Container having a rim or other feature encapsulated by or formed from injection-molded material

A method of forming a container from a blank, the method comprising:

• providing a tool having a cavity, a core, and an articulated section for being moveable within the cavity relative to the cavity and the core;
• placing the blank between the cavity and the core;
• moving the core relative to the cavity so that the articulated section at least partially initially grips a portion of the blank;
• further moving the core into the cavity to form the blank into the container, the portion of the blank remaining gripped by the articulated section in the cavity during the further moving of the core, and the cavity at least partially shaping the container,
• wherein the articulated section contacts at least one sidewall of the container formed from the blank when the blank is at least partially initially gripped by the articulated section and the articulated section has a bottom portion and at least one upstanding sidewall portion extending upward from the bottom portion, the bottom portion contacting the bottom wall of the container and the sidewall portion contacting the at least one sidewall of the container.

A tool for forming a container, the tool comprising:

• a cavity for receiving a blank, and for at least partially defining a shape of the container formed from the blank;
• a core operatively associated with the cavity, the core being operable to move within the cavity to at least partially form the blank into the container;
• and
• at least one articulated section movably received in the cavity, the articulated section being for initially gripping a portion of the blank to hold the blank as the core is further moved into the cavity to form the blank into the container, the articulated section comprises a first articulated section and a second articulated section, the first articulated section is at least partially received in the second articulated section when the core is received in the cavity for forming the container from the blank.

• wherein the articulated section comprises a first articulated section and a second articulated section, the initially gripping of at least a portion of the blank occurs when the first articulated section grips a portion of the blank corresponding to a bottom wall of the container formed from the blank, the further moving of the core into the cavity comprises moving the first articulated section relative to the second articulated section.
