Description

{Cotton Sanitary Napkin}

The present invention relates to a sanitary napkin.

In general, all fertile women from menarche to menopause use a pad-type sanitary napkin that attaches to the inside of the panties during repetitive menstrual cycles to absorb physiological fluid such as menstrual blood. Such sanitary napkins use chemical agents for rapid absorption and suppression of smell. For example, the menstrual-absorbing cover is polyvinyl-based, and as described in the patent documents of the following prior art documents, a cotton in the sanitary napkin is provided with an absorbent core containing polyacrylate, which is a chemical product in the form of an algae. Such polyacrylates are inexpensive and easy to manufacture, and are widely used chemicals. In the disposable diapers and disposable sanitary napkins, about 90,000 tons are consumed annually. However, since polyacrylates are not biodegradable and do not permanently decay, a great amount of polyacrylates are disposed of at landfills, which causes environmental pollution. In recent years, chemical dyes have been proved to be harmful to the human body. Some of the disposable sanitary napkins have been subjected to dyeing treatment, resulting in problems such as heat due to chemical dyeing, skin rashes, and itching.

In order to solve the above-mentioned problem, a cotton sanitary napkin which is a natural material which can be recycled while preventing skin diseases, unpleasant smell, and the like is used. However, there is a problem that the sanitary napkin according to the related art is exhausted when worn or a mark is formed outside the clothes. In addition, the conventional sanitary napkin has a limitation in completely absorbing the menstrual fluid, and there is a problem that the menstrual fluid leaks. Of course, it is possible to cope with the problem of leakage of the menstrual fluid by using the one-piece sanitary napkin which is made by stacking the multiple napkin sanitary napkins at a time. However, since the single-piece sanitary napkin is overlapped with the multiple layers of fibers in the washing and drying process, There is a problem that the bacteria can propagate in the semi-dry state.

FIGS. 4A to 4C are plan views illustrating a folding process of the absorbent unit of the facial sanitary napkin according to the first preferred embodiment of the present invention. FIG.

1 to 4, the napkin 100 according to the present embodiment includes a central portion 111, a first extending portion 113 extending upward from the upper end of the central portion 111, The first extending portion 113 and the second extending portion 115 each have a width wider than the center portion 111 as the distance from the central portion 111 increases A cover part 121 into which the absorbing part 110 is inserted, and a cover part 121 (not shown) which folds and folds on two reference lines 117 extending in the up and down direction so as to overlap with each other, And a wing portion 123 protruding in the left-right direction of the main body 120. The wing portion 123 engages the main body 120 with the undergarment.

The absorber 110 absorbs the physiological fluid and may be made of a surface component. Here, the absorbing portion 110 is folded on the basis of two fine lines 117 extending in the vertical direction. Therefore, since the absorbent portion 110 is overlapped in three layers as a whole, the physiological fluid can be sufficiently absorbed, and the physiological fluid can be prevented from leaking. However, the upper end 113a and the lower end 115a of the absorbing part 110 are kept in a single layer, not all of the absorbing part 110 is folded into three folds. This is because of the shape of the absorber 110 itself and will be described in detail as follows.

3, the absorption portion 110 may include a central portion 111, a first extension portion 113, and a second extension portion 115. [ The first extending portion 113 extends upward from the upper end of the center portion 111 and the second extending portion 115 extends from the upper end of the center portion 111 to the center portion 111. The center portion 111 is located at the center of the absorbing portion 110, And extends from the lower end to the lower side. At this time, the widths of the first extension portion 113 and the second extension portion 115 become narrower than the center portion 111 as the distance from the center portion 111 increases. The upper end 113a of the first extending portion 113 and the lower end 115a of the second extending portion 115 are folded one by one when the absorbing portion 110 is folded with respect to the two fine lines 117, ≪ / RTI > As a result, since the upper end 113a and the lower end 115a of the absorbing portion 110 are held in a single ply, it is possible to prevent a mark from being generated outside the clothes without being exhausted when worn.

