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 packing and preserving fish, meat, soups, fruits,
and other analogous things, in metal packing boxes or cans, that is to say, thin
metal boxes of kinds such as are at present commonly used and employed for
holding or preserving what is generally called canned goods, the object being to
provide an improved package, by which, while the purity of the goods is effected,
the box or can can be cheaply and conveniently made, and the method of packing
an easy and convenient one.
According to this Ginvention, the package or can, that is, the body and bottom,
is made of suitably prepared black steel or iron sheet metal, seamed at the side
and bottom. The metal of which it is made is pickled and annealed, and then
cold-rolled until its surface becomes smooth and bright; in which condition, the
pieces of metal are seamed up. This article constitutes the rough body of the
case or can. When the body is complete, the inside surface is completely covered
or coated with enamel material, the enamel being of the consistency of paint,
which, after application, is burnt in or fired in a muffle-furnace, or the like; after
which the outside of the can may be cleaned up and made bright.
On the top of the goods packed in the body of the can, I employ a disc of metal,
also covered with enamel of a similar nature to that employed in the body, and
applied in any convenient way, the disc being substantially of the full diameter
of the case. The goods within the can are thus entirely enclosed at the top,
bottom, and sides, by, and in contact only with, enamelled surfaces. Then over
this disc, is fitted a metal lid, which, in one form, is a shallow dished cover, of tin
plate, just falling over the edge of the case; while the upper part of the case is
provided with a projecting annular bead, up to which the short flange of the cover
or lid will come; and at this point, the lid is soldered to the body. This con-
struction enables the soldering action to be effected conveniently and satisfactorily.
The inside of the outer lid may, in some cases, be enamelled, if desired.
The food stuffs packed in boxes or canisters of the kind referred to remain
sweet and preserve their natural flavour, owing to the enamel being entirely inert,
as regards the materials packed, and consequently tasteless.

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 packing and preserving fish, meat, soups, fruits,
and other analogous things, in metal packing boxes or cans, that is to say, thin
metal boxes of kinds such as are at present commonly used and employed for
holding or preserving what is generally called canned goods, the object being to
provide an improved package, by which, while the purity of the goods is preserved,
the box or can can be cheaply and conveniently made, and the method of packing
an easy and convenient one.
The invention will be described with the aid of the accompanying drawing,
which shews a can or package, filled and sealed, in cross section.
According to this invention, the package or can, that is the bottom and body a,
is made of prepared black steel or iron sheet metal; the preparation consisting
of pickling and annealing, and then cold rolling, until its surface becomes smooth
and bright; in which condition, the pieces of metal cut from it are seamed up.
The upper edge of the can is provided with an external bead or corrugation b,
just below the lip of the can-which is a very short cylindrical part of the body-
for the purposes hereafter described. This article constitute the rough body of
the case or can. When the body is thus far made, the inside surface is com-
pletely covered or coated with a suitable enamel material constituting a coating
or lining which is designated c; the enamel, when applied, being of the consistency
of paint, which, after application, is burnt in, or fired in a muffle furnace, or the
like; after which the outside of the can may be cleaned up and made bright. In
this condition the can is ready to receive its contents; the whole interior surface
of which, which is presented to, and comes in contact with the goods, being of
enamel, capable of resisting the action of all acids, and is wholly inert as regards
the contents.
In my improved can, on the top of the goods, when the can is charged, a flat
or plain disc d, covered or enclosed with enamel on both sides, and substantially
of the full internal diameter of the case, is employed. And then again, over this
disc, is fitted or provided the metal lid e, which is in the form of a shallow dished
cover of tin-plate, the edge of the flange of which will come down close to the
upper surface of the bead b; and the hermetical joint of this cover with the body,
is made by applying or filling solder into the groove or space between the lower
edge of the lid flange e¹, and the upper part of the bead b, the jointing solder
being indicated by the letter f.
The disc d is comprised of a thin metal plate, preferably of black iron or steel
sheet prepared as described above; and it is entirely enclosed or enveloped with
enamel designated d. The enamel, of course, is burnt in or fired in the same
way as that in the interior of the body.
When a can is filled, it is known that a vent hole has to be provided in the
cover or lid, and that, subsequently, it is closed by solder. In this can or package,
when the can is filled, the disc b will be close up against the underside of the lid;
and thus when the solder is applied to close the vent hole, drops of solder cannot
get into the package at all, as the enamel disc directly under the hole stops its

page_text: entrance; and, moreover, the solder cannot even project into the can. The lid,
furthermore, being of tin-plate enables the hole to be readily soldered up by
solder, which could not readily be done with any other metal; and it also enables
the edge to be readily soldered to the outside of the body of the can.
It will be seen that the goods thus packed within the can are thus entirely
closed at the top, bottom, and sides, by, and in contact only with enamel surfaces;
hence, food stuffs packed in them remain sweet, and wholesome, and no deleterious
or dangerous substances or compounds are formed within the can after packing.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
―
1. A metal can or package for perishable food-stuffs consisting of a body of sheet
steel or iron having an internal lining or surface of enamel integral with it, made
by first cold rolling the black sheet steel or iron until it is bright, and then form-
ing into a can with seamed joints, and then covering the interior surface of the
can so formed with enamel, and "firing it"; substantially as set forth.
2. A metal can or package for perishable food stuffs, comprising a body, a, of
plain steel or iron plate, having an internal lining or surface of enamel, c, fired
onto and integral with the metal; an externally enamel coated disc d placed above
the goods in the can body, and substantially of the full internal diameter of the
can, and filling the mouth thereof; and a metal cover e fitting over the mouth
of the body a, and soldered thereto; for the purposes described.
3. The metal can or package for food stuffs, having or consisting of the parts
particularly as set forth with reference to and shewn in the drawings, for the
purposes specified.
