A container for storing associated articles, comprising: - a container base; - a first and at least a second container walls extending from opposing sides of the container base, the container base and the first and at least a second container walls at least partially defining the container the container having a container opening, wherein the walls extend upward from the base and terminate at a rim surrounding said container opening; - a first coupling member forming an interlocking recess within the first container wall; - a second coupling member forming an interlocking protrusion extending from the at least a second container wall, wherein the first coupling member is configured to match with the second coupling member for connecting the container in juxtaposed relation to a second container having the same arrangement of first and second coupling members (46, 42), with the container base of the first container being juxtaposed with the rim of the second container; - a third coupling member forming an interlocking recess within the first container wall; and - a fourth coupling member forming an interlocking protrusion extending from the at least a second container wall, wherein the third coupling member is configured to match with the fourth coupling member for connecting the first container in juxtaposed relation to the second container having the same arrangement of third and fourth coupling members (46, 42), with the container base of the first container being juxtaposed with the rim of the second container, wherein the first and second coupling members (46, 42) are equidistant from, in opposite directions, a centerline axis of the container, and wherein the third and the fourth coupling members (46, 42) are equidistant from, in opposite directions, said centerline axis, and wherein the first and third coupling members extend from the rim toward the container base, terminating before the container base, and the second and fourth coupling members extend from the container base toward the rim terminating before the rim, characterized in that the walls extend progressively outward as the walls proceed upwardly toward the rim forming a generally trapezoidal cross-section. - a container base; - a first and at least a second container walls extending from opposing sides of the container base, the container base and the first and at least a second container walls at least partially defining the container the container having a container opening, wherein the walls extend upward from the base and terminate at a rim surrounding said container opening; - a first coupling member forming an interlocking recess within the first container wall; - a second coupling member forming an interlocking protrusion extending from the at least a second container wall, wherein the first coupling member is configured to match with the second coupling member for connecting the container in juxtaposed relation to a second container having the same arrangement of first and second coupling members (46, 42), with the container base of the first container being juxtaposed with the rim of the second container; - a third coupling member forming an interlocking recess within the first container wall; and - a fourth coupling member forming an interlocking protrusion extending from the at least a second container wall, wherein the third coupling member is configured to match with the fourth coupling member for connecting the first container in juxtaposed relation to the second container having the same arrangement of third and fourth coupling members (46, 42), with the container base of the first container being juxtaposed with the rim of the second container, wherein the first and second coupling members (46, 42) are equidistant from, in opposite directions, a centerline axis of the container, and wherein the third and the fourth coupling members (46, 42) are equidistant from, in opposite directions, said centerline axis, and wherein the first and third coupling members extend from the rim toward the container base, terminating before the container base, and the second and fourth coupling members extend from the container base toward the rim terminating before the rim, characterized in that the walls extend progressively outward as the walls proceed upwardly toward the rim forming a generally trapezoidal cross-section.
