Definitions

  • the invention relates to a screw cap for closing a container mouth according to the preamble of claim 1.
  • screw caps are usually made in one piece from plastic manufactured by injection molding. But there are also Embodiments known and in use, in which the Screw cap itself z. B. consists of aluminum sheet and that Guarantee tape made of plastic as a separate component with the Screw cap is connected. Especially in the beverage industry such screw caps are used in large numbers. Due to the predefined clock frequencies of filling lines, that run faster and faster means screwing on the Screw caps less and less when closing the bottle Time available. Accordingly, there is a risk that not enough time is available to complete the guarantee band expand slowly when put on, and around the retaining elements of the guarantee band on the complementary Snap tab or bead on the bottle. The consequence is a destruction of the guarantee bands already at Close the bottle.
  • a screw cap is known from the applicant's EP-A-0 459 941 known with a guarantee band, which in addition to the vertical
  • the predetermined breaking point contains at least one relief opening.
  • the relief opening serves to provide the guarantee band for the To make the closing process more elastic.
  • the relief opening is so large must be that the guarantee band is also with the Opening can expand elastically, with which the retaining element in certain cases on the complementary lead on Bottle neck can be raised without the guarantee band tears.
  • the object of the invention is to overcome the disadvantages of the known Avoid, especially a screw cap at the beginning to create the type mentioned, in which the guarantee band at Close the container mouth without damaging the Can break the predetermined breaking point, but when unscrewing for the first time no stretch occurs, which is the guarantee function could affect.
  • This object is achieved according to the invention in a screw cap with the features of the claims solved. So there is above all a relief zone next to the predetermined breaking point of the guarantee band used for bottom of the guarantee band increases in stretchability. This mainly causes that when screwing on if that Guarantee band is expanded from below because restraints - Element and bottle bead meet, the guarantee band progressively expanded with relatively little effort can be.
  • the retention element or the retention elements on the bottle bead hit this causes a stretching or expanding force, starting from the top of the guarantee band. Since the Elasticity through the relief zone in the upper area is less, the guarantee function remains unaffected.
  • the stretching area occurs during stretching and stretching hysteresis a solidification of the material, which is also positive affects the guarantee function.
  • the increase in elasticity can be done z. B. by a reduction in the wall thickness by folding the guarantee band in the area of the relief zone or by means of relief bars different length and / or different Achieve thickness and thus variable extensibility.
  • Relief zones the shape, have proven themselves one widening towards the bottom of the guarantee band Have material dilution that is over a Extend part of the guarantee band.
  • Triangular relief zones have proven their worth, whereby the lower side of the triangle with the underside of the guarantee band coincides and the top of the triangle turns up in Direction extends to the cap. More appropriate The triangle is approximately isosceles and the angle is on the top tip is 25 ° to 50 °, preferably about 35 °.
  • the stretchability of the relief zone should be taken into account the plastic material used is dimensioned so that the stretch of the relief zone after closing of the container is re-formed.
  • a low permanent Overstretching can be tolerated especially if they only in the area of extreme excess, i.e. in the tolerance limit range the container outer diameter occur.
  • the relief zone should be at least over half Extend the height of the guarantee band so that the transition from relatively large elasticity at the bottom of the guarantee band up to "elasticity zero" over a sufficient distance runs.
  • the guarantee band has a circumferential section, along which it is contiguous with the bottom of the Screw cap is connected, it is appropriate if the Relief zone predominantly in the area of the not firmly connected Section next to the predetermined breaking point, in particular in relation to the screw-on direction behind the predetermined breaking point is arranged. If the guarantee band covers the entire Scope is connected to the cap with predetermined breaking bars it is particularly useful if on both sides of the vertical A predetermined breaking point is provided at least one relief zone is.
  • Figure 1 shows a screw cap 1 made of plastic material an internal thread 5, which is intended to a container mouth 2 to be closed with an external thread 6.
  • Screw caps are preferred for closing Bottles of soft drinks are used usually around reusable glass bottles with a standardized Bottle mouth is concerned. You can also use disposable glass and plastic bottles are used.
  • the guarantee band 3 is not under the bead 4 on the bottle neck remains because this is a considerable additional effort for Cleaning the bottle would mean.
  • the recycling of the Plastic bottles are made easier.
  • the guarantee band points therefore an approximately vertical predetermined breaking point in the circumferential direction 11 on, which causes the tamper-evident band from the bottle mouth can be removed and preferably with the Screw cap remains connected.
  • the guarantee band 3 consists of a relatively firm with the lower cap edge connected peripheral portion 9 and out a detachable or not firmly connected complementary section 10.
  • a retaining element arranged in the form of a bead 8
  • the first time Unscrew the cap under the bead 4 on the Container mouth 2 snaps and the first time you unscrew it the necessary pulling force to tear the guarantee tape causes.
