1, JOHN WILLIAM MCDOUGALL, of Napier, in the Colony of New Zealand,
Journalist, 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 an effective stopper and bottle whereby
liquids may be preserved and liquids under pressure liberated in such quantities as
desired and the remaining portion re-stoppered and preserved under pressure.
The object of this invention is carried into effect by making the neck of the bottle
with a screw thread to take a correspondingly screwed stopper. Near the bottom
of the neck of the bottle is provided a shoulder, and a ring preferably of rubber
rests upon this shoulder to form a valve seat, or the rubber ring may rest in a
recess grooved in the stopper. The stopper is pierced axially for nearly its whole
length but near the bottom, branch holes are inade, so that when the stopper is
unscrewed the liquid may pass through the valve seat, the brauch holes, and
thence through the centre of the stopper. With such a stopper the bottle may be
filled without removing the stopper entirely from the bottle. A band of rubber is
placed around the neck of the stopper to make a watertight joint at the top
between the stopper and neck of the bottle.
In a modification, the valve is held up to its work by a spring and a perforated
pusher is used to force back the valve against the pressure of the spring, and in the
case of liquids under pressure against such pressure also. The introduction of the
spring makes the stopper serviceable upon bottles which hold liquid not under
pressure. Inside the top of the pusher is fixed a pad to make a watertight joint
between itself and the neck of the bottle and the liquid passes through the stopper
and pusher.
In another modification, the liquid is delivered at the side of the neck of the
bottle to provide a more convenient method of pouring out.
The invention is illustrated upon the accompanying drawings whereon,―
Figure 1 is a section of a bottle neck fitted with the stopper and shewing the
same closed and the rubber ring fixed to the stopper.
Figure 2 is a plan of the top of the stopper.
Figure 3 is a section of a bottle neck fitted with the stopper, and shewing the
same open and with the rubber ring fixed to the bottle.
Figure 4 is a cross section on line E-F Figure 3.
Figure 5 is a section of a bottle neck fitted with the spring stopper and shewing
the same closed.
Figure 6 is a cross section on line A-B Figure 5.
Figure 7 is a section of a bottle neck fitted with the spring stopper and pusher,
and shewing the same open.
Figure 8 is a cross section on line C-D Figure 5.
Figure 9 is a section of a bottle neck fitted with the spring stopper and pusher
and having a side delivery and shewing the valve closed.
Figure 10 is a plan of the top of the neck of the same.
Figure 11 is a view similar to Figure 9 but sbewing the valve open.

page_text: 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. A bottle having a neck with an interior screw thread and a hollow stopper."
similarly screwed on its outside to engage in the neck of the bottle conical collars
upon the stopper to hold washers for making joints and lateral openings in the.
stopper, substantially as set forth herein.
2. A bottle having a neck with an interior screw thread and washer, a hollow
stopper similarly screwed on its outside to engage in the neck of the bottle, a.
bevelled collar at its upper end to hold a washer and a conical collar at its lower-
end to form joint with the washer in the neck of the bottle, substantially as set.
forth.
3. A bottle having a neck with an interior screw thread and a hollow stopper-
similarly screwed on its outside to engage in the neck of the bottle, conical collars.
upon the stopper and a disc to fit upon the flat sided head of the stopper,
substantially as set forth.
4. A bottle having a neck provided with a washer, a hollow stopper having-
lateral openings and a conical bottom to make joint with such washer, a spring to-
keep the stopper pressed against the washer, substantially as and for the purposes..
set forth.
5. A bottle having a neck provided with a washer, a hollow stopper having-
lateral openings and a conical bottom to make joint with such washer, a spring to.
keep the stopper pressed against the washer, lugs upon the stopper to take beneath
a collar formed on the interior of the neck, substantially as and for the purposes set.
forth.
6. A bottle having a neck provided with a washer and a side spout, a spherical.
stopper to make joint with such washer, a spring to keep the stopper pressc.l.
against the washer, lugs upon the stopper to take beneath a collar formed on the
interior of the neck, substantially as and for the purposes set forth.
7. The improvements in bottles and stoppers therefor consisting of parts constructed..
arranged and operating substantially as and for the purposes described herein and.
illustrated on the accompanying drawings.
