Definitions

  • the present invention relates to a container for holding goods, for example for foods such as pizza or the like, according to the preamble of claim 1.
  • Containers are known which are designed in the form of a shell from aluminum for the transport of foodstuffs, in particular hot dishes. Due to an inclined, outwardly diverging arrangement of the edge walls, several such containers can be stacked in a very space-saving manner when empty, in that they can be placed one inside the other.
  • This known container is closed with a separate lid, which consists of a flat blank and is placed on a support edge of the bowl-like container and is then fixed by flanging an edge web extending upwards over the support edge. This makes the closure of the container cumbersome and uncomfortable, especially for hot dishes.
  • So-called pizza boxes are furthermore known - see, for example, US Pat. No. 5,014,853, which are usually traded as flat blanks made of cardboard or cardboard and therefore disadvantageously only in a state ready for use by the user and ready to accept the respective contents. " have to be unfolded ". This is cumbersome and time consuming.
  • such containers can be made ready for use, i.e. ready-to-shoot condition can only be stored extremely poorly, since they can only be stacked on top of each other and therefore require considerably more storage space than the original cuts.
  • the stacks are extremely unstable and are therefore subject to the constant risk of tipping over.
  • the cover part is foldably connected to the lower part, so that only the cover part is folded over onto or into the lower part for closing.
  • an absolutely flat upper surface is then present in the closed state, so that here too several closed containers placed one on top of the other can slide against one another.
  • a food container which also consists of a lower part and a cover part, but the lower part has side walls which extend at right angles to the floor, so that several lower parts are not safe and ready for use can be stacked in one another to save space.
  • Only the upper part has walls diverging obliquely outwards from a cover wall. The upper part engages with the walls in the lower part.
  • Document DE-A-25 54 034 used to form the preamble of claim 1 describes a "container” in which on the one hand a “conicity” and a space-saving stackability resulting therefrom in the empty state and on the other hand one for forming edge webs as “stacking” Anti-slip protection "(when filled) cover wall offset downwards are realized. Furthermore, the cover part is supported on the base of the lower part by means of edge webs engaging in the lower part, but in some cases only indirectly via narrow flaps. Good stability is achieved in this way, so that several filled containers can be stacked.
  • the one-piece and articulated lid with the lower part has two shoulders in the side edge region of a front flap, which should "cooperate” with corresponding shoulders in the lower part when the lid is closed. Presumably, this should lock the lid against opening, but at best in combination with the foldable connection of the bottom and lid parts provided here opposite should be sufficient.
  • this solution is only suitable for folding blanks with flaps that are folded inwards in the lower part.
  • the present invention is therefore based on the object of creating a container of the generic type which, while maintaining a good and space-saving or safe against slipping stackability in the empty and filled state, is particularly good and comfortable to use and, with a structurally simple design, also has a good locking mechanism the lid part in the closed position guaranteed.
  • a container 1 according to the invention consists in all versions of an essentially shell-like lower part 2 for holding food or any other objects (goods) and a lid part 4 serving for closing the lower part 2.
  • the lower part 2 consists of an at least approximately flat bottom 6 as well as Edge walls 8 which delimit an upwardly open receiving space 9 of the lower part 2 on all sides.
  • Edge walls 8 which delimit an upwardly open receiving space 9 of the lower part 2 on all sides.
  • the edge walls 8, starting from the edge of the base 6, extend upwards away from the latter, and at least some of the edge walls, but preferably all the edge walls 8, also extend at an obtuse angle, diverging obliquely outwards.
  • each edge wall 8 includes an obtuse angle ⁇ with the bottom 6, which is between 90 ° and 180 °, preferably in the range of approximately 50 ° to 80 °.
  • the cover part 4 mainly consists of an at least approximately flat cover wall 10, which covers the receiving space 9 of the lower part 2 from above in a closed position which closes the lower part 2.
