Definitions

  • the invention relates to a guarantee closure for containers, such as bottles and the like, with a plastic screw cap designed as a screw cap, the jacket of which is connected in the region of the inner circumference of the jacket via tear-off webs with a guarantee tape which carries at least one holding member on its inside, which contributes to the cap screwed onto the container mouth engages under an annular locking projection of the container arranged below the container screw thread, the guarantee band having at least one predetermined breaking point over its circumference, which is formed by a slot in the guarantee band body, which is bridged by a band section connecting the guarantee band (EP-A- 03 29 640).
  • Such guarantee tapes which can be mechanically anchored to the container have the advantage over heat-shrinkable guarantee tapes, for example known from DE-A-32 45 820, that the anchoring process for the guarantee tape and thus also the application device in question are simplified. It is sufficient if they are pushed over the locking projection when the screw cap is screwed on for the first time because they can snap under the locking projection due to their elasticity, the holding element possibly bending upwards and remaining in this position. After the retaining element of the guarantee band has snapped into place, the closure cap can only be unscrewed again by destroying the guarantee band, which indicates the first opening of the container.
  • the inside of the guarantee bands are provided with several holding fingers, for example.
  • the band section connecting the guarantee band ends is web-shaped and extends in the extension of the band ends.
  • the tearing of the tape begins when the closure cap is unscrewed for the first time at the vertical predetermined breaking point of the tape, the connecting section thereof tears.
  • guarantee tapes are sometimes not flexible enough, particularly as a result of manufacturing tolerances of the closure cap and the container mouth, in order to ensure flawless demolding in the manufacture of the closure cap and damage-free application to the container.
  • the guarantee tape will tear prematurely at the predetermined breaking point if it is pushed under stretch over the annular locking projection of the container, which the holding members then engage under.
  • the invention aims to provide a guarantee closure of the type specified in the introduction, in which the risk of premature and unintentional tearing of the guarantee band is avoided.
  • the guarantee closure according to the invention is characterized in that the slot in the guarantee band body passes from the upper to the lower body edge and the band section connecting the guarantee band projects essentially radially outward from the circumference of the band in the form of a loop.
  • the closure cap 1 is screwed onto a container mouth 4 designed according to the MCA standard carries on its outside a screw thread 5 and below it is equipped with an annular locking projection 6 designed as a bead, the outside diameter of which is about 28 mm according to the MCA standard.
  • a guarantee tape 8 is attached via a series of vertical, tearable webs 7, which is made in one piece with the cap.
  • the webs 7 and the upper section of the guarantee band have essentially the same or slightly larger inner diameter as the jacket 2.
  • the guarantee band 8 has on its outer side an outer wall section 9 which widens conically downward from the webs 7 and an adjoining cylindrical outer wall section 10.
  • the guarantee band 8 On its inside, the guarantee band 8 is provided with a circumferential recess 11 which is delimited by an upper wall section 12 which widens conically outwards and downwards from the inner wall of the guarantee band in the example shown and a cylindrical lower wall section 13 adjoining this.
  • the peripheral recess 11 is thus open towards the lower end of the guarantee band.
  • a plurality of holding fingers 14 project inwards distributed over the circumference of the band, which engage under the locking projection 6 of the container when the closure cap is screwed on (FIG. 1).
  • the guarantee band also has at least one vertical predetermined breaking point, which is shown in the right half of FIG. 1 and in FIG. 2 and is formed by a slot 15 extending from the upper to the lower edge of the guarantee band.
  • the guarantee band ends delimiting the slot are connected by an essentially loop-shaped band section 16 bridging the slot 15, which projects radially outward from the band circumference.
  • This connecting section of the guarantee band extends, as shown in FIG. 1, over part of the band height.
  • the tamper-evident strip 8 When the cap 1 is attached to the container mouth, the tamper-evident strip 8 is in transition over annular locking projection of the container, which is designed according to the MCA standard as an annular bead, radially stretched. This deformation is absorbed elastically by the loop-shaped guarantee band piece 16, as a result of which unintentional premature tearing of the guarantee band is avoided.
  • the size of the loop is dimensioned such that the loop is essentially stretched at the height of the largest outer diameter of the annular locking projection.
  • the connecting band section 16 projecting radially outward from the guarantee band can originate from the outside of the guarantee band, as in the exemplary embodiment shown, or from the inner edges of the slot 15. It is understood that the development length of the loop is greater than the mutual distance between the edges of the undeformed slot is.
