One or more support platforms for a modular system are provided. The support platforms are configured to detachably support and optionally couple with utility modules in a system, such as modular tool storage units. The support platforms include one or more components, such as shelves and/or top panels, that include couplers configured to coupled to modular tool storage units.

A custom hair coloring container, components of the container, and method of use and doing business. In one embodiment, the container includes a container body, a hair colorant container section of the container body removably mountable to a peroxide container section of the container body, and the hair colorant container section and the peroxide container section collectively forming a cavity with an inside surface. The hair colorant container section may include a first interior seal threadedly engaged with the inside surface within the hair colorant container, and the peroxide container section may include second interior seal threadedly engaged with the inside surface within the peroxide container section.

A modular travel storage system for transporting liquids, gels, and powders, includes: a holder portion with a plurality of container receptors, including left, right, rear, and top walls, with left, right, and rear inner ledges; and a plurality of container pods, each including a container body with left, right and rear protruding rims, and a lid; such that each container pod slides into a corresponding container receptor.

A screen basket for the preparation of medical instruments. The screen basket having a substantially rectangular base area and an open upper side. The screen basket including: a first container part and a second container part, the first container part and the second container part each being open at an end face and each comprise a screen-like wall, the first container part being configured for insertion into the second container part; and at least one locking pin configured to be pushed through each of two or more push-through openings provided in one or more of the first container part and the second container part, the at least one locking pin selectively locking the first container part and the second container part together in at least two different positions with respect to each other.

A modular travel storage system for transporting liquids, gels, and powders, includes: a holder portion with a plurality of container receptors, including left, right, rear, and top walls, with left, right, and rear inner ledges ; and a plurality of container pods, each including a container body with left, right and rear protruding rims, and a lid; such that each container pod slides into a corresponding container receptor.

Provided is a modular storage container system, kit, and method of using that includes standardized panels, joining protrusions, rods and corner blocks to form a durable multi-functional modular storage.

An adapter for a cooler assembly is provided that is configured to extend the capacity of a cooler assembly. The adapter includes a hollow cylinder with an outer wall, an inner wall, a top edge, and bottom edge. The hollow cylinder has a first section that is threaded on the outer wall to receive a collar of the cooler assembly. The hollow cylinder has a second section that is threaded on the inner wall to receive a body of the cooler assembly. In some arrangements of the invention, a shoulder on the outer wall is positioned between the first section and the second section. On the inner wall, a slanted section is positioned between the first section and the second section.

A modular tank comprises one or more wall modules coupled together and one or more liner bags supported by the one or more wall modules for the containment of liquid, in particular water. The wall modules can be planar or curved and the edges of the wall modules are coupled together via joining members. The modular tank comprises one or more layers of the wall modules. One or more of the wall modules comprise a hole and the one or more liner bags, which can be coupled together, comprise one or more parts that protrude through the holes in the wall modules to support the liner bags.

A container system comprising a hollow body defined by a continuous outer peripheral wall having a first cavity and a second cavity opposing the first cavity and separated by a dividing wall, a neck opening into the first cavity and a wider open mouth at the end opposing the neck for receiving a base container therein having a lid that engages the inner surface of the outer peripheral wall to secure the base container in the mouth and substantially seal the second cavity.

A modular shipping container includes a layer of two side pieces positioned against sides of a component of several components with a same width. The side piece include pegs protruding from a top of each side piece and bottom openings in a bottom of each side piece sized and positioned to conform to the pegs. The container includes one or more end pieces on the same layer as the side pieces. Each end of the end piece is shaped to attach to an end of a side piece and is shaped to maintain a width between the side pieces. A length of an area formed by the side pieces and end pieces is sized to accommodate a maximum length of each component. The components have a height that is an integer number of standard units and a height of the side pieces matches an integral number of the standard units.
