Description

200303186 A7 B7 V. Description of the invention (1) [Technical field to which the invention belongs] (Please read the precautions on the back before filling out this page) The present invention is a sanitary product for women, and is about the absorbency of sanitary napkins, etc. Cotton pads for item installation. [Prior art] In the past, as sanitary articles for absorption of body fluids, absorbent articles that absorb the body like a sanitary napkin have been widely used. Here, especially for high-demand sanitary napkins, many efforts have been made to prevent menstrual bleeding. However, the so-called sanitary napkin is originally installed in underwear. If it is not installed closely to the inside of the wearer's thigh, a gap is easily created between the wearer's body and the sanitary napkin, and menstrual blood is easy to pass through the gap. leakage. At this point, in Japanese Patent Application Laid-Open No. 10-1 2 7 6 9 2, it was revealed that a rod-shaped body having a water-absorbent material was formed, and the cross-section was made into a triangle-shaped auxiliary absorbent for physiological use. The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed the physiological auxiliary absorber. When the wearer is wearing a sanitary napkin, it is buried between the inside of the wearer's thigh and the sanitary napkin. Compared with the case of using a sanitary napkin alone, it can be said that the leakage prevention effect of menstrual blood is improved. However, the auxiliary absorbent body for physiology is only made of slender rod-shaped materials with high absorptivity, so it has high rigidity. Depending on the movement of the wearer, it may not be able to maintain the original state. There may be a gap between the inner thigh (especially the gluteal groove) and the sanitary napkin. At this time, because menstrual blood is easy to leak from the gap, the paper size is not applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) -5- 200303186 A7 B7 V. Description of the invention (2) Auxiliary physiological hygiene Cotton gives full play to the so-called leak-proof function of menstrual blood. (Please read the precautions on the back before filling out this page.) So, the conventional auxiliary products like the above-mentioned auxiliary auxiliary absorbers for physiology can only assist the menstrual absorption of physiological sanitary napkins in a stable state. It is not yet possible to sufficiently ensure tight adhesion to the inside of the thigh of the wearer in response to the wearer's activities and the like. The present invention has been made in view of the above-mentioned subjects, and an object thereof is to provide a physiological hygiene that can maintain the tight adhesion with the inner side of the thigh of the wearer while wearing, reduce the leakage of body fluids, and have a comfortable wearing feeling. Cotton pads for the installation of absorbent articles such as cotton. [Summary of the Invention] In order to solve the above-mentioned problems, in the present invention, an auxiliary article intended to be placed on an absorbent article is formed into a shape that can be buried in the gap between the inside of the wearer's thigh and the absorbent article, and can be fitted after wearing. The movement of the wearer is softly deformed. Specifically, the wearer bends the absorbent body so that the absorbent body is directly installed on the absorbent article in a state where there is space in the absorbent body. More specifically, the present invention provides those having the following characteristics. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economy The anti-body side surface of the absorbent article is provided with a buckling area protruding toward the wearer's body side when worn, and the buckling area is provided with a maintaining means for maintaining the buckling state of the corresponding buckling area, and is used to continue to the above absorption The adhering portion of the sexual article is provided on the bottom of the anti-body side of the above-mentioned flexion area. This paper size applies to Chinese National Standard (CNS) A4 specification (210X297 mm) -6- 200303186 A7 ___B7 V. Description of the invention (3) (Please read the precautions on the back before filling this page) About the auxiliary cotton pad of the present invention It has a flexion area that is bent with the body side as the top. Therefore, when an absorbent article such as a sanitary napkin is used, the auxiliary cotton pad of the present invention can be provided on the body side of the absorbent article, so that the inside of the wearer's thigh and the absorbent article can be placed between them. It is in a state where no gaps are generated, and it can be maintained during wearing. That is, since the auxiliary cotton pad of the present invention has a buckling area formed by bending the entire absorbent sheet, a space is formed on the inner side (anti-body side) of the buckling area. Moreover, the shape of the auxiliary cotton pad itself is appropriately deformed in this space, which can buffer external pressure such as body pressure, and respond to changes in wear during wearing. The auxiliary cotton pad and the inner side of the wearer's thigh can be maintained. The recessed portion is closely attached to prevent a gap between the auxiliary cotton pad or absorbent article and the inside of the wearer's thigh. