The specific embodiment
The disposable baby fluids absorbent garment having disposal securing means that following conduct the present invention relates to is specifically described as an example of disposable diaper example.
Fig. 1 is the biopsy cavity marker devices top view of disposable diaper 1.Diaper 1 has the top flat 2 of liquid permeability, the egative film 3 of opaque liquid and the body liquid absorptive core 4 between these two 2,3, and a part for top flat 2 is covered by the emulsion sheet 5 of the liquid permeability of installing via hot-melt adhesive 43.Top flat 2 and egative film 3 are extending and overlapping part engages via hot-melt adhesive (not shown) from the periphery of core 4.In addition, diaper 1 has orthogonal fore-and-aft direction A, width B and thickness direction C (with reference to figure 2), form territory, crotch zone 6 at fore-and-aft direction A, be positioned at territory, crotch zone 6 front Attacking Midfielder's region 7 and be positioned at the low back region 8 at the rear in territory, crotch zone 6.It is bending that the inner side of the edge, both sides 11 towards horizontal B in territory, crotch zone 6 forms convex ground, between top flat 2 and egative film 3 on this edge, both sides 11, lower limb encloses elastomeric element 12 and extends with elongation state, is bonded on these two 2,3 at least one party via hot-melt adhesive (not shown).Restraint zone 14 for connecting front and back waist region 7,8 has been installed on the edge, both sides 13 of low back region 8.Between the top flat 2 and egative film 3 of the end edge portion 17,18 in front and back waist region 7,8, waistline elastomeric element 7a, 8a extend to horizontal B with elongation state, are bonded on these two 2,3 at least one party via hot-melt adhesive (not shown).Emulsion sheet 5 is arranged on top flat 2 in the mode of the relative fore-and-aft direction centrage P-P symmetry that the width of diaper 1 is divided equally, between end edge portion 17 and end edge portion 18, extends.
Fig. 2 is the profile along the II-II line of Fig. 1, and II-II line is consistent with the cross central line Q-Q that the size of the fore-and-aft direction A of diaper 1 is divided equally.In Fig. 2, top flat 2 has the non-opposite face 2a of the opposite face 2b relative with core 4 and its opposing face, and non-opposite face 2a forms tabular surface.Core 4 is that the aggregation by encase absorbency materials 21 such as pulverizing slurry and super absorbent polymer particles with liquid permeability sheets 22 such as thin papers forms.Emulsion sheet 5 have the surface 31 of skin (not shown) contact of thickness direction C and diaper wearer and with the non-opposite face 2a of top flat 2 the relative back side 32, there is middle section 41 and two side areas 42 at width B.Surface 31 has towards the skin formation convex peak portion 34 that also direction A extends forwards, backwards and forms concavity and the paddy portion 36 of direction A extension forwards, backwards, many (with reference to the figure 3,4) of the each formation of mode alternately to occur at horizontal B of these peak portions 34 and paddy portion 36.In 32, the back side 32 of middle section 44 engages with the non-opposite face 2a of top flat 2 by hot-melt adhesive 43 overleaf, and the back side 32 and the non-opposite face 2a of each two side areas 42 are non-engagement states, can separate with non-opposite face 2a.Hot-melt adhesive 43 is intermittently coated on emulsion sheet 5 and top flat 2 in the mode of the liquid permeability that in fact do not hinder emulsion sheet 5 and top flat 2.In illustrated example, two side areas 42 is respectively in the inner side of the lateral margin 4a of core 4.
