Title: Egg packaging

Description:
FIELD 
     The present disclosure relates to a packaging, in particular but not exclusively to a packaging for eggs. 
     BACKGROUND 
     Egg packaging, for example an egg box, can be used to support or carry eggs. For example, egg boxes are typically used to carry eggs to and from a retail outlet. Known egg boxes are often of a paper construction and comprise a plurality of wells, in each of which an egg can be carried. 
     As will be understood, eggs are particularly susceptible to breakages if impacted by a force. This is a particular concern when in transit. Known plastic egg boxes provide little protection against breakages. Known paper egg boxes provide limited protection against breakages. Further, if an egg does break, the contents of the egg can seep into the paper packaging of the egg box, damaging the egg box such that it can no longer be used. Where paper egg boxes are stacked, such a breakage can also result in the contents of a broken egg seeping into the paper packaging of adjacent egg boxes, thereby resulting in multiple egg boxes being damaged by a single egg breakage. 
     It will be appreciated that such egg breakages and subsequent damage to egg boxes is costly, for example in terms of lost sales relating to the damaged articles and also in terms of the clean-up required. 
     It is an aim of the present disclosure to overcome or substantially reduce the problems associated with known packaging. 
     SUMMARY 
     In a first aspect an egg packaging is provided comprising a body, the body defining a cavity for receiving an egg, the cavity comprising a base and an open end, and the cavity defining a longitudinal axis extending in a direction between the base and the open end, wherein the longitudinal axis is intended to be vertical when in use, and wherein the packaging comprises one or more laterally resilient portions arranged to provide support against lateral movement of an egg in said cavity relative to the longitudinal axis. 
     Egg packaging, for example an egg box, can be used to support or carry eggs. When egg packaging containing eggs is moved or transported, for example to or from a retail outlet, such movement can result in an egg contained in the packaging rattling in the packaging. Such rattling can result in the eggs being subjected to side-on forces as the egg rattles and hits against the packaging. Similarly, if an egg packaging is dropped, the eggs inside the packaging may be impacted by side-on forces. In other words, forces side-on to the egg, that is forces lateral to a longitudinal axis of the egg. When such side-on forces are sufficiently large, impact of these side-on forces on the egg can result in breakage of the egg. 
     As described above, egg packaging disclosed herein comprises a cavity for receiving an egg and one or more laterally resilient portions which are arranged to provide support against lateral movement of the egg in the cavity, relative to the longitudinal axis of the cavity. Advantageously, as an egg rattles in the packaging and hits against the packaging the kinetic energy of the egg can be absorbed, at least partially, by the or each laterally resilient portion, thereby reducing the likelihood of damage or breakage of the egg. Consequently, the cost and clean-up associated with egg breakages is reduced. 
     In some embodiments, the or each resilient portion is configured to abut a surface of an egg occupying said cavity. In such embodiments, rattling of the egg in said cavity is minimised as the or each resilient portion supports the egg against movement and also absorbs lateral forces which would otherwise impact the egg. 
     The shape of an egg is such that it is relatively strong when subjected to end-on impacts, that is substantially longitudinal impacts relative to the longitudinal axis of the egg, and relatively weak when subjected to side-in impacts. Accordingly, providing an egg packaging having laterally resilient portions arranged to provide support against lateral movement of an egg in said cavity relative to the longitudinal axis of the cavity has the advantage of protecting eggs from side-on impacts, hence reducing the risk of damage or breakage of the egg. 
     In some embodiments, the or each laterally resilient portion is arranged to flex, thereby providing support against lateral movement of an egg in said cavity relative to the longitudinal axis. 
     In this way, side-on forces impacting the egg are absorbed by the or each laterally resilient portion, thereby reducing the likelihood of damage of breakage of the egg. 
     Providing one or more laterally resilient portions that are configured to flex also has the advantage that a greater range of egg sizes can be securely carried by the packaging. 
     Where relatively small eggs are carried by the packaging, the laterally resilient portions act to absorb side-on forces experienced by the egg and also to support the egg in the cavity, thereby preventing or substantially reducing rattling of the egg in the cavity. Where relatively large eggs are carried by the packaging, the laterally resilient portions flex or move to accommodate the egg in the cavity, whilst also absorbing side-on forces impacting the egg and supporting the egg. Accordingly, a smaller range of egg box sizes is required to carry a large range of egg sizes. 
     In some embodiments, the packaging comprises a plurality of laterally resilient portions. 
     For example, 2, 3, 4, 5 or 6 laterally resilient portions may be provided. Alternatively, any suitable number of laterally resilient portions can be used. 
     In some embodiments, the plurality of laterally resilient portions are substantially equally spaced with respect to the longitudinal axis. 
     In this way, the side-on forces can be absorbed, at least partially, from a plurality of directions, thereby providing additional protection to an egg carried in the cavity. For example, the plurality of laterally resilient portions are substantially equally spaced angularly with respect to the longitudinal axis. In this way side-on forces can be absorbed, at least partially, from a plurality of angular directions. For example, the packaging comprises four laterally resilient portions equally spaced with respect to the longitudinal axis. 
     In some embodiments, the plurality of laterally resilient portions are arranged in one or more pairs of diametrically opposed laterally resilient portions. 
     In some embodiments, the body defines a boundary in relation to said cavity, coaxial with the longitudinal axis, and wherein the or each laterally resilient portion projects towards said longitudinal axis relative to the boundary. 
     In some embodiments, the or each laterally resilient portion extends towards said longitudinal axis to abut an egg occupying in said cavity. 
     In some embodiments, the or each laterally resilient portion comprises a curved profile in a plane transverse to the longitudinal axis. 
     In some embodiments, the or each laterally resilient portion comprises a curved profile in a plane transverse to the longitudinal axis arranged such that an apex of the curved profile is provided nearmost the longitudinal axis of said cavity. 
     In this way, the or each laterally resilient portion comprises a “bowed” profile to provide a spring-like functionality. A rounded shape is particularly beneficial in terms of optimising the resilient action of the laterally resilient portion, thereby facilitating the supporting function of the laterally resilient portions. 
     It will be appreciated that other suitable profiles can also be used. For example, the laterally resilient portion may comprise a flat profile. 
     In some embodiments, the boundary is a circular boundary. In some embodiments, the boundary comprises a circular cross section. In some embodiments, the or each laterally resilient portion is bound by an arc of the circular boundary or cross section. For example, the or each resilient profile comprises a curved profile which is bound by an arc of the circular boundary or cross section. 
     For example, the curved profile projects from or intersects the arc of the circular boundary or cross section. In some embodiments, the curved profile of the laterally resilient portion extends from and is bound by an arc of the circular boundary or cross section. In some embodiments, the angle subtended by the arc is less than 90°, for example in the range of 20° to 85°, for example in the range of 30° to 70°, for example in the range of 45° to 50°, e.g. approximately 50°. 
     In some embodiments, the curved profile of the or each laterally resilient portion is shaped as an inversion of the arc about its chord. 
     In other words, the laterally resilient portion is shaped as a mirror image of the arc reflected about its chord. It will be understood that the curved profile of the or each laterally resilient portion may comprise any suitable radius of curvature such that it provides support against lateral movement of an egg in said cavity relative to the longitudinal axis. For example, the or each laterally resilient portion may comprise a radius of curvature which is larger or smaller than a radius of curvature of the boundary. 
     In some embodiments the or each laterally resilient portion extends substantially along the chord of the arc along which the laterally resilient portion is provided. In other words the laterally resilient portion comprises a flat profile. 
