Definitions
- the invention relates to a plastic container with a tread.
- plastic containers with a tread are known from the prior art. Such a plastic container is for example in the DE 10 2013 207 943 B4 described.
- DE 203 15 302 U1 discloses a container made of plastic, in particular a storage and transport box, made in one piece by welding, which is provided on the lower surface of its base with ribs which form a base center panel, and which has flat webs providing an outer running rim all around the bottom edge as a double bottom, characterized in that the flat webs are designed as smooth frame plates (9) and have a circumferential outer rib (10) and a circumferential inner rib (11) of the base (2) are welded.
- DE 198 44 014 C1 discloses a transport box made in one piece from plastic with a flat floor in the middle area of the box, under which there are at least two parallel runners in the edge area of the box, which are connected to the floor by ribs running transversely to the runners, in which the runners, the transverse ribs and the bottom surface are formed outwardly and / or inwardly open pockets, and in which the runners on the side facing the box center have a longitudinal section which is directed upwards.
- DE 199 17 114 A1 discloses a box-shaped, a data memory having container or the like made of plastic, in particular a storage and transport box, with a bottom which is stabilized on its underside with stiffening ribs, which in the area of the bottom edge carry a circumferential tread formed by flat webs, which together with the Bottom and two spaced-apart stiffening ribs extending transversely to the bottom edge delimit free spaces, which are designed as pockets open on the bottom edge or on the inside of the running ring or passages open on both sides.
- DE 299 08 668 U1 discloses a box-shaped container made of plastic, in particular a storage and transport box, with a bottom which is stabilized on its underside with stiffening ribs, which in the area of the bottom edge carry a circumferential tread formed by flat webs, which together with the bottom and two in each case Distance between adjacent stiffening ribs extending transversely to the bottom edge delimits free spaces, which are designed as pockets that are open on the bottom edge side or on the inside of the running ring or passages open on both sides are, wherein the tread is formed on the inner edges of its flat webs with a stepped profile.
- the object of the invention is to improve this plastic container.
- the object on which the invention is based is achieved by the features of the independent patent claim.
- Preferred embodiments of the invention are specified in the dependent claims.
- a plastic container is specified with a base and side walls standing on the base, a receiving area of the container being defined by the base and the side walls.
- the bottom forms a plane on its side facing away from the receiving region, the plane bearing an inner region, a tread surrounding the inner region and first ribs protruding from the plane.
- the tread has a running surface for the container and the running surface is raised in relation to the inner area in the direction perpendicular to the plane.
- Each of the first ribs extends from the inner region in the direction of the tread, with the end face of the first rib pointing in the direction of extension opening tangentially into the plane with respect to each of the first ribs, the end face having a concave shape and the plane overlapping in an overlapping region, wherein the overlap area lies between the inner area and the tread.
- running surface is understood to mean that surface of the container on which the container rests at least partially on a floor surface. He preferably stands on a floor surface exclusively with the tread.
- the running surface is the surface with which the plastic container runs onto the rollers of the roller conveyor and then comes into contact with the transport rollers of the roller conveyor.
- Embodiments of the invention could have the advantage that the load-bearing capacity of the plastic container for transported goods in its receiving area is thereby increased is that the first specially shaped ribs are now also provided. Due to the tangential opening of the first rib into the plane, forces acting on the plane are absorbed by the rib without force peaks, whereby the bottom of the plastic container is stabilized overall.
- tangentially opens into a plane is generally understood to mean that at the point of contact of the face with the plane, the slope of the face deviates by a maximum of 10 ° (preferably ⁇ 5 °) from the slope of the plane at this point. So if one assumes that the plane runs horizontally, the end face opens into the plane at an angle ⁇ 10 °, preferably ⁇ 5 °.
- the end face has a concave arc shape. This means that the surface of the end face is curved inwards, that is to say in a direction opposite to the direction of extension. Due to the concave arc shape, the forces acting on the rib could also be absorbed in a particularly uniform manner, so that here too the risk of the presence of force peaks in the rib and thus a possible risk of breakage of the rib is minimized.
- the end face at least partially overlaps the plane.
- the plastic container further comprises an inner rim surrounding the inner region, the inner rim directly adjoining the running rim and the running surface being raised in relation to the outer surface of the inner rim facing away from the receiving region in the direction perpendicular to the plane.
