PURPOSE:To provide a sealing cap capable of being closed by a strong tightening force, excellent in barrier property and printable decoratively. CONSTITUTION:The sealing cap 1 comprises a metal member 2 having a vertical part 23 downwardly extending from the outer peripheral edge of the top face 21 of the cap and a synthetic resin member 3 attached integrally with the metal member 2 so as to enclose the periphery of the top face 21 of the cap and the vertical part 23 of the metal member between the inner and outer coverings of the synthetic resin member 3. The synthetic resin member 3 is provided with an inwardly projecting part 31 on the inner resin covering above the lower end of the vertical part 23 for engagement with an outwardly projecting part 41a of the neck part 41 of a bottle 4. The metal member 2 provides a barrier property and the top face of the cap can be printed. The vertical part 23 of the metal member 2 makes the side wall of the cap highly rigid and, therefore, the bottle 4 can be capped by a strong tightening force. |