     In some embodiments the or each laterally resilient portion is arranged to define an arcuate profile extending in a direction away from the base of the cavity, wherein an apex of the arcuate profile is located furthermost from the longitudinal axis. Said arcuate profile can be thought of as a concave profile as viewed from the interior of the cavity. 
     In this way, the or each laterally resilient portion is shaped to compliment the profile of an egg supported by the cavity. 
     In some embodiments, at least one of said laterally resilient portions extends no further than the apex of the arcuate profile. This facilitates stacking of the boxes. 
     In some embodiments, at least one of said laterally resilient portion extends beyond the apex of the arcuate profile to project towards the longitudinal axis. 
     In other words, at least one laterally resilient portion extends in a direction away from the base, initially extending away from the longitudinal axis, following its arcuate profile. Said at least one laterally resilient portion extends following its arcuate profile beyond the apex of the arcuate profile, such that the at least one laterally resilient portion projects or extends back towards the longitudinal axis. In this way, when an egg is positioned in the cavity, additional support is provided to the egg. This supporting function provided by the arcuate laterally resilient portion, facilitates retention of the egg in the cavity and reduces the extent to which the egg is free to rattle in the packaging. 
     For example, the at least one laterally resilient portion extends to project into the cavity, e.g. over the base. 
     Advantageously, in the case where the packaging is made from a plastics material, packaging comprising one or more laterally resilient portions comprising such an arcuate profile can be produced without requiring any special tooling. For example, where at least one of the laterally resilient portions comprises an arcuate profile and is configured to project beyond the apex of the arcuate profile towards the longitudinal axis of the cavity, production of this undercut can be produced without the need for special tooling. The laterally resilient portion can simply flex out of the way when the tool is extracted. 
     In some embodiments two or more laterally resilient portions extend beyond the apex of the arcuate profile, thereby enhancing this supporting function. For example, the two or more laterally resilient portions which extend beyond their apex are diametrically opposed. 
     For example, in some embodiments, the packaging comprises a plurality of cavities configured in a square or rectangular arrangement. In such arrangements, a laterally resilient portion may be provided at a position adjacent each corner of the square or rectangular arrangement. Optionally, each of said laterally resilient portions positioned adjacent each corner extends beyond its apex. This provides additional protection against knocks received by the corners of the container. 
     In some embodiments, the packaging also comprises a lid for closing over the base. In some embodiments, the body comprises at least one stanchion extending from the body at a position between adjacent cavities and projecting towards the lid when the lid is in a closed position. Such a stanchion may be configured to abut the lid when the lid is in a closed position, thereby providing additional protection to eggs carried in the container. 
     In some embodiments, a laterally resilient portion adjacent said stanchion extends beyond its apex. In other words, said laterally resilient portion extends along a height, or length, of the stanchion. 
     In some embodiments, the body comprises a side wall extending between the base and the open end of the cavity. 
     In some embodiments, the or each laterally resilient portion is provided by a respective portion of the side wall. 
     In some embodiments, the or each laterally resilient portion is integral with the side wall. 
     Consequently, egg packaging which is relatively simple to manufacture is provided. No additional separate components are required to achieve the dampening function of the laterally resilient portion. 
     In some embodiments, the side wall is coaxial with the longitudinal axis. In some embodiments, the or each laterally resilient portion projects towards said longitudinal axis relative to said side wall. 
     In some embodiments, the side wall comprises an annular cross section. In some embodiments, the or each laterally resilient portion comprises a portion of the cavity side wall which is deformed away from the annular cross section in a direction towards the longitudinal axis. 
     In some embodiments, the side wall comprises a circular profile, e.g. a circular cross section, coaxial with the longitudinal axis. In some embodiments, the or each laterally resilient portion is bound by an arc of the circular side wall. For example, the or each laterally resilient portion comprises a curved profile which is bound by an arc of the circular side wall. 
     In some embodiments, the curved profile of the laterally resilient portion extends from and is bound by an arc of the circular side wall. In some embodiments, the angle subtended by the arc is less than 90°, for example in the range of 20° to 85°, for example in the range of 30° to 70°, for example in the range of 45° to 50°, e.g. approximately 50°. In some embodiments, the angle subtended by the arc varies along a height of the side wall, wherein the height of the side wall extends between the base and the open end of the cavity. 
     In some embodiments, the arc length of the side wall between adjacent laterally resilient portions at the open end of the cavity is 30 mm or less, for example in the range of 10 mm-20 mm, for example less than 10 mm, for example less than 5 mm, e.g. 2-3 mm. In some embodiments, the arc length between adjacent laterally resilient portions varies along the height of the side wall. For example, the arc length between adjacent laterally resilient portions proximal the base of the cavity may be less than at the open end of the cavity, for example in the range of 0-20 mm, for example 0-10 mm. 
     In some embodiments, the cavity is substantially ovoid in shape. In such embodiments, it will be appreciated that the arc length of the side wall between adjacent laterally resilient portions proximal the base of the cavity can be much less, for example in the range of 0-20 mm, for example 0-10 mm. 
     In some embodiments, the curved profile of the or each laterally resilient portion is shaped as an inversion of the arc about its chord. 
     In other words, the curved profile of the or each laterally resilient portion is shaped as a mirror image of the arc reflected about its chord. 
     It will be understood that the curved profile of the or each laterally resilient portion may comprise any suitable radius of curvature such that it provides support against lateral movement of an egg in said cavity relative to the longitudinal axis. For example, the or each laterally resilient portion may comprise a radius of curvature which is larger or smaller than a radius of curvature of the side wall. Alternatively, the or each laterally resilient portion may comprise a flat profile. 
     In some embodiments, the body comprises a slit or opening arranged to facilitate flexing of the or each laterally resilient portion. 
     By providing a slit or opening in the body, flexing of the or each laterally resilient portion provided by said side wall is facilitated. This is particularly advantageous where the or each laterally resilient portion is integrally formed with the side wall of the cavity. In some embodiments the slit or opening defines at least a part of the or each laterally resilient portion. 
     In some embodiments, the slit or opening is provided adjacent the open end of the cavity and/or along at least a portion of a length of the side wall extending between the base and the open end of the cavity. 
     Such slits or openings facilitate flexing of the or each laterally resilient portion when subjected to a force from an egg hitting against the laterally resilient portion. In some embodiments, a slit or opening is provided proximal the cavity base. 
     Optionally, said slit or opening is provided proximal the cavity opening. In some embodiments, said slit or opening is provided closer to the cavity opening than the cavity base. In this way, should an egg occupying said cavity break, the contents of the egg is less likely to spill through the slit or opening. 
     In some embodiments, the or each laterally resilient portion comprises a finger extending from proximal the base of the cavity. In some embodiments, the finger is defined by a continuous slit provided in the side wall of the cavity. For example, the slit is arranged to extend along a first length in a direction towards the open end of the cavity, across a portion of the side wall adjacent the cavity opening, and along a second length of the side wall in a direction towards the base of the cavity. 
     In some embodiments, the or each laterally resilient portion comprises a convex portion projecting towards the longitudinal axis. 
     In some embodiments, the or each laterally resilient portion comprises a convex portion or dome-shaped portion arranged such that an apex of the dome or convex portion is provided nearmost the longitudinal axis of the cavity. For example, the convex or dome shaped portion may be provided proximal the open mouth of the cavity. 
     The curvature of the convex or dome shaped portion enables this portion to deflect away from the longitudinal axis. Accordingly, when an egg is introduced into the cavity, this portion deflects away from the longitudinal axis to accommodate the egg. The convex or domed portion is resilient such that, when the egg is removed from the cavity, the convex portion springs back to its original shape. In this way, absorption of lateral forces impacting on the egg is facilitated. Advantageously, the convex or dome shaped portion is configured to deflect without requiring a slit or opening in the body of the egg packaging. 
