  • Patent number: 4484661
    Abstract: A drip pan for vehicles is made so that it can be used individually or assembled with other identical pans in an array to catch drippings from automobiles or trucks when they are parked. The pans have relatively low walls because the volume of dripping is not substantial, and when made of suitable plastic the pans can be driven over without damaging them. At least one end and one side of the pan are provided with a curved overhanging lip, the outer end of which will overlap the upper edges of walls of another pan which do not have such a lip, so that an array of pans can be formed to cover a large area if desired. The assembly of pans together is easily done and the drippings that normally fall in the junction area between pans are divided by the lips into one or the other of the pans so that the floor is not soiled.
