Abstract
Description
- The invention refers to an assembly comprising a container and a capping device which is equipped with a stopper and enables the stopper to be kept fixed to the neck of a container, thus preventing the stopper from being lost altogether.
- Document
ES1232089U - This capping device is not completely satisfactory. In particular, this capping device is capable of exhibiting insufficient resistance to pressure, so that the cap is liable to open inadvertently due to too great a pressure in the container, particularly when it is intended to store carbonated drinks.
- Furthermore, despite the absence of means of attachment to the section of the lower ring that is connected to the cap by the joint, manipulations of the cap to allow the section of the lower ring that is connected to the cap to rotate into a raised position when the cap must be moved from the open tilted position to the closed position are not easy.
- An underlying idea of the invention is to propose a capping device which will enable a cap to be kept attached to the neck of the container which is reliable, easy to make and use.
- According to one embodiment, the invention provides a capping device intended to be fixed on the neck of a container including an orifice, including the capping device:
- a cap that includes a top wall and an external peripheral skirt, with the external peripheral skirt having a helical thread formed by a series of ribs and intended to cooperate with a helical thread formed in the neck to allow:
- a unscrewing of the neck cap around an X-axis to move the cap from a closing position where the top wall closes the neck hole and the outer peripheral skirt surrounds the neck to a released position where the cap is no longer attached to the neck; and
- a screwing of the cap on the neck to move the cap from the released position to the closing position;
- a lower ring fixed axially to the neck and moving in rotation about the neck along the X axis; and
- a hinge device that joins the cap to the lower ring, including the hinge device two plates that connect the outer peripheral skirt and the lower ring and are arranged to allow the cap to rotate between the released position and an open tilted position where the cap disengages from the neck hole,
- This allows the pressure resistance of the capping device to be improved.
- Depending on other advantageous embodiments, a capping device of this type may have one or more of the following characteristics.
- According to one embodiment, the lower ring includes a first sector comprising coupling elements which project radially into the lower ring and are intended to be arranged under the coupling collar to retain the lower ring axially in the container neck and a second sector, the first sector and the second sector of the lower ring are hinged together in such a way that the second sector rotates with respect to the first sector between a lowered position where the second sector is intended to be arranged under the locking collar and a raised position where the second sector is intended to be arranged at least partially above the locking collar.
- According to one embodiment, the first sector of the lower ring, a front zone which is diametrically opposed to the second sector and two coupling zones which are each arranged between the front zone of the first sector and the second sector, the coupling elements are arranged only in the two coupling zones to allow a radial movement of the lower ring capable of facilitating the passage of a part of the second sector to each side of the coupling collar during the movement of the second sector between the lowered and the released position. In this way, the tensile forces that will be exerted on the lower ring to allow the second sector to move between the lowered and the raised position are lower, making the use of the capping device easier.
- According to one embodiment, the coupling elements are protrusions that project radially inwards.
- Depending on the embodiment, the second sector extends over an angular range of 90° to 150°.
- Depending on the embodiment, the front of the second sector extends over an angular range of 90° to 150°.
- Depending on the embodiment, each of the two attachment areas extends over an angular range of between 30° and 90°.
- According to one embodiment, the hinge device is extended over a first angular interval that is cut in two equal parts by a Pb bisector plane, the two hinge areas are extended over angular sectors that are symmetrical with respect to the Pb bisector plane.
- According to one embodiment, the hinge device extends over a first angular interval which is cut in two equal parts by a Pb bisector plane and in which the helical thread formed on the outer peripheral skirt of the cap develops around the X axis according to a first direction and has a lower and an upper end, the lower end of the helical thread is arranged in a second angular interval which is defined between the Pb bisector plane and a radial plane positioned at 160° from the Pb bisector plane according to a second direction opposite to the first direction. This facilitates the coupling of the cap in the neck when moving the cap from the open tilted position to the closed position.
- According to one embodiment, the invention also refers to an assembly comprising a container equipped with a neck including a distribution hole, a coupling collar and a helical thread and a capping device mentioned above, the lower ring being fixed axially to the neck and being mobile in rotation on the neck around said X-axis.
