1228985 A7 B7 V. Description of the Invention (彳) [Technical Field] The present invention relates to a supplement for an absorbent article that enhances the function of a sheet-shaped absorbent article such as a sanitary napkin or a new function to the sheet-shaped absorbent article. Flakes. [Advanced technology] In the past, sheet-shaped absorbent articles that absorb body fluids such as menstrual blood have been widely used in sanitary napkins. For this sanitary napkin, considerable efforts have been made to prevent leakage of menstrual blood. In addition, various sanitary napkins that absorb menstrual blood are used in various ways in order to improve the feeling of use. In this regard, in Japanese Patent Laid-Open No. 7-18712, a bulge is provided at the back to fix the bulge in the labia, and a gap is provided between the bulge and the nucleus in the front to prevent leakage and prevent leakage. Physiological sanitary napkins that improve the feeling of use (see Figure 7). According to this sanitary napkin, since the raised portion can directly absorb menstrual blood discharged from the cavity opening, leakage of menstrual blood can be reduced and the underwear can be attached. In addition, because the sanitary napkins do not come in contact with the nucleus, even when the sanitary napkins installed in the panties are moved, the sanitary napkins will not rub against the vicinity of the nucleus and prevent inflammation caused by friction. Here, general sanitary napkins are saturated on the surface when a certain amount of menstrual blood is absorbed, so it is difficult to absorb menstrual blood in the deep layers. However, when the sanitary napkins in Japanese Patent Shikai No. 7-187 No. 12 were menstrual blood absorption capacity of the bulge part, the bulge part became difficult to absorb menstrual blood. It will flow out ahead, and this paper size will apply the Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling out this page), printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs- 5-1228985 A7 B7 V. Description of the invention (2) The possibility of leakage from the gap provided between the sanitary napkin and the vaginal nucleus. In addition, because the bulge is formed to be fixed in the labia, the menstrual blood contained in the bulge causes the labia to be wet at any time, and the labia is formed by the mucous membrane, so the resistance to stimulation is reduced. Skin contact is more likely to cause rough skin or inflammation than other areas. However, the menstrual blood absorbed by the sanitary napkin may flow back to the body due to the pressure of the device and cause rewetting. In this case, in the area where the user's skin is in close contact with the sanitary napkin, specifically, the menstrual blood range absorbed by the raised portion may spread the skin, which may cause rough skin or inflammation. In order to prevent rewetting, the first layer of a porous film having an opening larger than that of a sheet provided with a general sanitary napkin is disclosed in Japanese Patent Application Publication No. Hei 1-507577, and the first layer is provided with A sanitary napkin with a double top sheet formed from the second layer of the perforated film without the larger opening. According to this sanitary napkin, the first layer with a higher liquid passing rate passes through the menstrual blood quickly and is transmitted to the second layer due to the large opening. Then, the second layer, which has a lower liquid passage rate than the first layer, blocks the absorbed menstrual blood and reduces the occurrence of rewetting in order to prevent backflow. However, there is a possibility that menstrual blood absorbed by the first layer does not flow to the second layer and returns to the first layer. This situation causes rewetting. The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a range in which menstrual blood absorbed by a sheet-shaped absorbent article is in contact with a user's body and prevent menstrual blood from spreading, thereby reducing rewetting of the skin or absorption of menstrual blood from the absorption. Auxiliary sheet for absorbent articles leaked from sexual articles.

Furthermore, according to the auxiliary sheet for an absorbent article according to the present invention, even if the depth of the through hole is such that the labia is inserted into the through hole, it becomes a sheet-shaped absorbent article located on the side opposite to the body of the auxiliary sheet of the absorbent article, making it difficult to contact. The apex of the labia. However, as in the past, the labia will not come into contact with body fluids after a long time. Here, the average size of the labia of Japanese women is approximately 17 mm, so the depth of the through hole is in the range of 3 to 30 mm, more preferably in the range of 5 to 25 mm, and most preferably in the range of 10 to 20 mm. The through-hole having a depth dimension of this range can ensure a non-contact state between the sheet-shaped absorbent article and the user's labia. However, the auxiliary sheet for an absorbent article of the present invention preferably has a depth of the penetration hole that is deeper than the depth of the labia. It is not necessary that the auxiliary sheet for the absorbent article has the same thickness as the depth of the penetration hole. Therefore, it suffices if the circumference of the through hole is the same thickness as the depth of the through hole, and other portions may be thinner than this thickness. When the auxiliary sheet for an absorbent article of the present invention is used in this way, the direction of flow of body fluid is through a through hole provided in the auxiliary sheet for an absorbent article. As a result, it is possible to suppress the occurrence of rough or irritated skin caused by the user's body in contact with the thin sheet swollen by body fluids. And the body fluid is absorbed from the labia through the through-holes to the flake-shaped absorbent article, so the diffusion is significantly reduced and the leakage to the flake-shaped absorption is significantly reduced.

