LAUCHLAN ROSE, of Curtain Road, Finsbury, in the County of Middlesex. "IM-
PROVEMENTS IN BOTTLES AND STOPPERS FOR AËRATED OR EFFERVESCING BEVERAGES
AND LIQUIDS."
The difficulty hitherto experienced in the use of inside stoppers for aërated waters
has been the tendency of such stoppers in discharging the liquid to fall into the
neck of the bottle, thus preventing its free outflow. This difficulty has already
been tried to be obviated by forming recesses in the neck and other parts of the
bottle, into which the stopper falls on being pressed from its seat, thus allowing
free discharge of its contents. The great objection to such forms of bottles, however,
is the weakness it produces at the recessed portion of the bottle, and consequent
large percentage of breakage in filling, washing, and so forth.
My improved form of bottle consists of a recess formed at or about the middle or
bottom of the bottle, combined with a conc-like projection inside, and rising from
the bottom of the bottle, so that when the stopper is pressed from its seat in the
neck of the bottle it will fall upon the cone, and rolling down its sides be thrown
into the recess thus formed, and be retained in this position during discharge of the
contents.
This form of recess for receiving the stopper in discharging the contents of bottle
is suitable for beverages of high gas pressure, such as soda, potash, and other
aerated waters, and by spreading or dividing the metal more regularly over the
mould in the process of making the bottle it is strengthened throughout, and is
thus superior to any other form of bottle for aërated waters in use for inside
stoppers.
Another form of bottle, suitable for aërated beverages of low gas pressure, such
as lemonade and other syrup drinks, I produce by elongating the neck inside and
past the shoulder of the bottle, forming a recess at this part of the bottle in which
the stopper is retained in process of decanting. In this case I dispense with the
coned bottom, necessary in the form of bottle first described. In both forms of
bottle I make a ledge as a seat for the stopper in the neck of the bottle, either by
contraction of the mould at place required, or by tools suitable for the purpose, in
forming the head of the bottle. I also form an indented ring on the outside head
of the bottle in any place from a little below the lip of the bottle, such indented

marked on it the name of the beverage, thus dispensing with labels as well as
protecting the bottle mouth from dust and such like to which all bottles stoppered
from inside are exposed, and which hitherto has formed a great objection to their
more general use.
My improved stopper may be made of wood, earthenware, or other suitable
material. Its form consists of a double cone, attached at bases, and forming the
middle portion of the stopper, with heads or ends at the smaller ends of the cones.
The body or cone portion I form with several indented rings, and the heads or ends
with V shaped recesses. Round the centre or cone portion of the stopper a tube of
rubber or other elastic material is placed, which is effectually held in its position by
the indented rings and recesses already described, by which means the stopper thus
completed can be forced into the bottle ready for use, thus overcoming the objection
of providing reversable stoppers with rubber coverings or other elastic material,
which is attended with much difficulty, careful handling of delicate tools, increasing
the cost materially, and often producing very imperfect results as compared with
my completed stopper forced into the bottle as before described, the rubber or
elastic covering withstanding the necessary pressure, and being retained in its
position by the indented rings and recesses above described. Or if desired the
stopper may be formed with recessed ends and indented ring combined as above
described.
