Definitions

  • This invention relates to packaging containers for eggs, fruit or other articles.
  • an egg box comprising a base portion formed of plastics material having egg receiving depressions and a height which is greater than that of the eggs, and a flat cardboard lid supported on pillars within the base portion. The lid is clipped to the pillars to hold it in place after the box has been filled with eggs.
  • the lid retaining means are tags in the lid which are depressed through holes in the upper surfaces of the pillars, each tag having a lip which engages beneath the upper surface of the respective pillar.
  • the lid may be removed by pulling the tags from within the pillars. However, such action tends to destroy the tag sufficiently to prevent the lid being reclosable.
  • a packaging container comprising a base portion formed of plastics material having a surrounding wall, a separate lid, and retaining means for holding the lid on the base portion, the retaining means comprising at least one projection moulded integrally with the base portion, the or each projection being of hook-like configuration having a stem merging into a lug extending substantially perpendicularly thereto for interengagement with the lid.
  • the or each projection is preferably moulded with an upright hollow stem and a hollow lug.
  • the lug of the or each projection in use, overlies the outer, e.g. the upper, surface of the lid.
  • the container is a deep-walled cmtainer, in which the surrounding wall of the base portion has a height which is greater than the article or articles to be packaged, and the lid is a substantially flat lid.
  • the base portion has at least one pair of lid supporting pillars, and the retaining means comprise one said projection upstanding from each pillar and aligned apertures in the lid through which the lug of each projection may pass.
  • each aperture is D-shaped or crescent shaped.
  • the lugs of the projections of the or each pair of pillars face in opposite directions, preferably away from each other.
  • the or each projection of the retaining means is incorporated into the surrounding wall of the base portion.
  • the container may be generally rectangular and have a projection provided at each corner of the base portion, the lug of each projection extending inwardly.
  • the or each projection may be provided in combination with means for strengthening the surrounding wall and/or a ledge beneath the lug of the or each projection to define a gap therebetween into which the edge of the lid may fit.
  • the base portion may have lid supporting pillars.
  • the lid is provided with at least one finger-engaging aperture or cut-out or pull flap as means for facilitating the removal of the lid.
  • the container may be generally rectangular and the or each aperture, cut-out or pull flap may be provided at one side or end of the lid. It has been found that a side aperture, cut-out or pull flap can result in a smoother and thus easier removal of the lid.
  • the lid may be provided with one or more side and/or end flaps which fit inside the base portion.
  • the base portion may have article receiving depressions.
  • the container may be suitable for packaging eggs, fruit or other articles.
  • the container may be any other container having a separate lid thereon, but preferably a deep-walled container with a substantially flat lid.
  • an egg box comprises a base portion 10 formed of deep-drawn plastics material and a separate flat, cardboard lid 18.
  • the base portion has six egg receiving depressions 11 and two centrally arranged upstanding pillars 12 within a surrounding wall 13.
  • the upper edge of the wall 13 has a continuous internal shoulder or ledge 14 and a peripheral rim 15.
  • the ledge 14 is in the same plane as the upper surfaces of the pillars 12.
  • the height of the upper surfaces of the pillars above the biases of the depressions 11 is equal to or larger than the greatest dimension of the eggs to be packed in the egg box.
  • the lid 18 rests on the pillars 12 and the ledge 14, and may carry printed matter concerning the eggs packed in the box.
  • Retaining means for the lid 18 are provided which render the lid reclosable.
  • the retaining means comprise hollow hook-like projections 19 projecting upwardly from the pillars 12 through aligned D-shaped apertures . 20 ( Figure 3) in the lid.
  • Each projection is moulded integrally with the base portion 10 and is formed with a hollow stem 21 merging into a hollow lug 22 extending substantially perpendicularly thereto.
  • the lugs 22 of the two projections 19 face in opposite directions, in this embodiment away from each other, and when the lid is placed thereon, the lugs overlie the upper surface of the lid.
  • the lugs 22 may face each other. Also, in the case of an egg box for twelve eggs having four lid support pillars, there may be a projection 19 upstanding from each pillar or only two of the pillars as may be required.
  • Additional finger-engaging apertures or cut-outs 23 at the ends of the lid are provided to facilitate removal of the lid. These cut-outs 23 also serve as ventilation holes.
  • FIGS 4 and 5 relate to an alternative embodiment in which the lid retaining means are hollow projections 30 incorporated into the rim of the surrounding wall 13 of the base portion 10 instead of projecting upwardly from the support pillars 12.
  • the lid retaining means are hollow projections 30 incorporated into the rim of the surrounding wall 13 of the base portion 10 instead of projecting upwardly from the support pillars 12.
