Abstract
本实用新型公开了一种低温流通物品货架寿命指示装置，包括：扩散管、装有低温熔点的物质扩散剂的容器；扩散管的下端与装有低温熔点的物质扩散剂的容器用塑料隔膜间隔，熔融封合连成一体。该指示装置通过在特定的温度条件下化学物质超过其熔点而溶解，在气压的和渗透压的作用下，这种染色的化学物质会沿着毛细管或多孔性扩散管移动，其移动的距离与高温的时间成比例。从是否移动或移动的距离可以判断出低温流通食品在流通和消费过程中是否经受过高温或经受高温的时间，从而判断此食品的品质。
Description
所属技术领域
本实用新型涉及一种低温流通物品货架寿命指示装置。
背景技术
在物质生活丰富和人民生活水产提高后，许多食品、药品和电子产品原料为了保证其质量均在低温下进行流通，有的在冰点以上的温度下冷藏，有的在冰点以下的温度下冷冻。已知这些低温流通物品的质量、安全性和货架寿命取决于温度，而不取决于时间。但因为在销售、贮藏及零售时其状态为冷冻，这些低温流动的物品很难判断其安全性和货架寿命，特别是冷冻状态下流通的物品，作为消费者无法判断其质量的好坏和是否安全，即无法知道其在流通的过程中是否经受过解冻或经受过高温的处理。
发明内容
本实用新型的目的是提供一种扩散型低温流通物品货架寿命指示装置，通过一种能移动的化学物质，装在装置内，达到在解冻时化学发质即发生移动，从而能指示出低温物品在低温流通中经受过高温的指示装置。
为达到上述目的，本实用新型采用的技术方案是包括：扩散管、装有低温熔点的物质扩散剂的容器；扩散管的下端与装有低温熔点的物质扩散剂的容器用塑料隔膜间隔，熔融封合连成一体。
所说的扩散管为灯芯草、海绵、多孔纤维、棉花、各种毛细管等。
所说的装有低温熔点的物质扩散剂的容器的材料为塑料、纸质材料、玻璃和金属材料等。
所说的装有低温熔点的物质扩散剂为脂肪酸脂，是熔点12℃的硬脂酸丁酯、-1.1℃的邻苯二甲酸二甲酯、-10℃的邻苯二甲酸二丁酯、-17℃的辛二醇等。
本实用新型具有的有益的效果是：
装有低温熔点的物质扩散剂的容器中的化学试剂的熔点不同，可以在不同的温度下呈现固体和液体之间的转变，当试剂呈液体状态时在毛细管力的作用下可以沿着扩散管的方向移动。移动的距离与呈液体的时间基本成比例，从而可以断定本装置是否经受高温和经受高温的时间。扩散管的作用是使试剂能沿着一定的方向移动，从而达到判断经受高温的时间的目的。间隔塑料的作用在于平时未使用时防止产品即已扩散，保证产品在使用以前的质量，使用时将间隔用力压破，从而在贮存器和扩散管之间形成一个通道，使试剂能从贮存器向扩散管方向移动。本实用新型非常实用、使用方便，可以作为一切低温流通物品的保持低温的指示装置。
附图说明
下面结合附图和实施例对本实用新型作进一步说明。
附图为本实用新型的结构原理示意图。
具体实施方式
如附图所示，本实用新型包括：扩散管1、装有低温熔点的物质扩散剂的容器3；扩散管1的下端与装有低温熔点的物质扩散剂的容器3用塑料隔膜2间隔，熔融封合连成一体。
所说的扩散管1为灯芯草、海绵、多孔纤维、棉花、各种毛细管。
所说的装有低温熔点的物质扩散剂的容器3的材料为塑料、纸质材料、玻璃和金属材料。
所说的装有低温熔点的物质扩散剂为脂肪酸脂，是熔点12℃的硬脂酸丁酯、-1.1℃的邻苯二甲酸二甲酯、-10℃的邻苯二甲酸二丁酯、-17℃的辛二醇。
将本装置粘贴在低温流通物品的包装上，当物品在低温贮藏和流通过程中，装有低温熔点的物质扩散剂的容器通过在特定的温度条件下化学物质超过其熔点而溶解，在气压的和渗透压的作用下，这种掺有染色剂的化学物质会沿着毛细管或多孔性扩散管移动，其移动的距离与高温的时间成比例。从是否移动或移动的距离可以判断出低温流通食品在流通和消费过程中是否经受过高温或经受高温的时间，从而判断此食品的品质。
所说的染色剂可以是所有的食品用色素，主要包括：苋菜红、苋菜红铝色淀、亮蓝、亮蓝铝色淀、酸性红、β-胡萝卜素、赤藓红、赤藓红铝色淀、诱惑红、诱惑红铝色淀、靛蓝、靛蓝铝色淀、新红、新红铝色淀、胭脂红、胭脂红铝色淀、叶绿素铜钠盐、日落黄、日落黄铝色淀、柠檬黄、柠檬黄铝色淀、二氧化钛、橡壳棕、胭脂树橙、落葵红、甜菜红、黑豆红、黑加仑红、密蒙黄、焦糖、胭脂虫红、红花黄、可可壳色、菊花黄浸膏、玉米黄、越橘红、姜黄素、栀子蓝、葡萄皮红、紫草红、沙棘黄、酸枣色、紫胶红、红曲红、桑椹红、天然苋菜红、天然β-胡萝卜素、NP红、柑橘黄、辣椒红、辣椒橙、花生衣红、萝卜红、红曲米、金樱子棕、玫瑰茄红、高梁红、藻蓝、茶绿色素、茶黄色素、植物炭黑等。
