Title:
DRAIN PORT BODY
Document Type and Number:
Japanese Patent JP3640653
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a drain port body for repeating smooth drainage and shielding for many years at a low cost with a decrease in the number of parts with no restriction on material in use nor large-scale preparation without impairing mounting easiness to a drain pipe.
SOLUTION: This drain port body 100 is provided with an integrally molded projecting part 22 at a nozzle 21 and a tip 23 of a flexible valve element 20 to superimpose resiliency to hold the shape and internal wall surface contact of the nozzle 21 and tip 23. When a prescribed quantity of drain is accumulated in the nozzle 21, the internal surface wall contact is released to allow the drain to flow outside, and the shape and internal wall surface contact are restored after the completion of drainage.
