Tool for forming a container

A tool for forming a container from a construct, the container comprising a bottom wall and at least one sidewall foldably connected to and extending upwardly from the bottom wall to form an interior space of the container, the tool comprising:

• a cavity for receiving a construct, the cavity having at least one peripheral wall for at least partially forming the sidewall of the container;
• a core operatively associated with the cavity and being operable to move within the cavity to position the at least one sidewall of the container relative to the bottom wall to form the interior space;
• and
• at least one articulated section movably received in the cavity, the at least one articulated section being for gripping at least a portion of the at least one sidewall of the construct, and configured for stabilizing a position of the construct in the tool, when the core is moved relative to the cavity to form the interior space of the container, the at least one articulated section being configured for gripping at least a portion of the at least one sidewall of the construct and moving with the construct and the core in the cavity as the core is further moved into the cavity for further forming the construct into the container, the articulated section having a wall surface cooperatively aligning with the at least one peripheral wall surface of the cavity, the articulated section wall surface and the cavity peripheral wall surface are each configured to form a portion of the at least one sidewall of the container when the core is moved into the cavity.
