Description

A CLOSURE DEVICE FOR CONTAINERS CONTAINING ASEPTIC LIQUID FIELD OF INVENTION The present invention relates to a closure device for aseptic paper or cardboard containers, which can be used for storing liquid products. In particular, the present invention relates to a closure device comprising three parts. It has a pouring spout that can be attached to an external surface of the container, a stopper having a resealable cap portion that is permanently connected to a retaining portion via a hinge, and a barrier-breaking device that is movably attached to the pouring spout and configured to break a liquid-tight seal / barrier of the paper or cardboard container after the stopper is rotated. The invention also relates to an assembly comprising an aseptic container and such a closing device, and a method for proportioning the assembly. In particular, the present invention relates to such an assembly wherein the container comprises a paper- or cardboard-based package. A paper-based package is sometimes referred to as a “box” and is commonly used to distribute consumable liquid products, for example, dairy products such as milk, or fruit juices. BACKGROUND OF THE INVENTION For boxes of sensitive food products, such as milk or juice, it is important that the closure device is carefully able to seal in order to be clean and hygienic and still be functional from the point of view of easy opening and closing of the pouring spout. A container or carton is typically produced from a laminated packaging material, which typically comprises a multi-fold sheet of paper or cardboard onto which one or more barrier layers are laminated for liquid containment and / or to prevent the migration of air and flavor-degrading substances through the carton. Typically, a barrier layer may comprise a polyethylene or aluminum layer. The pouring spout of the closure device can be attached to a location on the outer surface of the box, where a barrier is located on the box, which can be broken by a barrier breaking element in the closure device when the closure device is first opened. US 6851576 B2 describes a shutoff device in which a barrier rupture / piercing element moves helically toward the barrier, causing the barrier to fold away from the pouring spout, allowing liquid to be poured from the box into the pouring spout. WO 2010 / 109155 A1 and WO 2010 / 128302 A1 also describe a closing device having a rotary cutting device at the pouring spout, by which a hole can be formed through an area of ​​a box wall, allowing liquid to be poured from the box via the pouring spout. αζζρηη / ζζηζ / Ε / νίΛΐ One disadvantage of these closure devices known from the prior art is that the screw cap is removed from the closure device after opening the pouring spout to empty the liquid from the box, increasing the risk of users misplacing or losing the cap. Closure devices where a screw plug is retained in the closure device after opening the pouring spout to empty the liquid from the box are known in the field, which prevent users from incorrectly placing or losing the cap portion when operating the box, for example, when pouring the liquid from the box. US 2012 / 298,666 A1 describes a hinged closure / capping device for a packaging container having a long neck portion. The capper includes bridges to verify whether or not a screw-coupled capper is opened and a hinge portion where an internal concave groove is formed, thus allowing the stable connection of a capper body / lid and a locking ring to maintain a predetermined opening angle of the capper body in case of opening, in order to prevent the capper body from falling out and being altered, and thus elastically carrying out the opening and closing operations. US Patent 6,474,491 B1 describes a closure device comprising a stopper with a ring axially supported on that portion of the container, thus defining the container opening, and two arc-shaped limbs, each connected on one side to the stopper by means of a film joint and bendable parts, and on the other side to the ring. These limbs allow the stopper to tilt outward from the container for release from the container opening; however, the limbs are thin and easily damaged or deformed. The complex structure of the closure device makes manufacturing extensive. However, such closure devices where the screw plug is retained in the closure device after opening the closure device are not suitable for containers containing aseptic liquid, as a barrier of the box cannot be opened by the closure device. A first object of the present invention is to provide a closure device for an aseptic container wherein all parts are connected and / or connect interactively after the closure is first opened. A second object of the invention is to provide a locking device that indicates to a consumer whether the locking device has been previously opened, which may indicate that the product inside the container may be contaminated. A third object of the invention is to provide a liquid-tight sealing device that is easy to open and close, and less susceptible to damage and / or deformation. A fourth object of the invention is to provide a locking device that is simple and inexpensive to manufacture. A fifth object of the present invention is to provide a closing device which, when in an open position, does not interfere with the pouring operation. A sixth object of the invention is to provide a locking device that is easy to use by having improved opening and closing functionality compared to the prior art. οζζΑηη / ζζηζ / Ε / γίΛΐ BRIEF DESCRIPTION OF THE INVENTION The present invention provides a liquid-tight, hinged closure device for an aseptic paper or cardboard container, which can be rotated and folded, making it easy for the consumer. According to an exemplary aspect, the present invention provides a closing device comprising three parts: a pouring spout, a stopper, and a barrier breaking element. The peak discharge includes: - a central longitudinal axis that defines an axial direction z, a circumferential direction c and a radial direction r of the pouring peak, - an annular longitudinal neck portion extending along the axial z direction, from a first axial end to a second axial end defining a supply opening, the neck portion further comprising a first internal thread for interacting with the barrier rupture element and a second external thread for interacting with the plug; and - an annular flange portion for securing / fixing the locking device to the container, the annular flange portion extending in the radial direction r, outwards from the second axial end of the neck portion. The cap comprises: - an annular band of unalterable