专利说明:

The invention relates to a screw cap with at least one first orientation means for forming a closure device. Furthermore, however, the invention also relates to an orientation tool with at least one second orientation means.
A generic trained screw cap for forming a closure device and a cooperating orientation tool describes WO 2016/116344 A1. The screw cap is used to close a threaded neck of a container. The screw cap comprises a cap body with a cap wall and a circumferentially formed, apron-shaped side wall. The side wall has an outer surface and an inner surface and protrudes from the cap wall. Furthermore, the side wall ends in an open end region with a front end, on which a guarantee strip is subsequently arranged. The guarantee strip is used to prove the originality of the medium recorded in the recording room. At least one thread is arranged or formed on the inner surface of the side wall of the cap body. For oriented alignment of the screw cap, this has at least one arranged on the cap wall and projecting into the cap cavity first orientation means. The orientation tool comprises a body part and an associated upper end portion for receiving the screw cap. The orientation tool further comprises at least a second orientation means, which is arranged on the end face of the upper end portion. The disadvantage here is that the pressure force applied during the orientation process between the orientation tool and the inner surface of the cap wall has also been applied to the at least one first orientation means arranged there until reaching the orientation position, which leads to a deformation of the first orientation means and a not always reliable orientation result has led.
The object of the present invention was to overcome the disadvantages of the prior art and to provide a screw cap for forming a closure device and an orientation tool, by means of which a user is able, a simple and secure orientation of the screw cap for the subsequent Aufschraubvorgang make.
This object is achieved by a screw cap and an orientation tool according to the claims.
The screw cap according to the invention serves to form a closure device which serves to close containers which have a neck with at least one thread turn arranged or formed thereon. The screw cap may comprise at least the following components: a cap body having a cap wall and having a circumferentially formed skirt-like sidewall, which sidewall defines a longitudinal axis and bounded by an outer surface and an inner surface, the sidewall protruding from the cap wall and at its side from the cap wall averted side having an open front end, at least one thread with a threaded start and a circumferentially spaced therefrom arranged threaded end, which at least one thread on the inner surface of the side wall of the cap body is arranged or formed, a guarantee strip which guarantee band in the region of the open front end of the side wall is arranged, wherein the guarantee strip is connected by means of a plurality of predetermined separation points at least partially separable from the side wall, at least a first orientation means, wherein the at least one first orientation means on the guarantee strip is ordered or trained.
The advantage achieved thereby is that by arranging or providing the orientation means on the guarantee strip a spatial distancing from the inner surface of the cap wall can be achieved. Thus, a planar support can be created on the cap wall, which serves for support on the end face of the orientation tool. Since the peripheral side wall of the cap body and the guarantee strip subsequently arranged on the side wall have a certain elasticity and a circumferential preload force upon stretching, the orientation process of the screw cap on the orientation tool can be carried out even more simply and safely. The guarantee strip, in turn, has sufficient hoop strength to securely engage and abut the second orienting means provided on the orientation tool. Furthermore, the one or more arranged on the guarantee strip and projecting in the direction of the longitudinal axis of the first orientation means can also additionally improve the latching engagement with a securing flange on the neck of the package body. As a result, an improved retention effect and, associated therewith, a safer separation of the guarantee strip during the first opening process from the neck can be ensured.
Furthermore, it may be advantageous if the guarantee strip is folded after production of the screw cap from a projecting in the axial direction over the open front end manufacturing position in a direction of the longitudinal axis directed securing position. As a result, the arrangement and shaping of the guarantee strip can be carried out more easily and a sufficiently secure originality position can be created.
Another embodiment is characterized in that the guarantee strip protrudes in the securing position in an angular orientation against the cap wall. Thus, a secure engagement can be ensured with a securing flange provided on the neck.
Another possible embodiment has the features that the at least one first orientation means in the production position in the radial direction on the side facing away from the longitudinal axis on the guarantee strip is projecting and protrudes in the securing position in the radial direction against the longitudinal axis. Thus, the demolding and training of the first orientation means on the guarantee strip can be facilitated.
A further embodiment provides that the at least one first orientation means is formed as a projecting extension and the extension has a first stop surface projecting over the guarantee strip in the radial direction on the longitudinal axis, which first stop surface forms a stop edge with the surface of the guarantee strip and on the from the guarantee strip averted side ends with a body edge. By forming the first orientation means as an extension with a stop edge delimiting the stop face, a secure engagement position with the cooperating second orientation means on the orientation tool can thus be created.
