Improvements in Bottle-stoppering Devices.
A communication from MAX ELB and F. G. MOSER, of Dresden, in the Empire of
Germany.
I, ALFRED JULIUS BOULT M.I.M.E., of 323 High Holborn in the County of
Middlesex, do hereby declare the nature of this invention and in what manner the
same is to he performed, to be particularly described and ascertained in and by the
following statement :-
This invention consists in a device for stoppering or closing bottles and other vessels,
so constructed that when it is inserted into the neck of the bottle or the like to its
full extent it entirely closes the outlet, being retained in this position by means of
two bent pieces engaging in two grooves formed externally on either side of the neck;
while when it is slightly raised, though not entirely removed from the bottle, it opens
more or less two lateral orifices or passages, through either of which the liquid can
escape, while the other admits the external air.
This device is especially valuable where it is desired to pour out small quantities of
liquids such as medicine, scent, acids, ink, and gaseous liquids.
In the accompanying drawings,
Figure 1 represents the neck of a bottle with the stopper fully inserted and closing
the two side-passages provided in the neck.
Figure is a longitudinal section of Fig. 1.
Figure 3 is a cross-section taken on a line below the outlet orifices.
Figure
4 is a plan of a bottle-neck provided with channels and
Figure 5 is a longitudinal section thereof with the stopper inserted.
Figure 6 is a cross-section, and
Figure 7 is a longitudinal section thereof with the stopper raised.
Figure 8 is a longitudinal section of a bottle-neck provided with lateral orifices
and in which the stopper is raised.
The neck of the bottle a to which this improved stoppering device is to be applied
may either be provided with two lateral orifices c, the lower edge of which assumes
the shape of a lip d (see b, Figs. 1 and 8) or it may be formed with two grooves or
channels e (see Figs. 4 to 7). The stoppering device consists of a cap f provided
at each side with an arın or clamp g the ends h of which arms are turned in somewhat
like hooks. Within the cap f is secured a stopper of cork, wood, india-rubber or
equivalent material by means of a pin or screw k. This stopper is of such length
that when it is inserted into the bottle-neck to its full extent, it projects beyond the
lateral opening c or channels e as the case may be.
In the latter arrangement the
cap should be provided internally with a pad or packing m. The hook shaped ends
of the arms genter respectively the vertical grooves n provided one on each side of
the neck of the botile, and terminating, each at its lower end in a horizontal groove n¹.
In these horizontal grooves are held the books / so long as the bottle remains closed,
so that the stopper is prevented from rising spontaneously. When it is desired to
open the bottle the stopper-device is raised sufficiently to enable the stopper proper to
take up its position over the side openings c of the neck of the bottle, or so as to open
a portion of the channels e, as the case may be. The stopper need not be removed
from the neck of the bottle all that is required to, pour out the contents of the latter
being a suitable adjustment of the outlet openings by raising the stopper more or
less and thereby creating a larger or smaller free passage through the openings c or
channels e. Where openings such as c or grooves such as e are used there should be
two of each in the bottle-neck so that one may serve as an outlet while the other
admits air into the bottle.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondents, and in what manner the
same is to be performed, I declare that what I claim is :-
1. A stoppering device for bottles and the like comprising lateral orifices such as c
or channels such as e in the vessel and a stopper 7 to close them substantially as
described and illustrated in the accompanying drawings.
2. In stoppering devices for bottles and the like the combination with a resilient
stopper such as l of a cap such as fa pin or screw k and clamps such as g the ends h
of which are turned inwards or hook-shaped substantially as described and illustrated
in the accompanying drawings.
