Definitions

  • the invention relates to a Investigationieschraubver gleich for containers and bottles, in particular for plastic bottles, according to the preamble of patent claim 1.
  • plastic screw caps are usually in a Spritzgiessverf ears or produced in a die-casting. Most plastic closures are designed as so-called Investigationieschraubver till.
  • the actual screw cap of the closure is connected to an annular guarantee strip, which is connected to the free edge of the jacket of the screw cap via sole breaker webs.
  • the circumferential flange usually also to a certain extent ensures that the guarantee band can not join the axial movement of the screw cap and the predetermined breaking points are additionally broken by the tensile load between the screw cap and the guarantee band.
  • the projecting from the inner wall of the guarantee strip protrusions are usually wedge-shaped in the direction of closing. This is to facilitate the screwing on the InvestigationieschraubverBankes.
  • the projection of the protrusions on the inner wall of the guarantee band is only relatively small.
  • the guarantee strip must be made relatively narrow, so that the inwardly projecting projections come into engagement with the corresponding projections on therobonhalswandung. Due to the design, this results in a relatively large Aufschraubkraft that must be applied so that the first time screwing the warranty screw cap on a container or a bottle, the guarantee strip can be pressed with the protruding projections on the peripheral flange. So that the predetermined breaking webs do not break when the warranty screw cap is first screwed on, they must be of relatively stable design. This in turn results in a relatively large unscrewing force that must be applied so that when unscrewing the ISieschraubverInstitutes the guarantee strip is separated from the screw cap.
  • the screw cap must be pulled and pulled many times until the guarantee strip loosens completely. Often then runs the guarantee band in part above the peripheral flange of the bottle neck, which is a hindrance when re-screwing the screw cap to close the container or the bottle. If the guarantee strip does not come loose from the screw cap, it can happen that the entire warranty screw cap is unscrewed unscrewed if the dimensions of the neck are larger. In this case, the warranty screw cap fails completely in its function of indicating integrity, and the consumer may be given the impression that the contents of the container or bottle may be tampered with.
  • the guarantee band has a Congressrandwulst and radially inwardly projecting lobes.
  • the flaps are articulated via an articulated bending area with a thinner cross-section at the inner edge bead.
  • the guarantee band has fishhook-like inwardly bent lobes.
  • the guarantee band is connected via predetermined webs provided with predetermined edges with the mantle edge of the closure.
  • the ImplantieschraubverInstitut described in GB-A-2269372 has a guarantee strip, which is connected via predetermined ribs with the jacket of the screw cap. Between the relatively stable formed ribs protrude from a lower edge of the guarantee ring wedge-shaped locking body radially inwardly. In the circumferential direction material taper form filrnscharnierieri bending joints for the wedge-shaped locking body, so that they can slide when bouncing the Investigationieschraubver gleiches a circulating on the bottle annular bead.
  • the closure for milk bottles described in WO 97/35773 is not an actual screw cap. Rather, it is a snap, which can be unscrewed by turning.
  • the snap closure has two locking systems that are adapted to a specially designed neck. It is also a guarantee ring provided, which is connected via thin, breakable Anbindestege with the cap. From the guarantee ring locking tabs protrude radially inward, which engage when placing the snap closure in special recesses on the circumference of the bottle neck. Window-like recesses on the guarantee ring are intended to guarantee the elasticity of the locking straps.
  • US-6,325,227 B1 which forms the closest prior art, discloses a guarantee screw cap for bottles with a flange which extends annularly around the neck of the bottle and has a screw cap and an integrally formed guarantee strip.
  • the screw cap has a cylindrical shell.
  • the ring-shaped guarantee strip is provided with window-like recesses which extend between relatively solid webs. In the contact region between the webs and the free lower edge of the jacket of the screw cap breakaway webs are provided.
  • wedge-shaped locking cams extend radially inward.
  • the window-like recesses are formed in the manufacture of the screw from laterally and radially adjustable slides, which are delivered to the formation of the wedge-shaped locking cam on the injection mold.
  • the object is to create a plastic guarantee screw cap for containers and bottles, in particular for plastic bottles, the guarantee band of which can be separated reliably from the screw cap during unscrewing and without excessive expenditure of force.
  • Mass variations of the neck of the container or the bottle and ovality of the neck should be able to be compensated.
  • the installation of the Informieschraubver- lock should be easy and without increased Auf loft mechanism or Aufklell mechanism betechnikstelligbar.
  • the warranty screw cap should allow the consumer to visibly and unambiguously recognize the integrity visually. He should be in one as simple and inexpensive tool in an injection molding or in a die-casting process to be produced. The service life of the tools should be higher than in machines for the production of the known Druckieschraubver barely. When manufacturing the warranty screw cap, material should be saved without compromising functionality and reliability.
  • the invention provides a guarantee screw cap made of plastic for containers and bottles, in particular plastic bottles, consisting of a screw cap which has a cylindrical jacket with internal thread, and an annular guarantee strip which is connected via predetermined breaking webs or the like to the free edge of the shell and with locking elements equipped, which are designed for a positive engagement in a formed on a container or bottle neck abutment created.
  • the guarantee strip has an outer diameter which is smaller than that of the jacket of the screw cap.
  • the locking elements are formed by chamfered or chamfered undercut areas of the guarantee strip, each extending ring segment-like between two adjacent predetermined breaking webs and extending from an axially longer cylindrical inner wall to an axially shorter outer wall of the guarantee band.
  • the locking elements are designed for positive cooperation with a peripheral flange provided on a container or bottleneck flange and extend in the axial direction perpendicular to the direction of twisting the Informieschraubver gleiches. In contrast to wing or flap-like barrier elements, they extend in the circumferential direction between two adjacent predetermined breaking webs.
  • wing or flap-like barrier elements they extend in the circumferential direction between two adjacent predetermined breaking webs.
  • Bottlenecks and out-of-roundness are compensated. As you continue to unscrew, the forces on the breakaway webs increase, and they always break off in the same quality and completely.
  • the forces acting on the breakaway webs are primarily tensile forces, which are superimposed to some extent by shear forces. Since no positive connection of the guarantee band to

  • the guarantee strip has a smaller outer diameter than the screw cap are in the assembled state of the InvestigationieschraubverInstitutes its undercut areas as close to the neck circumference arranged without rubbing during the unscrewing of this. Because of the lower use of material on the guarantee ring is on the one hand given sufficient elasticity during demolding and closure of a bottle and on the other hand still guarantees the functionality of the Informieschraubver gleiches. In addition, material can be saved by this measure.
  • the guarantee screw lock formed according to the invention can be produced.
  • adjustable slides or the like movable mold parts can be dispensed with in the mold.
  • the tool is mechanically less heavily loaded and it has a longer service life.
  • the simpler tool design also has an immediate beneficial effect on the cost of the tool.

  • An inner diameter measured at the undercut areas of the guarantee strip is expediently larger than the inner diameter of the screw cap at the inner thread sections. This ensures that the guarantee band can slide without obstruction over the external thread on the neck of the bottle during assembly of the guarantee screw cap and prevents tilting of the guarantee screw cap.
  • the locking elements must have a certain rigidity. This is ensured, in particular, by its ring segment-shaped extent in the circumferential direction. It proves to be an advantage if the undercut segments extending in the manner of a ring segment between the breakaway webs have a circumferential extent which corresponds to 60% to 100% of the distance measured in the circumferential direction between two adjacent longitudinal edges of two adjacent breaker webs.
