Definitions
- the present invention is a stopper-type closure for containers that comprises means to reveal a first opening, the closure is preferably coupled to the mouth of a container, for example a bottle.
- the present invention is characterized by a closure that comprises an internal stopper and an external stopper interrelated with each other so that they allow a distance to be set between them once the first opening of the closure occurs. This distancing generates a visual change in the appearance of the closure, showing the first opening.
- the present invention combines, among others, a slot with a helical section with a projection that moves through said slot until it reaches a housing where its movement is irreversibly blocked by means of of a flexible extension.
- the displacement of the projection along the slot defines the transition between a first position before the first opening and a second position after the first opening of the closure.
- Closures with means to prevent tampering or fraudulent refilling of the contents of bottles or containers are of great interest in the marketing of high value beverages. As it can be for example the bottles destined to liquors.
- the means of evidencing the first opening can be of a different nature. For example, there are closures that make use of breakable bridges joining two parts that separate after the closure is first opened. One of these parts can be, for example, a ring that detaches exposing a part of the closure that was not previously visually accessible.
- the changes that a closure undergoes to show the first opening do not necessarily have to be visual but can make use of other senses. For example they can be sound. This is the case when there are elements fixed by means of some type of fastening that, after the first opening, although they may continue to be housed, for example, in a certain cavity, may have a clearance that makes it sound when the closure is moved, or it sounds in a certain way. distinct.
- the projections that advance along the guide, upon reaching the perpendicular change of direction, are housed in a space that prevents the projection from advancing in either direction.
- the movement that this housing allows gives rise to an axial displacement that is not continuous and that can be reversed by looking for the reverse movement.
- the second solution gives rise to configurations that are complex to execute and with reduced reliability since the anchoring of the teeth is not always produced properly and the configuration of the ratchet is not strong enough.
- the present invention is a closing element that allows to solve the previous problem by means of a certain configuration and combination of components that ensures the evidence of the first opening, the internal mechanisms are not accessible from the outside to avoid manipulation and, the resistance to forced she's very tall.
- the invention solves the previously identified problems with a closure for first-open evidence containers according to claim 1. Specific embodiments of this closure are defined in dependent claims.
- a first inventive aspect of the invention defines a closure for containers with evidence of first opening configured to be coupled to the mouth of a container along an axial direction X-X'.
- the axial direction X-X' is the main longitudinal direction of the mouth of the container and also the main direction that the closure or stopper itself follows when it is attached to the mouth of the container.
- Positional and orientation terms such as superior, inferior, deep zone, etc. will be used. These terms positions should be interpreted with respect to the orientation that a container adopts with its mouth located in the upper part, where the closure is placed.
- the present closure comprises: an inner stopper that comprises: a main body; an internal thread complementary to a thread either of the mouth of the container or of a pourer; fixing means adapted to be fixed to the container; breakable means adopted to link the main body and the fixing means, where these breakable means are adapted to break when in operating mode a preset torque between the main body and the fixing means is exceeded;
- an outer plug configured to at least partially house the main body of the inner plug
- the invention proposes for the closure an internal stopper that is formed by a main body, an internal thread complementary to a thread on the mouth of the container or a spout, fixing means that allow it to be fixed to the container, and breakable means that link the main body with the fixing means; and an outer plug that is exposed to the outside and houses the main body of the inner plug at least partially inside it.
- the internal thread of the internal cap is arranged inside the main body and is configured to complement a thread on the mouth of the container or a spout. That is, the inner stopper is configured to be threadedly coupled to the mouth of a container or pourer by means of said internal thread.
- the inner stopper comprises fixing means arranged at a lower end of this inner stopper so that the main body of the inner stopper is initially fixed to the container. These fixing means allow the closure as a whole to be fixed through the inner stopper to the container.
- the inner cap comprises breakable means that link the main body with the fixing means and when in operating mode a pre-established torque applied between the main body and the fixing means is exceeded, these breakable means break.
- Breakage of the breakable means is indicative of a first use or first opening of the container.
- the breaking of the breakable media generates a sound that is already a form of first opening evidence in addition to those that will be described later.
- the closure allows screwing and unscrewing around the mouth of the container or pourer by means of the aforementioned internal thread of the internal cap. . Therefore, between the main body coupled to the mouth of the container or spout and the fixing means fixed to the container are interposed the Breakable means that establish a temporary union that will be relevant in the opening process that will be described later.
