Upper layer absorber 140a and lower layer absorber 140b preferably comprise macromolecule suction from the viewpoint of absorbent properties Acceptor and paper pulp fiber.At this point, the weight per unit area of polymeric absorbent body is opposite by polymeric absorbent body and paper pulp fiber The ratio of weight per unit area (weight per unit area of absorber in the present embodiment) together is added up to, i.e. macromolecule is inhaled The containing ratio of acceptor is preferably big in lower layer absorber 140b in upper layer absorber 140a ratio.In other words, the unit plane of paper pulp fiber The product weight opposite ratio that polymeric absorbent body and paper pulp fiber are added up to weight per unit area together, i.e. paper pulp fiber Containing ratio is preferably big in upper layer absorber 140a in lower layer's absorber 140b ratio.In this urine absorbent pad 100, due to paper pulp fiber Ratio in lower layer's absorber 140b ratio in upper layer absorber 140a high, thus it is possible to by urine further to lower layer's absorber The inside of 140b guides.Thereby, it is possible to use absorber 140 with being more nearly the capacity limitation of absorber 140.Polymeric absorbent The weight per unit area of body by the use level (quality) of polymeric absorbent body joined together by the absorber by required area divided by The required area calculates.The weight per unit area of paper pulp fiber is inhaled by subtracting macromolecule from the weight per unit area of absorber The weight per unit area of acceptor calculates.
Substantial middle with the length direction L in portion 112 between length direction L long and hip when upper layer absorber 140a is overlooked The shape of the substantially Pear-Shaped shunk.With in length direction L long and short big of width direction W when lower layer absorber 140b is overlooked Cause rectangular shape.Wherein, in lower layer absorber 140b, length direction L of the size than upper layer absorber 140a of length direction L Size is short, and the size of width direction W is shorter than the size of the width direction W of upper layer absorber 140a.Therefore, upper layer absorber 140a Two ora terminalis of length direction L of two ora terminalis compared to lower layer's absorber 140b of length direction L be located at the outside of length direction L, To longerly absorber 140a in upper layer is formed compared to lower layer's absorber 140b in the two sides of length direction L.In addition, upper layer absorbs Two ora terminalis of width direction W of two ora terminalis of the width direction W of body 140a compared to lower layer's absorber 140b are located at length direction L's Outside, so that upper layer absorber 140a is formed compared to lower layer's absorber 140b in the two sides of width direction W widerly.On in addition, When synusia 140c is overlooked for length direction L long the short rectangular shape of the size of width direction W.Wherein, upper synusia 140c Length direction L size it is identical as the size of length direction L of upper layer absorber 140a, the size of width direction W compares upper layer The size in portion 112 is long and shorter than the size of veutro portion 111 and drosal part 113 between the hip of the width direction W of absorber 140a, is in Rectangular shape.It should be noted that the shape for the vertical view of absorber 140 respectively constituted is any.
As shown in figure 3 and 4, in lower layer absorber 140b, absorbent core 144 has non-skin side The two sides of width direction W between 144sc, skin side 144sa and non-skin side 144sc and skin side 144sa 144sb,144sb.In addition, emulsion sheet 145 (core coating member) is included when being packed in absorbent core 144 and non-skin side 144sc Opposite non-skin side section 145sc；Opposite two side portions 145sb, 145sb with two sides 144sb, 144sb；And make For the part opposite with skin side 144sa and two skin side sections of both ends 145e1,145e2 including width direction W 145sa1,145sa2.Also, emulsion sheet 145 passes through the non-skin side by non-skin side section 145sc covering absorbent core 144 Face 144sc is covered two sides 144sb, 144sb of the width direction W of absorbent core 144 by two side portions 145sb, 145sb, with And cover the skin side 144sa of absorbent core 144 with being overlapped two skin side sections 145sa1,145sa2, to will absorb Property core 144 is packed in.
