Referring again to Fig. 2, each

fastener member

41a, 41b are mutually symmetrical, and fastener member 41b has the configuration identical with fastener member 41a, so will partly omit the explanation of fastener member 41b.Fastener member 41a comprises the 3rd non-woven fabrics 43, the 4th non-woven fabrics 44 and hook element 45, and have the inelastic region 46 that hook element 45 is mounted to Hookean region 33a, snap-region 47 comprises hook element 45 and along the horizontal outward extending finger of B, holds sheet (finger-grip tab) 48 from snap-region 47.The 3rd non-woven fabrics 43 and the 4th non-woven fabrics 44 are bonded to each other to be integrated and to form not tensile substrate sheets 40(and see Fig. 4).This third and fourth non-woven fabrics be preferably fiber number in the scope of 1dtex to 7dtex and/or mass area ratio at 25g/m ²to 60g/m ²thermoplastic synthetic fiber's the non-woven fabrics of scope.In each

fastener member

41a, 41b, for the 3rd non-woven fabrics 43 and the 4th non-woven fabrics 44 being bonded to each other in snap-region 47 and finger are held sheet 48, for in inelastic region 46 by the 4th non-woven fabrics 44 and the second non-woven fabrics 36 in conjunction with and in inelastic region 46 by the 3rd non-woven fabrics 43 and the first non-woven fabrics 34 combinations, can use hot-melt adhesive, or can each be bonded to each other to non-woven fabrics by compartment of terrain melting combination.Thus, in order to control reliably that the finger of fastener member 41a is held sheet 48 and/or in order to be conducive to operate hook element 45, the 3rd non-woven fabrics 43 and the 4th non-woven fabrics 44 are preferably bonded to each other, two non-woven fabrics should easily not peeled off each other, and substrate sheets 40 is preferably formed by the composite sheet with one or more following character: mass area ratio is at 50g/m ²to 120g/m ²scope, thickness is in the scope of 0.2mm to 0.5mm, and flexural rigidity is higher than the flexural rigidity of other elements in diaper 1.For this purpose, also can be combined with hot-melt adhesive and melting is bonded to each other the 3rd non-woven fabrics 43 and the 4th non-woven fabrics.The gauge of substrate sheets 40 is under atmospheric pressure, in the situation that there is no external force or pressure-acting to sheet, utilizes the value of kind of calliper.Hook element 45 is at least along horizontal B, to have the hook element of inextensibility, as hook element 45, can be used as the hook element being often known as such as the assembly of the mechanical snap part type of other trade marks such as Velcro (Velcro).And the quantity of hook in hook element 45 can suitably be selected, in a preferred embodiment, the quantity of hook element is longitudinal A and laterally on B in every 25mm length 30 to 50.In the diaper 1 shown in Fig. 2, when diaper 1 is through wearer with it time, the non-woven fabrics 12b in the outer housing 12 of hook element 45 and front waist region 7 engages, front waist region 7 and rear waist region 8 are connected to each other via lateral plate 31a, 31b.Non-woven fabrics 12b forms the effect that can play the loop member coordinating with hook element 45, thereby front waist region 7 and rear waist region 8 can be connected to each other separably.

Fig. 3 illustrates the Hookean region 33b of lateral plate 31b enlargedly, and partial cut is except the first non-woven fabrics 34.The second non-woven fabrics 36 in lateral plate 31b is for example coated with width dimensions at the hot-melt adhesive 38 of the scope of 7mm to 25mm, to form two sidepieces with the first adhesive region 51 that longitudinally A extends of the second non-woven fabrics 36.Between a pair of the first

adhesive region

51,51, the second non-woven fabrics 36 is coated with width dimensions and is preferably the S in the scope of 1mm to 5mm ₁multiple row hot-melt adhesive 38, to form multi-ribbon shape adhesive line 53 with preferably at the interval S of the scope of 1mm to 5mm ₂the second adhesive region 52 that longitudinally A extends.Lateral plate elastic component 37 has respectively the end 37a that is preferably installed to the second non-woven fabrics 36 with non-elongation state.Lateral plate elastic component 37 has respectively the pars intermedia 37b being limited between

