Abstract

Dispenser (1) of a liquid, made of a single piece of moulded plastic material, comprising a first part (2) provided with a first flange (2A) from which a first tubular portion extends (2B) on top of which sealing means (3) are formed which are configured to couple with a mouth of a bottle to which the dispenser may be associated, the first flange (2A) defining an opening (4) for access to a compartment (6) which is perimetrically delimited by the tubular portion (2B), the dispenser further comprising a second part (5) hinged to the first part (2), provided with an intermediate portion (5A) from which a second tubular portion (5B) extends, which is configured to fit tightly inside the opening (4), and a metering nozzle (5C) which is internally hollow and provided with a dispensing port (7), the metering nozzle extending from the intermediate portion (5A) on the opposite side with respect to that from which the second tubular portion (5B) extends.

1 . Dispenser ( 1 ) of a liquid, in particular of electronic cigarette liquid, made of a single piece of molded plastic material, comprising a first part ( 2 ) provided with a first flange ( 2 A) from which a first tubular portion extends ( 2 B) on which are formed sealing means ( 3 ) configured to couple with a mouth of a bottle to which the dispenser can be associated, the first flange ( 2 A) defining an opening ( 4 ) for access to a compartment ( 6 ) perimetrically delimited by the tubular portion ( 2 B), the dispenser further comprising a second part ( 5 ) hinged to the first part ( 2 ), provided with a intermediate portion ( 5 A) from which a second tubular portion ( 5 B) extends, configured to fit tightly inside the opening ( 4 ), and of a metering nozzle ( 5 C) internally hollow and provided with a dispensing port ( 7 ), the metering nozzle ( 5 C) extending from the intermediate portion ( 5 A) on the opposite side with respect to that from which the second tubular portion ( 5 B) extends. 
     
     
         2 . Dispenser ( 1 ) according to  claim 1 , wherein at least a part of the peripheral surface of the first intermediate portion ( 5 A) extends beyond the perimeter of the first flange ( 2 A) when the intermediate portion ( 5 A) rests on the first flange ( 2 A). 
     
     
         3 . Dispenser according to  claim 1 , in which the first flange ( 2 A), seen in plan view, defines a first rectilinear portion ( 8 A) where the second part ( 5 ) is hinged, and a second rectilinear portion ( 8 B), the first and the second rectilinear portions being interconnected by circular arcs. 
     
     
         4 . Dispenser according to  claim 1 , wherein from the intermediate portion ( 5 A), form the same side of the metering nozzle ( 5 C), a projecting wall ( 9 ) extends, configured to facilitate, providing a thrust surface for a user, the opening of the second part ( 5 ) when the latter is fitted in the opening ( 4 ). 
     
     
         5 . Dispenser according to  claim 1 , in which the second tubular portion ( 5 B) is provided with a sloped end portion ( 10 ), and with a frusto-conical sealing surface ( 11 ). 
     
     
         6 . Dispenser according to  claim 1 , in which the sealing means ( 3 ) comprise a frusto-conical surface and/or at least a perimetral swelling ( 12 ) of the outer surface of the tubular portion ( 2 B). 
     
     
         7 . A container of a liquid comprising a bottle ( 20 ) provided with a threaded neck ( 20 A), which defines a mouth ( 20 B) of the bottle, a dispenser ( 1 ) according to  claim 1 , with the tubular portion ( 2 B) inserted into the mouth ( 20 B) of the bottle and with the first flange ( 2 A) abutting against a free surface of the mouth ( 20 B), and an anti-child safety cap ( 30 ) screwed to the neck ( 20 A) of the bottle, the inside of the cap ( 30 ) providing a space large enough to house the metering nozzle ( 5 C). 
     
     
         8 . Container according to  claim 7 , wherein the container is partially filled of a first liquid (L), preferably of an electronic cigarette. 
     
     
         9 . Method for obtaining a mixed liquid, comprising the steps of:
 removing the cap ( 30 ) of a container according to  claim 8 ,   turning the second part ( 5 ) around the hinging ( 18 ) with the first part ( 2 ), so as to free the opening ( 4 ),   pouring an additional liquid into the opening, in particular of electronic cigarette liquid, to mix it with the first liquid (L) contained in the container,   turning the second part ( 5 ) around the hinging so as to insert it into the opening ( 4 ), and   repositioning the cap ( 30 ) on the container by screwing it to the neck ( 20 A).
