Improvements in Bottles and Stoppers therefor.
I, LEWIS KALLING, of 1517 West Lombard Street, in the City of Baltimore
and State of Maryland, United States of America, Bottler, do hereby declare
the nature of my invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
In the description of the said invention which follows, reference is made to the
accompanying drawing forming a part hereof, and in which,-
Figure 1 is a sectional view of the upper end of the improved bottle, and the
stopper.
Fig. 2 is a top view of the stopper alone.
Fig. 3 is an exterior side view of the stopper.
Fig. 4 is a view of the blank from which a cap forming a part of the stopper is
formed.
Figs. 5, 6 and 7, illustrate a modification in the construction of the bottle and
stopper, as hereinafter described.
Referring now to Figs. 1 to 4 inclusive, of the drawing, A is the neck of the
bottle, and B the head. The stopper consists of a cylindrical piece of cork or
other suitable substance, having its upper end and a part of the body enclosed by
an elastic cap D. The cap is preferably made from a notched sheet metal blank E,
shown only in Fig. 4, and the notches a are of such shape that when the blank is
formed into a cylindrical cap, the edges b of the metal stand slightly apart, as
shown in Fig. 3, and thereby give to the lower part of the device a certain com-
pressibility.
The cap is formed around the cork C and it is provided with an annular groove c
which in the insertion of the stopper in the bottle throat d receives an annular
projection or bead e on the inuer surface of the throat, and the stopper is thereby
held in place.
The cap D is provided with another annular groove f near its upper end, to
admit of the attachment of a suitable forked uncorking or extracting instrument,
shown in dotted lines in Figs. 1 and 2.
The extreme lower end of the cap or rather the ends of the prongs formed by
notching the cylindrical cap, are forced inward so as to grip the cork, and thereby
assist in preventing its withdrawal from the cap.
The portion of the cork projecting below the cap is somewhat larger in diameter
than the cap, as shown in Fig. 3.
In closing the bottle, the stopper is compressed in its insertion in the mouth, or
until the lower portion below the groove c has passed over the bead e, when the
stopper expands by the inherent elasticity of the cap and its contained cork. The
tightening of the joint made by contact of the cork with the glass, is increased as
the inner surface of the cork becomes moistened by the liquid contents of the
bottle.
Referring now to Figs. 5, 6 and 7 of the drawing, it will be seen that the annular
groove e instead of being in the cap D, is in the bottle throat, and the annular
bead e in place of being situated in the throat of the bottle, is on the surface of the
cap. In other words, the positions of the bead and groove are reversed, but the
result is practically the same as the adjacent surfaces of the bottle and stopper are
both corrugated circumferentially, and the locking is effected by the engagement of
the two sets of corrugations.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In combination with a bottle neck having its throat provided with circumferential
corrugations, a stopper formed of a piece of cork and a slitted metallic cap having
corrugations which practically correspond with those in the bottle throat and
thereby adapted to interlock therewith, substantially as specified.
Dated this Twenty-ninth day of June 1894.
