|A cone is shown below. This is a shape occasionally used as packaging.|
|Opposite is the
development of a cone. The flat development is part of a circle and a tab
is added on the leading edge so that it can be glued to form the cone
shape. Can you name any products that have this type of development for a
Make the cone development.
|The cone development is a less efficient shape to store in a cardboard box, compared to the square pyramid. Some space is left unused when the cones are stacked in a standard cardboard box . The cones fit head to tail creating a reasonably strong structure. However, the spaces that are left mean that the cardboard box can be damaged if dropped or knocked. Greater care is needed when handling a box with this type of packaging inside.|
|When being transported
in a lorry or transit van the ‘cuboid’ cardboard boxes can be stacked and
handled easily. The cuboid boxes can be arranged in the lorry / van so
that very little space is left.
The diagram opposite shows how the boxes could be arranged efficiently. This means that many of the individual cone packages, possibly thousands, could be transported in one journey. Despite some space left in each cardboard box, this would lower delivery costs, compared to many other packaging designs.