- the fixing means can define a direct fixing between the inner stopper and the container or they can define a fixing of the inner stopper to the container by means of other intermediate components.
- the outer plug that covers at least partially the main body of the inner plug and protects it from the outside.
- Both the inner plug and the outer plug mainly have a cylindrical configuration extending along the axial direction X-X'.
- cylindrical configuration is generally understood any configuration whose main side wall is the result of the rotation of a generatrix around a directrix extended along the axial direction X-X'.
- this generatrix is a straight line parallel to the axis of rotation coinciding with the axial direction X-X', giving rise to a cylinder with a circular and constant section, at least the main structure of each respective stopper.
- the present closure is characterized in that a first part, either the internal stopper or the external stopper, comprises a projection directed towards a second part different from the first part, either the external stopper or the internal stopper. That is, the closure is configured as a first and second piece, each of which can be either the internal stopper or the external stopper, respectively.
- the second piece comprises: at least one slot with a helical section along the axial direction XX' configured to guide the trajectory of the projection of the first piece in such a way that a relative rotation between the first piece and the second piece imposes a mutual axial displacement X-X'; a housing for the projection; an elastically deformable extension configured to restrict the section of the slot in at least a part of the helical section, with a section smaller than that required for the passage of the shoulder in such a way that, in operative mode, the forced passage of the shoulder causes bending of the elastically deformable extension; and where the configuration of the groove is such that, after reaching the highlight the housing, the flexible extension partially or totally elastically recovers its initial position, irreversibly blocking the exit of the shoulder from the housing.
- the slot arranged in the second piece guides the projection of the first piece when both first and second pieces rotate relative to each other, this relative rotation causing the displacement of both first and second pieces according to the axial direction X-X' .
- the groove has a helical section in the axial direction X-X'.
- the helical configuration of the slot will be understood as a configuration in which the trajectory of the slot establishes a guide of the projection that causes a relative movement between the first part and the second part made up of one turn plus one. axial displacement. Since the preferred configuration of the groove is on the cylindrical side surface of the first body or the second body, the groove is in the form of a helix with rotation and advancement in the axial direction X-X'.
- the slot comprises a housing configured to receive the protrusion of the first piece where, preferably, the housing is located at one end of the slot.
- the section of the groove in question is restricted by means of an elastically deformable extension in at least part of the helical section of the groove itself. This restriction in the section of the slot provides a section smaller than that necessary to allow the passage of the projection through the slot.
- the elastically deformable extension In operative mode, when the projection is forced to pass through the slot by the reduced section, the elastically deformable extension is caused to flex. Once the projection reaches the seat after having traveled the helical section of the slot as a result of the relative rotation between the first part and the second part, the elastically deformable extension elastically recovers its initial position, irreversibly blocking the projection from coming out of the slot. accommodation and therefore that the first piece and the second piece return to the original position before the first opening.
- the torque required for the forced passage of the shoulder through the slot causing the bending of the elastically deformable extension is less than the torque required to break the frangible means.
- This torque difference means that the rupturable media does not rupture at the initial stage of opening.
- the passage of the shoulder through the reduced section, forcing the bending of the elastically deformable extension requires a force that has to support the breakable means without these break ensuring that the piece attached to the container does not move.
- the projection Once the projection has reached its seat, it releases the flexible extension so that it recovers its position.
- the position of the housing is at the end of the end of the slot in such a way that the projection reaches the end of the slot.
- the first piece and the second piece comprise two extreme positions.
- This position corresponds in operating mode to the state prior to exerting the torque that causes the forced passage of the projection through the slot towards the housing. Therefore, the projection is located in the groove in a position distant from the mentioned housing so that there is still no gap between the first part and the second part. This position is the one with the projection in the cap assembly and therefore before the first opening.
- the second position is established once the closure is opened for the first time, that is, when the necessary torque has already been applied so that the projection is in the seat after having overcome the retention imposed by the elastically deformable extension in the slot. . It is just after reaching this second position that the subsequent breakage of the breakable means occurs.
- the forced passage of the projection along the groove towards the housing causes the elastically deformable extension to flex allowing the passage of the projection, and it is due to its elastically deformable configuration that this extension resumes its position of retention (initial or rest position) once said protrusion overcomes this retention running through the slot until it reaches the housing arranged at one end of the slot.
