The brief was to create a child-resistant but elderly-friendly powder dispensing closure.
Addressing the cognitive limitations of little ones and the reduced dexterity that many older people have presents as a very challenging brief!
This closure uses a two-step process that is too hard for small children to understand but is easy enough for elderly or arthritic fingers to carry out without confusion or frustration.
Ergonomics was used as a directive of the form to help the user to intuitively interpret how to use the cap.
The cap is made up of two parts and uses two living hinges to impart multi-use options for the user.
Understanding principles in injection molding and ergonomics lead to the creation of a unique, innovative design outcome.
