Method and device for coating the inner surface of a container and container obtained with such a method

A device for coating at least a portion of the internal surface of a container elongated around an axis Oz with a curable liquid coating material comprising a support for receiving the container which is integral with the container and a tool for application of said coating liquid to at least a portion of the internal surface of the container and means for feeding the liquid material at a predetermined flow rate D, the device comprising means for rotating the container and/or the tool around the axis Oz at a predetermined speed V, means for heating the container to a predetermined temperature and means for insertion of the tool into the container, wherein,

• the container is arranged for and suitable for containing products biocompatible with man and/or animals,
• the support is arranged in order to incline the container by a predetermined first angle α,
• the tool is a spray nozzle,
• and comprising calculation means arranged for controlling and regulating the speed V of the rotating means, the flow rate D for feeding the liquid and the predetermined temperature, as a function of the angle α of inclination of the support, of the parameters of viscosity η of the liquid at said predetermined temperature, of the roughness R of the part of the surface of the container and of the geometric typology of the container, so as to evenly deposit a layer with an identical or substantially identical thickness of liquid coating material over the internal surface of the container, so as to obtain a deposition.
