PROVISIONAL SPECIFICATION.
Improvements in Bottles, Bottle Stoppers, and Openers.
I, WILLIAM PRIESSNITZ BONWICK, of 59 Blomfield Road, Maida Hill, in the
County of Middlesex, Engineer do hereby declare the nature of this invention to
be as follows:-
In the Specifications of former Letters Patent granted to me dated 22 July
1889 No. 11674 there are described constructions of bottles and stoppers therefor
according to which each stopper comprises a lower part forming a valve, an upper
part constituting a knob, a part constituting a connecting stem, two groove like
channels formed at opposite sides of the stopper and each made partly in the knob
and partly in the stem and an annular groove formed by and between the valve
and knob and stem, the said stopper being held in place within the bottle neck, by
a ring or washer of elastic material such as india rubber that is fitted partly within
the annular groove in the stopper and partly within an annular groove formed in
the bottles neck.
Now iny present invention has for object to provide a bottle fitted with a stopper
of the kind referred to or modified as hereinafter described, with a simple and
inexpensive construction and arrangement of opener whereby the stopper can be
easily and readily pressed inward to open it and permit of the contents of the
bottle being wholly or partly withdrawn, and which shall not be liable to become
displaced and lost.
r
For this purpose I construct the exterior of the bottle ring or neck with a
screw thread part thread or cam-like projection or projections, to which is fitted
an opener consisting of a tube formed at its outer end with an inwardly bent part
or parts adapted to extend into the bottle mouth, the arrangement being such that
by turning the said opener in one direction its inwardly bent part or parts will be
caused to act upon and press the stopper inward sufficiently to open it, and by
turning the opener in the other direction the said part or parts will be withdrawn
and permit the stopper to automatically close.
As will be obvious the form of the exterior of the bottle ring or neck and of
the opener to engage therewith can be variously modified.
In carrying out my invention I consider it advantageous to employ a stopper of
the type hereinbefore referred to but constructed with a central discharge passage
instead of lateral discharge channels formed at opposite sides of the stopper, and
with one or more lateral exit passages connecting with said central passage and
controlled by the elastic ring or washer by which the stopper is held in place
wholly within the bottle mouth. By this construction of stopper the aerated
contents of the bottle will be able to issue in a single central stream and thus be
subjected to less friction and disturbance than when two discharge passages are
used.
When a bottle stopper of this modified construction is used the inwardly bent
portion of the opener may advantageously be made tubular and of bell mouthed
form.

I, WILLIAM PRIESSNITZ BONWICK, of 59 Blomfield Road, Maida Hill, in the
County of Middlesex, Engineer, 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 :-
In the Specification of former Letters Patent granted to me dated 22 July 1889
No. 11,674, there are described constructions of bottles and stoppers therefor,
according to which each stopper comprises a lower part forming a valve, an upper
part constituting a knob, a part constituting a connecting stem, two groove-like
channels formed at opposite sides of the stopper and each made partly in the knob
and partly in the stem, and an annular groove formed by and between the valve
and knob and stem, the said stopper being held in place within the bottle neck by
a ring or washer of elastic material, such as india-rubber, that is fitted partly within
the annular groove in the stopper and partly within an annular groove formed in
the bottle neck.
Now my present invention has for object to provide a bottle fitted with a stopper
of the kind referred to, or modified as hereinafter described, with a simple and
inexpensive construction and arrangement of opener whereby the stopper can be
easily and readily pressed inward to open it and permit of the contents of the
bottle being wholly or partly withdrawn, and which shall not be liable to become
displaced and lost."
The accompanying drawing shows partly in vertical section and partly in
elevation, a bottle, bottle stopper and opener constructed and arranged according to
this invention, the opener being applied to the neck of the bottle, which is shown
inverted, and the stopper being shown in the opened position.
1 is the bottle neck formed with an internal annular groove 2 to partly receive
the ring or washer 3 of the bottle stopper 3* as described in my said former
Specification. The exterior of this bottle neck according to my present invention
is provided with a screw thread + that may be of the rounded shape shown. In
order that the external screw threads 4 of different bottles shall all be of the
same or approximately the same external diameter, they should be formed by
being blown in the bottle mould, for which purpose the said mould is formed
with a screw thread so arranged that the resulting screw thread on the bottle neck
shall be about ths of an inch below the wetting-off mark. After the screw
thread has been thus formed by blowing and the bottle wet off or removed from
the blowing iron, a ring of molten metal is put on the extreme edge of the bottle
neck instead of around it as usual, and this ring treated by a tool in the ordinary
way to form the internal annular groove 2 and to impart the desired form to the
bottle mouth, the external screw thread acting at this time as a stop to prevent the
said tool entering the bottle mouth far enough to cause the cutters that form
the internal annular groove 2 to come in contact with the end of the bottle neck
that has already become set, as has heretofore frequently been the case and which
results in the formation of an imperfect groove. To the external screw thread
thus formed is fitted an opener consisting of a tube 5 formed at its upper or outer
end with an inwardly bent or projecting part 5* adapted to extend into the bottle
mouth as shown, the arrangement being such that by turning the said opener in
one direction, the projecting part 5 will be caused to act upon and press the
stopper 3 inward sufficiently to open the discharge passage or passages therein
and by turning the opener in the other direction the part 5 will be withdrawn and
permit the stopper to be automatically closed by the action of its elastic ring or
washer 3. In the example illustrated, the opener is formed of a metal tube 5
closed at one end by a wooden plug 5 that is formed with the inwardly projecting

