<p>The device has two superimposed sheets (1, 2) connected together by a retaining element (3) e.g. paper type retaining element, where one sheet (1) is in form of a disk. The sheets have internal surfaces (1a, 2a) turned one towards another to come in contact with each other. The surface (1a) has a microcapsule zone (4) with microcapsules containing a fluid product. The surfaces slide between them with the friction between masked and exposed positions of the zone while being connected by the element to break the microcapsules and to progressively release the product contained in the microcapsules.</p> |
