However, the drain caps described in Japanese Utility Model Publication Nos. 51-11557 and 51-11558 can smoothly discharge water when desired, but they are poured through a drain opening of a plate. The garbage can be seen directly, causing discomfort when using the sink. This inconvenience can be alleviated to some extent by using a cover having a structure as described in Japanese Utility Model Application Laid-Open No. 4-84472, but the semi-circular flat portion and slope portion of the cover described in Japanese Utility Model Application Laid-Open No. 4-84472 are disclosed. Since both are integrated with the annular wall of the drain cap, the size of the drain opening cannot be changed.

It is an object of the present invention to provide a drain cap in which dust in a trap basket can not be seen during use and a large drain opening can be formed when desired.

[0006]

According to the present invention, a downwardly inclined pouring guide is formed integrally with an annular wall of a drain cap fitted to an upper peripheral edge of a drain trap body, and formed by the pouring guide. The above-mentioned problem has been solved by covering the inflow opening with a flat plate and movably attaching the flat plate to the annular wall. That is, the present invention provides an annular wall fitted to the upper peripheral edge of the drain trap body, a pouring guide portion continuously provided on the inner peripheral side of the annular wall and inclined downward from the inner periphery of the annular wall, and a pouring guide. A flat plate that covers the free edge of the upper part of the part, and a detachable drain cap that covers an upper opening of a drain trap body provided at the bottom of the washing tub of the sink. And is movably attached to the pouring guide portion with an area larger than the area of the pouring opening formed by the above, so that the pouring guide portion and the movable flat plate cover the upper opening of the drain trap body. It is characterized by.

[0007] More specifically, the pouring guide is formed in a funnel shape which is inclined downward from the inner periphery of the annular wall and has a circular pouring opening at the center, and the movable flat plate is provided with the pouring guide. A drainage cap is formed by forming a disk having a diameter larger than the opening area and smaller than the inner diameter of the annular wall to conceal the input opening, and hinge-connecting one end of the flat plate to the annular wall. .

In still another embodiment, the pouring guide portion is formed in a semicircular shape, and is inclined downward from the inner periphery of the annular wall to form a semicircular input opening on a free edge side thereof. The movable flat plate is formed in a semi-circular shape larger than the semi-circular input opening area formed by the pouring guide portion to conceal the semi-circular input opening and to be hinged or connected to the annular wall at one end. A drain cap is formed by rotatably fitting the outer peripheral edge to the pouring guide portion side.

The drain cap is made of a corrosion-resistant material, for example, synthetic resin or stainless steel, and is used by being detachably fitted to an opening of the drain trap body.

[0010]

[Function] The inclined surface of the pouring guide forming the charging opening allows the trash generated in the washing tub of the sink to flow into the drain trap main body together with the water, and the movable flat plate covering the charging opening is in the horizontal state. In this case, it is possible to prevent chopsticks, spoons and the like from falling into the drain trap main body, and to conceal the opening of the drain trap main body so that the trash that has flowed in cannot be seen. When the movable flat plate is raised or rotated, the opening is exposed, so that a large amount of washing water is discharged smoothly and the drain cap is easily attached and detached.
