IMPROVEMENTS IN STOPPERING BOTTLES
Year: 1885

page_text: I, THOMAS DURRANS, Architect, of, 44, Upper Baker Street, in the County of
Middlesex, do hereby declare the nature of my Invention for "IMPROVEMENTS IN
STOPPERING BOTTLES," and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
This Invention relates to certain improvements in stoppering bottles, the especial
object of the Invention being to provide a simple effective and cheap means of
securely stoppering bottles and analogous receptacles for containing gaseous and
non-gaseous liquids and other contents.
To this end the Invention consists in forming the mouth of the neck of the bottle
of such an internal formation as that it will be adapted to receive and retain an
appropriately formed stopper inserted into its mouth, and in so forming the stopper
as that when thus inserted and retained it will be effective in compressing an
elastic ring or washer interposed between the parts externally of the bottle and in
thus stoppering the bottle and preventing escape of the contents.
The present improvements are illustrated on the accompanying drawings; in
which Fig. 1, represents a section elevation, and Fig. 2 a transverse section
through a. b: Fig. 1.
1, represents the neck of the bottle or other receptacle, the mouth end, 2, of
which is formed with an inner projecting or thickened part, 3, having two or more
equidistant grooves, 4, the upper edge of the mouth being made true or level, and
the under edge of the part, 3, being made of an inclined formation, corresponding
inclines, 5, starting from the bottom ends of the grooves, 4.
6, represents the stopper which is made of lignum-vitæ, glass, or other suitable
substance, and of a diameter capable of being freely inserted into the mouth of the
bottle, and of a length sufficient to extend below the part, 3, thereof, and is formed
adjacent to its inserted end with projecting equidistant lugs, 7, equal in number to
that of the grooves, 4, and which, when the stopper is being applied, are inserted
thereinto, and when it is pressed home in the neck of the bottle, project just below
the bottom thereof, and then firmly retain the stopper in position upon its being
slightly turned by sliding under the said inclines, and thus gradually draw the rim, 8,
of the stopper towards the end, 9, of the neck of the bottle, and compress an india
rubber or other suitable elastic washer, 10, which is placed around the stopper
immediately under its rim, 8, between the said rim and the end, 9, of the neck of
the bottle, rendering the closure thereof perfect.

page_text: By thus placing the ring of rubber quite externally of the bottle, the liability of
the same contaminating the contents thereof, as occurs in bottles provided with
inner washers, is avoided.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim, is
The herein before described improvements in stoppering bottles and analogous
receptacles, the same consisting in forming the bottle with an inner projecting
part, 3, having two or more equidistant. grooves, 4, with a level top and under
inclined edges, 5, and in forming the stopper with projecting lugs; 7, an extended
rim, 8, and an elastic washer 10, immediately below it, when such parts are formed
and arranged as illustrated on the accompanying drawings so that when combined
and used in the manner intended they shall be effective in compressing the elastic
washer between them externally of the bottle, and in retaining their respective
positions, and effecting (for as long as may be desired) a perfect closure of the
bottle, substantially as described.
