    DESCRIPTION

    PLUG AND RETAINING RING ASSEMBLY FOR FOAM WINE TAP

    Field of the invention 5

    The present invention relates to a cap and retaining ring assembly for the production of sparkling wines and the like that can be manufactured with plastic materials and at the same time be used reliably in automatic extraction stations of the cap.
     10
    Background of the invention

    The stopper and retaining ring assemblies for the circulation of sparkling wines and the like are known.

    The cap comprises flexible eyelashes that extend as a perimeter skirt and are intended to externally embrace the upper part of the crown of the bottle. The tabs are provided with internally oriented projections for this purpose and intended to fit into an annular recess of the crown of the bottle so that a retention position is defined.

    In this way, the retaining ring guarantees the blockage of the cap. However, this blockage is effective 20 while the ring is disposed in its proper place in the axial direction, which cannot be any.

    In US Pat. No. 5,813,554 of Marangoni and Cao, a solution of this type is described in which stop means for sliding the ring in the direction of insertion of the ring and in the direction opposite to the direction of insertion are arranged. In this case, the ring insertion stop is constituted by a conical support surface arranged in a step on the periphery of the cover part of the assembly, and a complementary support surface of the ring arranged under a radially oriented projection towards the inside. The sliding stop in the opposite direction is constituted by a projection arranged in the lower part of the ring and oriented inwards, so that in the locked position, it hugs the lower part of the flanges.
     30
    The objective of the aforementioned stop means, in both directions, is that the fixation of the cap in the mouth of the bottle is sufficient to resist the pressures that occur inside during the fermentation process.

    A drawback of this solution is that the contact between the inner surface of the ring and the surface of the cap 35 facing the inner surface of the ring is not total, and there is a gap between them, which can be extended from the insertion stop and the sliding stop in the opposite direction of insertion.

    Another drawback is that the ring has a complex shape, especially because of the presence of corners in the section. 40

    Another drawback of this solution is that the deformations during the plugging process are considerable, since the protrusions occupy an important radial dimension.

    On the other hand, after the fermentation of the sparkling wine, the cap must be removed, an operation that is carried out, in the case of industrial facilities, in automated stations equipped with a wedge that performs a relative reciprocating movement with respect to the bottle for remove the cap. Specifically, the wedge has a reciprocating displacement in an oblique direction with respect to the axis of the bottle, and under normal operating conditions it should only enter with the bottom of the cap, without touching the bottle, and make a run in contact with the cap long enough to overcome the retention force 50 of the ring / cap portion assembly to remove it.

    Therefore, another problem identified by the inventors in known pull caps is that the known plastic plug is not optimal for proper operation of the uncovering wedge, especially since the aforementioned automatic stations are designed to remove caps metallic, whose height of outer skirt 55 is very reduced. Most especially, in this sector a minimum cap removal failure rate is demanded.

    A possible solution would be to adapt these stations to the shape of plastic pull caps made of two parts, but this implies high costs and little versatility of the stations. 60

    Description of the invention

    To overcome the aforementioned drawbacks, the present invention proposes a stopper and retaining ring assembly for the circulation of sparkling wines, configured to be applied to a bottle with a crown having an upper part and an annular recess below the upper part, in which the cap comprises a part of
    lid and a plurality of flexible flanges extending from the lid part as a perimeter skirt intended to externally embrace the upper part of the crown of the bottle, the flanges provided with projections radially oriented inwardly and intended to fit into the annular recess in a retaining configuration of the assembly in the bottle, the retaining ring intended to slide axially along the outer surface of the flanges according to the axial direction of the cap to embrace the cap and 5 externally press the flanges against the crown of the bottle so that the projections fit into the annular recess, and in which, in the retention configuration there is no space between the surface of the retaining ring facing the flanges and the surface of the flanges facing said ring surface.

    In this way, the fastening of the eyelashes by the retaining ring is optimal, since no space is left for the deformation of the eyelashes. In addition, this feature allows to obtain a more compact set and with greater resistance performance.

