Definitions

  • LAMINATED PRODUCT The present invention relates to laminated products, particularly for use as promotional or entertainment devices, and finds particular application in low cost headgear.
  • the card is printed with relevant publicity or advertising material on a surface which will be exposed in use.
  • An example of such products is a simple hat constructed from flat piece of card having a central aperture through which the top of a user's head projects. The hat sits on the user's head in the manner of a hat brim, without a crown.
  • This form of headgear may also be provided with a logo carrier which projects into the central aperture when the hat is out of use but which is bent to stand upright when the hat is in use, by the user's head as it projects through the central aperture, so as to attract attention.
  • Embodiments of the present invention have the advantage that they can be manufactured in large numbers, without excessive cost, and can present a pleasing appearance while being sufficiently robust to withstand considerably rougher and/or longer lasting treatment by a user than has hitherto been possible with a comparable cost product.
  • a laminated object such as a promotional or entertainment device, comprising a foam product having a body of foam and a printed film which is adhered to a surface thereof.
  • the foam may comprise a known polymeric foam. Preferably, it comprises an open cell foam.
  • the printed film may comprise a plastics material such as polyethylene or polypropylene.
  • foam and particularly open cell foam has a mobile structure which makes direct printing very difficult, as well as cutting out of exact predetermined shapes.
  • a feature of the present invention is that the use of an adhered film not only provides a carried for the printing but also stabilises the foam for cutting out.
  • the surface of the film can bemodified, for instanceby flame or coronadischarge treatment.
  • Another problem lies in achieving satisfactory lamination of a film onto the surface of an open cell foam. There is a tendency for the film to wrinkle, or for the relative tensions of film and foam to vary so that the laminated product is warped.
  • the open cell foam to which the printed film is laminated may comprise one of several materials including polyethylene, polyurethane, and polyester, polyethylene foams having been found preferable in terms of cost.
  • the production process comprises in general the surface treatment of polymeric film, particularly polyethylene film, by for instance flame or corona discharge treatment, the application of printing to the film, followed by laminating of the printed film on to a roll of open cell foam in laminating equipment, according generally to a known laminating process.
  • adhesive is applied either to the foam or to the film, any solvent-based adhesive being found suitable, and the film is then applied to the surface of the foam.
  • a thickness of about 7 mm is suitable. This produces a hat which is sufficiently stiff that a portion will stand up so as to be clearly visible when the hat is worn, while the amount of materials used is kept relatively low, thus avoiding extra cost and volume.
  • a foam thickness in the range 5 to 10 mm is preferable, 7 mm having been found to be optimal.
  • the thickness of the film has been found to have a significant effect on the success or otherwise of the laminating process. Although a thin film, of a thickness in the range from 25 to 45 microns has been found satisfactory, it may be found mechanically easier to deal with film a little thicker, for instance up to 100 microns, or more particularly 60 to 70 microns, in the laminating process. This makes it easier to achieve correct alignment between film and foam, and relative tension of the two.
  • Figure 1 shows a plan view of a fun hat made according to an embodiment of the present invention
  • Figure 2 shows a fun hat as shown in Figure 1, in use
  • Figure 3 shows schematically a laminating process for laminating a printed film onto a strip of open cell foam
  • Figure 4 shows a cross section on the line A-A of Figure 1, viewed in the direction indicated by the arrows;
  • Figure 5 shows part of a laminated sheet prior to cutting into fun hats.
  • a fun hat made according to an embodiment of the present invention comprises a flat panel 1 of open celled foam 6 having a printed film 5 on its upper surface.
  • the composite panel 1 has an aperture 2 therein with a scalloped edge.
  • the aperture 2 has a "cut-out" 3 which extends from an edge thereof into the centre of the aperture. When the hat is placed on a user's head, the cut-out 3 is pushed upwards to stand upright in a clearly visible position.
  • the scalloped edge of the aperture 2 is merely to provide grip on the wearer's head, and could be replaced by a smooth-edged aperture or by some other shape such as a toothed profile.
  • the panel 1 of foam must have a certain thickness such that the cut-out 3 will be self-supporting, in use.
  • the open cell foam panel 1 has a thickness of 7 mm.
  • the fun hat is produced using a laminating machine.
  • a roll 4 of open cell foam is fed to a pair 31, 32 of laminating rollers where it meets, and is laminated to, the printed film 33.
