A lid for an insulated container comprises a flexible gasket configured to facilitate a seal between the lid and an inner wall of the insulated container, and further configured to expand into an interior compartment of the insulated container responsive to a vacuum developing in the interior compartment. A diaphragm chamber is situated opposite the flexible gasket from the interior compartment when the lid is fully engaged with the insulated container. One or more air channels couple the diaphragm chamber to an exterior of the lid. The development of a vacuum in the interior compartment of the insulated container draws a force on the flexible gasket, thereby reducing pressure in the diaphragm chamber. The negative pressure in diaphragm chamber is back-filled with external air, which enters the lid via the air channels. The lid may then be removed without excessive vacuum forces.

Container assemblies are described herein that include a metal closure and a container including a plastic finish. The container assemblies may be characterized by improved performance including reproducibility of force needed to remove the closure. Furthermore, the container assemblies described herein may be compatible for use with hot-fill packaging processes.

Examples described herein relate to a mixing vessel for consumable substances, a method of using a mixing vessel and a method of manufacturing a mixing vessel. The mixing vessel may be used to produce a consumable liquid, such as a hot beverage. In one example, a mixing vessel for consumable liquids has an internal chamber for receiving consumable substances for mixing and a sealing member for the internal chamber. The sealing member has at least two stable spatial configurations to change a volume of the internal chamber. The sealing member is arranged to transition between the at least two stable spatial configurations on application of a pressure generated within the internal chamber during mixing to increase the volume of the internal chamber.

A container cover for storage container includes a rotary device, an outer cover member, an inner cover member, a first guide block, second guide block, a pumping piston and a piston seat so arranged that when the rotary device is driven by a user to rotate the first guide block, guide rods of the first guide block are moved along a first continuous wave-shaped track of the second guide block, causing the second guide block and the pumping piston to move alternatively up and to further pump air out of the storage container through an air-pimping hole of the piston seat to create a negative pressure. Further, a first spring member an upper rail seat can be provided to balance the movement of the pumping piston and to stabilize the rotation of the first and second guide blocks. A relief valve rod can be selectively used for giving a visual indication indicative of the presence of a negative pressure in the storage container.

The present invention provides a closure for a hot-fill container comprising: a cap member having a top surface, a bottom surface, and a wall portion having an outer surface and an inner surface wherein the inner surface comprises threads to mate with a threaded neck finish of a hot-fill container; a flexible diaphragm member comprising: at least one flexible portion in a first position and a sealing lip portion to seal a liquid in the container thus preventing the liquid from traveling to the threaded neck finish of the container; and a disc member interposed between the cap member and the diaphragm member, wherein the disc member comprises: a hydrophobic filter membrane and at least one vent providing a path for air to travel from an area near the threads to the hydrophobic filter member, wherein the flexible diaphragm member flexes to compensate for a change in pressure within the container by transitioning downwards in response to a decrease in pressure and/or by transitioning upwards in response to an increase in pressure.

A system and method for determining and communicating the status of a sealable container. The system comprises a seal status detection component that is positioned adjacent to or on a lid comprising a deflectable component. The lid engages the sealable container to form a seal. The seal status detection component moves between a first state of operation where there is a gap between the seal status detection component and the deflectable component of the lid, and a second state of operation where the seal status detection component is adjacent to or in contact with the deflectable component of the lid. The seal status detection component has a first frequency response to interrogation by a reader when the seal is intact, and a second frequency response when the seal is broken.

The present invention relates to a system for processing milk, which comprises a thermal pasteurization device and an autoclaving treatment device. The raw milk is sequentially subjected to thermal pasteurization and autoclaving treatment to obtain milk which can be transported by a long distance. The present invention has the beneficial effects that the method for processing milk of the present invention is used for extending the service life of the pure milk and improving the storage capacity thereof; the short service life reduces the influence on the nutrient composition and flavor of the milk; the obtained milk has a taste closer to the fresh raw milk, and the storage time is longer; after thawing to restore the liquid state, the shelf life can be up to 21 days; the milk processed by the method of the present invention can be used for transporting by a long distance.
