Description

The invention relates to a tamper-evident closure for containers such as canisters, bottles or the like. Made of plastic, glass, etc., in particular reusable bottles, the neck of which is provided with a screw thread and a transfer ring (ring-shaped projection) arranged below the screw thread. Tamper-evident closures have the purpose of indicating that the container has been opened, i.e. the integrity of the entire tamper-evident seal guarantees the consumer the original contents of the container (see e.g. US-A-4 458 822).

It is a tamper-evident closure for containers, with a screw cap provided with an internal thread and with a sealant, optionally provided for sealing the container mouth, optionally with a screw cap, with a safety ring adjoining the screw cap at the bottom, firmly connected and designed to be tearable, and with at least one tab which adjoins the safety ring downwards via a film hinge connection and can be swiveled inwards for engaging under a transfer ring of the container neck arranged below the counter-thread (position of use). There is the possibility that the safety ring can be divided into several sections (safety ring sections) by the arrangement of a plurality of non-tearable first bridges designed as connecting points and tearable second bridges designed as predetermined breaking points. When the tamper-evident closure is opened for the first time, according to a preferred embodiment, the security ring or the respective security ring section is deformed in connection with the respective tab assigned to it in such a way that it bulges outwards and the radius is reduced. The tab bends in the circumferential direction of the tamper-evident closure in the direction of the security ring or security ring section, as a result of which this and the tab stiffen as much as if the tab had not subsequently been swiveled inwards (use position), but instead was produced together with the security ring in this position. As a result, the tab in the circumferential direction of the tamper-evident closure does not grip under the transfer ring of the container neck as a whole and it is ensured that it does not hook under the transfer ring of the container neck as a whole and thus cannot be folded down again into the manufacturing position during the screwing process. This previously described deformation and stiffening is ensured by the second bridge (s) of the safety ring, which opposes / oppose the safety ring or safety ring section and the tab before they are torn open to such a great extent that this deformation and stiffening are made possible. However, if, for example, the tamper-evident closure with the safety ring torn open is screwed back onto the container neck and unscrewed from it, the tab slides due to the lack of deformation due to the tear and stiffening, difficult to pass the outer contour (transfer ring and external thread) of the container neck and it can happen that it is folded down again into the production position. According to the invention, it is proposed that the lower section of the tab have an overrun means which extends over part of the circumference of the tab. By "circumference of the tab" is meant that area of the circumference of the tamper-evident closure over which the tab extends. The ramp means that the tab, when the safety ring is torn open, is not pressed under the transfer ring when the tamper-evident closure is subsequently opened, but instead glides smoothly past the entire outer contour of the container neck.

In addition, the security against manipulation of the tamper-evident closure according to the innovation is not impaired by the casserole, which is of very particular importance. The previously described deformation and stiffening of the safety ring or safety ring section in connection with the bracket can be favored by a bracket with high longitudinal rigidity with a correspondingly low transverse rigidity. It is therefore to be regarded as advantageous if the relationship between the longitudinal and transverse stiffness as a result of the subdivision of the tab into appropriately shaped and arranged tab sections, in particular in the longitudinal section when viewed in the production position, shows a lower pool section spreading from top to bottom and outwards to an upper pool section and the arrangement of corresponding reinforcing ribs running in the circumferential direction of the tamper-evident closure on these tab sections is achieved.

The tamper-evident closure according to the innovation fulfills all the requirements that must be placed on such a closure, both in terms of its aesthetics, ease of use and security against manipulation, as well as in terms of its suitability for use with conventional closing heads due to the fact that it can also be used at maximum speeds when capping (mechanical closure) ) easy sliding over the neck of the container and in particular it can be produced inexpensively as a mass-produced item by means of an extremely simply constructed and therefore inexpensive and trouble-free working injection molding tool.

The tamper-evident seal according to the invention is shown graphically on the basis of the diagrams shown below.

At least one tab 5 is preferably supported in the inwardly pivoted position (use position) above at least one film hinge connection 4 with a not insignificant area of its height via at least one contact device against the safety ring 3. The position of the tamper-evident closure 1, in which the tabs 5 are turned in relatively, is referred to as the “use position”. Preferably, as seen in longitudinal section in the production position, at least one contact device has at least one transition area of the safety ring 3 and / or at least one that tapers at least essentially gradually and tapers in the direction of the pivot line of at least one film hinge connection 4 and extends at least over the partial circumference of at least one tab 5 Tab 5 on.