(Please read the cautions on the reverse side before filling out this page.) According to this type of auxiliary sheet for absorbent articles of the present invention, the through hole is arranged in a portion other than the central portion in the longitudinal direction. This through hole also takes into account the presence of pubic hair near the labia. That is, in many areas where pubic hair is present (pubic hair portion), since the pubic hair prevents the auxiliary sheet for the absorbent article from adhering to the user's body, a gap is easily generated between the auxiliary sheet for the absorbent article and the user's body. Moreover, since the pubic hair is thicker and has a larger surface area than the fibers used for the nonwoven fabric sheet, it is easier to attach body fluids than the fibers used for the nonwoven fabric sheet. In addition, because the pubic hair has fine unevenness (horny layer), once the bodily fluid attached to the pubic hair is caught by the unevenness, it is not easy to detach from the pubic hair. As a result, there is a danger that the body fluid is diffused through the pubic hair, and the body fluid may leak from a gap generated between the auxiliary sheet for an absorbent article and a user's body. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs In this regard, the use of an adhesive to adhere the wearer's body to the auxiliary sheet for absorbent articles can prevent the aforementioned gaps and prevent leakage of body fluids. However, applying an adhesive directly to the pubic hair will pull the pubic hair together when the auxiliary sheet of the absorbent article is removed, which may damage the skin.

(Please read the precautions on the back before filling this page.) The auxiliary sheet 1 of this embodiment is used after being mounted on the side of the body of a sheet-shaped absorbent article such as a sanitary napkin to prevent absorption of body fluids such as sanitary napkins ( Menstrual blood) in direct contact with the skin of the user. According to this function, the size of the auxiliary sheet 1 is smaller than that of a sanitary napkin; in addition, the auxiliary sheet 1 conforms to the crotch of a user to be installed, and its appearance is substantially an oval shape. As shown in Fig. 1, the auxiliary sheet 1 is provided with an oval-shaped through hole 2 in the central portion thereof, and the body side is provided with an adhesive portion 3 near the periphery of the through hole 2. The penetrating hole 2 is formed to have a size that can be smoothly inserted into a labyrinth-shaped labia, so that a user can easily insert a pair of labia into the penetrating hole. In addition, since the through-hole 2 has an oblong shape as described above, menstrual blood spreading along the labia having an elongated shape can be surely introduced from the through-hole 2 to a sanitary napkin (not shown). Therefore, it can reduce the direct contact of menstrual blood to the skin, and can suppress the large-scale residual diffusion of menstrual blood. Because of this, it can reduce rough skin when using sanitary cotton. Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, 8th Industrial Cooperative Cooperative. The appearance size of the auxiliary sheet 1 is preferably in the range of 80 to 200 mm in the lengthwise direction, and more preferably in the range of 130 to 180 mm. The short-side dimension is preferably 40 to 90 mm, and more preferably within a range of 50 to 70 mm. By setting this size, it can be mounted on a sanitary napkin, etc., and it can also be set to an appropriate size. When the auxiliary sheet 1 of the present invention is mounted, the labia 6 is fitted into the through hole 6 as shown in Fig. 2 (A). Therefore, it is not the same as when the sanitary napkin 10 shown in Figure 2 (B) is used alone, and the labia 6 is hardly in contact with the sanitary napkin. The size of this paper applies the Chinese National Standard (CNS) A4 (210X297 mm). ) -29- 1228985 A7 B7 V. Description of the invention (26) (Please read the precautions on the back before filling out this page) Menstrual blood absorbed by cotton 10 to prevent rough skin. However, increasing the thickness of the auxiliary sheet 1 can also make the non-contact between the labia 6 and the sanitary napkin 10 more reliable. [Modification of Through Hole] Next, a modification of the auxiliary sheet 1 in this embodiment will be described. Fig. 3 is a longitudinal sectional view showing a state in which the auxiliary sheet 1 is installed in the embodiment in which