Improvements in the Stoppering of Flagons and Bottles.
I, HENRI CHOSSEFOIN, of 31, Rue Duret, Paris, France, Chemist, 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 invention relates to a new form of stopper for flagons and bottles which
is so constructed that when the stopper has been applied to any flagon, after such
flagon has been filled with any kind of liquid, such liquid may be poured out of
the flagon, either wholly or partially, but no new liquid can be introduced therein,
which has for result the guaranteeing of the genuineness of the original contents.
The system of stopper in question is produced by means of the combination of
four distinct parts, made of moulded glass, the union of which produces the
desired effect, as will be shown in the following description, reference being had
to the accompanying drawings, in which:
Fig. 1 is a vertical section of the neck of a flagon in which are arranged in
their respective places three parts 2, 3 and 4, which assist in effecting the object
of the invention...
The Figures 2, 3 and 4 are side elevations respectively of the parts 2, 3 and 4,
detached and shown separately.
The neck is at its upper part screw threaded interiorly at c.
This screw
thread corresponds to the thread of the screw of stopper 2. Beneath this
screw thread is a shoulder serving as the seat for the movable part 3, and again
further below is another shoulder y which serves as the seat for the movable
part 4, and which at the same time constitutes the inner entrance orifice of the
flagon 5.
The screw stopper 2 (Fig. 2) is of cylindrical form. It is pierced longitudinally
in its centre by a passage for the outflow of the liquid, terminating at its head
in a delivery spout e. The thread of screw is formed on the periphery to
correspond with the interior screw thread c of the neck 1. A crown or flange d
at the top of the said stopper 2 serves to regulate and limit its entrance within
the neck 1.
The part 3 (Fig. 3) which is also cylindrical is at its top made in the form of
a cup f; on its outer surface it is formed with vertical webs which project
slightly above the top, and at the bottom it terminates in a downwardly extending
tail .
The part 4 (Fig. 4) is composed of a head j in the form of a cup, and of a
tail k. Between these two parts a circular groove, in which may be placed,
if desired, a rubber ring or washer 1.
The method of employment of these different parts is shown in Fig. 1 of the
drawing, and is as follows:
The flagon 5 having been filled with any liquid, within the neck 1 is first
introduced the part 4, the head of which is arrested at the orifice y, which it
closes, the tail extending downwards into the interior of the said flagon. Above
in its turn is introduced the part 3, the head f of which then rests upon the

page_text: shoulder, whilst its tail h enters freely into the cup j of the part 4; and
finally, above the whole, into the neck 1 is screwed the stopper 2, the outside of
which has been coated with any gum or insoluble composition.
Under these circumstances the enclosed liquid may at any desired moment be
poured out either wholly or partially, in a single or several operations, by
inclining the flagon 5 at a sufficient angle to enable the two parts 3 and 4 to be
respectively raised and moved from their seats. But the partial or complete
pouring out of the original liquid having taken place, no fresh liquid can be
introduced, the movable parts 3 and 4 having by reason of their weight auto-
matically resumed their positions on their respective seats, as
soon as the
inclination imparted thereto is removed, forming by their combined action a
complete obstruction to the fresh entrance of any kind of liquid. Further, no
manipulation having for its object to raise them from their seat can succeed,
the stopper 2 not being capable of being removed, and the parts 3 and 4 by the
combined action preventing any operation of this kind.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. In the flagon 5, the arrangement of a neck 1 screw threaded at its upper
part, having below a shoulder a, and a restricted orifice y forming the interior
entrance to the said flagon 5, substantially as and for the purpose specified.
2. A screw threaded stopper 2 perforated longitudinally at its centre, with a
delivery spout, a movable part 3, with a cup at the top, webs and a downwardly
extending tail, and another movable part 4 with a cup at the top and downwardly
extending tail, which effect the closing of the interior orifice of the flagon 5.
with or without the aid of an india rubber washer, substantially as and for the
purpose specified.
