Definitions
- the handling of the article from the producer to the consumer includes a plurality of different steps, such as storage (long term as well as short term storage) , transhipments, transports as well as handling in the shop.
- storage long term as well as short term storage
- transhipments transports as well as handling in the shop.
- rules and recommendations how the temperature of the goods should be supervised and documented during these different phases, but in practice said rules are difficult to completely observe. If the individual article at some point of time by misadventure, or in another way, would be exposed to a higher temperature than the recommended highest desired value, neither the consumer nor the other parties in the chain between producer and consumer can see this on the proper package.
- the desired value is +6 °C. It should also be pointed out that the problem with unintentional temperature rises is not limited only to food-stuffs. Thus, also other goods, such as medicines, photographic film, and the like, may lose its quality in the same way.
- the present invention aims at managing the above-mentioned problem. Therefore, in a first aspect, the invention aims at providing a package from which may be read whether the package temporarily has been exposed to an inappropriate tem- perature. In another aspect, the invention aims at providing a temperature indicator, which, for the same object, may be connected to packages, i.e. to indicate whether the package has been exposed to an inappropriate temperature.
- Figs 1-3 are schematic perspective views showing three packages with different temperature indicators according to the invention
- Figs 4 and 5 are partial side views of a package, one and the same temperature indicator being shown in two different functional states, Fig 6 is a very enlarged front view showing the temperature indicator in the state according to fig 4,
- Fig ' 7 is an analogous front view showing the indicator in ' the state according to fig 5
- Fig 8 is a cross-section through the temperature indicator according to figs 6 and 7.
- Figs 1-3 schematically illustrate three packages 1 for storage of an article in a temperature-decreased, preservative state, in which the article should have a certain desired value, e.g. -18 °C, if the article is deep-frozen.
- a temperature indicator 2 is connected to the package, said indicator comprising means, which preserves a certain property. when the temperature of the article is decreased towards and past a predetermined limit value which is at least somewhat higher than said desired value, but which alters this property in an irreversible way if the temperature during storage would rise to or above said limit value.
- said means may initially be trans- parent and arranged to retain the transparency thereof during temperature reduction past said limit value and said desired value, but be converted to an irreversibly opaque state if the temperature would rise above the limit value.
- figs 6-8 illustrate a concrete example of a temperature indicator according to the invention.
- two different casings are included, viz. an outer casing 3 and an inner casing 4, which has the purpose of separating a first liquid mixture 5 from a second liquid mixture 6.
- the inner casing 4 forms a par- tition wall between the two liquid masses 5 and 6.
- the two liquid mixtures are of different chemical compositions in order for the first liquid mixture to have a lower freezing point than the second one.
- the liquid 5 in the outer casing -3 is assumed to consist of a mixture of spirit and water in such proportions that ' the freezing point of the liquid is at, e.g., -16 °C.
- the liquid contains an alkaline compound, such as bicarbonate, as well as a salt, e.g. phenolphthalein, which becomes coloured in an acid environment, but not in an alkaline one.
- the liquid 6 in the inner casing 4 may consist of a mixture of spirit and water, although in such proportions that the freezing point for this liquid is at least somewhat higher than the freezing point of the liquid 5.
- the freezing point of the liquid 6 may, for instance, be -12 °C.
- a suitable acidify- ing compound is also included, e.g. acetic acid.
- the outer casing 3 is made of a material, e.g. a thin and soft plastic film, which resists low temperatures without becoming brittle or otherwise degradable.
- the material in the inner casing 4 should be of such a type that the material pre- serves a fundamental elasticity or softness at degrees above zero, but becomes brittle and degradable at a certain, lower temperature, e.g. -12 °C.
- the shown colour indicator may be manufactured by filling the two liquid mixtures 5, 6 in long nar- row, thin plastic film casings, which are cut off individually and sealed by means of butt welds 7.
- the indicator has a flat basic shape, and may, on one of the two opposite major faces thereof, be provided with a layer (not shown) of glue or other adhesive for a permanent application of the indicator on a package.
- fig 1 is illustrated how a rectangularly shaped colour indicator 2 may be applied in a countersink in the surface of the package 1.
- fig -2 a countersunk temperature indicator 2 is shown, having a round basic shape.
- fig 3 is illustrated how the colour indicator 2 may be in the form of a label pasted on the outside of the package.
- the temperature indicator After the temperature indicator has been applied to or integrated into the package and the article in question has been packed in the package, refrigeration of the package and its content starts. Conventionally, refrigeration is carried out at very low temperatures in order to hasten the freezing process. Inside the temperature indicator, the following then takes place: As the temperature falls from the room temperature, heat is transported from the liquids 6, 5 via the cas- ings to the cold surrounding. When the temperature in the liquid 6 falls, the volume of the liquid decreases at the same time as the volume of the inner casing 4 decreases, the material in this casing becoming more brittle. When the temperature has fallen to -12 °C, the liquid 6 freezes to ice and begins to expand. Somewhat later also the liquid 5 begins to freeze to ice and to expand.
- the acid liquid 6 may ooze out into the liquid mass 5 and acidify the same, a chemical reaction takes place, during which the salt (e.g. phenolphthalein) in the liquid 5 becomes coloured.
- the salt e.g. phenolphthalein
- the initially transparent state of the liquid is altered to an opaque, coloured state. This change of state is not reversible and will subsist also if the package and the content thereof are frozen down again.
- the temperature indicator should have a certain delay in the function thereof by requiring a certain quantity of thermal energy in order to melt the ice masses 5, 6 before the reaction takes place. This means that the indica- tor does not react immediately at a temperature rise. By the fact that the reaction is delayed, it is guaranteed that an indication of an exceeding of the limit temperature does not arise by virtue of a momentary supply of heat, e.g. by hand contact during manual handling in a shop or the like.
- a particularly preferred embodiment of the invention is illustrated, applied to such packages that in a conventional way include a bar-code 8. In this case, a temperature indicator 2 is applied in such a way that the same at least partly covers the bar-code.
- the temperature indicator constitutes no obstacle for reading the bar-code by means of a conventional, stationary or mobile code reader, e.g. at a shop's cash-point. Therefore, if the temperature indicator 2 assumes the transparent state thereof on the occasion of sale to the final con- sumer, the consumer as well as the shop manager can with certainty observe that the article has not been submitted to re- freezing because the bar-code can be read. However, if the article for one reason or another would have been thawed and again refrigerated, the transparent state of the temperature indicator is converted to the opaque state, which is shown in fig 5'.
- a temperature indicator made in this way by means of temperature sensitive crystals may in practice be used not only for frozen goods but also for cold goods, the desired temperature of which being above 0 °C but considerably below room temperature.
- the crystal mass may also be applied directly to the package by printing or painting. It should also be pointed out that other changes of conditions than between transparency and opacity are feasible, e.g. simple colour changes, volume changes, location changes or combinations thereof.
