STOPPERS FOR BOTTLES."
"IMPROVEMENTS IN
This Invention relates to internal stoppers for bottles containing gaseous or
aerated liquids, and consists of a hollow conical or bell-shaped plug composed of
glass, wood, ebonite, or other suitable material, and provided with a ring of india-
rubber or other suitable yielding material which fits into a recess on the exterior
of the stopper.
When the stopper fitted with the elastic ring is forced into the neck of the bottle
by the pressure of the confined gas leakage is effectually prevented.

IMPROVEMENTS IN

page_text: glass, wood, ebonite, earthenware, non-corrosive metal, or other suitable rigid
material, and provided with a ring of india-rubber or other suitable elastic or
yielding substance which fits into an annular groove or recess on the external
periphery of the plug.
The stopper when in the bottle is arranged with its larger end downwards 50
that on being forced by the pressure of the confined gas into the neck of the bottle
(which is made of a suitable shape to correspond to the shape of the stopper)
the elastic or yielding ring is compressed between the stopper and the internal
sides of the neck of the bottle and leakage is effectually prevented.
The accompanying Drawing represents a vertical section of a portion of a bottle
fitted with a stopper constructed according to my said Invention.
A is a hollow conical plug of rigid material (such for example as glass, wood, or
earthenware) inserted base downwards in the bottle B and provided on its external
periphery at a with an annular groove or recess in which is fitted a ring C of india-
rubber or other suitable elastic or yielding material.
The neck b of the bottle is made of a taper form on its interior, approximating
to the shape of the sides of the stopper as shewn in the Drawing, so that the stopper
and bottle are adapted the one to the other.
In the application of my improved stopper when the stopper is forced into the
neck of the bottle by the pressure of the confined gas the ring C is compressed
between the plug A and the taper sides of the bottle neck b and a perfectly gas-
tight joint is obtained.
:―
By the use of my said Invention the following advantages are secured, videlicit :-
Lightness in the stopper due to its hollow form, cleanliness in its use by reason of
the small amount of surface of the elastic ring exposed to contact with the liquid,
and efficiency in the tightness of joint maintained as a result of the large superficial
area subjected to the action of the gas.
The bottle can be opened simply by the pressure of the hand, the stopper when
completely tightened being in such a position that its solid end protrudes to a sinall
extent beyond the mouth of the bottle, whilst at the same time its lower portion is
concealed from view. Owing moreover to the lightness of the stopper it creates so
little disturbance in falling on the bottle being opened that no escape in the form
of spray takes place, and as the stopper by reason of its shape does not cause any
obstruction to the effluent liquid during its descent a considerable saving is effected
in the time necessary for discharging the contents of the bottle.
Having now described and particularly ascertained the nature of the said
Invention, and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion that what I consider to be novel and original,
and therefore claim as the Invention secured to me by the herein-before in part
recited Letters Patent is, a stopper consisting of a hollow conical or bell-shaped plug
employed base downwards and having on its external periphery an annular groove
or recess in which is fitted a ring of elastic or yielding material, the stopper being
constructed, arranged, and applied substantially in the manner herein-before
described.
In witness whereof, I, the said George Belleini, have to this my Specification
set my hand and scal, this Twenty-first day of January, One thousand eight
