Definitions

  • This invention relates to a method of marking or writing upon a substrate, and subsequently removing the markings when required, and also to apparatus for enabling the method to be put into effect.
  • Erasable marking systems are well known.
  • One such system employs a pen having a solvent-based ink which may be erased by wiping or dabbing with solvent carried on a cloth or pad.
  • the solvent used is often water, for health and safety reasons and because it is readily available.
  • Dry-wipe marking systems using ink formed from a pigment carried in a solvent which evaporates completely after use, are also known. Provided a suitable substrate is used, markings made with a dry-wipe pen may be wiped away without the use of any solvent.
  • GB 2118135 entails writing upon an impermeable substrate label with a pen containing either a water-soluble or a waterproof ink and then wiping the writing away using water or an organic solvent as appropriate.
  • water-soluble ink When water-soluble ink is used for the purpose, the writing may easily be smudged if the labelled tape is handled with damp or sweaty hands.
  • Waterproof inks are less convenient to use in this application than water-soluble inks because the solvent must be dispensed on to a suitable wiping article when it is required to remove the writing and the dispensing, use and subsequent disposal of the solvent can create potential health problems or a fire hazard.
  • a method of erasably marking a substrate and subsequently erasing said marking comprises marking with a waterproof ink on the substrate, said substrate having a surface which is smooth and impermeable to said ink, and subsequently removing said marking by rubbing with a non-abrasive eraser.
  • Apparatus according to the invention for enabling an article to be erasably marked with ink and subsequently erasing said marking comprises a pen containing a waterproof ink, a surface which is smooth, impermeable and able to be marked with said pen and a non-abrasive eraser.
  • the pen preferably delivers "indelible” or waterproof ink and is preferably a felt-tip or fibre-tip pen.
  • suitable commercially available pens include the "STAEDTLER LUMOCOLOR 317", “EDDING 142M” permanent OHP marker and the “BEROL PERMANENT LABELLING PEN” and other similar pens which are sold as permanent, indelible or waterproof marking pens.
  • the substrate which is marked upon has a surface which is smooth and impermeable to the ink used in the pen. That is to say, the surface should not absorb or be etched by any component of the ink to any significant extent.
  • the surface should have physical and chemical properties which enable it to be wetted by and to bond to the ink sufficiently for it to be clearly written upon by the pen.
  • the markings, when dry, should not be easily removable on contact with wet or dry skin.
  • the surface should be selected to bond to the ink sufficiently weakly for the markings to be removable by rubbing with an eraser.
  • the substrate may be transparent, opaque or translucent.
  • the substrate is preferably a plastics film and most preferably is either oriented polypropylene or oriented polyester film or a gloss-finished polyvinyl chloride film.
  • An unfilled high-gloss film may have a surface which is generally smoother than a film which contains particles of a filler material.
  • the non-abrasive eraser is preferably a block eraser of the type sold for erasing pencil markings.
  • Non-abrasive in this context means that the eraser does not abrade the impermeable surface on which the erasable markings are formed to any significant degree. If the permeable surface were to be abraded then ink would be trapped within the small irregularities or scratches on the surface and that ink would be difficult to remove without recourse to wiping with a solvent.
  • One example of a suitable block eraser is the "STAEDTLER MARS PLASTIC ERASER" although many suitable erasers exist, which, typically, are made from vinyl compounds. The eraser may be used dry but for removal of certain markings, especially where the markings are relatively old, it is advantageous to moisten the eraser or the marked surface to achieve a faster, more complete removal of the markings.
  • the impermeable surface which is preferably a plastics film, may form part of a laminate structure.
  • the laminate preferably includes an opaque layer, which may be paper, board or opaque film or a layer of an opaque ink printed upon the under-surface of the impermeable markable substrate, so that writing etc. which is marked on the surface can be clearly seen. It is preferred that where such a laminate and a pen are provided together as a 'kit', the colour of the ink contrasts with that of the opaque layer so that the markings of the pen are clearly visible.
  • the laminate structure may include an adhesive layer on its lower surface so that the surface may be adhered to an article such as a video tape for example, for labelling purposes.
  • the surface may have non-erasable markings upon it such as a border, grid, words or graphics. Those markings may be printed or etched upon the surface or, more preferably where the surface is a clear plastics film, they may be printed on the reverse of the film or on a separate layer located beneath the surface, e.g. on an opaque layer of a laminate structure.
  • the impermeable surface is the upper surface of a clear film laminated to or overlaying an opaque layer, which may be an opaque film, paper or board for example, upon which is printed a grid pattern.
  • the grid is preferably an alphanumeric grid.
  • the grid is preferably printed in reverse i.e. so that the background is relatively dark and the alphanumeric grid lighter in colour.
  • the application of the method and apparatus of the present invention to video cassette cases or sleeves may take different forms, depending in part on the material of which the case or sleeve is made.
  • the whole case or sleeve may be formed as a laminate for marking according to the invention or its spine may bear a laminated label attached to it.
  • the case or sleeve is formed in a plastics material, it may be formed as a whole in the desired impermeable markable material or as a laminate or the material may be adhered in the form of a label.
  • the case or sleeve may be moulded in a suitable plastics material such as polypropylene with one or more areas formed with a gloss surface to receive the identity markings.
  • the markable substrate may be attached to the spine of the case or sleeve by welding, gluing or clips.
  • a further form of the invention comprises one or more laminated sheets of which the top layer is a smooth impermeable clear film and having an opaque layer which is optionally printed with an alphanumeric grid and, preferably, other markings such as a list of numbers.
  • This sheet or sheets may then be used as an index to record information pertaining to the contents of a number of video cassettes.
  • the sheets are adapted to be placed into a binder which is itself adapted to fit neatly into a video cassette sleeve and preferably also adapted to hold a waterproof pen and non-abrasive eraser, for example in a loop or pocket secured to the binder.
  • the binder may then be stored together with the video tapes about which information is contained therein.
  • camcorder and audio cassette labelling Some examples of other suitable uses for this form or any other form of the invention are camcorder and audio cassette labelling, insert cards for tape cassettes, name and address recording systems, e.g. for personal organisers, and computer disk labels.
  • the drawing shows a video cassette 10 partially inserted into a video cassette sleeve 11.
  • the sleeve 11 is made of a cardboard base layer laminated to a top layer of a clear impermeable plastics film. Areas 12 of the cardboard are printed with an alphanumeric grid. The grid is formed in white on a black background so that if a white part of the grid is overwritten in black, that part is no longer clearly visible. The remainder of the cardboard may be printed with an attractive design.
  • a word, words or numerals may be formed so as to indicate the contents of the tape contained within the sleeve.
  • the markings may be removed by rubbing with a non-abrasive eraser and different letters may be formed on the grid by remarking the area 12 with the pen.
  • the sleeve 11 may alternatively simply have a clear area, perhaps surrounded by a decorative border, in which a user may write words or numbers with a waterproof pen.
  • the back spine 13 of the video cassette may itself have a label which is a laminate structure having at its top layer a clear impermeable film. That label preferably comprises an alphanumeric grid printed on an opaque layer of the laminate. The label may then be marked upon and erased in the manner described above.
