Cadbury has launched a new style of packaging aimed at helping people ration their favourite treats.
The confectionery giant has unveiled new, innovative 'twist and seal' wrappers that allow chocolate fans to have a bite of bars such as Dairy Milk, Wispa, Double Decker and Boost, and save the rest for later.
The move is being seen as a bid to help people cut down calories by resisting the urge to wolf down a bar in one sitting reports the Mirror.
