Abstract

PROBLEM TO BE SOLVED: To provide a leakage preventive absorber used with a sanitary napkin for serving a joint between the napkin and a vaginal opening while preventing the occurrence of a gap resulting in the leakage of a menstrual blood using it with the sanitary napkin, and for preventing the leakage while providing the absorbing effect of the napkin, although the menstrual blood bleeds close to a coccyx as it has no contact with the napkin to possibly cause the stain of wears or a bedclothes when the gap exists between a body and the napkin during using the sanitary napkin coping with the menstrual blood. SOLUTION: An elliptically cut non-woven cloth 1 is banked with semi-egg shaped absorbing materials consisting of an absorbing polymer 2 and a water absorbing pulp layer 3 put thereon in sequence. The non-woven cloth 4 is mounted at the upper part and inserted between the sanitary napkin and a vulva portion in the form of sealing the absorbing materials 2, 3 to the shape of the nonwoven cloth 1 with their peripheries adhered with an adhesive 5, until it is deposited to the vulva portion with the vaginal opening as a center. Thus, the leakage of the menstrual blood is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary article used to prevent menstrual leakage when using a sanitary napkin.

[0002]

2. Description of the Related Art Among sanitary products, napkins are very commonly used, and have the advantage that they can be used easily and without any burden on the body regardless of generation. Dominates the mainstream. In recent years, practical sanitary napkins have been improved by using absorbent polymers and other materials to enhance the absorption capacity and improve the shape, eliminating concerns about leakage, realizing a thinner type, and having less sensation in use without cracking clothes. Widespread.

[0003] However, sanitary napkins cannot completely prevent leakage. Particularly at bedtime, since there is a very high risk of leakage, napkins having a large size and a high absorbency are widely used as napkins only for night use. When taking measures at bedtime to catch the menstrual blood that has flowed backward at the part that greatly extends to the back, if there is a gap between the napkin and the body with a large amount of menstrual blood The risk of leakage is very high, especially in the supine position. In that case,
The gap from the vaginal opening to the anus is located perpendicular to the bedding, and blood flows in the anus direction at a high speed without menstrual blood contacting the napkin central absorption part, so it is not possible to take advantage of the high absorption effect in the center, Menstrual blood that has reached the vicinity of the coccyx concentrates on the back of the napkin, which has low absorption, and leaks out of the absorption capacity. In many cases, menstrual blood stains clothes and bedding. For this reason, there is no measure for preventing leakage at bedtime other than the primitive method of increasing the size of the rear part so as to reach the waist even if the absorption power is increased. Also, since the enlarged napkins are thicker than general napkins, it can be seen that they are also used from the outside depending on clothes when used during the day, so they are not suitable for daytime use,
There are also reasons such as bulkiness for carrying, and it is necessary to use them separately for night and day use. Another major danger when using sanitary napkins is lateral leakage. As a countermeasure for causing side leakage, there is a wing type that extends like a blade on the side, but there is an advantage that covering the crotch part of the underwear prevents dirt on the underwear due to side leakage, but prevents side leakage At the same time, the napkin body has the wings, so the area spreads out to the outside of the shorts, creating a cause for expanding the permeation range of menstrual blood, and menses leaching to the outside of the underwear. Also, by covering the rubber portion of the crotch portion of the shorts with feathers, the band effect is impaired, a gap is easily opened on the side, and a cause of lateral leakage is created.

[0004] As a remedy, it is necessary to take a measure that does not create a gap between the napkin and the body. There is a method in which the center of the napkin is raised and closely attached around the vaginal opening. However, also in this method, since the napkin is fixed to the shorts by the adhesive tape, the napkin is linked to the movement of the shorts, but in this case, the movement of the body is not linked. Therefore, it cannot always be said that the vaginal opening and the napkin are in contact with each other, and if even a small gap is formed, leakage cannot be avoided. In any case, it is difficult to sleep well using sanitary napkins on many days, and the napkin has a drawback that leakage cannot be completely prevented.

[0005] As a method for completely preventing menstrual leakage,
Another use of a sanitary tampon is mentioned, but since it is an internal type that is directly injected into the vagina, there is a case that it may be difficult to use it, and it is not suitable for everyone.

[0006]

The problem to be solved is how to prevent the formation of a gap between the body and the sanitary napkin, which causes menstrual leakage.

[0007]

The present invention is characterized in that it is used in combination with a sanitary napkin. By installing an absorber between the vaginal opening and the napkin, it is possible to prevent a gap which is a cause of leakage, and Indirectly, a mechanism that acts as a relay that keeps the vaginal orifice in contact with the napkin at all times is guided to the center of the napkin without leaking menstrual blood. In addition, since the napkin is not integrated with the napkin but is completely independent of the napkin, the occurrence of a gap caused by the displacement of the napkin is prevented, and the napkin is always linked to the movement of the body. These are the most important features.

[0008]

Embodiments of the present invention will be described below. On the non-woven fabric 1 cut into an elliptical shape, the absorbent formed in the order of a water-absorbing polymer 2 and a layer 3 of water-absorbing pulp are piled in order, and the non-woven fabric 4 is covered from the upper part. This is an absorber having a shape in which the absorbers 2 and 3 are sealed and the peripheral portion is bonded with an adhesive 5 to leave an edge portion which is a bonding portion. It is inserted between the sanitary napkin and the vulva, and attached so as to fit directly into the vulva cavity centered on the vaginal opening. By eliminating gaps that cause menstrual blood leaks that occur when using sanitary napkins with the absorber, it prevents menstrual blood from flowing out and places the menstrual blood absorption trajectory in the center of the napkin with the highest absorbency. Play a guiding role. At the time of wearing, the vulva has no irregularities. This achieves a wider contact surface for the napkin and accurately guides menstrual blood to the napkin. In addition, when a plurality of independent absorbents are overlapped with each other, the liquid has a property of not being transferred to the next absorbent unless the absorption capacity of the closest one to the liquid is exceeded. Since the time required for menstrual blood to penetrate into the napkin is filled with menstrual blood after the leakage, the absorption capacity is increased as compared with the use of the napkin alone, and the necessity of replacing the napkin during bedtime is reduced. The peripheral adhesive portion A is provided to prevent deformation of the absorber due to movement of the body and to prevent a certain amount or more of entry into the vulva and deviation thereof, thereby producing an effect of maintaining a fixed position. . The absorbent was not integrated with the napkin, but was separated, eliminating displacement due to the movement of the napkin and achieving a high feeling of fixation by providing interlocking movement with the body.

[0009]

FIG. 4 is a perspective view of a mounting embodiment of the present invention.

[0010]

As described above, the leak preventive absorber of the present invention is mounted in a depression centered on the vaginal opening and plays a role of maintaining a constant shape on the edge side, thereby making it difficult for displacement to occur. The contact portion on the bottom always makes contact with the central portion of the napkin, so that menstrual blood leaking beyond the absorption capacity can be reliably absorbed in the central portion of the napkin, and menstrual blood does not flow out. for that reason,
Eliminates the need to use large napkins at night that are more expensive than at daytime at bedtime, is economical, eliminates the risk of leaks during menstruation with a large amount of menstrual flow, and reduces leakage compared to using napkins alone. The use of the absorption absorber increases the absorption capacity, eliminating the need to change the napkin while sleeping, and leading to a good night's sleep. Since it is an exterior type and has no burden on the body, it is suitable for everyone.
