Description

[Detailed Description of the Invention] The present invention relates to so-called menstrual shorts worn by women during menstruation.

Conventionally, various improvements have been proposed for this type of shorts in terms of materials, structure, design, etc., and have been put into practical use. In particular, shorts that use so-called four-way (4-way) fabric, in which the fabric is cut in three dimensions and sewn together to fit the wearer's body shape, and spandex is woven vertically and horizontally, are designed to fit the wearer's body shape. It is in good condition and is suitable for wearing during menstruation.
However, this type of shorts not only has a good overall fit to the body shape, but also allows the so-called sanitary napkin, which is worn to absorb and process menstrual blood, to fit properly against the wearer's genital slit. It is necessary to have a function that allows the underwear to maintain the tight fit, and if this function is not achieved, menstrual blood will leak and stain the underwear, causing discomfort. Although it cannot necessarily be said that the cause of menstrual blood leakage is simply due to the function of the napkin, the main cause can be said to be a problem with the ability of the napkin to hold the napkin tightly. It has not been resolved. By the way, the napkins that have been put into practical use in recent years have significantly improved their ability to absorb and prevent menstrual blood from leaking, and as long as they are kept in close contact with a woman's genitals, there is almost no chance of menstrual blood leaking from the napkin itself. .

An object of the present invention is to provide sanitary shorts that can effectively solve the above-mentioned problems.

The present invention will be described below based on the illustrated embodiments.

Fig. 1 is a plan view of each member constituting a short according to the present invention, Fig. 2 is a plan view of a part of each member sewn together, and Fig. 3 is a plan view of a short according to the present invention with the respective members sewn together. Shows the completed front view.

The shorts main body 1 is composed of a front body 2 and left and right rear bodies 3, and includes a crotch piece 4 and an elastic tape 5. The front body 2 and the left and right rear bodies 3 are preferably made of a known four-way woven fabric that is stretchable in the vertical and horizontal directions, and the crotch piece 4 is not only waterproof and breathable, but also preferably has the same stretchability as described above. A woven fabric having a stretchability in the longitudinal direction, more preferably a woven fabric having stronger stretchability in the longitudinal direction than in the transverse direction, is used. As the elastic tape 5, a bias tape having a width of 3 to 20 mm and woven with urethane fibers is preferably used.

The front body 2 and the left and right rear body 3 have edges 2a and 3.
a, edges 3b and 3b, the top of edge 2b and edge 3b
The elastic tape 5 is sewn together to form the shorts main body 1, from the crotch seam line 7 between the edges 2a and 3b to the waist circumference 3e along the central seam line 6 between the edges 2b and 2b. suture, and then main body 1
A crotch piece 4 is sewn to a predetermined location.

The first point to keep in mind here is that when the shorts (body 1) are worn, the inseam suture line 6 is located between the region 8 where the wearer's vaginal opening faces and the region 9 where the anus region faces. In other words, when the main body 1 is folded back at the center so that the waist surrounding edges 2c and 3e overlap, the front and back direction 25 is centered around the fold line 10.
This means that it is designed to be located within mm. The second point to note here is that the elastic tape 5 has elasticity in a portion of an appropriate length L from the rear edge 4a of the crotch piece 4 sewn to the main body 1 to the waist edge 3e of the left and right rear body 3. A gear section 5a is provided.
That's what it means. In order to provide the elastic gears 5a, the elastic tape 5 can be stretched and sewn to the main body 1, or the elastic tape 5 can be sewn to the main body 1 with gears formed.
Alternatively, if the main body 1 is made of stretchable fabric, the stretchable tape 5 is sewn with this part stretched. The length L of the elastic geared portion 5a is 15~
70 mm, and its elongation rate is such that the thing to be stretched is the elastic tape 5, the tape has a width of 5 to 20 mm made by incorporating urethane fibers, and the main body 1
If the fabric is commonly used for this type of shorts, for example, a tricot weave with a longitudinal elasticity of 100-200% and a transverse elasticity of 50-100%, it is 40-60%, The elongation stress is
Each weight is preferably 130 to 270 g.
If the length L is less than the lower limit, the desired effect will be low, and if it is more than the upper limit, when the shorts are worn, a part of the waistline will be pulled downward, resulting in a V-shape. Undesirable. Incidentally, the position of the stretchable gears 5a is near where the coccyx of the wearer is located, excluding the area facing the anus of the wearer.

It goes without saying that the size of the crotch piece 4 is the size necessary to hold the napkin, but taking this into consideration, it is generally 80 to 90 mm forward and upward from the crotch suture line 6. Formed posterosuperiorly to a length of 85 to 95 mm.

Since the shorts according to the present invention are constructed as described above, when worn with a napkin, the following effects occur, which can be seen in Figure 4, which shows the crotch area of the shorts in a plan view. Refer to and write.

The crotch part 12 of the shorts that is in contact with the napkin 11 (indicated by the imaginary chain line) is pulled in the direction of the arrow by the elastic tape 5, especially the elastic geared part 5a, and the stress is applied to the vicinity of the crotch seam 6. A strong pressing force acts on the napkin 11 in the area between the region 8 where the vaginal orifice of the wearer faces and the region 9 where the anus faces the wearer. A pressing force is applied in a planar manner in the vicinity of the crotch suture line 6, and in a linear or dotted manner from the area to the rear and upper areas, specifically from the crotch suture line 6 to the rear and upper sides. By the way, the area around the area 8 is the most important area for absorbing menstrual blood, and the napkin 11 located in this area has a planar shape in the area around the wearer's vaginal opening. It is preferable to make contact with the wearer's anus, and since the area extending from this area to the wearer's anus has a so-called V-shaped groove, pressing strongly along this area will prevent menstrual blood from leaking along this groove. This is preferable in order to effectively prevent this. However, since the pressing force acts on the crotch portion 12 as described above, the napkin 11 is brought into close contact with the wearer's body in the aforementioned preferred state. This state of close contact is stronger than that of conventional shorts and is therefore sufficiently maintained. In addition, this effect is the same for the main body 1 and the crotch piece 4.
It is even more effective when it has elasticity, but
According to the configuration of the present invention, they do not necessarily need to be stretchable.

Therefore, according to the shots according to the present invention, the intended purpose can be achieved and it is extremely useful in practical use.
