(54) Title: TAM PER-PROOF CLOSURE (54) Bezeichnung: ORIGINALITATSVERSCH-LUSS .13 3d 3a 3 (57) Abstract A tamper-proof closure has an internal screw-thread which can be screwed on to a complementary counter-screw on a container neck, a screw cap possibly provided with separate sealing means, for sealing the container mouth, and a security ring connected to the bottom of the screw cap Sp~ ring can be torn off, or has means for tearing it off, the screw cap at least in sections. At least one inwardly-pivoting tab connected to the bottom of the safety ring via a hinge or Film hinge connection is provided for gripping a transfer ring arranged on the container neck below the counter-screw. Preferably the locking flank (10) of at least one tab has at least one section, in particular a levelled section (IlOa), and/or at least one rib (14) and/or in particular at least one projection Preferably at least one tab is subdivided into appropriately-shaped and arranged tab sections, in particular into a lower tab section which expands downward and outward from an 'ipper tab section Preferably reinforcing ribs (11, 12) are suitably disposed around the periphery of the tamper-proof closure -1- TAMPER-PROOF CLOSURE The invention deals with a tanmer-proof closure for containers like canisters, bottles and the kind, made of plastics, glass etc., in particular returnable bottles whose container neck features a helical counter thread and a transfer ring Can annular projection) underneath that helical counter thread.

Tamper-proof closures have the purpose to indicate that the closure of a container has been tanpered with, has been opened, i. e. by the intact state of the integral tanper-proof closure, the consumer is assured of the original contents of the container, as warranted.

The natter is a novel tamper-proof closure having a screw cap with an internal matching thread screwable onto a complementary helical counter thread of a container neck, said screw cap is provided with a -if need be specifically formed- sealing means for sealing the container mouth, said closure featuring a safety ring downwardly attached to said screw cap. Said safety ring is provided detachable for getting torn off screw cap at least in sections and/or is fracturable embodied.

At least one tab downwardly attached to said safety ring via a film hinge connection is inwardly swivelling (utilitarian position) for the purpose of engaging under a transfer ring of container neck, positioned underneath the helical counter thread.

It is known to design a tamper-proof closure with cans arranged on the inner face of safety ring, tightly engaging under the transfer ring of c, -2 container neck, that have the effect to cause expansion of the safety ring as a whole when flexed over the container neck; this surely makes embiodiment of a breakable safety ring probaaratical. ir it is indispensable for returnable bottles in order to avoid an additional working operation that the safety ring, after splitting open, is left with the screw cap and does not stick to the container- neck. Here again grave difficulties arise in designing a breakable and splitting embodied safety ring; the question is its tolerable expansion as a whole.

Because of large tolerances of glass bottles due to oval compasses in addition to the pilfer-proof short-thread condition, the safety ring doe. ,iot burst when the closure is opened for 'the first tine by the unscrewing process, but needs to be torn off the container to get rid of. industry as well as consumers regard this as disadvantageous.

ther mis-chances are the complicated injection-mould tool for manufacturing such a closure and application of special capping heads for capping <the mechanical capping> to facilitate working up those closures at all at automratically operating closing mchines of high working speed. In addition, the safeguard against tanpering as warrantedca be manipulated bysimple eans in such away that an opening of the closure is possible also without affecting the tant~er-proof safeguard of originality. on the strength of such grave disadvantages, that kind of tanVwer-proof closures hold their grounds in the market but insufficiently, and almost do not make their way into the market of returnable bottles at all.

Embodimrent of taby4 dowmiwardly depending from safety ring and inwardly -3 swivelling (utilitarian poston), hoawever, enables an easy flexing over the container neck, as the barb-like formed tabs, joined to the safety ring both easily slide over the container neck and serriedly lock below the transfer shoulder of the container neck at the first attempt to open the container. This condition renders the opportunity of subdividing the safety ring by laying out several un-crackable connection points and therefore distinctly thin fracture points within several rather fracturable emrbodied sections (sections of safety ring), thus warranting the splitting of safety ring to occur already with the unscrewing process in first opening of closure and not but finally by ripping it away frm the container. In addition, the novel tanperproof closure still looks well-designed also in evidently burst condition, something which is not a matter of course at conventional tamrperevident closures in general.

Furthernmire the structure of the injection tool is positively simple and thereby of favourable estimrate of cost, also warranting the employmerit of conventional capping heads because of the easy flexing over the container neck even at high speed operation. Moreover, security fromn manipulation is granted, for the positively thin f ormed fracture points would not withstand an aittempt of manipul.ation.

These are decisive aspects for a tamper-proof closure prevailing on the market or failing.

With first opening of the tatiper-proof closure a deformration of the respective section of safety ring in connection with the depending tab takes place in such a way t1hat both parts will bend outward, and the -4radius of the section of safety ring will get zmaller. Then the tab yields to buckling centrically in circu.ferential direction of the tamper-proof closure, towards said section of safety ring, whereby this section of. safety ring and the tab get stiffened as much as if the tab would not afterwards have swivelled inwards (in utilitarian position), but were manufactured in that position together with the safety ring.

In consequence the tab does not centrically grip and contract in circumferential direction of the tanper-proof closure underneath the transfer ring of the container neck, and guarantee is assumed of the tab not catching in as a whole underneath the transfer ring of container neck whereby the tab cannot again be downwardly hinged into the moulded position upon screwing the cap. This aforementioned defornation and stiffening is ensured through the fracture points of safety ring which put up so much resistance to the section of safety ring and to the tab prior to their bursting, that hereby the necessary deformation and stiffening are enabled.

If nevertheless the taTrper-proof closure, with safety ring splitted, should be screwed onto the container zieck anew and be unscrewed off it, then it might happen, depending of handling, a tab will again get opened and be downwardly extended into moulded position, because of lacking deformation and stiffening, due to the splitting, given the correspondingly short length of tab, e. g. when during the subsequent opening a thumb presses sustainingly on the section of safety ring, turning it at the same time, and thus forcing the appropriate tab to get flexed centrically under the transfer ring of container neck in circumferential direction of the tamper-proof closure. Such tamperproof cl osures woul d not have any chance at all1 in the mg rket. This ef fect can be avoided on designing a respectively great circumferential length f or the tabs.

That, however, affects adversely again, particularly when the safety ring is subdivided into sections, as with increasing length of section of safety ring also the tension rises which the tab that is allocated to this section, exerts onto it in the inwardly swivelled position (utilitarian position). That is the reason why after bursting, the distal ends of section of safety ring unpleasantly bend outward, which it) has an awkward effect on the screwing and reduces the aesthetic and hence sales-prarmoting impact. Under particularly high tension there is even the danger that the closure assumes a slightly polygonal shape, fracture points not having crack*d yet. Ainother possibility for avoiding the above-noted effect consists in providing the tabs with locking f lanks that, seen in mo~ulded position, are f ran below upward concavely curved, wherein, in the position of cloxsure after having been screwed onto container neck, every locking flank in circumferential direction of th~e tamper-proof closure centrically per section of safety ring is kept apart fromn the transfer ring of container neck in a certain distance.

But also this option proves to be disadvantageous. on the one hand the security f rcz maenipulation of the novel tanper-proof closure is impaired that way, because the distal ends of the respective tab, in the position of tanper-proof closure having been screwed onto the container neck, are no longer kept apart in an elevational distance frcom the transfer shoulder of container neck, but tightly engage it directly, whereby, already upon beginning to turn the screw cap, these ones -6might be forced by a manipulatory object, e. g. a screw-driver, past the transfer ring and so the tanper-proof closure can be unscrewed without fracture points breaking. On the other hand, there is the further disadvantage of the technical expenditure for making locking flanks with such concave vaults. To this end, several electrodes and a jufr spark erosion process are required, where also the manufacture of these electrodes is expensive and complicated owing to curvatures in several slopes. Moreover, measuring and changing each sirSie steel ring of the injection-mould tool to the appropriate elevational height requires time-consuming and expensive set-up procedures.

