Description

  The present invention relates to a sanitary article that prevents menstrual blood leakage during menstruation and suppresses the spread of menstrual blood.

  As a conventional feminine sanitary product, a napkin that has a length from a female genital to a buttock and attaches most of its bottom surface to underwear is generally used.

  In order to prevent leakage of menstrual blood from the napkin to underwear, there are conventional napkins that are partially widened to prevent leakage from the side and thin walls on the side. In addition, in order to prevent leakage from behind while sleeping, there are some that widen the buttock side or have a hill shape around the bottom of the butt so that menstrual blood does not flow backwards. Furthermore, as a result of being wide, there is a diaper type, but it is bulky and costly, has many wasted parts, and is hardly spread.

  As a measure to suppress the spread of menstrual blood on the napkin, a material that absorbs liquid quickly called an absorbent sheet is used, but when a person gets up, suddenly a lot of menstrual blood On the other hand, it takes some time for the napkin to absorb the liquid, so it is not so effective because it cannot catch up with the rapid menstrual momentum. In addition, as the body moves, the napkin is deformed and menstrual blood does not always get on the absorbent sheet. The fact that we have to take the measures described above despite having an absorbent sheet confirms that it is not very effective. Another measure to prevent the spread of menstrual blood is to apply stitches, and when pressure is applied from both sides, the inside of the stitch swells so that it adheres to the body and increases the spread of menstrual blood. It is something to suppress. However, in fact, even if the inside of the stitch rises due to the pressure of the thigh, the outside is often higher than that, so menstrual blood will also be attached to the outside of the stitch, and it will adhere to the body It's hard to say and not very effective.

  As another sanitary product, there is a so-called tampon that inserts a material that absorbs rod-shaped menstrual blood directly into the vagina, but there is a resistance to the act of inserting it directly into the vagina, and forget it while it is inserted There is also anxiety that it will end up, and it is necessary to find the position of the vagina and it may not be inserted smoothly. When removing, the hands often become dirty with menstrual blood. For this reason, it is not as popular as napkins. Even when using a tampon, a napkin is generally used together. If the tampon exceeds the menstrual volume, the menstrual flow is the same as when using the napkin.

  In addition, the following patent document can be mentioned as a well-known technique relevant to this invention.

  JP-A-10-286278   Japanese Laid-Open Patent Publication No. 2002-17777   Japanese Laid-Open Patent Publication No. 2002-159534

  In the conventional sanitary products described above, the spread of menstrual blood cannot be suppressed, and measures are taken to prevent leakage, but the effect is not sufficient. It can be said that conventional napkins are not attached to the body. Since the bottom of the napkin is attached to the underwear as a whole and is integrated with the underwear, a shift occurs with respect to human movement, and menstrual blood is spread over a wide area of the napkin, causing leakage. A conventional napkin does not deviate from underwear, but deviates from the vagina. With conventional napkins, a space is always created between the vagina and the human movement.

  In addition, even if a part is made into a hilly shape, a stitch or a wall is provided to make it three-dimensional, it is not very effective because it is not attached to the body. Certainly, before being used, the ingenuity that has been applied is in its intended form. If you keep your legs open on a daily basis, or if the wearer moves and you simply apply pressure from the side, the device will serve your purpose well. However, in actual use, the crotch is almost always closed and the napkin is always under pressure from the side, and the movement of the back and forth and the left and right separately by walking is complicated. In other words, since the napkin is deformed from the time when the napkin is mounted, the device applied to the conventional napkin cannot exhibit a sufficient effect. For example, if thin walls are installed on both sides of the napkin to prevent side leakage, when pressure is applied from the side, how much stitching is applied, and the inside is raised by the pressure from the side. Even if you try to bring the vagina and napkin closer, the outside of the napkin is higher due to the pressure of the thigh, the vagina and the napkin are separated, and a thin wall is installed on the raised outside, and menstrual blood is actually above the thin wall Is often attached.

