PROVISIONAL SPECIFICATION.
An Improved Bottle Screw Stopper for Stopping or Corking Mineral
Waters and other Gaseous or Non-gaseous Liquids, Beer, Stout,
and the like.
J, LEON VALLET, of 49 Everton Road, Liverpool, in the County of. Lancaster,
Bottle Stopper Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention has reference to stoppers of the screw type, that is stoppers which
are provided with a few turns or threads, and which engage in corresponding
threads in the interior surface of the neck of bottles, and in which a liquid or gas
tight joint is effected between the stopper and the neck or upper edge of the neck
of the bottle, by a collar or washer of india-rubber, round the shank of the stem or
screw of the stopper, and under the head or cap of the stopper, the purposes for
which such stoppers are applicable, and it is generally intended to use them in
connection with, being. for the closing or stopping or corking of mineral waters,
and other gaseous or non-gaseous liquids, beer, stout, and the like.
A stopper according to this invention has on the under side of the head or cap
of the stopper round the shank, a recess extending up into such head, and into
this recess or groove, the upper edge of the rubber washer fits, so that when in
place it cannot be disturbed, that is pressed out or removed from its proper position
by pressure due to gas, or that caused by, screwing the stopper tightly into the
bottle. In screwing my stopper into a bottle mouth, when the india rubber comes
f contact with the upper edge thereof, the tendency is to force the rubber ring
slightly into the groove or recess; and therefore this pressure not only does not
tend to press or force the rubber washer out of its proper position, but tends to hold
it in its position, and prevent it from bulging out of its seat. In consequence,
leakage due to the displacement of a part or a whole of the washer is avoided, and
besides, it affords help to the keeping of the rubber ring or washer in its place
when opening the bottle.
In stoppers of the kind herein referred to as hitherto made, pressure upon the
ring in screwing in the stopper, or that due to the pressure within the bottle,
frequently causes the upper part of the india rubber ring or washer to bulge out of
place at parts, or all round, the result being a leakage from the bottle, and in many
cases the spoiling of its contents; ny improved stopper above described obviates,
as above stated, these defects and results, and provides a means of stopping of
bottles containing liquid such as specified, which is both effectual for the purposes
intended, and not liable to derangement or defective action under any normal
conditions.

An Improved Bottle Screw Stopper for Stopping or Corking Mineral
Waters and other Gaseous or Non-gaseous Liquids, Beer, Stout,.
and the like.
I, LEON VALLET, of 49 Everton Road, Liverpool, in the County of Lancaster,.
Bottle Stopper 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 :-
This invention has reference to stoppers of the screw type, that is stoppers which
are provided with a few turns or threads, and which engage in corresponding
threads in the interior surface of the neck of bottles, and in which a liquid or gas
tight joint is effected between the stopper and the neck or upper edge of the neck
of the bottle, by a collar or washer of india-rubber, round the shank of the stem or
screw of the stopper, and under the head or cap of the stopper, the purposes for
which such stoppers are applicable, and it is generally intended to use them in
connection with, being for the closing or stopping or corking of mineral waters,
and other gaseous or non-gaseous liquids, beer, stout, and the like.
A stopper according to this invention has on the under side of the head or cap of
the stopper round the shank, a recess extending up into such head, and into this
recess or groove, the upper edge of the rubber washer fits, so that when in place it
cannot be disturbed, that is pressed out or removed from its proper position by
pressure due to gas, or that caused by screwing the stopper tightly into the bottle.
In screwing my stopper into a bottle mouth, when the india-rubber comes in
contact with the upper edge thereof, the tendency is to force the rubber ring
slightly into the groove or recess; and therefore this pressure not only does not
tend to press or force the rubber washer out of its proper position, but tends to
bold it in its position, and prevent it from buiging out of its seat. In consequence,
leakage due to the displacement of a part or a whole of the washer is avoided, and
besides, it affords help to the keeping of the rubber ring or washer in its place
when opening the bottle.
In stoppers of the kind herein referred to as hitherto made, pressure upon the
ring in screwing in the stopper, or that due to the pressure within the bottle,
frequently causes the upper part of the india-rubber ring or washer to bulge out of
place at parts, or all round, the result being a leakage from the bottle, and in many
cases the spoiling of its contents; my improved stopper above described obviates,
as above stated, these defects and results, and provides a means of stopping of
bottles containing liquid such as specified, which is both effectual for the purposes
intended, and not liable to derangement or defective action under any normal
conditions.
The drawing hereto annexed shews the stopper according to this invention, in
section.
Referring to the drawing, a is the head of the stopper, which is of the usual kind,
and by means of which the stopper is screwed into and out of the neck of the
bottle; and b is the threaded or screw shank of the stopper. c is the india-rubber
washer which fits upon or over the shoulder d of the shank, while its upper edge fits
into the annular groove or recess at e turned in the head a of the stopper. is the
neck of the bottle, shewing the position the stopper takes in the bottle neck when
screwed in and properly stoppered.
By this illustration, it will be seen how the effect above referred to is accom-
plished. That is to say, it will be seen, that when the stopper is screwed down
into the neck of the bottle, and the rubber washer c is pressed down onto the

page_text: ordinary somewhat tapered neck, the tendency, in the case of ordinary stoppers of
this kind, particularly when much pressure is applied, will be to squeeze the upper
edge of the washer (which would simply abut on the underside of the overhanging
edge of the stopper head) out of place, and between the bottle neck and the
stopper head; but, by the present construction, by this upper edge of the washer
being seated in the annular recess of the head, at e, it is impossible that it can be so
displaced or pressed out of position..
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 :-
The herein described improved screw stopper, comprising the head a, the
threaded shank b, washer c, and annular recess or groove e, in which the upper
edge of lies as herein set forth and shewn in the drawing.
Dated this 18th day of December 1896.
