发明名称 Egg carton having spring-release opening mechanism
摘要 An egg carton is fabricated of a single sheet of resilient material such as foam plastic or the like to define a multi-celled bottom tray coupled to a correspondingly shaped tray cover by a resilient hinge. The forward portion of the bottom tray further defines a latch flap secured to the bottom tray by a resilient hinge. The latch flap defines a pair of projections which are received within a corresponding pair of apertures formed in the tray cover. A notch is formed in the tray cover which exposes a portion of the latch flap allowing the user to force the latch flap inwardly and release the cover latch. With the latch released, the resilience of the tray cover hinge causes the cover to spring open exposing the carton contents.
