Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention is a sanitary napkin, especially a sanitary napkin that directly adheres to and holds the wearer's skin. Regarding napkins.

0002

[Conventional technology]

Sanitary napkins are used by holding them under the wearer's crotch. Various techniques have been proposed for holding such sanitary napkins under the crotch. For example, Japanese Utility Model Application Publication No. 166323/1983 describes the back side (back side) of sanitary napkins. A strip of adhesive tape is placed on the sanitary pad surface), and the adhesive tape is attached to the sanitary pad when worn. Adhesively fix it to shorts or pants to hold the sanitary napkin at the excretion point. The technology has been disclosed.

[Problem that the idea aims to solve]

However, with the former conventional technology, the sanitary napkin is fixed to the side of the sanitary shorts. It is not fixed to the wearer, so sanitary shorts are not attached to the wearer. If the sanitary napkin slips, there is a problem that the sanitary napkin also slips. Ru. Especially when walking or doing strenuous exercise, sanitary shorts tend to slip off easily. There is a problem that the sanitary napkin slips away from the excretion point, causing leakage of menstrual blood. Ru.

[0005] With the latter conventional technology, which has an adhesive on the top sheet side, it is difficult to wear sanitary napkins. Because it adheres directly to a person's skin, sanitary napkins may be damaged due to slippage of sanitary shorts, etc. There is little misalignment of the sanitary napkin, but the difference between the back sheet of the sanitary napkin and the sanitary shorts If the friction between There is a problem in that the sanitary napkins gradually shift. Position due to such frictional force In order to prevent slippage, it is possible to strengthen the adhesive strength of the adhesive, but If the adhesive strength is too strong, it may damage the skin or cause pain when peeled off, so do not use adhesive. You can't just increase the strength. Also, the size of sanitary napkins is limited. Therefore, the adhesive surface cannot be made very wide.

[0006] Thus, conventionally, sanitary napkins cannot be held securely by the wearer. There is a problem. Therefore, the purpose of the present invention is to ensure that the absorbent article is held at the point of excretion. Our goal is to provide sanitary napkins that can.

[0007]

[Means to solve the problem]

This invention consists of a liquid-permeable surface material, a liquid-absorbing absorber, and a liquid-impermeable leakage prevention material. In a sanitary napkin made of a laminated layer of An adhesive that sticks to the skin is placed on the surface of the non-skin contact side of the liquid-impermeable leak-proof material. Provided is a sanitary napkin characterized by using a member with a coefficient of 0.3 or less. By doing so, the above objectives were achieved.

[0008]

[Effect]

When wearing the sanitary napkin of this invention, the adhesive provided on the liquid-permeable surface material side The agent adheres to the wearer's skin and is directly fixed to the wearer, and while wearing it, the sanitary napkin By installing a member with a specific friction coefficient on the leak-proof material side of the sanitary napkin, Even if the hood slides against underwear such as shorts and causes friction with the underwear, the frictional force will cause damage. No misalignment occurs.

[0009]

【Example】

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIGS. 1 and 2, the sanitary napkin 1 according to the embodiment of the present invention is liquid-permeable. A permeable surface material 6, a liquid-absorbent absorbent body 2, and a liquid-impermeable leakproof material covering the absorbent body 2. material 3 are laminated, and a sliding member 4 is further provided on the outside of the liquid-impermeable leakage prevention material 3. An adhesive portion 5 as an adhesive is provided on the liquid-impermeable surface material 6 side. It is.

0010 The absorbent body 2 is formed into a flat shape and is made of absorbent fibers mainly made of defibrated pulp. It is filled with fibers. The liquid-impermeable leakage preventive material 3 is provided so as to wrap around the absorber 2. liquid free The permeable leakage prevention material 3 is made of thermoplastic resin film molded, wet nonwoven fabric, or paper. It is preferable to use a composite material laminated with a thermoplastic resin.