     In some embodiments, the or each laterally resilient portion comprises a resilient finger projecting in a direction away from the base of the cavity. For example, in some embodiments, the or each laterally resilient portion comprises a resilient finger extending from the base of the cavity. 
     In some embodiments, the or each laterally resilient portion comprises a series of resilient sub-portions. 
     In some embodiments, the or each laterally resilient portion is configured to abut a surface of an egg occupying said cavity. In this way, rattling of the egg in said cavity is minimised as the or each resilient portion supports the egg against movement and also absorbs lateral forces which would otherwise impact the egg. 
     In some embodiments, the body comprises one or more longitudinally resilient portions arranged to provide support against longitudinal movement of an egg in said cavity relative to said longitudinal axis. 
     In this way, an egg occupying the cavity of the body is protected and supported against end-on impacts relative to said longitudinal axis, hence reducing the risk of damage or breakage of the egg. In other words, the or each longitudinally resilient portion acts to dampen end-on forces impacted on an egg occupying the cavity. 
     As described above, when transporting or moving eggs contained in egg packaging, e.g. an egg box, movement in transit can result in the eggs rattling in the packaging. This can result in the eggs being subjected to end-on impacts. Similarly, if an egg packaging is dropped, end-on forces may impact on eggs inside the packaging. 
     When such end-on forces are sufficiently large, this can result in breakage of the egg. By providing one or more longitudinally resilient portions, at least a portion of the kinetic energy of the egg as it hits against the packaging is absorbed, reducing the likelihood of damage or breakage of the egg. Consequently, the cost and clean-up associated with egg breakages is reduced. 
     In a second aspect an egg packaging is provided comprising a body, the body defining a cavity for receiving an egg, the cavity comprising a base and an open end, and the cavity defining a longitudinal axis extending in a direction between the base and the open end, wherein the longitudinal axis is intended to be vertical when in use, and wherein the packaging comprises one or more longitudinally resilient portions arranged to provide support against longitudinal movement of an egg in said cavity relative to the longitudinal axis. 
     In some embodiments, the or each longitudinally resilient portion is configured to flex to provide support against longitudinal movement of an egg in said cavity relative to the longitudinal axis. 
     This has an advantage that a greater range of egg sizes can be securely carried by the packaging. Where relatively small eggs are carried by the packaging, the longitudinally resilient portions act to absorb end-on forces experienced by the egg and also to support the egg in the cavity, thereby preventing or substantially reducing rattling of the egg in the cavity. Where relatively large eggs are carried by the packaging, the longitudinally resilient portions flex or move to accommodate the egg in the cavity, whilst also absorbing end-on forces impacting the egg and supporting the egg. Accordingly, a smaller range of egg box sizes is required to carry a large range of egg sizes. 
     In some embodiments, at least one of the or each longitudinally resilient portion is provided by the base of said cavity and projects towards said cavity. 
     In this way, end-on forces impacting on the egg are absorbed by the base, reducing the likelihood of damage or breakage of the egg. 
     In some embodiments, the or each longitudinally resilient portion is integral with said base. 
     Consequently, egg packaging which is relatively simple to manufacture is provided. No additional separate components are required to achieve the dampening function of the longitudinally resilient portion. 
     In some embodiments, the or each longitudinally resilient portion is substantially dome-shaped, such that an apex of the dome is nearmost the cavity. 
     In this way, the longitudinally resilient portion projects towards an egg occupying said cavity, for example, said longitudinally resilient portion abuts said egg. 
     In some embodiments, the or each longitudinally resilient portion comprises a central depression at the apex of the dome-shape, configured to receive a portion of an egg. 
     In this way, an egg can be properly located in position in the cavity of the packaging. For example, the egg can be positioned such that the side surface of the egg is optimally aligned with the laterally resilient portions. 
     In some embodiments, the or each longitudinally resilient portion comprises at least one channel and/or ridge concentric with the apex of the dome. 
     This arrangement facilitates flexing of the base and therefore facilitates absorption of end-on forces impacting an egg occupying said cavity, for example due to the egg rattling in the packaging and impacting the base. In this way, the likelihood of damage to or breakage of the egg is reduced. The arrangement of one of more concentric channels facilitates the resilient spring action of the longitudinally resilient portion. 
     In some embodiments, a plurality of channels are provided, each of which being concentric to the apex of the dome. 
     In this way, increased overall flex in the longitudinally resilient portion is provided. 
     In some embodiments, the or each substantially dome-shaped longitudinally resilient portion comprises a circular perimeter defining a ring arranged to form a foot on which the egg packaging can rest. For example, a circular edge is defined where the base meets the side wall of the cavity. In this way, a rigid ring is provided on which the packaging can rest. This circular base is inherently strong and so further protects an egg in the cavity against impacts. 
     In some embodiments, the or each longitudinally resilient portion comprises a plurality of resilient fingers projecting towards the cavity relative to said base and configured to abut a portion of an egg located in said cavity to provide support against longitudinal movement of an egg in said cavity relative to the longitudinal axis. For example, the plurality of resilient fingers extend from the base and are configured to abut a portion of an egg located in said cavity. 
     In some embodiments, the egg packaging comprises the body having said cavity, and a lid coupled to the body, wherein at least one of the or each longitudinally resilient portions is provided by the lid. 
     In this way, an egg occupying the cavity of the packaging is protected from end-on impacts in the direction of the lid of the packaging, hence reducing the risk of damage to or breakage of the egg. In other words, the lid acts to dampen end-on forces impacting on an egg in the cavity. 
     As described above, when transporting eggs, movement in transit can result in the eggs rattling in the egg packaging. This can result in end-on forces impacting the eggs. Similarly, if an egg packaging is dropped, end-on forces may impact eggs inside the packaging. When such forces are sufficiently large, this can result in breakage of the egg. Accordingly, by providing a resilient and dampening lid, at least some of the kinetic energy of the egg as it hits against the lid of the packaging is absorbed, reducing the likelihood of damage to or breakage of the egg. Consequently, the cost and clean-up associated with egg breakages is reduced. 
     In some embodiments, the lid and base of the container are coupled via a hinge, for example a live hinge which acts to bias the lid towards an open position. 
     In some embodiments, the or each longitudinally resilient portion is integral with said lid. 
     In some embodiments, the or each longitudinally resilient portion comprises one or more resilient fingers extending from the lid towards the cavity, when the lid is closed. 
     For example, 2, 3, 4, 5, 6 or more resilient fingers may be provided. In such embodiments, an exterior surface of the lid is unaltered by the resilient fingers extending from an interior surface of the lid. Accordingly a flat uninterrupted exterior lid surface is provided. This is advantageous for the application of labelling to the container, for example, by in-mould labelling. 
     In some embodiments, each longitudinally resilient portion comprises four resilient fingers arranged as two pairs of diametrically opposed fingers. In some embodiments, the four resilient fingers are equally spaced with respect to the longitudinal axis, when the lid is in the closed position. In other words, each resilient finger in the set of four is equidistant from the longitudinal axis. 
     In some embodiments, each resilient finger comprises a curved profile such that the resilient finger extends away from the longitudinal axis when the lid is closed. 
     For example, in some embodiments the fingers are curved such that diametrically opposed pairs of resilient fingers extend away from each other. In this way, the resilient fingers are arranged to abut an egg in a corresponding cavity when the lid is closed. Alternatively, if a comparatively small egg is located in the cavity, the resilient fingers may not abut the surface of the egg. 