The embodiments according to FIGS. 3, 6, 7, 9 and 12 to 18, seen in the production position in longitudinal section, each have a transition area for each security ring 3 and tab 5, the position of which determines the respective film hinge connection, especially since the side 3c at least one transition area of the security ring 3 is connected on the inside to this film hinge connection 4, this film hinge connection 4 is offset to the outside with respect to the inner surface 3b of the security ring 3 and the transition area of the tab 5 ends in this film hinge connection 4. Preferably, as seen in longitudinal section, at least one side 3c adjoining at least one film hinge connection 4, in particular straight, is provided obliquely from bottom to top (see, for example, FIGS. 3, 6, 7, 9 and 12 to 18). As seen in longitudinal section in the production position, it is preferred to provide at least one side 5a, in particular straight, which adjoins the inside and / or outside on at least one film hinge connection 4 and runs obliquely from top to bottom (see, for example, FIGS. 3, 6, 7, 9 and 12 to 18 with regard to a side 5a) seen on the outside in the production position in longitudinal section adjoining the film hinge connection 4. At least one tab 5, seen in the production position, can be divided into several tab sections in terms of height. At least one tab 5 is preferably divided in height into two tab sections, an upper tab section 6 and a lower tab section 7 (cf., for example, FIGS. 1 and 3 to 19). The height-related separation of two tab sections from each other is usually assumed in the area of their kink or the like. Such a kink can be formed with sharp edges or with a radius inside and / or outside. If a tab 5 has no kink or the like, then the height separation into an upper tab section 6 and a lower tab section 7 is assumed. Preferably, seen in the production position in longitudinal section, the lower tab section 7 of at least one tab 5 extends from top to bottom and outwards to the upper tab section 6 of this tab 5 (cf., for example, FIGS. 3, 6, 7, 9 and 12 to 18 ). Such a spreading of the lower tab section 7 in the manufacturing position in longitudinal section viewed from top to bottom and outwards to the upper tab section 6 is of importance, while maintaining a small wall thickness, to achieve a large longitudinal streak with low transverse streakiness, which means that the arrangement is transverse to the circumferential direction of the tamper-evident closure 1 ribs (drawing not shown) corresponds. In addition, in the position of use, the upper tab section 6 of the respective tab 5 projects further from the inner surface of the safety ring 3, as can be clearly seen from, for example, FIG. 8. As a result, the circumferential tab length can be kept smaller, and due to the lack of ribs running transversely to the circumferential direction of the tamper-evident closure 1 (not shown in the drawing), the side 5a, seen in longitudinal section in the production position, can be at an extremely advantageously obtuse angle to the inner surface 6a of the upper tab section 6 run. Both in the production position, the upper tab section 6 and the lower tab section 7 can be further reinforced by reinforcing ribs running in the circumferential direction of the tamper-evident closure 1, which will be discussed later. Seen in the production position in longitudinal section, the inner surface 6b of the upper tab section 6 of at least one tab 5 can extend from the film hinge connection 4 in the axial direction from top to bottom or with respect to the longitudinal central axis L - L of the tamper-evident closure 1 at an angle - α - of in particular, extend 1 ° to 5 ° at an angle from top to bottom and outwards. Seen in the production position in longitudinal section, the inner surface 7b of the lower tab section 7 of at least one tab 5 can extend from the lower end of the upper tab section 6 of this tab 5 with respect to the longitudinal central axis L - L of the tamper-evident closure 1 at an angle - β - of in particular 5 Extend at an angle of up to 20 ° from top to bottom and outwards. In the production position, seen in longitudinal section, the inner surface 7b of the lower link section 7 of at least one link 5 can be at an angle - γ - of in particular 5 ° to 20 ° to the inner surface 6b of the upper link section 6 of this link 5 at an angle from top to bottom and to the outside extend. It is important for the stripping process with regard to a preferred removal of the plastic injection molded parts from the injection molding tool that no inner surface 6b, 7b protrudes inwards, because the plastic injection molded part must first be removed from the core and only later is pressed out of the stripper ring by a center ejector. Seen in the production position in longitudinal section, the outer surface 7a of at least one lower tab section 7 can extend at an angle of in particular 1 ° to 10 ° to the inner surface 7b of this lower tab section 7 obliquely from top to bottom and to the outside. The outer surface 6a and the inner surface 6b of at least one upper tab section 6 can, viewed in the production position in the longitudinal section, run parallel to one another (see, for example, FIGS. 3, 6, 7, 9 and 12 to 15). The outer surface 7a and the inner surface 7b of at least one lower tab section 7 can, viewed in the production position in longitudinal section, run parallel to one another (cf., for example, FIGS. 3, 6, 7, 9, 12, 13 and 16). In the production position, seen in longitudinal section, the lower tab section 7 of at least one tab 5 can be formed from top to bottom with a wall thickness that gradually widens (see, for example, FIGS. 14, 15, 17 and 18). Such widening of the wall thickness in the production position in longitudinal section, seen from the top downward of the lower tab section 7, enables its reinforcement. A gradual widening in the manufacturing position in longitudinal section from top to bottom is important for the stripping process a preferred demolding of the plastic injection molded part from the injection mold. Terms such as "from top to bottom", "from bottom to top", "upper", "lower", "up", "down", "in height", etc. are used in the explanations. These terms refer to an upright position of the tamper-evident closure 1, as shown in the drawings. The description and the claims are referred to as "versions". As is known, the container is not shown in the drawing. The "production position" of the tamper-evident closure 1 is the position before the flaps 5 are pivoted inwards, in which the tamper-evident closure 1 comes (is manufactured) from the injection molding tool. The two lateral outer boundaries of the respective tab 5 are referred to as “edge sides” 5b.

