DETAILED DESCRIPTION

[0020] FIG. 1 is a front isometric view of an aluminum wine bottle 10. In this example embodiment, the aluminum wine bottle 10 has a constant diameter barrel portion 12, a varying diameter shoulder portion 14 and a varying diameter neck portion 16. A wine bottle outsert 40 is fixedly mounted on the bottle neck portion 16 below a rolled end portion 18 of the bottle neck 16. An ST capsule 30 that is to be mounted on the bottle 10 is positioned next to the bottle 10. The ST capsule 30 has a generally tubular shape with an upper closed end 31 and a lower end 33 that has a circular bottom opening. The capsule 30 has an upper, screw cap portion 32 and a lower, skirt portion 34 that is connected to the screw cap portion 32 by a perforated connection portion 36. The ST capsule may be a conventional ST capsule of the type used on glass wine bottles. In one example embodiment, the ST capsule 30 is a “crimp on the bottle” type ST capsule. In another example embodiment, the ST capsule 30 is a prethreaded ST capsule.

[0021] FIG. 2 is a front isometric view of an aluminum wine bottle 10 with the ST capsule 30 fixedly attached to it. In one example embodiment, the ST capsule is a “crimp on the bottle” type ST capsule and is attached to the outsert by crimping the cap portion 32 of the bottle onto the threaded outsert 40 with a rotating crimping assembly. In another example embodiment, the ST capsule is a prethreaded ST capsule and is attached to the outsert by screwing the ST capsule onto the outsert threads.

[0022] FIG. 3 is a cross sectional elevation view of an upper portion of the aluminum wine bottle 10 with an outsert 40 loosely positioned thereon. The upper end of the bottle neck portion 16 has an outset mounting region 20 that includes a vertical, constant diameter region 22 and a lower flared region 24 in which the bottle neck diameter becomes progressively larger from the top to the bottom of the region 22. The outsert 40 is initially mounted on the bottle 10 by placing the outsert 40 over the end of the bottle 10 and sliding it downwardly to the position shown in FIG. 4 at which point the bottle neck diameter is sufficiently large to prevent further downward displacement of the outsert 40. In FIG. 3, a small, e.g. 0.115 in, axially extending annular portion 17 of the bottle 10 extends vertically above the outsert mounting region 20. In one example embodiment, the constant diameter region 22 has a diameter of around 0.89 in and an axial length of around 0.48 in, and the varying diameter region 24 has a maximum diameter of about 1.0 in and an axial length of around 0.25 in.

[0023] FIG. 4 is a cross-sectional elevation view of the same portion of the aluminum wine bottle 10 as shown in FIG. 3, but with the outsert 40 fixedly attached to the bottle 10. As in FIG. 3, the flared portion 24 of the bottle mounting region 22 has engaged the inner surface of the outsert 40, preventing any further downward displacement thereof. Then, the annular tip portion 17 of the bottle neck 16, which is shown in FIG. 3, is curled to produce rolled/curled end portion 18. Annular rolled end portion 18, at its lower surface, engages the top annular surface of the outsert 40, preventing upward displacement of the outsert 40. The rolled/curled end portion 18 may be formed, for example, as described in U.S. Pat. No. 9,139,324 of Watkins et al. for METAL BOTTLE TYPE CONTAINER WITH INSERT/OUTSERT AND RELATED METHODOLOGY, issued Sep. 22, 2015, which is hereby incorporated by reference for all that it discloses.

[0024] FIG. 5 is a top isometric view of the wine bottle outsert 40; FIG. 6 is a bottom isometric view thereof; and FIG. 7 is another bottom isometric view thereof. FIG. 8 is a side elevation view thereof. In one example embodiment, the outsert is made of a relatively high strength plastic, for example Polyethylene Terephthalate (“PTE”) or other relatively high strength material such as ceramics. As shown by FIGS. 5-8, the outsert 40 is a tubular member with a generally cylindrical outer surface 56 comprising a threaded upper portion 58 with a continuous thread 60 and an unthreaded lower portion 64. The outsert 40 has upper and lower open ends 42, 44 defined by upper and lower terminal edges 52, 54. The outsert 40 has an annular inner surface 46 with an upper constant diameter region 48, and a lower outwardly flared region 50. The upper terminal edge 52 of the outsert is adapted to engage the rolled end 18 of the bottle 10, preventing the outsert 40 from moving upwardly. The outwardly flared Inner surface region 50 of the outsert 40 is adapted to engage the flared region 24 of the bottle 10 to prevent downward travel of the outsert and maintain it in the position shown in FIG. 2. In one example embodiment, the overall axial length of the outsert 40 is 0.831 in and the thread pitch is 7 threads per inch.

[0025] FIG. 9 is a cross-sectional elevation view of one embodiment of the outsert 40. The outsert dimensions, in inches, are Indicated in Table 1 below, for one example embodiment.

[0026] To produce the bottle/ST capsule assembly shown in FIG. 2, the outsert 40 is slipped over the aluminum wine bottle upper uncurled end 22, as shown in FIG. 3. The flared region 24 of the bottle neck portion 16 acts as the lower limit of travel of the outsert 40. A small axial length, e.g., 0.115 in, of the annular terminal end 17 of the bottle neck portion 16, FIG. 3, is then formed into a rolled/curled region 18 that engages the upper edge portion 52 of the outsert preventing its upward displacement. In one embodiment, as best shown in FIGS. 3 and 7, the upper edge portion 52 comprises an annular nose portion 51 integrally connected to an annular step or ledge portion 53. As shown in FIG. 4 the bottle curl portion 18 is rollingly/curlingly deformed over these portions 51, 53 of the upper edge portion 52, forming a smooth seam at the Interface of the terminal edge of curl portion 18 and the outsert annular ledge portion 53.

[0027] Next the circular bottom opening of the ST capsule 30 is placed over the outsert 40 and the ST capsule 30 is moved axially downwardly relative the outsert 40 and bottle neck portion 16 until the closed end 31 of the capsule 30 engages the curled/rolled portion 18 of the bottle neck portion 16. The ST capsule 30 is then rollingly crimped onto the outsert 40 and bottle neck portion 16 by a machine in the same manner as when it is crimped to the threaded end of a conventional threaded glass bottle. This crimping action forms corresponding female threads in the upper portion 32 of the capsule that provides a twist off cap. In an example embodiment in which the ST capsule 30 is a screw on type ST capsule, the capsule it is displaced downwardly until the threaded portion of the capsule 30 reaches the threaded portion of the outsert 40. Then the capsule 30 is screwed on to the outsert 40. With either the crimp on or the screw on type ST capsule 30, the perforated connecting portion 36 of the capsule is broken when a consumer twists off the upper portion 32. The upper portion 32 then acts as a recloseable twist cap.

[0028] FIG. 10 is a flow chart for a method of capping an aluminum wine bottle. The method includes, as shown at block 201, attaching an outsert to an aluminum bottle neck portion. The method also includes, as shown at block 202, attaching a wine bottle capping assembly to the outsert.

[0029] Although certain embodiments of metal wine bottle assemblies with twist off capping assemblies and related components and methods have been expressly described in detail herein, alternative embodiments thereof will occur to those skilled in the art after reading this disclosure. The language of the appended claims is intended to be construed broadly to cover all such alternative embodiments, except to the extent limited by the prior art.
