Improvements in Cans or Receptacles for Printing-ink, Paste, Glue
and other Substances.
I, JOHN EBENEZER BOUSFIELD, of the firm of G. F. Redfern & Co., the
General Patent Office, No. 4, South Street, Finsbury, in the County of London,
Patent Agents, do hereby declare the nature of this invention (a communication
to me by William H. Golding of Forthill Square, Boston, Massachusetts, in
the United States of America) and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement :-
This invention relates to cans or receptacles more especially designed for holding
printer's ink, paste or glue, and it has for its object to provide simple means for
preventing the evaporation and the formation of skin on the contents of the can.
In carrying out the invention I provide the can with an interior sliding cover or
lid, made tapering at the centre so as to allow for the ready escape of the air, the
said cover having at its apex a removable cork or plug. I also preferably provide
the cover with a handle or bail to facilitate the removal of the same when
desired.
In the accompanying drawing
Figure is a vertical central section of a can or receptacle embodying my
invention.
Figure 2 is a top plan of the same with the outer cover broken away.
Like letters of reference indicate like parts in both views.
A designates the can or receptacle proper which may be of any suitable
construction and capacity; B is the usual removable cover having a downwardly
projecting flange to embrace the upper edge of the can, and bearing upon an
annular bead a on the can.
C is the sliding cover or lid provided with an annular flange which is made
to fit the interior of the can as seen in Figure 1, the said cover being conical or
tapered toward its centre where it is provided with an opening surrounded by a
vertical flange c.
Dis the removable plug or cork (or a screw-cap may be employed) for closing the
opening in the cover C.
E is the bail or handle preferably of wire hinged in any suitable manner, such
as at d, to the top of the cover C so that it can be turned up into a vertical position
when it is desired to lift the sliding lid out of the can. It normally lies flat upon
the upper face of the lid as seen in Figures 1 and 2.
In practice this lid is arranged as shown in the drawing with the cork or plug in
place, and serves to prevent evaporation of the ink or formation of skin thereon.
When large quantities of the ink are desired, the lid may be removed and the ink
poured out or otherwise removed. When only a small quantity is desired at a
time, the cork or plug D is removed and pressure applied upon the lid, when the
contents will be forced out of the hole at the centre. The taper of the lid from
the periphery toward the central opening allows of the ready escape of the
confined air.
The depending flange d of the sliding lid is important; it serves to keep the
lid from tilting and insures its moving in a direct line with the walls of the can;
its lower edge can be bevelled or sharpened as shown in Figure 1 to facilitate
the removal of the ink adhering to the walls of the can as the lid is forced
down.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
(1.) The improved can consisting of a receptacle provided with a removable cover,
and an interior sliding cover having a downwardly projecting surrounding flange
bevelled on its edge, the said sliding cover being tapered from the top of the flange
toward the centre of the cover and terminating in a vertical flange surrounding a
central opening, having a removable stopper embraced by the said vertical flange,
substantially as hereinbefore described and shown and for the purpose specified.
(2.) The combination with a can or receptacle provided with a cover, of an interior
conical sliding lid having a downwardly projecting surrounding flange, a central
opening closed by a removable stopper, and a handle, substantially as hereinbefore
described and illustrated in the accompanying drawing.
