The present invention relates to a sanitary napkin worn to absorb secretions, such as menstrual blood secreted during menstrual period of women, in particular provides a sanitary napkin having a function of preventing the leakage of menstrual blood, and prevents contamination of underwear or clothing due to leakage And it relates to a sanitary napkin having a leak-proof function to ensure the autonomy of the user's behavior.

In general, women are menstruating periodically when the age is appropriate, due to the contraction of the uterus secretion of a certain amount of secretions such as menstrual blood.

At this time, a sanitary napkin is used as a sanitary means for absorbing secretions such as menstrual blood.

These sanitary napkins are worn in underwear during the life cycle to absorb the secretions.

The ideal sanitary napkin is free of leaks and guarantees autonomy in the user's behavior, which makes the user comfortable.

This will be described with reference to FIG. 3 of the accompanying drawings.

Sanitary napkin 100 includes a liquid permeable top sheet 110, a liquid impermeable back sheet 120, and an absorbent member 130 that absorbs menstrual blood, and an absorbent member between the top sheet 110 and the back sheet 120. 130 is built in.

Since the top sheet 110 is in direct contact with the user's body, it is preferable that the top sheet 110 is made of a material having a soft and porous liquid permeability.

The back sheet 120 is made of a liquid impermeable material and has a bonding surface 142 on the bottom thereof so as to be attached to the underwear 140.

In addition, wings 122 surrounding the underwear 142 are formed on both sides of the back sheet 120 to prevent the menstrual blood from being contaminated by the underwear 140.

Since the wing 122 reduces the area of the underwear 140, contamination of the underwear 140 due to leakage was also minimized.

However, even when the sanitary napkin 100 is worn in close contact with the user's body, a predetermined gap occurs according to the movement or posture of the user.

These gaps will cause the leakage of menstrual blood, and the leakage will cause contamination of the underwear 140 or clothing.

In addition, the sanitary napkin 100 according to the related art has a flat contact portion with the skin, as shown in FIG. 3, so that adhesion between the sanitary napkin 100 and the skin is poor and leakage of menstrual blood occurs.

The present invention has been made to solve the above-mentioned conventional problems, the technical problem of the present invention is to increase the adhesion between the sanitary napkin and the skin to maintain the airtight, menstrual blood secreted during menstrual period of women by blocking multiple menstrual blood It is to provide a sanitary napkin with a leak-proof function to prevent the contamination of clothing due to leakage of the, and to ensure the autonomy of the user's behavior.

The present invention for solving the above technical problem,

A sanitary napkin comprising a liquid permeable top sheet, a liquid impermeable back sheet, and an absorbent member positioned between the top sheet and the back sheet and having a function of absorbing physiological blood,

The absorbent surface of the absorbent member is arranged in the longitudinal direction of the absorbent member formed by standing up the plurality of absorbent pieces at intervals so as to block and absorb the physiological blood multiplely, the absorbent pieces of the absorbent portion from the central region to the edge region It provides a sanitary napkin having a leak-proof function characterized in that the height is formed increasingly.

Such sanitary napkins are erected with a plurality of absorbent pieces for improving the absorbency at regular intervals, and are formed higher from the central region to the edge region, thereby improving adhesion to the body. In addition, the surface area where each of the absorbent pieces of the absorber is absorbed is increased to increase the absorbed capacity, thereby completely preventing the leakage of menstrual blood.

Therefore, contamination of underwear or clothing due to leakage of menstrual blood is also prevented, and thus the user can be guaranteed autonomy of behavior.

When described in detail with reference to the accompanying drawings a preferred embodiment of the present invention having such features as follows.

1 to 2 of the accompanying drawings, the sanitary napkin 50 according to the preferred embodiment of the present invention is a liquid permeable top sheet 30, a liquid impermeable back sheet 20, and the top sheet 30 ) Is positioned between the back sheet 20 and the absorbent member 10 having a function of absorbing menstrual blood.

In addition, the absorbent surface 11 of the absorbent member 10 includes an absorbent part 11 formed upright at regular intervals, preferably at equal intervals, with a plurality of absorbent pieces 15 to block and absorb multiple menstrual blood. Arranged in the longitudinal direction of the absorbing member 10, the absorbing pieces 15 of the absorbing portion 11 is formed higher toward the edge region 11A from the central region (11B).

This will be described in more detail as follows.

Since the top sheet 30 is a part which is in direct contact with the user's body, it is preferably made of a porous liquid permeable material so as not to be irritating, to use a soft and flexible material, and to be easily absorbed.

The absorbent member 10 has the most important function in the sanitary napkin 50, and is located between the top sheet 30 and the back sheet 20, and generally a layer of tissue for absorbing secretions such as menstrual blood. And fibrous pulp mills and the like, but are not limited thereto.

In addition, the upper surface of the absorbing member 10, that is, the absorbing surface 12 is formed with an absorbing portion 11 in which the absorption of secretions such as menstrual blood is concentrated. This absorbing portion 11 is generally rectangular in shape as shown in FIG.

Then, the absorbing pieces 15 constituting the absorbing portion 11 are formed to stand up at intervals as shown in Figs. That is, each of the absorbent pieces 15 is formed to protrude so as to stand up from each other at intervals from the absorbent surface 12 as shown in FIGS. 1 and 2.

