Abstract

The barcode (3) includes at least one region which changes character with temperature so that the barcode can be read by a scanner (4).

Description

528 976 2 Detta har enligt uppfinningen emåtts därigenom, att åtminstone ett av streckkodens streck .gagn u oc oo o o o ø nu nu o nu I 0 I I är utfört att ändra karaktär under inverkan av en temperaturändring på ett sätt, som medger indikering med en streckkodläsare. Streckkoden kan vara anbragt på en förpackning för livsmedel eller på ett rnatberedningskärl innehållande livsmedel. Genom uppfinningen kan en indikering av uppnådd temperatur erhållas med hjälp av streckkoden, och med flera streck utförda på det temperaturkänsliga sättet kan flera temperaturgränser fastläggas. Främst är streckkoderna av reversibelt slag, så att stigande och fallande temperaturer kan indikeras. Det är även möjligt att alternativt eller dessutom använda streckkoder, som är irreversibla, så att en indikering kan erhållas beträffande den högsta temperatur, som exempelvis ett livsmedel har utsatts fór innan det når fram till kassan, där det följaktligen kan utsorteras om temperaturen någon gång har varit för hög. Åtminstone en del av streckkoden kan utgöra en instruktion för en lämplig matberednings utförande, vilken instruktion är avläsbar medelst en till en matbehandlingsapparat kopplad streckkodläsare. 528 976 2 According to the invention, this has been achieved in that at least one of the bars of the bar code .gain u oc oo ooo ø nu nu o nu I 0 II is designed to change character under the influence of a temperature change in a manner which allows indication with a bar code reader. . The barcode may be affixed to food packaging or to food preparation containers. Through the invention, an indication of the temperature reached can be obtained with the aid of the bar code, and with fl your lines executed in the temperature-sensitive manner, temperatur your temperature limits can be determined. The barcodes are mainly of a reversible type, so that rising and falling temperatures can be indicated. It is also possible to alternatively or additionally use bar codes, which are irreversible, so that an indication can be obtained regarding the highest temperature, for example a food has been exposed before it reaches the checkout, where it can consequently be sorted out if the temperature has ever been too high. At least a part of the bar code may constitute an instruction for the execution of a suitable food preparation, which instruction can be read by means of a bar code reader connected to a food processing apparatus.

Uppfinningen avser även användningen av en streckkod, som är utförd att ändra karaktär under inverkan av en temperaturändring å ett sätt, som medger indikering med en streckkodläsare, varvid streckkoden är anbragt på ett objekt, som värmebehandlas i en apparat styrd under medverkan av en i apparaten inbyggd streckkodläsare.The invention also relates to the use of a bar code which is designed to change character under the influence of a temperature change in a manner which allows indication with a bar code reader, the bar code being applied to an object which is heat treated in an apparatus controlled with the participation of an in the apparatus. built-in barcode reader.

Uppfinningen är närmare tydliggjord i det följande under hänvisning till bifogade ritning, som schematiskt visar ett utföringsexempel på en streckkod enligt uppfinningen i figur 1 och användningen av streckkoden tillsammans med en streckkodläsare i en mikrovågsugn i figur 2.The invention is further elucidated in the following with reference to the accompanying drawing, which schematically shows an embodiment of a bar code according to the invention in Figure 1 and the use of the bar code together with a bar code reader in a microwave oven in Figure 2.

