DIECITIVATION.
Improvements in and relating to Bottles and like Receptacles for
Containing Perfumes.
We, BRUNO HENNIG of 12 IV Uhlandstrasse Mechanic, and MAX JAHN of
17 Grossenhainerstrasse Merchant, both of Dresden in the Kingdom of Saxony
and German Empire, 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 bottles and like receptacles for containing perfumes, and
its object is to provide means by which the contained perfume may be expelled and
if desired be spread or be formed into a spray.
In the receptacles as ordinarily formed, the perfume is expelled by the pressure
of air forced in by an indiarubber ball. The disadvantages of this system are
that the ball has to be pressed every time any of the perfume is required, that
impure air is often forced into contact with the liquid, and that evaporation takes
place when the pressure is removed during the time no liquid is being forced
from the bottle.
In a bottle constructed according to this invention, all these objections are
overcome by the introduction into the bottle of a gas at a pressure sufficient to
expel the whole of the contents when a free outlet is provided.
The accompanying drawings, reference to which is hereinafter made, illustrate
in what manner this invention may be carried into effect.
Figure 1 is an illustration of a vertical section of a bottle constructed to embody
these improvements.
Figure 2 represents an elevation of a similar bottle.
The neck of the bottle has screwed into it a suitable cap or casing a, an air tight
connection being ensured by the packing washer b. A screwed ferrule c is formed
upon and communicates with the cap a, the communicating channel e being
controlled by the back pressure valve f. A screw cap or plug d closes the
channel e. The delivery tube 9 extends to nearly the bottom of the bottle and
terminates at its upper end in the side of the cap a opposite to the spreading or
spraying outlet i which is closed by a valve h.
In order to introduce the compressed gas, the cap d is removed and the ferrule c
is connected to a suitable gas supply. The gas enters the bottle through the
valve which is closed by the pressure within the bottle when the pressure from
the gas supply is removed or reduced. The channel is then securely closed by the
When it is desired to obtain some of the perfume, the valve h is opened by
pressure of the finger and the liquid is expelled from the bottle by the pressure
of the contained gas. The valve must of course be provided with a returning
spring of a sufficient strength to overcome the pressure of the gas.

Any suitable gas may be employed which is not injurious to the perfume but we
prefer to employ carbonic acid gas.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
In a bottle or like receptacle for containing perfumes under pressure, the
combination with a back pressure gas inlet valve of a spreading or spraying mouth-
