I, FREEMAN PAYZANT, of Lockeport, County of Shelburne, Province of Nova
Scotia, Canada, 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 an improvement in solderless cans, and its object is to
provide a can, the body-portion of which is seamless and having a cover secured
thereto by a solderless joint, whereby the can is especially adapted for canning
fish and other perishable substances.
To these ends, the invention consists in a seamless and solderless can, constructed
substantially as hereinafter illustrated and described and defined in the appended
claims.
Referring to the drawings, in which similar numerals of reference indicate
similar parts,
Figure 1 is a perspective view of a can, constructed in accordance with this
invention.
Figure 2 is a similar view of the cover.
Figure 3 is a sectional view.
In the drawings, 1 designates the body of the can, which is stamped up from a
sheet of metal into the desired shape. The body-portion of the can thus formed
is without seams, and the bottom portion is integral with the body-portion also
without seams, the entire body-portion and bottom portion being formed of a
single integral sheet of metal without seams or joints of any description. An
annular flange (2) is formed integral with the upper edge of the body-portion
during the process of stamping up the body-portion.
Any form of cover preferred may be used in connection with the seamless body-
portion, which cover may be secured thereto by any usual or preferred form of
solderless joint, but in the drawings is shown a cover (3), preferably formed of a
single piece of material having its outer edges bent upwardly as at (4), and then
outwardly as at (5), forming an offset portion. Around the outer periphery of the
upwardly extending portion (4) is placed a wire strip (6), having its end portions
extending through an opening (7) formed in the cover, a drop of solder serving
to hold the strip in position.
In assembling the parts, the fish is first placed in the body-portion, and a
suitable washer (8), preferably formed of paper, is placed on the flange (2). The
cover is then laid on the washer, after which the outwardly extending portion (5)
is bent downwardly as best shown in Figure (3), the lower edge of the portion (5)
being below the plane of the flange (2) and necessarily below the plane of the
main portion of the cover. The lower edge is then bent under the flange (2),
forming a sealed connection. The usual process of boiling, etc., afterwards takes
place, and the can is ready for shipment.
When it is desired to open the can, the exposed end portions of the wire strip (6)
are drawn through the cover, cutting the top out in a neat manner.

page_text: By this construction it will be readily seen that the cover, resting on the
flange (2) or the washer (8), will be held firmly in position and there will be no
liability of the top being crushed in, while by the use of the upwardly extending
portion (4) and the portion (5), an annular recess will be formed, for the reception
of the opening wire (6), at a point where there is no liability of the contents
coming in contact with the wire.
In addition to this, the cutting of the cover by the wire will be at a point where
the effect of the cutting will be to allow the retaining flange to drop off, while
the central portion can be lifted off, thus leaving the body-portion clear of the
cover and suitable for use as an ordinary tin. The upwardly extending portion
also serves to form a support for the can when turned upside down.
It is obvious, that instead of having the opening wire in the cover, it may be
arranged in the bottom, being held in place by a crimp formed therein when
stamping up the body-portion.
The advantages of this construction are many, and are thought to have been
clearly set forth.
While I have herein shown a preferred form of carrying my invention into
effect, yet I do not desire to limit myself to such preferred details of construction,
but claim the right to use any and all modifications thereof which will serve to
carry into effect the objects to be attained by this invention in so far as such
modifications and changes may fall within the spirit and scope of my said invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
-
1. As an new article of manfacture for the preserving of fish and other sub-
stances of a perishable nature, a seamless and solderless can, comprising a body-
portion and a bottom portion formed from a single integral sheet of metal, and
à cover adapted to be secured to said body-portion, by means of a solderless joint,
substantially as described.
2. A seamless and solderless can, comprising a body-portion; a bottom portion
integral therewith; an annular flange integral with the upper edge of said body-
portion; and a cover adapted to be secured to said body-portion, by means of a
solderless joint, substantially as described.
