page_text: Improvements in Sealing Devices for Bottles, Jars, and other Vessels.
I, ACHILLE WEISSENTHANNER, of 168, Rue St. Maur, Paris, in the Republic
of France, do hereby declare the nature of this invention to be as follows;
This invention relates to improvements which I have devised in sealing devices
for bottles, jars and other vessels, which comprise the employment of a ring sup-
ported above upon the metallic lid and of which the lower edge is pressed beneath
the shoulder or fillet of the vessel. These improvements will be readily under-
stood from the following description.
The neck of the bottle or flask is provided with a shoulder or fillet having at its
upper portion a circular projection as in the case of certain methods of sealing
already in use, in addition to this, and this is an essential feature of the invention,
this fillet has upon its external vertical edge a projection, the object of which is
to ensure the pressing under or setting of the closing ring without its being pos-
sible for this latter to crease as is the case with the method hitherto employed.
According to one form. of my invention the sealing is effected by placing first
of all upon the top of the neek of the vessel a thin sheet of pure tin, then an india
rubber, cork, or other elastic washer, and finally a rigid metallic capsule, after
which a ring is placed in position, the upper edge of which rests upon the capsule.
In this case it will be understood that the operation of the pressing under or set-
ting of the lower edge of the ring beneath the fillet of the neck takes place without
the possibility of creasing on the part of the said ring. The said ring bears
effectively at this point laterally upon the circumferential projection of the fillet.
This is not the case when the external circumference of the fillet is cylindrical,
because in this case the excess of thickness formed by the falling edge of the cap-
sule leaves beneath this edge, around the glass of the fillet a space the thickness
of which is at least equal to the thickness of the metal of the capsule, in such a
manner that the fixing ring is not completely fixed in position at its lower por-
tion and is able to crease.
The improved sealing may be applied to a vessel having a spherical bottom and
adapted to contain truffles.
The advantages of the projection on the circumferential face of the fillet or
shoulder are very considerable with bottles of small dimensions.
According to another modification the upper portion of the bottle may also be
provided with a recess into which a projection on the capsule will force the tin
under the pressure exerted by the pressing of setting operation.
It is obvious that the height of the lateral projection of the fillet or shoulder
and also that of the falling edge of the capsule will be such that after sealing
has been effected that is to say after the lid has had strong pressure applied to it
and the ring has been pressed under or set the falling edge of the capsule will
not touch or barely touches the top of the said lateral projection.
This method is equally applicable to vessels of which the fillet or shoulder of
the neck is not provided with a projection upon its upper face and also to vessels
which comprise below the top of the neck a shoulder upon which rests the edge

of the capsule and the upper edge of the pressed fixing ring. In a bottle of this
kind the upper face of the neck is absolutely plane, and on the other hand this
fillet is provided with a shoulder or projection upon which the upper edge of the
ring bears.
This bottle is closed in the same manner as in the preceding example, prefer-
ably with a washer of pure tin, a washer of flexible or elastic material and a rigid
metal capsule, the edge of which is shaped in such a manner as to fit upon the
upper portion of the neck so as to bear upon the shoulder. When the capsule
has been placed in position, and pressed beneath the fillet or set, it bears, as in
the preceding case, upon the external projection and also upon the circumference
of the capsule; this ring being well supported laterally is not able to crease.
According to another method of scaling bottles, flasks or other vessels by means
of a pressed ring, the said bottle or vessel is formed with a fillet or shoulder
leaving above it a recessed portion the profile of which is slightly inclined. The
purpose of this inclination will be understood from the description which follows.
In order to effect the sealing, a capsule is placed in position; the falling edge of
this capsule presents a small flat horizontal band or flange which rests upon the
top of the fillet. There is placed around this capsule resting upon the small edge
or flange of the same, an india rubber ring and finally the circular ring is applied.
Strong pressure is exerted upon this latter in order to finally press under or set
the lower edge of the same beneath the fillet.
Under the action of the pressure exerted by the ring, the india rubber being
strongly compressed will force the falling edge of the capsule into the oblique
angled recess formed upon the fillet, whilst at the same time this india rubber
strongly presses the flat edge or flange of the capsule upon the fillet and makes
a joint with the glass, the india rubber spreads still further in an upward direc-
tion, between the upper edge of the ring and the falling edge. In this manner
an absolutely tight sealing is obtained whilst the india rubber is entirely removed
from contact with the contents of the vessel.
This method of sealing is especially adapted for the sterilisation of milk; in
this case the capsule (for the purpose of enabling ebullition to take place freely)
is pierced with a capillary orifice, through which the heated air escapes; as is
well known, this small aperture is closed when desired by means of a bead of
solder. If the metal of which the lid is formed is malleable, the aperture may be
closed by means of a pliers.

