Abstract:
1. A portion of an enclosure comprising: a blow-molded plastic panel including a first surface, a second surface and a hollow interior portion that are integrally formed during the blow-molding process as part of a unitary, one-piece structure, the first surface and the second surface being spaced apart by a generally constant distance; a first pattern disposed on the first surface of the panel, at least a portion of the first pattern extending towards the second surface of the panel, the portion of the first pattern extending towards the second surface having a lower surface that is spaced apart from the second surface by a first distance; a second pattern disposed on the second surface of the panel, at least a portion of the second pattern extending towards the first surface of the panel, the portion of the second pattern extending towards the first surface having a lower surface that is spaced apart from the first surface by a second distance; one or more overlapping portions where a portion of the first pattern extending towards the second surface of the panel at least partially overlaps a portion of the second pattern extending towards the first surface of the panel, the overlapping portions being spaced apart by a gap that is less than the distance separating the first surface and the second surface; and one or more depressions disposed at one or more of the overlapping portions, the depressions connecting the lower surface of the first pattern and the lower surface of the second pattern, the depressions being integrally formed during the blow-molding process as part of the unitary, one-piece structure.
