Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a means for fixing a sanitary napkin, that is, a means for preventing slippage when worn.

Conventionally, in order to prevent sanitary napkins from slipping when worn, adhesive materials such as double-sided tape or hot melt were pasted or applied to the napkin body, or
Methods such as providing a means for fixing the napkin to a menstrual belt such as shorts have been adopted.

However, in the former case, the above-mentioned adhesive means has the drawback that its adhesive and friction properties change due to variations in components, deterioration over time, changes in environmental temperature, etc. That is, in the winter, the adhesive and frictional properties decrease, making the napkin easy to slip off while being worn, while in the summer, the adhesive and frictional properties increase, resulting in problems such as adhesive remaining on the shorts. Furthermore, when an adhesive is provided on the napkin body as described above, a release paper is usually attached to the adhesive part to protect the adhesive surface, and the release paper must be removed and discarded each time it is used. It was an unavoidable annoyance.

On the other hand, in the latter case, a stopper or the like is generally used as a means for fixing the napkin, but these means not only impair the feeling of use, but also have the inconvenience of requiring time and effort to put on the napkin.

Therefore, the present invention was devised to overcome the above-mentioned drawbacks of the prior art, and the purpose of the present invention is to:
To provide a means for fixing a sanitary napkin that can always exhibit a constant slip-preventing function regardless of temperature changes, etc., and does not require any troublesome procedures during use.

That is, the present invention is characterized in that a foamed elastic flexible member is fixed to the surface of the sanitary napkin that is adjacent to the wearer's clothing when worn, and a number of opening holes are formed in the surface of the sanitary napkin. be.

Next, the present invention will be explained based on the drawings.

FIG. 1 shows an embodiment of the sanitary napkin fixing means according to the present invention, which is shown upside down, that is, with the bottom side facing up.

A sanitary napkin 1 shown in FIG. 1 is similar to a known general sanitary napkin, and includes:
Basically, it consists of a water-permeable top sheet 11 made of nonwoven fabric, etc., a water-absorbing layer 12 of paper cotton, water-absorbing paper, etc. wrapped in this water-permeable sheet 11, and a water-impermeable film such as a plastic thin film. The waterproof layer 13 covers the bottom and side surfaces of the layer.

A foamed elastic flexible material 2 is fixed to the lower surface of the sanitary napkin 1, that is, the surface 1a adjacent to clothing such as shorts when worn. The foamed elastic flexible material 2 may be fixed to the napkin lower surface 1a by heat fusion as shown in FIGS. This may be done by pasting or applying adhesive means 22 such as double-sided tape or hot melt to one side 2a of the material 2. The adhesive means 22 may be applied to the entire surface 2a of the foamed elastic flexible material 2, or may be applied to a part thereof.

In any case, in the present invention, as shown in FIGS. 1 and 2, a large number of holes 21, 21, . This will be increased. Note that illustration of the hole 21 is omitted in FIG. 3.

The material of the foamed elastic flexible material 2 may be any material as long as it has sufficient frictional resistance, elasticity, and flexibility on at least one side thereof. A preferred material is soft polyurethane foam. When adhering to the napkin 1 using an adhesive, it is preferable to use polyurethane foam with a skin so that the adhesive does not pass through the polyurethane foam and transfer to the clothing side.

The foamed elastic flexible material 2 is the lower surface 1a of the napkin 1.
It may be provided over the entire surface, or it may be provided only on a part of it. In this case, the foamed elastic flexible material 2 only needs to have a size that can generate sufficient frictional force with clothing such as shorts and hold the napkin 1 in a predetermined position. The thickness of the foamed elastic flexible material 2 is usually preferably about 0.5 to 5 mm.

The number of foamed elastic flexible materials 2 to be attached to one sanitary napkin 1 may be one or more. The mounting position on the napkin 1 is not particularly limited, and it can be provided at the adhesive application position on a normal napkin. In this case, the foamed elastic material 2 may be further provided on the other longitudinal side of the napkin 1. The shape of the foamed elastic material 2 is not particularly limited. Therefore, for example, it may extend over the entire length of the napkin 1;
If it is within the range of the unused surface of the napkin 1
It may be of a shape that covers the entire lower surface of the.

As described above, according to the present invention, the sanitary napkin is fixed when worn by pasting the foamed elastic flexible material without using adhesive means, so that the adhesive friction force depending on the season etc. There is no fluctuation in the frictional force, and a constant frictional force can be maintained at all times, thereby achieving reliable slippage prevention. Furthermore, the elasticity of the foamed elastic flexible material improves the cushioning properties and greatly enhances the shape retention of the napkin against twisting during use. Further, since no steps are required when using the napkin, it can be worn extremely easily.

In particular, in the present invention, since a large number of holes are formed on the surface of the foamed elastic flexible material, when the napkin is deformed due to body shape or body movement, bending deformation is facilitated at the large number of holes. Therefore, unlike the case where there are no holes, the napkin is easily deformed and the fit is improved. Moreover, when the napkin deforms or tries to shift, the flexible material itself has a slip-preventing effect, and the numerous holes prevent the napkin from shifting.
It acts as frictional resistance and has a great anti-slip effect.
