Description

TECHNICAL FIELD

[0001] The present invention pertains to a display and distribution package for eggs.

BACKGROUND OF THE INVENTION

[0002] Packages for packing and transporting eggs are known in a variety of forms. Traditionally, such packages have comprised a bottom part provided with suitably shaped compartments for accommodation of the eggs, and an upper part forming a cover over the bottom part for accommodating the upper portions of the eggs housed within the package and for closing the package. Often, the upper part is connected to the lower part by means of a suitable hinge portion, although packages comprising separate bottom and upper parts have also been used. In those packages that comprise a hingedly connected bottom and cover part, the vertical front side of the bottom part is often provided with a flexible flap comprising a number of protrusions for engagement with correspondingly located and shaped holes in the cover part, thereby locking the bottom and cover parts together in the closed state of the package. A package of this kind suffers from various disadvantages. In the closed position, the front face of the package will be subdivided into an upper part and a lower part and as the lower part is typically formed to be able to accommodate and support the articles contained within the package, it is only the upper part which can be given a planar shape that permits the application of text and pictures describing the contents of the package. In use in a store, such packages will often be stacked in a sales rack, and hence it is only the vertical front side, which is visible to the customer.

[0003] EP 1 373 100 discloses a display and distribution packaging unit for fragile articles, especially for eggs, comprising a bottom part which at least partially matches the outer contours of the eggs housed within the unit and a cover part comprising planar top-and side surfaces for the provision of graphical information about the contents of the unit, where portions of the end surfaces of the cover part are shaped to reflect the shape of the eggs housed within the display and distribution package. A problem with this egg package is that the closing and locking mechanism is provided by a traditional locking flap having a protrusion, which extends through an aperture in the front side of the cover part, thus, reducing the available place for a label.

[0004] Thus, in the prior art egg packages it has only been possible to place a label on the top surface of the cover part, which often is not visible, when the egg packages are stacked in a sales rack. There has thus always been a conflict between having a large surface for the placement of a label and at the same time having a reliable closing and locking mechanism, i.e. a large area for a label without compromising the reliability of the locking mechanism. Additionally, a closure flap as known from EP 1 373 100 is an element that increases the cost of manufacture and transport of the egg packages.

SUMMARY OF THE INVENTION

[0005] It is thus an object of the present invention to provide an egg package, which due to its form provides a clear, visible information about the contents of the unit and at the same time offers good opportunities for providing graphical and/or pictorial information on large surfaces of the unit.

[0006] It is a further object of the present invention to provide an egg package, which may be reliably closed and locked in a substantially error free manner by a machine.

[0007] It is a further object of the invention to provide a packaging unit which can be produced as one integrated unit for instance by suction moulding.

[0008] According to the present invention, the above-mentioned and other objects are fulfilled by an egg package formed of a fibrous material, the egg package comprising the following main parts:

• a bottom part comprising a plurality of egg-receiving compartments having non-planar side surfaces so as to match at least partially the outer contours of an egg, the plurality of compartments being arranged in at least two parallel rows,
• a cover part comprising a top surface, a front surface, a back surface, and two substantially planar end surfaces,
• the cover part being permanently connected to the bottom part by a hinge between the back surface of the cover part and the bottom part so as to allow the cover part to move between an open position and a closed position,
• said cover part comprising partial ovoid portions extending outwardly from the two substantially planar end surfaces, wherein each of the two substantially planar end surfaces apart from the ovoid portions completely spans the entire end surfaces of the cover part,
• the bottom part comprising a back side, a front side, two end sides, and at least one upwardly extending retainment projection extending from the front side of the bottom part, the upwardly extending retainment projection having a downwardly and outwardly extending retainment flap for locking engagement with one or more co-operating apertures in the front surface of the cover part,
• the retainment flap not extending beyond the front surface of the cover part when the cover part is in its closed position,
• the cover part being provided with a label covering the top surface and a substantial part of the front surface of the cover part.

