The preferred embodiment of following basis is with reference to description of drawings the present invention.Fig. 1 represents the axonometric chart of an embodiment of Breeches type disposable diaper of the present invention.Fig. 2 represents to assemble the exploded perspective view of the front state of diaper shown in Figure 1.Fig. 3 is the plane graph of deployed condition of the external cladding material of the disposable diaper in the presentation graphs 1.
The diaper 1 of the present embodiment possesses the absorber main body 10 that is in fact elongate shape and the external cladding material 11 that is configured in back-sheet 3 one sides of this absorber main body 10, and wherein said absorber main body 10 has the face sheet 2 of liquid permeability, the back-sheet 3 of water proofing property and the absorber 4 that is configured in the liquid retainability between two sheet materials 2,3.
The dual-side of external cladding material 11 is the hourglass shape of tightening up to the inside at the central part of length direction, draws the profile of diaper.External cladding material 11 is divided into the A of veutro section that is configured in the wearer veutro and is configured in the drosal part B of dorsal part and therebetween crotch C at its length direction.The A of veutro section and drosal part B are corresponding to end before and after the length direction of external cladding material 11, and crotch C is corresponding to the length direction central part of external cladding material 11.Dual-side A1, the A2 of the A of veutro section of external cladding material 11 and dual-side B1, the B2 of drosal part B are bonded with each other, and have formed waist peristome 5 and pair of leg peristome 6 at diaper 1.Engage by this, formed a pair of side seals S of section on the limit, the left and right sides of diaper 1.Described joint can example such as heat seal, high frequency sealing, ultrasonic sealing etc.
As shown in Figure 2, formed the sidepiece flanging 8,8 that the material by anti-liquid or water proofing property and aeration consists of in the left and right sides of the length direction of absorber main body 10.Near the free end of each sidepiece flanging 8, configuring sidepiece flanging elastic component 81 with elongation state.Accordingly, when dressing the diaper 1 according to Fig. 1 assembling, cause that because elastic component 81 shrinks sidepiece flanging 8 holds up, can prevent that liquid is to the outflow of the width of absorber main body 10.
In the end, front and back of external cladding material 11, along the front and back ora terminalis, configuring many waist elastic members 51,51 across its width.Each waist elastic members 51,51 is seized on both sides by the arms with elongation state by outer non-woven fabrics 12 and internal layer non-woven fabrics 13 and is fixed wtih.Each waist elastic members 51,51 dual-side B1, B2 at dual-side A1, the A2 of the A of veutro section of diaper 1 and drosal part B are bonded with each other in (bonding part), between two elastic components 51,51 the end or overlapping configuration, perhaps two elastic components 51,51 end are configured continuously until two bonding parts.Accordingly, as shown in Figure 1, near the waist peristome 5 of diaper 1, formed the waist rivel of continuous in fact ring-type.
The outer non-woven fabrics 12 that consists of external cladding material 11 is seized on both sides by the arms than outer non-woven fabrics 12 and internal layer non-woven fabrics 13 and is fixed each waist elastic members 51,51 position has the length of more extending, and the part that grows internal layer non-woven fabrics 13 of outer non-woven fabrics 12 is gone back to absorber main body 10 1 sides.Also can prolong the length of the fold back portion of outer non-woven fabrics 12, make it cover on the end, front and back of absorber main body 10 (being on the face sheet 2 on the end, front and back of absorber main body 10).
As shown in Figure 3, the bending section in the left and right sides of external cladding material 11 is configuring leg elastic member 61a, 61b.Each leg elastic member 61a, 61b configure along above-mentioned bending section.Each leg elastic member 61a, 61b are configured between outer non-woven fabrics 12 and the internal layer non-woven fabrics 13, and the engagement means with predetermined is fixed between two non-woven fabrics 12,13 with elongation state.Each leg elastic member 61a, 61b overlap at crotch C between the end separately.Simultaneously, the other end forms terminal in the position of each side of the A of veutro section and drosal part B.Each leg elastic member 61a, 61b, when the dual-side B 1 of dual-side A1, the A2 of the A of veutro section of diaper 1 and drosal part B, when B2 is bonded with each other, between the end of two elastic component 61a, 61b or overlapping configuration, perhaps the end of two elastic component 61a, 61b is configured continuously until two bonding parts.Accordingly, as shown in Figure 1, the leg opening section 6 of diaper 1,6 near formed the lower limb rivel of continuous in fact ring-type.
