Flaconnage - Rice grains: specifications and control methods

Scope of application

The "rice grains" are embossed features placed under the thread of a screw finish. They limit the risk of self-unscrewing of the pump, while allowing the consumer to open the bottle to refill it. This document describes in which case these features are useful, and it specifies its geometry.

Document under responsibility of working group:

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.
