Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid absorbent article worn by a person in underwear, such as a sanitary napkin or an incontinence pad, on both sides of a wing (also referred to as a flap).
Are characterized by having high leakage prevention performance and good usability.

[0002]

2. Description of the Related Art Conventionally, liquid absorbent articles such as sanitary napkins and incontinence pads are generally long in the front-rear direction.
A liquid-permeable top sheet, a liquid-impermeable back sheet,
It is known that a main part is formed by a liquid absorbing / holding absorbent body interposed between the main body and a joining part for preventing slippage to the inner surface of the underwear on the back side of the back sheet (for example, see Japanese Patent No. 256097).
No. 855011).

[0003] Further, a device having wing portions on both sides of a main body is also already known (for example, Japanese Patent No. 2587072).
Gazette, Japanese Patent No. 2997470, and Jitsuhei 8-78
No. 51, Utility Model Registration No. 2559757, Utility Model Registration No. 2570249, etc.). The wing part here is at the position of the crotch part of the underwear worn, by folding it down along the underwear both side edges and joining it,
This prevents the liquid absorbent article from moving.

[0004]

However, each of the above liquid absorbent articles has only a pair of wings on both sides of the main body. Therefore, even when the absorbent article is intended to be firmly fixed to the underwear at the time of wearing with the joint for preventing displacement, the absorbent article may move depending on the movement or posture of the body, and between the wing part and the underwear side edge. A gap was formed, and menstrual blood and urine flowed into the gap, making it easy to leak after a lateral leak.

[0005] In view of the above, there has been proposed an improvement in which the wing portion is provided, and two front and rear wing portions are formed on both sides of the main portion (for example, Japanese Patent No. 270354).
No. 1, JP-A-11-501857, etc.).

However, even if the front and rear wing portions are provided on both sides of the main body portion, the rear wing portion only has to be put in the underwear, has almost no action of preventing the displacement, and the absorber has It is only provided in the main body and not provided in each wing. In this case, when the body is lying down at night or the like, or when the body is moved, the liquid absorbent article shifts in the underwear, and menstrual blood, urine, etc. are likely to leak laterally or backward. In addition, there is a case where it leaks to the side by oozing on the surface of the main body portion, or moves rearward along a valley of the crotch to leak laterally and backward.

[0007] For this reason, it is not uncommon for underwear for preventing leakage to be worn, but sweat tends to occur on the buttocks and stuffiness tends to occur. However, there has been no liquid absorbent article capable of absorbing the sweat.

An object of the present invention is to eliminate the disadvantages and problems of the above-mentioned conventional liquid absorbent article having a wing portion. That is, an object of the present invention is to provide a liquid-absorbent article with a wing portion, which has high leakage prevention properties such as side leakage and back leakage, and is also capable of absorbing perspiration in the buttocks and excellent in usability.

[0009]

The liquid-absorbent article with wings according to the present invention has a main body 1 elongated in the front-rear direction and wings 2 on both sides, and a liquid-permeable topsheet 3 is provided. A liquid absorbing / holding absorber 5 is interposed between the liquid-impermeable back sheet 4 and a joint 6 for preventing slippage with an undergarment 7 formed on the back side of the back sheet 4. 1
The main absorber 5a is installed from the front to the rear, and the wings 2 are provided at least on both sides of the main body 1.
Front wing 2a corresponding to the lower front part of the body
A wide rear-side wing portion 2b corresponding to the lower rear portion and having a wide sub-absorber 5b inside the rear-side wing portion 2b in each side wing portion; The shift wing portion 2b is formed so that the both sides thereof are folded back to the outer surface of the underwear 7 and the joint portion 6c for preventing slippage is formed on the back side of the back sheet 4.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Here, the liquid-absorbent article is, for example, a sanitary napkin or an incontinence pad as described above.
It refers to a material worn by a person in underwear 7 such as shorts to absorb and store menstrual blood, urine, and the like.

