We, THOMAS SUTCLIFFE, of Barnsley, in the County of York, and
JOHN FEWINGS, of Bridport, in the County of Dorset, do hereby declare.
the nature of our said Invention for "IMPROVEMENTS IN THE CONSTRUCTION
OF BOTTLES AND THEIR STOPPERS FOR CONTAINING AERATED LIQUIDS," to be as
follows:-
The Invention relates,-
Firstly. To the construction and manufacture of that class of bottle
for containing aerated liquids in which the outlet or orifice is closed by
an internal stopper forced against the rim or contracted portion of the
neck by the pressure of the escaping gas.
And, Secondly. To the novel construction of the internal stopper
itself.
The difficulty hitherto experienced in bottles designed for containing
liquids having internal stoppers is the tendency such internal stopper
has to retard and prevent the free flow of the liquid at the time of

page_text: pouring the same from the bottle by reason of the stopper entering and
resting in the orifice. To obviate this difficulty is the object of the first
part of the present Invention, the novelty of which consists in providing
the bottle with an indented annular ring or recess at any portion of its
external surface between its base and neck, which annular indentation
contracts the internal capacity of the bottle at the point where it is
made, and so forms either an external or internal swell or ledge on
which the stopper rests when pouring the liquid from the bottle, thus
preventing the stopper entering the orifice so as to impede the flow of
Or in lieu of an annular external recess such recess may be
formed internally, in which case an internal groove or channel would be
formed, which in like manner would catch the stopper and so allow of
the free flow of liquor from the bottle. This ridge is made by an
ordinary pair of bottle tools, such as are used for soda water or beer
bottles.
the same.
Secondly. The improved construction of stopper is designed for the
purpose of enabling the same when being forced into the orifice by the
pressure of gas to fit in the neck of the bottle, and hermetically close
the same, regardless as to which of the ends first entered. In order to
secure this object I first form à bobbin-shaped stopper of glass or other
suitable material, the flanges of which are somewhat less in diameter
than the orifice of the bottle formed by the shoulder in the internal
construction of the neck. The body of this stopper between its flanges
is barrel-shaped or convex, around which when the stopper is in the
bottle an india-rubber tube is forced so as to occupy the space between
the flanges, and so form a yielding swell somewhat larger than the
internal orifice of the neck, so that when forced by pressure of gas
against such orifice it hermetically closes the bottle. One of the novel
features of this stopper being that whichever end thereof happens to rise
against the orifice of the neck whilst pouring the contents therefrom it is
equally effective.
