A bottle includes a neck and an opening at an end of said neck. A closure member closing the opening is provided with locking means that secure the closure member to a rim of the opening. The locking means include a collar surrounding a neck portion of the neck and locking-levers that are hingedly connected to the collar. The closure member includes outwardly extending lugs that register with the locking-levers. The locking-levers include link members that releasable engage the lugs at a top surface thereof. The locking-levers are retractable to a closed position in which the link members clamp the closure member to the rim of the opening.

The bottle-sealing and preservation device provides for the sealing of necked bottles, including those designed to hold pressure such as champagne bottles, using mechanical advantage to compress an O-ring against the inner surface of the bottle neck. The device can accommodate a wide range of bottle-neck diameters and includes a stabilizing ring that engages the bottle mouth. Optionally, the device may be fitted with a cylindrical cage in which an oxygen-scavenging sachet may be inserted to pull oxygen out of the bottle headspace, thereby preserving any remaining liquid therein that is susceptible to oxidation.

A closure comprises a cylindrical element (1, 101) having a first portion (2, 102) and a second portion (3, 103), the latter being adapted to engage, as a removable cap, in a portion of a neck (5) of a container, an overcap (8, 108) attached to the cylindrical element (1, 101), comprising a first body (9, 109, 209) and a second body (15, 115, 215), attached together and defining a seat (19, 219). The cylindrical element (1, 101) is partially disposed in the seat (19, 219) to be locked within the seat (19, 219).

A rigid stopper (10) made of bisphenol-free polycarbonate and silicone synthetic materials, particularly for a wine bottle (48), comprises a cylindrical body (12) and two opposing faces (16, 18), and at least two compressible-elastomeric “O”-rings (22, 24) seated in corresponding circumferential grooves (26, 28) on a side (14) of the body (12). The faces (16, 18) are comprised of foramen (42, 44) respectively which communicate with a volute-cavity (40) for the purpose of accepting a cork-screw-extractor. The volute-cavity (40) is comprised of a partition (46) at a central-plane (56) for the purpose of preventing wine from leaking through the volute-cavity (40). “O”-rings (22, 24) are compressively forced into a mouth (50) of a bottle (48) positioning either face (16) or face (18) flush with the mouth (50) thereby providing adequate compressive force in maintaining position of the stopper (10). Stopper (10) having longitudinal symmetry about a central plane (56), either face (16) or (18) of stopper body (12) maintains compatibility with random orientation of the stopper (10) in “corking” process of packaging.

The invention relates to a biodegradable stopper comprising a casing of rigid biodegradable material, consisting of an annular body with a covered flank, and an internal ring of biodegradable elastic material the total width of which is equal to or smaller than the internal width of the annular body, comprising one or more internal recesses in which one or more portions of the ring fit.

The invention relates to a capsule (1) for a flanged cork stopper, the capsule (1) having a body (2) comprising a top (3) and a cavity (4) inside which at least two anti-rotation splines (5) are arranged, and the capsule further comprising an axial retention chamber (6) disposed within said cavity (4), wherein retention chamber (6) is shaped to receive and axially retain a flange of a flanged cork stopper. The invention also relates to a capsulated stopper comprising a flanged stopper, the flange of which is attached to the capsule (1) of the invention. The invention further relates to the production process of said capsulated stopper.
