The specific embodiment
As shown in Figure 1, diaper 1 has longitudinal Y and horizontal X, has the both side edges 16 of front and back waist region 11 and low back region 12, the territory, crotch zone 13 between these front and back waist regions 11,12, the front and back ora terminalis 14,15 extending along horizontal X and longitudinally Y extension.In diaper 1, the fastening tab 81 with a plurality of maos of hooks being arranged on low back region 12 is connected separably with the target patch with a plurality of looped piles 82 being arranged on Attacking Midfielder's region 11, thereby can be so that wearer is close in front and back waist region 11,12 and territory, crotch zone 13.
As shown in Figures 2 and 3, diaper 1 has the vertical centrage 2-2 of the binary imagination of the size of horizontal X, and roughly symmetrical with respect to the vertical centrage 2-3 of imagination.
Diaper 1 has interior dough sheet 20 in the liquid permeability of skin forward surface, at its opposition side, be the outer dough sheet 30 of the opaque liquid of non-skin forward surface, the absorption pad 40 of the absorbency inside and outside these between dough sheet 20,30 and the leakage prevention sheet 50 between absorption pad 40 and outer dough sheet 30.On the skin forward surface of interior dough sheet 20, formed a pair of inclosure sheet 60 dividing out at horizontal X.These sheets are bonded with each other by the not shown adhesion means such as hot-melt adhesive.
As outer dough sheet 30, can adopt approximately 10～30g/m of quality
2hydrophobic spunbonded type/melt-blown/spunbonded type (being called SMS below) fabric nonwoven cloth, spunbonded type fabric nonwoven cloth, plastic sheet or these fabric nonwoven cloths and plastic sheet stacked.The non-skin forward surface of dough sheet 30 and on Attacking Midfielder's region 11, is installed with target patch 82 outside.
Bonding leakage prevention sheet 50 on dough sheet 30 outside.Leakage prevention sheet 50 can adopt the plastic sheeting of opaque liquid and breathability.The Area Ratio absorption pad 40 of leakage prevention sheet 50 is large, for preventing from being absorbed urine that pad 40 absorbs etc., escapes to outside diaper 1.On dough sheet 30, fastening tab 81 is arranged on low back region 12 via substrate 83 outside.Substrate 83 is fixed on to be enclosed between sheet 60 and outer dough sheet 30, and, from both side edges 16, towards horizontal X, stretch out, fastening tab 81 is installed in the part of stretching out.
The inner face of dough sheet 30, is fixed wtih leg elastics 51 along both side edges 33 outside.Leg elastics 51 with elongation state collapsible be fixed on and enclose between sheet 60 and outer dough sheet 30.As leg elastics 51, can adopt the elastomer of many wire, strip or wire harness shape.By the contraction of leg elastics 51, the both side edges of diaper 1 has sealing function.
The inner face of leakage prevention sheet 50 bonding absorption pad 40.Absorption pad 40 is at least positioned at territory, crotch zone 13, in the present embodiment, be from territory, crotch zone 13 forwards, backwards waistline region 11,12 stretch out.Absorption pad 40 has the core 41 of absorbency and covers the emulsion sheets such as thin paper 42 of core 41.As core 41, can adopt fluff pulp, superabsorbent polymer particle or their mixture.The size of the horizontal X of core 41 in territory, crotch zone 13 is less than front and back waist region 11,12.Core 41 at least contains mass area ratio and is about 150～250g/m
2fluff pulp, in the present embodiment, also contain mass area ratio and be about 150～250g/m
2superabsorbent polymer particle, compare with disposable diaper before, the quality of core is little.If the quality of core 41 is large, rigidity increases, and the whole flexibility of diaper 1 is poor, and by reducing its quality, can keep the flexibility of absorption pad 40, can be so that diaper 1 integral body has soft sense of touch.
As shown in Figure 4, absorption pad 40 has and is positioned at the absorbing surface 43 of dough sheet 20 sides and is positioned at the i.e. bottom surface 44 of outer dough sheet 30 sides of its opposition side.On absorption pad 40, be provided with the 44 a plurality of recesses 45 towards absorbing surface 43 from bottom surface.Recess 45 is not set on absorbing surface 43, but smooth.Recess 45 can be from bottom surface 44 forms absorption pad 40 pressurized, heated towards absorbing surface 43.By recess 45 is set, in bottom surface 44, can increase the area that core 41 can absorb urine etc.Because the core quality of absorption pad 40 is smaller, absorbtivity to body fluid such as urine likely correspondingly reduces, but, by recess 45 is set, can increase the area of energy absorb body fluids and effectively use this area, so, even the little absorption pad of core quality also can keep enough absorbabilities.
