The present invention relates to an assembly comprising a container and a capping device comprising a closure and making it possible to keep the closure fixed to the neck of the container, thereby preventing its complete loss.

Patent document ES1232089U describes a lower ring intended to be axially fixed to the neck of the container and a thread and cap intended to be attached to an additional thread formed in the gland of the container. A capping device is disclosed that includes a cap that includes a joint that interfaces with a ring. The lower ring includes attachment means intended to hold the lower ring to the gland of the container. The portion where the attachment means are present ranges from 25-75% of the diameter of the lower ring. The part of the lower ring connected to the stopper by a hinge arrangement is free of attachment means so that it can be rotated between its lowered and raised positions, in particular to unscrew the stopper. It is possible. The cap also includes ratchet means intended to cooperate with complementary ratchet means formed on the lower ring by which the cap can be retained in the tilted open position.

This capping device is not good enough. In particular, the capping device may exhibit insufficient resistance to pressure, and excessive pressure within the container is likely to cause the cap to open inadvertently, especially if carbonated beverages are intended to be stored.

Also, when the cap has to be moved from the tilted open position to the closed position, although there is no means of attachment to the portion of the lower ring connected to the cap by the joint, the portion of the lower ring connected to the cap is It is not easy to handle the cap for rotating the to the raised position.

The basic idea of the invention is to propose a capping device that is reliable, easy to manufacture and to use, which makes it possible to hold the cap on the neck of the container.

According to one embodiment, the first sector of the lower ring has a front region diametrically opposed to the second sector and between the front region of the first sector and the second sector each and the coupling elements are arranged only in the two coupling areas to allow radial movement of the lower ring and the second sector to move between the lowered and raised positions. In some cases it is possible to facilitate passage of a portion of the second sector on both sides of the coupling collar. In this way, less pulling force is applied to the lower ring to move the second sector between the lowered and raised positions, facilitating the use of the capping device.

According to one embodiment, the coupling element is a radially inwardly projecting protrusion.

A stop configured to apply a tensile force having a component and an axially upwardly directed component. This makes the capping device easier to use, especially when the cap needs to be moved from the tilted open position to the closed position.

According to one embodiment, the stop abuts the upper end of the second sector of the lower ring and moves the second sector from the raised position to the lowered position when the cap moves from the released position to the tilted open position. configured to move. This also facilitates the use of capping devices.

According to an embodiment, the locking device also includes an axially extending bead formed on the outer peripheral skirt of the cap, the heel engaging a helical thread formed on the neck of the container as the cap moves from the tilted open position to the released position. A radially outwardly directed component and an axially upwardly directed component are provided in the second sector to abut the helical ribs of the section and assist in movement of the second sector from the lowered position to the raised position. configured to apply a tensile force having a component. This also facilitates the use of capping devices.

In the description and drawings, the axis X corresponds to the axis of rotation when the cap 1 of the capping device is screwed onto the neck 2 of the container. By convention, the "radial" orientation is oriented perpendicular to the X axis and the axial orientation is oriented parallel to the X axis. The terms "external" and "internal" are used to define the relative position of one element with respect to another with respect to the X-axis, the element closer to the X-axis being the outer element located radially on the periphery. classified as internal to

The terms "upper" and "lower" define the relative position of one element to another relative to the position in which the orifice 3 of the neck 2 is directed upwards and the cap 1 is in the closed position on the neck 2 of the container. Elements intended to be placed lower are referred to as lower and elements intended to be placed higher are referred to as upper. The terms "front" and "back" are used to define the relative position of one element to another along a radius that is perpendicular to the X axis.

1 to 10, an assembly comprising a capping device, represented in particular in FIG. 1, and a container with a neck 2, represented in particular in FIG. 2, will be described below.

As shown in Figure 2, the neck 2 of the container has an upper end formed with an orifice 3 that allows the contents of the container to be poured out. The container neck 2 includes a radially outwardly projecting support collar 4 and a radially outwardly projecting engagement collar 5 axially disposed between the support collar 4 and the orifice 3 . A cylinder is formed axially between the support collar 4 and the orifice 3 . The neck 2, on the other hand, is axially disposed between the engagement collar 5 and the orifice 3 and is formed by a series of spiral ribs projecting radially outwardly from the outer surface of the neck 2. Includes threaded portion 6 . The helical thread 6 is intended to cooperate with a complementary helical thread 7 formed by a series of helical ribs formed on the cap 1 of the capping device.

