    • An expandable food carton expands to a non-trapezoidal shape when in an open and expanded state. The expanded state creates a wider top opening which provides a larger access to the interior of the package and thus to the food product. The expandable carton has a bottom end with upstanding side panels therefrom, where each side panel has at least one score line that extends between an upper end region and a lower end region. The carton has a top flap attached at an upper end of each side panel, each top flap also having a score line that extends longitudinally between an upper end region and a lower end region at a midpoint region. Upon shifting the carton into the expanded state, the side panels of the carton shift outward along their respective score lines and the top flaps of the carton fold down adjacent respective side panels and shift outward along their respective score lines.
    • 当处于开放和膨胀状态时,可膨胀食品纸箱膨胀成非梯形。 膨胀状态产生更宽的顶部开口,其提供更大程度地进入包装的内部并因此提供给食品。 可膨胀纸箱具有底部,其底部具有直立的侧面板,其中每个侧板具有至少一个在上端区域和下端区域之间延伸的刻痕线。 纸箱具有附接在每个侧板的上端的顶部翼片,每个顶部翼片还具有在中点区域的上端区域和下端区域之间纵向延伸的刻痕线。 当将纸箱移动到膨胀状态时,纸箱的侧板沿其各自的刻痕线向外移动,并且纸箱的顶部折板相邻于相应的侧板折叠并沿其各自的刻痕线向外移动。
