Definitions

  • the invention relates to a guarantee ring for a screw cap for closing containers, in particular reusable bottles, which is preferably injection molded from a plastic which can be deformed to enclose the vessel mouth collar and the screw cap, and is held by an inwardly directed ring web running around the top of the ring at the lower edge of the screw cap is and has a predetermined breaking point, which runs around half the height of the bridge horizontally on the circumference of the guarantee ring.
  • a guarantee ring for a screw cap which is injection molded. It has an inwardly directed ring web running around the upper edge of the ring, by means of which it rests on the lower edge of the screw cap.
  • a screw cap equipped with such a guarantee ring is screwed onto the bottle neck and then the ring is deformed.
  • the guarantee ring lies firmly under the lower edge of the vascular mouth collar, thereby securing the screw cap.
  • the guarantee ring pops up at one point and then falls down on the bottle neck.
  • An advantage of this guarantee ring is that it can no longer be used after opening the screw cap. This can prevent the beverage from being falsified. There is also no risk of injury. Another advantage is that the guarantee ring can be manufactured extremely inexpensively by injection molding and is therefore well suited for mass production.
  • this guarantee ring partially gets stuck on the bottle neck when the screw cap is opened. Although it can be easily removed since it is open at one point, this must be taken into account by the consumer or by the re-user of the bottle. If this does not happen, however, the bottle will return to the filling station, where the guarantee ring must then be removed. This can be done using appropriate brushing machines, but their purchase and operation cause high costs.
  • the same problem also occurs with the ring known from DE-OS 19 48 634.
  • This ring is also similar in design to that of DE-PS 21 44 628, but additionally has a predetermined breaking point, which runs horizontally around half the height of the ring on the circumference of the ring. When the screw cap is opened, the ring tears over its circumference along this predetermined breaking point, so that the lower part is relatively thick-walled slips off the bottle neck and gets stuck there. It must then be removed by means of correspondingly complex devices.
  • the invention has for its object to form the guarantee ring of the type mentioned in such a way that it no longer gets stuck on the bottle neck after unscrewing the screw cap and is easy and safe to manipulate.
  • the predetermined breaking point is designed as a film-like predetermined breaking ring web, from which at least one predetermined breaking cross-web, which also extends to the lower edge, extends, and in that the upper and lower ring parts connected by the predetermined breaking ring web are arranged in relation to one another that the inside of the lower ring part continues in the inside of the predetermined breaking ring web and the outside of the upper ring part in the outside of the predetermined breaking ring web, the plastic shrinking with appropriate treatment Material is used.
  • the lower part of it is blown off when the screw cap is opened, which parts can no longer get caught on the bottle neck.
  • This is caused by the two predetermined breaking crosspieces or the one predetermined breaking crosspiece together with a further predetermined breaking point, which is formed from the junction of the plastic mass in the injection mold, whereby the lower part of the guarantee ring breaks into two parts.
  • These two parts separate at the same time in the area of the predetermined breaking ring web due to its thin cross-section cleanly from the upper ring part.
  • the previously required machines for removing the known guarantee ring can thus be dispensed with, which also saves the energy required for these machines.
  • the thin cross-sections of the predetermined breaking ring web and the predetermined breaking cross web or end on the one hand withstand the shrinking process and do not impair it, in particular do not tear or break, and on the other hand because of the embrittlement when the Open the screw cap immediately, so do not get caught on the upper part of the bottle.
  • the weakening achieved in this way at the places provided for this purpose therefore has no adverse effect on the known advantageous properties of the guarantee ring.
  • the special design of the cross-section of the guarantee ring makes the injection molding of the locking ring easier and, in addition, ensures the very favorable shrinking properties.
  • the reusable bottles can be securely sealed without any special manipulation effort, since the ring consisting of the ring parts and the screw cap are connected together to form a component before being taken over by the bottle .
  • the screw cap and ring are expediently connected to form a component before being taken over by the bottle, in that the ring web can be snapped into a groove formed in the screw cap, which is preferably formed on the lower edge and a bead formed in the screw cap.
  • the groove is either open to the inside of the screw cap or to the outside thereof, so that the ring has to be pushed on from the outside or inserted into the screw cap from below.
  • At least two predetermined breaking transverse webs start from the predetermined breaking ring web in order to ensure that the lower ring part shatters into two parts.
  • the predetermined breaking crosspieces should be arranged at the same angular distance from one another so that the same parts are created.
  • the predetermined breaking ring web has a height of 0.5 mm, preferably 0.2 mm.
  • the width of the predetermined breaking crosspiece or webs is 1 mm, preferably 0.5 mm, while the thickness of the predetermined breaking ring web and / or predetermined breaking crosspiece is not greater than 0.2 mm, preferably 0.1 mm.
  • an axial web is arranged on the outside of the upper ring part of the guarantee ring, the outside of which merges into that of the lower ring part.
  • the upper edge of the guarantee ring should have a conical bevel that continues in the axial web.
  • the guarantee ring provided with such predetermined breaking points has the necessary stability for the manipulation and final production of the seal.