According to one embodiment, the helical thread 6 formed in the neck 2 and the helical thread 7 formed in the cap 1 are intermittent. In other words, adjacent helical ribs are separated by spaces forming vents and, in particular, allowing gas present in the container to escape while the cap 1 is attached to the neck 2. . The capping device comprises a lower ring 9 held in the neck 2 of the container, a cap 1 intended to cover to seal the orifice 3 of the container, a hinge device 10 joining the cap 1 with the lower ring 9, and a locking device arranged to lock the cap 1 in the tilted open position shown in FIGS. In the tilted open position the cap 1 is removed from the orifice 3 of the container and the pouring of the contents of the container is unimpeded.

As shown in FIGS. 7 and 8, the hinge device 10 extends over an angular range S1 bisected by a perpendicular bisector Pb.

Referring again to Figure 1, the cap 1 has a top wall 13 intended to be arranged substantially perpendicular to the axis X opposite the orifice 3 of the neck 2 when said cap 1 is in the closed position. including. The cap 1 further comprises a peripheral skirt 14 intended to surround the neck 2 of the container when the cap 1 is in the closed position. A peripheral skirt 14 extends downward from the outer periphery of the top wall 13 perpendicularly to the top wall 13 .

Peripheral skirt 14 has on its inner surface a helical thread 7 formed by a series of helical ribs extending in a first rotational direction about axis X, shown in FIGS. 2 and 5-7. The helical thread 7 is intended to cooperate with the helical thread 6 formed on the outer surface of the neck 2 . In this way the cap 1 can be screwed onto the neck 2 to close the container and unscrewed from the neck 2 to open the container. The cap 1 can thus be moved between the open and closed positions shown in FIG. In the released position, cap 1 is not engaged with neck 2 . It is therefore possible to tilt towards the tilted open position represented in Figures 4, 9 and 11, in which the cap 1 is opened at the neck such that the pouring of the contents of the container is not impeded. 2 from the orifice 3.

As shown particularly in FIG. 9, the cap 1 also includes an inner skirt 8 extending vertically downward from the top wall 13 of the cap 1 and dimensioned to be inserted into the orifice 3 of the neck 2 . Cap 1 also includes an annular lip 15 extending radially from top wall 13 between inner skirt 8 and outer skirt 14 . The inner skirt 8 and the annular lip 15 are dimensioned such that the inner skirt 8 abuts the inner surface of the neck 2 and the annular lip 15 abuts the outer surface of the neck 2 in the neck 2 of the container when the cap 1 is in the closed position. be. In this way, the inner skirt 8 and the annular lip 15 make it possible to ensure the tightness of the closure.

Advantageously, before the container is first opened, the lower ring 9 is connected to the cap 1 by several frangible bridges, not visible in the figure, intended to break when opening the cap 1. . These weakened bridges therefore constitute tamper evident seals.

The lower ring 9 is axially retained on the container neck 2 while being rotatable about the axis X relative to the container neck 2 . As shown in FIG. 3, the lower ring 9 comprises two parts joined together, a first part 16 and a second part 17 connected to the cap 1 by a hinge device 10 .

According to one embodiment, the lower ring 9 comprises two constricted regions, ie its radial thickness is smaller than the radial thickness of the lower ring 9 outside said constricted regions. The two constricted regions define first portion 16 and second portion 17 . The constricted region thus forms a pivot that allows the second portion 17 to be coupled to the first portion 16 .

According to another embodiment, the lower ring 9 does not have a constricted area defining the first and second portions 16,17.

The second part 17 has a lowered position in which the second part 17 is intended to be arranged below the engagement collar 5 and a position in which the second part 17 is arranged at least partially above the engagement collar 5 . It is possible to rotate upward relative to the first part 16 between the raised position where it is pushed. This allows the cap 1 to move upwards relative to the container neck 2 until the helical thread 7 of the cap 1 disengages from the helical thread 6 formed in the container neck 2 . In other words, when the cap 1 is unscrewed, the second portion 17 of the lower ring 9 rotates to the raised position relative to the first portion 16 while the lower ring 9 is rotationally driven about the axis X, It allows an axial movement to lift the cap 1 from the closed position to the open position represented in FIG. As the cap 1 rotates from the released position to the tilted open position, the second portion 17 of the lower ring 9 rotates in the opposite direction relative to the first portion 16 and then returns to the lowered position. On the other hand, the second portion 17 also rotates from the lowered position to the raised position relative to the first portion 16 when the cap 1 rotates from the tilted open position to the released position, as will be described in detail below.