In the diaper 1 of the present embodiment, between separately the waist peristome 5 and leg opening section 6 of the A of flank section of diaper 1 and drosal part B, configuring the elastic component that a large amount of widths along diaper 1 extends.By the configuration elastic component, between waist peristome 5 and leg opening section 6, formed along the width of diaper 1 flexible a pair of the 1st zone (side stretching region) 71 and a pair of the 2nd zone 72 with the state that separates about separately.Configure the 1st elastic component 71a on the 1st zone 71, configured the 2nd elastic component 72a on the 2nd zone 72.The 1st zone 71 is between waist peristome 5 and leg opening section 6, and the 2nd zone 72 is between the 1st zone 71 and leg opening section.
The 1st elastic component 71a and the 2nd elastic component 72a are both seized on both sides by the arms with elongation state by outer non-woven fabrics 12 and internal layer non-woven fabrics 13 and are fixed wtih.The 1st elastic component 71a, when the B1 of the dual-side of dual-side A1, the A2 of the A of veutro section of diaper 1 and drosal part B, when B2 is bonded with each other, between the end of the 1st elastic component 71a of the A of veutro section and the 1st elastic component 71a of drosal part B or overlapping configuration, perhaps the end of each elastic component 71a, 71a is configured until two bonding parts.The 2nd elastic component 72a too.
The 1st elastic component 71a of the diaper 1 of the present embodiment is configured in the veutro section of diaper and the separately both sides of drosal part with elongation state on the one hand, simultaneously, is not configured in fact the veutro section of diaper and the width central part separately of drosal part.Specifically, the 1st elastic component 71a extends the limit, the left and right sides (being the limit, the left and right sides of outside clad material 11) be present in from diaper 1 until the about scope of the position of limit, the left and right sides extended line of absorbent core 41, but between a side extended line and another side extended line of absorbent core 41, the 1st elastic component 71a does not exist in fact.As a result, lay respectively at the veutro section of diaper and pair of right and left the 1st zone 71 of drosal part, to have formed respectively along the divided state of the width of diaper along the flexible rivel of the width of diaper, formed the side stretching region of the present embodiment.
In addition, the end 4a of the A of the veutro section side of the length direction of absorber 4, be positioned at the position than length direction centre line C L one side of center (center of the length direction of diaper 1) the more close diaper of C71 in the 1st zone (side stretching region) 71 of the A of veutro section, the end 4b of the drosal part B side of the length direction of absorber 4 is positioned at the position than length direction centre line C L one side of the more close diaper of center C71 in the 1st zone (side stretching region) 71 of back of the body abdominal part B similarly.
In the diaper 1 of the present embodiment, because between a pair of the 1st zone (side stretching region) 71, do not configure absorber 4, when diaper is dressed, the 1st zone 71 as each side stretching region is suitable for wearer well with more uniform pressure on the width of diaper, so can effectively prevent from falling under the dislocation of diaper.Moreover, because the pressure of the diaper of waist peristome when dressing is low, so also can prevent the aggravation fallen under the dislocation that the pressure by the waist peristome causes.Thereby the diaper outward appearance that can keep well the state of dressing also can be because not falling to hinder the action of wearer under the dislocation of diaper.
Even between a pair of the 1st zone (side stretching region) 71, put into the part of absorber 4, it is inner when not having the non-fibrous layer splenium of absorbent core 41 putting into part when this, above-mentioned effect also can produce.
When having put into the non-fibrous layer splenium of absorber 4 between the 1st zone 71, zone between one opposite side stretching region of diaper, be the rigidity of the part that does not just have absorbent core (the non-fibrous layer splenium of absorber) of absorber, be preferably 150～300cN, be particularly preferably 200～250cN.About the assay method of rigidity, in the embodiment of back, record and narrate.
In the diaper 1 of the present embodiment, because between the 1st zone (side stretching region) 71, do not put into the non-fibrous layer splenium of absorber 4 yet, so between the side stretching region, formed the soft area 73 that does not have absorbent core 41, the action of the wearer of the longitudinal extension that is accompanied by skin such as bend over to straighten one's back is being followed in this zone 73, heaves and restores to the direction of leaving skin.So, by so repeatedly variation, promote the circulation of the air between diaper and the wearer skin, be not easy to produce damp and hot and irritated dermatitis.In addition, by the heaving and restore of above-mentioned zone 73, can absorb the longitudinal extension of skin, can prevent from better under near the dislocation of the below waist peristome, falling with this.
Contrast with it, when absorbent core 41 enters between the 1st zone (side stretching region) 71 in large quantities, because the rigidity of absorber 4, the pressure of side stretching region easily becomes inhomogeneous at the width of diaper, have again, because can not absorb the longitudinal extension of skin, therefore be easy to produce under the dislocation again.