"Second bridges" 16 are bridges which are so weak that they tear open during the upward lifting movement of the tamper-evident closure 1. The second bridges 16 can be designed point-like or as material films. "First bridges" 17 are bridges which are so strong that they do not tear open during the upward lifting movement of the tamper-evident closure 1. The first bridges 17 can be designed point-like or as material films. Part of the circumference of the tamper-evident closure 1 is referred to as "partial circumference". If the transfer ring of the neck of the container is mentioned in the explanations, it can equally well be another suitable annular projection, provided that this is not excluded by the context, even if for the sake of simplicity no further details are given in the explanations.

The "subsequent opening process" is the opening process of the tamper-evident closure 1 after the second bridges 16 have been torn open. If there is an angle specification and the surface to which the angle specification is viewed in the longitudinal section, is curved or angled at least in sections, the course of an imaginary straight line running in the longitudinal section through the upper and lower end point of this surface is used to determine the angle. If the transition between two surfaces cannot be seen in a longitudinal section due to a corresponding curvature, the lower point seen in the longitudinal section is assumed to be the transition. If the upright position of the tamper-evident closure 1 is the production position, the position of use or the position of the tamper-evident closure 1 screwed onto the container neck, then this is indicated in detail in the explanations, if this is necessary. Seen in the production position in longitudinal section, the lower tab section 7 can start at least one tab 5 from a point offset at a distance downwards from its upper end or, in particular, from its upper end over part of its height or in particular its entire height from above be formed at the bottom with a widening wall thickness (cf., for example, FIGS. 14, 15, 17 and 18 with regard to one seen in the production position in longitudinal section from its upper end over its entire height formed from the top down with widening wall thickness lower tab section 7). This advantageously does not increase the wall thickness in the area of the kink or the like. When viewed in the longitudinal section in the production position, the height of the lower tab section 7 can be equal to or less than the height or in particular greater than the height of the upper tab section 6. The transition area between the upper tab section 6 and the lower tab section 7 of at least one tab 5 in its inwardly pivoted position (position of use) and in its center in the circumferential direction of the tamper-evident closure 1 can be in particular at the level of the transition area between the side 3c of at least one transition area and the inner surface 3b of the jacket Security ring 3 may be arranged. Seen in the production position in longitudinal section, at least one tab 5 or the upper tab section 6 of at least one tab 5 can extend from the film hinge connection 4 in the axial direction from top to bottom (see, for example, FIG. 9). In the manufacturing position, seen in longitudinal section, at least one tab 5 or the upper tab section 6 of at least one tab 5 can extend from the film hinge connection 4 with respect to the longitudinal central axis L - L of the tamper-evident closure 1 and spread outward from top to bottom ( see e.g. FIGS. 3, 6, 7 and 12 to 18). Seen in the production position in longitudinal section, the lower tab section 7 can extend as an extension to and at the same angle as the upper tab section 6 (not shown in the drawing). Preferably, at least one tab 5 and / or at least one upper tab section 6 and / or at least one lower tab section 7 is / are designed to be resilient or flexible with respect to its or its partial circumference at least in sections and / or in height at least in sections. This is important for the tab function, especially the swiveling inwards (position of use). On the inner surface 6b and / or in particular on the outer surface 6a of the upper tab section 6, as seen in the production position, of at least one tab 5, at least one in each case in the circumferential direction of the tamper-evident closure 1 over a part of its partial circumference, in particular at equal distances from its edge sides 5b or in particular Upper reinforcing rib 11 extending over its entire partial circumference may be provided. Seen in the production position in longitudinal section, at least one upper reinforcing rib 11 can extend from bottom to top, in particular from the transition area between the upper tab section 6 and the lower tab section 7 of at least one tab 5, over a part of the height or in particular the entire height of this upper tab section 6 ( see, for example, FIGS. 16 to 18 with regard to a reinforcing rib 11 which extends in the production position in a longitudinal section over the entire height of the upper link section 6). As a result, the wall thickness in the region of the kink or the like is likewise advantageously not increased, and nevertheless a reinforcement of the upper tab section 6 seen in the production position is achieved. At least one upper reinforcing rib 11 and / or at least one lower reinforcing rib 12 can have any suitable geometric shape, that is to say, for example, in the production position in longitudinal section, the shape of a trapezoid or the like or, in particular, at least essentially that Have the shape of a triangle or the like (cf. with respect to a triangular shape, as seen in longitudinal section in the production position, with respect to an upper reinforcing rib 11, for example, FIGS. 16 to 18 and with regard to a lower reinforcing rib 12, for example, FIGS. 15, 17 and 18). As seen in the longitudinal section in the production position, side 5a is preferably shorter than side 11a and extends at an obtuse angle to inner surface 6b than side 11a. As a result, the inner diameter between the upper tab sections 6 is kept as small as possible in the position of use and the upper tab sections 6 do not hinder the tamper-evident closure 1 from sliding over and over the transfer ring of the container neck, especially since only the lower tab sections 7 seen in the production position anyway to produce a resilient effect are important in the position of use. In addition, a gradual increase in wall thickness in the production position seen in longitudinal section of the upper reinforcement rib 11 from top to bottom and from bottom to top and to the