- the end face opens tangentially into the inner surface of the inner ring facing the receiving area. Due to the presence of the inner ring, it can also absorb and distribute the forces acting on the ground, with the same principles of force distribution due to the special shape of the inner ring with respect to the plane of the inner ring Front side of the first rib is given. The forces acting on the ground are absorbed by the first rib free of force peaks and are then in turn transferred to the inner rim, among other things, free of force peaks.
- the running surface is preferably rounded on its sides facing the inside and / or outward towards the walls in the direction of receiving the container, whereby the running surface can run onto a transport roller not abruptly, but steadily, evenly and gently.
- the second ribs can also carry the inner ring described above and an outer ring, which will also be the subject of the description.
- the first ribs are primarily responsible for the dissipation of forces which act from the receiving area from above the inner area and possibly also from above the inner rim through the transported goods on the floor. All other forces, especially those that act from the receiving area from above the tread, can be transmitted directly from the second ribs to the tread and from there to the surface on which the tread rests, for example the transport rollers.
- the inner area has a crown in the direction of the receiving area.
- Providing a crown could have the advantage that the floor above the inner area can bend within certain limits when the floor is heavily loaded by the transported goods, and it is nevertheless ensured that the container still rests exclusively on the tread on its tread .
- the container bottom can therefore bend a little downwards in the direction of the interior without the interior immediately coming into contact with the surface on which the plastic container rests with its running surface.
- the inner region has third ribs, the third ribs protruding from the plane and being supported, and the surfaces of the third ribs facing away from the receiving region having the crown.
- the plastic container further comprises an outer rim surrounding the running surface, the outer rim directly adjoining the running rim and the running surface being raised in relation to the outer surface of the outer rim facing away from the receiving area in the direction perpendicular to the plane.
- this could have the advantage that, due to the protruding tread between the inner and outer treads, it is possible to gently run onto the tread, so that the corresponding noise development is minimized when the plastic container in particular rolls over a roller conveyor.
- the transition between the inner rim and the running rim or the outer rim and the running rim should preferably not be abrupt, but should be designed so steadily and uniformly that the running rim gently runs onto the rollers.
- all of the first ribs are connected to one another on their side opposite the end face via a continuous wall projecting and supported from the plane, the wall delimiting the interior area.
- This could have the advantage of being very uneven Loading of the container bottom by the transported goods ensures a high rigidity of the bottom and the resulting forces, which act on a limited area of the bottom in particular with one-sided load on the bottom, are distributed over several of the first ribs.
- the second and third ribs could also be arranged on the wall, preferably cohesively.
- the wall carries the inner rim. This could also contribute to a positive distribution of forces.
- the wall is inclined outwardly pointing away from the inner area. This means that from the base points of the wall at which the wall joins the plane, the wall is inclined outwards, pointing away from the interior. This in turn could have the advantage that forces acting in the interior due to a central floor load on the container are efficiently directed in the direction of the running ring while avoiding force peaks. Overall, this could contribute to the stabilization of the container and thus improve the load-bearing capacity of the container with heavy transport goods.
- the Figure 1 shows a plastic container 100 with a base and side walls 102 standing on the base.
- the base and the side walls 102 define a receiving area 104 of the container in which goods to be transported can be received.
- the container 100 On the side of the bottom facing away from the receiving area 104, the container 100 has an inner area 106 which is provided with ribs.
- An inner rim 108 surrounds the inner region 106 and a running rim 110 surrounds the inner rim 108.
- a further outer rim 112 is also present, which surrounds the running rim 110.
- the running ring 110 is slightly raised compared to the inner ring 108 and the outer ring 112. In addition, it is increased compared to the inner area 106, so that when the container runs over a transport surface, for example over transport rollers or balls, only the container 100 comes into contact with the transport surface or the transport rollers (balls) via the running surface of the tread 110.
- various ribs are provided.
- FIG. 3 is another perspective view of the FIG Figure 1 shown container, the inner rim 108, the running rim 110 and the outer rim 112 have been removed in the drawing for the sake of simplicity.
- the result is now besides Ribs 202 of the inner region 106, further ribs 204 and further ribs 200 (seen incompletely in the direction perpendicular to the plane 206) can be seen.
