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.

A beverage system is provided that includes a cup having a frustoconical wall extending from a first end to a second end. The first end is coupled to a bottom wall and the second end defines a rim. Inner surfaces of the walls define a cavity. The rim defines an opening that is in communication with the cavity. A lid is coupled to the rim such that the lid covers at least a portion of the opening. A sleeve includes a collar that surrounds a portion of the frustoconical wall. The sleeve includes first and second arms. The arms each include a first end coupled to the collar and an opposite second end. The second end of the first arm directly engages the lid. The second end of the second arm directly engages the second end of the first arm when the second end of the first arm directly engages the lid to prevent the lid from being removed from the cup.

A cap for a fluid container includes a main body, an actuator ring slidable along the main body and having an annular groove, and a plurality of latches having secure and release states and that may be placed in the release state by contact with the actuator ring. A closure system for a fluid container includes the cap, and a lip attached to a fluid container that is engaged by the latches of the cap. The lip may be integral with a fluid container or part of an adapter that is connected to the fluid container. A method of automated handling of a container includes engaging an annular groove of an actuator ring of a cap using a robotic arm, driving the actuator ring, and removing the cap from the container. The method may further include transporting the container via engagement of the robotic arm with the cap.
