| titleOfInvention | Vapor permeation time-temperature indicator device, method of manufacture and application thereof |
| abstract | A time-temperature indicator (t-T indicator) is described which is useful for monitoring the shelf lives of various perishable articles. The device is constructed of a vapor-permeable barrier (4) positioned between a vapor and an indicator (5), both housed in a vapor-impermeable container (3). The device is activated just prior to the monitoring period by providing vapor to the container, as for example, by rupturing a solvent-filled frangible reservoir (7). The indicator, upon contact with the vapor produces a visual color response, and the vapor is constrained to permeate through the vapor-permeable barrier before contacting the indicator. thus creating a characteristic induction period before a color response occurs. The time required for the color response to occur in the device is a function of the temperature and time. The induction period can be varied by the thickness and type of material of construction used for the vapor-permeable barrier, the nature of the vapor and the nature of the indicator employed. |
