Definitions

  • the invention relates to a stackable crate made of foldable flat material, which has stacking cams in the corners and on which the crate arranged below can be adjusted.
  • Containers for fruit, vegetables, young plants, meat, fish, baked goods or other goods are made from wood, chipboard, corrugated cardboard or plastic.
  • Known plastic crates are injection molded or deep drawn in a very complex manner. Ridges usually have suitable stacking edges so that they can be stacked on top of one another without adversely affecting the material picked up.
  • massive or hollow supports can be provided in the corners.
  • the empty crates also known as rotary stack crates
  • crates made of corrugated cardboard offer the advantage that the blanks can be delivered and stored flat.
  • such crates have a short lifespan because, even when coated, they are sensitive to moisture. They can therefore only be reused to a limited extent and are not space-saving.
  • the invention is therefore based on the object to provide a reusable stackable crate that Delivered as a flat blank and empty
  • Condition nested i.e. can be stored and transported in a space-saving manner.
  • stacking cams are formed in the four corners, which consist of two cam sections, which are articulated to one another via a creasing line and are articulated on their respective other sides to the associated side wall in such a way that they are in the stacked state - use -State - form a square hollow support with the riser corners and, when empty, by applying diagonal pressure from the inside of the riser, overcoming a dead center position, can be put back on the riser corners, the crease lines between the cam sections largely coinciding with the assigned corner edge.
  • the tray according to the invention is made of foldable flat material.
  • a stacking cam which consists of two cam sections, which are each articulated to the side walls, is preferably arranged in each corner. The articulation is such that the cam sections can form a hollow support with the side walls in the corner areas.
  • a stacking cam is also formed when the cam sections extend only over part of the height of the side walls, the cam sections advantageously being supported on the bottom of the tray. If pressure is exerted on the cam sections articulated in this way from the inside of the crate, the cam sections snap into the corner and lie on the associated side walls. As a result, the tray has quasi flat inner walls.
  • the crate is designed in such a way that it is smaller in plan than in the outline at the top.
  • the stacking cam is activated by simple pressure from the outside, ie it projects into the inside of the tray.
  • the cut of the crate according to the invention is produced in one piece.
  • the invention is not limited to a one-piece blank.
  • a first cam section is articulated on one side wall and the second cam section can be fastened to the other side wall via a support tab.
  • the attachment can take place, for example, by gluing or welding.
  • the support tab also advantageously extends to the bottom of the crate. In the case of a trapezoidal configuration of the cam sections and when the support bracket extends to the floor (in the installed state), the material for the lower regions of the second cam section and the support bracket is to be removed from the associated side wall.
  • an embodiment of the invention provides that starting from the base point of the crease line between the cam sections, an additional crease line is formed at an angle of 45 ° to this crease line up to the upper edge of that side wall, to which the first cam section is articulated. With machine gluing and. Folding the cam sections with the support flap and the remaining part of the side wall are folded onto the corresponding side wall and the floor by 180 °. Then the other side wall is also folded by 180 ° with the retaining tab on the back of the parts described.
  • the support bracket is glued to the associated side wall and the retaining bracket to the outside of the associated side wall.
  • an opening is provided in the transition from the holding tab to the associated side wall, through which an external pressure can be exerted on the crease line between the cam sections.
  • stabilizing tabs can be articulated on the upper ends of the cam sections, which are interlocked with one another in the erected state.
  • a further embodiment of the invention provides that on opposite. Side panels are hinged to the sides, the anchoring tabs at the corners have in the anchor slots of the other
  • Sidewall can be anchored.
  • the frame flaps are folded inwards by approximately 90 ° with respect to the assigned side walls.
  • the anchoring tab is anchored in the anchoring slot.
  • the length of the frame flap is shorter than the overall outer length of the crate.
  • the anchoring slot is reversely T-shaped and receives an anchoring tab which is molded onto the frames via a twistable neck.
