Abstract
Description
Die Erfindung betrifft eine Vorrichtung auf Lebensmittelverpackungen, für vorzugsweise Tetrapacks, aber auch Flaschen, Tüten und ähnliches, insbesondere welche Milch beinhalten. Die Vorrichtung zeigt an, ob der Inhalt noch unverdorben und somit noch genießbar ist.The invention relates to a device on food packaging, for preferably tetra packs, but also bottles, bags and the like, especially some Include milk. The device indicates whether the content is still unspoiled and therefore still enjoyable is.
Recherchen der Erfinder ergaben, dass anscheinend keine Vorrichtung in derartiger oder ähnlicher Art und Weise existiert.Research by the inventors revealed that apparently no device in such or similar Way exists.
Das Problem, welches der Erfindung zugrunde liegt, ist, dass Milchverpackungen über ein aufgedrucktes Mindesthaltbarkeitsdatum verfügen, dieses hat aber nur bei ungeöffnetem, unversehrtem Zustand der Verpackung Bedeutung. Nach dem öffnen der Verpackung ist z.b. uperisierte (ultrahocherhitzte) Milch (H-Milch) im Kühlschrank bestenfalls nach fünf Tagen verdorben, ohne Kühlung kann es möglich sein, dass sie bereits nach einem Tag nicht mehr genießbar ist (abhängig von der aktuellen Witterung). Bei pasteurisierter Milch ist der Zeitraum sogar noch kürzer.The problem of the invention is based on the fact that milk packaging has a printed best before date feature, but this has only with unopened, intact condition of the packaging meaning. After opening the Packaging is e.g. supererized (ultra-high temperature) milk (UHT milk) in the refrigerator at best after five days spoiled without cooling could it be possible, that it is no longer edible after just one day (depending on the current weather). For pasteurized milk, the period is even shorter.
Nun kann es vorkommen, dass Verbraucher, welche einen nur geringen Milchkonsum haben, die Übersicht, wann eine Verpackung geöffnet wurde, verlieren. Ob die Milch noch genießbar ist, lässt sich zwar durch umständliche Hausmittel wie beispielsweise das ausflocken verdorbener Milch in Kaffee, oder auch eine Geruchsprobe, deren Ergebnis oft zweifelhaft ist, feststellen.Now it can happen that consumers, which have a low milk consumption, the overview of when a packaging open would lose. It is difficult to determine whether the milk is still edible Home remedies such as flaking out tainted milk in Coffee, or even a smell sample, the result of which is often doubtful is notice.
Durch die in den Schutzrechtansprüchen aufgeführten Merkmale hingegen, wird eine absolut sichere und einfache Überprüfung auf einen Blick möglich. Gleichzeitig wird eine eventuelle Beschädigung der Verpackung deutlich gemacht.By the features listed in the property right claims however, is an absolutely safe and easy check on a look possible. At the same time, any damage to the packaging becomes apparent made.
Mit der Erfindung wird erreicht, dass über ein in die Verpackung integriertes Anzeigefeld, farblich dargestellt wird, ob die Milch noch genießbar ist. Dieses Anzeigefeld wird zweckmäßigerweise im unteren Bereich der Verpackung angebracht, da gerade bei halber oder viertelter Füllhöhe einer angebrochenen Verpackung, der Zustand nicht einwandfrei festgestellt werden kann. Das Anzeigefeld kann eine sehr geringe Größe haben, weniger als 1 cm² ist vollkommen ausreichend. Bei verdorbener Milch schlägt die Farbe des Anzeigefeldes um.With the invention it is achieved that about a display field integrated in the packaging, shown in color becomes whether the milk is still edible is. This display field is conveniently located in the lower area attached to the packaging, especially at half or quarter Level one opened packaging, the condition is not correctly determined can be. The display panel can be a very small size is less than 1 cm² perfectly adequate. The color beats when the milk is spoiled of the display panel.
Dies wird möglich, da der ph-Wert frischer Milch nahezu im neutralen Bereich von circa 7 liegt, der von verdorbener hingegen im leicht saueren von unter 7. Aufgrund dieser saueren Reaktion ist es technisch ohne weiteres möglich, mittels eines geeigneten Indikators den gewünschten Farbumschlag zu erzeugen.This becomes possible because the pH of fresh milk almost in the neutral range of around 7, that of spoiled however, in the slightly acidic of less than 7. Because of this acidic It is technically easily possible to use a suitable reaction Indicator the desired one To generate a color change.
Die mit der Erfindung erzielten Vorteile liegen insbesondere in der einfachen Anwendung, der hohen Zuverlässigkeit, sowie der kostengünstigen Herstellung, welche in der Praxis durchaus in einem Verhältnis zum Nutzen steht.The advantages achieved with the invention are particularly easy to use, high reliability, as well as the inexpensive Manufacturing, which in practice is quite in relation to the Benefit stands.
