Description
TECHNICAL FIELD

The invention relates to plugs for glass bottles that can be used for automated closure, for long-term preservation of wine and champagne, and for other liquids.

PRIOR KNOWLEDGE

In science and technology different plug designs, intended for closure of glass, plastic and metal bottles, are widely known.

A plug design for bottles used for preservation of wine, consisting of two separate parts in the form of small cups being inserted in each other, at the same time the lower portion is used for hermetic closure of the bottle, the upper portion is made for wedging of the bottom, is known. (Patent EP No 0894730, IPC B65D39/16; 1999). The presented plug serves as an alternative to a cork stopper, its removal from the bottle requires an additional device such as a corkscrew.

A plug design for bottles of sparkling wine (Patent DE No 202006006096, IPC B65D39/00; 2006), which is a rod on which the group of bushes are arranged, at the top of the rod a handle is installed, and in the inner part it has a screwed connection with the rod and a sealing bush with a screwed connection, is also known.

The present plug is intended for holding due to the presence of a long body formed by the bushes. Wedging of the plug happens when the upper handle rotates. The plug design is designated for ensuring of sealing of bottles of sparkling wine without using a metal flange. Design complexity and multiplicity of operations for placing the cork into the bottle does not allow to use this device for long-term preservation of liquids in an industrial environment, and the process of ensuring of hermiticity requires high labor costs.

The closest by the technical nature is the stopper device for repeated closure of bottles (U.S. Pat. No. 3,937,350, IPC B65D39/12; 1976), chosen as a prototype, consisting of a small cup made of elastomer (rubber or caoutchouc), wherein fillers are formed on the small cup, a cap is made in the form of an umbrella and has a connection with a metal rod, the rod size is bigger than the internal cavity of the small cup. This device operates as follows: when the rod moves down, the latter stretches the elastic small cup, the walls of the small cup become thin, and the diameter of the small cup increases, holding the stopper by the inner walls of the bottle. For removing the stopper from the bottle the cap with the rod should be pulled up.

The described device allows to reclose bottles of different types, but it does not provide long-term hermiticity of repeated closure and quality of preservation. The small rubber cup is not designed for extended operation, as the material of the small cup begins to lose its properties in case of long-term stretching and has a low chemical compatibility with food. Elastomers (rubber or caoutchouc) do not provide the necessary rigidity of walls of the small cup, which limits their use in bottles for pressurized beverages. The rod is made of a metal, the extraction of the stopper out of the bottle is carried out only after lifting the rod up. In the described design the type of deformation “tension-compression” is generally used, wherein the thickness of the walls of the small cup varies significantly, which prevents the use of food polymer materials with a low elasticity. In addition, the described device is not designed for automated closure.

DISCLOSURE OF INVENTION

The basis of the presented invention is the creation of a plug for glass bottles providing reliability and simplicity of automated initial closure and repeated closure as well, along with safety of installation and removal of a plug and improvement of storage conditions of a cocked product.

The set problem is solved by means of a plug for glass bottles, containing the upper portion in the form of a cap and the lower portion in the form of a flask with a flange, a rod with guiding members and travel stops providing a given movement of the rod relative to the flask, a button is mounted on the upper end of the rod, a skirt with fillers is formed on the flask, and on the outer side of the flask at least one fixation is arranged in the form of a support, the wall of the flask in the area where the fixations are provided is made of a polymer material with a relatively low elasticity and is capable of deformation like a curve, at least, one pusher and/or, at least, one return cam are formed inside the flask, the rod is equipped with the working member, the latter is made with the possibility of interaction with the pusher and/or with the return cam for providing the interaction between the button and the fixation.

Depending on the stoppered product (wine, sparkling wine, champagne, soda water and other beverages) in the present design of a plug for glass bottles, a cap can have various embodiments, for example, can close the bottle stopper ring from the outer side, or be flat, or in the form of a bottle hood, or rise significantly above the upper cut of the bottle stopper ring, or of any other known form. The cap may be connected with the flask in a rigid or movable way, or be rigidly connected with the flask via the destructible bridges or be performed as a separate component. For bottles of champagne or sparkling wine on the cap an additional area can be made to install a metal flange (muzzle). On the cap a control locking ring can be formed. The cap can be made both of a food polymer and of other materials (metal, glass, etc.).

Guiding elements and travel stops can be made as separate components or be presented by the elements of a flask, rod or cap. Guiding elements and travel stops provide a given rectilinear or curvilinear movement of the rod relative to the flask.

