Device for dispensing a fluid substance
A device for dispensing a fluid substance comprising an outer container ( 2 ) to which a collar ( 3 ) is fastened removably, a pump ( 4 ) fastened stably to the collar ( 3 ), an inner container ( 5 ) housing a deformable bag ( 6 ) therewithin, the inner container ( 5 ) featuring a neck ( 5 A) equipped with first means ( 7 ) for connection to the collar ( 3 ) configured to cooperate with second means ( 8 ) for connecting the collar ( 3 ) so as to removably fix the inner container ( 5 ) to the collar ( 3 ), the collar ( 3 ) and the outer container ( 2 ) being fastened removably by means of a tubular element ( 9 ) endowed with a plurality of first fins ( 9 A) which secure the collar ( 3 ) to the tubular element ( 9 ) and second fins ( 9 B) which secure the outer container ( 2 ) to the tubular element ( 9 ).
1 . A dispensing device ( 1 ) of a fluid substance comprising an outer container ( 2 ) to which a collar ( 3 ) is removably attached, a pump ( 4 ) stably attached to the collar ( 3 ), an inner container ( 5 ) housing a deformable bag ( 6 ) therein, the inner container ( 5 ) having a neck ( 5 A) envisaged with first means ( 7 ) of connection to the collar ( 3 ), the first means ( 7 ) being configured to cooperate with second means ( 8 ) of connection of the collar ( 3 ) so as to removably attach the inner container ( 5 ) to the collar ( 3 ), the collar ( 3 ) and the outer container ( 2 ) being removably fixed trough a tubular element ( 9 ) provided with a plurality of first fins ( 9 A) constraining the collar ( 3 ) to the tubular element ( 9 ) and second fins ( 9 B) constraining the outer container ( 2 ) to the tubular element ( 9 ).
2 . The device according to the claim 1 , wherein, when the inner container ( 5 ) is fixed to the collar ( 3 ), a first part ( 5 B) of the inner container ( 5 ) encounters a second part ( 9 C) of the tubular element ( 9 ) so as to keep the tubular element ( 9 ) permanently associated with the collar ( 3 ).
3 . The device according to claim 1 , wherein the collar ( 3 ) defines a groove ( 10 ) in which an end of the tubular element ( 9 ) is engaged wherein said first fins ( 9 A) are present.
4 . The device according to claim 1 , wherein a first portion ( 11 ) of the tubular element ( 9 ) wherein said first fins ( 9 A) are made, has a smaller diameter than that of a second portion ( 12 ) of the tubular element ( 9 ) wherein said second fins ( 9 B) are made.
5 . The device according to claim 1 , wherein said second part ( 9 C) is made in correspondence with a connecting portion between the first portion ( 11 ) and the second portion ( 12 ) of the tubular element ( 9 ).
6 . The device according to claim 1 , wherein a sealing element ( 13 , 14 , 18 ) is provided between the pump ( 4 ) and the deformable bag ( 6 ).
7 . The device according to claim 1 , wherein the sealing element ( 14 ) is constrained to the inner container ( 5 ) or the deformable bag ( 6 ), so as to get removed from the pump ( 4 ) when the inner container ( 5 ) is separated from the collar ( 3 ).
8 . The device according to claim 7 , wherein the sealing element ( 14 ) is snap-fitted to the neck ( 5 A) of the inner container ( 5 ), and has a first sealing lip ( 14 A) on a body ( 4 A) of the pump ( 4 ) and a second sealing lip ( 14 B) on a neck of the deformable bag ( 6 ).
9 . The device according to claim 7 , wherein the sealing element ( 18 ) is made in a single piece with the deformable bag ( 6 ) and is sealingly engaged in a groove ( 4 B) of the pump ( 4 ).
10 . The device according to claim 1 , wherein the outer container ( 2 ) at an interconnection zone with the tubular element ( 9 ) is free of protrusions or recesses functional for coupling with the tubular element ( 9 ).
11 . The device according to claim 1 wherein, when the inner container ( 5 ) is decoupled from the collar ( 3 ), it has a removable cap ( 20 ) provided with a thread ( 22 ) which couples to said first means ( 7 ) of connection, the removable cap ( 20 ) being provided with a protrusion ( 21 ) which cooperates in a sealing manner with the deformable bag ( 6 ) or with the sealing element ( 14 ).
