Disposable wearing items

The present invention relates to a disposable wearing article.

Conventionally, there is known a disposable wearing article (paper diaper) having a non-skin contact surface in the longitudinal direction and the transverse direction, and on the skin abutting surface and the opposite side thereof, and including a front waist region and a back waist portion. a region, a crotch region located between the front and rear waist regions, and a liquid-absorbent structure extending from the crotch region toward the front and rear waist regions. For example, the front and rear waist regions of the disposable diaper disclosed in Patent Document 1 are divided into a first expansion and contraction region, a second expansion and contraction region, and a third expansion and contraction region, and the first expansion and contraction region extends in the waistline direction along the waist opening edge portion. The telescopic region is adjacent to the first expansion and contraction region and extends in the waistline direction. The third expansion and contraction region is adjacent to the second expansion and contraction region and extends in the waistline direction. The relationship between the expansion and contraction force of the expansion and contraction regions is disclosed as 3 expansion and contraction area ≧ second expansion and contraction area> first expansion and contraction area.

The diaper has a small expansion and contraction force of the first elastic force on the side of the waist opening of the upper end in the longitudinal direction, so that the waist opening can be easily expanded, and the third elastic force on the side of the leg opening edge becomes large. ,because This allows the disposable diaper to conform to the wearer's body at the edge of the leg opening.

However, there are also newborns or skin-sensitive people in the diaper wearer, and therefore there are skin problems such as redness of the skin at the point where the waist elastic body contacts. Therefore, it is desirable to have a disposable diaper having a low contraction portion and a high contraction portion in the lateral direction.

Accordingly, an object of the present invention is to provide an article for wearing which is improved in the prior art and does not cause skin problems.

In order to achieve the above object, the present invention relates to a disposable wearing article having a longitudinal direction and a lateral direction, and a non-skin abutting surface of the skin abutting surface and the opposite side thereof, and including a front waist region and a rear portion. a waist region, a crotch region located between the front and rear waist regions, and a liquid-absorbent structure extending from the crotch region toward the front and rear waist regions.

The disposable wearing article of the present invention is characterized in that at least one of the front and rear waist regions has a pair of first side elastic regions located on both side edges of the liquid-absorbent structure. And a waist elastic body extending in the lateral direction in the first side elastic region; at least one of the waist elastic bodies having a cut off in the lateral direction The low-contraction portion of the portion and the high-elastic portion without the cut portion.

The high-elasticity portion of the waist elastic body has a large cross-sectional area, and the low-elasticity portion of the waist elastic body has a cross-sectional area smaller than a cross-sectional area of the high-elasticity portion. Therefore, the waist elastic system can be pressurized as long as the area to be removed by the cutting is large, that is, the contraction force of the super-low-elastic portion and the contraction force of the high-elastic portion can be different.

The front and rear waist regions have a plurality of the waist elastic bodies in the longitudinal direction, and the waist elastic body located below the longitudinal direction of the liquid-absorbent structure has the low-elasticity portion, and is located at the lower side than the suction portion. The waist elastic body on the upper side in the longitudinal direction of the liquid structure does not have the low-elasticity portion. Therefore, the wearable article can be attached to the wearer's waist while preventing the waist elastic body from strongly contacting the wearer's foot circumference on the lower side in the longitudinal direction than the liquid-absorbent structure. The upper side of the longitudinal direction of the liquid-absorbent structure is formed, and it is possible to suppress the article for wearing from falling downward and falling.

The liquid-absorbent structure has a core material and a side panel located on the outer side in the lateral direction of the core material, and the one waist region has a second side elastic region, and the first side elastic region and both sides of the core material The second side elastic region overlaps with the side panel when viewed from above, and the contraction force of the portion of the waist elastic body located in the second side elastic region is larger than the contraction force of the low expansion and contraction portion. Therefore, a pair of The 2 side elastic region is crimped to the wearer's body, and a gap between the body and the waist region can be suppressed to prevent leakage of excrement.

An inelastic region where the waist elastic body does not exist is disposed inside the pair of second side elastic regions, and the core material and the inelastic region overlap each other in a plan view. Therefore, deformation of the core material can be suppressed, and the absorption area can be prevented from being reduced.

The low-elasticity portion of the waist elastic body has a cut portion extending in the lateral direction between both side edges of the waist elastic body in the longitudinal direction. Therefore, since the cut portions are not located on both side edges of the front and rear waist elastic bodies, it is possible to prevent the sheets from being caught at the ends of the cut portions.

