Definitions

  • the present invention relates to a screw cap, consisting of a screw cap and a guarantee strip, wherein the screw cap has a head plate with a cylindrical Kappen Mantelmantel provided with an internal thread, and wherein the guarantee strip has a flex band and one or more easily tearable elements is connected to the lower edge of the cap skirt, wherein the flex band is formed as a continuous circumferential Flexband having distributed over its circumference a plurality of easily stretchable sections and relatively less easily stretchable sections between them, and wherein the easier stretchable sections a smaller wall cross-section, in particular in the folded state have a lower measured in the radial direction wall thickness than the less easily stretchable sections.
  • Such screw caps are in numerous use, in particular for container mouths or closure bottoms, whose diameter is 38 mm or less.
  • the hinged part of a guarantee strip which extends during and immediately after production approximately in the axial extension of the cap skirt and an outer guarantee band section, but which folds inwards and upwards (in the direction of the top plate) is and whose free end has an upwardly facing in the folded state abutment surface, which applies when loosening a screw cap to the underside of a retaining ring when located on a closure bottom or a corresponding container neck below the mating to the screw external thread.
  • Such flexbands are known in a variety of configurations, especially in the form of separate, individually foldable segments and with interruptions, which should facilitate the application of an intact closure and in particular the intact guarantee band on the container neck or a corresponding lower part.
  • the free inner diameter of the flex band, which sets in the folded state must be significantly smaller than the outer diameter of the retaining ring on the container neck or closure bottom, which is to engage behind the Flexband.
  • the flex band which is connected via a weak point acting as a hinge with the outer portion of the guarantee band, unrolls when acting on an axial force on the free end, specifically when engaging with the underside of the locking ring during unscrewing the screw simply down and folding back into a position in which it essentially forms an axial extension of the outer portion of the tamper-evident band and in this way can slide over the circlip, on the one hand, it must have sufficient rigidity in itself, and it must be in the folded state at a relatively acute angle (with respect to the cylindrical inner wall of the outer guarantee strap portion) extend upward.
  • an axial force acts predominantly in the longitudinal direction of the more or less cylindrical or slightly conical wall of the flex belt and exerts on the hinge portion a corresponding axial tensile force on the outer portion of the guarantee band, which is sufficient to rupture the easily breakable connection or connections between The guarantee strip and the lower edge of the screw cap leads.
  • a screw cap and its flex band are sufficiently matched in their dimensions to a bottleneck or a corresponding closure bottom, so that the flex band after application of the screw cap on a container neck or closure bottom, if it is below rests on the outer circumference of the container neck, assumes a corresponding position in which the wall of the flex band with the wall of the outer portion of the guarantee strip or with the axis of the closure includes a sufficiently acute angle, which should not exceed 30 ° if possible ,
  • the container necks produced by blow molding often have significantly greater inaccuracies and typical tolerances of up to ⁇ 0.3% or more.
  • This is particularly disadvantageous for large diameters of 35 mm and above, because in such a case screw caps with corresponding flex bands, which are placed on the nominal size of such container necks or closure bottoms, no longer fit exactly to the container necks thus produced.
  • it may happen that in a produced by blow molding container neck with a nominal diameter of 63 mm, the outer diameter of the container neck below the retaining ring in the case of a tolerance deviation of - 0.3% by up to 0.2 mm smaller than the nominal size.
  • the effective softening of the diameter of the guarantee strip in the region of the hinge section and the outside diameter of the container neck below the retaining ring is 0.3 mm compared to the corresponding nominal dimension.
  • the upper end of the flex band which is the smallest diameter of the flex band and rests with its inner upper edge on the outer surface of the bottle neck, can dodge further inwardly by 0.15 mm (tilting about the hinge portion) than at Compliance with the nominal dimensions.
  • the consumer will then tear off such a loosely hanging and annoying in the reuse of the screw cap guarantee strip, or the guarantee strip can tear off by itself in the further handling of the closure, which in turn carries the risk that it is in the container falls or falls into another container in which the liquid contained in the container is to be poured out.
  • the liquid or substance that is in the container provided with the screw cap could be filled into a mixer or a portioning system, wherein an unintentionally falling into the mixer guarantee band can lead to significant malfunction.
  • a guarantee strip which can be solved by unrolling the Flexbandes of a container neck without the guarantee strip tears from the screw cap, the risk of manipulation of the container contents increased, since then such a state could also be deliberately brought about to replace the container contents and / or change.
  • the present invention is therefore an object of the invention to provide a screw with Flexband, which ensures even with larger tolerance deviations between closure and container neck still a safe tearing off the guarantee strip and thus provides increased reliability.
  • the upper inner edge of the less extensible portions in the folded state of the flex band defines the smallest inner diameter of the flex band, so that this upper inner edge rests against the bottleneck in use below the locking ring.
  • the less easily stretchable portions may have radially inwardly projecting projections defining the smallest inner diameter of the folded-over flex band.
  • the radially inwardly projecting projections are provided at the upper free end of the flex band.
  • triangular or nose-shaped projections are preferred, which form the upper end portion of the less easily stretchable portions and have their maximum radial extent at the free end of the flex band.