Therefore the executions present facilities of particularly cut on-theslant tapering sections of the locking flank, ribs and projections and the kind, where with regard to the injection-mould tool for plastics, the projections (lugs) are most simply rmanufacturable, as they can be fotned by merely milling in indentations into a thin supplementary ring of the injection-mould tool. By face grinding proceedings the elevational adjustnent of each single steel ring of the injection tool is again quite unproblematic. The above-mentioned executions effect in a way that the respective tab, safety ing being burst, cannot again be pressed in order to engage below transfer ring during later opening of the tanper-proof closure, but will slide past it. Furthermore, by these facilities security from manipulation of the novel tarper-proof closure will not be impaired which is of *tirist inportance.

Another problem is the sublime longitudinal body, with transversal body correspondingly low, as requisite for tabs formed like that. This problem can be solved by arranging ribs on the outer surface and/or inner "i -7surface of the respective tab, that defile askew to circumferential direction of the tanper-proof closure. That kind of ribs, however, pose certain other problems on their part. They produce an Mdisirable increase of superficies. If one wants to avail oneself of a profitable remving fran the mould procedure of the plastic casting, then the tabs must be pushed out of the stripper-ring by a central knock-out, thereby being inwardly janmed together. Here you have to consider the tabs being joined to the safety ring via thin film-hinge connections.

If already, inplied by the function, the rib and hence its respective tab including ribs nust be appropriately wide seen in elevational sectional view, moulded position, in order to achieve great longitudinal body, then the necessary width will be even greater by the fact that the angle between side (5a) of tab and outer surface and/or inner surface thereof must get correspondingly acute to enable removing the tamper-proof closure fran the mould of the plastic moulding injection tool. Therefore the wall-thickness/substance of the tabs is instrumental for the angle of side (5a) of at least one transition area of tab concerned, i. e. this angle to the outer surface and/or miner surface of the tab concerned is getting acute in proportion to the adding of substance to the respective tabs. By such an acute angle of side the tab is unnecessarily weakened,and its deflection just in this range is the result. That can be caopensated only by a width of tab including the x.bs, seen in elevational sectional view, moulded position, greater than that functionally iniplied anyway. It reains to be established as a result that in doing so, said width of tab including ribs has become as great as that the safety ring will outwardly exceed the screw cap which considerably detracts fram the aesthetic and 8 hence sales-prcmoting effect of the tamper-proof closure.A further grave disadvantage of such a rib forming is the manufacture of this companent of injection-mould tool. As a rule, the tabs are formed through an internal outline evolving out of the inner face of a ternpered steel ring by a process of juMp spark erosion, said steel ring then being inserted into the stripper-ring of the plastic moulding injection tool, and its core being set up n the running surface, in other words, this is a working part which must be manufactured in miltiple copy for a multiplex tool and be hold in reserve as a spare part. It is to be regarded as a constant advantage, in particular with such a mass-produced article, when working parts ae configured as simple as ever possible. That, however, is not so with the aforementioned rib embodiment; for on the one hand the electrode, anyway expensive in manufacture because of the acute-angled ribs and their utmost exactness, also wears down very fast, on the other hand, ini addition, either there are required several supplementary electrodes for a finishing post-erosion of the roughing, where burnishing the steel rings thus is made considerably easy, or the rings as eroded in the roughing step are directly burnished which, however, does not essentially reduce the cost. The pragmatical value was ascertained that, calculated to each ring and to each person, an eight-hour working day does not fully suffice to high-polish one single steel ring for all special tools. employed, as the areas between those narrow ribs are but hard to burnish, taking up a great deal of time. For this reason, the executions propose tabs provided without ribs defiling transversal to circumferential direction of the tamper-proof closure and to obtain the right proportion betwe n lngitudinal and transversal body by subdivid- -9ing the tabs into appropriately formed and spaced-apart tab sections, in particular designing to each subdivided tab one lower tab section, seen in moulded position in elevational sectional view, as for an upper tab section from above downwardly and outwardly opened out, and disposing for appropriate reinforcemant ribs running in circumferential direction of the tamper-proof closure, in these tab sections.

After this solution the tabs feature but even surfaces, and the electrode required for eroding the steel rings is but a turning part. The electrode consumption is extremely low because of forming even surfaces, and high-polishing of rings eroded even during the roughing step presents no problem. Costs and the time spent on manufacturing these rings can hereby be reduced to a fraction. Right for this sort of mass-produced article having a very closely calculated final price, the aspect of economy is a primary consideration, especially since, due to the high number of pieces of production, the injection-mould tools are subject to an increased wear and tear. But good optical effect and hence the sales-promoting impact play an important part, too.

As the above-described deformation and stiffening are not achievable there, it is not considered to go into in more detail in this c mection to the State of the Art concerning tamper-proof closures with also inwardly swivelling tabs where, however, the attribute of a stay via a stopping device against the safety ring and placed above a hinge or else film-hinge connection, so as to range throughout the relative height in no way irrelevant of said safety ring, is lacking.

10 To sun up it can be established that the novel tamper-proof closure meets all requirements one must put a great strain on, both in respect of feeling for design, geniality of operating easy handling, security frcm-manipulation and in respect of its applicability when using conventional capping heads for capping (the mechanical closing);in particular it can be manufactured as a mass-produced article of favourable estimate of cost by an exceedingly sinple constructed and hence reasonable injection-mould tool working in a less trouble-pronemanner.

