Improvements in Bottle Stoppers or Capsules.
We, JOHN BAPTISTA NEUENDORFF and ULRICH HERMAN RISCHE, both of San Antonio,
in the State of Texas, United States of America, Gentlemen, 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 :-
The invention relates to improvements in bottle stoppers. The object of the
present invention is to improve the construction of bottle stoppers and to enable a
metallic sealing cap to be readily removed from the neck of a bottle without the use
of an instrument.
The invention consists in the construction and novel combination and arrangement
of parts, as hereinafter fully described, illustrated in the accompanying drawings and
pointed out in the claims hereto appended.
In the drawing-
Figure 1 is a perspective view of a portion of a bottle, provided with a stopper
constructed in accordance with this invention.
Figure 2 is a vertical sectional view of the same.
Figure 3 is a detail view of the device, prior to its application to a bottle.
Figure 4 is a plan view of the blank from which the sealing cap is constructed.
Figure 5 is a reverse plan view of the sealing-cap the extracting string being
removed.

Like numerals of reference designate corresponding parts in the several figures of
the drawings.
1 designates a sealing cap constructed of metal and provided with a locking
flange 2 which engages an annular shoulder 3, of a bottle 4, and which is crimped or
bent into locking contact with the same. The metallic sealing cap contains a sealing
disk 5, of cork or any other suitable material. The crimping or bending of the
locking flange is effected while the sealing disk is under pressure, and heretofore an
instrument and the exertion of considerable force were necessary in order to remove
the stopper from the bottle.
In order to enable the stopper to be readily removed from the bottle without
employing an instrument, the cap is provided at one side with an integral strip or
tongue 6 and has grooves or partial cuts 7 disposed in alinement with the side edges
of the strip or tongue 6 and extending across the cap from the adjacent portion of
the locking flange to within a short distance of the flange at the opposite side of the
cap. The locking flange is provided between the grooves or partial cuts 7 and the
strip or tongue 6, with slots 8, which facilitate the crimping of the flange at the strip
or tongue and which terminates short of the periphery of the said flange. The blank
from which the cap is constructed is illustrated in Figure 4 of the accompanying
drawing, and the small quantity of material at the outer or lower terminals of the
slots connecting the strip or tongue with the adjacent portions of the locking flange
is easily broken and the grooves or partial cuts, extending from the inner or upper
terminals of the slots, permit the tongue and the metal between them to be readily
torn off. The stopper is thus readily removed from the neck of the bottle without
employing a key or other form of instrument. The partial cut or groove 7 may be

page_text: extended entirely across the top of the cap, instead of terminating a short distance
from one side, and the depending strip or tongue 6 may be duplicated to provide a
pair of handles, as illustrated in dotted lines in Figure 2 of the drawing.
The strip or tongue is provided between its ends with reversely arranged triangular
openings 9, formed by cutting the metal at two sides, and the partially severed
tongues or spurs are bent inward toward each other, against the inner face of the
tongue or strip, to avoid cutting an extracting wire or string 10, which affords a
convenient grip in tearing off the tongue or strip. The wire, cord or string is doubled
to form a loop and the doubled or looped portion is passed through the openings 9 and
and receives the body-portion, as illustrated in the accompanying drawings,.
whereby the cord or string is readily fastened to the strip or tongue. Instead of
making the openings triangular, as above described, they may be constructed circular
or any other desired shape, but the triangular form is preferable when a cord is
employed.
The invention has the following advantages:
The metallic sealing cap is capable of securely retaining the sealing disk on the
upper edges of the neck of the bottle and it is adapted to be readily removed without
the use of a key or other instrument. The slots adjacent to the strip or tongue
facilitate the crimping of the flange at that point, and the metal at the outer or
lower terminals of the slots, is readily broken when it is desired to tear the
strip or tongue from the cap for removing the latter. The grooves and slots do not
impair the efficiency of the cap in retaining the sealing disk on the bottle.
Changes in the form, proportion, and the minor details of construction may be
resorted to without departing from the spirit or sacrificing any of the advantages of
this invention.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. A bottle stopper comprising a metallic cap provided with a locking flange
adapted to be crimped or bent into locking contact with a shoulder of a bottle, said
cap having a strip or tongue at one side of the locking flange and having a central
weakened portion, adapted to be readily torn off with the strip or tongue, whereby the
cap is removed, substantially as specified.
2. A bottle stopper comprising a metal cap having a crimped locking flange and
provided at one side thereof with an integral strip or tongue, said cap being provided
at its top with grooves or partial cuts disposed in alinement with the side edges of
the strip or tongue, the locking flange being slotted between the latter and the
grooves or cuts, and a sealing disk arranged within the cap, substantially as
described.
3. A bottle stopper comprising a metallic sealing cap having a crimped or bent
locking flange and provided at one side with a strip or tongue and being weakened
opposite the same, said tongue or strip being provided with opposite openings and
having the portions separated through the formation of the openings bent towards
each other, and an extracting string looped through the openings, substantially as
specified.
