The device for marking a surface of a hollow glass article (1), comprises a plunger (15) comprising a raised or hollow pattern and a support assembly (20), and a radial movement device. The hollow glass article defines a container that has an opening, a bottom opposite to the opening and a side wall delimited by an outer surface and an inner surface. The support assembly: is movable between a first position in which the plunger is placed outside of the article and a second position in which the plunger is placed inside the article; and comprises a stationary bearing portion (26). The device for marking a surface of a hollow glass article (1), comprises a plunger (15) comprising a raised or hollow pattern and a support assembly (20), and a radial movement device. The hollow glass article defines a container that has an opening, a bottom opposite to the opening and a side wall delimited by an outer surface and an inner surface. The support assembly: is movable between a first position in which the plunger is placed outside of the article and a second position in which the plunger is placed inside the article; and comprises a stationary bearing portion (26) at the opening of the article, and a moving portion (35) that is moved in an axis of the article and supports the radial movement device. The radial movement device is arranged in the second position of the support assembly. The plunger is moved between a passive position spaced away from the inner surface of the side wall and an active position pressed against the inner surface to imprint the raised or hollow pattern. The plunger further comprises an L-shaped element comprising: a vertical branch supporting a removable plate provided with the pattern; and a horizontal branch positioned in a guideway formed in the stationary bearing portion and connected to the radial movement device. The moving portion of the support assembly comprises a base extending parallel to the stationary bearing portion and supporting a sliding column (40) in a well formed in the stationary bearing portion, and is connected to a member for controlling the movement of the moving portion formed by a hydraulic or pneumatic cylinder. The radial movement device comprises an inclined ramp (43) that is formed in the sliding column and cooperates with a pin secured to the horizontal branch of the L-shaped element. The ramp is inclined towards the center of the bottom of the article. A return member is inserted between the stationary and moving portions to return the plunger to the passive position. Independent claims are included for: (1) a process for marking a surface of a hollow glass article; and (2) a hollow glass article. |
