As shown in Fig. 2 and Fig. 3 B, for the main part 1s of incontinence pad 1, it is to prevent from urinating to the leakage of the end side of width direction Purpose, it is corresponding with each end of the width direction of absorbent core 11, it is equipped with a pair of of leakproof wall portion 40,40.A pair of of leakproof wall portion 40, 40 respectively the lateral plate 41,41 (being equivalent to sheet component) made of SMS non-woven fabrics for having carried out water-proofing treatment etc. etc. formed.Each side Piece 41,41 covers from skin side each end of the width direction of surface patch 21 and is arranged along its length.Moreover, with absorbability The corresponding position in each end of the width direction of core 11 is fixed on surface patch 21 by modes such as hot melts, is formed with cardinal extremity as a result, Portion 41b.In addition, the part 41f extended from base end part 41b to the substantial middle side of width direction is free end portion 41f, That is, part 41f essentially forms leakproof wall portion 40.On the other hand, extend from base end part 41b to the end side of width direction Part 41s reaches the ora terminalis of the width direction of incontinence pad 1, moreover, the part is Chong Die with surface patch 21 or back sheet 31, at the end It is engaged with surface patch 21 or back sheet 31 by modes such as hot melts on edge.

Here, for free end portion 41f, the elastomeric elements such as rubber covered wire alongst 45 are sharp under elongation state It is fixed with thermosol class bonding agent.Therefore, if 21 side of surface patch makes incontinence pad 1 along its length in a manner of as inner circumferential side Bending, then elastomeric element 45 shrinks and applies the convergent force, so, free end to free end portion 41f along its length Part 41f shrinks and is erected from surface patch 21 along its length, and thus free end portion 41f plays work(as leakproof wall portion 40 Energy.In addition, in the example of Fig. 3 B, free end portion 41f and base end part 41b are formed as two lateral plates being overlapped by folding 41, although moreover, inserted with elastomeric element 45 between two superimposed sheets of free end portion 41f, it is not limited to this.

In addition, base end part 41b is indicated with hatching in the approximate vertical view of Fig. 5, but in this example, for base end part The size of the width direction of 41b, the front end 41b1 and rear end 41b2 of length direction are set to width, on the other hand, before these Middle part 41b3 between end 41b1 and rear end 41b2 is set to narrow in a manner of the center side of width direction recess.And And increased as a result, in middle part 41b3 to the standing high-priority of leakproof wall portion 40, to seek the optimal of the ponding urinated Change, it is not limited to this.For example, the size of the width direction of base end part 41b can also be formed as throughout the complete of length direction Be formed as one fixed width longly.

In addition, as shown in Fig. 2, Fig. 3 A and Fig. 3 C, the front end 41fa in free end portion 41f and rear end 41fb In the state of being poured on base end part 41b, fixation is engaged with base end part 41b using thermosol class bonding agent etc., as a result, front end 41fa and rear end 41fb forms the non-rising portions not erected.Therefore, the convergent force of elastomeric element 45 mainly selectively by The middle section 41fm being applied between the front end 41fa being present in free end portion 41f and rear end 41fb, among this Part 41fm is formed as shrinking and be erected as leakproof wall portion 40.

It is that the explanation carried out, the incontinence pad of present embodiment 1 are constituted to the basic of the incontinence pad 1 of present embodiment above According to it is various improvement so that the anti-leakage for the discharge largely urinated relative to urgency incontinence etc. is improved, improved below for it into Row explanation.

First, the improvement of absorbent core 11 is illustrated.Fig. 6 A are in perspective representation incontinence pad 1 in addition to absorbent core 11 The approximate vertical view of structure in addition.In addition, Fig. 6 B and Fig. 6 C are B-B sectional views and C-C sectional views in Fig. 6 A respectively, it is each A figure all only shows absorbent core 11.

As described above, the plan view shape of absorbent core 11 is generally rectangular.But as shown in Fig. 6 A to Fig. 6 C, the absorption Property core 11 have on skin side to skin direction protruding portion 11P outstanding, moreover, protruding portion 11P spread absorbent core The complete cycle of the outer peripheral edge portion of 11 skin side it is formed continuously.Moreover, protruding portion 11P is existed with surrounding absorbent core 11 as a result, The mode of the central portion 11C of length direction is formed as annular.

