Description

Sanitary napkin having inner pad {Hygienic band having inner pad}

The present invention relates to a sanitary napkin having an inner pad that is coupled in a detachable structure, and more particularly, to a sanitary napkin in which a separate inner pad is coupled to a main pad in a detachable structure.

Sanitary napkins are attached to the inside of underwear to absorb menstrual blood and vaginal secretions (hereinafter referred to as 'menstrual blood') when women menstruate, and pad-type sanitary napkins sold in the market are mainly used.

However, in the process of manufacturing sanitary napkins, many kinds of chemicals are used, the absorbent cover of the sanitary napkin is made of polyvinyl-based material, and the cotton inside the sanitary napkin uses an absorbent gel (polyacrylate), a granular chemical, to increase absorption. do.

The chemical products are inexpensive and easy to manufacture, and are widely used, including disposable diapers for babies and women's sanitary napkins. In addition, there is a disadvantage that the chemical is harmful to the human body by using it in close contact with the body.

In addition, since the sanitary napkin is a disposable product, it must be replaced immediately after use. In general, the sanitary napkin has to be used for about 3 to 7 days every month, and since the period of use is about 40 years, there is a burden that the purchase cost of the sanitary napkin is quite high.

In order to solve this problem, a 'sanitary pad with easy replacement of the inlay (Republic of Korea Patent No. 10-1653190)' has been proposed in which an inner paper having menstrual blood absorption is coupled to the cover in a detachable structure. If the conventional dual structure sanitary napkin configured as described above is used, there is an advantage that the cover can be reused by replacing only the inner lining that has absorbed a certain amount of menstrual blood.

However, the conventional dual structure sanitary napkin has a disadvantage that menstrual blood may leak to the outside when the amount of menstruation exceeds the absorption amount of the inlay because menstrual blood is absorbed only in the inner lining and cannot be absorbed by the cover. In addition, it is convenient to wear a thin sanitary napkin when the menstrual amount is small. As mentioned above, the conventional dual-structure sanitary napkin cannot absorb menstrual blood, so the cover cannot be used alone without the inlay. There is also a disadvantage that an inlay must be attached to the cover before use.

In addition, the conventional dual structure sanitary napkin has a problem that the position of the inlay attached to the cover is moved or the inlay is curled when the user's amount of activity is high.

1 is a perspective view of a sanitary napkin having an inner pad according to the present invention, and FIG. 2 is an exploded perspective view of a sanitary napkin having an inner pad according to the present invention.

A sanitary napkin having an inner pad according to the present invention is a sanitary napkin having a dual structure so that the absorption power can be changed according to the amount of menstruation. It is composed of an inner pad 200 that is coupled in a possible structure.

The main pad 100 includes an absorbent body 110 having a function of absorbing menstrual blood, and a cover 120 surrounding the absorbent body 110, similarly to a generally used sanitary napkin, in the width direction of the cover 120 . Wings 122 for attachment may be provided on both sides. At this time, since the absorbent body 110 and the cover 120 are used in various materials and shapes even in the conventional sanitary napkin, a detailed description of the absorbent body 110 and the cover 120 will be omitted.

Meanwhile, in the sanitary napkin having an inner pad according to the present invention, the inner pad 200 is also made of a material having a function of absorbing menstrual blood. Accordingly, when the amount of menstruation is large, the user can absorb a greater amount of menstrual blood by attaching the inner pad 200 to the main pad 100 as shown in FIG. 1 . In this case, as the overall thickness of the sanitary napkin increases, the fit and breathability decrease, so that when the amount of menstruation is small, the user can use only the main pad 100 by removing the inner pad 200 .

As described above, the sanitary napkin having the inner pad according to the present invention can be used by attaching the inner pad 200 or by removing the inner pad 200 to use only the main pad 100, depending on the user's choice. It has the advantage of being very good. In addition, when menstrual blood is absorbed only in the inner pad 200 , only the inner pad 200 is replaced with a new one and the main pad 100 is reused, thereby preventing unnecessary waste of the sanitary napkin.

On the other hand, the inner pad 200 may be manufactured in the form of one pad as shown in this embodiment, or may be manufactured in the form of overlapping fabrics in several layers. That is, the inner pad 200 can be manufactured in any structure as long as it can be coupled to the main pad 100 in a detachable structure while having a function of absorbing menstrual blood.

A sanitary napkin having an inner pad according to the present invention may have a structure in which the inner pad 200 is attached to the main pad 100 with a Velcro tape so that the inner pad 200 can be easily attached and detached. .

