In addition, constituting the inner layer piece 41 and outer-skin sheet 42 in veutro waist portion 40 can be configured with what can be stretched in the horizontal Sheet element (such as flexible nonwoven fabrics).In this case, even if being not provided with veutro elastica 43, veutro waist portion 40 also can Retractility in the horizontal is enough shown by the elastic force (convergent force) of flexible nonwoven fabrics itself.
Dorsal part waist portion 30 includes the flat member at the back of covering wearer.The dorsal part waist portion 30 is by non-woven fabrics etc. The piece of rectangular shape is made and has in plan view, and the dorsal part waist portion 30 is configured to its length direction (long side Direction) along transverse direction.As shown in figure 3, dorsal part waist portion 30 is formed as follows:Make inner layer piece 31 and outer-skin sheet 32 from Skin side on thickness direction is overlapping, is then connect inner layer piece 31 and outer-skin sheet 32 using the bonding agent of hot-melt adhesive etc. It is combined together.Note, can be constructed as below:Interior load 31 and outer load 32 are monomer members (same components), and should Monomer members are folded and overlapping to form dorsal part waist portion 30.Dorsal part waist portion 30 is placed in the one end 10a of absorbent main body 10 And it is engaged and fixed to the one end 10a of absorbent main body 10.The part for being placed in absorbent main body 10 in dorsal part waist portion 30 It is arranged at the central portion in the horizontal in dorsal part waist portion 30.
Note, different from veutro waist portion 40, dorsal part waist portion 30 is not provided with breach.As described above, being worn for suppression Navel for the person of wearing etc. sets breach 45 with purpose that diaper 1 is contacted.It therefore, there is no need to set corresponding to breach 45 in dorsal part Breach.
It is substantially same with veutro waist portion 40, it is configured to (rise for convenience along multiple elastic components of transversal stretching See, referred to as dorsal part elastica 33) abreast it is configured at dorsal part waist portion 30 in the vertical (referring to Fig. 2).Extend in the horizontal Under state using bonding agent by dorsal part elastica 33 to be engaged and fixed to dorsal part waist portion 30.This is provided dorsal part waist portion 30 Retractility in the horizontal, and retractility is provided to the waist opening 1a of diaper 1.In addition, same with veutro waist portion 40 Sample, the retractility nonwoven that can be stretched in the horizontal can be configured with by constituting the inner layer piece 31 and outer-skin sheet 32 in dorsal part waist portion 30 Cloth etc..
<The configuration of bonding agent around breach 45>
As described above, the inner layer piece 41 and (and the veutro bullet of outer-skin sheet 42 in veutro waist portion 40 will be constituted using bonding agent Property line 43) it is engaged with each other.Usually, in the case where bonding agent is arranged at into sheet element, sheet element is provided with bonding agent Part becomes rigidly higher and hard than the part for being not provided with bonding agent.Therefore, in diaper 1, if bonding agent be arranged at including The outer rim of breach 45 edge 46 (that is, corresponding to breach 45 edge part), then the rigidity of edge 46 is uprised.This may Sense of touch deterioration around the navel enabled a wearer to.Especially, neonatal skin is slim and frahile, when diaper 1 is worn, edge 46 rigidity can exceedingly stimulate navel region, and can cause more discomforts.In this case, instead, formed originally The breach 45 of the contacts such as the navel to suppress sheet element and wearer can deteriorate sense of touch.
In consideration of it, in diaper 1 according to the embodiment of the present invention, by being formed at the breach in veutro waist portion 40 At least a portion region of 45 edge 46 is not provided with bonding agent, it is suppressed that when diaper 1 is worn, edge 46 is exceedingly stimulated The skin of wearer.Configuration of the bonding agent in diaper 1 is described below.
Fig. 6 A to Fig. 6 C are the schematic plans for showing the region for being provided with bonding agent in the veutro waist portion 40 of diaper 1 Figure and partial section.In Fig. 6 A to Fig. 6 C, represent to form the region of the edge 46 of breach 45 with oblique line portion, and with the moon Shadow represents to be provided with the region (following, also known as bonding region HMA) of bonding agent.Note, Fig. 6 A to Fig. 6 C show veutro waist The state that body portion 40 extends in the horizontal.
