    [0002] Capping device intended to be attached to the neck of a container
    [0004] Technical field
    [0006] The invention relates to an assembly comprising a container and a capping device that is equipped with a cap and allows said cap to be kept fixed to the neck of a container, thus avoiding losing the cap altogether.
    [0008] Technological background
    [0010] Document ES1232089U discloses a capping device that includes a lower ring intended to be axially fixed on the neck of a container, a cap that includes a thread intended to engage a complementary thread formed in the neck of the container and a hinge that joins the cap with the bottom ring. The lower ring includes latching means provided to retain the lower ring with the neck of the container. The section of the diameter of the lower ring in which there are hooking means extends between 25 and 75% of the diameter of the lower ring. The section of the lower ring that is connected to the cap by the hinge device lacks engagement means which allows said section to rotate between a lowered position and a raised position, in particular, to allow the cap to unscrew. On the other hand, the cap includes ratcheting means intended to cooperate with the complementary ratcheting means formed in the lower ring and thus allows the cap to be held in a tilted open position.
    [0012] This capping device is not completely satisfactory. Indeed, despite the absence of latching means in the section of the lower ring that is connected to the cap by the hinge, the manipulations of the cap to allow the section of the lower ring that is connected to the cap to rotate towards a raised position when The plug must move from the tilted open position to the closed position are not easy.
    [0014] Summary
    [0016] An underlying idea of the invention consists in proposing a capping device that allows keeping a stopper attached to the neck of the container that is reliable, easy to make and use.

    [0019] - a plug including an upper wall and an external peripheral skirt, the external peripheral skirt having a helical thread intended to cooperate with a helical thread formed in the neck to allow:
    [0021] • an unscrewing of the plug from the neck about an axis X to move the plug from a closing position in which the upper wall closes the hole in the neck and the peripheral skirt surrounds said neck to a released position in which the plug no longer it is coupled with the neck; Y
    [0022] • screwing the cap into the neck to move the cap from the released position to the closed position;
    [0024] - a lower ring fixed axially to the neck and movable in rotation on the neck about said axis X, said lower ring including a first sector that includes hooking elements that project radially towards the interior of the lower ring and are intended to be arranged below of the engagement collar to axially retain the lower ring on the neck of the container, the first sector and the second sector of the lower ring are hinged together so that the second sector rotates with respect to the first sector between a lowered position in which the second sector is adapted to be arranged below the hooking collar and a raised position in which the second sector is adapted to be arranged at least partially above the hooking collar;
    [0025] - an articulation device that joins the cap to the second sector of the lower ring and is configured to allow the cap to rotate between the released position and an open tilted position in which the cap is disengaged from the hole in the neck, the articulation device is it extends over a first angular interval that is cut into two equal parts by a bisector plane Pb;
    [0026] - the lower ring is configured so that the second sector rotates with respect to the first sector from the lowered position to the raised position to allow the cap to move from the closed position to the released position;
    [0027] - the lower ring can move radially from front to back to facilitate the passage of a part of the second sector on each side of the hooking collar during the movement of the second sector between the lowered position and the released position, the helical thread developing around the axis X according to a first direction and having a lower end and an upper end, the lower end of the helical thread is arranged in a second angular interval which is defined between the bisector plane Pb and a radial plane positioned at 160 ° of the bisector plane Pb according to a second direction opposite to the first direction.
    [0029] This facilitates engagement of the cap on the neck when the cap is moved from the tilted open position to the closed position.

    [0033] According to one embodiment, the lower end of the helical thread is arranged in an angular interval defined between two radial planes, respectively, positioned at 90 ° and 160 ° from the bisector plane Pb according to the second direction of rotation.
    [0035] According to one embodiment, the first sector of the lower ring includes a front zone that is diametrically opposite to the second sector and two hooking zones that are each arranged between the front zone of the first sector and the second sector, the hooking elements are arranged only in the two engagement areas to allow radial movement of the lower ring. In this way, the traction forces that will be exerted on the lower ring to allow the second sector to move between the lowered position and the raised position are less, which facilitates the use of the capping device.
    [0037] According to one embodiment, the front zone of the second sector extends over an angular range comprised between 90 and 150 °.
    [0039] According to one embodiment, each of the two hooking areas extends over an angular range of between 30 and 90 °.

This makes it possible to further facilitate the use of the capping device, in particular when the cap must be moved from the tilted open position towards the closed position.
