Description

Technical field

The invention relates to a device for capping a container and an assembly comprising a container equipped with such a capping device.
The invention relates more particularly to a capping device that makes it possible to keep a cap attached to the neck of a container, thus avoiding losing the cap in nature.

Background art

In the state of the art, there are known capping devices that make it possible to keep a cap attached to a neck of the container. A capping device of this type is described, for example, in document US2018086510 in the name of the applicant.
The capping device comprises a ring that is intended to be retained on the neck of the container, a cap that is intended to cover the orifice of the container to seal it, two elastic sheets that join the cap with the lower ring and a locking device installed to lock the cap in a tilted open position.
Such capping device is not fully satisfactory. In particular, this cap is intended to snap fit into the neck of the container and cannot be adapted to other types of neck. Furthermore, the movement of the cap between the closed position and the tilted open position is a simple pivot movement, which limits the height of the cap and / or neck that can be used. This limits the applications of said capping device. In particular, it is not suitable for containers intended to receive carbonated beverages because the pressure inside such containers would lead to unwanted openings of the cap.
Otherwise, the locking device is not adapted for all types of cap and does not ensure sufficient reliability to maintain the tilted open position in screw caps, for example.

Description of the invention

One idea on which the invention is based is to propose a capping device that allows keeping a cap attached to the neck of the container that is easy to manufacture and use and that allows the cap to be kept in the tilted open position in a reliable and robust manner.
According to one embodiment, the invention provides a capping device, intended to be fixed to a neck of a container in order to seal an orifice of said neck, said neck comprising an engaging collar, the capping device comprising:

a cap comprising an upper wall and an outer peripheral skirt, the cap being suitable to be arranged in a closed position in which the upper wall seals the orifice in the neck and the peripheral skirt surrounds said neck;
a ring located under the cap in the closed position and comprising a first section intended to be axially retained in the engaging collar of the neck and a second section, the first section and the second section of the ring being articulated to each other in such a way that the second section pivots with respect to the first section from a lowered position to a raised position to allow the cap to move axially away from the neck from the closed position to a released position in which said cap is no longer inside the neck of the container; and
an articulation device that connects the cap to the second section of the ring, the articulation device being configured to allow the cap to pivot along an axis of rotation between said released position and an open tilted position in which the cap is disconnected from the orifice of the neck;