- the fact that the extension recovers its deformation-free state ensures that the projection remains in the housing and thus prevents it from going back through the slot, since it retains its movement, limited by the presence of the extension that prevents it from going back.
- the first part and the second part are axially spaced apart compared to the first position, which results in an irreversible axial separation between the first and second part.
- this gap between the first and second part that occurs in the second position provides evidence of the first opening of the present closure so that this gap between the first and second part is visible from the outside of the closure.
- the distance between both pieces gives visual access to an annular section that was not visible before.
- the passage from the first position to the second position as explained, a movement is achieved between the first and second parts that is visually accessible and evidences a first opening of the closure.
- this visible evidence of the distance between the first and second pieces it can be known just by visualizing the closure that it has been previously opened.
- the color of the surface that is initially hidden and visually accessible after the first opening is different from the outer surfaces of the stopper, evidencing the first opening to a greater degree.
- first and second pieces are irreversibly separated from each other with means that are not accessible from the outside prevents manipulation of the mechanisms that ensure irreversibility, so that it is advantageously possible to keep the closure in place.
- second position of both pieces thus evidencing a first opening of the closure.
- the first part is the internal stopper and the second part is the external stopper. That is, the groove configuration with a housing at one end and an elastically deformable extension is provided on the outer plug while the projection is provided on the inner plug.
- the passage from the first position of the closure to the second position by positioning the projection in the housing causes the outer plug to distance itself axially from the inner plug and as a consequence, this distance is visually observed, evidencing a first opening of the closure.
- the torque necessary to break the breakable means of the closure and for this closure to reach the mentioned second position, is applied to the outer plug with respect to the inner plug.
- the cap descends axially until it reaches the stop, for example, ensuring tightness with the spout, but in no case is the distance that is evident from the first opening reduced again.
- the elastically deformable extension comprises a complementary configuration of at least one part of the shoulder adapted to rest on the shoulder when it is in the housing and such that it establishes a support with flexural retention of the elastically deformable extension.
- This particular configuration of the elastically deformable extension rests on a part of the projection in such a way that it retains it in the housing in the second position.
- the support on the projection by means of a part with a complementary configuration ensures a coupling that generates a retention that prevents the movement of the end of the elastically deformable extension in the trajectory of the arch, thus ensuring to a greater degree the irreversibility of the second position.
- the forcing from the second position to the first position gives rise to a compressive stress of the elastically deformable element.
- a failure could occur due to buckling, endangering the stability of the second position.
- Increasing the slenderness of the elastically deformable extension can be caused by the reduction in the torque necessary to cause its deformation by bending, making it easier for the user to open.
- the complementary configuration portion with the shoulder increases the stability of the support and reduces the risk of buckling of the elastically deformable element.
- the assembly formed by the groove and the projection is hidden, preferably by a capsule that covers the external stopper.
- this capsule protects the groove and projection assembly and keeps it hidden under said capsule, thus avoiding tampering since the attempted destruction of the cap or access to the mechanism would be evidenced.
- the closure additionally comprises a capsule that comprises a lower skirt and an upper portion to cover at least part of the external stopper where: the breakable means are configured by means of a ring with a perimeter projection; the lower skirt is notched to retain the frangible means perimeter flange for affixing the frangible means to either a spout or container.
- the rupturable means comprise a ring with a perimeter projection that is retained to a pourer or container by means of the notched edge of the lower skirt of the capsule that exerts a retention force on said ring.
- the rupturable means is located between the perimeter rib ring and the remainder of the plug.
- the ring is secured to the pourer or container so that when sufficient torque is exerted on the closure, the breakable means break as a result of the rotation of the upper skirt of the capsule (and with it dragging both the inner and outer caps). ).
- the applied torque causes the upper skirt of the capsule together with the inner and outer caps to rotate with respect to the perimeter ring after yielding the breakable means that are fixed to the pourer or container by means of a half ring fixed by the lower skirt of said capsule.
- both skirts of the capsule are they are in contact and one following the other, however, in the second position a distance is provided not only between the outer plug and the inner plug but also between the upper skirt of the capsule and the lower skirt. This is a consequence of the fact that the first skirt, as has been said above, partially covers the outer cap and the lower skirt covers a pourer or the container, holding the perimeter ring of the breakable means.