evidence that is retained around such a portion of the neck, - a retaining portion that is rotatably retained around such a neck portion, - a cap portion comprising an annular longitudinal skirt having an internal ramp, configured to interact with such second external threads of the pouring spout; - an articulation portion having a pivot axis around which the cap portion is configured to be rotatably movable relative to the retaining portion, the articulation portion permanently connecting the annular skirt of the cap portion to the retaining portion along a predefined circumferential extension, - a first breakable section along which the tamper-evident strip is configured to connect to the retention portion prior to a first opening of the locking device, the first breakable section being configured to be broken during the first opening and - a second breakable section along which the cap portion is configured to connect to the retaining portion before the first opening, the second breakable section being configured to break during the first opening, - wherein the cap portion is configured to be operable between a first position in which the cap portion hermetically covers such supply opening, a second position in which the cap portion non-hermetically covers the supply opening, and a third position in which the cap portion is located at least partially on one side of the supply opening. The barrier breaking element comprises: - a third external thread, configured to interact with the first thread of the pouring spout and - a barrier-breaking portion, configured to break the container barrier during the first opening. The second external thread of the pouring spout can occupy, in the axial z direction, a region located between a first plane and a second plane. The second plane can be located between the first plane and the second axial end of the pouring spout. Furthermore, the pivot axis of the articulation portion can be located in a third plane located between the first plane and the second axial end of the neck portion. When the cap portion is placed in the first closed position, the plug has a longitudinal central axis, corresponding to the longitudinal central axis of the pouring spout. Therefore, the plug may comprise an axial extension, which includes the axial extensions of both the annular longitudinal skirt and the retaining portion that extends between the first and second axial ends of the pouring spout. The articulation portion may be positioned in a so-called elevated position such that an axial extension of the retention portion, positioned below the articulation portion, may be from 100% to 200% longer than the axial extension of the retention portion positioned opposite the articulation portion in the circumferential direction, preferably from 100% to 150% longer. Furthermore, the retention portion may be dome-shaped beneath the articulation portion. This raised hinge portion allows for easier opening and closing of the lid portion, as it is more easily positioned around the pouring spout when operated by a consumer. If the hinge portion is not raised, the pouring spout may act as an obstacle, preventing the lid portion from being positioned correctly when operating the lid portion from the third to the second position. The third plane can be positioned between the first and second planes, or at or near the level of the second plane, or between the second plane and the second axial end of the neck portion. Additionally, the third plane of the pivot axis can be positioned parallel to the first plane Pi and the second plane P2. The pouring spout may also include a first and second retaining ring / bead ring. The first bead ring may be positioned between the flange portion and the second bead ring, which is configured to retain the tamper-proof annular evidence band. The second bead ring may be positioned between the first bead ring and the second thread, which is configured to retain the retention portion. The axial distance between the first ring of beads and the flange portion can define a first annular cavity of the neck portion for receiving and retaining the unalterable evidence band of the plug. The tamper-evident band can extend an annular 360° around the pouring spout when the closure device is assembled. Additionally, the first breakable section can also extend an annular 360° around the pouring spout. Therefore, after the stopper is rotated a predetermined distance around the pouring spout, the first tamper-evident band can be completely separated from the retaining portion. αζζΑηη / ζζηζ / Ε / γίΛΐ The first annular cavity may comprise a plurality of axially positioned ribs / supports, extending between the rim portion of the pouring spout and the first bead ring. Furthermore, the unaltered evidence band may comprise a plurality of bead sections extending radially toward the pouring spout when the locking device is assembled. The bead sections may be separated by grooves. Therefore, when the closure device is assembled, the grooves of the tamper-evident band may abut the ribs of the pouring spout, thus limiting the movement of the tamper-evident band in the circumferential direction c when the stopper is rotated, during the opening of the closure device for the first time, causing the connecting bridges of the first breakable section to break. In one aspect of the invention, the configuration of the unalterable evidence band and ribs may allow the cap portion to be rotated at a predetermined distance from any of: the range of 5° to 60° or 25° to 50° or 30°, such as, for example, 45° in the circumferential direction c, around the pouring spout, before the first breakable section breaks, disconnecting the unalterable evidence band from the retaining portion. The retaining portion can also be viewed as a second, tamper-evident band that serves two purposes. First, it retains the cap's retaining portion around the pouring spout after the closure device is opened. Second, it indicates to the consumer whether the closure device has been previously opened by means of this tamper-evident band. Before the closure device is opened for the first time, the retaining portion can be connected to the annular skirt portion of the cap by connecting bridges located in the second rupture section. These connecting bridges break the first time the closure device is opened. The second breakable section can extend along the circumferential direction c, between a first end point and a second end point of the hinge portion. Therefore, when the connecting bridges of the second breakable section break, the cap portion connects to the retaining portion only through the hinge portion. Such