  • the printed film 33 is supplied from a roll 30, being fed to the laminating rollers 31, 32 via a tensioning roller 34 and an adhesive applying roller 35.
  • the adhesive covered surface of the printed film is applied to the open cell foam, whereafter the adhesive is cured and the laminated product 38 stamped or cut into multiple fun hats.
  • Laminating processes of this general type are known and elements of the equipment are therefore known.
  • the adhesive applying roller 35 is of known type, having a bath 36 applying adhesive to the surface of the roller 35 and thence to a face of the printed film 33. Conveniently, the adhesive applying roller 35 can be moved away from the printed film 33, for instance, for maintenance, loading and starting up operations.
  • the relative tension between the film 33 and the foam 37 is important. If it is incorrect, the film can tend to wrinkle when applied, or to warp the finished product if it is significantly tighter than the foam in the laminating process.
  • the tension can be adjusted to correct such defects by means of the tensioning roller 34 which is adjustable in the tension it applies.
  • a "banana” roller is used, such rollers having a slightly convex outer surface in cross section, this having the effect of spreading the film 33 outwards towards the edges of the surface of the roller 34 and therefore keeping it flat.
  • Corona discharge treatment has the effect of slightly oxidising the surface of the film, so as to increase the plurality of the surface molecules by forming for instance methyl groups. Such surface modification permits the ink or adhesive to spread more evenly on the surface during a subsequent printing or adhesive application step and also promotes the formation of strong chemical bonds. Both factors give increased adhesion.
  • the film is passed through a high energy electrical corona discharge formed between an electrode and an earthed roller which may or may not be provided with a dielectric cover. Suitable equipment is commercially available and operates from normal mains voltage to generate sufficient power at high frequency to produce a corona discharge.
  • the film surface is subjected to a high energy electrical and ionic bombardment, the intensity of which is usually controlled by adjustment of the electrical flux applied at the electrode. Corona discharge treatment is described and discussed in the following publications:
  • the polyetlylene film is printed for instance by a known technique such as flexography or gravure to produce an image of a selected decoration on one side of the film, and can then be stored in a roll. Subsequently, glue is spread on the non-printed side of the film, which is then adhered to the open cell foam in the laminating process described above.
  • the composite sheet 38 produced must be cut in register with the printed fun hats 50.
  • sets of four fun hats 50 are printed in respective panels 52, each panel 52 being provided with a marker 51.
  • the cutting machine (not shown) detects the marker 51 for each panel 52, each marker 51 being accurately and consistently located with respect to the printed hats 50 of that panel 52. The cutting machine is thus able to align itself in order to cut the fun hat outlines in register with the printing thereof.
  • polyethylene film at a thickness in the range 25 to 45 microns has been found suitable, giving the open cell foam sufficient strength for the decorative cut-out to stand up.
  • film having a thickness in the range 60 to 70 microns is preferable.
  • flexographic ink and the polyethylene film By using the combination of flexographic ink and the polyethylene film, about six different colours can be printed and photographic images can be reproduced thereby.
  • Either high or low density polyethylene films can be used but low density films are preferred. These films can be either clear and transparent, or coloured.
  • An advantageous alternative material for use as the printed film is polypropylene. Although more expensive than polyethylene, it tends to stretch less and is therefore more easy physically to manipulate, for instance during the laminating process.
  • the film used can be printed on either side with respect to the surface to be adhered to the foam. Either it can be reverse printed on the surface to be glued, or it can be positively printed on the surface which will be exposed in the finished product. If it is reverse printed, only one side of the film must be corona discharge treated since one side of the film only receives both ink and adhesive. This makes the printed but unglued film slightly easier to store on a roll since the untreated side of the film does not significantly lift the ink from the printed side. However, if positive printing is used, the number of colour print runs can be reduced for instance where a background colour is to be applied. In reverse printing, the background must be printed on but in positive printing, the film can itself be coloured .
  • a suitable type of ink which does not interfere significantly with the printed film, or the adhesive, and which does not tend to lift off significantly when the printed film is stored in a roll comprises a solventresistant, wax-free laminating ink.
  • a solventresistant, wax-free laminating ink is obtainable under the trade mark "POLARIS" from the Company COLLIE COOK CONSOLIDATED.
  • Products according to embodiments of the present invention are relatively cheap to manufacture, convenient to produce in large quantities, for instance in the order of 10,000 a batch, and are long-lasting while remaining brightly coloured and therefore good promotional material.