  • the top of the protrusions then forms part of the surface engaging the underside of a locking ring.
  • the projections can also have largely any, other cross-sectional shapes, for example, rectangular or with more complex, polygonal or rounded outlines can be configured.
  • the more easily expandable sections are formed by sections having a smaller wall cross-section, in particular by sections which, in the folded-over state, have a smaller wall thickness measured in the radial direction than the remaining, less easily stretched sections.
  • These less easily stretchable sections or the sections with the larger wall cross-section have an upwardly widening cross-section, wherein the upper edge of the folded-over Flexband surrounds the most radially inwardly projecting projections.
  • the cross-sections mentioned here are always defined by cross-sectional planes which are defined by the axis of the screw cap and a radius extending from the axis.
  • a Flexbandes distributed over its circumference several easily stretchable sections and between less easily stretchable sections, which also have radially inwardly projecting projections in the folded state is that such a Flexband is even better suited for capturing larger tolerance deviations .
  • a flex band can be designed and manufactured from the outset with a smaller nominal dimension of its inside diameter, this inside diameter of the flex band being the free inside diameter of the flex band, which adjusts itself in the folded-up state of the flex band.
  • this inner diameter is defined by the respective inwardly projecting projections of the less easily stretched sections.
  • the actual wall of the flex band which is through the connection from the hinge portion through the center of the latter, stands outgoing wall portion is defined, still relatively steep and at a very acute angle or nearly parallel to the outer wall of the guarantee strip or to the axis of the closure.
  • the more easily stretched sections ensure that, despite this relatively small inner diameter of the flex band, the same can nevertheless be moved without tearing over the securing ring, which has a significantly larger outside diameter.
  • the radially inwardly projecting projections are designed in such a way that they are comparatively easily deformable and thus additionally facilitate the push-away of the flexible band via the securing ring.
  • the radially outboard wall of the flex band in the folded state defines, after the screw cap is seated to a desired pitch, an approximately tapered circumferential wall portion having a relatively acute cone angle corresponding to the angle between the wall of the flex band and the axial direction ,
  • the radially outer wall of the flex band can additionally have a radially outwardly slightly thickened bead or bead edge at the upper end of the flex band in addition to this cone-shaped circumferential basic shape.
  • the guarantee strip on its inner surface has a corresponding circumferential recess to accommodate this bead.
  • the wall of the flex band extends nearly parallel to the outer portion of the guarantee band or parallel to the axial direction. This position is particularly important for the flex band when it is moved over the circlip and is maximally expanded.
  • the outer wall of the flex band defined in the folded state, a cone wall or a cone wall as an envelope, expediently defined by the conical angle measured towards the axis.
  • a small angle between the conical outer wall of the flex strip and the axis of the screw cap is a good measure and an indication of the functioning of the guarantee strip.
  • the thick-walled portions with the radially inwardly projecting projections in the circumferential direction occupy respectively two to ten times the corresponding peripheral portions of a stretchable or thin-walled portion.
  • a total of nine more easily expandable sections are provided alternately with less extensible sections, the more easily expandable sections each occupying about one fifth of the peripheral sections each occupied by the less easily stretched sections ,
  • the less easily stretchable sections can also be further structured in that, for example, each of the circumferentially lying end portions of the upper edge of the less easily stretchable peripheral portions each have something more pronounced and further radially inwardly projecting nose-shaped projections than the intermediate areas. These end sections, too, can again make up about one-tenth to one-fourth of the corresponding circumferential section.
  • the approximately nose-shaped projections have an approximately triangular basic shape, and set against the inside of an already wedge-shaped wall cross-section of the thicker-walled sections. If one already understands the spline of these sections as compared to the profile of the thin-walled, more easily stretchable sections as a projection in the sense of claim 1, one can also describe the cross-sectional profile of the less easily stretchable sections in a preferred embodiment in that the triangular projections inwardly, ie have in the triangle profile, kinked hypotenuse. This results in the upper end portion of the radially inwardly projecting protrusions being given a somewhat more acute cross section, i. the angle between the top of the flex band, which comprises the top of the nose-shaped projections, and the inside surface of the nose-shaped projections becomes somewhat smaller than without a correspondingly inwardly kinked hypotenuse.
  • the invention is provided for screw caps whose nominal diameter is at least 35 mm, the advantages are even more pronounced when the nominal diameter of the screw cap is larger, that is in particular at least 50 mm.
  • the invention is also directed to the combination of a container and a screw on the container neck screw cap, with a container neck and a molded thereto, the container neck surrounding and flange-like outwardly projecting circlip. outward visibly this combination, the object underlying the invention is achieved in that the screw cap has the features of at least one of claims 1 to 1 1.
  • the inner diameter defined by the less easily stretchable sections of the folded-over flexible band should be smaller than the outer diameter of the bottle neck immediately below the securing ring, which means that after the closure has been applied, the flexband is widened underneath the securing ring through the neck of the bottle is applied and under tension to the bottleneck. Furthermore, it is provided in the preferred variant of such a combination that the outer diameter of the bottle neck tapers below the securing ring and with increasing distance from this securing ring.
