PROVISIONAL SPECIFICATION.
Improvements in and connected with Non-refillable Bottles and like
Vessels.
I, EDWARDS ATKINSON, of 12, Spencer Mansions, West Kensington, in the
County of London, Gentleman, do hereby declare the nature of this invention
to be as follows;-
This invention relates to improvements in and connected with non-refillable
bottles and like vessels of the kind described in the Specification of Application
No. 2974 of 1897.
According to the present invention I employ a bottle or vessel the neck of which
is constructed in a similar manner to that described in the. said former specifi-
cation and provided with a perforated screw plug irremovably fixed therein but
in lieu of forming the underside of the fixed plug with a recess, I form it with
a hemispherical boss or projection.
Between the hemispherical projection and the valve seat I provide a hemis-
pherical plug designed to fit on to the valve seat, its upper side being formed
with a conical or taper recess, that is to say, a recess the diameter of which
gradually diminishes inwardly and which is designed to fit over the hemis-
pherical projection upon the underside of the plug.
The plug, which may be made of glass,, porcelain or other suitable material
and in one or two parts, is provided with one or more longitudinal peripheral
grooves along its lower part, the said groove or grooves at its or their upper
ends being continuous with one or more radial grooves which extend to the
central or eccentrically formed perforation of the plug which forms the outlet
for the liquid, the said outlet being normally closed by a cork.
With this device for stoppering and preventing bottles being refilled before it
is tilted to the horizontal, the cup shaped valve slides on the hemispherical pro-
jection from its seat, thereby allowing the contents of the bottle to flow through
the valve and through the peripheral grooves cut in the stopper and so to the
central outlet or mouth of the bottle.
In some cases where I make the plug in two parts I form the upper perforated
part with a projection on its underside which fits into a recess in the lower part
into which the peripheral grooves open so that when the bottle is sufficiently
tilted the contents flow through the valve and the peripheral grooves into the
recess in the lower part of the plug and thence escape through the perforated
upper part of the plug.

I, EDWARDS ATKINSON, of 12, Spencer Mansions, West Kensington, in the
County of Loudon, Gentleman, 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 relates to improvements in non-refillablo bottles and like
vessels.
According to the invention I employ a bottle or vessel the neck of which
is formed with an internal valve seat as hereinafter described and is provided
with a perforated screw plug irremovably fixed therein and having on its under-
sido a hemispherical boss or projection.
Between the hemispherical projection and the valve-seat I provide a hemi-
apherical valve designed to fit on to the valve-scat, its upper side being formed
with a conical or taper recess, that is to say, a recess the diameter of which
gradually diminishes inwardly and which is designed to fit against the hemis-
pherical projection upon the underside of the plug.
The plug, which may be made of glass, porcelain or other suitable material
and in two parts, is provided with one dr more longitudinal peripheral
grooves along its lower part, the said groove or grooves at its or their upper
ends being continuous with one or more radial grooves which extend to a
central or eccentrically formed perforation of the plug which forms the outlet
for the liquid, the said outlet being normally closed by a cork.
With this device for stoppering and preventing bottles being refilled, as soon as
the bottle is tilted to a suitable angle below the horizontal the cup shaped valve
slides on the hemispherical projection from its seat, thereby allowing the con-
tents of the bottle to flow through the valve and through the peripheral grooves
out in the stopper and so to the central or eccentric outlet or mouth of the bottle.
In the accompanying drawings,
Figure 1 is a vertical section through a bottle provided with a stopper made
according to the invention
Figure 2 is a partial vertical section of the bottle without the stopper.
Figure 3 is an elevation; and,
Figure 4 a plan of the upper part of the perforated screw plug:
Figure 5 is a plan; and,
Figure 6 an elevation of the lower part or disc portion of the plug:
Figure 7 is a plan of the valve; and,
Figure 8 an elevation thereof:
Figures 9, 10 and 11 are respectively two sections and an elevation shewing
the position of the valve when the bottle is held at different inclinations.
a is the bottle the neck b of which is formed with an internal valve scat c and
with a ledge or support d for the purpose hereinafter described.
e is a valve, the said valve being hemispherical in shape and being formed at
its upper side with an internal conical or taper recess of that is to say, a recess
the diameter of which gradually diminishes inwardly and with a cylindrical ex-
tension g upon its underside, the said extension serving to weight the valve;
his the upper part of the screw plug with which the mouth of the bottle is pro- 4
vided, the said plug being formed with a central hole i designed to be normally
closed with a cork in the usual manner. is the lower or disc part of the
plug, the said disc being provided with an external rim upon its upper end

page_text: !B
whereby the said disc can be held upon the above mentioned ledge d in the
neck of the bottle 7 is the hemispherical boss upon the lower portion k of
the plug, the said boss being of such a size that the hemisphorical valve can fit
against or over it as hereinafter described. m, m are longitudinal peripheral
grooves formed in the said lower part of the plug, and n, n are the radial grooves
which are continuous with the said longitudinal grooves and which radial
grooves n extend into a central recess of the said disc which recess o
directly underneath the central holo i in the upper part of the screw plug.
With this device for stoppering and preventing bottles being refilled, it will
be obvious that, when the bottle is in its upright position, the valve e rests upon
its seat c as shewn in Figure 1. As the bottle is gradually tilted the valve e slides
on its seat without, however, leaving it, as shewn in Figures 9 and 10, and will
do so until the bottle is inclined considerably below the horizontal, as illustrated
in Figure 11, when the valve drops on to the hemispherical boss and the con-
tents of the bottle can then flow freely through the said valve and thence through
the grooves m and n into the recess and through the hole i out of the bottle.
From the above described arrangement and operation it will be obvious that
as the valve will return to its seat before the bottle is rotilted to the horizontal
position the bottle cannot be refilled after being emptied, without removing the
screw plug and valve
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:
The combination with a bottle of a device for closing and preventing the re-
filling of the bottle, the said device comprising a screw plug having a central
hole closed by a cork, a disc supported in the neck of the bottle below the plug
and having longitudinal peripheral and radial grooves and a hemispherical pro-
jection or boss upon its underside, and a weighted hemispherical valve designed
to rest upon a valve seat formed in the bottle neck and having a conical or
taper recess arranged to fit against the hemispherical boss, substantially as, and
for the purpose, hereinbefore described and illustrated in the accompanying
drawings.
