Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to absorbent articles, and particularly to absorbent articles such as disposable diapers for adults.

[Conventional technology]

In conventional absorbent articles for infants, adults, incontinent persons, or menstrual use (hereinafter referred to as "disposable diapers"), absorbent or A configuration in which the flap is folded back or a configuration in which a stretchable elastic member is provided above the flap are known.

Among them, folded diapers are a typical configuration of disposable diapers because they can be manufactured and processed relatively easily. No. Publication, JP-A-50-16
1347, JP 51-46245, JP 5184041, and JP 57-210004
There are some things described in the No. 1 gazette, etc. The disposable diapers described in each of these publications are so-called box pleat type diapers that have folded parts on both longitudinal edges to form pockets. This is intended to improve the absorbency, retention and sealing properties of the product.

[Problem to be solved by the invention]

However, conventional box pleat type disposable diapers are structured so that the folded absorbent core is finted around the legs, so body fluids and other excreta absorbed in the absorbent core in that area spill over onto the surface. There was a problem that the bedding, etc. would get wet and the excrement would leak, causing discomfort. In addition, these disposable diapers have a sealing mechanism that is formed by folding back the absorbent body, so the sealing mechanism has poor flexibility and is difficult to fit the wearer's body shape. The problem was that it was difficult to follow changes in body shape.

On the other hand, with conventional disposable diapers that have folded side flaps, the pockets are flexible, and the pockets collapse due to body pressure or changes in body shape during activities, and sometimes the side flaps are folded inward, reducing sole properties. There was an issue.

In addition, as other disposable diapers, for example,
There are those described in JP-A No. 8-65002, JP-A-62-199802, and JP-A-62-199806. The disposable diapers described in each of these publications have side flaps on both longitudinal edges, and
A pocket is formed by providing a folded portion on the side flap, and, like those described in the above-mentioned publications, both are designed to improve the absorption, retention, and sealing properties of excrement.

However, although the above-mentioned configuration in which the side flaps are provided with folded parts to form pockets is excellent in retaining excrement, the wearer's ventral part is formed flat, so There is a problem that the fit is poor.

That is, disposable diapers generally do not distinguish between men's and women's diapers, and as a result, there is a problem in that a sufficient fit cannot be obtained for men due to the need for male diapers.

On the other hand, it is conceivable to manufacture products for women and men separately, but in such a case, there is a problem of high costs.

Therefore, an object of the present invention is to provide an absorbent article that has a high fit and is inexpensive to manufacture.

[Means to solve the problem]

The present invention includes a main body having a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body disposed between these two sheets, and the main body is attached to the wearer's ventral side when worn. In an absorbent article that forms a ventral part where the ventral part is located, and a dorsal part which is located on the wearer's back when worn, the ventral part has both sides extending outward in the width direction, and the absorptive article has a ventral part located on the wearer's back side when worn. A pair of first folded parts each having a first folded part which is folded back so as to overlap the folded part on the side, and a second folded part which is further folded so that both sides of the folded part are further folded back toward the outside in the width direction. a pair of second folded parts, the pair of second folded parts are located apart from each other on the width direction center side of the abdominal part, and the first folded part has a second folded part on the folded part. The above object has been achieved by providing an absorbent article characterized in that it is fixed by the fixing means of No. 1.

(Function) According to the above-mentioned absorbent article, a conventional so-called flat type absorbent article is used, and both sides of the ventral side portion thereof are folded back to form a pair of first and second folded portions. By simply fixing the folded part 1 to the folded part on the center side in the width direction, an absorbent article suitable for men's parts can be easily manufactured.

Furthermore, since the structure is such that a conventional so-called flat type absorbent article is simply folded back and fixed, the absorbent article for men can be manufactured at low cost.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The absorbent article of the present invention will be explained using an adult disposable diaper as an example.

As shown in FIG. 1, a disposable diaper 1 includes a liquid-permeable top sheet 2 forming the side that contacts the wearer's skin, a liquid-impermeable bank sheet 3 corresponding to the top sheet 2, and a liquid-impermeable bank sheet 3 corresponding to the top sheet 2. The main body 5 includes an absorbent body 4 arranged between the sheets 2 and 3 to absorb excrement.

The top sheet 2 is preferably a liquid-permeable sheet that allows excrement to pass through to the absorbent body 4 and has a feel similar to underwear. Examples of such liquid-permeable sheets include woven fabrics, non-woven fabrics, porous fabrics, etc. Films and the like are preferred. In addition, repellency can be achieved by applying a hydrophobic compound such as a silicone oil or paraffin wax to the periphery of the top sheet 2, or by applying a hydrophilic compound such as an alkyl phosphate ester in advance and washing the periphery with warm water. By applying water treatment, it is possible to prevent leakage due to seepage of urine, etc. at the peripheral edge.

The hack sheet 3 is a vapor-permeable, liquid-impermeable sheet that is made by adding a filler to a thermoplastic resin and stretching it, and a material that has a feel similar to underwear, such as a composite material of a film and a nonwoven fabric, or a film. A composite material of woven fabric and other materials is used.

