Improvements in the Sealing and Unsealing of Cans or Vessels for
the Preservation of Meats, Vegetables, and other Perishable
Commodities Airtight.
I, JOHN MOGINIE CHAMBERS, of Thimblemill House, Smethwick, in the
County of Stafford, Engineer, do hereby declare the nature of this invention (a
communication to me from abroad from Thomas Moore Bryant, of Auckland, in
the Colony of New Zealand, Merchant,) to be as follows:-
This invention relates to cans or other metallic receptacles for containing and
preserving meat, fish, fruit, and other perishable commodities, and consists of
improved means for closing or sealing such vessels and for facilitating the opening
thereof.
According to the improved mode of manufacture, the subject of the present
invention, a piece of wire is inserted in the space between the dished edge of the
cover and the body of the receptacle and then soldered; a loop being left outside
the solder for engagement with a hook or other suitable instrument when it is
desired to open the vessel. The space between the edge of the cover and the body
of the receptacle should be only sufficient in width to receive the wire by pressure
so that when in position in the said space, the wire will be retained between the
outer surface of the lid flange and the inner surface of the vessel's body during
the operation of soldering, additional strength and solidity being at the same time
afforded to the joint.
The goods with which the receptacle is to be filled are preferably inserted
from the bottom, and when the receptacle has been charged to the required
extent, closure is effected in the usual manner by hand or with the aid of mechanical
appliances. The receptacle may however be filled from the top if preferred and
the cover applied and secured as above described.
In order to open the can or receptacle, it is merely necessary to engage the loop
formed at one extremity of the wire with a hook or other suitable instrument and
then to pull the wire, thereby cutting the solder and freeing the cover.

County of Stafford, Engineer, do hereby declare the nature of this invention (a
communication to me from abroad from Thomas Moore Bryant, of Auckland, in
the Colony of New Zealand, Merchant,) and 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 cans or other metallic receptacles for containing and
preserving meat, fish, fruit, and other commodities or substances, and consists of
improved means for closing or sealing such vessels and for facilitating the opening
thereof

page_text: According to the improved mode of manufacture the subject of the present
invention, a piece of wire is inserted in the space between the dished edge of the
cover and the body of the receptacle and then soldered; a loop being left outside
the solder for engagement with a hook or other suitable instrument when it is
desired to open the vessel. The space between the edge of the cover and the body
of the receptacle should only be sufficient in width to receive the wire by pressure,
so that, when in position in the said space, the wire will be retained between the
outer surface of the lid-flange and the inner surface of the body of the vessel during
the operation of soldering; additional strength and solidity being at the same time
afforded to the joint.
The goods with which the receptacle is to be filled are preferably inserted from
the bottom, and, when the receptacle has been charged to the required extent,
closure is effected in the usual mauner by hand or with the aid of mechanical
appliances. The receptacle may, however, be filled from the top, if preferred,
and the cover applied and secured as above described.
In order to open the can or receptacle, it is merely necessary to engage the loop
formed at one extremity of the wire with a hook or other suitable instrument and
then to pull the wire, thereby cutting the solder and freeing the cover.
A can or vessel sealed in accordance with this invention is represented in the
accompanying diagrams, whereof Fig. 1 is a plan and Fig. 2 a vertical section.
A is the body of the vessel, B the top of the vessel, C the bottom thereof,
and D the wire soldered in between the lid-flange and the inner surface of the
body A.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I claim :-
-
1. For the preservation of meat, fish, fruit, vegetables and other commodities or
substances, a can or vessel sealed substantially as herein described, the joint being
soldered and containing a wire which serves both to strengthen and solidify the
joint and to afford means for unsealing the can or vessel.
2. The improved method of unsealing a hermetically-closed can or vessel,
substantially as herein described, and consisting in cutting the solder by means of a
wire contained in the joint.
