Improvements in Means or Apparatus Employed in Aerating Water
and other Liquids in Bottles and the like.
I, EMILE STERNÉ, of 8, Rue Mogador Prolongé, Paris, in the Republic of France,
Engineer, do hereby declare the nature of this invention to be as follows;-
The object of the present invention is to construct stoppers or apparatus for
aerating liquids by means of compressed or liquefied gases contained in capsules
or containers. For this purpose I provide a stopper with means for making a
hermetic joint with the neck of a bottle or the like and I furnish the same with
a support for the capsule and means for liberating the gas from the latter.
The stopper is also fitted or formed on the exterior with an air chamber communi-
cating with the interior of the bottle or the like.
Thus when the gas is liberated from the capsule the air chamber serves as a
safety chamber and prevents undue pressure in the bottle or the like.

Improvements in Means or Apparatus Employed in Aerating Water
and other Liquids in Bottles and the like.
I, EMILE STERNÉ, of 8, Rue Mogador Prolongée, Paris, in the Republic of France,
Engineer, 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 present invention is an improvement in means or apparatus
employed in aerating water and other liquids in bottles and the like, with a view
to the prevention of excessive pressure within the bottle and consequent rupture
of the latter and injury to the person.
According to my invention I form or attach to the stopper or apparatus employed
in aerating liquids in bottles and the like, an external air chamber into which
the gas from the capsule or container first passes when liberated from the latter.
My invention is illustrated in the accompanying drawings, in which:-
Fig. 1 is a section of a bottle-neck fitted with a stopper or aerating apparatus
provided with my improvements, and
Figs. 2 and 3 are upper and underside views of part thereof.
a is the neck of a bottle or the like which, with the construction of stopper or
aerating apparatus shown, is provided with an external screw thread, on to which
ED 077

page_text: the part b cf the stopper is screwed, but other suitable arrangements may be
employed for fixing the stopper or aerating apparatus to the bottle.
The stopper is formed with an external air chamber b' of capacity sufficient to
prevent the gas, when liberated from the capsule or container c, developing an
undue pressure within the bottle.
In charging the bottle with water or other liquid I fill it to within a very short
distance from the top of the neck a (say, half an inch or so), so that no room is left
for the entrance of gas within the bottle; then, when the gas is liberated from the
capsule or container, I shake the bottle well in order that the gas may as far as
possible be absorbed by the liquid contained within the bottle.
In the example shown the stopper is provided with a fixed internal ring 62 screw-
threaded internally to receive a disc d provided with openings d to permit of free
communication between the bottle and the air chamber band formed with a
central projection ², on to which is screwed a flanged cap . which retains the
perforating pin in position and, by its flange, secures the capsule-holder e from
becoming separated from the stopper, and at the same time permits of motion of
such holder e between the flange of the cap and the body of the disc d.
The capsule-holder e is formed with an opening el in one side thereof to permit
the ready insertion of a capsule and the removal of the latter when discharged
and it has a continuous or ring portion 2 at its lower end to hold the capsule c
against the pressure of the perforating pin d.
In use a capsule e is placed within the holder e, the stopper is then applied to
the bottle or the like and is screwed on to the neck thereof; in this operation
the flange of the capsule-holder e becomes supported by the seat a¹ at the top
of the bottle-neck, a tight joint is made between the stopper and the bottle by the
ring compressing a rubber washer f between it and the top of the bottle-neck
and, in the final portion of the action of screwing the stopper on to the bottle-
neck, the pin d is caused to perforate the capsule c.
When it is desired to clean the interior of the air chamber b', the disc d can
be readily unscrewed from the ring b².
I would here remark that although I have shown my invention applied to a
stopper fitted with a capsule-holder and a perforator as above described, it may
be applied to other arrangements of apparatus for holding a capsul and for
liberating the gas from the latter, whether by means of a valve or by means of
dissolution of a mass of soluble or decomposable material filling an aperture in the
capsule as set forth in the specification of my Patent No. 15,402 of the year 1897.
It will be evident that the air chamber may be of other form than that shown
in the drawing, so long as it has sufficient capacity for the purpose described, and
I would further remark that the stopper may be secured to the bottle by other
means than that shown.
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:
In apparatus employed in aerating water and other liquids in bottles and the like,
the combination with a stopper having a holder for a gas-containing capsule; means
for liberating the gas from such capsule, and means for securing the stopper to the
bottle-neck, of an air or safety chamber on the exterior of such stopper and having
free communication with the interior of the bottle, whereby the gas liberated from
the capsule enters the air or safety chamber, substantially as and for the purpose
described.
