I DANIEL GALLAFENT of 3 Market Hill, South Woolwich, in the County of
Kent, Engineer do hereby declare the nature of my invention for "IMPROVE-
MENTS IN BOTTLES AND LIKE RECEPTACLES AND IN THE STOPPERS THEREFOR
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :—
.
My Invention consists in so forming the interior of the neck of bottles and like
receptacles such for instance as are used for potable effervescent fluids or fluids
charged with gases under pressure-and in the employment in conjunction there-
with of such a stoppering device as shall allow of the convenient .delivery or
decanting of any desired portion of the contents without the necessity for removing
the stopper and at the same time,-as by; means of my Invention any undue
escape of gas or diminution of effervescent power is prevented, the contents retain
their full briskness and exhilarating properties unimpaired as long as any portion
thereof remains in bottles or receptacles constructed and stoppered in accordance
with my Invention.
In carrying out my Invention I proceed as follows:-reference being had at the
same time to the accompanying sheet of drawings. That is to say.-The interior
of the neck of the bottle is formed as shewn at a, with a series of coarse pitched
female screw threads. The neck of the bottle is formed as shewn at b with an
annular recessed seating on to which is fitted a washer c of caoutchouc, cork or
other suitable cushioning material to receive the lower end d of the improved
stopper bereinbefore referred to.-The body of said stopper is formed as shewn at e
with an external male screw thread which takes into the female screw a aforesaid,
formed in the interior of the neck of the bottle.-In the act of stoppering or
sealing the bottle or other receptacle, an annulus, ring or washer ƒ formed of
similar material to that described in reference to the washer c aforesaid, is intro-
duced under the cap or head g of the stopper and the top h of the neck of the
bottle. Said washer fit will be noticed on reference to the vertical sectional view
Figure 2; is, in its normal or uncompressed state, of increased depth to the lower
washer c. The washer f, arranged as above described, acts as a valve whereby any
leakage is prevented when the stopper is released from the lower seating 6 The

of the stopper from the lower seating aforesaid, is readily effected by simply
turning round to the desired extent, the cap g.
Further, I form centrally and vertically, extending from the top or cap g of the
stopper to within a short distance of the lower extremity thereof, a cylindrically
shaped passage i which enters into and communicates with the lateral passages k
which radiate from the central vertical passage i, to the outside, d, of the lower
plain part of stopper, as shewn more particularly in the vertical section Figure 2,
and by dotted lines in the plan view (looking on top of stopper) Figure 3.
When discharging or decanting off any desired portion of the contents of a bottle
and provided with stoppering device according to my Invention (the improved
stopper aforesaid being then released from contact with the lower washer, pad, or
collar c aforesaid, and the bottle being held in an inverted position), the fluid
passes now above c, enters,-by means of the laterally arranged ducts or
passages k, into and passes up the central passage i to the top of the stopper
cap g, and is discharged or delivered there through; the within contained gas
being, during this operation behind the fluid contents which are being delivered or
discharged, as aforesaid Said delivery, discharge or flow is, when desired, at once
stopped, by the simple act of screwing the stopper down, and "home" on to the
washer or pad in the seating b.
From the foregoing description it will be seen that any desired portion of the
contents of a bottle as herein before described may be withdrawn without removing
the stopper from the bottle. Similarly also the filling of the bottle may, if desired,
be accomplished without removing the stopper, the vertical passage i and lateral
passages being utilised for said purpose.
Referring to the top collar f hereinbefore mentioned; it may be stated that this
would serve a further purpose of utility, owing to its property of resilience serving
to prevent accidents in cases of sudden concussion from impact of anything falling
on the top of bottles so stoppered.
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:
First. The recess b, with washer c as and for the purposes herein described.
Secondly. The improved stopper substantially as herein described with passages
therein as and for the purposes substantially as set forth.
Thirdly. The top collar or washer f acting as a valve, for the purposes herein set
forth.
