Detailed description of the invention
As shown in Figure 1, diaper 1 has substrate 10 and the fastening system that front and back waist region 11,12 can be coupled together.Substrate 10 has longitudinal Y and horizontal X, comprises front and back waist region 11 and rear waist area 12, is positioned at front and back ora terminalis 14,15 that territory, crotch zone 13, transversely X between this front and back waist region 11,12 extend and the longitudinally both side edges 16 that extends of Y.Fastening system has the hair hook element 81 be arranged on rear waist area 12 and the loop elements 82 be arranged on front waist area 11, hair hook element 81 is connected separably with loop elements 82, thus, front and back waist region 11,12 and territory, crotch zone 13 can be made to be close to wearer.
As shown in Figure 2 to 4, diaper 1 has indulges centrage 2-2 by binary for the size of horizontal X imagination, indulges centrage 2-2 roughly symmetrical relative to imagination.
Diaper 1 has at the inner sheet 20 of the liquid permeability of skin forward surface, opaque liquid outer sheet 30, the absorbency absorber 40 in these between outer sheet 20,30 and the leakage prevention sheet 50 between absorber 40 and outer sheet 30 at its opposition side and non-skin forward surface.The skin forward surface of inner sheet 20 is configured with a pair inclosure sheet 60 be separated at horizontal X.At least form substrate 10 by inner sheet 20 and outer sheet 30, and, between interior outer sheet 20,30, by the bonding absorber 40 of known bonding way and leakage prevention sheets 50 such as the heatmeltable bonding agents of scheming not show.
Via hair hook element 81 mounting and adjusting sheet 83 on the loop elements 82 of the non-skin forward surface (outside) of the outer sheet 30 in front waist area 11.
Fibre plate can be adopted, such as quality about 10 ~ 30g/m as outer sheet 30
2water proofing property spunbonded type/melt-blown/spunbonded type (hereinafter referred to SMS) fabric nonwoven cloth, spun bond fibrous non-woven fabrics or melt-blown fabric nonwoven cloth.Fabric nonwoven cloth such as can be melt and dissolved the thermoplastic synthetic resin be made up of polyethylene, polypropylene, nylon, polyester etc., extrudes continuous print long fibre shape, and direct aggregation and being formed.Therefore, such fabric nonwoven cloth is made up of long filament (continuous fiber).Outer sheet 30 has the front and back ora terminalis 31,32 of transversely X extension and the both side edges 33 of longitudinally Y extension.The both side edges 33 of outer sheet 30, in territory, crotch zone 13, in horizontal X, side is recessed, and the size of separation of both side edges 33 reduces.
As shown in Figure 4 and Figure 5, outer sheet 30 has middle section 34 and is positioned at the two side areas 35 outside the horizontal X of middle section 34.Middle section 34 and two side areas 35 between front and back ora terminalis 31,32 all along the longitudinal Y extend continuously continuously.Multiple recess 37 is defined at middle section 34.As shown in Figure 6, recess 37 transversely X extends, and intermittently arranges along imaginary line 36, and this imaginary line 36 longitudinally Y configures many.In the middle section 34 with recess 37, a face of sheet 30 is about 700 ~ 900 μm to the size of the thickness direction in another face from the outside.The high accuracy shape measuring system that this size can be produced with Keyemce company of Co., Ltd. and high speed, high accuracy CCD laser displacement gauge mensuration.Namely, in middle section 34, measuring the most concave point from defining recess 37 part, to the size not forming recess 37 part be adjacent, the size namely measuring the point from above-mentioned point to maximum gauge direction, it can be used as the size of the thickness direction of outer sheet 30.In addition, the size of the thickness direction in two side areas 35 is about 300 ~ 350 μm.By forming recess 37, compared with the situation not forming recess, the size of the thickness direction of outer sheet 30 can be strengthened.Like this, by strengthening the size of thickness direction, the flexibility of the outer sheet 30 in the method can be improved.In this embodiment, the area occupation ratio of the recess 37 in middle section 34 is about 20 ~ 60%, is at least about 2 ~ 10%.
Because the middle section 34 of dough sheet 30 outside arranges recess 37, so in middle section 34, a part for fiber is extended and bending, the feel of the softness similar to the fibrous underwear such as cotton can be obtained.In addition, due to fiber bending, the rigidity of outer sheet 30 can be made to reduce, and feel is better.In addition, owing to intermittently configuring recess 37 at horizontal X and longitudinal Y, so, when any horizontal X of dough sheet 30 and longitudinal Y makes hands slide in the mode of stroking outside, not level and smooth sense of touch, but soft sensation.
