Dual Spout Mouthwash Packaging Activates Solution when Mixed
Triumph Pharmaceuticals’ SmartMouth Mouthwash provides 12-hour protection from bad breath by attacking the real source: sulfur gas that’s created when bacteria in your mouth react with protein molecules in saliva and food.
SmartMouth’s formula comes from two different solutions that release odor-neutralizing zinc ions when mixed. Originally, this meant selling the product in two separate bottles with pumps and a cup, requiring the consumer to pump three times from each bottle. Consumers loved the mouthwash, but hated the pumps of the retail packaging design. That's when Nottingham Spirk stepped in tosolve the packaging problemand make a consumer-friendly dual-spout bottlethat mixed two separate mouthwash solutions on contact.
Designing a dual-spout bottle presented our team with unique engineering challenges. For example, the two solutions flow at different rates, but a dose must contain equal amounts of both for proper activation. The bottle had to pour accurately from any angle and prevent accidental mixing of the solutions inside when tilted upright again. Its retail footprint could not exceed that of the original two-bottle package, and the consumer product packaging had to resemble the familiar packaging as closely as possible.
Through extensive prototyping and consumer testing, weengineered a bottle that eliminates all the pain points. Multiple patents are pending on the new bottle, which is now available in stores everywhere.
The redesigned SmartMouth bottle has been recognized for retailpackaging design excellence, receiving accolades from the PAC Packaging Competition, and “Best of Show” at the Annual NACD Packaging Awards.