    In the following description, when the terms 'upper' and 'lower' are used in relation to a part or a component it should be understood that the first is closer to the mouth of the bottle, and the second closer to the bottom of the bottle, when the set is applied to the bottle.

    In some embodiments, the set comprises:

    - first stop means for blocking in the retention configuration the sliding of the retaining ring by the plug in the axial direction and in the direction of insertion of the retaining ring and
    - second stop means for blocking in the retention configuration the sliding of the retaining ring through the plug in the axial direction and in the opposite direction to the introduction of the retaining ring.
     25
    With these characteristics, there is a set that can be positioned correctly and by means of a simple axial thrust operation in the retention configuration, that is, the configuration with the protrusions of the flexible tabs in the annular recess and without the possibility of leaving given that the retaining ring embraces the flanges from the outside and does not allow its expansion and in which the blocking of the flanges is optimal, since its deformation is not allowed at any point on the surface embraced by the inner surface of the retaining ring. 30

    In some embodiments, the retaining ring has a tetragonal section so that an internal cylindrical pressure surface is defined against the plug in the retention configuration, an external surface opposite the internal cylindrical surface, an upper circular crown intended to be pressed by a locking tool of the cap-retaining ring assembly and a lower circular crown intended to be pressed by an uncovering tool.

    This retaining ring configuration makes it possible to have a solid and simple low-cost part, contrary to the solution disclosed in the aforementioned American patent. This retaining ring allows the assembly to be arranged in its retention configuration through a simple and easy to automate operation. 40 Likewise, the ring can be removed at an automated degolling station.

    In some embodiments, each of the stop means is constituted by a support zone belonging to the retaining ring and a support zone belonging to the stopper, the support areas being complementary in the retention configuration, the support areas having the ring a part adjacent to the internal cylindrical surface 45.

    By providing that the support areas are adjacent to the internal cylindrical surface, the support is optimized, as this occurs in areas of intimate contact between ring and plug, in particular areas more difficult to deform than any other part of the ring. In particular, the only areas that are specifically molded to make the support are the interior ones, the remainder being solid, which confers greater resistance and rigidity to the ring, which is responsible for resisting the high pressures that will occur on the plug in the second fermentation process of sparkling wine. This allows, therefore, to optimize the ratio of the dimensions of the ring / resistance and therefore more freedom in reducing the height of the ring, with a view to allowing a correct operation of the uncovering wedge. 55

    In some embodiments, the surface of the flanges facing the inner cylindrical surface of the retaining ring has a complementary cylindrical shell of the inner cylindrical surface of the retaining ring.

    In this way, the relative sliding between cap and retaining ring during the operation of applying the assembly to a bottle is not impeded by obstacles and implies minimal deformation of the parts.

    In especially preferred embodiments, the support zones belonging to the ring and the support zones belonging to the cap are arranged, when the assembly is arranged in the retention configuration, at the intersection between the internal cylindrical surface and the upper circular crown. 65

    This arrangement allows the first stop means to be concentrated in an elevated area of the ring, specifically in the area that will be the last to fit, so that the entire inner surface of the ring will easily slide to the retention configuration. In particular, the ring will barely deform, which will allow you to press the tabs correctly.
     5
    In some embodiments, the first stop means are constituted by:

    - projections in the retaining ring oriented towards the stopper in the retention configuration, the projections extending perimetrically as circle arcs evenly distributed along the intersection between the internal cylindrical surface and the upper circular crown; and 10
    - complementary recesses in the cap, in the retention configuration, to the projections.

    This solution has proved to be very effective because, in addition to having the introduction stop means, it also allows to avoid a relative rotation movement between ring and plug.
     fifteen
    In some embodiments, the second stop means are constituted by projections of the cover part evenly distributed on the periphery of the cover part, the cover projections being each provided with a support surface and the projection projections being arranged. so that in the retention configuration they are positioned along the intersection between the internal cylindrical surface and the upper circular crown of the retaining ring with the bearing surfaces facing the upper circular crown. twenty

    In this way, the upper circular crown is used as a support area.