When not having absorber when the zone between an opposite side stretching region of diaper, can allow the better viewpoint of this effect set out, distance L a, the Lb (with reference to Fig. 3) between the center C71 of the position of both ends 4a, the 4b of the length direction of absorber 4 and the 1st zone (side stretching region) be preferably the 1st zone width W 1 1/2 or more than; In addition, distance L a ', the Lb ' (with reference to Fig. 3) between the center C71 of the position of both ends 41a, the 41b of the length direction of absorbent core 41 and the 1st zone (side stretching region) be preferably the 1st zone width W 1 1/2 or more than.
If the child uses diaper, distance L a, Lb or La ', Lb ' are preferably 5～20mm, more preferably 6～14mm.If adult diaper, distance L a, Lb or La ', Lb ' are preferably 10～40mm, more preferably 20～30mm.
In the diaper 1 of the present embodiment, no matter at the A of veutro section or at drosal part B, the position of end 4a, the 4b of the length direction of absorber 4 all is positioned at the position than more close length direction centre line C L one side in the 1st zone (side stretching region).In addition, among Fig. 3, the allocation position of absorber 4 dots, and the allocation position of absorbent core 41 represents with two dot dot dash.
In the disposable diaper 1 of the present embodiment, the 2nd elastic component 72a is also the same with the 1st elastic component 71a, be configured in the veutro section of diaper and the separately both sides of drosal part with elongation state on the one hand, simultaneously, be not configured in fact the veutro section of diaper and the width central part separately of drosal part.Specifically, the 2nd elastic component 72a extends the limit, the left and right sides (being the limit, the left and right sides of external cladding material 11) be present in from diaper 1 until approximately in the scope of the position of limit, the left and right sides extended line of absorbent core 41, but between a side extended line and another side extended line of absorbent core 41, the 2nd elastic component 72a does not exist in fact.As a result, lay respectively at the veutro section of diaper and pair of right and left the 2nd zone 72 of drosal part, to have formed respectively along the divided state of the width of diaper along the flexible rivel of the width of diaper.
As each elastic component in the diaper 1 of the present embodiment, the preferred use natural rubber, polyurethane series resin, polyurathamc is that resin, flexible nonwoven fabrics or heat fusing are the member that the retractility material such as telescoping member forms wire (collodion silk), banded (flat pattern adhesive tape), netted or film like respectively.
In the diaper 1 of the present embodiment, the pressure setting the during wearing of the diaper 1 in the 1st zone 71 is 1.1～2.5kPa.The 1st zone 71 is preferably formed in when dressing diaper 1 position that contacts with the position (the following ilium that also claims is regional) of (anterior superior illiac spine) from iliac crest (illiac crest) to anterior superior iliac spine of wearer.Iliac crest and anterior superior iliac spine are the anatomy terms.Iliac crest refers to that the position that represents with 9a among Fig. 4, anterior superior iliac spine refer to the position that represents with 9b in phase diagram.It is believed that all the time, in order to prevent that shorts type diaper from falling under the dislocation when dressing, particularly in order to prevent that the child is with falling under the dislocation of Breeches type disposable diaper in wearing, effectively improve the pressure of bringing together of the elastic component be provided in the waist peristome, utilize this waist peristome that shorts type diaper is close on the health of wearer (for example with reference to aforesaid patent documentation 2).But, present inventor's etc. result of study is found, in order effectively to prevent falling under the dislocation of shorts type diaper when dressing, press and compare with improving bringing together of waist peristome, bringing together of the diaper position corresponding with the ilium zone of wearer pressed be higher than that diaper was more effective in the past.Its reason is: because wearer child particularly, its physical trait is that waistline is outstanding, thus improve when pressing with bringing together of the contacted waist peristome of waistline that should be outstanding since bring together press high, the waist peristome dwindles gradually, and downslide is until the position that waistline attenuates thereby this waist peristome can misplace.
Fig. 5 represents baby's health is regarded as the state of circular cone.The angle that θ represents the line perpendicular with the tangent line of waist (some A), consists of with the horizontal line at body-facing center among the figure, F represents the elastomeric power of bringing together, P represents to result from the frictional force of F, and f1 represents to result to fall power under the dislocation of F, and f2 represents vertical resistance.Herein, f1=Fsin θ, P=ν N=ν f2=ν Fcos θ (ν represents coefficient of friction) is so fall the following formulate of power Z under the downward dislocation of some A.Z＝f1-P＝Fsinθ-νFcosθ＝F(sinθ-νcosθ)
Be appreciated that when waist from this formula to be in when producing the lower state that falls of dislocation, bring power (F) together larger, then lower to fall power just larger in dislocation.