  Since the human body is recessed from the vagina to the buttocks, with conventional napkins, there is always a gap between the vagina and if the wearer is stationary upright, menstrual blood falls directly from the vagina, but the person moves As a result, menstrual blood flows freely through the gaps, soiling the napkin over a wide area, and menstrual blood is also attached around the vagina, causing discomfort. Furthermore, the deformation as described above is added, and menstrual blood is spread over a wide area and leaks.

  In addition, the conventional napkin may have a dust problem. Napkins that are dirty over a wide area are uncomfortable, so they must be replaced every time you go to the toilet. At that time, the state of the napkin is almost equal to the capacity to absorb the menstrual blood. It is not satisfied. Still, there is a sense of discomfort, so it is rarely used until the capacity is filled. Therefore, the conventional napkin is wasteful with respect to its size and places a considerable burden on the environment as garbage. Since many women use it, the amount of discarded napkin is considered to be enormous. It can be said that the larger the napkin, the more wasteful waste is said to prevent leakage.

  The sanitary products in Literatures 1 to 3 are sanitary products that close the gap between the napkin and the vagina and adhere to the body instead of underwear. Although not generally available, the following problems can be considered. First of all, the idea of attaching and fixing parts that are thought to use materials such as adhesives or materials that adhere to the skin is because the body is delicate during menstruation, There is a possibility of anxiety that the skin may be irritated by something like an agent, or a material that adheres to it, and there may be a sense of incongruity, which makes it a sense of resistance and seems generally unacceptable. Those with resistance are generally considered unacceptable because tampon is not so popular due to resistance in its usage.

  In addition, even if it is not attached to the skin by the method as described above, the length considered from Documents 1 and 2 is short and may not be able to cope with the front-back displacement, and may be attached or removed. Occasionally, menstrual blood is attached to the hand, making it harder to handle as well as tampon. In order to prevent the displacement before and after that, if it is attached to the skin and fixed, the above problem will occur again. Moreover, if it connects with the center of a napkin, even if it can be removed, menstrual blood will be attached to a hand. Saying that your hands are dirty is harder to handle than you might expect, and then, until you wash your hands, various things such as clothes, belongings, and doors get dirty. In addition, when the structure becomes complicated, it is difficult to manufacture, and costs are increased, making it difficult to use. The surface of the napkin after removal becomes painful, and it becomes tempting to replace the napkin, the meaning of removal is lost, and it may eventually become uneconomical.

  According to Documents 1 to 3, in particular, according to 1, if the shape of the cross section is easy to apply and does not leak, the shape of the elongated cross section is not particular, and it is easy to apply and difficult to leak, but underwear and napkins In the case where they are completely independent and are not fixed to the body, they are simply applied to the depressions. It is not sufficient that these elongated sanitary products are easy to apply and difficult to leak. In this form, there is anxiety that it is unstable and likely to come off. In that case, it is generally unacceptable. In these forms, it is considered that the roll will occur when the groove is removed. Even if the cross section is a triangle, square, or other polygon, once it is removed from the groove, it may roll due to human movement.

  In order to solve the above-mentioned problems, the sanitary product of the present invention is adapted to the movement of the body, efficiently absorbs menstrual blood, suppresses the spread of menstrual blood, has a stable shape, The purpose is to make the structure simple, industrially easy to use, and generally accepted.

  The sanitary product of the present invention that achieves the above-described object fills the groove of the buttocks from the female genitalia by sandwiching it in the groove of the crotch of the human body and makes it difficult to come off from the groove. Therefore, it is a sanitary product having a length from a female genital to a buttock in which a protruding portion fits into a groove of a crotch with a convex upper surface. With this length and shape, the vagina and the product of the present invention can be kept in close contact with each other without being attached to the skin. Further, the sanitary product is more difficult to come off by filling the groove of the buttocks from the female genital and forming the protruding portion so as to correspond to the depth of the groove as it goes to the buttocks side. In addition, in order to prevent these sanitary products from being greatly displaced back and forth, the sanitary products are curved so as to follow the crotch grooves.

