Definitions
- the present invention relates to an interlabial pad for absorbing menstrual blood, which is used by being engaged between labia of a woman.
- the present invention relates to a structure of an interlabial pad that can reliably absorb menstrual blood.
- sanitary napkins and tampon have been generally used as feminine hygiene products.
- napkins are used in contact with clothing, and because of their poor adhesion to the vicinity of the vaginal opening, menstrual blood tends to leak from the gap with the body.
- the tampon has a problem that it is easy to cause a foreign body sensation when wearing the tampon due to the attribute of the article, and it is difficult to attach the tampon to the vagina.
- the interlabial pad which is located between the napkin and the tampon, has recently attracted attention.
- This interlabial pad is designed to hold a part of the body between the labia of a woman and abut it against the labia, and is more closely adhered to the body than a napkin. It is characterized by being less likely to occur and having less psychological resistance when worn compared to a tampon inserted into the vagina.
- an interlabial pad 24 as shown in FIG. 2 has been proposed (Japanese Unexamined Patent Publication No. Sho 61-1499145). ).
- the interlabial pad 24 is positioned such that the front region 24 a of the pad is located on the front side of the body, the rear region 24 b of the pad is located on the back side of the body, and then the rear region 24 b of the pad is placed. Is bent along a substantially central line 26 in the longitudinal direction of the pad to form a convex portion, and the ⁇ portion is sandwiched between the labia and fixed by the clamping force of the labia itself. According to such an interlabial pad 24, menstrual blood flowing along the inner wall of the labia in the longitudinal direction of the body or flowing along the skin in the lateral direction of the body can be reliably absorbed.
- the interlabial pad described above was still insufficient in its ability to absorb menstrual blood flowing down from the labia toward the body. This is because menstrual blood flows along the inner wall of the labia in the longitudinal direction of the body, or flows down the skin in the lateral direction of the body and is excreted, due to the frictional resistance of the skin and the effects of pubic hair. While the blood flow is slow and the amount of menstrual blood is small, if it flows down from the labia to the lower part of the body, the menstrual blood that has stayed in the uterus during a momentary change in posture is excreted at once Therefore, the flow rate is high and the amount of menstrual blood is large.
- the above-mentioned interlabial pad is intended to absorb menstrual blood flowing down from the labia toward the body downward only by the convex portion behind the pad arranged parallel to the menstrual blood flowing direction. Therefore, high-speed and large amounts of menstrual blood may flow along the slope of the convex part before being absorbed by the pad, and there is a danger that menstrual blood may flow out of the pad and cause leakage. There is. In such cases, the interlabial pad is smaller than the napkin As a result, the damage caused by menstrual blood leaks will be enormous. Disclosure of the invention
- the present invention has been made in view of the above problems, and an object of the present invention is to reliably absorb high-speed and large amounts of menstrual blood flowing down the body along the inner wall of the labia.
- an object of the present invention is to reliably absorb high-speed and large amounts of menstrual blood flowing down the body along the inner wall of the labia.
- the interlabial pad hereinafter sometimes referred to as “pad”.
- the interlabial pad is provided with a raised area in a part of a flat area having an absorbing ability, and a ratio of the raised area to the flat area is set.
- the present invention provides the following.
- a water-permeable front sheet facing the body side and a water-permeable or impermeable back sheet facing the clothing side are joined in a form that contains an absorbent that absorbs bodily fluids.
- An interlabial pad that is used by being engaged between labia which is substantially flat and has a flat area and a body extending from the flat area along a substantially center line in the longitudinal direction of the flat area.
- a labial region comprising a raised region projecting vertically toward the body side, wherein the flat region and the raised region satisfy the conditions of the following expressions (1) to (3). Pad between.
- the interlabial pad of the present invention has raised areas 34b, 44b and force flat areas 34a, 44a.
- the flat regions 34a, 44a From the body toward the body side.
- the vulva is a substantially flat plate located at the lower end of the raised regions 34b, 44b. Are entirely covered by the flat areas 34a, 44a of the first.
- the raised areas 34b and 44b intervening between the labia absorb the primary excreted body fluids, for example, most of menstrual blood, and must be able to perform high-speed and large amounts of menstrual blood. Even if the raised areas 34b and 44b do not absorb all the water and flow along the slopes of the raised areas 34b and 44b, the flat area 34a that covers the entire vulva , 44a, the menstrual blood is absorbed secondarily. In this way, the raised areas 34b, 44b and the flat areas 34a, 44a are combined so that a high-speed and large amount of flow along the labia inner wall in the downward direction of the body. It is possible to deal with blood.
- the interlabial pad of the present invention is composed of the flat region and the raised region, and the flat region and the raised region must satisfy the following conditions. This is because even if the interlabial pad is composed of a flat area and a raised area, if the shape is not precisely controlled, a gap may occur between the interlabial pad and the body. The interlabial pad may fall off between the labia or the interlabial pad may be sucked. Insufficient collection capacity may result in menstrual blood leaks. In addition, if the shape is not precisely controlled, as in the case of the tampon, foreign matter sensation or discomfort may occur at the time of wearing, and it may be difficult to wear it in the vagina.