In the above construction, the main body 1 is elongated in the front-rear direction from the lower front part to the lower rear part of the body when worn, and has the wing parts 2 on both sides. The sheet 4 has substantially the same shape, and the outer peripheral portion is integrated by heat sealing or bonding with an adhesive or the like. Although there are various thicknesses of the main body portion 1, it seems that a thinner one having a thickness of 3 mm or less has recently been preferred.

The topsheet 3 is liquid-permeable, allows menstrual blood, urine, etc. to permeate quickly, is absorbed and stored by the inner absorber 5, and does not cause discomfort to the contacted skin. As is known, it is preferable to use, for example, a woven or nonwoven fabric of natural or synthetic fibers, a porous synthetic resin film, a net-like synthetic resin foam, or another liquid-permeable film.

The back sheet 4 is liquid-impermeable and prevents menstrual blood and urine absorbed and stored in the absorber 5 from leaking and leaking and adhering to the skin and underwear. As the material, it is preferable to use, for example, a polyolefin film, a polyethylene film, or another liquid-impermeable synthetic resin film as is known. At an appropriate place on the back side of the back sheet 4, for example, an adhesive tape or another joint is provided as a joint 6 for preventing displacement with the underwear 7.

The absorber 5 is composed of a main absorber 5a and a sub absorber 5b. The main absorber 5 a is long in the front-rear direction, has a length from a position corresponding to the lower front part of the body to a position corresponding to the lower rear part, and is provided inside the main body 1. The shape and size of the main absorber 5a are
The storage capacity is appropriate and the usability is good. For example, the length is about 200 to 350 mm and the width is 60 to 8 mm.
It is good to keep it at about 0 mm. As will be described later, the sub-absorber 5b is provided inside at least the front wing portion 2a to the rear wing portion 2b.

The main and sub-absorbers 5a and 5b absorb and retain menstrual blood, urine and the like transmitted through the topsheet 3, and are made of a known material such as creped cellulose wadding. , Air felt (finely ground wood pulp), absorbent synthetic resin foam, tissue paper layer, absorbent gelling material, or a combination thereof as appropriate.

The wing 2 is formed by expanding the top sheet 3 and the back sheet 4 to both sides of the main body 1 and heat-sealing or bonding the outer periphery thereof. And a rear-side wing portion 2b. Here, the front-side wing portion 2a is provided on a side corresponding to a position closer to the lower front portion of the body, and the rear-side wing portion 2b is provided beside a position corresponding to the lower rear portion of the body. The side wing portion 2b has a large width (see FIGS. 1, 3, 5, 7, and 8). The maximum width is preferably, for example, about 40 to 70 mm on one side.

The sub-absorber 5b is provided inside the front and rear wing portions 2a and 2b on both sides as described above, but the sub-absorber 5b may be provided separately on both sides (for example, 3 and 5 described above). However, it may be provided on the lower surface of the main absorber 2a in the main body 1 as an integral body including both sides (for example, see FIG. 1 described above). The shape, size, and the like are designed so that the absorption and storage capacity is appropriate and the usability is good.

It is desirable that a slit 10 is formed between the front-side wing portion 2a and the rear-side wing portion 2b to separate the front and rear wings (for example, FIG. 1).
-See FIG. 3), one or more intermediate wings 2c between the front wing 2a and the rear wing 2b.
(For example, see FIG. 5 described above). When a plurality of intermediate wings 2c are provided, the shape becomes almost continuous.

The leak-proof sheet 8 is provided so as to surround the lower surface and the outer side of the main absorber 5a (for example, FIG. 1).
3 and FIG. 5), it is desirable to provide menstrual blood, urine, and the like absorbed and stored in the main absorber 5a in order to prevent outflow and leakage. The material may be the same as that of the back sheet 4, and for example, a polyolefin film, a polyethylene film, or another liquid-impermeable synthetic resin film may be used.

