Definitions

  • the present invention relates to a stackable box according to the preamble of patent claim 1.
  • the stacked boxes are essentially placed on top of each other in their corner areas.
  • the top sides of the side wall sections between the corner areas are inclined obliquely to the stacking direction.
  • This has the advantage that water and/or other liquids or moisture run off from the sloping tops of the side wall sections following the gradient and so the tops of the side wall sections dry more quickly. This is particularly advantageous if the boxes are used in a washing and/or rinsing process.
  • a disadvantage of the construction according to the EP 1 287 780 B1 is that the maximum possible load capacity of such boxes is limited.
  • the object of the invention is therefore to improve generic stackable boxes in such a way that, on the one hand, they have side walls that dry as quickly as possible, but on the other hand they also enable high loads.
  • the invention proposes a box according to claim 1.
  • the areas of the top side of the side wall sections remaining between the contact surfaces are designed to be inclined obliquely to the stacking direction, so that water and other liquids flow quickly from the top sides of the side wall sections, thus promoting rapid drying of the side wall sections.
  • the contact surfaces that protrude over the respective adjacent areas can be attached both to the tops and to the bottoms of the side wall sections.
  • Stackable boxes according to the invention could also be referred to as transport and/or storage boxes or generally as containers or transport containers. Even if they are designed for mechanical gripping using at least one gripping device, they can of course also be conveniently gripped and transported by hand.
  • mechanical gripping is to be understood in its general meaning as meaning that a box is physically contacted by means of a gripping device in such a way that it is lifted with the gripping devices in the mechanically gripped, in other words, machine-contacted or machine-touched state , transported or moved in another way.
  • Stackable boxes according to the invention can be used in very different areas. In principle, it is conceivable to use such stackable boxes for storing, washing and transporting dishes, glasses and the like. However, such machine-graspable stackable boxes are particularly preferably used in an industrial environment in order to store, transport, wash and the like corresponding objects to be processed, manufactured or manufactured in industry.
  • the minimum load capacity of stackable boxes according to the invention is advantageously at least 10 kg, particularly preferably 25 kg per box.
  • Stackable boxes according to the invention can also be dimensioned very differently. These are preferably boxes with a rectangular or square basic shape.
  • the length of the box is advantageously in the range from 10 cm to 120 cm, preferably from 25 cm to 65 cm, and its width in the range from 10 cm to 100 cm, preferably 25 cm to 45 cm.
  • the height of the box is in the range from 3 cm to 25 cm, preferably from 4 cm to 15 cm.
  • Boxes according to the invention can consist of different materials or material compositions. These can be metal boxes but also plastic boxes. Even wooden or composite boxes are conceivable. In any case, it is preferably provided that the stackable box is designed in one piece. This also means that the side wall and the floor are then connected to one another in one piece and are made of the same material.
  • boxes according to the invention can be those made of a suitable plastic such as polypropylene (PP), polyamide (PA), polyoxymethylene (POM) or polybutylene terephthalate (PBT). Boxes according to the invention can be produced, for example, using the injection molding process.
  • Boxes according to the invention have a base which, together with the surrounding side wall, delimits the receiving space of the box into which the objects can be placed.
  • the box is usually placed on the floor with the bottom in such a way that the objects in the receiving room rest on the floor.
  • the floor usually forms the support surface for the objects in the storage space of the box.
  • the recording space is limited by the circumferential side wall of the box.
  • the side wall can be self-contained and completely surround the floor. But it can also be made up of several components that are interrupted. Even then it can still be a circumferential side wall. Both the side wall and the bottom can be designed as self-contained surfaces.
  • the circumferential side wall is composed of corner areas and, preferably straight, side wall sections running between the corner areas.
  • the side wall can have a rectangular basic shape in a top view of the box.
  • the term rectangular is not only to be understood in the strict mathematical sense. It also includes embodiments in which the side wall sections basically converge at a right angle in the corner area, but the corner area itself still has roundings and the like, etc.
  • boxes according to the invention are designed so that they can be stacked on top of one another in a stacking direction together with other boxes of the same type.
  • the stacking direction is generally predetermined by the shape of the box or its bottom and side wall.
  • the floor can protrude over the side wall, so that this protruding area of the floor of a box can be placed in the upper area of the receiving space of the box underneath, i.e. in the area which is surrounded by the side wall, so that the floor of the upper box is closed is held positively on the sides by the side wall of the lower box.
  • This also automatically determines the corresponding stacking direction in which the boxes must be stacked on top of each other.
  • the features according to the invention must be implemented with respect to at least one stacking direction so that it is a box according to the invention.
  • the bottom forms an upper, in particular flat, boundary surface with which it delimits the receiving space.
  • the stacking direction then conveniently runs normal to this upper boundary surface of the floor. In other words, the stacking direction then forms a surface normal to this upper boundary surface of the floor.
  • the upper boundary surface of the floor limits the receiving space of the box downwards, while the side wall limits the receiving space in this position of the box to the sides, i.e. in horizontal directions.
