Definitions

  • This invention relates to the accessing of edible flesh covered with hard shells or shell-like structures, such as crustaceans, and a tool for use in this activity.
  • US patent no. 5,403,230 shows a shucking tool that could conceivably be used for striking a shell for cracking it open, and relies on a serrated, pointed end being inserted into a shell for cutting from the inside using a levering action.
  • US patent no. 5,586,931 discloses a crab leg opener having a bulbous part for striking and cracking or crushing a shell, with upper and lower jaws between which a shelled portion of the crab such as a claw is received, and a single ripping tooth.
  • a disadvantage of the above tools is that the single tooth is found to be ineffectual in retaining the shell while being ripped. Another disadvantage is that the shell needs to be cracked or crushed to obtain access to the contents.
  • a flesh accessing tool for accessing flesh at least partially encased in a hard cover comprising an elongate body having, at a first end, a formation for gripping and, at a second end, a cover rupturing means and a ripping means comprising fixed opposed first and second fixed jaw members defining between them a gap within which a portion of covered flesh is receivable for ripping the covering.
  • the flesh may be any edible flesh, including any meat from an animal, fruit or vegetable, that is encased or at least partially encased in a hard cover, such as a shell or shell-like structure, that must be cracked, ruptured or ripped to access the flesh.
  • a hard cover such as a shell or shell-like structure, that must be cracked, ruptured or ripped to access the flesh.
  • Non-limiting examples include jackfruit, durian, gourds, snake-skin fruit, cannonball fruit, molluscs such as snails, oysters, scallops and mussels, as well as crustaceans, such as, crabs, lobsters, crayfish, shrimp and prawns.

  • the tool of the invention may be used for opening the protective coverings of edible flesh in a number of animals and creatures, and well as fruits and vegetables. It should not be regarded as being limited to use in preparing seafoods.
  • first and second or lower and upper, respectively, are used when referring to the jaw members of the tool of the invention. These terms are not to be considered as limiting the tool to use in a particular orientation, but are for convenience, especially when interpreting the drawings. It will be evident that the tool is able to be used in almost any orientation in which a portion containing inaccessible flesh is presented for opening.
  • a flesh accessing tool is generally denoted by the number 10 and shown in side view.
  • the flesh accessing tool is shown to comprise an elongate body 12 shaped to define a handle 14 at a first end and a pair of jaws 16 at an opposite, distal end.
  • the jaws are fixed and not capable of relative movement.
  • An upper jaw 18 (or“second jaw member”) ends in a bulbous club head 20.
  • the club head contributes from 50% to 90% of the weight of the tool as a whole. It would be understood that by concentrating the weight of the tool in the bulbous club head, this will assist in the bulbous club head effectively rupturing the flesh covering in a localised fashion, and minimising the force required by the user the rupture the cover.
  • the weight of the club head alone is in the range 30 g to 300g and further preferably in the range 30g to 150g.
  • the tool may be made of any suitable material, such as metal, plastic, glass and/or nylon and/or combinations thereof.
  • the tool may be made with a metal or steel inner, with a composite material outer, such as a glass/nylon composite material.
  • each tooth defines a convex, arcuate cutting edge 26.
  • the shape can be thought to resemble a mini-version of a plough shear.
  • the edges are located substantially concentrically to splay out in a forward direction from a mid-zone of the head to be inclined toward the open end of gap 22, which separates the respective jaws. The splay angle forward assists in engaging the outer surface of the covering concealing the flesh below.
  • a recessed convex surface 38 for seating against a larger part of the covered flesh, providing the opportunity of adding to the stability of the tool.
  • surface 38 may abut the covered flesh as well as provide clearance for the foremost upper arcuate blade 26a to cleave the flesh covering.
  • the lower jaw (or“first jaw member”) is in the shape of a concave arc defining a curved blade the cutting edge of which is directed towards or into the gap, to face the upper jaw and its protruding bladed teeth.
  • the convex upper tooth edges of the upper jaw are generally inclined orthogonally to the plane occupied by the concave arcuate edge of the lower jaw blade.
  • the user places the covered portion of felsh between the jaws and engages the portion with teeth members 24 of club head 20 of the upper jaw. Then, by pivoting the hand grip end of the tool upward using the centre of the head as pivot point, the user brings blade 36 of the lower jaw into slicing contact with the portion in a severing action.
  • This may also suitable for flesh not enclosed in a shell, such as that of a crustacean shellfish, but also flesh enclosed in a hard cover, such as some fruits and vegetables.
  • the club head of the upper jaw promotes a cutting action by the lower jaw, without losing upper jaw grip even when rocked side to side, despite the lack of relative movement between the two jaws. Grip retention is enhanced by the teeth having cutting edges arranged in a curved array, subtended by the ball-like shape of the bulbous club head.
  • FIG. 2 An alternative embodiment of the tool is illustrated in Figure 2, where like numbering is used for like parts.
  • the blade of the lower jaw 32 is replaced by a line of tooth members 44 that are generally pyramid-shaped and protrude into the gap between the jaws.
  • the tooth members may be arranged in more than a single line, with their edges not being coplanar, as is evident in the front view of Figure 3.
  • cutting edges 26 of the upper jaw are particularly suitable for gripping, for example, the shell of a crustacean, leaving lower teeth 44 to perform a ripping function instead of slicing.
  • the ripping action creates a line of rupture through the shell, generally separating it into detachable sections on either side of the plane in which lower jaw 32 lies.
  • club head 20 is of generally spherical shape above the lower portion from which teeth 24 splay. However, in still further embodiments, it may take on other shapes, including ovals and regular faceted shapes, for example cubic, tetrahedral and the like.
  • the extending teeth are integrally formed with the head. However, it is contemplated that the teeth may be separately formed with base protrusions that allow for interlocking connection with complementally threaded sockets provided in the head.
  • the base of the teeth may in other embodiments include insertable formations of other shapes and fastening mechanisms for securing them in place.
  • a spike 28 Extending optionally from club head 20 at a location that is generally opposite that of teeth 24 is a spike 28. It may be made of a metal alloy, for example a salt-resistant grade of stainless steel and is screw threaded at its proximate end that is received into a complementally threaded socket in the surface of the head. In other embodiments of the invention, the spike may be made of a hardened plastic, nylon-reinforced composites, or a glass fibre reinforced plastic or nylon, or may be a metal spike covered in a thin layer of these materials. The spike is further adapted for rupturing by penetrating the hard, outer shell of a shellfish, such as a crab and its pincer, by having a pointed distal end 30. The diameter of the pin shaft is 4mm before it tapers to a point, but may be of another diameter in an alternative embodiment.
  • the bulbous club head is preferably made from a metal of density the like of cast iron or stainless steel.
  • the invention makes use of both the mass of the ball portion for supporting the pin in its driving force in penetrating the shell and provides a shape from which the divergent teeth diverge, thereby allowing for a more secure cut at multiple angles.
  • the piecing spike may be optionally added to the tool of Figure 1 to provide it with a further functional dimension.
  • the plurality of teeth on both jaws advantageously improves the ease of engagement for ripping.
  • the fan-shaped nature of the teeth extending from bulbous head 20, resembling a partially sliced-open fruit, provides further opportunities for engagement, ripping and slicing, as well as for stabilising the shell portion undergoing ripping motion and for retaining it in position for ripping in relation to the jaws.
