Description:
Food Crusher

FIELD OF INVENTION

[0001] This invention relates to a kitchenware, and in particular kitchenware for pressing and crushing food.

BACKGROUND OF INVENTION

[0002] Crushed food, e.g. garlic and ginger, is frequently required in recipes. For example, over the years there have been a number of different designs of hand- held garlic press designed for people to crush garlic by hand. Generally, the garlic to be crushed is placed into a cup or receiver that contains holes in a perforated sieve. A ram or piston is forced into the cup, pressing the garlic through the holes. However, in such designs the garlic residue in the perforated holes is very difficult to clean, even with other accessorial tools such as a comb. Also, the perforated sieve is located at the bottom of the cup where inaccessible regions created by the perforated sieve joining the interior of the cup at right angle are created which also makes cleaning difficult.

[0003] United State patent No. 5,101,720 disclosed a double hinged garlic press as shown in Fig. 1. This double hinged garlic press contains a hinged wall 10 coupled to the receiver 12 and the plunger 14 by two hinges. Since the hinged wall 10 can be opened and closed with respect to the receiver 12 or plunger 14, the hinged wall 10 which contains the perforated holes can be exposed for cleaning. However, the difficulty of cleaning the garlic press still remains as the perforated holes on the hinged wall are still filled with the garlic residue which is hard to remove.

SUMMARY OF INVENTION

[0004] In the light of the foregoing background, it is an object of the present invention to provide an alternate food crusher to allow simple and convenient cleaning. [0005] Accordingly, the present invention, in one aspect, is a food crusher which contains a crushing member coupled to a base member and movable between an open and a close position. The crushing member has a crushing area and the base member has a receiving surface facing the crushing area for crushing food therebetween. The crushing area and the receiving surface each contain an undulating topography complementary to each other whereby food placed on the receiving surface will be crushed therebetween when the crushing member is moved to the closed position, and crushed food is squeezed out of the closed crusher from the edge of the crushing area and the receiving surface.

[0006] In a preferred embodiment, the base member of the food crusher further contains a pattern on the edge of the receiving surface, such that when the crushing member is moved to the closed position, the crushing area and the pattern creates a plurality of holes along at least one edge out of which the crushed food can be squeezed.

[0007] According to another aspect of the present invention, there is provided a food crusher that contains a crushing member coupled to a base member and movable between an open and a close position. The crushing member has a crushing area and the base member has a receiving surface facing the crushing area for crushing food therebetween, wherein the crushing area and the receiving surface are both integral surfaces without holes traversing therethrough whereby food placed on the receiving surface will be crushed therebetween when the crushing member is moved to the closed position, and crushed food is squeezed out of the closed crusher from the edge of the crushing area and the receiving surface.

[0008] One of the most significant advantages of the present invention is that while it is used like a normal food crusher to crush the food, the holes through which the food is crushed are created only when the holding member is in the hold position. There are no permanent perforations or holes on the base of the food crusher. Since there is no hole in the base, the garlic residue that hasn't been pressed out can be easily cleaned of by just rinsing the crushing area or the receiving surface with water.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] As used herein and in the claims, "couple" or "connect" refers to mechanical coupling or connection either directly or indirectly via one or more mechanical means unless otherwise stated.

75 [0018] Referring now to Fig. 2a , 2b, 4a and 4b, the first embodiment of the present invention is a food crusher 20 which is suitable for crushing food such as garlic. The food crusher 20 includes a base member 21 or simply base 21, and a crushing member 30, coupled with each other by a first hinge 26. The crushing member 30 acts like a piston. The base 21 further connects to a first handle 24 and similarly, the crushing member 30

80 connects to a second handle 22. In this specific embodiment, both the crushing member 30 and the base member 21 are integral surfaces without holes traversing there through. A holding member, or called container 28, is also coupled to the base 21 by a second hinge 36. The container 28 has two side walls which are substantially in a fanshape according to the embodiment shown. Due to the first hinge 26, the food crusher 20 is movable

85 (rotatable) between an open position and a close position, and due to the second hinge 36, the container 28 is movable (rotatable) between a hold position (the position of container 28 as shown Fig. 2a) and a release position (the position of container 28 as shown Fig. 4b).

