Definitions

  • Ziehmer ABSTRACT Can body blanks to be used in production of cemented lap side seam containers are pre-coated with a pigmented epoxy-type coating which, when the body blank is lap side seamed, functions to provide a bonding interface for the lap side seam adhesive while simultaneously functioning as an adherent base upon which to apply printing or other decoration for the exterior surface of the can body thereby permitting elimination of heretofore necessary binding lines and size coat.
  • CEMENTED LAP SEAM CONTAINER BACKGROUND OF THE INVENTION Cemented, as opposed to soldered, side seam bodies are known in the art. Cans produced from such bodies have found a substantial degree of commercial success for the packaging of products which generate no substantial internal pressure, such as frozen citrus concentrate, household cleaners and polishers, and the like.
  • One of the major selling features of such can bodies is that it is possible to provide printed decorations, as opposed to paper labels, completely around the external surface of a can body.
  • such prior art cemented side seam bodies do not have a high degree of bursting strength, particularly when the can is subjected to conditions necessary to process certain products such as the sterilization cooking for fruits and vegetables, or pasturization of beer.
  • tubular sheet metal can bodies having opposed longitudinal edges overlapped to form a lap side seam are provided wherein the opposed surfaces of the sheet metal include within the lap side seam an organic coating containing epoxide resin and high-strength organic adhesive disposed within the lap side seam and adhered to the organic coating.
  • the coating extends over the entire flat surfaces of the sheet metal and as a result thereof over the entire inside and outside surface of the can body.
  • the coating employed in said copending application also provides an adherent base upon which to apply printing or other decoration for the outside surface of the can body and the decoration is most conveniently applied in the flat, i.e., to that surface of the blank which will later form the outside surface of the can body.
  • the decorative coating has not been permitted to extend into the margin to which the adhesive is to be applied so as to assure that the adhesive would be bonded directly to the coating.
  • the top coated or decorated blank contains an unpigmented or undecorated area usually seen as a ragged edge which detracts from the overall aesthetic effect. This area is usually hidden by binding lines. This is an added and expensive operation and detracts from all around'lithography and decoration; there is therefore within the can making industry a considerable need for a container, produced by a cemented lap side seam process, which retains the advantages of containers produced by such a process, from a can body blank to which a protective and decorative coating has been applied to the entire exterior surface, which eliminates the need to apply a first size coat followed by a decorative coat followed by application of binding lines.
  • Another object of the present invention is to provide a lap side seam can body having applied thereto such an exterior pigmented coating and having exceptionally high bursting or hoop strength.
  • Another object is to provide a lap side seam can body having applied thereto such an exterior pigmented coating and which maintains its high bursting or hoop strength even after it is subjected to prolonged conditions of moist heat.
  • Yet another object is to provide a decorated lap side seam can body which can be made rapidly on high speed automatic equipment.
  • a further object is to provide a method for production of a lap side seam can body which eliminates the necessity of applying a first size or prime coat, a decorative top coat and binding lines as in the prior art.
  • a tubular sheet metal, lap side seam can body having as a decorative coating on its entire exterior surface, a baked organic coating containing a pigmented cured epoxide.
  • this coating is the heat-cured reaction product formed by applying and baking a coating composition comprising an epoxy resin and a pigment, for example, an epoxy ester and titanium dioxide, the pigment to non-volatile vehicle ratio preferably being about 4065 parts pigment per 60-35 parts nonvolatile vehicle, the opposed coated surfaces being bonded together with a linear superpolyamide adhesive.
  • This can body is formed from a flat blank having at least one entire surface coated in the manner described and having the adhesive applied, before bonding of the lap side seam, to the coating on at least one of the longitudinal margins thereof.
  • the method and apparatus for making the can body blank is described in U.S. Pat. No. 3,481,809 in the names of Edward William Kaiser, Arnold Robert Rein and Richard Otto Rahler.
  • the steps of forming the blank into tubular shape, applying the superpolyamide to the longitudinal margin areas, heating the adhesive, and pressing the opposed lap seam surfaces together between chilled supporting surfaces are effected automatically, less than about one second being required for heating the adhesive and pressing the lap seamed surfaces to form the bonded seam.
  • FIG. 1 is a perspective view of a can body blank of the instant invention.