Above-mentioned outer sheet 30 is provided with recess 37, thus, at least flexibly stretches on longitudinal Y, so when wearing diaper 1, diaper 1 may be sagging.But, in the both sides of middle section 34 being formed with recess 37, owing to being provided with the two side areas 35 not forming recess 37, so, compared with the situation of this two side areas 35 is not set, can suppresses to extend, can diaper sags be prevented.As outer sheet 30 owing to adopting the fabric nonwoven cloth formed by long filament (continuous fiber), so, compared with the fabric nonwoven cloth formed by staple (short fiber) with employing, the extension because fiber reinforced cement composite causes can be prevented, make outer sheet 30 more be not easy to stretch.In addition, as outer sheet 30 by adopting long filament, can prevent because of formed recess 37 cause the disrumpent feelings of outer sheet 30, perforate on dough sheet 30 outside can be prevented.
Again as shown in Figures 2 to 4, the inner surface of dough sheet 30 outside, bonding leakage prevention sheet 50.Opaque liquid can be adopted and the plastic sheeting of poisture-penetrability as leakage prevention sheet 50.The area ratio absorber 40 of leakage prevention sheet 50 is large, can prevent the urine etc. by absorber 40 absorbs from draining to outside diaper 1.In addition, the size of the horizontal X of leakage prevention sheet 50 is larger than absorber 40, and less than outer sheet 30.Middle section 34 and the leakage prevention sheet 50 of outer sheet 30 configure overlappingly.The plastic sheeting used due to leakage prevention sheet 50 is not easy to extend, in addition, due to bonding absorber 40, so the middle section 34 of outer sheet 30 is not easy to extend more, and diaper 1 can be prevented in use sagging.
Dough sheet 30 outside, hair hook element 81 is arranged on rear waist area 12 via tab 83.Adjustment blade 83 is fixed on encloses between sheet 60 and the two side areas of outer sheet 30, and extends from both side edges 16 to horizontal X, installs hairiness hook element 81 in the part of extending.Tab 83 is fixed in the two side areas 35 that to be not easy to extend compared with middle section 34, therefore, when being engaged with loop elements 82 by hair hook element 81, the standing part of tab 83 and outer sheet 30 extends, and the waist opening of diaper 1 can be prevented to unclamp from the waist of wearer.
The inner face of dough sheet 30 outside, is fixed with leg elastics 51 along both side edges 33.Leg elastics 51 with the state of having extended collapsible be fixed on and enclose between sheet 60 and outer sheet 30.The elastomer of many cord shapes or wire harness shape can be adopted as leg elastics 51.By the contraction of leg elastics 51, the both side edges of diaper 1 has sealing function.
Leg elastics 51 is configured in the two side areas 35 of outer sheet 30 overlappingly.Owing to being installed on the two side areas 35 being not easy to stretch compared with middle section 34 overlappingly, so the both side edges of diaper 1 is easily close to the huckle of wearer.
Absorber 40 is engaged between leakage prevention sheet 50 and inner sheet 20.Absorber 40 is at least positioned at territory, crotch zone 13, and in present embodiment, from territory, crotch zone 13, rear waist area 11,12 is extended forward.Absorber 40 has the emulsion sheet 42 (see Fig. 5) of the thin paper of absorbent core 41 and covering core 41 etc.Fluff pulp, superabsorbent polymer particle or their mixture can be adopted as core 41.Little than front and back waist region 11,12 of the size of the horizontal X in the territory, crotch zone 13 of core 41.
The absorbing surface of absorber 40 engages the inner sheet 20 of liquid permeability.As inner sheet 20, such as, can adopt quality about 15 ~ 35g/m
2, best about 20 ~ 30g/m
2point glue fiber type non-woven fabrics etc.