The wearing article has a waist opening and a pair of leg openings, wherein the front and rear waist regions have a plurality of the waist elastic bodies in the longitudinal direction, and a position of the cutting portion of the waist elastic body located on the leg opening side. Further, in the waist elastic body, the positions of the cut portions of the waist elastic body adjacent to the waist opening side are different in the lateral direction. Therefore, it is possible to prevent the contraction force of the waist elastic body from being locally increased, and it is possible to prevent the part of the waist elastic body from strongly contacting the wearer's foot circumference, and to attach the wearing article to the wearer's foot circumference.

According to the disposable wearing article of the present invention, at least one waist elastic body has a low expansion and contraction in the lateral direction Part, and a high-stretching portion that does not have a cut portion. Therefore, since the waist elastic body has a low expansion and contraction portion, the waist elastic body can be prevented from strongly contacting the wearer's body, and the wearing article can be attached to the wearer's body with the high expansion and contraction portion. This prevents skin problems such as redness of the skin.

Each of the following embodiments relates to the disposable wearing article (paper diaper) shown in FIGS. 1 to 6, which is not only an indispensable structure of the invention. The invention also includes alternative and preferred embodiments.

<First embodiment>

1 and 2, the disposable diaper 10 has a longitudinal direction Y and a lateral direction X intersecting (orthogonally), and includes a skin facing surface and a non-skin opposing surface opposed thereto and a ring extending in the waistline direction. The elastic waist piece 11 and the absorbent base (absorbent structure) 12 attached to the skin side of the elastic waist piece 11 , the front waist region 13 , the rear waist region 14 , and the crotch between the front and rear waist regions 13 and 14 Area 15.

The elastic waist panel 11 includes a front waist panel 16 having an elastic band function and forming a front waist region 13, and a back waist panel 17 forming a rear waist region 14. The front and rear waist panels 16, 17 have inner end edges 16a, 17a, outer end edges 16b, 17b, and a rectangular shape defined by the side edges 16c, 17c. The side edges 16c of the front waist piece 16 and the side edges 17c of the rear waist piece 17 are superposed on each other, and a waist opening 19 and a pair of legs are formed at side seams 18 which are arranged side by side in the longitudinal direction Y. The opening 20 is connected by well-known means, such as various embossing means such as hot embossing and ultrasonic.

Each of the front and rear waist panels 16 and 17 includes an inner sheet 21 on the opposite side of the skin and an outer sheet 23 on the non-skin facing side. For the inner and outer sheets 21, 23, an SMS (spunbond, meltblown, spunbond) fiber nonwoven fabric, a spunbonded nonwoven fabric or a hot air fiber nonwoven fabric, a plastic sheet, an apertured plastic sheet, and the like having a mass of 15 to 30 g/m ² can be used. Stacked sheets and the like.

Between the inner and outer sheets 21, 23 of the front and rear waist panels 16, 17 are respectively provided with a plurality of waist elastic bodies 27 in a line shape, a strand shape, or a ribbon shape, and the waist elastic bodies 27 can be oriented in the lateral direction. X is stretched, and the front and rear waist panels 16, 17 are elastic at least in the lateral direction X. The waist elastic body 27 has an upper waist elastic body 27A extending in the lateral direction X along the waist opening 19, and a lower waist elastic body 27B which is in the upper waist elastic body 27A and the inner waist elastic body 27B. The edges 16a, 17a extend in the lateral direction X. The upper stretchable region 28A is formed in a region where the upper waist elastic body 27A is disposed, and the lower stretch region 28B is formed in a region where the lower waist elastic body 27B is disposed. The upper waist elastic body 27A is continuous between the side edges 16c and 17c of the front and rear waist regions 13 and 14 in the lateral direction X. The lower waist elastic body 27B is continuous between the both side edges 16c and 17c of the front and rear waist regions 13, 14 and both side edges of the liquid-absorbent core 43, and is continuous in the lateral direction X.

The lower waist elastic body 27B has an outer end portion 32 and inner end portions 34, which are located at both side edges 16c, 17c of the front and rear waist regions 13, 14 which are transverse to the outer end portion 32. X is opposed to each other, and a part of the front and rear waist regions 13 and 14 is cut and contracted to define a non-elastic region 36 that is not present. Since the inelastic region 36 is located at the central portion of the front and rear waist regions 13, the contraction force of the lower waist elastic body 27B does not directly act on the absorbent base 12 on the skin facing surface of the front waist panel 16, and wrinkles are formed. It can suppress the absorption performance caused by the contraction force.

