NATHAN THOMPSON, of Brooklyn, in the County of Kings, and State of New
York, in the United States of America, but at present of 23, Southampton
Buildings, in the County of Middlesex. IMPROVEMENTS IN MEANS FOR CLOSING
OR STOPPING BOTTLES, JARS, AND OTHER SIMILAR VESSELS."
The Invention has for its object improvements in means for closing or stopping
bottles, jars, and other similar vessels.
For this purpose according to one arrangement I form the top edge of the bottle
neck very narrow, preferably of a A section, and I form such neck with a projecting
ring or collar extending a short distance from the upper edge thereof. I apply to
the bottle neck formed as above a cap of metal, the top of which is formed with
one or more inclines and stops, and I line such cap with cork or other suitable
packing material extending entirely across the same, or only in an annular form.
The entrance into the bottle neck I preferably form somewhat sharply coned
and I form an annular groove or chase in the cork or other packing to fit the
upper edge of the bottle neck and a short distance down on either side thereof, or
I form the cork or other packing with a flat portion to rest on the upper edge of
the bottle neck and a conical part to pass into the interior thereof.
When the cap or stopper is placed in position it is firmly pressed down onto the
bottle neck, and a clip or strap fitting over the cap or stopper and taking a bearing
under the ring or collar on the bottle neck is pressed over the cap or stopper until
31

page_text: it comes against the stop or stops on the latter, when in consequence of the upper
portion of the strap or clip having risen up the incline or inclines on the cap or
stopper, the cork or other packing is firmly pressed down on to the neck of the
bottle.
According to another arrangement I form the neck of the bottle or other vessel
with a projecting ring or collar, as before described, a short distance below the top
thereof, and with flat upper and lower surfaces. In connection with such bottle
neck I employ a cap provided as before described with one or more inclines and
stops, but provided also with a cylindrical part passing over the upper and smaller
part of the bottle neck and with a projecting ring or flange terminated with a
sbort descending cylindrical part to receive a ring of india rubber or other suitable
packing, which when the cap or stopper is applied to the bottle, rests on the upper
surface of the projecting ring or collar on the bottle neck, then by the application
of one or more straps or clips as before described the cap or stopper pressed
firmly to its seat.
By this last described arrangement the packing is almost completely isolated
from the interior of the bottle and its contents.
The caps or stoppers herein described may be stamped up out of sheet metal, or
they may be cast or otherwise formed of solid material, and in some cases I form an
annular groove around the cap or stopper to receive a ring or strip of cork or other
packing material to act in combination with the bottle neck herein first described;
or a disc of cork or other packing material may be applied entirely across the cap,
and on being submitted to pressure the cork or other packing may be forced by the
bottle neck into an annular A shaped groove formed in the cap or stopper. The
stopper may be formed solid of gutta percha or other material requiring no other
packing material to be applied thereto, and I sometimes in lieu of the strap or clip
before mentioned, connect to the stopper tape, webbing, or wire, and wire the same
tightly on to the bottle neck, or I-simply press the stopper down firmly onto
bottle neck, and wire it in position.