Here, the overall shape of the absorbing part 110 is not particularly limited, but may be formed in a hexagonal shape (for example, a regular hexagon) as shown in Figs. 4A to 4C. In this case, the center portion 111 may be a rectangle connecting four vertexes of a regular hexagon, and the first and second extension portions 113 and 115 may be triangular shapes arranged on the upper and lower sides of the rectangle, . Therefore, when the hexagonal absorbing portion 110 is folded with reference to the two fine lines 117 (see Figs. 4B to 4C), the rectangular central portion 111 and the first and second extension portions 113 and 115 May be overlapped in three layers. As a result, since the rectangular center portion 111 and the triangular first and second extension portions 113 and 115 are overlapped with each other in three layers, the physiological fluid can be sufficiently absorbed and the physiological fluid can be prevented from leaking. In addition, since the absorbing part 110 overlapped with three layers can be spread in a single layer, it is possible to wash more easily and easily, and also to check whether the menstrual blood has been completely removed, thereby preventing the risk of bacterial propagation. In addition, since the absorbing portion 110 overlapped with three layers can be spread in one layer, it can be dried quickly, thereby enhancing the sanitary property. In addition, the upper end 113a of the first extended portion 113, which is a triangle, and the lower end 115a of the second extended portion 115, which is a triangle, can be held in one layer. As a result, since the upper end 113a of the first extended portion 113 as a triangle and the lower end 115a of the second extended portion 115 as a triangle are held as a single layer, .

1 to 3, the main body 120 serves to receive and fix the absorber 110 to the undergarment, and can be made of a surface component and a waterproof cloth component (see, for example, The main body 120 may be manufactured by padding a waterproof cloth component in the surface component). Here, the main body 120 includes a cover portion 121 and a wing portion 123. At this time, the cover part 121 may be composed of the base part 125 and the opening / closing part 127, into which the absorption part 110 is inserted. Specifically, the base portion 125 and the opening / closing portion 127 are formed to have the same overall shape so that the rim can be coupled to each other through sewing or the like. In the space between the base portion 125 and the opening / closing portion 127, 110 may be accommodated. Further, the absorbing portion 110 can be inserted or removed through the opening / closing portion 127. The opening and closing part 127 may include a first opening and closing part 128 having a first rim 128a opened and a second opening and closing part 129 having a second rim 129a opened. At this time, the second rim 129a of the second opening and closing part 129 is covered with the first opening and closing part 128. The user then opens the first rim 128a of the first opening and closing part 128 and then opens the second rim 129a of the second opening and closing part 129 to insert the absorbing part 110 into the main body 120 (See FIG. 3), and the absorber 110 can be removed through an opposite process. At this time, the first opening / closing part 128 and the second opening / closing part 129 are arranged to overlap with each other in a predetermined area (refer to FIG. 1), so that the absorption part 110 can be prevented from being separated from the body 120.

The wing portion 123 of the main body 120 protrudes in the left and right direction of the cover portion 121. Here, the wing portion 123 is provided with fastening means 130 such as a button. Accordingly, the wing portions 123 can be fastened to each other through the fastening means 130 in the state of surrounding the undergarment. As described above, when the wing portion 123 is fastened, the main body 120 can be coupled to the undergarment. At this time, the main body 120 can be coupled to the underwear such that the base portion 125 faces upward and the opening / closing portion 127 faces downward. Thus, the base portion 125 can be brought into contact with the human body, and the opening / closing portion 127 can be brought into contact with the undergarment.

FIG. 5 is a perspective view of a facial sanitary napkin according to a second embodiment of the present invention, FIG. 6 is an exploded perspective view of a facial sanitary napkin according to a second embodiment of the present invention, FIGS. 7a to 7c are cross- FIG. 2 is a plan view showing the folding process of the absorbent portion of the face cloth according to FIG.

5 to 7, the surface napkin 200 according to the present embodiment has a longer length in the left-right direction than a length in the up-and-down direction and a narrower width toward the upper end 215a and the lower end 215b, A first folding line 213a and a second folding line 213b are folded on the basis of the first and second fine lines 213a and 213b extending in the up and down direction so that the area 211 is overlapped in three layers, And the center region 211 is disposed between the absorbent portion 210 and the undergarment so that at least two layers are fixed to each other and the central region 211 is folded The left end 217a and the right end 217b of the absorbing portion 210 are protruded from the central region 211 to absorb the absorbing portion 210 in the undergarment 210. [ Lt; / RTI >