By virtue of these features, the capping device makes it possible to propose a cap that can remain attached to the neck with the help of the ring and the articulation device. The articulation of the ring allows, for its part, to adapt the capping device to long necks, for example, for the use of a cap to be screwed on. Otherwise, the male fixing element and the female fixing element allow providing a robust locking device that adapts to any type of cap, for example, that is to be screwed or snap fit.
Furthermore, the arrangement of the lug in the housing and its orientation relative to the heel allow the tilted open position to be robustly maintained.
Finally, since the second section of the ring is not very susceptible to deformation, the relative position of the female fixing element with respect to the articulation device is constant, which makes it possible to ensure a precise positioning of the male fixing element with respect to the female fixing element. during the pivoting of the cap towards its tilted open position.
According to some embodiments, a capping device of this type may comprise one or more of the following features.
According to one embodiment, the housing comprises a beveled lower part that forms said lower surface.
According to one embodiment, the lug and the heel extend parallel to the axis of rotation.
The lug and the heel thus form a snap-fit connection made in the same direction as the axis of rotation, thus, it is referred to as a horizontal snap-fit. Unlike a vertical snap fit, for example, such a snap fit allows for a better grip in the tilted open position due to its orientation relative to the kinematics of the cap. Otherwise, because the snap-fit extends in this direction, the grip is further improved.
By "extending in one direction" is meant that the largest dimension of the element is formed in this direction.
According to one embodiment, the male fixing element comprises a main portion connecting the lug to the outer peripheral skirt of the cap, the lug and the main portion being inclined relative to each other to form a hook.
In this way, the hook shape of the male fixing element allows better retention in the housing of the female fixing element when the cap is in the tilted open position.
According to one embodiment, the capping device is made by molding with the help of two half-shells that are joined at the level of a radial joint plane, the male fixing element of the cap and the female fixing element of the ring being made each one on both sides of said joint plan.
In this way, the design of the capping device allows an unmolding with a mold with two half-shells without leaving any residues.
According to one embodiment, the joint plane is oriented to pass through a central axis X of the capping device and through the center of the articulation device.
According to one embodiment, the male fixing element of the cap is formed in line and centered above the articulation device.
According to one embodiment, the female fixing element of the ring is formed in line and centered below the articulation device.
According to one embodiment, the articulation device comprises a deformable sheet connecting the outer peripheral skirt and the second section of the ring.
In this way, the deformable sheet has the function of a hinge by elastic deformation thereof during the movement of the cap from the released position towards the tilted open position.
According to one embodiment, the deformable sheet comprises a predetermined pivot area configured so that the axis of rotation of the capping device is located in this predetermined pivot area.
According to one embodiment, the predetermined pivot area is made with the aid of a zigzag portion of the deformable sheet.
According to one embodiment, the first section and the second section are separated from each other by two thin areas in which the ring locally has a radial thickness decrease to allow the second section to articulate with respect to the first section.
According to one embodiment, the ring is intended to be mounted movably in rotation on the neck around a central axis X of the capping device and the outer peripheral skirt of the cap has a helical thread intended to cooperate with a helical thread provided on the neck of the container to allow screwing or unscrewing of the cap on the neck around the central axis X.
According to one embodiment, the ring comprises a notch configured to locally deflect the ring from the engaging collar, the notch being diametrically opposite to the articulation device, and the cap comprises a closing element that protrudes axially from the outer peripheral skirt and that it is diametrically opposite to the articulation device, the closing element being intended to cooperate with the engaging collar provided on the neck to position the closing element in the notch and to keep the cap in the closed position.
According to one embodiment, the lower ring is connected to the outer peripheral skirt by frangible bridges.
According to one embodiment, the second section extends over the entire height of the ring.
According to one embodiment, the second section extends over an angular range comprised between 120 and 200°, and preferably comprised between 160 and 190°.
According to one embodiment, the articulation device is connected to the second section in a central area of the second section.
According to one embodiment, the capping device is made by molding in a single piece.
According to an embodiment, the invention also provides an assembly comprising a container equipped with a neck comprising a engaging collar and an orifice, and equipped with a capping device mentioned above, the first section of the ring of the capping device being retained axially into the engaging collar of the neck.
According to one embodiment, the first section comprises one or more retaining elements that project radially towards the interior of the ring; they are arranged below the engaging collar and are configured to axially retain the ring on the neck of the container.
According to one embodiment, the housing is delimited downwards by a lower surface against which the lug is intended to be supported during the movement of the cap towards the tilted open position, which makes it possible to exert a downwardly directed force on the ring and which allows the second section of the ring to be brought back to the lowered position where it is aligned with the first section.

