Abstract

A dropper cap, characterized by the fact of being composed of three coupled pieces; a piece tightly fixed to the bottle or container in which it is applied, constituted in such a way that internally it has a through passage and externally a peripheral upper recess, which establishes a neck with external ribs that delimits the mouth of said conduit, and a grooved concavity that from the upper edge of said neck extends downward and widens in its lower position; another piece, tightly fixed to pressure tightness in the neck of the previous piece forming a closure, constituted so that internally it has a hollow part and laterally has a portion with a spherical concavity provided in its bottom with an orifice communicating with said part hollow, which concavity by its lower front part is prolonged forming a groove, by conformation of the wall in mediacaºa, conjugable, by adjustment with the area of the neck, with the groove of the first piece, at the same time as said inner hollow part it remains as continuity of the conduit of this first piece; and a nozzle whose spherical upper end and provided with an external protuberance is tightly mounted under pressure in said spherical concavity of the second part, so that from a position in which its conduit is axial to the orifice of such spherical concavity it can be displaced and folding down by taking shelter in the grooved concavity of the previous pieces while the protuberance passes to close said hole when fitting in it to seal.
