Definitions

  • the present invention relates to a timer for visibly indicating elapsed time and more particularly to a timer for visibly indicating elapsed time in such a manner that, once the timer has been started, it cannot be reset, slowed or otherwise tampered with.
  • the timer according to the invention is capable of a wide variety of different applications, but is particularly useful as a substitute for existing parking meters.
  • a number of prior proposals have been made for substitute parking meters.
  • One example being a timer comprising a case containing a piece of porous sheet material and a reservoir of liquid arranged so that when the liquid reservoir is opened liquid soaks into the paper.
  • the liquid and/or paper being coloured or impregnated with a dye so that the passage of the liquid up or down the paper leaves a visible trace.
  • the device functions as a timer because the progress of the liquid up or down the paper is dependent upon time.
  • DE-C-3717025 discloses a timer device in which an indicating wick material is applied to a base film and is covered by a spacer film on which a mass of indicator paste is then applied. The assembly is finally covered by at least one further film of which an extensive part is transparent. When the reservoir region is compressed to squeeze out the indicator paste along and beyond the spacer film it contacts the indicator strip of wick material to indicate the elapsed time in terms of the length of wick material affected.
  • the method of manufacturing such a timer starts with the base film and involves sequential application of the indicator strips, the spacer film, a further spacer film, the indicator paste, and a transparent cover film.
  • US-A-3954011 discloses a similar laminated assembly in which the indicator material is contained in an absorbent pad and the timing operation is initiated by mechanically removing a spacer film.
  • indicator devices for indicating parameters such as times and/or temperatures are disclosed in AU-B-58880/65, US-A-4229813, AU-B-24467/62, US-A-3520124, US-A-4212153, US-A-4903254, Japan Patent Abstracts Vol. 9 No. 327 (P-415), Patent Abstracts of Japan Vol. 10 No. 389 (P-531), and Patent Abstracts of Japan Vol. 10 No. 106 (P-449).
  • a method of manufacturing a timer for use as an indicator of elapsed time comprising :-
  • the porous wick is paper or a substrate at least partially coated with a porous plastics material (e.g. methylhydroxyethyulcellulose) or plaster of paris.
  • a porous plastics material e.g. methylhydroxyethyulcellulose
  • plaster of paris e.g. methylhydroxyethyulcellulose
  • the rupturable seal is an opening through the film across the bottom section of one of the laminated films and above this is a band of aluminium foil or a line of hot melt adhesive which is bonded to the film.
  • timer device will be described with reference to the production of a parking meter coupon and it is to be appreciated that the same technology can be utilised in other situations.
  • the coupon consists of a porous paper wick 1 encased between a front layer 2 and a centre layer 3 of impervious film material.
  • This covering film material can be a hot melt glue coated or co-extruded polyester film.
  • the layers of film 2 and 3 are laminated together around their periphery. Across the bottom section of the centre film 3 there is an opening such as a slit or holes through the film and above this is a band 4 of aluminium foil, polyester strip or hot melt trace which is bonded by a hot melt glue to the centre film 3 on the wick side.
  • a third film 5 Attached to the back of the centre film 3 is a third film 5 that is sealed around its edges thus forming a cavity between the laminated films 3 and 5. Within this cavity is sealed a volume of fluid 6.
  • the paper wick element 1 is pre-coated on its back surface, facing centre film 3, with a solution consisting of a viscosity correction agent and a dye.
  • the ticket when laminated together is activated by rupturing, pulling, puncturing or positively breaking a seal which is ruptured by movement associated with the generally flexible timer. This rupturing allows the fluid 6 to flow through the slit or holes in the film.
  • VCA viscosity correcting agent
  • the main variable affecting the rate that the fluid front progresses up the paper wick is viscosity variation of the liquid with temperature, thus dissolving of the VCA provides a rate of fluid migration up the paper wick that is comparatively unaffected by temperature variations from environmental conditions.
  • the elapsed time is indicated by the fluid front passing a height indication mark that is printed on the film 2, or paper wick of the ticket. The fluid will continue on past the height mark and hence gives an indication of the time past the expiry time or in this case 'time over parked'.
  • the top flap of the ticket is designed to be folded over a car window and hung on the drivers side window.
  • a method of manufacturing the ticket requires the blotting paper to be coated with the VCA and dye solution, using a direct reverse roller-coating printing operation or similar.
  • the paper may be heated to 160-170°C for a controlled time to modify the VCA's solubility to that required to give a constant viscosity of the fluid as it travels up the paper. This modification is similar to that used in the photographic industry for the hardening of gelatine used in films.
  • the paper wick elements can be cut from a roll of treated paper, then positioned on the film 3.
  • the film 3 is heated to make the adhesive coating slightly tacky, then the wicks ara positioned on the film.
  • This film is then passed between heated rollers or over a heated plate where the top film 2 is laminated to the centre film.
  • the lamination passes between cold soft rubber rollers to 'set' the adhesive.
  • the forming of the back pouch on the ticket, lamination and filling with the fluid is an adaption of standard liquid sachet forming equipment.
  • the preferred version above has been designed to produce particular elapsed times and it is envisaged that by minor modifications and variations the ticket can be designed to provide for differing elapsed times to suit particular users requirements.
