- This device is suitable for occupying - an inactive position in which the diameter of the cap body is less than the inside diameter of the neck and - an active position in which the diameter of the cap body is enlarged to obtain a hermetic seal in the neck of the bottle
- This internal device is adapted to allow the application of a regular pressure on at least one circular line on the internal face of the receiving housing
- the means which make it possible to vary the diameter of the plug body consist, according to a first embodiment, of a bladder provided with inflation and deflation means, preferably in the form of a valve (s)
- a single valve can be used for both inflation and deflation of the bladder, it is also possible to use a first valve for inflation and a second valve for deflation
- the inflation valve is activated when the bottle is closed
- the deflation valve is provided with actuating means which are arranged at the level of the cap head and which are intended to be handled by the user, when uncorking the bottle.
- the means which make it possible to vary the diameter of the plug body consist of a wedge-shaped device, the longitudinal displacement of which ensures the spacing or the constriction of fins which are distributed over the periphery of the housing reception.
- these means adapted to modify the diameter of the plug body consist of an elastically deformable device, actuated by a piston
- At least one elastic stud in the form of a cylinder is provided, threaded on an axis provided with a retaining base.
- This or these cylindrical studs are subjected to the action of a piston which slides on said axis and which is provided with a removable lock for locking in the active compression position of said stud (s).
- This lock is arranged at the level of the cap head so that it can be deactivated by the user.
- the means which allow the evacuation of the compressed gases above the conditioned liquid consist of a pipe arranged in the cap. This pipe makes the connection between the interior volume of the bottle and the outside; it comprises removable closure means, of the valve type (s), provided with actuation means arranged at the level of the plug head.
- these degassing means consist of a pipe which is arranged in the stopper and which makes the connection between the inside volume of the bottle and the outside, which pipe opens into the inside volume of the bottle, at or above the means which allow the diameter of the cap body to be varied
- the internal gases are evacuated when the user performs the operation of reducing the diameter of the plug body.
- the device according to the present invention consists of a cork stopper provided with a blind opening which opens on the top to accommodate the means which make it possible to vary the diameter of its cylindrical body or substantially tapered.
- a cork capsule is advantageously used to close the upper part of this blind orifice and there is advantageously provided a metal muselet for locking the cork stopper on the neck of the bottle.
- the invention also relates to the method of corking and uncorking a bottle using the cork which has just been described.
- This method consists, for capping: a) placing the cork on the neck of the bottle, after conditioning the liquid, b) using the means which make it possible to vary the diameter of the cork body, to increase this diameter with a view to hermetically sealing said bottle, c) possibly placing the metal wire cap, and for uncorking: d) using the means which make it possible to vary the diameter of the cap body to reduce this diameter, e) to evacuate the compressed gases above the conditioned liquid, this operation can be carried out before, during or after operation d), f) if necessary remove the metal wire, before freely removing the cap.

- the various embodiments illustrated in the figures relate to a cork for a bottle of Champagne, the general structure of which is made of cork and which is intended to be locked on the neck of the bottle by a metal wire cap with a cap or an upper cap.
- a metal wire cap with a cap or an upper cap can be envisaged in a material of a different nature, such as plastic, for example; also, the wire cap and the metal cap may, in some cases, not be necessary.
- FIG. 1 The embodiment which is illustrated in Figures 1 to 3 consists of a cork stopper 1 with a cylindrical head 2 extended by a cylindrical body 3 of smaller diameter.
- the head 2 has a diameter which is greater than that of the neck 4 of the bottle while the diameter of the body 3 is slightly lower than that of said neck 4.
- the upper part of the stopper is made of agglomerated cork; the base of the cylindrical body 3 consists of two or three superimposed washers of natural cork.
- the plug head 2 is cut transversely and a cylindrical housing 6 is arranged inside the plug, in said head 2 and in the cylindrical body 3. This housing 6 allows the reception of 'An internal mechanism 8 which is adapted to increase and decrease the diameter of the cylindrical body 3, and to allow the evacuation of the gases which are compressed inside the bottle, present between the conditioned liquid and the cap.
- This internal mechanism 8 ( Figures 1 and 3) consists of an inflatable bladder 10 which is disposed in the housing 6 so that it allows the application of pressure on the internal face thereof, on a at least part of the height of the cylindrical body 3.
- the pressure applied must preferably be regular on at least one circular line of said internal face to ensure a suitable hermetic sealing.
- the inflatable bladder 10 is subjected to the action of a piston valve 13, operable from the outside by a pull tab 14 in the form of a textile or metal tongue.
- the valve 13 has an internal non-return type valve which allows the bladder 10 to be inflated by any suitable means; this valve also allows deflation of the bladder by a deactivation maneuver by means of the pull tab 14.
