Description
- The present invention relates to a sealing closure for containers of liquids.
- It is known that substantially cylindrical disposable cork closures, pushed inside the end of bottle necks, are currently mainly used for the bottling of liquids such as wine.
- The 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.
- However, although they are extensively used, 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.
- Another problem is the scarce availability of raw material, due to the fact that the barks of cork-yielding trees require several years to reconstitute.
- 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.
- These closures owe their scarce diffusion to their unpleasant aesthetics and to the fact that the seal is localized in a small number of flange lines and is therefore troublesome.
- Furthermore, conventional corkscrews suitable for cork closures cannot be used to extract said plastic closures.
- 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.
- This aim, these objects and others which will become apparent hereinafter are achieved by a sealing closure for containers of liquids according to
claim 1. - Further characteristics and advantages of the invention will become apparent from the detailed description of some embodiments thereof, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
- figure 1 is a perspective view of a first embodiment of the closure according to the invention;
- figure 2 is a longitudinal sectional view of the first embodiment of the closure according to the invention;
- figure 3 is a perspective view of a second embodiment of the closure according to the invention;
- figure 4 is a longitudinal sectional view of the embodiment of figure 3;
- figure 5 is a perspective view of a first embodiment of the insert which is embedded in the closure structure according to the invention;
- figure 6 is a perspective view of a second embodiment of the insert which is embedded in the closure structure according to the invention.
- figure 7 is a perspective view of a third embodiment of the closure according to the invention;
- figure 8 is a longitudinal sectional view of the closure of figure 7;
- figure 9 is a perspective view of a fourth embodiment of the closure according to the present invention; and
- figure 10 is a longitudinal sectional view of the closure of figure 9.
- With reference to the above figures, 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 theelement 1 and is preferably constituted by ground granulated cork or by high-density plastic material with resilient characteristics, or by natural or synthetic rubber. - According to the invention, 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 theinternal 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 theplastic 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, illustrated in figures 3 and 4, can comprise an outer
plastic element 3 with conicallyconcave 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 theplastic element 3 in this case as well. - In order to increase thrust in the median region, the elastic insert, designated by the reference numeral 6 in figure 5, can conveniently be barrel-shaped.
- In another case, shown in figure 6, 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. - According to a further aspect of the present invention, as seen in figures 7 and 8, the closure comprises a substantially cylindrical
elastic element 9 provided with an axially extendingelastic shank 10 which is embedded in a similarly shaped seat of a substantially cylindricalplastic element 11. The diameters of theelastic element 9 and theplastic element 11 are substantially equal. - According to a further aspect of the present invention, as seen in figures 9 and 10, a substantially cylindrical
elastic insert 12 is axially embedded inside a substantially cylindricalplastic element 13 such that one end of theelastic insert 12 is substantially flush with the corresponding end of theplastic element 13. - In practice it has thus been observed that the closure according to the invention has achieved the intended aim and objects.
- 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.
- By virtue of the presence of the external element made of foamed polystyrene, the closure can furthermore be sterilized.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the scope of each element identified by way of example by such reference signs.
