The material being suitable for use as three-dimensional rivel sheet 6 is illustrated as suitable non-woven fabrics, have employed SMS non-woven fabrics (spun-bonded non-woven fabrics/melt spraying non-woven fabrics/spun-bonded non-woven fabrics) in this example.But, the present invention is not limited thereto, as long as material softness.
As shown in Fig. 2, Fig. 3 A to Fig. 3 C, three-dimensional rivel sheet 6 extends to the position roughly the same with the external end edge of outer load 5 to lateral outer side; On preceding edge or near preceding edge, three-dimensional rivel sheet 6 and outer load 5 are formed as one by bonding or welding.By three-dimensional rivel sheet 6 together with outer load 5, aforementioned first flank sheet 1asf and the second flank sheet 1bsf is respectively formed at the first waist portion 1a and the second waist portion 1b.Same at crotch 1m, on preceding edge or near preceding edge, three-dimensional rivel sheet 6 and outer load 5 are formed as one by bonding or welding.Therefore crotch flank sheet 1msf, 1msf are formed as lying across from edge the specific region of horizontal inner side.
Each crotch flank sheet 1msf, 1msf form leg-openings portion 1HL together with a part of the first flank sheet 1asf and a part of the second flank sheet 1bsf when wearing diaper.That is, crotch flank sheet forms the part around the lower limb of SFD 101.In order to longitudinally contracted crotch flank sheet 1msf is to form lower limb rivel, rubber covered wire 21 longitudinally extends and utilizes the such as method such as bonding to be fixed to each crotch flank sheet 1msf, and the lower limb that rubber covered wire 21 is used as linearly extension along the longitudinal encloses elastic component 21.When extend lower limb enclose elastic component 21 loose time, crotch flank sheet 1msf is longitudinally to form multiple pleat, and the plurality of pleat becomes lower limb rivel.
As shown in Figure 3 B, in this example, lower limb encloses elastic component 21 between outer load 5 and three-dimensional rivel sheet 6, but the present invention is not limited thereto.Such as, lower limb encloses elastic component 21 and can bond to the non-skin side surface of outer load 5 or bond to the skin side surface of three-dimensional rivel sheet 6.
In this example, rubber covered wire 21 is used as lower limb and encloses elastic component 21, but the present invention is not limited thereto.Can elastic webbing be used, or the tensile non-woven fabrics or tensile film based on natural resiliency with extensibility can be used.
As shown in Figure 2, fixing band 11,11 is separately positioned on outer end 1bsfe2,1bsfe2 of the transverse direction of a pair second flank sheets 1bsf, 1bsf.Band base material (the tape base member) 11a of each fixing band 11 is transversely in the microscler banded sheet be made up of non-woven fabrics; An end transversely with base material 11a is fixed to a part of 1bk of the outer end 1bsfe2 of the second flank sheet 1bsf, and the other end transversely protrudes past the lateral outer side of the outer end 1bsfe2 of the second flank sheet 1bsf.
The public component 11m of hook-and-loop is fixed to the skin side surface of this ledge, and multiple fixation hook (not shown) are arranged at the skin side surface of public component 11m.Therefore the fixation hook of public component 11m hooks the target area 1at of the non-skin side surface being arranged on the first waist portion 1a, and fixing band 11 is fixed to the first waist portion 1a thus.Known hook-and-loop is suitable for use as public component 11m; Such as, the fixation hook of fishing hook form or T-shaped shape may suitably be adopted.
As shown in fig. 2 and fig. 3 a, target area 1at is in the non-skin side surface of outer load 5, is namely in the non-skin side surface of the first waist portion 1a.In other words, in this example, because outer load 5 is non-woven fabrics and can guarantee the performance that is enough to be fixed to public component 11m, so the non-skin side surface of outer load 5 itself is used as the target be fixed for public component 11m.But, the present invention is not limited thereto.Special object tape can be adopted to form target area 1at.
