Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable diaper in general that can easily treat loose stools and the like.

[0002]

2. Description of the Related Art Measures have been taken such as providing recesses or pockets in an absorbent body of a diaper for the purpose of storing urine and feces separately and facilitating leakage and post-treatment. When the fluidity of the stool is high as described above, there are cases where the stool does not fit properly in these storage locations depending on the living activity of the wearer and the body orientation.

Disposable diapers have been developed which have improved absorbability for urine and loose stools by using a so-called "skin-contacting sheet" obtained by opening the surface sheet of the diaper.
No one with excellent absorbency has come out. As a result, the skin is soiled due to contact with the excrement and reversion, and there is a problem in hygiene.

Further, in order to manufacture a diaper having an opening surface sheet and an absorbent pocket, it is necessary to introduce a considerable amount of equipment, so that there is no cost advantage, and a notched portion is required for the opening treatment. It becomes garbage and it gets mixed in the process,
We have problems such as waste.

[0005]

The present invention solves these problems, and excretions such as loose stools and urine are collected in the lower space of the surface sheet without liquid flowing through the surface sheet, and The purpose is to prevent the backflow of accumulated excretion and to keep the skin hygienic.

[0006]

The present invention provides an absorbent article having an absorbent body between a surface sheet and a leak-proof sheet, wherein a large number of valve-shaped half openings are arranged on the surface sheet. Regarding the product.

Further, according to the present invention, the valve-shaped half openings are left without cutting out a part thereof, respectively, so that they open to the lower layer under the weight of soft stool, but do not open to the backflow of stool from the lower layer. Related to absorbent products. Further, the present invention relates to an absorbent product in which the size of the valve-shaped half opening is set in the range of diameter 3.0 mm to 20.0 mm. The size of the half opening is the diameter
If it is less than 3.0 mm, the valve will not open sufficiently, and if it is greater than 20.0 mm, the stool supplement effect will not be obtained. Further, the present invention is a top sheet GMT (geometrical mean of longitudinal and transverse tensile strength gf / 25 mm).
Relates to absorbent products having a range of 500 to 900 gf.

Further, the present invention relates to an absorbent product in which a carrier sheet or a transfer sheet made of bulky non-woven fabric or pulp paper or easily deformable cotton-like fiber or the like is interposed between the topsheet and the absorbent. Further, the present invention relates to an absorbent product in which an elastic member is provided at an end portion in the longitudinal direction of the topsheet so that the topsheet is joined to the absorber in the lower layer with a space in the longitudinal direction or the width direction. Further, the present invention relates to an absorbent product in which the valve-shaped half-opening, which is left without cutting out a part thereof, is on the back side of the absorbent body and opens and closes on the ventral side, or conversely is on the ventral side and opens and closes on the back side. .

Further, the present invention is 2 / from the ventral side of the top sheet.
The present invention relates to an absorbent product having a valve-shaped half opening that opens and closes on the ventral side up to 3 and a valve-shaped half opening that opens and closes on the back side up to 1/3. In the present invention, the valve-shaped half opening is arcuate,
The present invention relates to an absorbent product having a V-shape, a U-shape or other regular or irregular shape. Further, the present invention relates to an absorbent product having a structure that secures a space in the longitudinal direction between the topsheet and the lower absorbent body when the absorbent product is worn.

The material of the surface sheet is not particularly limited, but thermal bond non-woven fabric such as point bond or air through is suitable in terms of touch. The shape of the valve-like half-opening can be appropriately selected as long as it does not interfere with the feel of the skin and the passage of excretions such as loose feces and urine. Further, the size of the valve-shaped half-opening is appropriately determined from the touch and the excretion of excrement.

The valve-shaped half-opening allows the half-opening to be opened due to the weight of loose stool during the defecation so that the soft stool can be stored in the lower space of the surface sheet, and the excrement accumulated in the lower space of the surface sheet is worn. Do not open the half-opening to prevent backflow of stool. For that purpose, it was found that the GMT is preferably set to 500 to 900 gf, and the half-opening functions well as a valve.