  • the necessary stability is further generated in that the ring is step-shaped or has corresponding folds or beads.
  • the individual rings are prevented from jamming into one another or against one another by chamfering the free part of the upper edge of the lower ring part, preferably chamfering at 35 °.
  • Manufacturing is simplified by providing teeth on the inner surface of the ring web that are spaced apart from one another or perpendicular transverse webs that ensure that the ring web engages securely in the groove provided in the screw cap, even if the ring web itself does not have the necessary dimensional accuracy overall should have. They are designed so that they jump off if necessary if it should turn out to be the case that the ring or ring web is dimensioned and manufactured with too great accuracy. If the teeth or crossbars remain, they lead to an optimal fit of the ring web into the groove during the heat treatment, because the corresponding material can be deformed and adapted by heating.
  • the invention is characterized in particular by the fact that a guarantee ring for screw caps, in particular for water bottles, is created, which enables secure sealing without excessive installation effort and, on the other hand, ensures that when the seal is opened, it cannot be apparently restored by appropriate manipulations. Rather, the guarantee ring disintegrates when the screw cap is opened or unscrewed accordingly, whereby it is ensured that no remnants remain on the bottle neck itself, so that the bottle can be reused immediately and without the use of residual removal devices.
  • the firm connection between the screw cap and the guarantee ring before feeding both to the filled bottle ensures that the guarantee ring always occupies the same position. This ensures that the sealing is always the same and secure.
  • Fig. 1 shows in the left half in vertical section and in the right half in the view a bottle 1 on which a screw cap 2 is seated.
  • the upper part of the bottle neck of the bottle 1 has a screw thread 3 which corresponds to a corresponding screw thread 4 in the screw cap 2.
  • An elastic sealing plate 5 is arranged in the bottom of the screw cap 2, by means of which the necessary tightness of the closure is ensured.
  • the state shown in FIG. 1 is in the left half the time after completion of the screw thread 4 in the screw cap 2 and before the necessary heat treatment and the shrinking of the actual guarantee ring.
  • 1 right half shows the finished sealing of the bottle 1, i.e. that is, the bottle with the screw cap after the end of the heat treatment.
  • the screw cap 2 has a circumferential bead 6 which, together with the flanged lower edge 5, forms a groove 19 into which a guarantee ring 8 made of polystyrene as an injection molded part surrounds with its upper part, ie with the ring web 15.
  • the guarantee ring 8 is captively connected to the screw cap 2.
  • the left part of the Fi g. 1 shows the guarantee ring 8, as mentioned, in the unshrunk state. It is about the same Height with a bulge 9 on the bottle neck of bottle 1. If the bottle 1 after filling and screwing on the screw cap 2 is passed through a correspondingly hot heating zone, the guarantee ring 8 shrinks in such a way that the lower part slides under the bulges 9, as shown in the view in the right part of FIG. 1 is. The bottle is then secured or sealed.
  • the guarantee ring 8 has a predetermined breaking ring web 10, which is only indicated in FIG. 1, and two predetermined breaking transverse webs 11, which extend from the latter to the lower edge 7 and are diametrically opposite.
  • the guarantee ring 8 is also lifted, its lower part having to widen because of the bulge 9. Since the material of the guarantee ring 8 is embrittled due to the shrinking process, it tears open immediately, specifically at the predetermined breaking guerstegs 11 and the predetermined breaking ring web 1o because of their greatly thinned cross sections. As a result, the two ring parts 12, 13 which are formed thereby fall away, while the upper ring part 14 of the guarantee ring 8 is held in the groove 19 formed by the bead 6 and the lower edge 7.
  • Fig. 2a shows a substantially enlarged cross section through such a guarantee ring 8. From this it can be seen that the upper ring part 14 with the lower, consisting of the two ring parts 12, 13 ring parts are only connected by the film-like thinned predetermined breaking ring web 1o, both parts are radially offset from one another.
  • the dotted line shows the cross section of a Sollbruchste g is 11, which corresponds to the predetermined breaking of the annular web 1o.
  • the upper ring part 14 of the locking ring 8 also has an axial web 16, the outer surface of which runs upwards into the slope of the upper ring part 14 and downwards into the outside of the lower part. Its extent in the circumferential direction corresponds approximately to that of the predetermined breaking crosspiece 11.
  • the ring web 15 is equipped with teeth 25, 26 running on the inner surface 24, it being possible for the teeth to protrude slightly above the edge 27.
  • the upper edge 20 of the lower ring part 12, 13 is chamfered, preferably by 35. This slope is provided similar to the upper slope of the ring web 15 in order to facilitate the sorting of the individual guarantee rings 8.
  • FIG. 2b shows an annular web 15 with an embedded groove 3o.
  • This groove 3o corresponds to the bead 6, which it comprises when the ring 8 is pushed onto the screw cap 2.
  • the lower part of the ring web 15 now forms a further web 31, which in turn projects into the groove 19 between the bead 6 and the lower edge 7. This creates a double backup.
