IMPROVEMENTS IN HERMETICALLY SEALED TIN CANS, CANISTERS AND THE LIKE FOR CONTAINING ALIMENTARY AND OTHER SUBSTANCES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We EDWARD HEWITT COOKE, of 67 Patrick Street, in the City of Cork,
Hardware Merchant, and HENRY TOWGOOD SEYMOUR, of 45, Old George Street, in
the City of Cork, Tin Plate Worker do hereby declare the nature of the said
Invention for IMPROVEMENTS IN HERMETICALLY SEALED TIN CANS, CANISTERS
AND THE LIKE FOR CONTAINING ALIMENTARY AND OTHER SUBSTANCES " to be as
follows:-
"
This Invention relates to improvements in the construction and hermetic scaling
or closing of tin cans, canisters and the like for containing alimentary and other
substances whereby the lid is so sealed or fastened to the can that it can be opened
by pulling a wire or its equivalent in a more easy manner than hitherto without
requiring the use of a separate opener.
In carrying out our Invention the sealing or closing may be effected either on
the top or on the upper edge of the side of the can or other vessel-the lid and the
can being formed with a rim or its equivalent in such a manner that a channel or
trough is left between the lid and the can at the joint. In this channel or trough
and all round the same we place a piece of cord, twine or other suitable packing
fitting between the rim of the can and the rim of the cover or lid. On this said
cord, twine or other packing we then place a piece of wire which passes all round
the channel or trough, the end or ends projecting so as to give sufficient hold for
the fingers to pull upon when the can is to be opened. Solder is now run in and
passes on each side of the wire and attaches itself to the rin on the cover or lid
and to the rim on the can or canister. The cord or its equivalent acts as a kind of
packing under the wire and prevents the solder from passing under the wire and
attaching the cover directly to the body of the can or canister. In practice we have
found one soldering sufficient.
To open a can or canister closed or sealed as hereinbefore described it is increly
necessary to pull the projecting end or ends of the wire and it can be readily
stripped as the slight soldering gives way casily and the cover or lid can then be
lifted off.

page_text: We, EDWARD HEWITT COOKE of 67 Patrick Street, in the City of Cork,
Hardware Merchant and HENRY TOWGOOD SEYMOUR, of 45" Old George Street, iu
the City of Cork, Tin Plate Worker do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN HERMETICALLY SEALED TIN CANS, CANISTERS
" and
AND THE LIKE FOR CONTAINING ALIMENTARY AND OTHER SUBSTANCES
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This Invention relates to improvements in the construction and hermetic sealing
or closing of tin cans, canisters and the like for containing alimentary and other
-substances whereby the lid is so sealed or fastened to the can that it can be opened
by pulling a wire or its equivalent in a more easy manner than hitherto without
requiring the use of a separate opener.
In carrying out our Invention the sealing or closing may be effected either on
the top or on the upper edge of the side of the can or other vessel-the lid and the
can being formed with a rim or its equivalent in such a manner that a channel or
trough is left between the lid and the can at the joint. In this channel or trough
and all round the same we place a piece of cord, twine or other suitable packing
fitting between the rim of the can and the rim of the cover or lid. On this said
cord, twine or other packing we then place a piece of wire which passes all round
the channel or trough the end or ends projecting so as to give sufficient hold for
the fingers to pull upon when the can is to be opened. Solder is now run in and
passes on each side of the wire and attaches itself to the rim on the cover or lid
and to the rim on the can or canister. The cord or its equivalent acts as a kind
of packing under the wire and prevents the solder from passing under the wire and
attaching the cover directly to the body of the can or canister. In practice wo
have found one soldering sufficient.
In order to enable our Invention to be fully understood we will proceed to
describe the same by reference to the accompanying Drawing in which Figure 1, is
a sectional elevation of a tin can or canister constructed and hermetically scaled
according to our Invention the sealing or closing being effected on the top;
Figure 2, is a similar view shewing the sealing or closing effected on the upper edge
of the side of the can; Figure 3, is a plan of Figure 1, before soldering and
Figure 4, is an elevation of the can shewn in Figure 2, before soldering. Similar
letters in all the Figures represent similar parts.
a, represents the rim on the can A; b, the rim on the lid B, so as to leave when
the lid is applied to the can the channel c; d, is the packing of cord, twine or other
suitable material placed between the rims a, and b; e, is the wire which we place
on the packing d, the said wire passing all round the channel or trough c, and the
end projecting as shewn in Figures 3, and 4. The parts being in this position the
solder f, is now run in and passes on each side of the wire e, as shewn and
attaches itself to the rim b, on the cover or lid B, and to the rim a, on the can or
canister A.
To open a can or canister closed or sealed as hereinbefore described and shewn in
the Drawings it is merely necessary to pull the projecting end or ends of the wire e
and it can be readily stripped as the slight soldering at f, gives way easily and the
cover or lid B, can then be lifted off.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what
we claim is
Firstly. The method herein described of hermetically sealing tin cans, canisters
and the like containing alimentary and other substances by the employment of

page_text: suitable packing and a wire placed in a channel or trough between the lid and tho
can at the joint and soldered substantially in the manner and for the purposes
hereinbefore described and represented in the accompanying Drawing.
Secondly. In a tin can, canister or the like for containing alimentary and other
substances the combination of a channel or trough such as c, packing d, and wire e,
having a projecting end or ends substantially as and for the purposes set forth.
Thirdly. The manufacture and use of the improved tin cans, canisters or the like
hereinbefore described and represented in the accompanying Drawing.
