A method of forming a container from a construct. The method includes obtaining a tool having a cavity, a core, and an articulated section for being moveable within the cavity relative to the cavity and the core. The method further includes placing a construct 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 construct, and further moving the core into the cavity. The portion of the construct remains gripped by the articulated section in the cavity during the further moving of the core.

1. A method of forming a container from a construct, the method comprising: obtaining a tool having a cavity, a core, and an articulated section for stabilizing a position of the construct in the tool and for being moveable within the cavity relative to the cavity and the core, the cavity having at least one sidewall surface, the articulated section having a sidewall surface aligning with the at least one sidewall surface of the cavity, the sidewall surface of the articulated section and the at least one sidewall surface of the cavity are each configured to form a portion of at least one sidewall of the container;placing a construct between the cavity and the core;moving the core relative to the cavity to form the interior space of the container so that the articulated section at least partially initially grips a portion of a sidewall of the construct; andfurther moving the core into the cavity for further forming the construct into the container, the portion of the sidewall of the construct remaining gripped by the articulated section in the cavity during the further moving of the core, the further moving the core into the cavity comprises forming the at least one sidewall of the container by pressing the at least one sidewall of the container in contact with the sidewall surface of the articulated section and the at least one sidewall surface of the cavity when the core is moved into the cavity. 2. The method of claim 1 wherein the articulated section contacts a portion of a bottom wall of the construct when the construct is at least partially initially gripped by the articulated section. 3. The method of claim 1 wherein the articulated section contacts at least one sidewall of the construct when the construct is at least partially initially gripped by the articulated section. 4. The method claim 1 wherein the articulated section has a bottom portion and at least one upstanding sidewall portion extending upward from the bottom portion, the bottom portion contacting a bottom wall of the construct and the at least one upstanding sidewall portion contacting the sidewall of the construct. 5. The method of claim 1 wherein the articulated section comprises a first articulated section and a second articulated section, the initially gripping of at least a portion of the construct occurs when the first articulated section grips a portion of the construct corresponding to a bottom wall of the construct. 6. The method of claim 5 wherein the further moving of the core into the cavity comprises moving the first articulated section relative to the second articulated section. 7. The method of claim 6 further comprising moving the core into the cavity so that the second articulated section grips at least a portion of the construct after the initial gripping by the first articulated section. 8. The method of claim 7 wherein the gripping by the second articulated section occurs when a portion of the sidewall of the construct is received in the second articulated section. 9. The method of claim 1 further comprising fully closing the core and the cavity so that the core is fully inserted into the cavity to form the container from the construct. 10. The method of claim 9 wherein the closed core and cavity provide space for side corners of the container to bulge outward. 11. The method of claim 9 further comprising forming an injection-molded feature on the container. 12. The method of claim 11 wherein the container comprises a sidewall and a flange extending laterally from the sidewall, and forming the injection-molded feature comprises at least partially encapsulating the flange. 13. The method of claim 12 wherein the forming of the injection-molded feature comprises injecting injection-molding material into an injection cavity of the tool and cooling the injection-molding material, wherein the injecting of the injection-molding material comprises injecting injection-molding material into an advanced-flow section of the injection cavity and thereafter injecting injection-molding material into a delayed-flow section of the injection cavity. 14. The method of claim 1 wherein the articulated section contacts a central portion of the construct. 15. The method of claim 1 wherein the construct is a blank. 16. The method of claim 1 wherein the construct is a tray. 17. The method of claim 1 wherein the further moving of the core into the cavity comprising moving the at least one articulated section in slidable contact with the at least one sidewall surface of the cavity. 18. The method of claim 1 wherein the core has an external surface shaped to cooperate with the at least one sidewall surface of the cavity, the further moving of the core into the cavity comprises pressing a portion of the construct between the external surface of the core and the at least one sidewall surface of the cavity to form the sidewall of the container.