Preferably at least one tab 5 in the position after having inwardly swivelled (utilitarian position) above at least one hinge or else film hinge connection 4 is supported over a range not irrelevant of its relative height by at least one stopping device against safety ring 3 As "utilitarian position" is designated that position of tamper-proof closure 1 in which tabs 5 are hinged comparatively in- 13 wards. It is preferred at least one stopping device, in moulded position, seen in elevational sectional view, feature at least one transition area of safety ring 3 and/or of at least one tab 5 said transition area gradually tapering, at least minly, toward the swivel axis of at, least one binge or else film binge connection 4 and at least bearing over the partial circumnference the arc segmrent of at least one tab 5 The executions e. g. according to FIG3, 6, 7, 9, and 12 up to 18, seen in elevaticmal sectional view, moulded Position, feature one transition area each at every safety ring 3 and every tab 5 the position of which also determines the respective hinge or else film binge connection, particularly s i n c e sile 3c of at least one transition area of safety ring 3 closely fits by the inside to this hinge or else film binge connection 4 so this binge cr else film binge connection 4 is outvardly shifted across from inner surface 3b of skirt safety ring 3 and so the transition, area of tab 5 proceeds into this hinge or else film binge connection 4 The execution as to FIG. 20 does not feature, seen in elevational sectional view, moulded position, any transition area, on the contrary, here inner surface 3b of skirt of safetY ring 3 and inner surface of tab 5 closely fit on the inside to hinge or else film hinge connection 4 That applies also for the graphically not represented alternatives to FIG. 20. Preferred is seen in elevational. sectional view, moulded position at least one in particular straight running side 3c of at least one transition area of safety ring 3 which joins fitting on the inside to at least one hinge or else film hinge connection 4 at an angle of particularly .15* to 40* to outer surface 3a of skirt of safety ring 3 ,to be provided to defile from 1,4 below upwards aslent(cp. e. g. FIG. 3, 6, 7, 9, ad 12 to 18). It is preferred to have in moulded position seen in elevational sectional view, at least one in particular straight side 5a of at least one transition area of tab 5 or else of upper tab section 6 of at least one tab 5 which is joined closely fitting on the inside and/ or outside to at least one hinge or e7.se film hinge connection 4 running aslant from above downwards at an angle of particularly 15" to to the outer and/or inner surface of at least one tab 5 or else to -uter surface of upper tab section 6a and/or inner surface of up- Io per tab section 6b (cp. e. g. FIG. 3, 6, 7 and 12 to 18 with regard to a side 5a downwardly joined on the outside, seen in elevational sectional view, moulded position, to hinge or else film hinge connection 4 At least one tab 5 se-en in moulded position, my be subdivided, as for relative heigth, into several tab sections. Preferably at least one tab 5 is subdivided into two tab sections, an upper tab section 6 and a lower tab section 7 (cp. e. g. FIG. 1, and 3 to 19). Preferably there is in moulded position, seen in elevational sectional view, at least one tab section of at least one tab 5 proceeding downwardly and outwardly opened out as against a higher up tab section of said tab 5. The division according to el evational height of every two tab sections as a rule is supposed to be located in the range of their place of buckling. Such a buckling point my be sharpedged or to the inside or outside forred in a rounding according to a radius. When a tab 5 does not feature a buckling point or the like, so the division according to elevational height into a higher up tab section 6 and a lower tab section 7 is fictitiously assumed. Also 15 with a plurality of more than two tab sections naturally there are, seen in moulded position, an upper and a lower tab section in each tab 5 When a tab 5 features more than two tab sections, seen in moulded posi tion, upper tab section 6 turns into their upper tab section and lower tab section 7 turns into their lower tab section even if to simplify matters, in the expositions, I shall not go into any further detail then. Preferred is, in moulded position, seen in elevational sectional view, lower tab section 7 of at least one tab 5 be running from above downwards and outwardly opened out as against upper tab section 6 of this tab 5 (cp. FIG. 3, 6, 7, 9, mid 12 to 18). Such a spreading oflower tab section 7 opened out from tJmove downwards am outwards as against upper tab section 6 seen in moulded position in elevational sectional view, is of the moment to achieve great longitudinal body with inferior transversal body despite a thin maintained wall-thickness/substance, said longitudinal body corresponding to the arrangement of ribs (not illustrated here) transversal to circumferential direction of tanrper-proof closure 1 Moreover, in utilitarian positica, upper tab section 6 of respective tab 5 sticks out farther off inner surface of safety ring 3 as can clearly be see e. g. from FIG. 8. Thereby the circur.frential length of tab Tray bx kept smaller, and ribs (not illustrated here) transversal to circumferential direction of the tamper-proof closure I lacking side 5a nay defile in moulded position, seen in elevational sectional view, at a distinctly profitable obtuse angle to inner surface 6a of upper tab section 6 At the beginning already, moment of these aspects has been pointed out at some length, For upper tab 16 section 6 seen in moulded position, as well as for lower tab section. 7 ribs may be provided for further reinforcement running in circutnerential direction of the tanper-prr ,f closure 1 sane thing which is dealt with at a later stage. In moulded position, seen in ele- .ational sectional view, inner surface and/or outer surface of at least one tab section of at least one tab 5 nay bear axially, or however, to axial central line L L of tamper-proof closure 1 at an angle of O" to 180, particularly of V to 20, aslant from above downwards and outwards or inwards. In elevational sectional view, moulded position, the outer surface and/or inner surface of at least one tab section of at least one tab 5 may bear at an angle of O" to 180, particularly V to 20" to the inner surface and/or outer surface of said tab section aslant from above downwar.ds or fron below upwards and outwards or inwards. In moulded position seen in elevational sectional view, inner surface 6b of upper tab section 6 of at least one tab 5 departing from hinge or else film hinge connection 4 ay bear axially fran above downwards, or at an angle o of 0' to 180, particularly of V to running asL-mt from above downwards and outwards. In moulded position seen in elevational sectional view, inner surface 7b of lower tab section 7 of at least one tab may bear, departing from the lower distal end of upper tab section 6 of said tab 5 at an angle 0 of O" to 180, particularly of to 20, to axial central line L L of tamper-proof closure I aslant from above downwards and outwards. In moulded position seen in elevational sectional view, inner surface 7b of lower tab section 7 of at least one tab 5 may bear at an angle -of O to 180, particularly of 5" to 20, to inner surface 6b of upper tab t*) 17 section 6 of said tab 5 aslant fran above downwards and outwards.

The important thing in the preferred way of removing the plastic injection castings fron the injection-moud tool by stripping is that no inner sur.ace 6b of upper tab section 6 no inner surface 7b of lower tW) section 7 be jutting inwardly, as at first, the plastic casting must be removed from the core and only later is pressed by a central knock-out out of the stripper ring. In moulded positia, seen in elevational sectional view, outer surface 7a of at least one lower tab section 7 may bear at an angle of 0 to 180, particularly of 1' to 10" to inner surface 7b of said lower tab section 7 aslant fran above downwards and outwards. Outer surface and inner surface of at least one tab section of at least one tab 5 in moulded position seen in elevational sectional view, may extend parallel to each other.

Outer surface 6a and inner surface 6b of at least one upper tab section 6 in moulded position, seen in elevational sectional view, may extend parallel to each other (cp. e. g. FIG. 3, 6, 7, 9, and 12 to 15). Outer surface 7a and inner surface 7b of at least one lower tab section 7 in moulded position, seen in elevational sectional view, may extend parallel to each other (cp. e. g. FIG. 3, 6, 7, 9, 12, 13, and 16). In moulded position, seen in elevational sectional view, at least one tab section of at least one tab 5 may be enloodied, departing fran a point that is shifted across fran low distal end of said tab section in a pitch upward or downward, or from the lower or upper end of said tab section, as tapering or broadening over partly or totally its relative height fron below upwards or fran above downwards. In moulded position, seen in elevational sectional view, low- 18 er tab section 7 of at least one tab 5 may be embodied from above downwards w'ith a gradually increasing wall-thickness/substance (cp.

e. g. FIG. 14, 15, 17, and 18). sui~ch an increased wall-thickness/sub stance, in moulded position, seen in elevational sectional view, formed fran above downwardly in lower tab section 7 enables strengthening it. Designing the wall-thickness/substance gradually increased, in moulded position, seen in elevational sectional view, fromn above downwardly in lower tab section 7 is inportant for the stripping procedute in respect of a preferred way of reoving the plastic casting fran the injection-truld tool.

During the expositions, terns are used like "fromi ahove downwards/ downwardly", "from below up'wards upwardly", "upper", "olower"f, "upward(s)", "downwrd(s)'V"at the. 1.eve1 levational height, "relative height", etc.; these terms refer to mi elevational position, i. e. upright position of tanper-proof clcx-ure 1 as demonstrated by drawing. "Eixpoitions" are called the descriptions and claims. The container, as known, is not illustrated. The 'miulded position"' of tanrperproof closure 1 is that position of tmaper-proof closure before tabs 5 are hilnged inwards, in which position tanper-proof closure 1. is got out of the injection-mauld tool. "Side edgeP 5b of tab 5 are called the two side.brims of the respective tab 5 The "fracture points" 16 are bridges so frail that they will break during the upward lifting when unscrewing talnper-proof closure 1 Fracture po3ints 16 may be point-like formed or as film webs. The "connection points" 11 are bridges of a kind that are so strong formred that with the upward lifting of tmv'er-proof closure I when being un- 19 screwed, they will not break. Connection points 17 may be point-like embodied or as film webs. For the executions, the adjective "respective" is meant in the meaning of "concerned", "al located". 'Partial circumference" means a portion of the circumference of tamper-proof closure 1 Where in the expositions is mentioned a transfer ring of container neck, that way as well be sae other kind of a suitable annular projection, as far as this is not excluded through the context, even if to sirplify matters this has not explicitly been pointed out in more detail then. As "subsequent/later opening" is termed the opening procedure of tamper-proof closure 1 after splitting of fracture points 16 In case there are particulars about angles, and if that face, to which the indicated angle, seen in elevational sectional view, is relating, at least in sections runs crooked or angled, then in order to determine the angle indicated, an imaginary line is laid running, seen in elevational sectional view, through the upper and the lower farthest point of that face. In case that because of an appropriate curvature the transition, seen in elevational sectional view, between two surfaces is not recognizable, then the point which is the lower one according to elevational sectional view is supposed to be the transi.ion. "Outer surface" of a tab 3 is termed the, seen in moulded position, outer surface of s'id tab 5 and "inner surface" is termed the -seen in moulded position inner surface of that tab.

In case the elevational position of tanager-proof closure 1 is at the same tire the xmuded position, the utilitarian positimi, or the position of tmqper-proof closure 1 after being screwed onto container neck, then if necessary, this is especially noted in the expositions.

