Definitions

  • CONTAINER CLOSURE WITH A GUARANTEE RING AND METHOD OF ASSEMBLING SUCH CONTAINER CLOSURE
  • the invention relates to a container closure comprising a base part which extends around a reference axis of the container closure, a cap part which in a closed position covers a mouth/opening of the base part and in an open position leaves the mouth of the base part open, and a tamper evident ring separate from the cap portion and base portion, intended to provide the consumer with visual information as to whether the container closure has already been opened. It also relates to a method of assembling such a container closure.
  • Document WO2015/049066 A1 discloses a container closure of the type mentioned at the outset, in which the guarantee ring is covered by the cap part and base part in the closed position and is only visible through a transparent wall of the cap part.
  • the base, cap and hinge together form an injection molded part that is formed in the open position. This piece is placed in the closed position before the anti-tamper ring is inserted through the opening in the base. After the guarantee ring has found its position, a spout is inserted into the opening and assembled with the base part.
  • a disadvantage of such a closure is the need to use a clear material such as clear polypropylene for the injection molding that forms the base and cap portions. Other materials such as opaque polypropylene or high density polyethylene (HDPE) are excluded.
  • the disadvantage of closure bodies made of polypropylene is the dust that is produced by friction of the manufactured closure bodies on the conveyor belts of the bottling plants. It is also not possible to choose two different materials or two different colors for the base part and the cap part. With a transparent cap portion, the contents of the container are exposed to light through the pouring opening and the bottom of the cap portion, which is undesirable in certain instances.
  • the container closure is necessarily made of at least three separate pieces, especially since the guarantee ring must be mounted through the opening of the base part. It is therefore not possible to provide a range of container closures which provide the consumer with the same visual information as to the pristine condition of the container's contents and at least some models of which are formed from only two separate pieces.
  • the invention is based on the object of making available a container closure of the type mentioned at the outset, which eliminates at least one of the aforementioned disadvantages of the prior art.
  • a container closure with a base part, which runs around a reference axis of the container closure, a cap part, which covers a drinking opening of the container closure in a closed position and leaves the drinking opening of the container closure open in an open position, and a guarantee ring separate from the cap part and base part , which is positively connected to the cap part and hooked to the base part and has a fracture point that breaks when the cap part is opened and causes an irreversible and visible change in the container closure
  • the object is achieved in that the guarantee ring for positive connection with the cap part having an annular ridge that is non-radial from the base portion is covered and extends in an annular groove of an outer wall of the cap portion facing radially outwards.
  • the cap part can optionally be made of an opaque material. Numerous materials and colors can be used. The colors of the cap part and the guarantee ring can be selected to give a desired color contrast, e.g. by complementary colors.
  • the guarantee ring can be placed on the cap part in the closed position by elastic deformation until the annular bead penetrates into the annular groove and the guarantee ring is connected to the base part in the manner of a hook.
  • the anti-tamper ring has an indicator part for hooking to the base part which engages behind a shoulder of the base part, the breaking point being between the bead and the indicator part.
  • the base portion has a peripheral wall enclosing the display portion and a cavity of the base portion. When the cap part is opened and the fracture point is broken, the display part can fall into a lower region of the cavity due to gravity.
  • the wall may have a radially outwardly directed window designed so that the indicator part is not visible through the window prior to rupture of the fracture and only becomes visible through the window after rupture of the fracture in the lower part of the cavity.
  • the display part projects radially outwards and the shoulder radially inwards. There is thus no overlap between the outwardly directed indicator part and the inwardly directed bead, which simplifies axial demolding of the guarantee ring.
  • An additional advantage of this embodiment arises when the cap part is hingedly connected to the base part by at the beginning of the Rotational movement of the cap part from the closed position, the hook-like connection between the display part and the shoulder is not weakened.
  • the base part is connected to the cap part by a hinge.
  • the cap portion may be integrally formed with the hinge and base portion to form a two-piece container closure.
  • the base part can have a base part and an anchor ring which engages in an annular groove of the base part, the anchor ring being formed in one piece with the hinge and the cap part.
  • the container closure then consists of three pieces, which are optionally made of different materials.
  • the point of fracture is preferably located axially between the annular bead and the anchor ring.
  • the indicator part is preferably located axially between the fracture point and the anchor ring.
  • the cavity is preferably located axially between the indicator part and the anchor ring.
  • Anti-tamper ring and base part are preferably on the same side of a transverse plane passing through the annular bead.
  • the hinge can be designed in one piece with the guarantee ring.
  • the base part has a
  • Connection point in particular a thread, for connection to a container neck.
  • fastening means e.g.
  • the base part can have a preferably radially outwardly directed sealing bead in order to ensure a tight connection to the container neck.
  • the base part can have a spout area which forms the drinking opening of the base part.
  • the container closure can have a spout separate from the base part, which forms a spout area and the drinking opening of the container closure, the spout being covered by the cap part in the closed position.
  • the breaking point extends over an angle of preferably more than 90°, preferably more than 180°, around the reference axis of the container closure, and may optionally have breakable webs, a tear-off line or a tear-off band.
  • the cap part has a bottom that closes the opening of the base part.
  • the outer wall of the cap portion tapers from the groove to the bottom.
  • the invention also relates to a method for assembling a container closure according to the invention, wherein the guarantee ring is placed on the cap part in the closed position by elastic deformation until the annular bead penetrates into the annular groove and the guarantee ring is hooked to the base part.

