Abstract

The number of especially raw fish containers (1) are assembled to a stack in which they rotate to facilitate access. Liquid especially water from melting ice drains to the inner base (10) of the container. The base zone sidewalls (11, 12, 13, 14) of each container have drainage gullies which are open-topped for most of their length. The holes (51, 52, 53, 54) in the sidewall discharge to the outer face of the container, where the water drains directly in contact with the container outer wall into the outer water capture gully of the container below. Water continues to drain down the container stack outer face until it reaches the ground for capture in a suitable vessel or drain.

Description

The present invention relates to a rotary stacking container according to the preamble of claim 1.

A rotary stacking container of the type mentioned is out DE-U 295 09 562 known. Run with this container the liquid drainage ducts emanating from each footprint parallel to the longitudinal direction of the container in Form of a recessed groove with a small slope across by protruding outward the edge web of the concerned Sidewall to the very outside. That with stacked containers derived through these fluid drainage channels Water from the container above it then runs over the edge web and drips from it at a distance from the associated side wall approximately parallel down to this freely.

A disadvantage of this known container is considered that through the fluid drainage channels drained liquid freely falls down and then hits the floor and causes undesirable pollution the environment. It is also in many Cases also hygienically questionable if dripping water is out the containers, e.g. from fresh fish stored therein, in the environment is drained.

It is therefore the task of a rotary stacking container of the type mentioned at the beginning, which the avoids disadvantages listed and in particular a controlled discharge from the containers drained liquid without pollution of the environment is made possible.

This object is achieved in accordance with the invention by a rotary stacking container of the type mentioned, the is characterized in that the discharge channels over part of their length as upwardly open channels lengthways in the edge web of the side walls having the standing surfaces run and that at the end of each drainage channel at least one opening to the outer surface in the edge web the associated side wall is provided.

With the invention it is advantageously achieved that the liquid discharged through the discharge channels the passage through the opening at the end of each discharge channel on the outer surface of the associated side wall runs down. By between the liquid and the outer surface of the side wall naturally occurring Adhesive and attractive forces will drain freely the liquid prevented; instead the liquid along the outer surface of each Side wall of the container from top to bottom and then hits each of several stacked containers to the initial area of the drainage channel of the lower container to continue from there in the same way to pour down. At the bottom of a stack of containers can then collect the liquid if necessary or derived in an orderly manner.

It is also contemplated that the footprint of one Side wall at its ends in the corner area to the neighboring ones two side walls are arranged that the standing areas the other side wall relative to that of one Sidewall offset inwards towards each other and that the length of the trough-shaped part of the discharge channels corresponds to the offset of the stand space. If such rotary stacking containers are stacked, stand always two different side walls, usually the end walls, one above the other. With these different Sidewalls are also the openings to the outer surface for the passage of the liquid accordingly the stand space. This offset the Breakthroughs are shaped by the length of the gutter Part of the discharge channels in the longitudinal direction of the edge web balanced so that the outside on a container its side wall from top to bottom flowing liquid again and again in the initial area of the discharge channel of the container underneath. at a stack of several such rotary stacking containers places the liquid from the upper container to the lower a meandering flow path back, whereby the substantially horizontal flow path sections through the channel-shaped parts of the discharge channels and the substantially vertical flow path sections through the outer surface of the side walls are formed.

To the between the emerging from the opening down Liquid and the outer surface of the associated To increase side wall acting forces, it is proposed that below the openings on End of the drainage channels on the outer surface of the side walls extending vertically, projecting outwards Diverter ribs are arranged, each with an opening in the between two adjacent discharge ribs formed gap opens. The one flowing from top to bottom Liquid is essentially here between the two adjacent discharge ribs formed gap guided and so securely on the outer surface of the container side wall passed along without dripping from the Sidewall is possible.

A further development of the last described embodiment of the rotary stacking container provides that the discharge ribs viewed from top to bottom become wedge-shaped lower and only run over part of the height of the side wall. In this embodiment, the discharge ribs are open limits the area near the opening, since in the Practice only here there is a risk that the liquid immediately behind the opening from the side wall of the container drips freely. In the further course of the The discharge ribs are the flow path of the liquid downwards no longer absolutely necessary since here caused by a smooth outer surface of the side wall Forces on the liquid are sufficiently large.

