An insulated container comprising:

• a double-walled structure comprising a closed end and an open end, and a side wall extending between the closed and open ends, wherein the side wall and the closed end together form a hollow interior, wherein the side wall comprises an inner surface wall, an outer surface wall, and a sealed rim at the open end sealing a space between the inner surface wall and the outer surface wall;
• an inner structure removably arranged within the hollow interior, the inner structure comprising
• a body having an open upper end and a base end, and
• a sipping portion extending from the open upper end, the sipping portion comprising a sipping end and a shoulder end spaced apart from the sipping end,
• wherein the sipping portion protrudes from the open end of the double-walled structure and is seated with the shoulder end atop the rim of the double-walled structure;
• and
• a collar comprising a first skirt, a second skirt, an end wall extending between the first skirt and the second skirt, and an opening in open communication with the open upper end of the inner structure,
• wherein the end wall covers the sipping end and forms a sipping surface, the first skirt extends beyond the shoulder end of the sipping portion of the inner structure to contact the outer surface wall of the double-walled structure and is threadingly secured to the outer surface wall of the double-walled structure, and the second skirt extends into an interior of the inner structure,
• wherein the sipping portion of the inner structure is disposed between the end wall of the collar and the sealed rim of the open end of the double-walled structure, and
• wherein the collar removably secures the inner structure to the double-walled structure.