When wearing diaper 1 for SFD 101, by a pair fixing band 11,11 in the second waist portion 1b towards both lateral sides tractive diaper 1 the second waist portion 1b while, this is fixed to the target area 1at (Fig. 4) of the first waist portion 1a to each fixing band in fixing band 11,11.In the figure 2 example, band base material 11a protrudes past the lateral outer side of public component 11m, these ledges 11ap be used as towards during the both sides tractive of fixing band 11 by the grips 11ap gripped.
Be explained above the essential structure of diaper 1.In the present embodiment, in order to diaper 1 can be taken off from the SFD 101 of posture of lying prostrate being in Fig. 5 A, under the state expanding diaper 1 as shown in Figure 2, be formed respectively in second flank sheet 1bsf, 1bsf of the second waist portion 1b and cut line 1c, 1c.
Fig. 6 is the enlarged drawing for illustration of the major part of the present invention cutting line 1c.As shown in Figure 6, cut line 1c and be set in the manner of perforations, the part 1bk that the band base material 11a for fixing band 11 making it possible to cut the second waist portion 1b fixes is (by the part 1bk of the shadow representation in Fig. 6; Hereinafter referred to as fixing band fixed part 1bk).More specifically, cut line 1c to be respectively formed in the second flank sheet 1bsf corresponding with each fixing band 11.Respectively cut line 1c to be formed as extending to the part 1bHL as leg-openings portion 1HL from the part 1bHB as waist peristome 1HB through the position of the laterally inner side being positioned at fixing band fixed part 1bk in the second waist portion 1b.
As shown in Figure 5 B, therefore, it is possible to take off diaper 1 from being in the SFD 101 of posture of lying prostrate shown in Fig. 5 A rapidly.That is, as shown in Figure 5A, diaper 1 is worn by SFD 101 in the mode making the second waist portion 1b being fixed with fixing band 11 be positioned at the dorsal part of SFD 101 usually.Therefore, posture is lain prostrate owing to being in, so the second waist portion 1b is positioned at the top on vertical direction.Utilize diaper 1, can utilize as described above and cut the fixing band fixed part 1bk (Fig. 5 B) that line 1c cuts the second waist portion 1b.This makes it possible to the lateral center portion 1bc of fixing band 11 with the second waist portion 1b to be separated (Fig. 6).This makes it possible to be separated the first waist portion 1a and the second waist portion 1b when the public component 11m of fixing band 11 remains fixed to the first waist portion 1a, thus opens diaper 1.This makes it possible to lie prostrate the SFD 101 of posture take off diaper 1 from being in.
With reference to Fig. 6, as mentioned above, cut the position that be positioned at the laterally inner side of fixing band fixed part 1bk of line 1c in the second waist portion 1b to extend.When cutting fixed part 1bk, thus do not need to cut off fixing band 11.This makes it possible to reduce to roll off the production line earnestly the necessary power of 1c.Therefore, it is possible to reduce the external force that may be applied to SFD 101 in the process of cutting, this is applicable to the thought minimizing operation.
The perforation of cutting line 1c be the groove of one group of multiple linearity (be equivalent to through hole, Fig. 6 and show perforation all figure in be schematically shown).That is, the groove (not shown) that through-thickness runs through multiple linearities that the second flank sheet 1bsf extends configures along cutting the direction that line 1c will extend.Consider that suitable cuttability etc. designs length and the pitch of groove.Specifically, the length of groove is illustrated as 1-3mm, and the interval (length that there is not the part of groove in other words, between groove) between adjacent groove is illustrated as 0.5-2mm.Can be said to, the pitch of aforementioned grooves be the length of groove and interval and.
To illustrate in further detail below and cut line 1c.
As shown in Figure 6, be formed at a second flank sheet 1bsf cut line 1c and be formed at another the second flank sheet 1bsf cut the line that line 1c is the centrage C1 symmetry transversely about diaper 1.Respectively cut line 1c be roughly J-shaped shape and be made up of the curved surface portion 1cB of straight section 1cL along the longitudinal and curved shape.