     The curved profile of each resilient finger facilitates flexing of the resilient finger when a longitudinal force relative to the longitudinal axis of the respective cavity is applied. 
     In some embodiments, the resilient fingers are configured to flex away from the longitudinal axis. In other words, the resilient fingers are configured to flex such that each resilient finger of a diametrically opposed pair is configured to flex away from the other resilient finger of the pair. 
     In some embodiments, the or each longitudinally resilient portion is substantially dome-shaped, such that an apex of the dome is nearmost the cavity. 
     In some embodiments, the or each longitudinally resilient portion comprises a central depression at the apex of the dome-shape, configured to receive a portion of an egg in said cavity. 
     In some embodiments, the or each longitudinally resilient portion comprises at least one channel and/or ridge concentric with the apex of the dome. 
     In some embodiments, a plurality of channels are provided, each of which being concentric to the apex of the dome. 
     In some embodiments, a first longitudinally resilient portion is provided by the base and a second longitudinally resilient portion is provided by the lid. 
     In some embodiments, a single longitudinally resilient portion is provided by the base and/or the lid. For example, a single longitudinally resilient portion is provided by the base and/or the lid per cavity of the packaging. 
     In some embodiments, the egg packaging comprises the body having a cavity, and a lid coupled to the body. 
     In some embodiments, the body comprises a plurality of cavities for receiving an egg, each cavity comprising a base and an open end, and each cavity defining a longitudinal axis extending in a direction between the base and the open end, wherein the longitudinal axes are intended to be vertical when in use. 
     In some embodiments, the base comprises a ring projecting from the body, arranged to form a foot upon which the egg packaging can rest. 
     In some embodiments, the base comprises a circular perimeter and the ring projects from the circular perimeter of the base. 
     In some embodiments, the egg packaging is formed of a plastics material. 
     Use of a plastics material is easier to wipe clean compared to traditional paper egg boxes. Therefore, in the case where an egg breakage occurs, an egg packaging of plastics construction can be wiped clean and reused. In addition, the broken egg is more likely to remain within the packing and not seep out of the packaging, which can result in damage to neighbouring packaging, as can be the case with conventional paper egg boxes. 
     The use of plastics material, for example instead of a paper based material, is particularly advantageous in enabling the thickness of the material used to be reduced. 
     This has the benefit of enabling closer stacking of the egg packaging, consequently, a greater number of egg boxes can be transported in a given volume of space, for example in a vehicle. 
     In some embodiments, the container is formed of polypropylene. 
     In some embodiments, the egg packaging can be formed from foamed plastics, paper, card, papier-mâché, or any other suitable material. 
     In some embodiments, at least a portion of the or each longitudinally resilient portion comprises a reduced thickness as compared to at least a portion of the remainder of the egg packaging. 
     By reducing the thickness of at least a portion of the or each longitudinally resilient portion, flexing of the or each longitudinally resilient portion is facilitated. In some embodiments, the or each longitudinally resilient portion has a reduced thickness as compared to at least a portion of the remainder of the packaging, e.g. the side wall of the cavity. For example, the thickness of the of the narrowest portion of the or each longitudinally resilient portion is in the range of 0.2 mm to 1 mm, for example in the range of 0.2 mm to 0.7 mm, for example in the range of 0. mm to 0.5 mm, for example in the range of 0.25 to 0.4 mm, for example in the range of 0.25 to 0.3 mm. 
     In some embodiments, the thickness of the longitudinally resilient portion gradually reduces, such that the region of most reduced thickness is proximal the longitudinal axis. 
     In some embodiments, at least a portion of the longitudinally resilient portion and at least a portion of the remainder of the egg packaging, e.g. the side wall, have the same thickness. 
     In some embodiments, at least a portion of the or each laterally resilient portion comprises a reduced thickness as compared to at least a portion of the remainder of the egg packaging. 
     By reducing the thickness of at least a portion of the or each laterally resilient portion, flexing of the or each laterally resilient portion is facilitated. In some embodiments, the or each laterally resilient portion has a reduced thickness as compared to at least a portion of the remainder of the packaging, e.g. the side wall of the cavity. For example, the thickness of the or each laterally resilient portion is in the range of 0.2 mm to 1.0 mm, for example in the range of 0.2 mm to 0.7 mm, for example in the range of 0.2 mm to 0.5 mm, for example in the range of 0.25 mm to 0.4 mm, for example in the range of 0.25 mm to 0.3 mm. 
     In a third aspect an egg packaging comprising a body is provided, the body defining a cavity supporting an egg, the cavity comprising a base and an open end, and the cavity defining a longitudinal axis extending in a direction between the base and the open end, wherein the longitudinal axis is intended to be vertical when in use, and wherein the packaging comprises one or more laterally resilient portions arranged to provide support against lateral movement of the egg in said cavity relative to the longitudinal axis. 
     In a fourth aspect an egg packaging comprising a body is provided, the body defining a cavity supporting an egg, the cavity comprising a base and an open end, and the cavity defining a longitudinal axis extending in a direction between the base and the open end, wherein the longitudinal axis is intended to be vertical when in use, and wherein the packaging comprises one or more longitudinally resilient portions arranged to provide support against longitudinal movement of the egg in said cavity relative to the longitudinal axis. 
     It will be appreciated that the optional features described may apply to any aspect disclosed herein. All combinations contemplated are not recited explicitly for the sake of brevity.

     DETAILED DESCRIPTION 
     With reference to  FIG. 1 , an egg packaging, for example an egg box, is generally indicated at reference numeral  2 . The egg packaging  2  comprises a lid  3  coupled to a body  4  by a hinge  5 . For example, the hinge  5  may be a live hinge. In some embodiments, the hinge  5  is configured such that the lid  3  and body  4  can lie substantially flat when the lid is open, thereby facilitating stacking of the egg boxes  2 . 
     The body  4  defines a plurality of cavities  6 , each of which being arranged to receive an egg. In the illustrated embodiments, the body  4  defines six cavities  6  provided in a rectangular arrangement. It will be understood that any number of cavities  6  can be provided in the body  4 , for example 1, 2, 4, 6, 8, 10, 12, 18, 24 or more cavities may be provided. 
     The lid  3  is configured to be moved between an open position (as shown in  FIG. 1 ) in which eggs occupying the cavities  6  can be accessed, and a closed position, in which the lid  3  extends across the body  4  of the packaging  2  to cover the eggs, thereby protecting the eggs. 
     As can be seen in  FIGS. 3 and 4 , each cavity  6  comprises a base  8 , an open end  10  and a longitudinal axis A extending in a direction between the base  8  and the open end  10 . When the egg packaging  2  is in use, in other words when eggs are carried in one or more of the plurality of cavities  6 , the longitudinal axis A is intended to be substantially vertical. 
     The egg packaging  2  comprises a plurality of laterally resilient portions  12  which are configured to provide support against lateral movement of an egg occupying a cavity  6 , said lateral movement being lateral relative to the longitudinal axis A. In other words, the laterally resilient portions  12  provide support against substantially sideways movement of an egg in said cavity  6 . 
     In the illustrated embodiments each cavity  6  is provided with four laterally resilient portions  12 . With respect to a given cavity  6 , each of the laterally resilient portions  12  is configured to flex in order to provide support against lateral movement of an egg in the cavity  6 , relative to the longitudinal axis A. Each of the laterally resilient portions  12  is configured to flex such that, when a lateral force is applied to the portion  12 , for example by an egg in the cavity  6 , the laterally resilient portion  12  is moved in a direction away from the cavity  6 , i.e. away from the longitudinal axis A. In this way, the lateral force is absorbed by the laterally resilient portion  12 . 
