INNOVATION | CAPS AND CLOSURES

considerably, which in turn saves time on the road. In addition, Bericap has developed two weight-optimised closures that can be used both for AdBlue and for commercially available car care products. Bericap offers various shapes and sizes of expandable pourer types, which provide significant pouring assistance to the consumer, for example, when bridging a necessary distance for spill free pouring. They can be used for container sizes from 5-25 l. The foldable pourers are designed for easy push-in application into containers. They fit onto containers with standard neck sizes DIN42 and DIN45 due to their conical foot design – they are simply pressed into the container neck and start pouring leak-free. For accurate pouring results the long expandable nozzle is bendable 180 degrees and will remain in this position without additional fixing by hand. This feature allows the consumer to hold the container with both hands for safe pouring. The flow is fast and steady without leakage. The pourers are available with and without shrink foil, which can protect against dust when necessary. The Bericap foldable pourers are already used by notable customers from the automotive, mineral oil and chemical industry. Berry Bramlage, part of Berry Global, has also developed a tethered closure design that meets the EU requirements. The company says that it has developed a series of designs for all types of neck finishes, including both screw and snap-on. The solutions involve additional strands or tabs on the tamper-evident band that keep the closure attached after opening and enable easy reclosing of the bottle. In order to maximise consumer convenience and ease of use, different options for the docking of the closure once the bottle has been opened are

available to meet different product or pack requirements. These include placing the closure beneath the neck (the Lasso and V-Tethered closures) or adjacent to it at a wide angle (Compact Flip and Proxima closures). The


two-piece SecureSnap closure for snap-on necks is based on the flip top design of Berry


Bramlage’s Secure Flip sports cap, with its opening tamper-evident band that is retained on the closure after opening. All closures can be specified in a variety of colours with a choice of decoration options for enhanced branding and on-shelf appeal. Closure Systems International (CSI) has


introduced the 38mm D-KL liner-less HDPE closure (38D-KL), which is designed with consumers and dairy product applications in mind. With improved application performance and drop-down tamper evidence for additional security, the company says that the 38D-KL is engineered to deliver reliable performance on HDPE and PET dairy bottles. The 38D-KL is commercially available for applications in non-carbonated cold- and ambient-filled bever- ages and liquid dairy markets. CSI adds that the 38D-KL closure offers a sustainable solution and can be sourced with up to 40% PolyCycle PCR HDPE resin. PolyCycle PCR is sourced from recycled milk and other beverage containers, providing an opportunity for closed loop packaging and ensuring the high quality sourcing. Both the HDPE and the PolyCycle PCR version of the 38D-KL closure are 100% recyclable. Engel has introduced the next generation of the all-electric E-cap injection moulding machine series for beverage caps. The company says that production of 29/25 lightweight caps on a new E-cap 380 machine combines short cycle times with high precision and low energy consumption. Up to its launch at K2010, hydraulic machines using accumulators for the injection movement were the standard for the production of caps. However, Engel claims that the E-cap is the most energy-efficient cap machine on the market and at the same time the only high-performance machine tailored to the requirements of the caps and closures industry providing all-electric operation even with a clamping force range as high as 4,200 kN. It has an average return on investment of less than two years, says the company. “Since 2010, the requirements for beverage caps have changed substantially,” says Friedrich Mairhofer, Product Manager for all-electric injec-