  • the lid 33 has apertures or cut-outs 34 at its ends to facilitate removal of the lid and to provide ventilation for the eqgs.
  • the lid may have one or more side and/or end flaps as described in British Patent Application No 2072628. Each flap fits inside the base portion and may rest on the walls defining the egg receiving depressions 11. Such a construction of lid allows the edge support ledge 14 to be omitted.
  • the continuous ledge 14 of the previous embodiments is replaced by a local ledge 40 associated with each projection 30 whereby the lug 31 and the respective ledge 40 still define a groove into which fits the edge of the lid.
  • This ledge 40 is provided by a substantially vertical, tapered rib formed internally of the surrounding wall 13, which rib is convex in cross-section with regard to the inside of the box and serves also as strengthening means for the wall 13.
  • Each projection 40 and its respective rib are formed during the moulding of the box 10 by a single tool comprising a vertical post 41 shown in chain-dot lines.
  • FIG 8 shows a detail of a still further egg box in which the turned over rim 15 is replaced by a flat rim 42 having a small upstanding rib 43 to provide strength to the rim.
  • This modification may be applied to each of the embodiments of Figures 1 to 3, Figures 4 and 5 and Figures 6 and 7.
  • each corner projection 30 would still be formed between two upstanding shoulders in like manner to the first embodiment of Figures 1 to 3, the remainder of the rim having the cross-section shown in Figure 8.
  • edge support for the lid than is given by the ledges 40 may be provided by any side or end flap resting on the adjacent walls defining the egg receiving depressions 11.
  • Figure 9 concerns an egg box which is of a similar type to the egg box described in relation to Figures 1 to 3.
  • the base portion 10 remains unchanged.
  • the apertures 44 in the lid 45 for engagement by the hook-like projections 19 upstanding from the pillars 12 are crescent shaped instead of being D shaped, the convex edge of the tongue 46 providing a flexibility thereto which results in an easier disengagement with the lug 22 of the respective projection.
  • the finger-engaging apertures or cut-outs 23 at the ends of the lid are also replaced by an equivalent aperture or cut-out 47 at one side, in this embodiment, or at each side of the lid 45.
  • Such side positioning of the lid removal means can be advantageous because the lifting movement of the lid is not directly opposed to the natural holding action of the lugs 22 of the projections 19.
  • the lid 45 of the embodiment of Figure 9 may be replaced by any of the alternative lids illustrated in Figures 10 to 16.
  • the lid 48 shown in Figure 10 there is provided a finger-engaging aperture or cut-out 49 at one end of the lid.
  • the lid removal means is a pull flap 50 at one end of the lid 51.
  • the lids 52 and 53 of Figures 12 and 13 are equivalent to the lids 48 and 51 of Figures 10 and 11 respectively, except that they have side flaps 54 which may be folded downwardly to be inserted inside the base portion 10 as described in Application No 2072628.
  • lids 55 and 56 of Figures 14 and 15 have a single end flap 57 instead of- two side flaps.
  • the lid 58 of Figure 16 has two end flaps 57 and at one end a pull flap 59 cut out of the flap 57 at that end of the lid.
  • the invention is not restricted to the specific details of the embodiments described above.
  • the ledge or ledges in the base portion which support the lid edge may be omitted, especially in the case of the lid having side and/or end flaps which can readily engage the top of the nests or pockets in the base portion.
  • the projections 19 may be directed towards each other or both projections may be directed towards one or other side of the box.
  • each aperture 20 or 44 would be correspondingly arranged to cooperate with the respective projection.
  • the peripheral location of the lid removal means may be altered, as desired, so that its action is best suited to the particular arrangement of interengaging projections and apertures.
  • each embodiment may be readily adapted to a container having, a different number of pillars.
  • a container of the same general type as shown in Figures 1 to 3 and 9 but for packaging twelve eggs may have four pillars each having an upstanding hook-like projection which passes through a respective aperture in the lid.
  • the four projections are all directed at their respective adjacent side of the box or are all directed at their respective adjacent end of the box, but other arrangements could be provided if desired.
  • the four projections may all be directed inwardly, either longitudinally or transversely of the box.
  • the container may also be readily modified for packaging any other number of eggs, e.g. ten.
  • the container may be a box for packaging any desired number of fruit or other articles instead of eggs.
  • the invention is also applicable to any container having a separate lid whether or not the container has article receiving depressions in its base portion.
  • a container is a deep-walled container having a substantially flat lid, and/or has one or more lid supporting pillars in its base portion.