The lower portion of the plug is presented in the form of a flask with a flange. The flange provides the holding of the flask by the upper cup of a bottle. The flask may be presented in the form of a small cup with the bottom of the spherical, flat, concave upward part, with the open lower portion or be of another known form. In the embodiment of the flask with an open bottom portion hermiticity of the connection between the flask and the rod or the button is additionally provided. The flask can be made of a polymer, for example, food grade plastic, polypropylene, polyethylene, nylon or other similar materials. In addition, a gasket providing hermiticity or gas permeability required for wine can be installed in the area where the flange is provided on the flask. Additionally, a gas-permeable filter for providing the process of wine maturation can be fixed in the flask.

To seal the bottle a skirt with fillers which can be placed in the upper portion and/or lower portion of the flask is formed on the flask. The skirt with fillers can be formed as an element of the flask, or as an element of the flange, or as a separate sealing element or by other known method.

The button is connected with the rod in a rigid or a movable way. Embodiments of the button and the rod allow to bring the device into action by pushing the button downward and by its advancement upwards relative to the flask, or when the button turns relative to the flask. The button can be connected with the cap in a rigid or movable way, or can be represented in the form of a cap, or be rigidly connected with the cap via the destructible bridges or be performed as a separate component. In some embodiments the button can have a flexible connection with the cap or the flask, for example in the form of a diagram, corrugation, etc. In the embodiment of the plug with the button and the cap movably connected, for protection against the unauthorized opening an element in the form of the stopper interacting with the button or the cap can be additionally installed.

The rod, installed with the possibility of movement along the guiding elements relative to the flask, gets through the plug. To transfer the impact to the pusher and/or to the return cam the working member is installed preferably in the lower or in the middle portion of the rod. The working member and the rod may be connected to each other in a rigid or in a movable way. Embodiment of the working member may be in the form of a tip, cam, bush, guiding element, movable fork and other similar devices. For providing more elasticity the rod can be formed as a springy element. Depending on the embodiment, the rod can bring the fixations into action when it is uplifted or moving down or rotating relative to the flask. Preferably the working member begins to affect the fixations at the moment of closure of a plug or when it is being removed from the bottle. In addition, between the rod and the flask a spring can be installed.

In the embodiment of the plug, being brought into the action by the way of displacement of the button downwards, a recess for the button is made in the cap. On the outer side of the cap gaps, connected with the recess in which the button is located, may be formed.

Fixations are located on the outer side of the flask in the form of stops, that when interacting with the inner walls of the bottle stopper ring prevent the vertical displacement, and if necessary, the horizontal rotation of the flask as well, thereby ensuring retention of the plug in the bottle. Fixations can be made as a separate component, rigidly attached to the flask, or as part of the flask (for example, the wall of the flask), or in the form of the element movable relatively to the flask, including the form of springy elements, providing additional safety and hermiticity of closure. Fixations kinetically interact with the button. Embodiment of the fixations can be in the form of a cam, ledge, ring around the flask, movable fork, or of another known form.

The walls of the flask in the area where the fixations are provided are capable of deformation like a curve. This is achieved by means of a form or a variable wall thickness of the flask, or by means of making corrugation or grooves on the walls of the flask, or the walls of the flask can be made combined from different materials or by any other known method. In the area where the fixations are provided the form of the flask (along the cross section of the flask) can be varied (for example, in the form of a ring, star, polygon, etc.). Preferably, the wall of the flask in the area where the fixations are provided is made of a polymer material with a relatively low elasticity, when the device operates, thickness of the flask wall can remain virtually unchanged.

In the inner surface of the flask opposite to the area where the fixations are provided, pushers are formed to provide interaction between the rod and the fixations. Under the influence of the working member of the rod on the pushers, the latter hold the fixations in the extended position or transmit the motion to the fixations, which are projecting, that is moving from the center of the flask to the internal walls of the bottle stopper ring. In order to provide greater elasticity the pushers can be formed as springy elements. The pushers can be formed as a separate component or as a part of the flask (for example, the flask wall), or as the element movable relatively to the flask. Embodiment of the pushers can be in the form of a cam, ledge, lobe on the wall, movable fork, or of other known forms.