For example, as shown in FIG. 2 , a sanitary napkin having an inner pad is provided with two or more male velcro tapes 210 on the bottom surface of the inner pad 200 , and the male velcro tape 210 is provided on the upper surface of the cover 120 . An arm velcro tape 124 may be provided at a point corresponding to the tape 210 . As such, when the inner pad 200 is configured to be attached to the main pad 100 by the male Velcro tape 210 and the female Velcro tape 124 , the user places the inner pad 200 on the main pad 100 . Since the inner pad 200 can be attached to the main pad 100 only by placing and pressing the inner pad 200 , and the inner pad 200 can be separated from the main pad 100 only by pulling the inner pad 200 . , it has the advantage of being very easy to use.

At this time, the male velcro tape 210 may be provided on the cover 120 of the main pad 100 and the female velcro tape 124 may be provided on the bottom surface of the inner pad 200 , but in this way, the male velcro tape 210 . is provided on the cover 120 of the main pad 100, when the inner pad 200 is removed and only the main pad 100 is used, the velcro tape 210 may stimulate the user's skin. Therefore, the male Velcro tape 210 is preferably provided on the bottom surface of the inner pad 200 as shown in this embodiment.

3 is an exploded perspective view of a second embodiment of a sanitary napkin having an inner pad according to the present invention, and FIG. 4 is an inner pad 200 and an elastic piece ( 300) is a cross-sectional view showing the coupling structure, and FIG. 5 is a cross-sectional view of the second embodiment of the sanitary napkin having an inner pad according to the present invention.

When the inner pad 200 is configured to be detachably attached to the main pad 100 by the male Velcro tape 210 and the female Velcro tape 124 as in the embodiment shown in FIGS. 1 and 2, the main pad 100 When using this alone, the arm velcro tape 124 may come into contact with the user's skin and feel uncomfortable.

The sanitary napkin having an inner pad according to the present invention may be configured such that the inner pad 200 is detachably attached to the main pad 100 even if a separate attachment means is not provided on the cover 120 of the main pad 100 . have.

For example, as shown in FIG. 3 , a sanitary napkin having an inner pad according to the present invention has a cut-out line 126 on the upper surface of the cover 120 at a point corresponding to both ends of the inner pad 200 in the longitudinal direction. An elastic piece 300 integrally coupled to the inner pad 200 may be additionally formed so that both ends in the longitudinal direction are inserted between the absorbent body 110 and the cover 120 through the cut-out line 126 . can

At this time, the elastic piece 300 is made of a material having a restoring elasticity and is formed in the shape of a bar plate extending long in the longitudinal direction of the main pad 100, as shown in FIG. 4(b). As shown in FIG. 4 ( a ), when the user's force is released after being bent by the user's force, it can be restored to its original state. Therefore, the user inserts both ends of the elastic piece 300 in the longitudinal direction into the cut line 126 in the bent state of the inner pad 200 and the elastic piece 300 as shown in FIG. 4(b), respectively. , by releasing the force bending the inner pad 200 and the elastic piece 300 , the inner pad 200 can be coupled to the main pad 100 as shown in FIG. 5 .

As such, when the inner pad 200 is configured to be coupled to the main pad 100 by the elastic piece 300 , the cover 120 of the main pad 100 is provided with a separate configuration such as an arm velcro tape 124 . Since there is no need to be additionally coupled, there is an advantage in that the user does not feel discomfort when wearing the main pad 100 alone.

On the other hand, since the inner pad 200 is smaller in size than the main pad 100 and is in direct contact with the user's genitals, it can be rolled or bent to form a cylindrical shape when the user moves or exercises excessively. have. As described above, when the inner pad 200 is deformed or bent, menstrual blood cannot be absorbed into the inner pad 200 and leaking may occur.

At this time, the elastic piece 300 attached to the inner pad 200 not only serves to couple the inner pad 200 to the main pad 100 , but also prevents the inner pad 200 from being rolled or bent. That is, it also serves to support the shape of the inner pad 200 in its original state. Therefore, when the elastic piece 300 is integrally coupled to the inner pad 200 as in the present embodiment, the inner pad 200 rotates even if the user performs an aggressive motion or exercise while wearing the sanitary napkin according to the present invention. It is possible to stably maintain a state in close contact with the user's genitalia without being dried or bent, and there is an advantage in that it is possible to prevent the leakage of menstrual blood.