Another embodiment is characterized in that the first stop surface has a triangular shape and the stop surface bounding the first stop surface, together with the body edge starting from the guarantee strip, forms the triangular shape in the direction of the cap wall. As a result, the Entformbewegung facilitated and accidental shearing and damaging the formed as an extension first orientation means can be prevented.
A further preferred embodiment is characterized in that the stop edge in a view in the axial direction in the cap interior has a projected on a normal plane to the longitudinal axis longitudinal axis, which projected longitudinal course has a direction parallel to a reference plane extending orientation, wherein the reference plane through the axial direction and the radial direction is stretched. By the parallel displacement of the projected longitudinal course of the stop edge, an even better engagement effect between the cooperating orientation means can be created.
Furthermore, it may be advantageous if the first stop surface encloses an acute angle with the surface of the guarantee strip. By forming an acute angle, an undercut can be formed so as to ensure a secure engagement between the respectively cooperating orientation means in the orientation position. In this way, skipping in the course of the rotational orientation movement between the orientation means arranged on the orientation tool and on the guarantee strip of the screw cap can be prevented.
Another alternative embodiment is characterized in that the extension is formed starting from the body edge in the direction of the guarantee strip sloping. As a result, in the case of an opposite rotational movement of the orientation tool, an easier skipping of the first orientation means via the second orientation means on the orientation tool can be made possible.
Another possible and optionally alternative embodiment has the features that the at least one first orientation means is formed as a recess o-the recess in the guarantee strip and the recess or recess forms a further stop surface. By providing a recess or depression in the guarantee strip, a sufficient and reliable orientation effect can also be created with the second orientation tool provided on the orientation tool.
A further embodiment provides that at least one partial section of the stop face and the thread start of the at least one thread turn are arranged in a common axial plane extending through the longitudinal axis. Thus, the relative position of the first orientation means relative to the thread start in the course of the orientation process can be determined and determined.
Another embodiment is characterized by the fact that the at least one thread, starting from its thread beginning in the circumferential direction, extends to the side facing away from the stop face to its threaded end. Thus, an oriented orientation of the screw cap can be determined during axial alignment for the screwing on the neck and spent in the required and predetermined joining position with the neck.
A further preferred embodiment is characterized in that three threads and the same number of first orientation means are provided on the inner surface of the side wall, which threads and first orientation means are each distributed uniformly over the circumference. By providing a plurality of threads as well as a plurality of orientation means, the maximum necessary orientation travel and the associated relative swivel angle between the orientation tool and the screw cap can thus be reduced. As a result, a faster orientation process can be achieved, whereby the efficiency of the joining device can be improved.
However, the object of the invention can also be solved independently by the features of claim 14 concerning an orientation tool. The orientation tool is used for the front-side receiving and placing a screw cap, wherein the orientation tool can also be referred to as orientation stamp. The orientation tool may comprise at least the following components: a cylindrically shaped base body, which base body defines a longitudinal axis, an orientation section, which orientation section is arranged on an end area of the base body and the orientation section has at least one second orientation means, wherein the at least one second orientation means interacts with at least one first orientation means of the screw cap is used, and - the orientation section has a directed in a vertical direction with respect to the longitudinal axis end face, and further - the at least one second orientation means on an outer peripheral surface of the orientation section and arranged in the axial direction distanced from the end face or formed ,
The advantage achieved by this is that, by forming the orientation tool opposite to one another and the screw cap to be oriented thereon, a spatial separation from the pressure force acting on the cap inner wall can also be created starting from the end face of the orientation section and the second orientation means. As a result of the axial distancing and the circumferential arrangement of the second orientation means on the outer circumference of the orientation section, the inherent strength and elasticity of the guarantee strip for the engagement of the cooperating orientation means in a positive sense can also be exploited. Furthermore, but also a more planar pressure transmission from the end face of the orientation section towards the inner surface of the cap wall can be achieved.
Furthermore, it can be advantageous for the at least one second orientation means to have an orientation surface extending in a parallel direction with respect to a reference plane, which reference plane is spanned by the axial direction and the radial direction, and that the orientation surface in the axial direction comprises an upper boundary edge and a lower boundary edge is limited. Thus, the mutual interference between the respective cooperating orientation means can be further improved.
Another embodiment is characterized in that the upper boundary edge of the orientation surface with respect to the lower boundary edge is arranged upstream in the circumferential direction. Thus, an undercut can also be created on the orientation surface for cooperation with the abutment surface of the first orientation means. Thus, the orientation security can be further improved.
