Definitions

  • This invention relates to apparatus for facilitating the transportation and de-reeling of a reel wound with flexible filamentary material. It is the general practice to transport a reel of flexible filamentary material in a two-part container which has in one of its end walls a hole, or area or weakness readily removable to leave a hole, through which filamentary material can be drawn from the reel whilst it is still housed in the container. With a view to preventing theft of or tampering with the reel it is the custom to secure the two parts of the container together by means of a separately formed detachable locking device, usually a locking device fabricated from steel and operating with a toggle lock on a rim band. Such locking devices are difficult to assemble, are subject to corrosion and are easily mislaid.
  • Plastics containers for medicinal pills having a screw-threaded plastics cap have been proposed in which the cap has an integral resilient lever and the top of the container has a number of circumferentially spaced stops of such a form that, as the cap is screwed on to the container, the resilient lever rides over the stops and, as the cap is unscrewed from the container, a stop is engaged by the lever to prevent further unscrewing of the cap unless the resilient lever is disengaged from the stop.
  • a plastics container of this kind is described in DE-B-2421292.
  • An object of the present invention is to provide a two-part reel container which incorporates improved means for locking together the two parts of the container.
  • the reel container comprises two separately formed parts each having an end wall and, upstanding from the end wall, a circumferentially continuous side wall and one of said parts having in its end wall a hole, or an area of weakness readily removable to leave a hole, for withdrawal of flexible filamentary material from a reel when housed in the container, the two parts being adapted to be secured together by relative rotation of one with respect to the other, characterised in that the two parts carry a spring-loaded pawl and ratchet mechanism, the pawl being pivotally mounted on the side wall of, and separately formed with respect to, one part of the container, the spring being separately formed with respect to the pawl, and the ratchet comprising a plurality of circumferentially spaced recesses extending around at least part of the periphery of the side wall of the other part of the container, the boundary wall of each recess against which the pawl will bear as the two parts are secured together by relative rotation of one with respect to the other being so inclined as to permit the pawl to ride
  • the improved reel container has two important advantages. Firstly, by virtue of the fact that the two parts of the container carry a spring-loaded pawl and ratchet mechanism for locking the parts together, no assembly of a locking device is involved and there is no risk of a locking device being mislaid; the pawl and ratchet can be made of suitable plastics material and so the problem of corrosion need not arise. Secondly, when the two parts of the container are being secured together by rotation of one with respect to the other, the pawl and ratchet mechanism gives an audible indication as the two parts approach the position in which they are fully engaged.
  • the two parts are in screw threaded engagement but, in some circumstances, the two parts may be secured together by means of one or more than one bayonet fitting.
  • Each recess of the ratchet is preferably of approximately triangular shape, two walls of the triangular recess constituting the said boundary walls and the third wall lying on a common circumference of the container with the opposite apex of the triangular recess remote from the pawl.
  • the end of the pawl which engages successively in the recesses of the ratchet as the two parts of the container are screwed together preferably is of complementary shape.
  • the pawl is in the form of a spring-loaded lever pivotally mounted between a pair of guards which project outwardly from the side wall of the part of the container carrying the pawl and which extend substantially parallel to the axis of the container, the pivotal axis of the pawl being substantially normal to a plane containing the axis of the container.
  • the pawl and guards have holes or grooves which, at least when the pawl is engaged in a recess of the ratchet, are in alignment and provide for securing the reel container against tampering by means of a wire and lead seal or by a plastics seal or tie.
  • a multi-start thread is employed.
  • One of the two parts of the container preferably has associated with the or each thread a stop which is engaged by an end of the or a thread of the other part of the container when the two parts are fully screwed together.
  • the part of the container that does not have a hole or area of weakness in its end wall for withdrawal of flexible filamentary material from the container has a boss which upstands from its own end wall and which will be coaxial with the hole or area of weakness when the two parts are screwed together, the boss being of such an external diameter that it will be a tight fit in the bore of the hub of a reel when the reel is housed in the container.
  • the hole through which filamentary material is to be withdrawn may have a detachable plug or cap.
  • the part of the container having the boss upstanding from the end wall constitutes the lower part of the container and generally, but not necessarily, the axial length of this part of the container is substantially shorter than the axial length of the other part.
  • the lower part of the container carries the ratchet of the pawl and ratchet mechanism.
  • the side wall of the lower part may have a plurality of ribs or may otherwise be serrated so that it can be effectively gripped between the feet of an operator whilst the upper part of the container is screwed or unscrewed.
  • each part of the container is a moulded body of thermoplastics material.
  • Suitable thermoplastics materials include polystyrene, polypropylene and acrylonitrile butadiene styrene terpolymer.
  • the ratchet is preferably integrally formed with the part of the container by which it is carried.
  • the pawl is preferably also of moulded thermoplastics material.
  • the two-part reel container comprises a lower part 1 of moulded thermoplastics material having an end wall 2 and an upstanding, circumferentially continuous side wall 3 and, in screw threaded engagement with the lower part, and upper part 21 of moulded thermoplastics material having an end wall 22 and an upstanding, circumferentially continuous side wall 23.
  • Screw threaded engagement between the lower part 1 and the upper part 21 is effected by means of a multi-start thread 18, each thread on the lower part having associated with it a stop which is engaged by an end of a thread of the upper part when the two parts are fully screwed together.
  • a ratchet 4 comprising a plurality of circumferentially spaced recesses 5 and pivotally mounted on the side wall 23 of the upper part 21 between a pair of guards 25 is a pawl 24 spring-loaded by means of a spring 26.
  • Each recess 5 of the ratchet 4 is of approximately triangular shape, the boundary wall 6 of each recess against which the pawl 24 will bear as the parts 1 and 21 are screwed together being so inclined as to permit the pawl to ride over the boundary wall against the action of the spring 26 into the next recess and the boundary wall 7 of each recess being of such a shape as to form an abutment which prevents the two parts from being unscrewed unless the pawl is manually disengaged from the recess against the action of the spring.
  • the guards 25 have holes 27 and the pawl 24 has a groove 28 and, when the pawl is engaged in a recess 5 of the ratchet 4, the holes and groove are in alignment and provide for sealing the reel container against tampering by means of a wire and lead seal or by a plastics seal or tie.
  • the lower part 1 has upstanding from its end wall 2 a tubular boss 8 which is of such an external diameter that it will be a tight fit in the bore of the hub of a reel when the reel is housed in the container.
  • the upper part 21 has in its end wall 22 a central hole 29 which is coaxial with the tubular boss 8 and through which wire from a reel housed in the container can be drawn.
  • the side wall 3 of the lower part 1 has a multiplicity of ribs 9 so that the lower part can be effectively gripped between the feet of an operator whilst the upper part 21 is screwed or unscrewed from the lower part.