    In some embodiments, the projections of the ring are three, the projections of the cover part are three, with the projections of the ring and the cover part alternated. 25

    In some embodiments, the first stop means comprise outer projections at a lower end of the tabs and corresponding recesses in the retaining ring.

    In other embodiments, the first stop means comprise a perimeter projection on the inner cylindrical surface 30 of the ring or on the outer surface of the flanges, the outer surface of the flanges or the ring being provided with a groove complementary to the protrusion.

    In some embodiments of the assembly, in the retention configuration, the lower ends of the tabs do not protrude from the retaining ring by more than 1 mm in the axial direction. 35

    By not protruding the end of the eyelashes from the bottom, the shredding wedge finds no impediment which facilitates the removal of the cap.

    In other embodiments, in the retention configuration, the lower ends of the tabs are at the same level as the lower circular crown in the axial direction.

    The benefits sought are optimized by means of the dimensioning of the lower part of the tabs.
     Four. Five
    In all embodiments, it is preferred that the retaining ring and the cap portion be made of polyethylene.

    Polyethylene is a material with a stiffness and strength suitable for the whole.

    In some embodiments, the inner surface of the lid has a circular crown of support on the lip of the bottle, the distance between the circular crown and the lower end of the flanges being between 7 and 10 mm.

    According to this characteristic, a reduction in the failure rate can be achieved during the degolling process. As is known, the slaughter stations have standardized dimensions, in accordance with the usual dimensions of the set formed by the sparkling wine bottle and the cap. This range of preferred dimensions allows both to have an effective retention of the plug during the second fermentation process and to leave the minimum space required by the wedge of the automatic degolling station to minimize the rate of degolling failures.
     60
    According to other embodiments, the upper surface of the lid part is flat, and the lower surface of the lid part is provided with radial ribs.

    This combination of features allows simultaneously to give resistance to the cap, to resist high pressures, and to have a flat surface for printing data related to the traceability of the bottle in question.
    According to some embodiments, the cap portion is extended from its bottom surface by a tubular protuberance of a diameter greater than the internal diameter of the crown of the bottle so that the outer surface of the protuberance presses the inner surface of the crown of the bottle when The cap is applied to the bottle.
     5
    In this way, the sealing of the plug is increased, reducing the chances of gas or wine leakage due to increased pressure.

    According to a particularly preferred embodiment, the maximum outer diameter of the retaining ring is 35.8 mm. 10

    The inventors have been able to verify that this maximum dimension allows both minimum dimensions of the ring to withstand the high pressures produced and, on the other hand, it is compatible with the dimensions of the holes found in the automated plugging and slaying stations.
     fifteen
    In some embodiments, the outer surface of the retaining ring is a cone section, the outer diameter of the upper circular crown being less than the outer diameter of the lower circular crown.

    This feature helps to avoid failures in the operation of inserting the neck of the bottle in the degolling station. twenty

    In especially preferred embodiments, the cap and the retaining ring are joined by a plurality of frangible pins attached to the retaining ring at the intersection between the inner cylindrical surface and the lower circular crown and the upper perimeter edge of the cap.
     25
    Therefore, the pins allow the precise relative positioning of the two parts of the assembly prior to the capping operation, as well as manipulating the assembly as a single piece before plugging.

    Preferably, the frangible pins are arranged coinciding, according to the longitudinal direction of the assembly, with the space between tabs. 30

    Thus, when the capping operation is performed, the pins do not interfere with the tabs.

    Description of an embodiment of the invention

    As can be seen in the figures, the invention generally refers to a set 1 of stopper 2 10 and retaining ring 3 for the circulation of sparkling wines, configured to be applied to a bottle B with a crown having a top part and an annular recess A below the top.