    [0052] According to one embodiment, the stopper is configured so that, during the movement of the cap from the released position to the tilted open position, the stopper rests against an upper end of the second sector of the lower ring to move it from the raised position towards the lowered position. This also makes it easier to use the capping device.
    [0054] According to one embodiment, the locking device further includes a bead that is formed in the outer peripheral skirt of the cap and extends axially, the bead being configured to bear against a helical rib of the helical thread formed in the neck of the container during movement of the plug from the tilted open position to the released position to exert a pulling force on the second sector having a component directed radially outward and a component directed axially upward to aid movement of the second sector from the lowered position toward the raised position.
    [0056] According to one embodiment, the stop protrudes radially outward from the bead.
    [0057] According to one embodiment, the articulation device includes two blades and the heel is formed between the two blades.
    [0059] According to one embodiment, the articulation device includes two blades and the plugging device also includes a device for locking the plug in the tilted open position, said locking device including a stop that is formed on the outer peripheral skirt, between the two blades of the hinge device, and which is configured to abut against the neck of the container when the cap is in the tilted open position, the butt has an internal face on which at least one rib of the helical thread is formed. This makes it possible to improve the pressure resistance of the capping device.

    [0088] Detailed description of the embodiments
    [0090] In the description and the figures, the axis X corresponds to the axis of rotation of the cap 1 of the capping device when it is screwed onto the neck 2 of the container. By convention, the "radial" orientation is directed orthogonal to the X axis and the axial orientation is directed parallel to the X axis. The terms "external" and "internal" are used to define the relative position of one element with respect to another, for With reference to the X axis, an element close to the X axis is thus classified as internal as opposed to an external element located radially on the periphery.
    [0092] The terms "upper" and "lower" are used to define the relative position of one element with respect to another by reference to a position in which the hole 3 of the neck 2 is oriented upwards and the cap 1 is in the closed position. in the neck 2 of the container, being called, an element destined to be placed lower, lower and being called, an element destined to be placed higher, upper. The terms "in front" and "behind" are used to define the relative position of one element with respect to another along a diameter perpendicular to the X axis.
    [0094] With reference to Figures 1 to 10, an assembly is described below comprising a capping device, represented, in particular, in Figure 1, and a container equipped with a neck 2, represented, in particular, in Figure 2.
    [0096] As shown in figure 2, the neck 2 of the container has an upper end in which a hole 3 is formed which allows the contents of the container to be poured. The neck 2 of the container includes a support collar 4 projecting radially outward and a latch collar 5 also projecting radially outward and which is arranged axially between the support collar 4 and the hole 3. A portion cylindrical is axially formed between the support collar 4 and the hole 3. On the other hand, the neck 2 includes, positioned axially between the hooking collar 5 and the hole 3, a helical thread 6 formed by a series of helical ribs, projecting radially outward from an external surface of the neck 2. The helical thread 6 is adapted to cooperate with a complementary helical thread 7 formed from a series of helical ribs that are formed in the cap 1 of the cap device.
    [0098] According to one embodiment, the helical thread 6 formed in the neck 2, as well as the helical thread 7 formed in the cap 1 are interrupted. In other words, the adjacent helical ribs are separated by a space that forms a vent and that allows, in particular, to evacuate the gas present inside the container while the cap 1 is still fitted in the neck 2.
    [0100] The plugging device includes a lower ring 9 that is retained in the neck 2 of the container, a plug 1 that is intended to cover the hole 3 of the container in order to seal it, a hinge device 10 that joins the plug 1 with the lower ring 9 and a locking device positioned to lock the cap 1 in a tilted open position, shown in Figures 4, 9 and 11. In the tilted open position, the cap 1 is disengaged from the hole 3 of the container and does not obstruct the discharge of the contents of the container.
    [0102] As illustrated in Figures 7 and 8, the articulation device 10 extends over an angular interval S1 which is cut into two equal parts by a vertical bisector plane Pb.
    [0103] Returning to Figure 1, it is observed that the cap 1 includes an upper wall 13 intended to be arranged substantially and orthogonally to the axis X, opposite the hole 3 of the neck 2 when said cap 1 is in the closed position. The cap 1 further includes an outer peripheral skirt 14 intended to surround the neck 2 of the container when the cap 1 is in the closed position. The outer peripheral skirt 14 extends, downward, perpendicular to the upper wall 13, from the outer periphery of said upper wall 13.
