DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 1 illustrates a beverage server 10 in accordance with an illustrative embodiment of the present disclosure as including an assembly of a container 12 and an insulator 14 coupled to the container 12. The insulator 14 includes an insulator shell 16 carrying the container 12, and an annular fitment 18 coupled to the shell 16. The fitment 18 may be a seal for sealing between the shell 16 and the container 12 to establish a sealed insulating air pocket 13 (FIG. 2) therebetween, so as to maintain a desired temperature of a beverage in the container 12.

With reference to FIG. 2, the container 12 may be a bottle that may be composed of glass, and that may have a base 20, a sidewall or body 22 extending from the base 20 in a direction along a longitudinal axis A of the container 12, a shoulder 24 extending from the body 22, a neck 26 extending from the shoulder 24, and a neck finish 28. The base 20 may be circular and may include a push-up 34. Likewise, the body 22 may be circular in transverse cross section, and may include a recessed label surface or panel 36. The body 22 may include exterior surfaces 35, 37 on either axial side of the label panel 36. The shoulder 24 may include an excurvate portion 24a adjacent the body 22 and an incurvate portion 24b between the excurvate portion 24a and the neck 26. The neck finish 28 may include a capping flange 30 and/or any suitable closure engagement feature(s) 32. As such, the container 12 may be part of a package that may include a beverage (not shown) carried in the container 12, and a cap or other closure (not shown) that may be coupled to the closure engagement feature(s) 32. The particular geometry of the container 12 illustrated in the Figures is illustrative only.

The insulator shell 16 may be composed of glass, for example, a soda lime silica glass or a borosilicate glass. The shell 16 includes a base 38, a hollow body 40 extending from the base 38 and terminating in an open end 42. The base 38 may correspond to the base 20 of the container 12, and for example, may include a push-up 44 that may correspond to the container push-up 34. The open end 42 may include a bead 46 for coupling to the fitment 18. Although only one external bead is illustrated, the shell 16 may include any suitable quantity of such beads, which may project radially outwardly (as shown) and/or radially inwardly.

The fitment 18 may include an axial rim 48, a radially outer flange 50 extending from a lower portion of the rim 48, and a radially inner flange 52 spaced radially inwardly from the outer flange 50 and extending from the lower portion of the rim 48. The rim 48 may be configured and sized for firm coupling over the open end 42 of the shell 16 and, for instance, may include a slot established by the flanges 50, 52 and that may be secured by snap-fit to the open end 42 of the shell 16. For example, the radial space between the flanges 50, 52 may be less than the wall thickness of the shell 16. Also, in the illustrated embodiment, the outer flange 50 may include a radially inwardly extending internal bead 56 for snap-fit engagement over the external bead 46 of the shell 16. In other embodiments, the inner flange 52 may include a radially outwardly extending bead (not shown) for snap-fit engagement within a radially inwardly extending bead (not shown) of the shell 16. Any other suitable arrangement of interengaging beads or the like may be used for snap-fit engagement of the fitment 18 to the shell 16.

The fitment 18 also may include a lip 54 extending radially and axially inwardly from the rim 48. The lip 54 may extend, for instance, from an upper portion of the rim 48 distal with respect to the flanges 50, 52, or from any other suitable portion of the rim 48. In one implementation, the lip 54 may be completely circumferentially continuous so as to provide a particularly good seal with the container 12. In another implementation, the lip 54 may include a plurality of circumferentially spaced slits extending radially inwardly from a radially innermost edge of the lip 54, for example, to facilitate flexibility of the lip 54. The slits may not extend completely radially through the lip 54, such that the lip 54 may be circumferentially continuous between ends of the slits and the rim 48 so that the lip 54 may provide a complete annular seal with the container 12.

Therefore, the lip 54 may be flexible and resilient, and sized to permit insertion of the container 12 through the fitment into the shell 16 with the lip 54 in engagement with an exterior surface of the container 12. For example, the lip 54 may be in direct contact with the exterior surface of the excurvate portion 24a of the shoulder 24. Accordingly, the lip 54 need not interfere with the label panel 36 of the body 22. In other embodiments, the lip 54 may be in contact with the body 22. Finally, the fitment 18 may be composed of a polymeric material, for instance, a thermoplastic, thermoset, or elastomeric material, for example, rubber or silicone, or of any other suitable material. Accordingly, the fitment 18 may be composed of a glass-recycling-friendly material, so as to enable complete glass recyclability of the entire server.

In an embodiment where the shell 16 is glass, the shell 16 may be desirable for use as a drinking glass into which contents from the container 12 may be poured. Accordingly, the shell 16 facilitates ready consumption of the contained beverage via a glass drinking glass.

FIG. 4 shows another illustrative embodiment of a beverage server 110. This embodiment is similar in many respects to the embodiment of FIGS. 1-3 and like numerals among the embodiments generally designate like or corresponding elements throughout the several views of the drawing figures. Accordingly, the descriptions of the embodiments are incorporated into one another, and description of subject matter common to the embodiments generally may not be repeated here.

The server 110 includes the container 12, and an insulator 114 coupled to the container 12 and including a glass shell 116 carrying the container 12, an annular glass bead 118 between the shell 116 and the container 12, and a cushion 160 separate from the container 12 and insulator 114 and positioned between the container 12 and the shell 116.

The shell 116 includes a closed base 138 and an open end 142, and carries the container 12 therein such that the base 138 of the insulator 114 carries the base 20 of the container 12.

The cushion 160 may be assembled into the insulator shell 116 and carried by an interior surface of a base 138 of the shell 116. The cushion 160 may be a ring shaped component with an inner void 161 to accommodate and encircle a push up 144 of the insulator shell 116. In other embodiments, the cushion 160 may be a radially continuous disc that conforms to the base 138 of the shell 116. The cushion 160 may be composed of any suitable material, including any suitable polymeric material, for instance, a thermoplastic, thermoset, or elastomer, for example, silicone. The cushion 160 may be produced by injection molding, casting, or in any other suitable manner.

The glass bead 118 may couple the shell 116 to the container 12 in any suitable manner. The glass bead 118 may be in complete circumferentially continuous contact with the open end 142 of the glass shell 116 and the container 12. For example, the bead 118 may be an integral portion of the container 12 and the shell 116. More specifically, the bead 118 may be a glass weld head integrally fused to corresponding portions of the container 12 and the shell 116. For instance, the bead 118 may be integrally fused to the open end 142 of the shell 116 and to the shoulder 24 of the container 12. The open end 142 of the shell 116 may be tapered from the straight wall of the shell 116, for example at a forty-five degree angle. In any case, the bead 118 may provide a seal between the shell 116 and the container 12 to establish a sealed insulating air pocket 113 therebetween, so as to maintain a desired temperature of a beverage in the container 12.

After the individual components are manufactured, the cushion 160 may be assembled inside the shell 116, the container 12 may be assembled into the shell 116 in contact with the cushion 160, and then the bead 118 may be applied to the container 12 and the shell 116 by any suitable glass welding technique, or in any other suitable manner.
