Abstract:
A method of treating an elastomer packaging element ( 10 ), in particular a stopper for medical or pharmaceutical use, the packaging element ( 10 ) having a bottom portion ( 11 ) that is to penetrate into a neck ( 21 ) of a container ( 20 ) and a top portion ( 12 ) that is to co-operate in sealed manner with a top surface ( 22 ) of said neck ( 21 ) of the container ( 20 ). The top surface of the top portion ( 12 ) is treated by a plasma-assisted polymerization method at atmospheric pressure using a plasma flame created at atmospheric pressure and into which a monomer is injected, the monomer polymerizing on the top surface in order to form a coating ( 18 ).

Claim (Index 1):
A method of treating an elastomer packaging element, said packaging element having a bottom portion that is to penetrate into a neck of a container and a top portion that is to co-operate in sealed manner with a top surface of said neck of the container, the top surface of said top portion being treated by a plasma-assisted polymerization method at atmospheric pressure using a plasma flame created at atmospheric pressure and into which a monomer is injected, said monomer polymerizing on said top surface in order to form a coating, said method comprising a stage of atmospheric plasma-assisted surface activation and a stage of atmospheric plasma-assisted deposition, the method being characterized in that said atmospheric plasma-assisted surface activation stage comprises passing said plasma flame over said top surface, with the following parameters:\n gas used for generating the plasma flame: air, argon, nitrogen, helium, oxygen, etc.; advantageously air or nitrogen; preferably nitrogen; speed at which the plasma flame passes over said top surface: 10 mm/s to 1000 mm/s, and advantageously 100 mm/s to 500 mm/s, preferably being about 300 mm/s; number of passes over said top surface to perform activation: one cycle to five cycles, advantageously a single cycle; activation gas flow rate: 5 L/min to 200 L/min, and advantageously 10 L/min to 100 L/min, preferably being about 60 L/min; and distance between the nozzle where the plasma is generated and said top surface: in the range 1 mm to 50 mm, and advantageously in the range 5 mm to 35 mm, preferably being about 20 mm.
