CAP

Description

Field of invention

[0001] The invention relates to a closure cap according to the preamble of claim 1 and a container according to the preamble of claim 18. State of the art

[0002] Current technology in the field of plastic closure caps with a tamper-evident band includes caps that are permanently attached to the container and seal its pouring opening. This retention function is also of great importance because legal regulations will be enacted in the coming years requiring that closures of beverage bottles remain permanently attached to the bottle even when open.

[0003] Caps are also known that feature two retaining bands connecting a threaded portion of the cap to a tamper-evident ring. These two bands can act as a hinge, allowing the threaded portion to be folded away from the tamper-evident ring (or the container being sealed) from a closed to an open position. A locking lug is formed on the open edge of the threaded portion. This lug allows the threaded portion to be locked onto the external thread of the bottle neck in the open position. This secures the threaded portion in the open position and prevents it from interfering with the pouring process. However, the locking lug inevitably protrudes into the tamper-evident ring, necessitating a recess in the ring to accommodate the lug. This recess inevitably weakens the tamper-evident ring.The cutout makes the guarantor ring less dimensionally stable and increases the risk of it being pulled off the bottle neck when the threaded part is unscrewed. This compromises the reliability of the guarantor function and the retention of the cap, especially with guarantor rings of larger diameters.

[0004] WO 2020 / 227813 A1 describes a closure for a container which has two retaining straps that separately connect a closure cap to a tamper-evident ring. Each of the two retaining straps is connected to the closure cap by a hinge. Object of the invention

[0005] The disadvantages of the described state of the art result in the task of creating an improved captive closure cap in which the removal of the guarantor ring when unscrewing the threaded part is reliably prevented. Description

[0006] The problem is solved in a cap for closing the pouring opening of a container by the features listed in the characterizing section of claim 1. Further developments and / or advantageous embodiments are the subject of the dependent claims.

[0007] The invention is preferably characterized in that the bridge section has a greater thickness than the rest of the guarantor ring, that a first and second locking lug project from the open edge adjacent to the first and third ends, respectively, and that a gap is formed between the first and second locking lugs, and that a retaining ridge is formed on the bridge section which projects into the gap in the closed position. These features ensure that the guarantor ring has sufficient stability to prevent it from being unintentionally deformed when unscrewed and thus pulled off the spout. The retaining ridge centers the guarantor ring on the spout and thus also prevents the guarantor ring from being pulled off the spout.

[0008] In the open position, the threaded part can be locked onto the external thread of the spout using the two locking tabs. This doubles the threaded part's position in the open position, ensuring a stable connection to the spout, preventing it from twisting unintentionally relative to the spout and thus preventing any interference with the pouring process.

[0009] It has proven advantageous to have a radially outward-projecting first or second step at the open end of the first or second retaining lug, respectively. These steps improve the locking mechanism on the external thread by increasing the engagement area.

[0010] Advantageously, a first and second recess are provided on the bridge section, into which the first and second locking lugs protrude in the closed position, and between which the retaining bar rises. By providing these recesses, the guarantor ring is reduced in height, which saves material and allows the cap to fit a standard spout.

[0011] The invention is also preferably characterized in that the first and third ends are hinged to the open edge by a first and second hinge. The hinges allow the threaded part to pivot around the hinges into the open position relative to the first and second retaining bands, making the process of moving the threaded part into the open position simple and self-explanatory for the user. This also prevents the threaded part from accidentally tearing off the guarantor ring.

[0012] Advantageously, the first edge is detachably connected to the open edge of the threaded part by at least one first predetermined breaking point, and the second edge is detachably connected to the tamper-evident ring by at least one second predetermined breaking point. The third edge can also preferably be detachably connected to the open edge of the threaded part by at least one third predetermined breaking point, and the fourth edge can be detachably connected to the tamper-evident ring by at least one fourth predetermined breaking point. This provides the retaining bands with good axial support, which is necessary so that the cap can be forced onto the spout without the retaining bands being compressed or damaged.

[0013] Preferably, the first and third ends are connected to the guarantor ring by a second and a fourth predetermined breaking point, respectively. It is also preferred that the retaining bar is detachably connected to the open edge by a fifth predetermined breaking point. The provision of the two fourth and the fifth predetermined breaking points provides sufficient support and retention for the retaining straps and the retaining bar to prevent damage upon impact with the spout. Therefore, further third and fourth predetermined breaking points are unnecessary, thus saving plastic material.

