PROVISIONAL SPECIFICATION.
Improvements in or relating to Glass Bottles.
I, CHRISTIAN HAMILTON GRAY of The Indiarubber, Guttapercha, and
Telegraph Works Company Limited, Silvertown, Essex, Indiarubber Manu-
facturer, do hereby declare the nature of this invention to be as follows :-
This invention relates to a means of preventing glass bottles from breaking at
the neck or stopper end. At present as is well known most bottles of ordinary
shape and construction are liable to break in removing the cork or stopper, and to
prevent this I apply to any desired part or parts of the neck or end of the bottle
one or more protecting rings, caps or equivalent of suitable material say for
example ebonite, or other form of rubber or the like, wood, ivory, celluloid,
soft metal, papier maché, vulcanised fibre, and other materials of a more or less
similar nature. This protector has the effect of mitigating the force of any blow
which a portion of the bottle may receive besides to some extent strengthening and
supporting the glass.
•
The cap may be applied in a variety of ways. In a simple form the end of the
bottle neck would be provided with an undercut or recessed groove into which a
ring say of ebonite would be sprung or shrunk on. In another case a slight
groove is formed in the bottle and a ring, circular in cross section, is sprung or
shrunk into this. In other cases the cap is made to cover the bottle both inside
and out, and where screw stoppers are used the thread may be formed in the
protector, either outside or in according to the stopper or cap that is employed.
In another case the cap would protect the absolute end and be turned slightly over
as a bead on to the outside of the bottle neck. The protector may be formed of
two or more layers, for instance a hard one outside and a soft one inside.

Improvements in or relating to Glass Bottles.
I, CHRISTIAN HAMILTON GRAY of The Indiarubber, Guttapercha, and
Telegraph Works Company Limited, Silvertown, in the County of Essex,
Indiarubber Manufacturer, 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 :-
This invention relates to a means of preventing glass bottles from breaking at
the neck or stopper end. At present, as is well known, most bottles of ordinary
shape and construction are liable to break in removing the cork or stopper, and to
prevent this I apply to any desired part or parts of the neck or end of the bottle
one or more protecting rings, caps or equivalent of suitable material say for
example ebonite, or other form of rubber or the like, wood, ivory, celluloid, soft
metal, papier maché, vulcanised fibre, and other materials of a more or less similar
nature. This protector has the effect of mitigating the force of any blow which a
portion of the bottle may receive besides to some extent strengthening and
supporting the glass.

The cap may be applied in a variety of ways. In a simple form the end of
the bottle neck would be provided with an undercut or recessed groove into
which a ring say of ebonite would be sprung or shrunk on.
In another case a
slight groove is formed in the bottle and a ring, circular in cross section, is
sprung or shrunk into this. In other cases the cap is made to cover the bottle
both inside and out, and where screw stoppers are used the thread may be
formed in the protector, either outside or in according to the stopper or cap that
is employed. In another case the cap would protect the absolute end and be
turned slightly over as a bead on to the outside of the bottle neck. The protector
may be formed of two or more layers, for instance a hard one outside and a soft
one inside.
The accompanying drawings serve to illustrate how this invention may be
carried into effect; the figures are all vertical sections through the necks of
bottles.
In Figure 1 the neck of the bottle A is provided with an undercut or recessed
groove into which a ring B of ebonite or other suitable material is placed.
In Figure 2 a slight groove or recess is formed in the neck of the bottle and a
ring B circular in cross section is sprung or shrunk into this.
In Figures 3 and 4, a cap or cover C is so arranged as to cover the neck of the
bottle both inside and out and where screw stoppers are used the thread may be
formed in this protector as shown for example in Figure 4.
In Figure 5 instead of employing as in the other figures an ordinary screw
stopper to screw inside the neck of the bottle, a cap or cover D is used to screw
on to the outside of the bottle neck; the cap D may be of comparatively soft
rubber and serves to protect the neck of the bottle even more effectually than the
rings B in Figures 1 and 2. In this arrangement also I may employ a covering of
suitable material say vulcanite F around the neck of the bottle, and formed with
the necessary screw thread so that the cover D screws on to the vulcanite F. J is
a ring or washer contained in the cap D and adapted to fit against the end of the
neck so as to make a tight joint between the cap and the bottle.
In Figure 6 the cap or cover C is employed to cover just the extreme end of the
bottle neck it being turned over slightly both inside and outside.
In Figure 7 the protector is made in the form of a cap or cover C of two layers
of material, the outer one C hard, and the inner one E soft, while in Figure 8 this
arrangement is reversed, the inner layer C being the hard one and the outer layer E
the soft one.
Figure 9 represents two arrangements, upon the left-hand side of the centre line
the cover C is turned down inwardly over the end of the bottle neck at C¹ while
at the right hand side of the figure it is carried forward in a plane perpendicular
to the axis of the bottle, the open end of the bottle in this latter case being
carried forward to meet it and thus prevent the edge C' from projecting.
In Figure 10 an ordinary cork G is shown in the bottle and the cover C is
provided with a number of little lugs H adapted to engage with the shoulder I
formed upon the outside of the bottle neck.
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. Protecting the neck of a bottle from damage by means of a ring cover or
cap such as BC or D.
2. A device for protecting the necks of bottles consisting of a ring cover or cap
such as BC or D substantially as described and illustrated in the accompanying
drawings.
3. The combination with the neck of a bottle of a ring cover or cap such as B C
or D for the purpose of protecting the neck of the bottle from damage.
4. The combination with the neck of a hottle of a protecting device such as C
extending over the outside or inside of the neck and provided with a screw thread

of the accompanying drawings.
5. The combination with the neck of a bottle of a protecting device such as F
upon the outside of the neck and provided with a screw thread upon which the cap
or cover screws substantially as described and illustrated in Figure 5 of the
accompanying drawings.
