IMPROVEMENTS IN CANISTERS OR. OTHER LIKE RECEPTACLES
Year: 1879

page_text: LETTERS PATENT to Charles Cheswright, of Parkhurst Road, in the County of
Middlesex, for the Invention of "IMPROVEMENTS IN CANISTERS OR. OTHER
LIKE RECEPTACLES."
Sealed the 18th November 1879, and dated the 4th September 1879.
PROVISIONAL SPECIFICATION left by the said Charles Cheswright at tho
Office of the Commissioners of Patents on the 4th September 1879.
CHARLES CHESWRIGHT, of Parkhurst Road, in the County of Middlesex. "IM-
PROVEMENTS IN CANISTERS OR OTHER LIKE RECEPTACLES."
My Invention relates to canisters or similar receptacles composed of lead, self
soldering metal, or any other suitable material or combinations of materials, and it
has for its object preventing the said canisters or receptacles from being fraudulently
opened without such fraudulent opening being detected.
In carrying out my Invention in order to effect this object I construct the upper
part or lid of the canister or receptacle of lead, self soldering, or other suitable
metal with a slight hollow protuberance extending above the same, the whole being
made out of one piece of metal by a punch and die, or otherwise, so as to have the
appearance of an embossed lid or capsule. The body and bottom of the canister or
receptacle may be made of the same material as the upper part or lid, or of a
different material as required, the bottom being soldered or otherwise attached after
the canister or receptacle has been filled. In order to open the canister or receptacle
it is requisite to sever the protuberance from the upper part or lid, and as it is
impossible to replace the same thereon detection is unavoidable in the event of the
canister or receptacle having been fraudulently opened.
The protuberance may be embossed and marked with any device or trade mark
in the usual manner. It may also be perforated when required for certain descrip-
tions of goods at the point of severance of the protuberance from the upper part of
the canister.

PROVEMENTS IN CANISTERS OR OTHER LIKE RECEPTACLES."
"IM-
My said Invention relates to canisters or similar receptacles composed of lead,
self soldering metal, or any other suitable material or combinations of materials ;
and it has for its object preventing the said canisters or receptacles from being
fraudulently opened without such fraudulent opening being detected.
In carrying out my said Invention in order to effect this object I construct the
upper part or lid of the canister or receptacle of lead, self soldering, or other suitable
metal, with a slight hollow protuberance or crown above the same, the whole being
made out of one piece of metal by a punch and die or otherwise so as to have the
appearance of an embossed lid or capsule. The body and bottom of the canister or
receptacle may be made of the same material as the upper part or lid, or of a
different material, as required, the bottom being soldered or otherwise attached after
the canister or receptacle has been filled.
It is preferred however to make the entire canister out of one piece of metal cut
to a suitable shape, and afterwards bent up into the required form of the canister,
and soldered or otherwise secured at its edges. In this case the metal is embossed
with any suitable pattern or colored throughout its entire surface before it is bent
up into the form of the canister, and in any case the protuberance or crown should
be embossed and marked with any device or trademark in the usual manner.
The accompanying Drawing illustrates a canister constructed according to the
said Invention, Figure 1 being a perspective view of the canister; and Figure 2, a
vertical section of the same...
The canister is assumed to have been made out of a single piece of metal, cut and
bent into the requisite shape, with the edges soldered together so as to form the
upper part or lid A, the body B, and bottom C, the latter, being left unsoldered; as
shewn by dotted lines in Figure 2, until the canister has been filled.
The entire external surface of the metal is also assumed to have been embossed
or colored in the manner before referred to, although not shewn so in the Drawing.
Dis the hollow protuberance or crown formed in the upper part or lid A by a
punch and die or otherwise, and intended to be embossed or marked with a device
or trade mark so as to have the appearance of an embossed capsule.
The canister having been filled with the articles or substance which it is required
to contain is secured by soldering or otherwise uniting the edges of the bottom C
to the body B. In order to open the canister it is requisite to sever the pro-
tuberance or crown D from the upper part or lid A along the line a, a, Figure 2,
and as from the limited depth of the protuberance or crown D it is impossible to
replace the same on the lid, detection is unavoidable in the event of the canister or
receptacle having been fraudulently opened. When moreover the entire canister
is made of metal and colored or embossed in the event of the lid, or bottom, or one
of the sides, or a portion thereof, being fraudulently removed it will not be possible
to replace it or substitute another part therefore without its being discovered that
the canister has been tampered with, as the colored or embossed portion removed
cannot be replaced or reproduced so as to merge into or match with the remaining
portions, and detection must unavoidably ensue.
When the canister or receptacle is used for goods which do not admit of a
hermetic closure it may be formed with perforations, and such perforations may
conveniently be made at the point of severance a, a, of the protuberance or crown D
from the upper part or lid-A.
Having now described and particularly ascertained the nature of my said Inven⚫
tion, and the manner in which the same is or may be used or carried into effect, I

page_text: will observe in conclusion that what I consider to be novel and original and
therefore claim as the Invention secured to me by the herein before in part recited
Letters Patent is,―
First. A protective canister or receptacle the upper part or lid of which (made in
one piece) is formed with an embossed hollow protuberance or crown, substantially
as and for the purpose hereinbefore described.
Second. A protective canister or receptacle made entirely of colored or embossed
metal, and having the upper part or lid (in one piece) formed with an embossed
hollow protuberance or crown, substantially as and for the purpose herein before
described.
In witness whereof, I, the said Charles Cheswright, have to this my Specifi-
cation set my hand and seal, this First day of March, 'One thousand eight
. hundred and eighty.
