DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to sanitary napkins, urinary incontinence pads, vaginal discharge sheets, and other body fluid-absorbing articles.

[0002]

2. Description of the Related Art Conventionally, in sanitary napkins, urinary incontinence pads, vaginal discharge sheets, and other bodily fluid-absorbing articles, it has been proposed to enhance the wearability of shorts and other underwear and prevent leakage of bodily fluids. On both sides of the absorbent article, there are ones that project the wing body. As shown in FIG. 9, when the wing body is attached to underwear such as shorts (1), the absorbent article is attached to a crotch portion (2) that comes into contact with a user's crotch.
(3) was arranged, and the wing body (4) was fixed by folding back and bonding to the outer surface of the shorts (1).

[0003]

However, the crotch portion (2) of the shorts (1) for mounting the absorbent article (3) is
Both side edges (5) are curved in an arc shape with the center being narrow.
On the other hand, when the folded part (6) of the wing body (4) is folded,
Since the folding is performed linearly, when the wing body (4) is to be fixed to the crotch portion (2) whose both side edges (5) are curved, the folding portion (6) is twisted as shown in FIG. In addition, because of the infinite number of wrinkles caused by bending or sagging, the fit to the user's skin when worn is reduced. In addition, in the folded portion (6) where the wrinkles are formed, the touch during wearing is deteriorated, and at the same time, it is pressed by the user's inner crotch, and the twist is further worsened during use. Therefore, skin and absorbent articles
There is a problem in that a gap is formed in the gap with (3), causing lateral leakage of body fluid.

Also, the wing body (4) is end flap
The greater the size is formed in the direction (7), the more the bending and bending of the folded portion (6) increase, and the worse the mounting property of the absorbent article (3) becomes. Therefore, it is difficult to form the wing body (4) large in the direction of the end flap (7).
As shown in the figure, the absorbent article (3) had to be formed small on both sides near the center. And in such a wing body (4), the end flap (7) of the absorbent article (3)
Absorbent article before and after the crotch due to the activities during wearing, because both sides of the direction can not be fixed to the shorts (1)
(3) It was easy for the displacement and the distortion to occur. As a result, the wearing feeling of the absorbent article (3) is deteriorated, and at the same time, the body fluid is leaked, and the absorptivity is also reduced.

[0005] The present invention is to solve the above-mentioned problems, and by dividing the wing body provided in the body fluid absorbent article into a plurality of wing pieces, the shorts can be curved on both side edges. It is possible to fix well without causing twisting or bending. As a result, the touch and fit of the user are improved, and the mounting is prevented from being distorted or misaligned. And, to prevent body fluid leakage,
An object of the present invention is to provide the user with a comfortable feeling of use and to improve the functionality of the absorbent article.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a structure in which a water-permeable top sheet and a water-impermeable leak-proof sheet have a width wider than that of the top sheet and the leak-proof sheet. An absorbent body is formed by interposing an absorbent layer having a small body fluid absorbability, and side flaps and end flaps are provided on both sides and both ends of the absorbent layer of the absorbent body, respectively. In addition to forming a pair of wing bodies by protruding into the wing body, by forming a divided portion that divides the wing body into a plurality in the direction intersecting the length direction of the absorption body, on both sides of the absorption body, A plurality of wing pieces that can be folded back and fastened to the shorts outer surface are formed, and an adhesive portion for fastening to the shorts outer surface is provided on the leakproof sheet side of the wing pieces.

The wing body may be divided into two parts by providing a dividing part at the center, and two pairs of wing pieces are formed on both sides of the absorbing body.

The wing body may be divided into three or more parts by providing a plurality of divided portions, and three or more wing pieces may be formed on both sides of the absorption body.

Further, the absorbent body may be formed so that the end flap direction is wide and the central portion is narrow.

In the wing body, a notch may be formed in the folded portion of the wing piece so as to extend from the front surface to the back surface with a length not reaching both ends of the folded portion.

Further, the wing body may be easily formed so that the folded portion of the wing piece can be folded in correspondence with the crotch portion of the shorts.

The wing body may have a ratio of the formed length to the side flap of 0.1 to 1.0.

[0013]

Since the present invention has been formed as described above,
In order to use the absorbent article fixed to shorts or the like, the absorbent body is disposed inside the crotch portion of the shorts. Then, a pair of wing bodies protruding from both side edges of the crotch portion are folded back to the outer surface side of the shorts, and are fastened by the adhesive portion. Since both side edges of the crotch portion are formed in an arc shape having a narrow central portion, it is preferable that the wing body can be folded along the arc side edges. And, by providing this wing body with a divided part,
Each is divided into several small wing pieces. Then, each wing piece can be individually folded at different folding angles along the inclination of both side edges of the crotch portion. For this reason, the wing body can be folded back in accordance with the inclination of both side edges of the crotch portion without causing twisting or bending.

