Provided is a utility connectivity system. More specifically the presently claimed subject matter is directed to connectivity systems associated with containers and utility units connectable to one another.

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.

A container includes a base, a lid, and a hinge that connects the base and lid. The containers may be configured to be vertically stackable in an closed position and still permit venting via vents in the lid of each container. The containers may also be nested in an open position with indentations in the base to facilitate separation of the containers. The indentations may be in one of two positions with an alternating pattern when the containers are in the nested arrangement.

A container set includes a cover, a base, the cover having a cover sealing member which is made of elastic material and protrudes from a cover peripheral edge of the cover to allow the cover to engage the base, and a first container received between the cover and the base and having a container edge to allow the first container to engage an inner surface of the cover. In addition, the inner surface of the base has a base groove to allow the cover sealing member to engage the base groove when the cover engages the base, wherein the container edge, the cover sealing member and the base groove constitute an interlocking structure. With this interlocking structure, the cover, the base and the container(s) located therebetween can form a tightly engaged container set.

The present invention discloses a storage box cover and a storage box used therewith. The storage box cover is covered on a storage box body which is fixedly connected with a clamping convex ring on a bottom end surface; the top edge of a cover body is annularly provided with a clamping groove; the bottom end surface of the cover body is annularly provided with a buckle; the top circumference of the cover body has a downward turnup; a ring groove for clamping the top of the storage box body is formed between the buckle and the turnup; and the buckle can be adapted and clamped in the clamping groove to complete the stable stacking of a plurality of storage box covers; the top of the cover body is fixedly connected with a limiting flange for limiting the storage box body.

A stackable container for stacking over an identical base container. The stackable container comprises: a top including a receiving surface and a neck; a bottom including a resting surface and a clearance surface raised relative to the resting surface, the resting surface being adapted to rest on the receiving surface of the base container, and the clearance surface providing clearance for a neck of the base container; and a sidewall joining the top and the bottom to define a room in the stackable container. The sidewall includes a first wall and a second wall parallel to each other and respectively located on a first side and a second side of the stackable container, each sidewall including: an external face; and a handle defined by a shaped surface extending inwardly from the external face to a floor portion isolating the handle from the other side of the stackable container.

A stackable container includes a solid compostable or recyclable body formed primarily of a plant fiber. The body includes a floor and a plurality of side walls that are coupled to the floor along first common edges. Each side wall is coupled to two adjacent side walls along second common edges to surround an interior space of the container. A top surface of the side walls provides a rim that includes a recess or projection configured to couple the container to a corresponding projection or recess of an overlying container. A bottom surface of the floor includes a recess or projection that is configured to be coupled with a projection or recess of an underlying container.

A bottom surface member of a container defines an xy-plane, and a side surface member defines an xz-plane and aan yz-plane. A protective member includes a receiving part that has a first receiving surface parallel to the xz-plane and a second receiving surface parallel to the yz-plane, and a supporting part formed with the receiving part. The supporting part has a first flat plate section parallel to the xz-plane, a second flat plate section parallel to the yz-plane, and a third flat plate section parallel to the xy-plane. The receiving part has a fourth flat plate section that has the first receiving surface and is parallel to the xz-plane, a fifth flat plate section parallel to the yz-plane, a sixth flat plate section facing the fourth flat plate section with a gap therebetween, and a seventh flat plate section that has the second receiving surface.

A thermally insulating packaging to hold an item includes a solid compostable or recyclable shell that is formed primarily of starch, and a bottom cover. The shell includes a floor, a plurality of inner side walls that are coupled to the floor, a rim coupled to the plurality of inner side walls, and a plurality of outer side walls that are couple to the rim. The floor and the plurality of inner side walls define an interior space of the shell to receive the item and an opening to the interior space. The plurality of inner side walls and plurality of outer side walls have a space therebetween that defines a gap. The gap can be an air-filled cavity, or be filled with a compostable or recyclable core material.

Systems and methods for nesting product packaging with strainer inserts are provided. Product packaging systems may include, for example, a product container with a lid and with a strainer insert disposed within the container. In some embodiments, the strainer inserts may be snapped into place in a channel, groove, or other retention feature of the parent container, thus permitting coupling without the use of adhesives or fasteners. The strainer inserts, when coupled within the parent containers, may define a drainage volume in which product fluids may drain to maintain the product separately from the fluids, e.g., to prolong shelf-life of the product.
