DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below based on preferred embodiments with reference to the drawings. FIG. 1 shows a perspective view of one embodiment of the tampon of the present invention. The tampon 1 of the present embodiment has a cylindrical shape and has a tampon main body 2 having a substantially uniform thickness. The tampon main body 2 includes a substantially hemispherical tip portion 3 positioned at the tip end in the insertion direction, a rear end portion 4 positioned at the rear end in the insertion direction, and an intermediate portion positioned between the tip portion 3 and the rear end portion 4. 5. The front end portion 3, the rear end portion 4 and the intermediate portion 5 are integrated. A drawer string 6 extends from the rear end 4. Although not shown, the drawer string 6 is also present inside the tampon main body 2.
[0006]
The tampon body 2 is made of a liquid-absorbing material such as rayon fiber, cotton fiber, or a mixture thereof. These fibers preferably have a fineness of about 1 to 5 denier from the viewpoint of liquid absorption performance. The fiber length is preferably 20 mm or more, particularly 30 mm or more from the viewpoint of preventing the fibers from falling off. The tampon body 2 may contain a small amount of hydrophobic fibers.
[0007]
The tampon body 2 is obtained by rolling a plurality of sheet materials made of these liquid-absorbing materials into a roll and then compressing them into a cylindrical shape. The basis weight of this sheet material is about 40 to 100 g / m ² . When the sheet material is rolled up, a part of the drawer string is incorporated into the sheet material, so that the drawer string can be present inside the tampon main body 2 to be obtained.
[0008]
The drawer string 6 contains an odor control agent. Specifically, as shown in FIG. 2, the drawer string 6 has a breathable cylindrical structure, and an odor control agent 7 is included in the cylindrical structure. Examples of the drawer string 6 having a breathable cylindrical structure include, for example, a string knitted in a cylindrical shape with a water repellent treated cotton thread, and a thermoplastic resin having a liquid impervious and water vapor permeable micropore. And the like formed into a cylindrical shape. As will be described later, since the deodorant has a large number of particles, the pull-out string 6 has a smaller roughness than the particle size of the deodorant. The leading end of the drawer string 6 is sealed, for example, with an adhesive or the like, and the deodorant is prevented from falling off from the leading end.
[0009]
Although the length of the drawer string 6 is not critical in the present invention, it extends from the rear end portion 4 from the viewpoint of retaining a sufficient amount of the deodorizing agent for anti-odor and the handling property of the drawer string 6. It is preferable that the length of the portion is 80 to 150 mm, particularly about 100 to 120 mm. Further, the inner diameter of the cylindrical structure in the drawer string 6 is also determined from the same viewpoint , and is 1 to 3 mm. It is preferably 5 to 2 mm. In the tampon 1 shown in FIG. 1, there is one drawer string 6, but a plurality of drawer strings may be used instead.
[0010]
By including the odor control agent in the drawer string 6, the odor during menstruation is suppressed, and the odor is not perceived by the wearer and others. Since the odor control agent is contained in the inside of the drawer string 6, there is no possibility that the odor control agent falls off and scatters and remains in the vaginal cavity while the tampon is worn.
[0011]
The drawer string 6 contains an odor control agent over its entire length. Accordingly, a portion of the drawer string 6 existing inside the tampon main body 2 also contains an odor control agent. As a result, the tampon body 2 that is closer to the source of odor than the drawing string 6 is also provided with odor control performance, and the odor during menstruation is further suppressed. In addition, there is no risk that the deodorant will fall off and scatter and remain in the vaginal cavity.
[0012]
The odor control agent in the present invention means general substances that suppress bad odors such as deodorants and deodorants that absorb bad odors, deodorants that prevent bad odors, and fragrances that mask bad odors with other odors. . Specific examples of these agents are as follows. These agents can be used alone or in combination of two or more.
[0013]
Deodorants and deodorants include (1) activated carbon, fiberized carbon adsorbent, zeolite, amorphous silica, clay minerals such as bentonite, physical adsorption deodorizer such as activated alumina and acid clay, (2) acid agent, alkaline Chemical deodorants such as oxidants, oxidants and reducing agents, (3) physical or chemical deodorants such as zeolites adsorbed with alkaline or acidic impregnated activated carbon, vegetable essential oils, and (4) iron phthalocyanine derivatives, zinc oxide, etc. Examples thereof include a salt having a desulfurizing action, a mixture of an iron (II) compound with L-ascorbic acid and alum.
[0014]
Examples of the deodorizer include chelating agents containing metal ions such as silver, zinc and copper, and substances carrying these metal ions (for example, metal ion impregnated zeolite).
[0015]
As fragrances, (1) glycosides of fragrances such as glucosides composed of alcohol fragrances, monosaccharides, oligosaccharides and polysaccharides, (2) glycerin and carboxylic acid fragrances (benzoic acid, cinnamic acid, etc.) And glycerides such as monoglyceride, diglyceride and triglyceride, and (3) amino acid derivatives or peptide derivatives of alcohol-based fragrances, carboxylic acid-based fragrances or amine-based fragrances (indole, skatole, etc.).
[0016]
Furthermore, high molecular organic materials such as polygalactosamine, chitosan, chitin, polyethyleneimine, and polyaniline can also be used as an odor control agent. Of these, chitosan is particularly preferable from the viewpoint of stability as a polymer and low odor. Polycarboxylic acids such as polyacrylic acid, polymethacrylic acid, polycrotonic acid, polyitaconic acid, and polymaleic acid can also be used. Of these, polyacrylic acid or polymethacrylic acid, particularly polymethacrylic acid, which has a low acidity and is easily salt-exchanged with an acidic odor substance, is preferred.
[0017]
Among the above various system odorant, Ru used as the powdery from the viewpoint of handling property of the drawer for string 6 during processing or use. Specific examples thereof include particulate activated carbon used as a deodorant, zeolite powder, silica gel powder and the like.
[0018]
Although depending on the type of odor control agent, the odor control performance is effectively expressed when the odor control agent is contained in an amount of 5 to 80%, particularly 20 to 70%, based on the weight of the tampon body 2. This is preferable.
[0020]
The present invention is not limited to the embodiment. For example, in order to maintain the appearance and odor control performance, the drawer string 6 may contain various colorants, water repellents, surfactants and the like in addition to the odor control agent.
