Definitions

  • the present invention relates to closures and in particular, but not exclusively, to closures suitable for attachment to an end of a packaging tube.
  • the present invention also relates to a method and apparatus for attachment of a closure to an end of a tube.
  • Known packaging comprises a 'lay flat' packaging tube, typically made of a plastics material, which is closed at both ends by way of closures in the form of caps or plugs.
  • One known way of attaching a closure to a tube comprises stapling the closure the tube.
  • the present invention seeks to provide an alternative closure, together with an alternative method and apparatus for attachment of a closure to a tube.
  • a closure suitable for attachment to an end of a tube, the closure being provided with a recess in a sidewall, which recess is adapted to receive a depressed portion of the tube.
  • the recess is defined by a radially inwardly located sidewall portion.
  • the recess is bounded by upper and lower walls.
  • the recess is preferably provided at a corner of the closure. Most preferably a recess is provided at at least two corners of the closure.
  • the closure is preferably adapted to be a plug-fit into an end of the tube.
  • a method of closing an end of a tube comprising urging a portion of the tube into a recess provided in a sidewall of a closure.
  • the method preferably comprises urging a portion of a corner of the tube into a respective recess of the closure.
  • the method preferably comprises deforming a portion of the tube into a respective recess.
  • the method comprises urging at least two portions of the tube into respective recesses.
  • the method comprises at least partially severing the tube at a position which is adjacent a portion of tube which is urged into a recess.
  • apparatus for securing a closure to an end of a tube comprising die means which, in use, is adapted to urge a portion of the tube into a recess provided in a sidewall of the closure.
  • the die means comprises cutter means.
  • the cutter means in use, is preferably operative to cut or at least partially sever the tube at a position which is adjacent to that portion of the tube which is urged into the recess.
  • the die means preferably comprises an actuated die head.
  • the die means crimps a portion of the tube into the recess.
  • packaging which comprises a tube, at least one end of which is attached to a closure in accordance with the first aspect of the invention.
  • a closure 1 in the form of a plug, and a packaging tube 2 of flexible plastics material, the closure 1 being urged into an end of the tube 2.
  • the closure 1 is of substantially square outline, the closure comprising a sidewall 3 which is upstanding from a base 4 provided at an axially innermost end of the closure.
  • the base 4 comprises four diagonal ribs 11 which serve to increase the strength of the base.
  • Corner portions 5 of the sidewall 3 comprise two wall portions 7 perpendicular to each other which define respective inwardly located recesses 6.
  • the axially outermost end of the closure 1 comprises a flange 8 which, when viewed in plan, extends beyond the 'footprint' of the closure at by the innermost end of said closure. Those portions of the flange 8 at the corners of the closure 1 define an axially outermost end of each recess 6, and an axially innermost end of each recess being defined by respective corner portions 10.
  • the assembly for securing the closure 1 to the tube 2 comprises four die head assemblies 15, each die head assembly comprising a pneumatic cylinder 16, a piston 17 and a die head 18.
  • each die head comprises a body portion 19 and blade portion 20.
  • the blade portion 20 is of chamfered cross-sectional profile and defines a cutting edge 21.
  • the body portion 19 and the blade portion 20 define two sides which are arranged substantially perpendicular to each other and so form a pointed shape (as best seen in Figure 6).
  • the closure 1 is attached to the tube 2 in the following manner.
  • FIG. 1 shows the closure 1 fully inserted into the tube 2.
  • Handling means conveys the tube 2 and inserted closure 1 to a predetermined position relative to the four die head assemblies 15. Once in position the pneumatic cylinders 16 are activated so causing the die heads 18 and respective pistons 17 towards a respective corner of the tube 2 and the closure 1, as illustrated in Figure 7. The blade portion 20 of each die head 18 comes into contact with the tube 2 so as to pierce that portion of the tube. As each die head 18 progresses further the body portion 19 engages with the tube and urges a portion 2' of the tube 2 into the respective recess 6.
  • Figure 8 shows the die head 18 at the full extent of movement into the recess 6.
  • portion 2' of the tube has been partially severed and deformed through substantially 180°.
  • This frictional engagement ensures that the portion 2' is 'captured' in the recess 6 by what may be termed an interference fit and, as a result, does not inadvertently move or 'spring' out of the recess.
  • folds 20 of the tube 2 act as hinges which aid the process of deformation of the portions 2' into the recesses 6.
  • At least one recess is provided not at a corner of the closure but, for example, is located substantially central of a side of the sidewall 3.
  • At least one recess is provided by a through-hole in the sidewall into which tube material is urged.
  • blade portions 20 may not be chamfered, so as not to define cutting edges 21.