As a method of forming the inelastic region 36, for example, before and after Both end portions of the waist regions 13 and 14 in the lateral direction X form a coating region of a hot-melt adhesive for fixing the lower waist elastic body 27B, and on the other hand, a central portion of the front and rear waist regions 13 and 14 in the lateral direction X is formed. In the non-coated region of the hot-melt adhesive, when the lower waist elastic body 27B (only one portion) located in the non-coated region is cut, the lower waist elastic body 27B is automatically contracted (rebounded). Thus, the inelastic region 36 in which the lower waist elastic body 27B having the contracting force is substantially absent is formed in the non-coated region.

As the waist elastic body 27, for example, an elastic material having a line shape, a strand shape, or a ribbon which can be stretched to a state of 1.5 to 3.5 times in a state where the thickness is 470 to 1240 dtex can be used. The conditions such as the thickness of the waist elastic body 27, the stretching ratio, and the separation size (pitch) between the elastic members can be appropriately changed. However, in order to stably wear the body of the wearer, it is preferable to set the conditions of the respective elastic bodies so that the upper portion is set upward. The expansion and contraction force (contraction force) of the upper telescopic region 28A by the waist elastic body 27A is larger than the expansion and contraction force of the lower telescopic region 28B by the lower waist elastic body 27B. By setting the stretching force of the waist elastic body 27 in this way, since the elastic force of the upper waist elastic body 27B on the side of the waist opening 19 is large, it is possible to prevent the disposable diaper 10 from being displaced downward and to prevent the lower waist portion on the side of the leg opening 20 The elastic force of the elastic body 27B becomes excessive.

4 is a partial enlarged view of the rear waist region 14. In addition, the description of the front waist region 13 is omitted, but has the same configuration as the rear waist region 14. In the inner side in the lateral direction X of the lower waist elastic body 27B, the cut portion (through hole) 104a penetrating the lower waist elastic body 27B is not formed in the thickness direction, and the outer side in the lateral direction X is formed in the thickness direction. A cut portion 104a penetrating the lower waist elastic body 27B is formed.

In the lower waist elastic body 27B, the portion where the cut portion 104a exists loses the stretchability, while the remaining portion of the lower waist elastic body 27B maintains the stretchability.

When the lower waist elastic body 27B is formed with the cut portion 104a, the cross-sectional area of the lower waist elastic body 27B in the portion having the cut portion 104a is smaller than the cross-sectional area of the lower waist elastic body 27B before the cut portion 104a is formed. The stretching force (elastic force) is largely lowered as compared with the portion where the cutting portion 104a is not formed.

In the lower waist elastic body 27B, the portion having the cut portion 104a is a low stretch portion 51 having a small expansion and contraction force (contraction force), and the portion having no cut portion 104a is a stretch force (contraction force) ratio of the low stretch portion 51. The large high-elastic portion 52 is alternately arranged in the lateral direction X, and the low-elastic portion 51 and the high-elastic portion 52 are alternately arranged.

Therefore, according to the disposable diaper 10, the plurality of lower waist elastic bodies 27B have the low expansion and contraction portion 51, so that the lower diaper elastic body 27B can be prevented from strongly contacting the wearer's body while the diaper 10 is made with the high expansion and contraction portion 52. Fits the wearer's body. Further, since the low-elasticity portion 51 of the lower waist elastic body 27B is also a portion having a small bending rigidity in the thickness direction, it has flexibility and can greatly expand the leg opening 20 with a small force. Therefore, when the disposable diaper 10 is worn, it is easy to put the foot into the leg opening 20. Further, if the area of the lower waist elastic body 27B that is cut and removed is large, the difference between the contraction force of the low stretch portion 51 and the contraction force of the high stretch portion 52 can be increased. Moreover, when the disposable diaper 10 is worn, When the cut portions 104a and 104b are opened, it is possible to prevent the inside of the disposable diaper 10 from being heated.

The cut portion 104a is extended in the lateral direction X between the side edges 29 of the lower waist elastic body 27B in the longitudinal direction Y. Therefore, since the cut portion 104a is not located on both side edges 29 of the lower waist elastic body 27B, the inner and outer sheets 21, 23 can be prevented from being caught at the cut portion 104a.

Further, the lower waist elastic body 27B has a lower elastic portion 51 than the lower surface of the absorbent base 12 of the liquid-absorbent structure in the longitudinal direction Y, and is located above the absorption axis 12 in the longitudinal direction Y. The lower waist elastic body 27B does not have the low expansion and contraction portion 51. Therefore, it is possible to prevent the lower waist elastic body 27B from strongly contacting the wearer's foot circumference while adhering to the lower side of the wearer base 12 in the longitudinal direction Y, and to attach the disposable diaper 10 to the wearer's waist circumference, and the other On the other hand, it is possible to suppress the paper diaper 10 from being displaced downward toward the upper side of the absorbent substrate 12 in the longitudinal direction Y.

