ered need. The company says that they are compatible with all of the most popular neck finishes and have slight variations in terms of how shell locking is achieved based on neck specific requirements, for example, small versus large support ledge (SL) diameters. All of the designs feature the same performance criteria as the non-tethered alternative. Examples of new designs include the 1881
Large Diameter Support Ledge. This is for large SL diameters (33mm), with a closure locking feature that leverages the support ledge to assist in the shell locking position. The 1881 Small Diameter Support Ledge is for small SL diam- eters (31mm) and has a closure locking feature that leverages a hook defined on the shell in cooperation with a flap defined in the tamper evident band to achieve a positive locking position. There is also a re-closing feature that employs an

integrated cam to promote an intuitive, repeatable and smooth re-closing experience. Husky adds that it is working with a variety of recognisable global brands to offer solutions that incorporate these features to satisfy their specific product needs. There are also a number of future opportunities
Right: Bericap has developed a new tethered cap
that the company sees for caps and closures. “There are a number of priorities that Husky is focusing on in terms of development,” White says. “Improvements will be focused primarily in a number of key areas. In terms of sustainability, there will be continued efforts around tethering, lightweighting and increasing the post-consumer resin (PCR) content to ensure that Husky’s closure offerings offer the best environmental footprint possible. In performance, Husky’s closure develop- ments will continue to offer elevated performance levels without compromising safety, sustainability or user experience. There is also a need for enhanced safety. The global coronavirus pandemic has emphasised the impor- tance of supplying a dispensing system that offers a hygienic drinking solution for the consumer. We will continue to seek alternative options to make tamper evidence more visible without adding weight or compro- mising performance. Finally, for shelf differentiation and usability, we will continue to develop designs that offer brands a means to further differentiate themselves on

the shelf and incorporate features that enhance the consumer experience.” Caps moulders have also been responding to
the EU’s Single Use Plastics Directive’s requirement for closures to remain tethered to the bottle during consumption. For their customers in the beverage industry, the new closures must not affect the cost of production, bottle design, bottle neck, filling line or the capper. In addition, the closures should be available both as lightweight press-on caps, which are mainly used in non-pressurised bottles such as still water, and as screw-on caps for higher de- mands on the tightness of the closure. Bericap has achieved this through a redesign of
existing closures. “Within the product development process, it quickly became clear that the screw caps had to be redesigned no matter which technical solution is proposed,” says Volker Spiesmacher, Director Head of Product Sales and Marketing. “The tether requires more space in the area of the tamper evidence band. Hence, the screw caps had to be redesigned.” The four technical proposals for screw caps now
presented by Bericap can be applied to the same closure shell which is a redesign of the current closure. All proposals can be applied to all major neck finishes available on the market. However, some proposals perform better, if small details of the neck are modified. The Bericap proposals allow for a market introduction of the new closure design suitable for tethered caps at an earlier stage. Therefore, the redesigned caps can be readily manufactured with all technical pre-requisites for a tethered version set in place when they become mandatory in 2024. The redesigned caps can then be introduced at a time that is in line with custom- ers’ marketing activities. In addition to the screw- cap solutions, Bericap also offers press-on caps for standard necks as well as a premium solution with customised neck finish which offers the highest weight savings on neck and closure.
Bericap has also developed a filling aid
for AdBlue tanks in diesel cars. It allows car owners to fill their AdBlue containers easier and faster, and helps to comply with current emissions standards. Since 2015, all first-registered Euro 6 diesel vehicles have had to use the AdBlue additive to reduce
nitrogen oxide emissions.
The filling aid from Bericap simplifies the handling of common 10 l refuelling tanks
