Definitions

  • the invention relates to a plastic closure for containers according to the preamble of claim 1 and a method for its production according to the preamble of claim 13; finally a device for producing a plastic closure with a guarantee ring with the features mentioned in the preamble of claim 16.
  • closures which are used to close any container.
  • the closures are provided with a guarantee ring, which should indicate the integrity of the sealed container. In a first attempt to open the guarantee ring is blown open, so that a consumer can easily see that the container is no longer originally sealed.
  • An exemplary embodiment of a closure is particularly preferred, which is characterized in that the position of the vertical incisions is selected as a function of the arrangement of the holding webs which hold the ring segments which arise when they burst open on the casing of the closure.
  • the vertical incisions are placed in an area of the guarantee ring that is deflected to the maximum extent when opened for the first time, both in the axial and in the radial direction. This ensures that the vertical cuts are blown open.
  • An embodiment of the closure in which the vertical incisions are bridged by webs is particularly preferred. This prevents the vertical incisions from being damaged after the closure has been manufactured during its storage or transport, but also when it is first put on, so that a consumer may be wrongly tampering with the container must close. This increases the security of the manipulation display even further.
  • the stated object is also achieved by a method for producing a plastic closure for containers, which has the features mentioned in claim 13.
  • This method is characterized in that, after making a horizontal cut, which creates a predetermined breaking line between the jacket and the guarantee area of the closure, the vertical incisions are cut depending on certain shape features of the closure or the guarantee area.
  • all material weaknesses in the area of the jacket of the guarantee area can be referred to as vertical incisions, even if there are only indentations or material weakening zones in the wall of the guarantee area that were not produced by a spraying process but by a cutting process.
  • the vertical incisions are actually made in the wall of finished closures by a subsequent cutting process, so that a defined material weakening is predetermined, which can be determined much more precisely than with a spraying process.
  • a defined material weakening is predetermined, which can be determined much more precisely than with a spraying process.
  • the holding forces in the area of the vertical incision can be predicted very precisely.
  • the precise positioning of the vertical incisions allows them to be cut there resulting explosive forces are precisely predetermined. In this way, tampering with the container can be excluded with a high degree of certainty without damaging the guarantee ring.
  • An embodiment of the method is particularly preferred in which the vertical incisions are cut into the wall of the guarantee area or the guarantee ring depending on the arrangement of the retaining webs.
  • the retaining bars remain intact when the container is opened for the first time.
  • the end regions of the ring segments held by the holding webs are deflected to a maximum in both the axial and radial directions, so that the greatest force of expansion occurs here. Because the vertical incisions are arranged here, it is very likely that they will be blown open.
  • the above-mentioned object is also achieved by the creation of a device which is used to produce a plastic closure with a guarantee ring for containers and which has the features mentioned in claim 16.
  • the device is characterized by a centering device, which detects and holds the closure positioned in dependence on its shape features, while the closure is brought into engagement with the cutting device.
  • a device is particularly preferred, the centering device of which has both an outer centering device and an inner centering device, the former sensing features on the outer surface and the latter sensing shape features on the inner surface of the closure.
  • the centering device of which has both an outer centering device and an inner centering device, the former sensing features on the outer surface and the latter sensing shape features on the inner surface of the closure.
  • a device is particularly preferred which is characterized in that the inner centering device is designed such that the inner contours of the closure can only be tapped after the outer contours have been detected.
  • the double scanning of shape features on the outside and then on the inside of the closure results in a particularly secure positioning of the closure before the vertical incisions are made in the wall of the guarantee ring.
  • the closure described below can be used universally. It is preferably used to close bottles which are provided with a screw thread on the outside below their mouth area and also have a projection which interacts with corresponding barbs on the inner surface of the guarantee ring.
  • Figure 1 shows a cross section through a closure 1 before it is applied to a container to be closed.
  • the closure has a closure mirror 3, which is followed by an all-round closed jacket 5.
  • a guarantee area designed here as a guarantee ring 9 is provided, which is connected to the rest of the jacket by means of tear-off webs 11, the tear-off webs spanning a predetermined breaking line 13, which is produced by a horizontally running cut made in the wall of the jacket 5 is.
  • the predetermined breaking line 13 is also spanned by a retaining web 15, which is practically over the the entire amount of the guarantee ring 9.
  • the tear-off webs 11 and the holding web 15 are formed by material strips applied to the inner surface of the jacket and running in the longitudinal direction of the closure. It can be seen from FIG. 1 that the tear-off webs are designed to be substantially narrower than the holding web, which is assigned to a ring segment which is created by the safety ring 9 being opened.
  • a seal 17 is provided on the underside of the closure mirror and is prevented from moving relative to the closure mirror 3 or the closure 1 by retaining cams 19 projecting into it.
  • a plurality of webs 21, which originate from the inner surface of the jacket, are provided, which hold the seal 17 in the intended location.
  • threads 23 can be seen, which mesh with a corresponding external thread on the outside of the container.
  • ribs 25 are provided which extend in the axial direction and increase the grip of the closure 1.
  • At least one bridging web 31 remains in each case, which forms a connection between the end regions of the ring segments 33 separated by the vertical incisions 29.
  • the bridging webs 31 can be formed in that when the vertical incisions 29 are made, a knife with a groove is provided which leaves an area of the wall 27 of the guarantee ring 9 intact. It is also possible for a radially inwardly offset web to be applied to the inner surface of the guarantee ring 9 in the region of the vertical incisions, which, like the tear-off webs and the holding web 15, remains intact during a cutting process with a defined depth.
  • protrusions 37 run obliquely downwards, which are provided on their upper side with stiffening ribs 39 which, starting from the front side 41 of the protrusions 37, fall in a ramp shape towards the inner surface 35 of the guarantee ring 9 and in one Pass into the surface of the projections 37 in front of this inner surface.
  • the front surface of the stiffening ribs 39 forms a common stop surface with the front surface of the projections 37.
  • the projections 37 are designed in such a way that they arise at a distance from a holding web 15 from the inner surface 35 of the guarantee ring and, on their side facing the holding web, slope away at an angle Side edges 43 are provided.
  • the side edges 45 provided on the opposite side of the projections form a right angle with the inner surface 35 of the guarantee ring 9. The distance between these side edges 45 and a vertical incision 29 lying directly next to them is substantially less than that of the adjacent holding web 15.
  • FIG. 2 shows a top view of a guarantee ring 9 cut off along the line II-II, which is shown in FIG. 1.
  • the cut-off tear-off webs 11 and 11/1 and 11/2 can be seen from the plan view according to FIG. 2, and the section through the holding webs 15 can also be seen.