Absorption pad 40, because the mass area ratio of core 41 reduces, so especially in territory, crotch zone 13, core 41 easily move with wearer's leg action etc., core 41 is easily concentrated and become close or its periphery and become sparse partly.But, by recess 45 is set on absorption pad 40, can prevent the movement of core 41.At recess 45, core 41 is pressurized, so, to compare with other region that recess 45 is not set, the density of core 41 increases.Therefore, the part at recess 45 places, rigidity increases, and can produce poor rigidity between other region.In addition, at recess 45 places, its reduced thickness, so X is crooked along recess 45 towards longitudinal Y with laterally for absorption pad 40, can be close to wearer.In addition, in the front and back waist region 11,12 that does not form recess 45, compare with the region that has formed recess 45, rigidity step-down, can realize soft quality.Caregivers such as mothers, hold diaper 1 and wait while putting on to baby, caregiver holds territory, crotch zone 13 but holds front and back waist region 11,12, so, can more feel flexibility, the sense of touch of diaper 1.
All the area occupation ratio of recesses 45 be territory, crotch zone 13 area approximately 2～10%.The size of the horizontal X of recess 45 is about 3mm, and longitudinally the size of Y is about 1mm, along laterally X extension.At the horizontal adjacent recess 45 of X, it is about 15mm at a distance of size.At longitudinal adjacent recess 45 of Y, it is about 15mm at a distance of size.At longitudinal adjacent recess 45 of Y, phase non-overlapping copies, is configured to utilize a plurality of recesses 45 to describe so-called interlaced pattern.Diaper 1 is easily along recess 45 bendings, and by recess 45 is extended along horizontal X, diaper 1 easily bends to especially and makes front and back ora terminalis 14,15 mutually close in crotch 13.Therefore, diaper 1 is easily close to wearer's crotch.In addition, recess 45, along laterally X extension, bends thereby be not easy the imaginary line of Y along the longitudinal.Therefore, in the wearing of diaper 1, even the both side edges 16 of diaper 1 by wearer's huckle towards horizontal X inner side extruding, also can prevent the bending of absorption pad 40.
Again as shown in Figure 3, on the absorbing surface 43 of absorption pad 40, dough sheet 20 in engaging.Interior dough sheet 20 has and is positioned at the surface 25 of skin forward surface and the back side 24 of opposition side thereof, and the absorbing surface 43 that tegillum builds up the back side 24 and absorption pad 40 in opposite directions.As interior dough sheet 20, for example, can adopt quality to be about 15～35g/m
2, be preferably about 25～30g/m
2gas wear fabric nonwoven cloth.
As shown in Fig. 4～6, interior dough sheet 20 has middle section 28 and smooth both sides 29.On the surface 25 of middle section 28, there is a plurality of ridge portions 26 and ditch portion 27.Smooth both sides 29, are positioned at the horizontal X outside of middle section 28, do not form ridge portion 26 and ditch portion 27.Ridge portion 26 and ditch portion 27 longitudinally Y extend, and in horizontal alternate configurations.The pitch of ridge portion 26 and ditch portion 27 is about 2～7mm.
The ridge portion 26 of interior dough sheet 20 and ditch portion 27 can be with following method manufactures.As interior dough sheet 20, can adopt fabric nonwoven cloth, fabric nonwoven cloth is to be formed by the fleece of having assembled staple fibre.Such fleece is positioned in to advance and is with and transports towards operating direction, meanwhile, from arranging at regular intervals so that the nozzle that crosses fleece sprays the fluids such as the injection air that heated, injection water, uperize to fleece along crisscross.By fluid jet fleece in, staple fibre is partly towards crisscross movement, being formed ditch portion 27 by the part of fluid jet, in its formation ridge, both sides portion 26.In addition, fluid is injected into the part corresponding with middle section 28, and is not injected into the part corresponding with two side areas 29.The interior dough sheet 20 of making like this, the height of the density ratio ditch portion 27 of the short fiber of ridge portion 26.
