Definitions

  • the present invention relates to a captive closure, comprising a screw cap with a guarantee band, which has at least one cylindrical cap shell with an internal thread and a circumferential guarantee band at the lower, open end of the cap shell, which is connected to the lower edge of the cap shell along easily tearable weakening lines, wherein the guarantee band remains permanently connected to the cap shell via retaining bands after tearing along the weakening lines, wherein the closure is designed for use on an opening nozzle of a cardboard packaging, wherein the closure has a lower closure part with a circumferential flange, which can be connected in a sealed manner to the surface of a cardboard packaging, and a cylindrical pouring spout adjoining the flange, which has an upper outer and a lower inner opening, wherein the closure is further equipped with the screw cap with the internal thread, which can be screwed onto an external thread of the pouring spout, a cutting ring arranged in the pouring spout, which has at least one cutting edge projecting axially inwards on its
  • Plastic products and corresponding plastic waste especially in the form of so-called microplastics, which are formed from plastic waste through abrasion and decomposition, are increasingly the focus of public attention.
  • the screw caps to which the present invention relates are also made of plastic, typically polyethylene or polypropylene.
  • the deposit system which has also been introduced for disposable plastic bottles, does indeed reduce the number of plastic bottles that end up in residual waste and are instead recycled; however, this does not prevent the fact that in many cases the bottle caps are not screwed back on after emptying, but are disposed of separately or thrown away, thus ending up in the environment in an uncontrolled manner and, for example, in the sea on shores and beaches.
  • EP 1 533 240 A1 is a resealable closure for a sealed cardboard packaging.
  • the so-called guarantee bands which are connected to the lower edge of a cap jacket via weak points, remain attached to the container neck below a so-called pilferproof ring and already form a captive part of the closure.
  • the screw cap remains connected to the guarantee band via at least one band section or the like, referred to here as a retaining band, even after the screw cap has been opened and released from the container neck thread.
  • This band is in turn held on the container neck by the so-called pilferproof ring.
  • a pilferproof ring is typically an annular projection running all the way underneath a container neck thread with an essentially flat or slightly conical underside, behind which radially inwardly projecting projections or parts of a guarantee band hook, so that the guarantee band is held in place by the pilferproof ring when a screw cap is unscrewed, while the weak points provided between the guarantee band and the cap jacket tear.
  • connection between the guarantee band and the cap jacket, which remains via at least one retaining band, is long enough to be able to lift the screw cap completely off the container neck opening and to move it sideways or tilt it away from the container neck opening.
  • the present invention is based on the task of designing a captive screw cap with a guarantee band for use on an opening nozzle of a cardboard packaging in such a way that the screw cap, after being unscrewed and loosened, can be folded away or tilted into a position that does not interfere with further use of the cardboard packaging and drinking or pouring from the cardboard packaging and can remain there without additional measures.
  • the screw cap is also referred to here as "cap" for short.
  • retaining bands are formed by two weakening lines, each interrupted at least once in the circumferential direction, which run at an axial distance from one another and partially overlap each other in the circumferential direction, with interrupted sections of both weakening lines being bridged by the other weakening line at an axial distance.
  • the weakening lines can be produced by cuts or by dividing lines with webs already formed in the injection molding tool.
  • the aforementioned interrupted sections of the weakening lines are referred to below as "separating webs".
  • the separating web of the upper weakening line effectively forms an axial extension of the cylindrical cap shell that is limited to a circumferential sector.
  • the separating web of the lower weakening line forms an axial extension of a lower guarantee band section that is held stationary on the lower part of the closure.
  • the term "guarantee band” refers to all sections on the lower edge of a closure cap jacket which lie axially below or beyond the level of the line of weakness from the cap thread, which corresponds to the line referred to here as the upper line of weakness.
  • “Axially below” here also includes the inward and upward angled section of a so-called flex band, which, when manufacturing the closure cap, has an axial extension of the outer guarantee band section, even if parts of this angled flexible band section, when folded upwards, can extend on the inside of the cap above the level of the upper weakening line.
  • both separating strips are considered to be part of the guarantee band as long as they are below the level of the upper weakening line, even if the separating strip of the upper weakening line remains firmly connected to the lower edge of the cap jacket and only detaches along the lower weakening line from the parts of the guarantee band that remain stationary on the lower part of the closure.