outside and the lower reinforcement rib 12 from top to bottom and to the outside is created by such triangular shapes, which are beneficial to the stripping process affects a preferred demolding of the plastic injection molded parts from the injection mold. The lower reinforcing rib 12 seen in the manufacturing position should essentially serve to broaden the wall thickness of the locking flank 10 assigned to it, seen in longitudinal section in the manufacturing position, thereby preventing the respective tab 5 from buckling and thereby securely engaging under the transfer ring of the container neck to guarantee. Seen in the production position, at least one upper reinforcing rib 11 and / or at least one lower reinforcing rib 12 can have any number of sides. Preferably, as seen in the production position, at least one upper reinforcing rib 11 has two sides, an upper side 5a and a lower side 11b (see, for example, FIGS. 16 to 18) and at least one lower reinforcing rib 12 has a side 12a (see, for example 15, 17 and 18). Seen in the production position in longitudinal section, the lower side 11b of at least one upper reinforcing rib 11 can run at an angle of in particular 1 ° to 20 ° to the upper side 5a of this upper reinforcing rib 11 obliquely from top to bottom and to the outside. Seen in the production position in longitudinal section, the lower side 11b of at least one upper reinforcing rib 11 can run parallel to the longitudinal central axis L - L of the tamper-evident closure 1, the upper reinforcing rib 11 preferably being arranged on the outer surface 6a of the upper tab section 6 of the respective tab 5. Seen in the production position in longitudinal section, the lower side 11b of at least one upper reinforcing rib 11 can extend obliquely from below upwards and outwards or inwards with respect to the longitudinal central axis L - L of the tamper-evident closure 1, in each case after whether this reinforcing rib 11 is arranged on the outer surface 6a or inner surface 6b. The outer surface 6a and / or the inner surface 6b of the upper link section 6 and / or the outer surface 7a and / or the inner surface 7b of the lower link section 7 and / or at least one side of at least one reinforcing rib and / or the upper side 5a and / or the lower Side 11b at least one upper reinforcing rib 11 and / or side 12a at least one lower Reinforcing rib 12 can have any suitable geometric shape, that is to say, for example, when viewed in the production position in longitudinal section, at least in sections concave or convex, in the form of a circular section or in a shape similar to a circular section or the like or in the form of an elliptical section or in the form of an elliptical section or the like or in a parabolic section Form or the like or in the form of a sinusoidal section or in the form of a sinusoidal section or the like or in the form of a hyperbola section or in the form of a hyperbolic section or the like or similar in the form of an oval section or in the form of an oval section or the like. The respective transition between two surfaces can be provided with sharp edges, continuously or in the form of a radius. On the inner surface 7b and / or in particular the outer surface 7a of the lower longitudinal section 7, seen in the production position, of at least one tab 5, at least one each, in the circumferential direction of the tamper-evident closure 1 over a part of its partial circumference, in particular at equal distances from its edge sides 5b or in particular Lower reinforcing rib 12 extending over its entire partial circumference may be provided. In the production position, seen in longitudinal section, at least one lower reinforcing rib 12 can extend from a point located at a distance downwards from the upper end of the lower tab section 7 of at least one tab 5, in particular over the entire remaining height of this lower tab section 7 from top to bottom (see, for example, FIGS. 15, 17 and 18 with regard to a lower reinforcing rib 12). Seen in the production position, at least one lower reinforcing rib 12 can be formed with a wall thickness that in particular gradually widens from top to bottom (see, for example, FIGS. 15, 17 and 18). A wall thickness, in particular gradually widening from top to bottom in the manufacturing position in the longitudinal section, is important for the stripping process with regard to a preferred demolding of the plastic injection molded parts from the injection molding tool. Seen in the production position in longitudinal section, the side 12a of at least one lower reinforcing rib 12 arranged on the outer surface 7a of the lower tab section 7 of at least one tab 5 can be inclined at an angle of in particular 10 ° to 40 ° to the inner surface 7b of this lower tab section 7 from top to bottom and run outwards. In the production position seen in longitudinal section, the side 12a of at least one lower reinforcing rib 12 arranged on the inner surface 7b of the lower tab section 7 of at least one tab 5 can be inclined at an angle of in particular 10 ° to 40 ° to the outer surface 7a of this lower tab section 7 from top to bottom and run inside. Seen in the production position, at least one lower reinforcement rib 12 can be arranged on the lower tab section 7 of at least one tab 5 at its lower end (see, for example, FIGS. 15, 17, 18 and 19). Seen in the production position in longitudinal section, the height of the side 12a of at least one lower reinforcing rib 12 can be equal to the height or greater than the height or in particular smaller than the height of the outer surface 7a and / or inner surface 7b of the lower flap section 7 above it and at least one flap 5 be (see, for example, FIGS. 15, 17, 18 and 19 for a lower reinforcing rib 12, the Height is smaller than the height of the outer surface 7a located above it, especially since, seen in the production position in longitudinal section, the lower reinforcing rib 12 should preferably serve to increase the wall thickness of the locking flank 10). At least one locking flank 10 can be offset over a part of its partial circumference in the circumferential direction of the tamper-evident closure 1 in the center or starting from at least one outer end in the direction of the center or in the region of at least one outer end and in the production position in longitudinal section from top to bottom and in particular from the outside be tapered inwards in particular (cf. with regard to the circumferential direction of the tamper-evident closure 1, for example, FIG. 5 with regard to a central arrangement and, for example, FIG. 4 with regard to an arrangement in the region of an outer end and with regard