PROVISIONAL SPECIFICATION.
Improvements in Biscuit Tins or Boxes.
I, JOHN COLLINS of 20 Stockwell Place, in the City of Glasgow, Tin Box
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object the production of biscuit tins or boxes with the
seams or joints of the sides, ends and bottom turned inwards or concealed so as to
avoid obstruction and inconvenience in labeling such boxes as usually made with
projecting outside seams.
The bottom and two sides of the improved box are made of a single sheet of
tinned iron or other sheet metal, the edges of which have been previously folded
over, first inwards and then outwards so as to produce three plies or a treble
thickness at the edges. The end pieces which are made of separate sheets are each
bent over at right angles at their edges and these upturned edges of the end pieces
are inserted into the open slits between the folds of the piece forming the bottom
and sides of the box. When so fitted together the edges are closed and secured
by bumping or squeezing together the folds in a bumping or closing machine. In
lieu of forming the three ply fold on the edges of the bottom and sides it may be
formed on the edges of the end pieces in which case the edges of the sheet
forming the bottom and sides are bent over at right angles.

I, JOHN COLLINS, of 20 Stockwell Place, in the City of Glasgow, Tin Box
Manufacturer, 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 has for its object the production of biscuit tins or boxes with the
seams or joints of the sides, ends and bottoms turned inwards or concealed so as to
avoid obstruction and inconvenience in labeling such boxes as usually made with
projecting outside seams.
Figure 1 is a perspective view of a biscuit tin or box constructed in accordance
with my invention, and Figures 2, and 4 are details of modifications of the seams
or joints of same.
As shown particularly at Figures 1 and 2, the bottom A and two sides B, C, of
the improved box are made of a single sheet of tinned iron or other sheet metal,
the edges a, b and c of which have been previously folded over, first inwards and
then outwards so as to produce three plies or a treble thickness at the edges as
shown at Figure 2. The end pieces D, E, which are made of separate sheets are
each bent over at right angles at their edges d and e, and these upturned edges of
the end pieces D, E, are inserted into the open slits between the folds of the piece

page_text: forming the bottom A and sides B, C, of the box. When so fitted together the
edges are closed and secured by bumping or squeezing together the folds in a
bumping or closing machine.
In lieu of forming the three ply fold on the edges a, b, c, of the bottom A and
sides B, C, it may be formed on the edges d, e, of the end pieces D, E, as shown at
Figure 3, in which case the edges of the sheet forming the bottom A and sides B, C,
are bent over at right angles and inserted into the open slits formed on the end
pieces D and E.
The seams may be formed as shown at Figure 4, the result being the same as by
the formation shown at Figure 2, the edges of the sheet forming the sides and
bottom of the box being bent inwards only, and the edges of the end sheets being
bent inwards at right angles to the sheet and then outwards upon themselves. The
edges of the end sheets are then inserted in the open slits formed in the bottom
and sides.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
A biscuit tin or box having its seams or joints formed by folding and turning
inwards the meeting edges of the sheets in order to avoid obstruction and
inconvenience in labeling substantially as described with reference to the drawings
annexed.
Dated this 10th day of April 1895.
