Definitions

• the invention relates to containers for storing carbonated beverages, and in particular single-use cork bottles intended to maintain the taste qualities of the beverage.
• the sparkling drink comes from gases such as carbon dioxide dissolved in the liquid of the drink.
• the dissolved gas can be obtained by fermentation or artificially added.
• the user wants to consume the drink he opens a bottle cap by breaking a seal. After opening, the dissolved gas is gradually released by the liquid.
• many types of bottles have an airtight stopper which, when closed, makes it possible to restrict the gas released inside the bottle, and thus to limit the phenomenon.
• the liberated gas accumulates in the free volume of the bottle, whose pressure increases gradually until stopping the continuation of the gas release phenomenon.
• the pressurized gas accumulated in the free volume, escapes through the neck.
• a part of the gas remained in the liquid volatilizes again, which gradually deteriorates the organoleptic qualities.

• FIG. 5 is a top view of a cap of a fourth bottle variant according to the invention.
• the plug 4 of this variant differs from the plug of the third variant by the presence of an excess thickness 45 in the first wall 48, at the orifice 41.
• This extra thickness 45 advantageously makes it possible to reinforce the plug 4, the orifice 41 having a tendency to 4.
• the plug 4 also comprises two diametrically opposite thicknesses of the wall 48, which facilitate the manual rotation of the cap 4 around the neck 3. These diametrically opposite overthicknesses are advantageously arranged with a radial gap. about 90 ° to orifice 41. These extra thicknesses can make it possible to apply a greater torque, for example to overcome the greater friction torque that can be induced by the presence of certain configurations of the seal 32.
• FIG. 6 illustrates the plug 4 provided with a sealing cap 46.
• the sealing cap 46 is arranged to close the through orifice 41.
• the seal 46 thus makes it possible to prevent an entry of foreign bodies between the stopper and the bottle before it is opened by the user.
• the lid 46 is detachable and may have a projecting gripping tab. It can also remain attached to the cap by one of its sides or its base then acting as a hinge.
• FIG. 7 is a side sectional view of a cap according to a fifth variant of bottle 1.
• This plug 4 differs from the plugs illustrated above by the fact that the orifice 41 is formed in the wall 48.
• the orifice 41 advantageously allows a flow of the beverage downwards. Its configuration simplifies the design of the mold and also promotes demolding.
• Figures 8 and 9 illustrate the operation of a bottle according to the invention to prevent the evacuation of the gas contained in the container 2.
• the operation is illustrated based on the cap shown in Figure 7 but the other variants described have a similar function.
• the bottle is in the flow position in FIG. 8 and in the sealing position in FIG. 9.
• the bottle 1 is placed in a horizontal position or inclined towards the front to allow the beverage to reach the stopper 4.
• the drink can flow between the third wall 44 and the edge 34 of the neck 3.
• the drink can therefore reach the orifice 41 and flow towards outside through this orifice 41.
• the drink is blocked against by the seal 32 and can not flow at the base of the plug 4.
• the outward flow is located at the orifice 41.
• Bottle 1 can be stored horizontally or vertically without generating a gas leak.
• the bottle 1 Before proceeding from the sealing position to the flow position, in order to benefit from the integral conservation function of the residual gas and to preserve the sparkle of the beverage, the bottle 1 is kept sufficiently inclined or horizontal so that the beverage is in contact with the wall 42 of the cap 4. The residual gas is then pushed towards the bottom or to the upper part of the container 2. Thus, when opening the cap, only liquid will flow between the wall 44 and the edge 34 of the neck 3, thus avoiding a new loss of gas. The passage back to the sealing position is achieved by keeping the beverage in contact with the wall 42, to avoid a loss of gas.
• the bottle 1 can be straightened without loss of gas in order to facilitate the screwing of the plug when the internal pressure is below atmospheric pressure, so as to allow a volume of air to enter, balancing the pressures and avoiding a release of the gas still dissolved in the liquid .
• the bottle 1 can be stored in a vertical position without the risk of loss of gas.
• FIG. 10 illustrates a sectional side view of a cap 4 of a sixth bottle variant.
• FIG. 11 is a view from above of this plug 4.
• This plug 4 differs from that of the fifth variant by the presence of a flexible tongue 47, selectively closing the orifice 41.
• the flexible tongue 47 is formed in the wall 48.
• the tongue 47 prevents the penetration of foreign bodies and improve the presentation of the bottle, the presence of the orifice 41 passing unnoticed.
• the flexible tongue 47 further channels the flow of the beverage slightly forward into the flow position.
• the tongue 47 can be obtained by three incisions made by molding or during a subsequent operation (two vertical incisions in the wall 48, joined by a horizontal incision in the wall 42). These incisions act as precursors, so that the user can easily undo the tongue with the nail or a knife tip to rotate it relative to the wall 48.
• the tongue 47 can form a vertical projection relative to the wall 42 to facilitate its grip by the user.
• Tab 47 can be nested in the wall 48 during its closure, by clipping in vertical grooves whose faces form a slightly pinched angle.
• the passage from the sealing position to the flow position is here obtained by rotation of the plug 4. It is possible for the passage from the sealing position to the flow position to be obtained by an opening rotation. about a quarter turn to 3/8 th turn, relative to the maximum tightening position of the cap 4. Different parameters will enable to optimize the sizing of the bottle 1. It may be envisaged that the ring used as a seal has a height at least 1.5 times equal to the axial stroke between the sealing position and the flow position. A ring with a thickness of 2.5 mm (and a width of 1.6 mm with an outer diameter of 27.2 mm) may for example be envisaged, or also a ring in the form of a torus.
• a seal 32 in the form of flange it may have a thickness of about 0.2 mm.
• the collar may have for example an outer diameter of 27 mm for an inside diameter of 26.8 mm of the wall 48.
• the length of the wall 44 will also be defined to provide contact on the desired stroke between the sealing position and the flow position.
• the diameter may be of the order of 4 to 5 mm, ensuring a sufficiently large flow without unduly reducing the structure of the plug 4.
• the dimensions of a rectangular orifice 41, especially in the case of the tongue 47, can measure about 5 mm in height and 4 mm in width.
• the cap has a general shape close to the shape of a mineral water bottle cap according to the state of the art. Therefore, the adaptation of the invention can be done cheaply and on a large scale by modifying a very limited number of characteristics of existing molds.