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs as described above, the flexing field of the auxiliary cotton pad of the present invention is formed by only bending the entire sheet, so it has flexibility and can be flexibly coped with. On the inside of the thighs of each wearer, it also provides a non-stiff feel. In this regard, as in the case of the above-mentioned auxiliary auxiliary absorbent body for physiology, rigidity is high only when the absorbent material is formed into a rod shape or a triangular shape, which not only gives the wearer a foreign body sensation when mounted, but also is difficult to deform due to its rigidity. Therefore, the auxiliary absorbent body itself is not easy to buffer the external pressure such as body pressure, and the external pressure is directly transmitted to the fixed adhesive surface of the absorbent article used. As a result, the auxiliary absorbent body can be used from a sanitary napkin in the packing. The risk of falling off. At this time, it is not allowed to bury this paper. Applicable to China National Standard (CNS) A4 specification (210X297 mm) 200303186 A7 B7 Printed by the Consumers ’Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (4) The gap in the gluteal groove causes menstrual blood to flow out The danger becomes higher. In this regard, the auxiliary cotton pad of the present invention can flex flexibly because its flexion field can correspond to the movement of the wearer, so that it can prevent the gap from being created between the wearer's body and effectively prevent the outflow of body fluids, while maintaining and The place where the absorbent article is held and can assist the absorption of body fluids. When the absorbent article is attached to the body, the auxiliary cotton pad of the present invention is a portion located behind the absorbent article, that is, a portion near the buttocks when attached. By doing so, it is possible to bury the gluteal groove that is most likely to form a gap between the body and the absorbent article, preventing the body fluid from flowing from the space to the back and causing the body fluid to adhere to the skin in a wide range, which can effectively prevent staining. Skin or panties. In this way, the auxiliary cotton pad of the present invention improves the performance of a commercially available existing absorbent article and makes the wearer no longer feel uneasy about leakage of body fluids, and brings about an expansion of the wearer's field of activity or Hygiene products with active effect. (2) The above-mentioned maintaining means is a restraint sheet provided in such a way as to cross from the bottom edge of one of the buckling areas to the bottom edge of the other. State of flexion. According to the auxiliary cotton pad of the present invention, a restraint sheet is provided on the side opposite to the body so as to cross from the bottom edge portion of one side of the flexion area to the bottom edge portion of the other side. Therefore, during installation, it is possible to prevent the expansion of the buckling area due to external pressure or the wearer's movement, and to prevent the space formed inside the buckling area from being squashed. Especially, it is very useful for long time use. (Please read the precautions on the back before filling this page) The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X Μ? Mm) -8-200303186 A7 B7 V. Description of the invention (5) (Please read first Note on the back page, please fill in this page again.) Also, since the buckling area can be prevented from expanding outward before use, the wearer does not need to pay special attention, and the shape of the buckling area can be maintained until the auxiliary cotton pad of the present invention is installed. (3) The restraint sheet is a part provided in the buckling area. According to the auxiliary cotton pad of the present invention, in the buckling area ', the restraint sheet is arranged in such a manner that there is a restrained area in which the expansion is restricted and a non-constrained area is not restrained. Therefore, by placing the restraint area in a body part having a recessed portion, it is possible to 'make the buckling area continue to the deepest part of the recession in a non-resistive manner' in the restraint area in the flexion area of the unconstrained area. It can be spread out to closely follow the vulva. Thus, according to the auxiliary cotton pad of the present invention, since the buckled portion can be deformed along the shape of the inside of the wearer's thigh, the leakage of body fluid can be effectively prevented. (4) The bonding portion is a surface provided on the side opposite to the body of the restraint sheet. The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs prints the auxiliary cotton pad according to the present invention for fixing to the adhering part of an absorbent article for use, and is provided on the opposite side of the restraint sheet that restrains the expansion of the flexion field. . At this time, the arrangement of the bonding portion is preferably set at least at the joining position where the restraint sheet and the auxiliary cotton pad body are joined, that is, near the two bottom edges corresponding to the buckling area. Since the load related to the body pressure of the auxiliary cotton pad is concentrated on the bottom edge of