[0009] The packaging unit according to the present invention thus comprises a bottom part provided with one or more compartments for accommodating and supporting the eggs in the packaging unit and a cover part, where one or more portions of the cover part are shaped such that they reflect the shape of the eggs contained within the packaging unit, thereby making the shape of the eggs contained within the unit visible from outside. By shaping portions of the cover part in this manner the contents of the packaging unit becomes more apparent than in prior art packaging units, not only when the packaging unit is seen from the side - where both the bottom part and the cover part can be seen - but also when seen from above, in which case the bottom part may be more or less invisible to the viewer.

[0010] According to the invention, said cover part and said bottom part can be moulded as one integrated unit by suction moulding.

[0011] It should be noted that throughout this description and the appended claims the expression: partial ovoid portions should be understood as a portion having a shape that provides a viewer with a clear association of the form of an egg without necessarily having a form exactly corresponding to an egg. Thus, surfaces or sub-surfaces of a number of different solids of revolution, for instance of an ellipsoid, may reflect the shape of an egg within this context.

[0012] Moreover, a reliable and stable locking function that may be facilitated by simple mechanical closing means is achieved, for example provided by packing machinery without the risk of damaging the fragile eggs that are placed in the package. This is due to the fact that the egg package according to the above embodiment may be closed and locked in one operation by pivoting the cover part in relation to the hinge. This pivoting of the cover part may thus be facilitated by only one mechanical operation by the packing machinery. Typically, packaging machinery is adapted for handling a tremendous number of packages over a short time span. It is therefore an important advantage of the present embodiment that the package can be closed and locked in an error free and reliable manner by the packaging machinery. Since, the retainment flap(s) are projecting downwardly and outwardly, the cooperating aperture(s) on the cover part can slide over the retainment flap(s) during closing of the egg package and engage it in a locking manner, because the retainment flap(s) will simply work as a hook that hooks onto a lower edge of the aperture. This way a simple ― yet effective way ― of providing reliable locking means on the cover part is achieved, which furthermore is easy to manufacture. Preferably, there is a number of such apertures that corresponds to the number of retainment flaps.

[0013] Since, the retainment flaps do not extend beyond the front surface of the cover part when the cover part is in its closed position, it is possible to equip the cover part with a label covering the top surface and the entire front surface of the cover part.

[0014] Accordingly, it is seen that the claimed locking mechanism and the ovoid portions of the end surfaces provides the synergetic effect by which all technical locking features are hidden beneath the label, thus providing an egg package, which due to its form provides a clear, visible information about the contents of the unit and at the same time offers good opportunities for providing graphical and/or pictorial information on remaining surfaces of the cover part.

[0015] Additionally consumer investigations have shown that a label does not provide enough sales appeal. However, if in addition to labels the egg package is distinguished by its form as well it provides a greater appeal to towards the consumer. Egg packages have more or less looked the same during the last decades. Thus, by the provision of an egg package of the kind as described above, wherein a label is placed over the top surface of the cover part and a substantial part of the front surface of the cover part, and which is provided with the ovoid portions on the end surfaces of the cover part a very consumer appealing egg package is provided, because there are no disrupting features (e.g. the locking mechanism), which may interfere with the impression the package will give the consumer. This simplicity and "cleanness" of the egg package will furthermore make it more easily recognizable for a consumer.

[0016] According to an embodiment the label covers substantially the entire front surface of the cover part.

[0017] According to a preferred embodiment, the one or more apertures are formed in one or more recesses in the front surface of the cover part. Hereby is achieved a safer locking mechanism because a larger retainment flap may be used, which at the same time does not extend through the front surface of the cover part.

[0018] According to an embodiment, the one or more recess in the front surface of the cover part extends from the upper part of the front surface of the cover part, adjacent to the top surface of the cover part, and down to approximately the middle of the front surface of the cover part. Hereby is achieved an enhanced reliability of the locking mechanism, because recesses placed in this way will provide an anti-bowing effect on the front surface of the cover part in a direction along the longitudinal extension of the recesses.

