Threaded neck for a bottle

Abstract

The present invention relates to a bottle neck, comprising a peripheral wall and an aperture that is delimited inside a top edge of the peripheral wall. The bottle neck also includes at least one outer thread located around the peripheral wall, the outer thread having a top end, and an offset located under the top edge and lateraly extending from the peripheral wall to a border of the top edge. The bottle neck comprises at least one slope located along the offset and over the outer thread, and the at least one slop extends from the peripheral wall to the border of the top edge in an outward inclined way.

The invention claimed is: 
     
         1 . A bottle neck, comprising
 a peripheral wall and an aperture that is delimited inside a top edge of the peripheral wall;   at least one outer thread located around the peripheral wall, the outer thread having a top end; and   an offset, the offset is located under the top edge and laterally extends from the peripheral wall to a border of the top edge;   
       wherein
 the bottle neck comprises at least one slope located along the offset and over the at least one outer thread; and 
 the at least one slope extends from the peripheral wall to the border of the top edge in an outward inclined way. 
 
     
     
         2 . Bottle neck according to  claim 1 , wherein the top edge has a rounded shape. 
     
     
         3 . Bottle neck according to  claim 1 , wherein
 the at least one slope is located over the top end of the at least one outer thread;   the at least one slope extends in an outward inclined way according to an unscrewing direction of the at least one outer thread.   
     
     
         4 . Bottle neck according to  claim 3 , wherein the at least one slope comprises a blend located at a distal end, the blend radially links the distal end to the peripheral wall. 
     
     
         5 . Bottle neck according to  claim 3 , further comprising two slopes, where the slopes are distributed around the peripheral wall. 
     
     
         6 . Bottle neck according to  claim 5 , further comprising three slopes. 
     
     
         7 . Bottle neck according to  claim 1 , wherein the at least one slope is shaped as a chamfer and extends in an outward inclined way relative to a vertical direction. 
     
     
         8 . Bottle neck according to  claim 7 , further comprising one slope, the slope extends around all the angular length of the peripheral wall. 
     
     
         9 . Bottle neck according to  claim 7 , further comprising several slopes, the slopes are spaced apart from each other and are regularly distributed around the peripheral wall.