As shown in Figure 6A, the bonding region HMA of banding is formed at predetermined along what is extended laterally in veutro waist portion 40 Region.In addition, bonding region HMA is not formed at the lower zone of edge 46.Specifically, in fig. 6, outside breach 45 Rise in the region with width D 2 downwards and be not provided with bonding agent throughout entire length in the horizontal in the lower end of edge.Edge 46 The lower zone is the region of the highest possibility contacted when diaper 1 is worn with the navel with wearer, and is to work as The region of possibility with the skin being absorbed in around navel when the positive neonate for wearing diaper 1 is in forward lean.Therefore, because It is not provided with for bonding agent in the scope with preset width (width D 2) from the lower end of breach 45, so the rigidity of the part is low Rigidity in other parts (part for corresponding to the bonding region HMA with shadow representation), and can suppress to wearer's The stimulation in navel region.
As discussed above, it is desired to, the width D 2 of edge 46 is set at essentially 2mm.In other words, according to the present invention's In the diaper 1 of embodiment, coating adhesive in the way of at least 2mm gap is left by the lower end 45a from breach 45.Should It is noted that the width D 2 of edge 46 can be set as into below 2mm according to the size and type of diaper 1.
In fig. 6, a part of region in both lateral sides of edge 46 is overlapping with bonding region HMA.In other words, lacking There is the region for being provided with bonding agent in the both sides in the horizontal of mouth 45.Opened at least with the central strip in transverse direction in these regions The width W1 of breach 45 more than 1/2 distance (referring to Fig. 4), and when diaper 1 is worn, these regions and navel are direct The possibility of contact is low.For this reason, compared with there is high rigidity with the lower end 45a regions of edge 46, even if these areas Domain has high rigidity, stimulates the possibility in the navel region of wearer relatively low these region transitions.Therefore, bonding agent can It is arranged at the both sides in the horizontal of edge 46.
Use such as spiral coating (spiral application), Ω coatings, control beam coating (control beam The bonding agent for forming bonding region HMA is coated on inner layer piece 41 by the method for known coating adhesive application) etc. With the presumptive area of at least one of outer-skin sheet 42.Bonding agent need not be arranged at by the shade table in Fig. 6 A in an uniform manner The bonding region HMA shown overall region.In addition, working as coating adhesive to be joined together inner layer piece 41 and outer-skin sheet 42 When, in the state of veutro elastica 43 extends in the horizontal, veutro elastica 43 is clipped in and is engaged in inner layer piece 41 and outer layer (referring to sectional view of A-A interceptions along Fig. 6 A etc.) between piece 42.The convergent force of these veutro elasticas 43 assigns veutro waist The retractility of body portion 40 in the horizontal.Note, the configuration of veutro elastica 43 is not limited to the configuration shown in Fig. 6 A.For example, bonding Region HMA can include the part for not configuring veutro elastica 43, or veutro elastica 43 can be configured at bonding region HMA Part in addition.In addition, although bonding region HMA is arranged between veutro elastica 43 and outer-skin sheet 42 in figure 6, it is but viscous Meeting region HMA can be arranged between veutro elastica 43 and inner layer piece 41.
Compared with Fig. 6 A situation, Fig. 6 B show a case that bonding region HMA is set larger.In fig. 6b, glue Connect the center in the horizontal among the lower zone of edge 46 that agent is not provided with veutro waist portion 40 have it is predetermined The region of width, bonding agent is arranged at the region beyond above-mentioned zone.Specifically, bonding agent is not provided with the outer rim from breach 45 Lower end (in fig. 6b corresponding to the base of breach 45) rise downwards have width D 2 region.Therefore, it can suppress when urine While when cloth 1 is worn to (neonatal) umbilical region field stimulation of wearer, inner layer piece 41 and outer-skin sheet 42 are increased The area of bonding part, so that the overall bond strength in veutro waist portion 40 can be improved, the more durable urine thus, it is possible to be formed Cloth 1.
Fig. 6 C show that bonding agent is configured between the entirety of edge 46 of breach 45 and bonding region HMA in the absence of overlapping Situation.Compared with Fig. 6 B, bonding agent is not provided with the both lateral sides region in edge 46 (from two transverse ends of the outer rim of breach 45 Play the region to lateral outer side with width D 2), thus inhibit the overall rigidity raising in edge 46.In other words, breach 45 Outer rim (edge) portion is integrally formed into softness, and this can provide better sense of touch for the veutro of wearer.In addition, bonding agent is set The outside (that is, the region of the lateral outer side of edge 46) in the horizontal in the region for being not provided with bonding agent is placed in, abdomen is therefore ensured that Enough bond strengths in the entirety of side waist portion 40.
