There are two types of molds used to manufacture continuous thread closures: Unscrewing and Stripped. The differences occur in the molding process; when applied to a bottle finish, both function the same.
“Unscrewing” Closure Features:
• This closure has lugs around the bottom of the skirt
• Lugs enable the closure to be held in place while the “unscrewing” motion to release closures from the mold occurs
• Threads continue to the top inside of the closure
• Liners are glued into the closure because the threads go to the top inside
• Mainly used for small size closures
“Stripped” Closure Features:
• No lugs on this closure – it is popped off or “stripped” from the mold
• Threads end before the top inside of the closure creating a well area
• Liners are friction-fit inside because the well area and the threads hold in the liner
• Mainly used for larger size closures