As described above, by providing the divided portion, the crotch portion can be folded back along both side edges of the arc shape, so that the respective wing pieces can be stably fastened. Therefore, the touch of the absorbent article and the fitting property to the crotch part are improved, and the wearing stability is improved, and the lateral leakage of the body fluid can be satisfactorily prevented. Also, even if the wing body is formed large in the end flap direction, since it is possible to fold back and fasten to the shorts back surface without wrinkles, this large wing body can be used before and after the crotch, Both sides of the absorbent article can be fixedly fastened to the shorts to improve stability. For this reason, the effect of preventing the absorbent article from being displaced or distorted due to the activity of the user is improved, and the lateral leakage and back leakage of the bodily fluid can be favorably prevented. And
In addition to giving the user a sense of security when wearing, it is possible to improve the absorption function of the absorbent article.

The wing body is provided with a plurality of divided portions and divided into a plurality of three or more divided wing pieces, so that the wing body can be fixedly fixed to both curved side edges of the crotch portion in a better manner. You can do it. However, if the number of wing pieces is too large, the number of fixing operations is increased, which is troublesome. Therefore, by providing the dividing portion at one place corresponding to the narrowest portion of the shorts, the wing body is divided into two, and two pairs of wing pieces are formed on both sides of the absorbing body. Since only the wing pieces are fixed, the number of fixing operations can be reduced. Moreover, since each wing piece can be folded back along both side edges of the crotch portion from the narrowest portion of the shorts toward the end flap direction, each wing piece can be fastened without wrinkling. Things become possible.

The absorbent body may be formed in a rectangular shape. However, if the end flap direction is widened and the central portion is formed narrow, the folded portion of each wing piece is formed on both side edges of the crotch portion of the shorts. It is arranged along the slope and can be reliably turned back from the base of the wing piece. Therefore, the fastening of each wing piece to the shorts can be performed more favorably by preventing the occurrence of wrinkles. In addition, by forming the end flap direction wide, the absorbent article can cover the entire surface of the crotch portion with the absorbent article. Therefore, the body fluid can be prevented from laterally leaking over a wide range before and after the crotch, and the absorption efficiency can be improved.

As described above, the wing body is divided into a plurality of wing pieces, and folded back along both side edges of the crotch portion for fastening. Since both side edges are arc-shaped, and the folded portion of the wing piece is straight, slight twisting or bending may occur. Therefore, at the folded part of each wing piece,
If a notch that penetrates from the front surface to the back surface is formed with a length that does not reach both ends of this folded portion, when the wing piece is folded along the curve on both side edges of the crotch portion, this notch expands And absorb the deflection and deflection. As a result, it is possible to effectively prevent wrinkles from being generated at the folded portion, and to perform the fastening of the wing pieces more favorably.

Further, the wing body is embossed on the folded portion so that the folded portion of the wing piece can be folded in correspondence with the crotch portion of the shorts.
If formed easily, the user can easily fix the wing piece at an accurate position, and the efficiency of mounting the absorbent article can be improved.

Even if the wing body is formed short in the direction of the end flap or longer than the absorbent article, good fastening to the shorts can be achieved. However, if the wing body is formed so that the ratio of the formed length to the side flap is shorter than 0.1, the wing body is too small, and good fastening becomes difficult. The wing body has a ratio of the formed length to the side flap of 1.
Even if it is formed longer than 0, the fastening effect of the absorbent article is not improved, resulting in waste of material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment in which the present invention is applied to a sanitary napkin will now be described with reference to the drawings. (11) is a surface sheet, such as a mesh sheet, a nonwoven fabric, a resin film provided with many small holes, and the like. Of water permeable material. On the back side of the topsheet (11), a leakproof sheet (12) made of a water-impermeable material such as polyethylene is arranged. Further, an absorbent main body (14) is formed by interposing an absorbent layer (13) that absorbs bodily fluid between the topsheet (11) and the leak-proof sheet (12). In addition, the absorption layer (13)
Composed of materials such as cotton, pulp and absorbent polymer,
It is formed narrower than the topsheet (11) and the leakproof sheet (12).

Then, the topsheet (11) and the leak-proof sheet (12) are fixed by heat sealing along the outer periphery of the absorbing layer (13), so that both sides and both ends of the absorbing body (14) are fixed. Each has a pair of side flaps (15) and a pair of end flaps (16). In addition, the absorption body (14)
The end flap (16)
As shown in FIG. 1, the side flap (15) has a symmetrical curved shape with a narrow center portion.

