<p>Bottle neck has a simple stopper and is transformed by application of a cladding into one which can receive a resealing stopper which can be fixed by screwing, as in FR. 1476799. The cladding has, beyond the screw-thread towards the bottle body, a regular surface to which a sealing collar of the stopper can be applied. Pref. the cladding is directly moulded around the neck, e.g. in epoxy resin; or it may be a metal sleeve fixed with epoxy resin; or it may be a metal sleeve fixed with epoxy resin onto the neck.</p> |