Note, Fig. 6 A to Fig. 6 C show that bonding agent is not provided with the lower zone in edge 46 (from the lower end of breach 45 There is the region of width D 2 downwards) example, as long as but bonding agent be not provided with least a portion of edge 46, just The rigidity raising of the part can be suppressed, this is produced as the effect that wearer provides improved sense of touch.
This is equally applicable to inner layer piece 41 and outer-skin sheet 42 and is made up of flexible nonwoven fabrics for can stretching in the horizontal etc. Situation.Fig. 7 be show to be provided with the case of being made up of the sheet element with retractility in the veutro waist portion 40 of diaper 1 it is viscous Connect the figure in the region of agent.Note, Fig. 7 shows corresponding to Fig. 6 C, entirety of edge 46 and the nonoverlapping feelings of bonding region HMA The example of condition.In the figure 7, because having used flexible nonwoven fabrics, veutro elastica 43, and the He of inner layer piece 41 are not provided with Outer-skin sheet 42 is directly engaged with each other via bonding region HMA.Also in this case, be formed with bonding region HMA region with Formation described in Fig. 6 A to Fig. 6 C has bonding region HMA region same.In other words, at least a portion of the edge 46 of breach 45 It is not provided with bonding agent, the lower zone (region downwards from the lower end of breach 45 with width D 2) of such as edge 46 is not provided with Bonding agent.Therefore, it is suppressed that the rigid raising of edge 46, this can provide improved sense of touch for the navel region of wearer.
In addition, veutro elastica 43 can be arranged at without being disposed on inner layer piece by forming bonding region HMA bonding agent 41 or outer-skin sheet 42.Fig. 8 is the figure for showing the bonding region in the case where bonding agent is arranged at elastica.As the A-A in Fig. 8 is cut Shown in face figure and section B-B figure, inner layer piece 41 and outer-skin sheet 42 connect via the bonding agent on the surface for being applied to veutro elastica 43 It is combined together.In other words, being configured with the region of veutro elastica 43 turns into bonding region HMA.
In fig. 8, along the veutro elastica 43 extended laterally, abreast interruption is configured in the vertical, thus bonding region HMA is shaped generally as striped design.In addition, veutro elastica 43 be each configured to it is overlapping not with the edge 46 of breach 45.Tool Body, veutro elastica 43 is configured at lower end region on the lower in the vertical than edge 46.In other words, under edge 46 Square region (region downwards from the lower end of breach 45 with width D 2) had both been not provided with veutro elastica 43 or had been not provided with bonding Agent.Therefore, the rigidity raising of the lower zone of edge 46, this can suppress the umbilical region to wearer when diaper 1 is worn The stimulation in domain.In addition, the configuration of veutro elastica 43 can adjust to be flexibly formed bonding region HMA.For bond strength With the elastic force for acting on veutro waist portion 40, this improves the free degree of design.Furthermore it is possible to which reducing the entirety of bonding agent makes Consumption, thus, it is possible to the rigid raising for suppressing to be caused by the bonding agent in the entirety of veutro waist portion 40.
In addition, veutro elastica 43 is arranged at the outside at the two ends in the horizontal of edge 46.In other words, away from veutro waist Longitudinal upper end 40b in body portion 40 is along in the veutro elastica 43 of landscape configuration, positioned at edge 46 in the range of height D1 Neighbouring lateral ends are configured at the lateral outer side of edge 46.That is, veutro elastica 43 and bonding agent are not provided with edge 46 The region (region to lateral outer side from two transverse ends of the outer rim of breach 45 with width D 2) of both lateral sides.Accordingly, it is capable to Enough suppress the overall rigid raising in edge 46, this can provide the better sense of touch when diaper 1 is worn.
Use the method for the known coating adhesive of seam coating (slit application) or spiral coating etc. Bonding agent is applied to veutro elastica 43.In addition, although bonding agent is set whole to veutro elastica 43 in the example of fig. 8 Body, but bonding agent can be discontinuously set along the length direction of veutro elastica 43.
<Another component is joined to the situation in veutro waist portion 40>
There is a situation where that another component is joined to the veutro waist portion 40 of diaper 1.Specifically, exist and utilize bonding agent engagement The situation of " another component " in addition to inner layer piece 41, outer-skin sheet 42 and veutro elastica 43.Illustrating below should be " another in engagement The configuration of bonding agent in the case of one component ".
