Title
(EN) TIME INDICATOR HAVING DISCRETE ADHESIVE
(FR) INDICATEUR DE TEMPS COMPRENANT UN ADHESIF DISCONTINU
Abstract
(EN)
A time indicator is provided that changes color or produces an image or information after a specific time interval. The time indicator includes a base substrate (40) with colored dye (38) deposited on a first surface; and a substrate (30) having an adhesive (36) on a first surface (35) thereof, the adhesive positioned at discrete locations on the first surface (35) of the substrate. The substrate and the base substrate are put into adhesive contact. The adhesive contacts and coacts the colored dye to dissolve the dye and permit the dye to migrate through the adhesive to cause a color change visible through the substrate. The discrete adhesive inhibits lateral migration of the dye to preserve the image or information of the dye in a clear and/or understandable condition.
(FR)
Indicateur de temps qui change de couleur ou produit une image ou des informations après un intervalle de temps spécifique. L'indicateur de temps comprend un substrat (40) de base sur une première surface duquel est déposé un colorant (38); et un substrat (30) sur une première surface (35) duquel est situé un adhésif (36), cet adhésif (36) étant positionné à des endroits discontinus sur la première surface (35) du substrat. Le substrat et le substrat de base sont mis en contact adhésif. L'adhésif se trouve en contact avec le colorant et agit avec ce dernier pour dissoudre le colorant et lui permettre de migrer dans l'adhésif pour provoquer un changement de couleur visible à travers le substrat. L'adhésif discontinu empêche le colorant de migrer latéralement pour maintenir l'image ou l'information donnée par le colorant dans un état visible et/ou compréhensible.
