You will be awarded marks for:
An imaginative and creative design.
Explanation of manufacturing techniques involved.
Adding an image/images, to encourage healthy eating.
This is my basic design for a new packed lunch box. I have chosen a
recognisable shape. It does not have sharp edges and will be easy to carry
under arm. It will also fit into a typical school bag.
The box will be manufactured from polypropylene as this comes in a range of colours and it can be recycled.
|I have added an image of a heart, with a simple pair of eyes. The pupils of the eyes can move.|
I have developed a ‘cartoon’ heart from a simple shape and included large
The yellow eyes contrast the red heart.
I have added a divide inside the packed lunch box, to keep foods separate.
An ergonomically designed handle has been added, to ensure that the box can be carried easily.
The cartoon character has been placed on the lid, along with the slogan ‘Eat Healthy’. This will remind parents to put only healthy food in the container.
My final design can be seen opposite. It will be manufactured in a range
The image will be printed on the lid through a technique called screen printing. This technique is used to print colour onto music CDs and works just as well on polyethylene.
Alternatively, lithographic printing on polypropylene, PVC, PETG and vinyl and Mirri Board, could be used.
The lid has a push fit with the main casing
|BLOW MOULDING MACHINE|
1. Granules of polypropylene are added to the hopper.
2. The granules fall on to the archimedean screw which pushes them through the heater.
3. The granules melt and become mouldable.
4. As the molten polypropylene is forced into the mould, a ‘jet’ of compressed air forces it to the outside wall of the mould, forming the body of the container.
5. When the polypropylene cools, it can be removed from the mould.
