Improvements in or relating to Caps for Bottles and similar
Receptacles.
We, LA SOCIETE ROGER & GALLET, Perfumers, of 38, Rue d'Hauteville, Paris,
in the Republic of France, do hereby declare the nature of this invention to be
as follows:-
This invention has for its object an improved cap or capsule for bottles flasks
and similar receptacles, arranged so that it must necessarily be broken when the
bottle is opened, whilst it may have the appearance of a skin or parchment cap
such as is often used for scent and other bottles.
The characteristic feature of the cap according to the present invention consists
in the use of a compound having a basis of gelatine preferably rendered opaque
by any suitable substance and subjected after having been placed on the bottle,
to the action of a reagent which hardens it and enables it to resist heat and
humidity.
The process may be carried out as follows: -
1st, a paste is prepared containing the following substances:-
Gelatine, glycerine, oxide of zinc, sugar and water. The proportions may be,
for instance, as follows:-
Water
Gelatine
Glycerine
Oxide of zinc
Sugar
400 to 700 parts.

To manufacture the caps a core or former is used having the shape of the neck
of a bottle and may be provided with an engraving or ornamentation either to
render the appearance of the cap more attractive or to produce a trade or other
mark.
The core is dipped into the hot paste, withdrawn and cooled.
The part of the core which has been dipped into the paste. thereby becomes
covered with a film which after cooling retains its elasticity. The cap is then
removed from the core, and may be turned inside out if necessary either in
removing it from the core or afterwards. The cap then shows the inscription or
ornamentation-engraved on the cores in intaglio-in relief.

page_text: The top of the cap is then provided with a hole much smaller than the plug of
the stopper to be used.
The plug can enter the hole owing to the elasticity of the material of the cap,
which immediately afterwards contracts again and fits round the reduced upper
portion of the stopper.
When the stopper is thus provided with its cap, it is introduced into the bottle
to be stoppered the lower part of the cap embracing the neck of the bottle.
Then the cap is hardened so as to enable it to resist the action of heat and
humidity.
This may be effected by subjecting the cap in place on the bottle to any
suitable reagent; formic aldehyde being particularly suitable and giving excel-
lent results.
After this operation it is absolutely impossible to withdraw the stopper from
the bottle without breaking the cap. In this manner a safety closing device
is obtained for bottles and the like.

Improvements in or relating to Caps for Bottles and similar.
Receptacles.
We, LA SOCIETE ROGER & GALLET, Perfumers, of 38, Rue d'Hauteville, Paris,
in the Republic of France, 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:—
This invention has for its object an improved cap or capsule for bottles flasks
and similar receptacles, arranged so that it must necessarily be broken when the
bottle is opened, whilst it may have the appearance of a skin or parchment cap,
such as is often used for scent and other bottles.
In order to make the invention better understood the different stages of
manufacture of a cap according to the present invention are illustrated by way of
example in the accompanying drawings.
The characteristic feature of the cap according to the present invention consists
in the use of a compound having a basis of gelatine, or like substance, preferably
rendered opaque by any suitable substance, and subjected after having been
placed on the bottle, to the action of a reagent which hardens it and enables it
to resist heat and humidity.
The process may be carried out as follows:
-
1st, a paste is prepared containing the following substances:-
Gelatine, glycerine, oxide of zinc, sugar and water. The proportions may be
for instance, as follows:-

To manufacture the caps, a core or former A (Fig. 1) is used having the
shape of the neck of a bottle, and, it may be provided with an engraving or

page_text: ornamentation either to render the appearance of the cap more attractive, or
to produce a trade or other mark.
The core A is dipped into the hot paste, withdrawn and cooled.
The part of the core which has been dipped into the paste thereby becomes
covered with a film which after cooling retains its elasticity. The cap is then
removed from the core, and may be turned inside out if necessary either in
removing it from the core, or afterwards. The cap then has the shape shown in
Fig. 2 and the inscription or ornamentation-engraved on the cores in intaglio,-
appears on the cap in relief.
The top a of the cap is then provided with a hole b, much smaller than the
plug c of the stopper to be used. The plug can enter the hole 6 owing to the
elasticity of the material of the cap, which immediately afterwards contracts
again and fits round the reduced upper portion of the stopper as shown in Fig. 3.
When the stopper is thus provided with its cap, it is introduced into the bottle
to be stoppered, the lower part of the cap embracing the neck of the bottle
(Fig. 4).
Then the cap is hardened so as to enable it to resist the action of heat and
humidity.
This may be effected by subjecting the cap in place on the bottle to any
suitable reagent; formic aldehyde being particularly suitable and giving excel-
lent results.
After this operation it is absolutely impossible to withdraw the stopper from
the bottle without breaking the cap. In this manner a safety closing device
is obtained for bottles and the like..
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. A safety cap for bottles flasks and similar receptacles substantially as
described.
2. The method of forming a safety cap for bottles flasks and similar receptacles
substantially as described.
3. A safety cap for scent or other bottles consisting of a film having gelatine
or like substance as a base, said cap being subjected after having been put in
place to the action of a hardening reagent substantially as and for the purpose
described.