In the inner surface of the flask, preferably next to the pushers, return cams providing the transfer of the reverse motion from the rod to the fixations may be formed. Under the influence of the working member of the rod on the return cams, fixations are moving toward the center of the flask. Depending on the location of the return cams, the latter provide a direct or indirect effect on the fixations. When return cams are being formed opposite to the area where the fixations are provided, the effect of the rod shifts the return cam and, consequently, the fixation to the center of the flask. When the return cam is being formed on the line of the curve not coinciding with fixation location, the effect of the rod moves the return cam outward to the walls of the bottle stopper ring, and by means of the curve of the flask wall the fixation moves in the opposite direction to the center of the flask. Return cams can be formed as a separate component, or as a part of the flask, or as the element of the pusher, or in the form of the element movable relatively to the flask. In order to provide greater elasticity return cams can be formed as springy elements. Embodiment of the return cams can be in the form of a cam, ledge, lobe on the wall, movable fork, or of other known forms.

The claimed device of a plug for glass bottles operates as follows. In the process of automated closure the pressing machine locates the plug into the bottle stopper ring. A skirt with fillers provides the hermiticity of closure of the contents of the bottle. The rod in its upper portion is connected with the button. The working member of the rod holds the fixations in the extended position outwards via the pushers. Fixations provide holding of the plug in the bottle stopper ring. To remove a plug from a bottle, the button is being sunk in the cavity of the cap, or uplifted, or turned relative to the flask. The impact on the button can be direct or indirect, for example, via the cap having a flexible connection with the button. The rod is displaced along the guiding elements, and ceases to affect the pushers, which allows to curve the wall of the flask and move the fixations towards the center of the flask. Or the rod begins to interact with return cams, which curve flask walls in the area where the fixations are provided and the fixations are being shifted toward the center of the flask. So, holding of the plug in the bottle stopper ring stops. The plug is removed from the bottle at the minimum resistance on the part the skirt with fillers.

Furthermore, the claimed design provides, if necessary, the easy repeated closure of the bottle, as the rod does not hold fixations in the extended position outwards.

The claimed design differs from the prior designs in the facts that:

    • on the outer side of the flask at least one fixation was additionally formed;
    • the fixation was in the form of stops;
    • the flask wall was made in the area where the fixations are provided of a polymer material with a relatively low elasticity;
    • the flask wall was made in the area where the fixations are provided and capable of deformation like a curve;
    • on the inner side of the flask in the area where the fixations are provided at least one pusher was formed;
    • on the inner side of the flask in the area where the fixations are provided at least one return cam was formed;
    • the working member of the rod affects the pusher and/or the return cam for the interaction between the button and the fixation.

Unlike rubber, the materials which can be used for manufacturing of the claimed plug have a low elasticity. In the claimed design of the plug the deformation of “the curve” of flask walls is used, that allows almost not to change the thickness of the walls of the flask in the area where the fixations are provided, providing working efficiency of the claimed design for a new mechanism based on the transfer of movement from the rod to fixations via pushers and/or return cams. The interaction between the rod and the fixation preferably happen at the moment of closure and when the plug is being removed from the bottle. The claimed design of the plug allows to use a wide range of materials providing keeping of beverages in case of long-term preservation, convenience and safety of operation.

FIG. 7 is a design of the claimed plug as claimed in claim 5 in the embodiment of the button rigidly connected with the cap via the destructible bridges. The working member of the rod is in the form of a movable fork. The button is formed and capable of its lowering below the upper level of the bottle stopper ring. The fixation is in the form of a springy element. The upper and the lower portions of the flask are made of different material.

FIG. 8 is a design of the claimed plug as claimed in claim 6 in the embodiment of the cap movably mounted on the flask. The pusher and the return cam are presented in the form of an integrated component. The rod is formed as a moulded member, the stopper is additionally installed.

FIG. 9 is a design of the claimed plug in claim 7 in the embodiment of the fixation in the form of the moving element, return cam and the pusher in the form of an integrated component, the working member in the form of guiding ones, the cap and the button are connected movably.

Claim No 1. FIG. 1-3 are the following elements of the claimed plug: a cap—1; a flask—2; a rod—3; a button—4; a fixation—5; a pusher—6; a return cam—7; a groove—8; a skirt with fillers—9; a gap in the cap—10; an area for the metal flange—11; guiding elements and travel stops—12; a flange of the flask—13; a working member—14 of the rod 3, a recess -15 of the cap 1, destructible bridges between the button and the cap—16.

FIG. 1 is a plug where the fixation 5 is in the extended position. During the automated closure of the plug the walls of the flask 2 curve, a fixation 5 moves to the center of the flask under the effect of the external force, for example, a press, and then opens in a bottle stopper ring. A skirt with fillers 9 provides the hermiticity of the closure, a flange of the flask 13 provides the holding of the plug on the bottle stopper ring.