Further, in order to supplement absorption of feces and urine by the absorber and to reduce or prevent discomfort caused by the absorbent material popping out from the valve-shaped half-opening, the surface sheet provided with the half-opening and the absorption It is preferable to interpose a carrier sheet or a transfer sheet made of bulky non-woven fabric or pulp paper, or easily deformable cotton-like fibers or the like with the body. Further, in order to secure a space between the non-woven fabric top sheet and the absorbent body, it is desirable that the top sheet is joined to the lower layer sheet with a space in the longitudinal direction or in the width direction. An elastic member may be provided in the.

The present invention is applicable to all disposable diapers (including urine pads, etc.).

[0014]

The present invention will be described below with reference to the embodiments shown in the drawings, but the present invention is not limited thereto.

FIG. 1 shows an example in which the absorbent product of the present invention is applied to a taped diaper, which is a surface sheet (3) having a large number of leak-proof sheets (1) and half openings (2).
And an absorber (4) interposed between the two,
Fastening tapes (5) and (5) for connecting the seat (1) to the ventral side of the seat (1) are attached to both sides of the back of the seat (1). Incidentally, (6) shows leg gathers, and (7) shows three-dimensional gathers.

FIG. 2 shows a main part of the surface sheet (3), in which half openings (2) having a diameter of 3.0 mm to 20.0 mm are arranged at appropriate intervals in the longitudinal and width directions. ing. The half-opening (2) is composed of a part (a) which is not cut away and a large part (b) which is cut out so that the half-opening (2) acts as a valve.

3 to 5 exemplify the shape of the half-opening portion (2). In FIG. 3, most of the cutout portion (b) is an arc shape.
4 (b) shows a V shape, and FIG. 5 (b) shows a U shape.

FIG. 6 illustrates the valve action of the half-opening (2). Soft feces excreted on the half-opening (2) of the surface sheet (3) move downward through the half-opening (2) due to its weight. Open like a valve,
Further, loose feces excreted above the space between the half openings (2) move to the adjacent half openings (2) and then similarly open the half openings (2) downward in a valve shape. Thus, loose stool or the like passes through the through hole (8) formed by opening the half-opening (2) downward in the shape of a valve, and is captured and absorbed by the absorber (4) in the lower layer.

FIG. 7 shows another construction of the diaper,
This is an example in which a transfer sheet (9) is interposed between the topsheet (3) and the absorber (4). The absorption of feces and urine is complemented by the interposition of this sheet (9) and the absorber (4)
It is possible to prevent the material of (3) from jumping out above the through hole (8).

FIG. 8 shows a state when the absorbent product of the present invention is worn, and is a longitudinal direction from the abdominal side on the right side of the drawing to the dorsal side on the left side of the drawing between the surface sheet and the absorbent body along the body. A space is formed. Therefore, when excrement such as loose stools spreads on the top sheet, it pushes the half-opening downward in a valve shape and passes through it, and accumulates in the space below the top sheet, improving the absorbability of the excrement. . Further, with respect to urine, it is possible to run on the surface sheet immediately after urination and to similarly spread the near half opening without causing liquid flow on the surface so that the urine can be absorbed in the lower layer.

[0021]

The effects of the present invention are summarized and listed as follows. (1) When excretions such as loose stools diffuse on the surface sheet,
The absorbability of excrement is improved by pushing the half-opening and passing it and accumulating in the space under the surface sheet. Immediately after urination, it is possible to promptly absorb into the lower layer from the half opening without running on the surface sheet (liquid flow on the surface). (2) The stored excrement does not flow backward even when worn, and the skin can be kept more hygienic. (3) By improving the storage capacity for loose stools, etc., it is hygienic without polluting the surroundings during removal and processing, and is expected to improve workability during installation and removal. (4) There is no generation of chips due to the opening means, and productivity is improved. (5) The opening location and the opening shape can be adjusted according to the wearer's usage situation.