a predefined circumferential extension of the articulation portion can be found within any of: the range of 10° to 100°, 20° to 80°, and 30° to 65°. The second breakable section can have a circumferential extension within any of the range of 260° to 350°, 280° to 340° and 295° to 330°. Furthermore, the retaining portion may comprise a flexible, annular band positioned on the inner surface of the retaining portion, facing the pouring spout when the closure device is assembled. Before the stopper is assembled onto the pouring spout of the closure device, the flexible band may have a radial extension curving downwards, i.e., towards the undisturbed evidence band. After the stopper is assembled onto the pouring spout, the flexible band curves in the opposite direction, i.e., upwards, such that the flexible band abuts the second ring of beads of the pouring spout. This allows the retaining portion to orient itself freely over the pouring spout, such that the cap portion, when 077AΩη / 77η7 / B / YILI is in an open position, it can be oriented opposite to the direction of liquid pouring from the pouring spout, thus providing an open position that does not interfere with the pouring operation. The second external thread of the pouring spout may comprise a first section and a second section. The first section may extend within any of the following ranges: 250° to 340° or 280° to 330° and 290° to 320° in the circumferential direction and may have a helix angle of 0°. The second section may extend within any of the following ranges: 20° to 110° or 30° to 80° or 35° to 60° and 40° to 50° in the circumferential direction and may have a helix angle within any of the following ranges: 5.0° to 20.0° or 6.0° to 9.0° and 14.0° to 16.0°, such as, for example, 15°. The external thread may further comprise a third section that extends within any of the range of 250° to 340° or 280° to 330° and 290° to 320° in the circumferential direction and may have a helix angle of 0°. Furthermore, the external thread may comprise a fourth section extending within any of: the range of 20° to 110° or 30° to 80° or 35° to 60° and 40° to 50° in the circumferential direction and may have a helix angle within any of: the range of 5.0° to 20.0° or 6.0° to 9.0° and 14.0° to 16.0°, such as, for example, 15°. The fourth section may also be positioned parallel to and adjacent to the second section. The internal ramp of the cap portion of the plug may comprise a circumferential extension within any of: the range of 20° to 70° or 30° to 60° and 40° to 60°, such as, for example, 50°. In addition, the internal ramp can have a helix angle that falls within any of: the range of 5.0° to 10.0° or 6.0° to 9.0° and 7.0° to 8.0°. According to another exemplary aspect of the closure device, the first breakable section is configured to be broken, i.e., the connecting bridges of the same are broken before the barrier breaking element breaks the container barrier during the opening of the closure device for the first time. Additionally, the second breakable section can be configured to break after the barrier rupture element has broken the container barrier during the opening of the locking device for the first time. The barrier-breaking element may comprise rupture teeth, separated by slits positioned between the teeth, allowing the liquid inside the container to pass through the slits and into the pouring spout after the container barrier has been breached. Each tooth may further have a tip positioned at a first axial end of the barrier-breaking element. The tips are configured to interact with and break the container barrier when the locking device 1 is first opened. In another exemplary aspect of the present invention, the articulation portion can be positioned on the periphery of the annular skirt. The articulation portion can further comprise a central tangential point positioned at a circumferential distance within any of: the range of 150° up to 077AΩη / 77η7 / B / YILI 180° or 170° up to 180° and 175° up to 180° from a central tangential point of the ramp placed on the inner surface of the annular skirt portion. Additionally, the axial extension of the retention portion positioned below the articulation portion may be from 100% to 200% longer than the axial extension of the retention portion positioned opposite the articulation portion, preferably from 100% to 150% longer. Furthermore, the retention portion may be dome-shaped beneath the articulation portion. The articulation portion may have a butterfly configuration comprising a pair of separate trapezoidal ends, separated by a central portion. The central portion may have any shape, such as, for example, a rectangular structure. When the lid portion is flipped from the second to the third position, the hinge portion may deform slightly, thus locking the locking device in its third position. The butterfly hinge system can be adapted to deflect the lid portion away from the circumferentially positioned retaining portion when the locking device is in the open position. Therefore, the lid portion must be flipped back to the second position before the locking device can be rotated to the first position. The term “turn over” should be understood as an external force that needs to be applied to the lid portion to move the lid portion between the second and third positions. In a further aspect of the closing device, the second axial end of the pouring spout may comprise a sealing tab extending towards the central axis of the pouring spout. The sealing tab may be oblique in the direction towards the first axial end of the pouring spout. Furthermore, an end wall of the cap portion of the plug may comprise an annular longitudinal perforation seal having a common center axis with the annular longitudinal skirt, both extending in the same longitudinal direction and positioned such that the second axial end of the pouring spout is placed between the skirt and the perforation seal when the cap portion is in the first position. Furthermore, the radial extension of the sealing tab may be less than or equal to the radial distance between the inner surface of the longitudinal annular skirt and the perforation seal of the cap portion that provides a liquid-tight seal. The drill seal may have a gradually increasing longitudinal extension from a first point of the drill seal that is close to the articulation portion to a second point of the drill seal that is distant from the articulation portion. The perforation seal can also help guide and align the cap portion over the pouring spout when the cap portion is driven from the open / third position to the second position. The described embodiments of the closure device can be configured for use in a packaging container or liquid container comprising a multi-fold paper or cardboard sheet onto which one or a plurality of barrier layers can be laminated. 