Effective Simplicity

The Bottleneck Saver is a simple piece of rubber which slots onto the stem of a push-button dispenser bottle ... you know, the type used for liquid soap and hand cream.

A concept design from Orca Design's Greenhouse Effect exhibition, it's purpose is to stop the "push" part way, hence reducing the amount of product dispensed. Straightforward, but effective.
