PROVISIONAL SPECIFICATION.
Improvements in Stoppering or Olosing Jars, Bottles, and
the like.
I, PIERRE PHILIP, of 36, Rue du Mont-Thabor, Paris, in the Republic: of
France, Manufacturer, do hereby declare the nature of this invention to ibe as
follows:-
My invention relates to a system of stoppering or closing jars, bottles and like
vessels such as are used to contain preserved food..
According to my invention I employ a cap or cover designed to be placed over
the neck or mouth of the jar or bottle, a tight joint being produced by lining the
interior of the cap or cover and the exterior of the neck of the jar or bottle with
an elastic or flexible material, for example, cork against cork, cork against-india-
rubber, or india-rubber against india-rubber.
The mouth of the vessel may be formed slightly conical to receive and retain a
slightly conical cork ring, an india-rubber wasber being placed in a groove in a
flange on the neck below the said ring so as to form a soft and yielding seat for the
ring, the interior of the cap or cover being provided with a cork ring so that when
the cap is applied to close the vessel the latter ring is pressed against the conical
ring on the mouth. The cap or cover may be provided with a flange corresponding
with the flange on the neck of the vessel, the two flanges being fastened together
by a ring, clips, screws or other suitable means.
Or the conical mouth of the vessel can be fitted with a rubber ring of triangular
section so that when the cap is placed over the mouth its interior ring will easily
apply itself without the rubber offering any appreciable resistance. The stoppering
will become more and more secure as the cap is passed over a larger part of the
rubber ring.
In some cases the rubber ring is applied over a bead or beads on the mouth of
the vessel, and the cap or cover may be made of thin flexible sheet metal so that it
will adapt itself under pressure to the form of the covered bead or beads.
To cause a cap of this description to so adapt itself to the form of the mouth of the
vessel, I make use of a ring which being forced over the cap will cause the top edge
thereof to contract and, consequently, the sides to press closely against the rubber
ring, thereby producing a tight joint.

COMPLETE SPECIFICATION.
Improvements in Stoppering or Closing Jars, Bottles, and
the like.
I, PIERRE PHILIP, of 36, Rue du Mont-Thabor, Paris, in the Republic of
France, 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
0 in and by the following statement :-
My invention relates to, a system of stoppering or closing jars, bottles and like

page_text: vessels such as are used to contain preserved food, and in which the outside of the
Deck or mouth of the vessel is provided with a ring of elastic material, such as
india rubber and with a cover fitting over the same. This cover may be made of
glass, earthenware, porcelain, terra-cotta, stone, metal or other suitable material
and be lined with a collar or ring of cork in such a manner that the closure shall
he effected between two elastic substances and consequently be hermetic.
Or I can employ as a cover a thin metal cap or the like the edge of which can
yield under the action of a ring forced down over its periphery, the pressure thus
exerted causing a hermetic closure, owing to the interposition of the india rubber
ring.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing, in which :-
Figure 1 is a section of the cap or stopper provided with an inner lining
of cork.
Figure 2 is a section of the neck of the jar or vessel having an outer cork
ring:
Figure 3 is a section shewing the two parts connected.
The neck A of the jar the exterior of which is by preference slightly conical,
that is to say, decreasing in size from the top downwards, is provided with a cork
ring a; if required an india rubber washer 6 can be interposed in a small recess in
the flange or collar B of the jar to deaden the contact of the two parts against each
other. The cap or cover C is provided with an inner ring c of cork which when
closing the jar presses tightly over the ring a of the neck owing to the ring a being
slightly conical, as shewn in Figure 3.
The cap or cover has a rim or flanged the face of which when the jar is closed
comes against the face d' of the flange B and these two flanges can be connected by
a ring, a clip, screws or other suitable means.
Figures 4, 5 and 6 respectively represent a modification in which the neck of the
jar is provided with an india rubber ring.
The neck A of the jar is formed on the outside with a portion widened from
below upwards so as to constitute a retaining surface for the india rubber ring a
serving to make an hermetically tight joint with the cap or cover. This india rubber
ring a, which is cemented, or not, to the neck, is of the shape shewn in the drawing;
it is of triangular section and one of the edges or angles lies uppermost so that the
cap or cover can be easily applied without the india rubber offering any appreciable
resistance. As the cap or cover is forced down over a larger part of the india
rubber ring the tightness of the closure will become proportionately greater.
The cap or cover C of glass or other material is lined inside with a cork ring c
secured by cement or otherwise; it is designed like the cork ring of the preceding
arrangement, to make a tight joint against the india rubber ring a with which the
outside of the neck of the jar is provided.
Figure 7 is a modification in which a thin india rubber ring a is applied around a
projecting bead or convexity e on the neck of the jar. I can employ if required
several of these projecting beads or convexities.
Figure 8 is a section shewing the neck of a jar provided with an india rubber
ring a as in Figure 7 and over which a metal cap is applied. This india rubber
ring a in the form of a very thin collar is applied to the periphery of the bead or
convexity e, on the neck A of the jar. It is preferably rendered adherent to the
neck by means of glue, varnish or the like.
Over this neck is placed a thin metal cap D capable of adapting itself upon the
application of outward pressure to the exact conformation of the jar or vessel to be
closed or stoppered.
.
Figure is a section shewing this jar with bulging india rubber ring covered with
the thin metal cap.
To close the jar it is only necessary to force the ring E over the periphery of the
metal cap, which, as shewn in Figure 10, will thereby be compressed and caused to

page_text: assume the convex form of the neck of the jar whereby an absolutely hermetical
closure is ensured.
Figure 11 shews a jar, the neck of which has two beads or convexities e both
covered with india rubber; I can as already stated employ several of the said beads
or convexities.
Instead of forming jars or vessels with convexities on the neck as herein before
described and illustrated in Figure 11 I may make the jars or vessels with plain or
smooth necks as shewn in Figure 12. In this case I cement a ring of india rubber
or other suitable elastic material on the neck or I roughen the neck of the jar, by
subjecting it to the action of hydrofluoric acid, and then spread thereon a solution
of india rubber so as to form a ring of sufficient thickness, which can be vulcanised
in the usual manner.
This india rubber ring may be if necessary formed conical to ensure a tight joint
when the outer ring is forced on.
Figure 13 shews an elevation partly in section of my invention applied to the
closing of preserve jars.
The top A of the jar is formed with a bead e around which is fixed an india
rubber collar or ring a. Over this ring a thin metal capsule D is placed and the
joint is completed by forcing on the ring E which may be provided with a tongue
for stripping off the ring E when opening the jar.
The ordinary cover F of the jar can then be put on in place.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A system of stoppering or closing jars, bottles and like vessels, of glass,
porcelain or other material, by means of a cap or cover designed to be placed over
the neck or mouth of the jar or bottle, a tight joint being produced by lining the
interior of the cap or cover and the exterior of the neck of the jar or bottle with an
elastic or flexible material, such for example as, cork against cork, cork against
india rubber, or india rubber against india rubber, substantially as herein before
described and illustrated in Figures 1 to 12 of the drawing.
2. A system of stoppering or closing jars, bottles and like vessels consisting in
introducing between the neck of the jar and the inner periphery of a flexible
metal cap, a thin ring of india rubber, cork or other elastic material applied with
or without cement over one or several beads or convexities upon the neck in such a
manner as to cause a tight joint upon the application of a ring forced over the
periphery of the flexible metal cap, substantially as hereinbefore described and
illustrated in Figures 1 to 12 of the drawing.
3. The application of my system to the stoppering or closing of preserve jars as
hereinbefore described and illustrated in Figure 13 of the drawing.
