Improvements in Cans, Jars, Bottles, and other similar Vessels.
1, WILLIAM DE NORMANVILLE, of Leamington, in the County of Warwick, Civil
Engineer, do hereby declare the nature of this Invention to be as follows :—-
The object of my invention is to facilitate the pouring of liquids, from cans, jars,
bottles, and other similar vessels having narrow necks or openings. In such vessels
there being only a small orifice through which the liquid can leave the vessel, and
through which, at the same time, the air must enter to replace the liquid, a difficulty
is experienced in quickly emptying the vessel, and obtaining a full and steady flow of
liquid. The stream is generally more or less intermittent, causing splashing and a loss
of liquid, especially when it is attempted to pour into another vessel having a small
opening.
According to my invention, I provide an air duct either formed within the thickness
of the material of which the vessel is made, or affixed to the vessel after, or during its
construction.
This duct communicates at one end with the interior of the vessel, while the other
end is open to the atmosphere, within or near the neck of the vessel. When liquid is
poured from the vessel, the latter is held with the air duct uppermost, and the said
duct, ending high up in the body of the vessel, affords a free passage for the air, so
that the liquid can flow from the vessel in a full, steady, and uninterrupted stream.
The end of the duct open to the atmosphere, may be arranged to be closed by the
same device which closes the neck of the vessel, or may be provided with an
independent device for this purpose.
As the body of contained air in the vessel will shift from near the neck end to the
lower end, as the tilting of the vessel continues in pouring, I may provide one or
more additional air ducts, the additional ones terminating nearer to the bottom than
the first, in order to ensure a free ingross of air, in all positions of the vessel, and I
may also provide two or more air ducts on different sides of the vessel, so that it need
not be held with one special side uppermost in pouring.
Dated this 1st day of August 1889.

COMPLETE SPECIFICATION.
Improvements in Cans, Jars, Bottles, and other similar Vessels.
I, WILLIAM DE NORMANVILLE, of Leamington, in the County of Warwick, Civil
Engineer 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 :-
The object of my invention is to facilitate the pouring of liquids from cans, jars,
bottles, and other similar vessels, having narrow necks or openings. In such vessels
there being only a small orifice through which the liquid can leave the vessel, and
through which at the same time, the air must enter to replace the liquid, a difficulty
is experienced in quickly emptying the vessel and obtaining a full and steady flow of
liquid. The stream is generally more or less intermittent, causing splashing and a
loss of liquid, especially when it is attempted to pour into another vessel having a
small opening.
According to my invention I provide an air duct, either formed within the thickness

of the material of which the vessel is made, or affixed to the vessel, after or during its
construction. This duct communicates at one end with the interior of the vessel,
while the other end is open to the atmosphere within or near the neck of the
vessel.

In the accompanying sheet of drawings, Fig. 1 is an elevation, partly in section,
and Fig. 2 a cross section through the line in Fig. 1 of an ordinary beer or wine
bottle, shewing my invention applied thereto; Fig. 3 is a similar view of an
earthenware jar, and Fig. 4 a similar view of a metal can.
Similar letters of reference denote similar parts throughout the drawings.
Referring to Figs. 1 and 2, A is an air duct formed within the thickness of the neck
of the bottle, or affixed thereto, one end opening into the interior at B, near the
junction of the neck with the cylindrical part of the bottle, and the other end opening
within the neck, or mouth of the bottle, at C.
When liquid is poured from the bottle it is held with the air duct A uppermost, and
as the said duct ends high up in the body of the vessel at B, it affords a free passage
for the entrance of air, so that the liquid can flow from the bottle in a full, steady, and
uninterrupted stream.
ני
In Figs. 3 and 4, similar air ducts A are shewn. The duct being formed in the
thickness of the material in the earthenware jar, Fig. 3; and consisting of a tube,
fixed within or without the can, in Fig. 4. In all the examples shown, the upper
end C of the duct is so arranged that it opens within the mouth of the vessel, and is
therefore closed by the stopper, cork, or other device which closes the mouth of the
vessel. The duct being held uppermost, the effect of gravity, combined with what is
known in hydraulics as "
contraction, causes the stream of liquid not to maintain
contact with the upper side of the mouth, even when flowing freely, and a clear
entrance for air is therefore obtainable, though the orifice is within the mouth of the
vessel. As the body of contained air in the vessel will shift from near the neck end
to the lower end, as tho tilting of the vessel continues in pouring, I may provide one
or more additional air ducts, the additional duct or ducts terminating nearer to the
bottom than the first duct, or close to the bottom, in order to insure a free ingress
of air in all positions of the vessel.
In the examples shewn in the drawings, such an additional duct is indicated by the
dotted lines D, which represent a duct or tube, opening into the bottom of the vessel
at E, with an orifice in the neck or mouth as before described, I may also as a further
modification provide two or more air ducts on different sides of the vessel, so that it
need not be held with one special side uppermost in pouring.
I wish it to be understood, that 1 make no broad claim to the use per se of a
separate inlet for air to facilitate pouring liquid from a vessel, as such separate inlet is,
under certain forms, an old and well known device, as for example the ordinary
"dropping or "washing" bottle for laboratory use, but 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 :-
"
1. In a bottle, jar, can, or other similar vessel, a duct A, formed within the material
of which the vessel is comprised, or affixed thereto, and communicating with the
interior of the vessel at B, and with the mouth at C, and closed by the same device as
. the said mouth, for the purpose substantially as herein set forth.
.
2. In a bottle, jar, can, or other similar vessel, one or more additional ducts D,
formed within the material of the vessel, or affixed thereto, and communicating with
the interior of the vessel at E, and with the mouth, and closed by the same device as
the said mouth, for the purposes substantially as herein set forth.
3. The combination, in a bottle, jar, can, or other similar vessel, of two or more
ducts, as set forth in the preceding claims, on different sides of the vessel, for the
purposes substantially as herein set forth.
4. A bottle, constructed substantially as herein described and shewn, with reference
to Figs. 1 and 2 of the accompanying drawings.

page_text: 5. A jar, constructed substantially as herein described and shewn, with reference to
Fig. 3 of the accompanying drawings.
6. A can, constructed substantially as herein described and shewn, with reference
to Fig. 4 of the accompanying drawings.
