Methods and apparatus for removably or irremovably interconnectable building block containers such as those capable of initially storing consumable items such as food and drink. After consumption of the food or drink, the cavity containing same may be cleaned and/or refilled with consumable or non-consumable items. The building block containers are utilized as building block toys and may be manufactured or otherwise designed to be collectable. In one aspect, the container connectors are nearly identical such that any one connector may mate with any other connector. In another aspect, the connectors are nearly identical but the orientations of each connector vary to allow mating to occur when the connectors are properly oriented. In another aspect, the container is a cube juice box with connectors on all four corners of all six sides of the container. A frame for holding a juice container may also be utilized.

A set of connectors connects buckets, such as five-gallon buckets, to each other, to the ground, to dimensional lumber, and/or to pipe for the purpose of producing objects such as benches, stepstools, tables, sawhorses, shelters, platforms, etc.

The Invention is a standard set of round, cylindrical and spherical pieces that form objects to hold other objects and food, to transport things and to build modular elegant and beautiful constructions. For example, the Invention's pieces can be used as spherical flowerpots that are arranged along a walkway with flowers, and those same flowerpots can be stacked to support a flowerpot a few feet off the ground. Furthermore, the flowerpots can be stacked to form columns that vines grow on. Pieces can be made exponentially larger and smaller, and features on pieces can also be made exponentially larger and smaller, while maintaining compatibility within the system of Invention pieces. For example, the stacked boxes that are FIG. 33 can be elongated to stack in a manner that forms the pattern of a standard brick wall's interlocking pieces.

A coupling for assembling at least two beverage cans together, comprising at least a pair of collar portions, each to slidably receive a corresponding end region of one of the beverage cans, the collar portions being configured to engage the beverage cans for associated games and/or other amusement activities.

A modular bottle closure comprises one or more exterior surfaces defining a hollow interior, a plurality of spaced engagement elements outwardly protruding from the exterior surfaces, a bottle cap interface element formed within the interior, and a coupling section coinciding with, or recessed from, a terminal edge of the closure. The coupling section frictionally engages engagement elements of another closure, whereby to couple together one or more closures. The plurality of engagement elements, which may protrude from the upper surface, are arranged by regions. A side of each engagement element of a region defines a locus of contact surfaces of substantially equal shape and length as the perimeter of the selected coupling section portion.

A cap for a spout of a thin-walled flexible package which has a flattened head having a viewing region, at least one left tooth and at least two right teeth is provided. The at least one left tooth is suitable for being inserted with interference into a right housing to form a first joint and build a modular structure particularly appealing to children.

An apparatus is provided having an open configuration and a closed configuration. The apparatus includes, while in the closed configuration, a first panel, a second panel, a third panel, a fourth panel, a fifth panel, and a sixth panel that together create a box partially enclosing a void space. The first panel is rotatably coupled to the fifth panel and the sixth panel, the second panel is rotatably coupled to the fourth panel and the sixth panel, and the third panel is rotatably coupled to the fourth panel and the fifth panel. The apparatus opens from the closed configuration to present the contents therein through a single degree-of-freedom mechanism where the first, second, and third panels become perpendicular to the fourth, fifth, and sixth panels while the fourth, fifth, and sixth panels become aligned in a same plane.

Building block container is a modular hollow building block that may be used to build a wall, shelter, structure, building, greenhouse, water filtration device, emergency shelter, pipeline, flood blockade, floodwall, dock, or raft. Building block container has a special design so that they are reversibly attachable to each other without fasteners. Building block container may also be used as a container to hold any type of liquid or solid contents. A plurality of building block container may be shipped to a disaster area, third world location, or anywhere with people in need, while filled with water or food, where the water or food may be consumed by those in need and then the empty building blocks may be used to build a wall, shelter, structure, building, etc. One or more building block containers may also be used as a water filtration device to filter unclean water into drinkable water.
