Tamper-proof cap for bottles

Abstract

A tamper-proof cap for bottles comprising a cylindrical single piece injected in plastic material, including a cylindrical vertical base and a circular sealing belt connected to the cylindrical vertical base lower end, including a plurality of equidistantly spaced articulated blades adjacent to the lower presenting at least one anti-attrition flange radially inwards projected and a base, the flanges enabling a special effect in each blade during the process of application of the caps by high-speed machines. Specifically, the coupling of the cap occurs with low attrition because the contact area between the blades and the neck or collar of the neck is limited only to the flange. The cap is also designed to prevent the simultaneous unscrewing of the cap and of the sealing means, preventing the breakable elements from deforming instead of disrupting.

1 . A tamper-proof cap for bottles, said cap comprising: 
 a cylindrical single piece injected in plastic material, including: 
 a cylindrical vertical base, including a lower external even surface, an upper external anti-sliding surface and an internal surface with an internal adequate thread, a superior end completely closed by a circular wall with a round shape edge, a respective sealing layer placed against the circular wall and a lower end presenting an increasing internal diameter, which is designed extending from the diameter of the internal surface; and  
 a circular sealing belt connected to the cylindrical vertical base lower end, including: 
 a wall,  
 an internal surface;  
 an external surface;  
 an upper end;  
 a lower end;  
 a circular cut line above said thickening, said cut line interrupted by breakable elements; and  
 a plurality of articulated blades adjacent to the lower end, said blades equidistantly spaced, configured with a dimensional detail operating as a locking component between the cap and the bottle;  
 wherein the articulated blades present at least one anti-attrition flange radially inwards projected.  
 
   
   
   
       2 . The tamper-proof cap for bottles according to  claim 1 , wherein the articulated blades present two or more flanges, each flange distributed equidistantly along a central axis.  
   
   
       3 . The tamper-proof cap for bottles according to  claim 1 , wherein the internal adequate thread is interrupted by sections.  
   
   
       4 . The tamper-proof cap for bottles according to  claim 1 , wherein the sealing belt presents a definite outwards increase on the its wall thickness.  
   
   
       5 . The tamper-proof cap for bottles according to  claim 1 , wherein the anti-sliding surface presents grooves.
