Conversion PCO 1810 - PCO 1881

The German company CCT (Creative Closure Technology GmbH) designed the ComPetCap CC 28/21-01 especially for carbonated beverage packaging. This is a neck and closure version, called "PCO 1881 med", which ideally combines the material-saving neck and closure version PCO 1881 with the quality of consumer-friendly neck and closure version PCO 28 (1810) being used by the market for decades. The closure is 21 mm tall and only weighs 3.9 g, resulting in a saving of at least 1.5 g for pre-form and closure in comparison with the neck and closure version PCO 28 (1810). As the ComPetCap doesn't require reconstruction costs on moulding, filling and capping, it makes it the lightweight alternative for owners of older bottling plants, as they can often only convert from PCO 1810 to PCO 1880 at high cost.

Is this the end of the evolution in shorter caps. I doubt it. I am sure, the development of bottle closures continues in the direction of more savings in raw material. Time will tell.
