Description

The invention relates to a tamper-evident Closure arrangement one on one essentially tubular container mouth arranged, the Eehältsrmünd cap-like overlapping container closure, wherein on the free edge of the container closure directed towards the container, a predetermined breaking webs in one piece attached circlip is provided, which over one of the outer surface of the tubular container he mouth protruding annular bead is locked and a locking surface pointing away from the container mouth of the annular bead engages behind.

Tamper-evident security for closures, which are intended to ensure that contents cannot be removed unnoticed from containers closed with them or even exchanged for other inferior contents, are known in various configurations, in cases in which the container has a tubular mouth: aufveiser, ie the The container is designed as a bottle or tube, a locking ring is provided in ^one piece with the actual stopper or cap closure or a separate closure cap slipped over predetermined breaking webs, which tightly surrounds the outer wall of the container mouth and has a locking ring in the direction of the actual container mouth in front of the circlip lying circumferential annular bulge-tuff against the outer wall. Removal from the container mouth secured iiit. When opening the verse for the first time;

the predetermined breaking webs are therefore sheared off from the actual closure or the separate closure cap. Undamaged predetermined breaking webs thus guarantee that the container still contains the original filling quantity or no unauthorized exchange of the product has taken place. Have tamper evidence of this type have proven themselves and are therefore used on a large scale - especially in drug packs. so has been shown to be the case with plastic closures due to the elastic properties of the fasteners Plastics used with skillful manipulation is possible, the closure also under elastic expansion of the securing ring without shearing off the predetermined breaking webs over the securing bead. The procedure must be such that the force to remove the closure is exerted by pressure on the container-side free edge of the locking ring is exercised so that the predetermined breaking webs do not shear are claimed. Although so far no cases have become known in which this possibility is fraudulent Intentional has been exploited, there is a fundamental need to also use this possibility as a precaution to exclude.

The invention is therefore based on the object of a Tamper evident for plastic closures create that unauthorized opening of the lock in the specified way without breaking the predetermined breaking webs, i.e. a shearing off of the locking ring from the actual lock is definitely prevented.

Starting from a closure arrangement of the initially This object is achieved according to the invention solved that the outer wall of the tubular container mouth on the side facing away from the mouth of the Retaining ring behind-gripped annular bead with a annular circumferential wall section with opposite the normal outer diameter of the container mouth is provided with an enlarged diameter. The ring-shaped circumferential ¥ and section can be designed so that it either the free edge of the locking ring shields or he can stiffen the locking ring against deformation, so that in both cases one fraudulent manipulation is prevented.

If the free edge of the locking ring is to be shielded, the configuration is advantageous Further development of the invention made so that dc = r ring-shaped circumferential wall section into an approximately ·. distance corresponding to the width of the locking ring provided by the annular bead, from the outer wall of the tubular container mouth is radially projecting second circumferential annular bead, which the free The edge of the locking ring protrudes radially. The additional second annular bead on the outer wall of the container casing is therefore immediately in front of the free edge of the 3 security ring, which is therefore no longer considered a fraudulent Manipulation is accessible.

If alternatively a stiffening of the locking ring If the aim is to prevent deformation, the ring-shaped, circumferential end, see section on the circlip, is useful aligned arrangement within the locking ring and it has: '· an outer diameter., which is essentially equal to the clear inner diameter

The inner surface of the locking ring then lies on the surrounding area without a gap. running end of the tiand section and a deformation, e.g. by compressing the ring on opposite sides Sides in such a way that it slightly increases its diameter at right angles to the direction of compression and in this area the unlocking of the locking ring via the locking surface of the Ring bulge can be initiated is no longer possible.

