On the other hand, as shown in Figure 5 and Figure 6, veutro band member 20a and dorsal part band member 20b are long in the horizontal It is in plan view the flat member of rectangular shape, and as shown in Figure 7 A, component is included in being laminated on thickness direction Outer-skin sheet 21 (correspond to first piece) and inner layer piece 22 (corresponding to second).It should be noted that inner layer piece 22 be located at than Position of the outer-skin sheet 21 by the skin side on thickness direction.Additionally, the flexible sheets shape of piece 21,22 both of which by non-woven fabrics etc. Into, and in this example, use spun-bonded non-woven fabrics.However, being not limited to the above, it is possible to use different types of non-woven fabrics, or Person is it is possible to further use resin film or spinning cloth etc..Additionally, in this example, using the independent fibre of polypropylene (PP) Tie up as the composition fiber of non-woven fabrics, but be not limited to the above, it is possible to use other thermoplastic resins of polyethylene etc. Individual fibers, or it is possible to further use the composite fibre of the sheath and core structures with polyethylene and PP etc..

Additionally, as shown in figure 5, middle section 20ac, 20bc in the horizontal of each band member 20a, 20b by with absorption The non-skin side of each end 10ea, 10eb in the vertical of property main body 10 is stacked together and engages.

I.e., in this example, as shown in Figure 5 and Figure 8, the planar dimension of outer-skin sheet 21 be from inner layer piece 22 towards longitudinal direction on Size protruding outside, and from outer-skin sheet 21 protrude part 21p while being turned back towards the inner side on longitudinal direction, from thickness Skin side on degree direction covers the end 22e in the vertical of inner layer piece 22, but is not limited to the above.

By the way, band member 20a, 20b is endowed retractility in the horizontal so that when diaper 1 is worn, and component can Firmly hold the waist of wearer.However, as described above, from prevent absorbent main body 10 absorbency or anti-leakage reduction Viewpoint is set out, as shown in fig. 6, the hardly non-telescoping region AL with retractility is formed at being particularly for band member 20a, 20b In region 20ac, 20bc Chong Die with the absorbent core 11 of absorbent main body 10.

As will be detailed below, veutro band member 20a and dorsal part band member 20b here have substantially identical to one another Structure.Therefore, in the following description, veutro band member 20a is only illustrated, and omits the explanation of dorsal part band member 20b.Additionally, In order to illustrate, hereinafter, as shown in the schematic plan view in Fig. 9, veutro band member 20a is divided into Liang Ge areas in the vertical Domain AU, AD are simultaneously illustrated.That is, the region AU positioned at waist opening 1HB sides in the vertical is referred to as " upper area AU ", and position Region AD in leg opening 1HB sides is referred to as " lower area AD ".

As shown in figure 9, absorbent cores 11 of the upper area AU generally with absorbent main body 10 be not overlap.Therefore, it is same Region AU is by the endlong imparting retractility in transverse direction.It should be noted that by that will be used as in the horizontal in elongation Multiple rubber threads 25,25 ... of the multiple thread elastic component along landscape configuration of state are abreast fixed to area in the vertical The imparting of retractility is realized in the AU of domain, and is for example performed using the hot-melt adhesive for coating rubber thread 25 or region AU The fixation of rubber thread 25 and region AU.In other words, the fiber number (fineness) of rubber thread 25 can be illustrated as example 470dtex-940dtex, and further, as the specific example of rubber thread 25, such as LYCRA (trade mark) can be illustrated Deng.It should be noted that above-mentioned setting is same for the rubber thread 27 for being arranged at lower area AD that will illustrate after a while.

On the other hand, lower area AD middle section ADc in the horizontal and absorbent main body 10 absorbent core 11 overlap, therefore middle section ADc is formed with the non-telescoping region AL of the retractility hardly having in transverse direction (corresponding to flatness Contracting region).Additionally, absorbent core 11 generally with the major part of each side region ADe, ADe of centrally located region ADc both sides Do not overlap, therefore in side region ADe, ADe, form the stretching region with the retractility higher than non-telescoping region AL AH, AH (correspond to stretching region high).

Here, the non-telescoping region AL of middle section ADc and stretching for each side region ADe, ADe are formed as follows Region AH, AH.First, as shown in Figure 10, using as be in the horizontal elongation state along horizontal multiple thread elasticity Multiple rubber threads 27,27 ... of component are abreast configured between outer-skin sheet 21 and inner layer piece 22 in the vertical.Additionally, using heat Substantially be fixed on each rubber thread 27 in the region AH1 corresponding to the stretching region AH in the ADe of side region by hot melt adhesive, And be not fixed in the region AL1 corresponding to the non-telescoping region AL in middle section ADc substantially.Therefore, corresponding to non- Both sides in the region AL1 of stretching region AL using appropriate cramping component (not shown) from thickness direction clamp band member 20a, and in this way, when each rubber thread 27,27 ... are cut off, as shown in figure 9, cut-off rubber thread 27,27 ... directions Side in transverse direction is shunk, and is generally not left in corresponding to the region AL1 of the non-telescoping region AL in middle section ADc In, but generally stay in the region AH1 corresponding to the stretching region AH in the ADe of side region.Therefore, in middle section Non-telescoping region AL is formd in ADc, stretching region AH is formd in the ADe of side region.

