Improvements in Self-sealing Bottles and the like.
We, HENRY PITT ROBERTS, of 133 West Newton Street, Machinist and
WILLIAM HAYES, of 22 Cambridge Street, Merchant, hoth of Boston, in the
County of Suffolk, State of Massachusetts, United States of America, 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 :-
Our invention relates especially to that class of bottles which are known as
self-sealing, the object being particularly to prevent refilling of bottles or similar
liquid receptacles with an inferior quality of liquors after having been emptied of
their original contents.
In the accompanying drawing,
Figure 1 is a vertical transverse section showing the neck of our improved
bottle;
Figure 2 is a horizontal section taken on line ce in Figure 1.
Figure 3 a like view taken on line y, y in Figure 1.
Figure 4 a vertical section showing the preferred form of valve and bottle neck.
Figure 5 a horizontal section on line zin Figure 4, and
Figure 6 a like view taken on line », r, of Figure 4.
Like letters and figures of reference indicate corresponding parts in the different
figures of the drawings.
...
A represents the neck of the bottle which is represented as broken off. Said
neck has a bulb C, blown in its walls forming a chamber B an appreciable distance
from its mouth. The bottom of said chamber at d, where it joins the body of the
bottle forms a valve-seat upon which a cup-shaped valve D, rests.
g
The valve-face is semispherical and extended into a tubular body fits mouth
being open.
The bottle around its mouth is provided with the usual annular
flange. The wall of the mouth of the bottle has an annular shoulder or
rabbet i.
A hollow stopper H has an annular flange which rests on the shoulder i,
Said
said stopper projecting inward with its inner end in the chamber B.
inner end is conical at and the parts are so arranged that when the bottle
is in vertical position said conical end projects into the mouth g of the valve D.
Above the conical end k of the hollow stopple one or more openings m are formed
in said stopple through which the liquor may pass from the chamber B.
..In Figure 1 the valve is a ball which engages the seat and the stopple H is
cemented into the mouth of the neck. More openings m, are employed in this form
than in that first described.
j
We find that by securing the flanged end of the stopple into the rabbet i at
the mouth of the bottle neck by cement or similar means the liquor is caused to
corrode. To overcome this we supply a locking or fastening cap b, which overlaps
P the flanged edge of the stopple and then is turned downward over the flange h,
of the bottle-neck and reamed at y, thereunder by any suitable device. The
centre of the cap coinciding with the mouth of the stopple, h, is open at t to receive
a cork stopper whereby the bottle may be closed in the usual manner.
at
In the use of our improved bottle, the bottle is first filled, the hollow cup-shaped
valve D, is then dropped on to the seat and the hollow stopple H is inserted
in the mouth of the bottle and is pendent from the rabbet i.
The metallic locking cap bis then adjusted securing the hollow stopple in
position after which the bottle is corked in the usual manner.

page_text: When the bottle is inverted the cup-valve D, falls against the conical. end k of
the hollow stopple its circular mouth playing around said end affording practically
a universal movement to the valve which remains seated in all inclined positions
while the body of the bottle is below a horizontal plane rendering it necessary to
practically invert the bottle before the cup valve will entirely leave its seat and
permit the flow of the liquid around it through the openings me and out of the
hollow stopple.
•
By this arrangement of parts it is practically impossible to refill the bottle
without breaking or destroying either the valve or the hollow stopplé.
The form shown in Figure 1 is practically the same as that shown in Figure 4,
but to obviate all chance of raising the valve and refilling the bottle we preferably
employ the cup-valve.
Liquid inserted in the stopple will pass through the opening m and running
down the conical apex will fill the valve D driving it against its seat d. The parts
are so arranged that the valve cannot interfere with the openings m while
discharging the liquid from the bottle.
The valve-seat in the preferred form is at the junction of the neck and body of
the bottle as it is easier to construct than to form a projection into the neck of the
bottle as in Figure 1.
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 :-
:-
1st. A bottle or similar liquid receptacle provided interiorly of its neck with
a valve-seat; a loose cup-shaped valve on said seat; and a hollow stopple secured
in the neck and projecting into the mouth of said valve, substantially as
described.
2nd. A bottle or similar liquid receptacle provided interiorly of its neck with
a valve-seat; a loose cup-shaped valve on said seat; a hollow stopple secured in
said neck and having a conical end projecting into said valve; and one or more
openings in its side wall, substantially as and for the purpose set forth.
3rd. A bottle or similar liquid receptacle provided interiorly of its neck with
a valve-seat; a loose valve on said seat; a hollow stopple in the mouth of said
neck having a closed inner end and one or more perforations in its side wall
and a metallic cap overlapping the outer end of said stopple and secured to the
outer face of the neck.
4th. In a bottle or similar liquid receptacle, the neck A in combination with the
hollow stopple H, therein and the cap B secured to said neck and overlapping said
stopple.
5th. In a bottle or similar liquid receptacle the neck provided with the valve-
seat in combination with the cup-valve D and the approximately conical hollow
stopple secured in said neck and projecting into said valve, said stopple being
provided with one or more openings m.
6th. In a bottle or similar liquid receptacle an interiorly flanged neck in
combination with a hollow stopple; and a metallic locking cap overlapping said
stopple and secured under said flange, said cap having an opening coinciding with
the stopple mouth.
7th. A bottle or similar liquid receptacle provided interiorly of its neck with
a valve-seat; a loose valve on said seat; and a hollow approximately conical
stopple secured in the mouth of the bottle and provided with one or more openings
in its side wall.
