Abstract

Automatic provision for sealing 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 maintain the obturator applied against the seat, in that the closing action is exerted by a sealing means in combination with elastic means for activating the first ones, and of a seating means for said sealing means, so that the sealing means and the elastic means are elements constituents of the same piece, while the seat means form part of the body of the container to be closed, characterized in that the sealing means form part of a body provided with a projection whose central zone is cylindrical and its end areas are conical trunks, deriving from one of these ends a stem that joins the elastic means, of mod or that, for the temporary decoupling position, said projection is introduced into the container, being neutralized by the action of the elastic means, a new closing contact being established within the container between the flank of the frustoconical end of the projection of the sealing means and the corresponding frusto-conical flank of the seating means, the momentary opening of the container being achieved by pressing the outside of the stem, overcoming the action of the elastic means, which then re-establish the temporary closing position.
