This invention relates generally to food preparation devices, including devices for chopping or slicing onions, mushrooms, and the like.
In preparing food, it is often desirable to prepare onions by slicing them in strips or chopping them into small pieces. Most commonly, this is done by using a knife There are other specialty-designed devices for chopping foods, including some devices having a lid having a grid of projections which pivots downward to push the onion or other food item through a grid of blades. The current devices lack certain features that can sometimes make them less desirable to use, or which can improve their functionality.
A food chopper includes a lid pivotally moveable with respect to a blade tray, in which the lid includes a set of projections configured to extend through openings in a grid of blades carried on the blade tray. A reservoir is positioned beneath the grid of blades to catch chopped food items, and in the preferred version of the invention the reservoir is removably attached to the blade tray.
In accordance with a preferred example of the invention, the reservoir is slideably attached to the blade tray, most preferably it can slide outward and away from the blade tray along a path that is parallel to a plane defined by the blade tray.
In some examples of the invention, the blade tray includes a frame which reinforces the perimeter of the blade tray.
In some versions of the invention, the blade tray is supported by a stand which may be formed as legs which are mounted to the reinforcing frame. The legs may terminate in feet configured to rest on a countertop.
In one preferred example, the blade tray includes a ledge for supporting the reservoir, and the ledge may be formed from one or more wires extending from the blade tray, the wires engaging a peripheral shoulder or flange formed on the reservoir.
The reservoir may include one or more handles to facilitate removal of the reservoir from the blade tray.
In some versions, the blade tray may include multiple grids of blades and the lid may include corresponding multiple grids of projections. The chopper may optionally include a pick and storage for the pick on the blade tray,
Preferred and alternative examples of the present invention are described in detail below with reference to the following drawings:
A preferred food chopper, suitable for cutting or slicing onions or other food. items, is illustrated in the accompanying figures. In the embodiment as illustrated, the food chopper includes a lid 20, a blade tray 50, and a food reservoir 40. The blade tray and the lid are pivotally connected to one another, with the blade tray supporting an upper rim 41, 42 of the reservoir which is suspended below the blade tray.
The lid 20 is generally rectangular in shape, having squared corners at a first end that is pivotally connected to the blade tray, with rounded corners at a second end opposite the first end. A downward-extending flange 29 surrounds the peripheral edge of the lid (see
The lid further includes a grid of projections on the inner surface, extending downward in the same direction as the flange. In a preferred version of the invention the lid 20 includes two separate grids of projections 71, 72, each spaced apart from one another. The projections may take on any size or shape, as desired, and are ideally shaped to thoroughly push the food through the blades within the blade tray.
As discussed further below, the blade tray 50 includes a network of blades configured at right angles and forming generally square openings. in the preferred version as illustrated in
In some versions, as described above, the blade grids are removably attached. to the frame to allow for selection and replacement of blades having desired spacing. For example, two different grids of blades 81, 82 may be selectively used in a first one of the openings 52 formed in the tray 50. One of the two grids of blades 81 includes a larger number of blades spaced more closely together within a frame while the other of the two grids of blades 82 includes fewer blades spaced farther apart.
As best seen in
The projections 71, 72 on the lid are sized and located within the lid such that when the lid is closed one or more projections fits within each of the blade openings. Where two separate groupings of blades and projections are formed, each separate set of projections 71, 72 is configured to extend through a separate grid of blades e.g., 82, 83. Though shown as intersecting blades, in some versions the network of blades may have only parallel blades thereby forming elongated openings, or blades forming wedge shapes.
In one example of the invention, as best seen in
As seen for example in
The upper rim of the reservoir includes a pair of diametrically opposed flanges 41, 42 used to support the reservoir beneath the frame. In the version as illustrated, the two flanges extend laterally outward from the upper rim of the reservoir short distance. The two flanges interact with complementary support surfaces provided on the blade tray. The upper rim of the reservoir preferably further includes an opposing pair of handles 43, 44 which in the illustrated version are formed as elongated flanges that extend downward and laterally away from portions of the rim. Most preferably, the support flanges 41, 42 are positioned on a first pair of opposing sides of the reservoir while the handles 43, 44 are positioned on the sides of the reservoir between the support flanges. In the illustrated example, the reservoir is rectangular and the handles extend substantially along the entire length of the long side of the reservoir. In other versions the reservoir may be shaped differently and the handles need not extend along the entire side.
The tray 50 preferably includes an interior support structure 60, as best seen in
As seen in
The inner support. structure 60 is attached to the tray 50 using a series of rivets, bolts, or other fasteners 95 spaced about the perimeter of the frame.
