Definitions

  • the invention relates to a plastic closure cap, in particular Screw cap, with a guarantee tape according to the generic term of claim 1.
  • Such caps are used to close different Types of bottles or similar containers for One-way or reusable. They are becoming increasingly common in the beverage industry, and that's correspondingly extensive Reservoir of existing technical detailed solutions for execution of the guarantee band and its connection with the .Complete cap. Such caps usually work so that when you first lose weight (Unscrew) the cap of the guarantee tape over a positive locking with the container neck one such large counterforce builds up that the connecting webs to the actual At least partially tear the cap. Hereby indicates that the container has already been opened.
  • caps with guarantee tapes known in addition to the connecting webs acting as predetermined breaking points themselves have at least one predetermined breaking point on their circumference.
  • Such plastic caps are for example in EP 0 552 958 B1 or EP 0 965 533 A1.
  • caps in which the predetermined breaking point on the scope of the guarantee band as through whose wall thickness is formed by a continuous line of weakness is.
  • this applies Line of weakness on the end of a connecting web between Guarantee tape and sealing cap, so that the guarantee tape at Open the container at this point essentially at right angles open and tear off the closure.
  • EP 0 965 533 A1 is the course of the guarantee band predetermined breaking point opposite that through the webs and in between Defined slots between the guarantee tape and the sealing cap Line of weakness inclined. So you get for that first putting on the cap a longer stretch in Guarantee tape circumferential direction in the area of the predetermined breaking point, which improves stability for the first touchdown the cap is secured in the packaging process.
  • the invention is therefore based on the object, a further to provide improved plastic cap, in particular unwanted destruction of the guarantee band in the area the predetermined breaking points even when used on containers certain manufacturing tolerances are practically excluded.
  • the invention includes the basic idea, in scope of the guarantee band compared to known versions when put on more elastic and less prone to breakage Execute predetermined breaking point. It continues to close the thought one, this one starting from the outer circumference, but not through the material thickness of the guarantee tape passing through Weakening. It also closes the thought a, between the guarantee band predetermined breaking point and the Line of weakness between the guarantee band and the actual cap (especially the one between the connecting bars Slots) no direct connection.
  • the contour is the predetermined breaking point of the guarantee band forming recess on the inner contour adapted to the guarantee band.
  • This is special in one widely applicable version of the plastic cap through an annular bead to reach behind a corresponding one (specially ring-shaped) protrusion on the neck of the container. Accordingly, the recess at the level of the annular bead is sufficient here particularly deep into the material of the guarantee tape.
  • their cross-sectional shape is here from a higher and a flatter, on the imaginary undisturbed circumference of the guarantee band lined up trapezoid.
  • the depth of the recess is particularly radial sections greater than half the wall thickness of the guarantee tape. This ensures that the through the recess
  • the predetermined breaking point in the circumferential direction is sufficient is stretchable without breaking. It can therefore be due to stretch windows or similar additional measures to guarantee a high level of break resistance of the guarantee band the first time Put the cap on during product packaging to be dispensed with.
  • the recess extends in a preferred geometric Stripe-shaped design with a substantially constant Width and against the level of the top surface of the closure cap inclined from the free end of the guarantee band towards the actual cap.
  • the one formed by the recess has the shape of one opposite of the container longitudinal axis inclined predetermined breaking line. It runs advantageously in the direction of one end of a connecting web between the cap and the guarantee tape, opens out however - unlike the arrangement according to EP 0 552 958 B1 - not into one of the slots arranged there. Rather is preferably a small distance between the end of the guarantee band predetermined breaking point and the line of weakness between the guarantee band and closure cap provided. This also contributes to Avoidance of guarantee band breaks in the packaging process Occurrence of container or handling tolerances.
  • closure cap includes the line of weakness towards the guarantee band in addition to several narrow connecting bars, each with slots between Limit the cap and the guarantee band, at least one much wider connecting bridge, the width of which is special is about 1.5 to 2 times the length of the slots. In a further preferred embodiment is two such widths Crosspieces are provided around the circumference of the closure cap.
  • the guarantee band predetermined breaking point or line is particular here to one end of the or a wider connecting web directed towards.
  • the closure cap construction described above allows overall a narrower enclosure around the neck of the container (Bottleneck) through the guarantee band.
  • the newly designed The predetermined breaking line is characterized by high elasticity and break resistance out so that they are largely universal for both Glass disposable bottles as well as for PET bottles with BPF mouth or PCO mouth can be used. In particular, it allows an improved compensation of dimensional tolerances sealing containers and of tolerances and force and Effects of vibration during handling in the packaging process.
  • Fig. 1 shows a schematic longitudinal sectional view a section of a plastic screw cap 1 the guarantee tape 3 in the area of a guarantee band predetermined breaking line 5. Indicated is also a line of weakness 7 between the guarantee band 3 and the screw cap base 1a. (The overall structure the screw cap 1 can be seen better in FIG. 3) The longitudinal section shape of the guarantee band 3 is embossed by a projecting annular bead 9 on the inner circumference. in the The area of the predetermined breaking line 5 is in the outer circumference of the guarantee band 3 incorporated the recess 11 shown in FIG.
  • Fig. 3 the plastic screw cap 1 is in an overall view shown, and the course of the weakening line 7 between the screw cap body 1a and the guarantee tape 3 and the guarantee band predetermined breaking line 5 can be seen.
  • the Weakening line 7 includes (not shown here) narrower webs two wider connecting webs between the Screw cap base 1a and the guarantee tape 3, of which 3 the connecting web 15a can be seen.
  • the predetermined breaking line 5 runs from the bottom of the guarantee band below an angle of 20 ° to the longitudinal axis or plane of the screw cap inclined towards the weakening line 7. How can be seen in the representation of detail A, it opens but not in one of the slots 17 in the line of weakness 7 are provided, but ends at a small distance of this. The distance is more common for screw caps Size in the range between 0.2 and 0.4 mm, especially at 0.3 mm.
  • the weakening line 7 consists of a series of slots 17 with narrow connecting webs 19 in between or the wide connecting webs (already mentioned above) 15a, 15b. While the slots 17 through recesses are in the material of the screw cap, are the two Break lines 5 as weaknesses according to the above explanation the wall thickness. In the figure is too recognize that the width of the wide connecting webs 15a, 15b is approximately 1.5 times the length of the slots 17.
  • the narrow connecting webs 19 each have a length of 0.1 to 0.3 times the length of the slots.
  • Fig. 5 shows a cross-sectional representation of a modified Plastic screw cap 1 'at the level of the line of weakness, the the guarantee tape separates from the actual screw cap. It it can be seen that two wide connecting webs 15a ', 15b', which each extend over an angular range of 50 °, and two much narrower connecting webs 19b ', the extend over an angular range of 6 °, and four more narrower connecting webs 19a 'are provided, which are extend over an angular range of 3 °. The between the Crossbars are all slits the same angular range of 29.5 °. As with the arrow in the Figure is indicated, this screw cap 1 'has only one (not recognizable in the figure) predetermined breaking point, the towards one end of one of the two connecting webs 15b ' extends.
  • the implementation of the invention is not limited to this example, but also possible in a number of variations, that are within the scope of professional action.
  • the concrete longitudinal section shape of the recess 11 in the area modified the predetermined breaking point or line 5 of the guarantee tape his.
  • the concrete longitudinal section shape of the recess 11 in the area modified the predetermined breaking point or line 5 of the guarantee tape his.
  • one or two predetermined breaking lines and two wide connecting webs can only be a predetermined breaking line and a wider connecting web is provided his.
  • the concrete form of the Screw cap (according to FIG. 3) are subject to various modifications can.
