Abstract
A molded plastic bowl is formed with a non-slip molded base. Venting is provided during molding of the base to the pre-formed bowl to allow molding gasses to escape the base molding cavity. Venting can be provided through the floor of the bowl, along its inside or outside upper surfaces or through an overhanging ledge formed in the bowl. Suction can also be applied to the molding cavity to remove molding gasses.