    As can be seen in FIGS. 7 and 8, the plug 2 comprises a cover part 21 and a plurality of flexible flanges 4 extending from the cover part 21 as a perimeter skirt intended to externally embrace the upper part of the crown of the bottle B, the flanges 4 being provided with projections 5 oriented radially inwardly and intended to fit into the annular recess A in a retention configuration of the assembly 1 in the bottle B.

    To lock the cap at the mouth of the bottle, the retaining ring 3 must slide axially by 20 the outer surface of the flanges 4 according to the axial direction of the cap 2, to embrace the cap 2 and externally press the flanges 4 against the crown of the bottle B so that the projections 5 fit into the annular recess A. This retention or locking configuration is illustrated, for example, in the section of Figure 7.
     25
    As can be seen in the figures, in the retention configuration there is no space between the surface of the retaining ring 3 facing the flanges 4 and the surface of the flanges 4 facing said surface of the ring 3.

    As can be seen in the figures, the set comprises: 30

    - first stop means 11, 12, 25, 27, 35 to block in the retention configuration the sliding of the retaining ring 3 by the plug 2 in the axial direction and in the direction of insertion of the retaining ring 3 and
    - second stop means 11, 12, 26, 33 to block in the retention configuration the slide 35 of the retaining ring 3 by the plug 2 in the axial direction and in the opposite direction to the introduction of the retaining ring 3.

    As can be seen in Figures 4 and 7, the retaining ring 3 has a tetragonal section so that an internal cylindrical surface 32 is pressed against the plug 2 in the retention configuration and the flange surface oriented towards the Internal cylindrical surface 32 of retaining ring 3 has a complementary cylindrical shell of internal cylindrical surface 32 of retaining ring 3.

    The ring also comprises an outer surface 31 opposite the inner cylindrical surface 32, an upper circular crown 33 intended to be pressed by a locking tool of the stopper-ring assembly 45 and a lower circular crown 34 intended to be pressed by a uncover tool, such as a wedge that has an oblique swaying motion. The effect of the uncovering tool, which has an oblique impact, is not only to move the retaining ring in the opposite direction to the blocking one, but to remove the entire assembly.
     fifty
    It should be noted that this approximate shape of a section of tube of the retaining ring is of simple manufacture and is optimal when working as a compression or encircling element of the eyelashes.

    In preferred embodiments, each of the stop means is constituted by a support zone belonging to the retaining ring 3 and a support zone belonging to the stopper 2, the support zones 55 being complementary in the retention configuration and in particular , the support areas of the ring have a part adjacent to the internal cylindrical surface 32.

    As can be seen in Figures 6 to 10, the support areas belonging to the ring and the support areas belonging to the cap are arranged, when the assembly 1 is arranged in the retention configuration, 60 at the intersection between the internal cylindrical surface 32 and the upper circular crown 33.

    In an especially preferred embodiment, illustrated in Figures 3, 5, 6, 7, 8, 9, 10 and 11 the first stop means are constituted by:
     65
    - projections 35 in the retaining ring 3 oriented towards the plug in the retention configuration,
    the projections 35 extending perimetrically as circle arcs evenly distributed along the intersection between the internal cylindrical surface 32 and the upper circular crown 33; Y
    - recesses 25 in the plug 2 complementary, in the retention configuration, to the projections 35.

    On the other hand, in this especially preferred embodiment, the second stop means are constituted by 5 projections 26 of the cover part 21 evenly distributed on the periphery of the cover part 21, as shown for example in Figures 8 and 10. In particular, the projections 26 of the cover 21 are each provided with a bearing surface 22 and are arranged so that in the retention configuration they are positioned along the intersection between the internal cylindrical surface 32 and the upper circular crown 33 of the retaining ring 3 with the bearing surfaces facing the upper circular crown 33, so that it works as the bearing surface of the ring.

