I GEORGE HENRY WILLIAMSON of the firm of W. B. Williamson and Sons of
Providence Works in the City of Worcester Manufacturers do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN METALLIC BOXES OR CASES
FOR STORING ARTICLES OF FOOD TOBACCO SNUFF AND PAINT AND FOR OTHER
LIKE PURPOSES to be as follows :—
"
My invention consists in constructing the said boxes or cases in the manner
hereinafter described whereby the articles or materials stored in the said boxes or
cases are protected against the action of the air during storage and transit in
consequence of the boxes or cases being hermetically sealed when introduced into
commerce the said cases or boxes being provided with a close fitting cover which
protects the contents of the box or case after it has been opened.
I will describe my invention as applied to a cylindrical or nearly cylindrical
case made of tin plate. The hollow cylinder of tin plate is closed at bottom by a
disc the edge of which is turned over the bottom of the said cylinder and soldered
thereto.
The said disc constitutes the bottom of the box or case and has a central opening
at which the material to be stored in the box or case is introduced the said opening
being closed after the box or case has been filled by means of a disc soldered thereon.
The bottom disc may be without a hole in the centre in which case the packer
would fill the box and then solder the bottom disc on the outside edge in the
usual way.
The top of the box or case is made as follows:-The open top of the hollow
cylinder of tin plate is slightly contracted for a short distance so as to slightly
diminish the diameter of the box or case at top and leave a slight shoulder a short
distance (say one eighth of an inch) from the top A disc of the thin tin plate
commonly called tagger tin plate and of slightly larger diameter than the box or
case is operated upon by dies and pressure so as to form its extreme edge into the
figure in cross section of an inverted U or an inverted narrow trough. This disc of
tagger tin plate is placed upon the open top of the box or case its inverted trough

The top disc may be made of sheet lead or strong tin foil but tagger tin plate is
preferably used. Instead of being shaped as described the disc employed may
be flat.
A removeable lid or cover of the ordinary kind is fitted upon the top of the box

I GEORGE HENRY WILLIAMSON of the firm of W. B. Williamson and Sons of
Providence Works in the City of Worcester Manufacturers 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 :-
My invention consists in constructing the said boxes or cases in the manner
herein after described, whereby the articles or materials stored in the said boxes
or cases are protected against the action of the air during storage and transit in
consequence of the boxes or cases being hermetically sealed when introduced into
commerce, the said boxes or cases being provided with a close fitting cover which
protects the contents of the box or case after it has been opened.
I will describe my invention as applied to a cylindrical or nearly cylindrical
case made of tin plate. The hollow cylinder of tin plate is closed at bottom by
a disc the edge of which is turned over the bottom of the said cylinder and soldered
thereto. The said disc constitutes the bottom of the box or case and has a central
opening at which the material to be stored in the box or case is introduced, the said
opening being closed after the box or case has been filled by means of a disc soldered
thereon. The bottom disc may be without a hole in the centre in which case the
packer would fill the box and then solder the bottom disc on the outside edge in
the usual way.
The top of the box or case is made as follows:-The open top of the bollow
cylinder of tin plate is slightly contracted for a short distance so as to slightly
diminish the diameter of the box or case at top and leave a slight shoulder a short
distance (say one eighth of an inch) from the top. A disc of thin tin plate com-
monly called tagger tin plate and of slightly larger diameter than the box or case
is operated upon by dies and pressure so as to form its extreme edge into the figure
in cross section of an inverted U or an inverted narrow trough. This disc of tagger
tin plate is placed upon the open top of the box or case, its inverted trough shaped
edge fitting upon the contracted top of the case. The disc of tagger tin plate is
soldered to the top of the box or case.
The top disc may be made of sheet lead or strong tin foil but tagger tin plate is
preferably used. Instead of being shaped as described the disc employed may be flat.
A removable lid or cover of the ordinary kind is fitted upon the top of the box
or case and sent out with it.
In opening a box or case made according to my invention the removable cover is
taken off and the soldered top of tagger tin plate is cut away with a knife. The
contents of the box or case are now exposed and in order to close the box or case,
after removing any portion of its contents, the loose or removable cover is employed.
The essence of my invention consists in contracting the top edge of the body of
the box or case, covering the said top edge with a disc of tagger tin plate, sheet
lead strong tin foil or other like metal or alloy and covering the said disc with an
outside loose cover which may be used when the top disc has been cut away.
I will now proceed to describe with reference to the accompanying Drawings the
manner in which my invention is to be performed.
Figure 1 represents in section and Figure 2 in plan of upperside a cylindrical
metallic box or case inverted or bottom upwards ready for filling before the central