077AΩη / 77η7 / B / YILI Containment of liquid and / or prevention of the migration of air and flavor-degrading substances through the carton. Such liquid packaging containers are commonly used for the distribution of dairy products, for example, milk or juices. Typically, closure devices for such applications are made of polyethylene, and it is preferable that the closure device described in the invention be made of this material. The term “a first opening of the locking device” or “before the locking device is opened for the first time” should be interpreted as the arrangement of the locking device after assembly, for example, that neither of the breakable sections, first and second, has been broken. The term “first position of the lid portion” should be interpreted as the position just before the second breakable section breaks, therefore the position after the first breakable section has broken and after the barrier-breaking element has broken through the barrier and entered the box. The present invention also involves an assembly comprising a paper or cardboard container and a closure device, as described in any of the above-mentioned forms, attached thereto. Furthermore, the present invention involves a method for dispensing a locking device described in any of the above-mentioned forms, wherein the method comprises the steps of: - provide a pouring peak, - provide a stopper, - provide a barrier-breaking element and - mount such plug and barrier rupture element on such pouring spout. The stages of proportioning the pouring spout, plug, and barrier breaking element can be carried out by molding. The preferred and / or optional features described above for each aspect may be used, alone or in a suitable combination, in the other aspects of the invention.

DETAILED DESCRIPTION OF THE INVENTION Hereafter, the embodiments of the invention will be described in greater detail with reference to the figures. However, it is specifically intended that the invention not be limited to the embodiments and illustrations contained herein, but rather include modified forms of the embodiments that incorporate portions of the embodiments and combinations of elements from different embodiments, which fall within the scope of the following claims. It is appreciated that certain embodiments of the invention, which for clarity have been described above in the context of separate embodiments, can also be provided in combination in a single embodiment. Conversely, various features of the invention, which for brevity have been described in the context of a single embodiment, can also be provided separately or in any suitable subcombination. In particular, it will be appreciated that the features described in connection with one particular embodiment may be interchangeable with features described in connection with other embodiments. Figure 1 shows an exemplary embodiment of the closure device 1 of the invention. The closure device 1 has three parts: a pouring spout 100, a plug 200, and a barrier breaking element 700. A first exemplary modality of the 100 discharge spout is shown in Figs. 1, 3A and 8A, and a second exemplary modality of the discharge spout is shown in Figs. 13 and 14. Figs. 4 and 7 show the 200 plug in detail and Fig. 5 shows the 700 barrier rupture element in detail. Referring to Figs. 1 and 3A, the pouring spout 100 has an annular longitudinal neck portion 102 exhibiting an inner surface 124 and an outer surface 122. The neck portion 102 extends in an axial z direction (see Fig. 3B), and the inner surface 124 forms a channel 120 having a central axis Al positioned parallel to the axial z direction. Generally, the inner surface 124 is rotatably symmetric about the longitudinal central axis Al and defines a wall of the channel 120. The channel 120 forms a first axial base end 104 at the base of the pouring spout 100 and a second axial top end 106 at the top of the pouring spout 100. The first axial end 104 defines a first base opening 116 of the channel, and the second axial top end exhibits a second top opening 118 forming a supply opening 118 of the pouring spout 100. For convenience, the description below considers the term “upward” to correspond to an axial longitudinal direction z that is generally parallel to the central axis Al of the pouring spout 100 and extends from the first opening 116 to the second opening 118, while the term “downward” corresponds to the opposite direction. The terms “up” - “down,” “from above” - “base,” and “top” - “bottom” correspond to relative positions with respect to these directions, and the terms “internal” - “external” correspond to relative positions with respect to a direction perpendicular to this direction. At the first base end 104, the pouring spout 100 displays a radially extending, outwardly projecting annular flange portion 110, configured to be attached to a container, which may be in the form of a paper or cardboard box. For example, the flange portion may be welded onto an external surface of a box at a location where a barrier on the box can be easily breached by the barrier-breaking element 700. Both the internal surface 124 and the external surface 122 of the pouring spout 100 comprise a thread, namely a first internal thread 107 and a second external thread 108, respectively. The first thread 107 interacts with a third thread 708 positioned on the external surface 712 of the barrier-breaking element 700, see also Fig. 5. The second thread 108 of the pouring spout 100 interacts with the internal ramp 322 of the cap portion 300 of the plug 200 when the closing device 1 is opened and closed, see Fig. 7. The second thread 108 shows a first section 108a and a second section 108b. The first section 108a extends approximately 300° in the circumferential direction c, see Fig. 3B, and 077AΩη / 77η7 / B / YILI has a helix angle of 0°. The second section 108b extends approximately 60° in the circumferential direction and has a helix angle of 15°. Furthermore, the second thread 108 occupies, in the axial z direction, a region 109 located between a first plane Pi and a second plane P2. The first plane P1 is positioned at the level of a second bead ring 115. The second plane P2 is positioned between the first plane P1 and the second axial end 106. As shown in Fig. 2, the joint portion 500 of the plug 200 has a pivot axis Ap that allows the cap portion 300 to rotate about such pivot axis Ap. The pivot axis Ap is located at a third level