Thermochromic ink safety label for chafing fuel cans and methods of making the same

   
   

A safety label for use with chafing fuel cans capable of providing the user with information about the current physical characteristics of the can, including as they relate to temperature, employing the use of thermochromic materials dispersed within a media such as ink or paint. The thermochromic materials are capable of undergoing a sharp, reversible visible metachromism between the temperatures of -40.degree. C. and 80.degree. C. The method of manufacturing safety labels according to the invention include the steps of applying informational indicia on the safety label, and then covering such indicia with the media containing the thermochromic materials dispersed therein. When the chafing fuel can is ignited, the media with the thermochromic materials visually undergoes a metachromism, rendering the media invisible, thereby revealing the informational indicia applied with the non-thermochromic ink. After the chafing fuel can has been extinguished the temperature decreases, whereupon the media with the thermochromic material reappears, thereby, covering up again the informational indicia.

Uma etiqueta de segurança para o uso com as latas aquecendo por atrito do combustível capazes de fornecer o usuário com a informação sobre as características físicas atuais da lata, incluindo como se relacionam à temperatura, empregando o uso dos materiais thermochromic dispersados dentro do meios tais como a tinta ou a pintura. Os materiais thermochromic são capazes de submeter-se a um metachromism visível afiado, reversível entre as temperaturas de -40.degree. C. e 80.degree. C. O método de manufaturar etiquetas de segurança de acordo com a invenção inclui as etapas de aplicar o indicia informativo na etiqueta de segurança, e então de cobrir tal indicia com os meios que contêm os materiais thermochromic dispersados nisso. Quando a lata aquecendo por atrito do combustível é inflamada, os meios com os materiais thermochromic submetem-se visualmente a um metachromism, rendendo os meios invisíveis, desse modo revelando o indicia informativo aplicado com a tinta non-thermochromic. Depois que a lata aquecendo por atrito do combustível estêve extinguida as diminuições da temperatura, whereupon os meios com o material thermochromic reaparecem, desse modo, cobrindo acima outra vez do indicia informativo.
