Improvements in the Construction of Stoppers or Closing Devices
for Bottles and like Receptacles.
I, HENRI GUILLOU, of 208, Avenue du Maine, Paris, in the Republic of France,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-

This invention relates to an improved stopper or closing device applicable to the
interior of necks of ordinary bottles or like receptacles or in the interior of widened
necks of bottles or receptacles, the object of the invention, being to prevent such
bottles or receptacles from being re-filled after having once been emptied of their
contents.
In a stopper or, closing device constructed according to this invention a hollow
stopper, preferably of glass, porcelain, earthenware or like material, partly closed at
its lower,end by a diaphragm is provided, on the outside of its cylindrical part, with
a projection or flange enabling it to rest upon the top edge of the neck of the
receptacle..

Adjacent to the stopper and firmly connected therewith by means of a cement,
insoluble in water and other liquids that may be enclosed in the bottle are one or
two cylindrical rings of the same outer diameter as the outer cylindrical part of the '
stopper, the rings being likewise provided with a diaphragm which partly closes. or
blocks the bottom end of one of the said rings, and has a flanged edge serving to
prevent the parts below the stopper from being reached.
:
The stopper and the rings cemented thereto are ground into the neck, of
the receptacle, wherein they are subsequently cemented, after the bottle has been
filled..

A heavy clack-valve of glass, porcelain, earthenware or like material; surmounted
with a screw-threaded head by means of which the valve is held while being ground
on to the seat or narrowed portion of the bottle neck, is seated below the stopper in
the neck of the bottle and pressing on the valve is a metallic spiral spring of trun-
cated conical or cylindrical shape and of such a strength as to yield to the weight.of
the clack valve when the bottle is inverted.

Improvements in the Construction of Stoppers or Closing Devices
for Bottles and like Receptacles.
I, HENRI GUILLOU, of 208, Avenue du Maine, Paris, in, the Republic of France,
Mechanical Engineer, do hereby declare the nature of this invention and in what
Pri d

page_text: manner cae same is to be performed to be particularly described and ascertamed in
and by the following statement :-
This invention relates to an improved stopper or closing device, arranged in the
interior of the neck of bottles and other receptacles and serving to prevent such
bottles or receptacles from being re-filled with a liquid of any kind, after having once
been emptied.
This device is represented in various constructional forms in the accompanying
drawing, in which,
Fig. 1 is a vertical section of the said stopper or closing device applied to the
widened part of the neck of a bottle.
Figs. 1A and 1B are an elevation and plan respectively of a clack-valve used in
connection with the stopper.
Fig. 1 illustrates another form of construction in which the tail piece of the clack-
valve is, furnished with three channels..
Fig. 2, shows in vertical section a slightly modified construction of the stopper or
closing device, adapted to fit a large necked bottle.
Fig. 2 is a plan of the valve used therewith.
The same reference letters are used to indicate the same parts in all the figures.
The stopper or closing device consists firstly, of a hollow glass stopper b, provided
with a diaphragın 6º, partly closing the lower part of its circular section; further
with one, or two eylindrical glass rings 616, arranged in juxtaposition below the said
hollow body b, each ring 61 62 being provided with a diaphragin 60 which is preferably
furnished with a flange 63, serving to prevent any rod or the like from being intro-
duced into the clack-valve chamber. The stopper and rings as described being of a
uniform outer diameter, are united by a cement which is insoluble in water, and after
having been thus cemented together, they are ground into the neck a² of the bottle a
(Fig. 1) or into the inserted or fitted in neck q (Fig. 2). The stopper 6 is provided
with a projecting flange d (Fig. 1) or with an annular piece d (Fig. 2) which enables
the stopper to rest on the top edge of the neck so that a free space is left between
the bottom ring be of the stopper and the narrow part a¹ of the bottle neck a (Fig. 1)
or the partly blocked bottom end of the neck 4, (Fig. 2) which is sealed into the
interior of the neck a².
The closing device consists secondly, of a heavy clack-valve c of glass, porcelain,
earthenware or the like, provided with a long tail-piece c¹; with a truncated conical
head, c, ground so as to fit the narrow part of the neck, at the point 8, (Fig. 1) or to
the perforated end of the neck q (Fig. 2), and with a screw-threaded nipple c²
surmounting the head, this screw-threaded nipple affording means for folding, the
said clack valve, while being turned upon its seat s, in order to simultaneously grind
its head on to the said seat; and thirdly, of a spiral spring ", either conical or
cylindrical which bears against the lower part of the screw-threaded nipple c² being
connected to the lower thread thereof and extends in height over the whole chamber,
formed between the head of the clack valve and the bottom face of the rings 62. The
strength of the spring is adjusted to the weight of the clack valve, so that the
spring yields under the weight of the valve when the receptacle is reversed, but so
that it again returns the clack valve to its seat when the receptacle is placed in an
approximately horizontal position.
When the bottle « has been filled with the proper liquid, the clack valve c fitted
with its spring is inserted into its neck. After having covered the cylindrical part
outside of the stopper and of the ring or rings to be located in the interior of the neck,
with an adhesive material insoluble in water, the whole is bodily inserted and slightly
turned in its place. When the adhesive substance is dry, the stoppering of the
receptacle by ordinary means may be effected.
In order to empty the bottle, it is turned upside down, the clack valve then recedes
from the seat 8 compressing the spring r, and the liquid runs into the channel or
channels passing through the stopper and its rings. When the bottle is replaced
in its normal position, the clack valve is returned to its seat, under the action of the
spring.

page_text: 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 :-
A stopping or closing device for receptacles preventing their being refilled, formed
by the combination of a hollow stopper having an outer flange or projection d for
supporting the same upon the top edge of the neck of the receptacle, the said stopper
being internally provided with a diaphragm b", and being arranged adjacent to,
and sealed on to one or two rings 61 62, likewise provided with a diaphragm 6º,
the latter furnished with a flange 63, the stopper and rings being ground together
to fit the inside of the neck; of a heavy clack valve surmounted with a screw-threaded
head serving to hold the same during the operation of grinding the said valve on to
its seat, and of a spiral spring the strength of which is less than the weight of the
clack-valve.
