    Field of invention
    The invention relates to a closure cap for closing a container according to the preamble of claim 1 and a container with such a closure cap according to the preamble of claim 17.
    State of the art
    Closing caps are known from the prior art in the field of plastic closure caps with a tamper-evident band, which are held captive on the container and close its pouring opening. The holding function is also important because statutory provisions are to be expected which oblige the closures of beverage bottles to be permanently connected to the beverage bottle even when they are open.
    DE 24 30 775 A1 discloses such a captive closure cap. The cap consists of a screwable upper part and a lower collar which engages behind a bead on the container mouth. The upper threaded part of the cap is connected to the lower collar via an easily tearable cylindrical tongue. This tongue extends over the entire circumference and is connected to the upper part and the lower collar via an upper and a lower row of connecting prongs. This cylindrical tongue is interrupted at one point on the circumference so that it has two ends, one of which is firmly connected to the screwable cap part and the other is firmly connected to the lower collar. The connecting prongs of the upper and lower rows tear indefinitely while the cap is being screwed on. As a result, after unscrewing, prongs on the upper and lower rows are partly torn and partly still connected to the cap part and the lower collar. When pouring liquid, the cap dangling from the container can prove to be a nuisance, since it can protrude into the flow of liquid and cause liquid to spill.
    Object of the invention
    It is therefore an object of the invention to prevent the disadvantages described above by creating a captive closure cap which is not a hindrance to any use of the container to be closed.
    description
    [0005] The object set is achieved in the case of a closure cap for closing a container by the features cited in the characterizing section of claim 1. Developments and / or advantageous design variants are the subject of the dependent claims.
    The invention is characterized by a second retaining strap with a third and a fourth end and a third and fourth edge, the third end is firmly connected to the open edge of the threaded part, the fourth end is firmly connected to the guarantee ring, the third edge is releasably connected to the open edge of the threaded part with at least one third predetermined breaking web and the fourth edge is releasably connected to the guarantee ring with at least one fourth predetermined breaking web, the first and third ends having a first opening angle of at least 110 degrees and at most 170 Degrees and preferably of at least 117 and at most 135 degrees with respect to the center point of the closure cap as the vertex and the second and fourth ends include a second opening angle of at least 110 degrees and at most 170 degrees and preferably of at least 117 and at most 135 degrees with respect to the center of the Including cap as apex sweet. The center of the closure cap lies in the plane between the open edge and the guarantee ring. By choosing the first and the third opening angle, the length of the first and the second retaining strap and their position along the guarantee ring can be precisely determined so that the following functions are fulfilled regardless of the diameter of the closure cap: The first and the second retaining strap have a length which at the same time enables the threaded part to be unscrewed from the container neck. Subsequently, the length of the retaining straps allows the threaded part to be moved translationally away from the pouring opening and to be able to be moved downward along the container neck into an open position. By providing two retaining straps, this translational movement is forcibly guided and the threaded part is forced into an open position. In the open position, the threaded part is held captive on the guarantee ring or the container neck. In the open position, the bottom of the threaded part has the same orientation as in its position screwed onto the container neck, but offset translationally to the outer wall of the container neck. In addition, the first and second retaining straps prevent the threaded part from protruding into the pouring opening 33 when filling material is poured out.
    Conveniently, the first and second ends include a third opening angle of at least 40 degrees and at most 70 degrees and preferably of at least 45 and at most 63 degrees with respect to the center of the closure cap as an apex. By choosing the third opening angle, the first retaining strap has a defined length, which enables the functions set out above together with the second retaining strap.
    Conveniently, the third and fourth ends include a fourth opening angle of at least 40 degrees and at most 70 degrees and preferably of at least 45 and at most 63 degrees with respect to the center of the closure cap as an apex. By choosing the fourth opening angle, the second retaining strap has a defined length, which enables the functions set out above together with the second retaining strap.
    Since the first, second, third and fourth opening angles have a circle center as the apex, the sum of the angles must be 360 degrees.
    In a particularly preferred embodiment of the invention, the third and fourth opening angles are the same size, whereby the first and the second retaining strap are the same length. The same length of the first and the second retaining strap enables the forced translatory movement after the threaded part has been unscrewed from the container neck. The straps allow the threaded part to move in one direction only. Accordingly, there is only one open position for the threaded part.
