COMPLETE SPECIFICATION.
An Improved Bottle-stoppering Device.
I, JACOB MENKE, Merchant of, 207, Avenue du Commerce, Antwerp, in the
kingdom of Belgium, do hereby declare the nature of the said 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 an improved bottle closing device which is applicable
to all kinds of bottles intended to be filled with sparkling beverages, and possesses
the advantages of being easily produced, absolutely tight and always ready for
operation. Tight joint is made by the improved device not only above or at the
mouth of the bottle but also between the stoppering device and the bottle lip or
flange.
Two modifications of the Invention are illustrated on the accompanying drawings.
Figs. 1, to, 4, representing one thereof, and Figs. 5, to 8, representing the other.
Fig. 1, represents an elevation, and Fig. 2, a sectional elevation. Fig. 3, represents
a plan view of the bottle top, and Fig. 4, represents a section through the bottle and
stoppering device, on the line, A, B, Fig. 2.
Figs. 5, to, 8, represent a modification of Figs. 1, to, 4, representing the addition
of a special cap which is passed over the stoppering cap and bottle neck and secures
the whole.
Fig. 5, represents a sectional elevation, and Fig. 6, an elevation. Fig. 7, is an
under plan view of the cover and cap; and Fig. 8, represents a section on the
line, C, D, Fig. 6. <
On
In the improved stoppering device, the neck, a, of the bottle is formed with the
usual lip or flange, b, the top of which slightly slanting, and is fitted with a washer, c,
of leather or other suitable material which will form a tight joint with the cover.
the upper cylindrical part of the bottle-neck two wedge shaped flanges, e, are moulded
which serve for projections, f, on the cover, g, to bear against. The cover g, has on
its upper inner part, h, a bulge covered by a cork washer, i. The latter bears against
the top, k, of the bottle neck and makes a tight joint between it and the cover.
second tight joint is made as above stated by the leather washer, c.
A
Such closing device is easily fitted, easily removed, very cleanly and possesses the
advantage of the cover making a tight joint both on the top of the bottle and on the
edge of the flange. In order further to secure the cover, 9, in position, a cap, 1, may
be slipped over it, as shown in Figs. 5, to, 8. The cap, 1, is fitted with studs or pro-
jections, m, which, while being passed over the cover, g, and into position, slide in
suitable grooves, n, formed in the bottle neck.
If now the cap is turned through a small part of a revolution the studs, m, will bear
against the glass ribs, o, left between the grooves, n, thereby preventing the cover, 9,
from coming off accidentally. To remove the cover, the cap, t, must first be so turned
that the projections, m, coincide with the grooves, n, on the bottle neck.
The cover, g, may be made of glass, metal, wood or of other suitable material; the
cap, l, is preferably made of metal.
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. A bottle closing device characterized by the wedge shaped bearing surfaces, e,
provided on the bottle neck, in conjunction with projections, f, on the cover, g,
effective in making tight joint with the bottle neck by a disc, i, and with a sur-

page_text: 2. The bottle closing device characterised in claim, 1, in combination with a cap, 1,
for securing the cover, g, formed with projections, m, which pass through grooves, n,
in a flange surrounding the bottle neck when the cap is slipped on, and bear against
intermediate projecting portions of such flange when the cap is partly turned.
