Definitions

  • Sweet shops normally stock boiled sweets, toffies and the like in large jars.
  • glass jars with metal or rigid plastic screw caps have been used.
  • the only change that has taken place in recent years is that the glass jars and metal caps are being replaced by jars and caps of plastics material one advnatage of which is that the plastics jars are non-retumable.
  • the complete closure comprises a retaining band combined with a screw cap characterised by the provision of a discontinuous preferably internal screw thread on the cap for engagement with a discontinuous preferably external screw thread around the mouth of the container, the contour of the screw-threads being such that when the complete closure is being screwed on to the container substantially straight surfaces abut against one another but if an attempt be made to unscrew the complete closure sloping surfaces abut against one another, the resistance of the retaining band being sufficient to cause the sloping surfaces on the cap simply to slip off the sloping surfaces on the container so that the closure goes round and round but does not come off.
  • FIG. 1 is a diagrammatic view of a neck profile of a sweetmeat jar embodying the invention.
  • FIG. 2 is a diagrammatic plan view of the jar.
  • FIG. 3 is a side view partly in section of a cap for use with the jar illustrated in FIGS. 1 and 2.
  • FIG. 4 is an underneath plan view of the cap.
  • FIG. 5 is an enlarged section on the lines Y Y of FIG. 4, and
  • FIG. 6 is an enlarged section on the lines X X of FIG. 4.
  • a jar 1 has a neck 2 and a mouth 3.
  • the neck 2 has a discontinuous external screw thread 4 with sloping upper surfaces 5 and straight lower surfaces 6.
  • the thread illustrated on the neck 2 is made discontinuous by the provision of four breaks or gaps which can be seen clearly in the plan view FIG. 2, the four thread sections being indicated by B and the four gaps by A so that we have what is called a four start thread.
  • the jar 1 has an external annular bead 7 below which a tear-band on the closure seats when the closure is in position.
  • the tearband seats on an elbow shaped part 20 of the jar which is shaped as shown to ensure that the tear-band is a snug fit around the neck of the jar.
  • a closure 8 has cap part 9 and a retaining band 10.
  • the cap part 9 has a top 11 and a skirt l2 and the skirt 12 has an internal discontinuous screw thread 13 with straight upper parts 14 for co-operation with the lower surfaces 6 on the jar l and with sloping lower parts 15 for co-operation with the upper surfaces 5 on the jar.
  • the tear-band 10 is connected to the cap part 9 by an annular weakened line 16 and a second weakened line 17 runs out towards the bottom of the band 10.
  • An internal annular projection 18 is provided to seat under the bead 7 on the jar.
  • the jar is filled and the closure may then be screwed on to the jar with the upper surfaces 14 on the cap part 9 of the closure 8 engaging with the lower surfaces 6 on the jar l.
  • closure 8 may be hand fitted by simple downward pressure provided that the closure 8 is orientated so that the threads on the cap coincide with the gaps A in the thread on the jar.
  • the cap part of the closure has an internal annular fillet 19 to seat around the outside of the mouth 3.
  • the invention has been particularly described with reference to sweetmeat containers it is understood that the invention is suitable for many alternative applications e.g. pharmaceutical, cosmetic, chemical and engineering. Also, when pressing a closure into position on a container, orientation of the threads on the cap to coincide with the gaps on the thread on the container is not necessary since the cap will snap into position whatever the relative thread positions.
  • a container and closure assembly in which the complete closure comprises a retaining band combined with a screw cap characterised by the provision of a discontinuous screw thread on the cap for engagement with a discontinuous screw thread around the mouth of the container, the contour of the screw-threads being such that if an attempt be made to unscrew the complete closure without first tearing away the retaining band sloping surfaces abut against one another, the resistance of the retaining band being sufficient to cause the sloping surfaces on the cap simply to slip off the sloping surfaces on the container so that the closure goes round and round but does not come off,
  • a container and closure assembly according to claim I wherein the sloping angle of the threads is between 15 and 45 4.
  • a container and closure assembly in which the complete closure comprises a screw cap and a retaining band to be torn away when it is desired to open the container characterised by the provision of a discontinuous external screw thread with sloping upper surfaces and straight lower surfaces around the mouth of the container for engagement by a discontinuous internal screw thread with straight upper surfaces and straight lower surfaces provided on the screw cap, the arrangement being such that when the complete closure is being screwed on to the container there is an interlocking action between the screw threads but if an attempt be made to unscrew the complete closure there is a sliding action and the closure simply goes round and round but does not come off the container.