- the bottom of the container 100 forms, on its side facing away from the receiving area 104, a plane 206 which carries all the ribs that can be seen.
- the inner region 106 or its ribs 202 are enclosed by means of a continuous wall 208, the ribs 204 adjoining this wall 208 and being materially connected to the wall 208.
- the plastic container 100 is preferably produced in one piece from a single material, for example by a corresponding injection molding process.
- the ribs 200 which stand up on the plane 206 and are supported by this plane 206, in turn carry both the running surface 110 and the outer running ring 112.
- the much shorter ribs 204 arranged between the ribs 200 on the other hand, only carry the inner ring 108, with the inner rim 108 can also be supported by the ribs 200.
- FIG. 11 shows a schematic cross-sectional view through the container 100, it being assumed here for the sake of simplicity that the ribs each run at right angles to the walls 102.
- the ribs 202 of the inner area 106 have a so-called crowning, which means that there is a curvature in the direction of the receiving area, so that the container bottom in the inner area 106 can bend downwards under heavy loads without the ribs coming into contact with that surface come on which the container 100 stands up.
- the inner region 106 is surrounded by the wall 208, in the example the Figure 3 here too, for the sake of simplicity, the wall 208 is not inclined, but rather stands perpendicular to the plane. However, it is possible that the wall 208 is inclined outward, that is to say in each case in the direction 304 starting from the base point to the wall between plane 206 and wall 208. Corresponding forces acting on the plane 206 are efficiently conducted from the inner region 106 in the direction of the running surface 110.
- the ribs 204 each extend in the direction 304, that is, starting from the inner region 106 in the direction of the tread 110.
- the end faces 308 of the ribs 204 open tangentially into the plane 206 both at the points 302 and (optionally) at the points 300 into the inside of the inner rim 108. Due to this "gentle" transition of the end faces 308 of the ribs 204 into the plane 206 or the inner rim 108, force peaks are avoided at the transition points 300 and 302, so that a possible risk of breakage at these points in heavy can be minimized in the receiving area 104 loads.
- the ribs 204 also have a concave shape, so that the end faces 308 of the ribs partially overlap the plane 206.
- the overlap area is exemplified in Figure 3 outlined with reference numeral 306.
- the end faces of the ribs 204 have a C-shape.
- the ribs 200 transmit the forces acting on the plane 206 to the running ring 110.
- the geometry shown enable that even when large loads are present in the receiving area 104, the container 100 should be able to slide quietly on the running surface 110, for example over a roller conveyor.
- FIG. 11 shows a perspective view of the container of FIG Figure 1 , whereby the running ring, the inner ring and the outer ring are again removed were. The same applies to the detailed view of the Figure 5 .
- the parts of the ribs directly adjacent to the inner ring, the running ring or the outer ring are also omitted.
- the geometric shape of the ribs 204 is a mirror image of the geometric shape of the ribs 204 at point 302, which in particular in FIG Figure 4 is clearly visible.

Description
Die Erfindung betrifft einen Kunststoffbehälter mit Laufkranz.The invention relates to a plastic container with a tread.
Aus dem Stand der Technik sind verschiedene Kunststoffbehälter mit Laufkranz bekannt. Ein solcher Kunststoffbehälter ist z.B. in der
Der Erfindung liegt die Aufgabe zugrunde, diesen Kunststoffbehälter zu verbessern. Die der Erfindung zugrundeliegende Aufgabe wird durch die Merkmale des unabhängigen Patentanspruchs gelöst. Bevorzugte Ausführungsformen der Erfindung sind in den abhängigen Patentansprüchen angegeben.The object of the invention is to improve this plastic container. The object on which the invention is based is achieved by the features of the independent patent claim. Preferred embodiments of the invention are specified in the dependent claims.
