<p>The particularity of the system in question is that it permits application of messages indicating the validity date on packages of perishable goods, taking them from pre-printed self-adhesive label forms that carry the message both in letters for the blind, for example in Braille or the like, with the corresponding message in alphanumerical lettering, preferably so that each message is formed both with a predetermined text and a modular text made by combining standard prefixes and additional suffixes. The system basically exploits self-adhesive labels (1) carrying messages regarding expiration dates given both in alphanumerical lettering (2) and in lettering like that of Braille (3) so that each letter of the alphanumerical message corresponds to letters in the Braille message. <IMAGE></p> |
