A fluid sample device comprising at least two superposed sheets (1, 2) that are connected together by a retaining element (3), each of the sheets including an inside face (1a, 2a), the inside faces (1a, 2a) facing each other in such a manner as to come into contact, the inside face (1a) of at least
A fluid sample device comprising at least two superposed sheets (1, 2) that are connected together by a retaining element (3), each of the sheets including an inside face (1a, 2a), the inside faces (1a, 2a) facing each other in such a manner as to come into contact, the inside face (1a) of at least one sheet (1) including a zone (4) that is provided with microcapsules (4, 4′) containing a fluid, the sample device being characterized in that the inside faces (1a, 2a) slide relative to each other with friction between a masked position and an exposed position of the zone (4) of microcapsules, being connected by the retaining element (3), in such a manner as to break the microcapsules and release the fluid contained therein progressively.

1. A fluid sample device comprising: a retaining element; andat least two superposed sheets connected together by the retaining element, each of the sheets including an inside face, the inside faces facing each other in such a manner as to come into contact, the inside face of at least one sheet including a zone that is provided with microcapsules containing a fluid;wherein the inside faces, while the at least two superposed sheets remain connected together by the retaining element, slide relative to each other with friction between a masked position and an exposed position of the zone of microcapsules in such a manner as to break the microcapsules and release the fluid contained therein progressively. 2. A sample device according to claim 1, in which said faces slide by pivoting about the retaining element. 3. A sample device according to claim 1, in which the sheets (1, 2) are movable, by sliding with friction, from an exposed position to a masked position, while being connected together at all times by the retaining element (3). 4. A sample device according to claim 3, including return means for returning the zone to its masked position. 5. A sample device according to claim 1, including a plurality of zones (4) of microcapsules. 6. A sample device according to claim 5, in which a plurality of zones (4) of microcapsules are disposed on a disk-shaped sheet (1) with the retaining element (3) being disposed centrally, the zone-free sheet (2) including a window (8) in which the zones (4) can be positioned by turning the two sheets relative to each other. 7. A sample device according to claim 1, in which at least one of the sheets (1; 2) includes a grip notch (5) for taking hold of the other sheet that does not have a notch. 8. A sample device according to claim 1, further including a holding element (7) for holding the superposed sheets in the masked position. 9. A sample device according to claim 1, in which the sheet (1) provided with zones (4, 4′) of microcapsules is disposed between two sheets (2) forming a sleeve (2′), the two sheets being connected together via at least one edge (22) and advantageously by the retaining element (3). 10. A sample device according to claim 1, in which the inside face (2a) of the sheet (2) that rubs against the zone (4) of microcapsules presents a surface quality that is rough or abrasive. 11. A sample device according to claim 10, in which abrasion is greater in the direction going from the masked position towards the exposed position than in the opposite direction. 12. A supporting medium comprising pages, such as a magazine, a prospectus, or an envelope, said supporting medium including a fluid sample device according to claim 1, inserted between its pages. 13. A supporting medium according to claim 12, in which the sample device is fastened in removable manner to the supporting medium by means of at least one of the sheets, so as to enable the sample device to be carried or re-used separately from the supporting medium. 14. A fluid sample device comprising: a retaining element; andfirst and second superposed sheets pivotally connected together by the retaining element, an inside face of the first sheet facing and contacting an inside face of the second sheet;the inside face of the first sheet comprising a zone comprising microcapsules comprising a fluid;the first sheet and the second sheet pivotally retained to allow the inside face of the second sheet to relatively slide with friction against the inside face of the first sheet between a masked position of the zone and an exposed position of the zone, the friction resulting in breakage of the microcapsules;the first sheet and the second sheet remain pivotally connected together by the retaining element during the sliding of the inside face of the second sheet relative to the inside face of the first sheet.
