Improvements in Cans for Packing Tobacco and other Commodities.
I, MILTON E. MARCUSE, of Richmond, in the County of Henrico, State of
Virginia, United States of America, Gentleman, 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:-
In
My invention is an improved can for use in packing tobacco and other com-
modities. The desiderata of such cans are cheapness, strength, rigidity, close-
sealing and security of fastening of the lids or covers, along with adaption for
convenient detachment of the same for access to the contents of the cans.
embodying these qualities and features I have adapted the improved construction
and combination of parts hereinafter described, and shown in the accompanying
drawings, in which.
Figure 1 is a perspective view of the can.
Figure 2 is a perspective view of the can, showing the cover removed.
Figure 3 is an enlarged vertical section of the top portion of the can.
Figure 4 is a plan view of the sheet from which the body of the can is formed.
Figure 5 is a detail section illustrating the construction of the body of the
çan.
Figure 6 is a perspective view illustrating the application of a tool in forming
loops on the can body.
Figure 7 is a perspective view of the said tool.
My invention pertains mainly to the construction of the body of the can and
to the means of attachment of the lid or cover thereto.
The body A is constructed from a single piece a. Figure 4, of sheet metal,
preferably tinned iron, is which piece two, three or more slits a' are cut in the

in bending or doubling the top portion of such body or piece a upon itself, thus
forming a lap or fold a², as shown in Figures 2, 3 and 5. In such operation the
double edge d is bent inward to form a narrow horizontal shoulder or flange.
The next step consists in curving such flanged piece a into circular shape,
Figure 5, as required to form the body of a can. A suitable pointed tool,
Figures 6 and 7, is then inserted in the slits a¹ to bend outward the subjacent
portions of the lap or fold a³, so as to form loops a³ for secure attachment of the
cover B.
The cover B is cut out as one piece, with lugs or tongues 6 attached, from a
flat metal sheet and formed up in dies into the required shape. (Shown in
Figure 5). These tongues b are spaced apart like the loops a³ of the can-body
and are adapted to pass through the latter. When the cover B is applied to the
body a of the can, its lugs or tongues 6 enter the slits a¹ and project through the
same and below the edge of the body lap or fold a². The double inturned flange
serves as a bed for an elastic packing-ring e, which is laid thereon preparatory to
applying the cover B. When the tongues bare bent up, they clasp and lock
over the loops a³, as shown in Figure 1. It is obvious that the cover Bia
thereby locked securely, as well as hermetically closed.

page_text: It will be seen that the formation of the loops a³ integrally with the integral
lap a¹ of the can-body a and the similar formation of the lugs or tongues b
relative to the body of the cover B effects a considerable economy in manufacture
and a great security and durability of fastening or connection between the parts.
The can is also rendered very strong and durable as a whole.**
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. A sheet metal can comprising a suitable body portion, the material of
which is bent over upon itself to form a double thickness at the upper end
of the can, and extending down a short distance below the said upper edge thereof
and the outer thickness of the metal being provided with apertures at suitable
points around the can, in combination with a removable cover, which latter is
formed with tongues which are-designed to extend through the apertures in the
-body of the can and then be turned- up to draw the cover tightly downward and
hold the same in such position, substantially as described.
2. A sheet metal can comprising a suitable body-portion, the material of which
is bent over upon itself to form a double thickness at the upper end of the can,
and extending down a short distance below the said upper edge thereof, the
double portion being turned inwardly all around at the upper edge of the can to
form a seat for a packing strip, and the outer thickness of the metal being
provided with apertures at suitable points around the can, in combination with
a removable cover, which latter is formed with tongues which are designed to
extend through the apertures in the body of the can and then be turned up to
draw the cover tightly in contact with the packing strip and hold it in such
position, the body portion of the can being made of a single piece of material and
the cover of the can being also made of a single piece of material, substantially
as described.