to the production position in a longitudinal section, for example, FIG. 6 and 9 with regard to a wedge-shaped taper from outside to inside and from top to bottom). From the outside to the inside, in the manufacturing position, seen in longitudinal section from the outer surface to the inner surface. If, for example, a lower reinforcing rib 12 is arranged on the outer surface 7a of the lower tab section 7 at its lower end, as seen in the production position, "in the production position in longitudinal section from the outside 12a of this lower reinforcement rib 12 to the inner surface 7b means this in the production position lower tab section 7. This also applies accordingly to the outer surface 13a and the inner surface 13b of at least one lug 13. "Wedge-shaped" generally means that in the production position, seen in longitudinal section, the outer surface runs obliquely from top to bottom towards the inner surface, but can also mean that the outer surface and the inner surface run obliquely from top to bottom. This also applies accordingly to the outer surface 13a and the inner surface 13b of at least one lug 13. The wedge-shaped profile seen in the longitudinal section in the production position does not preclude an at least partial curvature of the respective surface (eg outer surface 13a and / or inner surface 13b of at least one lug 13) . For the sake of simplicity, the wedge-shaped tapering of the respective locking flank 10 is seen in longitudinal section in the production position, although strictly speaking the lower end of the tab 5 assigned to it or the lower tab section 7 assigned to it is tapered in a wedge shape. At least one rib 14 can be offset in the circumferential direction of the tamper-evident closure 1 in the center or starting from at least one outer end in the direction of the center or in the area of at least one outer end of at least one tab 5 or the lower tab section 7 of at least one tab 5 and / or in seen in the longitudinal section of the manufacturing position at least at its lower end from top to bottom and in particular from outside to inside in particular wedge-shaped. The respective embodiment of the tamper-evident closure 1 is decisive for the position of the sections and ribs which are tapered in the longitudinal section in the production position. With regard to the position and meaning, the later explanations with regard to the lugs 13. At least one rib 14, seen in longitudinal section in the production position, can extend over the lower end of at least one tab 5 or over the lower end of the lower tab section 7 at least one tab 5 extend downwards sufficiently (cf. e.g. Fig. 9). Seen in the production position in longitudinal section, the upper tab section 6 and / or the lower tab section 7 or at least one tab 5 can be spread apart from top to bottom and outwards and the inner surface of at least one rib 14 cannot have an imaginary line AA inwards crossing or running according to this imaginary line A - A (see, for example, FIG. 9 for a rib 14 arranged on the inner surface 7b). It is important for the stripping process with regard to a preferred demolding of the plastic injection molded parts from the injection molding tool that the respective rib 14, seen in longitudinal section in the production position, does not protrude inwards. At least one locking flank 10 or at least one nose 13 extending from top to bottom in the longitudinal section in the production position can be arranged (see, for example, FIGS. 10, 11, 12 and 17, and also FIG. 19) Combination of FIGS. 11, 17 and 18). In the production position, seen in longitudinal section, at least one nose 13 can taper in a wedge shape from top to bottom and from outside to inside (see, for example, FIGS. 12 and 17). Such a wedge-shaped taper seen in the production position in longitudinal section prevents the respective tab 5 from being pressed under the transfer ring of the container neck after the second bridges 16 have been torn open during the subsequent opening process, because the outer surface, as seen in longitudinal section in the production position 13a of the respective nose 13 slides past the transfer ring of the container neck and thus prevents the respective tab 5 from unfolding into the production position. Seen in the production position in longitudinal section, at least one nose 13 can, in particular, taper in a wedge shape from top to bottom and in particular from outside to inside. Seen in the production position in longitudinal section, at least one lug 13 can start from a point below the point between it and the locking flank 10 assigned to it or, in particular, from the connection area between it and the locking flank 10 assigned to it, over a part of the height or in particular the entire height run from top to bottom and in particular from outside to inside in particular in a wedge shape (cf., for example, FIGS. 12 and 17 with regard to a longitudinal section seen in the production position from the connection area between it and the locking flank 10 assigned to it, starting from the top over its entire height below and from the outside inwards tapered nose 13). In the circumferential direction of the tamper-evident closure 1, at least one nose 13, which extends over part of the partial circumference or at least one locking flank 10, can be offset on this locking flank 10 in the middle or starting from at least one outer end in the direction of the center or in the area of at least one outer one Be arranged at the end. The corresponding embodiment of the tamper-evident closure 1 is decisive for the position of the respective nose 13 in the circumferential direction of the tamper-evident closure 1 on the locking flank 10 assigned to it. 11 and 19, the first bridges 17 lie in the circumferential direction of the tamper-evident closure 1 in such a way that the respective security ring section tears open at both outer ends, while in the embodiment of the tamper-evident closure 10, for example, a first bridge 17 is preferably provided in the region of the outer end, on which the nose 13 is arranged, and the respective safety ring section is torn open at the opposite end. With such an arrangement of the nose 13 in the circumferential direction of the tamper-evident closure 1 at the outer end on a locking flank 10, this is probably not only necessary to prevent the tab 5 assigned to it after the second bridges being torn open during the subsequent opening process under the transfer ring of the container neck can be pressed, but is also required for second bridges 16 which have not yet been torn open when opening for the first time to run onto the transfer ring of the container neck.