Therefore, in the case where largely urine is by disposable be discharged for urgency incontinence etc., the protruding portion of annular can be passed through 11P effectively block can not the complete amount of 11 transient absorption of absorbability core urine.That is, urine can be temporarily stored in by protruding portion The space S P11 that 11P is surrounded.Moreover, thereby, it is possible to obtain the time of the soak time amount, to be inhaled until absorbent core 11 It prevents from urinating before having harvested urine and be leaked out from the main part 1s of incontinence pad 1, as a result, urine can be effectively prevented from length direction And width direction leaks out.

In addition, protruding portion 11P is formed along the outer peripheral edge portion of absorbent core 11, therefore the sky enclosed by protruding portion 11P Between SP11 continuous expand is formed respectively on the front side of the both sides of the middle position CLL of length direction and rear side.That is, the space SP11 in absorbent core 11 throughout since the front end of length direction until rear end position and continued presence.And And by making the uroflow after discharge cross space S P11, diffuse to the urine within the shorter time big on length direction In range.In addition, after the diffusion, the part for urinating the absorbent core 11 on the position flowed to by itself absorbs successively.Cause This, realizes to contributing to the area of the absorbent core 11 of the absorption of urine to be enlarged as a whole, as a result, can increase Uptake per unit time also can help to improve the anti-leakage relative to above-mentioned urgency incontinence in this way.

In addition, as shown in Figure 6A, the half portion of the half portion and rear side of the front side of length direction is made in the protruding portion 11P of annular Form mutual same shape.Therefore, when incontinence pad 1 is installed on underwear, even if having mistaken incontinence pad 1 in wearer Length direction front side and rear side and with script be mounted with incontinence pad 1 in the opposite direction in the case of, also can be according to upper The substantially symmetric shape for stating the protruding portion 11P of length direction makes the leak preventing effect of incontinence pad 1 not be damaged ground substantially, keep being expected Anti-leakage wear.I.e., additionally it is possible to be played by the incontinence pad 1 and prevent misdrawing effect.

In addition, protruding portion 11P be arranged in the width direction as each end of width direction it is parallel in the longitudinal direction The 1st straight section 11P1,11P1 (being equivalent to straight section) of a pair, and as each end of length direction, along length Direction is arranged with parallel in the direction of the width a pair the 2nd straight section 11P2,11P2.For example, each 1st straight section 11P1,11P1 are respectively provided with generally trapezoidal cross sectional shape, which maintains centainly, and along length side along its length To parallelly continuous, in addition, each 2nd straight section 11P2,11P2 are also respectively provided with generally trapezoidal cross sectional shape, the section Shape maintains centainly in the width direction, and parallelly continuous in the width direction.

Therefore, when incontinence pad 1 is installed on underwear by wearer, even if being installed in the longitudinal direction from appropriate location When the position of deviation, the urine in the direction of the width obtained by a pair the 1st straight section 11P1,11P1 can not be made substantially yet It blocks effect to change, even if expected anti-leakage can be played if when as a result, in the position deviateing.

In addition, as described above, the plan view shape of the 1st straight section 11P1 is parallel to the band-like of length direction, in addition, The plan view shape of 2nd straight section 11P2 is parallel to the band-like of width direction.That is, the 1st straight section 11P1 and the 2nd is straight There is band-like top surface 11P1t, 11P2t in each each comfortable skin side in linear parts 11P2, here, each top surface The width dimensions of 11P1t, 11P2t are set to such as 10mm or more.Moreover, if setting in this way, can reliably block The urine of protruding portion 11P is reached.

In addition, the projecting height L11P of protruding portion 11P as shown in Fig. 6 B and Fig. 6 C is preferably set in 0.5mm~5mm In the range of, it is more preferably set in the range of 1.5mm~3mm, in this instance, desired value is set as 2.0mm.And And if be set in such range, it can solve the problems, such as to generate less than 0.5mm, that is, temporary safe-keeping is inhaled The insufficient problem in the space of the urine before receipts, in addition, can solve the problems, such as to generate more than 5.0mm, that is, connecing The problem of sense of discomfort when having touched the skin of wearer.