- the width of the flat area becomes unnecessarily large, which may cause a feeling of foreign matter or discomfort during mounting.
- the thighs (inner thighs) and the side of the interlabial pad, or the clothing side surface of the interlabial pad, and the undergarment come into contact with each other, increasing the frictional resistance between the two. May fall off between the labia.
- the apparent maximum width ratio W E ZW 2 is When it is 5/6 exceeds, can not and this covering the lateral direction of the vulva in a flat area, not absorbed by the raised region menses Should absorb The area is reduced, and menstrual leakage is more likely to occur.
- the apparent maximum length ratio L i / L 2 is less than 1/3, the portion where the pad's clothing side surface and the underwear come into contact with each other must not be unnecessarily long, but rather be the rear part of the flat area. It also increases the area of contact with the buttocks, making it easier for the pad to fall off between the labia.
- the apparent maximum length ratio L i / L z is more than 1, it is impossible to cover the longitudinal direction of the vulva in a flat area, and a large amount of menstrual blood was excreted at high speed. In such a case, menstrual blood leaks easily occur.
- interlabial of view of (b) pad 4 4 Ri S 0. 5 about Der L / L 2 force, interlabial of Figure 3 is L i ZL 2 approximately 1 (a)
- the ability to absorb menstrual blood in the flat area is higher and can be used favorably when menstrual blood is excreted or the pad cannot be replaced frequently. You.
- “bulky” means the dimension in the direction in which the raised area protrudes
- “width” means the dimension in the short direction of the pad.
- length refers to the length of the pad in the longitudinal direction.
- “apparent” means that each of the dimensions “bulk”, “width”, and “length” is the shortest distance between two points. This is the “distance” between two points that have irregularities in relation to the manufacturing process (in other words, a flat state where the irregularities are developed. The distance between points) may be treated as the actual “width”, etc., so it is carefully defined.
- the "actual width" A of the raised area 81 indicates the path of the convex part of the raised area 81b
- the "actual width” B of the area 81a indicates the convex part of the raised area 81b and the entire path of the flat area 81a
- the apparent width of the raised area 81b is the raised area
- the distance between the two end points of the protruding part of 8 1b is shown, and the apparent width W 2 of the flat area 8 1a is the distance between the two end points of the flat area 8 1a.
- H ⁇ ⁇ ⁇ ⁇ in the above formula (1) is preferably from 5 to 30 mm, more preferably from 10 to 25 mm. If the height H is smaller than this range, the contact area between the inner wall of the labia and the protruding area is reduced, so that it is difficult for the pad to be fixed between the labia, and the pad may fall off between the labia. . On the other hand, if H is larger than this range, a gap is generated between the surface of the flat region and the vulva, due to the excessive bulk of the raised region relative to the depth of the labia. There is a risk of menstrual leakage.
- the value is preferably 2 to 3 Omm, more preferably 5 to 2 Omm. If the area is smaller than this range, the raised area cannot have a sufficient contact area or volume to be interposed between the labia, and the pad tends to fall off between the labia. On the other hand, if it exceeds this range, The increased rigidity of the raised area may make it difficult to pinch it between the labia, or may cause a foreign body sensation or discomfort when worn.
- L in the above formula (3) is preferably from 20 to 15 O mm, more preferably from 30 to: L 10 mm, and further preferably from 50 to 100 mm. This is particularly preferred. If L i is smaller than this range, the raised area cannot have a sufficient contact area and volume because it is interposed between the labia, and the pad tends to fall off from between the labia. . On the other hand, if the width is larger than this range, the length of the protruding region becomes excessive with respect to the length of the inside of the labia, which makes it difficult to pinch it between the labia without difficulty. Or, there is a possibility that a foreign object feeling or discomfort may be caused when wearing.
- the “mountain fold shape” in the present invention does not mean that the entire raised area 54 b is filled with the absorber 53, as shown in FIG. 4 (a). As shown, it means that a hollow area 57 is formed inside the raised area 54b on the clothing side (ie, the skirt side of the raised area).
- the absorber 53b is not limited to the one obtained by actually folding the absorber 53b, but as shown in FIG. 4 (b), the absorber 53b
- the hollow area 57 is formed inside the clothing area of the raised area 53b (that is, the skirt side of the raised area), as in the shape of an inverted U-shape or inverted V-shape. Is widely encompassed.
- the pad deforms following the deformation of the labia even with a low load, It is easy to use and can prevent the appearance of foreign matter and discomfort when worn.
- a water-permeable inner sheet is disposed on the clothing-side surface of the mountain-shaped first absorber, and the inner sheet and the front-side sheet include the first absorber.
