  • Patent number: 11912611
    Abstract: The invention relates to a method, and to an associated apparatus, for treating a container (1) comprising a glass wall (2) defining a receiving cavity (3) for receiving a product, said glass wall (2) having an inner face (4) and an opposite outer face (5), said glass wall (2) being provided with a first coating that includes a solid residual compound resulting from a step of dealkalization of the glass in the vicinity of the surface of said inner face (4) of said glass wall (2) to which said container (1) had previously been subjected, said method comprising a step of spraying the surface of said glass wall (2) with droplets of a liquid, in order to form on said glass wall (2), starting from said first coating, a second coating which includes said residual compound and which is more transparent and/or more uniform than said first coating.—Treatment of glass-walled containers.

  • Publication number: 20230081839
    Abstract: The invention relates to a method for treating the wall of a glass container (1), which wall delimits a cavity (4) and an opening providing access to said cavity (4), the method comprising: the dispensing of a treatment substance into the cavity, using a dispensing means (12) of which a dispensing orifice (13) is positioned some distance from the opening of the container (1) and outside the latter, the container (1) being in motion relative to the dispensing means (12), and the capturing, by an image-capturing device (16), during the dispensing, of at least one image of a spatial region including the opening of the container (1) and determining, by analysing said image, whether or not a predetermined quantity of substance was introduced into the cavity (4) of the container (1). Method and installation for treating glass containers.

  • Publication number: 20220267203
    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.