  • This also applies analogously to the retaining bands, which are also below the level of the upper weakening line when the closure is closed, but do not remain in this position during and after opening.
  • the guarantee band thus defined consists of a part which remains stationary on the closure base and which - apart from rotation - remains immovable relative to the closure base, and of movable parts, such as the retaining bands and the upper separating web, which are movable relative to the stationary part and the closure base when opened, but remain connected to the stationary part.
  • the separating webs have ends in the circumferential direction, which are each connected to one of the ends of the retaining bands across their axial width.
  • the separating webs have at least the same inner radius as the cap shell.
  • the free end face of the upper separating web pointing axially downwards is referred to as the lower edge, while the axial end region of the upper separating web that encompasses the edge is referred to as the "rim”.
  • the sections of the weakening lines that overlap in the circumferential direction define the retaining bands as strip-shaped sections of the guarantee band that run between the weakening lines in the circumferential direction.
  • the cylindrical cap shell with internal thread defines an axis of the closure, and the closure base, onto which a corresponding screw cap is screwed, defines an axis of the closure base. When closed, these axes coincide.
  • a sufficient axial distance between the weakening lines of, for example, at least 2 mm in their overlap area leads to sufficiently strong retaining straps that do not tear up to a tensile force of 30 N and generally up to 40 N.
  • a tensile force of 30 N and generally up to 40 N For an average consumer and it is therefore not possible for children in particular to tear the screw cap off the part of the guarantee band held under the pilferproof ring by tearing the retaining bands. This means that the cap, including the guarantee band, remains permanently connected to the lower part of the closure.
  • Each of the two weakening lines expediently has exactly one separating web and the centers of the two separating webs are diametrically opposite each other.
  • the weakening lines are at an axial distance from each other in their overlapping areas.
  • the two weakening lines remain in the same axial position along their entire circumferential extent in the unopened closure, but the axial position between the two weakening lines is different.
  • the axial position of the weakening lines can, however, also vary along their course in the circumferential direction, as long as this does not make the retaining bands too narrow and they retain a sufficient tear resistance of at least 30 N to preferably at least 40 N.
  • the upper weakening line defines a dividing line between the lower edge of the cap jacket and the tamper evident band.
  • the lower weakening line divides the tamper evident band along a circumferential section into a lower and an upper tamper evident band section, whereby the upper tamper evident band section is firmly connected to the cap jacket in the area of the interruption of the upper weakening line and otherwise defines a section of the dividing line between the retaining bands and the lower tamper evident band section.
  • the guarantee band is a so-called flexible band, which has a first outer guarantee band part running in axial extension of the cylindrical cap shell and a second guarantee band part running radially inwards and towards The guarantee band part is folded over at the top and the free, upward-facing end of the guarantee band has engagement elements for engagement with the underside of the pilferproof ring.
  • top and bottom are used here as they arise when the closure is oriented onto the container neck opening of a vertically standing container.
  • the separation of the guarantee band along the entire length of the weakening lines results in strip-shaped sections of the guarantee band being created in the overlapping area of the weakening lines due to their axial distance, which are referred to here as retaining bands.
  • These retaining bands connect the respective separating webs of the upper and lower weakening lines, whereby these separating webs in turn form a connection to the cap jacket or to the first guarantee band part, which is intended to remain stationary on a closure bottom part.
  • the separating web of the lower weakening line is a determining factor for the length of the retaining bands, but has no other function with regard to the stability of the open cap position.
  • the separating web of the upper weakening line contributes significantly to stabilizing a wide-open state of the cap, depending on its design. Where the "separating web” is mentioned below without further identification, this upper separating web is always meant. This separating web forms an axial extension of the cap shell and is firmly connected to it.
  • the ends of this separating web in the circumferential direction are each connected to one of the ends of the retaining straps.
  • the other end of the retaining straps is each connected to the ends of the lower separating web in the circumferential direction
  • the cap After unscrewing and then folding away or over the screw cap, which remains connected to the lower part of the closure via the separating bars and the retaining straps, the cap, after a pivoting movement of approx. 90 °, comes into a position in which the lower edge of the separating bar pivoted with the cap is moved radially inwards towards the lower part of the closure and the upper edge of the separating bar, immediately adjacent to the cap jacket, is moved radially outwards away from the lower part of the closure.
  • the retaining straps between the two separating bars are twisted and hold the cap, or the separating bar that axially extends the cap, in contact with the lower part of the closure.