It should be noted that, using position PC, PC ... place that component is clamped is clamped, crimping outer-skin sheet along with cut-out 21 and inner layer piece 22, wire pressure contact portion j, j ... that the position PC being thusly-formed on longitudinal direction offsets one from another.Using pressure contact portion j, Position PC does not form through hole substantially, as a result can suppress what band member 20a may be caused along with the cut-out of rubber thread 27 Damage.Additionally, as shown in the schematic plan view in Figure 11, in this example, being formed with as the straight of wire pressure contact portion j, j ... Wire pressure contact portion j, j ..., and length Lj selects from the scope of such as 4mm to 30mm, width Wj from such as 0.1mm to Selected in the scope of 0.5mm.Using the length Lj scopes of pressure contact portion, as illustrated by after a while at the end of this specification, when When a wire pressure contact portion j cuts off 2 or 3 multiple rubber threads of grade 27,27 ... (reference picture 15), can be positively Cut off.However, wire pressure contact portion j be not in any way limited to it is above-mentioned linear, for example, it may be tortuous wire, or It can be the curve-like of circular arc wire etc..

Additionally, in order to solve problem of the invention as described above, being solution " by making wire pressure contact portion j, j ... The deterioration or suppression of the outward appearance of band member 20a are inhibited in moderate size scope less wide or not too narrow in the horizontal Made contact band member 20a when sticky feeling " problem, based on several rules formed wire pressure contact portion j, j ..., this will be under Face explanation.That is, in the Figure 11 that will be used in this manual, in order that the position relationship in transverse direction easily compares, also with two point Line shows parallel lines in the vertical, similarly, in order that the position relationship on longitudinal direction easily compares, is also shown with double dot dash line Go out parallel lines in the horizontal.

First, as shown in figure 11, in the lower area AD before rubber thread 27 is cut off, along horizontal rubber thread 27 So that there are appropriate intervals between rubber thread 27 adjacent in the vertical, example as multiple silks is abreast configured with the vertical 11 silks.In this example, for each rubber thread 27 in the horizontal one at PC perform these rubber threads 27,27 ... Cut-out.That is, using it is above-mentioned it is unshowned clamp component in the horizontal one at PC through-thickness clamp and cut off each rubber thread 27。

Therefore, it is respectively relative to each rubber thread 27,27 ... and forms a wire pressure contact portion for being accompanied by cut-out formation j、j….Specifically, in the example of fig. 11,11 rubber threads 27,27 ... are configured at lower area AD, therefore utilization clamps structure Part performs cramping and cuts off at 11 position PC, as a result, form the quantity identical sum of quantity and rubber thread 27,27 ... It is 11 wire pressure contact portion j, j ....By this way, clamped at component two or more position in the horizontal compared to utilization The situation of each rubber thread 27 is clamped, can make to be formed at the quantity of linear pressure contact portion j, j ... of the lower area AD of band member 20a It is few, as a result can effectively prevent from becoming the lower area AD of band member 20a due to the formation of wire pressure contact portion j, j ... Firmly.

In other words, this 11 wire pressure contact portions j, j ... position in the horizontal offsets one from another, but in order to illustrate, in figure In 11, new reference j1-j11 is distributed into 11 wire crimping with putting in order for the side from transverse direction to opposite side Each in portion j, j ....

On the other hand, when next rule/rule is illustrated, in this example of Figure 11, at least one wire pressure contact portion j At least another wire pressure contact portion j has the part for overlapping each other in the horizontal and the part not overlapped each other.

For example, in the case of two wire pressure contact portions j1, j2 in paying close attention to Figure 11, wire pressure contact portion j1 have with Part j1L that another wire pressure contact portion j2 is overlapped in the horizontal and with the nonoverlapping parts of another wire pressure contact portion j2 j1N.Similarly, another wire pressure contact portion j2 also have the part j2L overlap in the horizontal with wire pressure contact portion j1 with And with a nonoverlapping part j2N of wire pressure contact portion j1.