  • the facing of the benach ⁇ disclosed climbing corner portion 'of the crosspiece of the T is preferably longer than the other transverse web portion.
  • the longitudinal web of the T preferably merges with a curve into the two crossbar sections, the curve with the longer crossbar section having a larger radius than the other curve. If the frame is folded 90 ° toward the inside of the riser, and at the same time the anchoring flap is twisted by a further 90 °, the neck can be inserted into the anchoring slot from above. Once at the crossbar of the T, the anchoring tab is twisted by 90 °.
  • the frame flap can be released just as easily if the crates are to be nested in one another when the stacking cams are pressed in. Instead of gluing during erection, the parts of the trays to be connected to one another can also be connected to one another manually by means of suitably designed locking sections. Unwanted movements of all the parts involved can be virtually ruled out by suitable configurations.
  • the mobility of the stacking cams is not reduced, nor is their strength.
  • the support bracket can be fixed with the aid of a locking bracket that is locked in a slot in the associated side wall.
  • the retaining tab can also be connected to the associated side wall via a pluggable locking connection.
  • the hollow support according to the invention has three fully supporting right angles, which are preferably the. full-height of the S have increasing and then its four side surfaces and with three right angles up directly on the tray bottom.
  • the fourth side surface is formed by at least two thirds of the height of the tray from the retaining tab, which is also firmly connected to the side of the tray assigned to it. In this way, the required transverse stability is also achieved and ensured.
  • the stacking cams are advantageously provided with centering guides formed as quarter circles on two of their upper edges, each starting from the angular regions on the longitudinal or end faces. These centering guides have the effect that the stacked, filled crates remain in the solder and cannot move because the crate bottoms are less than the upper edges due to the taper.
  • the radius of a quarter circle can be half the difference in length or width from the bottom to the top
  • REPLACEMENT LEAF match the climb. This prevents the stack from tipping over.
  • double-wall sheets which are made, for example, of polypropylene.
  • double-wall sheets two outer layers or outer layers are connected to one another by spaced-apart transverse webs.
  • this material is best compared to corrugated cardboard. Compared to corrugated cardboard, however, it has a much higher stability and a better durability as well as a complete insensitivity to water or moisture.
  • the outer layers are welded to one another at the cut edges of the cut approximately in the center of the caliber of the double-wall sheet.
  • the cut edge is completely closed. This prevents dirt particles and / or moisture from penetrating into the hollow chambers of the double-wall sheet. For hygienic reasons, it is advisable to prevent such penetration. Welding the outer layers completely prevents such penetration.
  • the support tab and / or the retaining tab can be glued to the associated side walls of the tray. Alternatively, they can be welded to one another when using double-wall sheets.
  • an embodiment of the invention provides that the support bracket and / or the retaining bracket is welded to the associated side wall and that in the welded area the outer layer in each case is welded against it in the plane of the inner outer layer.
  • the areas to be welded are preformed in such a way that the outer layer in each case is deformed into the plane of the inner outer layer and are welded to one another over both layers. When the parts are welded together, four outer layers are close together.

  • the creasing line 10.2 runs in such a way that both cam sections 11 are trapezoidal. Since the cam section 12 is congruent with the cam section 11 and is trapezoidal, its lower region, as can be seen from FIG.
  • a support tab 15 is articulated to the cam section 12 via a crease line 12.1. It tapers in the lower area to its base, so as not to use too much material from the end wall 3.
  • the support tab has an approximately trapezoidal recess 15.1, which has a narrow cross section, as a result of which two cams 16 are formed.

  • the locking tab 18 without the wings 18.2 has a width that approximately corresponds to the width of the recess at its end.
  • the cams 16 are therefore at a smaller distance than this width, so that they counteract pivoting of the locking tab when inserted into the slot 17 (see also FIGS. 3 and 4).
  • the wings 18.2 pass through the incisions 17.2 and then spring against the rear side of the cam section 12. Due to the diverging sides of the receiving slot 17 from the crease line 12.1, the locking tab 18 is increasingly locked when a pull is exerted thereon. This connection is also secured against train and pressure.
