As shown in Figure 5 B, therefore, it is possible to rapidly from being in the under-weight lying prostrate posture shown in Fig. 5 A Baby 101 takes off diaper 1.I.e., as shown in Figure 5A, diaper 1 usually is such that and is fixed with fixing band 11 The mode of the dorsal part that the second waist portion 1b is positioned at SFD 101 is worn by SFD 101.Cause This, lie prostrate posture owing to being in, so the top that the second waist portion 1b is positioned on vertical direction.Utilize urine Cloth 1, it is possible to utilization is cut line 1c and cut the fixing band fixed part 1bk of the second waist portion 1b as described above (Fig. 5 B).This makes it possible to the lateral center portion 1bc of fixing band 11 with the second waist portion 1b separates (figure 6).This makes it possible in the case of male member 11m of fixing band 11 remains fixed to the first waist portion 1a Separate the first waist portion 1a and the second waist portion 1b, thus open diaper 1.This makes it possible to bow from being in The SFD 101 of volt posture takes off diaper 1.

With reference to Fig. 6, fix as it has been described above, cut the line 1c fixing band that is positioned in the second waist portion 1b The position of the laterally inboard of portion 1bk extends.When cutting fixed part 1bk, thus do not need to cut off admittedly Surely 11 are carried.This makes it possible to reduce the power necessary to 1c that rolls off the production line earnestly.Therefore, it is possible to reduce in the mistake cut Journey may apply the external force to SFD 101, this thought being applicable to minimize operation.

The perforation cutting line 1c is that the groove of one group of multiple linearity (is equivalent to through hole, at Fig. 6 and showing All figures of perforation are schematically shown).That is, through-thickness runs through what the second side flap 1bsf extended The groove (not shown) of multiple linearities is along cutting direction configuration to be extended for line 1c.In view of suitable Cuttability etc. design length and the pitch of groove.Specifically, the length of groove is illustrated as 1-3mm, phase The adjacent interval (in other words, the length of the part that there is not groove between groove) between groove is illustrated as 0.5-2mm.Can be said to, the pitch of aforementioned grooves is length and the sum at interval of groove.

To illustrate in further detail below to cut line 1c.

As shown in Figure 6, be formed at a second side flap 1bsf cut line 1c and be formed at another second The line 1c that cuts of side flap 1bsf is line symmetrical for the centrage C1 transversely about diaper 1.Respectively cut Line 1c substantially J-shape and by along longitudinal straight section 1cL and the curve-like of curved shape Part 1cB is constituted.

Straight section 1cL makees with part 1bHB as waist peristome 1HB of the second waist portion 1b For starting point；In other words, straight section 1cL using the longitudinally outer 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 arrives Reach the position in the longitudinal direction identical with fixing band 11 or arrive the position in identical longitudinal direction slightly inwardly 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 is to vertical Extending to inner side, curved surface portion 1cB bends to lateral outer side with specific curvature；Curved surface portion 1cB Eventually arrive at part 1bHL as leg-openings portion 1HL in the second waist portion 1b, i.e. eventually arrive at The ora terminalis 1be2 lateral out of the second waist portion 1b.

Utilize this path cutting line 1c, cut line 1c and surround fixing band fixed part from laterally inboard completely 1bk.When line 1c is cut in cut-out, fixing band fixed part 1bk together with fixing band 11 therefore, it is possible to the second waist The lateral center portion 1bc of body portion 1b separates.

If additionally, include aforementioned curved surface portion 1cB, then cutting line 1c and can follow relatively short road Footpath arrives the ora terminalis 1be2 lateral out of the second waist portion 1b.I.e., it is possible to do not make the path cutting line 1c to Longitudinal medial sets in the case of too much extending and cuts line 1c.This can be effectively prevented and cut line 1c's Path is contingent problem when longitudinal medial too much extends, and these problems e.g. all arrive in path During the first side flap 1asf (Fig. 2), the part cutting line 1c is trapped in the under-weight baby being in location posture The abdominal part of youngster 101 and user in the separate lower limb of M shape between, this makes it difficult to cut-out and cuts line 1c.