20 In moulded position, seen in elevational sectional view, lower tab section 7 of at least one tab 5 may be enbodied, departing from a point shiftd across from the upper end of said tab section in a ',itch downward, or particularly departing from its upper end to extend over partially or totally its relative height with a downwardly growing wall-thickness/substance (cp. e. g. FIG. 14, 15, 17, and 18 with regard to a lower tab section 7 that in moulded position, seen in elevational sectional view, is embodied from its upper end over its total relative height with a growing wall-thickness/substance). In doing so, the wall-thickness/substance in the range of the place of buckling or the like, as a good opportunity, is not thickened. In moulded position, seen in elevational sectional view, the relative height of lower tab section 7 may be equal to the relative height or snaller than the relative height, or particularly greater than the relative height of upper tab section 6 The transition area between upper tab section 6 and lower tab section 7 of at least one tab 5 in the position of their being inwardly swivelled (utilitarian position) and located in their middle in circumferential direction of tamper-proof closure 1 may be positioned in a pitch shifted upwards or downwards as against the transition area between side 3c of at least one transition area of safety ring 3 and the inner surface of skirt of safety ring 3 or may in particular be positioned at the same level of elevational height of the transition area between side 3c of at least one transition area of safety ring 3 and inner surface 3b of skirt of safety ring 3 As for elevational height, the two transition areas in the inwardly 21 swivelled position of respective tab are anyway not running congruent itHin the entire partial circumference, when, in monulded position, seen in elevatinal sectional view, the two transition areas preferably extend in their elevational height without crook bearing over their partial circumference; but in utilitarian position, the transition area of respective tab 5 is situated in circumferential direction of tanper-proof closure 1 at the distal ends of said tab at a lower level than in its medium range. In moulded position, seen in elevatinal sectional view, at least one tab 5 or else upper tab section 6 of at least one tab 5 may extend departing froman hinge or else film hinge connection 4 from above axially downwards (cp. e. g.

FIG. 9).

In moulded position, seen in elevational sectional view, at least one tab 5 or else. upper tab section 6 of at least one tab 5 may 'ear departing from ninge or else film hinge connmection 4 from above downwards, outwardly opened out at an angle to axial central line L L of tarper-proof closure 1 (cp. e. g. FIG. 3, 6, 7, and 12 to 18).

In moulded position, seen in elevational sectional view, lower tab section 7 may extend as a prolongation to and at the same angle as upper tab section 6 (not illustrated here). Preferable are at least one tab 5 and/or at least one tab section and/or at least one tab section 8 and/or at least one upper tab section 6 and/or at least one lower tab section 7 being resilient or else flexible formed at least per section and/or at least in sections, as for the relative height with regard to its or else their partial circumference. That is a matter of great inmport for the purpose of tabs, in particular for their inward swivelling (utilitarian position).

22 In the inner surface and/or the outer surface of at least one tab section of at least one tab 5 at least one reinforcing rib or else mne reinforcing rib apiece nwy be designed to bear in circtmtferential direction of tanrper-proof closure 1 over partly the partial circumference of said tab section, in particular with same gaps toward side edges Sb of tab 5 or to bear over its entire partial circumnference and, in moulded position, seen in elevational sectional view, over a part of its relative height departing from its lower end~ and shifted upwaards, or departing f roun its lower or upper end and shifted downwards, or to rini across the entire relative height thereof. in inner Surface 6b and/or particularly in outer surface 6a of imoulded position of upper tab section 6 of at least one tab 5 at least one or else one upper reinforcing rib 11 apiece way be designed that is bearing in circumferential direction of tanper-prcoof closure 1 over partially the partial circumference thereof, in particular showing equal distances to side edges SL thereof, or bearing in particular over the entire partial circxnference thereof. In Mo~ulded position, seen in elevational sectional view, at least one upper reinforcing rib 11, m~y bear departing f run a point situated in a pitch shifted upwards as against the transition area between upper tab section 6 and lower tab section 7 of at least one tab 5 or in particular departing fran, the transition area between upper tab section 6 and lower tab section 7 of at least one tab 5 over partially the relative height or particularly the entire relative height of this upper tab section 6 fram below upwards (cp. e. g. FIG. 16 to 18 regarding upper reinforcing rib 11 which is bearing in imulded position, seen 23 in elevational sectional view, over the total relative height of upper tab section 6 Thereby also the wall-thickness/substance in the range of the place of buckling or the like, to advantage, is not thickened, nevertheless facilitating the stiffening of upper tab section 6 in moulded position. At least one reinforcing rib, and/or at least one upper reinforcing rib 1 and/or at least one lower reinforcing rib 12 may feature any geometrical shape, consequently for instance in moulded position, seen in elevational sectional view, the shape of a trapezoid or the like, or particularly at least basically the shape of a triangle or similar (cp. e. g. FIG. 16 to 18 as for a triangle shape, in moulded position, seen in elevational sectional v ew, to an upper reinforcing rib 11 and FIG. 15, 17, and 18 regarding a lower reinforcing rib 12 Preferably side 5a of at least one transition area of tab 5 is shorter than side la and is efbodied at an obtuser angle to inner surface *6b than side 11a In doing so inside diameter between upper tab sections 6 in utilitarian position is kept small, and upper tab sections 6 do not obstruct the tanper-proof closure 1 being flexed over the transfer ring of container neck, all the more so since anyway but lower tab sections 7 moulded position, are significant to produce a resilient effect in utilitarian position. Furthermore, gradually thickening the wall-thickness/substance of upper reinforcing rib 3i seen in elevational sectional view, moulded position, fran above downward, and also of lower reinforcing rib 12 from below upward is accaplished by those triangle shapes, the wall-thick-hess/substance so enlarged having d favourable bearing on the stripping with regard to a preferred remov- 24 ing f ran the mo~uld of the plastic mould castings out of the injectionnxuld tool. Lower reinforcing rib 12 moulded position, is meant mainly to serve to widen the wall -thuickness/substance, seen in elevat i.onal sectional view, mul~Jded Position, of the associate locking f lank 10 to prevent thereby respective tab 5 f rau buckling, and thus to warrant secure engaging and contracting below transfer ring of container neck. In umulded position, at least one reinforcing rib and/ or at least one upper reinforcing rib 11 and/or at least one lower reinforcing rib 12 my feature any nixr of sides yon choose.

Preferred is at least one upper reinforcing rib 11 in moulded position, to feature two sides, an upper side 5a and a lower side 131 (cp. e. g. FIG. 16 to 18), and at least one lower reinforcing rib 12 to feature a side 12a (cp. e. g. FIG. 15, 17, and 18). In mroulded Position, seen ~in elevational sectional view, at least one side of at least one reinforcing rib may bear aslant fran below upwards or f ran above downwards and outwards or inwards at an angle of 0* to 180% particularly of V to 20* to the outer or inner surface of at least one tab section of at least one tab 5 In moulded position, seen in elevational sectional view, lower side 31.b of at least one upper reinforcing rib 11 thuat is arranged in inner surface 6b of upper tab section 6 of at least one tab 5 way run aslant from below upwards and inwards at an angle of 0* to 180% particularly of V to to outer surface 6a of this upper tab section 6 in moulded position, seen in elevational sectional view, lower side, Mi of at least one upper reinforcing rib 11 embodied in outer surface 6a of upper tab section 6 of at least one tab 5 may 25 run aslant from below upwards and outwards at an angle of O0 to 180', particularly of i' to 20' to upper side 5a of that upper reinforcing rib 11 In moulded position, seen in elevational sectional view, lower side Ub of at least one upper reinforcing rib 11 arranged in outer surface 6a of upper tab section 6 of at least one tab 5 may run aslant from below upwards and inwards at an angle of O' to 180*, particularly of 1' to 10' to inner surface 6b of that upper tab section 6 In moulded position, seen in elevational sectional view, lower side 11b of at least one upper reinforcing rib 11 spaced in outer surface 6a of upper tab section 6 of at least one tab 5 may run Rslant from above downwards and outwards at an angle of O' to 180', particularly of I' to 20' to upper side 5a of that upper reinforcing rib 11 In moulded position, seen in elevational sectional view, lower side Ub of at least one upper reinforcing rib 11 may be running parallel with axial central line L L of tanmer-proof closure 1 wherein preferably upper reinforcing 'ib 11 is laid out in outer surface 6a of upper tab section 6 of respective tab 5 These possible combinations in designing the course of the respective upper side 11a of upper reinforcing rib 11 in moulded position, seen in elevational sectional view, either running froa above downwards and outwards or in particular parallel with vertical axis L L of tanper-proof closure 1 are regarded as significant, as the electrode necessary for manufacturing the tab-shaping steel rings of the plastic moulding injection tool, can axial-centrically be put in into the steel rings during the erosion process, without need of rnak- 26 ing partial revolutions for electro-erosion arches, thus reducing the costs of the erosion process to a fraction of the otherwise incurring costs. Besides such a course, seen in elevational sectional view, moulded position, of lower side lMb operates edvantageously on the stripping procedure upon removing the plastic castings from the injectionmould tool.

