An annular seal for flasks, essentially characterized in that it consists of a very thin, laminar material in the form of a ring, whose upper edge extends towards the inside of the circumference forming a fairly extensive flat rim concentric and perpendicular to the lateral surface of the ring. The ring and the lower edge is also capable of bending inwards when the seal exerts the function to which the plug and bottle coupling is intended, forming another flange parallel to the upper one.