Straight section 1cL is using the part 1bHB being used as waist peristome 1HB of the second waist portion 1b as starting point; In other words, straight section 1cL is using the longitudinal external end edge 1be1 in the second waist portion 1b as starting point.Then, straight section 1cL extends along being parallel to longitudinal straight line to longitudinal medial, and the position arrived in the longitudinal direction identical with fixing band 11 or the position that arrives in identical longitudinal direction are slightly to interior position.The position that straight section 1cL arrives at straight section 1cL is connected to curved surface portion 1cB.Curved surface portion 1cB extends to longitudinal medial further.More specifically, along with curved surface portion 1cB extends to longitudinal medial, curved surface portion 1cB bends to lateral outer side with specific curvature; Curved surface portion 1cB finally arrives the part 1bHL being used as leg-openings portion 1HL in the second waist portion 1b, that is, the final lateral outer ends edge 1be2 arriving the second waist portion 1b.
Utilize this path of cutting line 1c, cut line 1c and surround fixing band fixed part 1bk completely inside laterally.When line 1c is cut in cut-out, fixing band fixed part 1bk together with fixing band 11 therefore, it is possible to be separated with the lateral center portion 1bc of the second waist portion 1b.
In addition, if comprise aforementioned curved surface portion 1cB, then cut line 1c and can follow the lateral outer ends edge 1be2 that relatively short path arrives the second waist portion 1b.That is, can set when not making the path of cutting line 1c too much extend to longitudinal medial and cut line 1c.This can prevent the contingent problem when the path of cutting line 1c too much extends to longitudinal medial effectively, these problems are such as (Fig. 2) when all arriving the first flank sheet 1asf in path, between the abdominal part that the part cutting line 1c is trapped in the SFD 101 being in location posture and the lower limb separated in M shape of user, this makes to be difficult to cut-out and cuts line 1c.
In the example of fig. 6, cut line 1c to be in the second flank sheet 1bsf.But, the present invention is not limited thereto.That is, in some cases, the part cutting line 1c can extend to crotch flank sheet 1msf further.But excessive extension causes being difficult to cut off the problem cutting line 1c, be easily trapped between the abdominal part of SFD 101 and the lower limb separated in M shape this is because cut line 1c, or because shearing length is longer.
In this example, the position forming straight section 1cL is in for multiple 4,5 and 6.Particularly, there are following three sheets from the skin side of thickness direction: three-dimensional rivel sheet 6; Leakage prevention sheet 4; With outer load 5.The quantity of stacked sheet is 3.At straight section 1cL, therefore perforation is formed as running through stacked sheet 4,5 and 6 and extends.
On the other hand, as mentioned above, the position of forming curves shape part 1cB is shifted to lateral outer side along with advancing to longitudinal medial.Therefore the quantity of stacked sheet change in the traveling process from one end of curved surface portion 1cB to the other end.In other words, as shown in the left side of Fig. 6, at the part 1cB1 being connected to the particular range of straight section 1cL of curved surface portion 1cB, quantity and the straight section 1cL of stacked sheet are similarly 3.There is the adjacent with the part 1cB1 of particular range of curved surface portion 1cB and be positioned at the part 1cB2 of the longitudinal medial of the part 1cB1 of particular range, this part 1cB2 does not comprise leakage prevention sheet 4, but comprises three-dimensional rivel sheet 6 and outer load 5 two kinds of sheets.Therefore, extend although perforation is formed as running through three sheets 4,5 and 6 in front portion 1cB1, perforation is formed as running through two sheets 5 and 6 and extends in rear portion 1cB2.
As this part 1cB2 that the quantity that there is the lamination sheets in curved surface portion 1cB is less, this part 1cB2 relatively easily cuts off.This can be conducive to the cut-out of curve, and in general, it is more difficult than cutting off straight line to cut off curve.Therefore, it is possible to accurately cut off curved surface portion 1cB along aim curve shape.
In this example, with reference to Fig. 6, as mentioned above, cut line 1c and be formed at the second flank sheet 1bsf, respectively cut the position that line 1c is all formed in the lateral outer side of absorber 3.As found out from Fig. 6, cut the position that line 1c is formed in the base end part 6k of three-dimensional rivel sheet 6 and the lateral outer side of rising portions 6s.
Therefore, even if tear fracture cuts line 1c, base end part 6k and the rising portions 6s of absorber 3 and three-dimensional rivel sheet 6 be not also affected, and remains sound.This effectively prevents the leakage from diaper 1 that the Excreta that kept by absorber 3 or rising portions 6s causes owing to cutting line 1c.
