Improvements in Bottles, Jars, and the like, and in Stoppers therefor,
I, JAMES COBDEN TRUEMAN, of Birchwood Park Road, Swanley, in the County
of Kent, Contractor, do hereby declare the nature of this invention to be as
follows:
My invention has for its object improved means for closing and rendering
air-tight the mouths or outlets of bottles, jars, and like vessels of glass or other
material.
For this purpose I form in the interior of the neck of a bottle, or equivalent
part in other vessels, an annular seating and above this or nearer the outlet
I form a projecting ring of slightly less width than the annular seating, and this
ring I cut away at two or more equidistant points, preferably to such an extent
that the spaces so formed are equal in extent to the remaining segments of the
ring.
With a bottle or other vessel having the interior of its neck, or equivalent
part thereof so formed I employ a plug or stopper, preferably of the same
material as the bottle, and of a diameter equal to that of the inner edge of the
annular seating in the neck or equivalent part of the bottle or like vessel, or
nearly so. On this plug or stopper I form a projecting annular seating equal
in width to the difference between the diameters of the inner edges of the
annular seating and the ring in the neck or equivalent part of the bottle or
other vessel and having an inelined under surface.
Immediately above this annular seating on the plug are formed projecting
lugs equal in number, size, and shape to the spaces formed by cutting away the
annular ring in the bottle neck or equivalent part, and these projecting lugs I form
with their upper surfaces so curved that they increase in thickness from their
ends towards the middle.
In closing a bottle, jar, or the like, the plug is arranged so that the lugs
thereon will pass between the segments of the ring in the bottle neck, or equi-
valent part, and the plug is then pressed inwards and turned, thus bringing
the lugs on it under the segments of the ring in the bottle neck, or equivalent
part, and at the same time causing the seating on the plug to press against a
ring of rubber or the like material previously placed upon the seating in the
neck of the bottle, or equivalent part, expanding said ring and making an air-
tight joint.

I, JAMES COBDEN TRUEMAN, of Birchwood Park Road, Swanley, in the County
of Kent, Contractor, 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: --
My invention has for its object improved means for closing and rendering
air-tight the mouths or outlets of bottles, jars, and like vessels of glass or other
material.
For this purpose I form in the interior of the neck of a bottle, or equivalent
part in other vessels, an annular seating and above this or nearer the outlet
I form a projecting ring of slightly less width than the annular seating, and this
ring cut away at two or more equidistant points, preferably so that the spaces
formed are equal in extent to the remaining segments of the ring.
With a bottle or other vessel having the interior of its neck, or equivalent
part thereof so formed I employ a plug, or stopper, preferably of the same
material as the bottle, but not necessarily so, as other material may be used
when desired. This stopper is of a diameter equal to that of the inner edge
of the annular seating in the neck of the bottle, or equivalent part of other
vessels, or nearly so. On this plug or stopper I form a projecting annular
seating equal in width to the difference between the diameters of the inner
edges of the annular seating and the ring in the neck or equivalent part of the
bottle or other vessel, and having an inclined under surface.
Immediately above this annular seating on the plug are formed projecting
lugs equal in number, size and shape to the spaces formed by cutting away the
ring in the bottle neck or equivalent part, and these projecting lugs I form
with their upper surfaces so curved that they increase in thickness from their
ends towards the middle.
My invention will be better understood by reference to the accompanying
drawings, of which
Fig. 1 is an elevation of a part of a bottle neck and a plug, the former being
in section.
Fig. 2 is a plan of the bottle neck with plug removed,
Fig. 3 an elevation of the plug detached, and,
Fig.
a sectional plan on line AA, Fig. 3.
As shown, Figs. 1 and 2, the interior of the bottle neck is formed with annular
seating and above this with a projecting ridge or ring b of slightly less internal
diameter, and cut away at diametrically opposite points, Fig. 2. preferably so
that the spaces formed are equal to the remaining segments of the ring
When desired, however, the ring may be cut away at three or more equidistant
points.
The stopper, Figs. 1, 3 and 4, of such bottle neck, is of the same, or slightly
iess, diameter than the inner diameter of the ring b and has formed on it a
projecting annular seating c equal in width to the difference between the inner
diameters of the seating a and ring b, and has an inclined under surface.
Immediately above this annular seating on the plug are formed projecting
lugs equal in number, dimensions, and shape to the spaces formed by cutting
away the ring and these lugs are formed with their upper surfaces curved or
inclined from the centre towards each end.
In closing a bottle, jar, or the like, the plug is arranged so that the lugs d
will pass between the segments of the ring or equivalent part, and the plug is
tlien pressed inwards and turned, thus bringing the lugs on it under the seg-

page_text: ments of the ring in the bottle neck or equivalent part and at the same time
causing the seating on the plug to press against a ring of rubber e or the like
material previously placed upon the seating a, or equivalent part, expanding
said ring, and making an air-tight joint.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1
The means for closing bottles, jars, and the like, consisting of the formation
in the neck or equivalent part of such bottle, jar, or the like, of an annular
seating, and above this of a projecting ridge or ring cut away at equidistant points,
and the formation on the stopper of such bottle, jar, or the like, of an annular
seating e and projecting lugs substantially as described and illustrated by
the accompanying drawings.