end

37a, 37a, and pars intermedia 37b is mounted to the second non-woven fabrics 36 with the percentage elongation be scheduled to along the banded adhesive line 53 of the second adhesive region 52 under extended state.The first non-woven fabrics 34 is bonded to the second non-woven fabrics 36 in the first adhesive region 51 and the second adhesive region 52.The contraction that the Hookean region 33b forming by this way and lateral plate elastic component 37 occur in the 37b of portion is therebetween shunk in linkage, result, with Fig. 2 in the similar mode of situation of illustrative lateral plate Hookean region 33a form a plurality of wrinkle 39(and see Fig. 2).Thus, the coating pattern of the hot-melt adhesive 38 in illustrative lateral plate 31b can be applied to the first non-woven fabrics 34.Hot-melt adhesive 38 is suitable for making the first non-woven fabrics 34 to form longitudinally A a plurality of wrinkle 39 that extend parallel to each other, neat configuration, and hot-melt adhesive 38 is preferably applied to the first non-woven fabrics 34.

(a) of Fig. 4 usingd lateral plate 31a to (d), as example, the folding step of lateral plate 31a that diaper from Fig. 21 obtains the diaper 1 of Fig. 1 is shown.(a) of Fig. 4 is the sectional view along the intercepting of the line IV in Fig. 2-IV, wherein lateral plate 31a and fastener member 41a under smooth (expansions) state along laterally B extension.Hookean region 33a in lateral plate 31a is in contraction state and be formed with a plurality of folding lines 39 that rise and fall on horizontal B.In matrix 2, leakage-proof turnup 16a is poured on the state in absorption structure 13 in collapsing.In the side edge part 3a of matrix 2, a part of the installation portion 32a in lateral plate 31a is between forming the sheet material of leakage-proof turnup 16a and forming between the non-woven fabrics 12b of outer housing 12.These assemblies that overlap each other along the side edge part 3a of matrix 2 are preferably combined by hot-melt adhesive (not shown).Fastener member 41a is along first fold superimposing thread F ₁(see figure 2) is by arrow G ₁indicated direction, folding towards the inner face side of diaper 1, first fold superimposing thread F ₁in the inelastic region 46 of contiguous Hookean region 33a, longitudinally A extends.

