Abstract

The invention provides a time-temperature cumulating indication label (TTI) which can be stuck to or tied on the goods. The key components of the label comprise at least a color-changing substance. The color-changing substance has entirely different colors under the storage temperature and in the activated state. In the activated (use) state, the color of the label has gradual significant changes which can be seen by the naked eyes along with the changes of time and temperature (the color can change from deep to light, from light to deep and from one to another). Therefore, the label can be conveniently used on such products as medicines, biologicals, food and the like needing to be transported, stored and sold by the cold chain systems. The color of the label exceeds the design range, indicating that the product quality exceeds the control range (exceeds the time limit).

Description

Time-temperature cumulating indication label

Affiliated technical field

Patent of the present invention relates to a kind of time-temperature cumulating indication label and manufacture method thereof, and its is pasted or ties up on the article of cold chain system, determines relatively that by label color and default standard colors the quality of product is whether in controllable scope.

Background technology

The quality of food and other perishable products (as biological products) depends on condition of storage, as storage temperature from producing or packing, up to its last effective holding time that arrives in ultimate consumer's hand.When temperature increased, the speed of biochemical reaction also can increase, so rate of deterioration is accelerated.

In general, all have strict temperature to limit to the storage of food and other perishable products, for example in the time how long, how many degree are its temperature can not surpass.Otherwise its quality can be affected or can not use.

At present, such product only is marked with the date of manufacture term of validity and storing temperature on the packaging.Since will be through one very long period from the production of product to using, and to pass through a plurality of links such as manufacturer, accumulating merchant, dealer and consumer, and therefore, the actual temperature variation that experiences of product is difficult to discovery and record.Whether final consumer will qualified as the quality that can't determine product.

Therefore, developing device that a kind of time of continuous monitoring product and storing temperature change just becomes and is necessary very much.

At present, domestic have only a relevant patent (but normal temperature storing temperature label 200520075871.6).But its complex manufacturing technology is unsuitable for production in enormous quantities.

This patent can solve above deficiency.

This patent relates to a kind of time-temperature cumulating indication label, and this indicating label can changes colour, its color and residing environment, and concentration becomes correlativity with the time.Can distinguish by naked eyes whether product quality conforms to quality requirements.

Description of drawings

Fig. 1 is label synoptic diagram before using, and middle circular colour code is the color before the tag activation, and periphery 1-8 is the standard colour code that prints, and is illustrated respectively under the temperature conditions of regulation change in color situation after the different storage times.For example under 4 ℃ of conditions, 1 is the color after 1 day, and 2 is the color after 5 days, or the like, 8 is the color of (inefficacy) after 30 days.

Fig. 2, for label uses (activation) back synoptic diagram, middle circular colour code is the color of tag activation, it is effective that middle circular colour code changes to 7 expression products from 1.Periphery 1-8 is that the standard colour code that prints remains unchanged.

Fig. 3, for label uses (inactivation) synoptic diagram after some days, the color of middle circular colour code change color to 8 expression product failure, periphery 1-8 is that the standard colour code that prints remains unchanged.

Claims

1. time-temperature cumulating indication label, whether also it is characterized in that: along with the variation of temperature and time, corresponding variation can take place in the color of the active component of label, indicate product quality within the standard of desired design (perhaps in the term of validity) with this.Be applicable to the product of cold chain system accumulating.

2. standard colour code or Standard Colors series colour code that around the time-temperature cumulating indication label according to claim 1, the active component of label or next door has one (individual) or polylith (individual) to print.The color of the active component of label and its just can illustrate that with reference to the colour code comparison product quality is whether within the standard of desired design (perhaps in the term of validity).

3. time-temperature cumulating indication label according to claim 1, its main active substances are a kind of chemical substances of the color of temperature variation in time.Comprise chemical substances such as photo-acid agent and PH indicator (or indicator mixture), light trigger and photochromic polymer, alkynes class.