- a pipe 16 extends from the end of the head 2 to the base of the cylindrical body 3
- This pipe 16 connects the interior volume of the bottle and the exterior; it comprises removable closure means, in the form of a piston valve 17, operable from the outside by the pull tab 18.
- the valve 17 is of the same type as the valve 13 which has just been described.
- the plug head 2 has one or two orifices adapted for the passage of the pulls 14 and 18: this or these orifices are arranged on the above or on the side of the plug head 2, depending on the positioning of the valves 13, 17 and their pull tab 14, 18.
- the bladder 10 and the valves 13, 17 are carried by a support core 20.
- this core 20 consists of a cylindrical part 21 whose base 22 is extended by a axis 23 leading to a base 24.
- the inflatable bladder 10 has a generally cylindrical shape; it is positioned around the axis 23 and it is fixed at one of its ends to the base 22 and at its other end to the base 24.
- This bladder 10 can be made of any suitable material, such as latex or rubber for example. Its attachment to the base 22 and the base 24 can be achieved by any technique ensuring a perfectly hermetic joint (bonding, crimping ).
- the cylindrical part 21 is pierced by a pipe 25 which extends from its upper face to the base 22, inside the bladder 10.
- the upper part of this pipe 25 receives the piston valve 13, secured by screwing for example.
- the support core 20 is integrally traversed by the pipe 16 which extends from the upper face of the part 21 to the base 24 passing through the axis 23.
- the line 16 is extended by a projecting cylindrical part 27 which is intended to be threaded through an orifice 28 arranged in the lower part of the plug body 3.
- the upper part of the pipe 16 receives the piston valve 17, secured by screwing for example.
- the support core 20 can be made in one piece by a plastic injection molding operation.
- the cutting into two parts of the cork stopper, illustrated in FIG. 2, makes it possible to almost entirely hide the internal mechanism 8. After insertion of this mechanism 8 into the orifice 6, the two parts of the stopper are resolidated by bonding. Only the passage opening (s) of the pull tabs 14, 18 are visible. After filling the bottle, the stopper 1 is integrated into the neck 4 in the traditional way. In this inactive position, the diameter of the plug body 3 is less than the diameter of the neck 4 which allows effortless positioning. The bladder 10 is then inflated by means of the valve 13 and the diameter of the cylindrical body 3 increases regularly until the pressure applied to the internal wall of the neck is sufficient to obtain a hermetic seal.
- the wire 30 is placed with the upper capsule 31 so as not to hinder access to the tabs 14 and 18; the whole is covered with a protective and decorative sheet, in aluminum or other.
- the bottle is opened, as illustrated in Figure 4.
- the pull tab 14 is actuated to deflate the bladder 10 and reduce the diameter of the plug body 3, and finally 5)
- the uncorking operation proper consists in removing the plug, this without any effort.
- two different valves are used to operate the inflatable bladder.
- One of the valves is used for inflation, during the capping operation of the bottle; the other valve, fitted with the external pull, is used by the consumer when the bottle is opened.
- FIG. 5 illustrates a substantially different embodiment in which the cork stopper 1 is found with its head 2 and its cylindrical body 3 housed in the neck 4 of the bottle.
- the plug has been shown in the inactive shutter position, without the locking wire.
- the internal mechanism 35 which makes it possible to vary the diameter of the plug body 3 consists of a wedge-shaped device 36 which actuates spacers in the form of radial fins 37.
- the wedge 36 and the fins 37 are housed in a blind orifice 38 which extends on the axis of the plug 1 and which opens into the upper part of the head 2.
- the axial displacement of the wedge 36 downwards causes the spacing of the fins 37 and the diameter of the plug body 3. Its upward displacement causes the tightening of said fins 37 and the reduction of the diameter of the plug body.
- the hermetic sealing of the plug is advantageously carried out by appropriate mechanical means, by moving the wedge 31 downwards and by using a locking system adapted to maintain this position, for example a lock in the shape of a needle or a pin 39 inserted. in an orifice 40 arranged in the plug head and in an orifice 41 arranged in the corner 36.
- the opening is carried out manually before removal of the metal wire cap, by actuating the zipper 42 of the lock 39 and, if necessary, the zipper 43 of the corner 36.
- a degassing pipe connects the internal packaging volume to the outside.
- This pipe can be associated with a valve operable by a pull from the outside, in a similar manner to the previous embodiment illustrated in Figures 1 to 4.
- a simple line 44 without shut-off valve, which opens into the interior volume of the bottle, above or at the level of the means 35 which make it possible to vary the diameter of the cap body.
- the mechanism 35 when the mechanism 35 is activated, the hermetic application of the plug body 3 against the neck 4 prevents the internal gases from escaping.
- these means are deactivated and the diameter of the plug body 3 has been reduced to become less than the diameter of the neck 4, the compressed gases reach said orifice and they naturally escape towards the outside, even before remove the locking wire.
