The Galileo II closure is a two-piece, flip-top closure weighing 3 g. The base, which is the sealing element between bottle and closure, is made of Polyethylene, while the over-cap is made of transparent Polypropylene. Thus, color combinations are possible, giving the bottle a modern and contemporary look, due partly to the transparency of the over-cap. The closure adds value to the package, providing for product differentiation on the shelves.
Incorporated to the closure are two independent tamper-evidence seals. The consumer needs to first break the over-cap seal before being able to remove the pull-up ring, which eventually breaks the second seal. This second seal opens four small holes which act as flow regulators. The vinegar can thus freely be dosed, either by droplets, sprinkles or even be "showered" over the salad, depending on how much the consumer presses onto the bottle.
The challenge for BERICAP was on one hand to create the second seal formed by the four independent membranes to be tight to hold internal pressure created by Nitrogen dropping; and on the other hand to easily break once lifting the pull-ring. Due to the recent trend of ever increasing PET resin costs, BERICAP conceptualized a new and lighter neck finish. Potential PET resin savings are substantial, translating into a more economic package. Aiming at innovation, consumer convenience, and appeal as well as cost reduction, the Brazilian Vinegar market leader Alimentos Castelo adopted the Galileo II closure to enhance the contemporary look of its new bottle.
