Patent

CA 2416972

The present invention is directed to rigid disposable food containers provided with a relatively steep sidewall with a generally linear profile and an outwardly flared arcuate flange portion. The containers are further characterized by a flange outer vertical drop wherein the ratio of the length of the vertical drop to the characteristic diameter of the container is greater than about 0.01. By virtue of unique geometry, the containers of the invention exhibit improved rigidity and/or rim stiffness yet have favorable runnability in pressware manufacturing systems characteristic of plates of lower strength.

La présente invention se rapporte à des contenants alimentaires jetables rigides dotés d'une paroi latérale relativement abrupte avec un profil généralement linéaire et d'un rebord arqué évasé vers l'extérieur. Les contenants se caractérisent également par une dénivellation extérieure du rebord, de sorte que le rapport de la longueur de la dénivellation au diamètre caractéristique du contenant soit supérieur à environ 0,01. Grâce à leur géométrie unique, les contenants prévus par l'invention présentent une rigidité et/ou une dureté de bordure améliorées, tout en affichant une exécutabilité favorable dans les systèmes de fabrication de verre pressé caractéristiques d'assiettes moins solides.