In moulded position, seen in elevational sectional view, lower side 11b of at least one upper reinforcing rib 1 nay defile at an angle of 0* to 180, particularly of V to 15" to axial central line L L of twrper-proof closure 1 aslant fran below upwards and outwards or inwards, according as this upper reinforcing rib 1 is disposed for in outer surface 6a of upper tab section 6 or inner surface 6b In nmulded position, seen in elevational sectional view, the relative height of upper side 5a of at least one upper reinforcing rib 11 may be equal to the relative height, or larger than or particularly smaller than the relative height of lower side llb of that upper reinforcing rib 11 The preferred relative height, seen in elevational sectional view, moulded position, of upper side Sa is smaller than the relative height of -lower side lb Outer surface and/or inner surface of at least one tab section and/or outer surface 6a and/or inner surface 6b of upper tab section 6 and/or outer surface 7a and/or inner surface 7b of lowei tab section 7 and/or at least one side of at least one reinforcing rib and/ or upper side 5a and/or lower side llb of at least one upper reinforcing rib 11 and/or side 12a of at least one lower reinforcing rib 12 may feature any suitable gectrical shape, xtay consequently 27 be formed for instance, in moulded position, seen in elevational sectional view, at least in sections concave or convex, circle-segmental or similar to circle segments or the like, or ellipse-segmental, or similar to ellipse segments or the like, or parabola-segmental or the like, or with sine curve brim segments or similar to that, or the like, or hyperbola-segmental or similar to hyperbola segments or the like, or egg-shape-segmental or similar to egg-shaped segments or the like, herewith being arched or showing at least in sections a straight course, in particular straight formed at all.

The respective transition between every two faces may be designed sharp-edged, steady, or under a radius. In inner surface 7b and/or in particular outer surface 7a of lower tab section 7 according to moulded position of at least one tab 5 at least one or else one lower reinforcing rib 12 apiece nay be provided, in circumferential direction of tznper-proof closure 1 to bear over partly the partial circumference thereof with particularly equal gaps to side edges of tab 5 thereof, or in particular to bear over totally the partial circumference thereof. In moulded position, seen in elevational sectional view, at least one lower reinforcing rib 12 may bear departing.

from a point situated in a pitch downwardly shifted as against lower tab section 7 of at least one tab 5 over partly the remaining relative height or particularly over totally the remaining relative height of that lower tab section 7 fran above downwards (cp. e. g, FIG. 15, 17, and 18 with regard to a lower reinforcing rib 12 which is extending fron the upper end of lower tab section 7 from above downwardly over the entire remaining relative height thereof). In moulded position, at least one lower reinforcing rib 12 may be embodied 28 to have the wall-thickness/substance in particular gradually widening from above in the downward course of said rib (cp. e. g. FIG. 15, 17, and 18).

A wall-thickness/substance, in moulded position, seen in elevaticnal sectional view, that is increased in the co-se from above donward of said rib, is of great moment for the stripping process as to a preferred vay of removing the plastic castings from the injection-mould tool. In moulded position, seen in elevational sectional view, side 12a of at least one lower reinforcing rib 12 arranged in outer surface 7a of lower tab section 7 of at least one tab 5 may defile at an angle of 0' to 180", particularly of 10" to 40" to inner surface 7b of that lower tab section 7 aslant from above downwards and outwards. In moulded position, seen in elevational sectional view, side 12a of lower reinforcing rib 12 of at least one lower reinforcing rib 12 aranged in inner surface 7b of lower tab section 7 of at least one tab 5 may run at an angle of 0* to 180, particularly of 10" to 40' to outer surface 7a of that lower tab section 7 aslant fron above downwards and inwards. In moulded position, at least one or else one lower reinforcing rib 12 apiece may be disposed in lower tab section 7 of at least one tab 5 at the low distal end thereof (cp. e. g. FIG. 15, 17, 18, and 19). In moulded position, seen in elevational sectional view, the relative height of side 12a of at least one lower reinforcing rib 12 my be equal to or larger than the relative height, or in particular smaller than the relative height of the above located outer surface 7a and/or inner surface 7b of lower tab section 7 of at least one tab 5 (cp. e. g.

FIG. 15, 17, 18, and 19 with regard to a lower reinforcing rib 12 of A, 2' 29 a smaller relative, height than the reiative height of the above located outer surface 7a especialli, since, in moulded position, seen in elevational sectional view, lower reinforcing rib 12 by preference is to serve for adding of material to the wall-thickness/substance to locking flank 10 1 At least one tab 5 in inwardly swivelled position (utilitarian position), with its inner surface, may be propped against the safety ring 3 (cp e. g. FIG. 21) and/or against screw cap 2 (not illustrated here). At least one tab 5 may be wubdivided into one tab section 8 and at least one tab section 9 which is cut out from the latter by slits and is resilient or else flexible formed e. g. FIG. and 21). In moulded position, at least one tab 5 may be subdivided into one tab section and at least one tab section 9 which resilient or else flexible formed downwardly exceeds that tab section (not illustrated here). In moulded position, at least one tab section 8 may downwardly exceed at least one tab section 9 allocated to said tab section 8 (cp. e. g. FIG. 20), this exceeding area of said tab section 8 in inwardly swivelled position (utilitarian position) with tanPer-proof closure 1 screwed onto container neck getting serriedly locked between container neck and inner surface 3b of skitt of safety ring 3 and/or screw cap 2 The executions of tamper-proof closure 1 according to FIG. 20, and 21 fundamentally differ fron the other executions of tawper-proof closure 1 for the rest of the executions do not feature any tab sections 8 as get stuck between safety ring 3 and transfer ring of container neck, but show tabs 5 or else tab sections cushioned at safety ring 3 Therefore the executions of tanper-proof closure 1 following FIG. :V

.I-

30 21 suit to containers, where safety ring 3 ailer splitting remains with the container neck and not with screw cap 2 .If safety ring 3 here would be divided into individual sections (sections of safety ring), then tabs 5 would again swing out downwardly, i. e.

concerning the executions according to FIG. 20, 21, and their variants as described, there is a restricted field of application. In moulded position, seen in elevational sectional view, at least one tab section 9 may bear at an angle of 0* to 180% particularly of V to to the tab section allocated, thereto or else to tab section 8 from above downwards and outwardly opened out. The executions according to PIG. 20, 21 and their variants produce the effect that respective tab section 9 is urged, because of its resilient and flexible entodixrent to completely lean against inner surface 3b of skirt of safety ring 3 when flexed ov-,:r transfer ring of container neck, without expanding safety ring 3 At least one locking flank 10 may be centrically shifted for a part of its partial circumference in circmferential direction of tanper--proof closure 1 or be shifted fromi at least one distal end toward the middle, or in particular be cut on the slant in the range of at least one distal end, seen in elevational seetional view, mulded position, from the inside outwards and from above downwards and/or particularly from the outside inwards and from above downwards (cp. e. relating to the circumnferential direction of tamper-proof closure 1 FIG. 5 concerning a centrical disposition, and e. g. FIG. 4 concerning the disposition in the range of a distal end, and relating to moulded position, seen in elevational sectional view, e. g. FIG. 6, and 9 concerning the taper ratio of inwardly and f ran above downwardly cut-on-siant items). "Fran the outside to the in- 31 side", that means, in moulded position, seen in elevational sectional view: from outer surface toward inner surface. Where for instance in outer surface 7a of lower tab section 7 a lower reinforcing rib 12 is placed at its distal end, seen in moulded position, there the expression "fran the outside inwards" means, in nulded position, seen in elevational sectional view: from side 12a of that lower reinforcing rib 12 toward inner surface 7b of this lower tab section 7 Accordingly "fram the inside outwards" means, in moulded position, seen in elevational sectional view: fran inner surface toward outer surface. That correspondingly applies for outer surface 13a and inner surface 13b of at least one projection 13 too. "Cut on the slant cuneiform will say, as a rule, that in moulded position, seen in elevational sectional view, the outer surface is sloping or running downward aslant fran above toward the inner surface, or the inner surface is sloping or running downward aslant form above toward the outer surface, but may also mean the outer surface as well as the inner surface passing aslant from above downward toward each other.

