Definitions

  • Container having an interlocking cover arrangement
  • This invention relates to a container, especially a food container, having an interlocking cover arrangement, the container having a tray member including a plane bottom wall and four tray member side walls upstanding from the latter to form a box-like structure open at the top, the tray member side walls each includes an outer flange ele ⁇ ment, the container also has a cover member including a plane top wall and four cover member side walls depending from said top wall to form a box-like structure open at the bottom, each of two opposite side walls of said cover member side walls having at least one biassed locking ton ⁇ gue presenting an upwardly facing abutment for engagement with a corresponding downwardly facing abutment on said tray member.
  • the object of the present invention is, therefore, to pro- vide a container of the aforementioned kind, which provi ⁇ des a stronger and safer interlocking between the tray and cover members.
  • This object will be achieved by a con ⁇ tainer according to the invention and having the characte ⁇ ristics set forth in Claim 1.
  • the outer flange elements con ⁇ sist of brims projecting outwardly from the periphery of the tray member in a direction substantially parallel to the plane of the bottom wall of the tray member, said ⁇ brims each having a bottom surface forming said downwardly facing abutment, and said brims each having a top surface forming an abutment surface for engagement with said top wall of the cover member, an opposed pair of the brims ha ⁇ ving apertures for mating engagement with each of said locking tongues by snap-action.
  • Fig. 1 is a perspective view of a tray member according to the invention.
  • Figs. 2 - 5 illustrate four seguential stages for the ma ⁇ nufacture of a tray member according to the invention.
  • Figs. 6 - 7 illustrate in sequence two operational stages in interlocking a tray member and a cover member according to the invention.
  • Fig. 1 shows a rectangular tray member 1 of a plane, stiff material, for instance a paperboard material.
  • the tray mem- ber has a plane bottom wall la and four side walls lb-e up ⁇ standing from the bottom wall la to form a box-like struc ⁇ ture open at the top.
  • Each tray member side wall lb-e has an outer flange in the form of a brim 2, 3, 4, and 5, re- spectively, projecting outwardly from the periphery of the tray member in a direction substantially parallel to the plane of the bottom wall la of the tray member.
  • the tray member may be either right-angled or conical in order to enable a piling of several tray members into one another.
  • the tray member may also be foldable, for instance of the type described in Swedish patent specification Number 8405157-2.
  • Each of the two opposed brim portions 2 and 4 see Fig. 1, has two through, oblique apertures 6, 7 and 8, 9, respec ⁇ tively, which improve the interlocking function, as will be explained below.
  • Fig. 2 shows a cut out plane blank of a plastic treated paperboard or the like, which, after folding and glueing, will form the cover member illustrated in Figs. 3 - 5.
  • the cover member has, see Fig. 2, a plane top wall 10 and four rectangular cover member side walls 11 - 14 foldable downwards at approximately right angles via fold lines
  • the two lon ⁇ ger side walls 12 and 14 have, at their ends, an exten ⁇ sion portion 12a, 12b and 14a, 14b, respectively, which can, via fold lines 19 - 22, be folded inwardly at appro ⁇ ximately right angles to the longer side walls 12 and 14, respectively, and be fastened, for instance by adhesive
  • Each end of the short side walls 11 and 13 has a fold li ⁇ ne 27 - 30, respectively, extending in about 45 degrees from a respective one of the corners of the top wall 10.
  • These fold lines 27 - 30 enable an infolding of the short side walls 11 and 13 towards the top wall 10, see Fig. 4, to permit the cover member to be collapsed into a flatte ⁇ ned condition, see Fig. 5, which condition the cover mem ⁇ ber will have during transport prior to packing of the tray member.
  • the adhesive 23 - 26 has been applied only to a triangular area, see Fig. 2, at the end of each short side wall 11 and 13, which area is located outside the respective fold line 27 - 30, thus causing only a corresponding triangular area of the extension portions 12a-b, 14a-b, to be glued to an associated one of short side walls 11 and 13.
  • the outermost area of the extension portions 12a-b and 14a-b, respectively will remain free from the adhesive and will not be glued to its associated short side wall 11 and 13, respectively.
  • the non- glued areas of the extension portions 12a-b and 14a-b, respectively, can, thereby, be used as a kind of locking tongues, which can be said to be indirectly biassed by said inherent springiness of the paperboard material of the short side walls of the tray member.
  • the function of these locking tongues will be apparent from the descripti- on below by reference to Figs. 6 and 7.
  • Fig. 6 is a perspective view, as seen obliquely from be ⁇ neath, of a cover member according to the invention
  • Fig. 7 is a perspective view, as seen obliquely from beneath, o ⁇ H tray member 1 with a cover member telescoped over the tray member.
  • the effective locking depth provided by the apertures 6 - 9 is in fact greater than the thickness of the brims 2 - 5. Namely, in practice, the brims 2 - 5 will not be oriented exactly in parallel with the top wall 10 of the cover member, but will incline a few degrees, such that the locking tongues, when moving through the apertures, will move a certain distance past the apertures, which will cause a still stronger interlocking between the tray and cover members.
  • the length of the extension portions 12a-b and 14a-b and the configuration, location and angle of the apertures 6 - 9 is dimensioned such that the non-glued areas of the extension portions (i.e. the "locking tongues") or their heels or hooks 33 - 36, if such are present, will obtain the same direction and location as the apertures in order to ensure that the locking tongues will get an optimal en ⁇ gagement with its associated aperture.