In order for the elastic piece 300 to fully support the shape of the inner pad 200 , the elastic piece 300 is preferably coupled to penetrate the inner pad 200 . However, when the elastic piece 300 is coupled to pass through the inner pad 200 , when the end of the elastic piece 300 is inserted through the incision line 126 , as shown in FIG. 5 , the absorber 110 and the elasticity Since a large space is generated between the pieces 300 , there is a fear that the fixing force of the inner pad 200 may be slightly lowered. Accordingly, the elastic piece 300 may be coupled to be attached to the bottom surface of the inner pad 200 . That is, the structure in which the elastic piece 300 is coupled to the inner pad 200 may be variously changed and applied according to the selection of the manufacturer.

6 is an enlarged cross-sectional view of the elastic piece 300 included in the third embodiment of the sanitary napkin having an inner pad according to the present invention.

The elastic piece 300 may be made of plastic so as to have a certain level of bending strength or higher while having an elastic restoring force. As such, when the elastic piece 300 is made of plastic, the frictional force between the absorbent body 110 and the cover 120 is very low, so even if a small external force is applied to the elastic piece 300, the elastic piece 300 is 126) may occur.

In order to prevent the elastic piece 300 from easily coming out of the incision line 126 as described above, a plurality of locking projections are formed at a portion of the elastic piece 300 that is inserted into the main pad 100 through the incision line 126 . 310 may be formed. At this time, when the locking protrusion 310 is formed up to the upper surface of the elastic piece 300, the locking protrusion 310 may penetrate the cover 120 and stimulate the user's skin, so the locking projection 310 is this As shown in the embodiment, it is preferable that the elastic piece 300 is formed on a bottom surface of a portion inserted into the main pad 100 through the cut-out line 126 .

In addition, in the sanitary napkin having an inner pad according to the present invention, when the elastic piece 300 is moved in the direction in which the incision line 126 is inserted, the locking protrusion 310 does not interfere with the movement of the elastic piece 300 . No, when the elastic piece 300 moves in a direction away from the incision line 126 , it is preferable that the locking protrusion 310 inhibits the movement of the elastic piece 300 .

That is, the locking protrusion 310 is formed with a sharp end, and the end of the elastic piece 300 protrudes obliquely toward the opposite direction (right direction in FIG. 6) of the direction in which the end is inserted into the incision line 126. desirable. When the locking protrusion 310 protrudes obliquely in this way, the inner pad 200 can be easily attached to the main pad 100 because the elastic piece 300 is gently inserted when the incision line 126 is inserted, The elastic piece 300 inserted into the incision line 126 is fixed by the locking protrusion 310 on the upper surface of the absorber 110, so that the inner pad 200 is detached against the user's intention. The advantage is that it does not. In this case, the shape and number of the locking protrusions 310 may be variously changed according to the designer's selection.

Meanwhile, the inner pad 200 may be made of a cotton material, that is, a cotton fabric. This is because the absorbency is excellent, ventilation is easy, and it is harmless to the human body, and it can be washed and reused semi-permanently. Conventional simple cotton sanitary napkins have a lower cover composed of a waterproof layer, so it is difficult to use a washing machine and a dryer, so washing by hand and then naturally drying is not good, but the inner pad 200 of the present invention does not have a separate waterproof layer, It has the advantage of being easy to wash because it is possible to use a washing machine and a dryer.

In addition, when the main pad 100 of the present invention is composed of a cotton sanitary napkin and the inner pad 200 is made of a cotton material, both the main pad 100 and the inner pad 200 can be reused to prevent environmental pollution. The main pad 100, which should be hand-washed and naturally dried due to the lower cover 120 as a waterproof layer, is replaced only once a day, so the washing convenience can also be improved.

In addition, when the inner pad 200 made of a cotton material is added to the conventional disposable sanitary napkin, there is an advantage in that the pain of the sensitive part due to the existing sanitary napkin is alleviated.

In addition, the inner pad 200 may be a cotton fabric including a cooling composition. That is, when wearing a sanitary napkin in hot summer, discomfort increases, as well as bacteria breed and the smell of menstrual blood can be emitted. By doing so, these shortcomings can be improved.

In the present invention, as the cooling composition, a composition consisting of 20 to 40% by weight of xylitol, 2 to 10% by weight of citric acid, 0.1 to 0.5% by weight of chitosan, 0.1 to 0.5% by weight of menthol and the remainder of distilled water may be used, and a small amount as needed of surfactants can also be used. Such a cooling composition has advantages of excellent cooling effect, excellent antibacterial and deodorizing properties, and excellent washing durability.

In the present invention, the method of picking up the cooling composition on the cotton fabric may use a method of absorbing moisture during the padding process, but the method is not limited, and the manufactured inner pad 200 is immersed in the cooling composition and then dried and dried. can also be used.

As mentioned above, although the present invention has been described in detail using preferred embodiments, the scope of the present invention is not limited to specific embodiments, and should be interpreted by the appended claims. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
