Improvements in or relating to Hermetically Sealed Sheet Metal
Boxes or Receptacles for Food, Tobacco, or other like purposes.
We, RODERICK JAMES FRY, of Barclay & Fry, Limited, The Grove, Southwark,
London, and BARCLAY & FRY LIMITED, of The Grove, Southwark, London,
aforesaid, do hereby declare the nature of this invention to be as follows:-
This invention relates to cans or sheet metal boxes or the like especially of the
character in which such cans metal boxes etc. are provided with an inner cover
and an outer lid i.e. cans or boxes provided with a very thin tagger tin or other
suitable cover (which for the sake of brevity will hereinafter be referred to as the
cover") hermetically secured thereon and a loose or removable lid or outer cover
(which will hereinafter be referred to as the "lid") adapted to fit more or less
closely (or otherwise) over said cover or more or less closely over the mouth of
the can or vessel after said cover has been cut out.

According to the present invention the tin or sheet metal box can canister or
other receptacle is provided with a cover of tagger tin or other suitable sheet
metal and this tin etc. is formed and said inner cover hermetically sealed thereon
in any well-known or suitable manner-except that at one point a recess indenta-
tion or in-set is formed (on the exterior) in the side at the top but in suchwise
that the hermetic seal of the tin is not affected by this inset recess or indentation.
The outer lid is provided with a cutter of any suitable character adapted to
pierce and cut open the said inner cover of tagger tin etc. such cutter being
for instance formed separately and attached or affixed to the lid in any suitable
manner or said cutter may advantageously be formed integrally with and out of
the lid for instance by slitting the top part of said lid (near its edge) on two sides
of a triangle (i.e. a more or less V-shaped slit) and the more or less V-shaped
tooth thus formed is then bent down at right angles to the plane of the top of the
lid and thus forms the cutter-the position of this cutter being sufficiently near
the edge of the outer lid or such that it (the cutter) will enter the aforesaid inset
or recess in the side of the can body when the outer "lid" is applied to said can
and so protect and prevent the cutter from piercing or cutting the inner "cover"
until desired whereupon the outer lid is lifted off or raised and then applied to the
can body with the cutter otherwise than over said recess or inset on the can body
whereupon said cutter will pierce the inner cover and then by moving the lid
round with respect to the can body (or vice versa) thereupon the inner cover is
cut out.

We, RODERICK JAMES FRY, of Barclay & Fry Limited, The Grove, Southwark,
London, and BARCLAY & FRY LIMITED, of The Grove, Southwark, London,
aforesaid, do hereby declare the nature of this invention to be as follows:-
This invention relates to cans or sheet metal boxes or the like-especially. of the
character in which such cans metal boxes etc. are provided with an inner cover
and an outer lid i.e. cans or boxes provided with a very thin tagger tin or other
suitable cover (which for the sake of brevity will hereinafter be referred to as the

(which will hereinafter be referred to as the "lid") adapted to fit more or less
closely (or otherwise) over said cover or more or less closely over the mouth of
the can or vessel after said cover has been cut out.
According to the present invention. the tin or sheet metal box can canister or
other receptacle is provided with a cover of tagger tin or other suitable sheet
metal and this tin etc. is formed and said inner cover hermetically sealed thereon
in any well-known or suitable manner-except that at one point à recess indenta-
tion or inset is formed (on the exterior) in the side at the top but in suchwise
that the hermetic seal of the tin etc. is not affected by this inset recess or indenta-
tion.

The outer "lid" is provided with a cutter of any suitable character adapted to
pierce and cut open the said inner". cover of tagger tin etc. such cutter being
for instance formed separately and attached or affixed to the lid in any suitable
manner or said cutter may advantageously be formed integrally with and out of
the lid for instance by slitting the top part of said lid (near its edge) on two sides
of a triangle (ie. a more or less V-shaped slit) and the more or less V-shaped
tooth thus formed is then bent down at right angles to the plane of the top of the
lid and thus forms the cutter the position of said cutter being sufficiently near
the edge of the outer lid or such that it (the cutter) will enter the aforesaid inset
or recess in the side of the can body when the outer "lid" is applied to said can
before use (i.e. before it is desired to open said can or box) and so protect and
prevent the cutter from piercing or cutting the inner cover "until desired
whereupon the outer lid is lifted off or raised and then applied to the can body
with the cutter otherwise than over said recess or inset on the can body whereupon
said cutter will pierce the inner cover and then by moving the lid round with
respect to the can body (or vice versa) thereupon the inner cover is cut out.
Referring to the accompanying.drawings:-
:-
Fig. 1 is a plan of a circular box (with the outer lid removed) with inner cover
hermetically sealed thereon showing the recess or inset a* (according to the
present invention) on the side of the box at the top edge thereof.
Fig. 2 is a vertical cross sectional view on line 2-2 Fig. 1.
Fig. 3 is a vertical cross sectional view of the separate outer lid on line 3-3
Fig. 4.
Fig. 4 is a plan of the outer lid.
Fig. 5 is a vertical cross-sectional view similar to Fig. 2 showing the outer lid
in position with the cutter thereon in the recess or inset according to the present
invention.
Fig. 6 is similar view to Fig. 5 showing the cutter removed from the recess
and driven through the inner cover to cut the latter open.

page_text: a 18 the body or the metal box or can.
b is the bottom thereof
c is the inner cover of thin tagger tin or other suitable material which is
soldered or otherwise suitably secured to the body a.
a* is the recess or inset which is formed according to the present invention in
the body or side a of the box.
d is the outer cover or loose lid provided with a cutter for cutting open the
inner cover c; in the case illustrated this lid d is provided with cutter & formed
integrally out of the substance of the lid itself by making a V-shaped slit in the
lid near the edge see Fig. 4 and pressing down the cutter thus formed into the
cutting position (shown in Figs. 3 and 5) ready for use.
The operation is as follows:-
When the can or box has been sealed or closed by means of the inner cover c
thereupon the loose outer lid d can be safely placed thereover by inserting the
cutter in the recess a* (as shown in Fig. 5) and thereby such cutter dis
protected and prevented from injuring the inner cover c.
When it is desired to open the box the lid d is removed or raised and the
cutter brought into position over the inner cover c other than over the recess
or inset a and thereupon by forcing down the lid the cutter will be driven
through the inner cover c (for instance as shown in Fig. 6) and then by revolving
the lid d with respect to the body a or vice-versa thereby the inner cover c will be
cut out or cut open.
.
Figs. 7 and 8 show a slightly modified construction of a circular metal box made
according to our present invention Fig. 7 being a plan with part of the outer lid
removed to show the recess and Fig. 8 being cross section on line 8-8 Fig. 7.
As will be seen on reference to said Figs. 7 and 8 the recess a³ is made rather
smaller than that shown in the other figures of the drawings.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. In sheet metal boxes cans or the like having an inner cover and an outer
or loose lid provided with a cutter thereon for cutting open said inner cover--
constructing the body of said box or can with an inset recess or indentation on
the side edge thereof adapted to receive therein the aforesaid cutter in such wise
that the latter will lie in said recess or inset and be prevented from cutting or
entering the inner lid until desired substantially as herein before set forth.
2. Sheet metal boxes or receptacles or the like constructed with an inset as
hereinbefore set forth and combined and arranged to act in conjunction with a
loose outer cover provided with a cutter thereon ready for cutting open the inner
cover substantially in the manner and for the purposes herein before described and
illustrated in the drawings hereunto annexed.