Fig. 3, the 4th, in the time wearing diaper 1, an example of top flat 2 and emulsion sheet 5 activities, is the figure identical with Fig. 2.In Fig. 3, once diaper 1 is subject to that body is for example pressed, the side edge part 11 that makes territory, crotch zone 6 is towards the below bending of thickness direction C together with core 4, and in Fig. 2, the top flat 2 of basic horizontal is bending similarly.But, the state that the territory, lateral areas 42 of emulsion sheet 5 can maintenance level or approach level state separate with this non-opposite face 2a.In addition, as shown in Figure 4, in the time applying horizontal power F to territory, lateral areas 42, territory, lateral areas 42 can be out of shape and separate with non-opposite face 2a in curling or bending mode.In order easily to keep such level or to carry out curlingly, territory, lateral areas 42 at least comprises each one of peak portion 34 and paddy portion 36.Peak portion 34 is the part that rigidity is high in territory, lateral areas 42, can bring into play the effect that makes territory, lateral areas 42 remain on level.Paddy portion 36 is the part that rigidity is low in territory, lateral areas 42, makes territory, lateral areas 42 easily curling or bending at horizontal B.In the territory, crotch zone 6 of diaper 1, as shown in Figure 3,4, the territory, lateral areas 42 separating with non-opposite face 2a is positioned at than the position of the more close skin of non-opposite face 2a, can prevent non-opposite face 2a and the contact skin of moisture state.
Fig. 5, the 6th, the figure of the partial perspective view of the thin slice 51 using as emulsion sheet 5 and expression partial sheet 51 end faces.Thin slice 51 is 20～100g/m by containing the hydrophilic fibre (not shown) and the weight per unit area that are made up of the semisynthetic fibre such as natural fiber or rayon fiber of thermoplastic synthetic fiber's 52,40～0 % by weight of 60～100 % by weight
2non-woven fabrics form, in illustrated example, used the thermoplastic synthetic fiber's 52 of 100 % by weight non-woven fabrics.In addition, thin slice 51 has the second direction M consistent using first direction L consistent with the fore-and-aft direction A of diaper 1 when this thin slice, with horizontal B and the consistent third direction N with thickness direction C.The 51a above of thin slice 51 is the parts that become the surface 31 of emulsion sheet 5, below 51b be the part that becomes the back side 32 of emulsion sheet 5,51a forms peak portion 34 and the paddy portion 36 in Fig. 2 in the above, below 51b be formed as smooth.The height of many peak portions 34 is basic identical, and thin slice 51 has thickness j at the top of peak portion 34.Many paddy portions 36 degree of depth from the top of peak portion 34 is basic identical, and thin slice 51 has thickness k in the bottom of paddy portion 36.On thin slice 51, preferred thickness k is no more than 1/3 of thickness j, and thickness j, in the scope of 1.5～5mm, with respect to the length 10mm on the second direction M of thin slice 51, forms 2 to 5 peak portions 34.Thin slice 51 comprises the part 41a that becomes middle section 41 in Fig. 2 and becomes the part 42a of two side areas 42.In order to make thin slice 51 liquid permeabilities good, the thermoplastic synthetic fiber 52 of at least part of 41a in part 41a and part 42a has passed through hydrophilic treated.On part 42a in thin slice 51, although can be to make thermoplastic synthetic fiber 52 through hydrophilic treated, but when part 42a uses as territory, lateral areas 42, in order to prevent just being got wet by body fluid simply, thermoplastic synthetic fiber 52 does not preferably carry out hydrophilic treated but uses or carry out using after water-proofing treatment as hydrophobic fiber.
In addition, in order to make thin slice 51 easily distortion as illustrated in fig. 4, can make density in paddy portion 36 lower than the density in peak portion 34, or make density in paddy portion 36 identical with density in peak portion 34 but make the value of the thickness k of paddy portion 36 be less than the value of the thickness j in peak portion 34.Thin slice 51 in illustrative example is made into, and the density of paddy portion 36, lower than the density of peak portion 34, therefore, alternately occurs in the low-density part of second direction M and highdensity part.On thin slice 51, the density of the density to peak portion 34 and paddy portion 36 compares as follows.That is, the thin slice of Fig. 4 51 is placed on horizontal plane, takes the amplification picture in cross section, obtain in peak portion 34 by the vertical line R at the top of thickness j by this picture

2/ k) as the density of paddy portion 36.
