Definitions

  • 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 including an outer flange element, 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 the opposite side walls of said cover member side walls having at least one locking tongue which is situated on the inside of its respective side wall and which is inwardly biassed, each locking tongue 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 provide a container of the aforementioned kind, which provides a stronger and safer interlocking between the tray and cover members. This object will be achieved by a container according to the invention and having the characteristics set forth in Claim 1.
  • the outer flange elements consist 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 having 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 sequential stages for the manufacture 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 member has a plane bottom wall 1a and four side walls 1b-e up-standing from the bottom wall 1a to form a box-like structure open at the top.
  • Each tray member side wall 1b-e has an outer flange in the form of a brim 2, 3, 4, and 5, respectively, projecting outwardly from the periphery of the tray member in a direction substantially parallel to the plane of the bottom wall 1a 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, respectively, 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 15 - 18 such that the four side walls 11 - 14 will depend from the top wall 10 to form a box-like structure open at the bottom.
  • the side walls 11 - 14 have been cut out in a manner such that the box-like structure will converge conically downwardly.
  • the two longer side walls 12 and 14 have, at their ends, an extension portion 12a, 12b and 14a, 14b, respectively, which can, via fold lines 19 - 22, be folded inwardly at approximately right angles to the longer side walls 12 and 14, respectively, and be fastened, for instance by adhesive 23 - 26, to an adjacent short side wall 11 and 13, respectively, see Fig. 3.
  • Each end of the short side walls 11 and 13 has a fold line 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 flattened condition, see Fig. 5, which condition the cover member 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.
  • This will accomplish the special effect that the non-glued areas of the extension portions 12a-b and 14a-b, respectively, will move relative to its associate short side wall, when this is being infolded towards the top wall 10, as is seen in Fig. 4.
  • the nonglued 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 description below by reference to Figs. 6 and 7.
  • Fig. 6 is a perspective view, as seen obliquely from beneath, of a cover member according to the invention
  • Fig. 7 is a perspective view, as seen obliquely from beneath, of a 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 engagement with its associated aperture.