About the position relationship cut between line 1c and top flat 2, cut the lateral outer side that line 1c is formed in top flat 2, in other words, there is not top flat 2 in the position of cutting line 1c.Therefore the quantity of the sheet stacked in the position of cutting line 1c be less than other regions.This is configured with and helps improve the easiness cutting line.
Cut line 1c from the view point of being more conducive to cutting off, the resin molding that leakage prevention sheet 4 is preferably arranged so that the leakage prevention sheet 4 be used as in Fig. 6 bearing of trend during fabrication along the longitudinal.That is, because resin orientation is consistent with bearing of trend, resin molding is usually easy to be cut along bearing of trend.If bearing of trend along the longitudinal, then therefore leakage prevention sheet 4 is easily cut along the longitudinal.Therefore, it is possible to accurately cut off the straight section 1cL that there is leakage prevention sheet 4 along the longitudinal.
As shown in Figure 6, when cutting the cut-out of the straight section 1cL of line 1c when continuing and cut off curved surface portion 1cB, owing to cutting off the impetus of straight section 1cL, easily unexpectedly cut off extended line or the position near it of straight section 1cL.That is, there is position away from curved surface portion 1cB by the probability of accidental amputation.In order to prevent above situation, adopt following way in this example.
Lower limb encloses elastic component 21 and is positioned at and cuts near line 1c.As from thickness direction finding, lower limb encloses elastic component 21 and intersects at specific crossover location P1c with the curved surface portion 1cB cutting line 1c.More specifically, as shown in the right-hand part of Fig. 6, assuming that curved surface portion 1cB is divided into two parts, namely near the part 1cBa of waist peristome 1HB and the part 1cBb near leg-openings portion 1HL, crossover location P1c is in the front portion 1cBa near waist peristome 1HB.Crossover location P1c is therefore relatively near the boundary position PLB between straight section 1cL and curved surface portion 1cB.
Continuing the cut-out of straight section 1cL and cut off in the process of the curved surface portion 1cB cutting line 1c, when off-position arrives the crossover location P1c near boundary position PLB, the impetus longitudinally cutting off straight section 1cL is absorbed because lower limb encloses the elastic deformation of elastic component 21.Therefore the cut-out action of straight line along the longitudinal stops.This makes it possible to the off-position of rapid adjustment towards curved surface portion 1cB.This makes it possible to accurately cut off diaper along curved surface portion 1cB.
In the example in figure 7, due to the way about perforation, the easiness cutting line 1c is different according to the position of longitudinal direction.Such as, assuming that cut part 1c1,1c2 and 1c3 that line 1c is divided into three longitudinal directions, the easiness cutting line 1c corresponds to part 1c1,1c2 and 1c3 and sets.More specifically, the Part I 1c1 (cutting line part corresponding to first) of in three part 1c1,1c2 and 1c3 is arranged in the region being used as the part 1bHB of waist peristome 1HB comprising the second waist portion 1b.This Part I 1c1 is formed by holding scissile perforation.Part II 1c2 (cutting line part corresponding to second) as another in three part 1c1,1c2 and 1c3 is positioned at the region in the longitudinal direction comprising the position corresponding with fixing band fixed part 1bk.The easy cut-out perforation that this Part II 1c2 is difficult to cut off by the perforation than Part I 1c1 is formed.Part III 1c3 as remaining part 1c3 is above-mentioned curved surface portion 1cB.By being identical type with the perforation of Part I 1c1, easy cut-out perforation is formed this Part III 1c3.
Easily cut perforation like this owing to Part II 1c2, effectively prevent Part II 1c2 in order to wear diaper 1 to SFD 101 and each to lateral outer side tractive fixing band 11,11 time unexpectedly disconnect.In addition, when taking off diaper 1 from SFD 101, the easy cut-out perforation of Part I 1c1 makes it possible to easily from being used as the part 1bHB of waist peristome 1HB, cut diaper 1.Can accurately cut off curved surface portion 1cB along the aim curve shape of the curved surface portion 1cB being used as Part III 1c3 owing to easily cutting off perforation simultaneously.