A further possible embodiment has the features that the orientation section has an orientation flange running through the circumference, which orientation flange is arranged or formed in the axial direction distanced from the end face, and that the at least one second orientation means is arranged or formed on the orientation flange. Thus, the circumferential clamping force of the side wall and the guarantee strip arranged thereon can be utilized for the orientation process.
A further embodiment provides that the orientation flange, starting from its outer peripheral surface, has a flange surface extending in an axial section in the direction of the longitudinal axis and inclined in the direction of the end surface. Thus, a secure support of the guarantee band can be created with the first orientation means arranged thereon.
Another embodiment is characterized in that at the orientation section, in particular its orientation flange, three second orientation means are provided, which second orientation means are arranged distributed to one another uniformly over the circumference. By providing a plurality of orientation means, the maximum necessary orientation path and the associated relative swivel angle between the orientation tool and the screw cap can thus be reduced. Thereby, a faster orientation process can be achieved, whereby the efficiency of the joining device can be improved.
Finally, a further preferred embodiment is characterized in that the flange surface in the circumferential direction, starting from the upper boundary edge of a second orientation means towards the lower boundary edge of the same second orientation means or a downstream downstream second orientation means is formed sloping. As a result, in all cases a secure mutual orientation can be achieved by the respectively cooperating first and second orientation means. Moreover, as well as unintentional damage to the first orientation means during the orientation process can be avoided.
For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

The term "in particular" is understood below to mean that it may be a possible more specific training or specification of an object or a method step, but not necessarily a compelling, preferred embodiment of the same or a compelling approach.
In Fig. 1 a possible embodiment of a container 1 is shown, which may also be referred to as a package or packaging body. The container 1 comprises in this embodiment a package body 2 with a neck 3 as part of a closure device 4. The closure device 4 comprises at least the neck 3 and a screw cap 5. From the screw cap 5, the pouring opening formed by the neck 3 is closed in its screwed-on closure position.
The package body 2 may be formed by a sealed foil packaging, which defines a receiving space not specified.
Such containers 1 can be used for example for pourable, liquid and / or free-flowing goods, especially food or food. However, other pourable or industrious goods, such as e.g. Cleaning or washing agents, oils, lubricants, solvents, paints, or the like. Be stored in the container 1 for issue. The package body 2 can be made, for example, by folding and then sealing laminated packaging material strips.
Such packing bodies 2 can be produced, for example, on fully automatic packaging machines on which a continuous tube of roll wrapping material is formed. The web from the packaging material can also be sterilized before it is folded into the package body 2 in the region of the packaging machine. Subsequently, the web is folded from the packaging material to form a longitudinally extending tube. At an open end of the tube thus produced or the packaging body 2 already separated from the tube, an unspecified terminating part can be formed with the neck 3, in particular molded into it in an injection molding process. This production of such containers 1 or packaging is well known, which will not be discussed in more detail here.
FIGS. 2 to 6 show a possible embodiment of the screw cap 5 for forming the closure device 4.
The screw cap 5 serves for the first closure of the container 1 and can also serve to reclosure of the receiving space, in particular the neck 3 and the pouring opening. The screw cap 5 comprises a cap body 6, which in turn comprises a cap wall 7 and a circumferentially formed apron-shaped side wall 8. Through the center of the disk-shaped cap wall 7 extends a longitudinal axis 9 defined by the side wall 8. The side wall 8 is basically tubular or hollow cylindrical in shape and bounded by an outer surface 10 and an inner surface 11. Furthermore, the side wall 8 projects from the cap wall 7 in the axial direction and has an open front end 12 on its side facing away from the cap wall 7.
On the inner surface 11 of the side wall 8 of the cap body 6, at least one thread 13 is arranged or formed with a thread start 14 and a threaded end 15 arranged distanced in the circumferential direction thereof. Preferably, a plurality of the threads 13 are provided so as to reduce the extent of Aufschraubwinkels and the Abschraubwinkels from the neck 3 and yet seen over the circumference sufficient tightness in the closed position of the screw cap 5 at the neck 3 and arranged there in the same number, but not to allow more closely designated threads. Under screwing is generally understood that screwing, by means of which the screw cap 5 is applied for closing the neck 3 on this. Unscrewing is understood to mean the opening movement and the subsequent removal of the screw cap 5 from the neck 3.
