according to fig1 an applicator 1 includes a reservoir 2 in the shape of a cylinder which has a base and is open at one end ; a spacer element 10 of the same cross - section as the reservoir 2 is force - fitted through this end until a flange 26 of the spacer element 10 , of an external diameter equal to the external diameter of the reservoir 2 , abuts the frontal outer edge of the opening of the reservoir 2 . the spacer element 10 supports a finger - shaped end - piece 11 ; to do this , the spacer element 10 includes an axial cylindrical recess 13 extended via a coaxial passage 14 of smaller diameter , which is itself extended via a flared area 15 opening to the outside ; in line with this flared area 15 , the spacer element 10 has an external thread 16 on the surface of a cylindrical end portion which is of a smaller diameter than that of the part of the spacer element 10 fitted in the reservoir 2 . at the end of the spacer element 10 distinct from the end which has the thread 16 , the spacer element 10 is equipped with an annular bulge 17 for snap - in fitting ; the end - piece 11 is housed in the cylindrical recess 13 ; the end - piece 11 is in the shape of a finger and defines a cylindrical chamber 25 and a base 20 : the base 20 has a seat 24 pierced with a capillary orifice 23 ; the base 20 is bordered by a flange 21 for snap - fitting which is of a shape complementary to that of the annular bulge 17 of the spacer element 10 , allowing the end - piece 11 to be joined to the spacer element 10 by snap - fitting . the base 20 of the end - piece 11 is at a distance from the base 3 of the reservoir 2 for a substance 5 to be applied . the applicator 1 also includes a cap 4 represented partially in the figures ; the cap 4 is also in the shape of a cylinder which has a base ( not represented ) and is open at one end ; a stopper 40 having the same cross - section as the cap 4 is force - fitted through this end , the cap 4 itself having a cross - section similar to that of the reservoir 2 ; the stopper 40 is fitted into the cap 4 until a flange 45 of the stopper 40 abuts the outer edge of the opening of the cap 4 . the stopper 40 has a top 41 in which there is formed a cavity 42 extended via a bore 43 of greater diameter which has on the inside a thread 44 complementary to the thread 16 of the spacer element 10 . the stopper 40 is integral with an applicator holder 30 supporting a deformable application element 35 made in this example , of a foam ; the applicator holder 30 includes a hollow rod 31 , pierced with a bore 32 , one end of which has longitudinal fins 33 for holding the rod 31 in the cavity 42 of the top 41 by forcefitting . the other end of the rod 31 is equipped with a rigid supporting sleeve 34 in the shape of an ogive holding the deformable element 35 via its end of smaller diameter defining a constriction 36 . in an alternative which is not represented , the deformable element 35 is held directly by the hollow rod 31 . the deformable element 35 is made of a material having a considerable shape memory . in the position represented in fig1 the applicator is closed ; the cap 4 is screwed onto the reservoir , a sealing joint 50 being placed around the rod 31 , between the stopper 40 and the spacer element 10 ; in this closure position , the deformable element 35 is crushed against the seat 24 and the orifice 23 . a ball 60 is housed in the reservoir 2 and permits agitation of the substance 5 , if necessary . the orifice 23 opens into the reservoir 2 along a flared , frustoconical portion 22 . by virtue of the capillary orifice 23 , whose diameter is of the order of 0 . 5 to 3 mm , a drop 6 of substances adheres by capillarity to the surface of the base 20 opposite the seat 24 . fig2 shows the applicator 1 in an open position , just before use ; in this position , which corresponds to a position in which the cap 4 is drawn back with respect to the reservoir 2 , the deformable element 35 has recovered its initial position ; the deformable element 35 is charged with a part 8 of the drop 6 of substance , the remainder 7 of the substance obstructing the orifice 23 in which it is held by capillarity . the manner in which the deformable element 35 is charged with substance is illustrated in fig3 to 5 ; in these figures , the base of the end - piece 11 , in which the capillary orifice 23 is formed , has been represented diagrammatically . fig3 corresponds to the closed applicator , the drop 6 of substance being held by capillarity ; fig5 corresponds to the position in which the deformable element 35 is charged with a part 8 of the drop 6 of substance 5 , the orifice being obstructed by the remainder 7 of the substance 5 ; fig4 corresponds to an intermediate position in which a drop 6a is smaller than the drop 6 in fig3 the deformable element 35 having begun to be charged with substance , as it gradually recovers its original shape . the