Bottle for dispensing a fluid product equipped with a filling valve

Abstract

A bottle for dispensing a fluid product including a body with a filling valve having a jet with an internal channel extending between an upstream orifice emerging on an external wall of the jet and a downstream orifice, the jet mounted in translation in a ring having an internal length delimiting an opening for introduction of the outlet tube, the external wall in the closure position being in abutment on the internal length while disposing in the opening a central length in which the upstream orifice emerges, the valve also including an external seal interposed between the external wall and the internal length, the seal having a hole opposite the upstream orifice and an actuation area in the opening opposite the central length, the actuation area being arranged to allow filling by putting the outlet tube in sealed abutment on it to move the jet into the communication position.

1 . A bottle for dispensing a fluid product comprising a body in which a reservoir intended for packaging said product is formed, said bottle also comprising a device for taking of said packaged product that is mounted sealingly on said body, said body also being equipped with a valve for filling said reservoir that is arranged to enable an outlet tube of a source product to be put in communication with said reservoir, said bottle being characterised in that the valve has a jet provided with an internal channel that extends between an upstream orifice emerging on an external wall of said jet and a downstream orifice, said jet being mounted in translation in a ring secured to the body between a stable position of closing the downstream orifice and a stressed position of putting the internal channel in sealed communication with the packaging reservoir, the ring having an internal length delimiting an opening for introduction of the outlet tube, the external wall of the jet in the closure position being in abutment on said internal length while disposing in said opening a central length in which the upstream orifice emerges, said valve also comprising an external seal that is interposed between said external wall and said internal length, said seal having a hole disposed opposite the upstream orifice and an actuation area disposed in the opening opposite the central length, said actuation area being arranged so as to allow filling by putting the outlet tube in sealed abutment on it in order to move the jet into the communication position. 
     
     
         2 . The bottle according to  claim 1 , characterised in that the opening has an outside diameter that is greater than the diameter of the hole of the external seal. 
     
     
         3 . The bottle according to  claim 2 , characterised in that the difference between the outside diameter of the opening and the diameter of the hole is between 2.4 mm and 2.8 mm. 
     
     
         4 . The bottle according to  claim 2 , characterised in that the opening has an outside diameter that is between 3.8 mm and 4.2 mm. 
     
     
         5 . The bottle according to  claim 2 , characterised in that the opening is delimited by an edge, said edge forming a chamfer having an outside diameter that is less than the inside diameter thereof. 
     
     
         6 . The bottle according to  claim 1 , characterised in that the hole of the external seal has a diameter that is between 1.3 mm and 1.5 mm. 
     
     
         7 . The bottle according to  claim 1 , characterised in that the external seal has an annular geometry with flat surfaces. 
     
     
         8 . The bottle according to  claim 1 , characterised in that the jet has a shoulder on which the external wall is formed, said shoulder being mounted in the ring while forming a peripheral clearance with a wall of said ring, the external seal having an external edge that is disposed in rubbing sealed contact on said wall, said clearance being arranged so as to allow movement of said edge with respect to said wall in order to break the seal of the rubbing contact. 
     
     
         9 . The bottle according to  claim 1 , characterised in that the body has an opening in which the downstream end of the jet is slidably mounted, said end being provided with at least one downstream orifice that is movable between a closed-off stable position and a stressed position in communication with the opening. 
     
     
         10 . The bottle according to  claim 9 , characterised in that the valve has an internal seal affording sealed closure of the downstream orifice in the closed-off position. 
     
     
         11 . The bottle according to  claim 1 , characterised in that the body has a bottom cage in which the ring is sealingly fixed. 
     
     
         12 . The bottle according to  claim 1 , characterised in that the body has a tubular base with which a cover is associated, the taking of device being fixed to said cover. 
     
     
         13 . The bottle according to  claim 12 , characterised in that the tubular base and the cover each have an annular wall, said walls being associated by welding. 
     
     
         14 . The bottle according to  claim 1 , characterised in that the taking of device is of the type without takeup of air in the packaging reservoir in compensation for the volume of product dispensed. 
     
     
         15 . The dispensing bottle according to  claim 1 , characterised in that the reservoir has a maximum capacity C 0 , the volume C 1  of product packaged in said reservoir being such that the ratio C 0 /C 1  is between 100/40 and 100/80. 
     
     
         16 . The bottle according to  claim 13 , wherein said walls are associated by rotary friction welding.