Using the relation of above-mentioned overlap, at least two wire pressure contact portion j1, the j2 for now paying close attention to can be effectively prevented from such as Fig. 2 B are excessively densely configured or excessively dispersedly configured as shown in Figure 3 like that.As a result, it is possible to by these wire pressures of interest Socket part j1, j2 is placed in appropriate width range in the horizontal.This helps for all wire pressure contact portion j, j ... to be placed on transverse direction On moderate size scope in.

Therefore, in this example, not only this overlap is formed to two wire pressure contact portions j1, j2 having paid close attention to before to close System, but also to being formed at all wire pressure contact portion j, j ... this overlapping relation of formation of lower area AD.

For example, in the case of two wire pressure contact portions j2, j3 in paying close attention to Figure 11, wire pressure contact portion j2 have with Part j2L1 that another wire pressure contact portion j3 is overlapped in the horizontal and with the nonoverlapping parts of another wire pressure contact portion j3 j2N1.Similarly, another wire pressure contact portion j3 also have the part j3L overlap in the horizontal with wire pressure contact portion j2 with And with a nonoverlapping part j3N of wire pressure contact portion j2.This relation is also formed when wire pressure contact portion j3, j4 is paid close attention to.Together Sample ground, when concern wire pressure contact portion j4, j5, wire pressure contact portion j5, j6, wire pressure contact portion j6, j7, wire pressure contact portion j7, j8, line This relation is also formed when shape pressure contact portion j8, j9, wire pressure contact portion j9, j10, wire pressure contact portion j10, j11.Therefore, originally showing In example, all wire pressure contact portion j, j ... can be formed in the moderate size scope in transverse direction.

However, being not limited to case above.That is, as long as described above, forming above-mentioned heavy at least two wire pressure contact portion j, j Folded relation, it becomes possible to correspondingly enjoy the work placed above-mentioned wire pressure contact portion j, j ... in moderate size scope in the horizontal Use effect.

It should be noted that herein as the wire pressure contact portion j2 in observation Figure 11 in detail, with side in the horizontal The adjacent nonoverlapping part j2N of wire pressure contact portion j1 are what the wire pressure contact portion j3 adjacent with opposite side in the horizontal was overlapped Part j2L1.This relation, i.e. nonoverlapping with predetermined wire pressure contact portion j (j1) is then formed to wire pressure contact portion j3-j11 Partly (j2N) is the part (j2L1) Chong Die with another wire pressure contact portion j (j3), thus across the overlap of each wire pressure contact portion Partly continuously configure all wire pressure contact portion j1j11 in the horizontal.

Therefore, all wire pressure contact portion j, the j ... for being formed at lower area AD are effectively placed within transverse direction less In moderate size scope wide or not too narrow, as a result, restrained effectively the deterioration of the outward appearance of band member 20a or when contact band Sticky feeling during component 20a.

Additionally, in the example of fig. 11, in order to form overlapping relation in the horizontal without problems, wire pressure contact portion j's The appropriate inclined angle alpha from fore-and-aft tilt in addition to 90 degrees is oriented, and also inclination that all wire pressure contact portion j, j ... are alignd The size of angle α and inclined orientation.Specifically, in this example, when from a thickness direction non-skin side observe lower region During the AD of domain, the size of inclined angle alpha is set to 30 degree, and inclined orientation is rotated counterclockwise from longitudinal direction.

However, case above is not limited to, as long as wire pressure contact portion j, j can be made to overlap each other in the horizontal.That is, incline The size of bevel angle α is not in any way limited to above-mentioned 30 degree, and it is possible to further not to all wire pressure contact portion j, The size of j ... alignment inclined angle alphas, and it is possible to further inclined orientation of not alignd to all wire pressure contact portion j, j ....

Additionally, in this example, wire pressure contact portion j, the j for overlapping each other in the horizontal are not configured as in the vertical each other not It is adjacent.For example, in the example of fig. 11, in the case where two wire pressure contact portions j1, j2 are paid close attention to, the two wire pressure contact portions J1, j2 overlap each other in the horizontal, but when observing in the vertical, have other wire pressure contact portion j5, j9 to be present in two Between wire pressure contact portion j1, j2, thus wire pressure contact portion j1, j2 for overlapping each other in the horizontal are non-conterminous in the vertical.Therefore, Wire pressure contact portion j1, the j2 for overlapping each other in the horizontal can be separated moderately in the vertical, as a result, can be effectively prevented from State the intensive configuration of wire pressure contact portion j1, j2 for overlapping each other.

