Abstract

Automatic shutter for container containers of liquids at atmospheric pressure, of the type comprising a body delimiting a seat, a shutter movable with respect to said body, and an antagonistic elastic element tending to keep the obturator applied against the seat, in which the action closing is exerted by elastic means for activating the first, and a seating means for said sealing means, whose sealing means and elastics are constituent elements of a single piece, while the seating means are part of the the body of the container to be closed consists of two annular projections located at one end of a rod which, at the other end, joins the elastic means, each of whose projections has a frustoconical profile on its two flanks, in correspondence with the profile of the seat means, so that in the durable closing position, the above mentioned annular projections are lan located on one side and on the other side, respectively, of the seating means, forming a double contact, while for the temporary closing position, the inner shoulder is introduced into the container, by pressing the stem and elastic transfer of the affected parts, leaving said projection is neutralized, so that the closure is formed by a simple contact between the outer projection and the corresponding inner seat, the momentary opening of the container taking place by pushing the stem until the outer projection is separated from the inner seat, the previous one being restored closing situation upon cessation of pushing the stem and by the reaction of the lugs of the elastic means resting on the base of the container.