To indicate the unopened state of the closure device 4, the screw cap 5 may also comprise a guarantee strip 16, which is arranged in the region of the open front end 12 of the side wall 8 thereto. In most cases, the side wall 8 ends in an end face. There are a variety of configurations and embodiments of the guarantee strip 16, wherein only one possible embodiment is shown and described here. The guarantee strip 16 has in this embodiment, the shape of a circumferentially formed ring and can also be referred to as a guarantee ring. The guarantee strip 16 is usually connected by means of a plurality of predetermined separation points at least partially separable with the side wall 8, in particular the front end 12. The predetermined separation points are formed by connecting webs, wherein in the circumferential direction between the individual predetermined breaking points between the guarantee strip 16 and the side wall 8, in particular their end face,
In this embodiment, after the manufacture of the screw cap 5, the guarantee strip 16 can be folded into a securing position projecting in the direction of the longitudinal axis 9 from a production position projecting in the axial direction beyond the open front end 12. Thus, the shaping can be done in an injection molding process. In the securing position, the guarantee strip 16 has an angular orientation in the cap interior and against the cap wall 7. In this securing position also placing, in particular screwing the screw cap 5 on the neck 3 of the package body. 2
In order to be able to detect or recognize the position of the thread start 14 of the at least one thread 13 on the inner surface 11 during the process of joining the screw cap 5 to the neck 3, at least one first orientation means 17 is provided. The at least one first orientation means 17 is arranged or formed on the guarantee strip 16.
If the guarantee strip 16 is brought into the securing position or position folded inwards into the cap cavity, the at least one first orientation means 17 protrudes in the radial direction against the longitudinal axis 9 and thus in the direction of the latter. This position can be seen inter alia in Figs. 2 to 4.
If the guarantee strip 16 is still in the undeformed production position, the at least one first orientation means 17 protrudes outward in the radial direction onto the side facing away from the longitudinal axis 9 via the guarantee strip 16. This position can be seen in FIG. 6. In the lower left corner of the screw cap 5 is still the retracted securing position of the guarantee strip 16 shown in dotted lines.
The at least one first orientation means 17 may be formed as an extension 18 projecting beyond the guarantee strip 16. The extension 18 may have a first stop surface 19 formed projecting over the guarantee strip 16 in the radial direction on the longitudinal axis 9. The first stop surface 19 forms with the surface of the guarantee strip 16 a stop edge 20, from which the stop surface 19 extends in the direction of a body edge 37. Thus, the first stop surface 19 ends on the side facing away from the guarantee band 16 side with the body edge 37. Furthermore, the first stop surface 19 have a triangular shape, wherein the first stop surface 19 bounding stop edge 20 together with the body edge 37, starting from a cap interior facing the guarantee band surface of the Warranty band 16 forms the triangular shape in the direction of the cap wall 7. For the definition of the orientation of the stop edge 20, first a reference plane 21 is defined, which is spanned by the axial direction and the radial direction. The stop edge 20, in turn, when viewed in the axial direction in the cap interior on a normal plane to the longitudinal axis 9 projected longitudinal course, wherein the projected longitudinal course has a direction parallel to the reference plane 21 extending alignment. The stop edge 20 with its projected longitudinal course is seen in the same direction of view (in the axial direction in the cap interior) seen in the clockwise direction with respect to the reference plane 21 arranged to extend running.
This special orientation of the stop edge 20 is advantageous in this embodiment, since the guarantee strip 16 is folded from its manufacturing position in the direction of the longitudinal axis 9 and the cap wall 7 directed securing position. The production position of the screw cap 5 is shown in FIG. 6. In order to be able to carry out a removal movement oriented in the axial direction in the production position, the stop face 19 is to be aligned with a longitudinal course parallel thereto with respect to the axial direction. As a result of the folding over of the guarantee strip 16 with the at least one first orientation means 17 arranged thereon, this displacement or displacement of the previously described projected longitudinal course of the stop edge 20 with respect to the first reference plane 21 occurs.
If a different design of the guarantee strip 16 is used, it is possible to deviate from this staggered arrangement. Then at least the orientation of the stop edge 20 could take place in the radial direction. The same then also applies to the orientation of the second orientation means 29 described below, in particular at least one upper boundary edge 33 delimiting the orientation means 29 and / or lower boundary edge 34.
To form an undercut and rebounding or arranged abutment surface 19 starting from its body edge 37 in the direction of the stop edge 20, the stop surface 19 with the surface of the guarantee strip 16 include an acute angle of less than 90 °.