As previously mentioned, the pressure the during wearing of the diaper 1 in the 1st zone 71 is 1.1～2.5kPa.If the pressure the during wearing of the diaper 1 in the 1st zone 71 is lower than 1.1kPa, then fixedly the 1st zone 71 of diaper 1 is with regard to difficult in the ilium of wearer zone, and its result falls under diaper 1 misplaces, the outward appearance of the diaper 1 under the wearing state non-constant that becomes.Particularly the crotch C of diaper 1 becomes obviously loose, also may become and urinate the just reason of seepage.On the other hand, when the pressure the during wearing of the diaper 1 in the 1st zone 71 surpasses 2.5kPa, the excessive health of banding wearer not only, and also difficult is understood in the operation of the wearing of diaper 1.From more effectively preventing from falling under diaper 1 dislocation, and the viewpoint of the wearing operability of the outward appearance of diaper 1 and diaper 1 is set out when more improving the wearing state, pressure during the wearing of the diaper 1 in the 1st zone 71 is preferably 1.1～2.0kPa, more preferably 1.2～1.8kPa.
Pressure during the wearing of the diaper 1 in the 1st zone 71, material or thickness, percentage elongation that can be by for example adjusting the 1st elastic component 71a or set the interval and control.
Pressure during the wearing of the diaper 1 in the 1st zone 71, diaper 1 can be worn on girth according to the M diaper is that to be worn on girth for 460mm, L number be to be worn on the cylinder that girth is 530mm for 500mm, Big number to dress, and utilizes to dress the contact of pressing determinator (strain) AMITECHNO to make and press determinator (AMI3037-2) to measure.The regulation of each size is decided according to the body weight of dressing the child, M number with 6～10kg, L number with 9～14kg, the Big number child take 12～26kg body weight as object.Usually, disposable diaper is representing the scope of child's body weight of setting as the diaper wearer in its packaging bag or description etc.The weight range of expression is during across above-mentioned two or more sizes, if being lower than the higher limit of 6kg or expression scope, the lower limit of expression scope surpasses 26kg (comprising the situation that does not represent higher limit), then can judge, be the scope of above-mentioned each size and the diaper that represents the overlapping size that becomes maximum of scope.For example, when the weight range of expression is 6～10kg, 7～10kg, can judge both M number, when the weight range of expression is 9～14kg, can judge it is L number, if the situations such as 12～22kg, 12kg or above (no maximum represents), 12～17kg, 12～20kg, 13～25kg can judge it is Big number.
Dress the concrete assay method of pressing as follows.
[assay method of the pressure in the 1st zone 71]
Use the air bag of Φ=15mm, and arrange according to the mode that air bag is centered close to the leading section (upper end) of waist peristome, measure to dress and press (P1).The center (Fig. 3 the position of E) of position between the position on the limit, the left and right sides of the limit, the left and right sides of diaper and absorbent core 41 or its extended line (draw from an end of the length direction of each side, and the extended line that extends in parallel of the length direction of diaper) of the diaper width of air bag is set.Then, the length direction along diaper 1 moves air bag center 5mm, mensuration wearing pressure (P2).Similarly, measure with the interval of 5mm, obtain P3, P4, P5 ... Pn.The mensuration of P1 to Pn on external cladding material 11, from the waist peristome until the scope that the left and right sides section of leg opening section is bonded with each other carry out.P1 is 2 places about veutro section, and every place measures twice, press as the wearing in the 1st zone (side stretching region) of veutro section take the meansigma methods that adds up to 4 measurement result.Dress and press P2～Pn to measure too.Also P1～Pn is added up to respectively 4 mensuration at drosal part, the wearing take its meansigma methods as drosal part is pressed.In the value of P1～Pn, the width take the distance between the position of satisfying continuously 1.1～2.5kPa as the 1st zone 71.For example, when P3～P6 satisfies above-mentioned value, the width in zone=(6-3) * 5=15mm.In addition, the center in the 1st zone 71 of this moment is the mid point of measuring point 3 and measuring point 6.
Setting drum circumference according to size is that the reason of 460mm, 500mm, 530mm is, child's the meansigma methods of waistline girth of main object of dressing the diaper 1 of the present embodiment is roughly 460mm, 500mm, 530mm.In addition, the waistline girth of herein saying, the variation of waistline girth when having considered child's posture change is the meansigma methods with the waistline of erect position and seat mensuration.If adult diaper, be that to replace girth be the cylinder of 460mm, 500mm, 530mm for the cylinder of 850mm with girth then.
To the position the anterior superior iliac spine certain width is arranged from the iliac crest of wearer, the 1st zone 71 diaper 1 in this width range is fixed on this position, can effectively prevent from falling under the dislocation of diaper 1.Consider from this viewpoint, in the diaper 1 of this enforcement state, the width in the 1st zone 71 length of the 1st zone 71 of the length direction of diaper 1 (namely along) W1 is set as 12～35mm.This width W is 20～35mm, particularly during 25～30mm, can more effectively prevent from falling under the dislocation of diaper 1 outward appearance of the diaper 1 in the time of can also more improving the wearing state and the wearing operability of diaper 1 (wearing easy etc.).