Further, a pair of wing bodies (18) that can be folded back and fastened to the outer surface of the shorts (17) project outside the side flaps (15). This wing body (18)
May be formed integrally with the absorbent main body (14) by projecting both sides of the topsheet (11) and the leak-proof sheet (12) in a wing shape, or may be formed separately from the absorbent main body (14). It may be formed and fixed to the side flap (15).

Also, the wing body (18) is formed so that both ends in the longitudinal direction are slightly closer to the center than the end flap (16), and is formed shorter than the side flap (15). I have. The ends of the side flaps (15) on the side of the end flap (16) are formed so as to protrude most outwardly, but the central portion of the wing body (18) protrudes outwardly wider than this formation width. Thus, the wing body (18) is formed in a diamond shape. Further, the central portion protruding outward is slit in the direction of the side flap (15) to provide a split portion (20) in the wing body (18).
The wing body (18) is divided into two triangular wing pieces (21) via the dividing portion (20).

In this way, as shown in FIG. 1, four wing pieces (21) are formed on the absorbing body (14) so as to cover almost the entire length of the side flap (15). The boundary between each wing piece (21) and the side flap (15) is embossed so as to be thin. Therefore, by making the embossed thin portion a folded portion (22), each wing piece (21) is easily folded. In the present embodiment, since the absorbing body (14) is formed in a gourd shape, the folded portion (22) of each wing piece (21) moves forward and backward through the dividing portion (20) toward the central portion. Becomes narrower in the shape of a triangle. Therefore, each wing piece
The folded part (22) of (21) is on both sides of the crotch part (23).
(24), it is arranged almost parallel.

Also, the leak-proof sheet (12) of the absorbing body (14).
On the side, as shown in FIG. 2, a hot melt or the like is applied to form a fastening portion (37). In addition, each wing piece (21)
A hot melt or the like is also applied to the back surface of the substrate to form an adhesive portion (38). Then, the fastening portion (37) and the adhesive portion (3)
By fixing 8) to the shorts (17), the fixing stability of the absorbing body (12) and the wing piece (21) is improved.

In order to use the sanitary napkin (25) as described above, as shown in FIG. 1, the leak-proof sheet (12) is absorbed while facing the inside of the crotch portion (23) of the shorts (17). The main body (14) is arranged on the fastening surface of the crotch portion (23), and is fastened and fixed by the adhesive force of the fastening portion (27) formed on the back surface of the leak-proof sheet (12). Next, the crotch part (23)
Pairs of wing pieces (21) projecting from both side edges (24) of the
Is divided from the dividing part (20), and each folded part (22)
And the back surface of the wing piece (21) is fixed to the outer surface of the crotch part (23) as shown in FIG. 3 by the adhesive force of the adhesive portion (28) formed on the back surface of the wing piece (21). Fix it.

In this fastening, both side edges (24) of the crotch portion (23) are arc-shaped so that the center portion is narrow.
In the conventional absorbent article (3), as shown in FIG. 9, the wing body (4) was liable to be twisted and bent. However, in the present embodiment, the wing body (18) is provided with the dividing portion (20) corresponding to the narrowest central portion of the crotch portion (23). Since the wing body (18) is divided into two wing pieces (21) by the dividing part (20), the two wing pieces (21) are separated by the crotch part.
From the narrowest part of (23), each end flap (16)
In the direction, folding can be independently performed at opposite folding angles.

Therefore, the folded portion of each wing piece (21)
(22) can be arranged almost in parallel to the inclination of both side edges (24), and can be folded back and fastened without causing twisting or bending. And each turn part after this turn
(22) is smooth without forming wrinkles,
Along with giving the user a good touch, the fit of the sanitary napkin (25) to the crotch can be improved,
The lateral leakage of the body fluid can be prevented well.

Further, since the wing piece (21) has good fastening stability, the fastening is not easily released even if it is pressed by the user's crotch during wearing. . Furthermore, both sides of the absorbent body (14) are almost completely shorts.
Since it is fixed to (17), it is possible to effectively prevent not only the central portion of the absorbent main body (14) but also the front and rear displacements and distortions. As a result, lateral leakage and back leakage of bodily fluids are reliably prevented, and a good sense of security and a feeling of use are provided to the user.