[0014] In a particularly preferred embodiment of the invention, the thickness of the web section is 1.5 to 2 times that of the rest of the guarantor ring. This thickness dimension ensures that the web section has sufficient stability so that the guarantor ring is not pulled off the spout when the threaded part is unscrewed, even if the guarantor ring has a large diameter of up to 40 mm.

[0015] The transition from the bridge section to the rest of the warranty ring is advantageously designed to be gradual. This reliably prevents weakening of the warranty ring and avoids the risk of injury to users.

[0016] It is advantageous if the first and second lugs have a height between 4 and 10 mm, and preferably between 5 and 7 mm. This allows the threaded part to be securely and precisely locked onto the external thread in the open position using the lugs, without the lugs bending or being too short for proper locking.

[0017] Advantageously, the first and second steps have a height between 1 and 3 mm, and preferably between 1.5 and 2.5 mm. These steps improve the locking of the threaded part onto the external thread. Additionally, at this height, the steps pose no risk of injury, as they only protrude slightly above the threaded part in the locked position.

[0018] It is also advantageous if the first and third ends enclose a first opening angle of at least 25 degrees and at most 50 degrees, and preferably at least 35 degrees and at most 45 degrees, with respect to the center of the closure cap as its apex, and if the second and fourth ends enclose a second opening angle of at least 180 degrees and at most 220 degrees, and preferably at least 190 degrees and at most 210 degrees, with respect to the center of the closure cap as its apex. By choosing these angular values, the first and second retaining bands on the guarantor ring are in a position in which, when the threaded part is in the open position, they extend substantially tangentially along the spout. This allows the retaining bands to move with the threaded part without catching on the spout when the threaded part is moved into the open position.

[0019] Advantageously, the opening angle enclosed by the bridge section with its center point as the apex should essentially correspond to the first opening angle. The bridge section is preferably formed by cutting out the first and second retaining bands from the guarantor ring. It would also be conceivable to provide a larger distance between the first end of the first retaining band and the bridge section, or between the third end of the second retaining band and the bridge section, than if the distance were formed by cutting out the retaining bands.

[0020] Preferably, the first and second ends enclose a third opening angle of at least 40 degrees and at most 70 degrees, and preferably at least 50 degrees and at most 60 degrees, with respect to the center of the closure cap as the vertex.

[0021] It is also preferred if the third and fourth ends enclose a fourth opening angle of at least 40 degrees and at most 70 degrees, and preferably at least 50 degrees and at most 60 degrees, with respect to the center point of the closure cap as the apex. This choice of the third and fourth opening angles ensures that the first and second retaining bands have a length that allows for unscrewing, moving the threaded part into the open position, and holding the threaded part in the open position. In combination with the first and second opening angles, the retaining bands are positioned appropriately on the guarantor ring to allow the protruding movements of the threaded part.

[0022] Advantageously, the third and fourth opening angles are the same, resulting in the first and second retaining straps being of equal length. This ensures that the threaded part is held in the open position with even tension.

[0023] Since the first, second, third and fourth opening angles have a circle center as their vertex, their angle sum must be 360 ​​degrees.

[0024] In a preferred embodiment of the invention, the lengths of the first and second retaining straps are dimensioned such that they are taut in the open position and the threaded part is held in the open position. Preferably, the retaining straps are elastically tensioned, allowing the threaded part to move multiple times between the closed and open positions. The tension of the retaining straps ensures that the threaded part is held securely and without wobble in the open position.

[0025] Advantageously, a first and second recess are provided on the edge of the guarantor ring facing the first and second retaining bands to accommodate them. This allows the first and second retaining bands to be formed from the guarantor ring in a space-saving manner and without additional material. For example, the first and second retaining bands can be cut out of the guarantor ring or formed during the manufacturing process of the closure cap.

[0026] It has proven advantageous to have an inwardly projecting internal cone, e.g., in the form of a sealing cylinder or a sealing ring, molded onto the base of the threaded part. This cone is designed to seal against the inner wall of the spout in the closed position. The cap can therefore act as a so-called "cone sealer" and reliably seals the spout.

[0027] In a further preferred embodiment of the invention, the first and second retaining bands have a width between 3 mm and 7 mm, and preferably a width between 4 mm and 5 mm. This dimension prevents the retaining band from breaking unintentionally, particularly if the predetermined breaking points are torn off. Furthermore, the closure cap is not too tall and can be sealed with standardized container necks with external threads.