It is advantageous if the mouth is turned away from the mouth free edge of the ring-shaped circumferential ¥ and from the cut aligned with the free edge of the locking ring so that the two free edges are in one plane. The locking ring can be arranged directly on the free edge of the cap-shaped container closure i be.

lying end 'the stopper part 14 is closed by a one-piece molded grip plate 18, the diameter of which is slightly larger than the outer diameter of the container opening around the front end of the container opening like a cap. At the lower free edge of the grip plate 18 a pull tab Zh is molded in one piece over a number of predetermined breaking webs 22 evenly distributed in the circumferential direction, which in turn carries a locking ring on its lower edge facing away from the handle plate - again via Sollliruchstege 22 - integrally molded locking ring.

The mouth 28 of the container 10, shown in FIG. 4 without the attached closure 12, has a circumferential annular bulge 32 on its outer wall at some distance below the front edge, the end face of an obliquely inclined annular surface 3 ^ »an adjoining cylindrical annular surface 36 and finally a radial annular surface 38 is limited. The locking ring 26 engages in the intended locking division (FIG. 2) with a molded on its inner side, to the outer enwandunj; of the container protruding circumferential ring surface 4θ behind the radial ring surface 38.

Pulling off from the container 10 secures. To open the closure 12, the tear-open tab 24 must be torn open, destroying the predetermined breaking webs 22 connecting it to the edge 20 of the grip plate 18 and the locking ring 26. It is clear that the lack of the pull tab after the closure 12 has been put on is a clear indication that the container has already been opened.

It has now been shown that the so far described When performing very specific manipulations, namely by exerting pressure on the lower free edge of the locking ring, at the same time Pressure on opposite areas of the locking ring open in some cases taking advantage of the possibility of elastic expansion of the locking ring can without breaking the predetermined breaking webs 22. This could be done from a container opened in this way Original filling material thus removed and replaced by falsified material and then the closure 12 again be put on. Although there is a risk of falsification of the contents of the container when using the described Manipulation per se can be described as low, because the locking ring - even when using the describe manipulation - in most cases it is destroyed and a falsification is evident as a result there is a requirement to train the lock so that it is no longer without Destruction of the breakaway webs holding the locking ring on the lock can be opened.

This annular bead 42 thus has a somewhat larger outer diameter of the locking ring 26 corresponding outer diameter, which means that the the lower edge of the locking ring 26 is no longer accessible. The desired additional security of the Closure 12 against unauthorized opening is thus guaranteed.

On the other hand, in order to facilitate the authorized opening of the closure, the pull tab 24 is designed as a handle at one end section 44 in that it is not connected to the securing ring 26 and the edge 20 of the grip plate 18 with predetermined breaking webs 22 over a certain length. The end section 44 is thus radially designed without exertion of force.

The tear tab facilitating closure is dispensed with, ie. the securing ring 2β is attached directly via predetermined breaking webs 22 to the lower edge of the section 20 of the G-ribbed plate T8 which overlaps the container mouth 28 like a cap. A more detailed description of the closure 12 'is therefore not required, especially since the same parts in the closure are provided with the same reference numerals in the drawing. In any case, it should be noted that to secure the closure 12 ^f against unauthorized opening, a second annular bead k-2 is provided on the outer wall of the container 10 at a distance from the first annular bead 32, which _{shields the lower t-} free edge of the locking ring 26.

In the embodiment shown in Figures 5 and 6, the arrangement of the securing ring 26 on the container closure 12 "takes place in the same ¥ ice as with the container closure 12, ie with the interposition of a tear-off tab 2h, the closure 12" itself, however, is designed as a more elastic closure cap A cylindrical receptacle 15 for a dry substance filling 17 is molded onto the end wall 18 'of the inner surface directed into the container and is held in the receptacle 15 by a moisture-permeable cardboard disc.

The container 10 'differs in the area of the container mouth 28 from the exemplary embodiments described above in that instead of a second annular bead 42 projecting radially above the securing ring 26 at a distance below the first annular bead 32, directly following the locking surface 38 of the first annular bead 32 in a the wall thickness of the container mouth is increased so that a circumferential wall section 42 'with a diameter that is slightly larger than the outer diameter of the container mouth 28 is formed.
