PROCESS OF HERMETICALLY CLOS/ING SARDINE-CANS. .f
Be it known that I, GEORGE W. WEBER, a citizen of the United States, residing in New York, in the county lof New York and State of New York, have invented a new and useful Improvement in Processes of Hermetically Closing Sardine-Cans, of which the following is a specification.
This invention relates to a process of hermetically closing cans, and especially cans containing oily products, such as sardines.
The invention consists in coating. a flanged can body and .its flanged cover 1nterior-ly with a coating of protective lacquer, baking the same thereon, filling the can, allowing the lacquered surfaces to become oiled and then uniting the lacquered surface ofthe cover to the lacquered surface of the body by heatand pressure and holding the united surfaces together until cold. v
Y In the accompanying drawings vwhich* form a part of this specification, Figure 1" is a sectional view of a can body and its cover. Fig. 2 is a `sectional view ofthe 1nteriorly llacquered filled ,can and its cover inthe act `of being united by heat and pressure. VFig is a sectional view of the completed product, thelacquered, filled, hermetically sealed can, and Fig. 4, is a sectional view o fa Vdouble seam of the ordinary type, -showing diagrammatically away of applying heat to the seam, o1 heat and Sanitary reasons have suggested v the widespread employment of a protective lacquer for the interior of cans containing food products, and/such'lacquering has been found desirable in the canning of sardines and such oily food products, containingl Asometimes olive .oil ,and sometimes 'cotton seed Oil. Such cans'have usually-been hler-l metically sealed `by means `of soldered. seams, though sometimes such sealing effected by means of folded seams with an interposed gasket ofsome gummy composition.
I have discovered by-l experiment, and
herein this invention consist's, thaty if bbth surfaces ofthe joint be coated with the ordinary protective baked-on 1acquer,such as used for coating the interior of food product vessels and the caps or covers/there-` for, andv which 'is baked. on, andsuch vsur-l faces oiled, as, for example, with the'loil contained in filled sardine cans, and pressed Specification of Letters Eatent. l
hold the two together.

together and heated, the 'joint will unite into a perfect, hermetic seal, sufiiciently strong and sound for the purpose of preserving the ,contents of the can.`
In the accompanying drawing, A repre- 6 0 sents a common sardine can made with the flange a.
in Fig. 3. o ,1 C is the ordinary protective coating of' lacquer applied tothe interior of the can and the cover and baked thereon. It will be sufficient if this protective coating is applied to the interior surfaces of the flanges .of the can and cover, but I prefer to coat the entire interior of the can and ofthe cover.
This protectivecoating is baked on the can and cover in the usual Way well known to those skilled in the art of coating the interior of. food product cans .with a protective lacquer.
After the can and its cover have been thus.
coated-and the coating baked on, the can isfilled with sardines and oil or any desiied food product, the lacquered surfaces of the flanges' of the can body and can cover lbeing oiled and the can body and can cover '85 brought together and preferably secured toi gether by folding one of the flanges over the other, as, for example, the flange of the cover over the flange of the can body to flanges are brought together, heat-and pressure are` simultaneously applied to the two flanges, as, for example, by placing the filled covered can in a support D andfbringving. a gas heated pressure plate E down 95 upon the joints'so supported until the heat and oil have .acted together to soften the baked lacquer upon the two joined-surfaces pressed together, after-which `the joint is" allowed to cool while still held firmlyl tof 'getheig whichresults in a' sound, hermetically `joining lof the cover and body, sulficie'nt to preserve the contents.

After the AJtwo 90 that. it is de: sirable to softenthe bakedlac uered surface .105 'by applicationof oil or similar substance sox ` sea ing of lacquer, 'softening the baked lacquer double seam, as sh vided with a ordinary manner a heated means, such, for instance as a roller, is applied to the seam and the seam\heated to a higher tempera ture than was used in baking the' lacquered coating on theqtin, previous to making the seam, the saniehernfietic joint is obtained, of like durability and efficiency as lwas obtained by applying a softening. oil orsuch substance to the surfaces Cbefore closing thai` Seam: x j- It is also to be noted that. this method is alsoiadapted to the sealing of filled cans of any description and particularly to that type known to thetrade as sanitary or open top cans, which arekclosed by means 'ofa seam generally known asia double seam.
This type of can is marketed in various wa' sv .for certain purposescans'being provi' ed `with a 1rirotective lacquer coating, which covers t e insides only, while for other purposes, cans are provided with a protective lacquer coating coveringrthe enjtire 4can vboth inside and outside. hns, in
the latter type, does this method of seal-H ing excel, since every surface of the. folded own` lin Fg. 4,.ois pro= rotective coating which when eatv under proier. con tions, reduces lier-l itiion. @XH
