Definitions

  • the invention relates to a method for producing a cork stopper, in particular a stopper having the body of cork conglomerate and at least one end section of natural cork with the pores in a direction perpendicular to the longitudinal axis of the stopper.
  • cork conglomerate stoppers were produced to have an industrial production of high yield and good quality, in the same time. But in these corks, the liquid contained in the bottle, for example wine, comes into contact not only with the cork granules, but also with their binder.
  • cork conglomerate stoppers are produced having a natural cork section at least at the end which must come into contact with the liquid contained in the containers (FR-A-1349033). Obviously, it is preferable that both ends of the stopper have a natural cork section.
  • Document FR-A-1219526 describes a process which produces long bars made up of alternating longitudinal succession of parts of agglomerated cork and parts of natural cork, each of said bars being polished and sectioned into sections which include a part of agglomerated cork and part of natural cork.
  • the cork parts according to the figures, show the pores in the longitudinal direction.
  • Some of these corks have the drawback that the natural cork section has the pores parallel to the axis of the cork and this still allows the liquids contained in the bottles to reach the cork granules and their binder.
  • EP-A-100302 has exposed a method which reveals a cork conglomerate stopper with natural cork end sections obtained as follows: forms a parallelepiped block which has the main part in cork conglomerate and at least one face belonging to a sheet formed by strips of natural cork glued laterally between them and having their pores parallel to the sheet itself; the block is punched perpendicular to the base faces to draw a plurality of plugs therefrom.
  • the invention as characterized by the claims, therefore relates to a method for producing a stopper having the main body of cork conglomerate and at least one end section of natural cork with the pores perpendicular to the axis of the stopper comprising the stages of: a) producing a main cork conglomerate body in the prescribed diameter and height; b) producing at least one circular section of natural cork in a single piece having said diameter and the pores in a perpendicular direction; c) transfer and fix on at least one end of said main body at least one of said circular sections.
  • Stage b) can be carried out by cutting said section of cork from a cylindrical bar of natural cork having said diameter and the pores in a perpendicular direction or by punching said section with a strip of natural cork having pores parallel to the strip.
  • the main advantage of the invention lies in the fact of providing a stopper which has at least one end section in a single piece of natural cork with the pores in a perpendicular direction and for this the stopper does not have any way of penetration of the liquid. in the conglomerate body (it goes without saying that at least one section of natural cork is attached to one end of the stopper in cases where it is possible to orient the stopper before closing the bottle).
  • FIG. 1 shows a body of cork conglomerate 1, having the diameter D and height H, intended for the production of a cork stopper 4, as illustrated in FIG. 3, comprising the body of cork conglomerate 1 and the terminal sections in a single piece S1, S2 in natural cork with the pores 3 in a perpendicular direction.
  • a cylindrical bar made of natural cork 2 having diameter D equal to the diameter of said body 1, and with its perpendicular pores 3. From such a bar 2 we can draw a plurality of sections Sn. Two sections S1, S2 of appropriate height h are cut from the bar and transferred (see arrows F) and glued, respectively, to the upper and lower end of said body 1 to provide a finished plug 4 having the specified height H1.
  • FIG. 2 also shows one of said bodies 1 and a flat strip 5 of natural cork having a suitable thickness and the pores 3 parallel to a plane of the strip itself.
  • Two washers R1, R2 with the same diameter D of the body 1 are stamped with this flat band and transferred (see arrows F) and glued to the upper and lower ends of the body 1 to obtain a stopper equal to that indicated by 4 in Figure 3.
  • FIG. 3 shows the plug already said: the conglomerate body 1 carries the washers R1, R2 respectively glued at its two ends.
  • the height H1 of the finished plug is that prescribed.
  • a plug can also carry more than one of these sections or washers on only one or both of the ends.
