A container has a base, peripheral walls and a lid. Each of the base, peripheral walls and lid includes an interior wall spaced from an exterior wall, with vacuum panel in between. The sides of the vacuum panels are covered by compressible insulation fill, minimizing thermal flow along the vacuum panels despite any manufacturing tolerance differences in the width of the vacuum panels as compared to the distance between the interior wall and the exterior wall. The interior wall of the body of the container is provided by a liner formed of a single, deep drawn sheet of material. The exterior wall is similarly formed as a deep drawn shell. The inner liner and the outer shell are welded together with a bead to encase the vacuum panels in a water-tight manner, with the liner, the shell the bead all formed of the same material.

[ What is claimed is:] [1.]1. An insulated container comprising:interior wall;exterior wall surrounding the interior wall, with a space between the interior wall and the exterior wall, the interior wall and the exterior wall defining a plurality of generally planar sides of the insulated container each planar side having a length and a width;vacuum panels disposed in the space between the interior wall and the exterior wall, each vacuum panel having a first side toward the interior wall and a second side toward the exterior wall, with a thickness between the first side and the second side, each vacuum panel having a length and a width which exceeds the thickness, each vacuum panel extending over a substantial entirety of the length and the width of one of the planar sides of the insulated container; andcompressible insulation fill in the space between the interior wall and the exterior wall, the compressible insulation fill being about as long or longer than the length of each of the planar sides and being about as wide or wider than the width of each of the planar sides such that the compressible insulation fill extends along a substantial entirety of at least one of the first and second sides of the vacuum panel, the compressible insulation fill being flexible, wherein the compressible insulation fill comprises a sheet material layer formed independently of the vacuum panel with a generally uniform thickness, the sheet material layer being individually wrapped entirely around both the first and second sides of each vacuum panel.