In (b) of Fig. 4, the hook element 45 in folding fastener member 41a be formed on that wrinkle 39 on the inner surface of Hookean region 33a contact and temporarily and directly engage with the first non-woven fabrics 34 in strippable mode along a plurality of ridges of heaving towards hook element 45 of wrinkle 39.Yet hook element 45 is directly engaging with the first non-woven fabrics 34 with the separated ditch of hook element 45 along folding line 39 not.In the step of same (b) at Fig. 4, inelastic region 46 is along first fold superimposing thread F ₁folding, result inelastic region 46 is folded in half, and more preferably, inelastic region 46 is along fold line F ₁with himself close contact.In preferred fastener member 41a, in order to be decreased to as far as possible little thickness with the thickness of the inelastic region 46 of self close contact after doubling, through-thickness C compresses by E ₁, E ₂the region of indication.Region E ₁, E ₂be inelastic region 46 be positioned at first fold superimposing thread F ₁the partial section of two opposition sides.Under the folded state of hook element 45, region E ₁, E ₂along first fold superimposing thread F ₁extend and to first fold superimposing thread F ₁horizontal B inner side extend.Region E ₁, E ₂compression preferably under heated condition, carry out.Thus, compression preferably temperature corresponding at thermoplastic synthetic fiber's the softening temperature with forming respectively the 3rd non-woven fabrics 43 and the 4th non-woven fabrics 44 or that be less than this softening temperature is carried out, to prevent that these thermoplastic synthetic fibers from melting in the process of compression.Preferably, compression that should be under heated condition cause substrate sheets 40 along first fold superimposing thread F ₁forever fix, make substrate sheets 40 through wearer, with it, can maintain folded state in diaper 1 reality.In order to carry out this compression, can use surface temperature to be set as corresponding with softening temperature or lower than a pair of pressure roller R being indicated by dotted line of softening temperature ₁, R ₂.For example, when the 3rd non-woven fabrics and the 4th non-woven fabrics are the spun-bonded non-woven fabrics being formed by polypropylene monofilament, pressure roller R ₁, R ₂surface temperature can be set as 100 ℃ of temperature to 90 ℃ of scopes.As at this moment used, term " forever fixes " and refers to that substrate sheets by setting in heated condition lower compression can maintain the structure by setting in the state lower compression of heating under the state of room temperature or maintain the structure approximate with structure by setting in the state lower compression of heating removing compression and be cooled to.One of them dapple a pair of pressure roller R at least ₁, R ₂can be for compression, with at corresponding region E ₁and/or E ₂form embossing face, thereby prevent when substrate sheets 40 is at a pair of pressure roller R ₁, R ₂between by time may be at substrate sheets 40 and pressure roller R ₁, R ₂between the slippage that occurs.As region E ₁, E ₂during by hot compression, substrate sheets 40 is with respect to a pair of pressure roller R ₁, R ₂carefully located, to prevent that hook element 45 from being guided to a pair of pressure roller R mistakenly ₁, R ₂between and prevent that hook element 45 is compressed.In the step of same (b) at Fig. 4, as preferred embodiment, the region H in folding substrate sheets 40 is coated with the hot-melt adhesive 56 for following temporary transient combination or installation.Hot-melt adhesive 56 not only can be applied to substrate sheets 40, can also coat in a continuous manner substrate sheets 40 and lateral plate 31a.Yet hot-melt adhesive is preferably only coated substrate sheets 40, to prevent the contact skin as diaper 1 hot-melt adhesive 56 and wearer through with it wearer time.Substrate sheets 40 can be with 15g/m ²to 45g/m ²mass area ratio in scope, more preferably with 20g/m ²to 35g/m ²the coating weight coating hot-melt adhesive 56 of the mass area ratio in scope.Can be in 1mm to 5mm scope, more preferably in the width dimensions in the scope of 2mm to 3mm, be coated with hot-melt adhesive 56.On the horizontal B of fastener member 41a, hot-melt adhesive 56 and first fold superimposing thread F ₁preferably with 3mm at least, be spaced apart from each other in the horizontal.This is conducive to refer to hold apart from size the inelastic region 46 being folded in half.In the diaper 1 of coating that has completed hot-melt adhesive 56, along the second fold line F ₂by arrow G ₂indicated direction is towards the lateral plate 31a that inner face side is folding and fastener member 41a is overlapping.The second fold line F ₂longitudinally A(is shown in Fig. 2) the installation portion 32a of extend through lateral plate 31a.

In (c) of Fig. 4, the side edge part 3a of matrix 2, fastener member 41a and lateral plate 31a overlap each other, and side edge part 3a and fastener member 41a utilize temporary transient installation to be mounted to each other in strippable mode with hot-melt adhesive 56.Along the 3rd fold line F ₃by arrow G ₃indicated direction towards inner face side further the diaper 1 of state shown in folding (c) in Fig. 4 to reach the state shown in (d) of Fig. 4.The 3rd fold line F ₃unanimous on the whole with the lateral margin of absorbent structure 13 in the crotch region 9 of matrix 2, thereby longitudinally A(is shown in Fig. 2) extend through matrix 2.

