Improvements in or relating to Tins and Soldered Metal.
Receptacles.
I CONSTANT HENDRIK HUMMELINCK of Vlaardingen, in the Kingdom of Holland,
Manufacturer, do hereby declare the nature of this invention to be as follows
This invention relates to metal receptacles such as soldered tins or cans for the
preservation of articles of food or other goods, and it consists in arranging a wire in
relation to the soldered joint or joints, at which the tin or the like is to be opened,
said wire having a projecting end by which it may be grasped by the hand or by a
suitable tool, so that by pulling such projecting end, the wire may be drawn up or
out so as to cut or break the solder at such joint and so unclose the joint. The
wire may be laid over or along the adjacent edges or parts before soldering, the solder
being placed over such wire retaining the same in place and closing the joint. The
projecting end of wire may be formed into a loop.

Improvements in or relating to Tins and Soldered Metal
Receptacles.
I CONSTANT HENDRIK HUMMELINCK of. Vlaardingen in the Kingdom of Holland
Manufacturer, 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 relates to metal receptacles or vessels such as soldered tins or cans
for the preservation of articles of food or other goods and which require to be opened
by the cutting of the tin or metal or the breaking or unfastening of the solder
connecting the parts. The improvements mainly consist in providing within or
under the soldered jointing of the lid and body of the vessel or at such other
soldered seam as may be desired to be opened or disconnected, a wire in such a
manner that the same may be pulled to act as a cutter or opener for said joint
or seam.
The accompanying drawings shows the invention as applied to the lid or end of a
cylindrical can or tin, of a shape such as is usually employed for preserving condensed
milk or other tinned or canned good.
Fig. 1 shows the tin closed-Fig. 2 in perspective the tin after it is opened Fig. 3
is a sectional view of the seam with wire when closed-Fig. 4 is a similar view showing
the seam opened.
In carrying the invention into effect I prefer to make a depressed channel a along
the edge of that part which is to be the under or inner face or side of the seam, in
this case the upper rim of the body A of the vessel and I turn up the edge sufficiently
to press firmly against the other part, here the rim of the lid B so that the contents of the
vessel cannot come in contact with the wire b in the channel-The wire is laid round
in the channel a preferably around the whole circumference or nearly so, or along the
whole length of the seam if it be a straight one. One end of the wire is caused to
project as in Fig. 1 being preferably made into a loop-Having laid in the wire, the
lid is put on, the rim thereof -being bent down to-cover the wire as in Fig. 3, and
solder is applied to fasten down the rim onto the body of the vessel in the known
manner. Cans or tins so made may be filled and closed in the usual way. By pulling
the projecting end of the wire, the latter cuts open the seam by tearing the rim of
the lid or by in some cases breaking the solder according to which may be the weakest,
and the tin is opened substantially as in Fig. 2.

page_text: Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed I declare that wha
I claim is;-
1). The provision in a seam of a soldered "tin" or vessel, of a wire adapted to open
or break said seam substantially as set forth.
'
2). In combination with the wire for the purpose described, the seam with channel a
constructed substantially as illustrated and set forth.
