trident xtra care is a chewing sugar-free gum that helps protect teeth and gums in between meals and gives a whiter brighter smile. in order to visually enhance this main feature of the product, hani douaji has created a playful and interactive packaging concept. a range of six designs represents three flavors: cool mint, spearmint, and peppermint. each container has its own masculine and feminine identity featuring an illustration of a mouth with either a thick, dark mustache or luscious red lips. these shapes provide an opening that reveals the pieces as a set of smiling teeth. furthering the personification, the aluminum housing is colored in pink to mimic the gums of a person’s mouth. therefore, the clever use of negative space to an advantage changes the appearance of the creations over time while indicating when it’s time to purchase a new pack.
