Abstract

The invention provides an improved sanitary towel, in particular to an improved sanitary towel, wherein a diversion groove is arranged in the center of a polymer absorption cotton body, a woven excellent layer capable of rapidly leaking is additionally arranged on the surface layer of a protection pad, and arc-shaped fins extending out from two sides of the protection pad are arranged. When the invention is used, besides the adhesive tape on the back side of the body, the adhesive tape on the back side of the wing piece can be used for fixing the underwear outside to strengthen the fixing effect. The invention is designed particularly aiming at the characteristics of female physiological structure, so that the female physiological structure can better meet the use requirement, and the effects of non-permeability, dryness and comfort during the menstrual period can be achieved.

Description

The present invention relates to an improved sanitary napkin, in particular, a guide groove is arranged in the center of the polymer absorbent cotton body of the gasket, a layer of woven fabric is added on the surface of the cotton pad, and the two sides of the cotton pad An improved sanitary napkin having extended curved sides.

Due to the physiological differences between women and men, women must face the menstrual period for five to seven days each month, and when the menstrual period comes, they need to use sanitary pads or tampons Menstrual blood can be absorbed to prevent menstrual blood from continuously flowing out and staining clothes. At the same time, using pads or tampons also has a cleaning function to prevent bacterial infection. Therefore, during women's menstrual period, sanitary pads are a very important item for women. Recently, due to the increase in manufacturing and production manufacturers, the types of sanitary pads also have different types and structures depending on the brand. Generally, they can be divided into several specifications such as standard type, single-piece portable type, and night-safe type for night use. , and its structure hardly departs from the following pattern: there is a soft-touch permeable surface layer on the top, a polymer absorbent cotton body inside, and an impermeable plastic thin layer on the bottom, and the thin layer extends to cover both sides of the cotton body to prevent menstrual blood It leaks from the sides, and the back has several lines of adhesive to fix it on the panties. However, most of the sanitary pads currently on the market are still not ideal when used. Because most women have to work as usual during menstruation, the amount of activity has not decreased. At the same time, the amount of menstrual bleeding is continuous, especially when the amount is heavy, the polymer absorbent cotton is very easy to reach saturation. If the pads are not replaced in time, the menstrual blood will easily seep from both sides and stain the underwear, which becomes a major trouble for women during menstruation. Most of the recent efforts to address this issue are aimed at the material, improvement, and continuous development of superabsorbent molecules for polymer absorbers, using ultrafine particles that can expand to several times their volume. However, no matter how strong the absorption force of the polymer absorbent is, the volume of the sanitary pad is always fixed. Moreover, because the absorbent cotton body is often squeezed during activities, the absorbed menstrual blood will be rearranged outside it, causing leakage. Therefore, we have to make a comprehensive design for the pad to prevent leakage and increase comfort.

One object of the present invention is to provide an improved sanitary napkin, which is designed according to the structure of the female human body, and a diversion groove is added in the center of the pad, so that menstrual blood can flow along the groove after flowing out of the human body And diffusion, in order to prevent leakage due to non-directional diffusion.

Another object of the present invention is to provide an improved sanitary napkin, which has arc-shaped wings extending from both sides of the pad, and adhesive backing is pasted on the back of the wings, so that the wings can be folded back to fix the underwear Bottom to strengthen the fixation of the pad to make up for the lack of adhesiveness of the back adhesive of the pad.

Another object of the present invention is to provide an improved sanitary napkin, which is covered with a layer of woven fabric on the pad material, and the surface layer of the pad is drier through its enhanced penetration structure.

In order to make the above-mentioned purpose, functions and structural features of the present invention be further understood, a detailed description will now be given below in conjunction with the accompanying drawings. The accompanying drawings of the present invention are only for supplementary description, and do not impose any limitation on the present invention.

Fig. 1 is the three-dimensional schematic diagram of the present invention;

Fig. 2 is the sectional view of the present invention;

Fig. 3 is a schematic diagram of the use state of the present invention.

Referring to the accompanying drawings, the present invention is provided with an appropriate groove 20 in the middle of the sanitary napkin 10. The groove 20 is composed of a long groove 21 and several short grooves 22 perpendicular to each other. The groove is designed according to the physiological structure of women and the shape of the sanitary napkin 10 when it is used. When the menstrual blood flows out from the crevice of the vulva, it first touches the part of the sanitary napkin 10 , that is, the long groove 21 . The menstrual blood flows quickly to the short groove 22 after being diverted by the long groove 21, and the absorbent cotton body 11 positioned on the sides of the long and short grooves 21, 22 quickly absorbs the menstrual blood, so that the menstrual blood will not be excessively large. There is a situation where it is too late to be absorbed.

On both sides of the sanitary napkin 10 there are arc-shaped wings 30 extending out, and the wings 30 on both sides are equal in size. Adhesive 31 is pasted on the back of the flap 30, so that the flap 30 can be pasted on the underwear by tearing off the adhesive backing paper after refolding the flap 30 in use, so as to strengthen the fixing of the pad and compensate for the adhesiveness of the pad. Insufficient, to avoid the situation that it is out of sliding due to the pressure of human body movement.

The absorbent cotton body 11 and the groove 20 of the sanitary napkin 10 are covered with a layer of woven excellent material 40. Through its special structure, that is, the characteristics of the hole being large and small, the water can quickly penetrate downward without being able to absorb water. Rewetting upwards ensures that the pads stay dry in contact with the body to prevent bacterial growth and increase comfort.

From the above description, it can be seen that the key point of the present invention is to design a sanitary napkin that can truly solve the inconvenience of the user. With a three-in-one structure, the sanitary napkin has the functions of rapid penetration, non-rewetting, rapid absorption, and stable positioning. It is a practical product.

Claims (1)