    It is preferred if the first and the second retaining strap are arranged symmetrically on the guarantee ring with respect to a plane of symmetry which runs through the axis of rotation of the threaded part. It is also preferred that the first, second, third and fourth ends have the same normal distances from the plane of symmetry. This means that the first and second retaining straps are arranged offset by 180 degrees on the guarantee ring. As a result, when the threaded part is unscrewed, the first and second retaining straps can slide along the container neck unimpeded and be stretched.
    In a further particularly preferred embodiment of the invention, the cross section of the first and second retaining band is constant along the length of the first and second retaining band. The retaining straps thereby have constant elastic properties along their length, whereby a defined length of the retaining straps can be determined, at which the threaded part can be held stable and wobble-free on the container in its open position. In the open position, the first and second retaining straps are pretensioned. The elastic pretensioning of the retaining straps enables the threaded part to be unscrewed several times from the container neck and screwed onto it again and to be reliably held several times in the open position. The constant cross section of the straps along their length prevents the straps from being overstretched in the open position.
    In a further preferred embodiment of the invention, a first or a second narrowing of the cross section of the first or the second retaining strap is provided at the second and the fourth end, respectively, whereby the second and the fourth end can act as a joint . The movement of the first and second retaining straps during the transfer of the threaded part from the closed position into the open position is facilitated by this joint function or defined in a direction of rotation. It is also conceivable that the first and the third end have a joint function so that the first and the second retaining strap can be moved like levers with two pivot points during the movement of the threaded part. For example, the first and third ends can be kinkably attached to the open edge.
    It is preferred if the guarantee bars are arranged at regular intervals along the open edge. The guarantee ring is therefore held in a sufficiently stable manner on the threaded part so that the closure cap can be pushed onto the container neck. The threaded part can also be unscrewed with even force thanks to the even spacing of the guarantee bars.
    The first, second, third and fourth predetermined breaking webs are expediently arranged at regular intervals along the first and second or the third and fourth edge. As a result, the closure cap is also sufficiently stable in the area of the first and second retaining straps so that it can be bounced onto the container neck. In addition, the broken predetermined breaking bars and guarantee bars indicate that the threaded part has already been twisted relative to the container neck and is no longer originally closed.
    In a further particularly preferred embodiment of the invention, the position of the guarantee ring relative to the annular projection of the container neck can be changed in the axial direction and in the circumferential direction. Because the guarantee ring can be moved upward in the axial direction, it is pulled upward when the threaded part is unscrewed, so that the first and second retaining straps can be shortened and can be better adapted to the open position. Because the guarantee ring rotates when the threaded part is turned, the first and second retaining straps experience only an axial force when the threaded part is unscrewed and are pulled upwards.
    Appropriately, a first and second recess for receiving the first and second retaining band is provided on the edge of the guarantee ring facing the retaining band. As a result, the first and second retaining straps can be formed from the guarantee ring in a space-saving manner and without additional material expenditure. For example, the first and second retaining straps can be cut out of the guarantee ring or formed during the manufacturing process of the closure cap.
    In a further preferred embodiment of the invention, the first and / or the second end of the first retaining strap and the third and / or the fourth end of the second retaining strap can be bent along predefined folding lines. As a result, the first and second retaining straps can each act like a lever with two pivot points. The kink lines also make it possible that the first and second retaining straps are not bent or kinked at random positions in the open position, but rather precisely at the kink lines. As a result, the threaded part is held particularly precisely in the open position by the two retaining straps and is guided exactly into the open position by the two retaining straps.
    It has proven to be expedient if an inwardly projecting inner cone at the bottom of the threaded part, e.g. in the form of a sealing cylinder or a sealing ring, which is designed to cooperate in a sealing manner with the inner wall of the container neck in the closed position. The closure cap can therefore act as a so-called "cone-sealer" and reliably seals the bottle neck.
    In a further preferred embodiment of the invention, the retaining band has a width between 3 mm and 7 mm and preferably a width between 4 mm and 5 mm. This dimensioning ensures that the retaining strap does not tear off unintentionally, especially if the predetermined breaking webs are torn off. In addition, the closure cap is not too high and can be joined together to form a seal with standardized container necks with external threads.
    The invention is also characterized in that the closure cap is designed to interact with a standardized container neck with an external thread and an annular projection. The closure cap can therefore be placed on standardized container necks, in particular on PET beverage bottles. Containers which are joined together with the closure cap according to the invention therefore do not have to be specially adapted to the closure cap.
    The closure cap is expediently made of a plastic material, preferably HDPE (high density polyethylene) or PP (polypropylene). The closure cap can therefore be produced with standard plastic materials, from which known closure caps with a guarantee ring are also produced.
