A round beverage container with a chill sleeve is provided having a molded plastic wall in the shape of a cup, a mug, or a pitcher. A sleeve containing a chill medium is in the shape of a truncated conical cylinder, and is positioned in the container to be lodged therein at a selected mounting location and secured by snap-action sealing and retaining rings. A bottom disk, also containing the chill medium, snaps into the container's bottom edge to form the bottom of the container. This bottom disk is sealed to the inside wall of the container by snap-action sealing and retaining rings. Sonic welding can be employed as an alternative to sealing and securing rings. A quantity of water-based chill medium is metered into the hollow cavities when the sleeve and the bottom disk are charged, taking into consideration the expansion of the chill medium (water) upon a change of phase. The wall of the container is tapered and the side walls of the sleeve and of the bottom disk are each tapered to match the taper of the container wall. A bottom face (wall) for each of the insertable chill sleeve and the bottom disk is first separate from the remainder and then snapped into place to seal the respective chill sleeve and bottom disk after they are filled. The bottom face of the chill sleeve is toroidal-shaped.

1. A container for chilling a beverage held therein, comprising: a body having a cylindrical wall with a top lip and a bottom lip openings and an inner and outer faces, said body holding the beverage;a bottom which is hollow and encapsulates a chill fluid;a hollow sleeve insert positioned within said body against said cylindrical wall inner face and positioned above as spaced away from said bottom;wherein said hollow sleeve insert encapsulates a chill fluid;wherein said chill fluid within said bottom and within said sleeve insert freezes at a temperature of 32 F or below and wherein said chill fluid expands upon freezing;wherein said cylindrical wall is frustoconical-shaped with its larger diameter at its bottom;wherein said hollow sleeve insert is frustoconical-shaped with a top and bottom openings and its larger diameter at its bottom;wherein said hollow sleeve insert position against said cylindrical wall is by friction press-fit; andwherein said cylindrical wall inner face carries a plurality of receiving grooves proximate said hollow sleeve insert position, and wherein said hollow sleeve insert outer face carries a plurality of retaining and sealing rings wherein a respective ring of said insert engages a respective groove of said cylindrical wall. 2. A container of claim 1, wherein said chill fluid within said bottom and within said sleeve insert freezes at a temperature in the range of about 28 F to about 32 F;wherein said hollow bottom is frustoconical-shaped with its larger diameter at its bottom; andwherein said hollow bottom and said hollow sleeve insert hold said chill fluid charged there into and each then being sealed, said chill fluid being subjected to a negative pressure, being a partial vacuum, when at room temperature. 3. The container of claim 1, wherein said cylindrical wall inner face carries at least one receiving groove proximate the position of said bottom and wherein said bottom side wall carries at least one retaining and sealing ring wherein said ring engages said groove. 4. The container of claim 1, wherein said cylindrical wall is of solid thermoplastic material selected from the group of HDPE and PVC, wherein said hollow sleeve insert is of thermoplastic material selected from the group of PETE and LDPE and wherein said hollow bottom is of thermoplastic material selected from the group of HDPE and PVC. 5. The container of claim 1, also including a color temperature strip attached to said cylindrical wall outer face. 6. The container of claim 5, wherein said temperature strip extends vertically. 7. The container of claim 1, also including a hollow spiral tower positioned within said container extending upwardly from the center of the container's bottom, said tower containing said chill fluid encapsulated under a negative pressure at room temperature and below. 8. The container of claim 7, wherein the volume of chill fluid encapsulated in said hollow sleeve insert, in said container's hollow bottom, and in said hollow spiral tower is metered to account for expansion upon freezing so that the encapsulation space is essentially filled upon said expansion. 9. The container of claim 7 wherein the top face of said containers hollow bottom includes a socket for holding said hollow spiral tower. 10. The container of claim 1, wherein the containers cylindrical wall, the bottom and the hollow sleeve insert are joined by sonic welding. 11. The container of claim 1, also including a handle mounted on said cylindrical wall outer face, said handle being thermally isolated from said cylindrical wall by insulation pads at its mounting. 12. The container of claim 2, wherein said chill fluid is water and wherein said negative pressure is the result of said water being charged at an elevated temperature. 13. The container of claim 12, wherein said charged water elevated temperature is about 100 F to 125 F. 14. The container of claim 12, wherein said water charge has been metered to take into consideration said expansion upon freezing. 15. The container of claim 14, wherein said hollow sleeve insert bottom wall is toroidal-shaped and wherein said hollow sleeve insert has a solid top extending between the inner and outer faces and an insertable bottom wall. 16. The container of claim 1, wherein said freeze expansion is between about 9 percent and 11.5 percent. 17. The container of claim 16, wherein said hollow sleeve insert position against said cylindrical wall is by friction press-fit. 18. The container of claim 1, wherein said body holds said beverage in direct contact with the surface thereof;said hollow sleeve insert extending the height of said side wall except for a space below said top lip opening and a space above said bottom, whereby said sleeve insert is spaced away from both said top lip and said bottom;wherein said chill fluid is charged into and encapsulated within said hollow sleeve insert and said hollow bottom;wherein said encapsulation is gas and fluid leak resistant; andwherein said encapsulated chill fluid is subject to a negative pressure-partial vacuum when in the fluid state. 19. The container of claim 18 wherein said negative pressure-partial vacuum is the result of charging said chill fluid at an elevated temperature. 20. The container of claim 18 wherein said negative pressure-partial vacuum is the result of charging said chill fluid at a temperature in the range of about 100 F to about 125 F.
