I, HENRY COGAN, of Preston, near Yeovil, in the County of Somerset, Yeoman, do
hereby declare the nature of this invention to be as follows:-
This invention has reference to a construction of cans and similar vessels suitable
for containing volatile or other liquids and stoppers therefor such that liquid may be
withdrawn without removal of the stoppers.
To this end the vessel is formed or provided with a passage to receive a plug
stopper able to be turned in such passage. From the said passage there are others
leading respectively to the interior of the vessel and to the external air. The plug
stopper is so formed with passages that in one position the exit orifice for liquid as
also the air passages will be closed, whereas in another position of the plug stopper the
exit passago for liquid will be open and communication between the external air and
the interior of the vessel will be established by the air passages thus enabling liquid to
bo freely poured out of the vessel without removal of the plug stopper.

page_text: Improvements in Cans and similar vessels and Stoppers therefor
I, HENRY COGAN, of Preston, near Yeovil in the County of Somerset, Yeoman, 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 has reference to a construction of cans and similar vessels suitable
for containing volatile or other liquids and stoppers therefor such that liquid may be
withdrawn without removal of the stoppers.
To this end the vessel is formed or provided with a passage to receive a plug
-stopper able to be turned-in such passage.
From the said passage there are others leading respectively to the interior of the
vessel and to the external air. The plug stopper is so formed with passages that in
one position the exit orifice for liquid as also the air passages will be closed whereas
in another position of the plug stopper the exit passage for liquid will be open and
communication between the external air and the interior of the vessel will he
established by the air passages thus enabling liquid to be freely poured out of the
vessel without removal of the plug stopper.
The said can or vessel and plug stopper may be made of various materials according
to the nature of the liquid to be contained and poured out and according to the usage
to which the vessel will be subjected thus for non-volatile oils, a sheet metal can with
wooden stopper may be used while for volatile or corrosive fluids more enduring and
exactly fitted constructions may be employed.
In the accompanying drawing is shown in section the upper part of a can con-
structed according to this invention. In Fig. 1. the plug or stopper is shown in
position for pouring out the contained liquid and in Fig. 2. the plug is shown turned
so as to close the passages.
a is the body of the can; a¹ its neck; a² a lining or bushing of suitable material
such as cork or wood usually provided in cases where (as in the illustration) the
vessel is of sheet metal. a plug or stopper with handle C₂ da passage in the plug
for liquid. e a passage through the can neck (and bush) for liquid. a spout
connected to the passage e. g a passage in the plug for air. ha passage in the can
neck for air. an opening from the passage
to the external air. 7 an air tube
connecting the passage h with the body of the can.
When the can containing liquid and having the plug in the position shewn in
Fig. 1. is tilted from the vertical attitude sufficiently to pour out liquid such liquid
will flow directly through the passages or conduits d and e to the spout whilst air
will flow into the opening k and from it through the passages or conduits h g and
to the interior of the can or vessel and will prevent the formation therein of a partial
vacuum such as would otherwise result and obstruct the outflow of liquid.
In the closed position of the plug shown in Fig. 2 both the liquid and air passages
are shut.

page_text: In the construction shown the air opening & communicates with the spout so that
if by accident or improper handling any portion of liquid should get into the air
tube, such portion would run out through the spout without being spilled or wasted;
but this construction is optional.
The air opening might be simply alongside of the spout ; or it might if more
convenient be formed directly from the passage g through the handle e to the external
air; or in any other suitable way.
C
Also the spout might be formed by a fold or groove in the neck; or the air tube /
might be formed to pass through the handle, or by a tube contained inside the vessel;
and the details might otherwise be varied.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, I declare that what I claim is :—
1. A can or similar vessel provided with a plug or stopper able to be turned in the
neck of such can or vessel, and with passages so arranged that in one position of the
plug or stopper there will be open conduits for the exit of liquid from the can or
vessel and for ingress of air to replace the liquid poured out; and in another position
of the plug or stopper the said conduits will be closed so as to prevent entrance of air
and loss of liquid by spilling or evaporation substantially as described.
2. The construction and arrangement of parts shewn in the drawings and described
with reference thereto.
