A container system and a method for forming a knob in a container. The container system includes a container, in particular a medical or surgical sterile container preferably having a tub-like container vessel and/or a container cover; at least one separate coupling element; and at least one coupling system for releasably connecting the coupling element to the container. The coupling system includes a male coupling portion formed on the container and a female coupling portion formed on the coupling element. The coupling portions can be coupled to and uncoupled from one another. The male coupling portion is integrally formed in a wall of the container and is designed as a protruding knob having an undercut.

Certain aspects of the present disclosure provide a modular container, including: six sides, wherein: each side of the six sides of the modular container comprises at least four surface connectors, each surface connector of the at least four surface connectors comprises at least two connector elements, at least one connector element of the at least two connector elements is of a first type, and at least one connector element of the at least two connector elements is of a second type; and an access door in at least one side of the six sides.

Provided is a utility module including a base portion and a top portion and having a front side and a back side with a locking path extending between the front side and the back side. The top portion is configured at a back portion thereof with at least one back locking bar and at a front portion thereof with at least one front locking bar extending parallel to said back locking bar. The base of the utility module is configured at a back portion thereof with a back bar coupling recess facing towards the back side and having a back under-bar arresting surface and a front bar locking arrangement comprising a front facing barrier wall and a locking lever comprising an arresting tongue extendable in front of said barrier wall and having a front under-bar arresting surface.

An Artist's implement container and base mount having a plurality upper hexagonal cells with a recess therein. The cells have double parallel linear hooks and single linear lips and a coupling strip, with a hole there through. There is a plurality of lower hexagonal cells with a recess therein. The lower cells have plurality of double parallel linear hooks and single linear lips and a coupling strip, with a hole there through. Lastly, there is a base mount comprising a base portion and a bayonet connector.

Described herein are various coupling systems to be used with storage units that are selectively coupled and decoupled. The coupling systems may be used with storage units that are stackable and/or transportable, thus allowing the storage units to function well within a large stationary environment, such as a basement, and also for a subset of the storage units to be selected and easily moved to another location.

Implementations disclosed and claimed herein provide a customized storage system. In one implementation, a folding crate movable between a storage position and a collapsed position is provided. The crate may include a first frame end of a crate having a first frame, a second frame end having a second frame disposed opposite the first frame, and a base panel fixed to and extending between the second frame. The crate may include swinging panels that are releasably secured to the second frame when the crate is in a storage position and rotatable about a swinging axis at the first frame to move the crate into a collapsed position. The crate may also include folding panels pivotally mounted to the first frame and the second frame that are foldable along a folding axis when the crate moves into the collapsed position.

A drinking vessel storage container combination is provided herein. The combination comprises: a first body; a first cap demountably coupled to the first body; and a storage container demountably coupled to the first body opposite the first cap. The first cap comprises a lid, a port, and a strainer. The storage container comprises a second body, a second cap, a panel, and an insert. The first body is hollow, open-faced, and substantially cylindrical in shape. The bottom face is configured to allow the storage container to be demountable affixed thereto. The strainer is positioned adjacent to the port and within the chamber when the first cap is demountably affixed to the first body. The insert is selectively positioned within the second body. The panel is selectively positioned on top of the insert. The second cap is demountably affixed to the second body and the bottom face.

A separable multi-dispenser assembly is provided. The dispenser assembly may include a geometric shape that may be divided and separated into two or more secondary geometric shapes, with each secondary shape including a separate dispenser unit each with an inner volume and a dispenser head. The multi-dispenser assembly may be formed as a rectangular prism that when separated provides two right-angled triangular prism shaped secondary dispenser units.

A linkable child-proof safety container that includes corresponding slide locks.

Disclosed is a multiple purpose connectable member. The connectable member may be used and operated to seal or close a container. The connectable member may further be operated to connect a plurality of the connectable members together. A plurality of the connectable members may be connected in various combinations and/or geometries.