Description of embodiments

In the description and the figures, the X axis corresponds to a central axis of the capping device intended to be positioned orthogonally to the plane of the orifice to be sealed when the capping device is in the closing position and seals said orifice. The X axis thus corresponds to the axis of rotation of the cap of the capping device when it is screwed onto the neck of the container. By convention, the "radial" orientation is orthogonal to the X axis. The terms "external" and "internal" are used to define the relative position of an element with respect to another, by reference to the X axis, an element close to the X axis is thus qualified 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 in the neck is directed upwards and the cap is in a closed position on the neck of the container, an element intended to be positioned lower being designated as lower element and an element intended to be positioned higher being designated as upper element.
With reference to Figures 1 to 5, a capping device 1 according to one embodiment is described. The capping device 1 is intended to be assembled on the neck 2 or throat of a container, as shown in Figures 1 to 4. The container is, for example, a bottle.
The capping device 1 comprises a so-called tamper-evident ring 3 that is intended to be retained on the neck 2 of the container, a cap 4 that is intended to cover the orifice 5 of the container to seal it and an articulation device 6 that joins the cap 4 with the lower ring 3. Furthermore, the capping device 1 also comprises a locking device composed of a male fixing element 7a formed in the cap 4 and a female fixing element 7b formed in the ring 3, the locking device 7a, 7b being arranged to lock the cap 4 in a tilted open position, shown in Figures 3 and 4, wherein the cap 4 is disengaged from the orifice 5 of the container and does not hinder the pouring of the contents of the container.
The capping device 1 is made by molding with the help of two half-shells that are joined at the level of a joint plane, as well as a mold that is placed on top of the half-shells. The half-shells make it possible to mold, in particular, the peripheral skirt 9 and the ring 3, while the mold allows the upper wall 8 of the capping device 1 to be molded. The joint plane is oriented to pass through the X axis of the capping device 1 and through the center of the articulation device 6.
The ring 3 is held axially in the neck 2 of the container by means of an engaging collar 18, in particular, represented in Figures 1 to 3. The engaging collar 18 has a frusto-conical external surface that tapers upwards, that is, in direction of the orifice 5 of the container. The engaging collar 18 delimits, downwards, that is, in a direction opposite to the orifice 5, a projection.
The cap 4 comprises an upper wall 8 intended to be arranged substantially orthogonal to the axis X, opposite the orifice 5 of the neck 2 when said cap 4 is in the closed position. The cap 4 further comprises an outer peripheral skirt 9 intended to surround the neck 2 of the container when the cap 4 is in the closed position. The outer peripheral skirt 9 extends, downward, perpendicular to the upper wall 8, from the outer periphery of said upper wall 8.
In the illustrated embodiment and as represented in Figures 6 and 7, the outer peripheral skirt 9 has, on its internal face, a thread 10 formed by a series of helical ribs and intended to cooperate with a complementary thread 11, that is visible, specifically, in Figures 2 and 3, formed by a series of helical ribs, and provided on the external surface of the neck 2. In this way, the cap 4 is suitable to be screwed onto neck 2 in order to close the container and to be unscrewed from the neck 2 in order to open the container. The cap 4 is thus movable between the closing position, represented in figure 1, and a released position, represented in figure 2. In said released position, the cap 4 is no longer inside the neck 2 of the container. In this way it is suitable to be tilted towards the open tilted position, shown in Figures 3 and 4, wherein the cap 4 is released from the orifice 5 of the neck 2 so as not to hinder the pouring of the contents of the container.
According to another embodiment, not shown, the cap 4 is not screwed onto the neck 2, but is snap fit onto it. Ring 3 comprises a notch configured to locally deflect the ring 3 from the engaging collar 18. The notch is diametrically opposite to the articulation device 6. The cap 4 comprises a closing element which projects axially from the outer peripheral skirt 9 and which is also diametrically opposite to the articulation device to be in line with the notch in the closed position. The closing element comprises a projection directed towards the inside of the cap 4 at one end of the closing element and which is intended to cooperate with the engaging collar 18 provided on the neck 2 to position the closing element in the notch and to maintain the cap 4 in closed position. Indeed, during the step of the engaging collar 18, the projection generates the elastic deformation of the closing element to return to its initial state after having passed the engaging collar 18 and thus maintain the cap 4 with respect to the neck 2 in the closed position in the form of a snap-fit connection.
