Definitions

  • This patent covers a plug for containers, consisting of two elements and providing an excellent guarantee against tampering.
  • plugs are already known, mainly consisting of an external body to be periferally secured to the shaped rim of the opening in the container head and of a pouring device connected to this outer body preferably by a deformable thin wall. Before opening, the plug therefore appears to be flush with the lid, thus facilitating storage, whilst upon pouring, the pouring device can be removed to facilitate pouring.
  • Container plugs are known to be required to provide the best guarantee against tampering, to safeguard the contents of the vessel.
  • the plug must therefore be designed with a view to making tampering difficult or at least easily detectable through the presence of damage or permanent deformations.
  • plugs at present available are deficient in this respect as this is particularly true for plugs of simple design, whereas plugs consisting of more than one element are more reliable in terms of safety of the contents, though very expensive and of difficult marketability.
  • This patent therefore aims to illustrate a plug providing the highest guarantee against tampering, al low cost and attractive to container manufacturers.
  • the potential uses of the plug should extend both to containers filled through the opening in the lid, with subsequent assembly of the plug, and to containers filled through the bottom with the plug already assembled.
  • the plug meets this requirement since it consists simply of two molded elements, the first being an annular element formed by a cylindrical part connected to the closing lid, whilst the second includes the outer body, the pouring device with tear seal and an intermediate connecting part preferably consisting of a thin deformable wall.
  • the outer body of the second element has an internal U-­shaped part turned upward, into which the cylindrical wall of the first element is introduced and blocked thus acting as a firm and unmovable reinforcement inside the body.
  • the external wall of the pouring device and the inner surface of the lid have matching threads, designed not only to facilitate normal handling of the lid on the opening, but also mutual assembly of the two elements which, as a result of the already described fitting of the outer body of the second element and the cylindrical wall of the first element, will thus be tightly assembled.
  • the materials constituting the two elements are of special significance in the invention.
  • the material of the second element is fairly soft and flexible i.e. soft and flexible plastic similar to the material used for conventional plugs, since this element is fitted by plastic deformation into the container opening and is designed to allow the extraction of the delivery device if the model is provided with an extractable pouring device.
  • the first element is manufactured in rather rigid and resisting material, such as hard and rigid plastic, since the cylindrical part is the element which plays the most important role in stiffening the plug and in preventing tampering.
  • the second element of the plug as per Fig.3, consists of an annular body 1, which externally presents the well-known profiles 2, 3, 4 useful for the assembly and tightening of the plug in the opening in the head 5 of the container, suitably shaped by normal annular inward-directed bending 6 (See Fig.5).
  • the external part of body 1 presents in the lower part a U-shaped counterbend 7, forming an upward-turned recess 8 having on its outer surface an annular swelling 9 at some distance from the bottom.
  • the second element 1 also consists of a cylindrical central part 10 forming the pouring device, connected at its lower end, by an intermediate deformable thin wall 11, to the internal end of counterbend 7.
  • the pouring device 10 has internally a closing device 12 which can be removed by pulling the raised tongue 13.
  • the outer surface of the pouring device 10 is threaded 14, to facilitate positioning of the lid and assembly of the two plug elements plug, as hereinafter explained.
  • the first element of the plug is formed by an external cylindrical part 15 with an external annular swelling 16 at its lower end.
  • the closing lid 18 is positioned inside and is linked to the above-mentioned external part 15 by thin radial tearable strips 17; the lid being provided with an external upper flange 19 and an internal annular tightening projection 20 and thread 21 engaging the thread 14 of the pouring device.
  • One half of the flange 19 approximately is fastened to the lid 18, while the other half 19′ can be lifted (see Fig.5) to facilitate the extraction of the pouring device 10 of the plug as well as the screwing and unscrewing of the lid.
  • the two plug elements are assembled by screwing the thread 21 of the first element onto the thread 14 of the second one. During this operation, the external part 15 of the first element is screwed into the recess 8 of the second fixed element, until the projection 16 has got beyond projection 9 and is steadily positioned beneath the latter (see Fig. 4).
  • the plug thus assembled may be completed by a removable sealing foil 22.
  • a specific device has therefore been designed to obtain the simultaneous rotation of the lid 18, 19 with the external part 15, so as to prevent tearing of the connecting strips; moreover notches 23 on the lid and holes 24 on the upper rim of the external part 15 are also provided to permit simultaneous screwing of the first element by means of the device.
  • the notches 23 and the holes 24 may be replaced by radial serrations 25 (hatched in Fig.1 and 2), on the external upper surface of wall 15 and of the lid 18.
  • the serrations permit to screw on the lid, by acting on the vertical surfaces, thus preventing unscrewing due to slipping along the inclined surfaces.
  • the first element is manufactured in rigid and resisting material, whereas the second is in soft and flexible material.
  • the choice of these materials is determined by the fact that the second element has to be deformable so that it can fit in the shape 6 of the hole in the head 5 and to allow for deformation of the thin-walled section 11 for the extraction of the pouring device 10.
  • the rigidity and resistance of the first element are useful for the formation of the reinforcing ring represented by the external part 15.
  • Fig.5 shows the plug after its removal, ready for pouring, after the lid 18 has been removed.
  • the plug herein described can also have a non-deformable wall, in which case the plug with the pouring device cannot be extracted.
  • the patent can also be applied to plugs with extractable telescopic pouring devices.
  • the plug consists of only two elements to be screwed into each other, at low production cost and the plug provides the best guarantee against tampering since it can neither be extracted nor removed without causing visible damage to the radial strips 17 or the plug itself, in line with the scope of the invention.