- Depending on the embodiment, the capping device also includes a locking device configured to lock the cap in the open tilted position, including a stop that projects radially outwards from the cap and is configured to rest against the neck attachment collar during movement of the cap from the open tilted position to the position released for use in the second sector, a tensile force that has a component directed radially outwards and a component directed axially upwards to assist the movement of the second sector between the lowered position and the raised position. This makes it even easier to use the capping device, particularly when the cap has to be moved from the open tilted position to the closed position.
- According to one embodiment, the stop is configured so that, during movement of the cap from the released position to the open tilted position, the stop rests against an upper end of the second sector of the lower ring to move it from the raised position to the lowered position. This also makes it easier to use the capping device.
- Depending on the embodiment, the locking device also includes a bead that is formed on the outer peripheral skirt of the cap and is extended axially, with the heel configured to rest against a helical rib of the helical thread formed in the neck of the container during movement of the cap from the open tilted position to the released position to exert a tensile force on the second sector which has a component directed radially outwards and a component directed axially upwards to assist movement of the second sector from the lowered position to the raised position. This also makes it easier to use the capping device.
- Depending on the embodiment, the hinge device includes two blades and the heel is formed between the two blades.
- Depending on the embodiment, the stop protrudes radially outwards from the heel.
- The invention will be better understood and other purposes, details, features and advantages thereof will become more apparent in the following description of several particular embodiments of the invention, provided solely by way of illustration and not limitation, with reference to the attached drawings.

Figure 11 is a perspective view of the capping device mounted on the neck of the container and showing the cap of the capping device in the tilted open position. - 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 theneck 2 of the container. By convention, the "radial" orientation is directed orthogonal to the axis X and the axial orientation is directed parallel to the axis X. The terms "external" and "internal" are used to define the relative position of one element with respect to another, by reference to the X axis, an element close to the axis X is thus classified as internal as opposed to an external element located radially on the periphery. - 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
orifice 3 of theneck 2 is oriented upwards and thecap 1 is in the closed position on theneck 2 of the container, an element intended to be placed lower being named lower and an element intended to be placed higher being named, upper. The terms "front" and "back" are used to define the relative position of one element with respect to another along a diameter perpendicular to the axis X. - With reference to
Figures 1 to 10 , an assembly comprising a capping device, represented, in particular, inFigure 1 , and a container equipped with aneck 2, represented, in particular, inFigure 2 , are described below. - As shown in
figure 2 , theneck 2 of the container has an upper end on which anorifice 3 is formed that allows the contents of the container to be poured. Theneck 2 of the container includes asupport collar 4 projecting radially outward and anengaging collar 5 that also projects radially outward and is arranged axially between thesupport collar 4 and theorifice 3. A cylindrical portion is axially formed between thesupport collar 4 and theorifice 3. On the other hand, theneck 2 includes, axially positioned between theengaging collar 5 and theorifice 3, ahelical thread 6 formed by a series of helical ribs, projecting radially towards the exterior from an external surface of theneck 2. Thehelical thread 6 is intended to cooperate with a complementaryhelical thread 7 formed from a series of helical ribs that are formed on thecap 1 of the capping device. - According to one embodiment, the
helical thread 6 formed on theneck 2, as well as thehelical thread 7 formed on thecap 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 thecap 1 is still attached to theneck 2. - The capping device includes a
lower ring 9 that is retained in theneck 2 of the container, acap 1 that is intended to cover theorifice 3 of the container in order to seal it, ahinge device 10 that joins thecap 1 with thelower ring 9 and a locking device positioned to lock thecap 1 in an tilted open position, shown inFigures 4 ,9 and11 . - In the tilted open position,
cap 1 is disengaged from theorifice 3 of the container and does not hinder the pouring of the contents of the container. - As illustrated in
