In the following description, so-called " non-skin abutment face side " refers to side (face) in the just back of the body both sides (face) of each parts such as absorber 20, that be configured in the opposition side of the skin side of wearer when dressing.So-called " skin abutment face side " refers to side (face) in the just back of the body both sides (face) of each parts, that be configured in the skin side of wearer when dressing.In addition, about the length direction of diaper 10, A side, veutro portion is called " front side ", drosal part B side is called " rear side ".
Diaper 10 comprises: positive dough sheet 21, and it is configured in the skin abutment face side of wearer; Back sheet 23, it is configured in non-skin abutment face side; With the absorber 20 of lengthwise, it is configured between these two sheets 21,23.Positive dough sheet 21 comprises the sheet of liquid permeability, relative with the skin of wearer under the wearing state of diaper 10.Back sheet comprises liquid impermeability or water-repellancy sheet, towards foreign side under wearing state.Particularly there is at the middle section of positive dough sheet 21 hydrophilic region comprising hydrophilic sheet, this is preferred from the permeability of liquid.What is called comprises the hydrophilic region of hydrophilic sheet, comprises the following two kinds situation: the raw material of sheet itself becomes hydrophilic region because comprising hydrophilic fibre; Though comprise hydrophobic fibre with the raw material of sheet itself but produce hydrophilic region by implementing hydrophilicity-imparting treatment.
Diaper 10 is symmetrically formed about the length direction centre line C L extended along its length.Diaper 10 comprises crotch C and the veutro portion A stretched out respectively to length direction front and rear from crotch C and drosal part B of the middle section being positioned at length direction.Veutro portion A is configured in the veutro of wearer when the wearing of diaper 10.Drosal part B is configured in the dorsal part of wearer when the wearing of diaper 10.Crotch C is configured in the lower crotch of wearer when the wearing of diaper 10.Veutro portion A, crotch C and drosal part B are equivalent to the region that diaper 10 trisection of the deployed condition shown in Fig. 1 obtains by Y along its length.
In diaper 10, the left and right sides edge of veutro portion A and the left and right sides edge of drosal part B more stretch out to width foreign side than the left and right sides edge of crotch C respectively.Left and right sides edge side in width of crotch C bends to arc-shaped, has the shape of the inside side's shrinking of middle section of length direction on the whole.Positive dough sheet 21 and back sheet 23 stretch out outward from the left and right sides edge of absorber 20 and rear and front end edge respectively.Positive dough sheet 21 and back sheet 23 directly engage at the extension stretched out outward from the periphery of absorber 20 respectively or are bonded with each other across other parts, to clamp, fix absorber 20.
Diaper 10 is provided with a pair pull stap F, F in the edge, the left and right sides of drosal part B.In the non-skin abutment face of the outer surface (non-skin abutment face) of veutro portion A, i.e. back sheet 23, be provided with and take band (landing tape) L as shown in Figure 2 for fixed agraffe band F, F.
Three-dimensional gauffer formation sheet 162 is configured with respectively in the both sides along its length of diaper 10.Three-dimensional gauffer formation sheet 162 is for the formation of three-dimensional gauffer.Three-dimensional gauffer formation sheet 162 engages with the sheet such as positive dough sheet 21 being positioned at skin abutment face side, and the stiff end that the length direction along diaper 10 is extended and free end form three-dimensional gauffer.And then this rear ends region, in the rear ends region of its length direction, engages with the sheet (such as positive dough sheet 21) being positioned at skin abutment face side and is formed with junction surface, pair of end portions region, front and back 162A, 162B by three-dimensional gauffer formation sheet 162.End regions junction surface 162A is positioned at the veutro portion A of diaper 10, and end regions junction surface 162B is positioned at drosal part B.In addition, end regions junction surface 162A, 162B are formed in the mode extended along the length direction of diaper 10.2 chip bondings are formed by utilizing known engagement means such as such as Re Mi or bonding agent etc. by end regions junction surface 162A, 162B.
The three-dimensional gathered elastomeric parts 161 extended along the length direction of diaper 10 are fixed on the free end of three-dimensional gauffer with extended state.Utilize the contractility of these three-dimensional gathered elastomeric parts 161, between end regions junction surface 162A, 162B, three-dimensional gauffer formation sheet 162 erects to the bodyside of wearer and forms three-dimensional gauffer.
At the stiff end than three-dimensional gauffer more by the position of width foreign side, three-dimensional gauffer formation sheet 162 engages with back sheet 23, is formed with a pair flank 24 thus.Flank 24 stretches out from the both side edges along its length of absorber 20 to width foreign side, and extends along the length direction of diaper 10.At flank 24, at the position roughly corresponding with crotch C, multiple side flap elastic parts 163 that leg creases is formed with extended state configuration in the longitudinal direction.Side flap elastic parts 163 are clamped between three-dimensional gauffer formation sheet 162 and back sheet 23.Utilize the contraction of side flap elastic parts 163, form leg creases at the crotch C of diaper 10.
The flexure strip 164 that waist gauffer is formed is configured with in the position of the length direction end of the drosal part B side of diaper 10.Multiple elastomeric element 165a, 165b that flexure strip 164 is configured to extend along the width of diaper 10 are clamped between 2 chip parts 164a, 164b with extended state.
In flexure strip 164, the waist elastic members 165b in multiple elastomeric element 165a, 165b configures in the mode extended in the width direction at the length direction end regions of the drosal part B of diaper 10.Specifically, waist elastic members 165b near the position of waist opening edge W, between the length direction ora terminalis of the drosal part B side of the length direction ora terminalis in drosal part B side and absorber 20.And then waist elastic members 165b is from the position near the side edge part the width of diaper 10 until the position near opposite side edge configures continuously.On the other hand, adjoin with waist elastic members 165b and be positioned at than waist elastic members 165b more by elastomeric element and the waist portion elastomeric element 165a of the position of crotch C, only be configured in the left and right sides portion of the width of diaper 10, the middle section of width becomes the state not configuring any elastomeric element.Specifically, waist portion elastomeric element 165a has one end near the side edge part of the width of diaper 10.The other end arrive to diaper 10 width middle section before stop.Therefore, there is not any elastomeric element at the middle section of width.
