Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sanitary napkin.

[0002]

[Prior art]

 Conventionally, as a sanitary napkin, a thin and long sheet-shaped sanitary napkin, or a band-shaped absorber for absorbing blood, as disclosed in Japanese Utility Model Laid-Open No. 5-18523, for example, is used. It is known that an elongated portion corresponding to the female genitalia is made thicker than the other portions, and the increased thickness is projected to a surface pressed against the female genital vein.

[0003]

[Problems to be solved by the invention]

 However, with conventional sanitary napkins, the gap between the body and the body is not sufficiently closed, and on days where there is a lot of bleeding, even if you sit and stand, there is a lot of leakage, and you have to worry about stains on clothing etc. Did not.

[0004] An object of the present invention is to provide a sanitary napkin that fits well on the body and can prevent leakage of menstrual blood and the like, and can be used easily, comfortably, and comfortably.

[0005]

[Means for Solving the Problems]

 According to a first aspect of the present invention, there is provided a sanitary napkin having a liquid-absorbent core interposed between a liquid-permeable top sheet and a liquid-impermeable back sheet. A sanitary napkin having a projection made of a liquid absorbing member formed at a predetermined position on a liquid-permeable topsheet side on a center line in a width direction, which is inserted into a vaginal part.

[0006] In the invention according to claim 2, the projection formed of the liquid absorbing member, which is inserted into the vagina local part, is formed integrally with the liquid permeable surface sheet and the liquid absorbing core in the body of the napkin for treatment. The sanitary napkin according to claim 1, wherein the sanitary napkin is used.

According to a third aspect of the present invention, a liquid guide portion is formed between the liquid-permeable surface sheet and the liquid-absorbing member in the protrusion formed of the liquid-absorbing member, which is inserted into the vagina. A sanitary napkin according to claim 1 or claim 2.

[0008]

[Embodiment of the invention]

 Hereinafter, the present invention will be described based on its preferred embodiments.

FIG. 1 is a perspective view of the sanitary napkin of the present invention. FIG. 2 is a sectional view taken along the line AA in FIG. In FIGS. 1 and 2, reference numeral 1 denotes a liquid-permeable top sheet, which can be made of a synthetic resin-based nonwoven fabric having excellent liquid permeability, and the surface of which is covered with a non-liquid-absorbing mesh sheet. You may.

Reference numeral 2 denotes a liquid-impervious sheet on the back surface, which is made of a synthetic resin-based nonwoven fabric having excellent waterproof properties. A protective sheet may be laminated on the outer surface. Reference numeral 3 denotes a liquid-absorbing core, and a material having excellent liquid-absorbing properties is selected. For example, a mixture of fluff pulp and superabsorbent polymer particles can be used.

As shown in FIG. 1, reference numeral 4 denotes a protrusion which is formed at an appropriate distance from the widthwise center and the longitudinal end of the napkin for insertion into the vaginal part of the female genitalia. Is done. The protrusions 4 may be detachably formed on the sanitary napkin main body, but are formed integrally with the liquid-permeable top sheet 1 and the liquid-absorbent core 3 in the sanitary napkin main body as shown in FIG. Things are hard to come off on use and are convenient.

In the embodiment shown in FIG. 2, the protrusion 4 is formed integrally with the liquid-permeable top sheet 1 and the liquid-absorbent core 3 of the sanitary napkin main body. When a liquid guide member is inserted between the liquid-permeable topsheet 1 and the liquid-absorbent core 3, menstrual blood and the like are easily absorbed from the protrusions 4 to the liquid-absorbent core 3 in the sanitary napkin body. . As the liquid guide member, for example, a material having excellent liquid permeability and diffusibility such as tissue paper can be suitably used.

According to the knowledge of the inventors, the position where the protrusion 4 is formed is in the width direction on the liquid-permeable topsheet 1 side of the sanitary napkin main body having a width of about 75 mm to 100 mm and a length of about 200 mm. It is easy to use a position 70 mm to 80 mm from the center and one end in the length direction. Further, the dimensions of the projections 4 are suitably 15 mm to 20 mm in diameter and 10 mm to 25 mm in height. Further, the plane size of the sanitary napkin main body may be the above-mentioned size, but if the sanitary napkin body is to be used only at night, the rear surface may be longer.

By inserting the projections 4 configured as described above into the female vaginal vaginal area, gaps are eliminated, and menstrual blood or the like is concentrated at one point by capillary action and absorbed by the absorbent core 3. This eliminates the risk of menstrual blood leaking along the surface of the skin. In addition, there is no discomfort or anxiety as when using a tampon, and it can be used easily, comfortably, and comfortably.

[0015]

【Example】

 Width: 85 mm, length: 200 mm, at the center in the width direction and in the length direction of the sanitary napkin body having the liquid-absorbent core 3 interposed between the liquid-permeable top sheet 1 and the liquid-impermeable back sheet 2. A protrusion 4 having a diameter of 18 mm and a height of 20 mm was formed integrally with the liquid-permeable surface sheet 1 and the liquid-absorbent core 3 in the sanitary napkin body at a position 75 mm from one end. A liquid guide member was interposed between the liquid-permeable topsheet 1 and the liquid-absorbent core 3 in the projections 4. When a few women used the sanitary napkin of the present invention constructed in this way, it was easy to use and could be used safely on days with bleeding and without fear of leakage.

[0016]

[Effect of the invention]

 Since the present invention has the structure described above, it fits well to the body, eliminating the gap between the sanitary napkin and the body, and allows menstrual blood to flow at one point by capillary action and absorbed by the absorbent core. Can eliminate the worry of leakage. In addition, there is no discomfort or anxiety as when using a tampon, and it can be used easily and safely. Further, by narrowing the absorption to one point, the bleeding does not propagate on the surface of the skin, so that it is possible to prevent rough skin.

According to the second aspect of the present invention, since the protrusion is formed integrally with the liquid-permeable surface sheet and the liquid-absorbent core of the sanitary napkin main body, the protrusion can be securely attached to the body. There is no worry about things coming off.

According to the invention as set forth in claim 3, since the liquid guide member is inserted between the liquid-permeable topsheet and the liquid-absorbent core in the protrusion, the sanitary napkin such as menstrual blood is used. Intensive absorption into the liquid absorbing core of the body can be further promoted.
