An Improved Inhaler,
THE ANGLO-SWEDISH TRADING ASSN. LTD. 64, Aldersgate Street, London, EC.
and GUSTAF OTTO RENNERFELT, Engineer, of "18, Fredsgatan, Stockholm, Sweden,
do hereby declare the nature of this invention to be as, follows:
Our improvement consists in so constructing the inhaler that when in use-the..
atmospheric air is prevented from entering the nostrils. until it, has first, become
impregnated with: the inhalation matter, by passing through it..
This we effect in the following manner, but we do not restrict ourselves to the
specific means adopted :-
-
To a bottle or other vessel of suitable size and form, we apply a bifurcated
projection (which may be an integral part of the main body) having one or more
openings or holes communicating with the interior of the vessel, the said bifurcated
projection sbeing so formed and its hole. or, boles, so situated as,to,, when applied
to the nose, prevent inhalation except through the said holes..
The inhalation matter, snch. as menthol, or other, suitable material, is contained
in the body of the, said.;vessel.which, is provided, with one or, more perforated.or
porous plugs or stoppers,, which serve the double purpose of enabling the inhaler
to be charged and when in place allow the admission of air to replace that withdrawn.
by inhalation.
1, may perforate other. parts of the inhaler instead of, or. as: well as the stopper,.
the main object being to so place these admission air holes as to constrain the air to
pass through the inhalation matter before, reaching, the emission hole or:holes.

GUSTAF OTTO
RENNERFELT, Engineer, both of 64. Aldersgate Street, London, EC... 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::-
The object of this invention is to provide an inhaler that will serve the
itris intended for more. efficiently-and-economically than those commonly in use,
which, while being used, allow a large proportion of the inhalation matter, to
into the air and be wasted, while that which is inhaled. is, considerably diluted by
its-admixture, with the air which is unavoidably inhaled when the. nose is placed
over the open mouth of a bottle or other containing, vessel...

Our-improvement consists innso constructing the inhaler that.when in use..the
atmospheric air, is. prevented from entering the nostrils. until it has, first. become
impregnated with the inhalation matter by passing through it.

page_text: This we effect in the following manner :-
To a bottle or other vessel of suitable size and form we apply a bifurcated
projection (which may be an integral part of the main body) having one or more
openings or holes communicating with the interior of the vessel, the said bifurcated
projection being so formed and its hole or holes so situated as to, when applied to
the nose, prevent inhalation except through the said hole or holes.
The inhalation matter, which may be menthol, or may consist of any suitable
absorbent material such as sugar saturated with aromatic salts or any other suitable
drug, is contained in the body of the said vessel which is provided with one or
more perforated or porous plugs or stoppers which when in place serve the purpose
of confining the inhalation matter, while allowing air to pass through them to
replace that withdrawn by inhalation.
In some cases we may perforate other parts of the inhaler instead of or as well
as the plug the main object being to so place the air admission hole as to constrain
the air to pass through the inhalation matter before reaching the emission hole
or holes.
In the accompanying drawings :―
Fig. 1. is a top view and vertical section of one form of my invention, the plane of
section being indicated by a broken line in the top view.
Fig. 2 is a top view and similar vertical section of a part of a modified form of
inhaler.
Fig. 3 is a top view and similar vertical section of a part of another modified
form of my invention, and
Figs. 4, 5 & 6 are respectively a vertical section on the line x-x in Fig. 6, an
end view and a plan of a further modification.
In each of the figs. A represents the body of the inhaler in which the inhalation
matter B is retained by the perforated plugs "a" which are kept in their
respective places by any suitable means such as plaster of Paris or they may be
removable.
A is a hollow bifurcated projection, which may form an integral part of the
body A, or might be inserted like a stopper (not illustrated,) and has one or more
holes a¹.
In use, the inhaler shown in Fig. 1 is applied to the nose so that the horns a³
enter the nostrils, while with that shown in Figs. 2 & 3 the nose is placed between the
horns a².
In Figs. 4, 5 & 6 the bifurcated projection is applied to the side of the vessel,
instead of at one of the ends, and has air admission holes as formed in the body A
of the inhaler at one end and a perforated plug a at the other, but in some cases
we may use a perforated plug at both ends, or we may make both ends as at A'
and insert the bifurcated part Å¹ in a suitable hole like a stopper (not illustrated).
The inhalation matter may be prevented from falling through the holes a¹ by
plugging the bifurcated part A' or the horns a' with any suitable porous material b
(see Fig. 4.).
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. An inhaler consisting of a suitable body or containing vessel, in which the
inhalation matter is retained by one or more removable porous or perforated plugs, and
having a hollow bifurcated projection provided with one or more holes substantially
as described & for the purposes set forth in the specification.
2. An inhaler consisting of a suitable body or vessel, to contain the inhalation
matter, having perforations at one or more of its extremities and a suitable neck
or hole, substantially equidistant from the said extremities, adapted to receive a
hollow bifurcated part containing one or more holes substantially as described and for
the purposes set forth in the specification.

as described with reference to Fig. 1.
4. The combination and arrangement of parts constituting an inhaler substantially
as described with reference to Fig. 2.
5. The combination and arrangement of parts constituting an inhaler substantially as.
described with reference to Fig. 3.
6. The combination and arrangement of parts constituting an inhaler substantially
as described with reference to Figs. 4, 5 & 6.