[0019] Preferably, the recesses comprise a bottom wall and two opposing sidewalls extending from the front surface of the cover part to the bottom wall.

[0020] According to a preferred embodiment, the cover part comprises a tongue that extends upwardly and inwardly from the lower edge of the one or more apertures, said lower edge of the one or more apertures being substantially flush with the front surface of the cover part, said tongue being adapted for cooperating with the outwardly and downwardly extending retainment flap. Hereby is achieved a simple ― yet effective ― locking mechanism, wherein the egg package can be closed and locked by a single mechanical operation of a packaging machinery, because when the package is being closed the inwardly and upwardly extending tongue will slide over the outwardly and downwardly extending retainment flap. During this sliding the retainment flap and tongue will bend slightly, and then relax back to the normal position when they slide pass each other - due to the slight resilience of the fibrous material.

[0021] According to a preferred embodiment, the partial ovoid portions in the cover part are about one quarter of a complete ovoid. This gives a distinct and clear information to a consumer that this particular package contain eggs.

[0022] In a preferred embodiment, the partial ovoid portions of the cover part continue in the corresponding egg-receiving compartments in the bottom part, the corresponding portions in the cover part and in the bottom part thereby matching a continuous portion of a surface of an egg. Providing not only the cover part with portions reflecting the shape of the eggs in the unit but also shaping the corresponding portions of the bottom part such that they reflect the shape of the eggs further enhances the visual information about the content of the unit. The individual portions of the cover part and the corresponding portions of the bottom part may in the closed state of the unit merge into a substantially continuous surface reflecting a relatively large portion of the surface of an egg.

[0023] According to an embodiment, the partial ovoid portions located at the end surfaces of the cover part together with the corresponding egg-receiving compartments in the bottom part constitutes not less than approximately 60% of the total surface of an egg. Hereby, the eggs are supported in a manner which reduces the risk of damages of the eggs caused by the accelerations experienced for instance during vibrations of the unit and if the unit is accidentally dropped. Specifically said compartments can also be formed to support the eggs at the bottom portion of the compartments.

[0024] Preferably, the surface structure of the partial ovoid portions has a different surface structure than the remaining portions of the cover part. By providing those portions of the cover part, which reflect the content of the unit, with a surface structure differing from the surface structure of the remaining portions of the cover part, the content of the packaging unit is made even more apparent as seen from outside, for instance for a customer in a store.

[0025] For example the surface structure of the partial ovoid portions is relatively smooth, while the surface structure of the remaining surfaces of the package are relatively coarse, or alternatively the surface structure of the partial ovoid portions is relatively coarse, while the surface structure of the remaining surfaces of the package are relatively smooth.

[0026] In a preferred embodiment, the interface between the cover part and bottom part inclines downwardly from the rear side of the package to the front side, thus yielding a higher front surface of the cover part than back surface of the cover part, thus yielding a higher front side of the cover part than rear side of the cover part, the higher front side thereby providing more space for the attachment of labels, etc. On opening the cover part of the filled packaging unit a larger part of the eggs contained in the unit thus becomes visible from the front side of the unit, which is normally the side of the unit facing the customer in a store. This provides for a better opportunity to inspect the eggs in the unit, for instance for possible damages hereof and has the further effect that the eggs in the unit appear larger. The interface between the cover part and bottom part is preferably curved.

[0027] The lower edge of the front surface of the cover part is preferably curved in a downward direction beneath an interface between the cover part and bottom part for extension of the area of the front surface and for facilitating opening of the unit. This is done in order to provide a better grip of the edge portion of the cover part for opening the unit - and also in order to further increase the area of the front surface of the cover part and hence the possibility to attach labels etc. to this portion of the cover part. For example, the lower edge of the front surface may according to the invention be extended in a downwards direction past the interface between the cover part and the bottom part. The downward extension of the front surface of the cover part may cover up to the total height of the bottom part.

