Abstract
The invention relates to: 1) a process for the mass production of hollow glass articles which, when positioned beside one another with the same orientation in one and the same plane, are liable to come into mutual contact along a surface of revolution, characterized in that after they have left the annealing lehr, they are rotated through one turn at least along the axis of said surface of revolution, this surface then being coated, by a process without any solid contact, with an additional layer which reduces the coefficient of friction; 2) a hollow glass article as obtained by this process; and 3) a packaging assembly of such articles.
