Improvements in Bottles and Bottle-stoppers.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 :-
The object of the invention is to produce a bottle-stopper of such construction that
the bottle may at all times be closely or hermetically sealed and escape of gases
from confined liquid, or of the liquid itself, prevented under all circumstances.
With this object in view the invention consists essentially in a bottle-stopper
comprising a bottle-neck, provided with a continuous indentation, a stopper to be
placed in the bottle and provided with a corresponding indentation, the indentations
in the neck and in the stopper bring so formed that when the stopper is placed in
position a continuous chamber is formed around the neck of the bottle, and a piece of
cork or other suitable material placed in the chamber, whereby, when the stopper is
drawn into place, the cork or the like is confined on all sides, and swelling from
moisture or other cause which would allow escape of gases or fluid is prevented ;
furthermore, the invention consists in a bottle-stopper comprising a stopper,
preferably of glass, having a lower tapering end, in combination with the bottle
having slanting sides at the portion of its neck with which the stopper comes in
contact, the said bottle being provided with inward-extending inclined projections.
I have illustrated the invention in the accompanying drawings, in which
Figure 1, is a sectional view of a bottle constructed in accordance with my
invention.
Figure 2, is a side view of the stopper removed from the bottle;
Figure 3 is a sectional view showing the construction of the neck of the bottle
adapting it for the reception of my stopper.
Figure 4 is an inverted plan view, showing the shank of the stopper and
illustrating the shape of the lower portion thereof.
In these drawings, A represents the neck of the bottle, in the upper portion of
which is a continuous channel or groove a, preferably circular in form.
B represents the stopper of the bottle, which is preferably of glass and is provided
on the under surface with a continuous groove b, the parts being so arranged that
when the stopper is in position, the groove a in the bottle and in the stopper form
three sides of a chamber of which the fourth side is formed by the depending portion
of the stopper which enters the bottle. In this chamber is placed a circular piece or
ring C, of cork or other suitable material which when compressed will form a water-
tight and practically air-tight joint between the stopper and the bottle. By the
construction of the parts, it will be seen that the ring, being placed in the circular
chamber, will be prevented from swelling or otherwise getting out of shape, and that
escape of liquid or gas from this cause will be impossible.
The lower portion of the stopper is made as shown, that is, tapering from a
short distance below the main cap-portion to a point from which point it enlarges
and assumes a shape corresponding to the contour of the inside of the bottle in
which it is to be placed.
On opposite sides of the bottle in which the stopper is placed and at a point
adjacent to the flaring portion of the stopper are upward-extending inclined
projections a. These projections are preferably slanting, and as they are pressed
into the neck of the bottle from the outside, the diameter of the neck at that
point is lessened. The stopper is in cross-section rounded oblong and is inserted

page_text: with its longer portion against the curved portion of the neck. By turning the
stopper slightly, the flaring portion of the stopper is brought into contact with
the Hattened portions and as these are slanting the more the stoppers are turned
the tighter it will be wedged.
By making the stopper of the form shown, projections which are liable to become
broken by pressure of tightening are avoided and a strong stem capable of with-
standing pressure is provided, for bearing against the bottle in the act of tightening
the stopper.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondent I declare that what I claim is :-
1. The combination with a bottle neck provided on its upper edge with a
continuous indentation, of a stopper having on the lower face of its cap a corre-
sponding indentation and a ring of cork or the like confined between the two,
substantially as described.
2. The combination with a bottle having the continuous groove in the upper
face of its neck, and having the inward extending inclined projections of the stopper
having the continuous indentation in the lower face of its cap, and a ring of cork or
the like interposed between the stopper and the bottle, substantially as described.
Dated this 4th day of November 1890.
