Improvements in or relating to Liquid, Powder, and like Receptacles
and Distributors.
A communication from OSKAR GEORG ERNST URBAN, Merchant, of Schloss-
strasse 18, Dresden-A, Empire of Germany.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of London,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The present invention relates to a liquid, powder or like receptacle with an
adjustable stopper, which is loosely or movably arranged on a guiding device
so that it can move freely between its seat and an adjustable abutment, in such
a manner that the stopper will fall to its seat when the receptacle is in an upright
position, while when the latter is partly inverted or turned upside down it will
move forward leaving an opening between it and the edge of the neck or open-
ing of the receptacle through which the contents will be discharged. By this
automatic arrangement of the stoppering device the receptacle in question is
superior to those of older construction which are provided with a valve at the
bottom which is opened by a pin when the latter is pressed down. Receptacles
of this kind suffer from the drawback that the contents will fall out should the
valve happen not to close tightly; and this applies both to liquids and powders.
Other receptacles with sieve-like covers admit air to the contents, which, there-
fore, are liable to take up dust and disease germs or dampness, or decrease in
quality or quantity through evaporation. The present receptacle is, on the
contrary, so arranged that it can be hermetically closed when not required for
use. The sieve perforations in the distributing devices of older construction are
easily stopped up and otherwise inconvenient and besides the quantities used
are not easily controlled.
The new receptacle is well adapted, owing to the evenness of distribution and
the possibility of allowing small quantities to issue by correspondingly adjusting
the width of the discharging opening, for the purpose of measuring doses or
chemicals and medical substances. In this case the arrangement according to
which the vessel closes itself automatically when placed in a normal or upright
position is of great importance, especially when the contents are of a volatile
nature.
In the accompanying drawings several modifications of construction of the
receptacle are represented, differing from each other in the form and construc-
tion of the stopper and in the means by which the guiding of the stopper is
caried out. But all these different forms of construction have a common feature
which has not been before mentioned, namely, that the stopper may be tightly

page_text: and permanently fixed on its seat. This is of great importance especially in
cases when filled receptacles are packed for transmission, or are intended to
remain closed for some time.
In all the figures the body of the box is marked by the letter A. Its opening,
upper edge or neck is so constructed as to form a seat in which the stopper
exactly fits.
According to Figure 1 (longitudinal section) the seat a of the receptacle A is
shaped like a hollow cone. The stopper B, is similarly shaped and fits into it,
and is movably mounted on a pin c. This pin is secured to the bottom of the
receptacle and is provided at its upper end with a screw-thread to receive a nut c¹,
by means of which the displacement of the stopper B from its seat is limited,
and by means of which the stopper B may also be forcibly held against its seat a.
Whenever the receptacle is partly inverted or turned upside down, the stopper B
will move into the position indicated by the dotted lines, leaving an annular
space between a and b through which the contents of the receptacle can pass.
Whenever the latter is returned to its normal position the stopper B will auto-
matically fall back on its seat a, and if in this position the nut c is screwed down,
the receptacle becomes permanently closed.
According to Figure 2 (longitudinal section) the conical stopper B is provided
with a bore or recess b (which does not pass through it entirely) to allow the
stopper to be guided on the pin c². This pin is adjustably mounted in the bow
or handle c³, and can also be screwed down so that the stopper B is tightly pressed
against its seat a. The space between the bottom of the recess b and the end of
the pin 2 determines the extent of opening of the vessel.
In all other figures the stopper is shown, for the sake of clearness, in the open
position, although the receptacles are represented as standing upright.
According to Figure 3 (longitudinal section on the line 3-3 of Figure 4) and
Figure 4 (plan) the conical stopper B is provided with an upward projection
or boss b¹. This projection fits into a socket or cap d which is held in position
by two arms d', and connected with a ring d². The ring d³ can be screwed on to
a ring a which embraces at the edge the seat or the neck a of the receptacle.
The guiding of the stopper is effected by the movement of the projection 6¹ in
the cap d and by the adjustment of the parts d d d the width of the opening
can be adjusted. By screwing down the device d d the stopper B is tightly
pressed against the seat a.
According to Figure 5 (longitudinal section on line 5-5 of Figure 6) and
Figure 6 (plan) the conical stopper B is provided with a depression or recess
into which fits a ring plate e, connected to arms d' attached to a ring d² screwed
on the outside of the receptacle. By means of this arrangement the stopper is
guided in a similar way as in the case of the construction represented in Figure 2.
The edge or flange e¹ of the plate e limits the opening space. The receptacle is
shown in the present construction as a cylinder from the upper edge of which
the seat a projects inwardly towards the centre. The hollow conical part a
passes from the narrowest part of the seat back to the wall of the vessel and thus
forms an angular chamber a³ between the seat and the wall of the vessel.
be a cone.
A further modification is represented in Figure 7, in a longitudinal section on
the line 77 of Figure 9, Figure 8 being a detail view and Figure 9 a plan.
This construction shows that it is not absolutely necessary that the stopper should
The stopper is represented here as a disc B¹, and the seat by an edge
or flange a. The adjustment is effected by the vertical parts of the arms d¹
which hold the edge of the disc B'. These arms are, in the same manner as in
the construction according to Figures 3-6, connected with a ring d³ which
screws on to the part a¹ of the receptacle. The upper parts of the arms how-
ever are fixedly connected with a disc f which limits the opening through which
the contents may be discharged and by means of which the disc B¹ is pressed on
its seat a when the ring is screwed down. The contents of such a receptacle
find an exit between the disc B¹ and top at when the box is turned upside down.

page_text: Finally, a construction is represented in Figure 10 in longitudinal section in
which a flat stopper B² is combined with a hollow cylinder or flange b³ fitting into
the neck a of the receptacle A, by means of which arrangement the movement
of the stopper is guided. The hollow cylinder 63 is provided close underneath
the disc portion B2 with a number of perforations 6 through which the contents
of the receptacle issue when the stopper moves forward on the box being turned
upside down. Closing is effected by pressing down by means of the screw c the
disc B2 on to its flat seat arranged on the neck of the receptacle. The width
of the opening is adjusted here in the same manner as in the construction repre-
sented by Figure 2, by means of the adjusting screw and c. The disc B³ is
also provided on its interior end within the hollow cylinder 63, with a cone 65 for
guiding the contents of the receptacle towards the perforations 64 of the cylinder
whenever it is turned upside down.
It will be evident that various other modifications of constructions may be
made without departing from the characteristic features of the invention.