A preferred embodiment of the rotary stacking container sees furthermore that that the stand areas Sidewalls with wavy or trapezoidal or rectangular bulges facing outwards are executed, with the lower end of the upper Container when stacking several containers on the Footprints of the lower container stands that the liquid discharge openings each in the inner corner between the bottom and the bulges are arranged and that the openings at the end of the drainage channels each lie on the bulges. This shape which allows the sidewalls with stand space the desired stacking and nesting of the containers and at the same time ensures stable side walls thin walls. The positioning described the liquid discharge openings and the openings ensures that both in side view of the container seen essentially in a vertical plane lie so that both the bottom out of the container liquid emerging from the liquid discharge openings as well as that of the opening along the outer surface liquid flowing down the side wall practically at the same point on the lower edge of the Side wall meet. Below that point the stack is exactly the beginning of the range of the liquid drainage channel below standing additional rotary stacking container.

On the one hand, particularly stable around the bottom of the container to make and on the other hand a derivative of itself liquid collecting on the floor to the liquid discharge openings to effect, it is provided that the Bottom with a seen in cross and longitudinal section above curved profile is executed.

An effective measure to increase strength and The load capacity of the rotary stacking container is that the edge web on its outer circumference one down has pointing edge strip and that in the horizontal Areas of the edge web several openings are arranged. The one in the horizontal areas The openings provided in the edge web serve in particular for draining washing liquid when the Rotary stacking container washed after use for cleaning becomes. Regardless of the position of the rotary stacking container after taking this washing process, the drain all washing liquid from the container, see above that a complete drying of the washed container is guaranteed without paying attention must, like the washed container to dry is positioned.

It is also provided that the downward-facing Edge web strips at least on two opposite one another Sidewalls a straight through smooth Have lower edge. With this design, the created an advantageous opportunity, the rotary stacking container hanging on a shelf, the two on top of each other Rails to be pointed, on which the lower edges the edge web strips of the rotary stacking container rest and when inserting it into the shelf and when removing it slide off the shelf without any particular resistance can. Such shelves for containers are in particular spread on ships to ensure safe and tip-free To ensure storage of the containers even at sea.

Another major advantage of the previously described Stack & nest container is that it is on very easily modified to a liquid collection container can be. All that is required is that the liquid drain holes in the bottom are closed and that at the end of the discharge channels instead of the openings to the outside of the associated Sidewall one passage to the inside of the associated side wall is arranged. As can be seen the changes required are very small and can be produced with little technical effort of the rotary stacking container. The modified rotary stacking container is because of the liquid discharge openings are locked in the ground, liquid-tight; also the liquid that flows through its drainage channels, not to the outside derived but inwards into the interior of the container guided. In this way the special is modified Rotary stacking container as a liquid collecting container usable, which is useful as a lower container in a stack of containers is arranged. For confusion with the previously described rotary stacking containers for the goods to be stored, e.g. Fresh fish, shrimp or the like, exclude the modified container, which as Liquid collection container is used, a different color preserved or by external markings, e.g. Color areas or stickers are marked.

To cost-effective mass production of the rotary stacking container to enable according to the invention and in order as possible low weight to achieve a high load capacity, it is preferably provided that the rotary stacking container as a one-piece injection molded part made of plastic is made.

As shown in Figures 1 and 2 of the drawing the rotary stack container shown as an embodiment 1 an essentially rectangular outline with a Bottom 10 and four side walls integrally connected to this 11, 12, 13, 14.

