecting a urine sample from an infant is disclosed. In one example the product may have a liquid control structure overlying a liquid impermeable backsheet, with a plan surface area defining a volume coextensive therewith, wherein a portion of the volume defined by at least 50 percent of the plan surface area contains no more than 50 percent by weight absorbent material. In another example the product may have a liquid control structure overlying a liquid impermeable backsheet, and have an average Liquid Release Ratio of at least 3 percent. A method for collecting a urine sample from an infant is also disclosed, in which a diaper is used for collection.

Absorbent articles having three-dimensional, apertured, liquid permeable topsheets, acquisition materials, liquid permeable backsheets, and absorbent cores are disclosed. The absorbent articles provide improved topsheet dryness, reduced collagen rewet, and improved modified fluid acquisition.
