A vacuum insulator (10) includes: a core (13); a pressure sensor (51) that detects a pressure; a transmitter (52) that transmits, by wireless communication, the detected pressure detected by the pressure sensor (51); a power feeder (53) that feeds electric power to the pressure sensor (51) and the transmitter (52); and an outer skin (14), an inside of which is decompressed, the outer skin (14) accommodating therein the core (13), the pressure sensor (51), the transmitter (52), and the power feeder (53), the outer skin (14) having gas barrier capability.

The disclosure provides a vacuum storage tank, comprising a vacuum storage tank body. The vacuum storage tank body is provided with a storage cavity and a pressure release channel in communication with the storage cavity. The pressure release channel is provided with a pressure release structure, the pressure release structure includes a pressure release cylinder, and the pressure release cylinder is placed in the pressure release channel. The pressure release cylinder includes a manipulation part and a sealing member for blocking a port of the pressure release channel, and the manipulation part extends from an outer wall of the vacuum storage tank body. A reset retaining structure is arranged between the pressure release cylinder and the vacuum storage tank body to control the pressure release cylinder so that the sealing member keeps blocking the port of the pressure release channel.

A vacuum storage system (40) for storing an article, comprises a sealable outer chamber (30) and a sealable inner chamber (20). The sealable outer chamber (30) has an evacuation valve (21) for connection to a suction device (48) for evacuation of said outer chamber (30). The sealable inner chamber (20) is adapted to receive said article and has a one-way valve (13) in communication with the outer chamber (30). The one-way valve (13) is adapted to open upon the application of suction to the outer chamber (30), thereby to enable evacuation of said inner chamber (20), but to close upon discontinuation of said suction.

The present application describes a thin-walled single-serve perishable food container configured to be economically manufactured from metal and useable by a consumer in the existing single-serve metal container, for example, a disposable single-serve metal yogurt cup. The thin-walled container has a top flange coupled to a bottom with a cylindrical wall and a conical sidewall that extends inwardly from the top flange, such that a diameter of the bottom is less than a diameter of the top flange. The thin-walled container may house other foods, such as ground or pulverized organic or synthetic powdered mixtures or dried food. The container may also have a cover or lid that hermetically seals the contents.

This application is directed to a Wireless Controlled Locking Jar with Integrated Vacuum Pump. More particularly, this application provides a wireless controlled lock on a jar lid having a built-in electrically powered vacuum pump and lid gasket which acts to lock the jar from unauthorized access by pulling a vacuum within the jar making it impossible to open the lid. The locking jar may be used to keep contents secure and fresh, and also out of the reach of children or other unauthorized individuals as it employs the user's Wi-Fi connected or Bluetooth paired smartphone or other device, in combination with a smartphone or other device software application, to lock and open the jar and allow access to the contents inside. By using the paired device and software application, the jar may be locked and unlocked by the user from any location.

A transportable slurry box includes a structure comprising an interior to contain a cuttings slurry; a door movable between a closed position and an open position to provide access to the interior of the structure, wherein the door is located within a top surface of the transportable slurry box; a mechanical bay in the structure; and a heating unit removably mounted within the mechanical bay of the transportable slurry box for heating the cuttings slurry within the interior.

Disclosed is a vacuum compartment structure for a cup lid and a manufacturing method thereof. The vacuum compartment structure for a cup lid includes a stainless steel cylinder body and a compartment upper cover. The compartment upper cover is covered on the cylinder body and has an inwardly recessed shape, and the compartment upper cover and the cylinder body are fixedly connected and sealed by laser welding. The compartment upper cover and the cylinder body form a vacuum chamber, which has a getter therein. The compartment upper cover is arranged with a plastic upper cover layer, an outer surface of the cylinder body is wrapped with a plastic lower cover layer, and the plastic upper cover layer is combined with the plastic lower cover layer to fasten and wrap the compartment upper cover and the cylinder body.

A food storing and tracking system comprising: at least one food container; at least one sealing lid, each complementary to one of said at least one container; a vacuum seal inducer, and sensors for measuring freshness of the food item, wherein the system is configured to allow: placing the food item in the container; releasably sealing the container with the sealing lid complementary thereto; subjecting the sealed container to sub-atmospheric pressure by employing the vacuum seal inducer on the sealed container, and tracking the freshness of the food item with the sensors for measuring freshness.

A transportation system for semiconductor substrates includes a tray, lid and packaging bag. The tray includes a bottom and circumferential sidewalls. The tray has an opening on a top side and is configured to receive semiconductor substrates through the opening, the substrates being stacked onto each other in the tray in parallel to the tray bottom. The lid includes a cover plate and at least two arms extending from the plate. The arms are configured to be inserted into the tray between the tray sidewalls and the semiconductor substrates. The cover plate is configured to cover the tray opening when the lid is fully mounted to the tray. The packaging bag is configured to enclose the tray with the substrates stacked therein and lid arranged thereon, and to be evacuated of air and sealed such that the tray and lid arranged in the bag are vacuum sealed inside the bag.
