PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Tin Canisters and the like.
I, ALBERT EDWARD BENTLEY, of the Firm of John Bentley, of Rodney Street
Tin Works, Oldham Road, Manchester, in the County of Lancaster, Tin Plate
Worker, do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of tins or canisters .cf a rectangular
form in horizontal section either with square, rounded or bevilled corners, the
object of the invention being to enable such tins or canisters to be closed in a
secure air tight manner by means of a lid or top which can only be removed by
leverage, such for example as described in the Specification of Letters Patent
granted to John Bentley, No. 7663 dated June 24th, 1885.
For the purposes of my invention I make in the top of the said rectangular box
an opening of an oval or elliptical form, the sides or ends (or both) of which just
touch the sides and ends of the box, or nearly so, and by means of dies I raise
an oval or elliptical neck or doubled flange all round such opening the mouth being
slightly conical, and I form a corresponding lid or cover of such material with
a downward projecting flange, also slightly conical, so as to fit tight into the oval
or elliptical neck and having a projecting flange all round the top by means of
which it can be raised by leverage say as described in the above specification.
By these means I combine with the rectangular form of canister or tin which is
most convenient for packing and storage, the benefits of the air tight fitting lid
or cover, and at the same time I afford greater facility for filling and removing
the contents of the canister than could have been obtained by any other form,
it not being possible to make the lever lid to keep air-tight if made with flat
sides to follow the form of the box.
Dated this 22nd day of December 1896.

Improvements in the Manufacture of Tin Canisters and the like.
I, ALBERT EDWARD BENTLEY, of the Firm of John Bentley, of Rodney Street
Tin Works, Oldham Road, Manchester, in the County of Lancaster, Tinplate
Worker, 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 the manufacture of tins or canisters of a rectangular
form in horizontal section either with square, rounded or bevilled corners, the

page_text: object of the invention being to enable such tins or canisters to be closed in a
secure airtight manner by means of a lid or top which can only be removed by
leverage such for example as are described in the Specification of Letters Patent
granted to John Bentley No, 7,663 dated June 24th, 1885.
The nature of my said invention and the manner in which the same is to be
performed will be readily understood on reference to the annexed sheet of draw-
ings and the following explanation thereof."
Fig. 1 on the drawing is a vertical section through a tin canister and lid made
according to my invention and Fig. 2 is a plan view of the same with the lid
removed, and Fig. 3 a plan view of the lid detached.
For the purposes of my invention I make in the top of the said rectangular box a
an opening of an oval or elliptical form the sides or ends (or both) of which
just touch the sides and ends of the box a or nearly so, and by means of dies I
raise an oval or elliptical neck or doubled flange call round such opening the
mouth being slightly conical, and I form a corresponding lid or cover d of such
material with a downward projecting flange e also slightly conical so as to fit
tight into the oval or elliptical neck c and having a projecting flange d all round
the top by means of which it can be raised by leverage as described in the above
specification.
By these means I combine with the rectangular form of canister or tin which is
most convenient for packing and storage, the benefits of the air tight fitting lid
or cover and at the same time I afford greater facility for filling and removing
the contents of the canister than could have been obtained by any other form,
it not being possible to make the lever lid to keep air-tight if made with flat sides
to follow the form of the box as hitherto practised.
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:
The combination with a rectangular formed tin canister or the like of an
elliptical opening or neck made slightly conical and a corresponding elliptical
lip made to fit therein and provided with a projecting flange all round by means
of which it can be raised or prized open by leverage, substantially as hereinbefore
described and illustrated by the drawings annexed.