- the hollow area in the raised area not only helps to improve the fitting property of the pad, but also allows a finger to be inserted and held when the pad is attached (finger insertion space). ) Can also be used.
- the finger and the absorbent sheet may be absorbed. It is sanitary without contact with body fibers.
- the pad is attached with the belly of the fingertip. The advantage is that it is easy to detect points.
- the flat region 54a is erroneously buried between the labia when the pad is worn, and it becomes easier to sandwich only the raised region 54b of the pad between the labia.
- the raised area 54b can be sandwiched between the labia at a certain position according to the wearer's intention, so that menstrual leakage can be reliably prevented, and furthermore, the pad can be removed. The risk of falling off between the labia is reduced.
- the first absorber (absorber included in the raised area) and the second absorber (absorber included in the flat area) May consist of a single continuous absorber sheet 53c.
- the first absorber and the second absorber do not separate from each other, and there is no gap between them, so that the absorbed menstrual blood flows from the first absorber to the second absorber. Moves promptly to absorber. Therefore, it is possible to cope with high-speed and large amounts of menstrual blood.
- the provision of the second raised area 59 on the clothes side as well as the flat side 54a can significantly increase the capacity of the absorber. You. Therefore, it is possible to cope with a high-speed and large amount of menstrual blood, and even if the pad is used for a long time, the occurrence of menstrual blood leakage due to overflow is reduced. Furthermore, since the second raised area 59 protrudes toward the clothes, it can be picked up with a finger when the pad is attached or detached, which contributes to facilitating the mounting of the pad.
- the third absorbent body included in the second raised area is formed in a mountain-fold shape toward the clothes, thereby forming a hollow area on the body side of the second raised area.
- the rigidity of the absorber 60 decreases, and the absorber 60 easily deforms even under a low load.
- the second raised area 59 is collapsed in the lateral direction of the body by the pressing force from the underwear. Therefore, it is difficult to detect the presence of the pad from outside the clothing (it is not noticeable), There are advantages.
- the rigidity of the second raised area 59 is low, the frictional resistance with the underwear is reduced, and the risk of the pad falling off between the labia is reduced.
- the fibers constituting at least the water-permeable surface-side sheet in the raised region and the first absorber are oriented in the short direction of the interlabial pad.
- the interlabial pad according to any one of 1) to (7).
- the fibers constituting the surface sheet and the first absorbent body By orienting the fibers constituting the surface sheet and the first absorbent body in the short direction of the pad, the absorbed menstrual blood can easily move in the orientation direction of the fiber layer, that is, in the lateral direction of the body. In other words, menstrual blood can be promptly transferred from the first absorber to the second absorber.
- the fibers constituting other members for example, the second absorber, the third absorber, the inner sheet, etc.
- Are oriented in the lateral direction of the pad is also included in the scope of the present invention.
- the “adhesive part” can be formed by applying an adhesive to the front side sheet.
- the pressure-sensitive adhesive that can be used in the present invention include a water-soluble polymer, a crosslinking agent, a plasticizer, and a gel pressure-sensitive adhesive composed of water. I can do it. More specifically, examples of water-soluble polymers include gelatin, sodium polyacrylate, polybutyl alcohol, carboxymethyl cellulose, and the like.
- the plasticizer include water-soluble metal salts such as calcium chloride and magnesium sulfate, and glycerin, wax, paraffin, and the like.
- a pressure-sensitive hot melt adhesive can also be used as an adhesive for forming an adhesive portion.
- Pressure-sensitive hot melt adhesives include styrene-isoprene-styrene block copolymer (SIS), styrene-butadiene-styrene block copolymer (SBS), and styrene-ethylene-butadiene-styrene.
- Synthetic rubber resins such as Lemploc copolymer (SEBS) and styrene-ethylene'propylene-styrene block copolymer (SEPS) are the main components.
- SEBS Lemploc copolymer
- SEPS styrene-ethylene'propylene-styrene block copolymer
- Terpene resin and rosin It can be obtained by melt-mixing a tackifier such as resin and a plasticizer such as wax.
- Silicone resin-based adhesives include silicone resin and fluorine resin as main components, platinum, molybdenum, Examples thereof include a mixture obtained by mixing a plasticizer such as a cross-linking agent such as a metal salt of antimony or the like, an ester-based wax, glycerin, or machine oil.
- a plasticizer such as a cross-linking agent such as a metal salt of antimony or the like, an ester-based wax, glycerin, or machine oil.
- pressure-sensitive adhesives for forming the pressure-sensitive adhesive portion as described above, but it is preferable to use a pressure-sensitive hot-melt pressure-sensitive adhesive in consideration of application stability.
- a pressure-sensitive hot-melt adhesive with high application stability 15 to 25% by mass of SEBS, 15 to 35% by mass of plasticizer, and 40 to 70% by mass of tackifier Melt-mixed.
