Patent ID: 7442935

Claim:
A device for analyzing the composition of the contents of a container comprising: a channel ( 20 ) for receiving a container, which channel comprises a lower portion tilted downwards away from an open front face of the channel through which a container is introduced so as to define a concavity directed upwards, and non-destructive analysis means ( 40 , 50 ) associated with this channel, wherein the non-destructive analysis means ( 40 , 50 ) comprise: means ( 40 ) for emitting/receiving an electromagnetic field at least at several frequencies comprised in a determined frequency range, means ( 50 ) capable of measuring the complex impedance of emitting/receiving means influenced by the load formed by the container (R) and its contents, representative of the complex dielectric characteristics of the container and of its contents, and means ( 50 ) capable of providing a piece of information related to the measured complex impedance and consequently, to the nature of the contents of said container.