This also applies correspondingly to the embodiment according to FIG. 5. The outer surface 13a and / or the inner surface 13b of at least one nose 13 preferably runs straight, as seen in the production position in longitudinal section (cf. for example FIGS. 12 and 17). As seen in longitudinal section in the production position, the in particular straight inner surface 13b of at least one nose 13 preferably extends in the axial direction (cf., for example, FIG. 17). This serves to improve the plastic injection molding tool, because the additional steel rings containing the indentations for the lugs 13 have cylindrical bores and can therefore be adapted more easily than conical surfaces. Seen in the production position in longitudinal section, the inner surface 13b of at least one lug 13 can also extend as an extension of and at the same angle as the inner surface of the lug 5 assigned to this lug 13 or the inner surface 7b of the lower lug section 7 of the lug 5 assigned to this lug 13 (see e.g. Fig. 12). The section or sections of at least one locking flank 10 lying in the circumferential direction of the tamper-evident closure 1 next to at least one nose 13 preferably run straight and preferably at right angles to the longitudinal central axis L - L of the tamper-evident closure 1 ( see e.g. Figs. 14, 15 and 18). The sections of the locking flank 10 assigned to it in the circumferential direction of the tamper-evident closure 1 next to a lug 13 are, seen in the production position in longitudinal section, straight and at right angles to the longitudinal central axis of the tamper-evident closure 1, even if the respective tab 5 or the lower tab section 7 the respective tab 5 is spread outwards. This simplifies the injection molding tool, because the steel rings that form the safety ring 3 and the tabs 5 are then only ground flat, which furthermore facilitates the height adjustment of the individual steel rings in relation to the core, which saves time and thus also costs. In the position of use, the desired effect is a slight tapering of this locking flank 10 in the longitudinal direction in the direction of the outer surface and thus a better grip under the transfer ring of the container neck. Seen in the production position in longitudinal section, the wall thickness of at least one lug 13 in the connection region with the locking flank 10 assigned to it can be greater or smaller than the wall thickness of this locking flank 10 (not shown in the drawing). The wall thickness of at least one lug 13 in the connection area with the locking flank 10 assigned to it is preferably equal to the wall thickness of this locking flank 10 (cf., for example, FIG. 12 and 17). Seen in the production position, at least one rib (14) arranged on the outer surface and / or on the inner surface of at least one tab 5 or on the outer surface 7a and / or on the inner surface 7b of the lower tab section 7 can be inserted into the respective nose 13 extend or end above this nose 13. In the circumferential direction of the tamper-evident closure 1, at least one section of this locking flank 10 located in the manufacturing position in the manufacturing position next to at least one section of at least one locking flank 10 and / or tapered in particular in a wedge shape as seen in longitudinal section in the manufacturing position in the manufacturing position in FIG Longitudinal section seen from the inside to the outside and from top to bottom or in particular at right angles to the longitudinal center axis L - L of the tamper-evident closure 1 (see, for example, FIGS. 7 and 13). In the circumferential direction of the tamper-evident closure 1, at least one locking flank 10 can be at least over part of its partial circumference or the outer surface and / or the inner surface of at least one section of at least one locking flank 10 and / or the outer surface and / or the inner surface of at least one rib 14, particularly wedge-shaped in the longitudinal section in the production position and / or the outer surface 13a and / or the inner surface 13b of at least one nose 13, particularly wedge-shaped pointed in the longitudinal section in the production position, have any suitable geometric shape, for example , seen in the production position in longitudinal section, at least in sections concave or convex, in the form of a circular section or in a shape similar to a circular section, or the like. or in an elliptical section or in an elliptical section like shape or the like or parabolic section-like or in parabolic section-like shape or the like or sinus-like section or in sinus-like shape or the like or hyperbolic section-like or hyperbolic section-like or the like or oval section-like or oval section-like shape or the like curved or at least straight in particular be straight. The respective transition between two surfaces can be provided with sharp edges, continuously or in the form of a radius. Seen in the circumferential direction of the tamper-evident closure 1 and / or in the production position in longitudinal section, the particular wedge-shaped tapering of at least one section or at least one section 10a of at least one locking flank 10 and / or at least one rib 14 and / or at least one nose 13 can, in particular, gradually merge into one another be formed (cf., for example, FIG. 9 with regard to the stepless transition in the production position seen in longitudinal section of a wedge-shaped tapered section 10a of the locking flank 10 and a wedge-shaped tapered rib 14). At least one section of at least one locking flank 10 and / or at least one section of at least one locking flank 10 and / or at least one rib 14 and / or at least one nose 13, as seen in the longitudinal section in the manufacturing position, in particular wedge-shaped, can the transfer ring of the container neck in the reach under the screwed-on position of the tamper-evident closure 1 or in a particularly slight position Distance to be arranged. The sections 10a and ribs 13 and lugs 14, seen in particular in the longitudinal section in the production position, are not intended to be clamped between the transfer ring and the inner surface 3a of the security ring 3 when the tamper-evident