We were tasked with designing an innovative lunch box for children that solves the problems of existing products. Its new type of gasket prevents spillage from the compartments, allowing parents to pack food in liquid form, such as yogurt, ketchup and salad cream. Other lunch boxes on the market that claim to seal their compartments suffer from mould growth, gaskets getting stuck in the compartments and spillage through gaps in the gasket.

Another new feature is a handle that prevents the box from opening and the food falling on the floor (or the child!) if they forget to fasten the latches. When the handle is unfolded for use, it snaps onto the base, preventing the cover and base from separating when the box is lifted. The internal trays, including a removable microwave tray and gasket, can be washed individually so the whole lunch box doesn't have to be washed.

SourcePro developed the product from the very first concept through to organising its manufacture: concept ideas, CAD development and rendering, a first 3D printed prototype, a machined prototype for testing, gasket efficiency tests and design for injection moulded plastics.
