Definitions

  • the invention relates to a stackable storage and transport container, in particular for fruit, vegetables or dairy products, from a one-piece blank, for example made of plastic, corrugated cardboard or cardboard, the side walls of the square container having inward bends at the corners of the container, the cavities form, into which rigid stack supports are removably inserted, which protrude both with their upper and with their lower end regions over the bends and rest in the erected state of the blank on inwardly folded flaps of the blank and thereby arrest the erected state of the blank, and where in the erected state of the blank, fix the stacked-up parts of the stacked containers in their relative position.
  • a one-piece blank for example made of plastic, corrugated cardboard or cardboard
  • the side walls of the square container having inward bends at the corners of the container, the cavities form, into which rigid stack supports are removably inserted, which protrude both with their upper and with their lower end regions over the bends and rest in the bends and rest in the erected state of the
  • Containers of the type described are known from AT-PS 367 369. They have the advantage that the blank can be laid flat after removal of the stack supports from the cavities formed by the bends and can thus be stored in a space-saving manner. In the erected state of each container, this forms a relatively rigid trough, with containers stacked one on top of the other being held securely against slipping.
  • the stack supports divert the pressure of the filling material downwards, so that high stacking heights can also be achieved with heavy filling material, for example peaches, so that the like in the storage space. can be stacked to save space.
  • the stack supports are formed from molded plastic parts with an essentially L-shaped cross section, the size of which increases from bottom to top in accordance with the wall inclination of the outwardly inclined container side walls. This requires a special production of these stack supports, so that such stack supports are relatively expensive.
  • the invention has for its object to avoid these disadvantages and to improve a container of the type described so that the manufacture of the stacking supports is easier, so that the price of the container can be reduced compared to the known construction described at the outset to forego their advantages. Furthermore, the edges described should be avoided or closed be mitigated at least.
  • the invention solves this problem in that, in the case of a container of the type described above, each stacking support has a constant circular cross section over its entire length, the cavity, which is limited by the bends and which receives the stacking support, also has a cross section which is constant over its entire height. While the cross-section of the cavity and the stack support increases conically upwards in the known construction described at the outset, this is not the case in the construction according to the invention.
  • the stacking support easier to manufacture, since it can be assumed that the bar material has a constant cross section and is simply cut to the required length.
  • the circular, constant cross-section of the stack support also makes it possible to insert it in any angular position and / or upside down into the cavity delimited by the deflection, which is not possible with the known construction described at the beginning.
  • the round cross-section of the stack support results in the elimination of a sharp edge which acts on the deflection, since the lateral surface of the stack support is round in its area interacting with the deflection. This also avoids sharp edges on the walls forming the bend, so that the contents in the filling space of the container are better protected.
  • each stack support is expediently formed by a tube section, in particular made of cardboard, hard paper or plastic. This results in a particularly high load-bearing capacity, since a pipe has a higher bending and kink resistance compared to a round full cross-section of the same size and less weight.
  • each stacking support which is circular cylindrical in cross section is slightly oblique with respect to the bottom of the container ters stands and ends below the upper edge of the outwardly inclined side walls.
  • the invention can also be applied to containers with trough-widening side walls.
  • the slight inclination of the stack supports does not matter for the derivation of the stack pressure if the angle of inclination is not too large.
  • the anti-slip protection results from the upper wall parts of the respective lower container, which embrace the lower part of the respective upper container.
  • the arrangement can also be such that the upper end of each stack support with a circular cylindrical cross-section extends to the upper edge of the side walls and that stacked containers are fixed in place from the upper edge of the side walls by tongues which are arranged in correspondingly arranged recesses can be used in the bottom of the container above the stack.
  • each end face of the stacking support in a flat manner and with an end face extending normal to its longitudinal axis. This not only makes it easier to cut off the stack supports from rod material, but also preserves the advantage already mentioned that the stack support can be used in any rotational position with respect to its longitudinal axis.
  • the slight misalignment of the ends of the stacking support with respect to the bottom of the container does not matter, since the edge part closer to the bottom is pressed into the mostly flexible material of the container base under load, which at the same time creates a further centering and anti-slip protection.
  • FIG. 1 shows an exemplary embodiment with container sidewalls inclined outwards in an axonometric view, one stack support being pulled out and three stack supports being shown inserted.
  • 2 shows the blank of the container belonging to FIG. 1 in the flat state.
  • 3 shows a section along the line III - III of FIG. 1 on a larger scale.
  • 4 shows a second embodiment, provided with side walls standing normally on the floor, in a representation similar to FIG. 1.
  • 5 is the blank belonging to FIG. 4 in the flat state.
  • Figure 6 is a section along the line VI - VI of Figure 4 on a larger scale.
  • the container consists of a blank 1 shown in FIG. 1 when it is erected and in a flat state in FIG. 2, as well as four stack supports 2 that fix the blank 1 in the erected state
  • Cardboard, cardboard, corrugated cardboard or plastic in particular made of plastic multi-wall sheet material, in which tear-resistant reinforcing inserts, for example glass fibers, rovings, wire or the like, in a thin plastic plate. are embedded.
