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.

A collapsible food container, comprising a collapsible container and a lid assembly, the collapsible container including an upper portion, a lower portion, and a seating wall, the seating wall coupled to a first end of the upper portion and the lower portion coupled to a second end of the upper portion opposite the first end, the upper portion being collapsible as to transition the collapsible container between an expanded state and a collapsed state, the lid assembly including a rigid collar and a rigid lid, the rigid collar removably coupled to the seating wall of the collapsible container and the rigid lid removably coupling to the rigid collar.

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 parallelogram shaped box with side walls formed by parallel, generally rectangular bar members has a plurality of grommets inserted into the side walls between the bar members. Each grommet is trapped between adjacent bar members by clamping of adjacent bar members. Each grommet has a thickness greater than the thickness of the bar members and has a boss in the grommet with a pin retainer in the grommet, such as a straight hole. A pin placed in the pin retainer can support a decorative article so that external sides of the box can be decorated.

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.

The present invention relates to a disposable folding paper cup that folds flat and, when unfolded by the pressing of a folded portion, has a cylindrical upper end, the paper cup comprising: a cup body, which is made of a coated paper of which the inner surface is coated with a cup body coating layer, forms a cylindrical shape when unfolded, and forms a flat surface when both sides thereof are folded at folding lines; bending lines forming oval press parts that unfold bisymmetrically around each folding line when the folding line height center portion of the cup body is pressed, and dividing the oval press parts, spaced from the upper and lower ends of the cup body, therefrom; a bottom sheet which is a coated paper having a bottom sheet coating layer formed on the surface thereof so as to be fused with the cup body coating layer at the inner side of the lower end of the cup body, of which both ends are primarily fused therewith while the bottom sheet is folded along a transverse center folding line that is upwardly convex, and which is fused with the bottom edge of the folded cup body to form a bottom fused band; and fusion columns at which the front and rear surfaces, having the folding line at the center thereof, and the bottom sheet, having the end portion fitted therebetween, form a column shape higher than the fusion height of the bottom fused band and lower than the lower end of the bending line, thereby fusing, at a portion at which the bottom fused band and the folding line meet, the end portion of the bottom sheet through the three sides altogether.

An extendable electrical box comprises an electrical box having two open ends to an internal box space having a first depth. The electrical box comprises a mounting structure attached to at least one wall of the electrical box. The mounting structure is configured to mount the electrical box to a vertical wall structure such that the open end faces substantially parallel to the vertical wall structure. At least two extendable first rings each continuously surround one of the two open ends of the electrical box. The at least two extendable first rings are each slidably coupled with the electrical box via the sliding mechanical cooperation of one or more guides with one or more tracks, such that sliding either of the at least two extendable first rings in relation to the open ends of the electrical box expands the electrical box from the first depth to a larger second depth.
