Patent ID: 8094014

Claim:
Packaging for storing a substance having a physicochemical property which may change between a time when said substance is introduced for a first time into the packaging and a later time when said substance is used, said packaging comprising: a main body receiving and storing said substance; a closure member selectively allowing and preventing access to the substance stored in the main body; a first sensor arranged in contact with the substance stored in the main body for delivering a first signal representing a first measurement of the physicochemical property of the substance stored in the main body at said later time; a second sensor exposed to an exterior of the packaging for delivering a second signal representing a second measurement of a physicochemical property of a cutaneous surface of a user at said later time; a display member for generating visual information representing at least one of said first measurement and said second measurement; a processing unit for conditioning at least one of the first signal and the second signal, for displaying the visual information by the display member, and for operating on at least one of the first signal and the second signal for checking that the stored substance is fit for use by the user at the later time, wherein said checking comprises checking that the substance is compatible with the physicochemical properties of the cutaneous surface of the user at the later time; an electric power source for supplying said first sensor, said second sensor, the display member and the processing unit.
