Abstract (en)
[origin: US2005173371A1] A composite stopper ( 1 ) made of synthetic materials, particularly for bottles and similar containers, comprises a substantially cylindrical central body ( 2 ) made of thermoplastic material and defining a longitudinal axis (L), with a side surface ( 3 ) and two substantially flat end faces ( 4, 4' ), and at least two elastic rings ( 5, 6 ) located in corresponding annular seats ( 7, 7' ) on the side surface ( 3 ). The two elastic rings ( 5, 6 ) are made of plastic materials which are different from each other and from the base material of the central body ( 2 ). The base materials of the elastic rings ( 5, 6 ) are non-toxic, in particular at least one of them being made of nitrile rubber having a formulation able to ensure optimum gas impermeability, and at least the other one being made of silicone rubber having a formulation able to ensure complete compatibility for alimentary use and a high resistance to ageing.