In lateral plate 31a, fastener member 41a and the diaper 1 of matrix 2 in this folded state, then fold symmetrically lateral plate 31b, fastener member 41b and matrix 2 with lateral plate 31a, fastener member 41a and matrix 2, to reduce the size of diaper 1 on horizontal B.Also A folded diaper 1 longitudinally, makes front waist region 7 and crotch region 9 overlapping, and rear waist region 8 is overlapping with front waist region 7, to reach the state of the diaper 1 shown in Fig. 1.Thus, first, second, and third fold line F ₁, F ₂and F ₃it is the fold line not intersecting with hook element 45.

In folding in this way diaper 1, hook element 45 engages separably with wrinkle 39, therefore,

fastener member

41a, 41b are not easy to shake or be shifted in the process of manufacturing diaper 1, and Hookean region 33a, the 33b of

lateral plate

31a, 31b is not easy to extend and shrink in manufacture process.The semi-finished product that this measure is conducive to diaper 1 in the process of manufacturing diaper 1 with high-speed smooth transmit.Diaper 1 about nursing staff or auxiliary operation or unfolded, can expand the width of diaper 1 in accordance with (d) from Fig. 4 step by step to the reverse sequence of Fig. 4 (a), and

lateral plate

31a, 31b and

fastener member

41a, 41b are not easy to produce random behavior.Therefore, the diaper 1 of expansion can easily be smoothed out with the fingers direct join and rapidly on the body through wearer.In folding diaper 1, hook element 45 only temporarily engages with the ridge that is formed on the wrinkle 39 on

lateral plate

31a, 31b, this bonding area is less than hook element 45 and lateral plate 31a in flat condition, area under 31b temporary joint situation, therefore, hook element 45 can easily be peeled off from lateral plate 31a, 31b.Act in this way (a) that size N(on the horizontal B of each hook element 45 of

Hookean region

33a, 33b is shown in Fig. 4) can be set as being greater than (a) that size M(on the horizontal B of each

Hookean region

33a, 33b under relaxed state is shown in Fig. 4).Thus, in the situation that not departing from the scope of the present disclosure, size N can be identical with size M or be less than size M.When size N is less than size M, preferably by the first fold superimposing thread F of diaper 1 ₁position be chosen as and make, hook element 45 can be shown in Fig. 2 with the longitudinal axis P-P(of the close diaper 1 of Hookean region 33a) part engage, for example engage with edge, illustrative inner side 35 in (a) of Fig. 2 and Fig. 4.

In joining each fastener member 41a, the 41b of wrinkle 39 to, comprise region E ₁, E ₂in the interior part that is folded in half and is closely mounted to self, should automatically not reply flat condition, in the process of manufacturing diaper 1 and in the process of operation diaper 1, hook element 45 should not peeled off from wrinkle 39 accidentally yet.Comprise that the 3rd non-woven fabrics 43 that is mounted to each other and the inelastic region 46 of the 4th non-woven fabrics 44 preferably have 50g/m ²to 120g/m ²mass area ratio in scope and there is relatively high rigidity in diaper 1.Consider this point, when along first fold superimposing thread F ₁during the folding inelastic region 46 in flat condition, not only folding inelastic region 46, preferably also utilizes heated a pair of pressure roller R ₁, R ₂compression inelastic region 46, makes the substrate sheets 40 in fastener member 41a can be along fold line F ₁forever fix, to prevent that the fastener member 41a after folding from further returning back to flat condition before folding step.Region E ₁, E ₂in only folded and overlapping with self remainder of the inelastic region 46 that is folded in half and closely contacts with self and inelastic region compare and not only reduced thickness, and can utilize the figuratum side face of roller to stamp pattern.Like this, along first fold superimposing thread F ₁formed thickness little and avoided the finger of finger slippage problem to hold sheet.

In (c) of Fig. 4, fastener member 41a is mounted to matrix 2 with hot-melt adhesive 56 in strippable mode by temporary transient fixing, and therefore in the process of manufacturing diaper 1 or operation diaper 1, can easily maintain folded state.The hot-melt adhesive 56 of state shown in (c) in Fig. 4 should not hinder controlling of inelastic region 46 to folding.