That applies accordingly also for outer surface 13a and inner surface 13b of at least one projection 13 The cut-on-slant disposition as seen in elevational sectional view, moulded position, does not exclude an at least sectionwise bent of the concerning surface g.

outer surface .13a and/or inner surface 13b of at least one projection 13 To simrplify matters, I decide to define as cut-on-slant/ tapering disposition, seen in elevational sectional view, moulded position, of the respective locking flank 10 of tab 5 though strictly speaking, it is the low distal end of the allocated tab 5 or else of lower tab section 7 allocated to it, that is cut on the slent. At 32 least one rib 14 may be placed in circumferential direction of tamper-proof closure 1 centrically or shifted from at least one distal end toward the middle, or placed in the range of at least one distal end of at least one tab 5 or else tab section 7 of at least one tab 5 and/or, in moulded position, seen in elevational sectional view, in particular cut on the slant at least at its low distal end from the inside outward and from above downward and/or particularly from the outside inward and from above downward. Decisive for the position of the cut-on-slant sections and ribs, seen in elevational sectional view, moulded position, is the respective execution of tanper-proof closure 1 As for position and significance, ocrpare with the later executions In respect of projections 13 At least one rib 14 in moulded position, seen in elevational sectional view, may bear downwards, exceeding the low distal end of at least one tab 5 or else the low distal end of lower tab section 7 of at least one tab (cp. e. g. FIG. In moulded position, seen in elevational sectional view, upper tab section 6 and/or lower tab section 7 of at least one tab 5 may pass from above downwards, outwardly opened out, and inner surface of at least one rib 14 placed in inner surface 6b of upper tab section 6 or of at least one rib 14 placed in inner surface 7b of lower tab section 7 of that tab 5 may be provided not to exceed inwardly an imaginary line A A or else to be runming up along that imaginary line A A (cp. e. g. FIG. 9 with regard to a rib 1.4 arranged in inner surface 7b It is inportant for the stripping procedure in respect of a preferred way of removing the plastic rcstings from the injection-mould tool, that respective rib 14 in moulded position, seen in elevational ,4 33 sectional view, does not exceed inwardly jutting out. On at least one or else on one locking flank 10 apiece may be provided at least one or else one projection 13 apiece, seen in elevational sectional view, moulded position, bearing from above downwards (cp. e. g. FIG. 10, 11, 12, and 17 as well as FIG. 19, a combination from FIG. 11, 17, and 18). In moulded position, seen in elevational sectional view, at least one proj-'ion 13 may be embodied as cut on the slant from above downwards and from the outside inwards (cp. e. g. FIG. 12, and 17). By that kind of cuneiform taper ratio, seen in elevational sectional view, moulded position, the respective tab 5 after fracture points 16 having broken, is prevented from possibly being forced below transfer ring of container neck in a posterior manoevre of unscrewing because, as seen in elevational sectional view, moulded position, the slanting arranged outer surface 13a of respective projection 13 slides past transfer ring of container neck thus hindering respective tab 5 to open out and extend downwardly into moulded position. In moulded position, seen in elevational sectional view, at least one projection 13 nay be shaped as running from the inside outwards and from above downwards and/or in particular from the outside inwards and frma above downwards particularly cut-on-slant to a point. In moulded position, seen in elevational sectional view, at least one projection 13 may be shaped as departing froa a point situated underneath the junction range between itself and locking flank 10 allocated to it, or in particular from this junction range between itself and locking flank 10 allocated to it, passing over partly the relative height or particularly the entire relative height from above downwards and fran the inside outwards and/or particularly 34from the outside inwards particularly cut-on-slant (cp. e. g. FIG. 12, and 17 concerning, in moulded position, seen in elevational sectional view, projection 13 etmbodied as cut-on-slant running from the junction range between itself and locking flank 10 over its entire relative height fromn above downwards and form the outside inwards). In circumferential direction of tanper-proof closure 1 at least one or else oe projection 13 apiece bearing over partly the partial circumference of at least one or else of xen locking flank 10 apiece may be laid out centrically on that locking flank 10 or shifted towards the middle across franom at least one distal end, or placed in the area of at least one distal end, Decisive for positionirg respective projection 13 in circumferential direction of tamper-proof closure 1 on locking flank 10 allocated to it is the appropriate execution of tanper-proof closure 1 In the executions according e. g. to FIG. 11, and 19, the connection points 17 are spaced-apart in circumferential direction of tanperproof closure 1 in such a way that the respective section of safety ring by preference splits open at the two distal ends thereof, whereas in the execution of tamper-proof closure 1 according to e. g. it is preferred having provided a connection point 17 in the area of that distal end in which projection 13 is arranged, and the splitting of the respective section of safety ring taking place at the opposite end. With such a disposition of projection 13 in circumferential direction of tamper-proof closure 1 at the distal end of a locking flank 10 said projection indeed is not only required to inpede that associate tab 5 after fracture points having broken, in a pot,,A t K2- 'I.

t 'Vv' (1 35 sterior manoeuvre of unscrewing is easily forced below transfer ring of container neck, but is also necessary, with fracture points 16 not yet broken in the first unscrewing procedure, for running against and sliding up onto transfer ring of container neck. That applies correspondingly for the execution according to FIG. 5, too. Preferably outer surface 13a, and/or inner surface 13b of at least one projection 13 seen in elevational sectional view, moulded position, has a straight surficial embodiment (cp. e. g. FIG 12, and 17). The preferred inner surface 13b of at least one projection 13 in particular extending stmight, seen in elevational sectional view, moulded position, is laid out axially (cp. e. g. FIG. 17).

That serves to inprove the plastic moulding injection tool, as its supplen-entary steel rings which have the indentations for making projections 13 feature cylindrical bores, and therefo,:e can be more easily adapted than conic surfaces. In n- ulded position, seen in elevational sectional view, inner surface 13b of at least one projection 13 however, may also show a surficial embodiment in prolongation of and at the same angle as the inner surface of tab 5 associate t that projection 13, or else as inner surface 7b of lower tab section 7 of tab 5 associate to that projection 13 (cp. e.g. FIC. 12). The preferred section or else sections of at least one locking flank that are spaced in circumferential direction of tarer-proof closure 1 beside at least one projection 13 seen in elevational sectional view, moulded position, are running straight and preferably at right angles to axial central line L L of tamper-proof closure 1 (cp. e. g. FIG. 14, 15, and 18). The preferred sections of associate locking flank 10 spaced in circumferential direction of tamper-proof 36 closure 1 beside a projection 13 seen in elevational sectional view, moulded position, are designed to run straight even then and at right angles to axial central line L L of tanper-proof closure 1 when respective tab 5 or else lower tab section 7 of respective tab 5 are outwardly opened out. That sinplifies the injection-mould tool, because then, its steel rings that shape safety ring 3 and tabs 5 nust only be face-grinded which furthermore makes elevational adjustment of the individual steel rings in their ratio versus the core less difficult, is time-saving and hence cost-saying. In utilitarian position, as a desirable effect, seen in elevational sectional view, prevails a slight tapering of that locking flank 10 of tab 5 toward the outer surface and hence an inproved engaging and gripping below transfer ring of container neck. In moulded position, seen in elevational sectional view, the wall-thickness/ substance of at least one projection 13 within the junction range with the associate locking flank 10 may be bigger or smaller than the wall-thickness/substance of that locking flank 10 (not illustrated here). Preferably the wall-thickness/substance of at least one projection 13 in the junction range with the associate locking flank 10 of tab 5 equals the substance/wall-thickness of that locking flank 10 (cp. e. g. FIG. 12, and 17). In moulded position, at least one rib (not illustrated here) or at least one rib 14 laid out in the cater surface and or inner surface of at least one tab or else in outer surface 7a and/or in inner surface 7b of lower tab section 7 of at least one tab 5 may extend into respective projection 13 or terminate above this projection 13 In circumferential direction of tanper-proof closure 1 at least one section of h" 37 the locking flank 10 positioned close to at least one other section of locking flank 10 that, in moulded position, seen in elevational sectional view, is in particular cut-on-slant formed, and/or positioned close to at least one rib 14, and/or close to at least one projection 13 may be downwardly depending, seen in elevational sectional view, moulded position, passing froman above as cut an the slant froman the outside to the inside and/or particularly from the inside to the outside, and/or may be embodied running in particular at a right angle to axial central line L L of tamper-proof closure 1 (cp. e. g.

