Abstract
A can shell includes a center panel, an inclined panel wall extending at a downward angle from the center panel, an annular countersink formed around the inclined panel wall, the annular countersink including an inner countersink wall and an outer countersink wall, a chuck wall extending from the outer countersink wall, the chuck wall including a kick portion having a curved shape beginning at a point lower than a lowest point of the inclined panel wall, and a curl extending radially outwardly from the chuck wall.
Claims20
A can shell comprising:
- a center panel;
- an inclined panel wall extending at a downward angle from the center panel;
- an annular countersink formed around the inclined panel wall, the annular countersink including an inner countersink wall and an outer countersink wall;
- a chuck wall extending from the outer countersink wall, the chuck wall including a kick portion having a curved shape beginning at a point lower than a lowest point of the inclined panel wall;
- and
- a curl extending radially outwardly from the chuck wall.
Tooling for forming a can shell, the tooling comprising:
- an upper tool assembly;
- and
- a lower tool assembly,
- said upper tool assembly and said lower tool assembly are structured to cooperate and to form a can shell, said can shell including a center panel, an inclined panel wall extending at a downward angle from the center panel, an annular countersink formed around the inclined panel wall, the annular countersink including an inner countersink wall and an outer countersink wall, a chuck wall extending from the outer countersink wall, the chuck wall including a kick portion having a curved shape beginning at a point lower than a lowest point of the inclined panel wall, and a curl extending radially outwardly from the chuck wall.
A method of forming a can shell, the method comprising:
- providing a blank;
- providing a tooling with an upper tool assembly and a lower tool assembly;
- introducing the blank between the upper tool assembly and the lower tool assembly;
- forming the blank to include a center panel, an inclined panel wall extending at a downward angle from the center panel, an annular countersink formed around the inclined panel wall, the annular countersink including an inner countersink wall and an outer countersink wall, a chuck wall extending from the outer countersink wall, the chuck wall including a kick portion having a curved shape beginning at a point lower than a lowest point of the inclined panel wall, and a curl extending radially outwardly from the chuck wall.
