Definitions

  • the invention relates to a container and closure cap therefor and in particular relates to a container and closure cap of the type in which the cap is screwed onto the container to a predetermined rotational orientation relative thereto.
  • the stop to which such closures are tightened to provide alignment with the container may be either or both of two general configurations.
  • a radial stop on the neck of the container is configured to interact with a cooperating stop, either at the thread tail-out or on the skirt of the closure.
  • the stop is implemented as the lower extremity of the closure skirt comes into the vertical contact with a specially configured (squared off) shoulder on the container. The latter is frequently used to eliminate any unsightly gap between the skirt of the closure and the shoulder of the container.
  • the positioning of the closure against any surface other than the sealing surface creates a variability in the pressure exerted against the sealing surface and results in either over-tightened closures, which are difficult to remove, or loose closures which are not well sealed to the container.
  • the closure may have two or more aligned/stopped positions each corresponding to one of the starts of a multi-start thread.
  • closure orientation may vary by as much as 20 to 100 degrees relative to the container body when screwed on and tightened to a particular sealing force. Conversely, when such closures are screwed on to an orientation stop, the sealing force may vary from zero to an unacceptably high value.
  • closures have been designed to overcome this problem by means of a special sealing feature designed to telescope vertically with a cooperating feature on the container neck, such as tight fitting plug sized to seal the bore of the container neck over a range of depths of insertion.
  • a cooperating feature on the container neck such as tight fitting plug sized to seal the bore of the container neck over a range of depths of insertion.
  • this technique will not work for lack of a smooth controlled diameter on the bottle to seal against.
  • closures have been designed to use a relatively thick gasket resilient through an appropriate range of compressibility to take up the variation and provide sealing pressure within a suitable range.
  • a relatively thin gasket which may be combined with a thin film glued or heat sealed across the mouth of the container to provide tamper evidence, improved barrier properties and reduced cost.
  • the present invention seeks to improve on the prior art and provides a container and closure cap therefor comprising: a container having an open-ended and externally threaded cylindrical neck; a closure cap having an end wall and a cylindrical side wall with an internal screw thread adapted to cooperate with the thread on the container neck; and a flat liner disc located in the cap and adapted to form a seal with the open end of the container neck and having a diameter substantially equal to the internal diameter of the cylindrical side wall, the liner disc consisting of a circular radially inner region and an annular radially outer region; a circular spacing means formed on the end wall of the closure and having the inner region of the liner disc adhered thereto, the spacing means defining an annular recess therearound such that the outer region of the liner disc is spaced from the end wall of the cap; the arrangement being such that the annular region of the liner is deflected resiliently into the annular recess by engagement with the cylindrical neck of the container when the cap is screwed onto the container.
  • the liner disc is deflectected resiliently within its elastic limit and can return to its original flat condition when the closure cap is removed and flex again when the closure is re-applied.
  • a generally rectangular container 1 is shown in Figure 1 having a generally rectangular closure cap 2.
  • the container and cap are of the type in which the cap is intended to be screwed onto the container to a predetermined rotational orientation to form a seal.
  • the container has a body 3 and a cylindrical neck 4 connected to the body by a shoulder 5.
  • the neck has an open end and is provided with an external screw thread 7.
  • the cap 2 has an end wall 8, a rectangular outer wall 9 and a cylindrical inner wall 10 which is provided with an internal screw thread 11.
  • the threads 7 and 11 are adapted to enable the cap to be screwed onto the container so that the open end of the container can form a seal with a thin and stiff flat liner disc 12 which is provided in the cap for this purpose.
  • a circular plinth 13 is formed on the underside of the end wall 8 and is adhered such as by glue to the circular radially inner region 121 of the liner so that the annular radially outer region 122 of the liner disc is held spaced from the end wall of the cap.
  • the plinth 13 defines a recess 14 therearound.
  • the outer region 122 of the liner disc 12 can deflect resiliently into the recess 14. Because the inner region 121 of the liner is glued to the plinth 13 and thus held against bending, the outer region 122 is effectively mounted and deflected in cantilever.
  • Figures 3-5 An alternative embodiment is shown in Figures 3-5 where the plinth is replaced by a plurality of concentric rings 15. This aids cooling of the closure in the mould and also helps liner adhesion since the glue can flow into the gaps between the rings.
  • Figure 4 shows a container and cap where the threads have been positioned such that adequate sealing pressure is established just as the closure reaches an orientation stop on the container. This is a "loosest fit” combination of tolerances and the liner is only very slightly deflected.
  • Figure 5 shows the liner deformation which may occur when specimens having dimensions at the opposite (“tightest fit") extremes are tightened to the same relative orientation.
  • the liner is typically of the type comprising a thin, stiff cardboard liner disc of about 1 - 1.2 mm thickness which carries a thin aluminium membrane (not shown) which can be induction heat sealed or otherwise attached to the open end of the neck 4 in known manner.
  • the cardboard disc becomes separated from the membrane during the heat sealing process. When the container is first opened, the membrane is torn out and discarded but the cardboard disc remains in the cap for re-sealing the container.
  • a liner disc which does not carry on aluminium membrane may be used for applications where this is not required.
  • the diameter of the liner disc 12 is such that it will completely cover the open neck of the container but can nevertheless be placed in position for gluing to the cap without being distorted. Thus it has a diameter substantially equal to the internal diameter of the cylindrical side wall of the closure cap measured at the thread crests. In one example, the diameter of the liner disc is 0.3 mm less than that of the cylindrical side wall.
  • the external diameter of the neck of the container measured at the root of the threads is only slightly less than the internal diameter of the cylindrical side wall so that a good close fit is provided.
  • the diameter of the plinth 13 may be varied according to design and liner material requirements.
  • the angle through which the liner 12 must flex in order to take up the same height variation increases.
  • This changing of the angle through which the liner material flexes causes a proportional change in the force against the sealing lip of the bottle. ie the smaller the angle through which the material has to flex, the lower the force required to flex it, and vice versa.
  • IHS induction heat seal
