Improvements in Bottle-sealing Devices.
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 this invention, 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 that class of battle-sealing
devices, wherein a sealing cap is applied to the outside of the bottle head.
The said invention consists in the combination with a bottle head, of a cap
having a hollow bead in its lateral or side wall, in which is enclosed a compressible
gasket, the said cap being applied to the outside of the bottle head and the bead
thereof crushed or flattened onto the gasket to form a tight joint, substantially as
hereinafter described.
In the further 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 side view of the improved cap, in a condition for
application to the bottle head.
Fig. 2 is a top view of the same.
Fig. 3 is a sectional view of the upper end of the bottle, together with the cap,
before the formation of the joint.
Fig. 4 is a view similar to Fig. 3, except that the joint is formed.
Fig. 5 illustrates a modification in the invention, as hereinafter fully described.
Referring now to Figs. 1, 2, 3 and 4, of the drawing, A. is the bottle, and a the
head thereof. The head is shown as having a cylindrical exterior, and devoid of
any grove or depression in its surface.
B is the sealing cap which consists of the cylindrical wall and the crown c.
Within the wall & is formed an annular groove d, and the metal around the said
groove as seen from the outside of the cap, constitutes a bead.
C is a gasket of rubber, or any other similar substance, situated in the groove d.
This gasket need not conform in shape to the groove, and while the groove is
semi-cylindrical in cross section, the gasket may be a band of rectangular cross
section, as shown in Figs. 1 and 3.
To apply the cap containing the rubber-band gasket to the bottle head and form
a tight-joint, the cap is placed over the head and .while it is held down, not
necessarily with any pressure, the hollow bead d is flattened by the application to
it of a tool or machine especially adapted for the purpose. After the flattening
operation, the bead and the inclosed gasket appear as shown in Fig. 4, wherein the
gasket is compressed and entirely fills the hollow, flattened head.
In Figs. 1, 3 and 4, I show a disk of cork or some other substance of similar
character, situated between the crown of the cap and the end of the bottle head.
This disk is not intended to make a joint in any sense of the word, as the joint is
formed entirely by the flattening of the hollow bead upon the gasket which is
thus brought closely in contact with and compressed against the outer surface of
the bottle head, but as a means to protect, to some extent, the inner surface of
the crown of the cap from contact with the contents of the bottle. In other words
it is used merely as a water-proof coating for the metallic cap, and its use may be
dispensed with entirely without affecting the utility of the cap, or the joint formed
as described.
In Fig. 5, the bottle head is nearly spherical, or of the shape commonly found
in bottles used to hold malt liquors under gas pressure. In this case, the joint is
formed at or slightly below the part of the head which has the greatest diameter.

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 head, a cap to fit over the same, having a hollow
bead in its side or lateral wall and a gasket situated in the hollow bead, or between
the lateral wall of the cap and the exterior surface of the bottle head, the said
bead being crushed or flattened onto the gasket so as to distort its original shape
and thereby form a tight joint, substantially as specified.
Dated this Seventh day of May 1896.
