Definitions

  • the invention further relates to an assembly method for a closure for a container neck with a thread or undercuts.
  • an invulnerable closure cap for bottles, flacons and similar vessels in which the main piece, which consists of a one-piece plastic mass, has a locking ring which is connected to the main piece by at least one annular region with weak resistance, and at the first opening of the vessel, this area can be easily torn open by means of tensile force.
  • This cap is made from a single piece of plastic.
  • manufacturing difficulties can arise because the relatively coarse closure cap also includes the finely divided locking ring; in the spraying process, however, this means an inequality in the required spraying times between the sealing cap itself and the locking ring.
  • plastic caps are not always to be used; especially for beverages with high carbon dioxide pressures. the pressure-resistant metal caps are missing.
  • Metal closure caps are known, on the lower edge of which a metal ring is formed via connecting webs, which remains on the bottle neck when the metal cap is turned while the connecting webs are broken. But the disadvantage of such a closure is that after opening the metal cap and breaking the connecting webs, sharp metal edges can arise, so that there is an increased risk of injury to the user.
  • Such metal caps are only usable for container necks with low manufacturing tolerances, since the metal cap can hardly be changed in its own dimensions.
  • the lower part of the circlip also has an obliquely inwardly pointing lip drawn towards the upper part; on the outside, however, a protrusion protruding over the bead of the closure cap is formed on this lip, which protrudes against the outermost, flanged bottom edge part of the closure cap.
  • closure cap itself can be made of metal, while the locking ring is designed as a plastic ring.
  • the outwardly projecting projection on the lip should rest on the bottom part of the edge of the metal cap, which is flanged in the form of an annular channel, so that a lever effect of the projection ensures that the lower part of the plastic ring does not simply escape to the outside; because otherwise the lip of the plastic ring would dodge outside on the clamping bead of the container neck without the plastic ring then tearing apart along the zone of reduced resistance.
  • the circumference of the metal cap could also be widened in the same direction without the stable, flanged bottom edge.
  • EP-A-0034 997 a one-piece plastic cap is known, the securing ring of which can be shrunk by heat treatment on the container neck under its clamping bead. Otherwise, such a plastic cap also has the disadvantages already mentioned.
  • DE-OS 22 33 305 relates to a screw cap made of metal with tamper-evident locking ring which engages under a retaining ring on the outside of a container mouth, which is characterized in that the locking ring is made of plastic, preferably a polyolefin or the like, and is attached to the lower edge of the screw cap is, the outer projection on the upper part of the locking ring is designed as an outwardly facing edge or as an annular bead and the lower part of the locking ring has no outward projection, so that the plastic ring has a substantially Z-shaped cross section.
  • the present invention has for its object to provide a cap with a separate locking ring made of plastic, so that not only the materials of the two parts can be selected independently of one another, as in DE-A-2 233 305, but also the locking ring If possible, plastic cannot be destroyed unintentionally.
  • the plastic locking ring thus has the shape and effect of a barb. This encourages the ring to tear when the closure is opened.
  • the fact that the retaining ring is somewhat wider than the neck of the container so that it can be easily pulled over it does not do any harm. Material is also saved since there is no voluminous, outer projection on the lower part. Since this outer protrusion is no longer available, it is no longer possible to accidentally tear the plastic ring on this outer protrusion without opening the closure.
  • a special embodiment of the present invention is characterized in that at least the lower part of the locking ring is designed to be shrinkable.
  • closure cap is arranged over the retaining ring and then the lower peripheral edge of the closure cap is flanged over the outwardly facing edge of the plastic ring, without doing so flare the bottom edge outwards.
  • FIG. 1 Further particular embodiments of the mounting panel according to the invention f ahrens are characterized in that the bead obliquely over its circumference at the top is inclined inwards, and that the lower inwardly beaded edge of the closure cap is pressed upwardly so that the bead on its periphery by is inclined inwards at the top.
  • closure cap is claimed, which is characterized in that it is produced by the assembly method according to the invention.
  • the securing ring or the bead can also be designed to be shrinkable.
  • at least the lower part of the plastic ring and optionally the bead of the closure cap can additionally be made shrinkable. In this case, particularly large tolerances of the container neck can be compensated for.
  • a further saving of material with almost constant stability of the locking ring and a reduction in the play when the locking ring is pulled over the neck of the container can be achieved with a plastic ring.
