Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to disposable absorbent articles and, more particularly, to disposable urine absorbent articles for men.

[0002]

2. Description of the Related Art Conventionally, flat sheet diapers have been generally used as men's urine absorbent articles. This flat sheet diaper is a liquid-permeable surface sheet that directly contacts the wearer's body and absorbs urine, a liquid-impermeable sheet that prevents leakage of absorbed urine, and a space between these two sheets. And an absorber containing urine that has been disposed and is absorbed through a liquid permeable topsheet. At the time of use, this flat sheet diaper is attached so as to cover the crotch and front and back of the wearer by using an appropriate attachment member, and incontinence measures are taken.

[0003]

In order to prevent leakage of urine by using such a flat sheet diaper, it is necessary to position the penis in the approximate center of the absorbent body when wearing the diaper. is necessary. If the diaper is worn while the penis is located away from the center of the absorbent body, when the amount of discharged urine is large, the absorbent body will not sufficiently absorb the urine and side leakage will occur. Cause.

However, inside the diaper, the direction of the penis is not fixed in any one of the upper, lower, left and right directions. Furthermore, even if the penis is positioned in the center of the absorbent body when worn, the position of the penis may be displaced inside the diaper due to the exercise of the wearer. Therefore, in the conventional flat sheet diaper,
There was a case where the urine absorption was not performed reliably and the intended purpose of preventing urine leakage could not be achieved.

The present invention has been made in view of the above circumstances, and is a disposable absorbent article having a liquid-permeable surface sheet, a liquid-impermeable sheet, and an absorbent body arranged between these two sheets. An object of the present invention is to provide a disposable absorbent article in which the penis can be reliably stored in an appropriate position inside these disposable absorbent articles, and urine leakage can be reliably prevented.

[0006]

In order to achieve this object, the disposable absorbent article according to the present invention is provided with flap members for holding the penis from both sides inside the disposable absorbent article. Specifically, the disposable absorbent article according to the present invention is provided with a pair of flap members having a base end attached to a liquid-permeable surface sheet and a free end and extending in the longitudinal direction of the absorbent article. And the base end is located on the absorber, and the distance between the base ends of the pair of flap members and the length from the base end to the free end are such that the male penis can be held between the pair of flap members. Is decided.

In a preferred embodiment of the present invention, the pair of flap members are arranged substantially symmetrically spaced about the longitudinal axis of the absorbent article. In a preferred embodiment of the present invention, the distance between the proximal ends of the pair of flap members is 0 .., where D is the diameter of the male penis.
It is set to be 5D or more and 4D or less.

In a preferred embodiment of the invention, the length from the proximal end to the free end of the pair of flap members lies on the liquid permeable topsheet with the free ends oriented toward the longitudinal axis of the absorbent article. The distance between the free ends is set to a length that is less than or equal to the diameter of the male penis. In a preferred embodiment of the present invention, at least one elastic member is attached to the free ends of the pair of flap members.

In a preferred embodiment of the present invention, the elastic member is provided at least in a region which is on the front side when the article is used. Some conventional diapers have elastic members called “three-dimensional gathers” provided along both side edges extending in the longitudinal direction of the diaper. This three-dimensional gather is mainly provided to prevent loose loose stools such as diarrhea from leaking from the side edge of the diaper, and the three-dimensional gathers have a wide space between them.
It cannot hold the penis between those three-dimensional gathers as in the present invention. It is essentially different from the flap member of the present invention.

[0010]

When the present disposable absorbent article is used, the penis is positioned between the flap members which are provided at regular intervals. If the present disposable absorbent article is worn in this state, the penis is held between the flap members, and the penis will surely fit inside the absorbent article. Therefore, the urine discharged from the penis is surely absorbed by the absorbent article and does not leak from the side edge of the absorbent article.

In particular, when the elastic member is attached to the free end of the flap member, the elastic member contracts to form the gathered portion at the free end of the flap member. Since the urine is held at a predetermined position, it is possible to more surely prevent urine from leaking to the outside.

[0012]

1 and 2 show a first embodiment of a disposable absorbent article according to the present invention. The disposable absorbent article 1 is
A liquid-permeable surface sheet 3 made of a material that is in direct contact with the wearer's body and can penetrate body fluids such as urine, a liquid-impermeable sheet 5 made of a material that does not allow liquid to penetrate, and a liquid-permeable surface sheet 3 And an absorbent body 7 that is disposed between the liquid impermeable sheet 5 and absorbs and retains urine and other body fluids that have permeated through the liquid permeable surface sheet 3. The absorbent body 7 has a rectangular shape, and the liquid-permeable surface sheet 3 and the liquid-impermeable sheet 5 both have a larger rectangular shape than the absorbent body 7. And the absorbent body 7 is wrapped inside.

