International Classification:

E03D 9/02

US Classification:

4231

Abstract:

A device for dispensing liquids from under the rim of a toilet by way of the toilet flush water is disclosed. The device includes a first arcuate bottle containing a first liquid and a second arcuate bottle containing a second liquid. The dispensing device has an arcuate base for holding the bottles. A wicking device supported by the base conveys liquid from the bottles to dispensing positions contacted with flush water. A hook is provided for suspending the base from a toilet rim. The majority of the upper surfaces of the bottles are not visible from above the rim of the toilet bowl when the dispensing device is installed on the rim, and the wicking device does not extend outward beyond an edge of the base. The bottles are at least partially spaced apart to define a flush water flow path between the bottles and through openings in the base.

International Classification:

B62D 25/18

US Classification:

280851, 280848, 280154, 280159

Abstract:

The drilling of new holes into a vehicle fender fold is avoided by providing a mud flap with a rotating clamping member. A clamping arm of the rotating clamping member is rotated from a disengaged position to an engaged position behind the fender fold, and is then drawn forwardly on the threads of an attachment bolt to clamp the fender fold between the rotating clamping member and a stationary clamping member in-molded into the mud flap. A visual indicator may be provided to show whether the rotating clamping member is behind the vehicle fender fold to which the mud flap is to be attached.