    In a further preferred embodiment of the invention, the threaded part, the guarantee ring, the retaining strap and the at least one first and second predetermined breaking element are made in one piece. As a result, the closure cap can be produced in an injection mold without the need for further processing steps in order to form the first and second retaining straps. The inner cone is preferably also produced in one piece together with the other parts of the closure cap.
    Another aspect of the invention relates to a container comprising a container body, a container neck adjoining the container body, an external thread formed on the container neck and a closure cap according to the description above.
    In a particularly preferred embodiment of the invention, a shoulder is formed on the container neck, which is formed below the guarantee ring or is formed by the guarantee ring and the length of the first and second retaining strap is dimensioned such that the threaded part from a closed position after unscrewing can be lifted off the container neck and positioned below the shoulder in an open position, the threaded part being held in the open position on the first and second retaining straps, at least partially resting with the open edge on the container body and resting on the shoulder. The threaded part is pulled into the transition between the shoulder and the container body in the direction of the container neck with the help of the retaining straps, whereby a holder for the threaded part is created at the transition. Due to the support on the shoulder and the container body, the threaded part no longer has any freedom of movement and is therefore kept particularly stable and wobble-free in this open position.
    The shoulder is expediently a support ring which is formed at the transition from the container neck to the container body. Such a support ring is in any case present in a plastic bottle, in particular a bottle made of PET, for reasons of production technology. It is therefore particularly practical to use this support ring as a stop for the threaded part. If there is no support ring on the container, it is also possible to form a shoulder on the container neck with a length in the circumferential direction, which length enables the first cylindrical jacket of the threaded part to be supported on the shoulder. It is also conceivable that the guarantee ring is used as a shoulder on which the first cylindrical jacket can be supported.
    In a further particularly preferred embodiment of the invention, at least one first recess is provided in the radial direction on the support ring, whereby a first holding side with a first corner and a second holding side with a second corner are formed on the support ring, the first and second corner are present at the transition from the first and second holding side to the open edge of the support ring. By providing the recess, the jacket of the threaded part can rest on the support ring at two points when it is pulled by the first and second retaining straps to the support ring in the open position or is clamped on it. The jacket rests at a first point on a first corner of the first holding side with the edge of the support ring. With a second point, the jacket rests on a second corner of the second holding side with the edge of the support ring. As a result, the threaded part is held in the open position on the container in a stable and wobble-free manner. If a plurality of first depressions are provided, these can serve to guide the retaining straps or to hold them in the open position of the threaded part in a defined position. This improves the stability of the threaded part in the open position even further.
    In a further preferred embodiment of the invention, the at least one first recess is V-shaped or U-shaped. The V or U shape can be produced with little effort and ensures that the open edge of the threaded part rests in a stable manner at two points, namely the first and the second corner. The angular size of the first and second corner is particularly advantageous in the case of a V- or U-shaped recess in order to hold the threaded part reliably. The first recess can have a depth up to the approach of the support ring on the container neck.
    In a further preferred embodiment, a plurality of second depressions is provided on the support ring and these second depressions are arranged together with the first and second retaining straps symmetrically with respect to a plane of symmetry, the plane of symmetry running through the axis of rotation of the threaded part. The second depressions are preferably hook-shaped. Due to their hook-shaped design, the second recesses are particularly suitable for fixing the retaining straps when the threaded part is in the open position. The retaining straps can hook into the second recesses. Due to the symmetrical arrangement with respect to the plane of symmetry, the position of the possible open positions is clearly specified.
    In a preferred embodiment of the invention, the length of the first and second retaining straps is dimensioned such that the threaded part can be lifted from a closed position after unscrewing the container neck and can be positioned next to the container neck in an open position and in the open position on the first and second tether is held. As already stated above, the first and second retaining straps enable a joint function or a lever function due to their defined length and their defined position on the guarantee ring and the threaded part, whereby the threaded part can be translated translationally to a defined open position and in this open position to the container neck is held.
    In a further particularly preferred embodiment of the invention, the first and second retaining straps are elastically tensioned in the open position of the threaded part, whereby the threaded part is pulled against the container neck or the shoulder in the open position. As already stated above, the elastic pre-tensioning of the retaining straps holds the threaded part on the container neck or the shoulder in a stable and wobble-free manner. The elastic stretching of the retaining straps in the open position also allows the threaded part to be transferred into the open position several times and can consequently be screwed onto the container neck several times.
