Verstegen two in one cap
Verstegen is a dutch company specialised in Spices & Sauces. There professorial dressing and sauces shared the same packaging and branding. Pouring some dressing or adding sauce to a dish are two vary different things (ask a chef), when pouring dressing you need some control and you want to pour in small amounts. When pouring sauce especially thick sauce you want a good constant flow and you need less control.
So Verstegen was looking fo a solution where they still could use the same packaging on both there dressings and sauces but with a new universal cap that was suitable for pouring dressings or sauces in the appropriate way independent of what is in the package.
The universal cap requirements where: support two types of pouring (for dressing and sauces), add some sort of Tamper-evident and the cap needs to have a matching design with there existing packaging.
