Definitions
- the present invention relates to a composite stopper with controlled permeability for corking bottles, in particular wine bottles, comprising a body made of a compressible material such as cork, provided at least at its end facing the contents of the bottle to butcher of complementary means forming joint.
- the additional means forming a seal may consist of sheets, films, coatings, discs, etc., made of synthetic material, rubber, elastomer, for example silicone elastomer, covering at least all from the end face of the cork turned towards the content of the corking bottle.
- cork in wine corking is linked to the exceptional qualities of this material, namely the almost rot-proofness, the compressibility, the elastic return, the sealing, the ease of machining from the raw oak bark. -cork, the ability to allow possible gas exchanges, good behavior over time, etc.
- cork is also the source of certain organoleptic deviations due to an interaction with wine.
- the cork stopper is sometimes incapable of ensuring total liquid tightness at the cork-glass interface, where the well-known phenomenon known as "pouring bottle".
- the proposals according to the aforementioned patents are not satisfactory, in particular because the additional means provided on at least one end face of the stopper cause corking difficulties, when the stopper is inserted into the neck of the bottle.
- these means cover the entire end face of the stopper facing the contents of the bottle, it is the material constituting these complementary means which, when the stopper is pressed, after radial compression of the latter, comes into contact with the end of the cervix.
- the material of these additional means being non-compressible, unlike the cork constituting the body of the stopper, these additional means do not undergo the same deformation as the body of the stopper and are thus exposed to alterations such as puckering, cracks, detachments, etc. .
- the corking of a bottle includes a radial compression operation of the cork, with a diameter of 24 mm for a cork for still wine and of 31 mm for a cork for sparkling wine, with a diameter of 15.5 mm, in jaws, the compressed stopper is then pressed into the neck of the bottle where it expands to the inside diameter of the neck, namely 19 mm for a still wine and 17 mm for a sparkling wine.
- this complementary means which first comes into contact with the end of the neck and is stressed to the point of being damaged.
- the material of these complementary means has a high coefficient of friction compared to the glass of the bottle neck, unlike the cork of conventional stoppers which are moreover often treated to improve sliding.
- the present invention relates to a composite stopper overcoming both the drawbacks of the usual cork stoppers made entirely of cork and the drawbacks of the composite stopper according to the aforementioned prior patents.
- the composite stopper, object of the invention, for corking the neck of bottles, in particular of wine bottles, comprises a body made of a compressible material such as cork provided at least at its end facing the content of the bottle of means complementary forming joint.
- the seal means consist of an element of a substantially incompressible elastomer, filling almost completely a cavity of circular section formed in a concentric position in at least one end face of the cap body so that a crown of the face of end of the plug body remains around said cavity, said cavity having a volume such that said element, under the effect of the compression to which the plug body is subjected during plugging, elastically deforms in front of said face end, after capping, so as to establish after capping, in front of said end face of the cap body, a tight seal which covers all of said end face and is in contact with the inside face of the neck of the bottle , thus achieving a total seal against the liquid contained in the bottle.
- the substantially incompressible elastomer element filling the cavity of the end face does not cover the entire end face of the stopper, but on the contrary leaves a crown of cork between its edge outside and the outside edge of the end face.
- This cork wreath allows the bottling operation to take place in the usual way, without modification.
- the relaxation time of the elastomers used being greater than 1 second and the interval between the compression of the caps and the driving in of the caps, on the usual bottling machines, being generally less than 1 second, the elastomer has no time to completely deform, in response to compression of the cap body, before the cap is inserted into the bottle neck. So this is the outer edge of the crown of cork which, at the moment of the insertion of the stopper, comes into contact with the top of the neck of the bottle, so that the conditions of sliding of the stopper in the neck are the same as with fully cork stoppers.
- the closure operation is in no way modified by the presence of the elastomer element on the stopper according to the invention.
- the volume (diameter and depth) of the cavity filled with elastomer is variable, in particular according to the degree of compression of the cork body which varies according to the type of wine to be corked.
- the depth of the cavity corresponds to at least
- the elastomer element is shaped so as to leave, before compression of the plug body, on the end face of the latter, a crown with a (radial) width of at least
- Said cavity may for example have a substantially cylindrical shape, but it may preferably have a divergent shape, that is to say a diameter which increases from the bottom towards its outlet.
- the elastomer constituting the element filling said cavity may preferably be a silicone elastomer, of food grade.
- the elastomer element is formed by molding and crosslinking before it is placed in the cavity, but can also be produced by molding and crosslinking of the raw elastomer in the cavity of the stopper body.
- the elastomer can be constituted by an elastomer permeable to small gas molecules such as H 2 , N 2 , 0 2 , C0 2 , but impermeable to large molecules such as molecules with aromatic rings including those responsible "corky taste".
- the seal formed by the elastomer element does not in any way alter the exchange of gases with small molecules, letting the cork of the cap body alone ensure its role in controlling the usual gas exchange.
- a stopper 1 intended for corking a bottle containing sparkling wine for example Champagne, comprises a stopper body 2 made of natural or agglomerated cork, or a mixture of the two, in the form of a cylinder or a parallelepiped rectangle with rounded edges, having two plane and parallel end faces.
- a circular cavity 3 in the form of a bowl or cap, the edge of the cavity 3 being spaced from the edge of the corresponding end face so that a crown 4 of the flat end face of the stopper body remains around the cavity 3.
- the cavity 3 is filled with a substantially incompressible elastomer 5, for example a silicone elastomer, and this flush with the face of end in the example shown.