The setting of the above-mentioned easiness to cutting off perforation is realized by the length changing the groove be included in perforation, and this is used in this example.That is, in this example, the pitch of groove remains identical and the length of groove different.Therefore, the length of the groove in part 1c2 and different along the ratio cut in the ratio of unit length of line 1c bearing of trend and part 1c1,1c3.In general, the perforation with large ratio is easily cut off, and the perforation with little ratio is difficult to cut off.Therefore, in this example, the ratio in Part II 1c2 is less than the ratio in Part I 1c1 and the ratio in Part III 1c3.
In the figure 2 example, in each first flank sheet 1asf, 1asf of the first waist portion 1a, line of cut 1ca is made up of perforation.In other words, in each first flank sheet 1asf, line of cut 1ca is formed as extending from longitudinal external end edge 1asfe to longitudinal medial.The forming position of the transverse direction of line of cut 1ca is identical with cutting the forming position of line 1c on longitudinal external end edge 1bsfe of the second flank sheet 1bsf.
This make relatively wide interval can be present in the first waist portion 1a between line of cut 1ca, 1ca.Therefore, after the perforation cutting off line of cut 1ca, 1ca, by the part 1am between line of cut 1ca, 1ca of folding first waist portion 1a, the abdominal part of SFD 101 can be exposed.This is effective when needing when carrying out the suitable process such as all light treatment to the abdominal part of baby.Because after these lines of cut of cut-out, line of cut 1ca, 1ca easily transversely open, so the first waist portion 1a can transversely flexibly be out of shape.The SFD 101 that abdominal part is large is therefore, it is possible to cosily wear diaper 1.
Fig. 8 is the key diagram cutting line 1c ' of the first modified example.Although in the foregoing embodiment, as shown in Figure 6, the quantity of stacked sheet becomes 2 according to the position of cutting line 1c from 3, and in the first modified example, the quantity of stacked sheet is constant in the whole length respectively cutting line 1c '.That is, as shown in Figure 8, the position of cutting line 1c ' in the first modified example is arranged in the lateral outer side cutting line 1c of Fig. 6 of aforementioned embodiments.In the whole length cutting line 1c ', cut the lateral outer side that line 1c ' is therefore positioned at leakage prevention sheet 4.In this position, only there are two sheets: three-dimensional rivel sheet 6 and outer load 5.Further, the perforation through-thickness cutting line 1c ' runs through these two sheets 5 and 6 and is formed.The stacked sheet of lesser amt, thus can cut line 1c ' with good cuttability.Remaining structure is roughly the same with the structure of aforementioned embodiments.The parts identical with the parts of aforementioned embodiments represent by identical Reference numeral, and eliminate its explanation.
Fig. 9 be the second modified example cut line 1c " key diagram.In aforementioned embodiments and the first modified example, as shown in Figure 6 and Figure 8, cut line 1c and 1c ' and include straight section 1cL and curved surface portion 1cB.On the other hand, in the second modified example, respectively cut line 1c and " do not comprise curved surface portion 1cB but only comprise straight section 1cL.That is, in the second modified example, compared with the first modified example, respectively cut line 1c and " be all positioned at lateral outer side.This makes it possible to only utilize the single straight section 1cL extended longitudinally to cut fixing band fixed part 1bk.This is utilized to cut line 1c ", only cut off single straight section 1cL and make it more easily cut off.Therefore, it is possible to cut line 1c " position carry out cut-out diaper 1 accurately cut line 1c " when departing from not significantly.Respectively cutting line 1c " position, only exist two sheets: three-dimensional rivel sheet 6 and outer load 5.And cut line 1c " perforation through-thickness run through these two sheets 5 and 6 and formed.
