  • The present invention relates to a fibre moulded package for accommodating foodstuffs such as eggs which package comprises;
    • a base part comprising a plurality of accommodations for receiving an egg,
    • a cover part coupled with the base part and hingeable relative to the base part between a closed position and an open position, wherein the cover part comprises a window section for providing a view to the interior of the package from the outside,
    • locking members for holding the cover part in its closed position.
  • Such a package is known from EP1683740A1 which relates generally to packages for fragile products, such as eggs, where the package is made of an opaque material such as moulded pulp and particularly to such packages provided with means allowing visual inspection of the contents of the package. The package is thus provided with a window portion located centrally in the top surface of the cover part, where the window portion comprises a number of apertures through the top surface located and dimensioned to provide for visual inspection of each of the eggs in the package. These apertures extend into the window portion itself but may also extend into a vertical rim portion surrounding the window portion. The window portion can be provided with laterally extending brace members in order to increase the strength and rigidity of the window potion. However, in circumstances, the strength and rigidity of the cover port having a window portion does not suffice because of the window portion which potentially weakens the cover part. This weakened cover part then may also cause closure problems.
  • The present invention relates in particular to relative big package like the 3x6 egg carton shown in US 4,492,331 or 15-cell packages. For these type of relative big packages, in circumstances, the strength and rigidity of the cover port having a window portion does all the more not suffice because of the window portion.
  • US 3 362 605 A relates to a packaging container including a cellular tray and a cover cooperating therewith. The cellular tray has a plurality of hollow posts integral with hollow partitions and an outer wall defining compartments or cells surrounding the posts. The cover will cooperate with the tray and includes means whereby the cover may be dis placed to permit ready access to the tray contents.
  • Summary of the invention
  • The invention aims to provide a fibre moulded package for accommodating foodstuffs such as eggs, wherein the foodstuff is visible but still the package meets severe demands with respect to strength and vibration resistance.

    Detailed description of embodiments
  • In the figures 1-7 an embodiment of the fibre moulded package according to the invention which is now described in more detail referring to figures 1-6.
  • A fibre moulded package 1 is shown which package 1 is suitable for accommodating foodstuffs such as eggs. The package 1 comprises a base part 2 and a cover part 4. The cover part 4 is coupled with the base part by a hinge 19 which is a resilient hinge formed with the package 1 in a usual manner. The cover part 4 is hingeable around the hinge 19 relative to the base part 2 between a closed position shown in fig. 1 and an open position shown in fig. 4.
  • The base part 2 comprises a plurality of accommodations 3 for receiving an egg. These accommodations 3 are arranged and formed in a usual manner in rows separated by posts 20 which extend from the base part 2 towards the cover part 4 in closed position. These posts 20 support the cover part 4 such that stacking of packages 1 is allowed.
  • The cover part 4 comprises a a window section 5 for providing a view to the interior of the package 1 from the outside. The cover part 4 has a cover part top surface 8 which is generally flat for enabling printing onto the cover part top surface 8. The cover part 4 has a circumferential side wall 15 which extend in closed position from the cover part top surface 8 towards the base part 2. The side wall 15 comprises a number of printable sections 21 such that the side wall 15 is substantially planar for enabling printing onto the side wall 15. This desire for printing area on both the cover part top surface 8 and the side wall 15 compromises the strength of the package 1, specifically the cover part 4 thereof. The side wall 15 at the hinge 19 is provided with a number of indentations 23 for strengthening the side wall 15. It will be clear that although not shown in the figures, similar indentations may be provided in other side walls of the cover part 4 as well.
  • The package 1 comprises locking members 6, 7, 22 arranged in a usual manner opposite the hinge 19 for holding the cover part 4 in its closed position. The locking means have cooperating cams 7 and recesses 6. The cams 7 are provided with a locking flap 22 which is hingeably with the base part 2. The recesses 6 are provided with the cover part 4.
  • At the corners of the cover part 4, curved sections 28 are provided between the cover part top surface 8 and a bulge 27 which bulge couples two sidewalls at the corner. The curved section 28 bridges the entire corner between two coupled side walls and beneficially provides additional strength to the cover part 4.
  • The window section 5 is arranged with the cover part 4 for providing view on the packaged eggs. The window section 5 extends along almost the entire length of the cover part 4. The window section 5 is arranged with the cover part top surface 8 in such a manner that essentially an entire row of the plurality of accommodations 3 for receiving an egg is visible from the exterior of the package 1. The window section 5 is arranged with the cover part 4 in an asymmetric manner which is beneficial in view of available printing area and strength of the cover part 4. The window section 5 is arranged offset the centre of the package 1, which means offset the longitudinal axis of the package 1. Therefore, here, all of the number of window openings 12 are oriented towards the centre of the package 1.
