Definitions

  • the upper part comprises a closure part provided with the said at least one exit or pouring opening and connected to a fastening ring by at least one predetermined breaking wall having a transverse, inclined or perpendicular orientation with respect to the axis of the pouring device, i.e.
  • Anti-refilling closing devices of this kind are known from the document GB 2 057 390 A for a perpendicular orientation of the predetermined breaking wall with respect to the axis of the pouring device, and from the documents EP 0 249 438 A and EP 0 367 427 A concerning the inclined orientation of the predetermined breaking wall.
  • the invention also relates to other improvements which form the subject of the dependent claims.
  • an anti-refilling closing device is composed of a pouring device, or more briefly and simply pourer 1, generally made of plastic, which is a non-return valve to prevent the bottle from being zefilled, allowing to freely pour the contents thereof.
  • the cylindrical pourer 1 is outwardly provided, in the area which is meant for force-engagement into the mouth 2 of the bottle, with outer, substantially radial, annular and elastic flanges 3.
  • the pourer 1 has, inside it, a cylindrical compartment 4 communicating with the inside of the bottle B through a central opening 5 at the inward end of the pourer, which opening may be closed by means of a ball-like plugging body 6, which is gravity-operated and may move freely, axially to the pourer 1, between a closing position and an opening position of the passage opening 5.
  • the diameter of the compartment 4 for the plugging body 6 is greater than that of the ball, with the ball being held substantially centered by means of radial guiding ribs 7 uniformly arranged all along the wall of the compartment 5.
  • the opposite end, that is the outward end, of the pouring device 1 is closed by an element 8, which has a flange 9 superimposed on the lateral edge of the mouth of the bottle, and bears in a central area, coaxial to the compartment, a basket 10, having substantially coaxial pouring openings 11.
  • the basket 10 has, in its central area, an inverted cup-shaped element 12, extending upwards up to about the level of the flange 9 superimposed on the edge of the mouth 2 of the bottle B, and whose terminal part, facing the ball 6, has a concave, preferably spherical shape, acting as a compartment for the ball 6, when the latter is in the pouring condition.
  • the central basket 10 is held suspended in the central area of the compartment 4 for the ball by the flange 9, superimposed on the edge of the mouth of the bottle, whereas the combination of superimposed flange 9 and basket 10 is connected, by a relatively thin radial annular wall 13 to a ring 14, fastening the closing part 8 of the pourer to the inward part thereof, which may be force-secured into the mouth 2 of the bottle B.
  • the fastening ring 14 has, on its outer periphery, at least one annular tooth 15, preferably having a sawtooth cross section, for snap engagement with an annular groove 16 in the inner wall of the compartment 4 for the ball 6.
  • the fastening ring 14 and the wall of the compartment 4 have two annular teeth 15 and two annular grooves 16 respectively.
  • the diameters are chosen in such a way as to ensure a sealing contact between the two walls.
  • the annular teeth 15, as well as the corresponding grooves 16, may include two or more teeth and two or more notches, distributed along the perimeter of the corresponding parts.
  • a stopper 20 is associated to the pouring device 1, consisting of an outer cap made of a plastic metal material.
  • the outer cap 21 comprises a part 121, meant to be wrapped around the bottle neck and a part 221, being provided with a thread (fig. 2) on mounting the device onto the bottle B, for example by roll forming on the outer thread 22 provided on the mouth 2 of the bottle B.
  • the two capsule parts 20, 21, are connected by predetermined breaking means or, alternatively, by tear guarantee strips, indicated, as a whole, as 321.
  • a sealing disk 23 is fixed thereto, being engaged with its peripheral edge behind an annular shoulder 421 of the screw part of the stopper 221.
  • This is preferably made of the same material as the pouring device 1, and has a first peripheral flexible sealing lip 24, which is meant to interact with the flange 9 superimposed on the edge of the mouth 2 of the bottle B.
  • the main sealing action is provided at the central basket 10.
  • the sealing disk 23 has a cylindrical protrusion 25, which is coaxial to the central basket 10, and is meant to sealingly interact with the cylindrical or substantially cylindrical edge of the central basket 10, particularly in the area in which the latter is jointed to the flange 9, superimposed on the edge of the mouth 2 of the bottle.
  • the size of the basket 10, that is of its upper cylindrical part, and of the central cylindrical protrusion 25 of the sealing disk 23 are appropriately calibrated to ensure the necessary sealing action.
  • the main sealing area between the sealing disk 23 and the pouring device is transferred to the axial, non-horizontal walls.
  • the penetrating action of the cylindrical projection 25 into the cylindrical mouth of the basket 10 performs, thanks to the screwing action, a certain cleaning action through the rubbing of the walls in mutual sealing contact, further preventing loss risks, due to product remains, not to mention that the vertical orientation of the sealing walls involves a certain defluxion of the remains from the sealing walls.
  • the teeth 26 are made to be tapered towards the free end of the cylindrical protrusion, so as to facilitate the coupling operation.
  • the elasticity of the material allows for an easy disengagement of the sealing disk from the central basket, being also facilitated by the rotation of the sealing disk 23 and by the progressive removal, upon rotation, of the threaded part of the stopper 221, the whole without damaging the weakened radial wall 13.
  • the teeth 26 may also taper in the circumferential direction with a draft wall, towards the outer surface of the cylindrical protrusion 25, frontally with respect to the direction of the uscrewing rotation of the stopper 221.
  • the invention provides that the predetermined breaking annular wall 13' has an inclined, substantially truncated cone-shaped profile.
