The invention relates to a device for cutting fruit and vegetables, in particular onions, having a cutter member that has a plurality of blades and having a counterpart element against which the cutter member is pressed for cutting the material to be cut, wherein the counterpart element has a punch which presses the material to be cut through the cutter member, or the blades thereof.
An onion chopper of this kind is known for instance from International Patent Disclosure WO 02064331 A1, with a boardlike cutter element and a counterpart element, likewise embodied on the order of a board, that receives the onion to be cut. For cutting an onion, the cutter element is pivoted upward from the counterpart element that rests on an underlying support, and the onion to be cut is placed on a punch located on the counterpart element. After that, the cutter element is pivoted back onto the counterpart element, exerting a pressure, until the blades plunge into corresponding indentations on the punch. In the process, the onion is cut apart by the cutting grid of the cutter element and by means of the punch is pressed all the way through the cutting grid. Once the cutter element rests on the counterpart element, the material that has been cut is located on the top side of the cutter element and can be removed from the cutter element, for instance with the aid of a knife.
A disadvantage of this device is that pieces of the cut onion can drop unintentionally from the top side of the cutter element, for instance onto the floor. This often occurs when onions are being cut, since because of their oval shape the onion tends to fall apart after being cut.
A further disadvantage in this device is that the essential oils of the onion can develop freely after the cutting, causing the well-known irritation to the eyes of the user. It is also necessary to remove the cut onion from the top side of the cutter element when further onions are to be cut.
Furthermore, cleaning the punch proves difficult, since the essential oils of the onion can collect in the indentations in the punch, and the counterpart element can be cleaned only together with the punch.
It is therefore the object of the invention to further develop a device for cutting fruit and vegetables, in particular onions, having the characteristics recited at the outset, in such a way that while overcoming these disadvantages, handling of the device is improved substantially.
This object is attained by a device having the characteristics recited at the outset, in which for receiving the cut material, a container is releasably disposed on the cutter member, on its side remote from the counterpart element, in the region of the blades.
By means of the invention, it is attained that the cut onions, for instance, after being cut are received in the container and are secured against falling out. Also, the essential oils of a cut onion, for instance, cannot develop their eye-irritating effect, since they are essentially locked away from the environment by the container. Moreover, the container according to the invention offers the advantage that a plurality of kinds of material to be cut can be cut in succession, without requiring that the already-cut material be removed from the device and placed in a separate container. Once the desired quantity of vegetables, onions and the like has been cut, the device of the invention is simply turned over, so that the receiving container is now underneath the cutter element. The container is then released from the device, whereupon the cut material is held in the container and can be kept ready for further processing. In order here as well to suppress the irritating effect of the essential oils of a cut onion, a separate cap for closing the container once it has been released from the device may be provided. The cut material can then be stored in the container in airtight fashion until it is further processed.
In a first advantageous embodiment of the invention, the container is retained releasably on the cutter element by means of a bayonet mount. Alternatively, however, it is possible to use a screw closure or a detent connection. All these means assure fast, simple release of the container from the cutter element and its fastening to it.
To enable monitoring the fill level inside the container, in an embodiment of the invention the container comprises transparent material.
In a further concept of the invention, the punch is releasably held on the counterpart element, so that after use the punch can be released from the counterpart element and subjected separately to intensive cleaning. This is especially applicable whenever the cut material releases eye-irritating essential oils that can stick to the punch.
In this respect as well, for simple, fast release of the punch from the counterpart element and securing it to the counterpart element, it is provided that the punch is releasably disposed on the counterpart element by means of a bayonet mount. Screw closures but in particular detent connections are preferably employed.
To prevent the punch, in the cutting of the material to be cut and in particular when detent connections are used between the punch and the material, from being released unintentionally from the counterpart element by the pressure exerted on the material to be cut, the punch can be disposed in captive fashion on the counterpart element by means of fastening elements.
It has proved advantageous that the fastening elements have at least one clamping means that can be secured to the counterpart element and the punch by means of screws or similar fastening means.
In another especially advantageous embodiment of the invention, the blades form a cutting grid. As a result, the material to be cut is cut into small block-shaped pieces, which in the case of onions, for instance, because of their shell-like structure, fall apart into more or less small pieces or cubes of onion. In this respect only one cutting operation is required to obtain cut material that is cut as small as possible. In that case, the punch on the counterpart element should have a likewise gridlike structure of its indentations that the cutting grid engages.
In a further advantageous embodiment of the invention, the cutter element and the counterpart element are supported pivotably on one another. Since the cutter element acts as a lever, the expenditure of force in cutting is reduced considerably.
To assure simple, thorough cleaning of the individual parts of the device of the invention, it is provided that the cutter element and the counterpart element are likewise releasably joined together.
In still a further concept of the invention, both the counterpart element and the cutter element are embodied in boardlike fashion, which simplifies handling of the device substantially.
It is furthermore provided that blades are retained in a frame disposed releasably on the cutter element. As a result, the blades can easily be released from the cutter element and subject to thorough cleaning. The blades can also be replaced easily, if they should have become dull after long use.
Further characteristics, advantages, embodiments and possible applications of the present invention will become apparent from the ensuing description of one exemplary embodiment in conjunction with the drawings. All the characteristics described and/or shown in the drawing are the subject of the present invention on their own or in arbitrary appropriate combination, including independently of how they are summarized in the claims or the claims dependencies.
Shown are:
The device shown in the drawings substantially comprises a cutter element 3 and a counterpart element 4, as the drawings show. As
A plurality of blades 2 combined into a grid are integrated into the cutter element 3.
On the side of the cutter element 3 remote from the counterpart element 4, in the region of the cutting grid, a container 6 is retained releasably by means of a bayonet mount 7.
The counterpart element 4 has a base 9, for placing the device on a work surface (not shown). The base 9 is disposed on the side of the counterpart element 4 remote from the cutter element 3. On the side of the counterpart element 4 toward the cutter element 3, there is a punch 5, on which the onion or similar material to be cut is placed.
The punch 5 has indentations 8, which correspond with the blades 2 of the cutter element 3 and into which the blades 2 dip when the cutter element 3 is resting on the counterpart element 4. To press the onion all the way through the blades 2, the indentations 8 are embodied as deeper than the height of the blades 2.
As can be seen particularly in
The blades 2 in
In the exemplary embodiment of
Before the cutting operation, the counterpart element 3 is pivoted upward relative to the counterpart element 4, and the material to be cut is placed on the punch 5. In this position, the container 6 is located on the top side of the cutter element 3. The cutter element 3 is now pressed downward onto the counterpart element 4, whereupon the blades 2 cut the material to be cut into pieces of rectangular cross section. Once the cutter element 3 is resting on the counterpart element 4, the material being cut has been pressed by the punch 5 all the way into the container 6, through the blades 2 in the cutting grid.
The blades 2 of the cutting grid are arranged such that in the event that the cutter element 3 is pivoted again for cutting further onions, the cut material is prevented from falling out of the container 6 through the cutting grid. The quantity of cut material can be checked, because of the transparent container 6.
As soon as there is a desired quantity of cut material in the container 6, the device is turned over into the position shown in
For cleaning the device, its individual parts, such as the cutter element 3, counterpart element 4, punch 5, container 6, blades 2, and frame 13, can be separated from one another.
