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 30mm or less, for example in the range of

10mm-20mm, for example less than 10mm, for example less than 5mm, e.g. 2-3mm. 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 0-20mm, for example 0-lOmm.

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 0-20mm, for example 0-lOmm.

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-mache, 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 0.2mm to 1mm, for example in the range of 0.2mm to 0.7mm, for example in the range of O.mm to 0.5mm, for example in the range of 0.25 to 0.4mm, for example in the range of 0.25 to 0.3mm.

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 0.2mm to 1.0mm, for example in the range of 0.2mm to 0.7mm, for example in the range of 0.2mm to 0.5mm, for example in the range of 0.25mm to 0.4mm, for example in the range of 0.25mm to 0.3mm. 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 Figure 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 Figure 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 Figures 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 Figures 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 Figure 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 Figures 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 18a 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 18a is provided closer to the longitudinal axis A than the remainder of the curved profile 18. As can be seen in Figures 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 Figure 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 Figures 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 10mm-20mm. 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 0-20mm, for example 0-lOmm.

With reference to Figure 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 24a 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 24a 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 Figure 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 Figures 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 Figures 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 24a 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 24a 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 24a 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 24a 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 24a 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 Figures 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 Figure 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-mache, or any other suitable material. The thickness of the plastics material from which the egg packaging is formed is typically in the range of 0.4-1.0mm, for example 0.4-0.7mm, for example 0.4-0.5mm.

Accordingly, the side wall 16 of the respective cavities has a thickness in the range of 0.4-1.0mm, for example 0.4-0.7mm, for example 0.4-0.5mm.

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 0.2mm to 1.0mm, for example in the range of 0.2mm to 0.7mm, for example in the range of 0.2mm to 0.5mm, for example in the range of 0.25 to 0.4mm, for example in the range of 0.25 to 0.3mm.

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 Figure 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.

Figure 7 shows a first embodiment of the longitudinal resilient portion 32 comprising a single channel 38 and corresponding ridge 40. Figure 8 shows a second embodiment of the longitudinally resilient portion 32, which also comprises a single channel 38 and corresponding ridge 40. Figure 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 Figures 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 Figures 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 0.2mm to 1.0mm, for example in the range of 0.2mm to 0.7mm, for example in the range of 0.2mm to 0.5mm, for example in the range of 0.25 to 0.4mm, for example in the range of 0.25 to 0.3mm.

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 Figures 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 Figure 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 Figure 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 Figure 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.

Figure 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 Figure 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 Figure 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 Figures 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 0.2mm to 1.0mm, for example in the range of 0.2mm to 0.7mm, for example in the range of 0.2mm to 0.5mm, for example in the range of 0.25 to 0.4mm, for example in the range of 0.25 to 0.3mm.

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 Figure 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 Figures 1 to 6 also apply to the laterally resilient portion 12 illustrated in Figure 14.

Alternatively, as shown in Figure 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 18a. Each apex 18a 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 Figures 1 to 6 also apply to the laterally resilient portion 12 illustrated in Figure 15.

Laterally resilient portions 12 as illustrated in Figure 15 are arranged to flex away from the cavity 6 in a similar manner to the laterally resilient portions 12 of Figures 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 18a.

Accordingly, any impact load on the side of the egg may be spread across up to eight contact points. Figure 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 Figures 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 66a extending along the cavity side wall 16, and a third slit 66b extending between the two parallel slits 66a at the cavity opening 10. The third slit 66b being formed in the upper surface 70 of the body 4. As can be seen from Figure 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 Figures 17 and 18. In this embodiment, each laterally resilient portion 12 is the same as those described in relation to Figures 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 Figures 17 and 18 differ from those of Figures 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 0.2mm to 1.0mm, for example in the range of 0.2mm to 0.7mm, for example in the range of 0.2mm to 0.5mm, for example in the range of 0.25 to 0.4mm, for example in the range of 0.25 to 0.3mm.

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.