[0028] The invention is also characterized in that the cap is designed to interact with a standardized spout with an external thread and annular projection. The cap can therefore be fitted onto standardized container necks, particularly those of PET beverage bottles. Containers assembled with the cap according to the invention therefore do not need to be specially adapted to the cap.

[0029] The cap is preferably made of a plastic material, ideally HDPE (high-density polyethylene) or PP (polypropylene). Therefore, the cap can be manufactured using standard plastic materials, the same materials used for conventional caps with a tamper-evident ring.

[0030] In a further preferred embodiment of the invention, the threaded part, the guarantor ring, the retaining band, and the at least one first and second predetermined breaking element are manufactured in one piece. This allows the closure cap to be produced in an injection mold without the need for further machining steps to form the first and second retaining band. Preferably, the inner cone is also manufactured in one piece together with the other parts of the closure cap.

[0031] In a particularly preferred embodiment of the invention, the warranty ring has slots distributed around its circumference, each with an upper edge and a lower edge. The upper edge is formed by a circular arc-shaped section of the warranty ring, and the lower edge is formed by a wall section inclined radially inwards. The lower edge of each slot forms the projections, thereby creating engagement means for a positive-locking engagement with the annular projection. Since the engagement means, in the form of the inwardly inclined wall sections, are not present on the entire circumference of the warranty ring, and since the slots are also present, the shape of which further reduces material usage, the plastic material requirement can be significantly reduced by up to 5%.Furthermore, the inward wall section is immovable in the radial direction, thus holding the tamper-evident ring against the annular projection. It can only be pulled over this projection when the tamper-evident ring is stretched along its circumference. The wall sections hold the tamper-evident ring against the annular projection in such a way that the predetermined breaking points reliably tear before the wall sections' retention is overcome. However, the wall sections are flexible and movable in the radial outward direction. This allows the wall sections to be demolded from the injection mold with minimal effort. For the same reason, the application force required to snap the cap on is significantly reduced compared to prior art. Stretching of the tamper-evident ring, which could lead to permanent damage to the cap, is largely prevented during demolding and snapping.

[0032] Another aspect of the invention relates to a container comprising a container body, a spout adjoining the container body, an external thread formed on the spout and a cap according to the description above.

[0033] In a preferred embodiment of the invention, the first and second locking lugs engage with the external thread in the open position. As described above, this holds the threaded portion securely in the open position, preventing the cap from rotating around the spout in the open position.

[0034] In a first embodiment, the container body and the spout are made in one piece from a plastic, which allows the closure cap to be used with a commercially available plastic bottle, for example a PET bottle with a support ring.

[0035] In a second embodiment, the container is a composite beverage carton, wherein the container body is a plastic-laminated cardboard and the spout, made of plastic, is permanently connected to the container body. This makes the cap suitable for use with composite beverage cartons.

[0036] Further advantages and features will become apparent from the following description of an embodiment of the invention with reference to the schematic diagrams. These are shown in a representation not to scale: Figure 1: A perspective view of a cap from a top oblique angle in the closed position; Figure 2: A side view of the cap; Figure 3: A detailed side view of the cap; Figure 4: A side view of the tamper-evident ring, fitted onto a container spout; Figure 5: A perspective view of the cap from a bottom oblique angle; Figure 6: Another perspective view of the cap from a bottom oblique angle; Figure 7: A bottom view of the cap; Figure 8: A perspective view of the cap in the open position; Figure 9: A detailed view of the tamper-evident ring in a further embodiment; and Figure 10: A sectional view of the tamper-evident ring. Figure 9 with visualized tilt angles.

[0037] In the Figures 1 to 8A cap is shown, which is designated in its entirety by the reference numeral 11. The cap 11 is captive and attached to a container 13, for example, a beverage carton or a PET bottle. The container 13 is in the Figures 4 The closure cap 11 comprises a cylindrical threaded part 15, a tamper-evident ring 17, and a first and a second retaining band 19a, 19b. The first and second retaining bands 19a, 19b are circular and formed from the tamper-evident ring 17.

[0038] The threaded part 15 comprises a base 21 and a first cylindrical shell 23 with an open rim 25. An internal thread 27 is formed on the inside of the shell 23. The container 13 comprises a container body 28 and a spout 29 adjoining the container body 28. The spout 29 is designed as a second cylindrical shell. An external thread 31 is formed on the spout 29, which engages with the internal thread 27. This allows the threaded part 15 to be screwed onto and off the spout 29. The cap 11 closes the spout opening 33, which is provided within and limited by the spout 29.

