Abstract
The invention concerns an applicator device comprising a storage means for storing a product to be applied, and an increased pressure-producing device having an elastic device, wherein the elastic device is designed to press with its elastic return force against a boundary means of the storage means, to produce an increased pressure in the storage means. In accordance with the present invention it is provided that the increased pressure-producing device is controllable to provide a reduction in the pressure in the storage means.
Claims24
An applicator device comprising
- a storage means for storing a product to be applied, an increased pressure-producing device having an elastic device, wherein the elastic device is designed to press with its elastic return force against a boundary means of the storage means, to produce an increased pressure in the storage means, the increased pressure-producing device is controllable to provide a reduction in the pressure in the storage means and comprises a transmission arrangement comprising a first element and a second element, wherein the transmission arrangement can assume at least two operative states, namely
- (1) a first operative state in which the elements engage with each other to produce the increased pressure, and
- (2) a second operative state in which the elements do not mesh with each other, thereby resulting in a fall in the pressure.