In order to form a grinding transition towards the surface of the guarantee strip 16 on the side of the extension 18 facing away from the abutment surface 19, the extension 18 can be made sloping starting from the body edge 37 in the direction of the guarantee strip 16. The cap interior facing surface of the extension 18 so can pass smoothly into the surface of the guarantee strip 16 and thus expire abrasive.
Irrespective of or in addition thereto, it would also be conceivable that the at least one first orientation means 17 can be designed as a recess 22 or depression in the guarantee strip 16. This is indicated in Fig. 4 in dashed lines. From the recess 22 or the recess, a further stop surface 23 is formed.
5, depending on the longitudinal course, the stop edge 20 and, connected thereto, at least one section of the stop face 19 or 23 and the thread start 14 of the at least one thread 13 in a common axial plane extending through the longitudinal axis 9 " A "arranged. If this is the case, extends the at least one thread 13, starting from its thread beginning 14 in the circumferential direction on the side facing away from the stop surface 19 or 23 side to its threaded end 15th
Preferably, three threads 13 and the same number of first orientation means 17 - thus also three pieces - are provided on the inner surface 11 of the side wall 8. The threads 13 and the associated orientation means 17 are each arranged in pairs and may each be uniformly distributed to each other over the circumference.
For sealing between the screw cap 5 and the neck 3 of the packing body 2 can be arranged on the cap wall 7 a circumferentially formed sealing ring 24 and connected to the cap wall 7. The sealing ring 24 is arranged distanced in the radial direction from the side wall 8 in the direction of the longitudinal axis 9 and is sealingly against the inner surface of the neck 3. A possible training in cooperation with the neck 3 describes the WO 2013/040621 A1. The neck 3 has a first portion with a first diameter and an adjoining second portion with a second diameter.
The first diameter is smaller than the second diameter. Furthermore, the second section is closer to the package body 2 than the first section. On the sealing ring 24, a sealing bead is provided, which protrudes in the radial direction from the sealing ring 24 on the side facing away from the longitudinal axis 9 side. When the screw cap 5 is closed and screwed onto the neck 3, the sealing ring 24 with its sealing bead extends beyond the first section of the neck in the direction of the packing body 2, so that the sealing bead projects at least in sections into the second section of the neck 3.
Due to the fact that the first portion of the sealing bead engages behind and overlaps, there is still no leakage of the closure device 4 even after a slight opening stroke during unscrewing.
FIGS. 7 to 9 show and describe an orientation tool 25 designed in particular as an orientation punch. The orientation tool 25 serves for the front-side receiving and placing a screw cap 5 and may comprise a cylindrically shaped base body 26, which in turn defines a longitudinal axis 27. Furthermore, an orientation section 28 can be arranged or formed at an end region of the base body 26, by means of which a mutual relative alignment of the screw cap 5 located on the orientation section 28 is made possible.
For this purpose, at least one second orientation means 29 is provided on the orientation section 28. The at least one second orientation means 29 serves for the alignment or orientation process for cooperation with at least one arranged on the guarantee strip 16 or first orientation means 17 for the screw cap 5. The orientation section 28 has a directed in a vertical direction with respect to the longitudinal axis 27 end face 30.
At the end face 30, the cap wall 7 of the cap body 6 can be supported against it and thus a pressure force on the screw cap 5 can be exerted.
If the sealing ring 24 described above is also part of the screw cap 5, it can serve for centering the screw cap 5 on the orientation section 28 in the peripheral area of its end face 30.
The at least one second orientation means 29 is here arranged or formed on an outer circumferential surface of the orientation section 28 and in the axial direction distanced from the end face 30. The spatial separation of the at least one second orientation means 29 from the end face 30 has the advantage that on the cap wall 7 a nearly to completely planar contact and support can be achieved. Preferably, the end face 30 is formed as a circular ring surface. In this case, the orientation section 28 has a depression or a recess in its frontal center region.
The at least one second orientation means 29 serves for abutment of the above-described abutment surface 19 or 23 of the first orientation means 17 on the guarantee strip 16 of the screw cap 5. For the definition of the orientation of the second orientation means 29, a further reference plane 31 is first defined on the orientation tool 25, which also in turn Spanned by the axial direction and the radial direction. The at least one second orientation means 29, for its part, has an orientation surface 32 extending in a parallel direction with respect to the reference plane 31.
