Abstract
A closure device includes a stopper assembly that provides swing-top closure of a vessel, plus an adaptor so the device can be used with screw-top vessels. The stopper assembly is connected to the adaptor by two connected wires: a bail wire that connects to the stopper assembly, and a lever wire that connects to the adaptor. The inner circumference of the adaptor defines a plurality of vessel threads that engage with the threads defined by the neck of a screw-top vessel. The lever wire is readily removable from the adaptor in order to secure the protruding portions of the lever wire beneath the stop ring of the vessel.
Claims11
A closure device including:
- A. A stopper assembly;
- B. A bail wire rotatably engaged with said stopper assembly;
- C. A lever wire engaged with said bail wire;
- and
- D. An adaptor having an outer circumference and an inner circumference and defining two apertures spanning the outer circumference to the inner circumference of said adaptor wherein said lever wire terminates in two protruding portions releasably engaged with said apertures, wherein said inner circumference defines a plurality of threads configured to engage with compatible threads on the outer neck surface of a vessel and wherein said protruding portions terminate inwardly of said inner circumference and below a stop ring defined by said outer neck surface.
A closure system including:
- A. A vessel having a neck defining a stop ring and a plurality of vessel threads;
- and
- B. A closure device including stopper assembly;
- a bail wire rotatably engaged with said stopper assembly;
- a lever wire engaged with said bail wire;
- and an adaptor having a plurality of threads engaged with said vessel threads and defining two apertures spanning the outer circumference to the inner circumference of said adaptor wherein said lever wire terminates in two protruding portions releasably engaged with said apertures such that said protruding portions terminate inwardly of said inner circumference and below said stop ring, wherein said stopper assembly is configured to enter into and withdraw from said neck.
A method of closing a vessel including the acts of:
- A. Removing a lever wire from an adaptor of a closure device;
- B. Positioning said adaptor on the neck of a vessel having vessel threads;
- C. Rotating said adaptor to engage threads of said adaptor with said vessel threads of said vessel;
- D. Aligning a stopper assembly of said closure device to a position adjacent said neck;
- and
- E. Pivoting said lever wire of said closure device to insert said stopper assembly into said neck.