[0019] The interior side of the base 21 is also called the receiving surface 32 on which the food to be crushed will be placed. There is a counterpart which is called the crushing area

90 34 on the crushing member 30 that faces the receiving surface 32. On each of the crushing area 34 and the receiving surface 32, is a pattern in the form of an undulating topography. In the embodiment shown in figure 2a , 2b, 4a and 4b, the undulating topography is a series of ridges interpolated by valleys (as shown by arrow 35 in Fig. 2b). In this exemplary embodiment, the length of the ridges is running parallel to the axis of rotation

95 of the first hinge 26. In other embodiment, the length of the ridges could also be running concentric or in other ways, as long as it creates a downward pattern. The crushing area 34 and the receiving surface 32 have similar ridges and valleys with similar widths, but are staggered in their position relative to the hinge 26 such that they are complementary to each other, with the ridges of the crushing area 34 pressing down on to the corresponding 100 valley of the receiving surface 32 when the food crusher 20 is in the close position.

[0020] Now turning to the operation of the device described above, Figure 2a and 2b, together with Fig. 3, shows how the device according to the food crusher 20 in the present invention may be switched from an open position to a close position. Here the operation of the food crusher 20 will be described using the garlic-crushing as an example. During

105 operation, the user first move the container 28 to the hold position pivotably around the second hinge 36 as shown in Fig 2a and 2b. As the undulating topography on the receiving surface 32 forms a plurality of grooves across the whole receiving surface 32 traversely from edge to edge, the edge of the container 28 in the hold position does not fully engage and close off the edge of the base member 21 but creates a plurality of holes which are the

110 cross-sectional recesses of the grooves of the undulating topography on the receiving surface 32.

[0021] The user then puts the garlic to the container 28 of the food crusher 20 in the open position, and grips the first handle 24 and the second handle 22 to make the two handles moving to the close position, as shown in Fig. 3. As the crushing member 30 and the base

115 member 21 are pressed together by the user griping the two handles, the garlic on the receiving surface will be squeezed between the crushing area 34 and receiving surface 32. At the same time, the container 28 in the hold position forms a securing wall along the edge of the crushing area 34 and the receiving surface 32 to prevent the garlic from slipping out of the food crusher 20. As a result, the plurality of holes created at the edge

120 of the receiving surface 32 and the container 28 are the only exit for the crushed garlic material. The garlic will therefore be forced through the plurality of holes at the edge.

[0022] Now the cleaning process of the food crusher 20 will be described. In one embodiment of the present invention as shown in Fig. 4a and Fig. 4b, after the garlic is crushed, the user now opens the food crusher 20 by pulling the first handle 24 apart from 125 the second handle 22 pivotably around the first hinge 26. The container 28 may also be freely movable between the hold position and the release position by rotation along a second hinge 36 as shown in Fig. 4a and 4b. As one can see, the receiving surface 32 and the base member 21 are now completely exposed with no perforations, and in fact a sufficient space is created between the various parts of the food crusher 20 to facilitate 130 cleaning. If there is any garlic residue remaining on the receiving surface 32 that hasn't been pressed out, it can be easily cleaned off by just rinsing with water. The same applies to any garlic residue left in the holder and the crushing area 34.

[0023] The exemplary embodiments of the present invention are thus fully described. Although the description referred to particular embodiments, it will be clear to one skilled 135 in the art that the present invention may be practiced with variation of these specific details.

Hence this invention should not be construed as limited to the embodiments set forth herein.

[0024] For example, in the embodiment shown above, the crushing member 30 and the base member 21 are coupled to each other by the first hinge 26, and the container 28 is 140 coupled to the base member 21 by the second hinge 36. One skilled in the art should realize that as long as the container 28 is movable from the hold position to the release position with respect to the base member 21 as described above, the means with which coupling is achieved can be varied without departing from the spirit of the invention.

[0025] In the embodiments described above, the shape of the sidewalk of the container 28 145 is substantially a fanshape. But it is clear that other shapes of the sidewalk of the container

28 may be used according to the user's preference, such as oval, square, rectangular in shape, as long as the container is able to secure the food material from slipping out of the crushing area during crushing.

[0026] As shown in Fig. 5a and 5b, there can be various configurations of the undulating 150 topography on the receiving surface 32 and the crushing area. In Fig. 5a, the cross- sectional shape of the container 28 and the shape of the receiving surface 32 is rectangle. In Fig. 5b, the cross-sectional shape of the container 28 and the shape of the receiving surface 32 is a truncated eclipse, and the width of each groove of the undulating topography varies from one end of the receiving surface 32 to another end. One with ordinary skills in the art should realize that there can be many other designs for the shapes of the receiving surfaces and the undulating topography, as long as they can facilitate effective crushing and expelling of the food.