[0039] The guarantee ring 17 is positively engaged with the spout 13. For this purpose, an annular projection 35 is formed on the outside of the spout 29, which can be engaged by projections 37 formed on the inside of the guarantee ring 17 ( Figures 9 and 10 The guarantee ring 17 is rotatable relative to the spout 29.

[0040] The first retaining band 19a has a first end 39 and a second end 41. The first end 39 is permanently connected to the open rim 25. The second end 41 is permanently connected to the tamper-evident ring 17. This ensures that the cap 11 is securely attached to the container 13. Furthermore, the first retaining band 19a has a first rim 43 and a second rim 45. The first rim 43 is connected to the open rim 25 by at least one first breakaway tab 47, and the second rim 45 is detachably connected to the tamper-evident ring 17 by at least one second breakaway tab 49.

[0041] The second retaining band 19b has a third end 51 and a fourth end 53. The third end 51 is permanently connected to the open rim 25. The fourth end 53 is permanently connected to the tamper-evident ring 17. This additionally secures the cap 11 to the container 13. Furthermore, the second retaining band 19b has a third rim 55 and a fourth rim 57. The third rim 55 is connected to the open rim 25 by at least one third breakaway tab 59, and the fourth rim 57 is detachably connected to the tamper-evident ring 17 by at least one fourth breakaway tab 61.

[0042] Additionally, the guarantee ring 17 is held at the open edge 25 by a plurality of guarantee lugs 63. The guarantee lugs are preferably arranged at regular intervals on the guarantee ring 17. It is understood that the areas occupied by the first and second retaining bands 19a, 19b on the guarantee ring 17 are free of guarantee lugs 63.

[0043] It is preferred that the first and second retaining straps 19a,19b have a width between 4 mm and 5 mm to ensure sufficient stability.

[0044] The threaded part 15 is located according to the Figures 1 or 2 in a closed position in which it is bounced or screwed onto the spout 29. When unscrewing it from the spout 29, the first and second retaining bands 19a, 19b are pulled upwards in an axial direction and are also elastically stretchable if necessary, so that the threaded part 15 can be unscrewed from the spout 29 and folded away.

[0045] The guarantee ring 17 has a first and a second recess 65, 67. The first and second retaining bands 19a, 19b are accommodated in the first and second recesses 65 and 67, respectively. This makes it possible to machine the first and second retaining bands 19a, 19b directly out of the guarantee ring 17, for example by cutting them out of the guarantee ring.

[0046] Between the first end 39 of the first retaining band 19a and the third end 51 of the second retaining band 19b, a circular arc-shaped web section 69 is formed, which preferably has the height of the guarantee ring 17. Figure 5 It is evident that the bridge section 69 has a greater thickness than the rest of the guarantee ring 17. The thickness of the bridge section 69 is preferably 1.5 to 2 times that of the rest of the guarantee ring 17. The transition from the bridge section to the rest of the guarantee ring is gradual.

[0047] At the open edge 25, a first or second locking lug 71a, 71b projects adjacent to the first or third end 39, 51. A gap 72 is necessarily present between the spaced locking lugs 71a, 71b. This is best illustrated in the Figure 8 visible.

[0048] A retaining rib 73 is formed on the bridge section 69, which projects into the space 72 in the closed position. The reinforced bridge section 69 provides the guarantor ring 17 with sufficient stability so that it cannot be deformed when the threaded part 15 is unscrewed. This reliably prevents the guarantor ring 17 from being pulled off. In addition, the retaining rib 73 centers the guarantor ring 17 on the spout by bearing against the annular projection 35 ( Figure 4This feature further prevents the tamper ring 17 from being pulled off. Furthermore, the centering ensures that all tamper-evident or shear tabs break cleanly, thus reliably indicating when the threaded part 15 has been opened. The cap 11 can have a diameter of 20 mm to 40 mm, and preferably 25 mm to 35 mm. The reinforced tab section 69 and the retaining tab 73 prevent the tamper ring 17 from being unintentionally pulled off, especially when the threaded part 15 is unscrewed for the first time, even if the cap has a large diameter of up to 40 mm.

