Definitions

  • the invention relates to the field of rigid packaging or semi-rigid formed by containers, typically body of boxes, closed by crimped lids.
  • the invention relates more specifically to a method of container closure comprising crimping and heat sealing the cover and the body of the box.
  • the crimping includes the formation of a double hook by winding of the edge of the cover and the crimping edge of the body box, double hook obtained by several sets of knobs crimping.
  • the closure of semi-rigid containers i.e. the metal wall thickness is of the order of 0.10 mm up to 0.15 mm, uses either the technique of heat sealing, either by crimping a cover.
  • the problem posed concerns the final quality of containers filled with packaged products as they are delivered to consumers. This final quality is partly linked to the lid and to the crimping of the lid and the box body once filled.
  • a first object of the invention is constituted by a process as defined by claim 1.
  • the heat sealing operation can be after the crimping process, as shown in Figures 1a to 1d, or simultaneously with that of crimping.
  • said inner coating of said container and that of said cover externally comprises a thermoplastic film, the thermoplastic film of said container and that of said cover being heat-sealable.
  • This thermoplastic film can be a polyolefin film from 5 to 50 ⁇ m thick.
  • PP polypropylene
  • one of said interior coatings comprises a thermoplastic film
  • the other of said interior coatings comprises a heat-sealable varnish to said thermoplastic film.
  • said thermoplastic film is a polyolefin and said varnish is a varnish loaded with grains of a thermoplastic material heat sealable with said polyolefin.
  • Said polyolefin can be PP and said varnish can be an epoxy varnish.
  • said container is coated internally with said varnish
  • said cover is coated internally with said polyolefin, but one can also have the reverse, said container being coated internally with said polyolefin, and said cover being coated internally with said varnish.
  • a second object of the invention consists of the packages obtained according to the method of the invention (claim 11).
  • This packaging containing a product to be packaged, formed by a metal container comprising a skirt and a dropped edge, and a metal cover comprising a bowl and a crimping edge, said cover being crimped to said container, is characterized in that the internal coating of said cover is heat sealed to the inner lining of said container.
  • the opposite parts, heat-sealed, of the interior coatings of said cover and of said container terminate in a peripheral meniscus ensuring the joining of said bowl and said skirt.
  • said container and / or said cover are metallic, the thickness of metal being between 0.10 and 0.25 mm.
  • Said metal may be aluminum or aluminum alloys, or steel, the container may be made of a material different from that of the cover.
  • said container can be made of steel and said lid in aluminium.
  • Said internal coating of said container and of said lid can be chosen from films of thermoplastic material, or varnishes containing grains of thermoplastic material.
  • Said inner coating of said container and said inner coating of said lid can both be films of thermoplastic material, preferably films of polyolefin.
  • said interior coating of said container can be a varnish containing grains of thermoplastic material and said interior coating of said cover can be a film of thermoplastic material heat-sealable to said varnish.
  • said film of thermoplastic material has a thickness of 10 to 50 ⁇ m, and said varnish has a thickness of 3 to 15 ⁇ m.
  • the invention relates more particularly to containers of the type box body or trays, with a lid which can be or not with easy opening.
  • the invention in addition to solving all of the problems posed, and which will not be repeated here, also allows expand the technical possibilities of packaging to crimped lids, in particular in the field of clothing mechanics of the cover, and in that of the resistance to corrosion. These possibilities can, for equal performances, allow to reduce the thickness of these covers, and therefore their material cost.
