JOSEPH BROEL, of Gravesend, in the County of Kent, Gentleman. "IMPROVEMENTS.
IN STOPPING BOTTLES, JARS, AND OTHER LIKE RECEPTACLES, AND IN THE MEANS OR
APPLIANCES TO BE EMPLOYED THEREIN."
This Invention relates to certain improved modes of and means or appliances for
stopping the mouths of bottles, jars, and similar receptacles containing aerated and
other liquids or substances, and consists, according to one arrangement, which is
more particularly applicable for aerated liquids, of a bottle, the neck of which is
pinched or slightly flattened at the lower part thereof during the process of its
manufacture so as to impart an oval or equivalent shape to the opening in that
part of the neck whilst leaving the upper part of the neck circular. Inside this
neck thero is fitted a stopper composed of metal, glass, porcelain, or any other
suitable material of a corresponding shape to the interior of the neck, that is to
say, the upper part of the stopper is circular in horizontal section, whilst its lower
end is pinched or flattened laterally so as to assume an oval or equivalent shape,
the ends of the oval projecting slightly beyond the two opposite sides of the stopper
at its lower part, whilst its largest diameter does not exceed that of the upper
rounded portion of the stopper, so that the oval portion shall be free to enter the
neck. When the stopper is inserted the oval part passes through the corresponding
portion of the opening, and by turning the stopper partly round it will be locked
within the neck by the projection of the oval portion of the stopper passing
underneath the flattened portion of the neck. In order to ensure a perfectly tight
closure of the bottle neck a packing ring of india rubber, cork, or other suitable
material is fitted in an annular groove in the round part of the stopper, by
preference near the upper end, or if desired the said ring may be fitted in a groove
inside the round part of the neck.
According to another arrangement, more particularly applicable to wide mouthed
bottles and jars, such, for example, as are used for pickles and jams, an outer cap of
glass, porcelain, wood, white metal, or other suitable material is made to fit over
or outside the inouth of the vessel, and is provided with a central plug or stopper
inside to fit at the same time into the interior of the mouth or neck. In order to
secure or lock the said combined cap and stopper in position one, two, or more

page_text: grooves or slots are formed down a projecting portion on the outside of the neck,
and corresponding projections are made at the bottom of the inside of the cap, so
that by turning the cap and stopper slightly the projections on the cap will pass
beneath the projecting portions between the grooves on the exterior of the neck,
the surfaces being if desired slightly concavo to prevent any chance of the
projections on the cap accidentally slipping back to the grooves or slots and so
becoming released. If desired the part which fits outside the neck may, when
made of metal or suitable material, be in the form of a strap with internal
projections at its ends passing through the grooves and being locked as above
described. It is obvious that the positions of the grooves and projections for locking
may be reversed, the projections being formed on the outside of the neck and the
grooves on the inside of the cap. The portion which enters the neck or mouth is
made to fit air tight by the application of a suitable packing ring either to the
stopper or neck as previously described. In both the arrangements of stoppers and
caps a convenient head or appliance is provided on the top for the facility of 1
turning and handling the same.
