'Squezy' bottle, 1958.
© Science Museum / Science & Society Picture Library
Manufactured by Domestos (BXL Cascelloid Division) and made of Cascelloid, this was the first 'squeeze-to-use' detergent container. The bottle has two metal ends. Cascelloid is one of the trade names used for the plastic polyethylene. As well as being cheap and quick to mould, plastic bottles are flexible. This was made a selling point by early advertisers, a way to get the product out of the bottle quickly.
