Corvagliaâs new low-profile sports cap.
Injection molder Corvaglia Eschlikon, Switzerland) has been one of the first to make much hay with the new standards for short-neck closures, and says its 28 PCO 1881 short neck is making serious inroads in applications, especially carbonated soft drinks (CSD) and beer bottle closures, formerly using PCO 1810 caps. Now, says the company, it has expanded its offerings, placing into operation a new multicavity tool to mold three-piece push-pull sports caps for the 1881 neck-finish. Capacity is about 300 million caps/yr for the new short neck.
The short-neck closures offer significant resin savings, both for the closure but also for the blowmolded PET bottleâs neck. âFor a production quantity of 1 billion bottles, savings of about euro 3 million can be made in resin costs by using the short neck-finish,â says Thomas Anderegg, CEO of Corvaglia Closures Eschlikon AG.