Fig. 9 is to be used to engage split sheet element 50 in the case of showing that veutro waist portion 40 is provided with split sheet element 50 Bonding agent configuration figure.Split sheet element 50 in embodiments of the present invention is made up of film, non-woven fabrics etc., and is table Face is provided with the printed sheet of predetermined color or image.The split sheet element 50 is set to strengthen the design of diaper 1.In fig .9, Split sheet element 50 is configured to be clipped between inner layer piece 41 and outer-skin sheet 42, but split sheet element 50 can be relative to outer layer Piece 42 is arranged at non-skin side (that is, the most external in veutro waist portion 40), or can be arranged at skin relative to inner layer piece 41 Side.In other words, split sheet element 50 is the piece that non-skin side is arranged at relative to the absorbent main body 10 in veutro waist portion 40. Note, although veutro elastica 43 is eliminated into Figure 12 in following Fig. 9, but veutro elastica 43 can be set.
As shown in figure 9, being not provided with the lower zone in edge 46 (from breach for engaging the bonding agent of split sheet element 50 Play the region downwards with width D 2 in 45 lower end).Therefore, the rigidity in the region is less than the rigidity in other regions, and this can press down Make the stimulation to the navel region of wearer.Note, in fig .9, bonding agent is arranged at the non-skin side table of split sheet element 50 Face, to form bonding region HMA.Split sheet element 50 is engaged into outer-skin sheet 42 using the bonding region.In this case, Using the bonding agent for inner layer piece 41 and outer-skin sheet 42 to be joined together, split sheet element 50 skin side by split piece Component 50 is joined to inner layer piece 41.However, the configuration of the bonding agent of dorsal part and veutro can be in contrast.In addition, in fig .9, Bonding agent is arranged to the pattern corresponding with Fig. 6 C pattern, and the edge 46 of wherein bonding region HMA and breach 45 is not weighed each other It is folded, but can be similarly using reference picture 6 to the arbitrary graphic pattern illustrated by Fig. 8.Note, Fig. 9 illustrate only by for by abdomen The bonding region HMA for the bonding agent formation that side waist portion 40 and split sheet element 50 are joined together.Other bonding agents (for example, For joining inner piece 41 and the bonding agent of outer-skin sheet 42) configuration as being had been described above using Fig. 6 etc..
Figure 10 A and Figure 10 B are to show to be used for the bonding agent for engaging the piece 42f that turns back in the case where setting the piece 42f that turns back The figure of configuration.Strictly, the piece 42f that turns back is a part for outer-skin sheet 42, but the piece 42f that turns back herein will be as another structure Part is illustrated.In the case where piece 42f is turned back in setting, first, the length in the vertical of outer-skin sheet 42 is set to be longer than The length in the vertical of inner layer piece 41 so that when piece is overlapping in a thickness direction, longitudinal upper side end phase of outer-skin sheet 42 Protruded upward for longitudinal upper side end of inner layer piece 41.As shown in Figure 10 A, the extension of outer-skin sheet 42 is downward in the vertical (towards the skin side on thickness direction) turns back, and is turned back piece 42f with being formed, thus overlapping with inner layer piece 41 to be joined to inner layer piece 41.The edge part of the upper end of inner layer piece 41 turned back piece 42f covering (section B-B in reference picture 10A), thus inhibit when urine The edge part of inner layer piece 41 contacts the skin of wearer when cloth 1 is worn, and makes sense of touch more soft.
As shown in Figure 10 A, it will be turned back piece using the bonding agent for the end portion in the vertical for being arranged at the piece 42f that turns back 42f and inner layer piece 41 are joined together.Bonding agent (bonding region HMA) for engaging the piece 42f that turns back is not provided with edge 46 lower zone (region downwards from the lower end of breach 45 with width D 2).Therefore, the lower zone of edge 46 is firm Property will not be improved, and this can suppress the stimulation to the navel region of wearer.Note, bonding agent can be arranged at the horizontal stroke of edge 46 A part to the region of both sides and the region positioned at the portion outboard.The reason for its reason using Fig. 6 A with being illustrated is identical. In addition, although the bonding agent in Figure 10 A is arranged to the pattern corresponding with the pattern in above-mentioned Fig. 6 A, but can similarly answer With the arbitrary graphic pattern illustrated by reference picture 6 to Fig. 8.
In addition, in the case where piece 42f is turned back in setting, as shown in Figure 10 B, the position of the upper end of inner layer piece 41 can be set It is set to the lower end 45a less than breach 45.In this case, veutro waist portion 40 upper area (by away from veutro waist portion 40 upper end 40b in the vertical is the scope that height D1 is limited) in, less sheet element is overlapping in a thickness direction.This energy The pliability of upper area is enough improved, and the sense of touch when diaper 1 is worn can be improved.