Under the wearing state of diaper 1, for make the 1st the zone 71 the contact wearers from the iliac crest to the anterior superior iliac spine between the position, the relation between the size of diaper 1 and the physique of wearer is very important.For example, when the main wearing object person's who considers shorts type diaper child, under the deployed condition of diaper 1, be set as 180～230mm apart from K1 (with reference to Fig. 3) between the length direction centre line C L of the center in the 1st zone 71 of the A of veutro section (center of the length direction of diaper 1) C71 and diaper 1, and under the deployed condition of diaper 1, be set as 180～230mm apart from K2 (with reference to Fig. 3) between the length direction centre line C L of the center in the 1st zone 71 of drosal part B (center of the length direction of diaper 1) C71 and diaper 1, can allow like this 1st zone 71 successfully contact the ilium zone of wearer.This numerical value be to the main wearing object person's of shorts type diaper child approximately 350 people implemented to determine behind the body measurement.Specifically as shown in Figure 6, if to put high front center at the veutro section left and right sides central point of the horizontal level height of anterior superior iliac spine as anterior superior iliac spine, put high rear center take drosal part as anterior superior iliac spine, so above-mentioned value is that to be that anterior superior iliac spine is put high front and back long with put the length setting of putting high rear center via crotch to anterior superior iliac spine in high front center from anterior superior iliac spine, this anterior superior iliac spine put high front and back long on, add the necessary length of considering diaper material thickness etc. and the numerical value that obtains is divided into two and obtains.This is set as 185～220mm apart from K1 and K2, when particularly being set as 195～215mm, then can makes the 1st zone 71 more successfully contact the ilium zone of wearer.
If adult diaper is set as 300～350mm to this apart from K1 and K2, when particularly being set as 305～335mm, then can make the 1st zone 71 more successfully contact the ilium zone of wearer.
The 1st zone 71 is present on the A of veutro section and the drosal part B, and the pressure during wearing on the A of veutro section and the drosal part B there is no need identical fully.If the pressure when being the wearing in the 1st zone 71 on the A of veutro section and the drosal part B satisfies 1.1～2.5kPa, then elastomeric material, thickness, percentage elongation, setting the interval also can be different on the A of veutro section and drosal part B.But, if the formation in the 1st zone 71 of the A of veutro section and drosal part B is excessively different, the position that then is bonded with each other between the left and right sides section of end before and after the length direction of external cladding material 11 might the front and back one party misplace when dressing, and unfavorable condition appears in the outward appearance of diaper 1.Therefore, the side that pressure is large during the wearing in the 1st zone 71 of the A of veutro section and drosal part B is as A, a little side during as B, (A-B)/ratio of A be preferably 30% or in.
Among the present invention, the length direction centre line C L of diaper 1 refers to, when in fact not dislocation and when being bonded with each other of dual-side B1, the B2 of dual-side A1, the A2 of the A of veutro section of diaper 1 and drosal part B, the straight line along the diaper width (with reference to Fig. 3) that passes through from the mid point of A1, the B1 of the deployed condition of diaper 1.Different therewith, for example shown in Fig. 7 (a) and Fig. 7 (b), when dual-side A1, the A2 of the A of veutro section do not engage with dual-side B1 ', the B2 ' of drosal part B, but when position B1, B2 place than the more close length direction of dual-side B1 ', B2 ' inboard engage, suppose from B1, B2 to B1 ', the zone of B2 ' is not for existing, then according to noted earlier such, determine the centrage of diaper length direction.
In addition, although the total length L of the external cladding material 11 of the deployed condition of diaper 1 can Set arbitrarily, consider that " the salubrious sense " when diaper is dressed and after using reaches " property fallen under the Anti-dislocation ", be preferably set to 460～520mm.Consider " sense of feeling at ease during wearing ", hope can cover umbilicus fully, considers from this viewpoint, is preferably set to 490～580mm again.
