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 invention relates to a package containing a product and comprising a cylindrical tin body with a welding along a generator of the cylinder, a bottom in tin set with said cylindrical body and a cover aluminum heat sealed on the inside of said body cylindrical to close it, in which the interior of the cylindrical body has in the weld zone at level of the seal a deposit of glue.
  • 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 packaging according to the invention is then provided with a cover covering said cover.
  • the glue deposit is preferably arranged in the form in one stroke, so as to guarantee a deposit of glue in the welding area.
  • 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, we heat seal 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.
  • the size of the boxes is not critical.
  • packaging is envisaged for receiving doses of 50, 100, 200 and 500 g of soluble coffee.
  • You can also package powdered milk, cocoa powder, culinary powder and roasted and ground coffees.
  • One can also consider the packaging of liquid or solid products.
  • FIG. 2 shows the glue spray line.
  • the conveyor belt (10) continuously feeds in the direction arrow A cylindrical bodies (11) welded along a line (12).
  • a spray gun (13) disperses the adhesive (14) on the inside of the cylindrical body (11) according to a line of glue (15) in the area of the weld (12) and near the sealing area of the aluminum seal.
