摘要： A tamper evident system for indicating when a closed enclosure (24) has been opened comprises a window (21) and a sensor (22) colour sensitive to presence of a gas. The sensor (22) is located in the enclosure (24) so as to be visible through the window (21). Any compositional change of gas in the enclosure (24) is signalled by a change of colour of the sensor (22).

摘要： A gas indicator (11) for a modified atmosphere food package (19) comprises a series of strips (12,13,14,15,16) which progressively change colour as the proportion of carbon dioxide in the atmosphere progressively changes in magnitude due to absorption of the carbon dioxide by the food product (17) over time. The indicator (11) thus is "tuned" to indicate changing atmospheric conditions inside a see-through envelope (10) and thus the condition of the product (17) can be monitored and any tampering with the package (19) is evident.
摘要翻译：用于改性气氛食品包装（19）的气体指示器（11）包括一系列条带（12,13,14,15,16），随着大气中二氧化碳的比例逐渐变化，逐渐变化颜色，由于随着时间的推移，食品（17）吸收二氧化碳。因此，指示器（11）被“调整”以指示透明外壳（10）内的变化的大气条件，因此可以监视产品（17）的状态，并且与包装（19）的任何篡改是显而易见的。

摘要： A temperature sensitive fluid indicator (10) comprises an envelope (11) formed of two layers of transparent polymeric film material which are welded one to another in a matrix of welds (12) to provide an array of cells (13) each containing a temperature sensitive fluid. The fluid may be an emulsion and indicia in the form of a colour, or a word such as "VOID", or a pattern may be reverse printed on an inner surface of one of the layers so as to be visible through the cells (13) and through the other of the layers when the emulsion changes to a matrix phase.
摘要翻译：温度敏感流体指示器（10）包括由两层透明聚合物薄膜材料形成的外壳（11），所述两层透明聚合物薄膜材料在焊缝（12）的基体中彼此焊接，以提供每个包含温度敏感液体流体可以是乳液，并且以颜色或诸如“VOID”这样的词形式的标记，或者图案可以反向印刷在一个层的内表面上，以便通过细胞（13）可见）并且当乳液改变为基质相时通过另一层。

摘要： A multi-wall film (10) comprises two layers (11,12) of barrier film material which are peripherally sealed (13) one to another to form an enclosure (14), the enclosure (14) including a material (15) which is colour sensitive to presence or absence of a gas. A flexible container formed of such a film (10) is tamper evident because, if the film (10) is severed, the gas to which the material (15) is sensitive escapes from or enters in the enclosure (14) and the material (15) thereby changes colour and the colour change is visible. The enclosure (14) may be provided with spacing means, such as a mesh (16), the presence of which increases diffusion rate of gas into and out of the enclosure (14) when the film (10) is severed.
