Description

  The present invention relates to an absorbent article in which leakage of body fluid is suppressed and fit is improved.

  In general, adult paper diapers include a tape stop type, a urine picking pad, a pants type, and the like, and these paper diapers are appropriately selected and used according to the need for care in excretion of the wearer. These absorbent articles are composed of a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber disposed between the two sheets. By adopting such a configuration, body fluid such as urine passes through the top sheet of the absorbent article and is absorbed by the absorbent body, and does not leak to the outside by the back sheet.

  By the way, tape diapers and pants-type disposable diapers may be used alone or in combination with a urine-absorbing pad on the inside. In most cases, a certain urine absorbing pad is used while being stacked on the top sheet. This is because the cost per sheet of diaper is high. After excrement is absorbed and held by a urine collection pad that is cheaper than tape-type or pants-type diapers, only the urine collection pad is replaced. This is because, even after excretion, it is not necessary to replace a higher-cost tape-type or pants-type paper diaper, and the paper diaper can be used economically at a low cost.

  Here, the urine removal pad used in combination with the pants-type disposable diaper needs to be stored inside the three-dimensional gather of the interior pad of the disposable diaper, so the length, width, and area of the urine removal pad are both taped. It must be smaller than the urine collection pad used with the type of disposable diaper. And since the size of the urine collecting pad is small, the absorbed urine is likely to spread, and there is a problem that it is likely to leak from the front, rear, left and right ends of the urine collecting pad. For example, the following inventions have been disclosed as an invention that addresses such a problem of side leakage and an improvement in absorption performance.

  For example, Patent Document 1 discloses an absorbent article having a longitudinal direction and a width direction, in which a predetermined convex portion and a concave portion are continuous in a longitudinal direction of the absorbent article in a region including at least a body fluid discharge portion. A processed absorbent article is disclosed. Further, in Patent Document 2, a top sheet bulges upward from the absorber and extends in the width direction, and a plurality of protrusions lined up with a predetermined dimension in the longitudinal direction, and a width direction between the protrusions. An absorbent article having a plurality of recesses extending in the direction and having a large number of openings penetrating in the thickness direction in the top sheet is disclosed. Further, in Patent Document 3, the absorbent body has a relatively high basis weight and has a relatively low basis weight surrounding each of the plurality of predetermined protrusions, which are convex on the backsheet side, An absorbent article having a block region in which a plurality of block structures each including a groove portion recessed from the back sheet side toward the top sheet side are arranged in the vertical direction is disclosed.

  However, none of the absorbent articles described in Patent Documents 1 to 3 satisfy all of the diffusibility in the longitudinal direction of body fluid in the absorbent body, the absorption speed, the side leakage prevention performance, the liquid return property, and the fit property. . In addition, by providing a convex portion on the absorber, it functions as a leak-proof wall, and even when a large amount of body fluid is excreted at a time, leakage from the end can be prevented. When the pad is folded in half or the like, there is a problem that the convex portions of the absorbent body overlap each other and the convex portions are crushed.

  (5) A fifth aspect of the present invention is the absorbent article according to any one of (1) to (4), characterized in that it is a urine picking pad for pants used in combination with a pants-type paper diaper. It is what.

  In the absorbent article of the present invention, since the absorbent body has a plurality of linear convex three-dimensional portions extending along the longitudinal direction, the diffusibility of the body fluid in the longitudinal direction is improved and the body fluid absorption rate is increased. As a result, side leakage and the like can be effectively prevented, and the liquid return property can be improved. Moreover, since the said convex three-dimensional shape part has the dimension and height of a predetermined longitudinal direction and the width direction, the fitting property of an absorbent article is also maintained favorable. In addition, the convex three-dimensional shape portion is arranged so that the convex three-dimensional shape portions before and after the fold line do not overlap when the absorbent article is folded in the longitudinal direction.