In absorber 140, the face of the skin surface side in the face and upper layer absorber 140a of the non-skin side of upper synusia 140c Mutually utilize the engagement (not shown) of the bonding agent of predetermined pattern.In addition, the non-skin side section 145sc of emulsion sheet 145 and absorption Property core 144 non-skin side 144sc mutually utilize the bonding agent of predetermined pattern it is (not shown) engagement.The unit area of bonding agent Weight (g/m2) it is contemplated that material, the performance etc. of urine absorbent pad 100 carry out appropriate adjustment.Weight per unit area is usually 0.5~50g/ m2, preferably 1~20g/m2。
On the other hand, the skin side 144sa of absorbent core 144 is not engaged with emulsion sheet 145.That is, absorbent core 144 Skin side section 145sa1,145sa2 of skin side 144sa (preferably two sides 144sb, 144sb) and emulsion sheet 145 (preferably two side portions 145sb, 145sb) do not engage, from without utilizing the engagement such as bonding agent, in turn, emulsion sheet 145 Both ends 145e1,145e2 of skin side section 145sa1,145sa2 are not engaged each other, to not utilize the engagement such as bonding agent.
The effect of skin side 144sa and the asynthetic occasion of emulsion sheet 145 to absorbent core 144 are illustrated.Fig. 5 It is the figure schematically illustrated to the effect of absorber 140.As shown in Fig. 5 (a), in urine absorbent pad 100 before use, inhaling The size T1 of size W1 of the property the received core 144 for example with width direction W, thickness direction T.Later, as urine absorbent pad 100 is made With the uptake of the urine in absorbent core 144 increases, 144 swelling of absorbent core therewith, in width direction W and thickness side Size increased on T.If the skin side section for the emulsion sheet 145 being located on the skin side 144sa of absorbent core 144 145sa1,145sa2 are bound on absorbent core 144 using bonding agent etc., then for the region of the inside of emulsion sheet 145 Volume forms the upper limit.At this point, the absorption of urine will receive limitation if absorbent core 144 becomes larger more than its volume.
But in the present embodiment, the skin of the emulsion sheet 145 on the skin side 144sa of absorbent core 144 Side section 145sa1,145sa2, two side portions 145sb, 145sb do not utilize bonding agent etc. to be bound on absorbent core 144. Thus, skin side section 145sa1,145sa2 of emulsion sheet 145, two side portions 145sb, 145sb can be easy in width direction W, thickness direction T is mobile and deforms, and can increase the volume in the region of the inside of emulsion sheet 145.Therefore, even if lower layer's absorber The absorption quantitative change of urine in 140b is more, 144 swelling of absorbent core of lower layer absorber 140b and in width direction W, thickness side Expanded to T, be corresponding to it, follow ground, skin side section 145sa1,145sa2 of emulsion sheet 145, two side portions 145sb, 145sb also can and deformation mobile in width direction W, thickness direction T.That is, being able to suppress emulsion sheet 145 interferes absorbent core 144 Swelling situation.As a result, lower layer absorber 140b is not limited by the uptake of urine, it can be close to absorber 140 Use absorber 140 to capacity limitation.For example, absorbent core 144 is configured to as shown in Fig. 5 (b), width direction W Size become big W2 more abundant than W1, the size of thickness direction T becomes big T2 more abundant than T1.
Wherein, at this point, the uptake with urine increases, the absorbent core 144 of lower layer absorber 140b starts swelling, such as Shown in Fig. 5 (b) like that, a part that the skin side 144sa of absorbent core 144 can always occur is uncovered the covering of piece 145 Occasion.In this way, at first sight, also will be considered that the absorbent core 144 of uncovered 145 covering loses shape.But in this reality It applies in mode, due to the skin side positioning upper layer absorber 140a in absorbent core 144, so, by by upper layer absorber The skin side 144sa for the absorbent core 144 that 140a covers uncovered 145 is covered, so as to prevent absorber 140 The state of affairs lost shape.In the occasion, emulsion sheet 145 and upper layer absorber 140a can also be bonded into less obstruction emulsion sheet 145 Movable degree.
In the present embodiment, in turn, emulsion sheet 145 is not engaged with upper layer absorber 140a.That is, the flesh of emulsion sheet 145 Skin side section 145sa, 145sa is not engaged with the face of the non-skin side of upper layer absorber 140a, from without utilizing bonding agent etc. Engagement.Therefore, emulsion sheet 145 will not be limited its movement and deformation by upper layer absorber 140a substantially.Even if lower layer absorbs as a result, 144 swelling of absorbent core of body 140b and to the outside of width direction W expand, the skin side section 145sa of emulsion sheet 145, 145sa will not be interfered by upper layer absorber 140a, can be more easily mobile to the outside of width direction W, so as to make to cover The volume in the region of the inside of cover plate 145 becomes much larger.That is, emulsion sheet 145 can more reliably be inhibited to interfere absorbent core 144 The state of affairs of swelling.