  The above-described sanitary product of the present invention is manufactured in a flat state or a substantially flat state with a simpler structure, and is formed in a state of being folded in the center at the time of use. Can be formed in the shape of the above-mentioned sanitary products by the user opening the lower part that does not enter the front groove by himself / herself. He also invented a foldable sanitary product. In order to make it easy for the user to use, the folding type can be provided by folding the portion that becomes the protrusion in advance. At the time of manufacture, the protrusion formed when the sheet is folded in two can be curved to follow the crotch groove.

  The sanitary product of the present invention is mainly used independently from the body, napkin and underwear. The lower and back have a thin band that extends to the lower part of the waist so that one or both of its ends can be attached below the navel of the underwear or around the lower part of the waist Use things.

  The above-mentioned sanitary products are used mainly in combination with conventional napkins to achieve their purpose, but if you want to use them without using them together, make the bottom of the sanitary products of the present invention as wide as conventional napkins. The sanitary product of the present invention having a mountain shape in cross section that can be raised on both sides and the entire back surface can be attached to the underwear may be used. At this time, both sides should not be like the conventional thin wall of a napkin, but have a certain thickness, and the height should be higher than the central protrusion when pressure is applied from the side. Keep it up.

    By making it completely independent from underwear and napkins, it is possible to measure the integration with the human body, interlock with the movement of the body and keep the gap from the vagina to the buttocks filled, thus suppressing the spread of menstrual blood and leaking Can be prevented.

  Since the product of the present invention is sufficiently long from the vagina to the buttocks, even if the product of the present invention moves back and forth due to walking etc., the vagina will not be detached from the product of the present invention, and human movement The function is not impaired by this. In addition, since the buttock side is deeper than the depression on the female genital side, this length can be used to firmly clamp the product of the present invention on the buttock side and stabilize the front. As a result, the shift to the left and right is also prevented. Moreover, by having the length, even when removed, menstrual blood does not reach both the front and rear ends, and can be replaced without soiling the hands.

  The effect of having a lower portion that has a convex upper surface and serves as a base for the protruding portion will be described. The product of the present invention has a lower part that becomes a base having a certain thickness, and has a convex surface on the upper surface, thereby giving a sense of stability and making it difficult to come off from the groove. In addition, even when it is removed from the groove, it does not easily fall over, does not easily roll to the side, and does not easily shift to the left or right. If the foundation is too thin, it will be deformed by body pressure. If there is a certain amount of thickness, the deformation can be prevented, and even if it is deformed, the thickness and the width wider than the protruding portion have a synergistic effect, and the function is not impaired. If there is no base part and it is a simple elongated shape, even if the cross section is a circle, triangle, square, or other polygon, once it comes off the groove, it may roll due to human movement.

  In addition, by having a part that will serve as the foundation, even if a sudden large amount of menstrual blood due to standing up is not received by the protrusion due to its momentum and quantity, it will flow to the foundation part This reduces the spread of menstrual blood. Without that foundation, it can't be taken, and that amount of power will spread to the napkin. Not only is it easy to apply and not to leak as in the prior art, but it is also characterized by being difficult to come off and difficult to spread.

  Since it has a shape consisting of a base portion and a protruding portion, it is not only a simple elongated shape, but also follows the roundness of the collar including the groove as well as the groove. In other words, it fits the entire groove, so it can be said that it is difficult to slip. Since it is a sanitary product sandwiched in the groove, the function is not impaired by deformation due to pressure by the thigh. Can be used without resistance because it does not stick to the skin.

  The product of the present invention keeps the groove from the female genital to the buttocks filled with the synergistic effect due to the above length and shape, and can maintain close contact with the vagina without directly attaching the product of the present invention to the skin. It is.

