Abstract (en)
[origin: EP0290720A2] In a known plastic closure cap, its edge part is formed, as security ring, integrally with a screw cap via connection webs, the latter extending approximately radially in the transition from the outside circumference of the screw cap to the top circumference of the security ring. As a result of this radial arrangement of the connection webs, there is a risk that sharp tear-off ends of the connection webs remain on the outside circumference of the screw cap after it is unscrewed for the first time, which results in a risk of injury to the hands of the users of this closure cap. The risk of injury is to be ruled out completely by the new closure cap when it is unscrewed. In a closure cap with a tamper-proof security ring (3), which is constructed integrally with the screw cap (5) via connection webs (4), said connection webs (4) are sprayed onto the screw cap (5) in a lower position relative to the lower edge (15) of said screw cap. As a result, when the closure cap is unscrewed from a container for the first time, the tear-off ends of the connection webs (4) remain completely inside the lower edge (15) of the screw cap so that no tear-off ends projecting axially or radially over said lower edge result. <IMAGE>
