PROVISIONAL SPECIFICATION.
Improvements in Cans.
I, GEORGE WILLIAM CLERIHEW, of No. 47 Cowan Avenue, in the city of
Toronto, in the County of York and Province of Ontario, Dominion of Canada,
Commercial Traveller, do hereby declare the nature of this invention to be as
follows:
The object of my invention is to provide a can that will be more perfect and
in the manufacture whereof less time will be consumed than has been possible
heretofore.
To these ends, the invention may be said, briefly, to consist in providing the
cover of the body of a key opening can with an intact detachable strip having a
laterally projecting tongue section, and demarcated by a single weakened portion
or weakening line extending preferably in parallel line to the edge of the cover.
The body of the can body may be of any approved construction, but preferably
has a bead upon which the lower edge of the cover may rest.
The periphery of the cover is turned down in order to provide a retaining flange
which is formed with outwardly projecting bead having a single continuous
weakened portion extending in a continuous line completely around said bead
preferably at the apex thereof and parallel to the edge of said flange, thus
forming an intact detachable strip of even thickness and uniform strength
throughout. A tongue section is formed in one with the lower edge of this strip
and extends, preferably laterally at an acute angle thereto.
The cover thus formed may be secured to the body of the can, as usual, by
soldering, and to remove the cover, any one of the well known forms of slotted
keys may be fitted over the tongue section and turned with the result that such
tongue section will be first wound thereon and then as the key continues to be
turned the strip will be torn transversely thereof to the single weakening line
where the line of tearing will be diverted and follow said weakening line until
the strip is detached and the cover removed.
The strip tears in a straight line owing to the outwardly inclined lower portion
of the bead.

page_text: I, GEORGE WILLIAM CLERIBEW, of No. 47 Cowan Avenue, in the City of
Toronto, in the County of York and Province of Ontario, Dominion of Canada,
Commercial Traveller, 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: ---
The object of my invention is to provide a can that will be more perfect and
in the manufacture whereof, less time will be consumed than has been possible
heretofore.
To these ends, the invention may be said, briefly, to consist in providing the
cover of the body of a key opening can with an intact detachable strip having a
laterally projecting tongue section, and demarcated by a single weakened portion
or weakening line extending preferably in parallel line to the edge of the cover.
For full comprehension, however, of the invention, reference must be had to
the accompanying drawings forming a part of this specification, in which like
symbols indicate the same parts, and wherein,
Figure 1 is a side elevation of a can constructed according to my invention;
Fig. 2 is an enlarged transverse vertical sectional view thereof taken on line 2, 2,
Fig. 1 and
Fig. 3 an enlarged detail sectional perspective view thereof.
The body b of the can body may be of any approved construction, but preferably
has a bead b¹, upon which the lower edge of the cover, c, may rest.
The periphery of this cover is turned down in order to provide a retaining
flange c¹, which is formed with outwardly projecting bead c, having a single
continuous weakened portion, c2, extending in a continuous line completely around
said head, preferably at the apex thereof and parallel to the edge of said flange,
thus forming an intact detachable strip, 3, of even thickness and uniform strength
throughout. A tongue section, c, is formed in one with the lower edge of this
strip and extends, preferably laterally at an acute angle thereto.
The cover thus formed may be secured to the body of the can, as usual, by
soldering, and to remove the cover, any one of the well known forms of slotted
keys may be fitted over the tongue section and turned with the result that such
tongue section will be first wound thereon and then as the key continues to be
turned the strip will be torn transversely thereof, as shown in an exaggerated
manner in Fig. 3 to the single weakening line where the line of tearing will
be diverted and follow said weakening line until the strip is detached and the
cover removed.
The strip tears in a straight line owing to the outwardly inclined lower portion
of the bead c³.
In constructing cans according to any invention they may be manufactured
more quickly and therefore at & reduced cost than heretofore, and when completed
more perfect articles will be produced in that the danger of leakage caused by the
accidental starting of a tear across the retaining strip will be obviated owing to
such strip being of as great strength adjacent to the projecting tongue as at
any other point.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is:-
1. In combination with a can body and a removable cover therefor.—a strin

page_text: detachably connecting said cover and body together and said strip being of even
thickness throughout, for the purpose set forth.
2. In combination with a can body b and a removable cover c therefor having
the periphery thereof turned down to form a flange ca strip of uniform
strength throughout detachably connected to said cover by a single weakened
portion, c², extending in a continuous line parallel to the lower edge of said strip,
and a tongue section, c, formed in one wirl said strip, substantially as set forth.
3. In combination with a can body and a removable cover therefor,—a strip
detachably connecting said cover and body together, said strip being intact and
of uniform strength throughout, and having a laterally projecting tongue section
formed in one therewith, for the purpose set forth.
4. In combination with a can body, and a removable cover therefor, a strip
detachably connecting said cover and body together, said strip being of uniform
strength throughout, and the portion of said strip adjacent to its point of connec-
tion to said cover or body being outwardly inclined, for the purpose set forth.
5. In combination with a can body and a removable cover therefor having the
periphery thereof turned down to form a flange,--an outwardly projecting bead
formed upon said flange parallel to the lower edge of said flange, a continuous
weakened portion extending in a continuous line around the apex of said bead
and a tongue section formed in one with the lower edge of said flange, substan-
tially as and for the purpose set forth.
