Description

  The present invention relates to an absorbent article. More specifically, the present invention relates to an absorbent article having a relatively small amount of absorption, such as a light incontinence liner, a sanitary napkin, or a urine absorbing pad having an embossed squeezed area on its upper surface.

Recently, in an absorbent article including an incontinence liner or pad for mild incontinence symptoms, in order to improve the fit to the body, the squeezing strip in the longitudinal direction of the article is placed on the body-side liner of the absorbent article. The technique of providing a zone has been widely adopted.
Such squeezed zone has a high squeeze groove and a low squeeze groove which are continuously arranged in the width direction of the squeeze zone and alternately arranged in the longitudinal direction to control the diffusion of the liquid to be absorbed. (For example, patent document 1). However, this technique has a disadvantage that the presence of the compressed strip region increases the rigidity of the absorbent core located therebelow. In addition, there is an absorbent body in which a groove having first and second portions having different compression is formed (see, for example, Patent Document 2). Furthermore, there is a sanitary napkin in which low-pressure grooves and high-pressure grooves are discontinuously arranged in the longitudinal direction at intervals in the compressed groove (for example, Patent Document 3). In addition, there is an absorbent article in which a pair of left and right embossed grooves is formed to prevent stiffening of the embossed groove portion and to prevent liquid diffusion (for example, Patent Document 4).

Patent No. 3053561 publication Japanese Patent Application Publication No. 2002-53172 Japanese Patent Application Publication No. 2003-38555 Japanese Patent Application Publication No. 2003-265518

Although these absorbent articles having a prior art squeeze zone are improved with respect to diffusion control for liquid absorption, they are not sufficient to eliminate the hardness of the squeezed part. Furthermore, due to the expansion of the absorbent core due to the absorption of the liquid, the shape of the squeezed part tends to be lost, and it still has the problem and drawback that the effect is easily lost during the next liquid absorption or during use. .
Therefore, the present invention eliminates the hardness of the squeezed part formed on the body-side surface of the absorbent article, thereby absorbing the liquid such as urine when wearing the absorbent article, before and after the liquid and the left and right sides of the liquid. Control of flow and diffusion in the direction is improved compared to the conventional method, and it is possible to reliably prevent side leakage of liquids, maintain the effect of the compressed part even when there are multiple liquid absorptions, It is an object of the present invention to provide an absorbent article having excellent shape retention.

In order to solve the above-described problem, an absorbent article of the present invention is an absorbent article including a top sheet, a back sheet, and an absorbent body disposed therebetween, and the absorbent article is formed on the top sheet. Along with the longitudinal direction of the absorbent article, it has at least a pair of compressed strip regions formed at predetermined intervals, and each of the compressed strip regions includes a plurality of high compression regions and low compression regions. And at least one boundary line between the high compression region and the low compression region has a portion that protrudes toward the inside of the high compression region. It is sufficient that the high compression region has a closed shape. In this compressed strip region, it is preferable that the low compression region is formed so as to surround the high compression region. This boundary line may be a straight line or a curved line.
In another embodiment of the present invention, each of the compressed strip regions is composed of a plurality of high compression regions and low compression regions, and at least one of the boundaries between the high compression regions and the low compression regions is a low compression region. It has a part which becomes convex toward the inside. In this squeezed region, it is sufficient that the low compression region has a closed shape. In the compressed strip region, it is preferable that the high compression region is formed so as to surround the low compression region. This boundary line may be a straight line or a curved line.
And in the squeeze zone of the absorbent article of the present invention, if the angle with respect to the perpendicular of the wall formed by the boundary between the high compression region and the low compression region is 10 ° to 45 °, a favorable effect on the fit to the body Can be demonstrated.
In another aspect of the present invention, the ratio of the total area of the high compression region to the compressed strip region is preferably 5 to 30%, more preferably 5 to 15%.

Furthermore, in another aspect of the present invention, the thickness of the high compression region is 20 to 70% of the thickness of the uncompressed region in the vicinity of the compressed region, and the thickness of the low compressed region is in the vicinity of the compressed region. It is preferable that it is 40 to 90% of the thickness of the area | region which is not squeezed.
The high compression region of the absorbent article of the present invention is such that each area of the high compression region is smaller than the area of other shapes having the same length as the circumference of the shape of the high compression region. It is preferable that it is formed to have a simple shape. The shape of such a high compression region can be selected from concave polygons including a star shape.