  • Accidental destruction of the circlip, especially when pulled over the neck of the container is even less likely.
  • the lower part of the plastic ring is also designed to be shrinkable, the shrinking process allows the lip to be positively enclosed by the outer, lower part and, as a result, form a practically one-piece lower part.
  • a plastic ring with lines of weakness is preferred.
  • the plastic ring can then tear open over its circumference and fall off the neck of the container. As a result, it can be prevented that the lower part of the plastic ring remains on the container neck and only has to be laboriously removed afterwards when the container is refilled.
  • the zone of reduced resistance between the upper and the lower part of the plastic ring can be formed by alternating interruptions in the plastic ring provided by connecting webs.
  • the connecting webs can preferably be arranged in the upper third and the openings in the lower third of the plastic ring.
  • the weakening lines can be V-shaped in cross-section, that is, without openings or material recesses being provided.
  • a still possible problem of the closures listed is that the plastic ring does not tear open and off completely from the closure cap. If you then put the cap back on the neck of the container, you can slide the lower part or parts of the plastic ring, which have been torn off, but which have got stuck on the upper part, back up to the upper part of the plastic ring just below the lower edge of the cap. Then, however, the lower part of the plastic ring of the sealing cap, which is visible from the outside, can no longer be readily seen that it has been torn open, that is to say that the container has already been opened. In order to prevent such deception, the plastic ring can then be designed according to claim 5. For this, a special assembly process is still required, which will be specified in detail later.
  • the plastic ring is designed as claimed in claim 7, then a deception protection is given in the usual assembly according to claim 8.
  • the extensions of the lip will push the torn open parts of the lower part of the plastic ring outwards from the container base, in particular from the clamping bead.
  • at least individual parts of the lower part of the plastic ring spread apart and can no longer be bent back to deception and can be placed on the neck of the container under the lower edge of the closure cap.
  • the upper part of the plastic ring arranged in the same is braced due to the inclination of the bead. If the lower part of the plastic ring is now torn open by the container neck in a line of weakness arranged transversely to the circumferential direction when the closure is opened, the stable retaining webs or bridges between the upper part and the lower part become due to the tension given to them by the upper part in this partial area of the lower part Spread part of the plastic ring from the neck of the container. Even then it is no longer possible to simply slide this spread-out part of the plastic ring inwards again towards the upper part under the sealing cap.
  • a known cap z. B. made of metal. It contributes to easier turning to open a profile edge 31.
  • the cap wall 32 is not yet on the thread of the container neck is flanged and therefore still smooth.
  • the bead 4 of the cap which is formed on the lower edge 3 and is shaped on the outside, can be clearly seen. This is used to hold the upper part of the locking ring made of plastic.
  • FIG. 2 shows a plastic ring 7 itself in a perspective view; it is a plastic ring with a Z-shaped cross section, but without stable retaining bars. The latter are described in the exemplary embodiment in FIG. 3.
  • this plastic ring 7 alternately has separating webs 10 and openings 11 in the upper third. Together they form the zone of reduced resistance.
  • three equally distributed weakening lines 13 are arranged transversely to the circumferential direction 12; they continue into lip 26. If you insert this plastic ring 7 into the closure cap 1, so that the outwardly facing edge 8 of the plastic ring 7 engages in the interior of the bead 4 of the metal cap 1, a closure cap is formed which can be applied to a container.
  • a plastic ring is shown, which has the special toothing between lip 26 and the outer, lower part 24 and stable retaining webs 28.
  • the upper part 23 and the lower part 24 can be clearly distinguished overall. These two parts are connected to one another by the stable holding webs 28.
  • the holding webs 28 are significantly stronger than the much thinner separating webs 10, which should tear when the cap is unscrewed. However, the holding webs 28 should not tear.
  • the separating webs 10 bridge the zone 25 of reduced resistance in the form of a gap while leaving openings 11.
  • the Tear off the lower part 24 from the holding web 28, just as the separating webs 10 can tear apart when the container is opened. As a result, this lower part of the plastic ring then only hangs at its other end on another holding web, since such a weakening line is not provided on this side.
  • the groove 30 can be clearly seen on the inside of the outer, lower part 24 of the plastic ring 7 opposite the lip 26.
  • the lip 26 itself has a toothing 27 opposite the groove 30.
  • the teeth 35 of the toothing 27 are each arranged opposite the grooves 34 of the groove 30.
