Definitions

  • the invention relates to a method for the pretreatment of a can body made of a metal sheet for a can before filling the can with a filling material according to the preamble of claim 1.
  • Beverage cans are usually made of sheet metal, such as aluminum or tinplate, and are used in particular for filling with carbonated beverages.
  • a beverage can consists of a one- or two-piece can body with a can bottom and a cylindrical can wall as well as a lid folded at the upper edge of the can wall.
  • the can body can be made for example of aluminum or tinplate.
  • the folded lid is usually made of aluminum and has a circumferential scoring line with a riveted metal tab with which a pouring or drinking opening can be produced by piercing into the inner region of the score line.
  • the can body consists of two parts, namely the bottom of the can and a cylindrical wall of the can, which are, for example. Connected by folding.
  • the can wall is integrally formed on the bottom of the can. Both three-piece and two-piece cans are closed after filling with a filling material, such as a carbonated beverage by folding a lid at the top of the can wall.
  • the can body of two-piece cans can be made by various forming processes such as deep drawing and ironing.
  • DRD cans draw and redrawn
  • DWI cans draw and wall ironing
  • a blank is cut out of a metal sheet and formed into a one-piece can body in a combined deep drawing and ironing process.
  • the inside of the can body is usually painted or it is already used for the production of the can body, a metal sheet having at least on one side a polymer coating, for example of PET (polyethylene terephthalate).
  • PET polyethylene terephthalate
  • the outside of the can body is usually painted or printed, usually with a decorative paint or a motif print.
  • a two-piece metal beverage can with a can wall and a profiled bottom integrally connected to the can wall is made of DE 39 30 937 C2 known.
  • the profiled bottom has a dome-shaped domed to the interior of the box central bottom portion, the circular edge region is connected via a frusto-conical inner bottom portion with a frusto-conical outer bottom portion, wherein the outer bottom portion merges at its other end into the cylindrical wall of the can.
  • Process for the production of beverage cans from a metal sheet for example, from JP 04371332-A , of the DE 198 02 953 C2 and the EP 1 109 635 B1 refer to.
  • beverage cans Due to the material stability of the metal sheets used for the production and the design of the cans such beverage cans usually withstand an internal pressure of up to 6 bar.
  • the domed dome of the can bottom forms a safety reserve in the event of overpressure, which ensures that the bottom initially moves axially outward in the central region of the dome and thus increases the internal volume of the can, as a result of which the overpressure that is formed can be reduced before the dome Can burst.
  • deformation of the can bottom also results in "rolling out" of the positioning edge in such a way that the positioning edge moves radially inwards and at the same time axially outward, while the curved dome moves axially outward emotional.
  • the deformation of the bottom of the can causes cracks in the coating or the coating, in particular the polymer coating, inside the can.
  • the optionally aggressive and acidic filling material can cause corrosion on the wall of the can and it can lead to a metal entry into the medium, for example by iron from the tinplate is triggered and diffused into the filling material.
  • the thickness of the metal sheets used to make beverage cans Due to the described deformation of the bottom of the can at an overpressure in the can, which can occur especially in carbonated contents, the desired thickness reduction of Metal sheet limited if excessive deformation of the bottom of the can and thus due to the occurrence of cracks in the paint or the polymer coating of the metal sheet to be avoided.
  • the present invention seeks to provide a method for pretreatment of a can body made of a metal sheet for a can before filling the can with a filling, with a deformation of the bottom of the can with the emergence of an overpressure inside the filled and with a lid sealed can can be prevented.
  • the pretreatment process is intended, in particular, to prevent cracks forming in the coating or the polymer coating or a metal coating of the metal sheet in which the filling material can enter when an overpressure is formed in the interior of the can.
  • a further object of the invention is to disclose a pretreatment method which makes it possible to reduce the thickness of the metal sheet used for the manufacture of the can without excessive overstressing of the can bottom in the event of overpressure inside the can, which in particular outside the tolerable degree of deformation of 1 mm to a maximum of 1.5 mm.
  • the strength of the pressure force is selected so that the bottom of the can at least in the area of the dome and the free edge deformed.
  • free deformation is meant in this case a deformation which is not predetermined by molding tools or other shaping means.
  • a free deformation in this sense arises, for example, when inside the can a predetermined pressure prevails, which leads to a (free) deformation of the can bottom and the trailing edge, without the deformation by molding tools or other shaping means, as for example in the manufacture of the can body used in a ironing, is affected.
  • the compressive force which is introduced before filling the can on the bottom of the can, is dimensioned so that the deformation caused by the pressure force the bottom of the can and the positioning edge at least substantially corresponds to a deformation of the bottom of the can and the adjusting edge, which would set or adjust at an internal pressure, which may occur when the untreated can filled with a carbonated filling material and is closed.
  • the compressive force which is introduced into the can bottom in the pretreatment method according to the invention can be generated for example by introducing a pressurized fluid (for example compressed air) into the interior of the can.
  • a pressurized fluid for example compressed air
  • the pressure transmitted to the bottom of the can is in the range of 1 to 7 bar and in particular between 3 and 6 bar.
  • the pressure force introduced into the can bottom in the pretreatment method according to the invention can also be produced by a punch which is pressed inside the can against the bottom of the can and in particular on the inside of the domed dome.
  • the can bottom is preferably supported from the outside by a radially outer counter bearing, which rests against the outside of the can body in the area of the chime (transition region between the positioning edge and the can wall).
  • the radially outer thrust bearing is suitably designed to be movable.
  • the pretreatment method according to the invention is carried out in an ironing machine.
  • the pretreatment process may be performed immediately after the can body is formed in the ironing machine without having to remove the can body formed in the ironing machine from the machine.
  • the can body is expediently painted and in particular provided with an interior finish. For this is the Can body then taken out of the ironing machine and painted in a painting at least inside and possibly also outside.
  • the free forming produces a stabilization of the bottom of the can, which is achieved by a material hardening. Due to the free deformation of the bottom of the can in the pretreatment process according to the invention, there is no material thinning in the region of the bottom of the can during the forming process. This makes it possible to use for the production of the can body metal sheets with a smaller thickness.
  • Metal sheets e.g. Tinplate or aluminum with a thickness of less than 0.2 mm and preferably between 0.14 and 0.19 mm are used.
  • a round blank is first cut in a known manner from Ronde from a metal sheet, for example.

  • a fluid under pressure p for example, compressed air
  • the pressure p which is introduced into the interior of the can body, between 1 and 7 bar.
