IMPROVEMENTS IN EXTERNAL SCREW STOPPERING FOR BOTTLES
Year: 1885

page_text: I EDWARD EDEN HANSLOW of the Atlas Glass Works, Harriett Road Glengall
Road, Old Kent Road, in the County of Surrey, Glass Bottle Manufacturer do
hereby declare the nature of my invention for IMPROVEMENTS IN EXTERNAL
SCREW STOPPERING FOR BOTTLES "to be as follows:-
68
This invention relates to certain improvements in external stoppering of bottles.
In carrying the invention into practice a screw thread is made on the external
portion of the neck of the bottle so as to engage with a screw cap or stopper and
said screw thread is to be formed on the neck of the bottle so as to leave a short
length of the top portion of the neck plain; that is with the screw below it, said
top portion of the neck may be ground or not.
The cap or stopper employed has an internal screw thread formed therein and.
a central plug portion of size sufficient to allow of the said plug to enter the bottle
mouth and said plug may be screwed or plain as required and the internal plug of
the stopper whether plain or screwed may also receive a packing more or less for
corking the bottle.
Within the said cap a washer or seating of cork or packing material will be
provided against which the upper extremity of the neck of the bottle will abut
when the bottle is stoppered by screwing on the cap. This will form a very
effective stoppering for malt and fermented liquors, aerated waters and so forth.
I am aware that an external screw cap or stopper has been used before but the
claim will be to stoppering as herein specified.

I, EDWARD EDEN HANSLOW, of the "Atlas" Glass Works, Harriett Road, Glengall
Road, Old Kent Road, in the county of Surrey, Glass Bottle Manufacturer, do
hereby declare the nature of my said invention for "IMPROVEMENTS IN EXTERNAL
SCREW STOPPERING FOR BOTTLES," and in what mannor the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
This invention relates to certain improvements in external stoppering of bottles.
In carrying the invention into practice a screw thread is made on the external
portion of the neck of the bottle so as to engage with a screw cap or stopper and
said screw thread is to be formed on the outside of the neck of the bottle so as to
leave a short length of the top portion of the neck plain that is with the screw
below it, said top portion of the neck may be ground or not.
The cap or stopper employed has an internal screw thread formed therein and
a central plug portion of size sufficient to allow of the said plug to enter the bottle
mouth and said plug may be screwed or plain as required; within the said cap
a washer or seating of cork or packing material will be provided against which
the upper extremity of the neck of the bottle will abut when the bottle is stoppered
by screwing on the cap, and the internal plug of the stopper whether plain or
screwed may also receive a packing more or less for corking the bottle. This will
'form a very effective stoppering for malt and fermented liquors, aerated waters
and so forth.
:
In the following more particular description reference will be made to the
accompanying sheet of drawings, wherein Fig. 1 is a sectional view of an improved
screw stoppering cap constructed according to this invention.
Fig. 1 showing in section the upper part of a bottle neck to which the stopper
is intended to be applied; and Fig. 2 is a sectional view showing the said stopper
cap in position when screwed down.
Figs. 3 and 3 are like views showing a modification of the invention, and Figs. 4
and 4° show a further modification thereof.
It will be seen upon reference to Figs. 1, 2, 3 and 3* of the drawings, that the
cap a is constructed with a central plug stopper 6 the side surface of said plug
being ground or otherwise made to fit tightly within the bottle neck c and that an
internal screw thread a¹ is formed around the interior of the cap a for securely
fastening saine down on to the bottle by screwing the same upon the external screw
thread formed around and upon the bottle neck to receive it.
.
For the purpose of securing a perfectly close junction of the cap with the bottle
the screw thread so formed within the cap a extends only to a portion of the
depth of its interior so leaving an unbroken surface d for a part of the internal
side surface of the cap, and the external screw upon the bottle is formed at a
corresponding depth below the upper edge of the neck thereby leaving a similar
unbroken surface d' around the outside of the neck and upon which the portion d
of the cap a will bear when in place.
The top surface e of the neck of the bottle and the head e¹ of the annular space
formed within the cap a around the plug b will be ground true so as to make tight

page_text: joint when the two parts are brought in contact and the portion of the side
surfaced within the cap a-and the corresponding portion around the outside of
the bottle neck will be similarly treated. The aforesaid portions d and d¹ of the
cap and of the bottle neck may be parallel or tapered as may be convenient and
the plug b and the internal upper part of the bottle neck c may also be either
parallel or conical correspondingly as desired.
In the modification shown in Figs. 3 and 3" The cap a is provided with a ring
or washer fof rubber cork, or other suitable material fitted within the head of the
annular space el formed within the cap a and around the plug b whereby when
the cap is screwed down upon the bottle the washer f will form a yielding seat or
cushion between the cap and the bottle neck and will thus make a very tight joint
and effectually prevent any escape of the contents of the bottle.
A further modification of the invention is shown in Figs. 4 and 4" wherein the
plug b of the cap a is made somewhat smaller in diameter than the orifice of the
bottle neck c said plug b being provided with a screw thread b¹ upon which there
is fitted a ring or washer or sleeve piece g of rubber cork or other suitable material
which whilst adhering firmly to the plug b and by the elasticity fit closely within
the bottle neck so serving to make tight joint when the cap is screwed down and
which will not become detached from the plug b when the cap is removed from its
place on the bottle.
The screw of the cap as shown with several convolutions may be taken as
indication only as one or more such convolutions would for most cases suffice.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be carried into effect I declare that
what I claim is
The improvements in external screw stoppering with internal plug fitted and
operating as and for the purpose herein set forth in reference to and shown by the
drawings Figs. 1, 1ª, and 2, 3 and 3, and 4 and 4".