- the muselet presses the head 2 of the stopper against the upper part of the neck 4 and the annular seal 45 thus formed, arranged downstream, does not prevent the evacuation of the gases by the pipe 44.
- this pipe 44 extends in the plug body 3, under the head 2 and perpendicular to the axial orifice 38. It connects said orifice 38 to the internal packaging volume, upstream of the annular seal 45 , but downstream of the compression line or cylinder defined by the mechanism 35 against the internal wall of the neck. The gases are evacuated through this pipe 44 and through the blind hole 38, around the periphery of the corner 36, when the latter is actuated
- FIG. 6 shows this embodiment in the inactive position, that is to say with a minimum plug body diameter.
- the head 2 and the cylindrical body 3 are pierced by a blind axial orifice 50 which extends from the end of head 2 up to, for example, the upper part of the last layer of natural cork
- This hole blind 50 has a generally cylindrical shape and it serves as a housing for an expander mechanism 51 in the form of an elastically deformable device, adapted to allow the diameter of the plug body to be varied over at least part of its height.
- This mechanism 51 consists of an axis 52 provided with a cylindrical base 53 which comes to rest in the bottom of the housing 50.
- the axis 52 has a length shorter than that of the blind housing 50 and it is centered inside this one.
- Two cylindrical studs 55 and 56 of elastic compressible material, rubber type, are threaded on the axis 52, separated by a rigid spacer 57. At rest, the rubber studs 55 and 56 have an external diameter slightly less than the internal diameter of l port 50.
- a piston 58 of generally cylindrical shape, also threaded on the axis 52 and provided with a through orifice 59 slightly offset from its diameter.
- the head 2 of the plug has a practically diametrical orifice 60 which passes right through it, perpendicular to the axis of the blind orifice 50.
- the axis 52 has a peripheral groove 62.
- the axis 52 includes yet another peripheral groove 63. The function of these two grooves 62 and 63 will be explained below.
- a pipe 65 is arranged in the plug head 2, from the orifice 60 to the base of said head 2; this pipe 65 connects the exterior and the interior packaging volume.
- the hermetic sealing of the bottle is carried out by mechanically actuating the piston 58 downward to compress and deform the rubber pads 55 and 56. During this operation, the axis 52 is held in position to avoid deterioration of the part. bottom of the cap.
- the compression operation of the rubber pads 55 and 56 generates a pressure on the internal face of the orifice 50, which pressure makes it possible to increase the diameter of the cylindrical body 3 in order to press the external wall of the latter against the internal face of the neck 4. This compression and the hermetic closure of the bottle are illustrated in FIG. 7.
- a locking lock 66 is inserted in the form of a pin or needle provided with a pull tab or external tongue 67.
- the lock 66 passes through the body of the piston 58 passing through the groove 62 of the axis 52 to ensure effective blocking of the assembly. There is thus obtained a mechanical blocking of the two expanded rubber pads 55 and 56.
- the upper end of the orifice 50 can be closed by a small cork capsule 68 and the metal wire 69 which is adapted to lock the stopper on the neck. of the bottle can be positioned in a conventional manner.
- the uncorking of the bottle is carried out by removing the latch 66 by pulling on the tongue 67.
- the rubber studs 55, 56 resume their "rest” position by their own elasticity and the cylindrical body 3 decreases in diameter.
- the compressed gases above the conditioned liquid reach the orifice 65 and they are evacuated outside by the lateral orifice 60 or by the central blind orifice 50.
- the inner face of the blind hole 50 can be lined with a gas-tight material to avoid the risk of degassing due to possible porosity of the cork used.
- groove 62 can be replaced by a through orifice disposed on the diameter of the axis 52.
- the orifice 60 is provided on the diameter of the plug head and the orifice 58 is arranged on the diameter of the piston 58.
- FIG. 8 shows a possible embodiment of the mechanical device allowing the hermetic sealing by compression of the elastic pads 55 and 56.
- This device consists of a holding jaw 70 whose lower hooks 71 are intended to be inserted into the peripheral groove 63 of the axis 52.
- the jaw 70 is actuated elastically by a slide 72 whose end is intended to apply pressure on the piston 58 in order to ensure the compression of the pads 55 and 56.
- the slide 72 is driven by actuating cylinders 73; during its downward movement to compress the studs 55 and 56, it is supported on a cutaway 74 arranged on the jaws 70 so as to cause the tightening of the hooks 71 in the groove 63.
- the jaws 70 maintain constantly axis 52 during the compression operation of the elastically deformable mechanism.
- this type of stopper can be applied for other types of liquids than Champagne. It can fulfill an effective sealing role for all types of bottles containing sparkling wines, beers, waters, summer ...