The folding portion 9 of the rearward wing portion 2b is formed by bending the lateral portion of the rearward wing portion 2b downward so that it can be folded from the side edge of the underwear 7 to the outer surface. Although it is better not to have the sub-absorber 5b inside this portion, a displacement preventing joint 6c is also formed on the back surface of the back sheet 4 corresponding to the folded portion 9.

It is desirable to form partition walls 11 on both sides of the main absorber 5a of the main body 1 in order to prevent the main absorber 5a from moving laterally.
Although it is desirable to use the same degree as that shown in FIGS.
(See FIG. 1) at least so as to correspond to the rear wing portion 2b. This is desirably formed by pressing the top sheet 3 and joining it to the surface of the sub-absorber 5b (for example, see FIG. 2) or joining it to the back sheet 4 (for example, see FIGS. 4 and 6). Either an adhesive or a heat seal may be used. Reference numeral 12 denotes a groove, which is a concave stripe formed by the formation of the partition wall 11.

In each of the wings 2a and 2b,
Separate leak-proof sheet 1 surrounding outer side of sub-absorber 5b
3 may be provided (for example, see FIG. 6 described above), or at a substantially intermediate position in the front-rear direction of the main absorber 5a to prevent menstrual blood, urine, and the like from moving from the front side to the rear side. Alternatively, the projections 14 may be formed corresponding to the valleys of the crotch of the body (for example, see FIG. 1 described above).

Although not shown in the drawings, for example, a three-dimensional fit gather type may be combined.
A fragrance, a deodorant, or an agent that absorbs sweat may be provided in the turn-back portion 9.

The method for producing the present liquid absorbent article may be, for example, as follows. Main part 1 longer in front and rear direction
A flat surface sheet 3 corresponding to the front and rear wing portions 2a and 2b is prepared on both sides thereof, and the front surface is reversed on a template having a recess corresponding to the main portion 1. Then, if necessary, the lower surface and both sides of the main absorbent body 5a are surrounded by a leak-proof sheet 8, and if necessary, a convex portion 14 is formed on the surface. 3 Place it upside down.

Thereafter, the sub-absorber 5b is placed on the top sheet 3 corresponding to the front / rear wing sections 2a, 2b, and the back sheet 5 is placed on the top sheet 3 so as to be placed between the top sheet 3 and the top sheet 3. The outer peripheral portion is joined by heat sealing and integrated. At this time, on both sides of the main absorber 5a surrounded by the leak-proof sheet 8,
The topsheet 3 is linearly transferred to the sub-absorber 5b (see FIG.
(See, for example, FIGS. 4 and 6), and the partition wall 11 is formed. Next, an adhesive sheet is attached to an appropriate position of the back sheet 5 to form the joint portions 6a, 6b, 6c for preventing slippage. What you have just done is to reverse the front and back. This manufacturing method is an example, and is not limited to this.

The use state of the liquid absorbent article having a wing portion of the present invention is as follows. B) First, when wearing this liquid absorbent article, the user, in the same way as this kind of conventional type, wears the underwear 7 such as shorts and pants from the lower forward part to the lower rear part of the body. (See, for example, FIG. 7).

At the time of wearing, the main part 1 of the liquid absorbent article
The inner-side portions of the wings 2a, 2b and the like come to the inside of the underwear 7, and the outer-side portions of the wings 2a, 2b and the like on both sides come outside the both side edges of the underwear 7. Therefore,
The joint 6a for preventing slippage on the back side of the back sheet 4 of the portion inside the underwear 7 is joined to the inner surface of the underwear 7, and both side portions of the underwear 7 protruding outward are folded back to the outside of the underwear 7, respectively. (4) The joint portions 6b and 6c for preventing slippage on the back side are joined (for example, see FIGS. 7, 8, and 9).

