Definitions

  • This invention relates to matches.
  • the invention relates to matches incorporating a fire-retardant material such that the match extinguishes itself soon after ignition.
  • Such matches are safer than ordinary matches in that unintentional fires due to the continued burning of the match after the required use are avoided, thus reducing the incidence of, for example, forest fires or injuries to children.
  • a method of manufacturing a match includes the steps of: coating a portion of a porous match splint with a layer of paraffin wax at a temperature such that a substantial part of the paraffin wax remains on the surface of said portion of the splint, coating the splint with a fire-retardant material such that the material does not adhere to said portion of the splint, and coating part of said portion of the splint with paraffin wax at a temperature such that a part of said paraffin wax layer is absorbed into the splint.
  • the splint is suitably coated with paraffin wax by means of a dipping process.
  • a match comprises: a porous match splint having a first portion coated with paraffin wax, a substantial part of the paraffin wax being absorbed into the first portion of the splint; a second portion of the splint coated with paraffin wax, the second portion of the splint containing less absorbed paraffin wax than the first portion of the splint; a third portion of the splint carrying a fire-retardant material; and a quantity of an ignition material carried on the free end of said first portion of the splint.
  • the fire-retardant material is suitably monoammonium phosphate.
  • the match in accordance with the embodiment of the invention comprises a wooden match splint 1 on which is carried a match head 3 of conventional pyrotechnic composition.
  • the match splint 1 is divided into three zones 5,7,9. In the first zone 5, in the region of the head 3, a substantial amount of paraffin wax is absorbed into the splint 1. In the intermediate zone 7, next to the zone 5, a smaller amount of wax is absorbed into the splint 1 than in the first zone 5. Finally, at the end of the match remote from the head 3, the zone 9 is covered in fire-retardant material.
  • the zone 5 is typically 5mms long, with the zone 7 also being typically 5mms long.
  • the match is formed by the following process. Firstly, the match splint 1 is dipped into cold, but molten, paraffin wax so as to coat up to the first 10mm of the splint 1 including the zones 5,7. The whole splint 1, apart from the 6-8mm which is gripped by the match plate, is then coated with fire-retardant material, for example monoammonium phosphate. This material will not adhere to the zones 5,7 of the splint 1 previously coated with wax, thus leaving only zone 9 covered with fire-retardant material, part of the material being absorbed into the zone 9 of the splint 1.
  • fire-retardant material for example monoammonium phosphate
  • the splint 1 is then dipped in a conventional hot paraffin wax bath, so as to coat the 5mms of the splint 1 corresponding to the first zone 5, on top of the cold wax already provided on the splint 1.
  • the hot wax ensures that the paraffin wax in the zone 5 is totally absorbed into the splint 1, conduction of the heat from the hot wax causing a smaller amount of wax in the zone 7 also to be absorbed into the splint 1.
  • the head of the match 3 is then applied to the free end of the zone 5 by conventional means.
  • any suitable flame- retardant material may be incorporated in the region 9, other than monoammonium phosphate.
  • Suitable materials include, diammonium phosphate, ammonium sulphate, and ammonium chloride.
  • any porous match splint may be used, for example cardboard or stiff paper.