Figures 7 and 8 , thehinge device 10 extends over an angular range S1 which is intersected in two equal parts by a vertical bisection plane Pb. - Returning to
Figure 1 , it is observed that thecap 1 includes anupper wall 13 intended to be arranged substantially and orthogonally to the axis X, opposite theorifice 3 of theneck 2 when saidcap 1 is in the closed position. Thecap 1 further includes an outerperipheral skirt 14 intended to surround theneck 2 of the container when thecap 1 is in the closed position. The outerperipheral skirt 14 extends, downward, perpendicular to theupper wall 13, from the outer periphery of saidupper wall 13. - The outer
peripheral skirt 14 has, on its inner face, ahelical thread 7, visible inFigures 2 and5 to 7 , formed by a series of helical ribs that extend around the axis X in a first direction of rotation. Thehelical thread 7 is intended to cooperate with thehelical thread 6 formed on the external surface of theneck 2. In this way, thecap 1 is able to screw into theneck 2 in order to close the container and to unscrew from theneck 2 in order to open the container. Thecap 1 can thus be moved between a closed position and a released position, shown infigure 3 . In said released position, thecap 1 is no longer engaged with theneck 2. Therefore, it is capable of tilting towards the tilted open position, represented infigures 4 ,9 and11 , wherein thecap 1 is disengaged from theorifice 3 of theneck 2 so as not to hinder the pouring of the contents of the container. - As shown in particular in
Figure 9 , thecap 1 also includes aninternal skirt 8, which extends perpendicularly downward from theupper wall 13 of thecap 1 and is dimensioned to insert into theorifice 3 of theneck 2. Thecap 1 also includes anannular lip 15 extending, from theupper wall 13, radially between theinner skirt 8 and the outerperipheral skirt 14. Theinner skirt 8 and theannular lip 15 are dimensioned so that, when thecap 1 is in the closed position, in theneck 2 of the container, theinner skirt 8 is in contact against the inner face of theneck 2 while theannular lip 15 is in contact against the outer face of theneck 2. In this way, theinternal skirt 8 and theannular lip 15 make it possible to guarantee the sealing of the closure. - Advantageously, the
lower ring 9 is, before the first opening of the container, connected to thecap 1 by some frangible bridges, not visible in the figures, intended to be broken during the opening of thecap 1. These frangible bridges thus constitute tamperproof seals. - The
lower ring 9 is held axially on theneck 2 of the container while it can rotate with respect to it about the axis X. As shown infigure 3 , thelower ring 9 includes two parts that are articulated to each other, that is, afirst section 16 and asecond section 17 whereby thelower ring 9 is connected to cap 1 by means of thehinge device 10. - 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 thelower ring 9 outside of said narrowed areas. The two narrowed areas delimit thefirst section 16 and thesecond section 17. The narrowed areas thus form pivots that allow thesecond section 17 to articulate with respect to thefirst section 16. - According to another embodiment, the
lower ring 9 does not have narrowed areas that delimit the first andsecond sections - The
second section 17 is able to rotate upwards with respect to thefirst section 16, between a lowered position in which thesecond section 17 is intended to be arranged under the engagingcollar 5 and a raised position, wherein thesecond section 17 is arranged at least in part above the engagingcollar 5. This allows thecap 1 to move upward relative to theneck 2 of the container, untilhelical thread 7 ofcap 1 disengages from thehelical thread 6 formed on theneck 2 of the container. In other words, whencap 1 is unscrewed, thelower ring 9 is rotatably driven around the axis X while thesecond section 17 of thelower ring 9 rotates with respect tofirst section 16 to the raised position to allow axial movement, up thecap 1, from the closed position, to the released position, represented infigure 3 . When thecap 1 rotates from the released position to the tilted open position, thesecond section 17 of thelower ring 9 rotates in the opposite direction with respect to thefirst section 16 and then returns to the lowered position. On the other hand, as described in more detail below, thesecond section 17 also rotates relative to thefirst section 16 from the lowered position to the raised position when thecap 1 rotates from the tilted open position to the released position. - The