Each of the absorbent pieces 15 may be formed of a soft material that is easy to bend when it is in contact with the body so as to absorb the menstrual blood.

On the other hand, the absorbing pieces 15 are formed different in height. In other words, the height is increased from the central region 11B of the absorbing surface 12 to the edge region 11A.

In other words, the height of the absorbing piece 15 of the edge region 11A of the absorbing surface 12 is formed higher than the height of the absorbing piece 15 of the central region 11B.

In this way, the edge region 11A is formed high such that the absorbent pieces 15 of the edge region 11A formed higher than the center region 11B when the respective absorbent pieces 15 are in close contact with the periphery of the body are surrounded by the periphery. In order to block a plurality of spaces 12A which are in close contact with each other and are formed between the periphery of the pubic part and the absorption surface 12.

That is, since the plurality of absorbing pieces 15 forming the edge region 11A are in close contact with the periphery of the pubic area, the menstrual blood is first absorbed from the central region 11B by each layer of the edge region 11A. Finally absorbed by the pieces 15 is prevented from leaking to the outside.

Such operation of the present invention will be described.

As shown in FIG. 2, when the absorbent pieces 15 constituting the edge region 11A of the absorbent part 11 are compressed and adhered to the periphery of the body, the menstrual blood discharged from the pussy is absorbed in the central region 11B. It is absorbed primarily by (15). At this time, since each absorbing piece 15 formed at equal intervals independently absorbs menstrual blood, the menstrual blood is sufficiently absorbed by the absorbing pieces 15 having a large area, and is moved to the edge side from the central region 11B. This is blocked by multiples.

This will be described in detail as follows.

Menstrual blood is absorbed by some absorbing pieces 15 of the central region 11B. Therefore, when the absorbent piece 15 exceeds the absorbent capacity of the absorbent piece 15 itself, the menstrual blood is absorbed by the neighboring absorbent pieces 15 arranged at equal intervals with the first absorbent piece 15, and the absorbed piece 15 again. If the absorption capacity of the excess is absorbed by another neighboring absorbing piece (15). As this process continues, menstrual blood is absorbed in each absorbent piece 15. Therefore, the menstrual blood is absorbed through the respective absorbing pieces 15 to prevent the phenomenon of menstrual blood leaking out of the sanitary napkin 50.

That is, by allowing the menstrual blood to be absorbed through the plurality of absorbing pieces 15, the menstrual blood is absorbed and blocked by the respective absorbing pieces 15 while moving from the central region 11B to the edge region 11A. . In other words, since each absorbing piece 15 absorbs menstrual blood at each position, it forms a kind of blocking film, and the effect of multi-blocking is shown.

On the other hand, the physiological blood that is not absorbed by the absorbent piece 15 of the central region 11B moves to the edge side while soaking the respective absorbent pieces 15, and finally to the absorbent piece 15 of the edge region 11A. Absorbed and leaked to the outside is prevented.

Absorbing pieces 15 of the edge region 11A are closely adhered to the periphery of the pubic area, so that each absorbs menstrual blood independently, thereby acting as a barrier to block multiple menstrual blood.

And, since each absorbing piece 15 is formed to stand up at regular intervals to each other, the area in which menstrual blood can be absorbed is enlarged, so that the absorption is remarkably improved. Due to this, the sanitary napkin 50 having the absorbent portion 11 according to the present invention has a remarkably high absorption capacity as compared to the flat sanitary napkin, and the menstrual blood is absorbed in multiple stages while passing through the various absorbing pieces 15. Therefore, the phenomenon of menstrual blood leaking out of the sanitary napkin 50 is prevented.

Thus, the preferred sanitary napkin 50 according to the present invention is formed on the absorbent surface 12 of the absorbent member 10 by the absorbent portion 11 made of a plurality of absorbent pieces 15 having an absorbent capacity, secretion such as menstrual blood To be absorbed in multiple, the leakage of secretions such as menstrual blood is blocked, thereby preventing the contamination of clothing such as underwear 40 in advance.

In addition, the absorbent member 10 having the absorbent part 11 as described above may be modified to be used in different applications such as incontinence pads, panty liners, diapers, everyday sanitary napkins, and overnight sanitary napkins.

In the sanitary napkin having a leak-proof function according to the present invention, a plurality of absorbent pieces are erected on the absorbing surface of the absorbent member in which the secretion such as menstrual blood secreted during menstrual periods is absorbed intensively, to block and absorb multiple menstrual blood. It is disposed in the longitudinal direction of the absorbent member, the absorbent portion is formed higher toward the edge region from the central region. According to such a sanitary napkin, a plurality of absorption pieces sequentially absorb multiple menstrual bloods, thereby providing an effect of preventing leakage to the outside. In addition, since the menstrual blood generated in the pubic area is first absorbed in the central area and finally absorbed in the edge area, the menstrual blood is prevented from leaking to the outside. This prevents the contamination of clothing such as underwear due to the leakage of menstrual blood, and completely eliminates the anxiety and discomfort that women feel during menstruation, thereby ensuring autonomy in women's behavior during menstruation. It has the effect of being.
