Definitions

  • the invention relates to a device / method for monitoring the temperature of a product, in particular a product, a product or a fluid, to produce a display upon reaching a certain inadmissible temperature range, with at least one component separated by a separating layer, which meet in particular when emerging two components generate / generate an optical change as an indication of the impermissible temperature range.
  • a device for detecting an elevated temperature is known to monitor the storage conditions of frozen food.
  • the device has a membrane, which separates two visually interacting with each other indicator (components) and becomes permeable to rising temperature, so that when the two substances meet a visual display.
  • the object of the invention is to improve a device / a method of the type mentioned above so that the device may be exposed to such high temperatures before attaching to the monitored good that exist in the unacceptable temperature range.
  • Such a device is activated only after first reaching the permissible temperature range (or shortly before), so that only then the device is in a state in which it emits an indication when leaving the permissible temperature range and thus upon reaching the impermissible temperature range.
  • Such a device can thus during manufacture, transport and attachment to a good, especially a product, readily be constantly in the high impermissible temperature range, so that production and handling are much easier. Even during production and / or during the packaging of a good, the device can be installed or attached.
  • Fig. 3 is a section through a second embodiment.
  • the device consists of two, separated by a release layer 2 paper towels, which are each impregnated with a chemical component 3, 4.
  • This device is surrounded by a plastic envelope 1, so it is the individual components not possible to react with each other.
  • the components 3, 4 or the impregnated paper towels freeze when falling below a defined by use of NaCl and the molar formula temperature between 0 0 C and -10 0 C in the paper towels.
  • the separating layer 2 can be removed manually, automatically or chemically, without the two components 3, 4 touching the soaked paper towels and showing an optical reaction.
  • a frozen product which is provided with a device according to the embodiment, can now be checked at any time by visual inspection for compliance with the cold chain.
  • the device according to the invention and the method according to the invention are therefore characterized by the fact that the device can be independently activated in such a way that it reaches the temperature range at which it reaches the temperature range only after the temperature has first been reached at which the product, product or fluid / it is stable for a long period of time, in particular conserved, the device starts monitoring.
  • the device is activated or armed only after the first reaching the allowable, preferably low temperature range or on the way to this allowable range, and only then can the device take over its task of monitoring. Until this / this activation / arming of the device, this can thus be easily located in impermissible temperature ranges, especially produced at high temperatures, transported, stored and attached.
  • Fig. 3 shows a separating layer 2, which encloses a space on all sides, which is filled by a component 3, wherein the other component 4 is located outside of the space 2.
  • This device works in a similar way as described above, d. H. as soon as the separating layer 2 forming the closed space has become permeable, the two components 3 and 4 can react with one another and produce a display.
  • the apparatus shown in Fig. 3 still has a third embodiment with a different operation, which is described as follows:
  • the separating layer 2 is formed by a plastic material or a glass, which is destroyed at a higher pressure inside the room.
  • the separating layer 2 encloses an aqueous liquid, in particular water, on all sides, so that when a temperature below 0 ° C. is reached, the liquid 3 expands and destroys the container 2. But since the liquid 3 is still in the frozen state, it does not get outside of the separation layer 2. Only after the device has reached temperatures in which the water in the frozen state in a liquid state and thus melted, it can be outward go to component 4 to soak them. Since the water or the aqueous liquid is preferably colored, so this leakage and watering from the outside is visible, since the plastic cover 1 is designed to be transparent.
  • the partition 2 or the plastic material or the glass is opaque, so that the colored liquid 3 is not visible, as far as it has not leaked.
  • the component 4 located outside the space 2 thus only needs to absorb the liquid and can thus be a simple granular material.
  • the component 4 may be formed only by an empty space or a gas-filled space, since it is sufficient that the colored Liquid leaks.
  • the second component may also be formed only by a space in which the first component penetrates.
  • Additions to the liquid or to the water ensure that the liquid does not freeze just below 0 ° C, but only at lower temperatures, in particular in a range between -5 ° C and -10 0 C, so that the activation temperature range exactly is determinable.
  • the permeability of the release layer 2 can thus be done not only chemically, but also in other ways. Most recently, an overpressure generated by freezing water was described. But it is also possible to make the separating layer 2 mechanically permeable, in particular to puncture, wherein a bimetal, a memory material or an expanding plastic or metal or a coated material is used.
  • the device may be part of a price tag, label, packaging or sticker. It is also possible to change a computer-readable code, in particular a bar code, by the device in such a way that the code is unreadable and thus a clearly visible display is created.
  • the optical display of the device can be done by a gradual or continuous color change according to the prevailing temperature. Also, by the property of the memoriy metals, this separation can take place more or less automatically and can be returned to a straight position, for example, from an angled position to the reverse conversion effect, so that the mixture and / or reaction of the two components is carried out. Furthermore, an RFID transponder, which contains the date of manufacture and various other information, can be integrated into the device, in particular in this coolant label. This makes it possible to store important data.
  • the advantage is the monitoring when turning the coolant labels in the color change by increasing the temperature by means of video, which are arranged over refrigerated counters or the location of the goods or components and generate a signal in conjunction with alarming components or forward the signal to the appropriate personnel.
  • the release layer is preferably a plastic film from the group of polyolefins or polypropylenes whose composition is adjusted so that it becomes permeable at a certain (desired) temperature.

Abstract

La présente invention concerne un dispositif / un procédé pour surveiller la température d'une marchandise, en particulier d'un article, d'un produit ou d'un liquide, de sorte que lorsqu'une plage de températures inadmissible déterminée est atteinte, une indication est produite, l'invention faisant intervenir au moins une composante séparée par une couche de séparation, qui, à l'émergence, en particulier lors de la rencontre de deux composantes, produit/produisent une variation optique pour indiquer la présence de la plage de températures inadmissible. Selon l'invention, la couche de séparation reste imperméable sur la plage de températures inadmissible et devient perméable sur la plage de températures admissible; les composantes produisent une indication lorsqu'elles se rencontrent sur la plage de températures inadmissible alors que la couche de séparation est perméable, et elles ne produisent pas d'indication lorsqu'elles se rencontrent sur la plage de températures admissible alors que la couche de séparation est perméable.
