Abstract: A grill cover device includes a flexible cover defining a hollow recess having an open mouth. The recess is adapted to receive an associated grill therein when the flexible cover is in an expanded condition. A flexible resilient frame is connected to the flexible cover. The frame exerts a biasing force on said flexible cover to bias the cover into its expanded condition. The frame and the flexible cover are selectively resiliently deformable as a unit against the biasing force of the frame into a collapsed storage configuration in which the frame and cover are folded upon themselves.