As represented, for example, in Figures 1 and 2, the outer peripheral skirt 9 has, on its outer face, a series of grooves distributed around the X axis and extending parallel to said X axis. The grooves thus provide a rough surface that facilitates the grip of the cap 4 by the user or by the assembly device of the bottling chain.
The cap 4 also comprises an internal skirt 12, represented in particular in Figure 4, which extends perpendicularly downward from the upper wall 8 of the cap 4 and is sized to be inserted inside the orifice 5 of the neck 2. The cap 4 also comprises an annular lip 13, also visible in figure 4, which extends, from the upper wall 8, radially between the inner skirt 12 and the outer peripheral skirt 9. The inner skirt 12 and the annular lip 13 are sized in such a way that, when the cap 4 is in the closed position, on the neck 2 of the container, the inner skirt 12 is in contact against the inner face of the neck 2, while the annular lip 13 is in contact against the outer face neck 2. In this way, the inner skirt 12 and the annular lip 13 make it possible to ensure the sealing of the closure.
In the illustrated embodiment, the ring 3 is connected, before the first opening of the container, to the cap 4 by frangible bridges 14, visible in Figure 1, intended to break during the first opening of the cap 4. These frangible bridges 14 constitute, in this way, tamper-evident signs, hence the term tamper-evident ring 3. More particularly, the frangible bridges 14 are distributed around the axis X and connect the upper edge of the ring 3 and the lower edge of the outer peripheral skirt 9.
According to another embodiment, not shown, the ring 3 and the cap 4 are connected to each other by means of a tearable strip which is interposed axially between the cap 4 and the ring 3 and which is connected, on the one part, to the lower ring. 3 by frangible bridges and, on the other part, connected to the cap 4 by other frangible bridges.
The ring 3 is held axially on the neck 2 of the container while being able to rotate with respect to it about the axis X. The ring 3 comprises two parts that are articulated to each other, namely a first section 15 and a second section 16 at the level of which the ring 3 is connected to the cap 4 by means of the articulation device 6. The ring 3 comprises two thin areas 17, that is, the radial thickness of which is less than the radial thickness of the ring 3 outside of said thin areas 17. The two thin areas 17 delimit the first section 15 and the second section 16. The thin areas 17 thus form pivots that allow articulation of the second section 16 with respect to the first section 15.
The cap 4 can thus move from the closed position illustrated in Figure 1 to the released position illustrated in Figure 2 by moving axially away from the first section 15, which generates the inclination of the second section 16 in an increasingly inclined position with respect to the first section 15 as the cap 4 is opened to reach an inclined position of the second section 16 with the cap 4 in the released position. Otherwise, when the cap 4 passes from the released position to the tilted open position illustrated in figure 3, the second section 16 returns to its original position aligned with the first section 15.
The first section 15 of the ring 3 comprises retention elements 19 that cooperate with the engaging collar 18 provided on the container in order to axially retain the ring 3 on the neck 2 of the container. The retaining elements 19 are protrusions, visible in figure 6, which protrude radially inward from the first section 15 of the ring 3.
The second section 16 of the ring 3 comprises a clamping element 20 that cooperates with the engaging collar 18 provided on the container in order to axially maintain the ring 3 on the neck 2 of the container in the closing position of the cap. As it is visible in figure 7, the clamping element 20 is a protrusion that protrudes radially inward from the second section 16 of the ring 3, below the articulation device 6. However, unlike the retention elements 19, the clamping element 20 is designed so that, from the moment the cap is moved from the closed position towards the released position, the clamping element 20 is ejected from under the engaging collar 18 in order to allow the second section 16 to pivot with respect to the first section 15.
The articulation device 6 is configured to allow the cap 4 to pivot between the released position, represented in Figure 2, and the tilted open position, represented in Figures 3 and 4. In the embodiment shown, the articulation device 6 comprises a single deformable sheet 21 that connects the cap 4, and more particularly the outer peripheral skirt 9 of the cap 4 to the second section 16 of the ring 3. The deformable sheet 21 acts as a hinge by elastic deformation of the latter during the pivoting of the cap 4 and is positioned in the center of the second section 16. Advantageously, the deformable sheet 21 is attached to the outer peripheral skirt 9 in a recessed portion, so that the deformable sheet extends above the lower limit of the outer peripheral skirt 9.