[0028] In order to enhance the locking engagement between the retainment flaps and the corresponding cooperating apertures in the cover part, the egg package may according to a preferred embodiment be so constructed that the lower part of the front surface of the cover part bulges inwardly. Such an inwardly bulging lower part of the front surface of the cover part will ― due to the slight resilience of the pulp material ― slide over the upwardly extending retainment projections which will force the front surface to bulge outwardly in such a manner that it will slide over these projections in an abutting manner until the apertures in the cover part will slide over the retainment flaps, and therefore provide a more reliable locking engagement between the cover part and the bottom part.

[0029] In a preferred embodiment the cover part may comprise a rim portion extending outwardly from the cover part. This rim portion may function as a gripping area for automated de-nesting machinery that is used in most egg packaging facilities.

[0030] In most countries there is a legal requirement that egg packages are provided with technical information about the eggs, such as farming conditions, origin, nutritional information, etc. Thus, according to a preferred embodiment the inner side of the top surface of the cover part comprises a substantially flat, and preferably also rectangular, info area onto which technical detail about the eggs is provided. Hereby it is achieved that such technical information is not directly visible from outside a closed egg package, and that such information therefore cannot interfere with the label and brand that the producer wants to convey to the consumer.

[0031] According to a preferred embodiment the egg package is formed by suction moulding of a fibrous material, such as moulded pulp.

[0032] Advantageously, the bottom part may comprise a rim portion extending outward from the bottom part.

[0033] The cover of an egg package of the above mentioned kind, i.e. one that is made of a fibrous material, is usually too soft to support layers of additional egg packages, filled with eggs, on top of each other, for example in a sales rack. Without at least one upwardly extending projection located between the rows of egg receiving compartments to support the cover when the egg package is closed, the weight of the additional egg filled egg packages will rest on the eggs of the lower packages in the stack, which then may break during storage and transport. Thus, according a preferred embodiment of the invention the inner side of the top surface of the cover part rests on the top of said upwardly extending projections of the bottom part when the cover part is in the closed position.

DETAILED DESCRIPTION

[0035] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. The invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numerals refer to like elements throughout. Like elements will, thus, not be described in detail with respect to the description of each figure.

[0036] Fig. 1-4 shows an embodiment of a display and distribution package 2 for eggs according to the invention as seen from different perspectives. The package 2 is formed of a fibrous and opaque material. The illustrated package 2 is shown in its closed position, and it comprises a bottom part 4 comprising a plurality of egg-receiving compartments 8 having non-planar side surfaces so as to match at least partially the outer contours of an egg, the plurality of compartments 8 are arranged in two parallel rows.

[0037] As can be seen more clearly in Fig. 3 the cover part 6 comprising a top surface 10, a front surface 12, a back surface 14. The cover part 6 is permanently connected to the bottom part 4 by a hinge 16 between the back surface 14 of the cover part 6 and the bottom part 4 so as to allow the cover part 6 to move between an open position and a closed position.

[0038] As can be seen more clearly in Fig. 2 and Fig. 4, the cover part also comprises two substantially planar end surfaces 18. Referring now to Fig. 1-4, it is seen that the cover part 6 comprises furthermore partial ovoid portions 20 extending outwardly from the two substantially planar end surfaces 18, wherein each of the two substantially planar end surfaces 18 apart from the ovoid portions 20 completely spans the entire end surfaces of the cover part 6.