In the example of fig. 6, cut line 1c to be in the second side flap 1bsf.But, the invention is not restricted to This.I.e., in some cases, the part cutting line 1c can further extend into crotch side flap 1msf.But, excessive extension causes being difficult to cut off the problem cutting line 1c, this is because cut line 1c Easily be trapped in SFD 101 abdominal part and in the separate lower limb of M shape between, or because shearing length Longer.

In this example, the position of formation straight section 1cL it is in for multiple 4,5 and 6.Specifically, Following three sheet is there is: three-dimensional rivel sheet 6 from the skin side of thickness direction；Leakage prevention sheet 4；With outer load 5. The quantity of the sheet of stacking is 3.At straight section 1cL, therefore perforation is formed through the sheet 4,5 of stacking Extend with 6.

On the other hand, as it has been described above, the position of forming curves shape part 1cB is along with advancing to longitudinal medial And shift to lateral outer side.The quantity of the sheet of stacking therefore in the one end from curved surface portion 1cB to another The traveling process of end changes.In other words, as shown in the left side of Fig. 6, in the company of curved surface portion 1cB Receive part 1cB1 of the particular range of straight section 1cL, the quantity of the sheet of stacking and straight section 1cL is similarly 3.There is part 1cB1 with particular range of curved surface portion 1cB adjacent and be positioned at Part 1cB2 of the longitudinal medial of part 1cB1 of particular range, this part 1cB2 does not include leakage prevention sheet 4, But include three-dimensional rivel sheet 6 and 5 two kinds of sheets of outer load.Therefore, although perforation is in front portion 1cB1 In be formed through three sheets 4,5 and 6 extend, but perforation be formed through in rear portion 1cB2 Two sheets 5 and 6 extend.

When this part 1cB2 that the quantity of the lamination sheets also existed in curved surface portion 1cB is less, this portion 1cB2 is divided relatively easily to cut off.This can be conducive to the cut-out of curve, in general, cuts off curve ratio and cuts Disconnected straight line is difficult.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 it has been described above, cut line 1c to be formed at the second side flap 1bsf, respectively Cut the position that line 1c is both formed in the lateral outer side of absorber 3.As from Fig. 6 it can be seen that, cut line 1c is formed at the position of the lateral outer side of the base end part 6k and rising portions 6s of three-dimensional rivel sheet 6.

Therefore, even if tear fracture cuts line 1c, absorber 3 and the base end part 6k of three-dimensional rivel sheet 6 and vertical Play portion 6s not to be affected, remain sound.This effectively prevents by absorber 3 or rising portions 6s The Excreta kept is owing to cutting the leakage from diaper 1 that line 1c causes.

About the position relationship cut between line 1c and top flat 2, cut line 1c and be formed at top flat 2 lateral out , in other words, there is not top flat 2 in the position cutting line 1c in side.Sheet in the position stacking cutting line 1c Quantity thus less than other regions.This structure is favorably improved the easiness cutting line.

From being more beneficial for from the viewpoint of cut-out cuts line 1c, leakage prevention sheet 4 is preferably configured such that and is used as The resin molding of the leakage prevention sheet 4 in Fig. 6 bearing of trend during fabrication is along longitudinal direction.That is, it is orientated due to resin Consistent with bearing of trend, resin molding is usually cut readily along bearing of trend.If bearing of trend is along vertical To, then leakage prevention sheet 4 is therefore readily along longitudinally cutting.Therefore, it is possible to along longitudinally accurately cutting off existence The straight section 1cL of leakage prevention sheet 4.

As shown in Figure 6, cut the cut-out of the straight section 1cL of line 1c when continuing and cut off curved surface portion During 1cB, owing to cutting off the impetus of straight section 1cL, the most unexpectedly cut off straight section 1cL's Extended line or position near it.That is, there is the position away from curved surface portion 1cB by accidental amputation Probability.In order to prevent case above, use following way in this example.