  In the absorbent article including the urine absorbing pad or liner of the present invention, the emboss applied to the upper surface is formed from at least one pair of compressed strip regions extending in the longitudinal direction, and each of the compressed strip regions is an absorbent article. It is formed at a predetermined interval in the width direction. The squeezed area is composed of a high compression area, that is, a high pressure groove, and a low compression area, that is, a low pressure groove, and has a unique relationship between the high pressure groove and the low pressure groove. In this invention, it has the structure which the low pressure squeeze surrounds the circumference of a high pressure squeeze, or the high pressure squeeze surrounds the circumference | surroundings of a low pressure squeeze. It is sufficient that the high pressure squeezing groove or the low pressure squeezing groove is arranged in a dot shape in the squeezing region, but the boundary line between the high pressure squeezing and the low pressure squeezing is indented in the concave polygon or the inner side of the high pressure squeezing It is configured to have such a curved shape. By configuring the relationship between the high and low pressure grooves in this way, the biting between the top sheet of the absorbent article and the absorbent core becomes good, and the shape retention of the compressed strip area is improved. That is, when the absorbent article absorbs the liquid, it is possible to prevent the occurrence of inconvenience such that the absorbent core expands and the shape of the compressed portion is lost. As a result, the squeezed area of the absorbent article of the present invention will provide an excellent effect on the fit of the body and appropriately diffuse the absorbed liquid even during the first and subsequent liquid absorption. It has a great effect that it can be controlled.

  Furthermore, in relation to the shape of the high-pressure squeezes, the shape of the high-pressure squeezes is formed in such a shape that at least a part of the boundary is convex toward the inside of the high-pressure squeeze, compared with the conventional squeeze zone Then, the area is reduced with respect to the circumferential length of the shape of the high-pressure squeezed groove, so that the hardness, that is, the rigidity of the squeezed portion can be reduced while maintaining the shape of the compressed portion almost the same as before use. Become. As a result, it becomes difficult for the embossing composed of the compressed strip area to disappear during use, the liquid diffusibility effect is sustained, and not only the usability but also the cosmetic properties are excellent.

Several embodiments of the present invention will be described below with reference to the accompanying drawings. In the following description, the incontinence pad will be described as an example, but it should be understood that the incontinence liner can also be applied. The pad and liner of the present invention can also be applied to products that absorb excreta including urine such as sanitary napkins and disposable diapers.
In this specification, “longitudinal direction of absorbent article”, “longitudinal direction of pad” and the like mean directions extending from the front and back of the wearer when the absorbent article and pad are worn, The “width direction”, the “width direction of the absorber” and the like mean a direction transverse or orthogonal to the longitudinal direction.

  FIG. 1 is a plan view schematically showing an entire typical incontinence pad 10 according to the present invention. The pad 10 includes a top sheet 11 facing the body side, a back sheet 12 facing the clothes side, and an absorbent core 13 disposed therebetween. The overall shape of the pad 10 can be selected from various shapes such as a rectangular shape and an I-shape. The absorbent core 13 has a predetermined width and extends in the longitudinal direction of the pad 10. The absorbent core 13 may have a general shape such as an hourglass shape or an I-shape. The absorbent core 13 may comprise a hydrophilic fiber matrix of a cellulose fluff web, such as a wood pulp fluff, mixed with particles of a superabsorbent material, commonly known as a superabsorbent material. Synthetic fibers or polymer fibers may be used instead of the wood pulp fluff. The top sheet 11 only needs to be formed from a general non-woven fabric and is formed from a material that does not irritate the wearer's skin with a soft feel because it is on the side facing the wearer's skin. It is preferable. The backsheet 12 may be formed of a material that is impermeable to liquid so that the liquid retained in the absorbent core 13 has a waterproof function so that the liquid does not leak into the underwear, such as a polyethylene film. It is preferably formed from a thin plastic film or a cross-like flexible liquid impervious film. The pad 10 shown in FIG. 1 shows only the most basic structure, and various configurations can be added depending on the amount of liquid such as urine to be absorbed. For example, a three-dimensional gather may be formed to more reliably prevent leakage from the side of the pad. Further, a transfer sheet may be provided between the top sheet 11 and the absorbent core 13 so that urine can be dispersed and absorbed more quickly. Further, a general slip stopper for fixing the pad 10 to the underwear or the like may be disposed below the back sheet 12, and a release paper may be disposed below the slip stopper so as to cover it. . Additional components can be modified as appropriate according to the intended use, and such techniques are well known in the art and will not be described in further detail.

