Improved Stoppering and Pouring Device for Bottles and the like.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 322, High Holborn, in the County of Middlesex, 6, Lord Street,
Liverpool, and 6, Bank Street, Manchester, both in the County of Lancaster, and
Lower Temple Street, Birmingham, in the County of Warwick, Civil Engineer,
do hereby declare the nature of my invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
The present application has for its object a novel pouring stopper adapted
especially for viscous liquids. With the ordinary pouring stoppers in use the
exit of such a liquid is difficult by reason of its nature, and does not readily admit
of the access of air into the bottle through the same orifice.
In order to obviate this drawback I have devised a method for providing the
stopper with a special tube designed entirely to admit air to the interior of the
bottle; this tube is closed when the bottle is not in use by means of a plug carried
by the cover which prevents at the same time the escape of the liquid.
The accompanying drawing illustrates my improved stopper in vertical section,
Figure 1, with the orifice closed, and in vertical section in Figure 2 with the orifice
open.
Figure 3 shows a vertical section of a modification of my device.
Figs. 4 and 5 shew a modification.
The drawing is on a magnified scale.
The exit tube a of the liquid which passes from the stopper b is compressed at c
above which is the screw d which it bears at its upper part in order to hold the
cover e when the exit opening for the liquid is uncovered. The return tube for
the air placed beside the exit tube reaches to the upper part of the disc g forming
one piece with the central tube a; this tube f is slightly expanded at its upper
end in order to form a good joint with the bottom of the cover e without projecting
above the disc g. The screw cover e has at its lower end a second disc h provided
with a washer i which serves to cover and close the orifice of the tube f. A con-
traction is effected at in the cover e in order to retain the latter against the
piece c when it is at the upper part of its course. The exit tube a being then
unclosed.
It will be obvious that in order to close the bottle it is sufficient to screw down
the cover e which has the double result of pressing the stopper k upon the upper
orifice of the tube a, and at the same time the washer upon the disc g and con-
sequently of preventing access of air to the interior of the bottle. The opposite
motion of the cover e results in unclosing the two orifices simultaneously.
Figure 3 shows in vertical section a modification of this arrangement in which
the side tube f for the entrance of air is replaced by a channel o formed in the

page_text: same piece of metal as the channel a for the exit of the liquid. The cover is
identical in construction to that already described.
Figures 4 and 5 represent a third modification of my invention arranged for the
purpose of effecting economy in the manufacture. The tuber for the passage of
the air is placed inside the conduit a for the escape of the liquid. The two conduits
consequently have their upper orifice upon the same plane surfaces and a single
elastic ring t placed in the screw cover m closes at the same time both orifices.
It will be noticed that in this arrangement and contrary to those already described
the screw cover m must be removed completely in order to admit of the liquid
being poured out, as is shown in Figure 4. In Figure 5 on the other hand the said
cover is represented in place and closing at the same time the air entrance tube r
and the exit tube a for the liquid.
It is obvious that in this arrangement as in the foregoing one the entrance tube
for the air may be made in one piece with the main body of the apparatus
containing the conduit a for the liquid, or it may be formed of a tube of metal
or the like added to and secured in the said conduit a.
The same system of pouring stopper may be applied to bottles of all sizes even
to very small ones; it may also be applied to bottles with ball stoppers employed
for pouring out liquors. The ball sometimes sticks against the mechanism and it
is necessary to shake the bottle in order to allow the liquid to escape.
My pouring stopper with air tube obviates this drawback.
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. The application to pouring stoppers of a special tube for the admission of air
in order to facilitate the flow of the liquid.
2. The use and arrangement of the closing cover which closes or opens simul-
taneously both the tube for the flow of the liquid and the tube for the entrance
of the air.
3. The application of my pouring stopper substantially as set forth in Claims 1
and 2 to every suitable application.