Ny ward, and other vessels.
I, ACHILLE WEISSENTHANNER, of 168, Rue St. Maur, 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 relates to improvements in sealing devices for bottles, jars and
other vessels, which comprise the employment of a ring supported above
metallic lid and of which the lower edge is pressed beneath the shoulder or fillet
upon the
of the jar or vessel.

page_text: These improvements will be readily understood from the following description
reference being had to the accompanying drawings.
Figure 1 shews the neck of a bottle or flask which is provided with a shoulder
or fillet having at its upper portion a circular projection a as in the case of cer-
tain methods of sealing already in use, in addition to this, and this is an essential
feature of my invention, this fillet has upon its external vertical edge a projec-
tion b, the object of which is to ensure the pressing under or setting of the closing
ring without its being possible for this latter to crease as is the case with the
method hitherto employed.
According to the form of my invention illustrated in Figure 2 the sealing is
effected by placing first of all upon the top of the neck of the vessel a thin sheet c
of pure tin or other suitable material, then an india rubber, cork, or other elastic
washer d, and finally a rigid metallic capsule e, after which a ring B is placed in
position, the upper edge of which rests upon the capsule. In this case it will be
understood that the operation of the pressing under or setting of the lower edge
of the ring B beneath the fillet A of the neck (see Figure 3) takes place without
the possibility of creasing on the part of the said ring B; the said ring bearing
effectively at this point laterally upon the circumferential projection of the fillet b.
This is not the case when the external circumference of the fillet is cylindrical,
because in this case the excess of thickness formed by the falling edge of the
capsule e leaves beneath this edge, around the glass of the fillet a space, the thick-
ness of which is at least equal to the thickness of the metal of the capsule, in such
a manner that the fixing ring B is not completely fixed in position at its lower
portion and is therefore liable to crease.
The improved sealing may be applied to a vessel having a spherical bottom and
adapted to contain truffles as shewn in Figure 3.
The advantages of the projection 6 on the circumferential face of the fillet or
shoulder are very considerable with bottles of small dimensions, and more
especially in the case of bottles such as that shewn in Figure 4.
In the construction shewn in Figure 5 the upper portion of the bottle may also
be provided with a recess into which a projection d on the capsule f will force
down the tin under the pressure exerted by the pressing or setting operation.
It is obvious that the height of the lateral projection of the fillet or shoulder
and also that of the falling edge of the capsule e will be such that after sealing
has been effected that is to say after the lid has had strong pressure applied to it
and the ring has been pressed under or set the falling edge of the capsule e will
not touch or barely touch the top of the said lateral projection b.
This method is equally applicable to vessels of which the fillet or shoulder of
the neck is not provided with a projection a upon its upper face and also to vessels
which comprise below the top of the neck a shoulder upon which rests the edge
of the capsule and the upper edge of the pressure fixing ring. In a vessel of this
kind which is represented in Figure 6 the upper face of the neck is absolutely
plane, as shewn at g, and on the other hand this fillet is provided with a shoulder
or projection upon which the upper edge of the ring bears.
When
This bottle is closed in the same manner as in the preceding example, prefer-
ably with a washer c of pure tin or the like, a washer of flexible or elastic mate-
rial and a rigid metal capsule e, the edge of which is shaped in such a manner as
to fit
upon the
upper portion of the neck so as to bear upon the shoulder h.
the capsule has been placed in position, and pressed beneath the fillet as shewn
in Figure 8, it bears, as in the preceding case, upon the external projection b
and also upon the circumference of the capsule e; and this ring being well sup-
ported laterally is prevented from creasing.
The remaining figures of the drawing represent another method of sealing
bottles, flasks or other vessels by means of a pressed ring, the said bottle or vessel
is in this case formed with a fillet or shoulder A leaving above it a recessed por-
tion , the profile of which is slightly inclined, as shewn in Figure 9, the purpose
of which inclination will be hereinafter described. In order to effect the seal-

page_text: ing, a capsule is placed in position; the falling edge of which presents a small
flat horizontal band or flange m which rests upon the top of the fillet A (see
Figure 10). There is placed around this capsule and resting upon the small
edge or flange m of the same, an india rubber ring and finally the circular
ring B. is applied. Strong pressure is exerted upon this latter in order to finally
press under or set the lower edge of the same beneath the fillet A, as shewn in
Figure 11.
;
Under the action of the pressure, exerted by the ring B, the india rubber ring n
being strongly compressed will force the falling edge of the capsule 7 into the
oblique angle recess formed upon the fillet A whilst at the same time the india
rubber ring strongly presses the flat edge or flange m of the capsule upon the
fillet A and makes a joint with the glass, the india rubber spreading still further
in an upward direction between the upper edge of the ring B and the falling edge.
In this manner an absolutely tight sealing is obtained, whilst the india rubber
is entirely removed from contact with the contents of the vessel.
This method of sealing is especially adapted for the sterilisation of milk; in
this case the capsule/ (for the purpose of enabling ebullition to take place freely)
is pierced with an orifice o through which the heated air escapes; as is well
known, this small aperture is closed when desired by means of a bead of solder p:
If the metal of which the lid is formed is malleable, the aperture may be closed
by means of a pliers or the like.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. In sealing devices for bottles, jars and other vessels the arrangement of the
external surface of a fillet formed on the vessel below which is effected the setting
of an external ring having a circular projection above which engages the descend-
ing edge of a closing capsule, and which itself serves as a lateral point of support
for the lower portion of the said ring and prevents it from creasing during the
operation of setting, this device being adapted for application upon jars in which
the upper surface of the neck is entirely plane or in which the neck is provided
with a circular shoulder or finally with one or more grooves, substantially as
above described.
2. The sealing of bottles, jars or other vessels with a ring which is pressed under
or set and supported upon the horizontal edge of a capsule by means of an india
rubber ring upon which the pressed under ring bears, the pressure received by
the india rubber and transmitted by it to the circumference of the capsule serving
to force the metal into an angular part formed with an oblique face, thereby
effecting an absolutely hermetic sealing, the pressure being similar to that pro-
duced by a wedge forced into a recess having an inclined face, substantially as
above described.