For mutual orientation, the screw cap 5 placed on the orientation tool 25 is rotated relative to the common longitudinal axes 9, 27 with respect to the rotationally fixed orientation tool 25 until the at least one first orientation means 17 of the screw cap 5 abuts the at least one second orientation means 29. In this embodiment, the stop surface 19 or 23 comes at least partially to the orientation surface 32 to the plant.
However, it would also be possible to keep the screw cap 5 fixed in rotation and to rotate the orientation tool 25 about the common longitudinal axes 9, 27 until the orientation surface 32 on the stop surface 19 or 23 also comes into contact.
The orientation surface 32 is further limited in the axial direction by an upper boundary edge 33 and a lower boundary edge 34. The designation and position specification upper and lower of the two boundary edges 33, 34 refers to the proximity to the end face 30 of the orientation section 28.
The upper boundary edge 33 is located closer to the end face 30 than the lower boundary edge 34. To form an undercut at the
Orientation surface 32 may be upstream of the upper boundary edge 33 of the orientation surface 32 with respect to the lower boundary edge 34 seen in the circumferential direction. This upstream refers to a view in the axial direction of the end face 30 in a counterclockwise displacement with respect to the lower boundary edge 34th
Thus, the orientation surface 32 with an outer flange 36 includes an acute angle. The angular extent of the acute angle is preferably chosen to be the same as described above for the stop surface 19 or 23. The acute angle can in each case have a value between 60 ° and 85 °, in particular between 70 ° and 80 °, preferably of 75 °.
The above-described orientation of the orientation surface 32 with respect to the further reference plane 31 when the orientation surface 32 does not form an undercut and has an axial extent is then arranged offset with respect to the reference plane 31 when seen in the axial direction on the end surface 30 in the counterclockwise direction.
If the orientation surface 32 forms an undercut, the upper boundary edge 33 has a longitudinal profile projected onto a normal plane to the longitudinal axis 27 in a view in the axial direction, which projected longitudinal profile has an alignment running parallel to the reference plane 31. Furthermore, viewed in the counterclockwise direction, the projected longitudinal course of the upper boundary edge 33 is arranged offset with respect to the reference plane 31 so as to be offset therefrom.
Furthermore, depending on the design of the tamper-evident band 16, the orientation section 28 may have an orientation flange 35 that runs continuously over the circumference. The orientation flange 35 is arranged or formed in the axial direction at a distance from the end face 30, wherein the at least one second orientation means 29 is also arranged or formed on the orientation flange 35.
The orientation flange 35 can furthermore, starting from its outer peripheral surface, have the flange surface 36 that extends in an axial section in the direction of the longitudinal axis 27 and in the direction of the end surface 30. This is especially true if the guarantee strip 16 has an angular orientation in the axial section in the direction of the longitudinal axis 9 and the cap wall 7. Thus, the guarantee strip 16 can be supported with its surface facing the cap interior adjacent to the inclined extending flange surface 36. The outermost boundary of the orientation flange 35 may be e.g. be formed by a cylindrical surface.
The number of second orientation means 29 is preferably the same as the number of first orientation means 17. In the present embodiment, the number of second orientation means 29 is three pieces, which preferably have the same pitch angle relative to the circumference as the first orientation means 17.
Furthermore, it may be advantageous for the flange surface 36 to be designed to decrease in the circumferential direction starting from the upper boundary edge 33 of a second orientation means 29 towards the lower boundary edge 34 of the same second orientation means 29 or a further second orientation means 29 arranged downstream in the circumferential direction.
To close the neck 3 is the screw cap 5. Between the neck 3 and the screw cap 5, a threaded arrangement is provided. Screwing the screw cap 5 onto the neck 3 requires a mutual orientation step to securely engage the cooperating threads together. In the case of multi-start threads, it must be ensured that all threads of screw cap 5 and neck 3 are also in operative engagement with one another in order to prevent the screw cap 5 from being slanted on the neck 3.
In order to determine the thread beginning 14 or the thread starts 14 of the screw cap 5, the orientation means described below are provided. By means of these, in each case the relative position and position of the screw cap 5 can be determined and / or aligned in accordance with specifications or desired values of the position. If the alignment is done, an unhindered Aufsetzvorgang can be performed on the neck 3 and the screwing of the screw cap 5 by means of a unscrewing device not shown. So that an oriented alignment of the screw cap 5 can take place, the orientation tool 25 is provided, by means of which the predetermined orientation and orientation of the screw cap 5 takes place. For this purpose, the screw cap 5 can be further held on its outer periphery.
