Abstract
An anvil device (10) is for insertion into an end closure of a partially formed container. The anvil device (10) comprises a bracket (12) and an anvil body (14) connected to one end of the bracket (12). The anvil body (14) comprises four corners (C1 to C4) where the distance between one pair of diagonally opposite corners (C1, C3) is less than the distance between the other pair of diagonally opposite corners (C2, C4). The anvil body (14) is asymmetric and one corner (C1) is closer to the centre of the anvil body (14) than each of the other three corners (C2 to C4).

An anvil device (10) for insertion into an end closure of a partially formed container (16), the anvil device (10) comprising:
- bracket (12), and
- an anvil body (14) connected to one end of the bracket (12), the anvil body (14) comprising four corners (C1-C4), the distance between one pair of diagonally opposite corners (C1, C3) being less than the distance between the other pair of diagonally opposite corners (C2, C4), characterized in that one corner (C1) is closer to the center of the anvil body (14) than each of the other three corners (C2, C3, C4).
A method of forming an end closure of a partially formed container (1 6), the method comprising:
- receiving the partially formed container (16),
- inserting into an opening of the end closure an anvil device (10) comprising a bracket (12), and an anvil body (14) connected to one end of the bracket (12), the anvil body (14) comprising four corners (C1-C4), the distance between one pair of diagonally opposite corners (C1, C3) being less than the distance between the other pair of diagonally opposite corners (C2, C4), wherein one corner (C1) is closer to the center of the anvil body (14) than each of the other three corners (C2, C3, C4), and
- pressing externally on the end closure of the partially formed container (16).