Absorber 20 is the shape of the lengthwise extended along the direction identical with the length direction of diaper 10 when overlooking, symmetrical about length direction centre line C L.Absorber 20 from the veutro portion A of diaper 10 until drosal part B configure.In absorber 20, the lateral margin about it is square bending in width at the middle section of length direction, namely corresponding with the crotch C of diaper 10 position.
Absorber 20 has the coating member of absorbent core 22 and this absorbent core 22 coated comprising high absorption polymer.Absorbent core 22, in drosal part B, is configured in the middle section of position, the i.e. width between above-mentioned waist portion elastomeric element 165a.Absorbent core 22 configures in not overlapping with waist portion elastomeric element 165a mode.That is, the lateral margin of absorbent core 22 is not arrived by the end of side in width in 2 ends of waist portion elastomeric element 165a.Absorbent core 22 is not overlapping with waist elastic members 165b yet.By making absorbent core 22 and waist portion elastomeric element 165a have as above configuration relation, the contractility of waist portion elastomeric element 165a not easily acts on absorbent core 22.In addition, the contractility of waist elastic members 165b is not vulnerable to absorbent core 22 and hinders.Thereby, it is possible to the generation etc. of the unexpected distortion effectively preventing absorbent core 22 or the conformable reduction caused thus and leak of liquid.
The X-X profile of the absorbent core 22 of the absorber 20 shown in Fig. 1 is represented in Fig. 3.As shown in the drawing, absorbent core 22 has first surface 223A and second 223B.First surface 223A is skin abutment face, towards positive dough sheet 21 or towards as required and use intermediate (not shown) side.Second 223B is non-skin abutment face side, towards back sheet 23 side.
Absorbent core 22 comprises: high grammes per square metre portion 234a, and its grammes per square metre (mass area ratio) is relatively high and have to the outstanding convex form in non-skin abutment face side; With low grammes per square metre portion 234b, itself and high grammes per square metre portion 234a are adjacent and grammes per square metre is relatively low, from non-skin abutment face side direction skin abutment face side depression.High grammes per square metre portion 234a and low grammes per square metre portion 234b is integrally formed.The non-skin abutment face side of absorbent core 22 is sag and swell, and skin abutment face side is smooth.When the non-skin abutment face side making absorbent core 22 is sag and swell, due to the width externally applied forces from absorber 20, absorber 20 is easily flexibly out of shape.Its result is, the conformable raising of diaper 10.So-called " integrally formed " refers to that these positions are inseparable not ground integrated each other via engagement means such as bonding agent or heat fuse, is formed by identical material.When these regions are integrated, having body fluid can the seriality of successfully movement.The manufacture method of the absorber of this kind of structure is described hereinafter.
Absorbent core 22 comprises liquid absorbent material.As liquid absorbent material, material same with the material that prior art uses in the technical field of absorbent commodity can be used in.Such as, the superabsorbent polymer comprising and separate fiber paper pulp or hydrogel material can be used.Absorbent core 22 is coated by the liquid permeability sheet comprising cotton paper or non-woven fabrics etc.
The top view observing absorbent core 22 from positive dough sheet 21 side is represented in Fig. 4.As shown in this figure and Fig. 1, multiple in low grammes per square metre portion 234b extend abreast with the length direction of absorbent core 22.In addition, multiple in low grammes per square metre portion 234b extend abreast with the width of absorbent core 22.Its result is, low grammes per square metre portion 234b is formed as the shape of the orthogonal lattice-shaped extended along length direction and the width of absorbent core 22.And high grammes per square metre portion 234a is positioned at the grid formed by low grammes per square metre portion 234b.Therefore, each high grammes per square metre portion 234a is by low grammes per square metre portion
In present embodiment, the high grammes per square metre portion 234a of structure agglomerated regions 235 is identical rectangular shape in veutro portion A, drosal part B and crotch C, but also can replace, the width making the rectangle of the high grammes per square metre portion 234a being positioned at veutro portion A is greater than the width of the rectangle of the high grammes per square metre portion 234a being positioned at crotch C with the width of the rectangle of the high grammes per square metre portion 234a being positioned at drosal part B.By adopting this kind of structure, the conformable of diaper 10 can be improved further.In addition, when adopting this structure, when the external force from width puts on absorber 20, distortion or the damage of high grammes per square metre portion 234a can also effectively be prevented.Result brings conformable raising.
As mentioned above, absorbent core 22 has block region 235, it has the block formed by relatively much higher the high grammes per square metre portion 234a of grammes per square metre and grammes per square metre relatively low low grammes per square metre portion 234b and constructs, and the surrounding of each high grammes per square metre portion 234a is surrounded by low grammes per square metre portion 234b throughout its whole region and independence separately.And then the most peripheral of block structure is surrounded by low grammes per square metre portion 234b.Be positioned at the bight of the low grammes per square metre portion 234b of the most peripheral of block structure preferably with the radian depicting the curve protruded outward.
By having the block region 235 comprising high grammes per square metre portion 234a and low grammes per square metre portion 234b, absorbent core 22 becomes soft at its length direction and this two side of width, and thus, absorber 20 becomes easily along the shape of the health of wearer.And then the liquid excreted is guided by the low grammes per square metre portion of thinner thickness and flows, and can improve the length direction of absorber 20 and the diffusibility of width thus.