  On the top sheet 11 side of the pad 10, a pair of compressed strip regions 14 are formed along the longitudinal direction of the pad 10 at a predetermined interval in the width direction of the pad 10. The compressed strip region 14 is formed by embossing the top sheet 11 side of the pad 10. The squeeze zone 14 is formed by embossing in two stages composed of a plurality of high-pressure squeezes and low-pressure squeezes. In the present specification, the high-pressure squeezed means a high-compression region compressed with a predetermined force to form a groove, and the low-pressure squeezed has a lower density than the high-compression region compared to the high-compression region. This means a low-compression region that has been compressed. In the squeezing zone 14, the high pressure squeezing groove or the low pressure squeezing is arranged in a dot shape so that the low pressure squeezing surrounds the high pressure squeezing or the high pressure squeezing surrounds the low pressure squeezing. It only has to be adapted. In a high / low pressure slot relationship, the boundary between the high pressure slot and the low pressure slot forms a concave polygon, or at least one of the boundaries has a straight line or curve that is recessed inwardly in the center of the pad. It is preferable to form a different shape.

  FIG. 2 is an enlarged view of a portion of the squeeze zone 14 of the pad 10 illustrated in FIG. 1 that represents the first embodiment of the present invention. The squeezed region 14 is composed of a high-pressure squeezed groove 15 and a low-pressure squeezed groove 16 formed by being compressed with a force smaller than that of the high-pressure squeezed groove 15. In this embodiment, the boundary line between the high pressure groove 15 and the low pressure groove 16 has a star shape. That is, the high pressure squeezed grooves 15 have a star shape, and are irregularly arranged so as to be surrounded by the low pressure squeezed grooves 16 in the compressed strip region 14.

  The thickness of the pad in the high-pressure groove 15 is preferably 20 to 70% of the thickness of the pad 10 in the compressed area 14, that is, in the vicinity of the area where the embossing is not performed. On the other hand, the thickness of the low-pressure squeezed groove 16 is preferably 40 to 90% of the thickness of the pad 10 in the region where the embossing in the vicinity of the compressed strip region 14 is not applied. Within these ranges, the thickness of the high and low pressure squeezed portion is appropriately selected and embossed to obtain a preferred squeezed region 14 including the high pressure squeezed groove 15 and the low pressure squeezed groove 16.

The ratio of the total area of the plurality of high-pressure grooves 15 to the compressed strip area 14 is preferably 5 to 30% with respect to the area of the compressed strip area 14, and is 5 to 15% of the area of the compressed strip area 14 Is more preferable. The greater the area of the high-pressure squeezed groove 15, the stronger the squeezed part becomes. That is, the rigidity of the pressing part is increased. Therefore, in order to reduce the rigidity of the squeezed portion, it is preferable that the area occupied by the high-pressure squeezed groove 15 with respect to the squeezed strip area 14 is as small as possible within the range in which the effect of the squeezed strip area 14 can be exhibited.
The peripheral length of one unit of the high-pressure groove 15 with respect to the low-pressure groove 16 is preferably 5 to 80 mm, and more preferably 10 to 30 mm. The boundary line between the high-pressure groove 15 and the low-pressure groove 16 in this embodiment, that is, the shape of the high-pressure groove 15 is a star shape. Compared to the case of, for example, a convex polygon or a circle having the same peripheral length as the boundary line between the high-pressure groove 15 and the low-pressure groove 16, the area of the high-pressure groove 15 per unit is small. Thus, by selecting a shape having a small area with respect to the peripheral length as the shape of the high-pressure squeezed groove 15, it becomes easy to maintain the shape of the squeeze zone 14 and the rigidity of the region is reduced. .