P3, which, in Fig. 2, is at the level of the second level P2. P3 is illustrated in Fig. 4. The pouring spout 100 may have a sealing tab 112 positioned at the second axial end 106, shown in Fig. 8A. The sealing tab 112 may extend towards the longitudinal center axis Al of the pouring spout 100 in the radial direction r, improving the sealing properties of the closure 1. The sealing tab 112 can also be oblique in the direction towards the first axial end of the pouring spout. The radial extension of the sealing tab 112 may be less than or equal to the radial distance between the inner surface of the longitudinal annular skirt and a perforation seal of a cap portion of the plug 200 that is described in further detail with respect to Fig. 7. The first thread 107 has a helix angle of approximately 7°, although the helix angle can be selected from 5° to 15°, and occupies, in the axial direction, the entire inner surface of the pouring spout 100. The outer surface 122 of the pouring spout is provided with two axially offset bead rings 114, 115, referred to as the first bead ring 114 and the second bead ring 115. The first and second bead rings, 114, 115, are both annular and extend radially from the pouring spout 100. The first bead ring 114 is placed between the second bead ring 115 and the flange portion 110 of the pouring spout 100 and is placed at an axial distance, i.e., a distance in the axial z direction, from both the second bead ring 115 and the flange portion 110. The axial distance between the first bead ring 114 and the flange portion 110 defines a first annular cavity 126 of the neck portion 102 to receive and retain a first unaltered evidence band 450 of the plug 200. The annular cavity 126 has a plurality of ribs 129 shown as axially positioned supports, extending between the flange portion 110 and the first bead ring 114. Their function is discussed in further detail with reference to Fig. 8A. In addition, the axial distance between the first bead ring 114 and the second bead ring 115 defines a second annular cavity 127 of the neck portion 102 to receive and retain a second unalterable evidence band / retention portion 400 of the plug. Referring now to Fig. 1 and Fig. 4, the stopper 200 of the closure device 1 comprises the first tamper-evident band 450 and the retaining portion 400, the cap portion 300, and a hinge portion 500 that permanently connects the cap portion 300 to the 077ΑΩη / 77η7 / Β / ΥΙΛΙ retention portion 400. Cap portion 300 is configured to seal pouring spout 100 when in the closed position, preventing fluid from passing through it. Cap portion 300 comprises an end wall 321 and an annular longitudinal skirt 320 extending from the circumference of the end wall 321. The longitudinal skirt 320 has an internal thread / ramp 322 configured to interact with the external thread 108 that movably connects cap portion 300 from plug 200 to pouring spout 100. The annular skirt portion 320 has an external surface 324 comprising a plurality of parallel spines 328 to improve consumer grip. The retention portion 400 of the plug 200 is placed circumferentially around the neck portion 102, between the first unalterable evidence band 450 and the cap portion 300, when the cap portion 300 is in a closed position. The first tamper-evident band 450 is retained circumferentially between the first bead ring 114 and the flange portion 110 of the pouring spout 100. Before the locking device 1 is opened for the first time, the first tamper-evident band 450 is connected to the retaining portion 400 by a first breakable section 650, positioned between them. The first breakable section 650 comprises a plurality of connecting bridges 651 which, when the lock 1 is opened for the first time, will break such that the first tamper-evident band 450 and the retaining portion 400 are physically separated. The retaining portion 400 is connected to the cap portion 300 via a hinge portion 500 and a second breakable section 600 via connecting bridges 601, before the locking device is opened for the first time. The hinge portion 500 permanently connects the cap portion 300 to the retaining portion 400, although the connecting bridges 601 of the second breakable section 600 will break during the first opening of the locking device 1, after the first breakable section 600 has broken. However, the hinge portion 500 does not break during the opening of the locking device 1, allowing the cap portion 300 to rotate about the pivot axis Ap of the hinge portion 500, after the second breakable section 600 has broken, as shown in Fig. 1 and 2. When the locking device 1 is opened and the liquid inside the box can be poured out, the cap portion 300 rotates away from the supply opening 118, such that the cap portion 300 is located on the side of the supply opening 118 of the pouring spout 100. Thus, the cap portion 300 rotates away from the central axis Al of the pouring spout 100, around the pivot axis Ap far enough to allow almost unrestricted disposition of the contents through the supply opening 118 of the pouring spout 100, as shown in Fig. 2. The cap 200 is rotatable around the pouring spout 100 because the retaining portion 400 moves freely in the circumferential direction and thus allowing the consumer to move the cap portion 300 in the circumferential direction c, so that it is not in the path during pouring. Fig. 5 shows a detailed view of the 700 barrier breaker element being configured 077AΩη / 77η7 / B / YILI for breaking a box barrier on which the closing device 1 is fixedly positioned. Generally, the element 700 has an open-ended cylindrical geometry for coaxial placement within the pouring spout 100, as shown in Fig. 6. A barrier-breaking portion 702 having a plurality of teeth 709, each having a point 711, is positioned at a first axial end 704 of the element 700. The points 711 interact and break the box barrier when the closing device 1 is first opened. As shown in Fig. 5, element 700 has a third thread 708 positioned on its outer surface 712 that interacts with the first thread 107 of the pouring spout 100 when the closing device 1 is first opened. The third thread 708 is positioned above the barrier-breaking portion 702, occupying an area extending from a second axial end 706 to the barrier-breaking portion 702. When the closing device 1 is assembled, therefore, before it is first opened, the second axial end 706 of element 700 is positioned at or near the second axial end 106 of the pouring spout 100, preferably adjacent to the sealing tab of the pouring spout 100, as shown in Fig. 8A. Element 700 is thus completely closed by the neck portion 102 of the pouring spout 100 when assembled. The first