Furthermore, the deformable sheet 21 comprises a predetermined pivot area 22 configured so that the axis of rotation of the capping device is located in this predetermined pivot area 22. In the embodiment illustrated, specifically, in FIG. 1, the predetermined pivot area 22 is made with the help of a zigzag portion 23 of the deformable sheet 21 which ensures that the axis of rotation is located in this area.
In another embodiment represented in Figures 6 and 7, specifically, the deformable sheet 21 that forms the articulation device 6 is formed differently from the embodiment in Figure 1. Indeed, in this embodiment, the deformable sheet 21 has been reduced in height and increased in width to make sheet 21 stronger and more rigid than in the previous embodiment. Furthermore, the deformable sheet also includes a predetermined pivot area 22, which is made herein with the aid of lateral edges of the deformable sheet that have a flared portion 24. Indeed, the pivot area 22 is thus made at the level of the section of the deformable sheet 21 which is located at the beginning of the flared portion 24.
Furthermore, the narrowing in height of the deformable sheet 21 makes it possible, as can be seen in Figure 7, to preserve two levels of threads 10 that allow the cap 4 to better anchor to the neck during uncapping, for example. Finally, in this embodiment, the size in the radial direction of the male fixing element 7a has been increased to increase the grip of the cap 4 in the tilted open position.
In another embodiment, not shown, the deformable sheet 21 may comprise a lower thickness in the pivot area 22 in the radial direction compared to outside the pivot area 22.
As described above, the locking device is composed of a male fixing element 7a formed on the cap 4 and a female fixing element 7b formed on the ring 3. The male fixing element 7a of the cap 4 and the female fixing element 7b of the ring 3 cooperate with each other to keep the cap 4 with respect to ring 3 in the tilted open position illustrated in figures 3 and 4.
As this can be seen more precisely in figure 5, the male fixing element 7a comprises a main portion 71 protruding radially from the outer peripheral skirt 9, a first end of the main portion 71 being connected to the outer peripheral skirt 9, and also comprises a lug 72 connected to the main portion 71 at a second end of the main portion 71 opposite the first end. The lug 72 and the main portion 71 are inclined with respect to each other in a radial plane passing through the male fixing element 7a so that the male fixing element 7a is in the form of a hook. The male fixing element 7a is thus formed in line and centered above the articulation device 6. Furthermore, the male fixing element 7a is made to be formed on both sides of said joint plane in order to facilitate molding of the capping device 1.
The female fixing element 7b comprises a housing 73 provided on the ring 3 and a heel 74 made on an outer surface of the ring 3. The heel 74 is designed to partially cover the housing 73 by projecting axially downward. Thus, at the level of the housing 73, an internal wall of the ring 3, the housing 73, then the heel 74 is located from the inside to the outside of the ring 3.
During the movement of the cap 4 from the released position to the tilted open position, the lug 72 is in front of the housing 73 at the level of the heel 74, then it is inserted after elastic deformation of the male fixing element 7a to the passage of the heel 74 in the housing 73. The lug 74 thus protrudes axially upwards when the cap 4 is in the tilted open position and is retained by the lug 74 thus forming a stop in the housing 73. Preferably and in order to facilitate insertion of the lug 72 into the housing 73, the housing 73 comprises a beveled lower portion 75.
The male fixing element 7a and the female fixing element 7b are made so that their greatest size is formed parallel to the axis of rotation of the capping device 1. In this way, the cooperation of the male fixing element 7a with the female fixing element 7b forms a long snap fit in this direction, more efficient for maintaining the tilted open position of the cap 4.
On the other hand, the housing 73 is delimited downwards by a lower surface against which the lug 72 is intended to be supported during the movement of the cap 4 towards its tilted open position, which makes it possible to exert a downward force on the ring 3 and allows the second section 16 of the ring 3 to be brought back into the lowered position.
Advantageously, the assembly of the capping device results from a single-piece molding of synthetic material, such as polyethylene and advantageously high-density polyethylene, for example. 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.
Although the invention has been described in relation to several particular embodiments, it is more than evident that it is not limited to them in any way and that it comprises all the technical equivalents of the described means, as well as their combinations if they fall within the scope of the invention.
The use of the verb "comprise", "comprising" or "consisting of" and their conjugated forms does not exclude the presence of other elements or of other steps different from those stated in a claim.
In the claims, any reference signs in parentheses are not to be construed as limiting the claim.
