CA 2645754

A drop dispenser has a substantially conical sleeve member with a narrow upper end and a wide lower end. Centrally located at the apex of the upper end of the sleeve member is an aperture which has an inner diameter and is circumscribed by a raised ridge. The aperture and the ridge form a nozzle. The interior space of the substantially conical sleeve member forms a substantially conical chamber between the narrow upper end and wide lower end of the sleeve member. The nozzle is in liquid communication with the chamber through the aperture. The drop dispenser may have external threads at the lower end of the sleeve member for engaging a cap having a protuberance centrally located at its internal top end for hermetically engaging the aperture of the nozzle when the cap fully engages the sleeve member.

Selon l'invention, un distributeur de gouttes présente un élément manchon sensiblement conique pourvu d'une extrémité supérieure étroite et d'une extrémité inférieure large. Une ouverture à diamètre interne et circonscrit par une arête surélevée se situe centralement sur l'apex de l'extrémité supérieure dudit élément manchon. L'ouverture et l'arête forment une buse. L'espace interne dudit manchon forme une chambre sensiblement conique entre l'extrémité supérieure étroite et l'extrémité inférieure large dudit élément manchon. La buse permet d'acheminer du liquide à travers l'ouverture, à partir de la chambre. Ce distributeur de gouttes peut comporter des filets externes au niveau de l'extrémité inférieure dudit élément manchon pour permettre l'entrée en prise d'un couvercle qui comporte une protubérance située centralement au niveau de son extrémité supérieure interne de manière à entrer en contact hermétique avec l'ouverture de la buse, lorsque le couvercle entre complètement en prise avec l'élément manchon.