deformable element 35 can have different shapes at rest : thus , according to fig6 the deformable element 135 has a flat end ; according to fig7 the deformable element 235 has the shape of a rounded conical tip ; according to fig8 the deformable element 335 has a spherical end . the deformable element has a roughened surface which can be of any type : it can include a large number of protrusions separated by small cavities , or of fine circular and parallel grooves , as illustrated in fig7 . according to the alternatives in fig9 to 11 , the applicator holder 400 , 500 , 600 includes a solid rod 431 , 531 , 631 whose end is shaped to support the deformable element 435 , 535 , 635 , here preferably made of low - hardness elastomer ; low - hardness elastomer is understood to mean an elastomer whose hardness is between 15 shore a and 70 shore a . this elastomer is made up of open - cell foam . according to fig9 the solid rod 431 has , at its end , a cylindrical recess 432 in which an end 436 of the deformable element 435 is tightly fitted . according to fig1 , the solid rod 531 has , at its end , an annular cylindrical recess 532 bordered at the center with a stiffening element 534 of elongate shape , along the axis of the rod 531 , the axial length of the stiffening element 534 being greater than that of the recess 532 ; the deformable element 535 has a cavity 538 of a shape complementary to that of the stiffening element 534 on which it is engaged tightly , the end 536 of the element 535 being likewise fitted tightly in the recess 532 ; the stiffening element 534 makes it possible to guide the deformable element 535 during its deformation . according to fig1 , the solid rod 631 has , at its end , a stiffening element 634 , without the annular recess in the preceding alternative ; a radial protrusion 637 with which the stiffening element 634 is equipped permits a better axial support of the deformable element 635 . fig1 and 13 show an alternative of the applicator in which the capillary end - piece 11 , which limits the substance reservoir 2 , is equipped with a seat 24 pierced with several capillary slits 230 , six slits in the shape of arcs of a circle in the example represented in these figures ; these slits can of course have , in cross - section , any suitable shapes , such as , for example , those represented in fig1 / i to 16 / v ; these slits can have , in longitudinal section of the base 201 , frustoconical shapes 231 , as shown in fig1 , or partially frustoconical shapes 232 , as shown in fig1 , in such a way as to form a reserve of substance . the end - piece 11 in this alternative is made of a rigid material and has threads 203 on the outer surface of an upper part 202 thereof ; the upper part 202 is extended downwards via a flared skirt 200 surrounding the seat 24 , being at a radial distance from the latter ; the skirt 200 covers the reservoir 2 , of the hemispherical - shaped type , and is made integral with the reservoir 2 , for example by adhesive bonding ; the reservoir 2 is advantageously made of a transparent material . the threads 203 of the end - piece 11 cooperate with threads 403 on the cap 4 , which also has , on the inner face of its upper part , an annular sealing lip 404 for sealed closure of the capillary end - piece 11 , the lip 404 surrounding a solid transverse wall constituting the stopper 40 . according to fig1 , the applicator is similar to that in fig1 , except that the reservoir 2 is a flexible tube connected to the flared skirt 200 , which is in this case shorter than that in the alternative in fig1 . according to fig1 , the applicator includes an applicator holder 30 which is not integral with the cap 4 ; the applicator holder 30 , which supports the deformable element 35 , is made of a plate 301 on one face of which the element 35 is secured , while the other face of the plate 301 bears a grip 302 , the applicator holder 30 thereby constituting a sort of powder puff application . the cap 4 has , on the inner face of its upper part , a central rib 440 intended to cooperate with the grip 302 , by means of which the applicator holder 30 is applied on the seat 24 when the cap 4 is screwed on to the upper part of the end - piece 11 , by cooperation of the threads 203 and 403 on , respectively , the capillary end - piece 11 and the cap 4 ; the cap 4 also has , on the inner face of its upper part , an annular sealing lip 404 for sealed closure of the capillary end - piece 11 ; a transverse plate closes the skirt 200 at its lower part in order to form the reservoir 2 . according to fig1 , the applicator is of the same type as the applicators described with reference to fig1 to 15 , except that the capillary end - piece 11 is made of semi - rigid material , secured in the neck of the reservoir 2 , the capillary end - piece 11 being a component distinct from the reservoir 2 , as described with reference to fig1 to 11 .
