Definitions

  • the present invention relates to a metal vessel having a circumferential side seam, which is formed by lap-bonding of open end portions of upper and lower members by means of an adhesive, the lower member comprising a tall thin wall portion, a thick bottom portion and an open end portion and the upper member comprising a short side wall, a top wall, a spout having a diameter smaller than that of the side wall and an open end portion.
  • EP-A-0 048 890 discloses a metal vessel of the general type with which the invention is concerned, as defined above.
  • So-called draw-ironed cans are widely used for contents having a spontaneous pressure, such as beer and carbonated drinks.
  • draw-ironed cans are prepared by draw-forming a metal blank punched in a disc or the like between the drawing punch and a drawing die to form a cup and ironing the side wall of the formed cup between an ironing punch and an ironing die to reduce the thickness of the side wall.
  • the structurally weakest portion of a draw-ironed can is the portion double-seamed to a can end, and when the can receives shocks on falling or the like, this portion is broken or leakage is caused in this portion.
  • Another object of the present invention is to provide a draw-ironed metal vessel of a tin-plated steel plate in which there is not a portion double-seamed to an end and the sole seam present in the vessel is a circumferential side seam formed by lap-bonding of open end portions of two confronting seamless cups.
  • Still another object of the present invention is to provide a draw-ironed metal vessel of a tin-plated steel plate, which has a smaller thickness of the side wall portion than in the conventional draw-ironed tin-plated steel plate cans and is excellent in the light-weight characteristic, the pressure resistance and the shock resistance and which can easily be disposed of because of a high easy crushability.
  • a further object of the present invention is to provide a draw-ironed metal vessel formed by draw-ironing of a tin plated steel plate, which has a circumferential side seam excellent in the bonding property and in which the adhesion of a coating is high.
  • the metal vessel of the present invention is characterised in that said lower member is formed by draw-ironing a tin-plated steel plate at an ironing ratio (R,) of at least 20%, said ironing ratio (R 1 ) being defined by the following formula: wherein T B is the thickness of the bottom portion of the lower member and T w is the thickness of the side wall portion of the lower member, said lower member being subjected to a surface treatment with phosphate and/or chromate and having a protective varnish on the entire surface thereof, said upper member is formed by shallow drawing of a protecting varnish-coated tin-plated steel plate, the adhesive is a heat-fusion-bondable thermoplastic resin having a melting point or softening point of 130 to 240°C, and that the lap-bonding is conducted by heating to fuse the adhesive of the seam and cooling the seam.
  • R ironing ratio
  • a draw-ironed metal vessel comprises a lower member 1 formed of a seamless molded cup of a tin-plated steel plate and an upper member 2 formed of a seamless molded cup of a metal. These molded cups are integrated in the form of a vessel by lap-bonding open end portions 3 and 4 to form a circumferential side seam 5.
  • the lower member 1 comprises a tall thin side wall portion 6 formed by deeply draw-ironing a tinplate blank and a thick bottom portion 7 which is not substantially ironed.
  • the upper member 2 comprises a short side wall 8 formed by shallow drawing of a tinplate blank and a top wall 9.
  • the height of the side wall portion 8 of the upper member 2 is equal to or slightly larger than the width of the seam 5.
  • the top wall 9 of the upper member 2 has a convex taper face, and a spout 10 for charging and discharging the content is formed at the center of the top wall 9.
  • the upper member 2 is bonded in the form of a shoulder and neck of a so-called bottle to the lower member 1.
  • the open end portion 3 of the lower member 1 is drawn by necking-in of the adjoining portion so that the diameter is smaller than that of the other barrel wall portion, and the open end portion 3 is fitted and inserted in an open end portion 4 of the upper member 2 having a larger diameter.
  • An adhesive layer 11 is formed between the outer surface of the open end portion 3 of the lower member and the inner surface of the open end portion 4 of the upper member to effect bonding and integration of the upper and lower members. From the viewpoint of the corrosion resistance, it is preferred that a part of the adhesive 11 be protruded from the seam 5 to form a coating layer 13 for a cut edge 12 of the tinplate blank located on the inner side of the seam.
