PROVISIONAL SPECIFICATION.
Improvement in Biscuit Tins and similar Boxes.
I, JOHN COLLINS, 75 Brunswick Street, in the City of Glasgow, Tin Box
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention which relates to biscuit tins and similar boxes has for its object
the provision of means for ensuring that such tins or boxes will be maintained air-
tight.
To that end I employ a band or ring of rubber, cloth or other packing which I
fit around the upper edge of the box, so that when the lid is applied it bears against
the band or ring and is held air tight. The lid is preferably dished or formed with
a groove or recess around its edge so that when fitted over the box it bears both
against the inside of the box and on the packing band or ring on the outside of the
box, the outer turned over edge or flange of the lid being pressed hard against the
packing by machine or by hand.
In boxes in which the recess or groove is formed in the edges of the box to
receive a single flange or turned over edge on the lid, the ring or band of rubber or
other packing material is fitted on the lid instead of on the box. In cases in which
the recess or groove is made both in the lid and in the body of the box a ring or
band of packing material may be applied to both.
The box may be made round square, oblong or of other shape.
A bend is or may be formed around the sides of the box in proximity to the lid
to facilitate pressing open of the turned over edge by the use of a knife or like
instrument.

COMPLETE SPECIFICATION.
Improvement in Biscuit Tins and similar Boxes.
I, JOHN COLLINS, 20 Stockwell Place, late of 75 Brunswick Street, 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 which relates to biscuit tins and similar boxes has for its object
the provision of means for ensuring that such tins or boxes will be maintained air-
tight. As represented in the accompanying drawings of a biscuit tin or box in
vertical section at Figure 1 and in inverted plan of the lid at Figure 2, I employ
a band or ring of rubber, cloth or other packing A which I fit around the upper
edge of the box B, so that when the lid C is applied it bears against the band or
ring and is held air tight. The lid C is preferably dished or formed with a groove
or recess e around its edge whereinto the packing strip may be conveniently slipped
and so that when fitted over the box, the lid bears on the packing band or ring
which may be inside or outside the box, whilst the outer turned over edge or flange
of the lid being pressed hard against the outside of the box or against the packing
by machine or by hand.
In boxes in which the recess or groove is formed in the edges of the box to
receive a single flange or turned over edge on the lid, the ring or band of rubber
or other packing material may be fitted on the lid instead of on the box. In cases
17

page_text: in which the recess or groove is made both in the lid and in the body of the box a
ring or band of packing material, may be applied to both.
The box may be made round, square, oblong or of other shape and a bend may
be formed around the sides of the box in:proximity to the lid to facilitate pressing
open of the turned over edge by the use of a knife or like instrument.
Having now, particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is ;-
In a biscuit tin or other box the provision of a packing ring or strip-secured by
pressure between the box. and the lid substantially as described.