  The effect of increasing the height of the protrusion as it goes backward will be described. Since the crotch groove of the human body is deeper on the buttocks side, by increasing the projection part accordingly, the area sandwiched by the groove increases accordingly, so it is difficult to come off the groove behind, As a result, it becomes more stable from the rear to the front. Because of its height, even if it tries to slip down, it hits underwear or a napkin and cannot stabilize, so it is stable. In this case, even if only the protruding portion is on the heel side, the area sandwiched by the groove is large, so that it is difficult to come off from the groove. Moreover, since the vagina is not near the upper part and menstrual blood does not come directly, in this case, the effect can be exhibited even if the buttock side has no foundation part.

  The effect by curving back and forth will be described. In order to attach more to the body, it is possible to prevent a large shift forward and backward due to walking or the like by adding curves to the front and rear. In addition, if it is curved, if it is a straight line, even if it is attached to the curve of the groove, if used independently, even if it is attached to the body at the time of wearing, the force to return to the straight line will then work , The front and back are easily separated from the groove, and the force works toward the underwear.In this case, if the underwear is solid, even if it is a straight line, it will be pressed against the underwear, so it will not return to a straight line at all, If the underwear is loose, it becomes unstable, and the front and rear are separated from the groove, and only a part of the elongated shape is caught in the groove, so that it is easy to come off. On the other hand, sticking to the skin is a resistance. If the point curve is made, it is possible to prevent the sanitary article of the present invention from naturally adhering to the groove and shifting. Although some conventional napkins are curved, the conventional napkins are not in close contact with the vagina.

  The effect of the foldable sanitary product of the present invention will be described. The foldable sanitary product of the present invention that can be manufactured and sold in a flat state or a substantially flat state is further simplified in structure compared to any of the sanitary products described above. Therefore, it is easy to manufacture and can be provided at low cost. In addition, it is flat and easy to carry. Although it may seem that there is the hassle of forming a convex shape on its own during use, it is believed that the advantage of this is greater. At the time of use, first, it is folded in half, and the resulting protrusion is sandwiched between the crotch grooves, and the lower part that does not enter the groove is opened to form a base part. In other words, it is possible to form a projecting portion with a height along the body of the body at any position in the longitudinal direction. In order to make it easier for the user to use this foldable type, it can be sold in a state in which a portion that becomes a protruding portion is folded in advance. In addition, at the time of manufacture, the projecting portion formed when folded in two can be curved in the longitudinal direction and processed so as to more closely follow the body.

  As a result of sending a daily life including walking with the completely independent sanitary product of the present invention, the inventor of the present invention made a prototype by experiment, and as a result, it fell off even though it was not stuck anywhere. I never said that. However, for those who are worried that they will slip off, extend the front and back in a band and attach both ends of the underwear to the lower umbilicus and the lower part of the waist. Can be eliminated. If the bottom is attached, the mobility with respect to napkins and underwear will be impaired, it will be difficult to remove because it is contaminated with menstrual blood, etc., and the structure will become complicated and expensive, making it difficult to handle. As I did, I decided to attach the end in the vertical direction to my underwear. The reason for attaching the vagina to the place away from the crotch groove of the buttock is that the vagina to the buttock are completely independent from the underwear and the napkin, and want to keep in close contact with the groove.