Es wird ein Kunststoffbehälter angegeben mit einem Boden und auf dem Boden stehenden Seitenwänden, wobei durch den Boden und die Seitenwände ein Aufnahmebereich des Behälters definiert. Der Boden bildet auf seiner dem Aufnahmebereich abgewandten Seite eine Ebene, wobei die Ebene einen Innenbereich, einen den Innenbereich umgebenden Laufkranz und von der Ebene abstehende erste Rippen trägt. Der Laufkranz weist eine Lauffläche für den Behälter auf und die Lauffläche ist gegenüber dem Innenbereich in Richtung senkrecht zur Ebene erhöht. Jede der ersten Rippen erstreckt sich ausgehend vom Innenbereich in Richtung des Laufkranzes, wobei bezüglich jeder der ersten Rippen die in die Erstreckungsrichtung weisende Stirnseite der ersten Rippe tangential in die Ebene mündet, wobei die Stirnseite eine konkave Form aufweist und die Ebene in einem Überlappungsbereich überlappt, wobei der Überlappungsbereich zwischen dem Innenbereich und dem Laufkranz liegt.A plastic container is specified with a base and side walls standing on the base, a receiving area of the container being defined by the base and the side walls. The bottom forms a plane on its side facing away from the receiving region, the plane bearing an inner region, a tread surrounding the inner region and first ribs protruding from the plane. The tread has a running surface for the container and the running surface is raised in relation to the inner area in the direction perpendicular to the plane. Each of the first ribs extends from the inner region in the direction of the tread, with the end face of the first rib pointing in the direction of extension opening tangentially into the plane with respect to each of the first ribs, the end face having a concave shape and the plane overlapping in an overlapping region, wherein the overlap area lies between the inner area and the tread.
Im Rahmen der vorliegenden Beschreibung wird als "Lauffläche" jene Fläche des Behälters verstanden, auf welcher der Behälter zumindest teilweise auf einer Bodenfläche aufsteht. Vorzugsweise steht er ausschließlich mit der Lauffläche auf einer Bodenfläche auf. Beim Rollen über eine Rollenbahn ist die Lauffläche jene Fläche, mit welcher der Kunststoffbehälter auf die Rollen der Rollenbahn aufläuft und dann mit den Transportrollen der Rollenbahn in Berührung gerät. Durch die Erhöhung der Lauffläche wird die Kontaktfläche minimiert, mit welcher der Behälter mit den Rollen der Rollenbahn in Berührung steht, wodurch insgesamt die Geräuschentwicklung beim Gleiten des Kunststoffbehälters über die Rollen der Rollenbahn minimiert werden kann.In the context of the present description, “running surface” is understood to mean that surface of the container on which the container rests at least partially on a floor surface. He preferably stands on a floor surface exclusively with the tread. When rolling over a roller conveyor, the running surface is the surface with which the plastic container runs onto the rollers of the roller conveyor and then comes into contact with the transport rollers of the roller conveyor. By increasing the running surface, the contact surface with which the container is in contact with the rollers of the roller conveyor is minimized, whereby overall the development of noise when the plastic container glides over the rollers of the roller conveyor can be minimized.
Ausführungsformen der Erfindung könnten den Vorteil haben, dass die Tragfähigkeit des Kunststoffbehälters von Transportgut in seinem Aufnahmebereich dadurch erhöht wird, dass zusätzlich nun die ersten speziell ausgeformten Rippen vorgesehen sind. Durch das tangentiale Münden der ersten Rippe in die Ebene werden durch das Transportgut auf die Ebene wirkenden Kräfte ohne Kraftspitzen von der Rippe aufgenommen, wodurch insgesamt der Boden des Kunststoffbehälters stabilisiert wird.Embodiments of the invention could have the advantage that the load-bearing capacity of the plastic container for transported goods in its receiving area is thereby increased is that the first specially shaped ribs are now also provided. Due to the tangential opening of the first rib into the plane, forces acting on the plane are absorbed by the rib without force peaks, whereby the bottom of the plastic container is stabilized overall.
Es sei angemerkt, dass unter "tangential in eine Ebene mündet" allgemein verstanden wird, dass am Berührungspunkt der Stirnseite mit der Ebene die Steigung der Stirnseite um maximal 10° (bevorzugt < 5°) von der Steigung der Ebene in diesem Punkt abweicht. Geht man also davon aus, dass die Ebene in der Horizontalen verläuft, so mündet die Stirnseite in die Ebene unter einem Winkel < 10°, bevorzugt < 5°.It should be noted that “tangentially opens into a plane” is generally understood to mean that at the point of contact of the face with the plane, the slope of the face deviates by a maximum of 10 ° (preferably <5 °) from the slope of the plane at this point. So if one assumes that the plane runs horizontally, the end face opens into the plane at an angle <10 °, preferably <5 °.
