Improvements in or relating to Capsules or Stoppers for Bottles
and the like.
A communication from LOUIS BOUNEU, Glass Manufacturer, of 100 Rue Rogier,
Brussels, in the Kingdom of Belgium.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, 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 present invention relates to a means of hermetically closing or stoppering
bottles and like receptacles, by a capsule of metal or other suitable material, by
the arrangement of two bosses, studs, or projections upon the outside of the neck of
the vessel to be closed.
Figures 1 and 2 represent the shape and position of the bosses upon the bottle-
neck. The capsule, which is to close the mouth or opening of the vessel is
represented, from various points of view in Figures 3 to 6 ;
Figure 3 is a plan of the capsule as seen from above;
Figure 4 is a similar view taken from below;
Figure 5 is a side elevation, at right angles to a line joining the two bosses;
Figure 6 is a side elevation on the line of junction of the two bosses;
The enlargements or hollows in the inner surface of the capsule correspond
to the bosses a a on the bottle-neck, and enable the capsule to be placed over the
mouth of the bottle, so that the bosses penetrate into the recesses of the capsule.
All that is then needed is to partially rotate the capsule, whereby the bosses press
upon the sloping bottoms of the recesses or openings, in the cylindrical part of
the capsule, the top g of the capsule being pressed down upon the top of the
bottle-neck, until the bosses a slip into the resting-places, or notches, in the
bottom of the capsule-recesses bb;
Figure 5 represents a capsule, in place on the neck, with the bosses in the
position last described.
Figure 7 represents the capsule in vertical section, showing the case or shell f
with the lateral recesses, and the bosses or projecting studs a a of the bottle-neck
resting therein, while the closure is made secure by a cork-disc l, resting upon a
flexible or elastic backing or outer cover m made of rubber or other suitable
compressible material, at the top of the capsule.
A great advantage, is thus attained by the fluid contained in the vessel only
coming in contact with cork, while a hermetically closed joint is secured by the
elastic and compressible backing-disc m, arranged between the cork-disc 7 and the
closed top g of the capsule.
By means of a connecting piece, the capsule may be prevented from becoming
detached or lost from the bottle or other vessel, while, at the same time, a relative
motion of the two is still possible; that is to say, that the capsule is free to rotate
around the bottle-neck, from right to left or vice versa, after being depressed so as
to release the bosses, or raised to fix them, for the purpose of either operating the
closure or the reopening.
This securing device is represented, in various forms, in Figures 8 to 15; which
are all based upon the same principle being distinguished by a fastening ring n on

page_text: the botile, and a movable connection. The latter may consist of a linking-piece,
a spring or a chain, secured at one end to the capsule at 7, and at the other end r
to the encircling ring.
In the modifications represented in Figures 8, 10, 14 and 15 this ring is shown
as movable, so that it is free to move around the bottle-neck.
Figures 11 to 13 the ring is represented as fixed.
Figures 6 and 10 show two views of one form of this appliance, in which the
connecting piece p formed of a single metal strip, which at r, is secured by a
kind of hinge-joint ;
Figure 9 shows a perspective view of the ring;
Figures 11 and 12 show two views of another modification, on the same principle,
in which the connection p is made by a chain;
Figure 13 shows another form of the said chain;
Figures 14 and 15 show the connecting-piece pin the form of a band or flexible
plate, which acts after the manner of a spring, and is fastened linkwise at r.
Figure 6 shows the capsule, in the closed position, having a paper strip stuck
to and encircling it; this latter serves to control the capsule, and is obviously
advantageons, in so far as the paper-strip, which may also have the name etc. of
the firm delivering the closed vessel printed or stamped upon it, can be stuck fast
on the capsule as well as in the recesses of the same, and upon the bottle neck, so
that any opening of the capsule without tearing the paper is impossible.
Having now particularly described and ascertained the nature of this said
invention as communicated to me by my foreign correspondent, and in what manner
the same is to be performed, I declare that what I claim is :-
1. A capsule or stopper for bottles and the like having helical recesses enlarged
at the end and adapted to receive bosses or projecting studs such as a on the
bottle-neck substantially as and for the purpose described and illustrated in the
accompanying dmwings.
2. In a capsule or stopper for bottles and the like the combination with helical
recesses such as b of a cork-disc such as inside the capsule, and resting upon an
elastic support or backing such as m for the purpose of obtaining an air-tight
packing, allowing the enclosed fluid only to come in contact with the cork
substantially as described and illustrated in the accompanying drawings,
3. In a capsule or stopper for hottles and the like the combination with recesses
such as of a fastening apparatus for the capsule, comprising a ring such as non
the neck of the bottle, and a flexible or elastic band chain or the like connecting
the ring with the capsule for the purpose of preventing the separation or loss
of the capsule from the bottle while allowing it a certain freedom of motion
substantially as described and illustrated in the accompanying drawings.
Dated this 10th day of October 1895.
