To obtain the expected performances from the product, technopolymers were selected and used with these objectives:
Results determined a series of characteristics which can be obtained only through the combination of three components, each with its precise task:
The chassis is the core, the structural component of ArdeaSeal closure. Its task is to mechanically control the whole system, avoiding lengthening and keeping constant and uniform in time the interference with the neck of the bottle. It is a stiff support and containment element realized in high rigidity technopolymer through injection molding process. It is protected by international patents.
Thanks to its design it facilitates the insertion of the cork-screw, which is guided, preventing any risks of accidental breaking of the bottle neck.
The only component that comes in contact with the wine, designed ad hoc to allow the use of the best available technopolymer in terms of absence of chemical interactions.
This component is produced with no additives through injection molding process.
Realized during the final manufacturing phase, the body is the soft part which, thanks to the interference with the internal surface of the bottle neck, will guarantee with regularity and uniformity the sealing properties of the closure.
The material used is a thermoplastic elastomer and the process technology is injection overmolding assisted by foaming realized through specific agents.
The research and development phase requested the use of a proper technology developed by M.I.T. in Boston, which employs gas in its supercritical phase to foam the technopolymer. The part of the body inside the structure is the support for the cork-screw.
The employed raw materials undergo specific checks to guarantee the respect of the specifics and maximum performance.
Being products which will be in contact with food, the existing regulations (European legislation - F.D.A.) were used only as reference since stricter internal protocols were applied.
