| (54) | Cava, champagne, and sparkling wine bottle opener |
| (57) This invention refers to a device that enables the removal of corks from cava, champagne
and sparkling wine bottles, which is handled with only one hand and effortless. The
device is based on using the increment of force supplied by a lever when the fulcrum
and resistance are very close to each other. In our case, the device is inserted in
the slit or groove found in the cava bottles between the head of the cork and the
mouth of the glass bottle. Its practical development is achieved with two blades located
in front of each other, separated between 20 and 25 mm and joint physically. One of
them has an arm that allows the ensemble to move first upwards and, if the cork did
not come out, a downwards movement of the lever will remove the stopper. The mechanical
union of both blades can be made in several ways: 1) joining them through one of their
sides, 2) with two symmetrical steel strips with two opposed blades in an inlet at
the end of each strip, joint together through the closest end, forming a clamp with
its rotation axis on the joining point and 3) through an upper bridge between both
blades.

INVENTION OBJECT
[0001] This invention, according to the title of this descriptive application, refers to a device that enables the removal of corks from cava, champagne and sparkling wine bottles. It has been conceived and carried out to obtain advantages over other existing tools with analogous objective.
PREVIOUS TOOLS
[0002] Various devices, with the shape of pliers or tongues, are known which grab the cork, helping to fasten it, but requiring the same effort in both hands, the one that handles the bottle and the one that turns the cork. This turn, made easier by the pliers, simplifies the exit of the cork but not enough to make opening a bottle of this type an easy task
[0003] Nowadays, there are several kinds of cava and sparkling wines which are very economical and their cork is not covered with paraffin, offering certain difficulty to their extraction. There are a considerable number of people unable to open them.
DESCRIPTION OF THE INVENTION
[0004] The device of the invention uses on the one hand the slit or groove found in the cava bottles between the head of the cork and the mouth of the glass bottle, and on the other hand the increment of force supplied by a lever when the fulcrum and resistance are very close to each other. In our case a small effort generates a considerable thrust on the cork, which exits without difficulty.
[0005] Its practical development is achieved with two blades situated in front of each other, separated about 20-25 mm and physically joint together. One of the blades has an arm that allows the ensemble to move in the following way: both plates, either bevelled or sharpen, slide sideways through the slit between the cork and the bottle mouth. Once in this position, and by means of an upwards applied force, the ensemble works as a second class lever, the fulcrum being the top of the bottle neck, opposite to the point where the force is applied upwards. This causes the resistance to act on the cork, and with very little effort the cork moves in the same direction as the applied force. If the cork did not go out in the first try, the operation can be repeated applying the upwards force at the point where the fulcrum was before and this will finish taking the cork out
[0006] The union between both blades can be achieved in several ways: joining both blades through a lateral bridge, joining them through two lateral sides, or through an upper bridge.
[0007] In order to better explain the description of the device, the current description attaches a set of figures that help to understand the innovations and advantages of the device object of the invention.
[0008] We want to point out to the fact that any one-handed person, with his only hand can open any bottle of cava, champagne or sparkling wine, with no difficulty.
BRIEF DESCRIPTION OF FIGURES
[0009]
Figure 1. This figure represents both blades in the working position, showing a frontal view and a side view.
Figure 2. This figure reveals the device when both blades are joint through a lateral bridge. The upper and side views are shown.
Figures 3, 4, and 5. These figures show in a sequence of drawings the three operations necessary to open the bottle.
Figures, 6, 7, and 8. These figures show a sketch of how the cava bottle opener in figure 2 is used physically and operationally.
Figure 9. This figure makes clear how both blades can be joint together through two lateral sides, forming a clamp with its rotation axis on the joining point.
Figure 10. This figure shows how the union of both blades can be achieved through an upper bridge, which can house the cork once it gets off the bottle. It shows both the frontal and side view.
DESCRIPTION OF HOW TO CONSTRUCT THE DEVICE IN DIFFERENT WAYS
[0010] 1st. According to figure 2 both blades are joint through a lateral bridge. A rectangular inlet of about 20-25 mm wide should be made at the end of a steel strip. Opposed sides of inlet should be bevelled in order to facilitate their entrance through the slit between the cork and the bottle mouth, sliding sideways as shown in figure 3. One of the blades has an arm that allows the ensemble to move up and down. Figure 4 shows how by applying un upward force, the device rest on the top edge of the bottle, and the resistance acts on the corks head making the cork come out slanted, in the same direction as the applied force. If the cork did not go out in the first try, the operation can be repeated applying the upwards force at the point where the fulcrum was before and this will finish taking the cork out. Figure 6, 7 and 8 show a sketch of how the opener in figure 2 is physically used.
[0011] 2nd. In figure 9 two symmetrical steel strips with two opposed blades in an inlet at the end of each strip, are joint together through the closest end, forming a clamp with its rotation axis on the joining point. The blades slide between the cork and the top of the bottle neck, and closing the clamp we are in the previous case. By making and upward and downward movement of the clamp we will take the cork out. If we are interested in keeping the cork nested in the device, a receptacle should be built above the blades so that the cork will remain in that place.
[0012] 3rd. Both blades can be joint through the upper part. If we make a bridge above the blades of a size such that the head of the cork fits inside, we will have both blades joint through the upper part, working in a similar way as the first design and in which the cork will remain in the interior of the device.
1. st. Device to open bottles with cork similar to cava, champagne and sparkling wine,
having two blades opposed to each other, separated about 20 to 24 mm from each other,
joint physically. One of them has an arm that allows the up and down movement of the
ensemble.
2. nd. Device to open cava, champagne and sparkling wine bottles, having two blades opposed
to each other, separated about 20 to 24 mm from each other, joint laterally. One of
them has an arm that allows the up and down movement of the ensemble.
3. rd. Device to open cava, champagne and sparkling wine bottles, having two blades opposed
to each other, separated about 20 to 24 mm from each other, located in a semicircular
inlet on a steel strip, which is joint to a symmetrical strip by the shortest end
of the strips thorough a rotation axis making a clamp.
4. th. Device to open cava, champagne and sparkling wine bottles, having two blades opposed
to each other, separated about 20 to 24 mm from each other, joint through an upper
bridge in which the cork fits in the interior of the device.