lower ring 9 is held axially on theneck 2 of the container by means of theengaging collar 5, in particular, visible inFigures 5 to 7 . Theengaging collar 5 presents a frusto-conical external surface that tapers upwards, that is, in direction to theorifice 3 of the container. Theengaging collar 5 delimits, downwards, that is, in a direction opposite to theorifice 3, a projection. Thefirst section 16 of thelower ring 9 includesengaging elements 18 that cooperate with theengaging collar 5 formed on the container in order to axially retain thelower ring 9 to theneck 2 of the container. Theengaging elements 18 are protrusions, represented in detail in particular inFigures 5 and 6 , which protrude radially inward from thefirst section 16 of thelower ring 9. The retainingelements 18 have a radial dimension that increases, from bottom to top, that is to say, in the direction of the upper edge of thelower ring 9. During the assembly of the capping device on theneck 2 of the container, theengaging elements 18 slide against the frusto-conical surface of theengaging collar 5 and then are locked by an elastic return behind the engagingcollar 5. - As shown in
Figures 5 and 6 , thefirst section 16 of thelower ring 9 includes afront area 19 that is diametrically opposite to thesecond section 17 of thelower ring 9 and twoengagement areas front area 19 and are each arranged between thefront area 19 and thesecond section 17 of thelower ring 9. Theengaging elements 18 are only arranged in the twoengagement areas elements 18 in the front area of thefirst section 16, there is a radial space between thelower ring 9 and theneck 2 that allows thelower ring 9 to move from front to back and vice versa. The radial clearance between thelower ring 9 and theneck 2 in the front / rear direction is, for example, between 0.5 and 1 mm. This facilitates the passage of a part of thesecond section 17 on either side of theengaging collar 5 during the movement of thesecond section 17 between the lowered position and the raised position. In other words, the tensile forces that shall be exerted on thelower ring 9 to allow thesecond section 17 to pass to each side of theengaging collar 5 are less. - Advantageously, the
second section 17 extends over an angular range between 90 and 150°, and for example, in the order of 120°, the front area of thesecond section 16 extends over an angular range between 90 and 150°, for example, in the order of 120°, while each of the twoengagement areas - On the other hand, the bisection plane Pb cuts the
second section 17 into two equal parts, as well as the front part of thesecond section 17. The angular ranges corresponding to the twoengagement areas - The
hinge device 10 is configured to allow thecap 1 to rotate between the released position, shown inFigure 3 , wherein the outerperipheral skirt 14 extends downward from theupper wall 13 of thecap 1, and the tilted open position, represented inFigures 4 ,9 and11 , wherein the outerperipheral skirt 14 extends upwards from theupper wall 13 of thecap 1. In the embodiment shown, thehinge device 10 includes twofoils figure 4 , which join thecap 1 and, more particularly, the outerperipheral skirt 14 of thecap 1 with thelower ring 9, and more particularly, with thesecond section 17 of thelower ring 9. The two foils 11, 12 are symmetric with respect to the bisection plane Pb. - The locking device includes a
heel 22, in particular, visible infigure 1 , which is formed on the outerperipheral skirt 14 of thecap 1. Theheel 22 is arranged between the two foils 11, 12. The lower end of theheel 22 it is advantageously located at the same height as the lower end of the outerperipheral skirt 14. Theheel 22 includes astop 23 which extends circumferentially about the axis X and projects radially outward from theheel 22. - During the movement of the
cap 1 from the released position towards the tilted open position, thestop 23 abuts against the upper end of thesecond section 17 of thelower ring 9 which tends to return saidsecond section 17 towards the lowered position. - On the other hand, during the movement of the
cap 1 from the tilted open position towards the released position, at first, thestop 23 rests against the engagingcollar 5, as shown infigure 10 , to exert on thesecond section 17 of the lower ring 9 a tensile force having a component directed radially outward and a component directed axially upward. This allows thelower ring 9 to be moved from the front to the rear to press thefront area 19 of thefirst section 16 of thelower ring 9 against theneck 2 of the container in order to facilitate the movement of thesecond section 17 towards the raised position. This also allows aiding the movement of thesecond section 17 between the lowered position and the raised position. - Then, as shown in
figure 10 , during the movement of thecap 1 from the tilted open position to the released position, the outer surface of theheel 22, comes in a second moment, rests against the upper surface of a helical rib of thehelical thread 6 formed in theneck 2 of the container, which also allows to exert on the second section 17 a tensile force having a component directed radially outward and a component directed upward to move thesecond section 17 towards the raised position. - On the other hand, as shown in