  • the lower part 2 or its base 6 is rectangular, in some cases in particular square, and consequently has four edge walls 8 which are connected or connectable in pairs in the corner regions of the lower part 2. Consequently, the lower part 2 has the spatial shape of an inverted truncated pyramid, which - as already mentioned - ensures the stackability. This shape of the lower part 2 could also be described as "quasi-conically expanded". Because of the shape of the lower part 2 described as preferred, the cover part 4 or its cover wall 10 also has a rectangular or square shape in the main. However, the invention is by no means limited to the rectangular or square shape of the lower part 2 and the cover part 4; rather, other geometric shapes such as circular, oval, polygonal or the like would also be possible.
  • the edge walls 8 delimit a container opening (not designated) which lies in a plane 14, which is consequently defined by the upper edges 12 of the edge walls 8 (see in particular the cross sections in FIGS. 6, 17 and 18).
  • the cover wall 10 in the closed position of the cover part 4, lies in a plane 16 which is arranged in the region between the plane 14 defined by the upper edges 12 of the edge walls 8 and the bottom 6. This means that the cover wall 10 or the level 16 is arranged below the level 14 and thus somewhat sunk into the lower part 2.
  • the cover wall 10 is practically already within the receiving space 9 of the lower part 2.
  • the level lies 16 preferably only slightly below the level 14 of the upper edges 12, that is, just so far below that at least some of the edge walls 8 in some areas form upwardly projecting edge webs 18 with such a height that a set up on the closed container 1 Lower part 2 of another container 1 is fixed against lateral slipping.
  • a height of the edge webs 18 in the range of 3 to 10 mm is sufficient for this; the height is preferably 5 to 8 mm.
  • taller containers cf. FIGS.
  • the cover wall 10 may well be “lower” below the level 14, for example in the range from 20 to 40 mm, in particular approximately 30 mm.
  • This expedient embodiment advantageously allows a plurality of closed containers 1 to be stacked one on top of the other, a high level of security against lateral sliding of the containers relative to one another being ensured.
  • the edge webs 18 can be formed at least in the corner regions of the container 1, but can also easily extend over the entire circumference, or only in the region of two opposite edge walls 8.
  • cover part 4 in order to simplify the "assembly", ie the placement on the lower part 2, in the closed position and can be locked to the lower part 2 via at least one snap-fit form or force fit connection 20.
  • the cover part 4 has edge webs 22 according to the invention, which are arranged at an angle to the cover wall 10, namely the edge webs 22 starting from the cover wall 10 in the direction of the base 6 downward, so that they in of the closed position (see in particular FIG. 6) engage in the lower part 2 and are then supported on the bottom 6 and preferably also at least approximately over the entire surface, rest non-positively on the edge walls 8.
  • the edge webs 22 are accordingly adapted to the angle ⁇ of the oblique edge walls 8 of the lower part 2 with respect to their arrangement at an angle to the cover wall 10.
  • An edge web 22 is preferably formed on each edge of the cover wall 10, which is in particular square here, so that the cover part 4 here has four edge webs 22. Because of this advantageous embodiment, the cover part 4 only needs to be inserted into the lower part 2 with the edge webs 22, as a result of which sufficient locking is immediately ensured by frictional engagement.
  • the edge webs 22 of the cover part 4 are connected to the cover wall 10 so that they can be folded over, and in an initial position they lie in one plane with the cover wall 10 (see FIG. 4).
  • the edge webs 22 are expediently about Fold lines 24 are connected to the cover wall 10 (FIG. 4), these fold lines 24 being formed by linear material weakenings, for example by scoring and / or perforations or as so-called film hinges.
  • the edge webs 22 then only need to be folded over and inserted into the lower part, in which case the angle arrangement is practically automatically adapted to the oblique edge walls 8.
  • cover wall 10 is adapted in terms of its shape and size to that surface which is defined or enclosed by the edge walls 8 of the lower part 2 at the level of the plane 16 of the cover wall 10. This can also be clearly seen in particular in FIG. 6.
  • a locking is provided according to the invention via at least one snap-fit form / force-fit connection 20.
  • the embodiment of this connection 20 according to the invention is shown in FIGS. 9 and 10 and in FIGS 16 to 18 and will be explained in the following.
  • the container 1 has four somewhat different connections 20, each of which is formed in the area of the square sides and each of which is formed at the upper edge of the respective edge wall 8 of the lower part 2 and has an upwardly open recess 26 and one in the plane the cover wall 10 lying and extending laterally beyond this, in particular approximately oval locking tab 28 of the cover part 4 exist.
