Description
Die Erfindung betrifft einen Gefrierwächter für tiefgefrorene Lebensmittel, bestehend aus einem mit Flüssigkeit gefüllten Milchglasröhrche-n, das susassnen mit- einerThe invention relates to a freeze guard for deep-frozen food, consisting of a frosted glass tube filled with liquid, which is connected to a Farbtablette in einen« durchsichtigen Kunststoffgehäuse eingelassen wird.Color tablet is placed in a transparent plastic housing.
Der Erfindung lisgi: die Auigabe zugrunde, insbesondere für gefrorene Lebensmittel eins bleibende Anzeige zu schaffen, die tfarauf hinweist, daß li-sr GefriervorgangThe invention is based on the task of creating a permanent display, particularly for frozen foods, which indicates that the freezing process unterbrochen ist oder war.is or was interrupted.
Diese Aufgabe wird erfindungänüäül^ dadurch gelöst, daß dem jeweiligen Gefriergut ein Gefrierwächter sichtbar beigepackt und mit dem Gefriergut eingefroren wird· Bei Lebensmittel, die in ihrer Mehrheit verpackt eingeThis problem is solved by the invention in that a freeze monitor is visibly packed with the respective frozen goods and frozen with the frozen goods. For foodstuffs that are mostly packaged, froren werden, kann der Gefrierwächter bereits in derfrozen, the freeze guard can be activated in the Verpackung enthalten sein. Dadurch ist auch das entfernen des Gefrierwächters vom Gefriergut nicht möglich, ohne dabei die Verpackung zu beschädigen. Während des Gefriervorgangs gefriert die in dem MiIchpackaging. This means that it is not possible to remove the freeze guard from the frozen food without damaging the packaging. During the freezing process, the milk in the milk freezes. glasröhrchen enthaltene Flüssigkeit (bei Lebensmittel wird in den meisten Fällen Wasser zum Einsatz kommen) zu Eis und bringt aufgrund der Ausdehnung das Röhrchen zum bersten. Taut die eingefrorene Ware wieder auf, schmilzt das EisThe liquid contained in the glass tube (in most cases water is used for food) turns into ice and the expansion causes the tube to burst. If the frozen goods thaw again, the ice melts im Gefrierwächter und löst die Farbtablette auf, diein the freeze guard and dissolves the color tablet, which Flüssigkeit wird farbig. Der im gefrorenen Zustand farblose Gefrierwächter ist jetzt farbig und liefert den bleibenden Beweis, daß das Gefriergut aufgetaut ist bzw. war. Selbst wenn die Ware nochmals eingefroren wird, bleibtLiquid becomes colored. The freeze guard, which is colorless when frozen, is now colored and provides permanent proof that the frozen goods have been or are thawed. Even if the goods are frozen again, the color remains die Einfärbung erhalten.receive the coloring.
Beschreibung:Description:
Dadurch kann zuverlässig ausgeschlossen werden, daß unsachqemäö ^alageries Gefriergut aus Verbraucher gelangt. Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß This reliably prevents improperly stored frozen goods from reaching the consumer. The advantages achieved with the invention are in particular that
a) der Gefrierwächter unsachgemäße Handhabung von Gefriergut sichtbar macht bei deren Verzehr gesundheitliche Störungen auftreten könnten.a) the freezing monitor makes improper handling of frozen goods visible, the consumption of which could cause health problems.
b) der Verbraucher mit Hilfe des Gefrierwachters sofort erkennen kann, ob die gefrorene Ware (Lebensmittel) an- oder aufgetaut ist bzw. war.b) the consumer can immediately tell with the help of the freezer monitor whether the frozen goods (food) have been or are partially thawed.
c) der Handel mit Hilfe des Gefrierwächters Hinweise über eine evtl. unterbrochene Kühlkette bzw. defekte Gefriergeräte bekommt. c) the retailer receives information about a possible interruption in the cold chain or defective freezers with the help of the freezing monitor.
d) der Gefrierwächter anzeigt, daß eine vorgegebene Temperatur überschritten wurde, die zum Verderb des Gefriergutes führen kann.d) the freezing monitor indicates that a specified temperature has been exceeded, which could lead to spoilage of the frozen goods.
e) der Gefrierwächter aufgrund seiner verwendeten Materialien einfach und billig zu produzieren ist.e) the freeze guard is simple and inexpensive to produce due to the materials used.
Die beigefügten Zeichnungen zeigen den Gefrierwächter in zwei Ausführungen in bezug auf seine Form.The attached drawings show the freeze guard in two versions with regard to its shape.