  • the width of the grooves 47 is chosen to be larger than the width of the holding webs, which are arranged centrally in relation to the groove.
  • the tear-off webs 11 and the holding webs 15 consist of material areas which are offset radially inwards so that they remain practically intact in a defined horizontal section through the wall 27 of the guarantee ring 9.
  • the closure 1 or its guarantee ring 9 is provided with a plurality of shaped elements which are arranged on the outer or on the inner surface of the guarantee ring 9. Using these shaped elements, an alignment of the closure can be ensured during the introduction of the vertical incisions 29.
  • the projections 37 or their side edges 45 and 43 can be used here.
  • the position of the holding webs 15 on the inner surface 35 of the guarantee ring 9 can also be used for the exact alignment of the closure.

  • the inner centering device 55 In the end position, in which the inner centering device 55 is completely extended by advancing the guide sleeve 61, the inner centering projects beyond both the end face of the pressure plunger and the feeler pin of the outer centering device 59, so that there is no longer any fear of the closure itself being displaced by the tool itself .
  • the feed movement of the inner centering device 55 ensures that the cutting device does not come into engagement with the outer centering tool when the horizontal cut is made to produce the predetermined breaking line 13 or when the longitudinal incisions 29 are made in the longitudinal direction. This prevents damage to both the cutting device and the tool 50.
  • a knife with a continuous cutting edge can also be used if, on the inner surface 35 of the guarantee ring 9, similar to the tear-off webs 11 and the holding webs 15, radially inwardly displaced material areas are provided, which are not damaged at least during the cutting process with a defined depth remain essentially uncut.

It is only necessary that the relative arrangement of the scanned contours or shape features to the position of the vertical incisions to be introduced is known, so that the merging of tool 50 and cutting device, which is not shown here, can be carried out accordingly so that the vertical incisions in the Desired, predeterminable position can be introduced. For example, they can be placed on the end regions of two adjacent ring segments 33, so that these end regions are held by the tear-off webs 11/1 and 11/2, the cut of the vertical incisions 29 is preferably introduced into the bottom of the V-shaped recess 49. In this way, relatively little material can be cut, so that the service life of the knives is significantly increased.
  • the vertical incisions 29 are arranged in the immediate vicinity between the side edges 45 of the projections 37 which drop perpendicularly to the inner surface 35, where when the first opening Closure the maximum force is introduced into the guarantee ring. Even if the vertical incisions through the bridging webs 31 are given a certain strength, it is ensured that the guarantee ring 9 of the closure 1 is opened when it is opened for the first time.
  • the barbed projections 37 engage under the aforementioned projection on the outside of the container and lead to axial and radial expansion forces on the guarantee ring, so that the latter is blown open.
  • the retaining webs lie in the pivot and pivot point of the ring segments 33 and remain intact when the guarantee ring is opened. They are designed so firmly that they hold the ring segments that have been blown open in their pivoted position, so that the consumer can easily recognize manipulations on the closure.
  • the external centering can be dispensed with.
  • the inner centering device 55 is moved against the closure fixed by a holder until the shaped element 79 engages in the given inner contours of the closure and holds it securely.
  • a vertical incision can subsequently be made in a plastic closure, which is produced, for example, in a plastic injection or compression molding process, at a precisely predeterminable point.
  • the positioning of the vertical incision depends on shape features attached to the inside and / or outside of the closure, which can be scanned using a suitable device.

  • the vertical incision is preferably placed in the middle of such a guarantee area, that is to say in an area which is subjected to a maximum axial and radial displacement when the closure is opened for the first time. On this ensures that the vertical incision is blown open the first time it is opened, so that manipulations on the closure can be easily recognized by consumers.
  • the end areas of such a guarantee area are firmly connected to the rest of the jacket. In this case, there is no need for holding bars that hold the segments after the vertical cut has been opened. Rather, the segments are firmly connected to the rest of the closure via their end regions and cannot be lost.
  • closures can also be implemented, which also have two guarantee areas, which when opened for the first time are broken open into segments which in turn are held by means of retaining webs.
  • closures can also be implemented, which also have two guarantee areas, which when opened for the first time are broken open into segments which in turn are held by means of retaining webs.
  • the introduction of the vertical incisions can ultimately be independent of the special design of the one used for the positioning Shape features take place.
  • the exact arrangement of the vertical incisions can be adhered to in any case, the shape features being able to be arranged on the inside and / or on the outside surface of the closure.
  • the horizontal cut which extends over a circumferential area or along the entire circumference and through which the guarantee area or a guarantee ring is generated, can be made in an independent, independent process step during their manufacture.