page_text: filling opening in the bottom of the box or case is closed; Figure 3 represents in
section and Figure 4 in plan of underside, the said box or case, bottom downwards,
after it has been hermetically closed by the soldering of a disc over the central
filling opening; the said Figure 3 also exhibits the removable close fitting cover
detached; Figure 5 represents in section the lower part of the box represented in
Figure 1 drawn to a larger scale and Figure 6 represents the removable close fitting
cover drawn to the same scale as Figure 5.
The same letters of reference indicate the same parts in the several Figures of
the drawings.
a, a is the box or case; b is the bottom of the same; c is the filling central
opening in the said bottom b and c is the disc which has been soldered over the
said opening c after the box or case has been filled d is the top of the box or case
made of thin or tagger tin plate the said top of the box consisting of a disc
troughed at its edge d³ (see Figure 5). The top of the body of the box or case is
slightly contracted so as to leave a shoulder e as best seen in Figure 5. The
troughed edge d³ of the disc d of tagger tin plate being placed upon the contracted
top of the box or case a the said disc d is soldered in its place as represented in
the drawing; f is the removable close fitting cover placed upon the top of the box
and sent out with it, the said cover f being used to protect the contents of the
box or case after it has been opened. Although I prefer to fit the top d to the box
or case a by means of the troughed edge d soldered as described to the contracted
top of the case yet I do not limit myself thereto. For example, the outer part of
the troughed edge d² may be omitted in which case the inner part of the said
trough is on a level with the top edge of the case and the two edges are soldered
together. Or the troughed edge may fit and be soldered within the contracted top
of the case instead of clipping it as represented and described. Like modifications
may be adopted in all cases where a troughed edge is described or represented.
The box or case is sent into commerce with the central opening c unclosed and
with the removable close fitting cover f placed upon the tagger tin plate top d.
After
In order to fill the box or case it is inverted as represented in Figure 1 and the
material to be stored in it is. introduced through the central opening c.
filling the box or case the central opening c is closed or covered by the soldered
disc and the box or case is now ready for storing or transit as represented in
Figures 3 and 4. In opening the box or case the removable cover fis taken off
and the soldered top d of tagger tin plate is cut out with a knife. The contents of
the box or case are now exposed and in order to reclose the top of the box or case
after removing any portion of its contents the loose or removable cover ƒ is employed.
Instead of using a bottom having a central opening in it at which the box or case
is filled the bottom may consist of a complete disc troughed at its edge, the said
bottom after the box or case has been filled being soldered in its place.
This arrangement of my invention is represented in section in Figures 7 and 8,
Figure 7 representing the box or case inverted ready for filling through the open
bottom g and Figure 8 representing the box or case after the bottom has been
closed by the soldering of the trough edged disc h to the bottom edge of the box or
case the box or case being represented in the said Figure 8 with its tagger tin plate
top uppermost. The tagger tin plate top d and the removable close fitting cover
f
are the same as in the arrangement first described.
Instead of using a disc or top of thin or tagger tin plate having a troughed edge
a flat disc may be employed so that a flush top case or box is formed.
This con-
struction of box or case is represented open at its bottom and inverted in Figure 9
and closed at bottom. and with its top uppermost in Figure 10; Figure 11 repre-
sents the thin or tagger tin plate top and portion of the box or case drawn to a
larger scale. The disc of tagger tin plate forming the top of the box or case is
marked d and has a rim d' at its edge for fitting it upon and soldering it to the
contracted top e of the box or case. The other parts are the same as the corre-
sponding parts hereinbefore described The flush tagger tin plate top & Figures 9,
10 and 11 is removed by cutting as before described.

page_text: In place of filling the box or case through the open bottom or partly closed
bottom of the box or case, the thin or tagger tin plate top may be furnished with
a central opening through which the box or case is filled the said central opening
being closed after filling the box or case by soldering a disc over the said central
opening.
A box or case made according to this modification, open for filling, is represented
in section in Figure 12 and plan of upper side in Figure 13; Figure 14 represents
in section and Figure 15 in plan the box or case after it has been filled and the
central opening in the tagger tin plate top closed by a disc soldered to the edge of
the said central opening. In this arrangement the body a of the box and the
bottom hare of the ordinary kind; k is the tagger tin plate top provided with a
central opening through which the box or case is filled. After the box or case
has been filled the central filling opening is closed by the disc m, Figures 12
and 13 soldered to the edge of the said opening. The top of the box is then fitted
with the removable cover fand is ready for storage or transit. In opening the box
the cover f is removed and the tagger tin plate top k is cut away with a knife as
hereinbefore described, the removable close fitting cover f being used to reclose the
box or case after removing any portion of its contents.
I do not limit myself to making the boxes or cases of any particular sectional
figure for example they may be made cylindrical, square or square with the angles
rounded, or elliptical or of other figure in cross section.
Figures 16 and 17 represent in section and Figure 18 in plan a square or oblong
box with rounded angles the tagger tin plate top being made according to the
arrangement shown in Figures 7 and 8 and Figures 19 and 20 represent in section
and Figure 21 in plan a box or case elliptical in cross section having a tagger tin
plate flush top according to the arrangement represented in Figures 9. 10 and 11.
Although I have described the top of the box or case as made of thin or tagger
tin plate yet it may be made of thin sheet lead or strong tin foil or other metal or
alloy which can easily be cut with a knife.
Having now. particularly described and ascertained the nature of my inven-
tion and the manner in which the same is to be performed I declare that I claim
as my invention of "Improvements in metallic boxes or cases for storing articles of
food, tobacco, snuff and paint and for other like purposes,"
"
First. Contracting the top edge of the body of the box or case and covering the
open top by soldering to the said contracted top edge a disc of thin or tagger tin
plate, sheet lead, strong tin foil or other metal or alloy which can easily be cut
with a knife, and covering the said disc or top with a loose or removable close
fitting cover which cover after the tagger tin plate top has been cut away for
opening the box or case is used for reclosing the said box or case, the box or case
being filled from the bottom substantially as herein before described and illustrated
in the accompanying Drawings.
Secondly. Contracting the top edge of the body of the box or case and partly
covering the open top with a ring of thin or tagger tin plate, sheet lead, strong tin
foil or other metal or alloy which can easily be cut with a knife, the opening in
the said top ring being closed after filling the box or case by soldering a disc to the
edge of the said opening and covering the closed top of the box or case with a loose
or removable close fitting cover for the purpose and substantially as herein before
described and illustrated in the accompanying Drawings.
