Abstract

Container of thermoplastic material having a body extending along a principal axis, characterized in that the body has at least one annular narrowed zone of extra thickness.

Claims

exact text as granted — not AI-modified
1 . Container of thermoplastic material having a body extending along a principal axis, characterized in that the body comprises alternating annular bulbous zones and annular narrowed zones of extra thickness, the overall diameter of which is less than that of the bulbous zones. 
     
     
         2 . Container according to  claim 1 , characterized in that the annular narrowed zone has a variable wall thickness. 
     
     
         3 . Container according to  claim 1 , characterized in that the bulbous zones have a concavity facing the interior of the container, while the narrowed zones have a concavity facing the exterior of the container. 
     
     
         4 . Container according to  claim 1 , characterized in that the narrowed zones have a wall thickness greater than that of the bulbous zones. 
     
     
         5 . Container according to  claim 1 , characterized in that the narrowed zones have an axial extension less than that of the bulbous zones. 
     
     
         6 . Container according to  claim 5 , characterized in that the ratio between the axial extension of the narrowed zones and the axial extension of the bulbous zones falls between 1 and 5. 
     
     
         7 . Container according to  claim 1 , characterized in that the bulbous zones have a substantially constant wall thickness. 
     
     
         8 . Container according to  claim 1 , characterized in that the narrowed zones locally have a wall thickness equal to or greater than twice the wall thickness of the bulbous zones. 
     
     
         9 . Container according to  claim 1 , characterized in that the narrowed zones have overall diameters that are substantially equal.