The lower ring 9 is axially retained on the neck 2 of the container by means of an engaging collar 5, shown in particular in Figures 5-7. The engagement collar 5 presents a frusto-conical outer surface that tapers upwards, i.e. in the direction of the orifice 3 of the container. The engagement collar 5 defines a projection downwards, i.e. in the direction opposite the orifice 3 . A first portion 16 of the lower ring 9 comprises engagement elements 18 cooperating with an engagement collar 5 formed on the container to axially retain the lower ring 9 on the neck 2 of the container. The engagement elements 18 are projections projecting radially inwardly from the first portion 16 of the lower ring 9, which are shown in particular in FIGS. 5 and 6 in detail. The retaining elements 18 have a radial dimension that increases from bottom to top, ie in the direction of the upper edge of the lower ring 9 . During assembly of the capping device on the neck 2 of the container, the engagement element 18 slides on the frusto-conical surface of the engagement collar 5 and is then locked behind the engagement collar 5 by elastic return.

As shown in FIGS. 5 and 6, the first portion 16 of the lower ring 9 is arranged on both sides of the front region 19 diametrically opposite the second portion 17 of the lower ring 9 . , each comprising two engagement regions 20 , 21 arranged between the front region 19 and the second portion 17 of the lower ring 9 . Engagement elements 18 are arranged only in two engagement areas 20 , 21 . Therefore, the absence of engagement elements 18 in the front region of the first portion 16 prevents the movement of the lower ring 9 from front to back and vice versa between the lower ring 9 and the neck 2 . There is radial space to allow. The radial gap between the lower ring 9 and the neck 2 in the front/rear direction is for example 0.5-1 mm. This facilitates passage of a portion of the second portion 17 on either side of the engagement collar 5 as the second portion 17 moves between the lowered and raised positions. In other words, there is less pulling force on the lower ring 9 to pass the second portion 17 on either side of the engagement collar 5 .

Advantageously, the second portion 17 extends over an angular range of approximately 90-150°, for example approximately 120°, and the front region of the second portion 16 extends over an angular range of 90-150°, such as approximately 120°. each of the two engagement areas 20, 21 extends over an angular range comprised between 30 and 90°, for example about 60°.

On the other hand, the bisecting plane Pb bisects the second portion 17 and separates the front portion of the second portion 17 . Accordingly, the angular ranges corresponding to the two engagement regions 20, 21 are symmetrical to each other with respect to the bisecting plane Pb.

Hinge device 10 can be positioned in a released position, shown in FIG. It is arranged to allow the cap 1 to rotate between an inclined open position extending upwardly from the wall 13 . In the illustrated embodiment, the hinge device 10 comprises two foils 11, 12, shown in particular in FIG. is joined with the second portion 17 of the lower ring 9 . The two foils 11, 12 are symmetrical about the bisecting plane Pb.

The locking device comprises a heel 22 formed on the peripheral skirt 14 of the cap 1, shown in particular in FIG. A heel 22 is arranged between the two foils 11,12. The lower edge of the heel 22 is advantageously level with the lower edge of the peripheral skirt 14 . Heel 22 extends circumferentially about axis X and includes a stop 23 projecting radially outwardly from heel 22 .

When the cap 1 moves from the released position towards the tilted open position, the stop 23 abuts the upper end of the second part 17 of the lower ring 9, which returns said second part 17 towards the lowered position. Helpful.

On the other hand, when the cap 1 moves from the tilted open position towards the released position, the stop 23 initially abuts the engagement collar 5 as shown in FIG. A tensile force is applied that has an outwardly directed component and an axially upwardly directed component. This causes the lower ring 9 to move from front to rear, pressing the front region 19 of the first portion 16 of the lower ring 9 against the neck 2 of the container, in order to facilitate the movement of the second portion 17 towards the raised position. Is possible. This also makes it possible to assist the movement of the second part 17 between the lowered and raised positions.

