Description

[Detailed Description of the Invention] The present invention relates to a tampon that is used by being inserted into the vagina, and particularly to a so-called menstrual tampon that is used to absorb menstrual blood.

Generally, tampons that are inserted into the vagina are equipped with a pull-out string that extends from the rear end of the tampon body, which is made of a liquid-absorbing material that is compressed into an appropriate shape. Sometimes it ends up hanging between the wearer's crotch.

Conventional tampon drawstrings are constructed from knitted or twisted yarns made of hydrophilic fibers.

Such a drawer string has the property of absorbing liquid due to its material itself, and also has the property of causing a capillary phenomenon due to its structure having minute gaps between fibers and threads.

Therefore, when you enter a bathtub, swimming pool, etc. while wearing a conventional tampon, bacteria such as E. coli present in the water inside the tampon are absorbed by the drawer string and transmitted through the drawer string due to capillary action and enter the vagina. If the drawer string comes into contact with the anus while wearing a tampon, bacteria can also travel along the string and enter the vagina, causing vaginitis.

On the other hand, when wearing a tampon, menstrual blood absorbed by the tampon body may transfer to the drawer string and smear red, causing discomfort to the wearer, or may transfer to the panties and stain them. was there.

Incidentally, even if the drawer string is made of a hydrophilic material as in the past, if it is waterproofed, a certain effect can be obtained.

However, in order to mass produce tampons, the drawer string is used by cutting a long string that is continuously wound into the appropriate length for one tampon, so there are cut surfaces at both ends. Liquid absorption and capillary action will occur from the surface to the inside.

Therefore, this waterproofing cannot be said to be sufficient for preventing the invasion of bacteria.

SUMMARY OF THE INVENTION The object of the present invention is to provide a tampon with a pull-out string that is extremely effective in overcoming the above-mentioned drawbacks.

The structure of the present invention for achieving this purpose will be described below based on the illustrated embodiments.

The tampon is composed of a tampon body 1 and a drawstring 2.

The main body 1 is formed into a cylindrical shape by compressing a liquid-absorbing material such as a known material conventionally used in this type of tampon.

The string 2 is made of a hydrophobic monofilament-like material having no knitted/twisted structure, such as synthetic resin, and extends from the rear end of the main body 1.

As the hydrophobic monofilament, a synthetic resin material having the required tensile strength and flexibility is preferably used.

Although the method of attaching the string 2 to the main body 1 is not particularly limited, the string 2 may be attached, for example, as follows.

That is, as shown in FIG. 2A, a string 2 is folded in half and hung across the absorbent material 1a cut into strips and laminated in the width direction, and a pull-out end 2b is attached to the loop 2a. The string 2 can be attached by inserting the string 2 through it and tying it, or by sewing the string 2 to the liquid-absorbing material 1a which is cut into a rectangular shape and laminated as shown in FIG. 2B, leaving the pull-out end 2b.

The material 1a shown in FIG. 2A is rolled into a spiral cylindrical shape, and the material 1a shown in FIG. 2B is compressed or shaped into the shape of the main body 1 in that state. In addition to columnar shapes, they may also be elliptical, spherical, etc.

As mentioned above, the tampon of this invention has a knitted drawer string.
Since it is made of a twisted structure, that is, a hydrophobic monofilament-like material that does not have a microscopic gap structure, it goes without saying that the material itself will not absorb liquid even if it comes into contact with liquid.
It does not cause capillary action, therefore all of the conventional drawbacks mentioned above can be overcome and it is hygienic.

As described above, although the tampon of the present invention has a simple structure, it has excellent effects and is extremely useful.
