Time tracking labeling system and method to make it
First Claim
1. A label for tracking the passing of time and communicating an expiration signal to a user comprising:
- (a) a bottom layer;
(b) a reactive layer;
(c) a sacrificial layer; and
(d) a top layer;
where each of said bottom layer, said reactive layer, said sacrificial layer, and top layer is a rectangular prism;
where said bottom layer, said reactive layer, said sacrificial layer, and top layer are assembled consecutively one over the other one in their horizontal orientation;
(e) Oxygen impermeable protective layer.

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.

18. A method to produce a label for tracking the passing of time and communicating an expiration signal to a user comprising a bottom layer, a reactive layer, a sacrificial layer, a top layer, and an oxygen impermeable protective layer including the steps of:
-
a. entering a set of information into a central processing unit that controls pump via electrical circuitry; b. activating pump to c. withdraw one of the chemicals contained respectively in separate chemical reservoirs; d. regulating the flow of each chemical via a valve controlled by Central Processing Unit by means of electrical circuitry; e. delivering the chemical to a drop generator through tubing connection; f. generating drops of the selected chemical; g. orienting the drops of the selected chemical by having them passing in between high voltage plates controlled by central processing unit via electrical circuitry; h. distributing the drops of the selected chemical on support member to i. generate the label by alternating appropriate layers of the different chemicals. - View Dependent Claims (19)