- the closure comprises a pourer configured to be coupled to the container that comprises: an external thread complementary to the internal thread of the internal cap; a skirt adapted to engage the container.
- the spout comprises an external thread on which the internal cap is screwed through its own internal thread, in this way the internal cap (and consequently also the internal cap) are fixed to the spout.
- the container does not need to have the thread configured.
- the spout comprises a skirt in its lower part, that is to say, below its external thread, through which it allows the spout to be coupled to a container or container mouth. Therefore, this pourer allows the coupling of the present closure to a container or bottle to allow evidence of a first opening thereof, minimizing the possibility of manipulation of said closure.
- the pourer comprises a pouring surface and the inner stopper a complementary extension adapted to rest on the pouring surface to establish a tight seal between the two.
- a tight seal is advantageously established between the inner plug, in particular its main body, and the pourer. In this way it is prevented that the content of the container that flows through the spout passes inside the internal stopper. Since the distance between the inner plug and the outer plug generates a greater elevation of the outer plug, the interaction between the inner plug and the spout is not affected by the solution that evidences the first opening.
- the closure comprises a valve to prevent fraudulent refilling of the container. Thanks to this valve, manipulation of the interior of the container or bottle on which the present closure is coupled is avoided and therefore the refilling fraudulent of them.
- the inner cap comprises a first upper surface transverse to the axial axis X-X' that shows at least one upper housing radially distanced from the center established by the axial axis of rotation X-X';
- the outer plug comprises a second upper surface transverse to the axial axis X-X' that shows at least one support projection radially spaced from the center established by the axial axis of rotation X-X' the same distance as the upper housing of the first upper surface; where: in the first position between the first part and the second part, the support projection is housed in the upper housing and, in the second position between the first part and the second part, the support projection is in contact with the first transverse upper surface and outside of the upper housing.
- the upper housing of the inner plug is understood as a groove arranged towards the inside of the inner plug itself.
- the support projection is understood as a projection that protrudes from the upper surface of the outer stopper towards the interior of the same, that is to say, oriented towards the outer surface of the inner stopper.
- the joint configuration of the upper housing on the internal stopper and the support projection on the external stopper ensures the distance between the two parts, the external stopper and the internal stopper, when moving from the first position to the second position. That is to say, this configuration makes the closure robust and ensures its purpose, which is to demonstrate a first opening of the closure without the option for this to be manipulated.
- One way to manipulate the first opening evidence mechanism is to apply an axial force that overcomes any retention mechanism that maintains the gap between the outer plug and the inner plug.
- the support projections are housed in the housings of the inner cap before the first opening and, after the first opening, with the relative rotation of the internal cap with respect to the exterior, the projections remain outside the housing and rest directly on the upper surface of the cap. inner stopper. This support absorbs the axial forces without being transmitted to the rest of the elements that ensure the spacing evidenced by the first opening.
- the at least one upper housing of the inner stopper comprises a depth that decreases from the upper surface of the inner stopper to the deepest point of said upper housing, so that when moving from a first position to a second position the at least one support projection of the outer cap moves along the upper housing from the deepest point of the upper housing until it reaches the upper surface and is outside the upper housing.
- the upper housing arranged in the inner plug has a depth that varies decreasingly from the upper surface of the inner plug towards the deepest point of this upper housing.
- the passage from the first position to the second position caused by a necessary torque that causes a gap between the inner plug and the outer plug causes the support projection of the outer plug to slide or at least not be hindered in its movement along from the upper housing until it rests on the upper surface of the inner plug.
- the closure is made up of a plurality of upper recesses on the upper surface of the inner cap and a plurality of support projections on the outer surface of the outer cap that are complementary to said recesses.
- the support projections are housed respectively in the upper housings.
- the support projections are in contact with the first transverse upper surface of the inner stopper and outside said upper housings.
- one or more projections are located in a position where the diameter is maximum, leaving the housings open towards the side wall of the inner stopper. By being located in more distant positions according to the radial direction, the angular displacement of the projection is also greater.

- the present invention describes a closure device for containers with evidence of a first opening.
- This closure is configured to be coupled to the mouth of a container or bottle or pourer according to an axial direction X-X'.
- Figures 1A-IB show an elevation view of the closure where, in particular, the comparison can be seen between a first position of the closure in which a first opening has not occurred, and a second position of the closure in which it is evident that there has already been a first opening of it.