  • The window section 5 is shaped such that it is basically triangular in cross section as shown in fig. 6. The window section 5 has a window plane 9 wherein all of the window openings 12 extend. Therefore, the window plane 9 is regarded a single window plane 9. The window plane 9 extends from about the centre of the cover part 4 towards the locking members 6, 7, 22 at a slight angle α with respect to the cover part top surface 8 for providing resistant strength to the cover part 4. The window plane 9 forms one side of the basically triangular shape of the window section 5.
  • The window section 5 comprises a circumferential wall 31-34 which contributes in the strength of the window section 5 and the cover part 4. The circumferential wall 31-34 extends from the cover part top surface 8 towards the window plane 9 and joins the window plane 9 such that the basically triangular shape is formed.
  • The window plane 9 here makes an angle α of about 30° which is an example of a slight angle and therefore the shallow window section5 does not deeply extend into the interior of the package 1.
  • The window section 5 comprises a number of window frame members 10. These number of window frame members 10 delimit a number of window openings 12. Each window frame member 10 is provided with a stop surface 11 for engaging the base part 2 when the cover part 4 is in its closed position. Each respective window frame member 10 has a relative high and small window frame member portion 25 which is best seen in fig. 1 from the exterior of the package 1. The stop surface 11 is beneficially arranged opposite the relative high and small window frame member portion 25 such that upon forming the portion 25, fibre material accumulates and provides a massive portion for constituting the stop surface 11.
  • Here, each window frame member 10 comprises two rims 13, 14 adjacent the stop surface 11 for facilitating secure engaging of the stop surface 11 and the base part 2 when the cover part 4 is in its closed position. This secure engagement is caused by the form closed engagement of a post 20a with the stop surface 11. The post 20a is kept in position on the stop surface 11 by the rims 13, 14 which mutually enclose an angle. The post 20a is therefore slightly shortened in length without losing its function in forming the accommodations 3.
  • The window section 5 is arranged with the cover part top surface 8 at a position such that the number of stop surfaces 11 are proximate the locking members 6, 7, 22. This is beneficial in terms of secure locking of the package 1 in its closed positions because mutual twisting of the cover part 4 and the base part 2 is reduced. Each respective window frame member 10 has a plate portion 26 which extends mainly in the window plane 9 and adds to the strength of the cover part 4.
  • The window section 5 has a circumferential side wall 31-34 which extends continuously around the entire window section 5 for providing strength to the cover part 5.
  • Thus the shown window section 5 ensures; sufficient printing area being left, a proper view on the packaged eggs, a cover part 4 with an adequate strength, and an improved closure of the package 1 because of the robust engagement of the posts 20a with the stops surfaces 11 of the stiff window section 5.
  • The window section 5 is configured such that automated or manual denesting is facilitated of a stack of packages 1 in the open position. This configuration involves the window frame portion 25 having a window stile 29. This window stile 29 has a narrow and high shape as can be seen in fig. 7. The narrow window stile 29 has a triangular shape with a ratio of between base b and height h such that during manufacture of the package the section of the mould forming window stile 29 is sucked full with pulp and thus forms a substantially solid window stile 29 having a core 30 made of pulp. This solid window stile 29 all the more provides strength to the cover part 4. In addition, this solid window stile 29 is beneficial in denesting a stack of fold open packages because adjacent stiles of adjacent packages abut and prevent mutual clamping of in particular the cover part 4 which is important because a generally flat cover part 4 is prone to such clamping. The moulding process for a fibre moulded package is known per se. The moulding dies of the machine are dipped into the pulp and a vacuum is applied to the die and in that way a product is created. The wet product is placed on a conveyor belt and sent through a drying tunnel. Finally, the dried products may be pressed, counted, bundled, printed, labelled, palletised and despatched to the end user. Reference is for example made to US 3.320. 120 and US 3.654. 076 .
  • The side wall 15 of the cover part 4 is provided with a circumferential cover rim 16 at the end of the side wall 15 away from the cover part top surface 8. This rim 16 provides a rim surface 18 for abutting the base part 2 when the cover part 4 is in its closed position. The side wall 15 is provide with a bulge 17 which extends inward the interior of the package 1 for increasing the rim surface 18 at the bulge 17.
  • It will also be obvious after the above description and drawings are included to illustrate some embodiments of the invention, and not to limit the scope of protection. Starting from this disclosure, many more embodiments will be evident to a skilled person which are within the scope of protection and the essence of this invention and which are obvious combinations of prior art techniques and the disclosure of this patent.