Moreover, in the present embodiment, although with spreading the complete cycle of protruding portion 11P by the projecting height of protruding portion 11P L11P is set to be constant, it is not limited to this, can also make the projecting height L11P of protruding portion 11P different according to position. In addition, above-mentioned projecting height L11P refers to no load condition (the natural shape for not acting on protruding portion 11P in the external force of all State) under height, this is also identical as the above-mentioned width dimensions of protruding portion 11P.

In addition, depending on the situation, as shown in Figure 6B, the width of the top surface 11P2t of the 2nd straight section 11P2 can be made The width dimensions of top surface 11P1t of the size more than the 1st straight section 11P1 are spent, so, it is easy reliably to block The urine flowed along the length direction of incontinence pad 1.In this instance, the width dimensions quilt of the top surface 11P1t of the 1st straight section 11P1 It is set as 15mm, the width dimensions of the top surface 11P2t of the 2nd straight section 11P2 are set to 52mm.

The formation of absorbent core 11 with such protruding portion 11P is by corresponding in the skin side of absorbent core 11 On position and make the weight per unit area (g/m of the liquid-absorbent raw material as the constituent material of the core 11²) it is different and It realizes.That is, being set as in the plane of normal direction by thickness direction, with the weight per unit area of the position with protruding portion 11P The distribution pattern of the mode designing unit area weight of the weight per unit area of position more than no protruding portion 11P, according to this Distribution pattern and make liquid-absorbent raw material through-thickness be laminated and form the absorbent core 11.

Moreover, if being formed in this way, with the position enclosed by protruding portion 11P in the position without protruding portion 11P It compares, swelling quantity of the position with protruding portion 11P after absorbing urine is big.Therefore, even if after absorbing the urine, there is protruding portion The position of 11P is more prominent to skin side, and thereby, it is possible to the space S P11 that will be enclosed by protruding portion 11P to maintain into big state. Moreover, as a result, can also will be unable to that the complete urine of 11 transient absorption of absorbability core is no any to ask in discharge urine next time It is temporarily stored in space S P11 to topic.

Herein, it is preferable that the weight per unit area of the position with protruding portion 11P can be set as to do not have protruding portion 1.2~4.0 times of the weight per unit area of the position of 11P.And.If set in this wise, it can be effectively prevented from and ask as follows Topic.First, less than 1.2 times, it will produce and be difficult to ensure to be difficult to greatly by the projecting height L11P of protruding portion 11P The problem of playing sufficient anti-leakage has the position of protruding portion 11P and without prominent in addition, more than 4.0 times The problem of poor rigidity gone out between the position of portion 11P becomes larger and causes to be easy not feeling well when wearing incontinence pad 1, but if such as It is upper to be set as 1.2~4.0 times describedly, then it can avoid these problems.

In addition, mentioning specific numerical value, such as the weight per unit area of the position with protruding portion 11P is set as 550 ~850 (g/m²) range, the weight per unit area of the position without protruding portion 11P is set as 200~500 (g/m²) Range.

Next, being illustrated for the improvement of leakproof wall portion 4.As shown in figure 5, leakproof wall portion 40 starts from surface patch 21 The beginning set-up positions 41be of standing is the edge 41be of the center side of width direction in the base end part 41b of leakproof wall portion 40 This is started set-up positions 41be and is set as and absorbability as the improvement of leakproof wall portion 40 by position, but in the present embodiment The corresponding positions the 1st straight section 11P1 of the protruding portion 11P of core 11.Specifically, set-up positions 41be positioning will be started It is fixed at the position on the top surface 11P1t of the 1st straight section 11P1, while by the base end part 41b of leakproof wall portion 40 Surface patch 21.Then, so, then leakproof wall portion 40 can be made mutually to be cooperateed with the 1st straight section 11P1, as high Occlusion part and function, and thus improve width direction anti-leakage.

