Definitions

  • the invention relates to a device for closing a threaded neck of a container providing tamper-evidence, a container with a threaded neck comprising such a device, and the use of such a device.
  • a large variety of closures for containers is known which attempt to give evidence that the container has been opened or at least has been placed in a condition for opening once it has been filled.
  • IHS induction heat seal
  • the gist of the invention is to provide a two-part device having a plug and a cap, wherein the cap comprises a piece of the front surface which is in mechanical engagement with the cap and the mechanical engagement allows a rotational force to be transmitted from the piece to the plug.
  • the piece of the front surface is connected to the remainder of the front surface by a material weakening.
  • the piece can be rotatably supported in the rotational direction in case the cap is rotated in the closing direction (usually clockwise rotation) and when the cap is rotated in the opening direction (usually anti-clockwise rotation) the piece can be broken from the remainder of the front surface by breaking along the material weakening.
  • the material weakening can transfer a rotational force to the piece and further to the plug during the capping process, whilst in the reverse direction the material weakening can be unsupported and thus breaks on opening due to a friction of the plug on the inner neck of the container.
  • This provides a tamper evident solution to a consumer, both visual and with an audible/physical break.
  • the invention does not require any modification to the neck of the container. Instead, existing outer geometry of containers, especially the neck, can be maintained and most importantly no modifications are required to existing filling equipment. Further, a linerless cap can be provided.
  • the plug can provide a leak-proof seal to the neck of the container.
  • the plug can have a diameter which is wider than a seal usually used to ensure firm and consistent contact is maintained.
  • the container does not have to be manufactured by injection blow moulding (IBM) which is proven to achieve a container having great accuracy and consistency. Further, sealing of an extrusion blow moulded (EBM) container, especially a bottle made of HDPE or a similar material, becomes possible, which especially allows an existing dairy application to remain light-weight.
  • EBM extrusion blow moulded
  • the material is not limited to the application of HDPE but the container can also be manufactured from PET, R- PET, PP, PLA, PS or LDPE.
  • the device can be applied to a wide range of closure applications which require sealing of products and tamper evidence without requiring additional features on the external neck to provide a locating feature for a tamper evidence band to snap over, like existing forms of closures.
  • the invention provides (a) a cap and (b) a plug, wherein the cap comprises a front surface and a skirt surrounding the front surface, wherein the skirt comprises an inner thread for engaging with a thread of the threaded neck of the container, wherein the plug is at least partially arranged inside the skirt, wherein the front surface has an inner piece and an outer piece that surrounds the inner piece, wherein the inner piece is connected to the outer piece by a connection, wherein the connection between the inner piece and the outer piece has a material weakening, wherein the inner piece is in mechanical engagement with the plug, the mechanical engagement allowing a rotational force to be transmitted from the inner piece to the plug.
  • cap encompasses a screw cap or closure made of plastic or metal which is screwed on and off a thread on a neck of a container.
  • the cap can comprise continuous inner threads or lugs.
  • the cap can be adapted to be reclosable together with the plug.
  • the cap can further be adapted to at least partially cover the neck of a container.
  • the cap can be adapted to be an over cap which in use can be positioned over the plug.
  • plug encompasses a plug which can have a top surface and a circumferential projection or plug extending at least partially in a direction transverse to the radial direction of the top surface.
  • the top surface can be adapted to cover an opening at the neck of the container.
  • the circumferential projection which is in use facing the opening of the neck is adapted to be in engagement of the inner and/or outer edge of the opening at the neck of the container.
  • the plug or circumferential projection is adapted to protrude into the neck of the container.
  • the plug can comprise two circumferential projections extending at least partially in a direction transverse to the radial direction of the top surface, one of the two circumferential projections can be adapted to engage at least partially with the inner edge or outer edge of the neck of the container. In case two projections are provided, the other one of the two circumferential projections can be adapted to engage at least partially with the other edge of the neck of the container which is not in engagement with the first of the two projections.
  • the plug can be adapted to be inside the cap.
  • the plug and the cap can be manufactured separately from each other.
  • the plug can have a maximum diameter which is greater than the inner diameter defined by the thread inside the cap.
  • the cap and the plug can be assembled by pushing the outside rim or outer circumference of the plug behind the inner thread of the cap so that the cap and the plug remain together - the plug remains in the cap - to provide a consumer with a single unit once the device is removed from the container.
  • the plug can be designed as a plug seal which is adapted to seal the container, i.e. the opening at the neck of the container.
  • front surface of the cap encompasses a surface which is adapted to at least partially cover the opening at the neck of the container.
  • the front surface can be bigger than the area surrounded by the edge of the opening.
  • the front surface can have a closed surface, but it does not necessarily have to be a closed surface. Holes, gaps and/or windows in the front surface are possible.
  • skirt is a part of the cap which surrounds the front surface and extends in a direction transverse the plane of the front surface.
  • the skirt and the front surface can confine an angle between 50° and 130°, preferably between 60° and 120°, more preferably between 70° and 110°, most preferably between 80° and 100°.

  • the distance between the outer piece and the center of the cap is greater than the distance between the inner piece and the center of the cap.
  • the outer piece can be integrally formed or connected with the skirt. To increase easy handling and in order to reduce sharp edges, the connection between the outer piece and the skirt can be rounded.

  • the plug can be forced by the mechanical engagement to move together with the inner piece when rotated in the closing direction.
  • the inner piece can be held static by the plug by the resistance of the plug against rotating, due to the friction against the inner neck of the container when the cap is rotated in the opening direction in this preferred embodiment.
  • the resistance force of the plug can be specified to be greater than the breaking strength of the material weakening at the connection between inner piece and outer piece, resulting in the connection to be broken as the cap is rotated further.
  • the insertion of the plug can be assisted by an existing rotational application during the filling process which can reduce the top load required to push the seal plug within the neck preventing the requirement for neck support or additional material to strengthen this area.
  • the invention can also be used if the neck of the container has no thread.
  • the cap can, for example, be lifted from the neck with a linear movement.
  • the cap can also be designed as a push-on cap.
  • Each of the relative movements described (purely linear movement, mixed movement with a linear component, in particular tilting or pivoting movement) between the cap and the container can - in addition to or as alternative to the relative rotary movement between the cap and the container - lead to a break between the inner part and the outer part which provides a tamper evidence.