An elastic member 9A extending in the direction of the longitudinal axis Y of the disposable absorbent article 1 is provided in the side margin portion (that is, the outer portion of the absorbent body 7) where the two sheets 3 and 5 are adhered to each other. , 9B are incorporated. The elastic members 9A and 9B are incorporated in an expanded state,
When this article 1 is used, the elastic members 9A and 9B are in a contracted state, forming a so-called gather. For this reason,
The article 1 can be tightly adhered to the wearer in the crotch of the wearer, and leakage of urine from the article 1 in the crotch can be prevented.

The liquid permeable topsheet 3 of the article 1 comprises:
A pair of flap members 11A, 11B having a predetermined width L and extending over the entire length in the longitudinal direction of the article 1 are attached. The flap members 11A and 11B are attached to the liquid permeable topsheet 3 at their base ends 12A, and the other ends are free ends 12B. Base end 12A
Is positioned more outward than the free end 12B in the width direction of the article 1, and the free ends 12B are arranged so as to face each other. Further, the flap members 11A and 11B are attached symmetrically with respect to the longitudinal axis Y of the article 1, and the free ends 12B of the flap members 11A and 11B are located in contact with each other on the longitudinal axis Y.

The base end 12A of each flap member is arranged so as to always be located on the absorber 7. As shown by the arrow K in FIG. 2, the flap members 11A and 11B can swing the free end 12B around the base end 12A, and can be in an upright state. Usually, as shown in FIG. 2, it is in a state of lying on the liquid-permeable surface sheet 3.

Base ends 12A of the flap members 11A and 11B
Are substantially symmetrically attached to each other at a predetermined interval R with the longitudinal axis Y of the article 1 as the center. Assuming that the average diameter of the male penis is D, the predetermined interval R is 0.
5D ≦ R ≦ 4D. If this interval R is too narrow, the penis cannot be held between the flap members 11A and 11B, and conversely, if the interval between the flap members 11A and 11B is too wide, the penis will be between the flap members 11A and 11B. Even if the penis is held, the penis moves toward the end of the absorbent body 7 and the intended purpose of preventing urine leakage cannot be achieved. Therefore, the distance R between the flap members 11A and 11B is preferably 0.5D at the minimum and about 4D at the maximum.

For example, since the average diameter of the penis of men in their 70s to 80s is about 20 mm, the pair of flap members 1
The interval R between 1A and 11B is set to about 10 to 80 mm. If the interval R is set regardless of the age of the wearer, the preferred interval R is 10 mm or more and 100 mm.
It is the following.

Further, it is preferable that the distance R between the base ends is determined not only by the average diameter of the male penis but also by the average length as a parameter. For example, if the penis is long, the flap members 11A, 1
The penis can be stored in 1B. On the contrary, when the penis is short, the flap member 1 is correspondingly
It is preferable that the distance R between 1A and 11B is also small.

As is apparent from FIG. 1, R = 2L
Therefore, if the distance R between the base ends 12A is determined, the width L = R / 2 of the flap members 11A and 11B is also automatically determined. The flap members 11A and 11B may be made of any material regardless of whether they are liquid-permeable or liquid-impermeable.

Free ends 12 of flap members 11A, 11B
Stretchable members 13A and 13B are incorporated in B.
As the elastic members 13A and 13B, any member can be used as long as it has elastic force. For example,
Thread rubber, elastic tape, elastic film, elastic nonwoven fabric, etc. can be used. This elastic member 13A, 1
3B is also incorporated in the free end 12B of the flap members 11A and 11B in a stretched state like the stretchable members 9A and 9B. Therefore, since the elastic members 13A and 13B are contracted when the absorbent article 1 is used, the free ends 12B of the flap members 11A and 11B form gathers.

The expansion ratio of the elastic members 13A and 13B is
Although depending on the material and elastic strength, 100 to 500% is preferable. It is more preferably 150 to 200%. Further, at least one elastic member 13A, 13B is provided for each flap member 11A, 11B according to its elastic strength. The elastic members 13A and 13B are the present article 1
When the article 1 is divided into two with the axis X in the width direction as the center, one of the sides, more specifically, the article 1
It should be provided only on the side located on the front side during use. In this embodiment, as shown in FIG. 1, it is provided only in the upper half of the width direction axis X. As will be described later, since the penis is located in an approximately half region in the longitudinal direction of the present article 1, the elastic members 13A and 13B are placed in the present article 1.
The penis can be sufficiently retained even if it is not installed over the entire length of the.

Free ends 12 of flap members 11A, 11B
The elastic members 13A and 13B are attached to B by, for example, hot melt or adhesive tape. Further, when attaching the elastic members 13A and 13B, as shown in FIG. 3A, the elastic members 13A and 13B may be wound only at the free end 12B,
Alternatively, as shown in FIG. 3B, the flap member 11
A and 11B are doubly overlapped and the elastic member 13A,
You may make it pinch 13B.

