PROVISIONAL SPECIFICATION.
Improvements in Cans, Boxes, Jars, and other similar Receptacles
and Covers therefor.
1, JOSEPH KENYON, of Whalley Street Tin Works, Holland Street, Butler Street,
Manchester, in the County of Lancaster, Iron and Tin Plate Worker do hereby declare
the nature of this invention to be as follows:-
This invention refers chiefly to that class of metallic receptacle for packing or
storing small quantities of goods, known as cans, tins, or canisters, from which the
covers are removed by a lever applied thereto fulcrumed on a shoulder or ledge on
the top of the canister.
The object I have in view is to provide a tin or canister the cover of which will fit
more air tight than those at present in use, and I attain this end by making the top
of the canister and the cover therefor of such form that when brought together the
cover will fit over and into the top, two surfaces on the one engaging with two
surfaces on the other in such manner that each will have a grip to retain the cover in
position and prevent the passage of air.
In carrying out the invention I form the can or box cylindrical, rectangular, or
of any other required shape, preferably cylindrical. To the sides or wall of the can I
attach a metallic top or rim projecting inward for a short distance. This top receives
the cover, and is made with an annular recess or corrugation on the top side, into
which a corresponding projection on the cover fits, and with a shoulder or edge pro-
jecting upward above the top edges of the recess to form a fulcrum for the lever. The
recess may be, either of U, V, LI or other similar shape presenting two sides against
which, the corresponding projection on the cover, press. The shoulder forming the
fulcrum is placed at a little distance to one side of the recess with a space to allow
for the edge of the cover. The cover is preferably flat on top with a projecting
flange stamped to correspond in shape to the corrugated recess in the top of the
can, into which it fits, bearing tightly against both sides of the recess.
The cover
is further provided with a projecting rim, preferably wired or bent over, against
which, the lever will press to raise or remove the cover.
For receptacles such as jars, or bottles made of stoneware or glass, the invention
may be applied by attaching thereto a metallic top or rim, formed as above
described, to receive the cover.

COMPLETE SPECIFICATION.
Improvements in Cans, Boxes, Jars, and other similar Receptacles
and Covers therefor.
I, JOSEPH KENYON, of Whalley Street Tin Works, Holland Street, Butler Street,
Manchester, in the County of Lancaster, Iron and Tin plate worker, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention refers chiefly to that class of receptacle for alimentary and other
goods, known as tins, cans, or canisters, in which the lids or covers are fitted to a
rim inside the top of the tin and are removed by a lever applied thereto fulcrumed
on the top edge.

page_text: The object of my invention is to improve the shape or construction of the rim
which carries the lid so as to render the cover more air tight.
Referring to the annexed drawings.
Fig.1; is a sectional elevation of tin showing the rim constructed according to my
invention.
Fig. 2, sectional elevation of lid constructed to fit same.
Fig. 3, sectional elevation of tin with rim of slightly-modified form. \.
Fig. 4, sectional elevation of lid to fit same.
Fig. 5, sectional elevation of rim removed from the cannister.
In shaping the tin or cannister A, I form the top. edge a, preferably slightly
flaring or curved outwards, to receive the rim B, which is soldered or otherwise
securely attached thereto. The rim B, 1 form with an upward projecting flange b,
which extends above the other parts of the rim to form a fulcruin for the lever, by
which the lid is removed with a flat annular surface or ring e, projecting inward
for a short distance, over or upon which the bead or flange round the lid rests:
and with an annular recess or corrugation with two sides d and e, against which
the lid which is formed of corresponding shape bears. The flange 6, is preferably
of double thickness as shown, fitting over the top edge a, of the tin, and there firmly
secured by solder or otherwise. The sides d and e, may be placed at any suitable
inclination or position relative to each other to present two bearing surfaces for the
lid to press against and the side e may be of the same height as d as shown or of less
height. The cover or lid C, I form of shape to correspond, projecting down on its
underside to fit into the annular recess in the rim B. The one side f, of the pro-
jection, fitting against the side d, of the recess, and the other side g, against the side e.
On the outer edge of the lid C, is formed a flange or bead 7, preferably wired or bent
over against which the lever will be applied to raise or remove the cover.
The
In Figs., 3, 4 and 5, a slightly modified form of my improvements are shown. The
rim B, is constructed in practically the same way as that already described, with a
flange, a flat annular surface c, and annular recess with two sides d and e.
side e, however is less in length than the side d, but forms a surface upon which the
lid presses. The lid is made of corresponding shape, projecting downward to fit into
the recess in the rim B, with the two sides or surfaces f and g, of the projection
pressing against the two sides d and e. The cover C, as before, is provided with a
projecting flange or bead 1, round its edge.
For receptacles such as jars or bottles, made of stoneware or glass, the invention
may be applied by attaching thereto a metallic top or rim, formed as above described,
to receive the cover.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A metallic can, cannister, or other receptacle having a rim such as B, formed
with an upward projecting flange b, a flat annular surface c, and a recess with two
sides or surfaces d and e, against which corresponding sides in the lid press,
substantially as described and shown in Fig. 1 and Figs. 3 and 5.
2. In a metallic can, cannister or other receptacle the combination with a rim such
as B, having an upward projecting flange b, flat annular surface c and recess with
sides d and e,
of a lid or cover of corresponding shape, having a projection with two
sides f and g which rest upon the sides d and e, substantially as described and
shown.
