A tool container system includes a first tool container and a second tool container. The first tool container has a first base, a first cover pivotably attached to the first base by a first hinge portion, a first base locking member coupled to the base, a first cover locking member coupled to the first cover, and a first latch coupled to the first base and moveable between a first unlocked position in which the first cover is movable relative to the first base between a closed position and an open position, and a first locked position in which the first latch engages the first cover locking member and the first cover is locked to the first base in the closed position. The second tool container is stackable on the first cover of the first tool container and having a second locking member. When the second tool container is stacked on the first tool container, the second tool container is lockable to the first tool container when the first latch is moved to the first locked position to engage both the first cover locking member and the second locking member.

The present disclosure provides a storage box, including a bottom, a first side wall, a second side wall, a third side wall and a fourth side wall. The first side wall, the second side wall, the third side wall and the fourth side wall sequentially surround the bottom. The first side wall is parallel to the third side wall, the second side wall is parallel to the fourth side wall, the first side wall is perpendicular to the second side wall, a first notch is disposed on the first side wall, a second notch is disposed on the second side wall, a width of the first notch is larger than or equal to a thickness of the second side wall, a width of the second notch is larger than or equal to a thickness of the first side wall.

An adjustable length container that includes an inner container section and an outer container section that fit telescopically together to enable the length of the container to be adjusted. The bottom and side walls of the outer container section include at least two sections so that one of the sections can be removed to shorten the total length of the container. The container optionally includes a removable end wall on the outer container section, a removable and length-adjustable partition in the inner container section and complementary features that permit multiple containers to be securely stacked.

A paint package lid (14, 114) includes a base wall (54) having a lid base wall upper surface (56) and a lid base wall lower surface (58), a container coupling rim (60) disposed radially outwardly with respect to the base wall and having a rim upper surface (62), and a closure well (64, 164) disposed radially inwardly with respect to the base wall. The closure well includes a radially outer wall (82) extending downwardly with respect to the base wall, a lower wall (84) extending radially inwardly with respect to the radially outer wall and establishing a lowermost surface (85) of the lid, and a neck (86, 186) disposed radially inwardly with respect to the radially outer wall and extending upwardly from the lower wall and having a closure coupling (95). Also disclosed is lid and closure assembly and a paint package (10, 110, 210) including the lid.

A stackable box (1) for accommodating and for transporting articles and for stacking in a stacking direction (2) with at least one other box (1) of the same type, wherein the box (1) has a base (3) and a side wall (4), which projects beyond the base (3) and surrounds the base (3) at least partially, wherein the base (3) and the side wall (4) together bound an accommodating space (5) for the articles, wherein the side wall (4) contains at least two, spaced-apart adapters in order for the box (1) to be gripped mechanically by means of at least one gripping device (6), said adapters in the side wall (4) being designed in each case in the form of channels (8) which extend longitudinally in a longitudinal-extent direction (7) running parallel to the stacking direction (2), wherein the channels (8) each have an entry opening (9) and an exit opening (10) and, therebetween, an inner channel cavity (12) which is bounded by a channel-boundary wall (11) of the box (1), extends longitudinally in the respective longitudinal-extent direction (7) and through which the gripping device (6) is guided.

One example of a nestable-stackable wider-based disposable container is composed of a plastic-coated paper frustoconical tube having its wider end edge connected continuously to the mouth of a plastic bag whose capacity is larger than the tube size. For storage, let the wide end of one container to receive the narrow end of another container. The plastic bag of the former is forced to push up inwardly and to cleave tightly to the paper side wall, allowing the later to be compactly nested into the former. For usage, one stands a container on its non-tipping wider end, places items in via its upper narrower opening, discards it as a whole unit when done. Other examples are described and shown.

The invention relates to a container assembly comprising a container for depuration of mollusks and a drain canal unit. The assembly provides a closed circulation of water via a circulation route that has an entry portion between the floor of the container and the drain canal unit, a circulation channel between the corner of the container and a drain canal unit, and a drain canal within the drain canal unit. Also provided is a drain canal unit for use in stackable containers that provides circulation of water within a container assembly.

A paper cup and a method of forming the same. The paper cup may include a sidewall and a floor portion that collectively define a cavity. In one aspect, the paper cup may include a rim that is coated with a rigid shell that encapsulates the rim. In another aspect, a void defined by a rim of the paper cup may be filled with a rigid filler material, and the rigid filler material may be one that expands upon application of heat thereto. In yet another aspect, the paper cup may include a separate rim component that is attached to the sidewall. The separate rim component may be formed from molded pulp fibers, and it may include a flange portion that is attached to the sidewall and a rim portion that protrudes from the sidewall.

A self-locking assembly includes one or more shelves. Each of the shelves has dividers, which define storage bays that are adjacent to each other in a lateral direction and adjacent storage bays being spaced apart from each other by one of the dividers positioned therebetween, and a lock contained within each storage bay. The self-locking assembly also includes one or more storage units having a width that is a same as, or smaller than, a width of at least one of the storage bays. Each of the storage units has an upper surface, which transports item(s) supported thereon, and an interlocking feature that engages with the lock of one of the storage bays to resist removal of each storage unit from a corresponding one of the storage bays. Each storage unit can be inserted into and removed from a corresponding one of the storage bays in a longitudinal direction.