[0039] Fig. 5 shows the same embodiment of an egg package as shown in Fig. 1-4, but here in an end-view and in the open position. In Fig. 5 it is shown that the bottom part 4 comprises a back side 22, and a front side 24 (and two end sides, which are not illustrated). Also shown in Fig. 5 is an upwardly extending retainment projection 26 extending from the front side 24 of the bottom part 4. The upwardly extending retainment projection 26 has a downwardly and outwardly extending retainment flap 28 for locking engagement with one or more co-operating apertures 30 in the front surface 12 of the cover part 6 (see for example Fig. 1 for a better view of the apertures). The retainment flap 28 is configured for not extending beyond the front surface 12 of the cover part 6 when the cover part 6 is in its closed position,

[0040] As illustrated in Fig. 1, the apertures 30 are formed in corresponding recesses 32 in the front surface 12 of the cover part 6. Hereby is achieved a safer locking mechanism because a larger retainment flap 28 may be used, which at the same time does not extend through the front surface 12 of the cover part 6.

[0041] As can be clearly seen in Fig. 1 and Fig. 2, the recess 32 in the front surface 12 of the cover part 6 extends from the upper part of the front surface 12 of the cover part 6, adjacent to the top surface 10 of the cover part 6, and down to approximately the middle of the front surface 12 of the cover part 6. Hereby is achieved an enhanced reliability of the locking mechanism, because recesses 32 placed in this way will provide an anti-bowing effect on the front surface 12 of the cover part 6 in a direction along the longitudinal extension of the recesses 32.

[0042] The recesses 32 comprises a bottom wall 34 and two opposing sidewalls 36 extending from the front surface 12 of the cover part to the bottom wall 34 (these features are only marked in one of the recesses 32 in Fig. 1, in order to increase the intelligibility of the Figures).

[0043] Fig. 6A shows a cross section of the egg package 2 illustrated in Fig. 1-5. The cover part 6 of an egg package 2 of the above mentioned kind, i.e. one that is made of a fibrous material, is usually too soft to support layers of additional egg packages 2, filled with eggs, on top of each other, for example in a sales rack. Without at least one upwardly extending projection 38 located between the rows of egg receiving compartments 8 to support the cover part 6 when the egg package is closed, the weight of the additional egg filled egg packages will rest on the eggs of the lower packages in the stack, which then may break during storage and transport. Thus, according a preferred embodiment, the inner side of the top surface 10 of the cover part 6 rests on the top of said upwardly extending projections 38 of the bottom part 4, when the cover part 6 is in the closed position.

[0044] In the close-up Fig. 6B is illustrated a cover part 6, which comprises a tongue 40 that extends upwardly and inwardly from the lower edge of the one or more apertures 30, said lower edge of the one or more apertures being substantially flush with the front surface 10 of the cover part 6, said tongue 40 being adapted for cooperating with the outwardly and downwardly extending retainment flap 28. Hereby is achieved a simple ― yet effective ― locking mechanism, wherein the egg package 2 can be closed and locked by a single mechanical operation of a packaging machinery, because when the package 2 is being closed the inwardly and upwardly extending tongue 40 will slide over the outwardly and downwardly extending retainment flap 28. During this sliding the retainment flap 28 and tongue 40 will bend slightly, and then relax back to the normal position when they slide pass each other - due to the slight resilience of the fibrous material. The illustrated part of the front surface 12 of the cover part 6 is equipped with a label 42 covering all the locking mechanism of the egg package 2. When a user needs to open the package 2 he/she only needs to pull outwardly in the lower edge 46 of the front surface 12.

[0045] Fig. 7 shows a perspective view of the egg package 2, wherein the cover part 6 is provided with a label 42 covering the top surface 10 and the entire front surface 12 of the cover part 6, whereby all the technical features of the locking mechanism are hidden by the label. Thus, giving a clean and smooth appearance. The partial ovoid portions 20 in the cover part 6 are about one quarter of a complete ovoid. This gives distinct and clear information to a consumer that this particular package 2 contains eggs.

