Definitions

  • the invention relates to a method for producing an at least coated on its outer surface the lid, in particular a painted lid of metal for beverage cans, having at least one Ausgiessöffnuno, being sealed to the outer surface of an at least Ausgiessöffnun g of overlapping closure strip having a she g elfähiaen layer, which optionally formed from a band coated with a sealable material or the like.
  • beverage cans are usually made from one piece tinplate, tin-free steel or aluminum, and after filling with a desired content through a lid, they are also made from the above. Materials closed.
  • a pouring opening is punched into these covers, for example, and covered again with a sealing strip.
  • the cover has a coating with a lacquer layer, for example a phenol epoxy resin, the sealing strips, e.g. from a thin aluminum strip, a coating from a thermoplastic, such as a polyamide.
  • the lid is placed on a preheated under-sealing tool and the sealing strip is sealed around the pouring opening by a likewise heated upper sealing tool by melting the polyamide sealing layer.
  • the inventor has set himself the goal of developing a method of the type mentioned above in which the formation of bubbles is avoided, the shelf life is increased and the adhesive strength from the closure strip to the lid is improved.
  • the sealing strip itself is heated shortly before and outside the sealing process. If the closure strip before the sealing-on of a first coated with a material defendingelfähi g en tape must be od.dgl.herausgeformt, so is within the scope of this invention that the tape od.d g l. shortly before the sealing strip is formed out.
  • the sealing strip or tape must be heated shortly before it is sealed so that the vaporizable and thus bubble-forming substance cannot reappear on the sealing layer. In experiments, a time period of 5 to 15 seconds has proven to be sufficient. Accordingly, the heater should; For example, an infrared radiator can be arranged directly in front of the sealing tool or a device punching out the sealing strip.
  • an aluminum thin strip with a polyamide layer is sealed onto a pouring opening on q .
  • the temperature of the upper sealing tool is 250 ° C, that of the lower 170 ° C.
  • the specific sealing pressure is 2000 N / cm 2 .
  • the aluminum thin strip passes through a convection oven preheated to 170 ° C.
  • preheating the tape within about 10 seconds is sufficient to eliminate blistering.
  • the belt in the preheating oven reaches a temperature of about 115 to 120 ° C.
  • the waiting time between preheating and sealing should not exceed 30 seconds. What duration of the pre-heating and which temperature is selected in a convection oven depends on the P ro- production conditions from. In any case, the limit is set by the tape material itself, since a tape that has been heated at 170 ° C for 1 minute, for example, can no longer be properly sealed.
