PROVISIONAL SPECIFICATION.
Improvements in Bottles, and Stoppers therefor.
I, STAFFORD HILL, of the Firm of De Luca, Hill & Co. of 6 and 7 Long Lane,
Aldersgate Street, in the City of London, Glass Bottle Manufacturers and
Merchants, do hereby declare the nature of this invention to be as follows:-
Bottles which are stoppered by a glass ball or the like, within the bottle, seating
itself on an elastic ring in the nozzle, generally require that the ball or stopper be
inserted into the bottle before the nozzle is finished and while the glass is still hot,
and are provided with internal projections or other arrangements for preventing
the stopper returning to the nozzle and again stopping it while the contents of the
bottle is being poured out.
Now my invention is intended to render practicable the insertion of the ball
after the nozzle is finished and cold, and to obviate the necessity for the internal
projections above named, and otherwise to improve and simplify the construction
of bottles so stoppered.
According to my invention I construct the internal surface of the nozzle and
neck of the bottle of cylindrical form and make therein an annular groove for the
reception of the india rubber or other ring hereinafter described.
The glass ball or stopper, or ball or stopper of other material, is made of such
size as just to pass freely through the nozzle and neck into the bottle, and if of
glass or other heavy material is made hollow, or is made solid of lighter material,
in either case so as to float.
The ring of rubber or other like material which forms the seating for the stopper
is made of such form and dimensions that while part of it fits evenly into the
groove, the internal face of the ring projects into the opening of the neck thereby
Icaving too small an opening for the stopper to pass through.
The ring is preferably made with a portion of it forming an annular fillet or
rim of such a size as to fit smoothly the inner surface of the neck or nozzle of the
bottle and when made in this shape this portion is of such substance that no probable
amount of pressure due to compressed gases or the like can compress it against the
glass sufficiently to allow the stopper to pass it, but the form of the transverse
section of the ring admits of considerable variation.
It will be seen therefore that after the bottle is finished and cold, the glass or
other stopper may be put into it, and the cushion ring inserted in the neck and into
the annular groove prepared for it, and with the fillet or rim part of it, if any, lying
on the internal surface of the neck adjacent to the groove.
As the stopper is made to float it is not necessary to invert my bottles to fill
them for as the contents rises the stopper floats up into the neck and to the seat,
against which it is pressed and retained by the confined gas.
When the bottle is being emptied, if the nozzle be held sufficiently downwards,
the stopper being specifically lighter than the fluid, floats away from the neck, and
thus leaves it free for the unobstructed flow of the contents.

page_text: I, STAFFORD HILL, of the Firm of De Luca Hill & Co., of 6 and 7, Long Lane,
Aldersgate Street, in the City of London, Glass Bottle Manufacturers and
Merchants, 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 :-
Bottles which are stoppered by a glass ball, or the like, within the bottle, seating
itself on an elastic ring in the nozzle, generally require that the ball or stopper
be inserted into the bottle before the nozzle is finished and while the glass is
still hot.
Now my invention is intended to render practicable the insertion of the stopper
after the nozzle is finished and cold, and otherwise to improve and simplify the
construction of bottles so stoppered.
The principal feature of novelty in my invention is the form of the rubber, or
other ring which forms the seating for the stopper and which according to my
invention is made with a rim, or fillet, which presents the passage by it of the
stopper.
According to my invention I construct the internal surface of the nozzle or neck
of the bottle of cylindrical, or nearly cylindrical form and make therein an
annular groove for the reception of the india rubber or other ring hereinafter
described.
The glass ball, or stopper, or ball or stopper of other material is made of such
size as just to pass freely through the part of the nozzle above the annular groove,
and into the bottle.
The ring which forms the seating for the stopper is made with an annular rim,
or fillet, of such size as to fit smoothly and extend a short distance in the nozzle
beyond the groove so that although the stopper when pressed outwards might
perhaps sufficiently compress the ring into the groove to allow the stopper to pass
that part of it, such pressure as may be due to compressed gas, or the like, cannot
compress the rim, or fillet, sufficiently to allow the stopper to pass because the
latter has no groove at the back of it into which it can be compressed, and the
stopper is thus effectually prevented from passing the ring.
It will be seen therefore that after the bottle is finished and cold the glass, or
other stopper may be put into it and the seating ring inserted in the neck and
into the annular groove prepared for it, with the fillet or rim part of it lying on
the internal surface of the neck adjacent to the groove.
The stopper may be made of glass, or of other material, and if the stopper be
made of a material which will float, such for instance as ebonite, it will not be
necessary to invert my bottles in order to fill them, for as the contents rises the
stopper floats up into the neck and to the seating-ring against which it is pressed
and retained by the confined gas.
If a floating-stopper is used it floats away from the neck when the bottle is being
emptied and thus leaves it free for the unobstructed flow of the contents, but
there may conveniently be made some indentations in the neck or otherwise to
check the too ready return of the stopper to the nozzle.
In the accompanying drawings
Fig. 1, is a vertical section of the upper portion of a bottle according to my
invention with a ring in place and a ball closing the opening.
Fig. 2, is an elevation of the ring. Fig. 3, a section of the same and
Fig. 4, a representation of the upper portion of such a bottle.
A is the nozzle of the bottle; b is the annular groove therein for the reception
of the ring. The internal diameter of the nozzle above the groove 6 is less than it

page_text: is below it, both parts being cylindrical or nearly so. C is the ring preferably of
vulcanized rubber and d the annular fillet, or rim, which when in the neck of the
bottle cannot be so compressed as to allow the stopper to pass it, as the stopper is
of such diameter as only just to pass freely in and out when the ring is not there;
g, is a small annular projection, or fillet, which serves to facilitate and render more
perfect the seating of the ball in the ring. The stopper E, shown in the drawings,
is globular but it may be of other than globular form provided it be so arranged as
to seat itself correctly against the ring. ff, are indentations forming internal
projections of which I prefer to make three, in or about the base of the neck of the
bottle which serve to prevent the too ready return of the stopper into the nozzle
when the contents of the bottle are being poured out.
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 1
claim is:
1. The improvements in stoppering bottles hereinbefore described and set forth.
2. The hereinbefore described arrangement for stoppering bottles containing
aerated and effervescing liquids, consisting of a ring of cushioning material fitting
into an annular groove in the neck of the bottle and having a rim or portion
extending beyond the groove and lying in the nozzle together with a stopper of
such size as to almost fit the neck but so that it can be passed into the bottle, before
the ring is inserted, substantially as described.
3. In bottles for containing aerated-liquids, a seating ring C having a rim,
or fillet, d, substantially as described and shown in the drawings and for the purpose
set forth.
