Definitions

  • the present invention relates to a sealing closure for containers of liquids.
  • substantially cylindrical disposable cork closures pushed inside the end of bottle necks, are currently mainly used for the bottling of liquids such as wine.
  • closures which are larger in diameter than their seats, sealingly close the bottles by exerting a pressure on the walls which is such as to contrast the pressures which the wines generate inside the bottles.
  • cork closures are not free from problems, including a high cost and the fact that they are subject to diseases (fungi) which give the wines an extremely unpleasant smell.
  • Closures made of high-density plastics are less widely used; they are substantially composed of a head from which there extends a tubular element suitable for being inserted in the bottle neck (see FR-A-1 576 492).
  • the tubular element is externally provided with flanges suitable for producing a seal against the walls of the neck of the bottle.
  • the aim of the present invention is to provide a new sealing closure for containers of liquids which eliminates the problems described above in known types.
  • a consequent primary object is to provide a closure which is fully non-toxic and does not have the risk of yielding unpleasant smells to the bottled liquids.
  • Another important object is to provide a closure which can also be sterilized.
  • Still another object is to provide a closure which can be manufactured with low-cost and widely available raw material.
  • Yet another object is to provide a closure which is characterized by low production costs.
  • Not least object is to provide a closure whose aesthetics is substantially equivalent to that of a conventional cork closure.
  • the closure according to the invention comprises a substantially cylindrical plastic element 1 which is conveniently made of synthetic material, preferably non-toxic foamed polystyrene for food use.
  • An also substantially cylindrical elastic insert 2 is axially embedded inside the element 1 and is preferably constituted by ground granulated cork or by high-density plastic material with resilient characteristics, or by natural or synthetic rubber.
  • the outer plastic element 1 is suitable for constituting a sort of sealing gasket on the walls of the neck of the bottle, whereas the resiliency of the internal insert 2 is suitable for producing the thrust on the walls which is necessary in order to withstand the pressures which form inside the bottle.
  • the elastic insert 2 is completely embedded in the plastic element 1 and therefore cannot yield bad smells to the liquid in any way.
  • the plastic element 1 is produced in the same shade of color as cork and therefore its aesthetics is substantially equivalent to that of conventional commercially available closures.
  • a variated embodiment of the closure according to the invention can comprise an outer plastic element 3 with conically concave end faces 4 in order to constitute guides for the point of a conventional corkscrew to be used for extraction.
  • An elastic insert 5 is embedded in the plastic element 3 in this case as well.
  • the elastic insert designated by the reference numeral 6 in figure 5, can conveniently be barrel-shaped.
  • the elastic insert which is now designated by the numeral 7, is cylindrical and has a pair of toroidal outer ridges 8 which are suitable for generating more highly compressed local regions where tightness is increased.
  • the closure comprises a substantially cylindrical elastic element 9 provided with an axially extending elastic shank 10 which is embedded in a similarly shaped seat of a substantially cylindrical plastic element 11.
  • the diameters of the elastic element 9 and the plastic element 11 are substantially equal.
  • a substantially cylindrical elastic insert 12 is axially embedded inside a substantially cylindrical plastic element 13 such that one end of the elastic insert 12 is substantially flush with the corresponding end of the plastic element 13.
  • Said closure is in fact characterized by low cost of the raw material, low production cost, complete non-toxicity and no possibility of yielding unpleasant smells to the liquid.
  • the closure can furthermore be sterilized.
