Patent attributes
The opposite plastic walls 20a and 20b can be made from a polymeric resin material such as thermoplastic or thermoset resin, and/or can be made from olefins, styrenes, nylons, or mixtures of these polymeric families. In one aspect, the opposite plastic walls can be formed from an olefin, such as polyethylene or polypropylene, or the like. In another aspect, the opposite plastic walls can be formed from a styrene, such as acrylonitrile or butadiene styrene, or the like. In still another aspect, the opposite plastic walls can be formed from a mixture of olefins and styrenes. The polymeric resin material can also be made from recycled olefin, styrene, or nylon products. It will also be appreciated that the material of the walls can include additives, such as glass, fiber, talc, UV resistive or protective materials, etc. In one aspect, plastic granules of different colors can be combined to obtain a wall color that is a composite color to more readily simulate another material.