[0049] At the open end of the first and second retaining lugs 71a and 71b, respectively, a radially outwardly projecting first and second step 75a and 75b is present. The first and second lugs 71a and 71b have a height between 4 and 10 mm, preferably between 5 and 7 mm. The first and second steps 75a and 75b have a height between 1 and 3 mm, preferably between 1.5 and 2.5 mm. The height of the steps is kept as low as possible so that they do not protrude and pose a risk of injury to the user. The steps enable the first and second locking lugs to engage securely with the external thread 31 in the open position and hold the threaded part 15 in the open position without wobble. Additionally, the height of the locking lugs and the length of the first and second retaining bands are dimensioned such that the threaded part is held securely in the open position and does not interfere when pouring contents from the container.

[0050] The bridge section 69 has a first and second recess 77a, 77b into which the first and second locking lugs 71a, 71b project in the closed position, and between which the retaining rib 73 rises. This allows the locking lugs to have the necessary height to generate sufficient stability in the open position. At the same time, the recesses are shallow enough that the bridge section 69 is not weakened.

[0051] The first and third ends 39, 51 are hinged to the open edge 25 by a first and second hinge 79a, 79b. The hinges allow the threaded part 15 to be moved precisely yet smoothly into the open position by pivoting it relative to the first and second retaining bands 19a, 19b.

[0052] The first and third ends 39, 51 are connected to the guarantor ring 17 by a second and a fourth predetermined breaking point 49, 61, respectively. Additionally, the retaining bar 73 is detachably connected to the open edge 25 by a fifth predetermined breaking point 81. This provides stable support in the axial direction in the area of ​​the bar section 69. The closure cap 11 can therefore be pressed onto the spout 29 without damaging any part of the closure cap 11. Further first, second, third, and fourth predetermined breaking points can be provided on the retaining bands 19a, 19b to increase stability.

[0053] Since the closure cap 11 is rotationally symmetrical, it has a center point 83. The center point 83 lies in the imaginary plane between the open rim 25 and the tamper-evident ring 17. The first end 39 and the third end 51 enclose a first opening angle 85 of at least 25 degrees and at most 50 degrees, and preferably at least 35 degrees and at most 45 degrees, with respect to the center point 83 as its apex. The second end 41 and the fourth end 53 enclose a second opening angle 87 of at least 180 degrees and at most 220 degrees, and preferably at least 190 degrees and at most 210 degrees, with respect to the center point 83 as its apex.

[0054] The first end 39 and the second end 41 enclose a third opening angle 89 of at least 40 degrees and at most 70 degrees, and preferably at least 50 degrees and at most 60 degrees, with respect to the center of the closure cap as its vertex. The third end 51 and the fourth end 53 enclose a fourth opening angle 91 of at least 40 degrees and at most 70 degrees, and preferably at least 50 degrees and at most 60 degrees, with respect to the center 83 as its vertex. It is understood that the sum of the first, second, third, and fourth opening angles 85, 87, 89, 91 must be 360 ​​degrees, since the first, second, third, and fourth opening angles have the center of the circle 83 as their vertex.By selecting the first, second, third and fourth opening angle, it is possible for the first and second retaining bands 19a,19b to have a specific length, which enables the functions of the closure cap 11 described above in combination with the locking lugs.

[0055] Advantageously, the third and fourth opening angles 89, 91 are of equal size, which is equivalent to the first and second retaining bands 19a, 19b being of equal length. The first and second retaining bands 19a, 19b are preferably machined from the guarantor ring 17. The sealing cap 11 can therefore act as a so-called "cone sealer" and reliably seals the spout 29.

[0056] The closure cap 11 is made of plastic. PP and HDPE are among the preferred plastics.

[0057] A sealing cone 93 is formed on the bottom 21 of the threaded part 25 in a known manner, which in the closed position seals against the spout 29 (Figure 5).

[0058] Once the cap 11 is pressed onto the spout 29, the spout opening 33 is closed by the cap 11 and the cap 11 is in the closed position. When the threaded part 15 is unscrewed from the spout 29, the first, second, third, and fourth predetermined breaking points 47, 49, 59, 61 and the guarantee bars 63 break. The centering and increased stability of the guarantee ring 17 by the bar section 69 and the retaining bar 73 ensure that all bars break cleanly and reliably prevent the guarantee ring from being pulled off the spout when unscrewing.

[0059] After unscrewing, the threaded part 15 can be pivoted into the open position around the hinges 79a and 79b. The retaining lugs 71a and 71b are in a position where it is self-explanatory that they must be engaged with the external thread 31. In the open position, the threaded part is permanently attached to the spout 29 and does not obstruct the pouring process. The locking mechanism secures the tamper-evident ring 17 to the spout in the direction of rotation, preventing it from turning. This prevents the cap 11 from twisting into the flow of liquid during pouring.

