A suction bulb and a tubular structure coupled to the suction bulb enable a user to selectively provide a suction force directed away from the inlet-outlet orifice toward the suction bulb for directing an egg yolk into the tubular structure. The orifice is sized and shaped to receive an egg yolk having a yolk weight, and the selectively provided suction force is greater than the yolk weight for directing the egg yolk into the yolk-receiving structure via the yolk inlet-outlet orifice. The tubular structure may further include a belly compartment that may house the egg yolk for further or later deposition and the bulb may further include a flattened side for preventing rotation of the device and maintaining the belly compartment in a downwardly extended direction. ## Claims ### Claim 1 An egg yolk separator device for separating an intact egg yolk from an egg albumen, the egg yolk separator device comprising: suction means for selectively providing a suction force; and a yolk-receiving structure, the yolk-receiving structure having a tubular construction, a yolk inlet-outlet orifice, and an inner yolk-receiving chamber, the tubular construction having a tubular axis, the yolk-receiving chamber extending radially from the tubular axis for receiving and supporting the egg yolk in radial adjacency to the tubular axis, the yolk-receiving structure being coupled to the suction means such that the selectively provided suction force is directed away from the yolk inlet-outlet orifice toward the suction means, the orifice being sized and shaped to receive an egg yolk having a yolk weight, a vitelline membrane and membrane-contained cytoplasm, the suction force being greater than the yolk weight for directing the egg yolk into the yolk-receiving structure via the yolk inlet-outlet orifice. ### Claim 2 (depends on 1) The egg yolk separator device of claim 1 wherein the suction means are defined by a suction bulb, the suction bulb being constructed from an elastomeric material and defining an inner volumetric space, the suction bulb being compressible to an actuated state for decreasing the inner volumetric space and elastically restorable to a relaxed state for re-defining the inner volumetric space, the elastically restorabililty of the suction bulb for creating the suction force and directing the egg yolk into the yolk-receiving structure via the yolk inlet-outlet orifice. ### Claim 3 (depends on 2) The egg yolk separator device of claim 2 wherein the suction bulb comprises a main body and a circumferential band structure, the band structure having a relatively higher spring constant than the main body for providing the user with means for differing the suction force upon the egg yolk. ### Claim 4 (depends on 2) The egg yolk separator device of claim 2 wherein the suction bulb comprises a flattened outer surface, the flattened outer surface extending in a plane parallel to the tubular axis and orthogonal to the radial direction of the yolk-receiving chamber. ### Claim 5 (depends on 1) The egg yolk separator device of claim 1 wherein the yolk inlet-outlet orifice comprises a rounded outer terminus, the rounded outer terminus for preventing inadvertent rupture of the egg yolk. ### Claim 6 (depends on 1) The egg yolk separator device of claim 1 wherein the yolk-receiving structure comprises a cylindrical inner surface, the cylindrical inner surface for reducing stress on the vitelline membrane and thus for preventing inadvertent rupture of the egg yolk. ### Claim 7 (depends on 6) The egg yolk separator device of claim 6 wherein the yolk-receiving chamber comprises a smooth surface coextensive with the cylindrical inner surface thereby together forming smooth inner yolk displacement surfacing for preventing rupture of the vitelline membrane during egg yolk displacements. ### Claim 8 (depends on 1) The egg yolk separator device of claim 1 wherein the yolk-receiving structure is removably and threadably coupled to the suction means, the removably and threadably coupled yolk-receiving structure being removable for enabling interchangeability of components with the suction means. ### Claim 9 A device for grabbing an egg yolk, said device comprising: suction means for selectively providing a suction force; and a yolk-receiving structure, the yolk-receiving structure comprising an inlet-outlet orifice, a cylindrical axis, and an inner yolk-receiving chamber, the yolk-receiving structure being coupled to said suction means such that the selectively provided suction force is directed away from the inlet-outlet orifice toward the suction means, the inlet-outlet orifice being sized and shaped to receive an egg yolk having a yolk weight, the suction force being greater than the yolk weight for directing the egg yolk into the yolk-receiving structure via the yolk inlet-outlet orifice, the yolk-receiving chamber extending radially from the cylindrical axis for receiving and supporting the egg yolk in radial adjacency to the cylindrical axis. ### Claim 10 (depends on 9) The device of claim 9 wherein the suction means are defined by a suction bulb, the suction bulb comprising a main body and a circumferential band structure, the band structure having a relatively higher spring constant than the main body for providing the user with means for differing the suction force upon the egg yolk. ### Claim 11 (depends on 9) The device of claim 9 wherein the inlet-outlet orifice comprises a rounded outer terminus, the rounded outer terminus for preventing inadvertent rupture of the egg yolk during a grabbing event. ### Claim 12 (depends on 9) The device of claim 9 wherein the yolk-receiving structure comprises a cylindrical inner surface, the cylindrical inner surface being radially equidistant from the cylindrical axis, the cylindrical inner surface for reducing stress on the vitelline membrane and thus for preventing inadvertent rupture of the egg yolk. ### Claim 13 (canceled) ### Claim 14 (depends on 12) The device of claim 12 wherein the suction means comprises a flattened outer surface, the flattened outer surface extending in a plane parallel to orthogonal to the cylindrical axis for preventing the device from rolling upon a support surface. ### Claim 15 (depends on 13) The device of claim 13 wherein the yolk-receiving chamber comprises a smooth surface coextensive with the cylindrical inner surface thereby together forming smooth inner yolk displacement surfacing for preventing rupture of the vitelline membrane during egg yolk displacements. ### Claim 16 (depends on 9) The device of claim 9 wherein the yolk-receiving structure is removably and threadably coupled to the suction means, the removably and threadably coupled yolk-receiving structure being removable for enabling interchangeability of components with the suction means. ### Claim 17 A method for moving an intact egg yolk, the method comprising the steps of: sucking an intact egg yolk into an egg-receiving structure via a suction force in a first direction away from a first location; displacing the egg-receiving structure with the intact egg yolk contained therein to a second location; and directing the intact egg yolk in a second direction within the egg-receiving structure after sucking the intact egg yolk into the egg-receiving structure in the first direction. ### Claim 18 (canceled) ### Claim 19 (depends on 17) The method of claim 17 wherein the step of directing the intact egg yolk in the second direction within the egg-receiving structure comprises the step of chamber-receiving the intact egg yolk in the second direction radial to the first direction. ### Claim 20 (depends on 19) The method of claim 19 wherein the step of directing the intact egg yolk in the second direction comprises the step of gravitationally forcing the intact egg yolk in the second direction radial to the first direction.
