PROVISIONAL SPECIFICATION.
Improvements in Means of Closing Bottles and Jars.
I ALFRED SAVIGEAR of No. 5 Prince Teck Buildings, Earls Court Road
London S.W. in the County of Middlesex, Cordial Manufacturer do hereby declare
the nature of this invention to be as follows:-
This invention relates to means of closing the necks of bottles or jars by the employ-
ment of an external cap or stopper containing a pad of any suitable material preferably
of cork.
For this purpose I form the neck of the bottle or jar with oppositely inclined
channels on opposite sides of its orifice at the exterior.
The cap or stopper above referred to may be formed in metal or of vulcanite or other
suitable material according to the nature of the liquid or articles to be contained in the
bottle or jar.
It is of a diameter sufficient to fit over the neck of the bottle or jar and has two or
more projections from its interior, the number of these projections depending upon the
number of the channels formed at the exterior of the orifice of the bottle or jar to be
fitted.
These projections engage with the channels formed at the exterior of the neck of
the bottle or jar in such a manner that a partial rotation of the cap or stopper will
cause it to be drawn down firmly, closing the orifice by means of the pad above
referred to.
The pitch or inclination of the channels should be such as to provide the required
adhesion with the said projections to maintain a pressure on the pad sufficient to close
the orifice hermetically and at the same time to allow the most rapid application and
removal of the cap or stopper for closing and opening the bottle or jar.
Dated this 29th day of January 1889.

Improvements in Means of Closing Bottles and Jars.
I ALFRED SAVIGEAR of No. 5 Prince Teck Buildings Earl's Court Road
London S.W. in the County of Middlesex Cordial 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 means of closing the necks of bottles or jars by the employ-
ment of an external cap or stopper containing a pad of any suitable material preferably
of cork.
For this purpose I form the neck of the bottle or jar with oppositely turned channels
on opposite sides of its orifice at the exterior.
The cap or stopper above referred to may be formed of metal or vulcanite or other
suitable material according to the nature of the liquid or articles to be contained in
the bottle or jar; it is of a diameter sufficient the fit over the neck of the bottle or jar
and has two or more projections from its interior, the number of these projections
depending upon the number of the channels formed at the exterior of the neck of
the bottle or jar to be fitted.
These projections engage with the channels formed at the exterior of the neck of
the bottle or jar in such a manner that a partial rotation of the cap or stopper will
cause it to be drawn down firmly, closing the orifice by means of the pad above
formed in

page_text: In the accompanying drawings Figure 1 is an elevation of a bottle neck made in
accordance with this invention. Figure 2s a plan of the same and Figure 3 is a
sectional elevation of the bottle cap or stopper. In all the figures the same part is
indicated by like letters of reference."
A is the bottle neck; B is the vertical channel rounded at the point C. from which
it is continued in a direction parallel with the upper part of the bottle neck; D is the
bottle cap or stopper containing a pad E and having projections G G¹ to engage in
the oppositely turned channels on opposite sides of the neck at the exterior so as to
retain the cap or stopper in position when closed.
.
The rounded shoulders C at the bend in the channels B engaging with the pro-
jections G G cause the cap or stopper to be drawn down by a partial rotation thereof
sufficiently to close the orifice hermetically by means of the pad E and at the same
time allow the most rapid application and removal of the cap or stopper for closing
and opening the bottle or jar.
t
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 of a bottle cap or stopper having projections G, with a bottle
having channels outside the neck of the bottle, to engage therewith, such channels
being carried vertically downward and inclining horizontally forming a curve C at the
junction of the vertical and horizontal path for the purpose set forth substantially as
described and illustrated by the accompanying drawings.