As described above, in the present liquid absorbent article, the main part 1
In addition to the rear-side joint 6a and the front-side wings 2a on both sides, and the rear-side joint 6b on both sides, the rear-side wings 9 on both sides.
The joining portion 6c for preventing the displacement of the folded portion 9 is also joined to the outer surface of the underwear 7. Therefore, the present liquid absorbent article and the underwear 7 are securely joined, and even when the wearer takes various postures or moves his / her body, the present liquid absorbent article is positioned within the underwear 7. Is no longer moving.

If the slit 10 is formed between the front wing portion 2a and the rear wing portion 2b, the wings 2a and 2b are independent, so that each of them is folded downward to underwear. 7) It can be easily applied to the outer surface, each bonding state is good, and it is difficult for the wearer to give a feeling of foreign matter when worn.

Further, if the partition walls 11 are formed on both sides of the main absorbent body 5a as described above, the main absorbent body 5a is prevented from laterally moving in the main body 1, so that the wearer can use various kinds of materials. Even when the posture is taken or the body is moved, the main absorber 3a itself does not shift in the main body 1 and can be worn with confidence.

B) When the present liquid-absorbent article is worn as described above, menstrual blood, urine, etc., which have come out of the body, quickly penetrate through the liquid-permeable topsheet 3 in contact with the skin, and 1 is sufficiently absorbed and stored by the main absorber 5a. This does not cause discomfort to the skin, and the liquid-impermeable back sheet 4 prevents menstrual blood and urine from penetrating to the back side and does not stain the underwear 7.

In the present liquid absorbent article, a wide rear wing portion 2b is formed on both sides of the main body portion 1 corresponding to the lower and rear portions of the body, and at least the front wing portion 2a and the rear wing portion are formed. The sub-absorber 3b is mounted on the part 2b.

For this reason, when menstrual blood, urine or the like moves laterally or rearward due to bleeding into the topsheet 3 or the like, a gap is generated between the wings 2a and 2b and the side edge of the underwear 7. ,
Even when menstrual blood or urine leaks there, the sub-absorber 5b in both wings 2a and 2b absorbs and stores it, so that side leakage and back leakage are also prevented, and 7 is not stained.

Further, since the sub-absorber 5b in the wing portion 2b on the rear side is wide, even if, for example, wearing underwear for preventing leakage makes it easy to sweat and sweat on the buttocks, this back side can be used. The wide sub-absorber 5b in the wing portion 2b absorbs sweat. Therefore, it is gentle on the skin, and the wearer can use it comfortably in this aspect as well.

In addition, if the leak absorbing sheet 8 is provided in the present liquid absorbent article so as to surround the lower surface and the outer portion of the main absorbent body 5a, the menstrual blood and urine absorbed and stored by the main absorbent body 5a can also be provided. Is prevented from leaking or leaking downward or to the side, so that there is no side leakage or back leakage, and the liquid absorption / preservation performance of the sub-absorbers 5b on both sides is not hindered.

In addition, in the case where the partition walls 11 are formed on both sides of the main absorber 5a as described above, since both sides are partitioned by the partition walls 11, the partition walls 11 are absorbed and stored in the main absorber 5a. Blood and urine are prevented from leaking and leaking to the side, and lateral leakage and the like are further prevented.

The front and rear side wing portions 2a, 2b
If a separate leak-proof sheet 13 is provided so as to surround the outside of the sub-absorber 5b (see, for example, FIG. 6 described above), liquid leakage from the sub-absorber 5b is prevented. In addition, if the convex portion 14 corresponding to the valley of the crotch portion of the body is formed at a substantially middle position in the front-rear direction of the main absorber 5a, menstrual blood, urine, and the like are less likely to move from the front to the rear. , Leakage is further prevented.

[0061]

As is apparent from the above, the liquid-absorbent article with wings according to the present invention has higher leakage prevention properties such as side leakage and back leakage as compared with the conventional liquid-absorbing article of this type, and also has a good effect on the buttocks. It can absorb sweat and is excellent in usability.

