‘More or Less’ pump / Pump liquid dispenser

The application quantity of a personal care product such as shampoo varies from person to person. However, pump head bottles only pump out a fixed amount of liquid except if the user manually tries to limit the amount. Often, however, too much of the bottle contents is dispensed, a nuisance and also wasteful. Our new type of care product pump head resolves this problem, allowing the user to control the output volume by a simple turn of the pump nozzle for either more or less of the liquid contents.