    [0105] The outer peripheral skirt 14 has, on its inner face, a helical thread 7, visible in Figures 2 and 5 to 7, formed by a series of helical ribs that extend around the axis X in a first direction of rotation. The helical thread 7 is intended to cooperate with the helical thread 6 formed on the external surface of the neck 2. In this way, the cap 1 is able to screw into the neck 2 in order to close the container and to unscrew from the neck 2 in order to open the container. The cap 1 can thus be moved between a closed position and a released position, shown in figure 3. In said released position, the cap 1 is no longer engaged with the neck 2. Therefore, it is capable of tilting towards the tilted open position, represented in Figures 4, 9 and 11, in which the cap 1 is disengaged from the hole 3 of the neck 2 so as not to hinder the pouring of the contents of the container.
    [0107] As shown in particular in Figure 9, the plug 1 also includes an inner skirt 8, which extends perpendicularly downward from the upper wall 13 of the plug 1 and is dimensioned to be inserted into the hole 3 of the neck 2. The Plug 1 also includes an annular lip 15 extending, from the upper wall 13, radially between the inner skirt 8 and the outer peripheral skirt 14. The inner skirt 8 and the annular lip 15 are dimensioned so that, when the plug 1 is in the closed position, in the neck 2 of the container, the inner skirt 8 is in contact against the inner face of the neck 2 while the annular lip 15 is in contact against the outer face of the neck 2. In this way, the skirt internal 8 and the annular lip 15 make it possible to guarantee the sealing of the closure.
    [0109] Advantageously, the lower ring 9 is, before the first opening of the container, connected to the cap 1 by frangible bridges, not visible in the figures, intended to break during the opening of the cap 1. These frangible bridges thus constitute some seals of inviolability.
    [0111] The lower ring 9 is held axially on the neck 2 of the container while it can rotate with respect to it about the X-axis. As shown in figure 3, the lower ring 9 includes two parts that are articulated to each other, that is, a first sector 16 and a second sector 17 by which the lower ring 9 is connected to the plug 1 by means of the articulation device 10.
    [0113] According to one embodiment, the lower ring 9 includes two narrowed areas, that is, the radial thickness of which is less than the radial thickness of the lower ring 9 outside of said narrowed areas. The two narrowed areas delimit the first sector 16 and the second sector 17. The narrowed areas thus form pivots that allow the second sector 17 to articulate with respect to the first sector 16.
    [0115] According to another embodiment, the lower ring 9 does not have narrowed areas that delimit the first and second sectors 16, 17.
    [0117] The second sector 17 is able to rotate upwards with respect to the first sector 16, between a lowered position in which the second sector 17 is intended to be arranged under the hooking collar 5 and a raised position, in which the second sector 17 is arranged at least in part above the hooking collar 5. This allows the cap 1 to move up with respect to the neck 2 of the container, until the helical thread 7 of the cap 1 disengages from the helical thread 6 formed in the neck 2 of the container. In other words, when the cap 1 is unscrewed, the lower ring 9 is driven in rotation around the X axis while the second sector 17 of the lower ring 9 rotates with respect to the first sector 16 to the raised position to allow axial movement, upward of the cap 1, from the closed position, to the released position, shown in figure 3. When the cap 1 rotates from the released position to the tilted open position, the second sector 17 of the lower ring 9 rotates in the direction opposite to the first sector 16 and then returns to the lowered position. On the other hand, as described in more detail below, the second sector 17 also rotates relative to the first sector 16 from the lowered position to the raised position when the cap 1 rotates from the tilted open position to the released position.
    [0119] The lower ring 9 is held axially on the neck 2 of the container by means of the hooking collar 5, in particular, visible in Figures 5 to 7. The hooking collar 5 has a frusto-conical external surface that tapers upwards, that is to say , towards hole 3 of the container. The hooking collar 5 delimits, downwards, that is to say, in a direction opposite to the hole 3, a projection. The first sector 16 of the lower ring 9 includes hooking elements 18 that cooperate with the hooking collar 5 formed in the container in order to axially retain the lower ring 9 to the neck 2 of the container. The hooking elements 18 are protrusions, represented in particular detail in Figures 5 and 6, projecting radially inward from the first sector 16 of the lower ring 9. The retaining elements 18 have an increasing radial dimension, from below upwards, that is, towards the upper edge of the lower ring 9. During the assembly of the capping device on the neck 2 of the container, the hooking elements 18 slide against the frusto-conical surface of the hooking collar 5 and then lock by means of an elastic return behind the coupling collar 5.
