Improvements in or connected with Metallic Packing Boxes or
Canisters for Packing Fish, Meats, Fruits, and other Edibles or
"Food.
I, WILLIAM JAMES HARRIES, of 28, Chapel Street, Liverpool, in the County of
Lancaster, Metal Merchant, do hereby declare the nature of this invention to be
as follows:-
This invention has reference to metallic packing boxes or canisters employed
for packing fish, meat, soups, fruits, and other analogous food; that is to say, to
thin metal boxes such as are at present commonly used and employed for holding
and preserving what goes generally under the title of "tinned goods." And the
object of this invention is to provide an improved package or canister by which
the absolute purity and preservation of the goods packed, is effected.
According to this invention, the package or canister is made of suitably prepared
black steel or iron, seamed at the side and bottom, or stamped in one piece without
scam, or made generally in the same manner as tin plate packages or boxes, and
when so made, the inside surfaces are completely covered or coated with enamel
material, such as is used for enamelling iron or steel sheets; and the enamel is
burned or fused onto the steel or iron surface, and then cooled, when it will have
become hard and fused or amalgamated with the steel surface. The lid or cover
is similarly enamelled on the inside, and when the box or case is filled with the
perishable goods, the lid is soldered on, making a hermetically closed cover, and
tight case; the soldering or fixing of the lid to the body being effected either with
solder round the edge of the lid, which fits over the mouth of the canister, or by
soldering a thin strip of tin-plate round the edge, so sealing the cover or lid flange
with the body. In the latter case, a small tag may be provided, so that the lid
can be easily torn off when required; in opening the package.
Prior to the filling, the outside of the body or canister is, in some case, burnished,
and when filled and closed, is painted or varnished with a thin coating of varnish
or paint.
In cases where the canisters are pricked after 'immersion in boiling water, they
can be soldered up in the same way as tin-plate canisters or boxes.
Food stuffs of the kind referred to, packed in boxes or canisters, as described,
preserve their natural flavour in a high degree; as the enamel interior surface,
in contact with which they come, is pure, tasteless or sweet, and inert as regards
the materials packed, as crockery or porcelain.

I, WILLIAM JAMES HARRIES, of 28, Chapel Street, Liverpool, in the County of
Lancaster, Metal Merchant, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
This invention has reference to metallic packing boxes or canisters employed
for packing fish, meat, soups, fruits, and other analogous food; that is to say, to
thin metal boxes such as are at present commonly used and employed for holding
and preserving what goes generally under the title of "tinned goods." And the
object of this invention is to provide an improved package or canister by which
the absolute purity and preservation of the goods packed, is effected.
A can according to this invention, is illustrated in the accompanying drawing,
which is a sectional elevation. In the drawing, a represents the body metal,
namely, thin sheet metal, and the internal lining covering entirely the sides and
bottom. represents the metal lid, and the enamel lining covering the internal
surface of the flanges and roof thereof. The lid may be made air tight on the body
when filled by any suitable known means; in the drawing a thin strip & being
shewn soldered to the edge of the flunge of the lid and the body.
The body and cover or lid of the case, as stated, are made of thin sheet steel
or iron; and the whole interior surface is covered entirely with enamel fired onto
it, and which is practically integral with it, similar to enamel metallic goods, the
enamel being, preferably, of any known kind possessing a certain amount of
elasticity, so that it is not liable to crack off readily.
The enamel can be applied to the interior of the case by means of a brush or
spatula, that is, by painting it on the interior surface, the material being of the
consistency of paint. A can thus coated internally, is then placed in a suitable
muffle furnace, and subjected to sufficient heat to fire it, and when sufficiently
fired, is removed and cooled down. The can can thus be polished externally, and
rendered bright by an emery wheel, or by any suitable means.
The lid is treated, built or seamed up, enamelled internally, "fired," and
polished in exactly the same way as the body. The can is then ready to receive a
the contents; and when filled, and the lid applied and soldered on, the case is
hermetically closed in any known suitable way. The outside of the can may thon
be varnished and finished or treated in any required way.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed; I declare that what I
claim is:-
The herein described packing box or canister for packing fish, meats, fruits,
and other edibles or food, consisting of a thin sheet metal body, and lid adapted
to fit over the upper end thereof, and an internal lining or coating of enamel
fired" onto the metal, and constituting an integral part thereof, said body and 4
lid being made, and the enamel applied, substantially in the manner set forth.