That is, in a conventional liquid absorbent article of this type, which has a pair of wings on both sides of the main body, the pair of wings is used to attach to underwear. The sexual article may move in the underwear, and it was easy for side leakage and back leakage. In the case of having two pairs of wing parts on both sides of the main body part, the rear wing part is put in the underwear, there is almost no displacement movement preventing action, and the absorber is only the main body part and is not provided in the wing part As a result, there were also side leaks and back leaks. There is also underwear for preventing leakage, but when worn, sweating tends to occur on the buttocks, often causing stuffiness.

On the other hand, in the liquid-absorbent article with wings of the present invention, menstrual blood, urine, etc., which have come out of the body, quickly penetrate through the liquid-permeable top sheet in contact with the skin, and the main absorbent in the main body portion. Is not absorbed into the skin, does not cause discomfort to the skin, and does not penetrate to the back side by the liquid-impermeable back sheet, as in the conventional case.

In addition, in the present liquid absorbent article, a) the main body portion is joined to the inner surface of the underwear when it is worn, and the front side wing portion is joined not only to the outer front surface of the underwear but also to the rear side wing. A portion is formed, and a portion closer to the side is a folded portion, and a joining portion for preventing displacement is formed on the back side of the back sheet, which is also joined to the outer surface of the underwear.

Therefore, when the present liquid absorbent article is worn,
Even when the wearer takes various postures or moves his / her body, the position can be prevented from shifting with the underwear, and side leakage, back leakage, and the like can be eliminated.

(B) In the present liquid absorbent article, not only the main absorber is provided in the main portion, but also the sub-absorbers are provided in the front wing portion and the rear wing portion on both sides.

As a result, menstrual blood, urine, etc. may move laterally or rearward due to bleeding on the topsheet, or a gap may be formed between both wings and the side edges of the underwear, causing menstrual blood, urine, etc. to leak. In such a case, the sub-absorbers in the front-side wing portion and the rear-side wing portion can absorb and store the same, and in this respect, side leakage and rear leakage can be prevented.

(C) In the present liquid-absorbent article, the sub-absorber in the wing portion on the rear side is formed wide. Therefore, for example, when wearing underwear for leakage prevention, even if it sweats on the buttocks and becomes stuffy, the wide sub-absorber in the rear wing part can absorb sweat, and it is gentle on the skin and worn Can be used comfortably.

D) In the present liquid absorbent article, in which a leak-proof sheet is provided so as to surround the lower surface and the outer part of the main absorbent, menstrual blood and urine absorbed and stored in the main absorbent are mainly absorbed. Leakage and leakage from the body downward and to the side can be prevented, side leakage and back leakage can be eliminated from this surface, and the liquid absorption performance of the sub-absorber is not hindered.

(E) In the present liquid-absorbent article, in which a slit is formed between the front-side wing portion and the rear-side wing portion, the front and rear-side wing portions are independent. Can be easily folded and joined to the outer surface of the underwear. For this reason, the joined state is hard to be detached, and it is difficult for the wearer to feel a foreign body at the crotch and buttocks.

(F) In the present liquid absorbent article, in which the partition walls are formed on both sides of the main absorbent, the main absorbent can be prevented from laterally moving in the main part. Therefore, even when the wearer takes various postures or moves his body, it is possible to prevent the main absorber from being displaced, and from this point, there is no side leakage, and the wearer wears with confidence. be able to.

G) In the case where partition walls are formed on both sides of the main absorber as described above, menstrual blood, urine, and the like absorbed and stored by the main absorber flow out and leak to the side also by the partition walls. Is prevented, lateral leakage and the like are further prevented.

(H) In the front / rear side wings,
When a separate leak-proof sheet is provided so as to surround the outside of the sub-absorber, leakage of menstrual blood, urine, etc. absorbed and stored by the sub-absorber is prevented.