Figure 11 , thelower end 24 of thehelical thread 7 formed on the inner face of the outerperipheral skirt 14, that is, the beginning of thehelical thread 7, is arranged in an angular range S2 which is defined between the bisection plane Pb and a radial plane Pr located at 160° from the bisection plane Pb according to a second direction opposite to the first direction of rotation, that is, in the direction of rotation of thehelical thread 7 about the axis X. Thus, alower front portion 25 of the outerperipheral skirt 14 lacks ahelical thread 7, which makes it easier to fit thecap 1 on theneck 2 of the container. This arrangement is particularly advantageous when thecap 1 is capable of being presented in a slightly rearward position when it comes into contact with theneck 2 of the container. This is particularly the case, when theengaging elements 18 are absent from thefront area 19 of thefirst section 16 and that, consequently, thelower ring 9 can move radially from front to back with respect to theneck 2 of the container. - Advantageously, the lower end of the
helical thread 7 is arranged in an angular range defined between two radial planes respectively positioned at 90 ° and 160 ° from the bisection plane Pb according to a second direction of rotation opposite the direction of thehelical thread 7 of thecap 1. - 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 thehelical thread 7 is formed on the inner face of theheel 22. In other words, at least one of the ribs of thehelical thread 7 is formed between the two foils 11, 12 of thehinge device 10. The presence of said rib formed on theheel 22 makes it possible to increase the resistance to pressure of thehelical thread 7 and, therefore, preventscap 1 from opening unintentionally due to excessive pressure on the container, in particular when it is intended to receive carbonated beverages. - The kinematics of the
cap 1 is as follows. During the first unscrewing, thecap 1 leaves the closed position and moves away from thelower ring 9 to the released position, illustrated infigure 3 . The frangible bridges break in the course of this movement. Furthermore, during this unscrewing movement of thecap 1, thelower ring 9 is rotatably driven around the axis X and thesecond section 17 of thelower ring 9 rotates towards the raised position as thecap 1 moves away from the engagingcollar 5. Thecap 1 can then be rotated backwards in the direction of the open tilted position in which the outerperipheral skirt 14 extends upward from thetop wall 13. During the movement of thecap 1 back in the direction of its open tilted position, thestop 23 abuts against the upper end of thesecond section 17 of thelower ring 9, so that thesecond section 17 of thelower ring 9 rotates from the raised position to the lowered position. - As shown in
figure 9 , when thesecond section 17 of thelower ring 9 is in the lowered position and thecap 1 is in its tilted open position, thestop 23 is supported against the engagingcollar 5. In this way, thecap 1 remains in its tilted open position since, due to this abutment of thestop 23 against the engagingcollar 5, thecap 1 cannot rotate towards the released position in which thecap 1 faces the dispensingorifice 3 while thesecond section 17 oflower ring 9 remains in the lowered position. This makes it possible to increase the minimum opening angle of thecap 1. Thus, advantageously, when thecap 1 is in its tilted open position and thesecond section 17 of thelower ring 9 is in the lowered position, the opening angle of thecap 1 is greater than 120° and, advantageously, greater than or equal to 145° and, for example, in the order of 180°. The opening angle corresponds to the projecting angular section that is formed at the intersection between a plane parallel to theupper wall 13 of thecap 1 and a horizontal plane. - To close the
cap 1 again, the user tilts thecap 1 forward to the released position. During this tilting, thestop 23 rests against the engagingcollar 5 to exert on thesecond section 17 of the lower ring 9 a tensile force that has a component directed radially outward that makes it possible to move thelower ring 9 from front to back and a component directed axially upwards that allows to aid the movement of thesecond section 17 of thelower ring 9 towards the raised position. The outer surface of theheel 22 also abuts against a helical rib of thehelical thread 6 which also facilitates the movement of thesecond section 17 of thelower ring 9 towards the raised position. - When the
second section 17 is in the raised position and thecap 1 is in the released position, thecap 1 can then be screwed back into theneck 2 of the container. During screwing, thelower ring 9 is rotatably driven around the axis X and thesecond section 17 of thelower ring 9 rotates towards the lowered position as thecap 1 is close to theengaging collar 5. - Advantageously, the entire 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 theneck 2 of the container. - Although the invention has been described in relation to various 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 fall within the framework of the invention as defined by the claims.
- The use of the verb "consist of", "comprise" or "include" and its conjugated forms do not exclude the presence of other elements or stages other than those established in a claim.
- In the claims, any reference signs in parentheses are not to be construed as limiting the claim.
