Recommendation for flaconnage crimping
Scope of application
This guide describes the five essential rules to be observed to properly crimp a pump with an aluminium ferrule on an FEA type glass finish used for perfumery, according to the EN 14854 - AEROSOL CONTAINERS – GLASS CONTAINERS – DIMENSIONS OF THE NECK FINISH standard and the Cetie document GME 40.05 - DIMENSIONS OF THE NECK FINISH FOR GLASS AEROSOL CONTAINERS. These rules should be applied to meet the current market requirements. This guide explains the crimping process using a crimping tool. It does not describe crimping with rotating heads (rolling).

Flaconnage geometry
WG chair: Lorenzo PASQUALI - BORMIOLI LUIGI S.p.A.
This joint group aims to produce dedicated documentation on glass flacons for the cosmetics, perfume, and pharmacy sectors:
- Cetie 'GME'* neck finishes data sheets concerning glass crimping neck finishes (FEA), screw neck finishes, neck finishes for pumps and snap-on neck finishes, etc.
- All data sheets of the DT15 series, identifying tolerances and standard test methods applicable to molded glass flacons;
- Data sheets concerning critical visual defects of flacons, neck finishes nomenclature, etc.
- Guide of crimping recommendations.
*Initiated by the glass industry in the 1960s, the acronym 'GME' stands for 'Glass Manufacturing Experimental'. The idea was that Cetie, as an unofficial standards body, would only publish 'experimental' data sheets, before submitting these to the official standards bodies. At the same time, in the USA, the acronym 'GME' was also used. As the original meaning was lost over time, this nomenclature for Cetie's glass finishes documents has been, later on, applied to the PET finish data sheets.