  • the lower edge of the separating bar or its lower edge is in contact with the lower part of the closure and forms a pivot point on the lower part of the closure, which, however, moves in the axial direction during the pivoting movement on the lower part of the closure.
  • the guarantee band initially does not offer any significant resistance during the folding movement of the screw cap and the radial pivoting of the lower edge of the separating strip towards the lower part of the closure.
  • the sections of the retaining straps immediately at the upper end of the divider are stretched slightly more than the sections at the lower end of the divider.
  • the axial height of the divider between the pivot point and the upper attachment of the retaining straps therefore forms a lever for the pulling force of the retaining straps, which assists the further opening movement of the cap when the pivoting movement passes the dead center at approx. 90°. This allows the cap to reach a stable opening angle of e.g. 140° compared to its initial position.
  • the retaining straps extend over the pilferproof ring with the upper divider, which contributes to the stretching and tensile stress in the retaining straps.
  • the retaining bands i.e. the length of the overlapping areas of the two weakening lines, and also the axial height and circumferential length of the separating web are designed in such a way that the stretching of the bands remains in the elastic range and does not reach the yield point.
  • the elastic restoring forces due to the torsion of these retaining bands are relatively low compared to the force which the retaining bands exert on the upper separating bar in the direction of the lower part of the closure.
  • the folded-over position of the closure reached after overcoming a dead center, remains essentially stable and the screw cap does not move in a disturbing manner in front of or too close to the opening of the lower part of the closure.
  • the axis of the closure cap which coincides with the axis of the closure base when the closure is closed, should assume a stable position after opening and folding to the side, in which it is pivoted by at least 120 degrees, preferably by at least 140°, relative to the starting position or relative to the axis of the closure base.
  • each line of weakness it is advisable, although not essential, for each line of weakness to have exactly one separating strip and for the centre points of the separating strips to be diametrically opposite one another.
  • the separating strip of the lower line of weakness which is firmly connected to the rest of the guarantee band, limits the overlap between the upper and lower lines of weakness in one direction and the overlap of the lines of weakness determines the length of the retaining strips that connect the guarantee band remaining on the lower part of the closure to the screw cap casing.
  • the separating bar of the upper weakening line expediently extends over a circumferential angle between 10° and 75°, preferably in the range between 20" and 60°.
  • An angle in this range ensures that the separating bar is stable in itself and is folded over together with the cap jacket and that when opened not only the cap jacket is bent over against the separating bar, and on the other hand this also ensures sufficient force, which holds the folded-over closure in its fully open position, for which the divider must have a certain minimum length in the circumferential direction.
  • the separating web of the lower weakening line which is diametrically opposite the separating web of the upper weakening line, can extend over a circumferential angle between e.g. 120° and 200°, preferably between 170° and 190°, wherein the difference between the circumferential angles of the upper and lower separating webs defines the length of the retaining bands which extend between the remaining part of the guarantee band and the cap jacket.
  • the width of the separating strip remaining on the cap jacket should preferably be at least half the width of the entire intact guarantee strip, i.e. not yet separated along the weakening lines, so that the torsion of this relatively wide section compared to the rest of the guarantee strip causes a corresponding difference in diameter and length between the radially inner, lower edge of the separating strip and the upper edge of the separating strip attached to the screw cap.
  • the width (in the intact state) measured in the axial direction of the separating web remaining on the cap jacket should be at least 1.5 mm, preferably at least 2 mm and in particular about 3 mm or more.
  • the wall thickness of the guarantee band is in a range between 0.3 and 0.8 mm, so it is clear that the forces caused in the band by twisting the separating web relative to the rest of the band are caused, among other things, by the different inner and outer radii of the twisted guarantee band sections (consisting of the retaining bands and the upper separating web), which is greater the wider the twisted section is.
  • the minimum width of the retaining straps measured in the axial direction depends, among other things, on the specific plastic material used and also on the wall thickness of the retaining straps.
  • the minimum distance between the weakening lines, which defines the minimum width of the retaining straps, should therefore be greater than 1 mm, preferably greater than 2 mm and in particular greater than 2.3 mm in one embodiment.
  • An upper limit is determined in each case by the width of the guarantee strip.
