- a cord 13 (described later) connected to the absorbent main body 10 is passed through the communication hole 28.
- the pressing rear end portion 27 When the pressing rear end portion 27 is pressed toward the outer cylinder distal end portion 23 side, the pressing distal end portion 26 slides inside the outer cylinder 21 so that the absorbent main body 10 faces the outside of the outer cylinder 21. Press.
- the opening portion 25 is expanded by the absorbent main body 10. Thereby, the absorptive main body 10 is discharged from the opening portion 25 to the outside of the outer cylinder 21.
- FIG. 2 is a perspective view of the absorbent main body 10.
- FIG. 3 is a developed plan view of the absorbent main body 10.
- the absorptive main body 10 has a sheet shape.
- the absorptive main body 10 is accommodated in the outer cylinder 21 in a compressed state.
- the absorbent main body 10 has a connecting portion 14 at a predetermined position.

- the covering material 11 includes hydrophobic fibers 101 having a low affinity for water and hydrophilic fibers 102 having a high affinity for water.
- the abundance ratio of the hydrophobic fibers 101 on the outer surface 11B is larger than the abundance ratio of the hydrophilic fibers 102.
- the blending ratio of the hydrophilic fibers 102 on the outer side surface 11B is preferably 10 to 50% with respect to the total amount of the covering material 11.
- the blending ratio of the hydrophilic fiber 102 in the outer surface 11B is 10% or less, the affinity between the outer surface 11B and water is lowered. Therefore, menstrual blood adhering to the absorbent main body 10 travels along the outer surface 11B of the absorbent main body 10 before shifting from the outer side surface 11B to the inner side surface 11A, and easily leaks from the vaginal opening.
- the affinity between the outer surface 11B and water is increased.
- the outer surface 11B sucks a small amount of menstrual blood on the vagina wall, so that the outer surface 11B sticks to the vagina wall, causing pain and discomfort to the user during extraction.

Thereby, a bodily fluid can transfer rapidly toward the inner side surface 11A from the outer side surface 11B. The spunlace nonwoven fabric is also advantageous in that there is no residue of raw cotton oil.
- the hydrophobic fiber 101 is preferably a synthetic fiber such as polyester, polyolefin, polyamide, polyacryl, or a mixture thereof. Moreover, since the absorptive main body 10 becomes high temperature and a high pressure when compressed and stored in the outer cylinder 21, it is preferable that the melting point is 130 ° C. or higher and the breaking strength of the nonwoven fabric (JIS L1096) is 12 mN / 25 mm.
- hydrophilic fiber 102 examples include rayon (including conventional normal rayon and modified rayon), cotton, ground wood pulp, wool, silk, chemically modified, modified, or crosslinked cellulose fiber, synthetic fiber, tissue, peat moss.
- the fiber generally used as an isoabsorbent can be used. Further, these fibers may be mixed and used.
- the hydrophilic fiber 102 is preferably the same material as the absorber 12 described later. When the hydrophilic fiber 102 and the absorbent body 12 are made of the same material, the familiarity between the hydrophilic fiber 102 and the absorbent body 12 is good, and body fluid such as menstrual blood can be easily guided to the absorbent body 12.
- the fiber diameter of the hydrophobic fiber 101 and the hydrophilic fiber 102 is preferably 1.7 to 3.3 denier.
- the fiber diameter is 3.3 denier or more, the rigidity of one fiber increases, and the user feels uncomfortable.

- the basis weight of the hydrophilic fiber 102 forming the inner surface 11A is preferably 8 to 40 g / m 2 . In the case of 8 g / m 2 or less, it is difficult to produce a web in a stable amount when the raw cotton is opened due to too few fibers.
- the menstrual blood adhering to the absorbent main body 10 is moved to the outer side surface 11B of the absorbent main body 10 before moving from the outer side surface 11B to the inner side surface 11A. It is transmitted and becomes easy to leak from the ostium of the vagina.
- the basis weight of the hydrophilic fiber 102 exceeds 40 g / m 2 , the rigidity of the covering material 11 becomes too high, so that when the absorbent main body 10 is inserted into the vagina, the shape of the absorbent main body 10 is changed. The operation to recover from the compressed state to the use state is hindered.
- Absorbent body 12 absorbs rayon (including conventional normal rayon and modified rayon), cotton, ground wood pulp, wool, silk, chemically modified, modified, or crosslinked cellulose fiber, synthetic fiber, tissue, peat moss, etc.
- the fiber generally used as a material can be used. Further, these fibers may be mixed and used.
- the absorbent body 12 may be mixed with an absorbent polymer, an absorbent gel material, or the like.
- the basis weight of the absorbent body 12 is preferably 100 to 1200 g / m 2 .
- the cord 13 is composed of a single yarn made of rayon, cotton, polyethylene, polypropylene or the like or a composite yarn obtained by twisting these.
- the cord 13 is preferably water-repellent with paraffin or the like in order to prevent contamination with menstrual blood or body fluid.
- the absorbent main body 10 is stored in the outer cylinder 21 in a compressed state.
- the absorbent main body 10 is compression-molded into a substantially cylindrical shape with a mold having a plurality of convex portions in the longitudinal direction.
- the absorptive main body 10 is compression-molded to a specified dimension by being pressed from a conveyance direction (MD direction) and a cross direction (CD direction), respectively.
- the length of the absorbent main body 10 after compression is preferably 30 to 60 mm. If the length of the absorbent main body 10 after being compressed is 30 mm or less, the area of the absorbent main body 10 that contacts the vagina wall is too small, and menstrual blood cannot be sufficiently absorbed. When the length of the absorbent main body 10 after being compressed exceeds 60 mm, the absorbent main body 10 expands to the vicinity of the vaginal opening when it absorbs menstrual blood and the like, causing a sense of discomfort to the user. .
- the length of the absorbent main body 10 after compression molding is 30 mm to 60 mm
- the length of the cord 13 is preferably in the range of 150 mm to 250 mm.

- the basis weight of the hydrophilic fiber 102 is larger than the basis weight of the hydrophobic fiber 101. That is, the fiber layer made of the hydrophilic fiber 102 is thicker than the fiber layer made of the hydrophobic fiber 101. Since the amount of the hydrophilic fiber 102 is large, the covering material 11 itself can absorb the body fluid, and the familiarity with the absorbent body 12 is good.
- the covering material 11 is a spunlace nonwoven fabric in which hydrophobic fibers 101 and hydrophilic fibers 102 are formed by a hydroentanglement method. That is, since the hydrophobic fiber 101 that mainly forms the outer surface 11B and the hydrophilic fiber 102 that forms the inner surface 11A are entangled in the thickness direction of the covering material 11, the outer surface 11B and the inner surface 11A are intertwined. A heading channel is formed. Therefore, it becomes easy for body fluid to permeate from the outer surface 11B to the inner surface 11A.
