  • the transparent lid provides lateral stability for trays when stacked and avoids the increasing cost that results from the eggs being damaged or broken.
  • the nestable egg tray packaging system disclosed by this patent is a significant advance in the field of packaging systems, when used the egg placed in the pocket will be easily broken if more stackable molded fiber nestable egg tray packaging systems placed on top of each other. This is due to the fact that there is no air space provided between the lid and the base of each egg tray packaging system and therefore the weight of eggs from the top packaging system is applied directly to the eggs at bottom packaging system and the risk of breakage or instability has not been reduced to any considerable extent. In addition, due to the close proximity of each egg placed between them, air ventilation between the eggs in the packaging system in this patent is unlikely to occur. Therefore, a heat will be built-up in the packaging system due to humid weather and subsequently has caused the eggs to be rotten.
  • Plastic egg cartons have been provided with flexible walls between the cell pockets to protect the eggs and stop the eggs from going into adjacent cell pockets.

Abstract

La présente invention concerne un casier à œufs thermoplastique empilable (100) et un carton d'emballage d'œufs. Plus précisément, la présente invention concerne un emballage d'œufs qui permet d'empiler et de palettiser un carton d'emballage d'œufs, c'est-à-dire, d'empiler un emballage sur un autre emballage sur une palette, qui peut être facilement déplacée d'un emplacement à un autre emplacement. L'un des avantages de la construction améliorée de carton d'emballage d'œufs est une protection améliorée des œufs lorsqu'ils sont empilés en un agencement stable de sorte que, lorsque physiquement déplacés sur une palette, la multitude de cartons empilés remplis d'œufs peuvent être transportés sans risquer de chuter de la palette, de sortir de l'agencement empilé, et/ou autrement de bouger ou de s'affaisser provoquant l'endommagement des œufs. Un autre avantage du carton d'emballage d'œufs amélioré est de permettre la circulation d'air dans l'ensemble du carton d'emballage d'œufs par l'intermédiaire d'un volume d'air et d'un espace permettant de faire circuler l'air et de prolonger la fraîcheur des œufs.