Lower limb encloses elastic component 21 and is positioned at the vicinity cutting line 1c.As from thickness direction finding, lower limb encloses elastic structure Part 21 and the curved surface portion 1cB cutting line 1c intersect at specific crossover location P1c.More specifically, such as figure Shown in the right-hand part of 6, it is assumed that curved surface portion 1cB is divided into two parts, i.e. near waist peristome 1HB's Part 1cBa and part 1cBb near leg-openings portion 1HL, crossover location P1c is in and opens near waist Front portion 1cBa of oral area 1HB.Crossover location P1c the most relatively close straight section 1cL and curve Boundary position PLB between shape part 1cB.

The process of the curved surface portion 1cB cutting line 1c is cut off continuing the cut-out of straight section 1cL In, when off-position arrives near the crossover location P1c of boundary position PLB, cut off straight section 1cL is absorbed along longitudinal impetus owing to lower limb encloses the elastic deformation of elastic component 21.Along longitudinal direction Therefore the cut-out action of straight line stops.This makes it possible to quickly adjust the cut-out towards curved surface portion 1cB Position.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, cut the easiness of line 1c according to vertical To position and different.For example it is assumed that cut line 1c to be divided into part 1c1 of three longitudinal directions, 1c2 and 1c3, The easiness cutting line 1c sets corresponding to part 1c1,1c2 and 1c3.More specifically, three portions The Part I 1c1 (cutting line part corresponding to first) dividing one in 1c1,1c2 and 1c3 is positioned at bag Include the region of part 1bHB as waist peristome 1HB in the second waist portion 1b.This Part I 1c1 is constituted by holding scissile perforation.As another second in three parts 1c1,1c2 and 1c3 Part 1c2 (cutting line part corresponding to second) is positioned at and includes the position corresponding with fixing band fixed part 1bk Longitudinal direction on region.This Part II 1c2 is difficult to the easy cut-out cut off by the perforation than Part I 1c1 Perforation is constituted.Part III 1c3 as remaining part 1c3 is above-mentioned curved surface portion 1cB.This is years old Three parts 1c3 are made up of the perforation of easily cutting off that the perforation with Part I 1c1 is same type.

So easily cut through hole owing to Part II 1c2, effectively prevent Part II 1c2 in order to Wear diaper 1 to SFD 101 and unexpectedly disconnect when each fixing band of lateral outer side tractive 11,11. Additionally, when taking off diaper 1 from SFD 101, the perforation of easily cutting off of Part I 1c1 makes it possible to Enough easily start to cut diaper 1 from part 1bHB as waist peristome 1HB.Simultaneously owing to easily cutting Disconnected perforation and can be accurate along the aim curve shape of the curved surface portion 1cB as Part III 1c3 Ground cuts off curved surface portion 1cB.

The length being set by changing the groove being included in perforation of the above-mentioned easiness to cutting off perforation is come Realizing, this is used in this example.I.e., in this example, the pitch of groove maintains the identical and length of groove Degree difference.Therefore, the unit length of line 1c bearing of trend is cut on the length of the groove in part 1c2 and edge Ratio is different from the ratio in part 1c1,1c3.In general, the perforation with big ratio is easily cut off, The perforation with little ratio is difficult to cut off.Therefore, in this example, the ratio in Part II 1c2 is little Ratio in Part I 1c1 and the ratio in Part III 1c3.

In the figure 2 example, in each first side flap 1asf, 1asf of the first waist portion 1a, line of cut 1ca is made up of perforation.In other words, in each first side flap 1asf, line of cut 1ca is formed as from longitudinal direction External end edge 1asfe extends to longitudinal medial.The horizontal forming position of line of cut 1ca with cut line 1c Forming position on the longitudinally outer end edge 1bsfe of two side flap 1bsf is identical.