In the front and rear waist regions 13 and 14, in the lateral direction X, a first stretchable region (first elastic region) 29B is formed in a portion where the cut portion 104a is formed, and a stretchable force ratio is formed in a portion where the cut portion 104a is not formed. 1 The second expansion and contraction region (second elastic region) 29C having a larger expansion and contraction region 29B.

As described above, by forming the front and rear waist regions 13 and 14, the magnitude of the expansion and contraction force (contraction force) of each of the expansion and contraction regions is the upper expansion and contraction region 28A>the second expansion and contraction region 29C>the first expansion and contraction region 29B.

The first expansion and contraction region 29B is in the lateral direction X and is disposed in the slave The side edges 12C of the absorbent substrate 12 are spaced between the side edges 16c, 17c of the front and rear waist regions 13, 14. The second stretchable region 29C is disposed between the first stretchable region 29B and the both side edges 43C of the liquid-absorbent core 43 of the core material, and is disposed to overlap the side flap 48 to be described later in a plan view. Therefore, the pair of second expansion and contraction regions 29C are pressed against the wearer's body, and it is possible to suppress a gap between the body and the front and rear waist regions 13 and 14 and prevent excretion from leaking out.

In the inner sheet 21, the cut portion 104b penetrating the inner sheet 21 is formed at a position where the lower waist elastic body 27B overlaps the cut portion 104a in plan view, so that the air permeability can be improved. On the other hand, since the outer sheet 23 does not have a cut portion, it is possible to prevent excretion from leaking out.

Referring to Fig. 2, the absorbent substrate 12 comprises: front and rear end portions 12A, 12B attached to the front and rear waist panels 16, 17; the liquid-absorbent core 43 extending at least in the crotch region 15 in the longitudinal direction Y; the top sheet 44 is located The surface of the liquid-absorbent core 43 facing the skin is formed of a hydrophilic fiber non-woven fabric; the back sheet 45 is located on the non-skin-facing side of the liquid-absorbent core 43 and is made of hydrophobic or liquid-impermeable fibers. The non-woven fabric is formed; and the leakage preventing sheet 46 is disposed between the liquid-absorbent core 43 and the back sheet 45, and has a size of at least the entire surface of the liquid-absorbent core 43 facing the back sheet 45. As the top sheet 44 and the back sheet 45, various well-known fiber nonwoven fabrics such as an SMS fiber nonwoven fabric or a spunbonded nonwoven fabric can be used.

The liquid-absorbent core 43 is a mixture of superabsorbent polymer particles and fluff pulp, and has a semi-rigid rigidity higher than that of the sheet member constituting the disposable diaper 10. Further, the liquid-absorbent core 43 is formed in the longitudinal direction Y The central portion has a narrow-web shape, and the entire portion is covered with a liquid-diffusing sheet 47 such as a thin paper. The top sheet 44 and the back sheet 45 extend outward from the peripheral portion of the liquid-absorbent core 43, which are superposed on each other and joined by a hot-melt adhesive (not shown), thereby forming the side flaps 48 and the ends The fin piece 49 extends from the both side edges 43C of the liquid-absorbent core 43 toward the outer side in the lateral direction X, and the end fin 49 extends from the both end edges of the liquid-absorbent core toward the outer side in the longitudinal direction Y. .

In the paper diaper 10, the inner sheet 21 is formed at a position overlapping the cut portion 104a of the lower waist elastic body 27B in a plan view, and the cut portion 104b penetrating the inner sheet 21 is formed. At the time of observation, the cut portion 104c is formed on the inner sheet 21 which does not overlap the lower waist elastic body 27B. Therefore, since the area of the cut portions 104b and 104c penetrating the inner sheet 21 can be expanded, the air permeability can be improved.

Further, the cut portions 104a, 104b, and 104c are arranged to be inclined in the lateral direction X and the longitudinal direction Y. Therefore, when the lower waist elastic body 27B is contracted, the cut portions 104a, 104b, and 104c are opened in the thickness direction, and the inside of the disposable diaper 10 can be prevented from being heated. Although not shown in the drawings, the cut portion 104a may be formed to extend in the lateral direction X in an inclined manner between the side edges 29 of the lower waist elastic body 27B.