    [0121] As shown in Figures 5 and 6, the first sector 16 of the lower ring 9 includes a front zone 19 that is diametrically opposite to the second sector 17 of the lower ring 9 and two engagement zones 20, 21 that are arranged on each side of the front zone 19 and are each arranged between the front zone 19 and the second sector 17 of the lower ring 9. The hooking elements 18 are only arranged in the two hooking zones 20, 21. Thus, due to the absence of hooking elements 18 in the front area of the first sector 16, there is a radial space between the lower ring 9 and the neck 2 that allows the lower ring 9 to move from front to back and vice versa. The radial clearance between the lower ring 9 and the neck 2 in the front / rear direction is, for example, between 0.5 and 1 mm. This facilitates the passage of a part of the second sector 17 on either side of the latch collar 5 during the movement of the second sector 17 between the lowered position and the raised position. In other words, the traction forces that will be exerted on the lower ring 9 to allow the second sector 17 to pass on each side of the latch collar 5 are less.
    [0123] Advantageously, the second sector 17 extends over an angular range comprised between 90 and 150 °, and for example, of the order of 120 °, the front area of the second sector 16 extends over an angular range comprised between 90 and 150 ° , for example, of the order of 120 °, while each of the two engagement zones 20, 21 extends over an angular range comprised between 30 and 90 °, for example, of the order of 60 °.
    [0124] On the other hand, the bisector plane Pb cuts into two equal parts the second sector 17, as well as the front part of the second sector 17. The angular intervals corresponding to the two engagement zones 20, 21 are therefore symmetrical with each other. with respect to the bisector plane Pb.
    [0126] The articulation device 10 is configured to allow the cap 1 to rotate between the released position, shown in Figure 3, in which the outer peripheral skirt 14 is extends downwardly from the upper wall 13 of the cap 1, and the tilted open position, shown in Figures 4, 9 and 11, in which the outer peripheral skirt 14 extends upward from the upper wall 13 of the cap 1. In In the embodiment shown, the articulation device 10 includes two blades 11, 12, in particular visible in Figure 4, which join the cap 1 and, more particularly, the outer peripheral skirt 14 of the cap 1 with the lower ring 9, and more particularly, with the second sector 17 of the lower ring 9. The two blades 11, 12 are symmetrical with respect to the bisector plane Pb.
    [0128] The locking device includes a bead 22, in particular, visible in figure 1, which is formed in the outer peripheral skirt 14 of the cap 1. The bead 22 is arranged between the two blades 11, 12. The lower end of the bead 22 it is advantageously located at the same height as the lower end of the outer peripheral skirt 14. The bead 22 includes a stop 23 which extends circumferentially about the X-axis and projects radially outward from the bead 22.
    [0130] During the movement of the cap 1 from the released position towards the tilted open position, the stop 23 abuts against the upper end of the second sector 17 of the lower ring 9 which tends to return said second sector 17 towards the lowered position.
    [0132] On the other hand, during the movement of the cap 1 from the tilted open position towards the released position, at first, the stop 23 rests against the hooking collar 5, as shown in figure 10, to exert on the second sector 17 of the lower ring 9 a tensile force having a radially outwardly directed component and an upwardly axially directed component. This allows the lower ring 9 to be moved from front to back to press the front zone 19 of the first sector 16 of the lower ring 9 against the neck 2 of the container in order to facilitate the movement of the second sector 17 towards the raised position. This also allows to aid the movement of the second sector 17 between the lowered position and the raised position.
    [0134] Then, as shown in figure 10, during the movement of the cap 1 from the tilted open position towards the released position, the outer surface of the bead 22 comes in a second moment, resting against the upper surface of a helical rib of the thread. helical 6 formed in the neck 2 of the container, which also allows a pulling force to be exerted on the second sector 17 having a component directed radially outward and a component directed upward to move the second sector 17 towards the raised position.
