Luminescent beverage caps and method for manufacturing and applying it

Description

This invention relates to luminescent beverage caps (1) suitable to seal bottles of very diverse beverages and other liquid materials. These caps emit 'cold light' at external illumination and in given cases after external illumination, too. The material of caps is some kind of plastic into which a luminescent material is mixed. This cap can be worked out by the help of whatever technologies usual in the plastic manufacturing, first of all by injection moulding. This cap can constitute the full sealing of the bottles, but there is an another solution, too, in which the cap is put onto another cork. This invention relates to a method, too, according to which there is an opportunity to differentiate bottles containing beverages of various type by the help of the arising luminescence in dusk and darkness, too, and these caps can be also employed to form decorations in semi-dark rooms.