The absorber 210 absorbs the physiological fluid and may be made of a surface component. Here, the absorbing portion 210 is folded on the basis of the first fine line 213a extending in the vertical direction and the second fine line 213b. At this time, the absorbing portion 210 is opposite in the direction of folding at the first trimming line 213a and the direction of folding at the second trimming line 213b. Therefore, since the central region 211 is overlapped with three layers in the absorbent portion 210, the physiological fluid can be sufficiently absorbed, and the physiological fluid can be prevented from leaking. However, not all portions of the absorbing portion 210 are folded into three folds. The left end 217a and the right end 217b protrude from the central region 211 and hold one layer because the length in the left and right direction is longer than the length in the up and down direction of the absorption portion 210. [ The left end 217a and the right end 217b of the absorber 210 are provided with fastening means 240 such as a button. Therefore, the left end 217a and the right end 217b of the absorbent 210 can be fastened to each other through the fastening means 240 in the state of surrounding the undergarment. Thus, when the left end 217a and the right end 217b of the absorbing portion 210 are fastened to each other, the absorbing portion 210 can be coupled to the undergarment. The absorbing portion 210 is narrowed toward the upper end 215a and the lower end 215b so that when the absorbing portion 210 is folded on the basis of the first and second fine lines 213a and 213b , And the upper end 215a and the lower end 215b of the absorbing portion 210 are also kept in one layer. As a result, since the upper end 215a and the lower end 215b of the absorbing portion 210 are held in a single layer, it is possible to prevent the occurrence of marks on the outside of the clothes without being exhausted when worn.

Here, the overall shape of the absorbing part 210 is not particularly limited, but may be formed as an overall ellipse (or a rounded rectangle) as shown in FIGS. 7A to 7C. In this case, since the elliptical absorption part 210 becomes narrower toward the upper end 215a and the lower end 215b, when the first and second fine lines 213a and 213b are folded on the basis of the first and second fine lines 213a and 213b (The central region 211 of the absorbing portion 210) between the first and second fine lines 213a and 213b, but the upper portion of the absorbing portion 210 215a and the lower end 215b may be held in a single layer. As a result, the central region 211 of the elliptical absorption portion 210 is overlapped with three layers, so that the physiological fluid can be sufficiently absorbed, and the physiological fluid can be prevented from leaking. In addition, since the absorbing part 210 overlapped with three layers can be spread in one layer, it is possible to wash more easily and easily, as well as to confirm that the menstrual blood has been completely removed, thereby preventing the risk of bacterial propagation. In addition, since the absorbent portion 210 overlapped with three layers can be spread in one layer, it can be dried quickly, thereby enhancing the sanitary property. In addition, since the upper end 215a and the lower end 215b of the absorbing part 210, which is an elliptical shape, are held in a single layer, it is possible to prevent a mark from being generated outside the clothes without being exhausted when worn. On the other hand, since the elliptic absorber 210 has a longer length than the length in the up-and-down direction, the lengths of the first and second finishing lines 213a and 213b (the left end 217a ) And the right end 217b). The left end 217a and the right end 217b of the absorptive portion 210 can be fastened to each other through the fastening means 240 in a state of surrounding the undergarment.

In addition, as shown in FIG. 8A, the elliptical absorbing portion 210 may extend longer to the lower end 215b than the upper end 215a. That is, the center of the absorption part 210, which is an elliptical shape, can be formed at a lower position. (The side of the lower end 215b of the absorbing part 210) than the front part (the upper end 215a side of the absorbing part 210) in many cases. In order to prevent this, the lower end 215b of the elliptical absorbing part 210 may be longer than the upper end 215a.

8B, the absorber 210 is formed in an elliptical shape, and includes an elliptical portion 219a formed in an elliptical shape, and first and second projections 219a and 219b projecting upward and downward from the elliptical portion 219a, respectively. (219b, 219c). That is, the absorbing part 210 is basically formed in an elliptical shape (the elliptical part 219a), and the first projecting part 219b protrudes upward and the second protruding part 219c protrudes downward, . ≪ / RTI > Further, when there is a large amount of menstrual fluid, it often leaks to the rear portion (on the side of the second projection 219c) than the front portion (the first projection 219b side). In order to prevent this, the second projecting portion 219c may protrude longer than the first projecting portion 219b.

In addition to the elliptical shape, the absorption portion 210 may be formed in a hexagon, as shown in Fig. 8C, or may be formed in rhombus, as shown in Fig. 8D.

7C, since the absorbing part 210 is coupled to the underwear through the fastening means 240 provided at the left end 217a and the right end 217b of the absorbing part 210, the absorbing part 210 ) Is applied with a pulling force to the left and right. Even if this force is applied, the central region 211 of the absorbing portion 210 should be kept in three layers. Therefore, at least two of the central regions 211 of the three-folded absorbent portion 210 can be fixed to each other. At this time, the means for fixing at least two layers of the central region 211 of the absorbent portion 210 is not particularly limited, but may be a sewing 214, a velcro, a button, or the like.