This makes relatively wide interval can be present between line of cut 1ca, the 1ca in the first waist portion 1a. Therefore, after cutting off the perforation of line of cut 1ca, 1ca, cut by folding the first being positioned at of waist portion 1a Part 1am between secant 1ca, 1ca, it is possible to expose the abdominal part of SFD 101.This is right at needs It is effective that the abdominal part of baby is carried out in the case of the suitable process such as all light treatment.Because cutting off After these lines of cut, line of cut 1ca, 1ca the most transversely open, so the first waist portion 1a can The most flexibly deform.The SFD 101 that abdominal part is big is therefore, it is possible to cosily wear diaper 1.

Fig. 8 is the explanatory diagram cutting line 1c ' of the first modified example.Although in the foregoing embodiment, such as Fig. 6 Shown in, the quantity of the sheet of stacking becomes 2 according to the position cutting line 1c from 3, but in the first modification In example, the quantity of the sheet of stacking is constant in the whole length respectively cut line 1c '.I.e., as shown in Figure 8, The horizontal stroke cutting line 1c that the position of line 1c ' is positioned in Fig. 6 of aforementioned embodiments is cut in the first modified example Laterally.In the whole length cutting line 1c ', cut the line 1c ' lateral outer side therefore in leakage prevention sheet 4. In this position, only exist two sheets: three-dimensional rivel sheet 6 and outer load 5.Further, the perforation of line 1c ' is cut Through-thickness runs through the two sheet 5 and 6 and is formed.The stacking sheet of lesser amt, it is thus possible to good Good cuttability cuts line 1c '.Remaining structure is roughly the same with the structure of aforementioned embodiments.With The parts that the parts of aforementioned embodiments are identical will be indicated by the same numbers, and eliminate it and say Bright.

Fig. 9 be the second modified example cut line 1c " explanatory diagram.In aforementioned embodiments and the first modified example In, as shown in Figure 6 and Figure 8, cut line 1c and 1c ' and all 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 include curved surface portion 1cB but only include Straight section 1cL.That is, in the second modified example, compared with the first modified example, line 1c is respectively cut " all It is positioned at lateral outer side.This single straight section 1cL made it possible to merely with extending longitudinally cuts Fixing band fixed part 1bk.This is utilized to cut line 1c ", only cut off single straight section 1cL and make it more hold Easily cut off.Therefore, it is possible to cut line 1c in the most significantly deviation " position carry out cutting off in the case of diaper 1 Accurately cut line 1c ".Respectively cutting line 1c " position, only exist two sheets: three-dimensional rivel sheet 6 With outer load 5.And cut line 1c " perforation through-thickness run through the two sheet 5 and 6 and formed.

Figure 10 be the 3rd modified example cut line 1c " ' explanatory diagram.Aforementioned embodiments (Fig. 6), In one modified example (Fig. 8) and the second modified example (Fig. 9), all cut line 1c, 1c ' and 1c " from second Part 1bHB as waist peristome 1HB of waist portion 1b is to the part as leg-openings portion 1HL 1bHL is J-shaped or linearity extends and formed.But, the 3rd modified example cut line 1c " ' mainly because of Such path is not used and different for these lines.I.e., as shown in Figure 10, line 1c is cut " ' be substantially U-shaped thus at three sides 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 side flap 1bsf of the second waist portion 1b, cuts line 1c " ' so that solid Determine band fixed part 1bk to be positioned at the mode of the substantially inner side in U-shaped path and extend from top, eventually arrive at and begin The horizontal outermost ora terminalis of the second side flap 1bsf that end Ps is identical；Cut line 1c " ' arrive outermost ora terminalis 1bsfee Position Pe be to cut line 1c " ' terminal.Remaining structure is roughly the same with the structure of aforementioned embodiments. The parts identical with the parts of aforementioned embodiments will be indicated by the same numbers, and eliminate it Explanation.

Incidentally, the beginning in description illustrates, the diaper 1 of present embodiment is applicable to 3000 grams Or less SFD 101.Furthermore, it is contemplated that diaper 1 can efficiently solve and position posture and Minimize the foregoing problems that operation is relevant.It is believed that diaper 1 patient easily be in location posture and With greater need for minimizing in the case of operation more effectively.This is the situation that the body weight of patient is less.
