Description
FIELD OF THE INVENTION
[0001] The present invention relates to devices for attachment to
bottles.
[0002] The invention is particularly applicable to devices such as
vacuum pumps and pourers used in the wine industry. However the
invention is equally applicable to other industries associated with
the supply of beverages.
BACKGROUND OF THE INVENTION
[0003] A typical bottle of wine utilises a cork to seal wine off
from the outside environment. Once the cork is removed from the
bottle, air is able to enter the bottle and aerate the wine. If it
is desired to store a bottle of wine which has already been opened
it is desirable to evacuate as much air as possible from the bottle
in order to preserve the wine. Devices which are useful in this
regard are called vacuum pumps and have a lower end which fits into
the mouth of the bottle. A finger operable pump is able to be
depressed repeatedly in order to evacuate air from inside the
bottle. Typically the lower end of the vacuum pump forms a seal
with the inner surface of the neck of the bottle once the lower end
of the vacuum pump is physically forced into the neck of the
bottle. The outer surface of the vacuum pump normally consists of a
series of ribs with O-rings located in the grooves between adjacent
ribs.
[0004] The problem with existing vacuum pumps is the requirement to
forcibly insert the end of the vacuum pump into the neck of the
bottle.
[0005] The present invention provides an alternative closure device
which in one embodiment may be used for a purpose other than a
vacuum pump.

DETAILED DESCRIPTION OF THE DRAWINGS
[0065] As shown in FIG. 1 a closure device in the form of a vacuum
pump 11 has a handle section 12 with a vacuum pump button 13
located on the top surface thereof. An attachment collar 14 is
shown at a lower end with a centrally located stopper 15 extending
proud of the lower end of the device 11. This is shown more clearly
in FIG. 2.
[0066] As shown in FIG. 3 the attachment collar 14 of the closure
device 11 consists of annular outer wall 16 separated from an
annular inner wall 17 by an annular groove 18.
[0067] The lower end of the outer annular wall 16 is in the form of
annular flange 19.
[0068] The inner surface 20 of the inner annular wall 17 is
provided with a screw thread which is configured to match the
external screw thread of the neck of a bottle 21 to which it is to
be attached.
[0069] The upper end of outer annular wall 16 tapers inwardly and
has an annular rib 22 located at the upper end of its inner surface
23.
[0070] The inner annular wall 17 is shorter in vertical length than
the outer annular wall 16 and has an upper limit 24 which is below
the level of the tapering wall 24.
[0071] The main body 25 of the device 11 includes the handle 12 and
a vacuum pump assembly 26. The lower mid section of the main body
26 is in the form of a collar 28 having an upper outwardly flaring
section 29 and a straight vertically extending lower section
30.
[0072] The lower end 31 of the lower section 30 is provided with an
external annular lip 31. As shown in FIG. 3 the straight section 30
fits into the annular groove 18 so that the inner wall 32 of the
straight section 30 abuts the opposing outer surface of the inner
wall 17 of the attachment collar 14. The outer surface 33 of the
straight wall 30 abuts with the inner edge of the annular rib
22.
[0073] The collar 28 may be integrally formed with a tubular
section 33 on which the handle 12 is mounted. Alternatively the
collar 28 may be attached to this tubular section 33.
[0074] The tubular section 33 forms part of the main body 27 and at
a lower mid section has a tapered stepped section 34 which extends
into a lower tubular section 35 of reduced internal diameter.
[0075] The stopper 15 is located around the external surface of the
second tubular section 35 and is provided to form a seal with the
inner surface of the neck of the bottle.
[0076] The lower tubular section 27 is divided into an upper
passage 36 and a lower passage 37. The upper passage includes a
lower valve 38 which sits below an upper valve component consisting
of a valve housing including an external O-ring which forms a seal
with the inner walls of the upper tubular section 33 and an inner
valve member 39. A central passage (not shown) extends from the
button 13 all the way down to the valve housing 38 and forms part
of a continuous passage through the device 11 into the lowermost
chamber of the lower passage 37.
[0077] In operation the attachment collar 14 is screwed onto the
neck of a bottle 21. In the process of screwing this collar 14 onto
the neck of a bottle the annular rib 22 engages the annular lip 31
thus pulling the whole of the main body 26 downwardly. This forces
the lower end of the main body into the neck of the bottle and
enables the tapered external surface of the stopper 15 to seal
against the inner surface of the neck of the bottle.
[0078] When the collar 14 is fully screwed onto the neck of the
bottle the device is properly attached. The button 13 can then be
repeatedly depressed in an operation similar to that of convention
vacuum pumps for wine bottles to withdraw air from inside the
bottle through the lower and upper passages 37 and 36 respectively
through the valve housing 38 up through the central passage and out
through an appropriately located air outlet. As air pressure
outside the bottle is greater than air pressure inside the bottle,
the lower valve 36 is normally engaged over the hole of the wall
separating the upper and lower passages 36 and 37.
[0079] With the above device it is relatively easy to attach a
vacuum pump to a bottle having an external screw thread.
[0080] It should be noted that the above embodiment can be attached
so that the inner screw thread of the inner wall 17 is replaced
with a series of inner ribs which allow attachment of the device to
a regular wine bottle without an external screw thread.
