Abstract
A food cutting device has a body frame defining an aperture, and a cutter removably located within the aperture. The body frame has a first engaging formation and the cutter has a second engaging formation adjacent and releasably engageable with the first engaging formation for connecting the cutter to the body frame to produce a unitary structure for a cutting operation.
Claims8
A food cutting device comprising:
- a frame including a wall defining, within the wall, a circular aperture having a central axis aligned with a cutting direction of the food cutting device,
- first and second L-shaped slots in the wall, each of the first and second L-shaped slots including a first portion that is parallel to the axis and extends to an edge of the wall, and a second portion that is transverse to the axis, and
- first and second linear recesses in the wall, parallel to the axis;
- and a cutter including
- a circular cutter ring having a wall with an outside surface, the cutter ring being removably locatable within the aperture of the frame,
- a plurality of cutting blades surrounded by and fixed to the cutter ring,
- first and second protrusions on the outside surface of the wall of the cutter ring and receivable in the second portions of the first and second L-shaped slots, respectively, to engage the frame to the cutter ring and prevent separation of the cutter ring from the frame in response to forces applied to the along the axis to the frame and the cutter ring,
- a peripheral flange transverse to the axis and extending outwardly from a lower edge of the cutter ring, and
- first and second buttons mounted on the peripheral flange and outwardly spaced from the outside surface of the wall of the cutter ring, for handling of the cutter, each of the first and second buttons including a projecting bump facing the outside surface of the wall of the cutter ring, wherein
- the peripheral flange covers any gap between the wall of the frame and the wall of the cutter ring when the cutter ring is engaged with the frame, and
- the first and second buttons releasably engage the first and second linear recesses in the frame when the first and second protrusions are engaged in the second portions of the first and second L-shaped slots, respectively, to resist rotation of the cutter ring, relative to the frame about the axis.
