Closing Device for Receptacles having Capillary Openings for the
Transport, Storage, and Use of Volatile Liquids.
I, CHARLES DENTON ABEL, of Birkbeck Bank Chambers, Southampton Build-
ings, in the County of London, Consulting Engineer and Chartered Patent Agent,
do hereby declare the nature of this invention (as communicated to me from
abroad by the Firm of Dr. Zimmermann, Lüthy & Co., Chem. Fabrik Brugg,
of Brugg, Aargau, Switzerland) and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
For several years past various devices have been invented having for their
object to effect the hermetic closure of glass or metal receptacles for, volatile
liquids having one or more capillary openings. Thus screw and bayonet like
closures and covers with spring action have been used; also a closure consist-
ing of a long caoutchouc band that was laid round the entire receptacle, and in
pressing upon the capillary opening, was supposed to effect the closure thereof.
This last named system has however not been found practical because it was
necessary to provide at the end of the receptacle opposite the capillary opening
a device for holding the band, which however did not afford the necessary
security for holding it in position. In addition the application of such a long
band was inconvenient for use because, not being permanently connected to the
receptacle it required a certain amount of practice to properly place it over the
opening again, after use.
This band device has however a decided advantage in that all use of metal,
and risk of formation of verdigris such as frequently occurs with brass closing
devices is avoided.
This invention relates to a closing device which allows in a very simple and
reliable manner, to effect a hermetic closure of a capillary opening without the
use of metal, by the employment of small short caoutchouc band which always
remains connected to the receptacle, and which can be easily manipulated by
every one.
I will describe the said device with reference to the accompanying drawing
in which Fig. 1 shews a form of the caoutchouc band detached; Figs. 2 and 3
shew vertical sections of two forms of the receptacle with capillary opening
having the said band in position for closing the capillary opening, while Fig. 4
shews the form of receptacle shewn at Fig. 2 with the caoutchouc band removed
from the capillary opening.
The glass capillary nozzle a of the receptacle (whether it be formed in one with
the receptacle, as would be the case if this were of glass, as shewn, or whether
the capillary nozzle be combined in any suitable manner with a metal receptacle)
has at a more or less short distance from the opening e, a knob-like swelling b
which may either be hollow as at Fig. 2, or be made solid as in Fig. 3, so that
here is no enlargement of the passage of the nozzle; this swelling has for its
bject to hold the ring shaped caoutchouc band i like the button and button

opening (not formed by a simple incision as the band would then be liable
to tear) which is passed over the swelling, so as to be retained behind it. The
closure of the capillary opening is now effected in an exceedingly simple and
quick manner by seizing the loop of the band and in stretching it, placing it
over the opening. When the receptacle is to be used, the opening is uncovered
by simply drawing the loop of the band i to one side so as to remove it from the
opening. The band thus remains attached to the receptacle both when this is
in or out of use, being retained behind the swelling but should it become defec-
tive it can readily be removed and replaced. by another one.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim
18:-
A closing device for a receptacle with capillary opening for containing volatile
liquids consisting of the combination of a ring shaped caoutchouc band having
a.button-hole opening, and a nozzle having a swelling or button at a short dis-
tance from its capillary opening the band being fitted with its button-hole over
the said swelling, and having its other part stretched over the capillary opening,
substantially as described.