- FIG. 2 shows the stopper 1 of FIG. 1 after being inserted into a bottle neck 6.
- the cork stopper 1 is subjected in the usual manner, over the part of its length intended to be pressed into the bottle neck 6 , a radial compression which reduces its diameter from 31 to 15.5 mm. This radial compression is followed, in less than 1 second, by the insertion of the compressed part of the stopper 1 into the neck of the bottle 6.
- the elastomer element 5 which is not compressible undergoes, after a relaxation time of approximately 1 second, therefore after pressing the stopper 1 into the neck of the bottle 6 and re-expansion to the inside diameter of the neck (17 mm) in front of the end face in which the elastomer element 5 is arranged, so that the element 5 adopts, inside the neck of the bottle 6, the shape illustrated in FIG. 2, projecting radially outward on the crown 4 until it touches the inner face of the neck 6, thereby establishing a tight seal over the entire end face of the plug 1.
- the insertion of the stopper 1 into the bottle neck 6 is not modified with respect to the insertion of an entirely cork stopper, insofar as where, during insertion, only the cork of the stopper 1 comes into contact with the glass of the neck 6.
- FIG. 3 illustrates a stopper 11 for still wine, comprising a cork stopper body 12 which comprises, in each end face, a cavity 13a, 13b in the form of a cap or bowl.
- Each cavity 13a, 13b is circular in shape and is formed concentrically in the corresponding end face so as to leave around it a crown 14a, 14b of cork in the plane of the end face.
- Each cavity 13a, 13b is filled with a substantially incompressible elastomer constituting, in the example illustrated, an element 15a, 15b with a convex outer face.
- the cap 1 1 of Figure 3 is pressed into a bottle neck 16 after a radial compression of the cap 1 1 which reduces the diameter of the latter from 24 to 15.5 mm.
- This radial compression that the cork of the stopper body 12 undergoes by elastic compression causes, after a relaxation time of approximately 1 second, an axial deformation of the non-compressible elements 15a, 15b, these two elements 15a, 15b thus adopting the illustrated form. in FIG.
- each element 15a, 15b undergoing, in front of the corresponding end face of the plug body 12 re-expanded to the inside diameter of the neck (17 mm), a radial expansion until it comes into contact with the glass of the neck 16 of the bottle and here constitute a seal tight to the liquid contained in the bottle.
- a circular shaped cavity can be machined directly in the end face of the plug body.
- a cylindrical cavity it is possible, for example in the case a plug body made up of several washers, to hollow out (casing) the last washer and to stick it on the remaining part of the plug body.
- this technique can also be used for a cavity of a shape other than cylindrical.
- the elastomer element can be produced, for example, by molding and crosslinking of "raw" elastomer directly in the cavity, but can also be molded and crosslinked separately to be attached and fixed, for example by gluing or clipping in the cavity.
- the cavity at the point of its outlet, can occupy almost the entire end face of the plug body, but the element allows to remain here, before radial compression of the plug, a crown 4 of width (radial) of at least 1 mm.
- this crown 4 may have a width of between approximately 1 and 2 mm on a still wine stopper of 24 mm in diameter and a width of between approximately 3 and 7 mm on a sparkling wine stopper of 31 mm of diameter.
- the cavity 23 formed concentrically in an end face of the body 22 of a stopper 21, leaving an outer crown 24 of said end face, has a diameter increasing from the bottom towards the outlet of the cavity, so that the cavity has a profile in
- this cavity has flanks which are convex instead of being concave as in the previous examples.
- the cavity 23 has, on its bottom, an annular groove 27 which increases its depth.
- the elastomer element 25 preformed by molding has an outer part 28 in the form of an annular bead which projects beyond the positioning of the element 25 in the cavity 23, at least partly on the end face of the plug body 21 , the central part 29 of the outer face of the elastomer element 25, set back relative to this bead 28, being substantially at the level of the end face (crown 24) of the plug body (front compression of the latter).
- the element 25 is here fixed to the plug body 22 only at the location of the annular rib 30 which it has projecting on its bottom to come to fit in the groove 27 of the cavity 23.
- the element 25 has here, at the place of its part embedded in the cavity 23, therefore subjected to elastic deformation in response to the radial compression of the plug body 22, a smaller diameter than in the previous examples, corresponding at around 50%, or even less, of the diameter of the stopper body before compression, depending on the degree of compression of the stopper.
- the (axial) thickness of the element 25, at the place of its embedded part is greater, being able to be equal to at least 3 mm, for example, for a still wine stopper of 24 mm diameter or for a sparkling wine stopper 31 mm in diameter.
- the elastomer used according to the invention defined as being “substantially incompressible”, is an elastomer which deforms elastically without substantially reducing its volume when it is compressed.
- the reduction in volume of the elastomer is advantageously less than 15%, preferably less than 10%.
- the elastomers capable of being used in the context of the invention it is possible to mention in particular the silicone elastomers vulcanizable under heat (ENC), for example polydimethyl / vinylmethylsiloxane (VMQ), of food quality, capable of be shaped by molding and having a hardness between about 35 and 70 Shore A.
- ENC silicone elastomers vulcanizable under heat
- VMQ polydimethyl / vinylmethylsiloxane
- Successful tests have been performed, for example with a platinum-catalyzed ENC, hardness 60 Shore A, reference S 60 i 59 X, from the company NER ⁇ ERET in LA MOTHE-AUX-AUL ⁇ AIES, F-89120 CHAR ⁇ Y.