page_text: part 5 and with a central passage 5° to permit of the discharge, through the-
opener, of any desired portion of the contents of the bottle.
To allow of the rapid escape of any liquid which may be discharged around the
outer edge of the part 5, inclined passages 5d are provided in the plug. These
passages instead of being inclined so as to lead into the central opening as showi,.
may pass straight through the wooden plug, or grooves may be formed in the
periphery of the said plug so as to leave passages between it and the tube 5.
The lower or inuer end portion of the tube 5 is formed with an internal screw
thread 5ª corresponding to the screw, thread 4 upon the exterior of the bottle-
neck.
As will be obvious, the form of the exterior of the bottle neck and of the
opener to engage therewith can be variously modified. Thus instead of the bottle
neck and opener being formed as shewn, one or both of them may be formed with
one or more part threads or cam-like projections, the arrangement in each case
being such that by turning the opener in one direction it will be caused to move.
end ways on the bottle neck and depress the stopper and when moved in the opposite
direction will release the stopper and permit it to close.
Openers constructed as above described may be conne ted to a ring, it may be-
by means of arms that form a bottle holder, and can be attached to a wall or
counter, the arrangement being such that when the bottle is placed in the holder.
in an inverted position and turned in one direction to the required extent, the
above mentioned screw threads or part threads on the opener and bottle neck will
engage and by moving the latter towards the former will cause the projecting
part 5 of the opener to act against the stopper and force the same inwards so
that liquid can escape from the bottle into a receptacle held beneath it. Upon the
bottle being turned in the other direction it will be screwed away from the said
projecting part and the stopper permitted to automatically move outward so as to
close the bottle.
In carrying out my invention I consider it advantageous to employ a stopper of
the type hereinbefore referred to but constructed as shewu with a ceutral discharge
passage 6 instead of lateral discharge channels formed at opposite sides of the
stopper, and with one or more lateral exit openings 6 connecting with said central
passage and controlled by the elastic ring or washer 3 by which the stopper is
held in place wholly within the bottle mouth. I prefer to employ only one lateral
opening 6, as the employment of two or more such openings renders the stopper
somewhat weak.
By the construction of stopper described, the aerated contents of the bottle will
be able to issue in a single central stream and thus be subjected to less friction and
disturbance than when two discharge passages are used. I prefer to form the-
flange 7 around the upper part of the knob of the stopper in such a manner as to
admit of a tool for removing the rubber ring being easily passed between the
inside of the bottle neck and the knob of the stopper. For this purpose the
flange may be cut away or flattened on one side as at 7", preferably, on the side
opposite to the opening 6; this construction renders the stopper less liable to be
broken whilst pushing the rubber ring into the bottle for the purpose of removing
the stopper.
Having now particularly described and ascertained the nature of the said inven--
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The construction of a bottle having an internal annular groove 2 for use
with a single elastic ring or washer and stopper of the kinds herein referred to,
with an external screw thread 4 or its equivalent blown upon the bottle neck
substantially as described and shown for the purpose specified.
2. The use in conjunction with a bottle and bottle stopper of the kinds referred
to in the preceding claim, of a bottle opener having an internal screw thread or
its equivalent adapted to engage the external screw thread or its equivalent on

page_text: the bottle neck and an inwardly bent or projecting part adapted to enter the
bottle mouth and depress the stopper therein when the opener is turned in one
direction and to release the stopper and permit it to close when moved in the
opposite direction substantially as described.
3. The combined bottle, bottle stopper and opener hereinbefore described with
reference to and shown in the drawings annexed.
the bottle neck and an inwardly bent or projecting part adapted to enter the
bottle mouth and depress the stopper therein when the opener is turned in one
direction and to release the stopper and permit it to close when moved in the
opposite direction substantially as described.
3. The combined bottle, bottle stopper and opener hereinbefore described with
reference to and shown in the drawings annexed.
Dated this 15th day of March 1894.