Figure 1 shows the left end wall 11 and left A portion of the long side walls above and below 13, 14. The figure shows a corresponding illustration 2 the right end wall 12 and above and below each also a section of the longitudinal side walls 13, 14. As a comparison of Figures 1 and 2 shows, are the longitudinal side walls 13, 14 are mirror-symmetrical to one another and executed identically, but not the two Front side walls 11 and 12. The from Figures 1 and 2 recognizable different design of the front side walls 11 and 12 optionally allows stacking or a nest, i.e. a nesting, more identical Rotary stacking container 1, depending on how the two containers 1 can be placed on top of each other. When the container 1 is placed on top of one another are that two identical end walls 11 on one side and 12 on the other side meet, the container 1 fit over one Part of their height into each other. In contrast, one of the containers rotated by 180 ° in the horizontal plane, then hits an end wall 11 of a container 1 on a for this purpose, different end wall 12 of the other container and vice versa. Fit in this condition the two containers 1 are not in each other, but stand each other. For this purpose, each container 1 on the Top of its end walls 11, 12 standing areas 21, 22 and 23, 24. On these stands 21 to 24 comes when stacking containers 1 an associated Stand area 21 ', 22' or 23 ', 24', the in Figures 1 and 2 indicated in dash-dotted lines is. To on the one hand the stand areas 21 to 24 create and on the other hand the nesting of two containers 1, the end walls 11, 12 with wall shafts or bulges 110, 120. In the left end wall shown in Figure 1 11 are these wall waves or bulges 110 outside in the immediate vicinity of the long side walls 13, 14; in contrast to it are the wall waves or bulges 120 in the visible in Figure 2 right end wall 12 from the long side walls 13, 14 attached spaced inward. The standing surfaces 21, 22 are at the end wall 11 seen in the longitudinal direction of the end wall 11 inside arranged by the wall shafts or bulges 110. The standing surfaces are at the right end wall 12 23, 24 each outside of the wall shafts or bulges 120 positioned. In the immediate vicinity of the stands 21 to 24 are centering bevels 31 to 34 provided when stacking several containers 1 facilitate correct positioning when touching down.

As far as described so far, corresponds to that shown Rotary stacking container 1 known rotary stacking containers.

It is essential in the rotary stacking container shown 1 that means for the targeted removal of liquids are provided from inside the container 1. There is always a need for draining liquids then when from the goods stored in container 1 with the Time liquids leak, which e.g. with ice-cold Fresh fish or other seafood the case is.

From Figures 1 and 2 it can be seen that each in the area of the wall shafts or bulges 110, 120 Liquid discharge openings 51, 52, 53, 54 are provided are. These discharge openings 51 to 54 are located each in the corner area between the floor 10 and the Front side wall 11, 12. These discharge openings 51 to 54 form a liquid-permeable flow path from the inside of the container 1 to the outside.

Furthermore, the means for draining liquids a plurality of liquid discharge channels 41, 42, 43, 44, each in the top of the end walls 11, 12 are provided. Around these fluid drainage channels To accommodate 41 to 44 and at the same time to make container 1 as stable as possible, are all side walls 11 to 14 with a horizontal, peripheral edge web 11 'to 14' formed on the then one each not visible in FIGS. 1 and 2 Edge web strip 11 '' to 14 '' which connects in Vertical direction points downwards.

The liquid discharge channels 41 to 44 each include two different channel areas: a first area runs in the longitudinal direction of the container, i.e. in the transverse direction of the end wall through the stands 21 to 24. A second, also upward, gutter-shaped Part 41 'to 44' then runs at right angles to each first channel region in the longitudinal direction of the end wall. The channel parts 41 ', 42' run in the left End wall 11 according to Figure 1 of the first channel areas outwards, while the channel areas 43 ', 44 'in the right front side wall 12 according to FIG. 2 from the first channel areas 43, 44 along the end wall 12 run inwards.

At the outer end of the channel parts 41 ', 42' of the left end wall 11, openings 141 ', 142' are provided, which penetrate the edge web 11 'and to the outside the front side wall 11 lead. In the right front wall 12 according to Figure 2 are each at the inner end the channel parts 43 ', 44' are provided with openings 143 ', 144', which pass through the edge web 12 'there and to Guide the outside of the end wall 12.

As by the dotted lines in the foot areas 21 'to 24' is indicated are with stacked containers 1 each the liquid discharge openings 51 up to 54 exactly above the liquid drainage channels 41 to 44 positioned. This ensures that from the each upper container 1 through its liquid discharge openings 51 to 54 draining liquid in each case in the associated liquid drainage channel 41 to 44 of the container 1 below. Flows from the liquid discharge channel 41 to 44 then the liquid through the channel-shaped channel part 41 'to 44' and by the attached at the end Openings 141 'to 144' to the outer surface the associated end wall 11 or 12. From there the drained liquid flows along the outer Surface of the end walls 11, 12 down and meets there if another container 1 is arranged there is again on one of the liquid drainage channels 41 to 44 of the lower container 1. Even with one Larger number of containers stacked one on top of the other 1 In this way, there is a targeted derivation from the containers 1 leaking liquid from top to bottom each along the liquid discharge channels 41 to 44, the Channel parts 41 'to 44' and the outer surface of the end walls 11, 12 without dripping and uncontrolled Drainage of the liquid can come.