     When the laterally resilient portion  12  is no longer subjected to a lateral force, the portion  12  springs back towards the cavity  6 , i.e. towards the longitudinal axis A, into its original position. 
     As can be clearly seen in  FIGS. 5 and 6 , the laterally resilient portions  12  of a given cavity  6  are substantially equally spaced around the cavity  6  with respect to the longitudinal axis A. Furthermore, the laterally resilient portions  12  are arranged in pairs such that the laterally resilient portions  12  of each pair are diametrically opposed. 
     In the illustrated embodiments, each cavity  6  of the body  4  includes a side wall  16  extending between the base  8  and the open end  10  of the cavity  6 . In other words, each cavity  6  is partially defined by a side wall  16  extending between the base  8  and the open end  10  of the cavity  6 . 
     As is illustrated in  FIG. 5 , the side wall  16  of each cavity  6  defines a boundary  14  in relation to the cavity  6 . Said boundary  14  is co-axial with the longitudinal axis A. Each of the laterally resilient portions  12  of a given cavity  6  is arranged to project towards the longitudinal axis A relative to the boundary  14 . In alternative embodiments, the boundary  14  may be defined by means other than the cavity side wall  16 . 
     With particular reference to  FIGS. 5 and 6 , each laterally resilient portion  12  includes a curved profile  18  in a plane transverse to the longitudinal axis A of the respective cavity  6 , for example in a plane perpendicular to the longitudinal axis A. Said curved profile  18  of each laterally resilient portion  12  is positioned such that an apex  18   a  of the curved profile  18  is provided nearmost the longitudinal axis A of the respective cavity  6 . In other words, the curved profile of the laterally resilient portion  12  is curved towards the respective cavity  6  such that the apex  18   a  is provided closer to the longitudinal axis A than the remainder of the curved profile  18 . As can be seen in  FIGS. 5 and 6  in particular, this arrangement provides a “bowed” profile, such that the laterally resilient portions  12  have a spring-like functionality. 
     Again with reference to  FIG. 5 , for a given cavity  6 , the boundary  14  defined by the sidewall  16  is a substantially circular boundary  14 , coaxial with the longitudinal axis A. The laterally resilient portions  12  of the cavity  6  are formed from a portion of the cavity sidewall  16 , which is deformed away from the circular boundary  14  in a direction towards the longitudinal axis A. In other words, the sidewall  16  comprises a substantially circular cross section, wherein the laterally resilient portions  12  are deformed away from this circular cross section towards the longitudinal axis A. 
     The curved profile  18  of each of the laterally resilient portions  12  is bound by an arc  20  of the circular boundary  14 . Further, the curved profile  18  of the laterally resilient portions  12  is shaped as an inversion or mirror image of the arc  20  about its chord  22 . In the embodiment illustrated in  FIGS. 5 and 6 , the angle subtended by the arc  20  proximal the open end  10  of the cavity is approximately 50°. However, it will be understood that other suitable angles may be used. Due to the shape of the cavity  6 , it will be appreciated that the angle subtended by the arc proximal the base  8  of the cavity  6  may be different. 
     The arc length of the side wall  16  between adjacent laterally resilient portions  12  at the open end  10  of the cavity  6  is in the range of 10 mm-20 mm. However, it will be understood that other suitable arc lengths may be used. Due to the shape of the cavity  6 , it will be appreciated that the arc length of the side wall  16  between adjacent laterally resilient portions  12  proximal the base  8  of the cavity  6  can be much less, for example in the range of 0-20 mm, for example 0-10 mm. 
     With reference to  FIG. 4 , the laterally resilient portions  12  of a given cavity  6  are arranged to define an arcuate profile  24  which extends in a direction away from the base  8  of the cavity  6 . The arcuate profile  24  of each laterally resilient portion  12  is arranged such that an apex  24   a  of the arcuate profile  24  is located furthermost from the longitudinal axis A. In other words, the arcuate profile  24  extends such that its apex  24   a  is located further away from the longitudinal axis A than the remainder of the arcuate profile  24 . In this way, a cavity  6  which is substantially ovoid is provided. In other words, the cavity  6  is shaped to approximately correspond to the shape of an egg. 
     As can be seen in  FIG. 1 , the lid  3  comprises a cover portion  48  and a side wall  50 . The side wall  50  is arranged to extend from the cover portion  48  towards the body  4  of the egg packaging  2 , when the lid  3  is in the closed configuration. A portion of the side wall  50  of the lid  3  is coupled to the body  4  by a hinge  5 . 
     The cover portion  48  has an inner cover surface  52 , which faces towards the body  4  when the lid  3  is closed, and an outer cover surface  54 , which faces away from the body  4  when the lid  3  is closed. 
     The packaging  2  of the illustrated embodiments comprises six cavities  6  configured in a rectangular arrangement, such that the packaging body  4  has four corners  28 . As illustrated in  FIGS. 1-3 , the body  4  includes a pair of stanchions  26  extending from the body  4  at a position between adjacent cavities  6 , for example extending from a central position between groups of four cavities  6 . The stanchions  26  are configured to abut the inner cover surface  52  of the lid  3  when the lid  3  is closed. In this way additional strength and support against impacts to the lid  3  of the packaging  2  is provided, reducing the likelihood of damage to eggs contained in the packaging  2 . 
     With reference to  FIGS. 1-3 , the laterally resilient portions  12  which are provided adjacent the corners  28  of the body  4  are each arranged to extend to a height beyond the apex  24   a  of its arcuate profile  24 . In this way, the laterally resilient portions  12  provided at the body corners  28  project towards the longitudinal axis A, in other words towards the cavity  6 . 
     Similarly, laterally resilient portions  12  provided adjacent a stanchion  26  are arranged to extend to a height along the stanchion  26 , such that the laterally resilient portion  12  extends beyond the apex  24   a  of its arcuate profile  24 . In this way, the laterally resilient portions  12  provided adjacent the stanchions  26  project towards the longitudinal axis A, in other words towards the cavity  6 . 
     Consequently, the laterally resilient portions provided adjacent the corners  28  and stanchions  26  of the body  4  act to retain eggs contained in the respective cavities  6  by providing a “gripping” action e.g. by projecting over the widest part of the egg. 
     The remaining laterally resilient portions  12 , i.e. those not adjacent a corner  28  or stanchion  26  of the body  4 , are provided such that the portions  12  extend from the base no further than the apex  24   a  of its arcuate profile  24 . In other words, the cavity opening  10  in the region of these laterally resilient portions is provided at a location which is positioned along the arcuate profile no further than the apex  24   a  of the arcuate profile  24 . 
     In alternative embodiments, the body  4  may comprise laterally resilient portions  12  arranged such that all of the laterally resilient portions  12  extend from the base no further than the apex  24   a  of its arcuate profile  24 . Alternatively, other combinations of laterally resilient portions  12  having a variety of heights can be used. 
     As is shown in  FIGS. 1-4 , a slit  30  is provided in the body  4 , adjacent each laterally resilient portion  12  and proximal the open end  10  of the cavity  6 , in an upper surface  70  of the body  4 . By providing a slit  30  in the body  4  of the packaging  2 , flexing of the laterally resilient portions  12  is facilitated. In some embodiments, a slit  30  is also provided proximal the base of the cavity  6 , again to facilitate flexing of the laterally resilient portions  12 . This is illustrated in  FIG. 13 . 
