AMERICAN CAN COMPANY,
To all whom it'may concern:
Be it known that l, FRANKLIN RUDOLPH, a citizen of the United States, residing in Chicago,-in the county of Cook and State of 5, Illinois, have invented a new and useful Improvement in Sheet-Metal Containers for the Preservation of Food, of which the following is a specification.
his invention relates to an improvement it in sheet metal containers for the preservatipn of food and the invention consists in lacquering the interior of the can with a \multiplicity of coatings to adapt it to resist the destructive action of contents of difterent kinds. In the accompanying drawing which forms a part of this specification, Figure l is a diagrammatic Viewv of an; ordinary sheet metal can or container such as is used in the preservation of various food products as I fish, beets, vegetables.- Fig. 2 is an enlarged, fragmentary section of any one of the walls of the container or of the two ends thereof to illustrate the use of the multiplicity of lacquerings or-coatings.
One of the most serious ditliculties encountered in the manufacture of sheet metal food containing cans in which to pack and preserve food by the process of sterilization by heat, has been the fact that in some cases the food contents has an acid reaction, for example, and in other cases, an alkaline reaction and in still other'lcasesaa difierent chemical corrosive efi'ect upon theiinte'rior of the can. It has been found necessary in many cases to protect the interior of the sheet metal vessel by a coating to guard against the formation of poisonous salts of tin due to the chemicalaction of the condition to this,
to tents upon the tin coating of the sheet metal.
vessel. Thus the interior 0 been lacquered orvarnished by lacquersof -various kinds. But itha'sbeen found, that these lacquers donotalways protect the tin at coating from the actio'nbf the contents and specialfprovision is y he lacquer or coating fer-ent kinds of contents and sometimes, as
in the case of shrimps, crabs, lobsters, it has required to be inade-v use of some particular kind of iniconnection with dif+ specification of Letters Patent. Application filed March 9, 19M; Serial, Ito. 823,333.
consisting of any 0 shellac in an t tin cans has ond coating Patented not. as, rare.
been found necessary to protect thelacquer by inclosing the contents in parchment or cloth cases within the can.
The present invention consists in coating the interior of the tin sheet metal vessel or container With a multiplicity of coatings, each of a different character and adapted to resist a different chemical action. Thus, for example, to illustrate my invention and en able others to practice the same, I coat the interior of the tin can first with a lacquer f the suitable varnish gums held in solution in benzol-and bake the same on in the ordinary way. Thereafter, when this coating is dry and hard I apply a second coating consisting, for example, of alcoholic solution which I spray upon the interior of the lacquered or coated can. The result is, a can which will A resist all of the kinds of contents that may 70 be resisted by the shellac coating and, all of the kinds of contents that may be resisted by the baked on coating. Moreover, in adthe vdouble coating also tends to cover up any defects that may exist in either one of the coatings.
The utility of the container is thus greatly enhanced while its expense of manufacture is not materially increased. ,,-In the illustrative section at Fig. 2, A is the sheetof iron provided with a coating B of tin on each side thereof, U represents the baked on lacquer with a benzol solvent and D represents. the sprayed" on lacquer with the alcoholic solvent, the whole representing 85 a fragmentarysection of the form ofthe invention'used herein to illustrate the-same.
I hereby disclaim-as not ofmyinvention the aluminum lined can shown and described in the Norton Patent #863,086 dated August 13, 1907. L
