The inventive vacuum storage container incorporates a top cover with vacuum valve and bottom base with an elastic seal. Furthermore, the bottom base possesses removable bottom which couples to the bottom base to form a second interior storage cavity. The removable bottom base may also be coupled with a display surface.

Systems and methods for providing compostable food containers which preserve the quality of a food product for an extended duration of time, and which optionally allow for cooking of the food product therein. In some implementations, the food containers are sturdy, stackable, insulating, and require minimal or no manual labor to assemble. In some implementations, the food container includes a base and a cover which cooperate to form a closed chamber for supporting, protecting, insulating and optionally cooking a food product, such as a pizza. The base and cover may each be formed of a single layer of material including, but not limited to, molded sugarcane fiber (“bagasse”), molded wood fiber, molded bamboo fiber, molded paper or plastic.

A stackable container, including a body and a cap threadingly engageable with a neck portion of the body and having a vaulted interior and a top portion formed with a frustrum-shaped depression for snap-registered engagement with a base portion of a counterpart of the body, the cap further including handle projections and a skirt. Opposite stop structures prevent rotation of the cap relative to the body beyond predetermined threaded engagement; a detent releasably captures the body in the predetermined threaded engagement. A base portion of the body having inclined side walls facilitates rotation of the body with respect to the cap. The skirt guides the body into alignment with the cap. The base can have four of the side walls forming a square, the containers of a stack having any of four relative orientations. A consumable product such as a cosmetic can extend into the cap from the body.

Embodiments of this disclosure include a rigid tray container and methods and equipment for using the rigid tray container in batched process operations. In one embodiment, a mass container is sized and dimensioned to receive one or several rigid tray containers. In other embodiments, equipment is configured to lid/unlid, secure, stack, load/unload, and buffer rigid tray containers. In other embodiments, equipment is configured to stack and stage mass containers. In some embodiments, methods are provided for batch processing items.

A stackable case includes a cooling and/or heating device, such as a Peltier element, so that the stackable case can be used as a cooler and/or warmer for storing beverages, food, etc. A power source device, in which a plurality of battery packs is housed, supplies power to the Peltier element and one or more fans. The power supply device has latches for detachably joining or linking it to the stackable case in a stacked manner.

A pot or pan lid is configured for stacking with identical or differently sized lids that have an identical handle or knob with a dimple on the upper surface. The side of the lid opposite the handle has a complimentary protrusion configured to stably engage the dimple. The edge of the knob may extend laterally to correspond with the lid curvature to also support a similar lid on the knob perimeter that is distal from the dimple. The engaged central dimple and more distal perimeter of the knob provide for stable stacking of a plurality of lids in a level arrangement that avoids one or more lids tipping over.

A container system having a base and a lid. The base has a bottom and one or more sidewalls extending from the bottom to define an interior volume, the base having a rim at a peripheral edge of the one or more sidewalls, the rim defining a first engagement region. The system also has a lid having a peripheral outer rim defining a second engagement region, the first and second engagement regions dimensioned to releasably engage with each other. The lid has a hinged region having a first hinge about which the lid folds as a first part of the lid is lifted from the base to disengage portions of the first and second engagement regions from one another, to provide access to the interior volume of the base while a second part of the lid on an opposite side of the hinge remains secured and attached to the base.

A foldable container includes a bottom, side walls that can be folded in, a lid, a closure element that can be moved relative to the lid, at least one first closure element mating piece, and at least one second closure element mating piece. The at least one second closure element mating piece is provided on a portion of the side walls that faces the bottom and/or on the bottom in such a way that, in a storage position of the lid, the at least one second closure element mating piece can interact in a form-fitting manner with the closure element in order to lock the lid in the storage position with the side walls folded in.

The present disclosure provides a battery box and a vehicle, the battery box comprises an upper box body, a lower box body, a connecting member, a fixing member. The upper box body comprises a first eave portion, the lower box body comprises a second eave portion. The first eave portion is provided with a first connecting hole, the second eave portion is provided with a second connecting hole and a mounting hole. The connecting member passes through the first connecting hole and the second connecting hole to connect the upper box body and the lower box body. The fixing member passes through the mounting hole to make the lower box body mounted to external equipment, compared with the conventional battery box, the lower box body is equivalent to the arrangement of eliminating the third eave portion, it simplifies the structure and reduces the weight, thereby improving the energy density.

A food carrying system comprises a plurality of food service items including at least one container and optionally one or more plates, drink carriers, and/or trays. At least one of the food service items includes opposing strap openings formed in an edge, encircling flange, or opposed flange handles thereof. A support band encircles the stack, passing through the strap openings, and ends thereof are affixed together to stabilize the stack and in embodiments providing a hand-hold for carrying the stack. The band can further extend through a strap opening provided in a separate handle, so that the stack can be carried using the handle. Strap openings can be provided on lids and/or bases of the containers. Strap openings can be closed ovals, or can be C-shaped, having open outer edges. Band ends can be joined by adhesive, hook-and-loop, knot tying, stapling, snaps, buttons, etc.