Streckkoden i fig.l är anbragt på en förpackning för livsmedel och är visad som en avdelning a, som utgör den streckkod, som på känt sätt identifierar livsmedlet och på likaledes känt sätt styr en lämplig matberedningsprocedur. Proceduren innefattar ett antal bestämda temperaturgränser, och dessa är fastlagda genom streckkoderna enligt uppfinningen i en avdelning b, som ändrar karaktär allteftersom de bestämda temperaturerna uppnås.Såsom nämnts tidigare är det viktigt att livsmedel inte överskrider högsta tillåtna temperaturer, och för detta ändamål är förpackningen försedd med en avdelning g, med streckkoder, som är av det irreversibla slaget. När dessa indikerar en för hög temperatur kan förpackningen avskiljas exempelvis i en afiärs kassa i samband med den rutinmässiga avläsningen av streckkoden och dessutom hemma i köket efter inplaceríngen av förpackningen i en mikrovågsugn.The bar code in fi g.l is placed on a package for food and is shown as a section a, which constitutes the bar code which in a known manner identifies the food and in a similarly known manner governs a suitable food preparation procedure. The procedure includes a number of fixed temperature limits, and these are determined by the bar codes according to the invention in a section b, which change character as the determined temperatures are reached. As mentioned earlier, it is important that food does not exceed the maximum permissible temperatures, and for this purpose the package is provided with a section g, with barcodes, which are of the irreversible kind. When these indicate an excessively high temperature, the packaging can be separated, for example, in a one - year box in connection with the routine reading of the bar code and also at home in the kitchen after placing the packaging in a microwave oven.

Fig.2 visar användningen av en mikrovågsugn l, ívilken en förpackning 2 för livsmedel är inplacerad med en streckkod enligt uppfinningen belägen fi-arnfór en streckkodläsare 4, som är 528 976 3 inbyggd i ugnen. Objektet som skall behandlas kan alternativt utgöras av ett matberedningskärl 5, som är försett med en lämpligen påklistrad streckkod 3. Streckkoden avläses, och om streckkoden g indikerar en för hög temperatur matas förpackningen ut ur ugnen. I annat fall startar behandlíngsproceduren styrd av streckkodema a och b, vars signaler leds från streckkodsläsaren 4 till ugnens styrenhet 6.Fig. 2 shows the use of a microwave oven 1, in which a package 2 for food is placed with a bar code according to the invention located in front of a bar code reader 4, which is 528 976 3 built into the oven. The object to be treated may alternatively consist of a food preparation vessel 5, which is provided with a suitably affixed bar code 3. The bar code is read, and if the bar code g indicates a too high temperature, the package is fed out of the oven. Otherwise, the processing procedure starts controlled by the bar codes a and b, the signals of which are routed from the bar code reader 4 to the control unit 6 of the oven.

Streckkoden är tryckt direkt på förpackningar eller matberedningskärl eller på fiån en karta överföringsbara etiketter e.d. med kompletta streckkoder för olika program. Härför användes någon typ av värmekänsliga färger, exempelvis termokroniatisk tryckfärg, som finns i marknaden eller som är under utveckling för andra ändamål.The barcode is printed directly on packaging or food preparation containers or on a map transferable labels e.d. with complete barcodes for different programs. For this purpose, some type of heat-sensitive inks were used, for example thermocronical printing inks, which are on the market or which are being developed for other purposes.

Uppfinningen är självfallet inte begränsad till de här beskrivna och visade streckkoderna och dess användning utan kan modifieras på åtskilliga sätt inom ramen för den i patentkraven definierade uppfinningen. Streckkoderna i fig.1 kan således ha de olika avdelningarna integrerade med varandra för minskat utryrnrnesbehov. Uppfinningen kan även användas vid etappvis tining av djupfrysta livsmedel eller för värmebehandling av andra objekt än livsmedel Vidare kan streckkoder för olika, valbara program med olika temperaturgränser för styrning av fortsättningen av programmen vara anbragta på olika sidor eller ställen på förpackningar eller rnatberedningskärl för att möjliggöra en snabb modifiering av önskat program .The invention is of course not limited to the barcodes described and shown here and its use, but can be modified in several ways within the scope of the invention as claimed in the claims. The barcodes in fig.1 can thus have the different departments integrated with each other to reduce the need for equipment. The invention can also be used for step-by-step thawing of frozen foods or for heat treatment of objects other than food. Furthermore, bar codes for different, selectable programs with different temperature limits for controlling the continuation of the programs can be placed on different sides or places on packages or preparation vessels. fast modification of the desired program.
