The practical advantage of being able to see through containers is very evident in the packaging, retail, and the domestic storage of food. See through packaging enables comparison between products whilst protecting the contents from spoilage, whilst transparent containers enable levels to be monitored and replenished in good time.
Many traditional glass containers have been replaced by lightweight plastic alternatives. The milk bottle (1) and honey jar (2) are made from polyethylene, and the hand wash bottle (3) is made from transparent polyethylene terephthalate (PET). The capability of plastics materials to be moulded into any shape enables their use to enhance the marketing of a product. The water bottle (4), produced to commemorate the 10th anniversary of the More Water project, comprises a colourless PET bottle topped with a translucent water mimicking splash. Innovations in plastic packaging design exploit the material to reference more traditional packaging. The two bottles for Garçon Wines (5 - 6) retain the look of glass bottles combined with a design and strength of material which enable it to be sent through the post.
The rise in popularity and affordability of the domestic refrigerator in the mid-20th century generated the desire for practical, stylish and safe methods of storing food. The set of boxes (7 - 9) was designed specifically for use in Electrolux refrigerators. Made from transparent styrene acrylonitrile (SAN), they are tough and resistant to grease and stains. The stackable polystyrene food boxes (10 - 11) make the best use of limited space. Tupperware containers (12), keep food fresh for longer by sealing out expelled air. The translucent polyethylene bowls allowed the contents to be seen without having to open the lids.
Transparent and translucent plastics in domestic appliances are of benefit, allowing the user to see when something needs to be refilled or emptied to maintain optimum function. The steam iron (13) and cordless kettle (14) have translucent water chambers whilst the transparent polycarbonate dust bin of the Dyson vacuum cleaner (15) clearly shows when it needs emptying to maintain performance.