In the time of the diaper 1 of the such Fig. 1 forming of dress, peak portion 34 and contact skin in emulsion sheet 5, and paddy portion 36 separates with skin, the situation that therefore directly contacts skin with top flat 2 is compared, reduce with the contact area of skin, can reduce the moist feeling that diaper 1 produces in the time of moisture state.In addition, if the end edge portion 17 in 5 the past of the emulsion sheet of illustrative example waistline region 7 extends to the end edge portion 18 of low back region 8, the gap forming between peak portion 36 and skin becomes gas-permeable channels, diaper 1 forms the state to atmosphere opening in front and back, therefore the inside and outside breathability of diaper 1 becomes good.In addition, also can implement the present invention so that emulsion sheet 5 does not arrive one or both mode of end edge portion 17,18.The middle section 41 of the body fluid of draining towards emulsion sheet 5 from emulsion sheet 5 absorbed by core 4 through top flat 2.Part body fluid likely spreads to horizontal B on emulsion sheet 5, or spreads to horizontal B on top flat 2.But on the emulsion sheet 5 of the density in the peak of emulsion sheet 5 portion 34 higher than the density in paddy portion 36, the body fluid that paddy portion 36 can suppress on emulsion sheet 5 spreads to horizontal B, prevent at the edge, both sides in territory, the crotch zone 6 11 body fluid skin of making dirty.And, during wearing diaper 1, once body is pressed and is applied on core 4, the body fluid having been absorbed by core 4 likely flows backwards and the skin of getting wet towards emulsion sheet 5 from core 4, but the two side areas 42 of emulsion sheet 5 is owing to not engaging with top flat 2, but trend towards as shown in Figure 3,4 separating with top flat 2, therefore, even flow backwards from core 4 to top flat 2, the body fluid coming moves to emulsion sheet 5 than being easier at middle section 41, but is also difficult to move to emulsion sheet 5 in two side areas 42.Therefore, two side areas 42 reduces because of the situation that the body fluid flowing backwards becomes moisture state, at two side areas 42 skin of can not getting wet.Especially in two side areas 42, when thermoplastic synthetic fiber 52 is the state of hydrophobicity or water proofing property, two side areas 42 can be because body fluid becomes moisture state, and the effect of the skin of not getting wet further improves.In addition, two side areas 42 is the softs that can cover the hot-melt adhesive 43 that engages emulsion sheet 5 and top flat 2, prevents that bonding agent 43 produces stimulation with contact skin during wearing diaper 1.In addition, the emulsion sheet 5 of illustrative example due to the inner side of the edge, both sides 11 in territory, crotch zone 6 forwards, backwards direction A extend, even therefore in the time having worn diaper 1 body fluid flow along paddy portion 36, this body fluid is also difficult to flow towards the outside of diaper 1.
It is below an example of the manufacture method of the thin slice 51 that uses as the emulsion sheet 5 of diaper 1.First one side makes the web (カ mono-De ウ エ Block) of the same thickness being formed by thermoplastic synthetic fiber 52 move to machine direction, and multiple nozzles that one side configures by desired spacing from the direction intersecting with machine direction are to one side injection heated air or the column current of web.Web is placed on the conveyer belt of breathability or water penetration, moves together with this conveyer belt to machine direction.Make in advance the spacing of nozzle consistent with the spacing of the paddy portion 36 on thin slice 51.On this web, thermoplastic synthetic fiber 52 under nozzle, to crisscross movement, thereby form low-density paddy portion 36, between adjacent nozzle and nozzle, form highdensity peak portion 34.Thermoplastic synthetic fiber 52 uses the composite fibre of the fiber such as polyethylene or nylon, polyester or polyethylene and nylon or polyester etc.The top flat 2 of diaper 1 can use the non-woven fabrics or the apertured plastic films etc. that are formed by thermoplastic synthetic fiber.Egative film 3 can use the laminate of plastic sheeting or plastic sheeting and non-woven fabrics etc.Core 4 can be used alone or as a mixture absorbency materials such as pulverizing slurry and super absorbent polymer particles.This absorbency material is preferably by the liquid permeabilities such as thin paper and the good sheet covers of diffusibility.