Nach einer Ausführungsform der Erfindung weist die Stirnseite eine konkave Bogenform auf. Dies bedeutet, dass also die Fläche der Stirnseite nach innen gewölbt ist, das heißt in eine Richtung entgegen der Erstreckungsrichtung. Aufgrund der konkaven Bogenform könnten auch die auf die Rippe wirkenden Kräfte in besonders gleichmäßiger Weise aufgenommen werden, sodass auch hier das Risiko des Vorhandenseins von Kraftspitzen in der Rippe und damit eine etwaige Bruchgefahr der Rippe minimiert wird.According to one embodiment of the invention, the end face has a concave arc shape. This means that the surface of the end face is curved inwards, that is to say in a direction opposite to the direction of extension. Due to the concave arc shape, the forces acting on the rib could also be absorbed in a particularly uniform manner, so that here too the risk of the presence of force peaks in the rib and thus a possible risk of breakage of the rib is minimized.
Zum Beispiel überlappt die Stirnseite die Ebene zumindest teilweise.For example, the end face at least partially overlaps the plane.
Nach einer Ausführungsform umfasst der Kunststoffbehälter ferner einen den Innenbereich umgebenden inneren Kranz, wobei der innere Kranz an den Laufkranz unmittelbar angrenzt und die Lauffläche gegenüber der von dem Aufnahmebereich abgewandten äußeren Oberfläche des inneren Kranzes in Richtung senkrecht zur Ebene erhöht ist. Dabei mündet die Stirnseite tangential in die der dem Aufnahmebereich zugewandten inneren Oberfläche des inneren Kranzes. Aufgrund des Vorhandenseins des inneren Kranzes kann auch dieser die auf den Boden wirkenden Kräfte aufnehmen und verteilen, wobei bezüglich der Ebene des inneren Kranzes dieselben Prinzipien der Kraftverteilung aufgrund der besonderen Ausformung der Stirnseite der ersten Rippe gegeben ist. Die auf den Boden wirkenden Kräfte werden frei von Kraftspitzen von der ersten Rippe aufgenommen und dann wiederum frei von Kraftspitzen unter anderem auf den inneren Kranz übertragen.According to one embodiment, the plastic container further comprises an inner rim surrounding the inner region, the inner rim directly adjoining the running rim and the running surface being raised in relation to the outer surface of the inner rim facing away from the receiving region in the direction perpendicular to the plane. The end face opens tangentially into the inner surface of the inner ring facing the receiving area. Due to the presence of the inner ring, it can also absorb and distribute the forces acting on the ground, with the same principles of force distribution due to the special shape of the inner ring with respect to the plane of the inner ring Front side of the first rib is given. The forces acting on the ground are absorbed by the first rib free of force peaks and are then in turn transferred to the inner rim, among other things, free of force peaks.
Vorzugsweise ist die Lauffläche an ihrer zur Innenseite und/oder nach außen zu den Wänden hin zugewandten Seiten in Richtung zur Aufnahme des Behälters hin abgerundet, wodurch die Lauffläche nicht abrupt, sondern stetig, gleichmäßig und sanft auf eine Transportrolle auflaufen kann.The running surface is preferably rounded on its sides facing the inside and / or outward towards the walls in the direction of receiving the container, whereby the running surface can run onto a transport roller not abruptly, but steadily, evenly and gently.
Nach einer Ausführungsform der Erfindung umfasst der Kunststoffbehälter ferner von der Ebene abstehende und getragene zweite Rippen, wobei
- die zweiten Rippen den Laufkranz tragen,
- sich die zweiten Rippen ausgehend vom Innenbereich in Richtung des Laufkranzes erstrecken und
- die ersten Rippen zwischen den zweiten Rippen aufgenommen sind.
- the second ribs carry the tread,
- the second ribs, starting from the inner region, extend in the direction of the tread and
- the first ribs are received between the second ribs.
Neben dem Laufkranz können die zweiten Rippen auch noch den obig beschriebenen inneren Kranz sowie einen äußeren Kranz tragen, der ebenfalls noch Gegenstand der Beschreibung sein wird.In addition to the running ring, the second ribs can also carry the inner ring described above and an outer ring, which will also be the subject of the description.