  • the guarantee ring 14 can be made of a plastic, in particular an opaque plastic, preferably with a color that gives a desired color contrast with the closure piece.
  • the closure piece 12 which is shown individually in Figures 3 and 4, comprises a base part 16, a cap part 18 and a hinge 20 which connects the base part 16 to the cap part 18.
  • the hinge 20 is shown here as a snap hinge and enables a pivoting movement of the cap part 18 about a pivot axis which runs perpendicularly to the sectional plane of FIG. Other types of hinges are also applicable.
  • the base member 16, cap member 18 and hinge 20 are molded together in one piece in the open position as seen in Figures 3 and 4.

  • the head piece 12.2 from transparent or opaque polypropylene (PP) and the base piece 12.1 from high density polyethylene (HDPE).
  • PP transparent or opaque polypropylene
  • HDPE high density polyethylene
  • the anchor ring 210 has a curved peripheral wall 46 which extends over an angle of preferably more than 180°, in the example more than 270°, about the reference axis 100 of the container closure 10 .
  • the peripheral wall 46 includes a radially inwardly projecting shoulder 52 which has the same shape and function as the shoulder 52 of the first embodiment and, when assembled, lies radially opposite and with the lower edge portion 42 of the outer wall 34 of the cap member 18 and the upper bearing surface 224 defines a cavity 48 .
  • the guarantee ring 14 is identical to that of the first exemplary embodiment, to which reference is made for a detailed description.
  • the container closure 10 is manufactured as follows.
  • the three pieces 12.1, 12.2, 14 are manufactured separately by injection moulding, with the head piece 12.2 in the open position of figure 13.
  • the cap part 18 is brought into the closed position.
  • the closed head piece 12.2 is placed on the base piece 12.1 until the anchor projection 248 of the anchor ring 210 is seated behind the shoulder 52.
  • the guarantee ring 14 is placed on the cap part 18 by elastic deformation until the annular bead 56 penetrates into the annular groove 54 and creates a positive connection with the cap part 18, while the indicator part 58 partially penetrates into the cavity 48 and the hook area 62 engages behind the shoulder 52 of the peripheral wall 46 of the anchor ring 16, as can be seen in Figures 15 and 16.
  • the cap part 18 can be brought into the closed position, for example be after the open head piece 12.2 has been placed on the base piece 12.1.
  • the guarantee ring 14 can optionally be placed on the open head piece 12.2.
  • the indicator portion 58 is partially in an upper portion of the cavity 48, radially between the peripheral wall 46 and the lower edge portion 42 of the cap portion 18, and partially outside of the cavity 48 so that it is partially in front of the first opening remains radially visible.
  • the fracture point 60 breaks while the bead 56 remains in the groove 54 and the indicator part 58 falls to the bottom of the cavity 48 due to gravity.
  • the indicator part 58 remains in the lower region of the cavity 48 on the upper bearing surface 224 of the anchor ring 210, where it is completely separated from the peripheral wall 46 of the base part 16 is covered. This ensures that the container closure 10 is changed in an irreversible and visible manner.
  • the indicator part 58 remains trapped in the cavity 48 .
  • FIG. 19 and 20 differs from the embodiment of Figures 13 to 18 only in that the peripheral wall of the anchor ring 210 has recesses or windows 346, which may correspond to recesses 446 in the peripheral wall 146 of the base piece 12.1 and through which before separation of fracture 60 (on Figure 19) cavity 58 and after separation of fracture 60 (on Figure 20) indicator part 58 become visible.
  • the outer guarantee ring 12 according to the invention can be applied to a container closure with a closure piece 12 and a spout piece 128, the closure piece 12 having a base part 16 and a cap part 18 which, in the closed position are injected, and the spout 128 is inserted into the closed closure piece 12. It can also be used in a container closure without a hinge, in particular in a so-called push-pull container closure.
