Abstract: The present inventing relates to a method for marking at least one inner face of a container with at least one given pattern, in which method the inside of said inner face is at least partially coated with a pigmented sol-gel layer that reacts to laser radiation, by spraying or by means of a stamp applied to a precise zone of the layer provided for containing the pattern, and the pattern is developed by interaction between the sol-gel and UV laser radiation specifically programmed according to the pattern to be revealed, the UV laser radiation being emitted by a device comprising an optical system having a long optical length that allows a field depth of more than 1 mm to be obtained. The present invention also relates to a device suitable for implementing this method and to a container obtained by this method.

Abstract: A method for coating at least one portion of the inner surface of a container with a curable liquid material, a device for implementing said method; and a container obtained by said method. The container is positioned on a holder and secured thereto; a tool for applying the coating is inserted into the container and the coating liquid is applied using the tool on the inner surface of the container. The container is tilted at a first angle determined in relation to the vertical and rotated relative to the tool at a first predetermined speed V, while heating said container to a predetermined temperature. The liquid coating material is uniformly applied to the inner surface of the container to obtain a uniform, substantially identical thickness.

Abstract: A sheet stacking apparatus for storing a plurality of sheets is disclosed having a storage chamber having a first transverse dimension, a platform located within the storage chamber for storing a plurality of sheets in a substantially vertical stack thereon, a feeder for feeding a top sheet from the stack, and means for moving the platform upwards to hold the stack in operative contact with the feeder, wherein the platform comprises a support portion having a second transverse dimension which is less than the first transverse dimension, for allowing sheets stacked on the platform to droop below the support portion in at least one overhanging region.