In addition, with reference to Fig. 2 of front, describes and " be located at the front end 41fa and rear end 41fb in free end portion 41f Between middle section 41fm erected by elastomeric element 45 " situation (Fig. 2), here, by above-mentioned middle section 41fm Length direction range as prescribed limit Rm in the case of, it is preferable that in prescribed limit Rm include absorbent core 11 Protruding portion 11P a pair the 2nd straight section 11P2,11P2 (being equivalent to " each end of the length direction in protruding portion ") At least part.

Moreover, so, by the convergent force of elastomeric element 45, each 2nd straight section 11P2,11P2 are respectively carried It rises to skin side, thereby, it is possible to so that the gap between the skin of wearer is become smaller.Therefore, the urine energy flowed along its length It is enough reliably to be blocked by each end of the length direction of each 2nd straight section 11P2,11P2.

Next, to only being illustrated partially with the improvement of adhesive portion 33.As shown in figure 4, it is to apply with adhesive portion 33 that should stop partially Spread on the thermosol class bonding agent of the prescribed limit of the non-skin side of back sheet 31.Moreover, in the example of fig. 4, in width The left and right in direction, a pair of band-like stopping separate regulation with adhesive portion 33,33 in a manner of the Central Line CLW for clipping width direction partially Interval and the position since the front end of back sheet 31 until rear end is formed continuously.

Here, in the present embodiment, in the case of incontinence pad 1 from thickness direction, respectively only partially with adhesive portion 33, 33 are configured to Chong Die with a part of the 1st straight section 11P1 of absorbent core 11.Specifically, such as the section in Fig. 4 Shown in line, respectively only partially with the part of the end side of the width direction in adhesive portion 33 be configured to respectively with hithermost 1st straight line The center side of width direction in the 11P1 of shape part partly overlaps.

Therefore, the part of the center side of the width direction at least in the 1st straight section 11P1 is constrained to relative to interior Clothing is substantially irremovable, and as a result, when wearer has put on underwear, for the underwear along between the thigh of wearer, the 1st is linear Part 11P1 and the leakproof wall portion 40 that is erected on the top surface 11Pt of the 1st straight section 11P1 are also therewith along wearer's Between thigh.Moreover, as big with wearer as a result, it is possible to be formed the 1st straight section 11P1 and leakproof wall portion 40 The state being substantially close between leg more efficiently prevents from urine and is leaked from length direction and width direction.

But only it is not limited in above-mentioned a pair of of belt pattern with the formation mode of adhesive portion 33 partially.For example, it is also possible to logical It crosses in a pair only partially with thermosol class bonding agent is also coated on the position between adhesive portion 33,33, will only use 33 shape of adhesive portion partially At a continuous region in the width direction.Alternatively, it is also possible to by only partially with the size of the width direction of adhesive portion 33 into Row is suitably set, and is formed only in a manner of all be overlapped with the 1st straight section 11P1 from thickness direction Adhesive portion 33 is used partially.Moreover, if formed in this wise, the 1st straight section 11P1 is restricted to more can not relative to underwear Mobile, thereby, it is possible to further increase above-mentioned function and effect.

Next, being illustrated to the improvement of the compression unit E of surface patch 21.With reference to Fig. 2 and as described above, in surface patch 21 Skin side on, be formed with the compression unit from both the skin side of thickness direction together compaction table dough sheet 21 and absorbent core 11 E.Moreover, in the present embodiment, the portion that the protruding portion 11P of absorbability core 11 is enclosed in the main part 1s of incontinence pad 1 On the central portion 1sCw for the width direction divided, as one kind of above-mentioned compression unit E, the 1st compression unit E1 is formed in along its length On straight line.For example, in the figure 2 example, the 1st compression unit E1 along its length the groove portion H1 with multiple (three) length, H1, H1, each groove portion H1 are formed with the state of the interval between groove portion H1 adjacent along its length.In addition, groove portion H1 It is respectively formed in a manner of the Central Line CLL for clipping the length direction of main part 1s of incontinence pad 1 than Central Line CLL by nearby The part of side and the part of rear side.

