improvements in Stoppers and Covers for Jars, Canisters, and other
like Vessels.
I JOHN HENRY JOHNSON of 47 Lincoln's Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this Invention which has been communi-
cated to me from abroad by Eugène Fournier of 48 Rue de Bondy Paris in the
Republic of France Pharmaceutical Chemist to be as follows :-
This invention has for its object providing an hermetic closure for jars, canisters
and other like vessels which can be employed in combination with hygroscopic, anti-
septic or other preservative agents contained in a hollow or cavity provided for their
reception in the body of the stopper or cover. In the case of glass jars for example
the stopper is made with a hollow or cavity in its under side in which are placed any
suitable hygroscopic antiseptic or other agents suitable for preserving the contents of
the jar in good condition. A piece of cloth or other suitable permeable material is
placed over the opening of the cavity and may be conveniently secured in position
by placing the edges under a rubber packing ring or band which is lodged in a recess
formed in the circumference of the stopper for the purpose of making a tight joint.
This recess presents grooves or depressions for the reception of the edges of the
ring or band.
.
Canisters or tin boxes for example provided with covers arranged according to this
invention are preferably provided with a rubber ring lodged in a suitable recess or
corrugation formed (similarly to the recess in the stopper hereinbefore described) in
the sides of the box the cover being fitted to pass over the said ring and being provided
with an internal disc or flanged plate in such a manner as to form a chamber inside
the cover for the reception of the aforesaid hygroscopic, antiseptic or other preservative
agents. The interstices between the edges of the plate or disc and the sides of the
cover are sufficient to enable the said agents to act on the atmosphere in the box or
the plate or disc may be perforated a cloth or the like being laid over the perforations
to prevent the materials contained in the cover from falling through and the plate or
disc may be made to form a tight joint with the sides of the cover by the interposition
of packing or otherwise.

Improvements in Stoppers and Covers for Jars, Canisters, and other
like Vessels.
I JOHN HENRY JOHNSON of 47, Lincolns Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this invention which has been communi-
cated to me from abroad by Eugène Fournier of 48 rue de Bondy Paris in the
Republic of France Pharmaceutical Chemist 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 providing an hermetic closure for jars, canisters
and other like vessels which can be employed in combination with hygroscopic, anti-
septic or other preservative agents contained in a hollow or cavity provided for their
reception in the body of the stopper or cover. In the case of glass jars for example
the stopper is made with a hollow or cavity in its underside in which are placed any
suitable hygroscopic antiseptic or other agents suitable for preserving the contents of
the jar in good condition.
A piece of cloth or other suitable permeable material is placed over the opening of
the cavity and may be conveniently secured in position by placing the edges under a
rubber packing ring or band which is lodged in a recess formed in the circumference
of the stopper for the purpose of making a tight joint.
Canisters or tin boxes for example provided with covers arranged according to this
invention are preferably provided with a rubber ring lodged in a suitable recess or
corrugation formed (similar to the recess in the stopper hereinbefore described) in the
sides of the box the cover being fitted to pass over the said ring and being provided
with an internal disc or flanged plate in such a manner as to form a chamber inside
the cover for the reception of the aforesaid hygroscopic antiseptic or other preservative
agents. The interstices between the edges of the plate or disc and the sides of the
cover are sufficient to enable the said agents to act on the atmosphere in the box or
the plate or disc may be perforated a cloth or the like being laid over the perforations
to prevent the materials contained in the cover from falling through and the plate or
disc may be made to form a tight joint with the sides of the cover by the interposition
of packing or otherwise.
And in order that the said invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the several
figures on the annexed sheet of drawings the same letters of reference indicating
corresponding parts in both the figures.
Fig. 1 of the accompanying drawings represents a vertical section of a glass jar A
provided with a stopper B according to this invention.
The stopper which may also be made of glass is provided with one or more grooves❤
(two such grooves being shown in the figure) and a rubber ring e fits tightly into
these grooves and forming a tight joint with the mouth of the vessel retains the stopper

page_text: firmly in position in the mouth of the jar a shoulder e in combination with the grooves T
on the stopper preventing the ring from slipping off the latter.
The edges of a piece of cloth or other permeable material are clipped between the
ring c and the sides of the stopper and the preservative agents indicated at m are
retained in a cavity in the interior of the stopper by means of this permeable
material. The grooves for the reception of the packing ring or material making the
joint may be formed either in the sides of the stopper or in the sides of the vessel as
hereinafter explained.
Fig. 2 is a vertical section illustrating the application of the improved stopper or
cover to a tin canister A. The mouth or neck of the canister is provided with corru-
gations g corresponding to the grooves r in fig. 1 and serving to retain a rubber
packing-ring e in position upon the canister. In this case the ring c remains on the
canister or vessel A but it may be placed on corrugations formed on the stopper or
cover. The cover B is provided with a partition which may be retained in position
by friction alone and retains the preservative agents m in a chamber M in the interior
of the said cover. This partition may consist of a flanged disc or plate of perforated
metal and if necessary the perforations may be covered with woven fabric leather or
the like to prevent the materials m falling through the perforations. The partition may
be solid if preferred the interstices existing between the edges and the sides of the
stopper being sufficient to provide for the necessary communication with the interior
of the vessel and enable the materials m to absorb the moisture therein for example.
The edges of the cloth leather or other retaining material may be clipped between the
edges of the plate or partition and the sides of the stopper so as to retain even
pulverulent materials m in position in the chamber M and at the same time provide
for the necessary communication with the contents of the vessel.
The improved
stopper may be used without the preservative agents if required.
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. The improved tight fitting stoppers and covers with internal receptacle for the
reception of hygroscopic antiseptic or other preservative agents substantially as herein-
before described with reference to the accompanying drawings.
2. A tight fitting stopper or cover for jars canisters and other like vessels in com-
bination with hygroscopic antiseptic or other preservative agents suitable for main-
taining the atmosphere in the vessel in good condition for preserving the contents
thereof substantially as hereinbefore described.
3. The improved tight fitting stopper or cover for jars canisters and other like
vessels with or without materials suitable for preserving the contents of the said jars
canisters and other vessels substantially as hereinbefore described.
