BOTTLE MAKING 28 PET planet insider Vol. 17 No. 09/16 www.petpla.net Liaison of PET and PP for keeping liquids separated View the elements TricorBraun earned a Silver Award in the 28 th DuPont Awards for Packaging Innovation for their novel and user-friendly packaging for Prestone Stop Leak. The packaging format contains three separate component parts combined into one to provide a simple and efficient use for car repairs. The liquid portion is contained by a 3oz PP bottle which sits in an 18oz clear PET bottle. The overcap does double duty as a jar holding the pellets portion of the product and is closed with a 51mm pinch and turn CRC closure. The stand out feature is the design aspect that keeps the liquid for- mula and pellets separate until use. Prestone Products Corporation’s patent-pending Triple Seal Protec- tion Stop Leak family of products are intended to help eliminate expensive consumer auto repairs to radiators, head gaskets and engine blocks. To effectively deliver the value and ease- of-use of this complex product and simplify the consumer experience, TricorBraun partnered with Prestone to develop a functional, transparent, three-compartment intuitive pack- age design. This design allows the consumer to clearly see all of the ele- ments of the product and engage with the product in a way that provides a more positive user experience. The product’s three active ingredi- ents are beads and two liquid chemi- cals. The packaging brief called for a unified design that communicated to the consumer an “all-in-one system” while also providing storage for each of the ingredients in separate dosing chambers. First, the consumer adds the effervescent beads found in the top dosing chamber. Second, the con- sumer simultaneously pours the two separated liquid components from the inner preform tube and exterior bottle into the designated problem area. The resulting mixture seeks and finds the location of the leak and creates a web of fibres that bind to the metal around the leak while an acrylic poly- mer hardens and secures the seal. In spite of the fact that the Triple Seal Protection’s three ingredients must be stored separately, Prestone wanted them packaged as one convenient, transparent unit to enhance the con- sumer’s engagement with the new product. “We knew from the beginning how we wanted the packaging to look and work,” says Thomas Kalagher, Marketing Product Manager, Prestone Performance Chemicals. According to TricorBraun VP of Engineering & Technical Ser- vices, Jon-Paul Genest, “Prestone approached us with a complex and unproven design and what seemed like an impossible launch date. Our project management team responded with an actionable and manage- able timeline and clearly defined deliverables. We maintained close collaboration and managed expecta- tions throughout the process. From there, we engaged with one of our trusted development partners, Currier. Optimising our path to success was critical every step of the way.” Mas- simo Leone, VP Business Develop- ment, Currier Plastics describes what happened this way, “Working as a team with TricorBraun, we collectively managed to successfully finalise three different materials and four separate components with two different tech- nologies. Both the injection moulding and injection stretch blow moulding process disciplines were needed. Also, three prototype injection moulds were launched concurrently with the injection stretch blow mould produc- tion tool. Timing was absolutely critical as the product was required to launch within three months from start to finish. Without the combined efforts of our mutual team, the aggressive launch date would never have been met.” Developing the package Kalagher’s concept for the pack- age was a clear bottle with a smaller inner tube and a dosing chamber on top that houses the beads.