closure 1 is screwed onto the container neck, but rather to during the subsequent opening process after the second bridges 16 have been torn open, slide past the transfer ring of the container neck without being pressed under them and thereby prevent the tabs 5 from folding back into the production position. Seen in the production position, at least two different sections of at least one locking flank 10 can be separated from one another by slots (not shown in the drawing) that are particularly short and in particular transverse to the circumferential direction of the tamper-evident closure 1 (not shown in the drawing). Seen in the production position, at least one and / or a slot (not shown in the drawing) and / or extending groove (in the drawing) that extends or runs in particular transversely to the circumferential direction of the tamper-evident closure 1 and extends from bottom to top into the lower tab section 7 not shown) may be provided (not shown in the drawing). Seen in the production position in longitudinal section, the height of at least one tab 5 and / or the height of at least one tab 5 including at least one rib 14 and / or nose 13 arranged on it can be greater or less than the height of the safety ring 3. When viewed in longitudinal section in the production position, the height of at least one plate 5 and / or the height of at least one plate 5 including at least one rib 14 and / or nose 13 arranged on it is preferably equal to the height of the safety ring 3 in particular, ribs running transversely to the circumferential direction of the tamper-evident closure 1 (not shown in the drawing) on the outer surface and / or on the inner surface of at least one tab 5 or on the outer surface 7a and / or on the inner surface 7b of the lower tab section 7 of at least one tab 5, in particular uniformly trained and / or arranged regularly (not shown in the drawing). The safety ring 3 or at least one safety ring section (section of the safety ring 3) can be connected to the screw cap 2 via at least one first bridge 17 and / or at least one second bridge 16 (cf., for example, FIGS. 1, 2 and 19 for two first bridges 17).

The safety ring 3 can have at least one slot 15, in particular running in the axial direction, with at least or in each case one second bridge 16 extending over its entire height (not shown in the drawing). The safety ring 3 can, however, also have at least one slot 15, in particular in the axial direction, with at least or in each case a second bridge 16 extending over part of its height (cf., for example, FIG. 3). At least or in each case one security ring section (section of the security ring 3) can be connected to the screw cap 2 in the circumferential direction of the tamper-evident closure 1, in each case via a first bridge 17 extending over a part of its partial circumference at, in particular, the same distances from the slits 15 delimiting it ( graphic not shown). At least or one safety ring section (section of the safety ring 3) can extend in the circumferential direction of the tamper-evident closure 1 over two first ones over a part of its partial circumference with, in particular, equal distances from its center and with, in particular, equal distances from the slots 15 delimiting this safety ring section Bridges 17 may be connected to the screw cap 2 (see, for example, FIG. 19). When a slot 15 is mentioned in the explanations, it is of course also meant its second bridge or bridges 16, provided that these are still undamaged, even if for the sake of simplicity no further details are given. Seen in the production position, in the circumferential direction of the tamper-evident closure 1, the locking flank 10 of at least one tab 5 can be concavely curved at least in sections from bottom to top (not shown in the drawing). As seen in the production position, the locking flank 10 of at least one tab 5 is preferably straight in the circumferential direction of the tamper-evident closure 1 (see, for example, FIGS. 1, 3, 4, 5, 10, 11 and 19). A locking flank 10 which is straight in the manufacturing position has the effect that, in the position of use in the area of the outer ends, it is at a height from the underside of the transfer ring of the container neck, does not engage under it in the area of its outer ends and thus when pressed in the direction of the inner surface 3b of the safety ring 3 for the purpose of manipulation jumps back into the starting position. As a result, the tamper-evident closure 1 according to the innovation can be manipulated to a maximum degree. Seen in the production position, the edge sides 5b of at least one tab 5 can be designed to widen or taper from bottom to top (not shown in the drawing). As seen in the production position, the edge sides 5b of at least one tab 5 preferably run transversely to the circumferential direction of the tamper-evident closure 1 and parallel to one another (see, for example, FIGS. 4, 5, 10 and 11). At least one tab 5 can extend in the circumferential direction of the tamper-evident closure 1 over the entire partial circumference of at least one security ring section delimited by two slots 15 (not shown in the drawing). Preferably, in the circumferential direction of the tamper-evident closure 1, at least one tab 5 extends over part of the partial circumference, in particular at equal distances from the slots 15 delimiting it (cf., for example, FIGS. 4, 5, 10 and 11). If, seen in the production position, the edge sides 5b of a tab 5 run transversely to the circumferential direction of the tamper-evident closure 1 and parallel to one another, it is important that this tab 5 does not extend over the entire partial circumference of the security ring section assigned to it. A “safety ring section” is a section of the safety ring 3 delimited by two slots 15 in each case. If the safety ring 3 is mentioned in the explanations, then, if this is not excluded by the context, the respective safety ring section or the respective safety ring sections may also be meant, even if for the sake of simplicity the details are not always mentioned in the explanations becomes. Preferably, at least one film hinge connection 4 extends in the circumferential direction