[0081] In other embodiments other internal surfaces may also be
used other than one with a screw thread.
[0082] It is also noted that when the collar 14 is screwed onto the
neck of a bottle, it is able to rotate relative to the main body 26
and the collar 28. This enables the vacuum pump lower end to be
easily inserted into the neck of a bottle without it having to
rotate at the same time as the external collar 14.
[0083] According to another embodiment of the present invention the
main body may incorporate a wine pourer instead of a vacuum pump.
The wine pourer may include a tubular device with a contoured
tongue to allow easy dispensing of liquid from the bottle. In such
an embodiment the handle 12 can be dispensed with and the tongue
would extend upwardly proud of the collar 28.
[0084] A closure device incorporating a wine pourer is shown in
FIGS. 4 to 7. Details of this device will be described
hereinafter.
[0085] As shown in FIG. 4 the pourer device 40 consists of a top 41
which is similar in design to the handle 12 of the first embodiment
described. At the lower end the pourer includes an attachment
collar 42.
[0086] Removal of the cap 41 reveals a pourer spout 43 extending
from a base surface 44 which flares outwardly and forms the upper
part of the collar 42. The base surface 44 includes a flat
horizontal partition wall 45 which separates the spout 43 from a
lower tubular section 46 which is provided with a sealing ring 47
at its lowermost end for forming a seal between the top of the
Stelvin bottle 48 shown and the rest of the pourer 40.
[0087] The base wall 44 which surrounds the spout 43 includes a
shoulder section 48 surrounding the spout 43. Above the shoulder 48
a small peripheral rib 49 is provided. This rib 49 engages with an
inwardly directed annular lip 50 at the bottom of the cap 41.
[0088] The top of the cap 41 is provided with a lid 51 which can be
designed as a flip top lid.
[0089] The attachment collar 42 consists of two parallel vertical
walls 52, 53 with the inner wall 51 having an internal thread to
allow it to be attached to a Stelvin bottle.
[0090] In use the wine pourer 40 is screwed onto a Stelvin bottle
by clasping the attachment collar 42 and screwing it onto the
Stelvin bottle. When it is desired to pour the contents of the
bottle either the cap 41 can be removed by disengaging the lip 50
from the rib 49 or alternatively the flip lid 51 can be lifted.
[0091] The base wall 45 is provided with an array of perforations
to assist with aeration of the fluid as it leaves the bottle.
[0092] The nozzle in the embodiment shown has the shape of a flared
tongue, but equally may have an alternative shape.
[0093] The closure device 60 shown in FIG. 8 has a cap 61, which in
contrast to the device shown in FIG. 7, is located within a sleeve
62. The shape of the sleeve 62 shown in FIG. 9 is generally
cylindrical with a bevelled flared opening which acts as the pourer
spout.
[0094] The sleeve and spout 62, 63 extend from attachment collar 64
which is similar in configuration to the attachment collar 42 in
FIG. 7. In addition however an aerator is welded to the attachment
collar 64 and is centrally located as referenced by item 65 in FIG.
8. The aerator 65 is seated at the bottom of the mouth of the spout
63.
[0095] Thus the embodiments of the invention shown in FIGS. 7 and 8
show how a cap can be incorporated which either fits over the
outside of the spout or nozzle or inside it.
[0096] It is also noted that in FIG. 8 the cap is provided with
sealing rings 66, 67 which may also be provided on an inner surface
of the cap 41 shown in FIG. 7.
[0097] It should further be noted that in the embodiment of the
invention shown in FIG. 3 an alternative embodiment is envisaged in
which the main body 26 has its lower cylindrical section configured
to fit inside the tubular section 33.
[0098] According to another variation of the present invention the
attachment collar shown in each of the devices may have a reverse
configuration with the screw-on section, for example annular flange
19, provided with an upwardly directed collar which fits into an
annular groove located at the lower end of collar 28. Thus the
collar 28 and attachment collar 14 interact in the same manner but
in a reverse configuration to that shown in FIG. 3. A similar
alternative embodiment is envisaged for each of the other devices
disclosed in FIGS. 7 and 8.
[0099] With regard to the aerator shown in FIG. 8, according to one
embodiment this consists of a circular disk with a series of
apertures therethrough and a downwardly directed central spigot
with a passage therethrough. This spigot fits into a tube extending
downwardly from the device and when the device is attached to a
bottle extends through the neck of the bottle to the interior. This
enables air flow/fluid flow through the tube via the hole in the
spigot as well as through the other holes which may be
concentrically arranged around a central hole co-terminus with the
passage through the spigot.
[0100] Thus in use if the device is attached to a wine bottle, wine
is able to be easily poured out through the device and the
arrangement of the holes and tubes attached to the spigot, assists
with aeration of the wine.
[0101] The concentric holes may be in the form of slanted radial
splits.
[0102] It is to be understood that, if any prior art publication is
referred to herein, such reference does not constitute an admission
that the publication forms a part of the common general knowledge
in the art, in Australia or in any other country.
[0103] In the claims which follow and in the preceding description
of the invention, except where the context requires otherwise due
to express language or necessary implication, the word "comprise"
or variations such as "comprises" or "comprising" is used in an
inclusive sense, i.e. to specify the presence of the stated
features but not to preclude the presence or addition of further
features in various embodiments of the invention.
