Abstract
For the closure of bottles and similar containers for liquid substances, it is foreseen an improved dispensing closure with valve means and safety means constituted of an axially gravity actuated sliding plugger working into a sleeve mounted on the bottle neck, the plugger having a downward opening to fit the stem of an ogive head shaped safety clogging means, whose seat is obtained from the converging walls of an inner section of said sleeve, projecting into the bottle mouth, the whole valve assembly being protected by a pressure cap fitting over the said sleeve.

A closure for containers, particularly bottles, comprising a closure member mounted on a container and having a passage adapted for alignment with an opening of the container, said closure member forming an outer and an inner valve seat;
- cap means surrounding said closure member and having a turnable portion which is removable from said container;
- a plug member freely movable under the influence of gravity in said passage between a first storage position and a second dispensing position, said plug member having an outer valve portion and an inner valve portion respectively engaging said outer and inner valve seats when said plug member is in said first storage position, said outer valve portion having an end facing said turnable portion of said cap means and a polygonal recess at its opposite end, said inner valve portion having a mating stem portion received in said polygonal recess;
- and cooperating engaging portions on said turnable portion of said cap means and said outer valve portion so that, when said turnable portion is removed from said container, said inner and outer valve portions move relative to their seats so as to break any adherence between said valve portions and their cooperating valve seats.