  • the boundary surface is spanned from the top of the floor. This also applies if the floor is designed in a grid shape or the like.
  • the upper, in particular flat, boundary surface is the surface on which the objects stored in the box in the receiving space rest in the operating position.
  • the stacking direction is used as a reference direction in several places when defining the invention.
  • the mentioned upper, in particular flat, boundary surface of the floor could also be used as a geometric reference, in which case it would be assumed that the stacking direction forms a surface normal to this upper boundary surface of the floor, i.e. orthogonally on all sides on the upper boundary surface of the floor stands.
  • Boxes according to the invention can be open at the top, i.e. on the side of the side wall facing away from the floor. In other words, such boxes have a receiving space that is open at the top.
  • stackable boxes according to the invention can of course also be closed with a lid on the side of the receiving space opposite the floor by attaching a corresponding lid to this side of a side wall.
  • the first exemplary embodiment of the invention will be discussed below, which is shown in the Fig. 1 to 19 is shown. The following description of the further exemplary embodiments then focuses on the differences from the first exemplary embodiment.
  • the box 1 according to the invention of the first exemplary embodiment is in the Fig. 1 to 11 stacked in the stacking direction 2 on another box 1 according to the invention of the same type.
  • the Fig. 12-19 show this box 1 of the first exemplary embodiment individually or parts of it.
  • the box 1 has a base 3 and a side wall 4 which projects beyond the base 3 parallel to the stacking direction 2 and, in this exemplary embodiment, runs completely around the base 3.
  • the bottom 3 and the side wall 4 together delimit the receiving space 5 of the box 1, which is intended to hold the objects in the box.
  • the receiving space 5 is delimited downwards by an upper, here flat boundary surface 17 of the floor 3.
  • the stacking direction 2 forms a surface normal to this upper boundary surface 17 of the base 3. In other words, the stacking direction 2 runs normal to the upper boundary surface 17 of the base 3.
  • the stacking direction 2 is also predetermined in this exemplary embodiment in that the base is used to stack the boxes 1 on top of one another 3 of the upper box 1 must be inserted into the upper area of the receiving space 5 of the lower box 1 surrounded by the side wall 4. Like this, for example Fig. 2 can be clearly seen, this results in a positive connection in the direction orthogonal to the stacking direction 2. This means that the boxes 1 have to be placed on top of each other in the stacking direction 2 for stacking on top of each other and the upper box or Boxes 1 must be lifted off the lower box or boxes 1 against the stacking direction 2. As already explained at the beginning, both the bottom 3 and the side wall 4 can be designed as self-contained surfaces. This is not the case in this exemplary embodiment.
  • both the bottom 3 and the side walls 4 each have openings.
  • the floor 3 is formed by a lattice-shaped structure.
  • the side wall 4 has a large number of window-like openings. All of this is of course only shown as an example and can also be carried out in other ways known per se. Above all, reinforcing ribs and the like can also be formed both on the bottom 3 and on the side wall 4, to the extent necessary for the intended purpose.
  • the boxes 1 shown here have a rectangular basic shape with four corner regions 16, which in this exemplary embodiment are rounded. Side wall sections 21 run between the corner regions 16. In the embodiment variants shown here, the side wall 4, which runs completely around the base 3, is thus formed from the four corner regions 16 and the preferably straight side wall sections 21 running between them.
  • boxes 1 according to the invention with a basic shape that is not rectangular but with a different design are also conceivable and possible.
  • the preferred side wall sections 21 realized here are each designed to be straight or linear. They each meet an adjacent side wall section 21 at an orthogonal angle in the corner regions 16. Of course, this does not have to be the case either.
  • the number of corner regions 16 and the number and shape of the side wall sections 21 can of course also be designed differently.
  • the boxes 1 are designed with adapters arranged at a distance from one another for mechanical gripping of the box 1 by means of at least one gripping device 6.
  • the adapters are each designed in the side wall 4 as channels 8 extending longitudinally in a longitudinal direction 7 running parallel to the stacking direction 2, the channels 8 each having an inlet opening 9 and an outlet opening 10 and in between one delimited by a channel boundary wall 11 of the box 1 and in the respective longitudinal direction 7 have a longitudinally extending inner channel cavity 12 for passing the gripping device 6 through the inlet opening 9 and the inner channel cavity 12 and the outlet opening 10.
  • the channel boundary wall 11 is advantageously, as also implemented here, designed as a partial area of the side wall 4.
  • the channel boundary wall 11 delimits the channel inner cavity 12 in a closed circumference.
  • Circumferentially closed means that the channel boundary wall 11 surrounds the channel interior cavity 12 over a circumferential angle of 360°. This is good in relation to the first exemplary embodiment Fig. 3 , 4 , 9 , 12 to 14 and 15 to see.
  • the circumferentially closed design can also be seen in a sectional plane 13 normal to the stacking direction 2. Such sectional planes 13 are exemplified in Fig. 5 drawn.
  • the channels 8 are each formed in a corner region 16 of the side wall 4, as also shown in the first exemplary embodiment.