The flask wall in the area where the fixations are provided 5 is formed of a polymer material with relatively low elasticity. After the removal of the metal flange (for champagne), the plug remains on the bottle stopper ring, as the lower portion of the rod 3 via the working member 14 affects the pusher 6, which, in its turn, affects the fixation 5, holding it in the extended position, not allowing the plug to be removed uncontrollably from the bottle under the effect of excessive pressure.

FIG. 2 is a plug where a fixation 5 is shifted towards the center of a flask. By pushing a button 4, the device is brought into action. The button 4 sinks into a recess 15, bridges 16 are being destructed, a rod 3 moves along rectilinear guiding elements with a travel stop 12, and via a pusher 6 stops affecting the fixation 5. The rod 3 sinks lower and a working member 14 puts pressure on a return cam 7, which curves a wall in a groove 8, shifting the fixation 5 towards the centre of the flask 2. The plug is easily removed under the effect of the excessive pressure in the bottle (for champagne) or a small effort (for beverages without the excessive pressure).

FIG. 3 is a plug where a fixation 5 is shifted towards the center of the flask and a working member 14 of a rod 3 does not affect it. For repeated closure of the plug, via a gap 10 a button 4 is being fixed in the position, when the fixation 5 is not affected. For this purpose the button 4 and, consequently, the rod 3 go up. In such position without a special effort the plug is installed in a bottle stopper ring. For closure of the bottle the button 4 is being shifted down, the rod 3 is being brought into action and the working member 14 affects the fixation 5 via a pusher 6, putting it forward to the bottle stopper ring again and providing a reliable engagement of the plug and the bottle.

Claim No 2. FIG. 4 is the following elements of the claimed plug: a cap—21; a flask with a lower portion curved upwards—22; a rod in the form of a springy element—23; a button in the form of a disk movably installed on the rod—24; a fixation, formed as a separate component—25; a pusher—26; a return cam—27; a skirt with fillers in the form of a ring with fillers, connected with a flange of a flask—28.

For implementation of automated closure, the plug is installed in the bottle stopper ring, and then, after pushing a button 24, a rod 23 is being lowered, and it puts pressure on a pusher 26 and pulls out a fixation 25. For removal of the plug the button 24 and the rod 23 are uplifted, stopping the effect on the pusher 26, the rod puts pressure on a return cam 27, mounted on the flask wall next to the fixation 25. The flask wall becomes deformed and tends to take the form of a ring, which leads to a shift of the fixation 25 to the center of the flask 22. Claim No 3 is similar to claim No 1, differs in the fixation, the return cam, guiding elements, the button and the presence of a gas line filter. FIG. 5 is the following elements of the claimed plug: a fixation—31, represented by the walls of the flask; a return cam of an irregular shape in the form of a lobe on the flask—32 with a springy claw—33 and formed movable relative to the flask; a gas line filter—34, annular guiding elements—35, a working member of the rod—36 in the form of a rod with cavities, a button in the form of a cap 37, permanent movable connection of a button and a flask—38.

A section of the flask provides the holding of the plug in the bottle stopper ring without the rod's effect, pushers are not provided, the connection 38 holds the button on the flask. The rod does not affect the fixation 31. The gas line filter 34 provides the necessary conditions for wine maturation. When the button rotates 37, the rod turns around along the guiding elements 35, the working member 36 puts pressure on the return cam in the form of a movable claw 33 and the lobe 32. Thereafter, the walls of the flask open, pulling the fixations 31, rigidly connected with them, to the center of the flask.

Claim No 4 is similar to claim No 1, differs in the specific embodiment of the button, guiding elements, the pusher, the cap. FIG. 6 is the following elements of the claimed plug: a button—40, a cap made of a metal—41, fixations—42, a pusher in the form of a moving element—43, a support in a flask—44, a rod—45, guiding elements in the form of a screwed connection of a flask and a rod—46, a control locking ring—47, a working member of a rod—48 in the form of a movable lobe, a part of the flask wall in the area where the fixations are provided is made of different material, than the flask—49.