  • the side wall 6 of the lower member constituting a main part of the barrel portion of the vessel is ironed so that the ironing ratio R, defined by the following formula: wherein T stands for the thickness of the bottom of the molded cup T w stands for the thickness of the side wall of the molded cup, is at least 20%, preferably 30 to 80%.
  • the tinplate vessel of the present invention is characterized in that, as pointed out hereinbefore, the side wall constituting a main part of the barrel portion of the vessel is highly ironed and the thickness is reduced, the sole seam present in the vessel is a circumferential side seam, and this seam is formed by lap bonding.
  • the buckling tendency is obviated at the sealing step.
  • the axial load applied to the vessel barrel is in the range of 50 to 100 Kg and is smaller than about 1/2 of the axial load applied at the double-seaming step. Therefore, the buckling tendency is considerably reduced as compared with the case of double seaming.
  • the circumferential side seam present in the tinplate vessel of the present invention is formed by lap bonding having a high resistance against a load applied in the axial direction. Accordingly, the structure of the vessel of the present invention is highly resistant to pressures or shocks. In case of double seaming, bonding by folding (lock seaming) or butt bonding, if the thickness of the blank is small, the blank constituting the seam is first deformed by the load applied to the seam, and because of this deformation, leakage at the seam or breakage of the seam is caused under a relatively small load.
  • the thickness of the main portion of the barrel of the tinplate vessel is reduced by high ironing, the weight of the vessel per unit volume is drastically reduced and the material metal cost can be lowered. Further, in the barrel portion of the vessel of the present invention, a fresh metal face is exposed to the outside by high ironing, and therefore, the adhesion to a protecting paint and the adhesion to an adhesive used for formation of a seam are highly improved. This is another advantage attained by the present invention.
  • tinplate blank for formation of the vessel of the present invention tinplate having tin deposited in an amount of 0.1 to 1.0 Ib/B.B. on one surface is preferably used.
  • the deposited tin layer may be one subjected to a remelting treatment (reflow plate or bright plate), or it may not be subjected to this treatment (non-reflow plate or matt plate).
  • a tinplate blank is relatively difficult to bond by an adhesive.
  • a tin oxide layer should naturally be formed in the surface portion of the deposited tin layer. This tin oxide layer is poor in the mechanical strength and is brittle. Accordingly, it is believed that in a vessel formed by bonding such tinplate by an adhesive, the tin oxide layer present in the bonding interface is readily peeled, resulting in drastic reduction of the bonding strength.
  • the side wall portion of the upper or lower member, to be formed into a circumferential seam is subjected to a drawing processing or a high ironing processing, peeling of the tin oxide layer and exposure of a fresh metal surface are effected, and therefore, the adhesion or bonding property to an adhesive or primer is highly improved.
  • a tinplate blank such as mentioned above is punched into a disc or the like and is subjected to one-stage or multi-stage drawing between a drawing punch and a drawing die, and multi-stage ironing is carried out between an ironing punch and an ironing die.
  • Drawing and iron conditions are known, and drawing and ironing can be accomplished very easily according to known procedures while controlling the ironing ratio in the above-mentioned range.
  • the thickness of the tinplate blank to be processed be 0.2 to 0.5 mm, especially 0.2 to 0.35 mm, though the preferred thickness is varied more or less according to the size of the final vessel, and it also is preferred that the thickness T w of the side wall portion formed by ironing be 0.05 to 0.20 mm, especially 0.06 to 0.17 mm, while the ironing ratio is in the above-mentioned range.
  • the ironing ratio of the open end portion of the cup to be subjected to a necking-in treatment is lower by 5 to 30% than the ironing ratio of the other side wall portion, this portion is advantageously prevented from being damaged at the necking step.
  • a method in which the ironing operation is performed in at least three stages while gradually narrowing the clearance between a punch and a die and the open end portion is prevented from being ironed at the ironing step of the final stage.
  • the operation of necking-in the draw-ironed cup is carried out so that the upper and lower members come to' liave such sizes that they are precisely fitted together.