In embodiments of the present invention, the length L42f in the vertical from the upper end for the piece 42f that turns back to lower end is set It is set to the length (D1+D2) in the vertical being longer than from the upper end of breach 45 to the lower end of edge 46.In addition, bonding region HMA It is formed at the position of the lower end less than edge 46.Assuming that L42f is shorter than D1+D2, then the region for being located at the lower section of edge 46 can not be utilized In bonding agent engagement turn back piece 42f bottom.In other words, it is formed with disengaged portion in the bottom for the piece 42f that turns back.At this In the case of kind, when putting on or taking off diaper 1, disengaged portion, which may roll or disturb, puts on/takes off action, and this may cause to ask Topic.By contrast, it is longer by the way that L42f is set to, prevent edge 46 bottom it is overlapping with adhesion area HMA while, Turn back piece 42f bottom can integrally be joined to inner layer piece 41.
In addition, in the case where piece 42f is turned back in setting, covering sheet element 60 can also be set.Covering sheet element 60 be Covering is turned back piece 42f end portion on thickness direction, direct with the skin of the lower edge for the piece 42f that prevents from turning back and wearer The component of contact.Figure 11 is the bonding agent for showing to be used to engage covering sheet element 60 in the case where setting covering sheet element 60 The figure of configuration.Same with above-mentioned example, the bonding agent (bonding region HMA) for engaging covering sheet element 60 is not provided with edge 46 lower zone (region downwards from the lower end of breach 45 with width D 2).This can be avoided the lower zone of edge 46 Rigid raising, and the stimulation to the navel region of wearer can be suppressed.
Note, in the case of the piece 42f that is not provided with turning back, covering sheet element 60 can also be set.In such case Under, covering sheet element 60 covers the upper part of absorbent main body 10 in a thickness direction, thus prevents absorbent main body 10 Upper end-face edge and the direct skin contact of wearer.
In addition, being joined to another component in veutro waist portion 40 also includes absorbent main body 10.Figure 12 is to show to be used for Engage the figure of the configuration of the bonding agent in absorbent main body 10 and veutro waist portion 40.As shown in figure 12, absorbent main body 10 The end of veutro on longitudinal direction is laminated with veutro waist portion 40, and is provided with the breach with the shape as breach 45.Cause This, a part for absorbent main body 10 is overlapping with the edge 46 of the breach 45 in veutro waist portion 40 in a thickness direction.In this hair In bright embodiment, as shown in figure 12, the bonding for engaging absorbent main body 10 and veutro waist portion 40 (inner layer piece 41) The lower zone that agent (bonding region HMA) is not provided with edge 46 (has downwards the area of width D 2 from the lower end of breach 45 Domain).This can suppress the raising of the rigidity in the region, and can suppress the stimulation to the navel region of wearer.Therefore, It can solve the problem that following problem:Suppress the new life to the main user of expection as diaper 1 according to the embodiment of the present invention The exceedingly stimulation in the navel region of youngster.In addition, although the bonding agent in Figure 12 is arranged to relative with the pattern in above-mentioned Fig. 6 A The pattern answered, but can be similarly using reference picture 6 to the arbitrary graphic pattern illustrated by Fig. 8.Note, Figure 12 illustrate only to be formed There is the bonding region HMA for the bonding agent for being joined together absorbent main body 10 and veutro waist portion 40.Other bonding agent (examples Such as, the inner layer piece 41 in engagement veutro waist portion 40 and the bonding agent of outer-skin sheet 42) configuration such as had been described above based on Fig. 6 that Sample.
In the case where more than two " other components " are joined to inner layer piece 41 or outer-skin sheet 42, in each " other components " It is each formed with bonding region HMA.For example, in the manufacturing process of diaper 1, being respectively coated for split sheet element 50 to be engaged The bonding agent of outer-skin sheet 42 and the bonding agent for absorbent main body 10 to be engaged to inner layer piece 41.In order to suppress breach 45 The rigid raising of edge 46, it may be desirable to which the bonding agent is not provided with edge 46.If because no bonding agent is set Edge 46 is placed in, then can correspondingly keep the pliability of edge 46, and this can suppress exceedingly to stimulate the tripe of wearer Umbilical zone domain.Even if however, only any one of the bonding agent is not arranged at into edge 46, also resulting in suppression to wearer's The effect of the stimulation in navel region.