  • the retaining straps which are effectively formed as the sections of the guarantee strip running between the dividing lines, then have sufficient tear resistance to prevent the screw cap from being forcibly torn off the guarantee strip - at least by children's hands.
  • the retaining straps are preferably tear-resistant up to a tensile force of at least 30 N, preferably at least 40 N.
  • the combination according to the invention of a closure base with an external thread and a closure is characterized in that the external diameter of the closure base above a pilfer-proof ring, the internal diameter of the guarantee band, as well as the width, the circumferential extent and any thickening of the upper separating strip are coordinated with one another in such a way that after loosening and when the screw cap is subsequently folded over, the free lower edge of the separating strip engages with the closure base.
  • the retaining strips are twisted slightly in the process. When a tilt angle of approx.
  • the cap with the separating strip is moved past a dead center so that the outside of the separating strip then faces the outside of the closure base and the screw cap is stabilized in this position folded over by more than 90° due to a certain tension of the retaining strips.
  • the tilt or folding angle is defined here as the angle between the axis of the shutter base (which coincides with the shutter axis when the shutter base is closed by the shutter) and the shutter axis in the folded state.
  • the difference between the outer diameter of the lower part of the closure in an area above the pilferproof ring, in which the upper separating bar of the guarantee band is arranged on the lower part of the closure after the closure has been opened, should be no more than 2.5 mm, preferably no more than 1.5 mm, smaller than the nominal inner diameter of the guarantee band.
  • the "nominal inner diameter” refers to the inner diameter of the guarantee band without any flexible band section, which in particular also corresponds to the inner diameter of the cap in the area of the upper separating bar before the weakening lines are cut open.
  • tamper-evident band must be secured to the closure base in such a way that it is practically impossible to remove it from the closure base without damage. On the other hand, it must also withstand the forces when the closure is placed on a thread, particularly when it is moved over the pilfer-proof ring. These conditions can no longer be met if essential parts of the tamper-evident band are axially shorter than, for example, 2 mm (apart from easily breakable bridges that may be distributed along a line of weakness).
  • the closure part below the cap jacket is additionally divided into the elements stationary part, retaining straps and separating bars
  • both dimensions are in the range of 2 - 3 mm.
  • an axial width of about 2 - 3 mm remains for the stationary outer guarantee band section. Any axial variation in the course of the weakening lines along their peripheral extension would therefore also be limited to an axial area of a maximum width of 1 mm for practical reasons. This would not change the basic function of a closure according to the invention and is therefore not discussed in detail here.

  • the screw cap has a circumferential guarantee band on the lower edge of its cap jacket, which with an inner projection engages behind a pilfer-proof ring on the outside of the pouring spout below the pouring thread, wherein the guarantee band is partially divided and partially separated from the jacket of the screw cap by two separate, partially circumferential and circumferentially partially overlapping and non-intersecting weakening lines, so that in the circumferentially overlapping areas of the weakening lines, a retaining band is formed from parts of the guarantee band, which holds the screw cap released from the external thread to the lower part of the guarantee band that remains divided at the closure.

  • a line of weakness can generally be a circumferential, uniform weakening of the material, which can be created, for example, by an incision that does not completely penetrate the material of the guarantee band 3 or the transition to the cap jacket 2, or it is an incision that completely penetrates the wall thickness of the guarantee band 3, but which is interrupted at individual points by easily breakable bridges.
  • the closure shown differs from this usual form of screw caps with a guarantee band in that it has two weakening lines 13, 14 which, on the one hand, are spaced apart from one another in the axial direction and, on the other hand, do not extend over the entire circumference of the guarantee band, but are interrupted in an upper separating web 11 of the upper weakening line 13 and in a lower separating web 12 of the lower weakening line 14.

  • the easily breakable bridges 6 tear first and very quickly, which indicates that the closure has been rotated at least once by a small angle in the opening direction, which may be sufficient for the cutting elements to pierce the cardboard material.
  • the length of the retaining straps 15,16 ie the length of the overlapping areas of the weakening lines is according to Figure 4 adjusted so that the lower edge of the upper interruption section 11, when the screw cap 20 is open and folded over by approximately 150°, engages with the outside of the pouring spout 32 and the retaining straps 15, 16 are under tension, so that this position of the screw cap is held by the tension of the retaining straps and the contact of the lower edge of the interruption section 11 with the screw cap 10, even if the pouring spout 32 is tilted in any direction together with the corresponding container.
