COMPLETE SPECIFICATION.
Improvements in Bottles, to Prevent them being Refilled.
We, WALTER ERNEST HALL, Dentist, WILLIAM EDWARD WOODS, Chemist,
and GEORGE WILLIAM SHAILER, Settler, all of 54 Lambton Quay, Wellington,
in the Colony of New Zealand, 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 our invention is to provide a bottle which cannot be refilled after
its original contents have been extracted.
It is well known that fraud is practised to a considerable extent with bottles at.
present in use, as they are refilled with an inferior liquid which is passed off as
genuine and corresponding with the old brand left upon the bottle. Our invention
prevents such frauds in a simple and inexpensive manner.
We carry the object of our invention into effect by moulding the bottle with a
neck, having its lower part of greater diameter than the upper, and into this lower
part we introduce a washer preferably of cork. Into the interior of this cork
washer is forced a stopper having corrugations to grip into the cork, and into the
interior of the cork, which is hollow, is fixed a cork washer which acts as a valve
seat to a ball valve. Liquid when being poured from the bottle will pass through
the inner cork washer, lift the ball valve and pass out by orifices provided for the
purpose, and thence into the neck of the bottle by the annular orifice left around
the stopper. An ordinary cork is used for sealing the bottle.
The orifices in the stopper are arranged at such a height above the ball valve as
to exclude the possibility of a small instrument being introduced and the ball
tampered with, and should an attempt be made to withdraw the stopper, the outer
cork washer would be withdrawn also, but would be stopped when it reached the
narrower part of the neck.
In order that our invention may be most easily understood by one skilled in the
art to which it appertains, we will now proceed to describe the same in detail,.
reference being had to the accompanying drawings.
Figure 1 is a sectional elevation of our bottle with the stopper in position.
Figure 2 is a section of the stopper.
Referring to the views, the bottle (a) has a neck (b) with its lower part of
greater diameter than the upper, and provided with a cork washer () which is
prevented from falling into the bottle by shoulder (a'). The stopper (c) is forced
into washer (b) and grips the same by its corrugations (c). Into the interior of
the stopper we introduce a ball valve (d) made preferably of hollow vulcanite, so
that it will just float in water, and the cork washer (d) acts as a valve seat for
valve (d). Liquid when being poured from the bottle will pass through
washer (d), past valve (d), through orifices (c 2) and thence to the neck of the
bottle through annular orifice (c 3). The upper surface of the stopper is grooved
to prevent a sucker being applied thereto to withdraw the same.
An ordinary cork (f) is employed for sealing the bottle after the stopper has
been fixed in position.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is,
.
1. In a bottle, a neck having its lower part of larger diameter than the upper to

page_text: receive a washer into which a stopper is forced and gripped by corrugations said
stopper being provided with a ball valve and orifice for passage of the liquid, and
having its upper part of a diameter slightly less than the narrow part of the neck,
all substantially as and for the purposes set forth herein.
2. In a bottle in combination, a neck having its lower part of increased diameter,
a cork washer fitting the same, a stopper having its lower part corrugated and a
corrugated top of a diameter slightly less than the narrow part of the neck,
substantially as and for the purposes set forth herein.
3. A bottle constructed arranged and operating substantially as and for the
purposes set forth herein and illustrated by the accompanying drawing.
Dated this 28th day of September 1896.
