PROVISIONAL SPECIFICATION.
An Improved Seal or Disc of Guarantee of Authenticity applicable
to Flasks and Bottles of all descriptions.
I, VALENTIN DINGREVILLE of Saint Evroult (Notre Dame du Bois) Depart-
ment de l'Orne in the Republic of France, Glass Manufacturer, do hereby
declare the nature of my invention to be as follows:-
My invention relates to seals applied to flasks & bottles of all descriptions, as
guarantees of authenticity as to the nature of the contents contained therein, and
has for its object the construction of the scal or disc in a simple and novel form.
The seal which is formed of glass is constructed so as to co-act with a special
lodgement arranged upon the neck of the flask so that in order to open the same,
it is only necessary to destroy the disc or seal.
The engagement of the seal with the neck of the bottle is effected as follows:-
In the interior of the neck of the bottle or flask, one or more mortises or grooves
are arranged (preferably two in number), each one being formed as a right angle,
viz.-running down vertically from the top of the neck and then turning
horizontally at a right angle.
The seal is formed as a disc and is provided with one or more tenons or pro-
jections extending outwards from its periphery, of such a size and number as to
engage with the aforesaid grooves and mortises in the neck of the flask.
It has also a groove arranged diametrically across its under face.
The thickness of this part where the groove is situated is very little and is
consequently very weak compared with the other part.
To put the seal in place, the tenons must be inserted in the vertical portion of
the channels or mortises in the neck of the flask; then by giving it a small rotary
movement from left to right or vice versa, the tenons become engaged in the
horizontal portion of the grooves or mortises.
It thus makes a joint similar to a bayonet joint.
The ordinary cork is of course first inserted into the bottle in the usual manner
and is situated directly below the seal or disc.
When the seal or disc is in position the mortises or channels are filled up by
means of any suitable cement, such as for example a mixture of albumen and
ground or crushed glass.
This cement retains the disc in place, so that the disc cannot be raised without
breaking it owing to its being so fragile.
It is therefore obvious that it is impossible for the person who has emptied the
bottle of its contents or any other person finding the bottle empty, to restore the
sealing to its original form or condition as the particular scal or disc no longer exists
as a whole. Thus the seal or disc represents to the consumer the absolute
guarantee of the origin of the contents of the flask, and it is equally for the manu̟-
facturer a security against the refilling of his bottles with any liquids not coming
from his house.
It is quite obvious that the sizes and dimensions of the seal of guarantee can
vary according to the nature, capacity, and destination of the flasks which are
sealed by them.
In addition to this my invention can be applied not only to flasks and bottles
but to all other vessels having a neck whether made in glass, ceramic or other
material.

An Improved Seal or Disc of Guarantee of Authenticity applicable
to Flasks and Bottles of all descriptions.
I, VALENTIN DINGREVILLE, of Saint Evroult (Notre Dame du Bois) Depart-
ment de l'Orne, in the Republic of France, Glass Manufacturer, 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:
My invention relates to seals applied to flasks and bottles of all descriptions, as
guarantees of authenticity as to the nature of the contents contained therein, and
has for its object the construction of the seal or disc in a simple and novel form.
The seal which is formed of glass is constructed so as to co-act with a special
lodgement arranged upon the neck of the flask, so that in order to open the same,
it is only necessary to destroy the disc or seal.
.
In order that my invention may be the better understood I now proceed to
describe it in relation to the drawings hereunto annexed, reference being had to
the letters and figures marked thereon.
Figure 1 is a front elevation of a bottle fitted with a scal according to my
invention.
Figure 2 is a plan of same.
Figure 3 is a sectional elevation at the neck with the cork in place, the lower
part of the bottle being in full.
Figure 4 is a view. of Figure 3 with the cork removed.
Figure 5 is a plan of Figure 4.
Figure 6 is an under and side view of the seal.
In the figures like parts are designated by like letters.
In the interior of the neck b of the bottle or flask a one or more mortises or
grooves c are arranged (preferably two in number) cach one being formed as a right
angle viz. running down vertically from the top of the neck and then turning
horizontally at a right angle as shown in Figure 4.
The seal is formed as a disc d and is provided with one or more tenons or pro-
jections e extending outwards from its periphery of such a size and number as to
engage with the aforesaid grooves or mortises c in the neck of the flask.
It has also a groove arranged diametrically across its under face.
The thickness of this part in the middle as shown at in Figure 6 where the
groove is situated, is very little, and is consequently very weak compared with the
other part.
To put the seal in place, the tenons e must be inserted in the vertical portion of
the channels or mortises c in the neck of the flask then by giving it a small rotary
movement from left to right the tenons become engaged in the horizontal portion
of the grooves or mortises c.
It thus makes a joint similar to a bayonet joint.
As shewn in Figures 1 and 3 the ordinary cork y is first inserted into the bottle
in the usual manner, and is situated directly below the seal or disc.
When the seal or disc d is in position the mortises or channels c are filled up by
means of any suitable cement such as for example a mixture of albumen and ground
or crushed glass.
This cement retains the disc in place so that the disc cannot be raised without
breaking it, owing to its being so fragile.
It is therefore obvious that it is impossible for the person who has emptied the
bottle of its contents or any other person finding the bottle empty, to restore the
sealing to its original form or condition, as the particular seal or disc no longer
exists as a whole.
Thus the seal or disc represents to the consumer the absolute guarantee of the
1.

page_text: origin of the contents of the flask, and it is equally for the manufacturer a security
against the refilling of his bottles with any liquids not coming from his house.
It is quite obvious that the sizes and dimensions of the seal of guarantee can
vary according to the nature, capacity, and destination of the flasks which are
sealed by them.
In addition to this my invention can be applied not only to flasks and bottles
but to all other vessels having a neck, whether made in glass, ceramic or other
material.
-
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
An improved seal or disc of guarantee of authenticity for bottles or flasks,
consisting of a piece of fragile material, having tenons or projections, which engage
with convenient lodgements arranged within the neck of the bottle, substantially as
described and illustrated in the accompanying drawings.
