A packaging assembly includes first insulation blocks, second insulation blocks, and third insulation blocks, each insulation block arranged in contact with at least one other insulation block to define a void, the packaging assembly including at least one enclosure, the insulation blocks at least partially surrounded by the at least one enclosure.

In general, one aspect of the subject matter described in this specification is embodied in a rack system. The rack system includes a first stackable rack and a second stackable rack. The first stackable rack includes a top ceiling, a bottom surface, a first sidewall and a second sidewall. The second stackable rack includes a top ceiling, a bottom surface, a first sidewall, a second sidewall and a shelf. The top ceiling, the bottom surface, the first sidewall, the second sidewall and the shelf of the second stackable rack define a first compartment and a second compartment. The bottom surface of the first stackable rack is slidably coupled with the top ceiling of the second stackable rack.

An insulated thermal bag is provided, including an insulated thermal bag body, the insulated thermal bag body is mainly composed of an outer bag body and an inner container, wherein an upper end of the bag body is provided with a cover body, and the cover body is internally provided with a sponge layer, and the inner container is formed in integration by ABS resin and polyester insulation cotton. Compared with the prior art, the inner container and the bag body of the utility model adopt a detachable structure design, which greatly reduces the labor and consumption costs. In addition, the inner container of the utility model is formed in integration by ABS resin and polyester insulation cotton, which has good insulation effect.

A hard-sided cooler box may include a channel or cylindrical-shaped hole that extends from the outside of the cooler box to the inside of the cooler box. This cylindrical-shaped hole or channel may be covered/sealed by one or more latches of the cooler box when the cooler box is closed, and the latches are secured. However, when the latches of the cooler box are released, the cylindrical-shaped hole or channel may be unblocked, and the air from the interior of the cooler box can escape to the outside of the cooler box before the lid is lifted from the body. This allows the lid to be opened with no struggle.

A lockable food delivery box apparatus for preventing food tampering and contamination includes an insulated box defining a storage cavity configured to store food items for delivery. A box lid is selectively engageable with an open side of the insulated box. An electronic lock is coupled to the insulated box and is in operational communication with the box lid to secure and alternatively free the box lid. The electronic lock has a transceiver configured to be in operational communication with a smartphone. A heating coil is coupled to the insulated box to raise the temperature within the storage cavity. A cooling system is coupled to the insulated box to lower the temperature within the storage cavity. A power supply is coupled within the insulated box and is in operational communication with the heating coil, the cooling system, and the electronic lock.

Insert container for a shipment carrier, which insert container comprises at least one side wall and a bottom, which enclose a receiving space which can be closed with a lid, the at least one side wall and/or the bottom having a multilayer wall structure comprising at least one layer of at least one vacuum insulation panel and at least one layer of a particle foam, such as in particular expanded polypropylene (EPP), and wherein the at least one layer of particle foam is formed at each point with a thickness in the range from 2 mm to 12 mm.

Provided is a tumbler capable of controlling a temperature of an accommodated drink. The tumbler includes an inner cup for accommodating a drink, a frame which protects the inner cup, a heat conduction unit of which heat is exchanged with the inner cup through a lower surface and an outer circumferential surface of the inner cup to cool or heat the drink of the inner cup, and a control unit configured to control operation of the heat conduction unit. The thermal efficiency and ease of use of the tumbler are improved due to the configuration of the tumbler.

Provided is a cooling tank comprising a tank body in which a water accommodation space is formed, a foaming case for encompassing the outer peripheral surface of the tank body, and a foam insulating material formed by a foaming agent flowing into the foaming space between the outer peripheral surface of the tank body and the foaming case, and then foaming, wherein the foam insulating material is integrated with the tank body and the case through foaming, and the case has an air outlet through which air of the foaming space is discharged during a foaming process.

To improve the moldability and keeping cold performance of a vacuum heat insulating container. A constant temperature container includes a heat insulating container formed by disposing a core material between an outer cover material and an inner cover material and sealing the core material in a reduced-pressure state. The core material includes a first core material, the first core material being an organic substance made of open-cell foam, and a second core material having a lower thermal conductivity than the first core material at a vacuum degree of 100 Pa or less.