    The axis of rotation of the threaded part and the axis of rotation of the container neck are expediently essentially parallel in the open position of the threaded part. As a result, the threaded part is in the open position in a position in which it does not protrude beyond the container neck and also does not protrude into the pouring opening. The threaded part therefore does not interfere with the use of the container, although it is held captive on this.
    It proves to be advantageous if the length of the first and second retaining straps is dimensioned such that the axial orientation of the threaded part is essentially identical in the open position and in the closed position. After being unscrewed from the container neck, the threaded part can therefore be transferred into the open position by means of a translatory, positively guided movement.
    It proves to be advantageous if the closure cap can be pushed onto the bottle neck. The container can therefore be closed fully automatically and accordingly quickly and reliably with the closure cap after it has been filled.

    In FIGS. 1 to 10, a closure cap is shown which is designated as a whole by the reference numeral 11. The closure cap 11 is held captive on a container 13, in particular on a bottle 13. The container 13 is indicated in FIGS. 4 to 10. The closure cap 11 comprises a cylindrical threaded part 15, a guarantee ring 17 and a first and a second retaining strap 19a, 19b.
    The threaded part 15 comprises a bottom 21 and a first cylindrical jacket 23 with an open edge 25. An internal thread 27 is formed on the inside of the jacket 23. The container 13 comprises a container body 28 and a container neck 29 adjoining the container body 28. The container neck 29 is designed as a second cylindrical jacket. An external thread 31 is formed on the container neck 29, which cooperates with the internal thread 27. As a result, the threaded part 15 can be screwed onto and unscrewed from the container neck 29. The closure cap 11 closes the pouring opening 33, which is provided inside the container neck 29.
    The guarantee ring 17 is held in a form-fitting manner on the container neck 13. For this purpose, an annular projection 35 is formed on the outside of the container neck 29, which projections 37, formed on the inside of the guarantee ring 17, can engage under. The guarantee ring 17 can be rotated relative to the container neck 29.
    The first retaining strap 19a has a first end 39 and a second end 41. The first end 39 is firmly connected to the open edge 25. The second end 41 is firmly connected to the guarantee ring 17. As a result, the closure cap 11 is held captive on the container 13. Furthermore, the first retaining strap 19 has a first edge 43 and a second edge 45. The first edge 43 is connected to the open edge 25 with at least one first predetermined breaking web 47 and the second edge 45 is detachable with at least one second predetermined breaking web 49 with the guarantee ring 17 connected.
    The second retaining strap 19b has a third end 51 and a fourth end 53. The third end 51 is firmly connected to the open edge 25. The fourth end 53 is firmly connected to the guarantee ring 17. As a result, the closure cap 11 is also held captive on the container 13. Furthermore, the second retaining strap 19b has a third edge 55 and a fourth edge 57. The third edge 55 is connected to the open edge 25 with at least one third predetermined breaking web 59 and the second edge 45 is detachable with at least one fourth predetermined breaking web 61 with the guarantee ring 17 connected.
    In addition, the guarantee ring 17 is held with a plurality of guarantee webs 63 on the open edge 25. The guarantee bars are preferably arranged on the guarantee ring 17 at regular intervals. It goes without saying that the areas occupied by the first and second retaining straps 19a, 19b on the guarantee ring 17 are free of guarantee bars 63.
    It is preferred if the first and the second retaining strap 19a, 19b has a width between 4 mm and 5 mm so that it is sufficiently stable.
    Since the closure cap 11 is rotationally symmetrical, it has a center point 65. The center point 65 lies in the imaginary plane between the open edge 25 and the guarantee ring 17. The first end 39 and the third end 51 close a first opening angle 67 of at least 110 degrees and at most 170 degrees and preferably at least 117 and at most 135 degrees with respect to the center point 65 as the vertex. The second end 41 and the fourth end 53 enclose a second opening angle 69 of at least 110 degrees and at most 170 degrees and preferably of at least 117 and at most 135 degrees with respect to the center point 65 as the vertex.
    The first end 39 and second end 43 enclose a third opening angle 71 of at least 40 degrees and at most 70 degrees and preferably of at least 45 and at most 63 degrees with respect to the center of the closure cap as the apex. The third end 51 and the fourth end 53 enclose a fourth opening angle 73 of at least 40 degrees and at most 70 degrees and preferably of at least 45 and at most 63 degrees with respect to the center point 65 as the vertex. It goes without saying that the sum of the first, second, third and fourth opening angles 67, 69, 71, 73 must be 360 degrees. By choosing the first, second, third and fourth opening angle, it is possible for the first and second retaining straps 19a, 19b to have a certain length which enables the functions of the closure cap described below.