the buckling area, the Chinese national standard (CNS) A4 specification (210X297 mm) is applied by setting this paper size. -9-200303186 A7 B7 V. Description of the invention (6) (Please read the precautions on the back before filling this page), it can strengthen the state that the auxiliary cotton pad is fixed to the absorbent article, thereby making the auxiliary cotton pad difficult to change due to movement during wearing. It is peeled from the fixed and adhered absorbent article. (5) The two bottom edges of the above-mentioned buckling area are connected to a flat area extending from the ends of the bottom edges toward the outside and coming into contact with the body when being fitted. The auxiliary cotton pad of the present invention includes a flat area extending from the left and right bottom edges of the buckling area. With regard to this flat area, since it will be fixed at the position covering the vulva when it is mounted, the body-side surface of the auxiliary cotton pad can be caused to follow the surface of the wearer's vulva. Therefore, the surface of the auxiliary cotton pad can contact the wearer's body in a wide range without giving the wearer a distinct foreign body sensation, which can increase the maximum absorption capacity of the auxiliary cotton pad. In particular, by making the absorber in the flat region thinner than the thickness in the buckling region, the foreign body sensation can be reduced further. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the density of flat areas with absorbers with auxiliary cotton pads is higher than that of buckling areas. Because of the capillary phenomenon, the body fluid absorbed in the buckling areas can be oriented The flat area moves, so you can make the best use of the maximum absorption capacity of the auxiliary cotton pad (see Figure 10). Furthermore, according to the auxiliary cotton pad of the present invention, since the adhesive portion of the absorbent article is fixedly disposed on the surface opposite to the body side of the flat area, the adhesive portion is also easy to maintain a flat shape. Therefore, after the auxiliary cotton pad is attached to the body, the underpants fixed with the absorbent article are pulled up, and the underpants can be prevented from being pulled up when the auxiliary cotton pad is attached to the absorbent article. The adhesive parts are stuck to each other when they are pulled, or the absorption is used. The paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm). 10- 200303186 A7 B7 V. Description of the invention (7) The surface material of the sex articles is not related to The auxiliary cotton pad of the present invention is then adhered. As a result, the risk of the auxiliary cotton pad falling off from the absorbent article while being worn can be reduced. (Please read the precautions on the back before filling out this page) (6) The above auxiliary cotton pads are flexible. The auxiliary cotton pad of the present invention is provided with an elastic member in order to make it elastic. Therefore, even if the auxiliary cotton pad is wetted by the absorbed body fluid (especially menstrual blood), it can prevent the gap of the auxiliary cotton pad from reducing due to the decrease in the bulkiness of the auxiliary cotton pad when it was originally installed. In addition, due to the rebound force of the elastic member, any deformation of the body shape caused by the wearer's action can be adhered to the surface of the body side of the auxiliary cotton pad to prevent gaps from occurring. (7) The stiffness of the auxiliary cotton pad is preferably 1.5 m N / 2 5] or less than 11111, more preferably 1.05]> 1/2 5111111 or less.

under. V According to the auxiliary cotton pad of the present invention, the direction toward the front and the back of the wearer when mounted is specified as the X-axis direction, and the direction perpendicular to the Y-axis direction is specified as the stiffness toward the Y-axis direction.値 is preferably 1.5mN / 2 5mm or less, more preferably 1. OmN / Employee Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs, printed below 25mm. By providing the auxiliary pad with such stiffness, the inner pad of the thigh, which changes with the wearer's movement, can deform the auxiliary pad with less resistance. Such stiffness can be obtained by applying heat embossing or slit processing to the absorbent body of the auxiliary cotton pad to impart a rigidity difference in the Y-axis direction. Here, when taking into consideration the texture of the skin, the Chinese paper standard (CNS) A4 (210X297 mm) is applied by dividing the paper size. -11-200303186 A7 B7 V. Description of the invention (8) The slitting process caused by the fiber interlacing with poor rigidity is more ideal than the embossing process with the difference in rigidity caused by the density difference. (Please read the precautions on the back before filling in this page.) As the slit processing, you can, for example, extend in a dotted line toward the X-axis direction, and arrange in the shape of a thousand birds toward the Y-axis direction, and cut by a length of 10 mm. Cutting seam processing by a sewing knife. In addition, the above stiffness 値 is a sample obtained by measuring a short length of 38 mm in the transverse direction near the center of the auxiliary cotton pad and a length of 2 5 mm in the longitudinal direction by a