Insbesondere wenn die ersten Rippen ausschließlich den inneren Kranz tragen und also zu kurz sind, um in Berührung mit dem Laufkranz bzw. dem äußeren Kranz zu gelangen, könnte dies den Vorteil einer Gewichtsersparnis für den Kunststoffbehälter bedeuten. Die ersten Rippen sind in diesem Fall vornehmlich für die Ableitung von Kräften zuständig, welche vom Aufnahmebereich von oberhalb des Innenbereichs und gegebenenfalls noch von oberhalb des inneren Kranzes durch das Transportgut auf dem Boden wirken. Alle übrigen Kräfte, insbesondere solche, welche vom Aufnahmebereich von oberhalb des Laufkranzes wirken, können direkt von den zweiten Rippen auf den Laufkranz und von dort auf die Fläche übertragen werden, auf welcher der Laufkranz aufsteht, beispielsweise den Transportrollen.In particular, if the first ribs only carry the inner rim and are therefore too short to come into contact with the running rim or the outer rim, this could mean the advantage of a weight saving for the plastic container. In this case, the first ribs are primarily responsible for the dissipation of forces which act from the receiving area from above the inner area and possibly also from above the inner rim through the transported goods on the floor. All other forces, especially those that act from the receiving area from above the tread, can be transmitted directly from the second ribs to the tread and from there to the surface on which the tread rests, for example the transport rollers.
Nach einer weiteren Ausführungsform der Erfindung weist der Innenbereich eine Bombierung in Richtung zum Aufnahmebereich auf. Das Vorsehen einer Bombierung könnte den Vorteil haben, dass sich ein durchbiegen des Bodens oberhalb des Innenbereichs bei hoher Belastung des Bodens durch das Transportgut in gewissen Grenzen möglich ist und dennoch gewährleistet ist, dass nach wie vor der Behälter ausschließlich auf dem Laufkranz auf seiner Lauffläche aufsteht. Durch die Bombierung kann sich also der Behälterboden ein wenig nach unten in Richtung Innenbereich durchbiegen, ohne dass gleich der Innenbereich mit der Fläche in Berührung gerät, auf welcher der Kunststoffbehälter mit seiner Lauffläche aufsteht.According to a further embodiment of the invention, the inner area has a crown in the direction of the receiving area. Providing a crown could have the advantage that the floor above the inner area can bend within certain limits when the floor is heavily loaded by the transported goods, and it is nevertheless ensured that the container still rests exclusively on the tread on its tread . As a result of the crowning, the container bottom can therefore bend a little downwards in the direction of the interior without the interior immediately coming into contact with the surface on which the plastic container rests with its running surface.
Nach einer Ausführungsform der Erfindung weist der Innenbereich dritte Rippen auf, wobei die dritten Rippen von der Ebene abstehen und getragen werden und wobei die vom Aufnahmebereich wegweisenden Oberflächen der dritten Rippen die Bombierung aufweisen.According to one embodiment of the invention, the inner region has third ribs, the third ribs protruding from the plane and being supported, and the surfaces of the third ribs facing away from the receiving region having the crown.
Nach einer Ausführungsform der Erfindung umfasst der Kunststoffbehälter ferner einen die Lauffläche umgebenden äußeren Kranz, wobei der äußere Kranz an den Laufkranz unmittelbar angrenzt und die Lauffläche gegenüber der von dem Aufnahmebereich abgewandten äußeren Oberfläche des äußeren Kranzes in Richtung senkrecht zur Ebene erhöht ist. Wie bereits oben erwähnt könnte dies den Vorteil haben, dass aufgrund des Herausstehens des Laufkranzes zwischen dem inneren und dem äußeren Kranz ein sanftes Auflaufen auf den Laufkranz möglich ist, sodass beim insbesondere Rollen des Kunststoffbehälters über eine Rollenbahn die entsprechende Geräuschentwicklung minimiert wird. Der Übergang zwischen innerem Kranz und Laufkranz bzw. äußerem Kranz und Laufkranz sollte dabei vorzugsweise nicht abrupt, sondern so stetig gleichmäßig gestaltet sein, dass ein sanftes Auflaufen des Laufkranzes auf die Rollen gewährleistet ist.According to one embodiment of the invention, the plastic container further comprises an outer rim surrounding the running surface, the outer rim directly adjoining the running rim and the running surface being raised in relation to the outer surface of the outer rim facing away from the receiving area in the direction perpendicular to the plane. As already mentioned above, this could have the advantage that, due to the protruding tread between the inner and outer treads, it is possible to gently run onto the tread, so that the corresponding noise development is minimized when the plastic container in particular rolls over a roller conveyor. The transition between the inner rim and the running rim or the outer rim and the running rim should preferably not be abrupt, but should be designed so steadily and uniformly that the running rim gently runs onto the rollers.