As previously mentioned, in the diaper 1 of the present embodiment, mainly be that the power of bringing together of the 1st elastic component 71a by being configured in the 1st zone 71 is fixed on diaper 1 on the body of wearer.In other words, different from shorts type diaper in the past, be configured in the power of bringing together of elastic component of waist peristome 5 in the diaper 1 of the present embodiment, not that diaper 1 is fixed on Main Means on the wearer's body.On the contrary, present inventor etc. confirm, if improve the power of bringing together of waist peristome 5, can encourage under the dislocation of diaper 1.From this viewpoint, in the diaper 1 of the present embodiment, the force value of the waist peristome 5 when diaper is dressed is set as the 0.3～1.5kPa that is lower than shorts type diaper in the past.The pressure mean values in the 1st zone 71 when this pressure is preferably dressed than diaper is hanged down 0.5～1.0kPa.In addition, the pressure setting of the waist peristome 5 when diaper is dressed can also be conducive to easily expand waist peristome 5 when diaper 1 is dressed in above-mentioned scope, easily dresses operation.In addition, if the pressure of waist peristome 5 is lower than 0.3kPa, the natural length of the diaper 1 before then dressing can increase, the unfavorable condition such as not attractive in appearance in the time of may occurring seeing as clothes.
The pressure of the waist peristome 5 when diaper is dressed if more preferably be set as 0.4～1.2kPa, when further being preferably set to 0.4～1.0kPa, then can more effectively prevent from falling under the dislocation of diaper 1.The pressure of waist peristome 5 can use the method identical with the assay method of the pressure in aforementioned the 1st zone 71 to measure.Namely inserting (wearing) girth in the waist peristome 5 of diaper 1 is the cylinder of 460mm (during the M diaper), 500mm (during the L diaper) or 530mm (during the Big diaper), leading section at distance waist peristome is dressed the air bag center of pressing determinator along the location, position of diaper length direction 15mm, measures to dress and presses.Mensuration divides carry out along circumferencial direction at 10 with the 50mm interval, with the pressure of its meansigma methods as the waist peristome.Shown in Fig. 7 (a) and Fig. 7 (b), when the position of the ora terminalis of the position of the ora terminalis of the waist peristome of veutro and the waist peristome of dorsal part is inconsistent, in the zone that coincides with veutro and dorsal part, the position of close end is as the waist peristome.The pressure of waist peristome 5 can be by for example adjusting waist elastic members 51 material, thickness, percentage elongation or set the interval and control.
In the diaper 1, preferably configuring elastic component 61a, 61b along leg opening section with elongation state in fact.And the pressure of the leg opening section 6 when diaper is dressed is preferably 1.0～2.4kPa, is particularly preferably 1.2～2.2kPa.Because the pressure of the leg opening section 6 when diaper is dressed is in above-mentioned scope, thereby the opening of leg opening section 6 can suitably be fitted in the pars inguinalis of wearer, can effectively prevent the lower limb fluid seepage on every side from wearer.In addition, even increase owing to the defecation of urinating makes the crotch weight of diaper 1 during use, can prevent that also the absorber of crotch is separated from the health of wearer, the outward appearance of the diaper 1 in preventing from dressing descends and urinates just seepage.Its result can obtain the diaper 1 of dressing state is remained on the effect of kilter etc.
The wearing of leg opening section is pressed in the following method and is measured.Device is identical with the mensuration of waist peristome with air bag.Inserting (wearings) girth in the leg opening section 6 of diaper 1 is the cylinder of 300mm, is configuring elastic component 61a, and the position of 61b is carried out 6 mensuration along circumferencial direction with the interval of 50mm.Elastic component 61a when 61b has many, measures at the width central point in the zone of this elastomeric member configuration.Wearing take 12 meansigma methods of right lower limb and left lower limb as leg opening section 6 is pressed.For not having fully or part does not have the diaper of leg elastic member 61a, 61b, with the configuration of corresponding position the wearing in zone of sidepiece flanging elastic component 81 press as the wearing of leg opening section and press.The reason that drum circumference is set as 300mm is that the meansigma methods of the length of the child's of the main object of the diaper 1 of wearing the present embodiment pars inguinalis (lower limb root) approximately is 300mm.
And then, in the diaper 1 of the present embodiment, zone beyond the 1st zone 71 when diaper is dressed, waist peristome 5 and the leg opening section 6, for example the pressure in the 2nd zone 72 between the 1st zone 71 and leg opening section 6 is preferably 0.2～0.8kPa, more preferably 0.3～0.6kPa.Thus, diaper 1 is close on the health of wearer, can effectively prevents fluid seepage.The 2nd zone 72 contacts the underside area (hypogastric region) in the ilium zone of wearer when dressing diaper 1.The width in the 2nd zone 72 length of the 2nd zone 72 of the length direction of diaper 1 (namely along) W2 is preferably 40～70mm, is particularly preferably 45～65mm.
Be associated therewith, with regard to diaper 1, when the pressure in the waist peristome 5 when diaper is dressed, the 71 and the 2nd zone 72, the 1st zone compared, the pressure in preferred the 1st zone 71 was the highest, secondly is that the pressure of waist peristome 5 is high, and the pressure in the 2nd zone 72 is minimum.By the pressure with each position such sequence is set, falls under the dislocation of the diaper 1 in not only can effectively preventing from dressing, diaper 1 also can cosily be close on the body of wearer, effectively prevents fluid seepage.