  • the lip of the container neck in particular its thread and clamping bead, is pressed outwards when the plastic ring is slipped over the container neck, the lip can move into the grooves of the grooves, although due to the toothing it is stiff as is the outer, lower part of the plastic ring.
  • FIG. 4 again shows a detail of a section of the plastic ring from FIG. 3. It can be clearly seen here that the separating web 10 forms only a very thin connecting line between the upper part 23 and the lower 24. It therefore tears open easily.
  • the grooves 34 run together in the lower part 24 downwards; The same applies, however, which is not visible, for the teeth 35. This prevents the grooves 34 or the teeth 35 from continuing into the bend at the bottom in the lower part 24.
  • a groove 34 is opposite a tooth 35.
  • a back 33 of the ride 30 is opposite a recess 36 of the teeth 27.
  • the teeth 35 can escape into the grooves 34 and the backs 33 into the recesses 36.
  • the lip 26 appears to be only half the thickness of a conventional lip, although it is practically just as rigid is.
  • this toothed lip can escape particularly far out into the outer part of the lower part 24, while still having a stable clamping or hooking effect on the container neck.
  • FIG. 5 shows another embodiment of a plastic ring, in which the bracing may be caused solely by the special extensions 29.
  • These extension tongues can be isolated, that is to say separated from the rest of the lip 26, otherwise arranged approximately parallel to the lip 26 on the lower part 24.
  • a cross section through this plastic ring is shown, the cross section leading through an extension 29 according to the innovation.
  • FIG. 6 shows the section through a closure cap 1 placed on a container 14 and having a plastic ring 7 with a Z-shaped cross section.
  • the cap thread itself is already crimped into the cap wall 32 corresponding to the container neck thread 20.
  • the opening edge of the container neck 15 is sealed under the cap lid 2 by the sealing insert 5.
  • the clamping bead 16 is provided on the outside of the container neck 15 below the container neck thread 20. It serves as a lock for the inward, obliquely upwardly directed lip 26 of the plastic ring 7. Even below, ie outside the bead 4 and its lower edge 3 of the closure cap 1, the zone 25 of reduced resistance is arranged in the form of openings 11.
  • FIG. 7 An embodiment of a plastic ring is shown in FIG. 7, in which a bracing is brought about by special extensions 29.
  • These extensions 29 can be arranged individually, that is to say separated from the rest of the lip 26, on the lower part 24 otherwise running approximately parallel to the lip 26. They are so long that they cannot get under the clamping bead 16 like the rest of the lip 26, but rather have to be supported with the free end against the clamping bead 16. It is particularly advantageous if these extensions 29, like the lip 26 in FIG. 4, are also provided with a toothing which, on the other hand, corresponds to scoring on the outer, lower part 24.
  • a toothing which, on the other hand, corresponds to scoring on the outer, lower part 24.
  • the undetectable back which can slide into a corresponding recess 36 in the extension 29.
  • the upper part 23 is connected to the lower part 24 via stable retaining webs (not shown)
  • the torn-open parts of the lower part 24 of the plastic ring 7 are spread apart on suitable weakening lines. Since the individual ring parts of the circlip 7 are held by the retaining webs on the upper part 23 in the bead 4 of the cap 1, they signal that a circlip had really been present, but which is now torn open; so the user can not be faked that the bottle had no safety plastic ring at all, so that it would not be possible to check the opening of the container for the first time.
  • FIG. 8 shows how the plastic ring 7 can be pretensioned by deforming the bead 4.
  • the bead 4 on the lower edge 3 of the closure cap is inclined upwards obliquely inwards.
  • the lower part 24 can also be stretched or compressed to a certain extent in the region of the zone 25 of reduced resistance. If the lower part 24 of the plastic ring tears open at any weakening line 13 arranged transversely to the circumferential direction when the closure is opened, the tension manifested as an inclination of the upper part 23 can inevitably be transmitted to the torn lower part 24 through the stable holding webs 28. This then inevitably seeks to lay parallel to the upper part 23; as a result, the torn parts of the lower part 24 of the ring feed from the container neck 15 to beyond the edge 3 of the cap to the outside. As a result, the torn parts of the lower part 24 of the plastic ring can also no longer be pushed inwards in order to simulate an untorn plastic ring.
  • the new closure is particularly suitable for carbonated liquids such as mineral water or corresponding drinks.
