Abstract
Dental adhesive container dropping system, characterized by the combination of (a) a dental adhesive polymerizable with visible light dissolved in acetone or acetic acid ethyl ester; (b) a light impermeable bottle (1) for the dental-adhesive, elastically deformable for the drop formation, with a laminated wall (3) comprising (b1) at least one polymer layer (15) impermeable to acetone or acetic acid ethyl ester, and (b2) at least one light impermeable, elastically deformable polymer layer (13); (b3) a compatibilizer guaranteeing the laminate structure and which can be formed as at least one intermediate layer (17) or which can be admixed to the elastically deformable polymer layer (13); (c) a light impermeable and evaporation-proofsealable dropper insert (20) of light impermeable plastic material with a dropper conduit (50) enlarging from the inner to the outer part, whereby; (c1) the diameter at the inlet end corresponds to the desired drop size; and, (c2) the diameter at the discharge end is within the range of from 0.1 to 0.25 MM.