  • FIG. 2 is a perspective view of a can body of the instant invention
  • FIG. 3 is a fragmentary enlarged sectional view taken along line 33 of FIG. 2;
  • FIG. 4 is a fragmentary enlarged sectional view of a can body of the prior art taken substantially along line 33 of FIG. 2.
  • FIG. 1 shows a substantially rectangular can body blank generally designated having for the metal component thereof thin guage sheet metal 11 in the order of magnitude of ten thousandths of an inch.
  • This sheet metal which may be thicker or thinner than the numerical number given, may be aluminum or low carbon steel, with or without an external plating of aluminum, chromium, cobalt, nickel or tin.
  • Completely covering the exposed, extensive exterior flat surface 14 is a particular pigmented and decorative organic coating composition 13 which will be defined more thoroughly hereinafter. Covering the extensive interior flat surface 12 is an organic coating 19 which will be defined more thoroughly hereinafter.
  • the adhesive 18 extends the full length of the margin 16 and inwardly from the edge of this margin, i.e., has a width of from three thirtyseconds inch to nine thirty-seconds inch and preferably 0.200 inch, and upwardly from the coated surfaces of the margin, i.e., has a thickness of from 0.003 inch to 0.006 inch and preferably about 0.004 inch.
  • the blank 10 is formed into an open ended tubular can body generally designated 20 (FIG. 2), on a high speed automatic, can body maker, for example of the type utilizing the body-blank applicator of the aforementioned U.S. Pat. No. 3,481,809, by lapping the blank 10 around a mandrel, heating the adhesive 18 to a semi-fluid, tacky condition and pressing onto the coated upper surface or the opposite blank margin 17.
  • the bonded side seam is chilled to set the adhesive and to secure the lapped margins together to form the can body 20 having a lapped side seam generally designated 22, including an inner lap 24 (from the margin 16) and an outer lap 26 (from the margin 17). Bonding of the lapped margins is accomplished in less than one second and preferably in about 10 milliseconds.
  • a container bodymaker which performs this function is described in U.S. Pat. No. 3,508,507 issued to A. T. L. Austing.
  • the adhesive 18 does not bond directly to the sheet metal 11 of the can body but rather to the opposed surfaces of the exterior organic pigmented epoxy coating 13 and interior coating 19 included within the side seam 22.
  • the high strength bond of the lap side seam 22 is a result of the tenacious adherence of the coatings 13 and 19 to the sheet metal 11 and to the organic adhesive 18 interposed between the coated faces of the margins 16 and 17.
  • the coating 13 extends over the entire flat exterior surface 14 of the sheet metal 11 and as a result therof over the entire outside or exterior surface of can body 20.
  • the coating 13 provides an adherent base upon which to apply printing or other decoration to the surface of the can body as well as a protective coating for the metal over its exposed surface.
  • Decoration (not shown) is more conveniently applied in the flat, i.e., to that surface of the blank 10 or of a larger sheet from which the blank is cut which will later form the outside surface of the can body.
  • the decorative'coating extends into the bonding area to which the adhesive 18 is subsequently adhered.
  • FIG. 4 wherein a protective coating 25 was first applied over which a decorative top coat 23 was applied.
  • the decorative top coat in FIG. 4 does not extend into the margin 26 to which the adhesive 28 is adhered, since adhesion is effected via bonding of the adhesive to the unpigmented size coating 25.
  • the coating 13 of this invention comprises a pigmented epoxide resin having, before curing, an epoxide equivalent of from 425 to 6,000 and a number average molecular weight of from 1,000 to 4,000 and components coreactive therewith upon application of heat to form an epoxy resin which is preferably an epoxy-ester, epoxy-amino or epoxyphenolic resin, and such classes of resins modified with various additives such as melamine, urea formaldehyde resins and mixtures thereof.
  • Epoxy-ester resins generally derived by reaction of an epoxy-ether having an average molecular weight of about 1,000 to 2,000, and having an epoxide equivalent weight of about 875 to l ,025 with a fatty acid, as for example, saturated and unsaturated fatty acids derived from linseed oil, soya. dehydrated castor oil, tall oil, etc., or simple fatty acids such as oleic, lauric, stearic, palmitic, myristic, linoleic, sorbic, etc. and mixtures thereof may be employed and are especially preferred herein.