  • at least two channels 8 are advantageously formed in each box or its side wall 4.
  • Preferred embodiments provide that at least four, preferably exactly four, channels 8 are arranged in the side wall 4.
  • the channels 8 arranged in the side wall 4 or, in preferred embodiments, in the corner regions 16 serve to allow a corresponding gripping device 6 to be guided through them, so that the correspondingly designed gripping device 6 covers the inlet opening 9, the inner channel cavity 12 and the outlet opening 10 of the respective Channel 8 can penetrate.
  • the shape of the gripping device and the shape of the channel 8 should be coordinated with one another, with different shapes being fundamentally conceivable and possible.
  • the inner channel cavity 12 of the respective channel 8 has a circular cross section at least in sections, as is also the case in the first exemplary embodiment shown here.
  • the channel 8 preferably extends with its longitudinal extension direction 7 over the entire or at least a large part of the height extension 15 of the side wall 4 in the area of the respective channel 8 in a direction parallel to the stacking direction 2.
  • the side wall 4 in the area of the respective channel 8 has a height extension 15 in a direction parallel to the stacking direction 2 and the channel 8 extends over at least 50%, preferably over at least 80%, of this height extension 15 of the side wall 4.
  • the channel 8 in this first exemplary embodiment extends over practically the entire height extent 15 of the side wall 4. It is also advantageous if the longitudinal extent of the respective channel 8 in its longitudinal direction is at least, preferably twice, as large as the diameter of the inlet opening 9 or the outlet opening 10. If in doubt, the largest of these diameters should be used.
  • the, preferably at least two of the channels 8 of each of the boxes 1 are arranged in alignment with a channel 8 of the box 1 arranged below and/or above for the passage of a gripping device 6.

  • the oblique areas 24 of the respective top 22 of the side wall sections 21 of the lower box 1 are spaced from the respective undersides 23 of the side wall sections 21 of the box 1 stacked above Fig. 27
  • the clearly visible air gap in turn promotes the drying of the top and bottom sides of the side wall sections.
  • Fig. 28 you can see a section through the side wall sections 21 of the stacked boxes 1 in the area of the contact surfaces 27 formed on the respective undersides 23 of the side wall sections 21. The fact that these protrude over the areas 26 adjacent to them is clear Fig. 26 good to see.
  • the contact surfaces 27 are arranged in a first level 28 and the adjacent areas 26 of the undersides 23 of the respective underside 23 are arranged in a second level 29, the first level 28 and the second level 29 enclose an acute angle 30 with each other.
  • the first level 28 is again off Fig. 28 also in Fig. 27 registered.
  • This exemplary embodiment shows in particular in Fig.
  • 25 to 28 also shows, by way of example, that in the case in which the contact surfaces 27 projecting over the respective adjacent areas 26 of the underside 23 are formed on the underside 23, the areas 26 of the underside 23 adjacent to the contact areas 27 can run in a plane 33, on which the stacking direction 2 is arranged normally, see in particular Fig. 27 .
  • FIG. 29 shows analogously to Fig. 6
  • Fig. 27 shows analogously to Fig. 6
  • Fig. 6 again the situation in a section through the side walls 21 of the stacked boxes 1 outside the areas of the contact surfaces 25 and 27. In these areas there is again the spaced arrangement and thus the air gap that supports drying between the undersides 23 of the upper box 1 and the obliquely inclined areas 24 on the top sides 22 of the side wall sections 21 of the box 1 arranged underneath.
  • the angle 30 between the first level 28 and the second level 29 is as follows Fig. 29 shown, again the same as in the other two previously described exemplary embodiments.
  • the sizes of the contact surfaces 25 and 27 as well as their relationship to the remaining surfaces of the top sides 22 and bottom sides 23 of the side wall sections 21 can in principle be adjusted accordingly in accordance with the load requirements to be expected or to be achieved. However, it is favorable if a ratio between the sum of the areas of all contact surfaces 25 on the top sides 22 of all side wall sections 21 of the box 1 on the one hand and the total area of the top sides of the side wall 4 of the box 1 on the other hand is in a range of 1:5 to 1:15, preferably 1:9 to 1:11. The same applies advantageously if the contact surfaces 27 are arranged on the undersides 23 of the side walls 4.
  • a ratio between the sum of the areas of all contact surfaces 27 on the undersides 23 of all side wall sections 21 of the box 1 on the one hand and the total area of the undersides 23 of the side wall 4 of the box 1 on the other hand is in a range from 1:5 to 1: 15, preferably from 1:9 to 1:11.
  • the respective contact area 25 or 27 has an area in the range from 75 mm 2 to 175 mm 2 , preferably from 120 mm 2 to 135 mm 2 .
  • a ratio between the sum of the areas of all contact surfaces 25 or 27 on the top sides 22 and / or the bottom sides 23 of all side wall sections 21 of the box 1 on the one hand and the total area of the upper boundary surface 17 of the bottom 3 of the box 1 on the other hand is in a range from 1:100 to 1:130, preferably from 1:110 to 1:115.
