"IMPROVEMENTS IN STOPPERS FOR PERFUMERY AND OTHER BOTTLES." (A com-
munication from abroad by Alphonse Allilaire and Louis Gerome, both of Paris,
France.)
This Invention refers especially to the stoppers of bottles for containing
perfumes but may be applied to other receivers, and offers advantages over those
now in use. Metallic stoppers of this kind generally have a tube passing through
the cork stopper which acts as a discharge pipe; it is on this tube the stopper
proper acts.
The latter is sometimes composed of a simple independent cap
loosely covering the tube; in other cases it is formed of an also independent screw
going into the tube; in these two arrangements the independent stopper is liable to
be lost. In other cases the screw is solid with a cap which is held by the edge of
a tube and cannot be completely detached from it, but then the liquid being held
in the cap at its point of exit from the tube can only run through apertures formed
at the upper part of the cap which is insufficient and inconvenient; besides in all
the previous arrangements the tube has an internal screw thread, and the liquid
rests in the threads and those of the nut, and the action becomes in time defective.
According to this Invention, on the contrary, the liquid exit tube communicating
with the interior of the vessel is quite satisfactory. The stoppage is obtained at
the upper part by means of a stopper fixed on a cap which may be raised or
lowered at will by means of a screw threaded nut or washer taking into a thread
forming the exterior of the tube.
The outflow tube is sunk in the ordinary way in the cork stopper; it is retained
by a capsule in form of a disc or annular plate which covers the cork stopper and
may be ornamented as fancy or taste may dictate. Above this plate the thickness
of the tube is increased, and it is provided with a screw thread on two diametrically
opposite points; this thread is cut longitudinally so as to form two recesses or
slide guides for the branches or legs of the cap which form the stopper. The
branches have at their lower or free end two lugs or flanges, between which there

the tube by the rotation of which the cap is caused to rise or fall. The top piece
of the latter is provided inside with a washer of leather or any other suitable
material which comes on to the upper orifice of the tube and thus forms the stopper
proper. This top piece being raised may be turned over or down; for this it is
only necessary to pivot the guiding branches of the cap. A modification only
differs from the other in dispensing with the washer nut; it is then the annular
capsule washer which is taken between the flanges of the branches and which is
provided with a screw thread taking into the thread of the tube in such manner as
to act as a nut and thus to cause the stopper to rise or fall. It should be understood
that the Invention is not to be limited to the precise details described; in fact, the
same may be modified according to the kind of stopper required, which may be
very varied. The form, size, and materials of which the stopper is composed may
be changed the number of the guiding branches of the cap; for example, there
may be a stop for the cap carrying the stopper hidden by an appropriate screw
arrangement.