Disposable diaper of the present invention and the disposable diaper comparison of between an opposite side stretching region, having put in large quantities absorber, the tendency that has the length of the length direction of absorber to shorten, but as previously mentioned, occur to fall under the dislocation because be not easy, the absorbability of absorber has obtained effective performance, so can access the absorbent properties equal with above-mentioned disposable diaper.
From keeping and improve the viewpoint of absorbent properties, absorber 4 of the present invention is preferably such shown in Fig. 8 (a)～Fig. 8 (d), at the central part of crotch C, particularly in the position of diaper length direction centre line C L, absorbent core 41 is separated into middle body 41C by space 43 or slit and is positioned at the sidepiece part 41S of the both sides of this middle body 41C.In Fig. 8 (a)～Fig. 8 (d), symbol 42 is to cover skin contact one side of absorbent core 41 and the tissue paper (lining paper) of non-skin contact one side, each absorber 4 shown in Fig. 8 (a)～Fig. 8 (d), expression be the state of having removed after the part that skin contact one side to absorbent core 41 covers.Absorber 4 only preferably includes the part that is made of the tissue paper (lining paper) that covers absorbent core 41 interior, is not present in the position than more close waist peristome one side of middle position of side stretching region (the 1st zone).In other words, consist of end 4a, the 4b of absorber 4 and the sheet material between the waist peristome and preferably only have non-woven fabrics.That the non-woven fabrics of herein saying comprises is monolayer, multilamellar, non-woven fabrics and not the fleece of non-woven fabrics partly engage material that forms etc.
By being separated into middle body 41C and sidepiece part 41S, thereby when dressing diaper, about sidepiece part 41S hold up skin one side at wearer, form betwixt bag-shaped recess, therefore when preventing seepage, effectively brought into play the absorbability of absorber 4, so even the length of the length direction of absorber shortens, also can obtain sufficient leakageresistance.The middle body 41C of absorber 4 preferably has multi-ply construction.For example, Fig. 8 (d) is arranged to the middle body 41C of the absorber of Fig. 8 (a) to be obtained by 2 layers of structure that upper strata 41c and the 41d of lower floor consist of.The middle body 41C of the absorber 4 of Fig. 8 (b) and Fig. 8 (c) can be arranged to 2 layers of multiple structures such as structure too.
The preferred embodiment of above basis describes the present invention, but the present invention is not subjected to the restriction of above-mentioned embodiment.For example, in the diaper 1 of above-mentioned embodiment, between the A of veutro section and drosal part B waist peristome and leg opening section separately of diaper, has the 1st zone 71 as the side stretching region, and absorber end 4a, 4b among the A of veutro section and the drosal part B do not enter the position than more close waist peristome one side in the center in the 1st zone 71, but also can be only in a wherein square one-tenth the 1st zone 71 of the A of veutro section and drosal part B, and not configure the form of absorber at the position than more close waist peristome one side in the center in the 1st zone 71.But, preferably at least in the A of veutro section side, formed pair of right and left side stretching region, and do not configured absorber at the position than more close waist peristome one side in the center of this side stretching region.
In addition, as shown in Figure 9, between waist peristome 51 and the 1st zone 71, the 3rd zone 73 can be set also.Also have, in above-mentioned disposable diaper 1, that dual-side A1, the A2 of the A of veutro section and dual-side B1, the B2 of drosal part B are bonded with each other and have formed edge seal, but also can replace, utilize the various setting fastening members such as hook, clothing are buckled, magic tape (loop fastener) to make the shape of its in advance setting fastening formation pants type.Also have, the position that the joint of dual-side A1, the A2 of the A of veutro section and dual-side B1, the B2 of drosal part B or setting fastening position are not limited to the positive side of health also can be the forward a little or rearward position of health.
Furtherly, in above-mentioned disposable diaper 1, external cladding material 11 is made of skin and internal layer non-woven fabrics 12,13, but the material of external cladding material is not limited to this, also can be the laminated sheet of non-woven fabrics and water proofing property sheet material for example.In above-mentioned disposable diaper 1, draw the external cladding material 11 of diaper profile and the absorber main body 10 that is placed on it and consisted of diaper 1, but also can replace, be drawn the profile of diaper by face sheet and back-sheet, between two sheet materials, configure absorbent core.Also have, the position from the left and right sides section of the absorbent core of diaper veutro section and drosal part stretches out laterally also can be made of the elastic decorative strip material.