FIG. 7, and 13). In circumferential direction of tarrper-proof closure 1 at least one locking flank 10 bearing over at least partly its partial circumference or else outer surface and/or inner surface of at least one cut-on-slant section of at least one locking flank 10 seen in elevational sectional view, moulded position, and/ or outer surface and/or inner surface of at least one particularly cut-on-slant formed rib 14 seen in elevational sectional view, moulded position, and/ or outer surface 13a and/or inner surface 13b seen in elevational sectional view, moulded position, of at least one particularly cut-on-slant projection 13 these may feature any suitable geometrical shape, that means being bent, seen in elevational sectional view, moulded position, for instance at least in sections concave or convex, circle-segmental or similar, or ellipsesegmental or similar, or parabola-segmental or similar, or in a sine curve or similarly, or hyperbola-segmental or similar, or oval-segmental or similar, or at least in sections showing a straight surficial embodiment, in particular being embodied straight. The respective transition between two surfaces may be sharp-edged, steady or shaped under 38 a radius. In circumferential direction of tarper-proof closure 1 and/or in moulded position, seen in elevational sectional view, the particularly cut-on-slant tapering forms of at least one section or else of at least one in particular cut-on-the slant section 10a of at least one locking flank 10 and/ or of at least one rib 14 and/ or of at least one projection 13 may in particular smoothly interfuse (cp. e. g. FIG. 9 with regard to steady transition, seen in elevational sectional view, moulded position, of a cut on-the-slant section 10a of locking flank 10 and a cuneiform taper rib 14 In the screwed-up position of taiper-proof closure 1 on container neck, at least one section of at least one locking flank 10 and/ or at least one particularly cut on-the-slant section of at least one locking flank 10 seen in elevational sectional view, moulded position, and/or at least one rib 14 and/or at least one projection 13 may engage and contract below transfer ring of container neck or be arranged at particularly little distance from said transfer ring. The in particular cut-on-slant sections 10a seen in elevational sectional view, moulded position, and the ribs 14 as well as projections 13 are not destined to jam between transfer ring and inner surface 3b of skirt of safety ring 3 but are meant to slide past transfer ring of container neck on posterior opening of the closure after fracture points 16 splitting, without allowing to be pressed below said transfer ring, thus impeding tabs 5 from downwardly swinging back into moulded position. In moulded position, at least two different sections of at least one locking flank 10 may be separated from one another by slots in particular short and in particular running transversal to circumferential direction of tanper-proof clo- 39 sure 1 (not illustrated here). In moulded position, at least one slot (not illustrated here) and/or at least one groove (not illustrated here) may be provided running transversal to circumferential direction of tamper-proof closure 1 bearing from below upward into lower tab section 7 and/or into upper tab section 6 and in circumferential direction of tamper-proof closure 1 being in particular centrically positioned (not illustrated here). In case such a slot (not illustrated here) in moulded position is for instance bearing over the entire relative height of lower tab section 7 so this one will be subdivided into two lower tab sections 7 Through this forementioned possibility transversal body of respective tab 5 is reduced, on the other hand, however, longitudinal body is not about enhanced. To simplify matters, "n such a case of e. g. subdividing slots (not illustrated here), regarding tab 5 an upper tab section 6 and a lower tab section 7 are determined. In moulded position, seen in elevational sectional view, the relative height of at least one tab 5 and/or the relative height of at least one tab 5 plus at least one rib 14 and/ or projection 13 arranged in said tab, may be greater or lesser than the relative height of safety ring 3 Preferably the relative height of at least one tab 5 in elevational sectional view, moulded position, and/or the relative height of at least one tab 5 plus at least one rib 14 and/or projection 13 equal the relative height of safety ring 3 In moulded position, ribs (not illustrated here) running in particular transversal to circumferential direction of tiaper-proof closure 1 may be particularly uniformly configured and/or regularly spaced-apart in the outer surface and/or inner surface of at i..

40 least one tab 5 or else in outer surface 7a and/or inner surface 7b of lower tab section 7 of at least one tab 5 and/or of at least one tab section 8 (not Uilustrated here).

The expositions mantion reinforcing ribs running in circumrferential direction of tanper-proof closure 1 without indicating any reference number, and reinforcing ribs transversal to circumferential direction of tanper-proof closure 1 also without reference nizrber. For discrimination, the ribs running tr~sversal to circumferential direction. of tanper-proof closure 1 have got a note in parentheses: (not illustrated here). When "sides" are mentioned without indication of reference ntubers, then the sides of reinforcing ribs are concerned that are running in circuzmferential direction of taqper-proof closure 1 Safety ring 3 or else at least one section of safety ring 3 may be connected via at least one connection point 17 and/or via at least one fracture point 16 with screw cap 2 (cp. e. g. FIG. 1, 2, and 19, regarding two connection points 17 The safety ring may feature at least one slot 15 particularly running axial together with at least one or else one fracture p>oint 16 apiece bearing over the total relative height of said safety ring (not illustrated here). Safety ring 3 on the other hand may as well feature at least one slot 15 running axial together with at least one or else one fracture point 16 apiece bearing over partly the relative height thereof (cp. e. g. FIG. That is ingenious for stripping in the preferred way of removal from the mo~uld of the plastic casting, when safety ring 3 has to be pushed out of the stripping ring by a central knockout, in order to save the thin-bridged fracture points 16 from crack- 41 ing upon removal f ran the inoul d. At least one each or else ow section of safety ring 3 may be connected with screw cap 2 in circumrf erential direction of ta;Tper-proof closure 1 via one connection point 17 apiece bearing over partly the partial circumference thereof, in particular showing equal distances to slots 15 which bound said section of safety ring, in particular this connection point 17 featuring at its final ends a material thickenizi- per final end (not illustrated here).

One each or at least one section of safety ring 3 may7 be connected in circumnferential direction of tmper-proof closure I. with screw cap 2 via two slots 15 each, that bear over partly its partial circumference, showing in particular equal distances to the~ middle thereof and in particular equal distances also to slots 15 bounding said section of safety ring, in particular these tv.o connection points 17 featuring a mterial thickening at each of thleir final ends, that is at the ends that are facing slots 15 (cp. e. g. FIG. 19).

Such ma~terial stackings at connection point 17 ensure that the respective section of safety ring, after splitting open, juts out as little as ever possible, as the distal ends of safety ring 3 are held in their positions due to these material stackings. Where the disclosure of the inventions deals with a slot 15 there of course also its fracture point 16 or its fracture points 16 respectively', are mreant, as far as these are still unviolate, even if to siirlify matters, no more details are given. in mo~ulded position, locking flank 10 of at least one tab 5 m~y be concavely dented at least in sections in circumnferential direction of tairper-proof closure 1 fran below upwards (not illustrated here). Preferably locking flank 10 of 42at least one tab 5 moulded position, is configured as straight running in circumferential direction of tnper-proof closure 1 (cp.

e. g. FIG. 1, 3, 4, 5, 10, 11, and 19). The effect of a straight-running locking flank 10 tab 5 moulded position, in circumferential direction of tanper-proof closure 1 is that in utilitarian position said locking flank 10 in the range of its final ends, keeps a distance in height fron the underside of the transfer ring of container neck, does not engage the ring in the range of its final ends, and thus by a manipulatory pressing towards inner surface 3b of skirt of safety ring 3 springs back into the initial position after release.

