• Document US-A-3 998 559 describes an applicator device the reservoir of which comprises, in its center, rigid internal walls which converge towards a cutting apex located near a thin and frangible base sheet, said base sheet being hermetically linked to the rigid walls of the tank.
• a sponge is fixed to the external face of said base sheet, so that a pressure on the rigid walls of the tank causes the rupture of the base sheet by the cutting top, to allow the diffusion of the liquid from the tank in the sponge.
• the tank is separated in two by the internal walls which converge downwards, and the walls of the tank must be made of rigid material, which makes it difficult to compress the tank, in order to deform it.
• the subject of the invention is a device for diffusing one or more doses of fluid product, each dose being contained in a sealed reserve which is defined between two films of plastic, metallic, composite or other material, integrally and hermetically linked , through example by gluing or heat sealing, to each other in a peripheral bonding zone, the first film being intended to undergo a crushing pressure on the part of the user, and the second film being thin and frangible to allow to the fluid product to diffuse outside the reserve when said second film is pierced, torn or fractured, under the effect of said crushing pressure exerted by the user on the first film, characterized in that said first film is made of flexible deformable material to allow its hollow deformation under the crushing pressure exerted by the user, and that a stress concentration means, separate from said first film, is locally associated with said reserve, to cause rupture of
• the aforementioned first film comprises a central region that is curved outwards, obtained for example by molding of plastic material, and a substantially planar peripheral region defining a peripheral surface for supporting and gripping the device, while the second film, for preferably made of metal, has an essentially planar shape covering the entire central region and at least partially the inner peripheral region of the first film, the two films being permanently heat-sealed to each other in the plane peripheral zone of overlap two films.
• the first film is heat-sealed to the second film on a peripheral bonding zone, the internal contour of which has at least one profile suitable for generating a rupture initiation of said second film in line with said profile, when a overpressure is generated in the reserve, under the effect of the aforementioned crushing pressure, said profile of the internal contour of the final heat seal, constituting the aforementioned stress concentration means.
• said profile can be in the form of a point facing the interior of the reserve.
• said profile has at least one point of inflection on a plane curve defining the internal contour of said peripheral connection zone.
• the stress concentration means comprises at least one part provided with at least one point for piercing said second film.
• said part can be housed mobile inside the reserve, between the two aforementioned films, with the points facing the second film.
• said part is housed outside the reserve, with the points facing the second film.
• the device comprises a layer of material forming an applicator pad, capable of being impregnated with the fluid product, when the reserve is opened, by means of the stress concentration means.
• the device may include a free space between the interior surface of the applicator pad and the second facing film to allow the product released by the reserve to be distributed evenly over the entire surface. buffer.
• an absorbent backing paper carrying an adhesive temporary tattoo ink is positioned on the external face of the pad, so that moistening the pad and then the backing paper causes the instant transfer of the tattoo on all chosen surfaces.
• the support paper is hermetically bonded, for example by gluing, over its entire periphery, to a peripheral region of the first film.
• the device comprises a peelable protective film capable of covering the external face of the aforementioned pad, or of support paper carrying the adhesive temporary tattoo ink.
• the device comprises an additional film linked to the periphery of the first film, on the side opposite to the second film, to define a volume of air between the additional film and the reserve.

• the adhesive temporary tattoo application device comprises a first film 1, for example made of transparent plastic, and a second film 2, consisting for example of a thin aluminum film, defining between them a reserve 3 intended to contain a product. fluid.
• the first film 1 is of substantially square shape and has a planar peripheral region 4 intended to serve as a support and gripping surface of the device.
• This planar peripheral region 4 is extended, at its center, by a cylindrical recess which is connected by a planar annular surface 5, to a cylindrical wall 6, the bottom of which is closed by a spherical cap 7.
• the spherical cap 7 is suitable for deform hollow, under the action of an external crushing pressure, to generate an overpressure in the reserve 3.
• the second film 2 is in the form of a circular disc which is housed in the cylindrical recess of the first film 1 and bears on the flat annular surface 5.
• a sponge applicator pad 10 is interposed between the absorbent support paper 8 and the second film 2 inside the cylindrical recess of the first film. As visible in FIG. 3, an intermediate space is provided between the lower face of the second film 2 and the upper face of the applicator pad 10.
• the absorbent support paper 8 carries on its lower face a layer of ink 12 for temporary tattooing adhesive.
• a transparent protective plastic film 13 is glued, along an edge 14 on the underside of the backing paper 8, to isolate the adhesive decal ink 12 from any external element which may damage it. This protective film 13 can also be provided slightly self-adhesive and peelable, to facilitate its removal, before using the device.
• the device further comprises a third plastic film 15 which has a planar peripheral region 16 capable of being superimposed on the planar peripheral region 4 of the first film 1.
• This planar peripheral region 16 is extended at its center by a cylindrical wall 17, the bottom of which is closed by a spherical cap 18.
