PROVISIONAL SPECIFICATION.
An Improved Method of Constructing Hermetically Sealed or other
Tins, which can be Readily Opened.
I, THOMAS GRACEY, of 85 Long Acre, London, Gentleman, do hereby
declare the nature of this invention to be as follows:-
My invention consists in an improved method of constructing hermetically
sealed or other tins which can be readily opened, and is described below.
I construct a box made of tin or any other suitable material having the neck
slightly smaller than the body in order that it may take two lids, each of which
has a slot. The inner lid, which is soldered on to the neck, is made of tagger tin.
The outer lid is made of any suitable material and fits over the neck and slightly
over the body.
In the neck of the box is a groove, extending all the way round, in which is
placed a wire fixed at one end in any suitable manner, and at the other end is a
loop which is drawn through the slot in both lids. When it is desired to open the
tin, it is only necessary to remove the outer lid and draw the wire out and thereby
cut through the tagger tin. In order that the wire may more readily cut through
the tagger tin lid, I make a V shaped slot in the tagger tin. The wire, however,
may be loose and have a loop at both ends, which loops are drawn through the slot
in both lids, and when it is required to open the tin, both ends of the wire may be
drawn in the opposite directions, and thereby cut through the tagger tin in opposite
directions. It is not absolutely necessary to bring the wire loop through a slot in
the outer lid, but it may be more convenient. My invention is applicable to any
shape of box.

An Improved Method of Constructing Hermetically Sealed or other
Tins, which can be Readily Opened.
I, THOMAS GRACEY, of 85 Long Acre, London, Gentleman, 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 consists of an improved method of constructing boxes of tin or
other suitable material so that such boxes can be hermetically sealed or fastened
when the contents are placed therein, and opened with ease and facility without
the use of knife or cutter other than the means provided in the construction of
the box,
The improved box made in accordance with this invention is made of sheet tin
or other suitable material, and may be of any convenient shape. The top or
mouth of the box where the lid usually fits is of a slightly smaller diameter than

page_text: the body of the tin, so that the lid when pressed into position rests on the shoulder
thereby provided.
In the neck of the box formed above the shoulder before referred to, is provided
a groove extending all the way round. In this groove is placed a wire provided at
each end with a loop or ring attachment, or alternatively one end of the wire may
be soldered or otherwise fixed in the groove and the other end provided with a
loop or ring attachment. This wire being placed in position in the groove, with
the ring or rings as the case may be hanging down outside the box, a lid of tagger
tin is then placed over the neck and over the groove, carrying the wire above
referred to. This lid is provided with a narrow slot to allow of the wire end and
loop hanging free. The tagger tin lid is then soldered or otherwise fastened so as
to hermetically seal the box. This being done, a further lid made of ordinary tin
or other suitable material is then placed over the lid of tagger tin, and the box is
ready to send out. This outside lid acts as a guard to prevent the lid of tagger tin
being damaged in transit.
In the accompanying drawings:-
Fig. 1. represents the upper portion of a circular tin box made in accordance
with this invention and provided with the looped wire A. resting in the groove B.
and soldered to the box at A¹.
Fig. 2. represents the same with the tagger tin cover C. placed in position over
the wire and groove, ready for soldering to the box, and shewing the small slot in
front to allow of the looped end of the wire hanging free.
Fig. 3. represents the same with the addition of the outside tin lid D. placed in
position over the tagger tin cover C.
These drawings represent the use of wire with only one loop, but if desired a
loop or ring may be attached at each end of the wire, when the soldering of one
end is rendered unnecessary. Also, instead of allowing the loop or ring or rings to
hang down they may be turned up and laid on the top of the tagger tin cover so
that they are protected by the outer lid during transit."
When it is desired to open the box, it is only necessary to remove the outside
lid, and by pulling the loop or loops out of the grooves, cut through the tagger tin
lid, which can then be removed and thrown away, the outside lid being used to
close the box again while the contents are being used.
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 :-
A box constructed so that it can be hermetically sealed and opened when desired
by means of a wire attachment, substantially as described and set forth in the
foregoing Specification and drawings.