a through hole 2 is provided in the center from the side when viewed from the side. Fig. 4 is a view showing the auxiliary sheet 1 with the through hole 2 shifted to the rear. Fig. 5 is a view showing the auxiliary sheet 11 whose through holes 12 are biased to the rear and the front area 11a is laterally expanded. As shown in FIG. 3, the pubic hair portion 7 in which a large number of pubic hairs are stored in the front area of the labia 6 (near the pubic bone) is generally located in the pubic hair portion 7. The pubic hair prevents the auxiliary sheet 1 from coming into close contact with the body and there is a gap. There is also a danger of menstrual blood spreading through the pubic hair that is sandwiched in this space. Printed by the Industrial and Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Therefore, instead of the auxiliary sheet 1 as shown in FIG. 1, the through hole 2 is arranged in the central part, but as shown in FIG. 4 It is close to the rear end portion, and therefore the front area 11a which is in contact with the pubic hair portion is lengthened during installation, and the front area is used to block the diffused menstrual blood, thereby reducing the leakage of menstrual blood. However, with the offset arrangement of the through-holes 2, the placement of the adhesive portion is also offset, so that it is desirable to prevent the adhesive from sticking to the pubic hair. Further, as shown in Fig. 5, the positions of the through-holes 12 and the adhesive portions 13 of the auxiliary sheet 11 are offset to the rear, and the front region 11a can also be formed in a wide shape. With this shape, the area where the auxiliary sheet 11 comes into contact with the pubic hair becomes larger. Even if the menstrual blood leaked from the labia comes into contact with the pubic hair, the paper size is extended to the Chinese National Standard (CNS) A4 (210X297 mm). -30- 1228985 A7 B7 V. Description of the invention (27) When it is dispersed, the front area 1 1 a with a large area can be used to block further diffusion. (Please read the precautions on the back before filling in this page) [Vertical cross-section structure of the auxiliary sheet] Next, the longitudinal cross-section structure when viewed from the front of the auxiliary sheet 1 will be described. Fig. 6 is a longitudinal cross-sectional view showing the auxiliary sheet 1 according to this embodiment, and also for explaining the double-layer structure formed by the soft-touch sheet 4 and the liquid-impermeable sheet 5. FIG. 7 shows another cross-sectional structure of the auxiliary sheet 1 according to the present embodiment. It is also used for the auxiliary sheet 21 formed by a three-layer structure in which the liquid-impermeable sheet 25 is sandwiched between the soft-touch sheets 24A and 24B. Longitudinal section. As shown in FIG. 6, the auxiliary sheet 1 according to this embodiment has a double-layered structure in which a soft-touch sheet 4 is arranged on the skin side and a liquid-impermeable sheet 5 is arranged on the side of a physiological sanitary napkin. An adhesive or Heat seal to join the two. The soft-touch sheet 4 is comfortable to use, and prevents re-wetting of the menstrual blood of the liquid-impermeable sheet 5 with the skin due to the pressure of the pack in advance. Printed by the Consumer Cooperative of the Ministry of Economic Affairs and the Financial Affairs Bureau. In addition, the auxiliary sheet 21 shown in FIG. 7 can also be provided with the liquid-impermeable sheet 25 disposed on the skin-contacting soft sheet 24A and the contact physiological sheet. The tampon-soft sheet 24B on the sanitary napkin side has a three-layer structure with a sandwich shape. With this structure, the soft touch sheet 24A that touches the skin provides a comfortable feeling to the user, and the soft touch sheet 24B that touches the sanitary napkin absorbs wet menstrual blood and prevents the menstrual blood from flowing. [Modified Example of Adhesive Portion] Next, a modified example of the adhesive portion 3 of the auxiliary sheet 1 of the present embodiment and the adhesive portion 3 of this embodiment will be described. The paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -31-1228985 A7 B7 5 2. Description of the invention (28) (Please read the notes on the back before filling this page). Fig. 8 is a schematic perspective view showing an auxiliary sheet 31 provided with an adhesive portion 33 on the elastic sheet 36; Fig. 9 is a schematic perspective view showing an auxiliary