An Improved Non-Refillable Bottle.
I, CHARLES JOSEPH COOZE, of Carterton, in the Provincial District of Wellington,
in the Colony of New Zealand, Carriage Trimmer, 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 this invention is to provide a cheap and simple bottle which cannot
be refilled after its original contents have been poured out.
To this end I fit a glass disc into the neck of the bottle and provide the disc with
a trap formed by bending a piece of tubing into a U shape, or by making a bowl with
a partition, so that liquid may flow into the tube or bowl to the other side of the disc.
A tube of small diameter extends above the neck and downwards through the said
disc to the bottom of the bottle, and immediately above the disc it is weakened by

attenuation so that it may be readily broken off.
broken off a perforated disc is fitted into the neck of the bottle above the first
mentioned disc.
The accompanying drawing illustrates the invention.
Figure 1 is a section of a bottle fitted with my improvements as they appear after
the bottle has been filled.
:
Figure 2 is a section of the neck shewing the parts as they appear before the bottle
has been filled.
Figure 3 is a section on the line A-A, Figure 1.
Figure 4 is a section on the line B-B Figure 1.
Figure 5 is a section of the trap when made as a bowl.
Figure 6 is a plan of the same.
Figure 7 shews an alternative position for the disc.
Similar figures of reference indicate corresponding parts where they occur in the
several views.
(1) is the body of the bottle, (2) the neck, (3) a glass disc cemented in the neck,
(4) a trap made by bending a piece of glass tubing to the shape shewn, (5) is a tube
of small diameter shewn in Figure 2, extending above the neck of the bottle and
weakened at the part (6) so that it may be readily broken off as shewn in Figure 1,
(7) is a perforated disc cemented in the neck. Shoulders (3) and (7b) are made in
the neck to form a seat whereon the discs (3) and (7) respectively may be cemented.
The bottle is filled by attaching an india rubber tubing (9) upon the tube (5) as
shewn on Figure 2, which tube is connected to an air pump or a vessel exhausted of
air. The bottle is then inverted so that the neck is down most, and in this position
the mouth of the neck is immersed in a quantity of the liquid with which it is desired to
fill the bottle.
The air is exhausted from the body (1) of the bottle and is replaced by the liquid
until the bottle is full. The neck is then lifted out of the liquid, the bottle turned
with its neck uppermost, the india rubber tube (9) removed, the glass tube (5) broken
off at the part (6), the disc (7) cemented in position, and the cork (10) inserted in
any ordinary manner as shewn by Figure 1.
The liquid may be poured out after the cork has been drawn and the cork tilted in the
ordinary way, since the liquid will pass out through the trap (4) and air will enter

page_text: through the broken tube (5); but it is impossible to refill the bottle, and an attempt
to do so would choke the trap and tube (5) with liquid and prevent the air contained
in the bottle from escaping.
Figure 7 shews the disc and the attenuation (6) in the same plane. With this
form the perforated disc (7) may be fixed before the bottle is filled, and the tube
broken off afterwards as previously described.
The perforated disc (7) is for the purpose of preventing tampering with the tube (5)
or the trap (4), and as a further precaution against tampering the rims of the
trap (4) have serrations (4*).
The inner end of the trap (4) is sloped as shewn so that the liquid may freely pass
out whilst the tip (11) is kept close to the disc (3).
On Figures 5 & 6 the trap (12) has a bowl (13) and partition (14) attached to or
integral with disc (3) and with an inlet (15) and cutlet (16) for the liquid.
I prefer to bend the tube (5) to carry its lower end (17) near to the side and at the
bottom of the bottle as shewn on Figure 1, as by this arrangement the tilting of the
bottle is reduced as much as possible to make the liquid flow through the trap, for
the bottle must be tilted far enough to bring the surface of the liquid below the lower
end of the tube (5).
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination in a non-refillable bottle having the upper part of its neck
enlarged to form a shoulder of a disc secured within the neck, a trap upon the disc,
a tube extending above the mouth of the neck and to the bottom of the bottle, sub-
stantially as set forth herein,
2. The combination in a non refillable bottle having the upper part of its neck
enlarged to form shoulders, of a disc secured within the neck, a trap having serrated
rims upon the disc, a tube passing through the disc and extending to the bottom of
the bottle, and a perforated disc secured in the neck above the first disc, substantially
as set forth.
3. In devices adapted to be inserted into a bottle neck, the combination of a disc
carrying a trap consisting of a piece of tubing bent into a U shape and having an
inlet beneath the disc and an outlet above the disc, and a tube passing through the
disc and extending to the bottom of the bottle, and an attenuated part in the said tube
to facilitate breaking at that part, substantially as set forth.
4. The improved non refillable bottle consisting of parts constructed, arranged,
combined, and operating, substantially as and for the purposes set forth herein and
illustrated in the accompanying drawing.
