COMPLETE SPECIFICATION.
A New or Improved Stoppered Bottle.
I, JAMES GRIEVE LORRAIN, M. Inst. E.E., M.I.Mech.E. of Norfolk House, Norfolk
Street, Strand London, W.C. in the County of Middlesex, Chartered Patent Agent,
do hereby declare the nature of this invention (as communicated to me from abroad
by William Edward Forster, of 572 Essex Street, Lynn, Massachusetts, in the United
States of America, Gentleman) and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
The present invention relates to bottles and more particularly to a self sealing
bottle, and has for its object to provide a simple and inexpensive device to be secured
within the neck of the bottle to prevent the refilling thereof, so constructed and
arranged that upon the tipping of the bottle, the liquid which may be contained
therein can readily pour therefrom, but which when an attempt is made to refill the
bottle will instantly close the opening in the neck and prevent the entrance of liquid
therefrom.
To this end my invention embraces a self sealing bottle having in the neck portion,
a valve and valve seat, and a cam for automatically closing said valve.
It further embraces a self sealing bottle having in the neck portion a valve and
valve seat and a pivotted and swivelling cam for closing said valve; and it further
embraces the devices and combination of devices which will be hereinafter described
in the following specification and pointed out in the claims.
The invention is illustrated in the accompanying drawings in which
Figure 1 shows a central longitudinal section of a portion of a bottle, in an upright
position,
Figure 2 shows a similar view, the bottle being inverted,
Figure 3 shows a front elevation of the lock or seal removed from the bottle,
Figure 4 shows a side elevation of the guard,
Figure 5 shows a plan of the valve seat, and
Figures 6 and 7 show a modified form of the lock or seal.
In the drawing A represents the bottle, B the guard and C the lock or seal.
The bottle A is made of glass or any other suitable material and the neck thereof
is preferably formed with the enlargement a, the shoulder a¹ and the groove a², all
of which may be formed or pressed into the bottle during its manufacture.
As shown in the drawing the lock or seal c comprises the valve seat c and the valve c¹
and for the purpose of automatically closing the lock or seal I have devised the
following mechanism.
The valve seat c is preferably formed upon the flange c², of a short tubular body
portion c³, the flange resting upon the shoulder a¹ and being secured by cement or any
suitable packing in order to keep it in proper position in the neck of the bottle.
I have provided the valve seat c with a groove or depression c, and the valve c¹
with a soft facing of cork or any other suitable material, which will be compressed
and forced into the groove of the valve seat thus forming a positive closing of the
lock or seal.
For the purpose of forcing the valve against the valve seat and closing the lock or
seal I have provided the following mechanism.
Attached to, or formed integrally with the tubular body portion at its lower end
is a narrow cross bar c, in which is fixedly supported the stem or rod c', which supports
the closing cam cs, and upon which the valve c' is adapted to have a limited sliding

page_text: movement as shown, the valve being preferably provided with the short tubular
bearing c, which closely fits the stem or rod c. The closing cam cs, preferably
comprises the weighted body portion c, from which extends the cam section or
arms c, which are pivoted by screws or studs c12, to a freely swivelling collar or
block c, mounted upon the stem or rod c', and held from longitudinal movement on
said rod by the fixed collars or blocks c, held to said stem or rod by the set screws c".
The above suggested arrangement is such that when the bottle is in an upright
position the weighted cam will force the valve c¹ in close contact with the valve
seat c, thus sealing and locking the bottle and when the bottle is tipped, the weighted
cam will swing upon its pivots and move away from the valve c and permit the
liquid in the bottle to force it away from the valve seat and thus to permit a free flow
of the liquid from the bottle.
By mounting the came upon a swivelling support I prevent the possibility of its
getting in such a position that it may be held open, and the bottle filled by holding
it upon its side and submerging the same, for it is obvious that the weight will
swing by gravity to its lowest position thus forcing the cam section in contact
with the valve c¹ which will lock and seal the bottle.
It will be noted that the stem or rod e' is extended to form a bearing for the
weighted body portion of the cam c against which it rests when in its
inverted position, and which prevents its being swung completely over, and I find it
desirable to form a notch or bearing cle in the edge of the body portion c¹o, in which
the end of the stem or rod c7 fits when the bottle is inverted as shown in Fig. 2.
For the purpose of preventing the insertion of a wire or rod into the bottle to
tamper with the lock or seal C, I have provided a guard B fitted into the neck of the
bottle above the lock or seal C.
The guard B is made of glass, metal or other suitable material and comprises the
tubular portion b, of a diameter to substantially fit the inner diameter of the neck of
the bottle, and the bottom b¹.
The guard B is fitted within the neck of the bottle, and held therein with its top
substantially on a level with the top of the neck by any suitable means, as, by the
packing p, which may consist of cork, rubber or any suitable cement placed within
the groove a2 in the neck of the bottle and a groove 62 upon the outer side of
the guard B.
In the lower end of the tubular portion b of the guard B just above the bottom b',
there is formed a series of apertures &, through which the contents of the bottle may
freely flow.
Above the aperture & the tubular portion b is adapted to receive the usual cork or
stopper used in closing the bottle.
The guard B may be provided at its lower end with a rib or projection which is
approximately of the inner diameter of the neck of the bottle, and which is provided.
with a series of notches 6, whereby the liquid within the bottle may be permitted to
flow to and through the apertures b.
By the above suggested arrangement the liquid is permitted to have a free flow
from the bottle but no tool or wire can be inserted into the neck of the same to
tamper with the lock or seal.
In Figures 6 and 7 is shown a modification of the device wherein a small coiled
spring d is placed round the rod or stem c", which rests at one end against the fixed
collar cand at the other end bears upon the valve c¹, thereby holding the same in
close contact with the valve seat c.
For the purpose of withdrawing the valve from contact with the valve seat, the
cam is provided with the cam sections d in addition to the cam sections c", the
cam sections d'and c being oppositely disposed as shown, cam sections d being
opening cams and cam sections c¹ closing cams.
The valve c¹ is provided with the arms d, which have inwardly bent ends d³, which
take over the opening cam sections ; whereby a movement of the cam in one
direction will by means of the cam sections cl, force the valve in close contact with
the valve seat, and a movement of the cam c8 in the opposite direction will by means

page_text: of cam sections d' and arins d³, cause the valve c¹ to be moved away from valve seat c,
and permit the escape of liquid from the bottle.
It will be noted that by means of the pivoted weighted cam the lock or seal is
positively closed or locked, except when the bottle is inverted and that by swivelling
the support for the cam it will instantly fall into a closing position should the bottle
be held on its sides or in a horizontal position to attempt to fill it by submerging it.
Instead of forming the valve seat c upon the tubular section 3, I may form the
same on the shoulder a¹ in which case the rod or stem c² would be suspended from
the base of the guard B.
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 :-

valve, substantially as described.
