PROVISIONAL SPECIFICATION.
Improvements in or connected with Sheet Metal Boxes.
We, JOHN THOMSON PAUL and JAMES PAUL, both of Grove Works, Brandfield'
Street, Edinburgh, in the County of Midlothian, North Britain, Lamp Manu--
facturers, do hereby declare the nature of this invention to be as follows:
This invention relates more especially to boxes in which biscuits or other articles
are imported, and has for its object to so construct the box that it can be easily
opened and without the aid of any instrument for that purpose.
The invention consists in having a piece of wire all round the inside of the lid or
cover of the box, and the edges of the lid are bent or turned inward so as to keep
the wire in position. The lid is soldered to the top of the box, and one end of the
wire projects out a little and has a small knob or handle attached to it, so that
when the box is to be opened the knob is held in the hand, and the wire rips open
the lid.

WILL BE Metal Boxes.
We, JOHN THомSON PAUL and JAMES PAUL, both of Grove Works, Brandfield
Street, Edinburgh, in the County of Midlothian, North Britain, Lamp Manu-
facturers, 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 :-
Our invention relates to an improved method of opening tin boxes, tins or cases,
and has for its object to provide a means by which the tin box, tin or case can be
easily opened without the aid of an instrument.
In order that our invention may be properly understood and readily carried into
effect we have hereunto appended two explanatory sheets of drawings in the several
figures of which corresponding parts are marked with the same letters of reference.
Figure 1 represents a section of a box or tin with the wire attached to the lid in
the manner to be adopted in tins containing fluids or liquids.
Figure 2 is a plan of the same.
Figure 3 is a similar view to Figure 1 showing the wire attached to a box or tin
in which solids are contained.
In carrying out our invention with reference to Figures 1 and 2, we provide a
strong fine wire a, preferably of steel, which runs all round the inside of the inner
rim 6 of the lid or cover of the box or case, which is made cup-shaped to keep the
wire in position. Both ends of the wire are brought out through a small hole c in
the cover, one end being soldered to the cover while the other terminates in a
loop d. When the box or tin is to be opened it is held in one hand while the loop
is taken in the other and pulled in an upward direction, and the wire easily rips the
inner rim of the cover all round.
In the arrangement shown at Figure 3, with reference to boxes or tins for
containing solids, the side of the box or tin near the top is bent over the wire all

round the circumference of the box, and the lid is soldered on the top of the side
When the box is to be opened the wire is firmly pulled, and it then cuts th
all round where it is placed.
Having now particularly described and ascertained the nature
tion and in what manner the same is to be performed, we decl
