  • Patent number: 6443316
    Abstract: A dripping rack structure includes a rack body formed with multiple fitting holes, dripping bars, sealing caps, an upper fixing seat, a lower fixing seat, a draining sink, a draining connector and fastening members. The rack body is made by integral plastic injection molding so that it has light weight and high strength. The dripping bar is engaged in the fitting hole by tenons and mortises. A water seal is disposed in the fitting hole to avoid leakage. The mounting positions of the dripping bars can be changed according to the size of the wares. The bottom of the rack body is provided with a draining sink having an internal slope face, whereby the water flowing into the sink can be quickly drained out of the rack body through the draining connector. The rack body is mainly made of PP material so that it can be safely used and will not secondarily contaminate the washed glass wares.