Comparative example
Use the roughly whole absorber that contains the fibrous layer splenium of absorbent core of length direction, the structure of this absorber is set to: either party of veutro section and drosal part, the fibrous layer splenium all enters into apart from waist peristome one side about the center 10mm of side stretching region, in addition, make the diaper identical with embodiment 1.
Estimate
Each diaper about embodiment and comparative example, by following method rigidity and the thickness in the zone between one opposite side stretching region are measured, the result is: embodiment 1 is 20.0cN, 0.68mm, and embodiment 2 is 212.7cN, 1.72mm, and comparative example is 378.4cN, 4.66mm.
The assay method of rigidity
The mensuration of rigidity is carried out according to ring type crush method (JIS P 8126).Test film is according at the 20mm centered by the center C71 of the 1st zone (side stretching region) on the diaper length direction, cut out as test film in the zone of the 150mm centered by diaper width center on the width.During the acquisition test sheet, facing up, be elongated under the state that the impact of telescoping member disappears in broad ways and carry out.The dual-side 10mm of the diaper width of the test film that collects altogether, the right-side-out side forms ring-type, is placed on the central authorities of the increased pressure board of testing machine.Until test film damaged by pressure, apply loading, the maximum loading when record disintegrates according to the predetermined speed of per minute 10mm.Each is measured 5 times, with its meansigma methods as rigidity.
The assay method of thickness
Thickness measurement is to use contactless thickness measurement meter (laser (LK-080) that (strain) KEYENCE makes) to measure.The diaper of deployed condition is extended along width, until the impact of telescoping member disappears, place plate (50mm * 50mm, 62.3g) at measuring point, measure at the core of this plate.Measuring point is that center C71, the width of the 1st zone (side constriction zone) is diaper width center at the diaper length direction.Each is measured 5 times, with its meansigma methods as thickness.
The inhomogeneity evaluation that the wearing of diaper width is pressed
Each diaper is taked the method identical with the assay method of the pressure in above-mentioned the 1st zone, the diaper of embodiment 1 and comparative example (being M number) is worn on the cylinder that girth is 460mm, the diaper of embodiment 2 (L number) is worn on the cylinder that girth is 500mm, under this state, for an opposite side stretching region of diaper veutro section one side, whether the pressure of the wearing on the diaper width is evenly estimated.The distance lateral location from the diaper side to absorbent core of any one diaper, the diaper width all is 60～70mm.For each diaper, take position that the center direction from its side (edge seal) to the diaper width (leaving the direction of edge seal) is left 10mm as starting point, air bag be centrally located on this position after measure to dress and press.Then the center direction along the diaper width moves the position of inserting air bag take 10mm as unit, dresses in each position finding and presses.Table 1 has shown measurement result.
Table 1
Can clearly find out from the result of table 1 demonstration, among each embodiment, the wearing of the side stretching region of diaper is pressed on the diaper width more even.One opposite side stretching region is because possess more uniform pressure and can be fit to wearer at the width of diaper respectively, thereby can effectively prevent from falling under the dislocation.
In addition, the rigidity in the zone between an opposite side stretching region is lower, and the zone between the side stretching region is along with the longitudinal extension of skin, the part of diaper or heave or restore, repeatedly change, so promoted the air circulation of diaper inside, be not easy to produce vexed wet and irritated dermatitis.
The diaper of corresponding comparative example near absorbent core, is dressed to press significantly and is reduced with it, and the viewpoint of falling from preventing from misplacing is down seen and is not preferred.In addition, the rigidity in the zone between an opposite side stretching region is high, and the zone between the side stretching region is not easy to be out of shape along with the longitudinal extension of skin, so can not promote the air circulation of diaper inside.
Breeches type disposable diaper of the present invention is not easy to occur in diaper is dressed to fall under the dislocation of the diaper that caused by the action of wearer etc.Namely because an opposite side stretching region possesses more uniform pressure and can be fit to well wearer at the width of diaper respectively, effectively prevented from falling under the dislocation.Moreover, because the pressure of the diaper of waist peristome when dressing is low, so also can prevent the aggravation fallen under the dislocation that the pressure by the waist peristome causes.Thereby the diaper outward appearance that can keep well the state of dressing also can be because not falling to hinder the action of wearer under the dislocation of diaper.In addition, can prevent that the elastic component that configures in the diaper from excessively tightening the health of wearer, dress comfort and become good.In addition, by falling under the dislocation that suppresses diaper, urinate just seepage in can suppressing to dress.
Have again, if do not configure the structure of absorber at the position than more close waist peristome one side in the center of side stretching region, longitudinal extension along with skin, the part of diaper or heave or reduce, repeatedly change, thereby promoted the air circulation of diaper inside, be difficult for producing vexed wet and irritated dermatitis.In addition, fall under the dislocation also more to be not easy to occur.
