A closure assembly for a container including an internal cap and an external cap which are handled as one cluster is disclosed. The internal cap is tightly fitted into an outlet opening of a container and having a flange formed on an insertion portion, and the external cap has a threaded portion engaged to an outer periphery of the outlet opening to enclose the internal cap, in which the internal cap and the external cap have a corresponding locking member to prevent the internal cap from being disengaged from the external cap. The external cap includes a second engagement portion having a diameter smaller than that of the threaded portion to form a stepped portion and having at least one locking portion formed on an inner periphery of the second engagement portion, and the internal cap includes a first engagement portion protruding upwardly from the internal cap and having a locking portion formed on an outer periphery of the first engagement portion corresponding to the second engagement portion of the external cap.
L'invention concerne un ensemble de fermeture pour récipient comprenant un couvercle interne et un couvercle externe formant un bloc. Le couvercle interne s'insère étroitement dans l'orifice de sortie d'un récipient et présente un rebord sur sa partie d'insertion cependant que le couvercle externe présente une partie taraudée se vissant sur la périphérie externe de l'ouverture du récipient et recouvrant le couvercle interne. Les deux couvercles comportent chacun un élément de blocage qui les empêchent de se désolidariser l'un de l'autre. Le couvercle externe comporte une seconde partie d'engagement d'un diamètre plus faible que celui de la partie taraudée, qui forme un décrochement et comporte au moins une partie de blocage sur sa périphérie. Le couvercle interne comprend une première partie d'engagement tournée vers le haut et présentant une partie de blocage formée à la périphérie de la première partie d'engagement correspondant à la seconde partie d'engagement du couvercle externe.
