A dental adhesive delivery system (10) provides a capsule (11) containing a single usage amount of dental adhesive (15) in a non-resealable container (14) for use in treating a single patient. The packaged amount of adhesive (15) may include up to the amount required to treat all of the teeth needing treatment of not more than a single patient, for example in the range of approximately 0.005 to 1.0 ml. The single use container (14) is preferably formed of injected molded plastic cup (20) and includes a reservoir section (30) having a cavity (22) therein that contains the adhesive (15) and a break off section (31) that surrounds an opening (24) that receives a snap fit cap (21). The cap (21) and break off section are discarded and the adhesive (15) is removed with the tip (55) of a wand (12) for application to the teeth of a patient, whereupon the container, which is not resealable, is discarded. A vapor seal secondary containment such as a pouch (13) of foil, plastic or polyfoil material, for example, limits the escape and prevents unacceptable loss of organic carrier or solvent from the adhesive.

Un système de débit d'adhésif dentaire (10) comporte une capsule (11) contenant une dose unique d'adhésif dentaire (15) contenue dans un récipient non refermable (14) permettant de traiter un seul patient. La dose emballée d'adhésif (15) peut renfermer au maximum la quantité d'adhésif requise pour le traitement de la totalité des dents à traiter d'un seul patient au maximum, par exemple, une quantité comprise entre environ 0,005 et 1,0 ml. Le récipient unidose (14) est de préférence fait d'une coupelle (20) en plastique moulé par injection. Il comporte une partie réservoir (30) dont la cavité (22) contient l'adhésif (15) et une partie détachable (31) entourant un orifice (24) recevant un couvercle enclipsable (21). On jette le couvercle (21) et la partie détachable, puis on fait sortir l'adhésif (15) avec l'extrémité (55) d'une tige (12) servant pour l'application sur la dent du patient, à la suite de quoi, on jette le récipient qui n'est pas refermable. Un confinement secondaire étanche aux vapeurs tel qu'un sachet (13) en matériau en feuille, en matière plastique ou en plusieurs feuilles, permet notamment de limiter la perte accidentelle et empêche la perte inacceptable de milieu organique ou de solvant de l'adhésif.