  • Each marginal, narrow recess 26 widens in their two lateral end areas in the direction of the bottom via undercuts in such a way that two lateral locking lugs 30 facing each other are formed which, in the closed position of the cover part 4, each have their locking tabs 28 "snapping", ie latching (positive or non-positive), and so on lock securely.
  • the locking tabs 28 are advantageously cut free from the edge webs 22, so that after the edge webs 22 have been folded over, the locking tabs 28 each remain in the plane of the lid wall 10 projecting therefrom (see FIG. 3 and 4). Accordingly, the fold lines do not extend over the area of the locking tabs 28.
  • the support webs 34 can either be folded inwards so that the cover wall 10 then rests thereon, or they can be folded outwards, in which case the locking tabs 28 rest. In the folded-in state, the support webs 34 also pass through openings 36 of the edge walls 8 of the lower part 2 formed due to the cut-out locking tabs 28 (see the left part in FIG. 6).
  • the cover part 4 is extremely firm and secure on the lower part 2 lock, in this embodiment the locking tabs 28 can advantageously also be used in the closed position as carrying handles for the container 1 according to the invention. This makes carrying the container 1 particularly convenient, especially when it contains hot food, because touching the lower part 2, which is also hot, can be avoided.
  • FIGS. 7 and 8 corresponds in some basic details to that according to FIGS. 1 to 6. To this extent, parts with the same reference numbers can be referred to the above description, and only the special features and differences will be explained in more detail below.
  • the container 1 has only two form / force-fit connections 20.
  • the cover part 4 has a locking tab 28 in the area of two diametrically opposed side edges and two diametrically opposed edge webs 22 in the area of the other two side edges.
  • support tabs 38 are formed on the edges of the cover part 4 which have the edge webs 22 and which laterally protrude from the cover wall 10 in the plane thereof and are located in the closed position in the region of edge recesses 40 of the edge walls 8 of the base part 2 (see FIG. 8 ) lean on this.
  • the support tabs 38 are preferably cut out of the edge webs 22, essentially analogously to the locking tabs 28 of the embodiment according to FIGS. 1 to 6.
  • the lower part 2 corresponds essentially to that of FIGS. 1 to 6, but here are the Formation of the recesses 26 cut-free support webs 34 each practically divided in two with a central, recessed intermediate space, these intermediate spaces forming the recesses 40 for the support tabs 38 when the support webs 34 are in their not yet folded state lying in the plane of the edge walls 8 .
  • each of the edge walls 8 of the lower part 2 is advantageously designed identically, which has the essential advantage that the cover part 4 in each of four positions rotated by 90 ° in the plane of the cover wall 10 (and not only in two positions rotated by 180 ° ) can be brought into the closed position.
  • both the locking tabs 28 and the recesses 26 provided for this purpose have a greater length than FIGS. 1 to 6, ie they extend over more than half of the respective edge length.
  • the cover part 4 (FIG. 9) has according to the invention at its edges a plurality, in particular four per edge, lying in the plane of the cover wall 10 and projecting laterally therefrom.
  • the lower part 2 (FIG. 10) has a slot opening or a locking hole 44 in the corresponding upper region of the edge walls 8.
  • These locking holes 44 are preferably each in this embodiment approximately semicircular, with an arcuate hole edge pointing upwards and a straight hole edge forming a lower support for the respective locking lug 42.
  • the cover part 4 can simply be pressed into the lower part 2, with each locking projection 42 then snapping into one of the locking holes 44 with slight elastic deformation.
  • the cover part 4 also has edge webs 22 according to the invention, which essentially correspond to the embodiment according to FIGS. 1 to 6. The locking lugs 42 are then cut out of the edge webs 22 in an analogous manner.

  • All existing fold lines of the blanks 56, 58 which have already been described above, are formed as linear material thinnings or weakenings, for example by scoring and / or perforating.
  • the connecting tabs 60 are cut out of the blank 56; 2 shows corresponding cutouts 64 with a somewhat exaggerated width for the sake of clarity.