  When these products of the present invention are used completely independently, and both front and rear ends or one of them is attached to underwear, a conventional napkin is used in combination, but it becomes a foundation. Since the product of the present invention efficiently absorbs menstrual blood by having such a portion, menstrual blood is less likely to reach the conventional napkin, and it is only necessary to replace the compact product of the present invention. Because the need is reduced, the amount of garbage is greatly reduced. The napkin to be used in combination is economical because the product of the present invention plays a role, so that it is not necessary to use a large or walled napkin. In addition, when used in combination with a reusable cloth napkin sold at an ecology shop, the waste can be further reduced. In the case of the present inventor, we have experimentally used the product of the present invention that was originally prototyped. However, after changing the napkin once in the morning, the prototype of the present invention is replaced several times during the day and then goes to sleep. There are many patterns of changing the napkin before. Even during bedtime, menstrual blood does not go backwards, and it has a great effect, so the napkin is often not dirty in the morning. On days with low menstrual flow, the napkin is often not dirty at all. Even in that case, the napkin is changed at night, but the amount of garbage on the napkin is drastically reduced. Even if the product of the present invention is replaced the same number of times as a conventional napkin, the product of the present invention has a smaller capacity than that of the napkin, so that the amount of dust can be reduced as viewed relatively. Moreover, with a conventional napkin, even a little dirt causes discomfort, but if the present invention is replaced, even if the napkin is slightly dirty, the napkin and the body are not in close contact with each other, so there is discomfort due to menstrual blood. almost none. On days when menstrual blood is high, the product of the present invention may not be replaced for 4 to 5 hours. In that case, menstrual blood reaches the napkin, but the menstrual blood must pass through the product of the present invention before the napkin. Therefore, the spread of menstrual blood on the napkin can be suppressed and leakage can be prevented. If there is no base part and it is just an elongated shape, even if the cross section is a circle, triangle, square, or other polygon, it suppresses the spread of menstrual blood on the napkin used together Even if it is possible, especially when a lot of menstrual blood comes out, in the case of the present invention, menstrual blood that should be received by the base flows to the napkin if there is no base part, so the napkin is less dirty It seems difficult to avoid. Then, depending on the person, a person who feels uncomfortable with a little dirt changes the napkin every time he goes to the toilet, so that the napkin with less dirt is discarded. In terms of waste reduction, it can be said that the effect of the foundation is great.

  The product of the present invention that is used completely independently does not need to use an adhesive or the like, and if a material that dissolves in water is used, it can be directly poured into a toilet. If it is better for the environment not to flow, do not flow. Even from a cost standpoint, the structure is simple, so it is considered that it is cheap and easy to manufacture and sell. The shape is stable, looks simple, is inexpensive, easy to use, and generally accepted.

  Although it may cause anxiety that it will rub when it is sandwiched in the crotch groove, it has been found that this point cannot be rubbed by the following experiment. The inventor used the prototype of the present invention using toilet paper as the material many times for the experiment, but never rubbed the material to tatter. On the other hand, when toilet paper is laid and used without affixing to underwear like a napkin, it is greatly displaced and rubbed in the front and back and rubbed, that is, if it is caught in a groove, Because it works, there is rather little friction. Therefore, the material is hardly displaced and the material is hardly rubbed.

  The width of the product of the present invention with the bottom attached to the underwear is easily accepted by people who want to change the napkin every time they go to the toilet, and it does not reduce the amount of garbage, but it is efficient by making it a mountain shape It can absorb menstrual blood and is easy to handle with less discomfort. When the conventional napkin is deformed due to the pressure of the thigh, no matter how much it is devised, it spreads and leaks, but the product of the present invention can prevent such problems by making it a mountain shape. The effect of forming both sides of the Yamagata lower than the rise of the protrusion even when pressure is applied from the side is that the protrusion of the both sides of the Yamagata does not interfere with the protrusion, making it difficult for the protrusion to come out of the groove Therefore, menstrual blood is absorbed in the protruding portion. Moreover, by providing a certain amount of thickness rather than a thin wall, menstrual blood can be absorbed on both sides, preventing leakage to underwear and deformation. The protruding portion is sandwiched in the groove and given a height, so that it is easy to catch menstrual blood in order to keep the mountain shape where a conventional napkin is deformed by a pressure from the side to maintain a mountain shape.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view of a first embodiment of the present invention. The sanitary product of the present invention, which is composed of a portion that becomes a base of 1 and a protruding portion of 2 and has an upper surface formed in a convex shape, prevents deformation and is stable by giving the base portion an appropriate width and thickness. The protrusion 2 is prevented from coming off the groove from the female genital to the buttocks. If it comes off, there is a foundation, so it will not roll and it will be easy to return to the groove. If the foundation is thin, it will be deformed and the effect of the foundation will be lost. If it is only a protruding part, even if the cross section of the protruding part is not a circle, it is a triangle, square or other polygon, but if it is used independently without being attached to underwear or a napkin, There is a high possibility of rolling and coming off due to complicated movement. If there is a foundation, the protruding portion 2 of the present invention may have any shape. It is more important that the protruding portion 2 has a certain moderate height rather than a shape. The connection between the base part 1 and the projecting part 2 should be rounded to follow the body or have a gentle shape. That is, it is preferable that the outer shape is formed along the both sides of the crotch groove. In addition, the projecting portion and the base portion may be integrated, but another may be connected by the material of the top surface and the bottom surface.