and third threads, 107, 708, have a helix angle such that when the plug is rotated, and therefore when the closure is first opened, element 700 is displaced / rotated in the axial direction and in the circumferential direction c toward the case, i.e., away from the cap portion of the plug. Element 700 is rotated due to an interaction with the plug, which will be explained in more detail with reference to Figs. 8C and 9B below. The rotation of element 700 about the central axis A1 causes the prongs 711 to move through the case barrier by shearing off a segment of the barrier. The 711 tips are preferably shaped so as not to enter the box barrier, which can lead to tearing of portions into the box contents, but instead cut cleanly through a major segment of the barrier by pushing from a weakened area of ​​the barrier. Similar barrier-breaking elements are known in the field from, among others, WO 2010 / 128302 A1 and US 6,851,576, both of which are incorporated herein for reference. The weakened area of ​​the barrier may include, for example, a partial-depth cut, that is, a partially cut area that retains its barrier properties until it breaks. The partial-depth cut may be a half-circle cut, with the tips 711 of the toothed barrier rupture portion 702 interacting when the plug is first rotated. However, the tips 711 may travel a distance and push the half-circle cut portion of the barrier, causing it to break. The tips 711 may travel a total of less than 360°, preferably about 300°, when interacting with the half-circle cut portion, thus making a complete cut in the form of an open loop. Subsequently, the barrier rupture portion 702 enters the housing and pushes the barrier inward, as shown in Fig. 5 of WO 2010 / 128302 A1 and Fig. 4 of US 6,851,576. To ensure that the prongs 704 do not travel up to 360° in the circumferential direction, thus ensuring that the barrier does not fall and is directed towards the contents of the box, a segment / tooth 711 of the barrier-breaking portion may not include a prong 704. The barrier-breaking element 700 may further be positioned within the pouring spout 100, such that such segment 711 pushes the barrier to one side, inwards, so that the barrier does not interrupt or block the liquid during pouring from the box. As shown in Fig. 5, the teeth 709 are separated by slots 710. The slots 710 are positioned between the teeth 709 to allow the liquid inside the box to pass through the slots 710 and into the pouring spout 100 after the box barrier has been broken and, therefore, when the barrier-breaking portion 702 is positioned inside the box. Thus, the slots 710 ensure that the liquid is not blocked by the barrier-breaking portion 702 during the pouring of liquid from the box. Fig. 7 is a side view, in cross-section, of the plug 200 before it is assembled to the pouring spout 100. The cap portion 300 is open at its lower end and closed at its upper end by an end wall 321 which, on the outer periphery, shows an annular / tubular longitudinal skirt 320 extending axially downwards, the annular longitudinal skirt 320 being centered on a central axis Ac and having a circular base. The inner surface 326 of the annular skirt 320 has the inner ramp 322 which has a first tangential center point located approximately 170-180° from a tangential center point of the articulation portion 500. The inner ramp further has an extension in the circumferential direction c of approximately 30°. In the embodiment shown, the cap portion 300 is provided with an annular longitudinal perforation seal 310 that extends axially downwards from the end wall 321, such that it is centered on the central axis Ac, within the longitudinal skirt 320. Therefore, the annular longitudinal perforation seal 310 has a common central axis with the annular longitudinal skirt 320. Even if not shown, the perforation seal 310 may have a gradually increasing longitudinal extension, from a first point close to the hinge portion 500 to a second point farther from the hinge portion 500. The longitudinal extension of the perforation seal may be adapted to avoid any collision between the perforation seal 310 and the pouring spout sealing tab when the cap portion 300 is operated from the third / open position to the second position, as further described below with reference to Figs. 10, 11 and 12A to 12C. Figure 7 shows that the retaining portion 400 comprises an annular flexible band 405 extending downwards at approximately 45° on an inner surface 404 of the retaining portion 400 facing the pouring spout 100 when assembled. The flexible band 405 curves in the opposite direction to extend upwards at approximately 45° when the closing device is assembled as shown in Figure 8A. As shown in Fig. 8A, the flexible band 405 abuts the second bead ring 115 of the pouring spout 100, such that the retaining portion 400 is held between the first and second bead rings, 114, 115. The retaining portion 400 may have, instead of the band 077AΩη / 77η7 / Β / YILI flexible 405, a plurality of fins arranged in an annular manner, similar to the flexible band arrangement, thus having the same function. The first band of unaltered evidence 450 has a plurality of bead sections 455 that extend radially toward the pouring spout when the locking device is assembled. The bead sections 455 are separated by grooves 456 shown in Fig. 7. When the closure device 1 is assembled, as shown in Fig. 8A, the grooves 456 of the first tamper-evident band 450 abut the ribs 129 of the pouring spout 100, which constrains the first tamper-evident band 450 from moving in the circumferential direction c when the plug 200 is rotated during the initial opening of the closure device. Therefore, the connecting bridges 651 of the first breakable section 600 break when the plug 200 is first rotated; see also Fig. 8B, which shows the closure device 1 when assembled. The configuration of the grooves 456 of the unalterable evidence band 450 and the ribs 129 of the pouring spout 100 allow the plug 200 to be rotated around 10 to 60° before the first unalterable evidence band 450 is restricted in its movement and thus before the connecting bridges 651 of the first breakable section 650 are broken. Figure 8C shows a view from below of the assembled locking device 1, thus viewing the locking device 1 from the base opening 116 towards the top opening 118, which is covered by the cap portion 300. The cap portion has two cams, referred to as a first cam 340 and a second cam 342, also shown in Figures 1, 2, 7, and 8A. The first and second cams, 340 and 342, are configured to interact with the barrier-breaking element 700 when the locking device 1 is first opened. The