[0060] When the pouring opening 33 is resealed, the two locking lugs 71a, 71b do not rub against the external thread 31, but merely graze the inner surface of the thread because they are not positioned centrally between the retaining bands 19a, 19b. This facilitates the return of the threaded part from the open position to the closed position. This grazing action is due to the large gap 72 between the two locking lugs. If, instead of the gap 72, a locking lug were formed centrally between the retaining bands 19a, 19b on the threaded part 15, this would cause friction.

[0061] The projections 37 can be described according to the following figure description of the Figures 9 and 10The guarantee ring 17 is formed by slots 97 distributed around its circumference. Each slot 97 has an upper edge 99 and a lower edge 101. The upper edge 99 is formed by a circular arc section of the guarantee ring 17. The lower edge 101 corresponds to the free edge of an inwardly inclined, radially inclined wall section 103. Due to the inward inclination of the wall section 103, the lower edge 101 has a smaller radius than the guarantee ring 17 and can therefore abut a support (annular projection 35) of the spout 29 when the threaded part 15 is unscrewed from the spout 29. The support is formed by the annular projection 35, which is located below the external thread 31 on the spout 29.When the threaded part 15 is unscrewed, the lower edge 99 engages the projection 35 in a form-fitting manner, ensuring that the guarantee ring 17 is reliably held on the annular projection 35 even under high axial forces.

[0062] Each wall section 101 has a first subsection 105 and two second subsections 107. The first subsection 105 represents an inwardly folded shell section and is preferably flat. The second subsections 107 adjoin the inwardly facing sides of the first subsection 105 and connect it to the guarantor ring 17. The second subsections 107 can be curved or flat and are inclined inwards towards each other. The lower edge 101 of the slot 97 corresponds to the free edges of the first subsection 105 and the second subsections 107 and lies in a plane 109, which is Figure 10The plane 109 is preferably oriented perpendicular to the axis of rotation 110 of the spout 29. These described design features of the wall section 103 have the advantage that the entire lower edge 101 of the wall section 103 can rest against the annular projection 35 and does not yield under an upward axial tensile force, acting like a barb. This ensures that the guarantor ring 17 is permanently held against the projection 35 or can only be removed from the projection 35 by destroying it. The provision of the second sections 107 prevents inward movement of the first section 105 in a radial direction. However, outward movement of the first section 105 in a radial direction is possible. This movement is flexible, and the wall section 103 returns to its inwardly inclined initial position after being pushed radially outward.This has the further advantage that the guarantor ring 17 can be easily demolded and, with minimal force, bounced onto the spout 29 together with the threaded part 15. The demolding from an injection mold and the bouncing onto the spout 29 can be achieved through the flexibility of the wall section 103 without any risk of damaging it.

[0063] It is preferred that the inclined wall sections 103 have a reduced wall thickness compared to the rest of the guarantee ring 17. In the Figure 10 It has been shown that the area of ​​the lower edge 101 has the smallest wall thickness. This further improves the radial outward flexibility of the wall section 103 described above. The wall thickness of the wall section 103 increases linearly downwards from the lower edge 101.

[0064] In the Figures 9 and 10 The guarantee ring 17 is shown without the threaded part 15. In the Figures 9 and 10It is clearly visible that above the slots 97 on the guarantee ring 17 a ring ridge 111 is formed, on which the upper edges 99 lie.

[0065] In the Figure 10 A first and second inclination angle 113, 115 are shown. The first inclination angle 113 indicates the inclination of the first section 105 relative to the plane of the lower edge 101. The first inclination angle 113 has a magnitude between 60 and 80 degrees, and preferably between 65 and 75 degrees. The larger the first inclination angle 113, the better the stability of the wall sections 103 against vertical forces or axial tensile forces caused by unscrewing the threaded part 15. However, the first inclination angle 113 must not be too large, otherwise the annular projection 35 cannot be sufficiently engaged.

[0066] The second angle of inclination 115 specifies the inclination of the slot 97 relative to the plane of the lower edge 111. The connecting line 117, which represents the inclination of the slot 97, is a line connecting the upper edge 99 with the lower edge 101 in a plane spanned by the axis of rotation 110 and the connecting line 117. The second angle of inclination 115 is enclosed by the connecting line 117 and the plane 109.