To ensure the adhesion of the liquid to the outer surface of the End face walls 11, 12 to improve and to avoid any dripping of liquid from the end walls 11, 12 can be safely excluded, are below the edge webs 11 ', 12 'in each case in the area of the openings 141' to 144 ' Ableitrippen 241 'to 244' provided in the figures 1 and 2 are covered and therefore in dashed lines Lines are indicated.

Finally, Figures 1 and 2 are openings 130, 140 in the edge webs 13 ', 14' of the long side walls 13, 14 removable. These openings 130, 140 serve in particular to drain washing liquid to allow if the container 1 according to their Use to be cleaned with a washing liquid, the discharge of the washing liquid regardless of the position assumed of the container 1 guaranteed is.

Figures 3 and 4 of the drawing, the container 1 in Section along the lines III in Figure 1 and IV in Figure 2 show again illustrate the different Design of the end walls 11, 12. Each below in Figures 3 and 4, the bottom 10 can be seen, wherein is clearly visible here that the bottom 10 with a upward curvature is formed. This bulge ensures that liquid flows to the outside Edge region of the bottom 10 is derived from where it can then be discharged to the outside. From the floor 10 the long side walls extend to the left and right 13, 14 upwards. The upper end of the long side walls 13, 14 each form an edge web 13 ', 14' the downward-facing edge web strip 13 '', 14 ''. At the top in the edge webs 13 ', 14' is one of each Openings 130, 140 visible.

In the background in Figure 3 from the inside of the container visible front face wall 11 are the wall waves bulges or bulges 110 on the outside in the corner area the longitudinal side walls 13, 14. Above these wall waves or bulges 110 are the standing surfaces 21, 22 provided through which the liquid drainage channels 41, 42 with the channel-shaped channel parts 41 ', 42' run.

In the right part of Figure 3 to the right of the dash-dotted line longitudinal median plane 19 shown is the container 1 in terms of its liquid drainage means executed as before using FIGS. 1 and 2 described. On the outside, i.e. 3 right end according to FIG of the channel part 41 ', the openings 141' are provided, the outer surface facing away from the viewer the front side wall 11 lead. On both sides the openings 141 'are parallel to each other vertical fins 241 ' arranged on the outer surface not visible here the front side wall 11 and therefore only are shown in dashed lines.

At the bottom right in FIG. 3 are the liquid discharge openings 51 recognizable in the associated foot area 24 'of the container 1 and a discharge of liquid allow from the inside of the container 1 to the outside.

In contrast to the design described so far of the container 1 shows the left half of Figure 3 one Execution of the container 1, in which a liquid drain to the outside and the container 1 now a function as a liquid collection container Has. For this purpose, the end wall 11 is only in slightly modified in two areas. The first area relates to the outer end of the channel part 42 '; instead of the leading to the outer surface of the end wall 11 Openings 142 'here is a passage 342' for Provided inside the container 1. The second variation affects the lower left corner of the front wall 11 of the container 1, in which the original there existing liquid discharge openings 52 through a Closure 52 'are replaced. This closure 52 ' can also be made in one piece with the remaining material of the end wall 11 already executed in their manufacture his.

Figure 4 shows the opposite representation in the same manner Front side wall 12, being right in Figure 4 from the longitudinal median plane 19 also based on FIG 1 and 2 described embodiment of the container 1 with its means for draining liquid to the outside 19, while to the left of the longitudinal median plane 19 the container 1 in its design as a liquid collection container is shown. The two different ones Container designs are only for reasons of clarity each in a drawing figure summarized; are of course practical executed containers 1 always both end walls 12th either completely in the version with liquid drainage agents externally or entirely by means for collecting and introducing liquid into the Executed inside the container.

The end wall 12 is in the background of FIG. 4 recognizable with their wall waves or bulges 120. It is particularly clear here that the wall waves or bulges 120 spaced from the longitudinal side walls 13, 14 and shifted towards each other inwards the end wall 12 are arranged. At the bottom the wall shaft or bulge 120 in the right half the end wall 12 are those in the corner area to the floor 10 liquid discharge openings provided there 54 recognizable, below which the associated foot area 21 'lies.