In the present embodiment, as described above, absorber 140a in upper layer is compared to lower layer's absorber 140b in width direction W Two sides formed widerly.At this point, in part of the width direction W than lower layer absorber 140b wide non-in the absorber 140a of upper layer Skin side is engaged using bonding agent with back sheet 130.In the occasion, absorb urine in width direction W, lower layer absorber 140b and Swelling, it is all no longer swollen in width direction W if its two ora terminalis reaches the bonding part that the wide part is engaged with back sheet 130 Profit.Thus, it is swelled by side, that is, skin side of the substantial middle part of lower layer absorber 140b layer absorber 140a upward, under The deformation of layer absorber 140b towards width direction W are absorbed.By the deformation that lower layer absorber 140b is protruded towards skin side, formed The region that the discharge port that absorber 140 is more nearly wearer the is abutted i.e. form of urination region can be easy to make to be drained Urine it is most of from at least upper layer groove portion 141a (aftermentioned) of urination region to the inside of lower layer absorber 140b it is mobile simultaneously It is absorbed.Especially, in the present embodiment, when the uptake of the urine in absorber 140 increases (lower layer absorber 140b Swelling progress), infiltration rate reduce when, it is preferred in this way that urination region, which can promote the absorption of urine close to absorber 140, 's.Thereby, it is possible to prevent absorber 140 from losing shape, and be capable of closer to absorber 140 capacity limitation use absorber 140。
In the present embodiment, in turn, as described above, absorber 140a in upper layer is compared to lower layer's absorber 140b in length The two sides of direction L are formed longerly.At this point, in portion of the length direction L than lower layer absorber 140b long in the absorber 140a of upper layer Divide and utilizes bonding agent and back side chip bonding in non-skin side.In the occasion, also lower layer's absorber compared with the absorber 140a of upper layer 140b is same in the occasion that the two sides of width direction W are formed widerly, and lower layer absorber 140b can be assisted to protrude towards skin side Deformation, and can be easy to make the major part of drained urine from upper layer groove portion 141a (aftermentioned) into lower layer absorber 140b Portion is mobile and is absorbed.
In the present embodiment, in length direction L, the surface patch of both ends E1, E2 of urine absorbent pad 100 shown in FIG. 1 The weight per unit area of bonding agent between 120 and back sheet 130, greater than the surface other than both ends E1, E2 of urine absorbent pad 100 The weight per unit area of bonding agent between piece 120 and back sheet 130.Here, both ends E1, E2 are in length direction L away from suction Two ora terminalis of diaper 100 have the region of the amount of specific length inwardly, be in the inside in the region include the both ends of absorber 140 A part region.For example, being 20% or so range of the length that two ora terminalis away from urine absorbent pad 100 have urine absorbent pad 100.It can Think, when absorbent core 144 absorbs urine and swelling is in progress, the expansive force of absorber 140 is become too strong, in length direction L Both ends E1, E2 through-thickness T generate gap, absorbent core 144 is from starting near both ends E1, E2 of length direction L Life is lost shape.But in this urine absorbent pad 100, since both ends E1, E2 in urine absorbent pad 100 are coated with bonding agent in large quantities, institute The state of affairs for causing absorber 140 to lose shape from both ends E1, E2 in the generation gap the both ends E1, E2 can be prevented.By This, can prevent absorber 140 from losing shape, and can close to absorber 140 capacity limitation use absorber 140.
In the present embodiment, there is no the absorbers of absorber 140 when vertical view in width direction W, urine absorbent pad 100 The weight per unit area of bonding agent between surface patch 120 in non-domain of the existence and back sheet 130 can also be greater than urine absorbent pad There are bonding between the surface patch 120 and back sheet 130 in the absorber domain of the existence of absorber 140 when vertical view in 100 The weight per unit area of agent., it can be said that the expansive force of absorber became when absorbent core absorbs urine and swelling is in progress By force, gap is also generated at the both ends of width direction W, the both ends of the W in the width direction of absorbent core 144 are lost shape.But In urine absorbent pad 100, it is coated with the occasion of bonding agent in large quantities at the both ends of the width direction W of urine absorbent pad, this can be prevented The state of affairs that the both ends of the absorber of sample W in the width direction are lost shape.Thereby, it is possible to prevent absorber 140 from losing shape, and can connect Use absorber 140 to the capacity limitation of nearly absorber 140.