ここで、Ｒは圧縮領域の形状の最大幅を表し、Ｌは境界線の周長、Ｓは面積、Ｓ/Ｌは面積と周長の比を表している。以上の表から、周長が５から８０ｍｍの範囲内においては、本願発明の例の面積・周長比Ｓ/Ｌは、凸多角形などの比較例の形状の面積・周長比に比べて小さいことは明白である。すなわち、本願の圧縮領域形状の単位面積当たりの周長は、円などを含む凸多角形のものより相当に長くなるといえる。例えば、本願発明の例１の圧縮領域形状(ａ）と比較例１の楕円形状（ｃ）とを比較すると、本願発明の例の面積・周長比S/Ｌは、比較例１のほぼ１/３となっている。本発明において、周長Lが３０ｍｍである場合、面積・周長比S/Lは１．１以下であることが好ましい。 FIG. 3 is a diagram illustrating an example of the shape of a compression region that forms a boundary line between a high-pressure groove and a low-pressure groove, and a shape such as a convex polygon for comparison with this. is there.

In Table 2, Comparative Examples 1, 2, and 3 are shown in FIG. Numerical values respectively corresponding to the illustrated (c), (d), and (e) are shown.

Here, R represents the maximum width of the shape of the compressed region, L represents the perimeter of the boundary line, S represents the area, and S / L represents the ratio of the area to the perimeter. From the above table, in the range of the circumference of 5 to 80 mm, the area / circumference ratio S / L of the example of the present invention is compared with the area / circumference ratio of the shape of the comparative example such as the convex polygon. It is obvious that it is small. That is, it can be said that the perimeter per unit area of the compression region shape of the present application is considerably longer than that of a convex polygon including a circle or the like. For example, when the compression region shape (a) of Example 1 of the present invention is compared with the elliptical shape (c) of Comparative Example 1, the area / circumference ratio S / L of the example of the present invention is approximately 1 of Comparative Example 1. / 3. In the present invention, when the circumferential length L is 30 mm, the area / circumference ratio S / L is preferably 1.1 or less.

Unlike the case shown in FIG. 4A, the high-pressure groove 15 'has a high-pressure groove 15' formed around the low-pressure groove 16 '. That is, the compressive force between the central bottom surface portion 19 and the surrounding portion is opposite to that in the second embodiment, and is formed so that the high pressure groove 15 'surrounds the low pressure groove 16'. It is like that. Even if it is this embodiment, it is preferable that the ratio of the area of the whole several high pressing groove 15 'with respect to the pressing strip area 14 is 5 to 30% with respect to the area of the pressing strip area 14, More preferably, it is a pressing strip. 5 to 15% of the area 14 area. The angle θ ′ formed by the wall 17 ′ that forms the boundary between the high-pressure groove 15 ′ and the low-pressure groove 16 ′ and the perpendicular is preferably 10 ° to 45 ° as in the first embodiment. .
When at least two steps are formed at a predetermined angle in the compressed strip area 14 in this way, the biting between the top sheet and the absorbent core is improved, and normal or conventional embossing is applied. Compared to the above, the shape retention of the squeezed region is further improved.

  In 2nd, 3rd and 4th embodiment, the ratio of the area of the several high pressing groove 20, 21, 22 whole with respect to the pressing strip area 14 is the area of the pressing strip area 14 similarly to 1st Embodiment. Is preferably 5 to 30%, more preferably 5 to 15% of the area of the pressed strip region 14. The angle θ formed by the wall 17 that forms the boundary between the high-pressure grooves 20 and 21 and the low-pressure groove 16 and the perpendicular is 10 ° to 45 ° as in the first embodiment. Moreover, the thickness of the pad in the high pressure squeezing grooves 20 and 21 may be 20 to 70% of the thickness of the pad 10 in the squeezed region 14, that is, in the vicinity of the embossed region where the embossing is not performed. preferable. On the other hand, the thickness of the low-pressure squeezed groove 16 is preferably 40 to 90% of the thickness of the pad 10 in the region where the embossing in the vicinity of the compressed strip region 14 is not applied.