- the closure comprises an inner plug (1) and an outer plug (2) as main components.
- the inner stopper (1) is formed by a main body (1.1), an internal thread (1.2) that is complementary to the mouth of the container or to a spout (6); and fixing means (1.3) that fix the inner stopper (1) to the container.
- the inner plug (1) comprises breakable means (1.4) that link the main body (1.1) of the inner plug (1) and the fixing means (1.3).
- the breakable means (1.4) break when in operating mode a preset torque between the main body (1.1) and the fixing means (1.3) is exceeded.
- the outer plug (2) partially houses the main body (1.1) of the inner plug (1).
- the closure also comprises a capsule (5) formed by a lower skirt (5.1) and an upper portion (5.2) that covers the outer cap (2).
- the breakable means (1.4) of the inner cap (1) are configured by means of a set of breakable bridges and comprise a lower ring with a perimeter projection (1.3.1) that is retained by means of the lower skirt (5.1) that is notched to thus keeping the ring of the fixing means (1.3) fixed to a pourer (6) or container.
- the internal plug (1) corresponds to a first part of the closure and the outer cap (2) to a second part. That is, the internal stopper (1) (as shown in Figure 6) comprises a plurality of projections (3) that protrude from the internal stopper (1) towards the outside thereof.
- the outer plug (2) comprises a plurality of grooves (4), in particular, as many as projections (3) comprises the inner plug (1).
- figures 2-4 show how the grooves (4) have a helical section (4.1) according to the axial direction X-X', and this groove (4) is configured to guide the path of the projection (3) of the inner plug (1). Therefore, a relative rotation between the inner plug (1) and the outer plug (2) imposes a mutual axial displacement X-X'.
- a housing (4.2) located at one end of the helical section (4.1) is shown, which is intended to receive the projection (3) that moves through its corresponding slot (4).
- Each slot (4) also has an elastically deformable extension (4.3) configured to restrict the section of the slot (4) in at least part of the helical section (4.1). In particular, the slot (4) has a smaller section than that required for the passage of the projection (3).
- Figures 2 to 4 show a sequence of movement between the inner plug (1) and the outer plug (2) during the initial phase in a first opening of the closure.
- Figure 2 shows a first position of the closure in which the projections (3) are housed in the slot (4) at an opposite end to where the housing (4.2) is located, while the extensions (4.3) elastically deformable are in a state of rest, that is, without undergoing any bending stress. This is the position and configuration of the cap when, after its manufacture, it is installed in the bottle before the first opening.
- Figure 3 shows an intermediate position of the closure as its first opening is carried out, in which it can be seen how the projection (3) has moved to along the slot (4) towards the housing (4.2) forcing the extension (4.3) to flex so that it allows it to pass through the helical section (4.1) of the slot (4).
- the extension (4.3) is slightly bent, in this case upwards, while the projection (3) presses it to allow movement through the helical section (4.1) of the slot (4).
- Figure 3 shows a movement transition of the closure between the first position and the second position.
- Figure 4 shows a second position of the closure in which the projections (3) have reached the housing (4.2) after having traveled the helical section (4.1) of the slot.
- the extension (4.3) has elastically recovered its initial position and is irreversibly blocking the exit of the projection (3) from the housing (4.2).
- the first position (figure 2) describes a position of the closure before the first opening where the projection (3) is in the groove (4) in a position distant from the housing (4.2).
- the second position (4) describes a position of the closure after the first opening in which the projection (3) is in the housing (4.2) after passing through the section of groove (4) restricted by the elastically deformable extension (4.3).
- the torque required for the forced passage of the projection (3) through the slot (4) causing the bending of the elastically deformable extension (4.3) is less than the torque required to break the breakable means (1.4).
- the breakable means therefore have a sufficient resistance so that the inner cap (1) remains attached to the fixing means (1.3) and ensures the retention so that the bending of the elastically deformable extension (4.3) occurs.
- the user continues to apply a torque that now exceeds the resistance of the breakable means (1.4) since the projections (3) rest on the walls of the housing (4.2) completing the opening of the cap and allowing the assembly formed at least by the inner stopper (1) and the outer stopper (2) are separated from the container. Now, with this distanced position, the inner plug assembly (1) and the outer plug (2) are locked together and behave as a single body.