sheet 41 in which a plurality of concave long grooves 47 are arranged side by side in a row in the longitudinal direction in a range where the elastic sheet 46 is mounted. The adhesive portion can also be provided directly on the side of the body of the auxiliary sheet. However, in order to prevent the adhesive from adhering to each other, the adhesive portion is held elastic. For example, as shown in Fig. 8, an elastic sheet can be attached to a region covering the through-hole 32 of the auxiliary sheet 31 and two adhesive portions 33 provided around the through-hole 32. In this way, the adhesive portion 33 has elasticity, and the mounting operation of the user becomes easy. However, as in the present embodiment, when the elastic sheet 36 is mounted in the entire area including the auxiliary sheet 31 in the longitudinal direction, the portion that engages the through-hole 32 is cut out with the same size as the through-hole 32. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. As shown in FIG. 9, it is in the range where the elastic sheet 46 is installed, and a plurality of concave long grooves 47 are arranged side by side in the longitudinal direction to become telescopic. In the movement of the user, the auxiliary sheet 41 expands its width in the short-side direction and becomes flat. Therefore, the skin to which the adhesive is adhered is prevented from being pulled tightly with the action of the user. However, the long groove 47 is formed by a corrugation process by mechanical processing. [Body fluid introduction tank] Next, a body fluid introduction tank will be described. Fig. 10 is a longitudinal cross-sectional perspective view of the auxiliary sheet 51 in which a part of the auxiliary sheet 51 extends toward the opposite side of the body to form a cylindrical body fluid introduction groove 58; Fig. 11 is an explanatory diagram for explaining a state in which the opposite side of the body of the body fluid introduction groove 58 is in contact with the sanitary napkin 50; This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -32- 1228985 A7 _ B7 V. Description of the invention (29) (Please read the precautions on the back before filling this page) 12 The picture shows A longitudinal sectional view of the mounting state of the auxiliary sheet 51 viewed from the front. FIG. 13 is a longitudinal cross-sectional perspective view of the auxiliary sheet 61 having a bottom-like body fluid introduction groove 68 attached to the surface on the opposite side of the body. The auxiliary sheet 11 according to this embodiment has a body fluid introduction groove in order to make it more effective in preventing menstrual blood diffusion. For example, as shown in FIG. 10, a part of the auxiliary sheet 51 formed by the two-layer structure of the soft-touch sheet 54 and the liquid-impermeable sheet 55 is bent from the part of the through hole 52 and extended downward. The extended portion forms a body fluid introduction groove 58. With such a structure, the menstrual blood flowing from the through hole 52 and the labia of the body fluid introduction groove 58 connected to the through hole flows into the sanitary napkin (not shown) and flows into the body fluid introduction groove 58. Effectively prevent menstrual blood from spreading to the labia. However, in this embodiment, since the body fluid introduction groove 58 and the auxiliary sheet 51 are integrally formed, the combination of the two is firm; in addition, the manufacturing process of the joint is omitted to simplify the process. Printed on the 8th Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The auxiliary sheet 51 is attached to the user's inseam by the adhesive part 53, and the sanitary napkin 50 is attached to the panties. However, when the underwear is put on, as shown in Fig. 11, the body fluid introduction groove 58 formed as the auxiliary sheet 51 comes into contact with the sanitary napkin 50. However, the body fluid introduction groove 58 can be bonded to the body side of the sanitary napkin 50 with an adhesive. In this way, the body fluid introduction groove 58 can be fixed at an appropriate position on the sanitary napkin 50, so that the body fluid introduction groove 58 can be prevented from being deviated from the position due to the user's action. When the auxiliary sheet 51 of this embodiment is installed, as shown in Fig. 12, the labia 6 is more secure than the case of Fig. 2 (A) described above in that the Chinese national standard (CNS) is applied to the paper size of the sanitary napkin.

