  • the plurality of cavities may be distributed substantially non-uniformly around the side wall 330.
  • the plurality of grooves are not limited to being generally triangular in cross section as described above, but may instead be generally semi-circular, square, rectangular, or oval in cross section.
  • the plurality of grooves in the side wall 330 are not limited to being of the same cross-section, but instead, the grooves (not shown) around the side wall 330 may be comprised of a combination of cross sections.
  • the food grade container 300 may further comprise insulation (not shown) such as, for example, polyurethane foam, disposed within each of the plurality of cavities defined between the outer surface 335 of the first body 310 and the inner surface 353 of the housing portion 350.
  • insulation such as, for example, polyurethane foam
  • the plurality of grooves in the side wall 330 are not limited to extending vertically from the base 320 to the opening 340, but may instead be horizontally or diagonally disposed around the side wall 330.
  • the food grade container 300 may further comprise a container lid (not shown) so as to close the food grade container 300 in use.
  • Figure 7 shows an alternative embodiment of a food container lOd, which is similar to the food container 10.
  • the elongated cavities 60d are substantially oval or oblong in cross section.

Abstract

La présente invention se rapporte à un récipient de qualité alimentaire possédant une structure à deux parois qui a pour avantage d'isoler le contenu de l'environnement et également d'améliorer la rigidité structurale de l'élément lors de l'utilisation. De multiples cavités sont formées entre les deux parois conçues pour contenir une barrière d'air isolante. La structure géométrique des cavités améliore l'intégrité structurale par l'apport d'un support pour chaque paroi et l'amortissement du mouvement dans une ou les deux parois lorsqu'elles sont constituées d'un élastomère.