     The egg packaging  2  is formed from a plastics material, for example polypropylene. In alternative embodiments, the egg packaging can be formed from foamed plastics, paper, card, papier-mâché, or any other suitable material. 
     The thickness of the plastics material from which the egg packaging is formed is typically in the range of 0.4-1.0 mm, for example 0.4-0.7 mm, for example 0.4-0.5 mm. Accordingly, the side wall  16  of the respective cavities has a thickness in the range of 0.4-1.0 mm, for example 0.4-0.7 mm, for example 0.4-0.5 mm. 
     The use of plastics material, for example instead of a paper based material, is particularly advantageous in enabling the thickness of the material used to be reduced. This has the benefit of enabling closer stacking of the egg packaging, consequently, a greater number of egg boxes can be transported in a given volume of space, for example in a vehicle. 
     At least a portion of each laterally resilient portion  12  comprises a reduced thickness compared to at least a portion of the remainder of the egg packaging. In the illustrated embodiments, each laterally resilient portion  12  comprises a reduced thickness as compared to the side wall  16  of the respective cavity  6 . By reducing the thickness of the laterally resilient portion  12 , flexing of the laterally resilient portion  12  is facilitated. For example, the thickness of the or each laterally resilient portion is in the range of 0.2 mm to 1.0 mm, for example in the range of 0.2 mm to 0.7 mm, for example in the range of 0.2 mm to 0.5 mm, for example in the range of 0.25 to 0.4 mm, for example in the range of 0.25 to 0.3 mm. 
     In some embodiments, the laterally resilient portions  12  and at least a portion of the remainder of the egg packaging, e.g. the side wall  16 , have the same thickness. 
     In the illustrated embodiments, the base  8  of each cavity  6  is provided with a longitudinally resilient portion  32  which is arranged to provide support against longitudinal movement of an egg occupying the cavity  6 , relative to said longitudinal axis A. As will be described in more detail below, the longitudinally resilient portion  32  is configured to flex in order to support an egg against longitudinal movement in the cavity  6 . The longitudinally resilient portion  32  is integrally formed with the base  8  and is arranged to project towards said cavity  6 . 
     The longitudinally resilient portion  32  of the illustrated embodiments is substantially dome-shaped such that an apex of the dome is nearmost the cavity  6 . As can be seen in  FIG. 7 , the apex of the dome-shaped portion  32  includes a central depression  36  which is shaped to receive an end portion of an egg  68 . The longitudinally resilient portion  32  also includes a channel  38  and corresponding ridge  40  (as viewed from the interior of the cavity  6 ), wherein the channel  38  and ridge  40  are concentric with the apex of the dome-shaped portion  32 . 
       FIG. 7  shows a first embodiment of the longitudinal resilient portion  32  comprising a single channel  38  and corresponding ridge  40 .  FIG. 8  shows a second embodiment of the longitudinally resilient portion  32 , which also comprises a single channel  38  and corresponding ridge  40 .  FIG. 8  shows a third embodiment of the longitudinally resilient portion  32  including two channels  38  and two corresponding ridges  40 . Any number of channels  58  and/or ridges  60  may be used, e.g. 1, 2, 3, or 4. 
     The longitudinally resilient portion  32  of each cavity  6  is configured to flex such that, when a longitudinal force is applied to the portion  32 , for example by an egg  68  in the cavity  6 , the longitudinally resilient portion  32  is moved in a direction away from the cavity  6 . In this way, the longitudinal force is absorbed by the longitudinally resilient portion  32 . The arrangement of the concentric channel(s)  38  and corresponding ridge(s)  40  facilitates this flexing. 
     When the longitudinally resilient portion  32  is no longer subjected to a longitudinal force, the portion  32  springs back towards the cavity  6 , i.e. towards the longitudinal axis A, into its original position. 
     It is believed that by increasing the number of channels  38  and ridges  40 , the overall flex in the longitudinally resilient portion  32  is increased. 
     In each of the embodiments illustrated in  FIGS. 7-9 , the dome-shaped portion  32  includes a circular perimeter defining a ring  42 . The circular perimeter of the dome-shaped portion  32  is provided where the base  8  meets the side wall  16  of the cavity  6 . This provides a rigid ring  42  which is inherently strong and so provides further protection against impacts to an egg  68  in the cavity  6 . The ring  42  is also arranged to form a foot on which the egg packaging  2  can rest. 
     At least a portion of the longitudinally resilient portion  32  comprises a reduced thickness as compared to at least a portion of the remainder of the egg packaging  2 . In the illustrated embodiments, at least a portion of the longitudinally resilient portion  32  comprises a reduced thickness compared to the side wall  16  of the cavity  6 . In the illustrated embodiments, the thickness of the longitudinally resilient portion  32  gradually reduces between its circular perimeter  42  and its apex, such that the region of most reduced thickness is at the apex. This is shown in  FIGS. 7 to 9 . 
     By reducing the thickness of at least a portion of the longitudinally resilient portion  32 , flexing of the longitudinally resilient portion  32  is facilitated. For example, the thickness of the narrowest portion of the of the longitudinally resilient portion is in the range of 0.2 mm to 1.0 mm, for example in the range of 0.2 mm to 0.7 mm, for example in the range of 0.2 mm to 0.5 mm, for example in the range of 0.25 to 0.4 mm, for example in the range of 0.25 to 0.3 mm. 
     In some embodiments, at least a portion of the longitudinally resilient portion  32  and at least a portion of the remainder of the egg packaging, e.g. the side wall  16 , have the same thickness. 
     When the egg packaging  2  is in use, an egg  68  is introduced into at least one of the cavities  6 . In the case where the egg is sufficiently large, as the egg is introduced into the cavity  6 , the surface of the egg  68  comes into contact with the laterally resilient portions  12  of the cavity  6 . The laterally resilient portions  12  flex away from the cavity  6  as the egg  68  is moved into the cavity  6 , thereby accommodating the egg  68 . 
     The egg  68  is located in the cavity  6  such that an end of the egg  68  rests in the central depression  36  of the dome-shaped longitudinally resilient portion  32  provided in the base of the cavity  6 . 
     When the egg  68  is in position in the cavity  6 , the laterally resilient portions  12  abut the surface of the egg, as can be seen in  FIGS. 7 to 9 . Alternatively, if the egg is relatively small, it may be that none of the laterally resilient portions  12 , or only some of the laterally resilient portions  12 , abut the surface of the egg. In this way, the egg packaging  2  is configured to accommodate eggs of a range of sizes. 
     Once the egg has been positioned in the cavity of the egg packaging, the lid  3  is closed over the body  4 , hence over the egg. 
     As the egg packaging  2  is carried or otherwise moved or transported, the egg  68  is supported against lateral movement in the cavity  6  by the laterally resilient portions  12 . When the egg packaging  2  is impacted by a lateral force, eggs carried by the egg packaging  2  are supported against lateral movement by the laterally resilient portions  12 . 
     When the egg packaging  2  is subjected to a lateral force, an egg  68  in one of the cavities  6  may be forced against the sides of the cavity  6 . In this way, the egg  68  applies a lateral force to the laterally resilient portions  12  of the cavity  6 . As described above, each of the laterally resilient portions  12  is configured to flex such that, when an egg  68  applies a lateral force to the laterally resilient portion  12 , the laterally resilient portion  12  is moved in a direction away from the cavity  6 , i.e. away from the longitudinal axis A. In this way, the lateral force is absorbed, at least partially, by the laterally resilient portion  12 . When the laterally resilient portion  12  is no longer subjected to a lateral force, the portion  12  springs back towards the cavity  6 , i.e. towards the longitudinal axis A, into its original position. 