  • the guarantee band 3 is by means of webs 20 with the lower edge 18 of the cap 1 connected.
  • the webs 20 tear the first time Open the cap 1 and thus form an approximately horizontal Breaking line.
  • the vertical predetermined breaking point 11 is formed by a upper material web 13 and a lower material web 14, which is arranged at the lower edge 19 of the guarantee band 3 is. In addition to the predetermined breaking point 11 extends from the lower Edge 19 of the guarantee tape 3 up towards Screw cap a relief zone 12.
  • the relief zone 12 is approximately triangular, with the lower side of the triangle coincides with the lower edge 19 of the guarantee band 3. The tip of the triangle points up towards Screw cap 1.
  • the material of the wall is Guarantee band 3 weakened to about a third of the wall thickness. This increases the elasticity without a Tearing in the area of the relief zone 12 would be feared.
  • the guarantee tape 3 has screw caps for commercially available 28 mm bottle caps a total height of approx. 5 to 7 mm.
  • the relief zone 12 extends at least to half the height of the guarantee band. By arranging the relief zone next to the vertical predetermined breaking point 11 is in stretchability increases in this area. Through the triangular Shape is the extensibility in the area of the lower edge 19 of the Guarantee band 3 largest. It takes accordingly Wedge shape of the relief zone according to Figure 1 upwards.
  • the guarantee band 3 stretch enough to tear the material webs 13, 14 during the closing process avoid.
  • the screw cap is opened for the first time, then the top of the bead 8 runs against the bottom of the bead 4 at the container mouth 2.
  • the load on the Guarantee band 3 thus takes place from top to bottom, whereby due to the wedge shape of the relief zone 12 in the upper area there is practically no increased elasticity. Accordingly The guarantee band 3 does not expand and the Bars 20 and the material bars 13 and 14 tear, as in Figure 1 shown.
  • the relief zone is 12 attached to the inside of the guarantee band. she can advantageously be attached to the outside.
  • FIG. 2 shows a modified embodiment of the invention, in which the webs 20 and thus the horizontal Breaking line over the entire circumference, d. H. so 360 ° the Screw cap 1 run.
  • the guarantee tape 3 according to FIG. 2 and 3 is instead of a bead 8 in a known manner provided internally foldable extensions 8a, which as Retaining elements serve and with the bead 4 of the container mouth 2 interact.
  • Figure 4 shows a modified embodiment of a Relief zone 12.
  • the recess 12a is injection-molded in one piece, horizontally extending material bridges 30, 31, 32, 33 bridged.
  • the material bridges 30 to 33 are different thick and of different lengths, so that they are have different strain characteristics during a load.
  • the lowest material bridge 30 is the strongest stretchable so that the protective function for the material webs 13, 14 analogous to Figures 2 and 3 is guaranteed.
  • Figures 5 and 6 show a relief zone 12 with a wedge-shaped running material thinning of the guarantee tape 3 to about 50% of the material thickness.
  • the material thinning runs at an opening angle of about 30 °, the lower side of the relief triangle with the lower edge 19 of guarantee band 3 coincides.
  • FIGS. 7 and 8 show a modified exemplary embodiment, in which instead of the material webs 13 and 14 a thin one Membrane 34 is provided, which is the vertical predetermined breaking point 11 forms.
  • a relief zone 12 is provided, the undulating Has wall sections 12a.
  • the elasticity of the relief zone 12 is again in the area of the lower Edge of the guarantee band 3 strongest.
  • the Relief zone 12 like an accordion, so that the load the membrane 34 is reduced.
  • the optimal arrangement of the relief zone 12 and its Configuration and height mainly depends on the chosen material, the desired extensibility, the dimensioning of the Material webs 13, 14 and the webs 20 from.
  • the arrangement leaves easily optimize in practice.
  • Figures 9 and 10 show an embodiment of a guarantee tape with modified relief zone 12.
  • figure 10 shows the schematic sectional illustration along the line A-A in FIG Figure 9.
  • Figures 9 and 10 according to the embodiment Figure 2 and 3 corresponds to the same parts with the same Provide reference numerals.
  • two relief zones 12 are provided, the one that runs downwards in a wedge shape in cross section Have material dilutions 35. In the top view they are Material dilutions 35 approximately rectangular. Because in the area of Material thinnings 35 the wall thickness of the guarantee tape 3 is thinning downwards and the thinnest point in the The area of the lower edge 19 is reached, the extensibility increases of the guarantee band progressively down, though the Relief zone in the view is not wedge-shaped but about is rectangular in shape.
  • the exemplary embodiments only a vertical predetermined breaking point 11 is shown.
  • the invention can also be used with screw caps be applied, the two or more vertical lines of weakness exhibit.
  • the webs 20 are even in Figures 2 and 3 shown in thick.