Inner sheet 20 is installed with a pair inclosure sheet 60 be separated at horizontal X.Quality about 10 ~ 30g/m can be adopted as inclosure sheet 60
2sMS fabric nonwoven cloth etc.Enclose the front and back ora terminalis 21 of front and back ora terminalis 61,62 and the inner sheet 20 of sheet 60,22 consistent and they are mutually bonding.The peri position edge 63 enclosing sheet 60 overlaps in the both side edges 33 of outer sheet 30, and is bonded with each other in two side areas 35.The amphi position edge 64 enclosing sheet 60 configures discretely at horizontal X, and these amphi position edges 64, although overlap in inner sheet 20, do not engage with inner sheet 20, can be separated from inner sheet 20.Define the cover (ス リ ー Block that figure does not show in amphi position edge 64) portion, longitudinally Y extend elastomer 65 with extend state collapsible be arranged in this cover portion.By installing elastomer 65 in this wise, amphi position edge 64 erects from inner sheet 20 and leaves inner sheet 20, is close to the skin of wearer, can prevent urine etc. from draining to the outside of diaper 1.In addition, peri position edge 63, outside in dough sheet 30, is bonded in the two side areas 35 that to be not easy to extend compared with middle section 34, so amphi position edge 64 is not easy the huckle leaving wearer, easily maintains the state of contiguity.
Recess 37 in above-mentioned outer sheet 30 can be formed by following methods.As shown in Figure 7 and Figure 8, on the fleece 3 forming outer sheet 30, recess 37 is formed by a pair the 1st rollers 91 and the 2nd roller 92.The side face 94 of the 1st roller 91 is provided with multiple lobe (pin) 93.Lobe 93 intermittently arranges in line along the direction of principal axis of the 1st roller 91.In lobe 93, the size S1 from the side face 94 of the 1st roller 91 to top 95 is about 1.0mm, is about 2.0mm in the interval S 2 of the adjacent lobe 93 of direction of principal axis.Like this in arrangement lobe 93 in line, multiple in the circumferential direction arrangement of the 1st roller 91, in the circumferential direction the separately size S3 of adjacent lobe 93 be about 2.6mm.The top 95 of lobe 93 is the rectangles axially extended, and axial size is about 1.0mm, and the size of circumferential direction is about 0.5mm.
The side face 96 of the 2nd roller 92 defines in the circumferential direction multiple raised lines 97 of intermittently arranging, between these raised lines 97, define the recessed bar 98 engaged with lobe 93.Raised line 97 and recessed article 98 extend continuously at the direction of principal axis of the 2nd roller 92, and in the circumferential direction alternately configure.The size S4 of the thickness direction of recessed bar 98 is about 1.0mm.The fleece 3 forming outer sheet 30 is transported between the 1st and the 2nd roller 91,92, thus, fleece 3 defines the recess 37 corresponding with lobe 93.
1st roller 91 is heated to the low temperature of the melting point of the thermoplastic resin used than outer sheet 30.In the present embodiment, about 80 ~ 110 DEG C are heated to.Therefore, the fiber of outer sheet 30 can not heat fusing, and fiber is easily extended.Therefore, in the part for part being formed with recess 37, fiber is extended, bending, can improve feel.In addition, in the part be extended, fiber attenuates, and can obtain more soft feel.
On the 1st roller 91, lobe 93 intermittently arranges at direction of principal axis.On the 2nd roller 92, recessed bar 98 in direction of principal axis arrangement, thus, outside on dough sheet 30, defines the bar ditch along imaginary line 36 in the part corresponding with the separate section of lobe 93 continuously.This is because between the lobe 93 of the 1st roller 91, outer sheet 30, by these lobe 93 stretch-draw, defines the bar ditch of wire.Like this, owing to defining bar ditch, outer sheet 30 easily bends along bar ditch, can realize more soft feel.
Outside on dough sheet 30, bar ditch is transversely X extension only, and longitudinally Y does not extend.If all form bar ditch at longitudinal Y and horizontal X, then outer sheet 30 is all easily extended at longitudinal Y and horizontal X, and when manufacturing diaper 1 when transport outer sheet 30, shape can be unstable.Therefore, only bar ditch is formed in vertical or horizontal either party.In addition, if during the longitudinally Y extension of bar ditch, outer sheet 30 is transversely X elongation easily, and when horizontal X stretch-draw hair hook element 81, concomitantly extend at horizontal X therewith, like this, wearing in diaper 1, the adhesion of waist opening may reduce.But in the present embodiment, bar ditch is that transversely X extends, and can prevent the problems referred to above thus.
In the present embodiment, the two side areas 35 of dough sheet 30 does not form recess 37 outside, thus, can prevent outer sheet 30 overall elongated, but, by arranging pressure contact portion in two side areas 35, the casual elongation of outer sheet 30 more can be prevented.Outer sheet 30 by heating, pressurized treatments, partly can crimp and is formed by pressure contact portion.Pressure contact portion can only be located in outer sheet 30, also outer sheet 30 and other sheet material stacked with it heating, pressurization can be arranged.