In this example of Figure 11, this position relationship is formed to all wire pressure contact portion j, j ....In other words, in horizontal stroke Wire pressure contact portion j2, the j3 for overlapping each other upwards form this position relationship, and similarly to wire pressure contact portion j3, j4, line Shape pressure contact portion j4, j5, wire pressure contact portion j5, j6, wire pressure contact portion j6, j7, wire pressure contact portion j7, j8, wire pressure contact portion j8, J9, wire pressure contact portion j9, j10, wire pressure contact portion j10, j11 form this position relationship.Therefore, efficiently avoid in transverse direction On wire pressure contact portion j, j for overlapping each other intensive configuration in the vertical.

However, being not limited to case above.In other words, as long as two wire pressure contact portions j, j overlapping each other in the horizontal exist It is not adjacent to each other on longitudinal direction, it becomes possible to correspondingly to enjoy the action effect for avoiding above-mentioned configuration intensive in the vertical.

Additionally, in this example of Figure 11, the quantity of the wire pressure contact portion j for overlapping in the horizontal any position in the horizontal It is less than 2 to put place.The numerical value 2 is the minimum value of the quantity for overlapping.Exist therefore, it is possible to be effectively prevented from wire pressure contact portion j, j ... Intensive configuration in transverse direction.

Figure 12 is the schematic plan view of first variation with placing graphic pattern of wire pressure contact portion j, j ....First deformation The middle section ADc with placing graphic pattern suitable for the lower area AD of dorsal part band member 20b of example.In other words, such as above-mentioned Fig. 6 institutes Show, multiple wire pressure contact portion j, j ... are formed at the middle section in the lower area AD of dorsal part band member 20b with this with placing graphic pattern ADc.It can be clearly seen that all foregoing rule/rules should also be met with placing graphic pattern from Figure 12, thus omit specifically It is bright.By the way, in the example of fig. 6, the wire pressure of wire pressure contact portion j, j ... of veutro band member 20a and dorsal part band member 20b Socket part j, j ... is formed at the reciprocal region using center CL1 in the horizontal as border, and with this side Formula, can be such that the configuration of wire pressure contact portion j, j ... disperses in the horizontal.As a result, it is possible to suppress when the pants type urine in hookup 4 Sticky feeling during cloth 1.

In the above-described embodiment, as shown in figure 11, the quantity of wire pressure contact portion j, j for overlapping in the horizontal is not made in horizontal stroke Upward any position is equal number.For example, the in the horizontal first concern position P1 in fig. 11 and the second concern Position P2 has two wire pressure contact portion j, j, therefore the quantity of the wire pressure contact portion j for overlapping is set to " 2 ", but in Figure 11 In the 3rd concern position P3 or the 4th concern position P4 only have a wire pressure contact portion j, therefore the wire pressure contact portion j for overlapping Quantity is not set to " 2 ".Therefore, using, with placing graphic pattern, not making wire pressure contact portion j, j for overlapping in the horizontal in Figure 11 Quantity any position in the horizontal is equal number.

By contrast, in second variation of Figure 13, except wire pressure contact portion j1, j9 positioned at two ends in the horizontal In addition, the quantity of wire pressure contact portion j, j for overlapping in the horizontal any position in the horizontal is made to be equal number, specifically Ground, is set to " 2 " as the example quantity of the equal number.Therefore, it is possible to make wire pressure contact portion j, j ... in the horizontal Configuration distribution equalization, as a result, can suppress uncomfortable when contact is formed with the region of these wire pressure contact portions j, j ... Sense, or outward appearance can be made satisfactory.

In some cases, as shown in the schematic plan view in Figure 14, except the second variation in placing graphic pattern with Outward, imitated wire pressure contact portion jD1, jD9 is formed in the vertical at the position for not cutting off rubber thread 27 that can be.In showing for Figure 14 In example, each imitated wire pressure contact portion jD1, jD9 are respectively formed as and wire pressure contact portion j1, the j9 at the two ends in transverse direction Respective part j1N, j9N not overlapped or not in the horizontal.

Therefore, when imitated wire pressure contact portion jD1, jD9 is further contemplated, the wire pressure contact portion for overlapping in the horizontal can be made The quantity of j is that any position in the horizontal is equal number " 2 ".Therefore, it is possible to effectively further suppress when contact It is formed with the sticky feeling during region of these wire pressure contact portions j, j ....The quantity of the wire pressure contact portion j of overlap is not made necessarily It is " 2 " the multiple quantity beyond " 2 " that quantity can be made to be " 3 " or " 4 " etc..

Additionally, in any example shown in Figure 11 to Figure 14, there is no wire pressure contact portion j, j ... to overlap in the vertical, but It is that in this state, PC is positively cut at that the rubber thread 27,27 ... being arranged side-by-side in the vertical can be in the horizontal It is disconnected.However, being not limited to case above.In other words, as long as PC is cut off at each rubber thread 27,27 ... can be in the horizontal one, Wire pressure contact portion j, j ... can just be overlapped slightly from one another in the vertical.
