Description
A CORK REMOVER FOR A BOTTLE CONTAINING SPARKLING LIQUID.
FIELD OF THE INVENTION
The present invention relates to a cork remover for a bottle containing sparkling
liquid.
BACKGROUND OF THE INVENTION
It is commonly known that bottles containing sparkling liquid and closed by a cork,
e.g. champagne bottles, are under high pressures up to almost 7 bars.
Consequently, accidents happen on a regularly base by corks becoming
uncontrollable projectiles upon opening the bottle. Such expelled cork can be very
dangerous and harmful for the consumer’s face and in particular the eyes.
In the state of the art, several attempts are made to avoid such dangerous situations.
For example, WO2006092661 (Mauffette) describes a cork remover where relative
rotation causes cork-gripping means to exert an upward action on the cork. The cork
is thus lifted upwardly until it is finally expelled from the bottle under the action of the
pressure inside the bottle and wherein the expelled cork is trapped in a space
provided in the cork remover decreasing in cross sectional area in the direction of
cork expelling direction.
Another example is WO2008061547 (Ferrari) describing a cork remover with an outer
body engaging on the bottle neck bulge and an inner body engaging on the cork. The
inner body is slidably mounted in the outer body such that it slides upwardly when the
cork is expelled.
However, besides the fact that the last cited cork remover is quit complex in
manufacturing and in use, a remaining problem of all above cork removers is that,
although the cork is trapped by the cork remover, the safety harness still has to be
removed from the bottle neck bulge before positioning the cork remover. As a
consequence, the risk remains that the cork will be accidentally expelled before
placing the cork remover.
In an attempt to solve the above problem, US4,750,391 describes a cork remover
having a frame with pivotable annulus for placing the cork remover over the cork and
the safety harness, and a pair of thongs connected to a pair of arms for lifting the
cork.
A disadvantage of this type of cork remover is its complexity in manufacturing the
parts and in assembling.
Another disadvantage is that a user needs two hands for engaging the handles such
that he is compelled to provide a stable, horizontal, un-slippery surface for placing
the bottle on.
A second remaining problem is that state of the art cork removers are not adapted to
withstand the lifting pressure on the cork in the last phase of the opening process. As
a result, the consumer cannot avoid that the cork is expelled abruptly in the last
phase of the opening process. As is commonly known, the quality of for example
champagne is decreased by brutal cork expel because then the pressure in the bottle
drops abruptly and the carbon dioxide concentration in the liquid decreases to much.
Considering the above drawbacks, it is a first object of the present invention to
provide a cork remover adapted to trap the expelled cork.
It is a second object of the present invention to provide a cork remover for which it is
not required to remove the safety harness from the bottle neck bulge before
positioning the cork remover.
Further, it is a third object of the present invention to provide a cork remover having
the ability to controllably release the cork, even in the last phase of the opening
process, such that the genuine quality of the sparkling liquid can be kept.
Another object of the present invention is to provide a cork remover which is less
complex in manufacturing and less complicated in use.
The present invention meets the above objects by providing a cork remover
comprising an outer body, and an inner body having cork-gripping means and being
slidably mounted in the outer body, characterized in that the outer body comprises a
notch for positioning the outer body over a bottle cork’s safety harness and releasing
the safety harness’s eye.
SUMMARY OF THE INVENTION
The present invention is directed to a cork remover for a bottle containing sparkling
liquid comprising:
- an outer body, and
- an inner body having cork-gripping means and being slidably mounted in the outer
body,
characterized in that the cork remover comprises a notch for positioning the outer
body over a bottle cork’s safety harness, bottle-gripping means on the outer body for
engaging on the bottle neck and means for restricting the inner body’s sliding
movement in the cork’s expelling direction
BRIEF DESCRIPTION OF THE DRAWINGS
FIG 1 illustrates an embodiment of a cork remover in accordance with the present
invention.
FIG 2 illustrates another embodiment of a cork remover in accordance with the
present invention.
FIG 3 illustrates a preferred embodiment of a cork remover in accordance with the
present invention.
FIG 4 illustrates a cross section of said preferred embodiment.
DESCRIPTION OF THE INVENTION
According to a first embodiment of the present invention and as illustrated in FIG 1, a
cork remover for a bottle containing sparkling liquid is provided comprising:
- an outer body (a), and
- an inner body (b) having cork-gripping means ((c) not shown) and being slidably
mounted in the outer body,
characterized in that the outer body comprises a notch (d) for positioning the outer
body over a bottle cork’s safety harness and releasing the safety harness’s eye.
A first advantage of such cork remover is that the cork, while being lifted and at the
end of the opening process completely released, is held by the cork-gripping means
of the equally lifting inner body.
A second advantage is that, by providing the notch in the outer body, it is not
required to remove the safety harness from the bottle neck bulge before positioning
the cork remover, thereby avoiding accidental cork expel, dangerous situations and
accidents.