5 to 6, the main body 220 is disposed between the absorbent portion 210 and the undergarment and functions to cover the central region 211 of the absorbent portion 210, And a waterproof cloth component. Here, the main body 220 may include a cover portion 221 and a wing portion 223. At this time, the cover part 221 covers the central area 211 of the absorbing part 210 and the wing part 223 protrudes in the left and right direction of the cover part 221 to prevent the menstrual fluid from leaking in the left and right direction .

The main body 220 may be coupled to the undergarment together with the absorbent portion 210 through the fastening means 240 provided at the left end 217a and the right end 217b of the absorbent 210. [ At this time, the absorbent unit 210 is in direct contact with the human body, but the body 220 is not in direct contact with the human body. Therefore, since the absorbent unit 210 absorbs most of the menstrual fluid, the main body 220 can be used many times without replacing the absorbent unit 210 while replacing the absorbent unit 210 alone.

 FIG. 9 is an exploded perspective view of a surface sanitary napkin according to a third embodiment of the present invention, and FIG. 10 is a perspective view of a sanitary napkin to which a supplemental absorbent member according to a third embodiment of the present invention is added, 6 is a plan view showing the folding process of the auxiliary absorbent portion of the facial sanitary napkin according to the third embodiment of the present invention.

As shown in FIGS. 9 to 11, the facial sanitary napkin 200 according to the present embodiment can perform the function of an evening napkin by adding the auxiliary absorbent portion 230. Specifically, the auxiliary absorbing portion 230 may be made of a surface component so as to absorb the physiological fluid similarly to the absorbing portion 210, and may be overlapped with three layers (see FIG. 9). As described above, one end 233 of the auxiliary absorbing portion 230 overlapped with three layers can be inserted between two of the absorbing portions 210. Particularly, the auxiliary absorbing portion 230 can be inserted at the lower end 215b side of the absorbing portion 210 (refer to FIG. 10) to perform the function of actually extending the lower end 215b of the absorbing portion 210 have. The auxiliary absorbing portion 230 is formed so that the width of the other end 235 is wider than the width of the one end 233 inserted into the absorbing portion 210 to prevent the auxiliary absorbing portion 230 from leaking even when there are many menstrual fluids. At this time, although the shape of the auxiliary absorbing portion 230 is not particularly limited, as shown in FIG. 11, the auxiliary absorbing portion 230 may be formed in a shape in which a sector 230b having a relatively small radius is removed from a sector 230a having a relatively large radius (At this time, the two bodies are center-aligned). When the auxiliary absorbing portion 230 is formed in this shape and then folded on the basis of the boundary line of the third equal portion, all portions of the auxiliary absorbing portion 230 can be overlapped in three layers.

On the other hand, as shown in Figs. 9 to 10, in order to cover the auxiliary absorbing portion 230, the cover portion 221 can be extended. That is, the cover part 221 can be enlarged to cover both the absorption part 210 and the auxiliary absorption part 230.

FIG. 12 is a perspective view of a facial sanitary napkin according to a fourth embodiment of the present invention, FIG. 13 is an exploded perspective view of a facial sanitary napkin according to a fourth embodiment of the present invention, FIGS. 14A to 14C are cross- FIG. 2 is a plan view showing the folding process of the absorbent portion of the face cloth according to FIG.

12 to 14, the surface napkin 300 according to the present embodiment includes a first finishing line 213a extending in the vertical direction and a second finishing line 213b extending in the vertical direction so that the central region 211 is overlapped in three layers. The absorbent part 210 is folded on the basis of the correcting line 213b and the folding direction at the first delineating line 213a is the same as the direction of folding at the second delineating line 213b. A second wing portion 260 coupled to the first wing portion 250 and the second wedge line 213b and a cover portion 221 disposed between the absorbent portion 210 and the undergarment and covering the center region 211, And the first wing portion 250 and the second wing portion 260 protrude from the central region 211 to couple the absorbing portion 210 to the undergarment.