Nach einer Ausführungsform der Erfindung sind alle ersten Rippen auf ihrer der Stirnseite gegenüberliegenden Seite über eine von der Ebene abstehende und getragene durchgängige Wand miteinander verbunden, wobei die Wand den Innenbereich begrenzt. Dies könnte den Vorteil haben, dass selbst bei sehr ungleichmäßiger Belastung des Behälterbodens durch das Transportgut eine hohe Steifigkeit des Bodens gewährleistet ist und die resultierenden Kräfte, welche bei insbesondere einseitiger Bodenbelastung auf einen beschränkten Bereich des Bodens wirken, gegenüber mehreren der ersten Rippen verteilt werden. An der Wand könnten aus demselben Grund auch die zweiten und dritten Rippen vorzugsweise stoffschlüssig angeordnet sein.According to one embodiment of the invention, all of the first ribs are connected to one another on their side opposite the end face via a continuous wall projecting and supported from the plane, the wall delimiting the interior area. This could have the advantage of being very uneven Loading of the container bottom by the transported goods ensures a high rigidity of the bottom and the resulting forces, which act on a limited area of the bottom in particular with one-sided load on the bottom, are distributed over several of the first ribs. For the same reason, the second and third ribs could also be arranged on the wall, preferably cohesively.
Nach einer Ausführungsform der Erfindung trägt die Wand den inneren Kranz. Auch dies könnte zu einer positiven Kräfteverteilung beitragen.According to one embodiment of the invention, the wall carries the inner rim. This could also contribute to a positive distribution of forces.
Nach einer weiteren Ausführungsform der Erfindung ist die Wand nach außen vom Innenbereich wegweisend geneigt. Das bedeutet, dass von den Fußpunkten der Wand, an welchen die Wand in die Ebene mündet, die Wand nach außen vom Innenbereich wegweisend geneigt ist. Dies wiederum könnte den Vorteil haben, dass insbesondere im Innenbereich aufgrund einer zentralen Bodenbelastung des Behälters wirkende Kräfte effizient unter Vermeidung von Kraftspitzen gezielt in Richtung des Laufkranzes geleitet werden. Dies könnte insgesamt zur Stabilisierung des Behälters beitragen und damit die Belastbarkeit des Behälters mit schwerem Transportgut verbessern.According to a further embodiment of the invention, the wall is inclined outwardly pointing away from the inner area. This means that from the base points of the wall at which the wall joins the plane, the wall is inclined outwards, pointing away from the interior. This in turn could have the advantage that forces acting in the interior due to a central floor load on the container are efficiently directed in the direction of the running ring while avoiding force peaks. Overall, this could contribute to the stabilization of the container and thus improve the load-bearing capacity of the container with heavy transport goods.
Es versteht sich, dass die obig beschriebenen Ausführungsformen in beliebiger Weise miteinander kombiniert werden können, solange sich die Kombinationen nicht gegenseitig ausschließen.It goes without saying that the embodiments described above can be combined with one another in any desired manner, as long as the combinations are not mutually exclusive.

Die Stirnseiten 308 der Rippen 204 münden dabei sowohl an den Stellen 302 tangential in die Ebene 206, als auch (optional) an den Stellen 300 in die Innenseite des inneren Kranzes 108. Aufgrund dieses "sanften" Übergehens der Stirnseiten 308 der Rippen 204 in die Ebene 206 bzw. den inneren Kranz 108 werden an den Übergangsstellen 300 bzw. 302 Kraftspitzen vermieden, sodass eine etwaige Bruchgefahr an diesen Stellen bei schweren im Aufnahmebereich 104 aufgenommenen Lasten minimiert werden kann.The
