13 Claims. (Cl. 215—32)
This invention relates to a bottle intended to
insure the genuineness of its contents at the
time of the purchase of the bottle and its con
tents by the ultimate consumer. Bottles of this
5 general class have particular utility at the pres
ent time in the marketing of wine, whiskey and
other spirituous liquors.
Because of the activities of bootleggers, who
have operated to defraud the United States Gov
10 ernment of taxes by utilizing old bottles, par
ticularly bottles which have contained some of
the better and more widely advertised brands
of spirituous liquors, which they re?ll and seal
with counterfeit seals, and because of the conse
15 quent defrauding of legitimate distillers of good
whiskies and the makers of other spirituous liq
uors, considerable inventive e?ort has been di
rected toward the discovery of a bottle which
would completely foil the bootlegger.
These efforts have been mainly along two lines:
in the ?eld of what are known as non-re?llable
bottles, that is, bottles which retain their iden
tity but are supposed to be so designed that when
the contents are removed they cannot be re?lled,
25 and in the ?eld of what I prefer to term “non
repackageable” bottles, that is, bottles which
when once opened may never again be re?lled and
resold as an original package because, in the act
of opening the bottle, an integral portion of the
bottle must be destroyed.
Because of the fact that bottles are necessarily
made of glass which, even when annealed by the
most modern annealing methods, still has ex
tensive internal strains, attempts heretofore
,35 made to provide a satisfactory non-repackage
able bottle, particularly for use in the marketing
of spirituous liquors, have proved to be abortive.
These attemlpts to design a non-repackageable
bottle, which necessarily involve a breaking away
40 from the bottle structure of what has been an
integral portion thereof, have been of such de
sign and character that splintering' or slivering
of the glass practically always occurs in the
breaking operation and that, in addition, there
is apt to appear upon the part of the bottle which
remains, an extremely sharp and frequently
jagged edge likely to injure the hand of the user.
Also, the breaking could not be controlled so as
to- follow a de?nite line of cleavage which could
be depended upon.
It will be readily appreciated
that in this art the breakage must be certain and
along de?nite lines in each case. Even one bad
break in ?ve thousand bottles would make a par
55 ticular type of bottle unsatisfactory,
For this
reason, there is not on the market today a single ‘ A
non-repackageable bottle as herein de?ned.
Even in those cases where the bottles have
been so designed that the slivers or splinters of
glass would not be likely ‘to remain in such posi
tion as to appear later in’ the drink itself, no
attempt has been made to eliminate automati
cally the danger due to the leaving of sharp
vand/ or jagged edges on the bottle itself. More
over, it is obvious that the splintering or slivering
of the glass in the act of opening the bottle, with
the consequential scattering of the splinters or
slivers about the point of opening, is objection
able, as anyone will appreciate who has under
taken to locate glass splinters or slivers on ?oors 15
or rugs. This is especially true when bottles are
opened in private homes, as is so commonly the
practice under the present methods of vending
spirituous liquors.
A further reason why so many attempts here
tofore to make non-repackageable bottles have
proved to be abortive is that their designs have
been impracticable from the standpoint of
economical manufacture in bottle making plants.
The present invention aims generally so to de
sign and construct a bottle of the non—repack
ageable type as to eliminate the objections in
part above recited which have rendered the at
tempts heretofore made‘ to solve the non-repack
ageable bottle problem abortive.
More particularly the invention aims to pro- I
vide a bottle, so constructed as to require the
breaking from the bottle of an integral portion
thereof to obtain access to its contents, which is
also so designed and constructed that the break 35
ing act may be performed with consistency with
the practical elimination of liability to the for
mation of splinters or slivers.‘
The invention further aims to insure that in
the rare event that slivers or splinters should be
formed there will be no scattering of these about
the point of the bottle opening and no danger of
their ever either entering the bottle or any con
tainer into which its contents may be poured nor
of their in any way injuring the one who opens 45
the bottle or anyone who» thereafter uses it.
In addition to providing for a splinterless
breaking off of the removable part of the bot
tle and for insurance against scattering splinters
in the rare event of a defectively annealed bot
tle not responding to the normally to be expected
rupturing action, the invention aims to- insure
that there will be left exposed on the opened bot
tle no sharp and/or jagged edges which could in
anyway injure the user of the bottle.
In addition to providing a bottle requiring the
destruction of a, portion thereof to obtain access
to its contents, which will overcome the objec

rupturing force to a tapering section of the neck
at each end of the slot, and then to the full cross

obtaining of a rupturing action rather than a
the invention aims also so to improve the design of
a non-repackageable bottle as to facilitate both
its manufacture and its ?lling. These impor
tant featuresof the invention will be referred to
incidentally in connection with the following list

restricted portion of the neck into the enlarged

tured or otherwise injured by the act of in

operation of breaking off the removable part of
the bottle neck. In addition the ferrule forms
a limit surface against which the resilient cov

neck portion is removed, and for the purposes
already indicated and hereinafter emphasized.
Important features of the invention are the ar
rangement of this cork extension and its sur
rounding ferrule in a chamber formed by a re
movable part of the'bottle neck which has its
inner wall so spaced from the cork ferrule that
the rupturing operation ordinarily will not cause
engagement of the removable part of the bottle
neck with the ferrule; the location of the rup
ture-initiating slot at a point sufficiently above
the restricted portion of the bottle neck and
Within the enlarged portion thereof as to provide
a cavity into which, in the rare event of the
3O formation of slivers or splinters, these slivers or
splinters may fall or be forced by the contract
ing action of the surrounding resilient sleeve and
the provision of a shoulder upon which the fer
rule seats itself both to determine the position of
the cork and to provide a positive stop for the
stopper, thereby positively locating the upper
face of the stopper at a predetermined point in
the bottle neck.
Other important features of the invention to

bottle neck of a rib or bead extending both above

Referring now more particularly to the draw—

which abuts against a shoulder l3 and limits the
inward movement of the cork II. The cork II is,
however, preferably long enough so that it ex 30
tends downward into the bottle beyond the most
restricted portion of the neck in order to expand
into an enlarged portion and thus resist too easy
removal. The ferrule l2 preferably extends over
the upper edge of the cork II and thus provides
an abutment for the head N5 of a stopper l5
which‘ may be made of porcelain or any other
suitable material and which serves with the cork