Figure 10 be the 3rd modified example cut line 1c " ' key diagram.In aforementioned embodiments (Fig. 6), the first modified example (Fig. 8) and the second modified example (Fig. 9), allly cutting line 1c, 1c ' and 1c " be J-shaped from the part 1bHB being used as waist peristome 1HB of the second waist portion 1b to the part 1bHL being used as leg-openings portion 1HL or linearity extension and being formed.But, the cutting line 1c " ' main because these lines do not adopt such path and different of the 3rd modified example.That is, as shown in Figure 10, line 1c is cut " ' be roughly U-shaped thus at three gussets around fixing band fixed part 1bk.For respectively cutting line 1c " '; its top Ps is positioned at the horizontal outermost ora terminalis 1bsfee of the second flank sheet 1bsf of the second waist portion 1b; cut line 1c " ' extend from top in the mode making fixing band fixed part 1bk be positioned at the inner side in roughly U-shaped path, the final horizontal outermost ora terminalis arriving the second flank sheet 1bsf identical with top Ps; Cut the terminal of line 1c " the position Pe of ' arrival outermost ora terminalis 1bsfee cuts line 1c " '.Remaining structure is roughly the same with the structure of aforementioned embodiments.The parts identical with the parts of aforementioned embodiments represent by identical Reference numeral, and eliminate its explanation.
Incidentally, describe in the beginning of description, the diaper 1 of present embodiment is applicable to the SFD 101 of 3000 grams or less.In addition, consider that diaper 1 effectively can solve and locates posture and minimize and operate relevant foregoing problems.Can think that diaper 1 is more effective when patient is easily in location posture and more needs to minimize operation.This is the situation that the body weight of patient is less.
Therefore, the diaper 1 of present embodiment is preferably applicable to 500 grams or larger and is less than the LBWI of 2500 grams, more preferably be applicable to 1000 grams or larger and be less than the extremely low birth weight baby of 1500 grams, being further preferably applicable to the ULBW baby being less than 1000 grams.
The diaper 1 of present embodiment is specifically designed to SFD 101, is less than existing ewborn infant diaper 1.Such as, although the product length of ewborn infant diaper is 365mm and the perimeter L 1HB of its waist peristome 1HB is 304mm when being worn, the product length L1 (Fig. 2) of the diaper 1 of present embodiment perimeter L 1HB of its waist peristome 1HB for 210-330mm and when being worn is 160-295mm.
Such as, the product length L1 of diaper 1 is measured under the state be unfolded at diaper 1.That is, as shown in Figure 2, in deployed condition, first fixing band 11,11 is removed fixing from target area 1at.Then, launch diaper 1, first waist portion 1a, crotch 1m and the second waist portion 1b are longitudinally configured, and diaper 1 is longitudinally stretched to three-dimensional rivel sheet 6 and there is not contraction because three-dimensional rivel elastic component 6r causes and crotch flank sheet 1msf, 1msf do not exist because lower limb encloses the degree of the contraction that elastic component 21,21 causes.Then, longitudinal greatest length L1 of the diaper 1 after extending is measured; Measured value is product length L1.
On the other hand, when to make the mode of fixing band overlap fix a pair fixing band 11,11, measure the perimeter L 1HB of waist peristome 1HB.Figure 11 is its key diagram.For the purpose of illustrating, the fixing band 11 of the second flank sheet 1bsf in the left side in Figure 11 is hereinafter referred to as " left side band 11-1 ", and the fixing band 11 of the second flank sheet 1bsf on same right side is hereinafter referred to as " right side band 11-2 ".
Before measuring, first two fixing band 11-1 and 11-2 are fixed to make the mode of fixing band 11-1 and 11-2 overlap.That is, as shown in figure 11, the public component 11m of left side with 11-1 is fixed to the target area 1at of the first waist portion 1a, then the public component 11m of right side with 11-2 is fixed to the non-skin side surface 11-1s of left side band 11-1.Now, when being with longitudinal middle position C11-2 of longitudinal middle position C11-1 of 11-1 and band 11-2 to overlap, these bands are located so that the right side band edge 11-2e of 11-2 overlaps with the edge 11me of the root side of the public component 11m of left side band 11-1.Like this, to make the mode of fixing band overlap fix fixing band.
The waist peristome 1HB formed by fixing fixing band is stretched to till the contraction caused due to waistline elastic component 21 just eliminates.When extending waist peristome 1HB in like fashion, measure the perimeter L 1HB of waist peristome 1HB; Obtain perimeter L 1HB thus.
