Abstract
Abstract For use with a bottle containing pressurized carbonated water-based liquid contents and having an elongated neck portion with at least one annular flange adjacent its mouth, a corking unit of a one-piece elastomeric construction comprising a stopper with a head and a ring below and spaced from the head and molded and concentric with the stopper, the ring being located above the flange upon initial reception of the stopper in the neck, the internal diameter of the ring being slightly less than the internal diameter of the flange and the ring being capable of being pushed down mechanically over the flange in order to be above to be expanded upon passage over the flange and to constrict below the flange for captive retention on the neck, and a set of flexible elongated tethers having one end connected to the ring and the other to the head, the points of connection of the tethers to the ring being mutually spaced and the points of connection of the tethers to the head being mutually spaced, the tethers being folded as molded and each tether having a length as molded substantially greater than the distance between its ends as molded, each tether including a pair of branches and a retroverted bend interconnecting the same, the retroverted bend of one tether facing and being adjacent the retroverted bend of the other tether, and an energy-absorbing link joining the retroverted bends and molded in one piece with the tethers, said link assimilating a portion of the force that would tend to propel the stopper away from the neck upon removal of the stopper from the neck.

Claim 1
Independent Claim
396 words
For use with a bottle containing pressurized, carbonated, water-based, liquid contents and having: a body portion; an elongated neck portion; and a mouth portion, said neck portion having at least one circumferential squat, annular flange adjacent to the mouth portion; a corking unit of a molded one-piece elastomeric plastic construction, said corking unit comprising: (a) an elongated, generally circular, cylindrical sleeve, insertable with frictional engagement through the mouth portion into the neck portion of the bottle; (b) a head connected to the sleeve; (c) an annular, circumferential ring, shaped for reception on the neck portion of the bottle above the annular flange, said ring being positioned and spaced below the head as molded and being concentric with the sleeve, said ring being located above the flange upon initial reception of the sleeve on the neck portion with the ring above the flange, the internal diameter of the ring being slightly less than the external diameter of the flange and the ring being expandable when mechanically pushed down over the flange in order to descend past the flange and constrict below the flange so as to be captively retained on the neck portion of the bottle below the flange; and (d) at least one set of flexible elongated tethers constituting a pair of tethers, each tether of said pair having one end connected to the ring and the other end connected to the head, said tethers joining the ring to the head, the points of connection of the tethers of each pair to the head being spaced from one another and the points of connections of the tethers to the ring being spaced from one another, the tethers of each pair being in a folded state as molded and each tether having a length as molded substantially greater than the distance between its ends as molded, each tether including at least a pair of branches and a retroverted bend interconnected thereby, at least one retroverted bend of one tether on the set having its closed end facing and adjacent to the closed end of the retroverted bend of the other tether and joined thereto by an energy-absorbing link molded in one piece with the tethers, said link assimilating a portion of the force that would tend to propel the sleeve away from the neck portion of the bottle upon removal of the sleeve from said neck portion.
Claim 2
Dependent Claim
396 words
For use with a bottle containing pressurized, carbonated, water-based, liquid contents and having: a body portion; an elongated neck portion; and a mouth portion, said neck portion having at least one circumferential squat, annular flange adjacent to the mouth portion; a corking unit of a molded one-piece elastomeric plastic construction, said corking unit comprising: (a) an elongated, generally circular, cylindrical sleeve, insertable with frictional engagement through the mouth portion into the neck portion of the bottle; (b) a head connected to the sleeve; (c) an annular, circumferential ring, shaped for reception on the neck portion of the bottle above the annular flange, said ring being positioned and spaced below the head as molded and being concentric with the sleeve, said ring being located above the flange upon initial reception of the sleeve on the neck portion with the ring above the flange, the internal diameter of the ring being slightly less than the external diameter of the flange and the ring being expandable when mechanically pushed down over the flange in order to descend past the flange and constrict below the flange so as to be captively retained on the neck portion of the bottle below the flange; and (d) at least one set of flexible elongated tethers constituting a pair of tethers, each tether of said pair having one end connected to the ring and the other end connected to the head, said tethers joining the ring to the head, the points of connection of the tethers of each pair to the head being spaced from one another and the points of connections of the tethers to the ring being spaced from one another, the tethers of each pair being in a folded state as molded and each tether having a length as molded substantially greater than the distance between its ends as molded, each tether including at least a pair of branches and a retroverted bend interconnected thereby, at least one retroverted bend of one tether on the set having its closed end facing and adjacent to the closed end of the retroverted bend of the other tether and joined thereto by an energy-absorbing link molded in one piece with the tethers, said link assimilating a portion of the force that would tend to propel the sleeve away from the neck portion of the bottle upon removal of the sleeve from said neck portion.
Claim 3
Dependent Claim
17 words
A corking unit as set forth in claim one in which there are two sets of tethers.
Claim 4
Dependent Claim
44 words
A corking unit as set forth in claim 1 in which there is at least one short frangible bridge connecting at least one tether to some other element of the unit, said frangible bridge being broken when the ring is forced over the flange.
Claim 5