In accordance with the present invention, the cork remover may comprise an outer
body having bottle-gripping means, and expel prevention means for preventing the
cork from being entirely expelled.
The advantage of providing the expel prevention means for preventing the cork from
being entirely expelled is that the cork remover is able to resist the high lifting
pressure on the cork in the last phase of the bottle opening process, and that the
user has the ability to controllably release the cork, even in that last phase of the
opening process, such that the genuine quality of the sparkling liquid can be kept.
In an embodiment of the present invention, the expel prevention means may
comprise bottle-gripping means for engaging on the bottle neck and means for
restricting the inner body’s sliding movement in the cork’s expelling direction.
Such restricting means may be any means adapted for blocking the lifting movement
of the inner body relative to the on the bottle neck engaging bottle-gripping means in
the last phase of the opening process, such that the cork is indeed lifted, but not
abruptly expelled and entirely released. Subsequently the user may controllably
release the cork entirely by cautiously removing the cork remover holding the cork.
In a particular embodiment in accordance with the present invention and as
illustrated in FIG 2, the means for restricting the inner body’s sliding movement may
comprise a protrusion (f) on the inner body’s outer side, said protrusion sliding in a
slit (e) that is provided in the outer body and extends at least partially in the cork’s
expelling direction, said slit having a form and size adapted to prevent the cork from
being entirely expelled.
A person skilled in the art will understood that the slit and protrusion may have any
adapted form and size such that the movement of the protrusion and consequently
the inner body is blocked in the cork’s expelling direction in so far that preferably a
minor part of the cork is not expelled.
At least part of said slit may extend straightly in the cork’s expelling direction. In this
case the inner body will move upwardly and turn equally when turning the outer body
(or the bottle) upon opening the bottle.
Alternatively, at least a part of the slit may extend helically in the cork’s expelling
direction. In this case the inner body will move upwardly, but will not turn when
turning the outer body (or the bottle) upon opening the bottle.
In another particular embodiment, the inner body may be extended through the top of
the outer body (see FIG 1 (b)) such that a user is able to resist the high lifting
pressure on the cork and on the inner body by pressing on the top of the inner body
against the lifting pressure (i.e. the user may hold the cork remover in one hand and
pushing with his thumb on the top of the inner body). Subsequently the user may
controllably release the cork entirely by cautiously releasing downward pressure on
the inner body.
In an embodiment, optionally in combination with the foregoing embodiment, the
inner body’s upwardly sliding movement may be blocked by collision with the outer
body such that the cork is prevented from being entirely expelled.
In a preferred embodiment in accordance with the present invention and as illustrated
in FIG 3 and FIG 4, a cork remover may be provided wherein a first part (e’) of the slit
extends straightly in the cork’s expelling direction, said first part’s length being
sufficiently short to prevent the cork from being entirely expelled, and wherein a
second part (e’’) of the slit further extends helically in the cork’s expelling direction for
controllably releasing the cork. Upon turning the outer body, the protrusion will slide
upwardly in the slit and be blocked at the slit’s end. Upon then turning the inner body,
the protrusion will slide in the helical part of the slit such it is moved further upwardly.
An advantage of such embodiment is that the consumer may open a bottle closed by
a cork and safety harness in a safe and uncomplicated way, following the following
sequence:
- placing the outer body (a) sideways on the bottle neck, positioning the notch
(c) over the safety harness’s eye
- sufficiently releasing the safety harness’s eye
- holding the bottle and turning the outer body (a) left or right (or holding the
cork remover and turning the bottle), such that the cork-gripping means and
the pressure in the bottle exert a lifting action on the cork. The inner body (b)
will lift equally and will be blocked by the protrusion (f) at the upper end of the
straight part (e’) of the slit, such that the cork is not expelled entirely.
- turning the inner body (b) such that the protrusion slides in the helical part (e’’)
of the slit. Thereby the inner body is further lifted in a controlled way and the
cork is finally entirely released.
The inner body may have a plurality of protrusions on its outer side, sliding in a
plurality of slits provided in the outer body.
In a particular embodiment the cork-gripping means of the inner body may comprise
a pin (g) or a plurality of pins for intruding into the cork. The advantage of a pin is that
it can easily intrude in the cork without being hindered by the safety harness.
A person skilled in the art will understood that alternative embodiments in
accordance with the present invention are possible wherein the expel prevention
means are likewise based on a slit-protrusion system.
For example, protrusion(s) may be provided at the inner side of the outer body
(instead of at the outer side of the inner body) and a slit may be provided in the inner
body (instead of at the inner side of the outer body), such that upon the inner body
being lifted, the slit slides over the protrusion(s). Such slit in the inner body may be at
least partly straight in the cork expel direction, or at least partly helical in the cork
expel direction, or a combination of both.
In another example, the inner body as a whole may slide in a slit formed by an
adapted inner perimeter of the outer body. The inner body may have a non-cylindrical
outer perimeter fitting and sliding into a corresponding non-cylindrical inner perimeter
of the outer body.
