1. Field of the Invention
This invention relates to devices and methods for removing the skin from a piece of soft fruit, and/or for slicing the meat of the fruit.
2. Description of the Related Art
Traditionally, the meat of certain soft fruit, such as an avocado, papaya or the like, is removed from the skin by cutting the fruit into two halves, separating the two halves from each other, removing the pit or seeds from one or both halves, and either scooping the meat out of the skin with a spoon or peeling the skin away from the meat. Scooping the meat out of the skin is effective, but tends to result in the meat being removed in misshapen or even mutilated pieces. As a result, although the process suffices for making guacamole or chutney, it isn't particularly suited for preparing slices for consumption or for use in sandwiches, hamburger, sushi or other dishes where appearance is important.
Where appearance is important, the skin is typically peeled from the meat, either before or after the meat is sliced. As a result, the slices of fruit can be presented with a consistent and appetizing appearance. Manually cutting, peeling and slicing fruit, however, can be a messy and time-consuming project.
The present invention is directed toward devices for removing the meat from a piece of soft fruit, such as an avocado, papaya or the like, and/or for slicing the meat. In one particular embodiment, the device has a handle portion adapted to allow an individual to manually manipulate the device, and a working portion having an elongated blade and a pair of lateral extensions coupling opposing ends of the elongated blade to the handle portion. The elongated blade has a cross-sectional shape adapted to facilitate movement of the elongated blade through the meat of the fruit. The working portion of the device has a resting configuration in which the elongated blade has a first radius of curvature, and at least one of the lateral extensions is manipulable under a manual force during use to deform the working portion from the resting configuration to a displaced configuration in which the elongated blade has a second radius of curvature, to allow the individual to adjust the curvature of the elongated blade to conform it to the curvature or size of the fruit before and as the elongated blade moves through the meat of the fruit. The working portion of the devices comprises a resilient material such that, when the manual force is removed from the at least one lateral extension, the working portion automatically returns to the resting configuration.
The present invention is also directed toward methods for removing the meat from a piece of fruit, and/or for slicing the meat. In one particular embodiment, the method incorporates providing a device having a handle portion, a working portion and a coupling portion positioned between the handle portion and the working portion; retaining the handle portion with one hand and the piece of fruit with the other hand; and moving the working portion in a cutting direction through the meat of the piece of fruit proximate the skin while simultaneously squeezing the coupling portion laterally with respect to the cutting direction to deform the working portion to conform to the shape of the skin of the piece of fruit as it moves through the meat.
The present invention is also directed toward variants thereof and other embodiments of devices and methods for removing fruit from the skin and/or slicing the fruit equivalent thereto.
The present detailed description is directed toward devices and methods for removing the meat from a piece of soft fruit, such as avocado, papaya or the like, and/or for slicing the meat. The invention could take on other embodiments, and one of ordinary skill in the art, having reviewed the present disclosure and corresponding drawings in their entireties, would readily appreciate modifications that could be made to the illustrated embodiments without deviating from the spirit of the invention. Thus the invention is not to be limited to the specific embodiments illustrated in the drawings and described in connection therewith.
The illustrated core 18 is formed along with the working end 14 and the lateral extensions 16 from a single piece of material; however, an individual of ordinary skill in the art, having reviewed this entire disclosure and the corresponding figures, would appreciate that different constructions, including two, three or more assembled parts, could instead be used without deviating from the spirit of the invention.
The working end 14 incorporates a blade 24 and several teeth 26. The blade 24 extends along a generally arcuate path between the lateral extensions 16. In the illustrated embodiment, the curvature of the blade 24 in the relaxed configuration (i.e., when the device 10 is not being manipulated) is sized and shaped to generally conform to the girth at the waist of a large avocado. The inventors appreciate, however, that the device 10 can be made in different sizes to more closely conform to the different possible sizes of avocados.
The blade 24 is adapted to pass through the meat of an avocado relatively easily. For example, the blade 24 can have a generally wing-shaped cross-section, terminating at the leading and/or trailing edges in an acute wedge and a tapered point. One or both of the edges could be sharpened. Between the edges, one surface of the blade can be generally flat and one of the surfaces can follow a convex curve. Instead, the blade could be wide and flat, with thin but blunt edges. An individual of ordinary skill in the art, having reviewed this entire disclosure and the corresponding figures, will appreciate the variety of shapes and details that can be incorporated into the design of the blade 24 without deviating from the spirit of the invention.
The blade 24 is designed to be sufficiently flexible such that the degree of curvature of the blade can be manually increased or decreased, and to be sufficiently resilient such that the blade will return to its original shape when the bending force is removed. Depending on the material used for the blade 24—be it plastic, nylon, metal, or other suitable materials—the width, thickness and shape of the blade are selected to meet these criteria.
The teeth 26 are spaced apart from each other and extend inwardly from an inner surface of the blade 24 along generally radial paths. Similar to the blade 24, the teeth 26 are sized and shaped to pass easily through the meat of the avocado. In the illustrated embodiment, the teeth 26 are manufactured integrally with the blade 24, such as through injection molding; however, the teeth could instead be separate pieces attached to the blade by known means. The ends of the illustrated teeth 26 opposite the blade 24 are free, allowing the teeth to move freely towards and away from each other as the device 10 is manipulated. The teeth 26 are sufficiently long to cut the entire thickness of a portion of avocado as the device 10 passes through the meat.
In the illustrated embodiment, the device 10 has seven teeth 26, to cut half an avocado into eight roughly equal sections; however, the number and spacing—and even the existence—of the teeth can be changed as desired.
The lateral extensions 16 connect the handle portion 12 and the blade 24, and are positioned to be manipulated by the user, for example, between the user's thumb and forefinger. In the illustrated embodiment, the lateral extensions 16 literally are merely extensions of the blade 24; however, in other embodiments, the ends of the blade could instead be bonded or otherwise coupled to the lateral extensions. The lateral extensions 16 need not be flexible or resilient; they could instead be pivotally coupled or otherwise attached to the handle portion 12, so long as manipulation of the lateral extensions resulted in bending of the blade 24. One of ordinary skill in the art, having reviewed this entire disclosure and the corresponding figures, will appreciate other variations that could be made to the device 10 without deviating from the spirit of the invention.
In the illustrated embodiment, the grip 22 covers the portions of the lateral extensions 16 that will be manipulated by the user. In other embodiments, the lateral extensions 16 can instead by formed, machined, coated or otherwise adapted to provide the user with a secure grip of the device 10 for manipulation. Likewise, the device 10 could be made with no grip.
Embodiments of the present invention can have many advantages over devices and methods of the prior art. For example, the device can quickly skin and/or neatly slice avocado without making a big mess, leaving sliced avocado that can not only be used in guacamole, but could also be presented for use in sandwiches or other meals. These and other advantages may be appreciated by practicing the present invention.
The working end 114 incorporates a blade 124 and several teeth 126. The blade 124 is adapted to pass through the meat of a papaya relatively easily. The teeth 126 are sufficiently long to cut the entire thickness of a portion of papaya as the device 110 passes through the meat. In the illustrated embodiment, the device 10 has three teeth 126, to cut half a papaya into four roughly equal sections; however, the number and spacing—and even the existence—of the teeth can be changed as desired. The illustrated working end 114 is otherwise essentially the same as the working end described above in connection with the previous embodiment.