  In order to increase the degree of adhesion to the body in a form that more conforms to the body, it is preferable to make the protrusion on the heel portion gently higher as shown in FIG. In the case of the present invention that is not curved in the longitudinal direction as shown in FIG. 1, the degree of adhesion is further increased by doing so. Also, it should be lowered toward the front and flattened at the front end. The main reason for flattening the front edge is not to say that it is sluggish, but it is because the body shape is more flattened depending on the front position. When pinching, be sure to bring the front and rear ends to your favorite position. It is best to bring the protrusions and body dents roughly together, but even if they are not perfect, there are sufficient effects if there are protrusions and base parts. If the height is increased as the protruding portion is moved backward, even if only the protruding portion is at the rear, the necessary effect can be exhibited, so it does not matter.

  FIG. 2 is an external perspective view of the second embodiment of the present invention, wherein the sanitary product of the present invention is curved back and forth along the crotch groove. If it is a straight line, the force to return to the straight line works. Since it is pressed by underwear, it does not actually become a straight line, but by attaching a curve, the degree of close contact with the body increases. The degree of the curve may be gentle, but a curve that follows the groove is good.

  Even if the product of the present invention is not curved, it is preferable to use a material that can be curved by holding it along the groove and keep the state. For example, according to an experiment by the present inventors, it has been found that when toilet paper is used as a material, it can be curved along the groove at the time of wearing, and the state is well maintained. Rarely, it tried to become a straight line on the buttock side depending on the situation, but it was likely to come off from the groove, but it did not become a straight line in underwear, and there was no particular inconvenience. If the material is difficult to keep the curve, it can be processed into a curve, or the protrusion can be raised on the heel side.

  The third embodiment is a folding type as shown in FIG. The user opens the remaining lower part by sandwiching the protruding part 2 formed by folding the part that is sold in a flat state, almost flat state or half-folded into two when used. Thus, the base portion 1 is formed and the upper surface is convex, and the first and second embodiments of the present invention product are used. At the time of manufacturing, if the portion that becomes the projecting portion 2 is processed into a curve as shown in FIG. 8, the shape becomes more conforming to the body. When packaging and selling, it is better to wrap in flat or tri-fold or otherwise compact, even if it is not folded in half. The point is that, when used, it should be in a state of being folded in half so as to be in the form of the first or second embodiment.

  FIG. 4 shows a fourth embodiment of the present invention, in which the longitudinal direction of the first to third embodiments is extended in the form of a belt, and both ends thereof or one of them is placed under the navel of underwear. It can be attached to the bottom of the buttocks. If the sanitary product of the present invention is mounted so that the protruding portion 2 is sandwiched between the grooves, the band may be either slack or stretched with respect to the underwear. The band in FIG. 4 is the product of the present invention with the upper surface extended, but another material may be used. When either one is attached, only one of them may be extended.