The absorber 210 absorbs the physiological fluid and may be made of a surface component. Here, the absorbing portion 210 is folded on the basis of the first fine line 213a extending in the vertical direction and the second fine line 213b. At this time, the absorbing portion 210 has the same direction as the folding direction at the first trimming line 213a and the folding direction at the second trimming line 213b. Therefore, since the central region 211 is overlapped with three layers in the absorbent portion 210, the physiological fluid can be sufficiently absorbed, and the physiological fluid can be prevented from leaking. However, not all portions of the absorbing portion 210 are folded into three folds. For example, if the absorption part 210 becomes narrower toward the upper end 215a and the lower end 215b, the absorption part 210 may be separated from the first and second fine lines 213a and 213b The upper end 215a and the lower end 215b of the absorbing portion 210 can be kept in a single layer. As a result, since the upper end 215a and the lower end 215b of the absorbing portion 210 are held in a single layer, it is possible to prevent the occurrence of marks on the outside of the clothes without being exhausted when worn.

Here, the overall shape of the absorbing part 210 is not particularly limited, but may be formed as an overall ellipse (or a rounded rectangle) as shown in Figs. 14A to 14C. At this time, since the absorption part 210, which is an elliptic shape, becomes narrower toward the upper end 215a and the lower end 215b, when the first and second fine lines 213a and 213b are folded with reference to (The central region 211 of the absorbing portion 210) between the first and second finishing lines 213a and 213b, but the upper end of the absorbing portion 210 215a and the lower end 215b may be held in a single layer. As a result, the central region 211 of the elliptical absorption portion 210 is overlapped with three layers, so that the physiological fluid can be sufficiently absorbed, and the physiological fluid can be prevented from leaking. In addition, since the absorbing part 210 overlapped with three layers can be spread in one layer, it is possible to wash more easily and easily, as well as to confirm that the menstrual blood has been completely removed, thereby preventing the risk of bacterial propagation. In addition, since the absorbent portion 210 overlapped with three layers can be spread in one layer, it can be dried quickly, thereby enhancing the sanitary property. In addition, since the upper end 215a and the lower end 215b of the absorbing part 210, which is an elliptical shape, are held in a single layer, it is possible to prevent a mark from being generated outside the clothes without being exhausted when worn.

In addition, as shown in FIG. 15A, the absorption portion 210, which is an elliptical shape, may extend longer to the lower end 215b than the upper end 215a. That is, the center of the absorption part 210, which is an elliptical shape, can be formed at a lower position. (The side of the lower end 215b of the absorbing part 210) than the front part (the upper end 215a side of the absorbing part 210) in many cases. In order to prevent this, the lower end 215b of the elliptical absorbing part 210 may be longer than the upper end 215a.

15B, the absorber 210 is formed in an elliptical shape, and includes an elliptical portion 219a formed in an elliptical shape, and first and second projections 219a and 219b projecting upward and downward from the elliptical portion 219a, respectively. (219b, 219c). That is, the absorbing part 210 is basically formed in an elliptical shape (the elliptical part 219a), and the first projecting part 219b protrudes upward and the second protruding part 219c protrudes downward, . ≪ / RTI > Further, when there is a large amount of menstrual fluid, it often leaks to the rear portion (on the side of the second projection 219c) than the front portion (the first projection 219b side). In order to prevent this, the second projecting portion 219c may protrude longer than the first projecting portion 219b.

In addition to the elliptical shape, the absorption portion 210 may be formed in a hexagon, as shown in Fig. 15C, or may be formed in rhombus, as shown in Fig. 15D.

The first and second wing portions 250 and 260 serve to couple the absorbing portion 210 to the undergarment (see FIGS. 12 to 13). Here, the first wing portion 250 is coupled to the first finishing line 213a, and the second wing portion 260 is coupled to the second finishing line 213b. Therefore, if the central region 211 of the absorbing portion 210 is folded so as to overlap three folds with respect to the first and second fine lines 213a and 213b, the first wing portion 250 and the second The wing portion 260 protrudes from the central region 211. The first wing part 250 and the second wing part 260 are provided with fastening means 240 such as a button. As a result, the first wing portion 250 and the second wing portion 260 can be fastened to each other through the fastening means 240 in the state of surrounding the underwear. As described above, when the first wing portion 250 and the second wing portion 260 are fastened to each other, the absorbing portion 210 can be coupled to the undergarment.

The main body 220 is disposed between the absorbent part 210 and the undergarment and functions to cover the central area 211 of the absorbent part 210 and can be made of a surface component and a waterproof cloth component. Here, the main body 220 may include a cover portion 221 and a wing portion 223. At this time, the cover part 221 covers the central area 211 of the absorbing part 210 and the wing part 223 protrudes in the left and right direction of the cover part 221 to prevent the menstrual fluid from leaking in the left and right direction .