    The third and fourth opening angles 71, 73 are expediently the same size, which is synonymous with the fact that the first and second retaining straps 19a, 19b are of the same length. The first and second retaining straps 19a, 19b are preferably worked out of the guarantee ring 17 offset by 180 degrees.
    According to the embodiment of FIGS. 1 and 2, a first and a second constriction 75, 77 of the cross section of the first and the second retaining strap 19a, 19b are provided at the second and fourth ends 41, 53, respectively. The second and fourth ends 41, 53 can act as a joint through the first and second constrictions 75, 77.
    In the embodiment according to FIGS. 3 and 5 to 7, the cross section of the first and second retaining straps (19a, 19b) is constant along the length of the first and second retaining straps (19a, 19b). As a result, the first and the second retaining strap (19a, 19b) can be stretched constantly.
    A first and a second recess 79, 81 are provided on the guarantee ring 17. The first and second retaining straps 19a, 19b are received in the first and second cutouts 79, 81, respectively. This makes it possible to work the first and second retaining straps 19a, 19b directly from the guarantee ring 17, for example by cutting them out of the guarantee ring.
    If the closure cap 11 has bounced onto the container neck 29, the pouring opening 33 is closed by the closure cap 11 and the closure cap 11 is in a closed position. When the threaded part 15 is unscrewed from the container neck 29, the first, second, third and fourth predetermined breaking webs 47, 49, 59, 61 and the guarantee webs 63 break. The guarantee ring 17 rotates with the threaded part 15. During unscrewing, the first and second retaining straps 19a, 19b can straighten up. The second and fourth ends 41, 53 act as a joint through the first and second constrictions 75, 77. It is preferred if the first and third ends 39, 51 can also be bent, for example outwardly, because this simplifies the translational movement of the threaded part 15 and can take place in a more defined manner.
    By choosing the third and fourth opening angles 71, 73, the first and second retaining straps 19a, 19b have a length which enables the threaded part 15 to be moved further after it has been unscrewed from the container neck 29. When the container 13 is vertical, the threaded part 15 can first be moved linearly in the horizontal direction in the direction of the first and third ends 41, 53. When the pouring opening 33 is completely cleared by the threaded part 15, the threaded part 15 can be moved linearly along the container neck 29 parallel to the axis of rotation 83 of the container neck 29. The length of the first and second retaining straps 19a, 19b and the optional joint function of the first and third ends 41, 53 are adapted in such a way that the threaded part 15 is held on the container neck 29 in an open position (FIGS. 5 to 7). The axis of rotation 83 of the container neck and the axis of rotation 85 of the threaded part 15 are oriented essentially parallel in the open position. In the open position, the threaded part 15 is held captive on the container 13 and is fixed to the container neck 29 in such a way that it does not protrude into the pouring opening 33 when liquid is poured out of the container 13. The first and second retaining straps 19a, 19b make it possible for the threaded part 15, after it has been unscrewed from the container neck 29, to be moved into the open position in a positively guided translational movement. Due to the forced operation, there is only one open position and not several. The length and the cross section of the first and the second retaining strap 19a, 19b are preferably dimensioned in such a way that the first and the second retaining strap 19a, 19b are elastically tensioned in the open position of the threaded part 15. As a result, the threaded part 15 is pulled against the container neck 29 in the open position and is held on it without wobbling. The elastic pretensioning of the first and second retaining straps 19a, 19b also enables the threaded part to be transferred several times from the open position to the closed position and vice versa. As a result, the container neck 29 can be opened and closed several times and the threaded part 15 is held in the open position in a stable and wobble-free manner each time after opening.