    As can be seen in FIG. 10, the protrusions 35 of the ring are three, the protrusions 21 of the lid part are three, the protrusions of the ring and the lid part alternated.
     fifteen
    According to another embodiment, the first stop means comprises outer projections 27 at a lower end of the tabs 4 and corresponding recesses in the retaining ring 3. In this embodiment, the stop seconds can be provided as shown in the Figures 3 or 4

    According to other embodiments, illustrated in Figures 13 and 14, the first stop means comprise a perimeter shoulder 20, 12 on the inner cylindrical surface 32 of the ring 3 or on the outer surface of the flanges 4, the outer surface being of the tabs 4 or of the ring 3 provided with a groove complementary to the projection 11, 12.

    In all embodiments, it is preferred that, in the retention configuration, the lower ends of the 25 tabs 4 do not protrude from the retaining ring 3 by more than 1 mm in the axial direction or that they are at the same level of the ring, for do not interfere with the trajectory of the shredding wedge, since the inventors have been able to verify that the plug assemblies of this type in which the ring or in the eyelashes extend too far down, lead to failures in the removal of the draw plug .
     30
    The inner surface of the lid 21 has a circular crown 23 supporting the lip of the bottle B, whose edges are preferably adapted to the curvature of the edges of the lip of the bottle.

    On the other hand, the inventors have been able to verify that when the distance between the circular crown 23 and the lower end of the flanges 4 is between 7 and 10 mm, the error rate in the slag stage is very small, when this The process is carried out in slaughter stations with standardized dimensions, in accordance with the usual dimensions of the set formed by the sparkling wine bottle and the stopper.

    As can be seen in the profile sections, the upper surface of the lid part 21 is flat, which facilitates the printing of tracking codes of the bottle B. So that the flat part can withstand pressures, both internally by the Liquid gas, as external, by the code printing tool, the bottom surface of the lid part is provided with radial ribs 28, as shown in Figure 11.

    As shown for example in Figures 8 and 9, the cover portion 21 is extended from its lower surface 45 by a tubular protuberance 24.

    This tubular protrusion or cylindrical fence is intended to press the inner surface of the mouth of the bottle to help ensure tightness. For this, the outer diameter of this protuberance 24 must be greater than a fraction of a millimeter, enough to be able to introduce the protuberance into the mouth of the bottle, to the internal diameter of the crown of the bottle B.

    It is also known that in the process of uncovering or degolling, the mouth of the bottle, where the assembly is fixed, must be introduced through a hole in the degolling station that has a standard diameter. In particular, it has been possible to determine that the maximum diameter that allows to practically cancel the failure rate is 55 of 35.8 mm.

    Further reducing the failure rate at the slaughter station may contribute that the outer surface 31 of the retaining ring 3 is a cone section, and that the outer diameter of the upper circular crown 33 is smaller than the outer diameter of the crown lower circular 34. 60

    The assembly of the invention is designed to be molded from a plastic material, and as it is constituted by two parts, it is necessary to reduce manufacturing costs and to provide a positioning prior to the plugging stage that the two parts, plug 2 and ring 3, be molded together.
     65
    To do this, when leaving molded, the plug 2 and the retaining ring 3 are joined by a plurality of
    frangible pins 41 attached to the retaining ring at the intersection between the internal cylindrical surface 32 and the lower circular crown 34 and the upper perimeter edge of the lid 21. This arrangement is shown in Figures 8 and 9.

    Finally, the frangible pins 41 are arranged coinciding, according to the longitudinal direction of the assembly 5 1, with the space between tabs 4, so as not to interfere with the tabs when the ring slides on the outside of these to perform the capping, as is shown for example in Figure 7, which shows two pins 41 on each side, arranged adjacent to the side seen from the tabs.

    In this text, the word “comprises” and its variants should not be interpreted in an exclusive way, that is, no 10 excludes the possibility that the described includes other elements.

    On the other hand, the invention is not limited to the specific embodiments that have been described but also covers, for example, the variants that can be made by the average person skilled in the art, within what follows from the claims. fifteen
