IMPROVEMENTS IN BOTTLES PROVIDED WITH INTERNAL STOPPERS
Year: 1884

page_text: I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN BOTTLES PROVIDED WITH INTERNAL
STOPPERS" 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 that class of bottles having internally grooved necks
and packing therein for use with globular stoppers, and means for controlling the
stopper within the bottle during the operation of pouring out the contents of the
same.
In the accompanying drawing.
Figure 1 represents an elevation partly in vertical section of a bottle embodying
this invention.
Figure 2 is an elevation of the bottle in an inverted position.
Figure 3 is a transverso section on the line x, x, figure 2.
Figure 4 is an elevation of the packing or seat of the stopper.
Figure 5 is a vertical section illustrating a modification.
A represents a bottle, and B represents a groove on the inner face of the neck
thereof, the said groove having two inclined faces a; the inclinations extending in
opposite directions and forming at their junction a ridge or projection a¹.
C represents an india-rubber bushing or packing which occupies the groove B,
and, as shown in figure 4, is of the shape of two frustums of hollow cones united
at their narrow ends, and of greater diameters than the groove B, so that the
packing requires to be compressed in order to be fitted in position, and when
located hugs the walls of the groove and tightly fills the same.
D represents a spherical or globular stopper, the diameter whereof is less than
the space within the ridge or projection of the groove, it being noticed that the
stopper is inserted in the bottle prior to location of the packing, the latter, when
located, reducing said space and producing a seat for the stopper, which latter, as is
evident, closes upwardly against the packing.
The bottle is filled and charged in any desirable manner, and the pressure within
the same holds the stopper firmly on the seat, producing an air-tight joint. When
the bottle is to be opened, the stopper is forced downwardly, thus overcoming the
internal pressure and causing it to leave its seat.
I am aware that it is not new to provide a bottle with a packing which is
primarily of cylindrical form, and which, when compressed, assumes the double
conical or inclined form of the groove; but this is only true to a limited extent,

page_text: for the upper and lower portions of the packing are liable to remain loose and slip
from position, thus-imperfectly holding the stopper.
In the present case, the exterior of the packing is primarily of the shape of the
groove, and when the packing is compressed and located, it expands and fully
occupies said groove and tightly rests therein, so that its upper and lower edges
abut against the upper and lower walls of the groove without being uncovered or
liable to uncover, and the packing is reliably restrained by the upper and lower
walls of the groove and prevented from slipping off when it is forced upwardly by
the stopper, acted upon by the internal pressure. The construction of the packing
also ensures a tight joint at all points between the packing and walls of the groove
whereby leakage thereat is prevented.
In figure 5 the groove and exterior of the packing are cylindrical, but the inner
face of the packing is inclined in opposite directions similarly to that shewn in
figure 1.
In either case however, the stopper makes a joint with the rise on the
inner periphery of the packing, thus keeping the contents of the bottle from
coming in contact with the packing, holding the packing in place, and preventing
the stopper from being forced out by pressure from within the bottle.
The side of the body of the bottle, near the bottom thereof, is pressed inwardly
at two places, as at 6 forming two internal shoulders E, which project towards
each other and flare from the place of starting of the depressions, as most clearly
seen in figure 3.
It will be seen that when the bottle is opened the stopper sinks to the bottom.
The bottle is then overturned or tilted, care being taken to place the part of the
bottle containing the depressions b on the under side, as shown in figure 2, whereby
the stopper abuts against the shoulders E, and is thereby held during the operation
of decanting or pouring out the fluid, leaving the neck entirely clear of the
stopper, it being seen that the stopper sents itself against the shoulders centrally in
the space between the same, the flaring or spreading form of the shoulders causing
said shoulders to present rising walls for the stopper while the bottle is tilted as
stated, whereby the stopper is prevented from leaving the shoulders even should it
rise to an extent greater than that shown in figure 2.
When the bottle is afterwards properly turned the stopper leaves the shoulders E
and may be directed to the packing of the neck for again closing the bottle, as is
evident.
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
First. A bottle having an internal packing for the neck thereof, consisting of an
annular piece of india-rubber or other suitable material, constructed of greater
diameter than the inner diameter of the neck, and having a rise on its inner
periphery, substantially as, and for the purpose, set forth.
Second. A bottle having two internal shoulders E formed in its side near the
bottom thereof, substantially as, and for the purpose, set forth.
Third. A bottle having on its exterior near the bottom, two depressions which
extend toward each other, forming two internal shoulders E which flare and
produce rising walls for holding the released stopper when the bottle is tilted,
substantially as, and for the purpose, set forth.