    In Figures 8 to 10, a further embodiment is shown how the threaded part 15 can be arranged on the container body 28 in the open position. A shoulder 91 is formed on the container neck 29, which is formed below the guarantee ring 17 or is formed by the guarantee ring 17 itself. The shoulder is preferably formed by a support ring 91 which is located at the transition from the container neck 29 to the container body 28. The threaded part 15 is held in the open position on the first and second retaining straps 19a, 19b. In FIGS. 8 to 10, the container body 28 is shown with a container shoulder 93. The container shoulder 93 represents the transition from the container neck 29 to the cylindrical part of the container body 28. The retaining straps 19a, 19b are dimensioned such that the open edge 25 can be pulled into the open position via the support ring 91. In the open position, the threaded part 15 rests with the open edge 25 on the surface of the container shoulder 93. The first cylindrical jacket 23 rests on the support ring 91. The retaining straps 19a, 19b are preferably slightly tensioned in the open position. As a result, the threaded part 15 is pulled onto the support ring 91 and is clamped below the support ring 91. The support ring 91 prevents the threaded part 15 from tilting upwards as a result of the tension of the retaining straps 19a, 19b. Rather, the support ring 91 has the effect that the open edge 25 is pressed against the container shoulder 93. As a result, the threaded part 15 is kept particularly stable in the open position according to FIGS. 8 to 10. It is also conceivable that the first cylindrical jacket 23 rests against the guarantee ring 17 if there is no support ring. In this case, the guarantee ring 17 acts as a shoulder for the threaded part 15.
    As FIG. 8 shows, the axis of rotation of the container neck 83 and the axis of rotation 85 of the threaded part, established by the container shoulder 93, enclose an acute angle. The larger the angle, which can be at most 90 degrees; is between the two axes of rotation 83.85, the greater the tensile force on the container shoulder 93. The smaller the angle between the two axes of rotation 83.85, the greater the tensile force on the support ring 91.
    In FIGS. 11 and 12, the support ring 91 is shown with a plurality of first depressions 95 which are arranged next to one another. The first recess 95 is preferably V-shaped or U-shaped. As a result, a first and a second holding side 97, 99 are present at the edges of the recess. A first corner 101 is formed at the transition from the first holding side 97 to the open edge 105 of the support ring 91. A second corner 103 is formed at the transition from the second holding side 99 to the open edge 105 of the support ring 91.
    The recess 95 makes it possible that in the embodiment shown in FIGS. 8 to 10, the threaded part 15 is held in a particularly stable manner on the support ring 91. The jacket 23 of the threaded part 15 not only rests with one point on the support ring 91 (see FIG. 8), but is pulled with the retaining straps 19a, 19b to one point each on the first and second retaining side 97,99. These points are formed by the first and second corners 101, 103. This “2-point support” additionally stabilizes the threaded part 15 in the open position. In addition, the first recesses 95 can be used so that the first and second retaining straps 19a, 19b are received therein when the threaded part 15 is in the open position. As a result, the retaining straps 19a, 19b are held or guided. The first depressions 95 contribute to the fact that the retaining straps 19a, 19b are in an unambiguous position in the open position and cannot slip. This leads to the threaded part 15 being held in its open position in an even more stable manner.
    The first depressions 95 can be formed all around at the same intervals on the support ring 91. As FIG. 12 shows, the first depressions 95 can also be provided in two symmetrically arranged partial regions which are separated from one another by two separating webs 107. As a result, a first and a second area are specified in which the threaded part 15 can assume its open position.
    In FIGS. 13 and 14, an embodiment is shown in which second depressions 109 are provided on the support ring 91. The second recesses are preferably hook-shaped, so that the first and second retaining straps 19a, 19b can hook into the second recesses 109. The hook-shaped depressions 109 enable an improved guidance of the retaining straps 19a, 19b on the support ring 91. The second depressions 109 can be arranged in two partial areas on the support ring 91. As already described further above, the two partial areas can be separated from one another by separating webs 107 in order to predetermine two unambiguous areas for the open position of the threaded part 15. The second depressions 109 can be arranged symmetrically with respect to a plane of symmetry 111. The first and second retaining straps 19a, 19b are also expediently arranged symmetrically with respect to the plane of symmetry 111. The plane of symmetry 11 runs through the axis of rotation 85 of the threaded part 15. Recesses 113, which serve to reduce weight, can also be provided on the support ring 91.
    No first depressions 95 are shown in FIGS. 13 and 14 and the first cylindrical jacket 23 rests on the open edge 105 as a result. The provision of first recesses 95 for more stable holding of the threaded part 15 in the open position in addition to the second recesses 109 is of course possible.
    At the bottom 21 of the threaded part 15 there is preferably an inwardly projecting inner cone 87 (Figure 6), e.g. in the form of a sealing cylinder or a sealing ring. The inner cone 87 is designed to cooperate in a sealing manner with the inner wall 89 of the container neck 29 in the closed position. The closure cap 11 can therefore act as a so-called “cone sealer” and reliably seals the container neck 29.
    The closure cap 11 is made of a plastic. Preferred plastics include PP and HDPE.