     Therefore the likelihood of breakage of the egg from side-on impact is reduced, since such forces are absorbed, at least partially, by the laterally resilient portions  12  by flexing of these portions. 
     In addition, the egg  68  is supported against longitudinal movement in the cavity  6  relative to the longitudinal axis A by the longitudinally resilient portion  32  of the base  8 . When the egg packaging  2  is subjected to a longitudinal force, an egg  68  in the cavity  6  may be forced against the base  8  of the cavity  6 . In this way, the egg  68  applies a longitudinal force to the longitudinally resilient portion  32  of the cavity  6 . As described above, the longitudinally resilient portion  32  is configured to flex such that, when the egg  68  applies a longitudinal force to the portion  32 , the longitudinally resilient portion  32  is moved in a direction away from the cavity  6 . In this way, the longitudinal force is absorbed, at least partially, by the longitudinally resilient portion  32 . 
     When the longitudinally resilient portion  32  is no longer subjected to a longitudinal force, the portion  32  springs back towards the cavity  6 , into its original position. 
     Therefore the likelihood of breakage of the egg from end-on impact is reduced, since such forces are absorbed by the longitudinally resilient portion  32  by flexing of this portion  32 . 
     When an egg  68  is removed from the cavity  6 , the laterally resilient portions  12  flex away from the cavity  6  to enable the egg  68  to be removed. Alternatively, if the egg  68  is relatively small, it may be that none of the laterally resilient portions  12  abut the surface of the egg and so the egg  68  can simply be removed. 
     In some embodiments, the lid  28  is provided with a series of additional or second longitudinally resilient portions  44 , such that each cavity  6  is provided with a first longitudinally resilient portion  32  in the base  8  and a corresponding second longitudinally resilient portion  44  provided by the lid  3 . Each second longitudinally resilient portion  44  is provided integrally with the cover  48  of the lid  3 . In the embodiment of  FIG. 10 , each second longitudinally resilient portion  44  is in the form of a plurality of resilient fingers  46 . 
     The plurality of resilient fingers  46  extend from the inner cover surface  52  of the lid  3 . In the illustrated embodiment, each second longitudinally resilient portion  44  includes four resilient fingers  46  arranged as two pairs of diametrically opposed fingers  46 . Each set of four resilient fingers  46  is equally spaced with respect to the longitudinal axis A of the respective cavity  6 , when the lid is in the closed position. In other words, each resilient finger  46  in the set of four is equidistant from the longitudinal axis A. 
     As can be seen from  FIG. 11 , the plurality of resilient fingers  46  extend from the inner cover surface  52  such that the outer cover surface  54  remains flat. In this way, application of labelling to the container, for example by in-mould labelling, is facilitated. 
     Each resilient finger  46  is curved such that diametrically opposed pairs of resilient fingers  46  extend away from each other. In other words, each resilient finger  46  is curved such that it extends away from the longitudinal axis A. In this way, the resilient fingers  46  are arranged to abut an egg  68  in a corresponding cavity  6  when the lid  3  is closed. This is shown in  FIG. 11 . Alternatively, if a comparatively small egg is located in the cavity  6 , the resilient fingers  46  may not abut the surface of the egg. 
     The curved profile of each resilient finger  46  facilitates flexing of the resilient finger  46  when a longitudinal force relative to the longitudinal axis A of the respective cavity  6  is applied. The resilient fingers  46  are configured to flex away from the longitudinal axis A. In other words, the resilient fingers  46  are configured to flex such that each resilient finger  46  of a diametrically opposed pair is configured to flex away from the other resilient finger  46  of the pair. 
     In use, when the egg packaging is subjected to a longitudinal force, an egg  68  in the cavity  6  may be forced against the lid  3  of the cavity  6 . In this way, the egg  68  applies a longitudinal force to the longitudinally resilient portion  44  of the lid  3  corresponding to the cavity  6  in which the egg  68  is located, i.e. to the four resilient fingers  46  corresponding to the cavity  6 . As described above, the resilient fingers  46  are configured to flex such that, when the egg  68  applies a longitudinal force to the resilient fingers  46 , the resilient fingers  46  flex away from the longitudinal axis A. In this way, the longitudinal force is absorbed, at least partially, by the resilient fingers  46 . 
     When the resilient fingers  46  are no longer subjected to a longitudinal force, the fingers  46  spring back towards the longitudinal axis A, into the original position. 
     Accordingly, by providing a first longitudinally resilient portion  32  in the base  8  and a second longitudinally resilient portion  44  in the lid for each cavity  6 , an egg  68  in the cavity  6  is supported against longitudinal movement both in the direction of the lid  3  and in the direction of the base  8 . 
       FIG. 12  illustrates an alternative embodiment of a longitudinally resilient portion  44  provided in the lid  3 . In this embodiment, the second longitudinally resilient portion  44  is integrally provided with the lid  28 . As will be appreciated from  FIG. 12 , the second longitudinally resilient portion  44  is substantially the same as the first longitudinally resilient portion  32 . 
     As with the first longitudinally resilient portion  32 , the second longitudinally resilient portion  44  is substantially dome-shaped such that an apex of the dome is provided nearmost the corresponding cavity  6 . Each of the second longitudinally resilient portions  44  includes a central depression  56  which is shaped to receive an end portion of an egg  68  positioned in a cavity  6  when the lid  3  is in the closed position. 
     The second longitudinally resilient portion  44  shown in  FIG. 12  includes a pair of channels  58  and a pair of corresponding ridges  60  (as viewed from the interior of the cavity  6 ), wherein the channels  58  and ridges  60  are concentric with the apex of the dome-shape of the second longitudinally resilient portion  44 . As with the first longitudinally resilient portion  32 , a number of different profiles is possible. In some embodiments, a single channel  58  and ridge  60  may be provided. For example, profiles similar to those shown in  FIGS. 7, 8 and 9  can be used. It will be understood that any suitable profile may be used to provide the second longitudinally resilient portions  44 , for example, any number of channels  58  and/or ridges  60  may be used, e.g. 1, 2, 3, or 4. 
     At least a portion of the second longitudinally resilient portion  44  comprises a reduced thickness compared to at least a portion of the remainder of the egg packaging. In the illustrated embodiments, second longitudinally resilient portion  44  comprises a reduced thickness as compared to the cover portion  48  of the lid  3 . In the illustrated embodiments, the thickness of the second longitudinally resilient portion  44  gradually reduces between the perimeter of the dome-shape and its apex, such that the region of most reduced thickness is at the apex. 
     By reducing the thickness of at least a portion of the second longitudinally resilient portion  44 , flexing of the second longitudinally resilient portion  44  is facilitated. For example, the thickness of the narrowest portion of the second longitudinally resilient portion is in the range of 0.2 mm to 1.0 mm, for example in the range of 0.2 mm to 0.7 mm, for example in the range of 0.2 mm to 0.5 mm, for example in the range of 0.25 to 0.4 mm, for example in the range of 0.25 to 0.3 mm. 
     In some embodiments, at least a portion of the second longitudinally resilient portion  44  and at least a portion of the remainder of the egg packaging, e.g. the cover portion  48  of the lid  3 , have the same thickness. 
