Definitions

  • the invention relates to a container closure with a base part which extends around a reference axis of the container closure, a cap part which covers a mouth/opening of the base part in a closed position and leaves the mouth of the base part open in an open position, and a guarantee ring which is separate from the cap part and base part and is intended to give the consumer visible information as to whether the container closure has already been opened. It also relates to a method for assembling such a container closure.
  • a container closure of the type mentioned at the beginning is known 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 part, the cap part and the hinge together form an injection-molded part that is formed in the open position. This piece is brought into the closed position before the guarantee ring is inserted through the opening in the base part. After the guarantee ring has found its position, a pouring piece is inserted into the opening and assembled with the base part.
  • the disadvantage of such a closure is the necessary use of a transparent material such as transparent polypropylene for the injection molded part that forms the base part and the cap part. Other materials such as opaque polypropylene or high-density polyethylene (HDPE) are not possible.
  • the disadvantage of closure bodies made of polypropylene is the dust that is generated by friction between the manufactured closure bodies and the conveyor belts of the filling systems.
  • the container closure is necessarily made from at least three separate pieces, especially since the guarantee ring has to be fitted through the opening in the base part. It is therefore not possible to provide a range of container closures which provide the consumer with the same visible information on the authenticity of the container contents, and at least some models of which are made from only two separate pieces.
  • the invention is based on the object of providing a container closure of the type mentioned at the outset which eliminates at least one of the aforementioned disadvantages of the prior art.
  • the problem is solved in that the guarantee ring has an annular bead for the form-fitting connection to the cap part, which does not protrude radially from the base part. and extends in an annular groove of an outer wall of the cap part, which points radially outwards.
  • the cap part can be made of an opaque material if necessary. Numerous materials and colors can be used. The colors of the cap part and the guarantee ring can be selected to create a desired color contrast, e.g. by using 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 a hook-like manner.
  • the guarantee ring has an indicator part for hook-like connection 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 part preferably has a peripheral wall enclosing the indicator part and a cavity in the base part. When the cap part is opened and the breaking point breaks, the indicator part can fall into a lower region of the cavity due to gravity. If necessary, the wall can have a radially outward-facing window, which is designed in such a way that the indicator part is not visible through the window before the breaking point breaks and only becomes visible through the window after the breaking point breaks in the lower part of the cavity.
  • the indicator part projects radially outwards and the shoulder projects radially inwards. This means that there is no overlap between the outwardly directed indicator part and the inwardly directed bead, which simplifies axial demoulding of the guarantee ring.
  • An additional advantage of this embodiment arises when the cap part is connected to the base part in a hinge-like manner by Rotational movement of the cap part from the closed position does not weaken the hook-like connection between the display part and the shoulder.
  • the base part is connected to the cap part by a hinge.
  • the cap portion may be integrally formed with the hinge and the base portion to form a two-piece container closure.
  • the base part can have a base piece and an anchor ring which engages in an annular groove in the base piece, the anchor ring being formed in one piece with the hinge and the cap part.
  • the container closure then consists of three pieces which may be made from different materials.
  • the breaking point is preferably located axially between the annular bead and the anchor ring.
  • the indicator part is preferably located axially between the breaking point and the anchor ring.
  • the cavity is preferably located axially between the indicator part and the anchor ring.
  • the hinge and the hook-like connection between the guarantee ring and the base part are preferably located on the same side of a transverse plane that runs through the annular bead.
  • the hinge can be formed in one piece with the guarantee ring.
  • the base part has a connection point, in particular a thread, for connection to a container neck.
  • a connection point in particular a thread
  • other fastening means are conceivable, e.g. a circumferential fixing bead or a series of elastic locking hooks that are distributed around the circumference of the base part and, when mounted on the container neck, grip behind a circumferential retaining bead of the container neck.
  • the base part can have a sealing bead that is preferably directed radially outwards to ensure a tight connection to the container neck.
  • the base part may have a pouring area which forms the drinking opening of the base part.
  • the container closure may have a spout separate from the base portion, which forms a pouring area and the drinking opening of the container closure, wherein the spout is covered by the cap portion in the closed position.
  • the break 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 fragile webs, a tear line or a tear band.
  • the cap part has a bottom which closes the opening of the base part.
  • the outer wall of the cap part 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 connected to the base part in a hook-like manner.

  • the closure piece 12 can be made from a plastic or another material that is compatible with the container contents.
  • a polymer is preferred here, in particular a thermoplastic such as polyethylene or polypropylene.
  • opaque materials such as opaque polypropylene or high-density polyethylene (HDPE) can be used here.
  • the guarantee ring 14 can be made from a plastic, in particular an opaque plastic, preferably with a color that results in a desired color contrast with the closure piece.
  • the closure piece 12 which is individually inserted into the 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 is perpendicular to the cutting plane of the Figure 1 Other types of hinges are also applicable.
  • the base part 16 , the cap part 18 and the hinge 20 are cast together in one piece in the open position, as can be seen from the Figures 3 and 4 visible.

  • the sealing skirt 40 can have a circumferential bead or a curvature.
  • the outer wall 34 has a lower cylindrical or slightly conical edge region 42 which, in the closed position of the closure piece 12, rests radially on a cylindrical or slightly conical, radially outward-facing seat surface 44 in a connecting region between the pouring region 28 and the fastening region 22 of the base part 14.
  • the cap part 18 thus encloses the pouring region 28 in the closed position.
  • the edge region 42 and the sealing apron 40 allow, if necessary, a liquid- and gas-tight sealing of the space enclosed by the cap part 18 and base part 14. This is advantageous for the use of the closure for aseptic filling.

  • the indicator part 58 is held by the shoulder 52 and the bead 56 by the groove 54.
  • the break point 60 breaks, while the bead 56 remains in the groove 54 and the indicator part 58 falls into the lower area of the cavity 48 due to gravity.
  • the indicator part 58 remains in the lower region of the cavity 48 on the upper support surface 224 of the anchor ring 210 , where it is completely covered by the peripheral wall 46 of the base part 16. This ensures a permanent and visible change to the container closure 10.
  • the indicator part 58 remains trapped in the cavity 48 .
  • the embodiment of the Figures 19 and 20 differs from the embodiment of the Figures 13 to 18 merely in that the peripheral wall of the anchor ring 210 has recesses or windows 346 , which may correspond with recesses 446 of the peripheral wall 146 of the base piece 12.1 and through which, before the separation of the fracture point 60 (on Figure 19 ) the cavity 58 and after separation of the fracture point 60 (on Figure 20 ) the display part 58 becomes visible.
  • the outer guarantee ring 14 according to the invention can be applied to a container closure with a closure piece 12 and a pouring piece 128, wherein the closure piece 12 has a base part 16 and a cap part 18, which in the closed position and the pouring piece 128 is inserted into the closed closure piece 12. It can also be used with a container closure without a hinge, in particular with a so-called push-pull container closure.
