• the cap 2 can be attached and fixed to the body 1 in a removable manner.
• the body 1 forms at its internal wall near the edge 12 a latching groove 13 which here extends in the form of a flattened loop over the entire internal periphery. The function of this casing groove will be given below.
• the body 1 forms, at one of its faces, an actuating wall 10 which has an advantageously elastic deformability characteristic.
• the actuating wall 10 when the actuating wall 10 is pressed, the latter tends to deform by depressing, then to return to its original form of rest as soon as the pressure is released on it.
• the face 11 opposite the actuating wall 10 can be perfectly rigid and even provided with one or more reinforcement flange (s) 14 which define a stable support plane for the capsule 4, as will be seen below. after.
• the capsule 4 is initially sealed and defines a reservoir 40 containing fluid, fluid or powdery product.
• This capsule 4 is adapted to open at a predetermined location when a pressure is applied to its reservoir at an appropriate wall.
• the capsule 4 can be produced from a shell 41, for example thermoformed, and from an opercular sheet 46.
• the shell 41 defines a dome 42 and a substantially flat periphery 44.
• the opercular sheet 46 is fixed to the shell 41 at the substantially flat periphery 44.
• An internal volume or reservoir 40 is thus formed between the opercular sheet 46 and the shell 41 at its dome 42.
• the dome 42 is deformable or pushable when the it is supported on it, which has the effect of opening the sealed capsule at a predetermined location which differs in the various embodiments.
• the capsule 4 in all the embodiments, is arranged inside the body 1, bearing with its lower face, here constituted by the opercular sheet 46, on the support flanges 14 formed at the face 11 of the body 1.
• the capsule 4 is thus positioned so that its deformable dome 42 is located just below the actuating wall 10 of the body 1, so that a depression of the actuating wall 10 has the effect of deform the dome 42 of the capsule 4.
• the opening of the sealed capsule 4 is effected by means of a piercing needle 43, advantageously formed by the dome 42, which is oriented so as to come into contact and pierce the opercular film 46 when the dome 42 is deformed or depressed.
• the opercular film 46 thus constitutes a pierceable wall element through which the fluid stored in the reservoir 40 can flow once the piercing has been carried out.
• the capsule 4 forms a channel 47 which forms a part or which opens into the reservoir 40.
• This channel 47 is closed at its end by a weak weld 48 adapted to break apart. when sufficient pressure is applied to the deformable dome 42. An opening or outlet orifice is thus created to allow the fluid product stored in the reservoir 40 to flow out of the capsule 4.
• the applicator pad 3 comprises an application head 31 which defines at its external surface the applicator surface intended to come into contact with a target application surface such as the skin, the nails or even the hair.
• the application head 31, in all embodiments, is integral with the body 1. However, one can imagine embodiments in which the applicator pad 3 is integral with the cap 2.
• the apphcateur pad 3 is provided with a fixing plate 34 on which the application head 31 is fixed, for example by gluing or welding.
• This fixing plate 34 comprises an external peripheral edge 36 intended to come into engagement in the latching groove 13 formed inside the body 1.
• the latching of the edge 36 of the plate 34 provides a seal so that the fluid product coming from the capsule 4 cannot leak at the peripheral edge of the plate.
• the fixing plate 34 further comprises a window 35 which communicates the capsule 4 with the apphcation head 31 of the apphcator pad 3.
• the capsule 4 is fixed to the plate fixing 34 at the level of the window 35.
• the capsule 4 forms a fixing appendage 45, the edges of which are engaged inside the window 35.
• this appendage 45 forms the conduit 47 and the weak weld 48, while in the embodiment of FIGS. 1 to 3, this appendage 45 is formed only by the flat periphery 44 of the shell 41.
• the capsule 4 is thus perfectly stable at inside the shell 1, since it is supported on the support flanges 14 and further maintained at the fixing plate 34 on which the apphcation head 31 is itself fixed.
• the applicator pad 3 forms a supply tongue 32 which extends below the capsule 4 up to the level of the opercular film 46 at the level where it will be pierced by the needle 43. This is clearly visible in FIG. 2.
• the supply tongue 32 also passes through the window 35 formed by the fixing plate 34. This contributes still more to the cohesion of the assembly formed by the capsule and the apphcator pad 3. This embodiment is more particularly adapted to the liquid product.
• the fluid product which here can also be powdery, is directly supplied inside the application head 31 through the window 35.
• the weak weld 48 is actually placed inside the application head 31 on the other side of the window 35 relative to the body of the capsule 4. This direct supply inside the head of the tampon allows the delivery of fluid but also of powder.
• the applicator pad 3 is provided with or associated with a fixing plate 34.
• this plate is integrated into the applicator pad 3, so that the latter forms a protruding peripheral edge similar to the edge 36 of the plate 34, which is adapted to snap into the groove 13 of the body 1.
• the apphcator pad 3 has a certain rigidity or solidity at the peripheral edge of integrated fixing.
• the apphcateur pad 3 extends inside the body 1 of so that it occupies the majority of the volume. We see in particular that the applicator pad 3 extends under the capsule 4 at 38 and further surrounds the capsule 4 at 37 and 39.
• the capsule 4 is practically submerged or at least partially surrounded by the applicator pad 3.
• the applicator pad 3 forms a fixing rib 36 'which has the same function as the projecting peripheral edge 36 of the fixing plate 34.
• an applicator according to any of the embodiments illustrated here is very simple: it suffices to press on the actuating wall 10 of the shell 1 to deform or depress the dome 42 which has the effect of opening the capsule 4 and thus allowing the fluid to flow or to be driven into the apphcator pad 3. After a relatively short time, the product reaches the application head 31. It suffices then remove the cap 2 and use the body 1 as a gripping member to apply the application head 31 to the desired surface. It should also be noted that the cap 2 can not only be removed from the body 1, but that it can also be very easily replaced or fixed to the body 1 after use. Thus, even after a first application of fluid, the application head 31 can be perfectly protected by replacing the cap 2.
• the capsule, the pad and the platen of possible fixing are received or removably mounted in the body, so that one can remove the assembly (capsule and buffer and / or platinum) unitarily from the body and replace it with an identical or similar assembly.
• the body and its cap can thus be used as a reusable covering in association with one or preferably several identical or different assemblies.
• a sterile and clean fluid product applicator is obtained which can very easily be reused several times.
