Patent

CA 2428681

The inventive closure is comprised of the annular part (11), to which a lid (17) is joined by means of a hinge (19), and of the spout (25) that is pushed inside the annular part (11). When pushing the spout (25) into the annular part, the edge of the spout (29) abuts against segments (47) and is thus brought into the optimal drop-preventing shape. When closing the lid (17), the air in the slot can escape through the outlets (45) so that it does not impede the closing or have the tendency to open the closure. Also during closing, the upper end (28) of the spout (25) comes into contact with the supporting surfaces (50), which are arranged in an interspaced manner inside the slot (23), whereby remaining liquid can be accommodated in the cavities (49).

L'invention concerne un système de fermeture comprenant une partie annulaire (11) sur laquelle est articulé un couvercle (17) au moyen d'une charnière (19) et une partie de déversement (25) introduite dans la partie annulaire (1). Au moment où la partie de déversement (25) est introduite, l'arête de ladite partie de déversement (29) vient buter contre les segments (27) et adopte ainsi la forme optimale pour empêcher les phénomènes de dégouttage. Au moment où le couvercle (17) est fermé, l'air situé dans la rainure peut se dégager par les sorties (45), de sorte à ne pas entraver la fermeture ou de sorte à ne pas avoir tendance à ouvrir le système de fermeture. Au moment de la fermeture, l'extrémité supérieure (28) de la partie de déversement (25) vient au contact des surfaces d'appui (50) situées à distance mutuelle dans la rainure (23), le liquide résiduel trouvant à se loger dans les cavités (49).
