Abstract: A method for dealkalizing the inner face (5) of the wall (2) of a glass container (1), which wall (2) delimits a cavity (3) and an opening (4) providing access to the cavity (3), comprising supplying a glass container, the inner face of the wall of which has a temperature of at least 350° C., and introducing into the cavity, with the inner face having a temperature of at least 350° C., a treatment liquid containing a substance designed to react under the heat's effect to bring about dealkalization of the glass, the introducing comprising injecting, by way of an injection head (11) disposed at a distance from the opening in the container and outside the latter, a predetermined metered quantity of the liquid as a spray cone (C) that is sufficiently narrow for all of the metered quantity to pass into the cavity. Also, methods and installations for treating glass containers.
