Definitions

  • the present invention relates to the field of corking bottles containing sparkling wines, or any drinks or carbonated liquids.
  • a particularly interesting application of the invention relates to the corking of bottles of Champagne wines.
  • Such stoppers for sparkling wines have a part inserted in the compressed state into the bottle neck called the sealing part and a part which protrudes from the bottle neck called the head part.
  • the head part of the stopper substantially returns to its initial shape while the sealing part remains compressed radially to the inside diameter of the bottle neck.
  • the corks adopt a mushroom shape characteristic of a relatively long bottling.
  • stoppers for Champagne wines comprise a body made of natural cork and one or more washers fixed to the lower end of this body and also made of natural cork. Such stoppers are generally called “all cork” stoppers.
  • stoppers made entirely of natural cork do not make it possible to ensure good sealing of the bottle neck, which can cause so-called pouring bottles to be obtained.
  • the body of natural cork is replaced by a body made of agglomerated cork.
  • the agglomerated cork body of such stoppers is made of natural cork granules bonded together by glue.
  • adjuvants can also be added to this body.
  • the glue and adjuvants are derived from fossil resources, non-renewable and with a high carbon footprint.
  • the present invention aims to provide a stopper for sparkling wines, in particular of the Champagne type, or gaseous liquid making it possible to reduce the consumption of fossil materials without altering the stoppering properties of the sealing part of the stopper.
  • the invention relates to a stopper for sealing a neck of a bottle of sparkling wine or gaseous liquid extending along a longitudinal axis, and comprising a stopper body and at least one lower washer made of natural cork fixed to a lower end. of said plug body.
  • the stopper further comprises, fixed to an upper end of the stopper body, at least one upper washer of natural cork with a grain oriented transversely to the longitudinal axis of said stopper.
  • the stopper body is made of natural cork with a grain oriented along the longitudinal axis of said stopper.
  • natural cork veining is understood to mean the veins corresponding to the stopping of growth of natural cork cells during the winter period.
  • grain oriented transversely to the longitudinal axis of said stopper is meant that the grain is oriented in a general direction perpendicular, or substantially perpendicular, to the longitudinal axis of the stopper.
  • grain oriented along the longitudinal axis of said stopper is meant that the grain is oriented in a general direction parallel, or substantially parallel, to the longitudinal axis of the stopper.
  • the Applicant has determined that the orientation of the veining of the natural cork of the stopper body combined with the orientation of the veining of the natural cork of said upper washer makes it possible to obtain a sealing quality similar to that of the aforementioned conventional corks with a body in agglomerated cork, and also significantly improves the sealing obtained with existing "all cork" stoppers.
  • the orientation of the veining of the cork of said upper washer makes it possible to obtain a more rigid washer, in particular after the wire-wrapping operation, which contributes to a better seal on the rim of the associated bottle neck.
  • the stopper of the invention is produced by assembling parts which are made of natural cork, which greatly reduces the proportion of fossil materials.
  • the stopper body is formed from a plurality of parts assembled together and stacked transversely to the longitudinal axis of said stopper.
  • the stopper body is formed from at least three parts.
  • the production of the stopper body in several parts, preferably three, stacked along a transverse axis is particularly advantageous insofar as this makes it possible to ensure good sealing in the radial direction inside the associated bottle neck, even if the The quality of the natural cork of one of the parts of the stopper body is less good.
  • the other part (s) of the stopper body which tend by elasticity to resume their initial volume in reaction to their radial compression inside the bottle neck, act radially on this part of the stopper body which promotes retention. radial contact between this part and the bottle neck.
  • the adjacent parts of the stopper body are assembled together along a fixing plane parallel to the longitudinal axis of said stopper. This facilitates the manufacture of the stopper body.
  • the parts of the stopper body can be assembled together by gluing.
  • the natural cork of said lower washer has a veining oriented transversely to the longitudinal axis of said stopper.
  • the distance H 1 separating a lower end face of said lower washer from an interface between the stopper body and said upper washer is greater than or equal to 50% of the total height H of the stopper.
  • interface between the stopper body and said upper washer is understood to mean the area or plane of attachment of the stopper body to this washer. This fixing can for example be carried out by gluing.
  • lower end face of said lower washer is understood to mean the face of the washer intended to come into contact with the wine.
  • the stopper may have, before corking, a shoulder delimiting a bearing surface intended to come into contact against the rim of the bottle neck.
  • This shoulder may be located in a radial plane containing the interface between the stopper body and said upper washer.
  • the shoulder can be offset axially on the side of said lower washer with respect to said interface.
  • tapping from the bottle neck is meant the annular end surface of the bottle neck.
  • the stopper has, before plugging, a generally frustoconical shape widening out on the side of said lower washer.
  • the invention also relates to a bottle containing an effervescent wine or a gaseous liquid provided with a neck delimiting a drink and comprising a stopper as defined above.
  • Said lower washer and at least part of the stopper body form a sealing portion sunk into the bottle neck.
  • Said upper washer forms at least in part a head portion of the stopper projecting from the bottle neck.
  • the invention also relates to a method of capping a neck of a bottle of sparkling wine or gaseous liquid, using a stopper as defined above, in which the stopper is compressed over its entire height, then is pushed in. in the bottle neck until an interface between the stopper body and said upper washer is located in a radial plane containing the mouthpiece of said neck or is offset axially outwardly of the neck relative to said mouthpiece.