The cap 41 is rigidly fixed on the button 40, the control locking ring 47 is being held by the bottle stopper ring, the movable pusher 43 is installed in the support 44, the fixation 42 is mounted on the wall 49 with other mechanical properties than the material of the flask. The working member 48, affecting the movable pusher 43, pulls out the fixation 42, which provides the closure of the bottle. When the cap 41 rotates, the rod 45 moves along the guiding elements 46 and goes up. The fixations 42 prevent the flask turning, the control locking ring 47 separates from the cap 41. After the button 40 goes up, the rod 45 stops affecting the movable pusher 43 and the fixation 42, that allows to remove the plug from the bottle.

Claim No 5 is similar to claim No 1, differs in the specific embodiment of the button, the rod and the fixation, the flask is made of different materials. FIG. 7 is the following elements of the claimed plug: a spring—50; a button—51, fixations—52, the upper portion of the flask—53 in the area where the fixations are provided 52 is made of a polymer material, food grade plastic is used for this purpose, and the lower portion of the flask—53 is made of a cork tree, the corrugated connection of the flask and the button—54, a return cam is in the form of a flask wall—55, a pusher—56, a working member of the rod is in the form of a movable fork—57 and a stopper—59, a rod—58.

The button 51 via the corrugation 54 is connected with the flask 53. The fixation 52 is in the form of a springy element, a stop 59 affects the pusher 56, which, in its turn, affects the fixation 52, pulling it out. When the button 51 is pushed from top downwards, the curve of the corrugation 54 and the shift of the button 51 below the level of the bottle stopper ring happen. The movable fork 57 turns relative to the rod 58 and begins to affect the return cam 55, and deforms the flask wall by means of its curve. The fixation 52 moves to the center of the flask, providing the removal of the plug from the bottle. A spring 50 returns the fixation 52 to the home position.

Claim No 6 differs from claim No 1 in the specific embodiment of the button, flask and the cap. FIG. 8 is the following elements of the claimed plug: a flask with an open lower portion—60, a button with a serrated joint with a rod—61, a cap with a locking ring—62, a pusher and a return cam in the form of an integrated springy component—63, a screwed connection of a flask and a cap—64, an area of deformation of flask walls in the form of a corrugation—65, a fixation—66, airproof annular guiding elements—67, a working member of a rod—68, a screwed connection of a cap and a button—69, a stopper interacting with a button—70.

The flask is formed with an open lower portion 60, elements 67 provides hermiticity of the plug. The button 61 has a screwed connection 69 with the cap 62. The button 61 in up position is blocked by the stopper 70, and can't revolve about its axis, which doesn't allow to turn the cap 62. The working member 68 is formed as a curved lever. In a closed position the working member 68 pulls out the component 63. Fixations 66 prevent the vertical movement and the horizontal rotation of the flask in the bottle stopper ring. For bringing it into action it is necessary to lower the button 61 down, where it comes out of the engagement with the stopper 70, which allows to turn the cap 62. When turning, the cap 62 moves along the screw 64 and raises up, at the same time the locking ring of the cap 62 comes off, the button 61 moves round a circle due to the connection 69. The cap 62 raises above the button 61, however, continues to rotate the button 61. The button 61 turns the working member 68, which pulls the component 63 to the center. Movement of the component 63 results in the curve of the corrugation 65, which, in its turn, results in the shift of the fixation 66 towards the center of the flask.

Claim No 7 differs from claim No 1 in the specific embodiment of the fixation, button, rod, pusher, return cam, working member and the cap. FIG. 9 is the following elements of the claimed plug: a fixation in the form of a moving element—71, a pusher and a return cam in the form of an integrated component, rigidly connected with the flask wall—72, a working member in the form of guiding elements installed in the lower and middle portions of the rod—73, a cap—74 and a button—75 are movably connected, a skirt with fillers is in the form of a sealing ring—76, flask walls are formed with a tapered thickness—77, a flask—78, permanent movable connection of a cap and a flask—79, bridges between a cap and a flask—80, a screwed connection of a button and a cap—81.

In a closed position a working member 73 affects the component 72, and holds the fixation 71 in the extended position. The sealing ring 76 provides the hermiticity of the closure. When turning, the cap 74 shifts round the circle of the connection 79, the bridges 80 are being destructed, the button 75 along the screw 81 is moving downwards. The working member 73 descends and turns the component 72, thinner walls of the flask 77 near the fixation 71 curve. The fixation 71 turns relative to the flask and moves to the center of the flask. The above mentioned examples of the embodiment of the plug for glass bottles are similar to each other. Other possible examples of designs of the present device come down to obvious combinations of embodiments of fixations, of a button, a rod, a flask and other elements.