  FIG. 5 is a cross-sectional view of a fifth embodiment of the present invention, in which the width of the base portion 1 of the product of the present invention of the first or second embodiment is widened, and both lateral sides are raised, The cross section is a mountain shape, and the back surface is attached to the underwear as a whole like a conventional napkin. The raised part on both sides is not a thin wall like a conventional napkin, but a gentle rise with an enemy's thickness, and when pressure is applied from the side, To be higher. By doing so, the conventional sanitary products are deformed into a U shape by the pressure from the side, so both sides were often soiled. However, with the sanitary products of the present invention, the mountain shape is maintained and the protruding portion is Because it is close to the crotch, it prevents menstrual blood from spreading. In addition, by providing thickness on both sides, the menstrual blood can be absorbed and the underwear can be prevented from being stained. Even in this case, it is better if the front is flattened so that it conforms to the body shape.

  The present invention preferably has a length of 15 cm or more in the longitudinal direction. In experiments by the inventors, 17 cm and 18 cm were most often used. In the first to fourth embodiments, the base portion 1 has a width of, for example, 2 cm or more and a thickness of 0.1 cm or more. The width and thickness may be adjusted depending on the amount of menstrual blood and the position. However, if the width of the base part is too wide around the vagina, it will be deformed by the pressure of the thighs, so it seems that 2 to 3.5 cm is easy to use. For example, the height of the protrusion is about 3 cm at the highest point on the hip. If it is flat at the front, it may be about 0.5 cm otherwise. If you want to keep the height constant, it is better to make it about 1 cm and leave the foundation behind. The height should not be too shallow and not too shallow with respect to the groove. The width is, for example, about 0.5 cm to 1 cm. Both width and height may be changed depending on the position. The overall height should be approximately from the napkin to be used together. In the mountain-shaped product of the fifth embodiment, the overall width may be the same as or narrower than that of a conventional napkin. The reason why it may be narrow is that even if it is too wide, it is pushed and narrowed by the pressure of the thigh. The height of the protruding part is about to hit the depression. The width of the protrusion is about 1.5 cm. The width of the protruding portion is wider than that of the first to fourth embodiments because the bottom surface is attached to the undergarment in this case, so it tends to be separated from the depression. This is so that menstrual blood can be received. Even in this case, the height and width may be changed depending on the position.

  The size, length, thickness, and height of the projecting part and foundation part corresponding to each day, such as daily use with a large amount of menstrual blood, daily use for small items, cages, large people, small people, etc. If the changed product of the present invention is properly used, waste as waste can be reduced. Moreover, what is attached and what is not attached may be properly used depending on the situation. The product of the present invention whose size is changed may be used without being used together with the napkin even in the case of the first to fourth embodiments depending on the situation.

  In the first to third embodiments, when the height is not changed depending on the position, it is better that the buttock side has no foundation. If the protrusion is low relative to the depth of the groove, if there is a base, it will not be able to enter the groove any more and it will prevent close contact with the recess, so the buttock side has no base part and only the front It stabilizes on the foundation of. If there is a height on the protrusion on the buttock side, either may be used.

  The material of the present invention may be, for example, toilet paper or a conventional napkin or tampon. If it is better for the environment not to flow in water, it may be non-flowable, but if it can be flowed, in the first to third embodiments, since it is not attached anywhere and is completely independent, If you open it wide, it will be easy because it will automatically drop without using your hands.

  Regarding the folding type of the present invention, as an example of the shape, as shown in FIG. 6, as seen in FIG. Keep it wide. For example, it is 6 cm or more. In the case of a foldable present invention product that has been folded in advance, it may be processed so that the protruding part does not return flat, the point is that it is compact at the point of sale, It is only necessary to form a three-dimensional part that will become the foundation during use. Even in a flat state, the projecting portion may be processed so that it can be easily folded in the center at the time of use. Moreover, even if it says bi-folding, what was made into the shape like bi-folding by overlapping two things may be sufficient.

  In the first to third embodiments, as shown in FIG. 7, the capacity may be reduced and the inside may be hollow to reduce dust as much as possible.
