Definitions

  • the present invention relates to tubes and tubular containers.
  • Containers of this type are used for a range of products, for example perfumes, alcoholic beverages and so on.
  • the containers are normally made of cardboard or paperboard, and may be formed by spirally wrapping plies of material together into a tube, or by forming a suitably shaped blank into a tubular shape.
  • a window is provided so that the contents of the container may be viewed.
  • the present invention seeks to provide a new construction of tube and tubular container.
  • the invention provides a tube or tubular container comprising an inner tubular sleeve and an outer strip of material spirally wound around the sleeve such that the inner sleeve is exposed between the turns of the outer strip.
  • Such a construction is advantageous in that it affords the container designer greater design freedom.
  • the material of the inner sleeve may be different to that of the outer strip, and/or have a different texture, and/or decoration and so on.
  • the inner sleeve may be formed in any convenient manner. Preferably, however, it is formed by spirally winding at least one, inner, strip of material.
  • the invention provides a tube or tubular container comprising at least two spirally wound, inner and outer, strips, a portion of the inner strip being visible between the turns of the outer strip.
  • the inner strip may be dimensioned and wound so that the edges of its adjacent turns are spaced from one another.
  • the winding pitch and the width of the inner strip is such that, when wound, the edges of the strip abut or overlap so as to provide a substantially continuous sleeve. Where they overlap the turns may be bonded together.
  • the turns of the inner strip are preferably joined together by the outer strip wound around them.
  • the outer strip is positioned such that it covers the joint between the turns of inner strip, and the outer strip bonded to the inner strip, for example by a PVA or hot melt adhesive.
  • the amount of the inner sleeve or strip which is exposed between the turns of the outer wound strip will depend on the relative widths of the inner and outer strips, and generally the outer strip will be narrower than the inner strip. The wider the outer strip is made, the less of the inner sleeve or strip will be visible.
  • the outer strip may have straight edges, or a profiled edge if a more fanciful design is sought.
  • the materials or properties of the inner sleeve or strip and the outer strip may be different.
  • both the inner strip or sleeve and the outer strip may be made from the same material, for example a board material.
  • the inner sleeve or strip is made from a plastics material.
  • the inner sleeve or strip is wholly or at least in part transparent or translucent so that the contents of the container can be viewed between the turns of the outer strip, giving the effect of a spiral window in the container.
  • the outer strip is of a board material.
  • the plastics material may be a polyester material, acetate, polyethylene or any other suitable material and it may be coloured or patterned, if desired.
  • PET is an example of a suitable material.
  • the preferred construction is one in which the inner sleeve is formed by winding. From another broad aspect, therefore, the invention provides a method of manufacturing a tube or tubular container comprising winding at least one, inner, strip of material around a mandrel and then winding a second, outer, strip of material around the mandrel such that a portion of the inner strip is visible between the turns of the outer strip.
  • Such a method has the advantage that it can be implemented on standard spiral tube winding machinery.
  • the desired numbers of strips are continuously wound around a mandrel in close succession, and the formed tube drawn off continuously from the mandrel and cut into appropriate lengths.
  • the second strip is fed onto the mandrel such that it covers the joint between consecutive turns of the first strip, and adhesive is coated onto the second strip prior to its application to the first strip.
  • FIG. 1 shows a container in accordance with the invention
  • FIG. 2 shows a detail of the construction of FIG. 1;
  • FIG. 3 illustrates schematically the method of manufacture of the container of FIGS. 1 and 2.
  • a two-ply tubular container 1 comprises a tubular body 2 which comprises an inner sleeve 4 , an outer strip 6 spirally wound about, and bonded to, the sleeve 4 , a top closure e.g a cap 8 and a bottom closure e.g. a cap 10 .
  • the container 1 is shown as containing a bottle 12 , for example a bottle of spirits.
  • the inner sleeve 4 is made from a transparent PET (Polyethylene Terephthalate) and is formed by spiral winding, as will be described further below.
  • the outer strip 6 is made from a board material, for example paperboard or cardboard. The inner sleeve 4 is exposed between the turns of the outer strip 6 , which means that the bottle 12 is visible through a spiral window 14 defined between the turns of the outer strip 6 .
  • the inner sleeve 4 is formed from a strip 16 of PET which is wound about a mandrel 18 (FIG. 3). Adjacent turns 20 , 22 of the PET strip overlap in a joint region 24 .
  • the outer strip 6 is wound around the sleeve 4 so as to cover the joint region 24 , as shown in FIG. 2.
  • a layer of adhesive 26 such as a hot melt adhesive, is applied between the outer strip 6 and the inner strip turns 20 , 22 , to bond the strips 6 , 16 together.
  • the outer strip 6 needs to be wound with the same pitch as the PET strip 16 , but by choosing strips 6 , 16 of appropriate widths, the width of the window 14 can be varied. Furthermore, the shape of the window 14 can be varied by varying the edge profile of the outer strip 6 . Typically the PET strip may be about 130 mm wide and the outer strip 75-100 mm wide.
  • FIG. 3 there is shown schematically the manufacture of the container of FIGS. 1 and 2.
  • the tubular body 2 is made on a conventional spiral winding tube making machine which comprises a mandrel 18 .
  • the PET strip 16 is fed onto the mandrel 18 from a reel (not shown).
  • the outer strip 6 which has been pre-printed, if required, is then fed onto the mandrel 18 , over the PET strip 16 , from a second reel (not shown) such that it covers the joint region 24 between adjacent turns 20 , 22 of the PET strip 16 .
  • the inner surface 28 of the outer strip 6 is coated with a hot melt, or other, adhesive by a suitable applicator, not shown, such that it will bond together the whole structure.
  • the mandrel 18 is stationary and the strips 6 , 16 are pulled onto the mandrel in a conventional manner by a Figure-8 belt which wraps around the mandrel 18 .
  • the belt is angled to the axis of the mandrel so that it pulls the formed tube off the mandrel 18 continuously, whereafter it is cut to the appropriate length.
  • the cut tubes can then have further operations, such as the application of end caps, performed upon them.
  • the inner sleeve 4 need not be of plastics and could be made from a board material. Also, it could be a two or more ply construction, not just a single ply as disclosed. Also, the inner sleeve 4 could be produced in some other way, for example extrusion. It could also be coloured, patterned, embossed or otherwise decorated, for example with holographic images.
  • outer strip 6 may be of another material, e.g metal and plastic foils and may be patterned, embossed, decorated, for example with holographic images, and so on.
  • the inner strip 16 has been shown to have its adjacent turns 20 , 22 overlapping. This is preferred as it makes it more difficult for adhesive to exude into the interior of the tube, which may not be desirable, particularly when packaging foodstuffs. However, this is not essential and the edges of the adjacent turns 20 , 22 may merely abut or indeed be spaced from one another. The latter arrangement has the potential advantage that less material is used. In order to prevent adhesive exuding into the tube, it need not be applied over the complete surface of the outer strip 6 , but may be applied to selected areas only.
  • tubes described herein have application as bodies for tubular containers, they may find other applications as well.
