An airtight device includes a container and an airtight cover on the container, and the airtight cover includes a fixing bracket, a door, and a pressuring handle. The fixing bracket has a through hole and a guiding slot, and the through hole communicates with internal space of the container. The guiding slot has adjacent first and second top surfaces, and the second top surface is higher than the first top surface. The door selectively covers the through hole. The pressuring handle pivoted on the door has a first section, a second section, and a rotating axis between the first and second sections, and the first section rotates relative to the second section. The second section receives a force to drive the first section to move from below the second top surface to below the first top surface such that the rotating axis pressures the door.

Systems and methods are disclosed for receiving, processing, and storing fish carcasses. A system comprises a conveyor apparatus, a grinding apparatus, a tank, a container, a refrigerating apparatus, and a power source. The power source may comprise at least one solar panel. The system may comprise a payment apparatus. The tank may be removable from the container. The system may be configured to loaded onto a truck. The system may indicate to a user that the tank is nearly full.

Systems and methods for an actively cooled container comprising: a power subsystem; an active cooling subsystem; and a control subsystem are provided. In some embodiments, the control subsystem is configured to: determine that additional cooling is needed; cause the active cooling subsystem to cool the actively cooled container below a lower limit; determine to end the additional cooling; and cause the active cooling subsystem to cool the actively cooled container at or above the lower limit. In this way, the best balance between a fast cooldown time and not damaging (e.g., through freezing) the product load (e.g., beverages), is achieved.

A storage container includes a container body having a storage space defined therein; and a container cover coupled to one side of the container body to open and close the storage space, wherein the container body includes: an inner layer forming an inner face of the container body defining the inner space; and an outer layer bonded to the inner layer and forming an outer face of the container body. The inner layer is made of titanium first material, and the outer layer is made of aluminum second material.

A method is provided for cooling a beverage in a container, the container being provided in contact with a cooling contact body thermally conductively coupled to a cooling element. The method comprises operating the cooling element and obtaining an ambient temperature of the environment outside the container and the cooling contact body. Based on the ambient temperature, a cut on temperature is defined and a temperature value indicative of a temperature of the beverage is obtained. The cooling element is operated if the temperature is larger than the cut on temperature until an end criterion is met. A higher ambient temperature may require more cooling of the beverage to ensure the temperature of the beverage is maintained between acceptable boundaries. A higher environmental temperature, requiring more cooling, means faster switching on or off. By using a switch on temperature based on the ambient temperature, more efficient cooling may be established.

For a beverage can having a lower portion, an upper portion and a greater diameter, a beverage insulation system for holding a beverage can includes a base with walls and a bottom that together form a base cup sized and configured to receive the lower portion of the beverage can; a lid with walls and a top that together form a lid cup sized and configured to receive the upper portion of the beverage can; a hinge assembly connecting the lid with the base to enable the lid to pivot between a closed position covering the upper portion of the beverage can received in the base cup and an open position uncovering the upper portion of the beverage can received in the base cup; and a generally cylindrical insert having an inner surface and being coaxially held within and by the lid cup to encircle the upper portion of the beverage can in the closed position.

A modular apparatus and system for managing the temperature of a livewell or other container housing water, and an associated method for installing the same. The system featuring a self-contained fluid line in communication with a first fluid line, which is in fluid communication with the livewell. The modular apparatus generally featuring the system and an enclosure. The enclosure can be located adjacent the livewell and detachably coupled to a fishing vessel. The modular apparatus and system can further comprise a condenser, which can be a forced air coil unit, a liquid-cooled unit, or a cold plate heat sink unit.

Systems and methods have demonstrated the capability of rapidly cooling the contents of pods containing the ingredients for food and drinks.

Disclosed is a beverage dispensing cooler. The beverage dispensing cooler includes a first lid, a second lid, a body, an axle, a handle and multiple hoses. The body includes a chamber, a panel, a base valve, a wall drain, a primary hose, a flow control unit, a power unit and a dispenser gun. The chamber includes multiple cylinders, multiple pressure compartments and a basin configured to collect water from condensation and melted ice. The axle further includes multiple wheels, a rod and multiple bearings connected to the rod and to the multiple wheels. The handle is configured to facilitate engagement of the beverage dispensing cooler with a hand of a user.

A Cornelius keg refrigerated storage, transport, and contents dispensing device holds the keg in the interior of a container equipped with provision for transporting the container, cooling the keg using refrigerated contact along the effective height of the keg, insulating the keg to maintain temperature, and storing the equipment for dispensing the keg contents.
