Abstract (en)
[origin: JPH03111263A] PURPOSE: To guarantee sealing resistant to leakage and dropping without foil for sealing by providing a ring shape groove in the inside back part of a screw cap closure end face, by making the groove opening narrower than its width, and by placing an O-ring in the groove. CONSTITUTION: A screw-cap closure 2 is provided with a conical sealing ring 10 which presses the mouth rim 5 of a pouring spout 3 from inside in a sealed condition in an air tight condition. A ring shape groove 11 is positioned at the inside back of the screw-cap closure 2 end face 6 between the conical sealing ring 10 and the peripheral wall 7. The opening part 12 of the ring shape groove is narrower than its width, an elastic O-ring 13 is positioned in the ring shape groove 11, and the mouth rim 5 is tightly attached to the peripheral wall 7 in a closed condition. By this, air tightness with resistance to leakage and dropping and without foil for air tightness can be guaranteed.