barrier-breaking element has first and second protrusions, 740 and 742, positioned to interact with the first and second cams, 340 and 342, when the locking device 1 is first opened. The cams, first and second, 340, 342, are placed between the central shaft Ac, see Fig. 8B of the cover portion 300 and the perforation seal of the cover portion, and are separated by approximately 180° in the circumferential direction c. As shown in Fig. 8C, the first cam 340 is positioned to abut the first protrusion 740 and the second cam 342 is positioned to abut the second protrusion 742, so that the teeth 709 of the barrier-breaking element 700 can move out of the base opening 116. However, when the locking device 1 is assembled, there is no interaction between the first cam 340 and the first protrusion 740 or the second cam 342 and the second protrusion 742. The interaction between the ribs 129 of the pouring spout and the grooves 456 of the first unalterable evidence band 450, discussed above, causes the connecting bridges 651 of the first breakable section 650 to break before the cams, first and second, 340, 342, interact with the protrusions, first and second, 740, 742. This is to assure any consumer that the locking device 1 has not been opened if the connecting bridges 651 of the first breakable section 650 are not broken. Figure 9A shows the locking device 1 after the bridges of connection 651 of the first breakable section 650 have been broken. Therefore, the breakable section 650 provides, during the first opening, a clean break between the first unalterable evidence band 450 and the retention portion 400. Once broken, the first breakable section 650 provides evidence that the locking device 1 has been opened at least partially, thus providing the so-called “unalterable evidence.” After the connecting bridges 651 of the first breakable section 650 have broken, the first and second cams, 340 and 342, of the cap portion 300 engage with the first and second protrusions, 740 and 742, of element 700, respectively. This is shown in Fig. 9B, which shows the locking device 1 from the same view as Fig. 8C. As the plug continues to rotate to open the locking device, the first and second cams, 340 and 342, push the first and second protrusions, 740 and 742, such that element 700 is displaced in the axial direction and in the circumferential direction c, toward the housing.Due to the axial length of the cams, first and second, 340, 342, and due to the configuration of the second threads 108 of the pouring spout 100 interacting with the ramp 322 of the cap portion 300, the element 700 will be pushed, in the circumferential direction c, a length corresponding to the length of the first section 108a of the second thread 108, hence approximately 300°. Figure 10 illustrates the closing device 1 after the plug 200 has been rotated approximately 300° after the cams, first and second, 340, 342, have engaged with the protrusions, first and second, 740, 742, thus showing that the barrier-breaking portion 702 protrudes from the first base opening of the pouring spout 100; therefore, the box barrier has been broken and the barrier-breaking portion 702 has entered the box. Furthermore, it is shown that the connecting bridges 651 of the first breakable section 650 have been broken, while the connecting bridges 601 of the second breakable section 600 are still intact. When the cap portion 300 is still connected to the retaining portion 400 in this position, the cap portion 300 is referred to as being in the first position Pf. Fig. 11 illustrates the closing device 1 after the plug 200 has been rotated further to open the cap portion 300 of the closing device 1. Due to the configuration of the second threads 108 of the pouring spout 100 interacting with the ramp 322 of the cap portion 300, the cap portion 300 of the plug has been pushed in the circumferential direction cy and upward in the axial direction z, a length corresponding to the length of the second section 108b of the second thread 108, being approximately 60°. Therefore, the connecting bridges 601 of the second breakable section 600 break as the retaining portion 400 is held by the second bead ring. The cap portion 300 is now ready to be flipped about the pivot axis Ap shown in Figs. 1, 2, 12B and 12C, because the joint portion 500 fixes the cap portion 300 to the retaining portion 400.In this position, the portion of lid 300 is referred to as being in a second position Ps. The second breakable section 600 provides, during the first opening, a clean break between the retaining portion 400 and the part of the cap portion 300 that is not articulated to the retaining portion 400. Once broken, the breakable section 600 provides evidence that the locking device 1 has been fully opened, thus providing unalterable evidence. Figs. 12A to 12C illustrate the flipping operation of the lid portion 300, all showing cross-sectional side views of the same locking device 1. In Fig. 12A, the plug 200 has already been rotated along the first section 108a of the second thread 108, and therefore the barrier-breaking portion 702 of the barrier-breaking element 700 has been moved into the housing. The connecting bridges of the second breakable section 600 are thus ready to be broken; therefore, the configuration of the locking device is the same as that described in Fig. 10. However, the cap portion 300 is placed in the first position Pf. In Fig. 12B, the cap portion 300 has been separated from the retaining portion 400 along the second breakable section, but is attached to the retaining portion 400 by a hinge portion 500. The cap portion 300 has also been partially flipped into a position intermediate between the second position Ps and a third position / supply position Pt shown in Fig. 12C. Therefore, Fig. 12B illustrates the same position of the cap portion shown in Fig. 1. Fig. 12C shows the lid portion placed in the third Pt position, allowing the contents of the box to be easily poured out through the supply opening of the pouring spout 100, as also illustrated in Fig. 2. As shown in Figs. 12A to 12C, the retaining portion 400 has a longer axial extension, where the hinge portion 500 is fixed to the retaining portion 400, compared to the other side of the retaining portion 400 from which the contents of the container from the closing device 1 can be poured out. In this way, the hinge portion 500 is raised, which is also illustrated in Fig. 15. The axial extension of the retaining portion is approximately 120% longer than the length of the axial extension of the retaining portion 400, positioned opposite the hinge portion 500. Fig. 13 shows a pouring spout 100 according to a