As shown in FIGS. 4A and 4B,
It is also possible to attach a plurality of elastic members 13A and 13B. FIG. 5 is a perspective view showing a usage state of the absorbent article 1. When the absorbent article 1 is used, the flap members 11A and 11B are swung around the base ends 12A thereof in the direction of arrow K to move the free end 12B.
Leave 1A and 11B upright. Next, the penis 15 is positioned between the flap members 11A and 11B on the side where the elastic members 13A and 13B are provided. In this state, as shown in FIG. 5, the present article 1 is wound around the wearer's crotch around the front and back of the wearer, and the present absorbent article 1 is attached to the wearer using an adhesive tape or other appropriate fixing means. Fix it.

When the article 1 is worn, as shown in the sectional view of FIG. 6, the penis 15 is provided with the flap members 11A, 1A.
It is held from both sides by 1B. Since the proximal end 12A is always located on the absorbent body 7, the penis 15 is always located on the absorbent body 7, and the urine discharged from the penis 15 is surely absorbed by the absorbent body 7, Does not leak outside.

In particular, the flap member 1 is formed by gathers formed by the contracting action of the elastic members 13A and 13B.
1A and 11B securely hold the penis 15,
Prevention of leakage of urine is promoted. 7 and 8 show a second embodiment of the disposable absorbent article 1 according to the present invention. In this second embodiment, the flap members 11A, 11B are not in contact with each other at their free ends 12B and their free ends 1
It has the same configuration as that of the first embodiment except that 2B is spaced apart by a distance W.

The interval W is set so as to fall within the range of the average diameter of the male penis. This is because when the distance W exceeds the average diameter of the male penis, the pair of flap members 11A and 11B cannot hold the penis from both sides when the present article 1 is worn. It is preferable to use the length of the penis as a factor when determining the distance W. For example, when the penis is long, the distance W can be approximately equal to the average diameter of the penis, but the penis can be held between the flap members. In order to ensure that the free ends of the flap members are accommodated, it is preferable that the interval W be smaller than the average diameter of the penis to narrow the interval between the free ends of the flap members.

Thus, the flap members 11A, 11B
By arranging the flap members 11A and 11B so that the free end 12B of the diaper opens the gap W, the penis is directly inserted into the portion of the gap W without standing the flap members 11A and 11B at the time of wearing, and then, The present article 1 can be worn, and convenience at the time of wearing increases.

9 and 10 show a third embodiment of the disposable absorbent article according to the present invention. The third embodiment has the same configuration as that of the first embodiment except that the flap members 11A and 11B are not in contact with each other at the free ends 12B and overlap each other. The length T of the portion where the flap members 11A and 11B overlap each other is preferably about 50 mm at maximum. Furthermore, in this embodiment,
The width L of the flap member is set so that L ≦ R. This is because if the width L of the flap member is made too long, the length T of the overlapping portion becomes large, making it difficult to wear.

For example, when the distance R between the base ends 12A of the flap members 11A and 11B is set to 60 mm and the width L of the flap members is set to 55 mm, the length T of the overlapping portion is set.
Becomes T = 55 × 2-60 = 50 mm. As in the present embodiment, the flap members 11A, 11
By arranging B so as to overlap each other, the penis can be held so as to be wrapped between both sides of the flap member, so that the tip of the penis from which urine is discharged can be reliably held between the pair of flap members. .

FIG. 11 shows a fourth embodiment of the disposable article according to the present invention. In this embodiment, the elastic member 13
A, 13B side (width direction axis X of the present article 1
In the upper half), the gap W1 between the flap members 11A and 11B is formed to be relatively narrow, and the elastic member 13
On the side where A and 13B are not provided (the lower half of the widthwise axis X of the article 1), the gap W2 between the flap members 11A and 11B is formed relatively wide.

In the absorbent article 1 according to this embodiment, the penis is applied to the side where the elastic members 13A and 13B are provided, and the hip is applied to the side where the elastic members 13A and 13B are not provided. The loose part of the fluid state such as diarrhea can be contained inside the flap parts 11A, 11B by hitting the bottom part of the flap member 11A, 11B with a wider space, and preventing the loose part from leaking. You can
Further, since the flap members 11A and 11B do not hit the hips, the hips do not feel uncomfortable when worn.

In each of the above four embodiments,
Although the absorbent article according to the present invention is applied to a so-called flat type diaper having elastic members 9A and 9B, it is not always necessary to have an elastic member, and the absorbent article according to the present invention is also included. The sex article can also be applied to a pants-type diaper formed by cutting out a portion that contacts the crotch. Further, the present invention can be applied to a disposable diaper of a type that is formed in a pants shape from the beginning, and it also has the same effect as that of the above-described embodiments.

[0033]

The disposable absorbent article according to the present invention is provided with the flap member, and the penis is held between the flap members, so that the penis is securely stored inside the absorbent article. Therefore, unlike conventional absorbent articles, the penis does not come off from the proper mounting position of the absorbent article because it is not worn properly, and the urine and other bodily fluids can be reliably absorbed by the absorbent article. You can

Further, the absorbent article according to the present invention can be easily manufactured by providing a flap member on the existing absorbent article as a base, and is extremely useful.
