Flat Bottle Caps Are a Product-Design Improvement of the Decade18 Jan 2010
One of my favorite product-design improvements of the last decade comes from the widespread adoption of flat caps on bottles of shampoo, face wash and other liquid toiletries. To be able to use all the contents of a bottle, we up-end them to let their contents drain down towards the cap. Thick liquids like shampoo take time to drain, so we leave shampoo bottles upside down until we finish their contents. We have to hack solutions to rounded bottle caps, such as balancing up-ended bottles against the bathroom wall or storing up-ended bottles in a glass. Manufacturers have realized that their bottles spend at least part of their life upside down. Designing a product for all the ways users interact with it always makes life easier, which is the purpose of good design.