- the elastically deformable extension (4.3) comprises a configuration that is complementary to at least a part of the projection (3) on which the projection (3) rests when it is in the housing (4.1). ).
- the extension (4.3) includes at its free end, on which the projection (3) rests in the second position, an "L"-shaped configuration that partially embraces the projection (3) when it is in the housing. (4.2) from the groove (4).
- this support with complementary shapes stabilizes the compression conditions of the elastically deformable extension, minimizing the possibilities of buckling in the event of a forced attempt to recover the first position.
- Figure 5 shows a perspective view of the closure in an intermediate position during the first opening of the closure as detailed above for figure 3.
- the outer cap (2) comprises a second upper surface (2.1) transversal to the axial axis X-X' and completely smooth.
- Figures 7 to 10 show a pourer (6) that comprises an external thread (6.1) that is complementary to the internal thread (1.2) of the internal cap (1), which allows the internal cap (1) to be threaded to the weir (6); and a skirt (6.2) suitable for coupling to a container.
- the pourer (6) also includes a pouring surface (6.3) on which rests an extension (1.5) of the inner plug (1) as seen in detail in figures 9 and 10, in order to establish a tight seal between the pouring surface (6.3) and the extension (1.5) of the inner plug (1).
- figures 9 and 10 show a valve (7) to prevent fraudulent refilling of the container on which the present closure is arranged. This valve (7) remains closed when the container is in a vertical position with the spout (6) facing upwards to prevent fraudulent refilling.
- FIG. 6 shows the closure without the outer plug (2), that is, only the inner plug (1) is shown.
- This internal plug (1) comprises a first upper surface (1.6) transversal to the axial axis X-X', four upper housings (1.6.1) radially spaced from the center established by the axial axis of rotation X-X'.
- the upper housings (1.6.1) of the inner plug (1) have a variable height that decreases from the upper surface (1.6) of the inner plug (1) to the deepest point of said upper housing (1.6.1). That is, the base of each upper accommodation
- the image on the right shows a perspective bottom view of an outer plug (2) of the closure.
- the outer plug (2) comprises a second upper surface (2.1) transversal to the axial axis X-X' that shows two support projections (2.1.1) (of the four that have this configuration) radially distanced from the center established by the axis of axial rotation X-X'.
- the support projections (2.1.1) are radially spaced the same distance as the upper housings (1.6.1) of the first upper surface (1.6) of the inner stopper. That is, the configuration of the support projections (2.1.1) of the inner plug is complementary to the upper housings (1.6.1) of the inner plug.
- This complementary configuration means that in the first position between the outer plug (2) and the inner plug (1) the support projections (2.1.1) are housed in the upper housings (1.6.1), while in the second position the support bosses
- each support projection (2.1.1) are in contact with the first transverse upper surface (1.6) and outside the upper housing (1.6.1). That is, the passage from the first position to the second position causes each support projection (2.1.1) to move, for example sliding, along the respective upper housing (1.6.1) until it is positioned on the upper surface ( 1.6) of the inner plug (1).
- the arrangement of these support projections (2.1.1) resting on the upper surface (1.6) ensures and maintains the distance between the outer plug (2) and the inner plug (1) blocked against an axial effort with the intention of forcing the rest of the set.
- Figures 2 to 5 show how the outer cap (2) comprises a plurality of grooves (2.3) that facilitate its grip.
- the upper portion (5.2) of the capsule (5) that is arranged on the outer cap (1) and comprises a toothed configuration (5.3) in only one part of this upper portion (5.2) as can be Observe in Figures 1A-1B.
- This portion in a toothed configuration (5.3) of the capsule (5) has been obtained in this embodiment by notching the capsule by plastic deformation on the groove (2,3) of the external cap (2).
- the upper portion (5.2) of the capsule (5) does not rotate according to the outer plug (2) since the toothed configuration (5.3) offers a retention against rotation to the grooves (2.3) of the outer plug (2).
- the toothed configuration (5.3) of the capsule (5) makes it easier for the user to grip the closure.
- Figure 6 shows how the inner cap (1) also includes four perimeter housings (1.7) in the form of a slot with a ramp configuration in the least part of its displacement. These perimeter housings (1.7) are complementary to the supports (2.2) that are arranged inside the outer plug (2) as can be seen in figure 7, in the image on the right.
