摘要
The device consists of two separate parts: a stationary unit (12) which contains a motor (16) and vacuum pump (14), and a mobile head (20) with a power-supply switch for the motor and an aspirating nozzle designed to fit over the valve (32) in the lid of an airtight container (28, 30). The mobile head connects to the stationary unit with two flexible coaxial spiral cords, consisting of a hose (22) linking the vacuum pump and aspirating nozzle, and a power cord (36) linking the switch to the electrical motor. Both lines can easily be stretched together from the storage position, in which the mobile head sits on the stationary unit, to active mode, in which the suction effect keeps the mobile head coupled to the container.