Gurley tester (refer to Section No. 1 8). (8) The above-mentioned auxiliary cotton pad is substantially formed in a longitudinal shape and has a longitudinal direction and a shorter lateral direction. According to the auxiliary cotton pad of the present invention, the auxiliary cotton pad is substantially formed in a longitudinal shape. Therefore, the top of the flexion field can be fitted along the inner side of the wearer's thigh, specifically along the central part of the wearer's thigh that extends from the vaginal fissures toward the perineum and is connected to the gluteal groove. This can effectively prevent the leakage of body fluids, especially the leakage of body fluids toward the rear caused by the cracks flowing from the hips along the back. (9) In the buckling area, the height of the top is gradually increased from one end to the other in the longitudinal direction. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs According to the auxiliary cotton pad of the present invention, the top of the flexion field is gradually raised from one end of the auxiliary cotton pad to the other. By arranging the auxiliary cotton pad of the present invention on the absorbent article such that the heightened portion faces toward the rear side of the absorbent article in use, the inclined flexion area can more easily conform to the shape of the wearer's buttocks. That is, the auxiliary cotton paper size of the present invention should be used in such a way that the heightened portion is placed near the largest gap of the buttocks. The Chinese National Standard (CNS) A4 specification (210X 297 mm) is applicable. ~ -12-200303186 A7 B7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. Description of the invention (9) pads, so the flexion field is more suitable for the gluteal groove that gradually increases in depth from the perineum to the anus of the part. Therefore, the outflow of body fluids exposed along the back can be prevented more effectively. (10) The auxiliary cotton pad is located on both left and right sides with the longitudinal direction as a central axis and forms a waist portion recessed toward the central axis. According to the auxiliary cotton pad of the present invention, both side edges in the longitudinal direction are provided with non-linear curved portions. Therefore, the curved portion will easily fit on the inside of the wearer's thigh. In other words, there are two types of processes that can be used for the installation of the auxiliary cotton packs used for absorbent articles such as sanitary napkins. One is the process of attaching an auxiliary cotton-padded jacket to an absorbent article for use, and fixing it to underwear and pulling on the underwear, and the other is that it is prone to exposure along the spine, such as the buttocks. The auxiliary cotton pad is clamped in advance, and then the underpants fixed with the absorbent article are pulled up so that the auxiliary cotton pad and the absorbent article are followed, and the loading process is performed. Here, during the latter procedure, the auxiliary cotton pad can be directly clamped into the body intended by the wearer, so the auxiliary cotton pad can be surely installed in a suitable position, thereby effectively preventing body fluids. Exposed. However, in this process, when the underpants fixed with the absorbent article are pulled up, it is necessary to prevent the sandwiched auxiliary cotton pad from falling off the body. In this regard, in the auxiliary cotton pad according to the present invention, the shape of the edge portions on both sides is bent in a manner to follow the bending direction of the buttocks or the inside of the thighs. Therefore, when the auxiliary cotton pad is mounted on the body, the flexion of the auxiliary cotton pad is not clamped only by the force of the buttocks, etc., and the contact area between the body and the auxiliary cotton pad will also increase, which will be easier to maintain.

Description of Invention (1 () state. This can prevent the clamped auxiliary cotton pads from falling off the body when pulling up the underwear with the absorbent article pulled up. 1 1) The above-mentioned auxiliary cotton pad is an auxiliary cotton pad for urinary incontinence. According to the auxiliary cotton pad of the present invention, it is not only used as a physiological pad for auxiliary cotton pads, but also used as a countermeasure for urinary incontinence. Since the crotch opening and the urethral opening for urine discharge are located between the labia, the urine pad can be absorbed when the auxiliary cotton pad related to the present invention is used between the labia. Therefore, according to the present invention, since it can be applied to the labia between It absorbs urine especially near the urethral opening, so it can effectively absorb cotton pads for urinary incontinence, especially mild urinary incontinence. (1 2) The above auxiliary cotton pads are auxiliary cotton pads for secretion absorption. According to relevant The auxiliary cotton pad of the present invention can be used for absorption of secretions. That is, according to the auxiliary function of the present invention, it is sandwiched between labia users, because of secretions (leucorrhea) other than menstrual blood discharged from the mouth. ) Can also be absorbed, so it can also be used for this special purpose (for secretion absorption).