  • Epoxy-ester resins are generally obtained by esterifying an epoxy-ether with said acids in relative proportions of about 1 equivalent epoxy to about 0.3 to 0.9 equivalent of fatty acid.
  • epoxy-amino resins derived by reaction of epoxy-ethers having an average molecular weight, before curing, of about 900 to about 4,000 with various amino-containing resins such as melamine, triazine, ureaformaldehyde, etc.
  • Such epoxy amino resins are generally obtained via reaction of epoxy ethers, for example, diglycidyl ether of bisphenol A with such amino-containing resins in relative proportions varying from about 95/5 to 50/50.
  • epoxy resins include epoxy-phenolic resins which include reaction products of various polyhydricphenols for example, allyl ether of polymethylol phenol, polymethylol tertiary butyl phenol, polymethylol p-phenylphenol, etc., with epichlorohydrin and similar epoxidic materials by methods known in the art.
  • Suitable epoxides of this class will have, before curing, an epoxide equivalent of about 425 to 6,000 and an average molecular weight of about 1,000 to 4,000 and include polyglycidyl ethers of bisphenol A, epoxidized novolacs, etc.
  • the epoxy-ester, epoxy-amino and epoxyphenolic resins suitable for use in the invention are well known in the art and may be prepared by incorporation of the reacting components in the formulation including catalysts and modifying agents as desired. Particularly preferred are such resins modified through further reaction with melamine, ureaformaldehyde resins and combinations thereof.
  • the epoxy resins, as employed herein, are pigmented with proportions of pigment to non-volatile vehicle being generally within the range of about 40 to 65, preferably 50 to 60, parts by weight of pigment to 60 to 35, preferably 50-40, parts of nonvolatile vehicle.
  • suitable pigments are titanium dioxide, colloidal silica, zinc oxide, and aluminum pastes or powders. Both rutile and anatase forms of titanium dioxide are preferred for use herein with rutile titanium dioxide being especially preferred.
  • Extender pigments may be employed where desired.
  • such ingredients are not employed particularly in formulating white coatings which are applied as relatively thin films and any substantial use of extenders would tend to detract from the desired coverage and aesthetic quality of the coating.
  • conventional extender pigments known in the art for example, calcium carbonate; may prove suitable.
  • Various other additives such as flow control agents, suspending aids, and compatible lubricants may be employed as desired.
  • the coating 13 is preferably applied as a dispersion of the above described ingredients, before their interreaction, in a fugitive liquid. It is necessary that the liquid be volatile at baking temperatures which may be as low as 300F. or as high as 650F.
  • Suitable solvents comprise aryl or aralkyl hydrocarbons blended with alcohols, ketones, ethers or esters and mixtures thereof. Alcohol, ketones, ethers or esters or mixtures thereof may be employed without aryl or aralkyl hydrocarbons if desired. Solvent systems comprising a mixture of aryl or aralkyl hydrocarbons and alcohols yield solutions having optimum viscosity for application and for this reason are preferred.
  • a specific example of a fluid composition for application to the metal sheet 11 to provide the finished coating is as follows:
  • epoxy based coatings may be employed to form interior coatings 19 for the interior surfaces 12 of the container body.
  • Such coatings may be unpigmented or pigmented epoxy resins as described above, or mayinclude any of well known coatings employed for this purpose.
  • such other coating which may be employed is an epoxyurea-formaldehyde coating wherein the epoxy component is a l, 2-epoxide resin substantially similar to the epoxy-ethers hereinbefore described.
  • the inside coat for beverage containers be of some color. This preference has more significance in lap seam cemented cans because a coating must also be applied to the exterior surface in order to do the cementing job.
  • Such a colored inside coating is desirable since it is often desired to have a difference in color between the inside and the outside of a container body, so that the printing press man can immediately determine if he is printing on the correct side of the sheet. For this reason it is preferred that the can body blank be coated on the surface that is to form the interior of a container body with an epoxy resin having a pigment different from that applied to the exterior surfaces, for example, a gold tartrazine lake pigment.
  • the decorative, pigmented epoxy exterior coating may, if desired, be coated with a further clear varnish for protection of the decorative label once it has been applied.
  • varnishes may be conventional lacquers such as alkyds, acrylics, etc. It will be understood, however, that such additional coating is not mandatory nor is it limited to the specific examples above enumerated and may include any of conventional coatings known in the art.
