Abstract: An apparatus for communicating the status of a consumable includes a sleeve with a tubular housing. The tubular housing has a lumen with a proximal section and a distal section separated by an internal flange. The sleeve includes a battery case or power module with a coaster coupled on the proximal side of the internal flange, an electronic module and a power supply module coupled to the distal side of the internal flange. A sensor in the form of a spring-loaded switch is located on the coaster to trigger and enable a status indicator based on a predetermined weight of a beverage container. The status indicator is an LED light source or wireless signal coupled to the sensor through the electronic module.
