Abstract: A container for holding granular or powdered material. The container includes a base and a lid. The base defines an interior space and an opening to the interior space. The lid is removably attached to the base and adapted to cover the opening. Latches are attached to the outside surface of the lid on opposing sides of the lid. Inwardly extending lugs on the inside surface of the latch are correspondingly positioned to contact deflectors on the outside surface of the base during attachment of the lid to the base.

Abstract: A stackable display tray including a shell having a plurality of sides defined by an equal number of corners, a substantially closed bottom having bottom corners corresponding with the corners of the shell, and a top having top corners corresponding with the corners of said shell. The top includes at least two first openings each adjacent to an independent top corner, and the bottom includes at least two second openings each adjacent to an independent bottom corner. The display tray also includes a side panel member having at least two angular panels positioned within the shell adjacent at least two of the corners and including a tab projecting from the top of at least two of the angular panels. At least two of the first openings each receive the tab of one of the angular panels positioned within the shell and at least two of the second openings are each adapted to receive a tab of an angular panel of a side panel member which projects out from a top of an adjacent display tray positioned below the bottom.