  • the outer diameter r, of the open end portion to be located on the inner side of the circumferential lap bonding to be formed, the inner diameter r o of the other open end portion to be located on the outer side of the circumferential lap bonding and the thickness d A of the adhesive layer to be interposed between both the open end portions are selected so that the relation of r o -r l ⁇ d A is established, both the open end portions always press the adhesive layer and tight bonding and assured sealing at the seam become possible.
  • the draw-ironed molded cup is subjected to trimming and after washing if necessary, the cup is subjected to a surface chemical treatment with a phosphate and/or a chromate. Then, an anti-corrosive protecting varnish is applied to at least the inner surface of the cup.
  • the phosphate and/or chromate treatment may be seen that P and/or Cr is deposited in an amount of 1 to 2, mg/m 2 as the atom on the surface of the deposited tin layer.
  • the edge of the open end portion of the cup should naturally be treated, and even if this open end portion is located on the inner side of the seam and exposed to the packed content, it shows a high corrosion resistance.
  • the adhesion to an adhesive is improved and also the adhesion of a paint or resin coating to be applied later is improved.
  • thermosetting and thermoplastic resins for example, modified epoxy paints such as phenol-epoxy paints and amino-epoxy paints, vinyl and modified vinyl paints such as vinyl chloride/vinyl acetate copolymer paints, saponified vinyl chloride/vinyl acetate copolymer paints, vinyl chloride/vinyl acetate/maleic anhydride copolymer paints, epoxy-modified epoxyamino-modified vinyl resin paints and epoxy-modified epoxyphenol- modified vinyl resin paints, acrylic resin paints, and synthetic rubber paints such as styrene-butadiene copolymer paints.
  • modified epoxy paints such as phenol-epoxy paints and amino-epoxy paints
  • vinyl and modified vinyl paints such as vinyl chloride/vinyl acetate copolymer paints, saponified vinyl chloride/vinyl acetate copolymer paints, vinyl chloride/vinyl acetate/maleic anhydride copolymer paints,
  • paints are applied in the form of an organic solvent solution such as a lacquer or enamel or an aqueous dispersion or solution by spray coating, dip coating, electrostatic coating or electrophoretic coating.
  • organic solvent solution such as a lacquer or enamel or an aqueous dispersion or solution
  • spray coating dip coating
  • electrostatic coating electrophoretic coating
  • the coating is baked according to need.
  • the shallowly drawn cup as the upper member is formed by shallowly drawing a metal blank, to which a varnish as mentioned above has been applied in advance, by using a pressing mold or a combination of a drawing punch and a drawing die. Then, the top wall of the formed cup is punched to form an upper member having a pouring mouth.
  • Lap bonding of the upper and lower members is accomplished by using an adhesive.
  • an adhesive is applied to at least one of the open end portions of the lower and upper members to be bonded and both the open end portions are fitted together.
  • a heat-fusion-bondable thermoplastic resin having a melting or softening point of 130 to 240°C is used as adhesive.
  • nylon type adhesives such as nylon-13, nylon-12, nylon-11, nylon-6,12 and copolyamides and blends thereof

  • olefin adhesives such as an acid-modified olefin resin, and ethylene/acrylic acid ester copolymer, an ion-crosslinked olefin copolymer (ionomer) and an ethylene/vinyl acetate copolymer.
  • the adhesive is applied in the form of a film, powder, dispersion or solution to each of the open end portions to be bonded to form a heat-bondable adhesive layer uniformly along the entire circumference of the open end portion.
  • the open end portion to be located on the outer side of the seam is heated to increase the diameter or the open end portion to be located on the inner side of the seam is cooled to diminish the diameter, whereby the fitting of both the members is facilitated. If this means is adopted, the fitting can easily be accomplished even when the relation represented by the above-mentioned inequality is established among the outer diameter of the inner end edge, the inner diameter of the outer end edge and the thickness of the adhesive layer.
  • the seam is heated to fuse the adhesive layer, and the seam is cooled to effect bonding and sealing on the seam. Since the adhesive layer is fused at this step in the state where the adhesive layer is pressed in both the end edge portions bonding and sealing on the seam can be accomplished completely. Heating of the seam is advantageously performed by high frequency induction heating.
