Definitions

  • the invention relates to tinplate packaging and its manufacturing process.
  • the purpose of the present invention is to make available from the consumer a tin can with perfect waterproof and cheaper than the one currently on the market.
  • the product contained in the packaging according to the invention is not critical. This can be a food product or any other oxygen-sensitive product, such as coffee soluble, roasted and ground coffee and powdered milk.
  • Tinplate is a material known to those skilled in the art. he it is iron covered with tin.
  • the present invention overcomes this problem by when glue is deposited in the critical area of the weld.
  • glue used is not critical. It is sufficient that this glue is compatible in the food sector, if we package food and it is hot-melt to then allow the seal to be welded aluminum.
  • the invention also relates to the manufacturing process a package according to the invention, in which a cylindrical body welded in tinplate, the spraying a line of glue inside said body cylindrical in the weld zone at the level of the zone intended to receive a heat-sealed lid, a aluminum cover inside the cylindrical body in the area of the glue line, we turn the body over cylindrical so as to fill the the packaging and a bottom is crimped onto the cylindrical body.
  • the production line includes a spraying system either continuously or discontinuously. Yes we work continuously, we have to plan behind the place of spraying an adhesive recovery panel.
  • the packaging according to the invention (1) comprises a body cylindrical (2) tin, a bottom (3) crimped on said body (2) and a seal (4) heat sealed on the inside of the cylindrical body.
  • a line of glue (7) to avoid any risk leakage of the closure of the lid in the region of said weld.
  • the cover (4) is welded to the interior of the body (2) over a height a: this height is preferably between 2 and 5 mm, so that be sure of the tightness. So we have a packaging allowing good conservation of any product sensitive to oxygen, especially coffee powder or milk powder.
  • Figure 1 shows the cover (4) before the step of welding: this cover has a tongue (5) to facilitate opening. At time use, the consumer pulls on the tab (5) of so as to delaminate said cover. It is also planned a cover (not shown) allowing reclosing of packaging after first opening.
  • hot melt adhesive Any type of hot melt adhesive can be used.
