Today’s invention is an aid to those of us who need to lose some weight.
It consists of a fridge door handle which is held shut by a spring mechanism. pumping the handle for a certain number of times, against the spring resistance, is required to allow the door to open and the food inside to be accessed.
This principle might be extended to a number of separate compartments within a fridge or cupboard, each with a sprung-closed lid and an individual counter.