In other versions, the tray may be formed as a single unitary component rather than including a separate inner support structure and outer tray structure. Likewise, in other versions the legs may be integrally formed with the inner or outer supports structure, may be attached to the outer tray member, or may be attached in another fashion. In yet other versions, the legs may be excluded and instead the upper frame member is supported by the lower reservoir.
A pair of tray supports 63, 64 is attached to a lower surface of the blade tray in order to support the lower reservoir and suspend it from the blade tray. In general the tray supports are substantially horizontally-extending surfaces that support, the reservoir, and they may extend from the tray, the inner support structure, or the legs. In the preferred example, the tray supports are configured as bent wires attached to and extending downward from the tray, and curving along a path that includes a horizontal expanse between opposing sides of the blade tray. In this manner, the wire tray supports form surfaces that are spaced apart from one another in order to enable the flanges 41, 42 on the reservoir 40 to rest on top of the supports. The supports are also preferably positioned at a height beneath the blade tray such that the rim of the reservoir is frictionally retained in between the supports and the tray to a degree that the reservoir will not readily slip out of place under its own weight, but a user may readily slide the reservoir out of position if desired.
The blade tray includes a boss 57, 58 provided at each of the two opposing sides of the rearward end of the blade tray. The bosses are configured to be received within a pair of bores 27, 28 at opposite sides of the rearward ends of the lid, forming the pivotal connection between the lid and the blade tray. A pair of endcaps 21, 22 enclose the bores. Accordingly, the lid is able to rotate about the pivotal connection from an open position that is preferably at least about 90 degrees with respect to the blade tray to a closed position resting adjacent and substantially flush with the blade tray.
In some embodiments of the invention, the reservoir also includes volumetric measurements on an inner or outer surface.
The exterior surface of the blade tray 50 is preferably formed in the same shape as the lid 20, such that in the preferred embodiment it comprises a rectangular shape with rounded corners. The outer surface of the tray is preferably slightly smaller than the interior width of the vertical sidewalls of the lid so that the blade tray is received within a portion of the lid when the lid is rotated downward against the tray.
The blade tray 50 includes a flat upper surface that transitions to a generally vertical peripheral wall, The grids of blades are preferably positioned such that the sharpened top edge of the blades is within, or substantially close to, the plane defining the upper surface, The watt peripheral wall of the blade tray is sized and configured such that the wall is substantially vertically above the outer side walls of the reservoir, so that food items dropping through the grid of blades are received and retained within the reservoir.
Each of the lid, tray, and reservoir is preferably formed from plastic, except for the blades, support structure, and legs as noted above. In a preferred form, at least the reservoir is formed from clear plastic to enable the user to see the volume of food inside.
In use, the user places an onion (or other food item) atop either of the grids of blades while the lid is pivoted upward to an open position. By pressing against the lid, causing pivotal and downward rotation of the lid, the grid of projections is pressed against the onion, In turn, the onion is pressed against the grid of blades, urging it through the blade openings and producing chopped onion sections having a cross-sectional shape that is the same as the blade openings. Once the lid approaches the blade grid, the projections press through the grid to clear any remaining food from the grid.
When the reservoir is full, or the chopping is completed, the reservoir can be slid outward horizontally. For example, as shown in
The legs 30, 31 forming the stand that support the blade tray each terminate in a foot 102, 104. Most preferably, the reservoir is suspended by the blade tray such that when the blade tray is attached to the reservoir, the reservoir is positioned above a countertop or similar horizontal surface 100, such as seen in
If desired, the reservoir may be slid away from and folly removed from the tray, for example as shown in the disassembled view of
A cleaning grid 73, 74 is provided in some versions of the invention. The cleaning grid is formed in a generally planar shape having a first grid 73 and a second grid 74, each of the first and second grids comprising a series of holes for receiving a separate one of the projections in the first and second sets of projections. The cleaning grid has an outer perimeter sized to fit within the sidewalk of the lid. The holes in the cleaning grid are sized to snugly receive the projections, such that when the grid is pressed into place or removed it closely scrapes along the projections.
In use, the cleaning grid is pressed against the projections such that the projections extend through the grid. Most preferably the cleaning grid is pushed upward to rest up against or close to the inner surface of the lid. As such, the lid is configured so that the projections can extend through the blade spaces with the cleaning grid in place, against the inside surface of the lid, The snug fit between the projections and the cleaning grid holes are sized so that a strong prying force is required to remove the cleaning grid. After using the food chopper to chop onions, apples, or other food items, the cleaning grid can be removed from the inside of the lid, The removal of the cleaning grid causes it to scrape along the projections, removing bits of food as the cleaning grid is removed.
While the preferred embodiment of the invention has been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is not limited by the disclosure of the preferred embodiment. Instead, the invention should be determined entirely by reference to the claims that follow.