That way a maximum of security fran manipulating the tanper-proof closure can be scored. In moulded position, side edges 5b of at least one tab 5 may be configured as broadening or tapering frm below upwards (not illustrated here). The preferred side edges 5b of at least one tab 5 moulded position, are running transversal to circumferential direction of taimper-proof closure 1 and parallel to one another (cp e. g. FIG. 4, 5, 10, and 11). When in moulded position side edges 5b of a tab 5 are running transversal to circuTferential direction of tamper-proof closure I and parallel to one another, regarding the plastic moulding injection tool, the manufacture of those steel rings that embody the outlines of the tabs is considerably simplified, as the electrode can be put in into the steel rings axial-centrically without need of making partial revolutions for electro-erosion arches, which reduces the cost of manufacturing the steel rings quite considerably. At least one tab 5 may bear in circumferential direction of tanper-proof closure 1 over totally the partial 43 circumference of at least one section of safety ring, bounded by two slots 15 each (not illustated here). It is preferred at least one tab 5 shall extend in circumferential direction of tamper-proof closure 1 over partly the partial circumference keeping in particular equal distances fran slots 15 which bound said tab (cp. e. g. FIG.

4, 5, 10, and Whea in moulded position, side edges 5b of a tab 5 are running transversal to circumferential direction of tamperproof closure 1 and parallel to one another, then it is inportant this tab 5 be not extending over totally the partial circumference of its associate 'section of safety ring. As "section of safety ring" is designated a section, bounded by two slots 15 each, of the safety ring 3 In case, in the expositions there is a mentioning of safety ring 3 that can mean likewise, if not excluded by the context, respect:Ire section of safety ring or else respective sections of safety ring, even if to sinplify matters, there are not always any further details for the expositions.At least one hinge or else film hinge connection 4 my bear in circumferential direction of tamper-proof closure 1 over totally the partial circumference of at least one tab 5 (not illustrated here). Preferably at least one hinge or else film hinge connection 4 in circumferential direction of tamper-proof closure 1 is bearing over totall.y the partial circumference of at least one tab 5 (cp. e. g. FIG. 4, 5, 10, and In circumferential direction of tanper-proof closure 1 one each or else at least one comection point 17 my be arranged within a final end of one each or else at least one section of safety ring (section of safety ring 3 and one each or at least one in particular cut-on-slant section 10a of at least one locking flank 10 seen in elevational 44 sectional view, moulded position, and/or one each or at least one rib 14 and/or one each or at least one projection 13 may be arranged near to this final end of said tab 5 associate to this section of safety ring, or there may be disposed in circumferential direction of tamper-proof closure 1 one each or at least one connection point 17 centrically or in the middle region of one each or at least one section of safety ring bearing over partly the partial circumference thereof, or two each or at least two connection points 17 with in particular equal distances from the middle of one each or at least one section of safety ring may be laid out bearing over partly the partial circumference thereof, and one each or at least one in particular cut-an-slant section 10a of at least one locking flank 10 seen in elevational sectional view, moulded position, and/or one each or at least one rib 14 and/or one each or at least one projection 13 may be laid out centrically or in the middle region of the associate tab 5 of said section of safety ring (cp. e. g. FIG. 19). In an execution according to FIG. 19, a desired especially strong stiffening and deformation between respective safety ring 3 and associate tab 5 can be attained. At least one at least substantially rigid formed section of safety ring 3 provided without tab 5 may be connected in circumferential direction of tamper-proof closure 1 via at least one particularly strong formed connection point 17 bearing over partly its partial circumference or in particular over its entire partial circumference, with screw cap 2 by its side 3d which, seen in elevational sectional view, moulded position, is running aslant from the inside outwards and from above downwards, and/or may be connected with screw cap 2 via at least one connection bridge 18 in circumferential direction of 45 tamper-proof closure 1 in particular centrically arranged, and or be joint in the range of its final ends at least in sections with screw cap 2 by rather weak formed comnection points 17 and/or my feature slots (not illustrated here), in the range of its final ends (cp.

e. g. FIG. 1, 2, and 19). By that kind of sectims of safety ring without tabs 5 pimccess of safety ring sections splitting open is cut short by the fact that the safety ring sections without tabs 5 do not move along or hardly move along with the sections of safety ring upon first opening of the closure and that thus fracture point 16 will crack earlier. Where in the expositions there is a mentioning of a safety ring section, so this is a section of safety ring (section of safety ring 3 If a safety ring section without tabs 5 is meant, then the attribute "without tab" is especially added. Seen in elevational sectional view, moulded position, at least one fracture point 16 vrranged within at least one slot 15 ury bear fran below upwards, departing from a point shifted in a pitch upwards toward the level, of the transition area between side 3c of at least one transition area of safety ring and inner surface 3b of skirt of safety ring 3 over the entire reia~ning or partly the remaining relative height of that slot 15 (not illustrated here). Preferred is at least one fracture point 16 seen in elevational sectional view, moulded position, having been arranged within at least one slot 15 to bear from below upwards, departing fron a point situated at the level of the transition area which is located between side 3c of at least one transition area and inner surface 3b of skirt of safety ring, and to extend over totally the radnning relative height (cp.

e. g. FIG. 3) or over partly the remaining relative height.(not illus- 46 trated here). Thereby, regarding the injection-mould tool, a simplified technique of manufacturing the cores thereof is conditioned, because that way these cores altogether can be mnufactured as lathes works without brackets to be arranged in their outer surfaces. Otherwise the brackets on the outside ought to be made by erosion procedures, which would let go up the costs of cores enormously. At its inferior portion, screw cap 2 may feature a particularly annmular, particularly thin-walled collar outwardly expanded (not illustrated here), and said collar (not illustrated here), at least in the range of connection points 17 and/or fracture points 16 showing a wallthickness/substance in particular augmented by the thickness of the substance in the rest of screw cap 2 (not illustrated here). That sort of collar (not illustrated here) overlaps safety ring 3 or else the safety ring sections thereof that, eventually, are outwardly jutting in the cracked fit. Augmenting the wall-thickness/substance merely in the range of connection points 17 and/or fracture points 16 serves to save in material with the everywhere else thin-walled designed collar (not illustrated here). At least one fracture point 16 may be formed, seen in elevational sectional view, moulded position, as tapering from below upwards. That is funrc-tionally useful for the stripping procedure with regard to a preferred way of removal from the mould of this plastic injection-moulded casting, as the safety ring has to be pushed out of the stripper-ring by a central knock-out in order not to have got fracture points 16 cracked upon removal from the mould. At least one '-onnection point 17 and/or at least one fracture point 16 ay be spaced in circumferential direction of tamper-proof closure 1 centrically or departing franom a final end, shifted toward the middle or position- 47 ed in the range of at least one final end of at least one safety ring section (section of safety ring 3 (cp. in this context the .expositions with projections 13 in combination with connection points 17 Seen in elevational sectional view, moulded position, the in particular cut-on-slant tapering of at least one section of at least one locking flank 10 and/or of at least one section lOa of at least one locking flank 10 and/or of at least one rib 14 and/or of at least one projection 13 may be running at an angle of O' to 180', in parular of 10' to 45' to axial central lin.

Where in the expositions a (particularly) cut-onslant section of at least one locking flank 10 of tab 5 is mentioned, so this may mean a (particularly) cut-on-slant section of at least one locking flank 10 and/or a (particularly) cut-on-slant section 10a of at least one locking flank 10 unless one of these two possibilites is excluded by the context, even if to sirplify matters, this text does not go into further detail. The preferred tarrperproof closure 1 is integral formed in one piece. Preferred is that tanper-proof closure 1 be made oi suitable plastics, preferably of a relatively hard one in particular of medium-hard to hard plastics characterized by low elongation, particularly polypropylene or polyethylene or a material of similar physical properties.

All afortknentioned executions of tarper-proof closure 1 unless excluded by the context, can easily be cambined with one another at pleasure. The graphically demonstrated executions of the novel tanperproof closure 1 are not bound to the dimensions shown in the drawings, but can easily be manufactured according to any other required dimensions g. according to Gernan Industrial Standards Geometry and measurement of tanper-proof closure 1 or else of the portions of this tanper-proof closure can be realized at random, depending on exigency, in particular for the purpose of an improved adaptation to the containers. The variety of uses, which only need arrangements of constructional alterations, can be freely extended. The invention extends to all characteristics described in the disclosure which includes the figures, too. All features of the inv.ntion are regarded as essential items thereof falling within the spirit and scope of the 49 appended claims. The invention is not restricted to the exanples of execution represented by drawing and description.
