Patent ID: 10013897

Abstract:
The present invention relates generally to the field of registers (class 235) and more specifically relates to a laminated time tracking device system (subclass 488) and the method to make it. The invention is a novel label designed in different layers (laminated) to keep track of time. The inventor commonly refers to the apparatus for preventing objects from falling into a ridge hole as the: “Time Label “T-Label”. The T-Label disclosed in the instant application addresses the problem of communicating to a user an effective expiration date of a perishable good by providing a laminated structure comprising a bottom layer, a reactive layer, a sacrificial layer, a top layer, and a protecting layer; all assembled together. One of the novel aspects of the time tracking label disclosed in the present application is that it tracks the shelf life of a perishable good by looking at the Oxygen Transmission Rate (OTR) of the specific medium in which is stored thus providing a specific signal if a good has been oxidized rather than a “conventional” not verifiable expiration date.
