Claim:
Refill device ( 1 ) for a first receptacle ( 6 ), a perfume flask, and provided with a first threaded neck ( 60 ) and an atomization head, comprising: a) a receptacle, called the second receptacle ( 2 ), designed to contain a liquid product to be transferred into the said first receptacle ( 6 ), typically perfume, b) a means of cooperation ( 4 ) designed to form a sealed connection between the said first ( 6 ) and second ( 2 ) receptacles, c) a means ( 3 ) of closing off the said second receptacle ( 2 ), d) a means ( 5 ) of transferring the said product contained in the said second receptacle ( 2 ) to the said first receptacle ( 6 ), in which: 1) the said cooperation means ( 4 ) includes a threaded base ( 40 ), the said first neck ( 60 ) and the said base ( 40 ) being capable of cooperating by a so-called main screwing, the said first neck ( 60 ) comprising an external thread ( 600 ) and the said base ( 40 ) comprising an internal thread ( 400 ), so as to assure total or partial transfer of the said product contained in the said second receptacle, into the said first receptacle, 2) the said closing means ( 3 ) comprises a wall ( 30 ) closing off the said base ( 40 ), at least one portion ( 31 ) of the said wall ( 30 ) being designed to be broken off by an axial force, 3) the said transfer means ( 5 ) comprises an axial packing ( 50 ) placed or designed to be placed above the said portion ( 31 ) of the wall, such that during the said main screwing, the said first neck ( 60 ) and a locking ring ( 601 ), moves or pushes the said axial packing ( 50 ) into contact with the said wall portion ( 31 ), such that the said axial packing ( 50 ), applying the said axial force on the said portion ( 31 ) of the wall through its lower part ( 500 ), breaks or perforates the said wall portion ( 31 ), and such that the said first ( 6 ) and second ( 2 ) receptacles are put into communication and cooperating through the said main screwing, enabling the said transfer, typically by gravity, of the fluid product contained in the said second receptacle ( 2 ) to the said first receptacle ( 6 ), the said second receptacle ( 2 ) being placed above the said first receptacle ( 6 ), 4) the said wall portion ( 31 ) includes a peripheral area ( 310 ) that is completely or partly thinned, so as to form an area of weakness facilitating total or partial breakage of the said wall portion ( 31 ) when the said axial force is applied to it.
