rungs- apparatus for storing and monitoring of aging and temperature-sensitive products

The invention relates to a device for storing and monitoring of aging and temperature-sensitive products in a storage container.

Perishable materials such as food and pharmaceutical ma-products, but also other biological elements or systems, such as organs, sperm and the like that have to be maintained vital to be provided at the time with information about their state of health or their life or their expiration dates, this information being obtained by items of information of various kinds and stored. Commonly known are printed on food or pharmaceutical products expiration dates, and also other data carriers, such as bar codes, magnetic strips, electronic storage elements or suchlike are conceivable. DE 198 03 208 AI, a sensor is disclosed, for example, with the current state of use and age can be determined. This sensor is a time-temperature indicator, which is designed as a time-temperature integrator and photochromic properties on the basis of

having transfer reactions. Due to the properties of the indicator photochro- men / integrator can be photo-induced by exposure to a particular energy range Phototen color, wherein subsequent to the dyeing, a time and temperature dependent

Discoloration occurs. Such a sensor is reversible, that is, the indicator reaction allowed after or during the decolorization a renewed photo-induced coloration. Since these known sensors in the REFERRED TO INTERCHANGEABLY invention play an essential role, the disclosure of DE 198 03 208 is included in the disclosure of the invention.

Starting from the aforementioned prior art, the invention has for its object to provide an apparatus for storing and monitoring of aging and temperature-sensitive products in a storage container, which allows to check the aging state of the respective product in the storage container reliably and monitor without checking the product itself.

This object is solved by the features of the main claim.

By specified in the dependent claims, advantageous developments and improvements are possible.

Characterized in that the storage container is a signal capture and control unit, a transmission unit for transmitting the information of the information elements to the signal detection and control unit and a display unit is associated with each piece of information about the state of aging and / or the service life of the products from the can information elements are transmitted to the signal detection and control unit that manages the information and monitored, wherein a display unit may display the respective state or remote transmission can. This is a complete control and monitoring of individual products in a simple manner.

As information elements both sensors for detecting the state of aging as well as disk and memory elements of various kinds can be used. Particularly advantageous is the use of a photo / thermochromic sensor is based on a proton transfer mechanism, such as is disclosed in DE 198 03 208 and intended to be part of this application. However, it is possible in a known way, electronic, magnetic, and other storage elements.

The transfer unit comprises advantageously optical and / or magnetic and / or electronic reading arrays on, can be used to scanning the information elements of the accommodated in the storage container products and / or read and can be transferred to the signal detection and control unit Ü.

Similarly, the transmission unit to at least one optical and / or magnetic and / or electronic writing array functions with the information can be transferred to the information elements. In this way, for example, the transmitter may be initiated sor 198 03 208 by optical irradiation in accordance with DE.

Both the transfer unit and the elements of information itself can transmit and / or receiving means for transmitting the information between items of information transmission unit and signal detection, and control unit have.

Preferably, the sensor unit is disposed the read / write unit, the signal detection and control unit and the display unit in close proximity or on or in the storage tank, but it is also conceivable that only the sensor unit with the modules 2, 3 and 4 are arranged in the storage container and in that the signal detection and control unit located elsewhere.

Advantageously, a plurality of production are ten with information elements arranged in a storage container, in which case means for locating the position of the products in the container are provided to the display unit. For example, a mat- rixförmige display may be provided, in which case the storage container has a similar matrix-like structure, so that each area of ​​the display has a correspondence in the compartment of the storage container.

The storage tank may be formed as a cooling container jeg- Licher type then, the invention can be used in large stationary cooling systems in mobile refrigeration systems, in refrigerators and freezers, and with any cooling device or thermostat.

Through the invention, products can be introduced at different times and thus have different dene start and expiry dates, are safely monitored.
