Disclosed herein are modular container systems having child-resistant containers, tray inserts and tray frames. Also disclosed are methods using the modular container systems and methods of storing substances in containers. The containers have a container base and a container cap and provide for child-resistant containers. A user can releasably remove the container cap from container base with a squeeze and lift sequence. For example, the user squeezes opposite sides of the container base, which releases a locking mechanism and allows for removal of the cap by lifting or pulling the container cap off from the container base. The components of the modular container system are modular and stackable. The modular system allow for organized, efficient, accessible and storage of the child-resistant containers. The modular container system also allows for easy counting, sorting and processing of the containers.

A storage system is provided that includes a stadium shaped bin having a bottom and an outer wall adjacent and extending from an outer edge of the bottom. The bottom and the outer wall defining an inner storage area. The bin having a plurality of legs located on a lower side of the bottom of the bin. The storage system further includes a lid having a raised top-hat portion about an upper surface and a skirt about an outer edge of the lid. The lid sized such that the skirt extends over the outer wall of the bin when the lid is placed on the bin, wherein the legs of the bin and raised top-hat portion of the lid are sized so that the legs nest about the raised top-hat portion of the lid when the bin is placed on the lid.

An erectable-type container having excellent durability is provided. The container 1 includes a bottom part 11, a side part 12 forming a box-shaped storage 1a with the bottom part 11, and a cross section appearing on a periphery 11a of the bottom part 11 is sealed with an insoluble sealing material which prevents moisture infiltration, and the side part 12 is adhered to the bottom part 11 by adhesive or the sealing material interposed between the cross section appearing on the periphery 11a of the bottom part 11. Further, the bottom part 11 is circular; and the side part is annular. Furthermore, the side part 12 is formed by engaging a belt-shaped body having an engagement protrusion 121 on one end and an engagement recess 122 on another end.

A modular stack includes a plurality of baskets including at least a first basket and a second basket. The second basket is configured to be stacked on the first basket such that the first and second baskets occupy a same footprint. The first and second baskets each include a base frame that is substantially rectangular. The first and second baskets also each include a bottom extending across a lower portion of the base frame. The first and second baskets also each include one or more cross-members extending over the bottom from a first side of the base frame to a second side of the base frame. The first and second baskets also each include a side plate extending upward from the first side. The side plate is connected to the base frame and the one or more cross-members.

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.
