Improvements in Means for Preventing the Refilling of Bottles.
We LOUIS DIDIER of 64 Church Hill Road, Willesden Green, WILLIAM HINDSON
GEORGE of 83 Pursers Crown Road, Fulham, CHARLES LINCOLN CORNWELL of
25 Montpelier Road, St. John's College Park N.W. in the County of Middlesex,
and FRANCIS THOMAS MALTON of 76 Cobourg Road, Old Kent Road S.E. in the County
of Surrey, Upholsterers, 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 purpose of this invention is to prevent the fraudulent refilling of bottles that
have been once emptied that is to say to prevent the introduction of liquid into a
bottle after it has been provided with the device herein after described which is
intended to be placed in the neck after the bottle has been filled with the liquid it is.
intended to hold.
In the annexed drawing Fig. 1 is a vertical section of the neck of the bottle
provided with the device. Fig. 2 is a cross section on line 2-2. Fig. 3 is a section
on a larger scale showing the valve reversed. Fig. 4 is a cross section on line 4-4.
In the bottle neck A are made recesses B perferably three in number extending
each annularly round the bottle neck and having steep faces towards the mouth of the
bottle. After the bottle is filled the tube C is inserted, this tube is provided with two
or more spring fingers D and with two or more similar fingers D' to engage the upper
and the lower recesses B respectively. Between the fingers is a ring E preferably of
rubber, caoutchouc, or the like lying in an annular recess in the tube C and engaging
in the middle recess B. Below the tube C the bottle neck has a shoulder or
shoulders F. The interior of the tube is provided with diaphragms G preferably four
each having a passage way G' on alternate sides as indicated in Figs. 1 and 2.
Below these diaphragms G is a diaphragm H with a central hole H preferably
surrounded by an upturned flange H2 to form a seat for a valve in the form of a
cap J, which is guided by three, four, or more rods passing through the hole H' and
turned outwards.
The valve with its rods is preferably made of glass, and the tube with its
diaphragms is also of glass; the elastic fingers are preferably of steel and may be.
embedded in the glass or otherwise fixed thereto as for instance by being made.
projecting from a band encircling the tube and resting against a shoulder made
thereon.
K represents the cork which is inserted after the tube C.
On reversing the bottle the valve, taking the position of Fig. 3 will let the liquid
escape but no liquid can be again put into the bottle since the valve will become seated
as in Fig. 1. The tube C when once inserted cannot be withdrawn without breaking
it or the neck of the bottle or part of one or the other thus rendering the bottle
useless or leading to detection.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The construction comprising the bottle and the tube with recesses to receive
suring fingers whereby the tube may be inserted but cannot be withdrawn from

page_text: said neck, said tube having within it a valve and a passage way so arranged that
access cannot be had to touch said valve when the tube is inserted in the bottle neck
substantially as and for the purpose set forth.
2. The construction of bottle neck with recesses B and shoulders F. tube C packing
ring E fingers D. D' valve J and diaphragms G. H. the whole constructed for the
purpose set forth and substantially as illustrated and described.
