A dispenser for discharging beverage can comprise a cock configured to control discharge of the beverage; a lever connected to a rotary shaft of the cock; a rotary valve connected to the rotary shaft and defining a rotary interspace configured to rotate together with the rotary shaft; and a fixed valve fixed to a cock body of the cock and defining a fixed hole configured to not move even when the rotary shaft is rotated; wherein the dispenser is configured to discharge the beverage when the lever is rotated to overlap a position of the rotary interspace and the fixed hole; and wherein the cock is configured to fix the fixed valve at one of a first position and a second position, the second position being different from the first position.

An embedded system controls an electric fluid valve, and the embedded system is connected to and receives overlooking images from an overlooking camera. It processes the images using a sequence labeling unit to tell if a fluid container is ready to receive and operates the valve accordingly.

In accordance with one aspect of the invention, a neoprene sleeve is provided that is sized to fit a jockey box cooler so that the sleeve extends between the bottom end of the container and the top of the container. The neoprene sleeve is resilient and covers the outer finish of the container, thereby protecting the container by inhibiting (e.g., preventing) dents and scratches to the outer surface of the container while covering up any existing dents and scratches so that they are not noticeable to the user.