The main body 220 may be coupled to the undergarment together with the absorbent portion 210 through the fastening means 240 provided on the first and second wing portions 250 and 260. At this time, the absorbent unit 210 is in direct contact with the human body, but the body 220 is not in direct contact with the human body. Therefore, since the absorbent unit 210 absorbs most of the menstrual fluid, the main body 220 can be used many times without replacing the absorbent unit 210 while replacing the absorbent unit 210 alone.

FIG. 16 is an exploded perspective view of a surface sanitary napkin according to a fourth embodiment of the present invention, FIG. 17 is a perspective view of a surface sanitary napkin to which a supplementary absorbent member according to a fourth embodiment of the present invention is added, 7 is a plan view showing a folding process of the auxiliary absorbent portion of the face napkin according to the fourth embodiment of the present invention.

16 to 18, the facial sanitary napkin 300 according to the present embodiment can perform the function of an evening napkin by adding the auxiliary absorbent portion 230. [ Specifically, the auxiliary absorbing portion 230 may be made of a surface component so as to absorb the physiological fluid similarly to the absorbing portion 210, and may be overlapped with three layers (see FIG. 16). As described above, one end 233 of the auxiliary absorbing portion 230 overlapped with three layers can be inserted between two of the absorbing portions 210. Particularly, the auxiliary absorbing portion 230 can be inserted at the lower end 215b side of the absorbing portion 210 (see FIG. 17) to perform the function of actually extending the lower end 215b of the absorbing portion 210 have. The auxiliary absorbing portion 230 is formed so that the width of the other end 235 is wider than the width of the one end 233 inserted into the absorbing portion 210 to prevent the auxiliary absorbing portion 230 from leaking even when there are many menstrual fluids. At this time, although the shape of the auxiliary absorbing portion 230 is not particularly limited, as shown in FIG. 18, the shape of the auxiliary absorbing portion 230 may be formed by removing the fan-shaped portion 230b having a relatively small radius from the relatively large- (At this time, the two bodies are center-aligned). When the auxiliary absorbing portion 230 is formed in this shape and then folded on the basis of the boundary line of the third equal portion, all portions of the auxiliary absorbing portion 230 can be overlapped in three layers.

On the other hand, as shown in Figs. 16 to 17, in order to cover the auxiliary absorbing portion 230, the cover portion 221 can be extended. That is, the cover part 221 can be enlarged to cover both the absorption part 210 and the auxiliary absorption part 230.

19A to 19B are perspective views of a facial sanitary napkin to which an additional absorbent portion according to a fifth embodiment of the present invention is added, and Fig. 20 is a cross-sectional view of a napkin of the facial sanitary napkin according to the fifth embodiment of the present invention FIG.

As shown in Figs. 19 to 20, the facial sanitary napkin 300 according to the present embodiment can be used even when there is a large amount of menstrual blood, by adding the additional absorbent portion 270. Fig. Specifically, the additional absorbing portion 270 may be made of a surface component so as to absorb the physiological fluid similarly to the absorbing portion 210. At this time, the additional absorbing portion 270 may be arranged to be folded or folded (see FIG. 20) and surrounded by the absorbing portion 210 which is overlapped with three layers (see FIG. 19A). If the additional absorbing portion 270 is disposed so as to surround the absorbing portion 210 as described above, even if there is a large amount of menstrual blood due to the absorbing power of the additional absorbing portion 270, it can be absorbed. In addition, since the additional absorbing portion 270 is provided separately from the absorbing portion 210, it is possible to more easily and easily wash the skin, and it is possible to confirm that the menstrual blood has been completely removed, thereby preventing the risk of bacterial growth. In addition, since the additional absorbing portion 270 can be opened or folded, the absorbing portion 110 overlapped in three layers can be spread in one layer, so that it can be dried quickly, thereby enhancing the sanitary property.

However, the additional absorbing portion 270 is not necessarily disposed so as to be surrounded by the three-folded absorbing portion 210, and the additional absorbing portion 270 may be formed on the absorbing portion 210 As shown in FIG.

20, the additional absorbent portion 270 may be arranged so as to be surrounded by the absorbent portion 210, which is formed in a hexagonal shape and folded in half, folded or folded in three layers, have.
