Improvements in the Construction of Bottles.
I, LOUISA LAWSON, of 156 Vickery's Chambera, 82 Pitt Street, Sydney, in the
Colony of New South Wales, Printer and Publisher, do hereby declare the nature
of this invention to be as follows:-
This invention relates to an improvement in the construction of bottles, its
object being to provide a bottle which, having been once filled and sealed canno
be opened without rendering the bottle unfit for further use.
I propose to construct my improved bottle in the following manner :-
The body will be provided with a tube-like opening in the centre, extending
from the bottom upwards to a point in close proximity to the shoulder, where the
tube becomes wider, and is closed by a thin glass film, the centre of which is
slightly lower than its outer edge. A trade mark may be blown in this film
which will be destroyed in the operation of opening the bottle. The said tube like
opening is narrower in the centre than at either end and is left open where it
joins the bottom of the bottle and may be better described as an extended frog.
The bottle neck is somewhat cone shaped so as to permit of a cork wider at the
bottom than the top being placed therein, it is preferable however to use two
corks (a lower and an upper) for sealing the bottle, the bottom of the lowermost
cork would almost touch the glass film before described. A sufficient space is
left between the shoulder of the bottle and the outer edge of the top of the tube
like opening, to permit of liquid being passed in or out of the bottle.
To open the bottle after having been filled and corked a corkscrew is necessary
the point of which on being worked through the cork or corks will break the
glass film, the fragments falling out of the bottle through the tube, thus rendering
the bottle unfit for future use.
Modifications may be made in the position of the tube but in all cases it will
terminate immediately beneath the cork.

page_text: 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 object of the present invention is to provide an Improvement in the
construction of bottles, so that it will not be possible to refill same, and thus
prevent fraud.
The construction of my Invention is such that in the uncorking, it is necessary
to partially destroy the bottle, and thus render it useless, but in order that it may
be more fully understood reference will be made to the accompanying drawing,
forming part of this specification, and which shows a sectional view of my
improved bottle.
A is the body of the bottle which may be any desired shape and size having in
the centre, a tube like opening B, extending from the bottom upwards to a po at
just below the bottom of the cork C. This tube like opening is circular and of n
at the bottom and the sides of same are preferably curved inwards, so that .ne
centre may be somewhat narrower than the ends, the top is closed with a circu ar
thin glass film D, which is preferably convex in section, but may be flat. A Trude
Mark or brand may be blown in this glass film ]).
The opening B may be somewhat better described as an extended frog and
sufficient space E is left between the top and the shoulders F of the bottle to permit
the liquor being poured in or out.
The neck G of the bottle is somewhat cone shaped, being slightly wider at
the bottom than at the top.
In corking the bottle after it has been filled with liquor, it is preferably done
with two corks, a lower cork C, and an upper cork H, the object being to compel
the person uncorking the bottle to insert the corkscrew right through the lower-
most cork. If desirable a single cork may be used in lieu of the two corks as
above mentioned.
When my improved bottle is used, and after being filled with liquor and corked,
a person uncorking the bottle will have to use a corkscrew to draw the cork or
corks, and in doing so the point of the corkscrew will pierce the glass film D,
and cause the same to break and fall down the opening B and out of the bottle.
The Trade Mark or Brand blown in the film 1) would thus be destroyed.
The bottle would then be useless, once the liquor had been poured out, as it
would be impossible to replace the glass film D, thus once the bottle is uncorked
it cannot be again used for placing on the market. A modification may be made
in starting the opening B, from one side of the bottle, instead of from the bottom,
but in any case it would terminate just below the cork and have the thin glass
film D, as before described.
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 the construction of bottles, a tube like opening or extended frog, starting
from the bottom or side of the bottle, and extending to a point just below the cork,
the outer end being open, and the inner end being closed with a thin glass film,
substantially as herein described, explained and illustrated in the drawings.
