A container including a support structure defined by a side wall portion and a bottom wall portion. An upper portion is integrally attached to the support structure, where the upper portion is formed of a flexible material defining opposing portions. The flexible material has a lower stiffness than a stiffness of the side wall portion, and the opposing portions are movable between a closed position located in engagement with each other and an open position where the opposing portions are separated from each other defining an opening to an interior area of the container. A frangible portion is provided on the upper portion forming a predefined separation line for separating at least a portion of the upper portion from the support structure