of the Tamper-evident closure 1 over the entire partial circumference of at least one tab 5 (see, for example, FIGS. 4, 5, 10 and 11). In the circumferential direction of the tamper-evident closure 1, at least one of the first bridges 17 can be arranged in the area of an outer end of at least one safety ring section (section of the safety ring 3) and at least one each, seen in longitudinal section in the production position, in particular in a wedge shape tapered section 10a of at least one locking flank 10 and / or at least one rib 14 and / or at least one nose 13 in the region of this outer end of the tab 5 associated with this safety ring section or in the circumferential direction of the tamper-evident closure 1 at least or each a first bridge 17 may be arranged in the center or in the middle of at least one or each safety ring section extending over a part of its partial circumference, or at least one or two first bridges 17 with in particular equal distances from the center of at least one safety ring section Itts be arranged extending over a part of its partial circumference and at least one section 10a of at least one locking flank 10 and / or at least one rib 14 and / or at least one nose as seen in longitudinal section in the manufacturing position 13 may be arranged in the center or in the middle of the tab 5 assigned to this safety ring section (cf. e.g. Fig. 19). An embodiment according to, for example, FIG. 19 allows a particularly strong desired stiffening and tensioning between the respective safety ring 3 and the tab 5 assigned to it in the position of use. At least one safety ring section (section of the safety ring 3) which is provided without a tab 5 and is at least essentially rigid can be connected to the screw cap 2 in the circumferential direction of the tamper-evident closure 1 and via at least one first bridge 17 which extends over its entire partial circumference and in particular has a stronger design / or connected to the screw cap 2 via at least one connecting web 18, which is arranged in the center in the circumferential direction of the tamper-evident closure 1 (see, for example, FIGS. 1, 2 and 19). By means of such security ring sections without tabs 5, the tearing open of the security ring sections is shortened because the security ring sections without tabs 5 do not or hardly move with the security ring sections during the first opening operation and in this way tend to tear open the second bridges 16. If the versions refer to a safety ring section, then it is a safety ring section (section of the safety ring 3). If a safety ring section without tabs 5 is meant, the addition "without tab" 5 indicates this. At its lower end, the screw cap 2 can have an especially ring-shaped, outwardly widened, in particular thin-walled collar (not shown in the drawing) have and this collar (not shown in the drawing) have at least in the region of the first bridges 17 and / or the second bridges 16 a wall thickness increased in particular by the remaining wall thickness of the screw cap 2 (not shown in the drawing). Such a collar (not shown in the drawing) engages over the safety ring 3 or its safety ring sections, which may protrude outwards when torn open. The increase in wall thickness only in the area of the first bridges 17 and / or second bridges 16 serves to save material in the otherwise thin-walled collar (not shown in the drawing). At least one second bridge 16 can be tapered, seen in longitudinal section from bottom to top. At least a first bridge 17 and / or at least a second bridge 16 can be offset in the circumferential direction of the tamper-evident closure 1 in the center or starting from an outer end towards the center or in the area of at least one outer end of at least one security ring section (section of the security ring 3) be arranged (cf. in this connection the explanations regarding the lugs 13 in connection with the first bridges 17). Seen in the production position in longitudinal section, the particular wedge-shaped tapering of at least one section of at least one locking flank 10 and / or at least one section 10a of at least one locking flank 10 and / or at least one rib 14 and / or at least one nose 13 can be seen at an angle of in particular 10 ° to 45 ° to the longitudinal central axis L - L of the tamper-evident closure 1. At least two or the safety ring sections and / or safety ring sections without tabs 5 and / or film hinge connections 4 and / or tabs 5 and / or edge sides 5b and / or upper tab sections 6 and / or lower tab sections 7 and / or in the production position seen in longitudinal section in particular Wedge-shaped tapered sections 10a of at least one locking flank 10 and / or upper reinforcing ribs 11 and / or lower reinforcing ribs 12 and / or reinforcing ribs and / or lugs 13 and / or ribs 14 and / or slots 15 and / or second bridges 16 and / or first bridges 17 and / or connecting webs 18 and / or ribs (not shown in the drawing) and / or slots (not shown in the drawing) and / or grooves (not shown in the drawing) within the tamper-evident closure 1 arranged circumferentially irregularly or in particular regularly and / or non-uniformly or in particular uniformly trained un d / or be arranged. The tamper-evident closure 1 is preferably constructed in one piece. The tamper-evident closure 1 is preferably made of a suitable plastic, preferably relatively hard, in particular medium-hard to hard plastic with less elongation, in particular polypropylene or or polyethylene or a material with similar physical properties. All of the above-mentioned embodiments of the tamper-evident closure 1 can also be combined with one another as desired, provided this is not excluded by the context. The illustrated embodiments of the tamper-evident closure 1 according to the innovation are not tied to the dimensions shown in the diagrams, but rather can be produced in any dimensions depending on the requirements (e.g. DIN standards). The geometry and dimensions of the tamper-evident closure 1 or its tamper-evident closure parts can be realized as required, in particular for better adaptation to containers. Possibilities of use that only require structural measures can be expanded as desired.