Moreover, if such 1st compression unit E1 is formed, as the thigh tightening force from the wearer for having put on underwear The main part 1s, such as Fig. 7 of incontinence pad 1 are applied to towards the both sides of the power F of the center side of width direction in the width direction like that Approximate stereogram shown in, using the 1st compression unit E1 as folding starting point, the main part 1s of incontinence pad 1 is in the big of width direction The mode that middle position is recessed to non-skin side is caused to be bent, thereby, it is possible to expand the space S P11 enclosed by protruding portion 11P (Fig. 6 A to Fig. 6 C).Moreover, as a result, more reliably can temporarily be stored to urine using space S P11.

Herein, it is preferable that as shown in the example of figure 2, length direction in the part enclosed by protruding portion 11P it is each On end, the 2nd compression unit E2, E2 arranges a pair of of formation in the width direction, moreover, each 2nd compression unit E2 be configured to from The center side of the center side of length direction towards end side and in the width direction is towards end side.In addition, in this instance, the 2nd pressure Contracting portion E2 by throughout endlong continuously at a continuous groove portion in the form of formed.

Moreover, if forming such 2nd compression unit E2, the feelings to main part 1s are acted in above-mentioned thigh tightening force F It under condition, is acted synergistically by the 2nd compression unit E2 and above-mentioned 1st compression unit E1, main part 1s is deformed into cup as shown in Figure 7 Shape.That is, the central portion 1sC on the length direction of main part 1s and two directions of width direction forms the shape being recessed to non-skin side Shape.Moreover, although above-mentioned central portion 1sC is detached between thigh as a result, part, the i.e. main part other than central portion 1sC Each end 1sLe, 1sLe of length direction in 1s and each end 1sWe, 1sWe of width direction are respectively formed with wearer's The state being close between lower abdomen, buttocks and thigh.That is, synergistically being marked off between main part 1s and thigh substantially closed Space.Therefore, urgency incontinence etc. can not the urine of the complete amount of 11 transient absorption of absorbability core be reliably temporarily stored in this Space.

Moreover, according to above-mentioned 1st compression unit E1 and the 2nd compression unit E2, main part 1s is easy to form cupuliform as shown in Figure 7 The reasons why it is as follows.

First, when the power F (Fig. 2) of the center side towards width direction between the thigh from wearer in the width direction Double side acting when being installed on the main part 1s of incontinence pad 1 of underwear, as shown in fig. 7, main part 1s is due to the 1st compression unit E1 In the central portion 1sC of width direction paddy shape is bent into a manner of being recessed to non-skin side.

On the other hand, in each section than central portion 1sC close to the end side of length direction, it is respectively arranged with a pair the 2nd Compression unit E2, E2, a pair the 2nd compression unit E2, E2 are generally V-shaped based on this, are compressed with towards the end side of length direction, the 2nd Portion E2, E2 are slowly opened at mutual interval.Therefore, in these each sections, paddy shape is bent because of caused by the 1st compression unit E1 Influence slowly mitigated with the end side towards length direction, as a result, than the 2nd compression unit E2, E2 of a pair close to length side To end side part, that is, end 1sLe, 1sLe formed along the plane as defined in length direction and width direction substantially plane Shape.Moreover, as a result, part, i.e. each end 1sLe of the length direction of main part 1s other than above-mentioned central portion 1sC, 1sLe and each end 1sWe, 1sWe of width direction are close between the lower abdomen of wearer, buttocks and thigh respectively, simultaneously Main part 1s is deformed into above-mentioned central portion 1sC from the shape detached between thigh.That is, main part 1s forms cupuliform.

In addition, in Fig. 2 and Fig. 7, although not being illustrated in detail in, the groove portion H1 and the 2nd compression unit of the 1st compression unit E1 The groove portion of E2 respectively has the mutually different deep of depth and superficial part.It is not limited to this.That is, the depth of groove portion can also be all over And it is endlong fixedly formed.In addition, depending on the situation, the 1st compression unit E1 and the 2nd compression unit E2 can also be formed as more The recessed portion of a island shape, in addition, the shape of the bottom surface of each recessed portion can also be round or rectangle.