Fig. 7 is an example that represents embodiment, is the figure identical with Fig. 2.On the diaper 1 of Fig. 7, the territory, lateral areas 42 of emulsion sheet 5 is expanded to horizontal B to arrive the mode of lateral margin 4a of core 4 or the mode that exceedes lateral margin 4a.Such diaper 1, except having the action effect identical with the diaper 1 of Fig. 2, also has following action effect.; even if the body fluid being absorbed by core 4 flows back to top flat 2; or the body fluid of draining at the middle section 41 of emulsion sheet 5 is diffused into the lateral margin 4a of core 4 after being absorbed by top flat 2 or core 4 to horizontal B; because the territory, lateral areas 42 of lateral margin 4a coating cover plate 5 covers, lateral margin 4a and near the body fluid that the contains skin of can not getting wet.The territory, lateral areas 42 of effect also will be according to the size of diaper 1 although it is so, but on horizontal centrage Q-Q, preferably has the size of 10～50mm.
Fig. 8, the 9th, represents to be an example of embodiments of the present invention figures identical with Fig. 1, and to be the profile of the IX-IX line of presentation graphs 8.On the diaper 1 of Fig. 8, form leakproof dike 80 in the edge, both sides 11 in territory, crotch zone 6.Leakproof dike 80 by plastic sheeting or non-woven fabrics etc. in fact the thin slice of opaque liquid form, edge, outside 82, leading section 83 and rearward end 84 engage with respect to the top flat overlapping with them 2 or emulsion sheet 5 by hot-melt adhesive 85.Extending on the edge, inner side 81 of leakproof dike 80, shrink installed with elongation state forwards, backwards direction A extend elastomeric element 86.On leakproof dike 80, the thin slice that refers to that this thin slice is actually opaque liquid has as the necessary minimal opaque liquid of leakproof dike 80 or better opaque liquid.
Although such leakproof dike 80 is the state of lodging on emulsion sheet 5 in Fig. 8,9, if carry out bending but put on diaper 1 at fore-and-aft direction A, elastomeric element 86 shrinks, as shown in dummy line in Fig. 9, the skin (not shown) of edge 81, inner side from emulsion sheet 5 towards wearer erects, can stop body fluid to flow to horizontal B, prevent the side leakage at territory, crotch zone 6 body fluid.In addition, the territory, lateral areas 42 on emulsion sheet 5 is positioned at the position of its downside with respect to the edge, inner side 81 of the leakproof dike 80 of lodging state, also can be at its downside and top flat 2 movable (with reference to figure 9) discretely with respect to the edge, inner side 81 that erects state.Therefore, the edge, inner side 81 of leakproof dike 80 can not interfere with each other and erect with the territory, lateral areas 42 of emulsion sheet 5.This emulsion sheet 5 not only laterally the size of B be less than the size of the horizontal B of top flat 2, and be less than the size between the edge, outside 82 of a pair of leakproof dike 80, while therefore the thin slice that forms leakproof dike 80 being arranged on diaper 1, emulsion sheet 5 can not be in the way.In addition, on this diaper 1, near the end, front and back 83,84 of leakproof dike 80, the end, front and back 45,46 inside can engaging by hot-melt adhesive 87 on the territory, lateral areas 42 of edge 81 and the emulsion sheet 5 overlapping.When leakproof dike 80 in this state erects in edge, inner side 81, the effect that performance makes at least a portion in the territory, lateral areas 42 of emulsion sheet 5 separate from top flat 2.
Illustrated diaper 1 is opening diaper above, but also can implement the present invention with shorts type diaper.As an example of diaper 1 example, the present invention of explanation also can implement with disposable humoral absorbent articles such as sanitary towels in addition.