[0046] As illustrated, the partial ovoid portions 20 of the cover part 6 continue in the corresponding egg-receiving compartments 8 in the bottom part 4, the corresponding ovoid portions 20 in the cover part 6 and in the bottom part 4 thereby matching a continuous portion of a surface of an egg. Providing not only the cover part 6 with portions reflecting the shape of the eggs in the unit but also shaping the corresponding portions 8 of the bottom part 4 such that they reflect the shape of the eggs further enhances the visual information about the content of the unit. The individual ovoid portions 20 of the cover part 6 and the corresponding portions 8 of the bottom part 4 may in the closed state of the unit merge into a substantially continuous surface reflecting a relatively large portion of the surface of an egg.

[0047] Preferably, the partial ovoid portions 20 located at the end surfaces 10 of the cover part 6 together with the corresponding egg-receiving compartments 8 in the bottom part 5 constitutes not less than approximately 60% of the total surface of an egg. Hereby, the eggs are supported in a manner which reduces the risk of damages of the eggs caused by the accelerations experienced for instance during vibrations of the package 2 and if the package 2 is accidentally dropped. Specifically said compartments 8 can also be formed to support the eggs at the bottom portion of the compartments 8.

[0048] Preferably, the surface structure of the partial ovoid portions 20 has a different surface structure than the remaining portions of the cover part 6. By providing those portions of the cover part 6, which reflect the content of the package 2, with a surface structure differing from the surface structure of the remaining portions of the cover part 6, the content of the package 2 is made even more apparent as seen from outside, for instance for a customer in a store.

[0049] For example the surface structure of the partial ovoid portions 20 is relatively smooth, while the surface structure of the remaining surfaces of the package 2 are relatively coarse, or alternatively the surface structure of the partial ovoid portions 20 is relatively coarse, while the surface structure of the remaining surfaces of the package 2 are relatively smooth.

[0050] As illustrated in Fig. 7, and more clearly in Fig. 3, the interface 44 between the cover part 6 and bottom part 4 inclines downwardly from the rear side of the package 2 to the front side, thus yielding a higher front surface 12 of the cover part 6 than back surface 14 of the cover part 6, the higher front surface 12 thereby providing more space for the attachment of labels 42, etc. On opening the cover part 6 of the filled package 2 a larger part of the eggs contained in the unit thus becomes visible from the front side of the package 2, which is normally the side of the package facing the customer in a store. This provides for a better opportunity to inspect the eggs in the unit, for instance for possible damages hereof and has the further effect that the eggs in the package 2 appear larger. The interface between the cover part 6 and bottom part 4 is preferably curved.

[0051] The lower edge 46 of the front surface of the cover part is preferably curved in a downward direction beneath an interface 44 between the cover part 6 and bottom part 4 for extension of the area of the front surface 12 and for facilitating opening of the unit. This is done in order to provide a better grip of the edge portion 46 of the cover part 6 for opening the package 2 - and also in order to further increase the area of the front surface 12 of the cover part 6 and hence the possibility to attach labels 42 etc. to this portion of the cover part 6. For example, the lower edge 46 of the front surface 6 may according to the invention be extended in a downwards direction past the interface 44 between the cover part 6 and the bottom part 4. The downward extension of the front surface 12 of the cover part 6 may cover up to the total height of the bottom part 4.

[0052] In order to enhance the locking engagement between the retainment flaps 28 and the corresponding cooperating apertures 30 in the cover part, the egg package 2 may according to a preferred embodiment be so constructed that the lower part 46 of the front surface 12 of the cover part 6 bulges slightly inwardly. Such an inwardly bulging lower part 46 of the front surface 12 of the cover part 6 will ― due to the slight resilience of the pulp material ― slide over the upwardly extending retainment projections 26 which will force the front surface 12 to bulge outwardly in such a manner that it will slide over these projections 26 in an abutting manner until the apertures in the cover part will slide over the retainment flaps 28, and therefore provide a more reliable locking engagement between the cover part 6 and the bottom part 4.

[0053] The egg package 2 is preferably formed by suction moulding of the fibrous material, which preferably is pulp.