second exemplary embodiment of the invention, and Fig. 14 shows the pouring spout 100 placed inside a closing device 1. The only difference between the first and second exemplary embodiments of the pouring spout 100 is the thread configuration; therefore, the remaining parts of the pouring spout are as described for the first exemplary embodiment and will therefore not be repeated for the second exemplary embodiment. The second 108 thread shows a first section 108a and a second section 108b, a third section 108c, and a fourth section 108d. The first section 108a extends approximately 330° in the circumferential direction and has a helix angle of 0°. The second section 108b extends approximately 60° in the circumferential direction and has a helix angle of approximately 15°. The third section 108c extends approximately 300° in the circumferential direction and has a helix angle of 0°, and the fourth section 108d extends approximately 60° in the circumferential direction and has a helix angle of approximately 15°. The first and third sections, 108a, 108c, are placed in parallel, close to each other, offset in the axial z direction to allow the ramp of the cap portion to interact with the first and / or third sections 108a, 108c of the second thread 108 when the plug is turned. αζζΑηη / ζζηζ / Ε / γίΛΐ The second section 108b and the fourth section 108d are placed parallel to and close to each other, offset in the axial z direction, to also allow the ramp of the cap portion to interact with the second and / or fourth section 108b, 108d when the cap is rotated. The second thread 108 occupies, in the axial z direction, a region 109 located between a first plane Pi and a second plane P2. The first plane Pi is placed adjacent to and above the second bead ring 115. The second plane P2 is placed between the first plane Pi and the second axial end 106. As shown in Fig. 14, the assembly of the closing device is the same as shown for the first pouring spout mode in Fig. 1. Figure 15 shows an exemplary embodiment of the articulation portion 500 having a butterfly articulation system comprising a pair of separate trapezoidal ends 502, 504, separated by a central portion 506, the central portion 506 having a rectangular shape that may have folded longitudinal edges. The butterfly articulation system is adapted to deflect the cap portion 300 away from the circumferentially positioned retaining portion 400 when the locking device 1 is in the open position, as shown in Figure 2. Figure 15 further illustrates end points 602, 604 of the breakable section 600, which are separated by the hinge portion 500. It can be observed that the circumferential extension of the retaining portion 400 under the hinge portion 500 shows a curved shape extending upwards in the direction of the hinge portion 500, such that the retaining portion 400 is domed under the hinge portion 500. The domed area of ​​the retaining portion 400 can have a circumferential extension, in the circumferential direction c, from approximately 30° to 100° of the total circumference of the retaining portion 400. However, the retention portion 400 may have different shapes than the dome-shaped structure shown under the articulation portion, allowing the pivot axis Ap to be placed in the third plane P3 located between the first level Pi and the second axial end of the pouring spout 100. Generally, with respect to Fig. 1 to 15, the cap portion 300 is resealably placed over the pouring spout 100. The ramp 322, see Fig. 7, of the cap portion 300 is configured to interact with the external thread 108 of the pouring spout 100, allowing the cap portion 300 to be turned / rotated around the central axis A1 of the pouring spout 100 and detached by twisting / screwing from the pouring spout 100, driving the closing device 1 from a first / closed position, see Fig. 10, to a second position where the cap portion 300 does not hermetically cover the supply opening 118, see Fig. 11, and is rotated over the pouring spout 100, driving the closing device 1 from such second position to the first / closed position. In the second position, the central axis Ac of the longitudinal annular skirt 320 of the lid portion 300, is different from the central longitudinal axis Al of the pouring spout 100. When the closing device 1 is moved from the first / closed position to the second position, the cap portion 300 is rotated until the ramp 322 is released to a position that does not interact with the external thread 108, such that the cap portion 300 can be moved away from the pouring spout 100, to the third position, by flipping / rotating the cap portion 300 around the pivot axis Ap of the articulation portion 500, allowing the contents, for example a liquid, to be supplied through the supply opening 118 of the pouring spout 100, see Fig. 2 and 12C. Figure 16 shows an example of a box 50 comprising the closing device 1 where the lid portion 300 is in a third open position. As can be seen, the flange portion 110 of the pouring spout 100 has been fixed to the outer surface of the box 50, which can be done, for example, by hot air or ultrasonic welding. With respect to all figures, the following sequential steps allow a user to open the locking device 1, from the assembled position to the third / open position: a) providing the locking device 1 in a closed assembled position, b) rotating / turning the cap portion 300 of the plug 200 approximately 45° in a counterclockwise direction, having a helix angle of 0° until the connecting bridges 651 of the first unalterable evidence band 650 are broken, c) rotating the lid portion 300 approximately 300° further at a helix angle of 0° until the barrier-breaking element 700 has broken the barrier of box 50 and the barrier-breaking portion 702 has been permanently placed inside box 50, thereby placing the lid portion 300 in a first position Pf, d) continue rotating the cap portion towards the second position Ps, approximately 60°, such that the second section 108b of the external thread 108 and the internal ramp 322 force the cap portion 300 to separate from the retaining portion 400 along the second breakable section 600, thereby breaking the connecting bridges 601 and then, e) Turn the cap portion 300 around the pivot axis Ap towards the third position Pt, so that the supply opening 118 of the pouring spout 100 opens to supply the liquid from the box 50. In addition, the following steps allow the user to close the closing device 1 from the start from the third / open position. d) turn the lid portion 300 back to the pouring spout 100 towards the second position Ps, e) Turn the plug 200 clockwise until the sealing device 1 is liquid-tight.
