IMPROVEMENTS IN STOPPERS FOR BOTTLES
Year: 1884

PROVISIONAL SPECIFICATION.
I, MAX EMANUEL, of 1 Finsbury Pavement, in the County of Middlesex,
Merchant, do hereby declare the nature of my Invention for "IMPROVEMENTS IN
STOPPERS FOR BOTTLES" to be as follows:—
The object of my invention is to provide a Stopper which shall close automatically
and which may be opened by the pressure of a finger on a stud in such manner as
to allow a small quantity of the contents of the bottle to be ejected or thrown out
by giving the bottle a slight shake. Bottles fitted with stoppers according to my
invention are especially adapted for perfumes and some medicines, spirits, and other
fluids of which small quantities only are required at one time.
My Stopper consists of a double cap or top for the nose of the bottle consisting
of an upper and lower part with an intervening space, and these two parts may
either be made or joined together in one piece, or may be separate and fit together
with a screw. Through the lower or inner part of the double cap I provide a small
opening the size of which may vary according to the requirements of the particular
use to which it is intended to be put, and this opening is closed by a valve or cover
which is held or pressed against it by a spring or springs so as to prevent the
escape of the contents. This valve or cover which may be faced with cork or
India rubber I connect with a stud or lever projecting from the side of the cap in
such manner that when the finger is pressed on the stud or lever the valve or cover
is lifted and way made for some of the contents to escape into the space between
the upper and lower parts of the double cap. The upper part of the cap or
outer shell I pierce with one or more, generally 4 or 5 holes and from these the
contents of the bottle escapes, generally in many small drops, when the bottle is
shaken or in separate drops-one by one-when it is fitted for medicine and such
like fluids.
The moment the finger is removed from the end of the stud or lever the valve or
cover is brought by the action of the spring or springs against the opening in the
lower or inner part of the cap so as to close the opening, and the bottle is thus
automatically stoppered and the small quantity of fluid that may be between the
parts of or within the double cap having been shaken out no more can escape until
the stud or lever is again pressed. I prefer to attach the said cap or top: to the
bottle by means of an external or internal screw made on or in the neck of the
bottle and a corresponding screw in or upon the cap or top, but it may be attached
by means of cement or otherwise as most convenient.

I MAX EMANUEL, of 1 Finsbury Pavement, in the County of Middlesex,
Merchant, do hereby declare the nature of my Invention for "IMPROVEMENTS IN
STOPPERS FOR BOTTLES" 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 my invention is to provide a Stopper which shall close automatically
_ and which may be opened by the pressure of a finger on the end of a Stud or lever
_in such manner as to allow some of the contents-of-the-bottle_to_be_ejected or
thrown out when the Valve is thus opened; by giving-the-bottle-a-slight-shake.
Bottles fitted with Stoppers according to my invention are especially adapted for
perfumes and some medicines, spirits, and other fluids of which small quantities. are
required at one time, and may also be used for smelling salts, and for fine dry
_powders: My Stopper consists of. a double cap or top for the nose of the bottle,
consisting of an outer or upper, and an inner or lower part, with-an-intervening
space into which some of the contents of the bottle is allowed to pass when a Valve
is opened by pressure on a stud or lever, and from which it escapes by one or more
openings made for that purpose-in-the-upper-or-outer-part.of the Cap.
In the Drawings hereunto annexed and forming part of this my. Specification
I have shown at Fig. 1 a representation of one of my Stoppers attached to an
ornamental flask or bottle. Fig. 2. represents the Stopper in section. Fig 3.
:represents a modified form of the same, and Fig. 4. the various pieces soparately.
The drawings represent the form I generally construct, but it will be obvious
that the external shape, as well as some of the details of construction, admit of
considerable variation without departing from my invention.
In the drawings A represents the upper (or outer) and B the lower (or inner)
portion of the said double Cap, these two parts may either be permanently attached
to each other by the lower edge of the Cap A being bent over into a rim in the
part B as shewn in the Drawings, or may be separable and fitted together by a
Screw thread.
Through the lower or inner part B, of the double Cap I provide a small. opening d
the size of which may vary according to the requirements of the particular use to
which it is intended to be put. This opening is closed by a Valve e which I prefer
to face with Cork or India Rubber e¹, or which may be ground or otherwise fitted
on to its seat.
The Valve is pressed on to its seat by the spring f which may either be
spiral as shewn in the drawings, or of any other convenient shape. I operate the
Valve e either by a stem passing up through the top of the Cap A as shewn at a
in Figs 1 and 2 or by a lever arm g projecting from the side of the Cap A (Fig
shews both the stud a and the lever g, but these are alternative forms of construc-
tion and it is not to be understood that both are to be applied to one stopper) In
the former case I place the valve under the diaphragm forming part of the piece B
as shewn in Fig 2, in which the valve and stud are shewn separately under the
principal figure, or in the latter case I attach to the valve e an arm or lever
which projects through the side of the cap as shewn in Fig 1 and 3, which being
pressed down tilts or lifts the valve so as to open it slightly. The outer end of

page_text: the arm or lever g, I finish with a suitable knob or head which may be milled or
otherwise roughened to facilitate the pressure of it by the finger. By pressing the
stud a or the end of the lever g with the finger the valve is raised, and by inverting
and shaking the bottle a small quantity of the contents is passed into the space
between the two parts of the double cap, and thence escapes through one or more
small holes n, n, in the outer portion of the cap. These holes n n I make of size,
number, and position, to suit the requirements of each individual case, from two to
five small holes are generally sufficient.
I prefer to make the spiral or other spring of silver, or other metal which
is not easily corrodible, and for some purposes I prefer to attach the Valve e to the
part B by a joint instead of attaching it as shewn in the Drawings.
Instead of attaching the Stopper to the bottle by screwing it on to the outside of
the neck, I sometimes make the Stopper screw into a thread cut on the inside
of the neck, and in other cases instead of using a screw I attach the Stopper to
the inside or outside of the neck by means of Cement, or a Cork washer, or
otherwise, and in some cases I construct the nozzle of the bottle with a small
opening at the nozzle and make the valve seat itself directly on to the glass
without the intervention of the piece B which is not then required, but I make the
Cap A deeper and form in it a female thread (similar to that shown in the Drawings
in the piece B) and thereby screw the Cap A directly on to the bottle so that
the Valvo e scats itself directly on the glass nozzle and closes it-Sometimes
instead of contracting the nozzle of the bottle itself I insert into the neck a Cork
through which is a small tube on the upper end of which the Valve may close.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
Constructing Stoppers for bottles with a Cap or Stopper within which is a
Valve or Valves which may be opened by pressure on a stud or a lever or levers
and which when the stud or lover or levers are released is closed by a spring
substantially in the manner and for the purpose herein before described and
setfortli.