  • the stack supports 2 consist of pipe sections made of cardboard, hard paper or plastic.
  • the blank 1 consists of a rectangular base 3 and four side walls 4, 5, 6, 7 extending from it, of which the side walls 5, 7 forming the longitudinal walls are each provided with an extension 8 at their ends.
  • each of the other two side walls 4 and 6 has on its upper edge a tab 9, which ge in the erected state of the blank 1 down folds and runs parallel to the associated side wall 4 or 6 and serves to lock the blank 1 in the erected state.
  • the parts of the blank described are connected to one another via folded edges 10, so that the blank parts described form an integral blank 1.
  • two incisions 11 crossing these folding edges 10 are arranged, the ends of which are each connected in pairs by further folding edges 12.
  • bends 13 are formed which are pressed inwards when the blank 1 is erected and in this way, together with the side walls 5, 7 and their extensions 8 or the imaginary extensions thereof, delimit cavities 14 (FIG. 1) into which the stack supports 2 can be inserted.
  • the outer diameter of each stack support 2 formed by a tube section is dimensioned such that the stack support 2 fits snugly into the cavity 14, so that the stack supports 2 cannot fall out of these cavities 14, but can be pulled out without difficulty.
  • Each stacking support 2 protrudes above and below the upper edge 15 and the lower edge 16 of the bend 13 so that the stacking support 2 can rest there on the side walls 5, 7 or the extensions 8.
  • the tabs 9 are folded inwards, which in the folded-in state end above the bends 13 (FIG. 3) and are held by the upper end sections 17 of the stack supports 2. As a result, the blank 1 is locked in the erected state. There are therefore no other aids such as brackets or the like. to hold the blank 1 in the erected state necessary.
  • Each stacking support 2 consists of a tube section made of cardboard, hard paper or plastic. Each end 18 (Fig.3) the stack support 2 is cut off normal to its longitudinal axis. Between the plane of this front end 18 and the plane of the bottom 3 there is therefore a small acute angle ⁇ , which is essentially the same as the angle of inclination of the side wall 4 of the container relative to the vertical (FIG. 3). This slight misalignment of the stack support 2 does no harm, since that side of the front end 18 which rests on the base 3 is pressed into the material of the base and thus forms an additional fixation for the stack support 2.
  • each stack support 2 has a constant cross section over its entire length. This also ensures that the stack supports 2 are inserted into the cavities 14 up to the bottom 3 of the container can be pushed.
  • the usable filling height of the container can be adapted to the respective filling material, thereby saving on transport space.
  • the shorter side walls 4, 6 of the container are provided with cutouts 20 which form grip holes, on the upper edges of which reinforcement tabs 21 are provided.
  • the bends 13 can have a central folded edge 22, as shown in Fig.1.
  • This folding edge 22 expediently runs flush with the folding edge 10.
  • the folding edge 22 can also be omitted, so that the inner surface of the bend 13 facing the filling space is without folds and edges, that is to say it has a round cross-section if the material of the bends 13 permits a round bend. which is mostly the case.
  • the wall of the bend 13 in the erected state of the blank 1 automatically adapts to the round outer surface of the stack support 2. This not only improves the fit of the stack support 2, but also avoids a sharp edge that is directed towards the filling space of the container.
  • FIGS. 4 to 6 differs from that according to FIGS. 1 to 3 primarily in that the side walls 4, 5, 6, 7 of the container run normal to the plane of the bottom 3. Accordingly, the stack supports 2 are also vertical and the axes of the cavities 14 formed by the bends 13 also run vertically.
  • the end faces 18 of each stack support 2 are also cut off normal to their longitudinal axis here, but these end faces lie flat against the floor 3. In the inserted state of the stack supports 2, their upper end faces 18 lie at the same height as the upper edge 19 of the adjacent parts of the side walls 4, 5, 6, 7.
  • each container has on each of the shorter side walls 4.6 two tongues 23 which project upwards from the upper edge 19 of these side walls and engage in correspondingly arranged recesses 24 in the base 3 or in the lower parts of the side walls 4, 6 of the container lying above them in the stack.
  • the container can furthermore have elongate tabs 25 connected to the upper edges 19 of the longer side walls 5, 7, which, when the container is erected, lie horizontally and form additional contact surfaces for the container lying above it in the stack.
  • These tabs 25 can carry extensions 26 on their lateral longitudinal edges, which are connected to the tab 25 via bending lines 27 and can be inserted into corresponding openings 28 ah the upper edges 19 of the shorter side walls 4, 6.
  • These openings 28 expediently lie on the inside of the tongues 23, as a result of which the tongues 23 are stiffened by the downwardly angled extensions 26.
  • the bottom and the walls of the container can also have ventilation openings for the filling material in a manner known per se.