    [0135] On the other hand, as shown in Figure 11, the lower end 24 of the helical thread 7 formed on the inner face of the outer peripheral skirt 14, that is, the beginning of the helical thread 7, is arranged in an angular interval S2 which is defined between the bisector plane Pb and a radial plane Pr located at 160 ° from the bisector plane Pb according to a second direction opposite to the first direction of rotation, that is, in the direction of rotation of the helical thread 7 about the axis X. Thus, a lower front portion 25 of the outer peripheral skirt 14 lacks a helical thread 7, which makes it easier to fit the cap 1 on the neck 2 of the container. This arrangement is particularly advantageous when the cap 1 is capable of being presented in a slightly rearwardly displaced position when it comes into contact with the neck 2 of the container. This is particularly the case, when the hooking elements 18 are absent from the front zone 19 of the first sector 16 and that, consequently, the lower ring 9 can move radially from the front to the rear with respect to the neck 2 of the container.
    [0137] Advantageously, the lower end of the helical thread 7 is arranged in an angular interval defined between two radial planes respectively positioned at 90 ° and 160 ° from the bisector plane Pb according to a second direction of rotation opposite to the direction of the thread. helical 7 of plug 1.
    [0139] On the other hand, as schematically represented in Figures 8, 9 and 10, at least one of the ribs of the series of ribs of the helical thread 7 is formed on the inner face of the bead 22. In other words, at least one of the ribs of the helical thread 7 is formed between the two blades 11, 12 of the articulation device 10. The presence of said rib formed in the heel 22 makes it possible to increase the resistance to pressure of the helical thread 7 and therefore therefore, it prevents the cap 1 from opening unintentionally due to excessive pressure in the container, in particular when it is intended to receive carbonated beverages.
    [0141] The kinematics of plug 1 is as follows. During the first unscrewing, the cap 1 leaves the closed position and moves away from the lower ring 9 to the released position, illustrated in figure 3. The frangible bridges break during this movement. Furthermore, during this unscrewing movement of the cap 1, the lower ring 9 is driven in rotation around the X axis and the second sector 17 of the lower ring 9 rotates towards the raised position as the cap 1 moves away from the hooking collar 5 .
    [0142] The cap 1 can then then be rotated rearwardly in the direction of the open tilted position in which the outer peripheral skirt 14 extends upward from the upper wall 13. During movement of the cap 1 backward in the direction of its position tilted open, the stop 23 abuts against the upper end of the second sector 17 of the lower ring 9, so that the second sector 17 of the lower ring 9 rotates from the raised position to the lowered position.
    [0144] As shown in figure 9, when the second sector 17 of the lower ring 9 is in the lowered position and the cap 1 is in its tilted open position, the stop 23 is supported against the hooking collar 5. Thus, the cap 1 remains in its tilted open position since, due to this abutment of the stop 23 against the hooking collar 5, the cap 1 cannot rotate towards the released position in which the cap 1 faces the dispensing orifice 3 while the second sector 17 of the lower ring 9 remains in the lowered position. This makes it possible to increase the minimum opening angle of the cap 1. Thus, advantageously, when the cap 1 is in its tilted open position and the second sector 17 of the lower ring 9 is in the lowered position, the opening angle of the plug 1 is greater than 120 ° and, advantageously, greater than or equal to 145 ° and, for example, of the order of 180 °. The opening angle corresponds to the projecting angular sector that is formed at the intersection between a plane parallel to the upper wall 13 of the cap 1 and a horizontal plane.
    [0146] To reclose the cap 1, the user swings the cap 1 forward to the released position. During this tilting, the stop 23 bears against the hooking collar 5 to exert on the second sector 17 of the lower ring 9 a traction force having a radially outwardly directed component that makes it possible to move the lower ring 9 from the front towards rearward and a component directed axially upwards that allows to aid the movement of the second sector 17 of the lower ring 9 towards the raised position. The outer surface of the heel 22 also abuts against a helical rib of the helical thread 6 which also facilitates movement of the second sector 17 of the lower ring 9 towards the raised position.
    [0148] When the second sector 17 is in the raised position and the cap 1 is in the released position, said cap 1 can then be screwed back into the neck 2 of the container. During screwing, the lower ring 9 is driven in rotation around the X axis and the second sector 17 of the lower ring 9 rotates towards the lowered position as the plug 1 is close to the hooking collar 5.
    [0149] Advantageously, the assembly of the capping device is molded in a single piece of synthetic material, such as polyethylene and advantageously high-density polyethylene. Advantageously, the capping device is molded in the configuration of figure 1, that is, in a closed position, a position in which it can be mounted directly on the neck 2 of the container.
    [0151] Although the invention has been described in relation to several particular embodiments, it is more than evident that it is not limited in any way by them and that it comprises all the technical equivalents of the means described, as well as their combinations if they enter into the framework of the invention as defined by the claims.