The absorbent body 4 is preferably one mainly composed of a defibrated valve and a water-absorbing high-molecular polymer, and also preferably a mixture of a thermoplastic resin, cellulose fiber, and a water-absorbing high-molecular polymer that is heat-treated. The high-molecular water-absorbing polymer may exist in any of the upper phase, middle phase, and lower phase, and may be mixed with the valve. It is preferable to use a particulate material that has a retention property capable of absorbing and retaining water and has the property of gelling. Examples of such a high molecular weight water-absorbing polymer include starch-acrylic acid (salt) graft copolymer, starch-acrylic acid (salt) graft copolymer, starch- Saponified product of acrylonitrile copolymer,
A crosslinked product of sodium carboxymethyl cellulose, an acrylic acid (salt) polymer, etc. are preferred.The shape is preferably an hourglass shape that matches the body shape of the wearer, but it may be rectangular.

The main body 5 is formed into a substantially H-shape with a constriction at the center in the longitudinal direction (vertical direction in the figure), and a crotch section 6 is formed in the constricted part.
A ventral part 7, which is located on the ventral side of the wearer when worn, is formed in one wide part. On the other wide part,
A back side part 8 located on the back side of the wearer is formed.

Waist flaps 9 are provided at both ends of the main body 2 in the longitudinal direction of the abdominal part 7 and the back part 8, respectively, and extend outward from the absorbent body 4.
, IO are formed, and a pair of left and right side flaps 11, 12 are formed outwardly in the width direction of the absorbent body 4.

Further, leg portions 13 are formed on the left and right sides of the crotch portion 6 outward in the width direction.

In the dorsal side part 8, a pair of left and right side flaps 12 and 12 are each provided with a tape fastener 19, and when worn, the tape fastener 19 is attached to the side flap 11 of the ventral part.
．． 11.

In the abdominal portion 7, folds are formed on both side portions 14a and 14b (including the side flaps 11) extending outward in the width direction. That is, both sides 14a, 14 of the abdominal part 7
b has a first folded portion 15a, 15b folded back so as to overlap the folded portions 7a, 7b.
folded parts 16a, 16b and first folded part 1
6a.

Second folded part 1 folded back so as to overlap 16b
Second folded portions 18a, 18b having 7a, 17b
is formed. The first folded portions 16a, 16b are folded back toward the center in the width direction, and the first folded portions 16a, 16b are substantially on extension lines of both side edges of the crotch portion 6.

Further, second folded portions 18a and 18b are formed in the center direction in the width direction of each of the second folded portions 18a and 18b so as to be spaced apart from each other by folding back the side portions 14a and 14b outward again.

Therefore, the first folded portions 16a, 16b and the second folded portions 18a, 18b form the both sides 1 of the abdominal portion 7.
4a and 14b are partially overlapped at the folded portions 7a and 7b on the center side in the width direction, and the side flaps 11 and 11 on the ventral side are respectively extended to the outside.

As a result, as shown in FIG. 1, when the disposable diaper according to this embodiment is unfolded, the width of the abdominal part 7 is shorter than the width of the blue side part 8.

Further, as shown in FIG. 2, the first folded portion 15a
, 15b is a hot melt 20 as a first fixing means.
a, 20b, the second folded portions 18a, 18, respectively.
It is attached to the folded portions 7a and 7b in the vicinity of b. Thereby, the folded state of the first folded portions 16a, 16b is reliably fixed.

The second folded portions 17a, 17b are adhered onto the first folded portions 15a, 15b in the vicinity of the I-th folded portions 16a, 16b using hot melts 21a, 21b as second fixing means. . This allows the second
The folded state of the folded parts 18a and 18b is reliably fixed.

By forming the first and second folded portions 16a, 16b, 18a, and 18b on the ventral side portion 7 of the main body, the diaper main body 5 is shaped to suit the male's specific area, and has an excellent fit. Diapers can be provided.

In addition, although FIG. 3 shows a conventional disposable diaper 22 for adults, in other words, the disposable diaper 22 shown in FIG. 3 is an intermediate product of this embodiment, and this conventional disposable diaper 22, the disposable diaper 1 according to this embodiment is manufactured by folding and adhering in the steps described above.

That is, the conventional adult disposable diaper 22 shown in FIG.
By folding back and gluing the abdominal part 7 as described above, the male disposable diaper of this example is manufactured.

The present invention is not limited to the one embodiment described above (and can be modified in various ways without departing from the gist of the invention.

For example, the first and second fixing means are not limited to using hot melt, but may also be ultrasonic, adhesive, or the like.

Further, as shown in FIG. 4, the first and second fixing means may be a so-called target tape 25 provided on the ventral side of the backsheet 3, i.e., the backsheet 3 on the back side of the diaper. A target tape 25 is provided on the second folded portion 16a, 1 by this target tape 25.
6b is fixed with adhesive.

In the above-described embodiment, the first or second folded portion is fixed at one point each, but the same effect can be obtained even if the first or second folded portion is bonded at multiple points or in a line. can.

Regarding the fixing of these folded parts, if the fixed part is further provided closer to the edge, the pocket will become deeper and the leakage prevention effect will be improved.

Furthermore, in the above embodiment, the first or second folded portions are parallel, but in order to further prevent leakage from the dorsal portion, the folded portions are parallel to each other as shown in FIGS. 5 and 6rM. The interval H between the first or second folded portions may be formed to be gradually narrower as it extends outward in the longitudinal direction of the absorbent article. In the modified example shown in FIG. In the modified example shown in FIG. 6, the first and second folded portions are folded back diagonally.

[Effects of the Invention] The absorbent article of the present invention has high fitting properties and is inexpensive to manufacture.
