PROVISIONAL SPECIFICATION.
Improvements in Cases, Chests, and Packages, and in the Method of
Making same.
I, EDWARD BRICE KILLEN of Cherryvale, Belfast, County Down, Tea Buyer,
do hereby declare the nature of this invention to be as follows:-
Whereas cases, chests and packages as now usually made have several objections
amongst others that of taking up great space with consequent expensive freightage
when sent out empty and ready made up, and if sent out in parts difficulty is often
found in putting them together air-tight with the available appliances.
This invention has for its object to overcome these objections by constructing
air-tight packing cases which, when transported empty, can be unfolded and packed
in small space.
To effect this I take a sheet of metal or other material and bend it to the
form of a square tube with open ends, the edges being turned back so as to
interlock with each other; between the interlocking edges runs a piece of felt
or other suitable material making an air-tight seam when the case is screwed or
otherwise closed up.
The end joints are formed in the following manner :-Two frames exactly fitting
the end of the case not only keep the sides of the case extended but on these
two frames is attached the felt or other suitable material which runs round
them, and, on the two frames being inserted into the package, the felt is between
the inserted frame and the sides of the package and overlaps the ends of the
package on the outside. The ends are formed with a rim fitting round the case
and are drawn tightly together by means of suitable screw or screws passing
through both ends compressing the felt placed in with the frame thus forming an
air-tight case.

COMPLETE SPECIFICATION.
Improvements in Cases, Chests, and Packages, and in the Method of
Making same.
I, EDWARD BRICE KILLEN of Cherryvale, Belfast, County Down, Tea Buyer,
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:
Whereas cases, chests and packages as now usually made have several
objections amongst others that of taking up great space with consequent expen-
sive freightage when sent out empty and ready made up, and if sent out in
parts difficulty is often found in putting them together air-tight with the available
appliances.
This invention has for its object to overcome these objections by constructing
air-tight packing cases which, when transported empty, can be unfolded and packed
in small space.
And in order that my said invention may be properly understood, I have here-
unto appended an explanatory sheet of drawings, whereon
Fig. 1 is a side view of the packing case.

page_text: Figs. 4 and 5 are enlarged detail views.
Fig. 6 shows a modification.
Referring to the drawings:-
In carrying out my invention I use a sheet of metal A or equivalent suitable
material and bend it into the form of a square tube, with the corners rounded off,
as shown at Fig. 2, and with open ends. The edges a, b, of the metal sheet are
turned back or doubled as shown more particularly at Fig. 4 so that they can be
easily locked together. Between the interlocked edges a, b, is inserted a strip or
piece of felt c or other suitable material for the purpose of making an air-tight
joint when the case is screwed up.
The top d and bottom e of the case or package are both made like lids with
inwardly projecting rims f. The rims f fit into the ends of the case and the space
between said rims and the metal sheet A, is filled with a strip of felt g (see Figs. 4
and 5) so as to make the joint air-tight.
The top and bottom may be struck-up to the required form or be made of sheet
metal with a rim fitted thereto or be cast.
When the ends are fitted in place they preserve the shape of the case.
The bottom inay be secured by one or more small bolts k, k¹ to the sheet A. The
bolt k also serves to hold the joint a, b, tight.
The ends are drawn together by means of one or inore screws or bolts h. In Figs. 1
to 3, four bolts one at each corner are shown and in Fig. 6 only one central bolt is
used. The bolts or screws may or may not as desired be counter-sunk at their
lower ends.
A felt or other washer may be placed between the nuts or heads of the bolts and
the ends of the case.
When it is desired to send the package abroad empty the bolts are unscrewed,
the ends taken off and the sheet metal body A spread out flat. Great saving in space
is thereby obtained and freightage is consequently reduced.
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 :-
A case or package, capable of being unfolded and packed into a small space and
which, when put together, is air-tight or nearly so, constructed substantially as
herein before described with reference to Figs. 1 to 5 and to the modification at
Fig. 6 of the drawings annexed.