     As with the first longitudinally resilient portion  32  provided by the base  8 , the second longitudinally resilient portion  44  of the lid  3 , is configured to flex such that, when a longitudinal force is applied to the portion  44 , for example by an egg  68  in the corresponding cavity  6 , the second longitudinally resilient portion  44  is moved in a direction away from the cavity  6 . In this way, the longitudinal force is absorbed by the second longitudinally resilient portion  44 . The arrangement of the concentric channel(s)  58  and corresponding ridge(s)  60  facilitates this flexing. When the second longitudinally resilient portion  44  is no longer subjected to a longitudinal force, the portion  44  springs back towards the cavity  6 , into its original position. 
     Accordingly, when the egg packaging  2  is subjected to a longitudinal force, an egg  68  in the cavity  6  may be forced against the lid  3  of the cavity  6 . In this way, the egg  68  applies a longitudinal force to the second longitudinally resilient portion  44  of the lid  3 . As described above, the second longitudinally resilient portion  44  is configured to flex such that, when the egg  68  applies a longitudinal force to the portion  44 , the longitudinally resilient portion  44  is moved in a direction away from the cavity. In this way, the longitudinal force is absorbed, at least partially, by the second longitudinally resilient portion  44 . 
     When the second longitudinally resilient portion  44  is no longer subjected to a longitudinal force, the portion  44  springs back towards the cavity  6 , into its original position. 
     In this way, eggs occupying the cavities  6  of the egg packaging  2  are supported against longitudinal movement relative to the longitudinal axis A in the direction of the base  8  of the cavity  6  and in the direction of the lid  3 . 
     Therefore the likelihood of breakage of the egg  68  from end-on impacts is reduced, since such forces are absorbed, at least partially, by the longitudinally resilient portions  32 ,  44  of the base and lid, by flexing of these portions. 
     Although the invention has been described above with reference to one or more embodiments, it will be appreciated that various changes or modifications may be made without departing from the scope of the invention as defined in the appended claims. For example, in alternative embodiments, it may be that a longitudinally resilient portion is provided only by the lid, in other words that there is no longitudinally resilient portion provided by the base. 
     With regards to the laterally resilient portion, it will be appreciated that other suitable profiles can also be used. For example, the laterally resilient portion  12  may comprise a flat profile  62 , as illustrated in  FIG. 14 , and not a curved profile  18  in a plane transverse to the longitudinal axis A. Flexing of the laterally resilient portion  12  is facilitated by the slit  30  provided adjacent the cavity opening  10 . It will be appreciated that the remaining features described in relation to the laterally resilient portions  12  of  FIGS. 1 to 6  also apply to the laterally resilient portion  12  illustrated in  FIG. 14 . 
     Alternatively, as shown in  FIG. 15 , the laterally resilient portion  12  may comprise a curved profile  18  in a plane transverse to the longitudinal axis A, wherein the curved profile  18  has a pair of apexes  18   a.  Each apex  18   a  is provided nearmost the longitudinal axis A. It will be appreciated that the remaining features described in relation to the laterally resilient portions  12  of  FIGS. 1 to 6  also apply to the laterally resilient portion  12  illustrated in  FIG. 15 . 
     Laterally resilient portions  12  as illustrated in  FIG. 15  are arranged to flex away from the cavity  6  in a similar manner to the laterally resilient portions  12  of  FIGS. 1-6 . In the case where there are four laterally resilient portions  12  per cavity  6 , this has the advantage that an egg in the cavity may be contacted by the laterally resilient portions  12  at up to eight contact points around the side of the egg i.e. at each apex  18   a.  Accordingly, any impact load on the side of the egg may be spread across up to eight contact points. 
       FIG. 16  illustrates a further alternative embodiment in which each laterally resilient portion  12  is formed as a resilient finger  64  extending from the side wall  16  of the cavity  6  in a direction away from the base  8  of the cavity  6 . Each resilient finger  64  comprises the same features as the laterally resilient portion  12  described in relation to  FIGS. 1-6 . In addition, each resilient finger  64  is defined by a slit  66  extending along either side of the finger  64  and across the top at a location adjacent the cavity opening  10 . In other words, the slit  66  is substantially u-shaped to define the finger  64 . The slit  66  is formed of two parallel slits  66   a  extending along the cavity side wall  16 , and a third slit  66   b  extending between the two parallel slits  66   a  at the cavity opening  10 . The third slit  66   b  being formed in the upper surface  70  of the body  4 . As can be seen from  FIG. 16 , each resilient finger  64  projects into the cavity  6  beyond the remainder of the cavity side wall  16 . 
     Each resilient finger  64  is configured to flex such that, when an egg applies a lateral force to the resilient finger  64 , the finger  64  is moved in a direction away from the cavity  6 , i.e. away from the longitudinal axis A. In this way, the lateral force is absorbed by the resilient finger  64 . When the resilient finger  64  is no longer subjected to a lateral force, the finger  64  springs back towards the cavity  6 , i.e. towards the longitudinal axis A, into its original position. 
     A further embodiment of the laterally resilient portions is illustrated in  FIGS. 17 and 18 . In this embodiment, each laterally resilient portion  12  is the same as those described in relation to  FIGS. 1 to 6 . In particular, the laterally resilient portions  12  include a curved profile  18  in a plane transverse to the longitudinal axis. The laterally resilient portions  12  also include an arcuate profile  24  which extends away from the base  8  of the cavity  6  such that a substantially ovoid cavity  6  is provided. 
     The laterally resilient portions  12  of the embodiment of  FIGS. 17 and 18  differ from those of  FIGS. 1 to 6  in that the arcuate profile  24  of each laterally resilient portion  12  does not extend the full height of the cavity  6 . The arcuate profile  24  extends part way along the height of the cavity  6 . As the laterally resilient portion  12  extends towards the open mouth of the cavity  6 , the arcuate profile  24 , which can be thought of as a concave profile, transitions into a convex curved profile  72  which extends away from the cavity  6 . The convex curved profile  72  terminates at the open end  8  of the cavity  6 , at which point the laterally resilient portion  12  is coupled to an upper surface  70  of the egg packaging body  4 . 
     Due to the curved profile  18  of the laterally resilient portion  12  in a plane transverse to the longitudinal axis A, and the curved profile  72  of the laterally resilient portion  12  in a plane along the longitudinal axis A, a convex portion  74  is formed which bulges or projects towards the longitudinal axis A. The convex portion  74  can be thought of as a domed portion, having its apex nearmost the longitudinal axis A. 
     The curvature of the convex portion  74  enables this portion to deflect away from the longitudinal axis A. Accordingly, when an egg is introduced into the cavity  6 , the convex portion  74  deflects away from the longitudinal axis A to accommodate the egg. The convex portion  74  is resilient such that, when the egg is removed from the cavity  6 , the convex portion  74  springs back to its original shape. In this way, absorption of lateral forces impacting on the egg is facilitated. 
     The convex portion  74  is arranged to abut a surface of an egg in the cavity  6 . In this way, retention of the egg in the cavity  6  is facilitated since the convex portions  74  provide a “gripping” action against the surface of the egg. 
     It is noted that no slits or openings in the cavity side wall  16  and/or the body upper wall  70  are required to enable deflection of the convex portion  74  or the laterally resilient portion  12  in general. 
     The convex portion  74  also comprises a reduced thickness in relation to the remainder of the packaging, as is the case with the laterally resilient portion  12  in general, which is described in detail above. For example, the thickness of the convex portion  74  is in the range of 0.2 mm to 1.0 mm, for example in the range of 0.2 mm to 0.7 mm, for example in the range of 0.2 mm to 0.5 mm, for example in the range of 0.25 to 0.4 mm, for example in the range of 0.25 to 0.3 mm. 
     In some embodiments, the convex portion  74  and at least a portion of the remainder of the egg packaging, e.g. the side wall  16 , have the same thickness.
