A coupling mechanism for a utility system is provided, the coupling mechanism coupling an object with a modular system, such as a modular storage system. The coupling mechanism includes arms that extend from a projection. The arms are configured to engage under ribs within the modular system, such as the modular storage system.

A modular pastry packaging carousel is disclosed which provides the ability to individually store wedge-shaped pastry slices in a respective wedge-shaped pastry module. In a version of the application, the modular pasty packaging carousel generally comprises a bottom plate, a top plate, a spacer positioned between the bottom plate and the top plate providing a radial gab therebetween; and a plurality of wedge shaped pastry modules, each comprising a sector-shaped removable base. The sector-shaped removable base includes a means for engaging the pastry module with the base tray radial connection channels.

A user friendly twist and lock telescoping tubular package includes tubular package pieces with built-in visual cues assisting a user in the proper assembly and operation of the package, and with improved engagement features opposing improper operation of the package while facilitating proper use of the package. Improved locking features are more resistant to inadvertent unlocking or repositioning of the package. Support and stability features enhance the locking connections and improve reliability of the locking connections.

Various aspects of the disclosure generally relate to a collapsible storage container with multiple sleeves. In some implementations a two-sleeve variant is described. In some implementations a three-sleeve variant is described. Both variants may be used to contain appropriately sized and shaped objects, for example bread, maps, posters, blueprints, plans, etc.

A foldable container includes a foldable supporting frame, at least one operation switch arranged on the foldable supporting frame, and a container body supported on the foldable supporting frame. The operation switch is actuated through a pulling operation to move the foldable supporting frame between an unfolded mode and a folded mode. The container has an edge and an opening formed within the edge. At the unfolded mode, the opening is opened. At the folded mode, the opening is closed. The container body is automatically folded as the foldable supporting frame is moved from the unfolded mode to the folded mode. Via a folding method, the foldable supporting frame is folded to reduce an overall size for occupying less storage space when it is not in use.

A container assembly having an expandable insulated container and an expandable insert. The insert includes an open upper rigid portion having side panels and a lower rigid portion having side panels a bottom panel, and the upper and lower rigid portions are joined by a flexible medial portion.

A fluid collection container includes a self-supporting, collapsible bag with a threaded cylindrical inlet ring or spout and a strainer removably seated within the ring. The strainer can separate a macroscopic solid object from a viscous liquid. The fluid collection container includes a rectangular prismatic box with the spout extending through and a threaded cap removably coupled to the spout. A method of draining automotive oil includes positioning the bag beneath an oil pan of an automobile, removing an oil plug from the automotive oil pan and allowing the oil plug to fall into the strainer; draining the automotive oil through the strainer into the bag; removing an oil filter from the automobile; removing the strainer from the inlet; inserting the oil filter; and screwing a threaded the cap onto the inlet.
