JPS5853354Y2 - Combination structure of water storage cover and cover at drain outlet - Google Patents

Description

[Detailed Description of the Invention] This invention relates to a structure in which a water storage lid is combined with a drain outlet of a sink or the like.

Conventionally, the side lids were configured to perform independent functions, and when used as a drain port, they were attached independently of each other. In order to increase the water quality with the
It became necessary to cover it with rubber or other separately prepared elastic material, which resulted in an increase in manufacturing time and cost.

On the other hand, in general, when a water storage lid is fitted to a drain port, the inner wall of the opening and the fitting surface are in an airless state, and the weight and external pressure of the stored water are applied, making it extremely painful to remove it. Moreover, the problem with the cover was that the radially formed sections lost their restoring function during long-term use.

In view of these circumstances, the present invention covers the frame ring with an elastic material, provides one to several protrusions on the upper surface of the rising part, and connects each section inwardly. By organically combining the cover and the water storage cover which can be pinched by its handle, the problems with the unit can be greatly improved.

Hereinafter, the configuration of the present invention will be described in more detail based on one embodiment. 1 is a water tank of a sink, 2 is a drain port 1' of the water tank 1.
The garbage container 3 is a cover fitted to the opening step 2', and is made of, for example, metal or hard plastic, and has a frame ring 4 having an angular cross-section and an inner flange 4'. Covered with an elastic material such as synthetic rubber, one to several protrusions 6 are provided around the upper surface of the rising portion 5, and incisions 7 are made radially from the center of the membrane body 7 connected inwardly. ' are cut to form a large number of sections 8, 8, . . . .

Reference numeral 9 denotes a water storage lid that is integrally molded of hard plastic or the like and can be fitted into the opening of the garbage storage container, and has recesses 10 having a relatively wide range on both sides, straddling the recess 9' on the top surface.
The handle 10 is connected to the handle 10 formed by the shape .

In addition, in the figure, 4' is a large number of through holes penetrated through the inner flange 4' as necessary, and 11 is a peripheral wall that is integrally provided with an edge 11' on the lower surface of the water storage lid. Its outer surface has a certain taper 11'' so that it can be tightly fitted into the inner surface of the third cover.

Furthermore, 12 is a cap embedded in the opening of the garbage container 2;
Also, 13 indicates a kitchen garbage basket.

The combination structure of the present invention relating to the top structure usually has only the cover 3 fitted to the drain port 1', so that each section 8 can be drained in accordance with the flow of waste such as sewage and garbage. Although the elastic opening/closing function can be obtained in the same way as the previous one, the cover 3 has the elastic material containing the frame ring 4 extending inward to form each section 8. The strength at the base of the section 8 supported by the inner flange 4' is significantly improved, and its restoring function can be maintained even after long-term use.

On the other hand, when storing water in a water tank, the water storage lid 9 is simply fitted so that the lower surface of the water storage lid 9 joins to the protruding surface 6 of the cover rising portion 5, and the water storage lid 9 is opened by the weight of the stored water and external pressure. ,
At the same time as being pressed downward, the rising portion 5 that contacts the lower surface is supported by the enclosed frame ring 4 and does not deform, so the contact surface pressure between both members increases significantly and the flow rate of water is reliably prevented. It is possible.

In addition, when the water storage lid 9 is provided with the peripheral wall 11 as described above, the outer peripheral tapered surface 11'' is brought into close contact with the inner surface of the cover 3 to improve water retention. Since the deformation of the part 5 is further restricted, the water-tightness of the part at the time of fitting is further improved.

Furthermore, even with such a water storage lid that has excellent water retention properties, when draining the water in the tank, it is necessary to insert the fingertips below the second finger into the recessed part 10' of the handle 10, and connect the fingertips with the fingertips of the hand plate. By moving this with a child action, the airless state at the contact surface between the water storage lid 9 and the covering lid 3 can be immediately released, so that removal can be easily performed with an extremely small thrust.

As described above, according to the combined structure of the water storage lid and cover lid according to the present invention, only by forming the convex strips on the outer periphery of the cover lid in advance when molding, the elastic material is added separately to the water storage lid. Since it is possible to reliably close the drain port without covering it, it is extremely easy to manufacture and can significantly reduce the cost.
In addition, the cover has various outstanding practical advantages, such as a superiority in the restoration function of each section that could not be expected from conventional ones.