As shown in Figure 5 and Figure 6, on surface 25, form a plurality of compression recesses 70.Compression recess 70 consists of the 1st～4th compression recess 71～74, the 1st compression recess 71 be positioned at the 1st imagination on straight line with the 75 and the 2nd imagination with 76 intersection point place.Delimit respectively the 1st and the 2nd imagination with 75,76 both side edges at a distance of size, be width dimensions, the opening diameter while be circle with the 1st compression recess 71 is roughly the same.The 2nd compression recess 72, at least its center is not with 75 with the 1st and the 2nd imagination, 76 center is consistent, and it is 75,76 overlapping that its part and the 1st and the 2nd imagination are with.Therefore, the 1st compression recess 71 and the 2nd compression recess 72, its center is mutually in a straight line not overlapping.The 3rd compression recess 73 and the 1st and the 2nd compression recess 75,76 are not overlapping; And, from the size at 3 compression recess 73 centers, the 1st compression recess 71 center to the, than little from the size at 2 compression recess 72 centers, the 1st compression recess 71 center to the, specifically, be about 1.8mm.The 4th compression recess 74 center and the 1st and the 2nd imagination is consistent with the either party in 75,76.The the 1st and the 2nd imagination is with 75,76 to intersect with the vertical centrage 2-2 of imagination and with respect to imagining center line 2-2 symmetry.
In the 1st and the 2nd imagination, be with on 75,76, the 1st compression recess 71 is each other at a distance of about 15mm, and the 2nd compression recess 72 between them is each other at a distance of about 1mm.The 2nd compression recess 72 is with 75,76 to arrange symmetrically with respect to the 1st and the 2nd imagination.In the present embodiment, the 4th compression recess 74 between the 1st compression recess 71 is 1, is provided with a pair of the 2nd compression recess 72 between the 1st compression recess 71 and the 4th compression recess 74.If the 1st compression recess 71 and the 2nd compression recess 72 center are with on 75,76 and are arranged in a straight line in the 1st and the 2nd imagination, interior dough sheet 20 will be recessed point-blank along them, and recessed and wearer's skin contact of straight line, will cause stimulation to wearer's skin.But, in the present embodiment, due to the 2nd compression recess 72 center not with the 1st and imagination be with 75,76 consistent, so, between the 1st compression recess 71, there will not be interior dough sheet 20 to be with along the 1st and the 2nd imagination 75,76 recessed point-blank.In other words, because the 1st and the 2nd imagination that partly staggers is with 75,76 to be recessed into agley, so, the skin that is not easy to stimulate wearer.In addition, also can give the impression that seems also soft.In addition, whole interior dough sheet 20 is along the 1st and the 2nd imagination with near 75,76 bending, and these the 1st and the 2nd imaginations are with 75,76 to intersect, so the soft ground of interior dough sheet 20 is crooked and be easily close to wearer's skin.In addition, the 3rd compression recess 73 is provided with a plurality of near the 1st compression recess 71, and like this, visually, the 1st and the 2nd imagination is unobvious with 75,76 intersection point, gives soft impression.The diameter of the 3rd compression recess 73 is preferably little than the diameter of the 2nd, the 4th compression recess 72,74.
The 1st compression recess 71 at a distance of size be adjacent the 1st imagination with 75 at a distance of size and adjacent the 2nd imagination with 76 at a distance of size.By these are done greatlyr at a distance of size, just can make the interior dough sheet 20 that the gauge that reduces interior dough sheet 20 within reason just maintains the sense of touch of bulk softness.
Compression recess 70 is configured to ridge portion 26 and ditch portion 27 all overlapping.When overlapping in any recess and the ridge portion 26 of compression recess 70, towards its thickness direction, compress a part for ridge portion 26, its gauge is reduced than other parts.Similarly, when overlapping in compression recess and ditch portion 27, towards its thickness direction, compress a part for ditch portion 26, its gauge is reduced than other parts.But the decrement of ditch portion 26 is less than the decrement of ridge portion 26.
