In other words, in the present invention, the tongues 5 having a triangular apex portion 5a are formed by further extending the tip portions on the center side of all the tongue pieces 5 so as to eliminate the round holes in the existing chrysanthemum crack lid. It is said. And since the chrysanthemum crack lid 1 is formed of a material with less plastic deformation, the apex portions 5a, 5a of the tongue piece 5 can be brought into close contact with each other without forming a gap, The drain port space S can be closed with the accommodating portion 17 covering the hole portion 4.

Reference numeral 30 denotes an annular groove formed on the back surface of the innermost ring portion 12 among the plurality of ring portions 12 to 14. A ring-shaped cartridge 32 in which a large number of granular inorganic chemicals having a deodorizing action of about 4 mm (for example, the above-mentioned Kesmon (trademark) manufactured by Toa Gosei Co., Ltd.) 31 is accommodated in the groove 30. It is installed detachably. In this embodiment, the chrysanthemum cracking lid 1 projecting downward from the lower surfaces of the other ring portions 13 and 14 is used as the lower surface of the ring portion 12. The cartridge 32 is made of a synthetic resin and has a circular vertical cross section and is divided into upper and lower parts, and after the plurality of the medicines 32 are accommodated, the upper surface portion 32a and the lower surface portion 32b are joined. Reference numeral 33 in FIG. 4B denotes the joint surface. In addition to joining, a hinge may be provided so that the upper surface portion 32a and the lower surface portion 32b can be freely opened and closed.
And the upper surface part 32a of the cartridge 32 is hold | maintained at the chrysanthemum crack cover 1 in the form which penetrates into the said groove | channel 30. FIG. That is, on the outer periphery of the upper surface portion 32 a of the cartridge 32, a plurality of locking claws 33 having a shape that bites into the inner peripheral surface of the groove 30 are provided with appropriate intervals. Further, the lower surface portion 32b of the cartridge 32 has a plurality of pairs of a pair of appropriately sized vent holes 35, 35 through which a different odor passes on both radial sides of the bottom b at a position higher than the bottom b of the lower surface portion 32b. They are provided in the circumferential direction at appropriate intervals. The vent hole 35 is set to a size that prevents the granular drug 31 of, for example, about 4 mm from coming out. In the state where the cartridge 32 is held by the chrysanthemum lid 1, the lower surface portion 32 b is exposed from the groove 30, and the numerous vent holes 35 face obliquely downward in the drain port space S.
Instead of the vent hole 35, one or more ring-shaped vent holes having a predetermined width formed in a size that prevents the medicine 31 from going out may be provided on the lower surface portion 32b. In the present invention, the means for holding the cartridge 32 to the chrysanthemum lid 1 is not limited to the groove 30 and the locking claw 33.

  Further, in this embodiment, the chrysanthemum crack lid 1 is formed by adding a coloring agent to EPDM as a main material and adding, for example, 1 to 3% by weight of a drug that inhibits the formation of a biofilm. . The chrysanthemum crack lid 1 may be formed by adding a colorant to EPDM and adding 2 to 10% by weight of a powdery agent having an antibacterial effect, or EPDM may contain a colorant. In addition, the chrysanthemum crack lid 1 may be formed by adding an appropriate amount of both a drug that inhibits the formation of a biofilm and a powdery drug having an antibacterial action.

  Thus, a part of the drainage of the sink flows into the storage part 17 to dissolve a part of the medicine 16, and the solution from the storage part 17 passes through the outflow hole 26b to the dust receiving basket 8 directly below. At the same time, for example, the slime of the dust receiving basket 8 can be removed, and the solution from the container 17 passes through the outflow hole 26a to the bottom 5 of the chrysanthemum lid 1 so that the slime of the chrysanthemum lid 1 can be removed. Furthermore, while covering the said hole part 4 with the accommodating part 17, and making the vertex part 5a of the center side of the tongue piece 5 contact | abut, the drain outlet space S just under the chrysanthemum crack cover 1 can be closed, Unpleasant odor accumulated in the mouth space S can be effectively eliminated by adsorption. That is, it is possible to effectively eliminate the odor from the garbage receiving basket 8, the garbage attached to the back side of the chrysanthemum cracking lid 1, or the sewage.

  Moreover, since the deodorizer which removes a bad smell by adsorption is used as the chemical | medical agent 31, there is no gas generation | occurrence | production like another commercially available chlorine-type deodorizing chemical | medical agent, and there is a possibility that the chrysanthemum crack cover 1 made of rubber may deteriorate. Disappear.

  Moreover, in this embodiment, the chrysanthemum crack lid 1 is formed by adding a drug that inhibits the formation of a biofilm or a drug having an antibacterial action, so that it is difficult for slime to occur in the chrysanthemum crack lid 1 for many years. .