In absorber 140, as shown in FIG. 2 and 3 like that, upper layer absorber 140a has from skin side towards non-skin The upper layer groove portion 141a of lateral edge thickness direction T recess.Upper layer groove portion 141a is in through-thickness T perforation in the present embodiment The through hole of layer absorber 140a.Upper layer groove portion 141a is located at portion 112 between the hip of urine absorbent pad 100, and by absorber 140 L extends along its length at the center of width direction W.That is, upper layer groove portion 141a is formed in urination region.It is being drained as a result, Urine spread on surface patch 120 before, i.e., almost without the skin side surface for being stained urine absorbent pad 100, can be by the urine Liquid via upper layer groove portion 141a to the inside of lower layer absorber 140b guide, can close to absorber 140 capacity limitation make With absorber 140.Especially, in the present embodiment, since upper layer groove portion 141a is through hole, thus it is possible to more quickly Urine is directed to the inside of lower layer absorber 140b.
In the present embodiment, groove portion 141a in upper layer is through hole, and then lower layer absorber 140b has from skin side court The lower layer groove portion 141b of non-skin lateral edge thickness direction T recess.Lower layer groove portion 141b is through-thickness T in the present embodiment Penetrate through the through hole of lower layer's absorber 140b.Lower layer groove portion 141b is located at portion 112 between the hip of urine absorbent pad 100, also, by absorbing The center of the width direction W of body 140 and along its length L extend.That is, lower layer groove portion 141b is formed in urination region.In addition, Upper layer groove portion 141a and lower layer groove portion 141b is formed as at least part when looking down and is overlapped.As a result, when the urine drained It, can be by the urine via lower layer's groove portion when reaching lower layer's absorber 140b via the upper layer groove portion 141a of upper layer absorber 140a More internal guidance of the 141b to lower layer absorber 140b, can close to absorber 140 capacity limitation use absorber 140. Especially, in the present embodiment, since lower layer groove portion 141b is through hole, it is thus possible to more quickly inhale urine to lower layer The more internal guidance of acceptor 140b.
In the present embodiment, it is formed as the position of two through holes of upper layer groove portion 141a and lower layer groove portion 141b (i.e. two through holes communicate with each other) consistent with each other when looking down.As a result, foring upper layer groove portion 141a on absorber 140 And the groove portion 141 of lower layer groove portion 141b through-thickness T overlapping.As a result, when the urine drained is via upper layer absorber When the upper layer groove portion 141a of 140a reaches lower layer's absorber 140b, more reliably the urine can be led to lower layer groove portion 141b Enter, it can be to more internal the guiding of lower layer absorber 140b.By guiding urine by lower layer, inhaled by lower layer absorber 140b Urine is received, so as to prevent from returning liquid to upper layer absorber 140a, dry feeling is maintained, that is, reduces and get damp.
The size (length) of length direction L when the vertical view of upper layer groove portion 141a and lower layer groove portion 141b and width side It is contemplated that upper layer absorber 140a and the size etc. of lower layer absorber 140b carry out appropriate adjustment to the size (width) etc. of W.On The width of layer groove portion 141a is usually 5.0~50mm, preferably 10~20mm.The width and upper layer groove portion of lower layer groove portion 141b The width of 141a is equal or smaller, usually 5.0~40mm, preferably 10~15mm.The length of upper layer groove portion 141a Usually 50~300mm, preferably 50~200mm, it is further preferred that 50~150mm.The length of lower layer groove portion 141b Equal length or, usually 30~250mm, preferably 30~150mm shorter than its with upper layer groove portion 141a.Upper layer groove portion The width and equal length of the width of 141a and length and lower layer groove portion 141b are bigger than its, even if thus in lamination Some dislocation occur in the process of layer absorber 140a and lower layer absorber 140b, it also can substantially will be from absorber 140 The size of groove portion 141 of 120 side surface of surface patch viewing keep constant.In addition, since the inner wall in groove portion 141 generates platform The inner surface area of scale, groove portion 141 becomes larger, so, it is formed with the suction urine ability of the absorber 140 in the part of groove portion 141 It is improved.
In general, absorber reverses in order to prevent, after covering absorber by emulsion sheet, takes heat fusing sometimes Or the means of compression.But when executing these means, the volume of absorber may be reduced, or absorb urine and Absorber may occur intentional deformation and lead to urethral leakage when starting swelling.Thus, in the present embodiment, in order to prevent Such state of affairs does not preferably implement these means substantially.
