Caps and closures developments: Difference between revisions

­

'''It was a Swiss designer named Albert Obrist who in 1970 developed the first plastic top for CSD drinks bottles with the injection-moulded onepiece HDPE cap. Originally intended for use with returnable glass bottles, his idea quickly attracted the interest of the PET bottle industry which increased sharply at the end of the 1970s. The key advantages of the HDPE cap over its aluminium counterpart were considered to be, firstly that damage to the bottle mouth caused by rolling the aluminium caps onto the neck finish could be avoided, and secondly that the HDPE caps were more compatible with the precise geometries of the PET thread. Obrist’s innovations were subsequently incorporated into the Crown Cork and Seal Company’s operations during the mid-1980s.'''

Romeo [[Corvaglia]] reported in issue in 2+3, that the 0.99 g cap for still water was on the market in North America. Issue 9 reported that Coca-Cola China had decided to universally adopt the PCO 1881 by the end of 2009.

In issue 4 we report on the launch of a push-pull closure for hot fill packages without aluminium foil, developed by [[Bericap]] in 2010.

We report in issue 1+2 on [[Bericap]]’s Neo 30/17 weight optimised version for the neck finish 30/25; the SnapCap 26: a hinge cap pressed on a lightweight 26/21 neck and the 33 mm neck closure for cold-aseptic or hot-filling recipes.

Continuous growth of aseptically processed beverages and an increase of on-the-go beverage formats are reasons for [[Aptar]] to launch a new sportscap in a wide mouth neck finish. The 38 mm 1-piece closure is described in issue 5.

For issue 10 we fly downunder, visiting Coca-Cola Amatil’s plant opening of their new sports cap production line. Being made entirely of HDPE, it is easier to recycle than the traditional mix of HDPE and PP.
