Definitions

  • the present invention relates to a closure structure particularly for containers of nebulizable liquids, for example paints, oils, etc.
  • Dispensers substantially constituted by two concentric tubular elements are currently used to spray nebulizable liquids; the inner tubular element is connected to a pressurized air duct and the outer one is connected to a liquid drawing duct which extends perpendicular from said outer tubular element inside a threaded ring to be screwed to the mouth of a liquid container.
  • the dispenser is unscrewed from the container, and a ring closure is placed on said container.
  • the aim of the present invention is to provide a closure which, optionally provided to a nebulizable liquid container, can also be used as a dispenser by means of a simple coupling to a compressed-air dispenser gun.
  • a consequent primary object is to provide nebulizable liquid containers with a sort of disposable dispenser.
  • Another object is to provide a closure which can be manufacture on a large scale and at low cost for example by molding thermoplastic materials, by pressure die-casting metallic material, etc.
  • Not least object is to provide a closure which can be marketed even individually and used as a low-cost dispenser.
  • a closure structure particularly for nebulizable liquid containers comprising a disk-like element with an optionally threaded axial ring, characterized in that a tubular element extends on said disk-like element, and is connected to a coupling which is internal to said ring for a liquid drawing duct, said tubular element being substantially perpendicular or inclined and having a first end shaped like a dispenser nozzle and a second end provided with means for coupling to a gun for dispensing gases, mixtures of gases and/or fluids under pressure.
  • the closure structure according to the invention is generally indicated by the reference numeral 1 and comprises a disk-like element 2 from which an axial ring 3 extends downward; said ring is conveniently provided with an internal thread 4 for coupling on a complementarily threaded mouth 5 which extends from a nebulizable liquid container 6, for example paint, oil, etc.
  • said mouth 5 is provided with a tear-open sealing membrane 7 in order to preserve the integrity of the contents prior to sale.
  • a tubular element 8 extends diametrically on said disk-like element, is monolithic therewith, perpendicular to the axis and connected to an axial coupling 9 provided inside the ring 3.
  • Said coupling 9, which is appropriately grooved or threaded, is suitable for being inserted inside a tube 10 for drawing the liquid of the container 6.
  • said tubular element 8 has a first end 11 which is tapered like a dispenser nozzle with a portion of internal duct 12 which has a reduced diameter and is blended, by means of a frustum-shaped portion 13, to the rest of the duct 14, which has a greater diameter, of said element 8.
  • a second end 15 of the element 8 is threaded and is suitable for coupling to a complementarily threaded end portion 16 of a known gun 17 for dispensing gases, mixtures of gases and/or fluids under pressure, for example compressed air.
  • the dispenser 18 of the gun 17 thus penetrates inside the tubular element 8 and defines, inside the duct 14, a chamber in which nebulization occurs between the compressed air and the liquid, which is drawn from the inside of the container 6 by negative pressure.
  • the closure structure 1 is completed by a vent hole 19 which passes axially through the disk-like element 2.
  • the structure according to the invention has the dual function of closure suitable for opening the sealing membrane 7 and of dispenser when it is necessary to spray the liquid of the container 6.
  • the closure structure according to the invention can be either included in the package of the container 6 and thus disposed when said container has depleted its contents, or can be sold separately for use on any container provided with a mouth.
  • the ring 3 may also be not threaded but provided with annular grooves, or may even be smooth, to be coupled by means of simple insertion on the mouth.
  • the preferred materials can either be of the thermoplastic type or be pressure die-cast metals so that large-scale and low-cost production is allowed.
  • the materials employed may be any according to the requirements.