[0011] A sheet-shaped sliding member 4 is disposed on the outside of the liquid-impermeable leakage prevention material 3. Slippery The shearing member 4 has a sufficiently small friction force with respect to the shear resistance force of the adhesive part 5 disposed on the skin contacting surface side. As the material having a friction coefficient, a member having a surface friction coefficient of 0.3 or less is used. The materials for the above members include dry non-woven fabrics such as Spunpond and Heat Bond, as well as suitable materials. Embossed films, net-like materials, foam sheet materials, etc. that have a suitable surface condition are used. In particular, dry non-woven fabrics that are flexible and stretchable, and those that have an appropriate surface condition. An embossed film having the following is preferred.

0012 The friction coefficient of the sliding member 4 used in this invention is KES-SE (Kato Tech Co., Ltd. (manufactured by Shikisha) under a load of 50 gf. Use 0.5mm wire for the friction element. 0.3 or less, preferably 0.26 or less. 0.3 In the above case, it follows the shorts, etc., and the problem occurs due to the positional shift of the shorts, etc. This is because the sanitary napkin 1 will shift.

[0013] The adhesive part 5 is arranged so as to extend to the outside of the napkin. Such adhesive part 5 Adhesives based on normal water-permeable polymer compounds, lipophilic polymer compounds as the main ingredient Adhesives are used as adhesives, and the release film on the adhesive must be peeled off before use. It has become so. When using the sanitary napkin 1 according to this embodiment, first, refer to FIGS. 1 and 2. Peel off the release tape (not shown) from the state shown and see the adhesive area where the adhesive is placed. The front side of No. 5 is applied to the wearer's crotch excretion point and fixed directly to the wearer's skin with adhesive.

[0014] While wearing the sanitary napkin 1, the sanitary napkin 1 will not touch the wearer during walking or strenuous exercise. Since it is directly fixed with adhesive, it follows the movements of the wearer and moves to the designated excretion point. It is securely held without shifting from the position. On the other hand, underwear such as shorts cannot follow the movements of the wearer. Misalignment may occur. If such misalignment occurs, the shorts may become worn out. It rubs against the back side of the sanitary napkin inside, and the friction force causes the sanitary napkin 1 to I try to shift the position, but there is a slippery surface with a sufficiently small coefficient of friction on the back of the sanitary napkin 1. Since the friction member 4 is arranged, almost no frictional force is applied, and it can be easily worn by shorts etc. This prevents the sanitary napkin from shifting.

[0015] The sanitary napkin of the present invention is not limited to the above-mentioned embodiments, but the sanitary napkin of the present invention is It can be modified in various ways without departing from the gist, and the adhesive part is arranged on the liquid-permeable surface material side. A member with a surface friction coefficient of 0.3 or less shall be placed on the liquid-impermeable leakage prevention material side. Bye. For example, in the above embodiment, the member with a surface friction coefficient of 0.3 or less is a liquid-impermeable barrier. They are stacked on the outside (lower side) of the leak material 3, but at least the back material side is 0. Any material having a friction coefficient of 3 or less may be used.

[0016] Further, as shown in FIG. 3, the adhesive portion 5 is approximately parallel to the longitudinal end of the napkin. As shown in Figure 4, the leakage preventive material 3 has a friction coefficient of 0.3 or less. If you apply a treatment such as sea urchin embossing, there is no need to layer sliding materials on the outside. Furthermore, as shown in FIG. 5 and FIG. If the sanitary napkin has a Good. Also, members with a surface friction coefficient of 0.3 or less do not need to be made of a single material. If the coefficient of friction is 0.3 or less, it is made of two or more materials, and it has a planar, dotted or They may be arranged linearly or linearly.

[0017]

[Effect of the idea]

According to the sanitary napkin of the present invention, the absorbent article is securely held at the excretion point. can be done. In other words, an adhesive part is provided on the skin-contacting side, and a specific frictional part is provided on the opposite side. By arranging a number of members, it improves the slipperiness with shorts. The effectiveness of the adhesive part can be further improved, making the absorbent article more resistant to any movement. It can be held securely at the excretion point.

[0018] Furthermore, it has less slip resistance with shorts, reducing the area and strength of the adhesive part. It is also possible to attach the adhesive to the skin, significantly reducing the discomfort caused by adhesion to the skin. is possible.
