Abstract

Dropper cap characterized by the fact that the dropper cap is constituted by two parts, one of them formed by a sliding cap above and below on the outside of the neck of the container by means of a helical thread made on the inside of its walls truncated cone coinciding with the external thread of the neck having in the lower upper base of the cap a vertical spout with axial hole also frustoconical inside that in the internal part of said base there is a descending annular partition and existing in the lower edge of the base larger open from the same cap an internal annular rim in which it engages in the position of maximum opening such cap an outgoing annular rim made in the neck of the container and separated from the shelf that forms the unión of the neck with the body of the container which separation is which delimits the route gives the cap in the positions of maximum opening and closed tight this is unscrewed and threaded, the inside of the neck of the container having the second part of the stopper formed by a cylindrical body having two sections of different diameter, one housed inside the neck which is smaller in diameter while the other appears disposed in the outside of the rim of the neck and therefore of greater diameter forming this salient part as a bowl that from the center of the bottom emerges a frustoconical prominence with openings that from the greater base reach the minor base from which a block of greater protrudes diameter with a central vertical needle which is housed inside the axial hole of frustoconical walls of the spout of the sliding cap which in its closed position and therefore lowered its frustoconical orifice is sealed by the needle of the cap while in its position of open and consequently raised the needle although it is partially entered inside the spout due to the conicity of its external walls it is not fitted with the inner walls of the cap spout and therefore the liquid contained in the container passes through the hole of the cylindrical body of the cap reaches the bowl through the opening of the frustoconical prominence passes between the then existing separation between the needle and the walls of the cap spout when the container is rotated.