The standing area 24 is shown at the top right in FIG. 4, through which the liquid discharge channel 44 with its channel part 44 '. At its inner end are the openings 144 'to the outer surface of the end wall 12 provided, here also discharge ribs 244 'are provided.

In contrast, the left half of FIG. 4 again at the inner end of the channel part 43 ' 343 'to the inside of the container 1 instead of the openings 143 'is provided. Also here is again, in analogy to Figure 3, the bottom left at the bottom of the wall shaft or bulge 120 is a liquid discharge opening 53 replaced by a closure 53 ' or simply the discharge opening 53 without replacement omitted.

With regard to the further reference numerals contained in FIG. 4 reference is made to the previous description.

FIG. 5 of the drawing shows the one on the left according to FIG Front side wall 11 of the container 1 in front view, i.e. seen from the outside. At the bottom is the bottom 10 of the container 1 visible, its left and right corner area form the foot areas 24 ', 23'. Immediately at this Foot areas 24 ', 23' are also the liquid discharge openings 51, 52 attached. So that's in figure 5 shown embodiment of the container 1 again with the means for draining off liquid Outside.

The longitudinal side walls lie on the left and right in FIG 13, 14, in the vicinity of which the wall waves or bulges 110 are located. The front wall is on the top 11 through the edge web 11 'with the downward pointing Edge web strip 11 '' limited. Clearly visible is here that the bottom edge 211 of the downward facing Edge strip 11 '' a continuous smooth and has a straight course. This straightforward design the lower edge 211 ensures that, in connection with an equally designed lower edge on the opposite end wall 12, the container 1 without any problems and with low sliding resistance Support rails formed shelf inserted and out of this can be removed. On such a shelf the container 1 "hangs" on its edge web strips 11 '', 12 '', which prevents tipping. Therefore such shelves are preferably used on fishing vessels.

In each case in the upper part of the wall waves or bulges 110, partly through the edge web strip 11 " covered, the discharge ribs 241 ', 242' can be seen. By Flow arrows 9 is the flow path from derived Liquid indicated by one in Figure 5 not drawn upper container 1 between the discharge ribs 241 ', 242' down and then continue along the Outer surface of the end wall 11 flows.

Finally, FIG. 5 shows two pairs of support ribs 111, which are relative to the discharge ribs 241 ', 242 'on the front side wall 11 arranged inwards are and also partly through the edge strip 11 '' are covered. The mounting ribs 111 extend down slightly further than the discharge ribs 241 ', 242' and are used in nested empty containers 1 these against mutual jamming secure and a defined nest distance too guarantee.

In the same representation as the figure 5 shows finally, FIG. 6 shows the right side wall according to FIG. 2 12 of the container 1 also in front view from the outside. As already explained with reference to FIG. 2 and FIG. 4, are the wall waves in this end wall 12 or bulges 120 within the end wall 12 offset inwards. Down in the wall waves or bulges 120 are the liquid discharge openings 53, 54 in the immediate vicinity of the there foot areas 21 ', 22' attached. At the top of the Wall waves or bulges 120 are the discharge ribs 243 ', 244' visible, with the derived one also here Liquid according to the flow arrows 9 between flows down the discharge ribs 243 ', 244'.

So to speak, in exchange with the discharge ribs 243 ', 244' at the front side wall 12 the offset ribs 121 now offset outside. Their function corresponds to that of Support ribs 111 on the other end wall 11.

The front wall 12 is again upwards here through the edge web 12 'with its outside, after border strip 12 '' below. The Lower edge 212 of the downward-facing edge strip 12 '' is also here with a straight through run smoothly in conjunction with the Edge web strips 11 ″ of the opposite one already described above End wall 11 hanging the container 1 in a shelf of the type mentioned.

In addition, at the four corners of the web strips 11 "to 14 '' still ribs or material reinforcements be provided to the edge web strips 11 '' to 14 " when inserting containers 1 into those described above, Shelves with mounting rails against damage to protect.

As can be seen from the above description, can the container 1 in a simple manner in two different Designs are made, namely on the one hand as a container with means for draining liquids to the outside and on the other hand as a liquid collection container. In practice, the procedure is appropriately that with a stack of several containers each the lower container is a liquid collection container, while the containers stacked on top of it with the means for draining liquids to the outside are executed and in which goods to be stored, then Secrete liquids, are housed.
