Abstract: An additive system for use in a polymeric formulation (plastic) that includes a plurality of visually differentiable elongated streaks contained in a mono-colored base, the visually differentiable elongated streaks are composed of a pigmented material having a random pattern and elongated due to the manufacturing process. The visually differentiable streaks are composed of at least two colors, each having a pigment shade visually differing from one another. The visually differentiable streaks are elongated and randomized during the manufacturing process to resemble the elongated markings present in natural materials such as marble or wood. The visually differentiable markings can be utilized in various color combinations to make lightweight useful articles having a pleasing aesthetic appearance.

Abstract: A deck box includes individual panels and a lid that are able to be assembled to one another without the need for external hardware. A bottom panel is connected to a pair of side panels. The side panels are provided with guides or rails that extend toward the bottom panel. Front and rear panels are provided with guides or rails so that each of the front and rear panel can assemble to and between the side panels, sliding into engagement in a direction toward the bottom panel. A lid has an integrally-molded hinge member that engages with an integrally-molded hinge member of the rear panel.