In the first embodiment, the wing body
The central part of (18) is formed wide and the wing body (18)
Is formed in a rhombic shape, but in another different second embodiment, as shown in FIG. 4, both sides of the wing body (18) are formed in parallel, and compared with the wing body (18) of the first embodiment. And narrow. In this case as well, the two pairs of wing pieces (21) divided through the division part (20) are folded back to the outer surface side of the crotch part (23) and fixedly fastened to the folded part (22). The entire side of the absorption body (14) can be fixed to the shorts (17) without wrinkling. Therefore, similarly to the first embodiment, a sanitary napkin (25) excellent in feel and fit can be obtained, and at the same time, it is possible to obtain a good feeling of wearing by preventing the napkin from being displaced or slipping. Furthermore, compared with the first embodiment, the sanitary napkin (25) can be formed more compactly, so that the storage efficiency can be improved and the cost can be reduced.

In each of the above embodiments, the wing body
Although the dividing portion (20) is formed by slitting (18), in another different third embodiment, as shown in FIG. 5, the central portion of the wing body (18) is enlarged in a V-shape. The cutout forms a division (20). Then
Since the wing pieces (21) adjacent to each other in the front and rear are formed apart from each other, it is easy to pinch the ends of the individual wing pieces (21) when folding the wing pieces (21).

In the first to third embodiments, the dividing portion (20) is formed by cutting off a part of the wing body (18). In the fourth embodiment, however, FIG. As shown, the dividing portion (20) is formed by perforating the wing body (18) during manufacturing. When the sanitary napkin (25) is used, the pair of wing bodies (18) are divided into two wing pieces (21) by breaking the perforations of the dividing part (20). After that, each wing piece (21) is turned back and the crotch portion (23)
It is to be fixed to the outer surface.

As described above, although it is troublesome to break the divided portion (20) during use, the sanitary napkin (25) can be removed by keeping the wing body (18) in the wing piece (21) during manufacture. When folded and mounted individually, the wing piece (21) does not flutter and does not disturb the work. Also, forming the divisions (20) at the perforations is easier and more workable than cutting off the wing body (18), and there is no dust, so that the efficiency of the manufacturing operation can be improved. Become.

When each wing piece (21) is formed long in the direction of the end flap (16), the wing piece (21) is curved in accordance with the curved shape of both side edges (24) of the crotch portion (23). It is necessary to turn back, and there is a possibility that some wrinkles may be generated in the turn-up portion (22). In order to further prevent the formation of wrinkles, the wing body (18) may be formed as in the following fifth and sixth embodiments.

First, in the fifth embodiment, as shown in FIG.
The folded part (22) of each wing piece (21)
A notch (26) is provided that extends from the front surface to the back surface and has a length that does not reach both ends of (22). Then, the wing piece
When turning back (21), the cut portion (26) expands and deforms to absorb twists and bends, so the crotch portion (23)
The wing pieces (21) can be properly fixed to the both side edges (24) of the curved shape. Therefore, the touch and the fit can be further improved, and a product excellent in the feeling of wearing and the effect of preventing displacement can be obtained.

Further, in each of the above-described embodiments, each wing body (18) is provided with one dividing portion (20). However, in the sixth embodiment, as shown in FIG. Each wing body (18) is provided in three places, and four wing pieces (21)
And a total of eight wing pieces (21) are formed on both sides of the absorption body (14). Therefore, as compared with the case where the wing body (18) is provided with only one division portion (20) as in the first to fifth embodiments and the wing pieces (21) are formed in total of four pieces, It takes time. However, since many small wing pieces (21) are folded back and fastened, each wing piece (21) is attached to both side edges (24) of the crotch portion (23).
It can be folded back by changing the folding angle finely according to the inclination of. Therefore, the folded portion of each wing piece (21)
The folded edge of the wing body (18) composed of (22) can be made closer to the curved shape of both side edges (24), and the wing body can be satisfactorily prevented by preventing wrinkles from occurring.
(18) can be fixedly fastened to the shorts (17).

[0037]

Since the present invention is constructed as described above, the wing body is divided into a plurality of wing pieces,
Since each wing piece can be fastened to the curvilinear side edges of the shorts without wrinkling, the user can feel good touch and fit. In addition, by improving the fastening stability, the body fluid-absorbing article is effectively prevented from slipping and twisting, so that even if the user is intensely active during wearing, the body fluid is well prevented from leaking and the user feels comfortable. , And a good feeling of wearing can be maintained.

Further, even if the wing body is formed long in the end flap direction, it is divided into a plurality of wing pieces and folded back by the dividing portion, so that good fastening without wrinkles can be achieved. Since the entire body fluid absorbing article is fixed on both sides, displacement and deflection during mounting can be reliably prevented. Therefore, it is possible to effectively improve the wearing feeling and the absorbing function of the body fluid absorbent article.