"Naturally degradable" means the gas, water, and biomass that a substance decomposes into carbon dioxide or methane in accordance with the laws of nature in the presence of fungi, bacteria, radiation bacteria, and other microorganisms. It also refers to the natural decomposition energy of the substance ( Natural decomposition rate, degree of natural decomposition, etc.) are comparable to materials naturally produced by fallen leaves, or synthetic polymers with natural degradability generally recognized in the same environment. Printed by the Industrial Property Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs "Water dispersibility" means the same as hydrolyzability, and the amount of water (menstrual blood volume) limited during use is not affected. In a large amount of water or water flow, the fibers are between each other. , Easy to disperse into the nature of at least not blocking the toilet pipeline to a small extent. "Water-soluble" means that the amount of water (menstrual blood volume) that is limited during use is not affected, and it is a large amount of water or a property that can be dissolved in the water stream. There are no particular restrictions on materials and configurations that satisfy the above conditions. The following examples are given. As the fiber for the liquid-permeable material, natural fibers and / or chemical fibers can be used. Examples of the natural fiber include facial paper, pulverized pulp, air-flow pulp chemically combined with a water-soluble resin, and cotton yarn. This paper size of chemical fiber applies Chinese National Standard (CNS) A4 specification (210X297) -35- 1228985 A7 B7 V. Description of the invention (32) (Please read the precautions on the back before filling this page) Examples are Regenerated cellulose such as rayon and fibril rayon; examples of synthetic fibers include synthetic fibers subjected to hydrophilic treatment to PE, PP, PET, and vinyl vinyl acetate; examples of synthetic naturally degradable fibers include polymerization Lactic acid, polybutene hyaluronic acid, and the like; examples of water-soluble materials include carboxymethyl cellulose and polyvinyl alcohol. Among the aforementioned materials, natural fibers such as pulp or cotton, rayon, and fibers having natural decomposition such as polymerized lactic acid are preferably used. However, the aforementioned materials can be mixed and formed into wavy or non-woven fabrics separately. Polymerization of so-called naturally degradable fibers such as lactic acid or polybutene succinic acid can be performed by one of the dry method or the wet method formed by the curd method, the spunbond method, the melt-blown method, or the air-flow method, or a combination of the foregoing plural It is also possible to perform wave-like foaming treatment in any of the methods. The method of adhesion includes methods such as thermal adhesion, needle stick adhesion, and chemical adhesion, but is not limited to these methods. It is also possible to use a spinning needle formed into a thin sheet by a water-jet weaving method. Examples of printing methods with water-dispersibility by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs include the method of forming fibers into thin sheets through hydrogen bonding between fibers to form hydrolyzed paper, and the use of water-soluble binders. A method of combining fibers with each other to form a sheet to form a hydrolyzed paper, or a method of interweaving fibers into a sheet to form a hydrolyzed paper. However, in order to have good water-dispersing properties, a fiber length in the range of 2 to 5 1 mm is preferable, and a range of 2 to 10 mm is more preferable. Furthermore, in order to maintain water dispersibility and strength that will not break during use, it is preferable to select a fiber degree (roughness) from 1.1 to 4.4 dtex. When rayon is used as the fiber, the range of the fiber degree is preferably 1.1 to 3.3 dtex. Below this paper size, the Chinese National Standard (CNS) A4 specification (210X297 mm) -36-1228985 A7 B7 V. In the case of the scope of the invention (33), the water dispersibility is good, and fluffing and depilation easily occur when drying. In addition, outside this range, the water dispersibility is significantly reduced. (Please read the precautions on the back before filling this page.) Liquid impervious materials include cellulose importers such as methyl cellulose, carboxyethyl cellulose, and carboxymethyl cellulose; polyvinyl alcohol and acetylene carboxylic acid Water-soluble polymers of soda, polyacrylic acid soda, polyacrylic acid ether, polyvinylpyrrolidone, isobutylene and anhydrous maleic copolymer; or polymer lactic acid, polybutene succinic acid, starch, dextrin, etc. molecule. The aforementioned materials can be formed into thin films by themselves or mixed with the aforementioned materials. Further, the film sheet may be coated with or mixed with a water-repellent material such as silicone resin, or a non-woven fabric formed of the aforementioned material may be laminated. < Joining method > The joining of the sheets is performed by using a joining method such as a water-soluble or water-swellable polyvinyl alcohol, a heat-sealing, or a hydrogen bonding, alone or in an appropriate combination. < Elastic material > Materials produced by the Industrial and Commercial Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs are materials that impart elasticity to auxiliary sheets. Examples of materials that have natural decomposability include natural rubber (cis-1,4-polyisoprene Ene). Since natural rubber is susceptible to attack by oxygen and / or microorganisms or fungi, it is necessary to consider decomposition processes such as chain breakage and molecular weight reduction. Alternatively, it may be a water-soluble elastomer or the like. This paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) -37- 1228985 A7 _ B7____ 5. Description of the invention (34) [Possibility of industrial use] As mentioned above, the auxiliary sheet for absorbent articles of the present invention Because it is sandwiched between a sheet-shaped absorbent article such as a sanitary napkin and the user's body, the contact range between the two is significantly reduced, dampening of the skin caused by wetness is suppressed, and it reduces Re-contact with body fluids causes rough skin. In addition, the labia is embedded in the through holes to prevent the diffusion of body fluids, to prevent the skin from being roughened in a wide range, and to reduce the leakage of body fluids from sheet-shaped absorbent articles.
