Abstract
A forming tool for forming a container from a blank is disclosed. The forming tool has a cavity and a core. The cavity has an articulating portion moveably connected to a cavity base. The core has a nose moveably connected to a nose base. When the container is formed from the blank, the nose is moved relative to the nose base prior to moving the articulating portion relative to the cavity base.
Claims23
A tool for forming a construct from a blank, the tool comprising:
- a cavity operable to receive a blank, the cavity comprising an articulating portion and a cavity base, the articulating portion being moveably connected to the cavity base, the cavity comprising at least one cavity spring for controlling movement of the articulating portion relative to the cavity base;
- a core operatively connected to the cavity, the core being operable to enter the cavity to at least partially form the blank into a construct, the core comprising a core base and a nose being moveably connected to the core base, the core comprising at least one core spring for controlling movement of the nose relative to the core base,
- the at least one cavity spring having a first strength, and the at least one core spring having a second strength, the first strength being greater than the second strength.
A method of forming a construct from a blank, the method comprising:
- obtaining a blank;
- placing the blank in a forming tool, the forming tool comprising a cavity having a articulating portion, a cavity base, and at least one cavity spring for controlling movement of the articulating portion relative to the cavity base, and a core comprising a core base, a nose, and at least one core spring for controlling movement of the nose relative to the core base;
- closing the tool while the blank is in the tool,
- the closing the tool comprising pressing the core against the blank to compress the at least one core spring and further moving the core to cause the articulating portion to move relative to the cavity base, the at least one core spring being compressed prior to receiving the core into the cavity to complete formation of the blank into the construct.