Thereafter, as shown in FIG. 10, when the cap 1 moves from the tilted open position to the released position, the outer surface of the heel 22 enters a second stage, causing the helical thread 6 formed in the neck 2 of the container to spiral out. upper surface of the rib, thereby exerting a tensile force having a radially outwardly directed component and an upwardly directed component on the second portion 17 to urge the second portion 17 toward the raised position. It is also possible to move

On the other hand, as shown in FIG. 11, the lower end 24 of the helical thread 7 formed on the inner surface of the outer peripheral skirt 14, i.e. the beginning of the helical thread 7, rotates in a second direction opposite to the first direction of rotation. along, i.e., in the direction of rotation of the helical thread 7 about the axis X, the radial plane Pr located at 160° from the bisecting plane Pb, and an angular range S2 defined between the bisecting plane Pb be done. Accordingly, the cap 1 is easily fitted to the neck 2 of the container, since the lower front portion 25 of the peripheral skirt 14 is free of the helical thread 7 . This arrangement is particularly advantageous when the cap 1 can be in a slightly rearward position when in contact with the neck 2 of the container. This is particularly the case when there is no engaging element 18 in the front region 19 of the first part 16 and the lower ring 9 is able to move radially from front to back relative to the neck 2 of the container. apply.

Advantageously, the lower end of the helical thread 7 has two diameters located respectively at 90° and 160° from the bisecting plane Pb along a second direction of rotation opposite to the direction of the helical thread 7 of the cap 1 . It is arranged in an angular range defined between the directional planes.

On the other hand, at least one rib of the series of ribs of the helical thread 7 is formed on the inner surface of the heel 22, as schematically represented in FIGS. In other words, at least one rib of the helical thread 7 is formed between the two foils 11 , 12 of the hinge device 10 . The presence of said ribs formed in the heel 22 increases the resistance of the helical thread 7 to pressure and, particularly when the container is intended to contain carbonated beverages, excessive pressure on the container may cause the cap 1 to become detached. It is prevented from opening without

The kinematics of cap 1 are as follows. When unscrewed for the first time, the cap 1 leaves the closed position and moves away from the lower ring 9 to the released position shown in FIG. In the process of this movement, the fragility bridge breaks. Also during this unscrew movement of the cap 1 the lower ring 9 is rotationally driven about the axis X and the second portion 17 of the lower ring 9 moves in the direction of the cap 1 away from the engagement collar 5. Simultaneously rotate toward the raised position.

The cap 1 can then be rotated back towards the tilted open position with the peripheral skirt 14 extending upwardly from the top wall 13 . When the cap 1 rotates back towards the tilted open position, the stop 23 abuts the upper end of the second portion 17 of the lower ring 9, thereby lowering the second portion 17 of the lower ring 9 from the raised position. Rotate to position.

As shown in FIG. 9, the stop 23 bears against the engagement collar 5 when the second portion 17 of the lower ring 9 is in its lowered position and the cap 1 is in its tilted open position. Thus, the abutment of the stop 23 against the engagement collar 5 causes the cap 1 to move towards the release position facing the dispensing orifice 3 while the second part 17 of the lower ring 9 remains in the lowered position. The cap 1 remains in the tilted open position since it cannot be rotated by itself. This makes it possible to increase the minimum opening angle of the cap 1 . Advantageously, therefore, when the cap 1 is in the tilted open position and the second part 17 of the lower ring 9 is in the lowered position, the opening angle of the cap 1 is greater than 120°, advantageously 145° or more. Yes, for example about 180°. The opening angle corresponds to the protruding corner formed at the intersection of the plane parallel to the top wall 13 of the cap 1 and the horizontal plane.

To close the cap 1 again, the user tilts the cap 1 forward to the open position. During this tilting, the stop 23 abuts the engagement collar 5 and provides the second portion 17 of the lower ring 9 with a radially outwardly directed component that allows the lower ring 9 to move from the front to the rear. , and an axially upwardly directed component that makes it possible to assist the movement of the second portion 17 of the lower ring 9 to the raised position. The outer surface of the heel 22 also abuts the helical ribs of the helical thread 6, which also encourages movement of the second portion 17 of the lower ring 9 to the raised position.

When the second part 17 is in the raised position and the cap 1 is in the released position, the cap 1 can be screwed back onto the neck 2 of the container. During screwing, the lower ring 9 is rotationally driven about the axis X and the second portion 17 of the lower ring 9 rotates towards the lowered position as the cap 1 approaches the engagement collar 5 .

Advantageously, the entire capping device is molded in one piece from a synthetic material, for example polyethylene, preferably high-density polyethylene. Advantageously, the capping device is molded in the configuration of Figure 1, i.e. in the closed position, a position in which the capping device can be attached directly to the neck 2 of the container.
