Problems solved by technology

In particular, the indicator cannot be activated at times other than the time of manufacture and must be installed on the occasion of storage of the goods to be tested
Furthermore, while the embodiment described in this patent application, using an osmotic couple as elements to apply a constant pressure to a viscous fluid, has many advantages, it is still very complex from a manufacturing point of view

Embodiment Construction

[0028] Figure 1 shows a first embodiment of the indicator device according to the invention; reference number 1 shows the base layer of the multi-layer structure. The base layer 1 is provided with a surrounding groove 101, which communicates with the outside through an opening 111 at one end, and the other end 121 is connected with a through hole 112; the through hole is drilled at the bottom of the chamber 102 formed in the second layer 2 in the wall. On this layer there is a permeable semi-permeable membrane 3 which separates said chamber 102 from a chamber 104 formed on the bottom of layer 4; said chamber communicates with another chamber 204 through a large side channel 114, so that A further chamber as described is formed on the top surface of said layer 4 . Chamber 104 and chamber 204 are separated from each other by a movable pin 604 ; this movable pin 604 is inserted in slot 134 communicating with opening 114 . Chamber 104 also communicates through opening 124 with c...

Abstract

Residual lifetime indicator device for perishable consumer products, comprising a material having a property which can change as temperature changes according to a given function, actuating means (102, 104, 204; 10) which act on said material to make it show the aforesaid property, and indicating means (105; 308) coupled to the material / actuating means combination, said indicating means indicating the residual lifetime in relation to the expiry date of the product, said material being a fluid with a viscosity which can change depending on temperature, which fluid flows into a pipe having a given section, characterized in that the actuating means comprise an element to apply a pressure differential to said fluid (102, 104, 204; 10), the flow of said fluid being connected to said indicating means (105; 308), activating means (604; 14) to activate said element being provided to apply a pressure differential to said fluid (102, 104, 204; 10).

Description

technical field [0001] The present invention relates to a system for assessing the effect of temperature changes on perishable products, and more particularly to a remaining shelf-life indicator device suitable for consumer products, especially food. Background technique [0002] Most industrial products, especially those in the food, agricultural or pharmaceutical industries, have some characteristic that deteriorates until it disappears within a given period of time, usually indicated as the product's expiry date or expiry date. It should be noted, however, that this time refers to a product that has been optimally stored and undamaged, as stated in the note given on the packaging of said product; The best way to get stored. [0003] According to document US-A-5531180, there is known a device capable of recording the temperature changes experienced by products, especially deep-frozen products, and indicating the range of temperature changes by means of suitable means. Ho...