Due to the tabular surface of interior dough sheet 20 be bottom surface 24 with the tabular surface of absorption pad 40 be absorbing surface 43 in opposite directions, so, the bottom surface 24 of interior dough sheet 20 and absorbing surface 43 roughly whole contact.If form recess on absorbing surface 43, absorbing surface 43 just reduces with the contact area of bottom surface 24, and correspondingly, body fluid is not easy to shift towards absorption pad 40 from interior dough sheet 20.But in the present embodiment, can prevent this point, preventing humor is trapped on interior dough sheet 20 in advance.
Large at a distance of size at a distance of the size recess 45 more adjacent than longitudinal Y of the 1st compression recess 71 that longitudinally Y is adjacent.By recess 45 is set on absorption pad 40, compare when recess not being set, its rigidity increases, and the 1st compression recess 71 by dough sheet 20 in increasing at a distance of size, in having formed the territory, whole crotch zone 13 of recess 45, can prevent its rigidity excessively to increase.
The ridge portion 26 of interior dough sheet 20, compares with ditch portion 27, and the density of staple fibre is high.On interior dough sheet 20, the compression recess 70 that formation and ridge portion 26 and ditch portion 27 are overlapping, in the forming section of compression recess 70, density increases more.Therefore, body fluid is especially easily assembled towards the compression recess 70 of ridge portion 26, and body fluid is transferred to absorption pad 40 near compression recess 70.On absorption pad 40, in its bottom surface 44, there is recess 45, the part at recess 45 places, the increase in density of core 41.Therefore, the body fluid easily recess 45 from the compression recess 70 of interior dough sheet 20 towards absorption pad 40 moves, and preventing humor is trapped on interior dough sheet 20 more in advance.In the present embodiment, as interior dough sheet 20, be to adopt fabric nonwoven cloth monolayer, that be formed with ridge portion 26 and ditch portion 27, still, also can for example the fabric nonwoven cloth that does not form ridge portion 26 and ditch portion 27 be stacked in to its rear side and use.
Again as shown in Figure 3, the middle section 28 of interior dough sheet 20 is overlapping with absorption pad 40, and two side areas 29 is positioned at the horizontal X outside of absorption pad 40.In two side areas 29, install and enclose sheet 60.As enclosing sheet 60, can adopt quality to be about 10～30g/m
2sMS fabric nonwoven cloth.Enclose the front and back ora terminalis 61,62 of sheet 60 and the front and back ora terminalis 21,22 of interior dough sheet 20 consistent and mutually bonding.Because front and back ora terminalis 21,22 is bonded in the smooth two side areas 29 of interior dough sheet 20, so, can it is bonding securely.Enclose the peri position edge 63 of sheet 60, overlapping and be bonded with each other with the both side edges 33 of outer dough sheet 30.Enclose the amphi position edge 64 of sheet 60, at horizontal X, configure dividually, these amphi position edges 64 are overlapping with interior dough sheet 20, but do not engage, can be separated with interior dough sheet 20.In amphi position edge 64, formed not shown cover portion, the elastomer 65 that longitudinally Y extends with elongation state collapsible be arranged in this cover portion.By such installation elastomer 65, amphi position edge 64 is separated with interior dough sheet 20 and erect, and is close to wearer's skin, can prevent that urine from waiting the outside that drains to diaper 1.
According to above-mentioned diaper 1, by forming recess 45 on the bottom surface 44 at absorption pad 40, even the little absorption pad of the mass area ratio of core 41 can not reduce its absorbability yet.In addition, due to the smooth absorbing surface 43 that does not form recess 45 and interior dough sheet 20 in opposite directions, so their area in opposite directions does not reduce, body fluid can promptly be transferred to absorption pad 40 from interior dough sheet 20, can prevent that body fluid is trapped on interior dough sheet 20.
The disclosed content of foregoing invention, at least can be summarized as following all.
The present invention is the improvement to following disposable diaper 1.Disposable diaper 1 has longitudinal Y and horizontal X, comprises the non-skin forward surface, front and back waist region 11,12 of skin forward surface and opposition side thereof, in the territory, crotch zone 13 between these front and back waist regions 11,12, at the interior dough sheet 20 of above-mentioned skin forward surface, at the outer dough sheet 30 of above-mentioned non-skin forward surface with between above-mentioned inside and outside dough sheet 20,30 and be at least positioned at the absorption pad 40 in territory, above-mentioned crotch zone 13.
