PROVISIONAL SPECIFICATION.
Improvements in or relating to the Prevention of Fraud concerning
the Contents of Glass Bottles and the like.
I, ELSIE KATE JOSEPHSON, of Heath House, Manor Road, East Molesey, in the
County of Middlesex, Gentlewoman, do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to prevent a common form of fraud consisting in
filling bottles of well-known makes with spurious contents. This I effect in the
following manner: -
The bottle may be of ordinary construction excepting as regards the neck, in
which I form a circumferential indentation or channel upon the outside and prefer-
ably projecting upon the inside. In this channel I may if desired placed a wire
or equivalent. After the bottle is filled a cork or equivalent plug of any suitable
thickness may be placed at or about the beforementioned projection, and the top of
the bottle may then be sealed up with a blow pipe or otherwise as desired. To
obtain access to the contents the neck may be struck when it will break at the
circumferential indentation, so that upon the withdrawal of the cork the bottle is
incomplete, and would show that it had been opened after it was originally
sealed.
The cork or equivalent could be used for temporarily closing the neck, so that if
the whole of the contents were not used at once they could be kept securely
corked.

Improvements in or relating to the Prevention of Fraud concerning
the Contents of Glass Bottles and the like.
I, ELSIE KATE JOSEPHSON, of Heath House, Manor Road, East Molesey, in the
County of Middlesex, Gentlewoman, 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 object of this invention is to prevent a common form of fraud consisting in

following manner: —
The bottle may be of ordinary construction excepting as regards the neck, in
which I form a circumferential indentation or channel upon the outside and prefer-
ably projecting upon the inside. In this channel I may if desired place a wire
or equivalent. After the bottle is filled a cork or equivalent plug of any suitable
thickness may be placed at or about the beforementioned projection, and the top of
the bottle may then be sealed up with a blow pipe or otherwise as desired. To
obtain access to the contents the neck may be struck when it will break at the
circumferential indentation, so that upon the withdrawal of the cork the bottle is
incomplete and would show that it had been opened after it was originally
sealed.
The cork or equivalent could be used for temporarily closing the neck, so that if
the whole of the contents were not used at once they could be kept securely
corked.
In the accompanying drawings
Figure 1 is a sectional elevation of a bottle neck made in accordance with this
invention.
Figure 2 is a similar view of a bottle neck with the cork inserted and sealed,
Figure 3 is a similar view of the bottle neck after the top has been broken off
preparatory to opening the bottle.
Like letters, indicate like parts throughout the drawings.
In the neck A of the bottle, a short distance from the mouth is formed a circum-
ferential indentation B, the glass or other material of which the bottle is made
being thinned at this point, the indentation however, being sufficient to cause a
rib or ridge A¹ to be raised on the interior of the neck. After the bottle has been
duly filled the cork C, which is a moderately loose fit in the neck of the bottle
except at the rib A³, is inserted so that approximately half of it lies on either side
of the rib. The glass round the mouth of the bottle is now fused over the cork
as at A³ forming an air-tight closure.
When it is desired to open the bottle the top part above the indentation B is
struck sharply causing it to break off on the weakened line. The top of the bottle
now has the appearance shown in Figure 3. The cork may now be abstracted in
the usual manner and replaced if desired. The position of the cork prevents the
possibility of any splinters of glass entering the bottle.
If desired a wire may be arranged to lie in the indentation B for the purpose of
carrying any particular seal or for other purposes.
It is to be noted that though the circumferential indentation produces a weakened
line in the bottle neck this does not constitute a material weakness in the neck of
the bottle, but merely ensures the fracture occurring uniformly, and at a desired
point.
Although this invention is chiefly applicable to glass bottles it is not restricted
to this class of bottle.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. In a device to ensure the detection of fradulent refilling of bottles fusing the
top of the bottle over the cork and weakening the neck of the bottle between the
extremities of the cork whereby the top can be readily broken off.
2. A bottle with a circumferential indentation such as B in the neck between the
extremities of the cork for the purpose described.
3. In a device to ensure the detection of fradulent refilling of bottles the combina-
tion with the cork of a bottle neck the end of which is fused over the cork and a
circumferential weakening of the bottle neck between the extremities of the cork.

as described and illustrated in the accompanying drawings.
