Securing system and fluid product dispenser using such a system

Abstract

A fastener system ( 1, 2 ) for fastening a dispenser member ( 3 ), such as a pump, on a reservoir neck ( 41 ) so as to constitute a fluid dispenser, the dispenser being removable by removing the fastener system from the neck, the system comprising a fastener ring ( 1 ) and a rigid hoop ( 2 ) that is engaged around the fastener ring, the ring ( 1 ) comprising a skirt ( 14 ) for engaging around the neck ( 41 ), the skirt ( 14 ) including fastener tabs ( 15 ) for coming into secure engagement with the neck ( 41 ), the fastener system being characterized in that the skirt ( 14 ) further includes at least one abutment tab ( 16 ) for coming into axial abutment against the neck ( 41 ) when an attempt is made to re-assemble the fastener ring ( 1 ) on the neck ( 41 ) after the dispenser has been removed for the first time.

         11 . A fastener system ( 1 ,  2 ) for fastening a dispenser member ( 3 ) on a reservoir neck ( 41 ) so as to constitute a fluid dispenser, the dispenser being removable by removing the fastener system from the neck, the system comprising a fastener ring ( 1 ) and a rigid hoop ( 2 ), the ring ( 1 ) comprising a skirt ( 14 ) for engaging around the neck ( 41 ), the skirt ( 14 ) including fastener tabs ( 15 ), the hoop ( 2 ) is then engaged around the skirt ( 14 ) in such a manner as to push the fastener tabs hard against the neck ( 41 ), the ring ( 1 ) with the hoop ( 2 ) engaged around the skirt being removable from the neck, the fastener system being characterized in that the skirt ( 14 ) further includes at least one abutment tab ( 16 ) that projects radially outwards before the hoop ( 2 ) is engaged around the skirt ( 14 ), the abutment tab ( 16 ) is deformed radially inwards by the hoop ( 2 ) and pushed elastically against the neck, and after removal of the dispenser the abutment tab ( 16 ) projects radially and relaxes elastically inwards relative to the fastener tabs ( 15 ) so as to come into abutment against the reservoir neck ( 41 ) when an attempt is made to re-assemble the fastener ring ( 1 ) on the neck ( 41 ) after the dispenser has been removed for the first time. 
     
     
         12 . A fastener system according to  claim 11 , wherein the abutment tab ( 16 ) comprises a top section ( 161 ) having a bottom end ( 163 ) and a top end ( 162 ) that is connected to the remainder of the ring, and a bottom section ( 164 ) having a top end ( 165 ) that is connected to the bottom end ( 163 ) of the top section, the two sections ( 161 ,  164 ) extending relative to each other, forming an angle between them, the top section ( 161 ) flaring outwards before the hoop is engaged around the skirt. 
     
     
         13 . A fastener system according to  claim 12 , wherein the abutment tab ( 16 ) is deformed inwards permanently by the hoop ( 2 ) at the top end ( 162 ) of the top section ( 161 ) that is connected to the remainder of the ring. 
     
     
         14 . A fastener system according to  claim 12 , wherein the top section ( 161 ) extends axially and the bottom section ( 164 ) extends inwards after the hoop ( 2 ) has been engaged around the skirt ( 14 ). 
     
     
         15 . A fastener system according to  claim 12 , wherein the hoop ( 2 ) comes into contact with the top section ( 165 ), the bottom section ( 163 ) being deformed elastically, in non-permanent manner, against the neck ( 41 ). 
     
     
         16 . A fastener system according to  claim 11 , wherein the abutment tab ( 16 ) includes a free bottom end ( 166 ) that is in contact with the neck ( 41 ), with non-permanent elastic deformation. 
     
     
         17 . A fastener system according to  claim 12 , wherein the fastener tabs include profiles ( 151 ) that are deformed plastically against a thread ( 42 ) of the neck ( 41 ). 
     
     
         18 . A fastener system according to  claim 11 , including a plurality of abutment tabs ( 16 ) that are arranged in alternating manner between the fastener tabs ( 15 ). 
     
     
         19 . A fluid dispenser comprising a fluid reservoir ( 4 ) including a neck ( 41 ), a dispenser member ( 3 ), such as a pump, and a fastener system ( 1 ,  2 ) according to  claim 11 , wherein the hoop ( 2 ) causes the abutment tab ( 16 ) to pivot inwards permanently, and presses it elastically against the neck ( 41 ) of the reservoir ( 4 ). 
     
     
         20 . A dispenser according to  claim 19 , wherein the neck ( 41 ) includes an external thread ( 42 ), the fastener tabs ( 15 ) being engaged with the external thread ( 42 ) of the neck, the hoop ( 2 ) pushing the fastener tabs ( 15 ) against the neck ( 41 ). 
     
     
         21 . The fastener system according to  claim 11 , wherein the dispenser member is a pump. 
     
     
         22 . The dispenser according to  claim 19 , wherein the dispenser member is a pump.
