ABSTRACT:
An ampoule is filled completely. The ampoule, formed from a casing which may be made of plastic, for example, or made of transparent, opaque or coloured glass, is closed after is has been filled by a frustoconical transverse closure device. The casing of the closure device has a wall provided with an expansion compensator, if the elastic properties of the material used to make this latter are inadequate for complete filling. Filling orifices are provided with a conical raised portion on the outside. Disposed inside the container are hollow spheres which permit the effects of liquid expansion to be compensated for, if necessary, and which are used to make the liquid homogeneous. Caps protect the filling orifices.
