CLOSURES WITH JAWS


The strength of tradition
It is the model we have been producing for the longest time and for this reason the most tested. It consists of the classic three-piece scheme composed of two half-rings HUB and COVER.
 
 
 

TEETH CLOSURES


SPEED LOCK model
It represents the right compromise between economy and practicality. The simple rotation of the lid allows a quick opening and closing of the appliance.

 
 
 

BAND TYPECLOSURES


This is the state of the art applied to our quick opening closures. In this model, the opening and closing of the appliance are made possible by the presence of a flexible half-ring.
