[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable diaper having a stool receiving recess formed in an absorbent body.

[0002]

2. Description of the Related Art Conventionally, excreted stool does not spread between the skin and the diaper skin to prevent discomfort.
There is known a diaper in which a concave portion is provided in a portion of the absorber where the buttocks are located, and stool is received in the concave portion.

[0003]

In this diaper, the liquid-permeable top sheet covering the absorber is made to follow the shape of the concave portion. However, such a recess is not deep enough that the contour is not clear or the depth is shaded,
For this reason, it is not always easy to distinguish the recess from other parts, and there is a problem in that when the diaper is worn, it is troublesome to properly apply the recess to the anal part.

Therefore, the present invention solves the above-mentioned problem by making the shape and color of the joining area between the topsheet and the absorber in the recess different from those other than the recess to facilitate the identification of the recess. Is an issue.

[0005]

The gist of the present invention to solve the problem is as follows.

The premise of this invention is that the absorbent body has a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber interposed between the two sheets. Is a disposable diaper provided with a concave portion for use.

Another feature of the present invention is that, in the diaper to be used, a transparent diaper is used as the topsheet, and the shape and color of the bonding area provided between the absorber and the topsheet are provided. , And the density of the color between the concave portion and the portion other than the concave portion so as to be visible from the side of the top sheet, so that the concave portion can be easily identified.

[0008]

In the diaper according to the present invention, a difference is made between the concave portion and the other portion in any one of the shape, type of color, and color density of the bonding area which can be seen through from the top sheet side. The recess can be easily identified by the difference.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Details of the diaper according to the present invention will be described below with reference to the accompanying drawings.

FIGS. 1 and 2 are a partially cutaway perspective view of a diaper 1 according to the present invention and a partial sectional view taken along line 2-2. The diaper 1 is formed by covering a see-through liquid-permeable top sheet 3, a liquid-impermeable back sheet 4, and an absorbing member 5 interposed between these two sheets 3, 4 with a liquid-permeable inner sheet member 6. It is made of an absorbent body 7, and a thread rubber 11 is arranged on the left and right leg side edges, and a thread rubber 14 is arranged on the rear body trunk edge, and each has elasticity. Tape fasteners 15 are attached to both side edges of the rear body. The outer surfaces of the front and back sheets 3 and 4 are tightly joined.

In the diaper 1, a recess 20 for receiving stool is provided in a peripheral area where the anus is located. The concave portion 20 has a side wall 21 and a bottom portion 22 formed by shaping the absorbing member 5. The inner sheet member 6 for preventing the absorbing member 5 from deforming conforms to the shape of the concave portion 20. Is coated. The top sheet 3 also follows the shape of the recess 20 and covers the absorbing member 5 from above the inner sheet member 6. The surface sheet and the inner sheet are intermittently bonded to each other, and there is a conventional technique for preventing the absorbent body from moving relative to the front and back sheets.
The top sheet 3 and the inner sheet member 6 are joined at the bottom 22 at a plurality of joining areas 23 made of hot melt adhesive,
Other parts except the recess 20 are joined by a plurality of joining areas 24. The area of the bonding area 23 is larger than that of the bonding area 24, preferably 2 to 50 times, and the adhesive is appropriately colored so that it is easy to see through from the top of the topsheet 2. The topsheet 2 has a property that does not hinder such see-through, for example, a sheet whose ground color is different from the color of the adhesive, but is generally a commonly used white nonwoven fabric or plastic film. Can achieve that purpose.

In the diaper 1 configured as described above, the joint areas 23 and 24 which can be seen through the topsheet 4 have different sizes (areas), so that the recess 20 can be easily identified.
Further, in order to facilitate the identification, it is possible to make a difference between the joining areas 23 and 24 according to the type and density of the color, and to make a difference using a figure that is interesting to infants. The joining areas 23 and 24 to be seen through may be the joining areas provided between the absorbing member 5 and the topsheet 3, for example, those joining the absorbing member 5 and the inner sheet member 6. There may be. The recess 20 can be identified by printing an appropriate portion of the topsheet 3 for identification, but in that case, alignment between the printed portion and the recess 20 is indispensable. In this diaper 1,
There is an advantage that such alignment work is not required.

In the diaper 1, a nonwoven fabric or a perforated plastic film is used for the top sheet 3, a plastic film is used for the back sheet 4, pulverized pulp or a mixture of pulverized pulp and a superabsorbent polymer is used for the absorbing member 5, an inner sheet member 6 is used.
For example, a tissue paper or a net-like sheet can be used. For the joining to form the joining regions 23 and 24, a general adhesive or pressure-sensitive adhesive, a heat sealing technique, or the like can be used in addition to the hot melt adhesive.

[0014]

The diaper according to the invention makes it easy to identify the stool receiving recess. Also, there is no hassle in matching the recess to the anus when the diaper is worn.
