An example of a single-piece plastic pallet is described in US-A-3.636.888 to Angelbeck. An example of a two-piece large-piece pallet in which two parts are connected by vibration welding is described in FR-A-2.387.850. Another approach is to create a series of differently shaped connected parts that are assembled to form pallets of different sizes from small to very large. One such pallet that combines a single unit of parts is described in US-A-3.636.888 to Angelbeck.

Each of these drawn descriptions of pallets poses one or more problems. The first four drawn examples consist of very large parts, the spraying of which is costly and time-consuming for the manufacturer. Due to their dimensions they are very bulky and difficult to transport even in assembled condition. A pallet manufactured according to the description of the second German disclosure letter mentioned is very labor intensive in the assembly, since the individual parts have to be screwed together. The pallet of the last drawn description is not suitable, since the individual parts connecting them are not assemblable, which means that the pallet can be lifted by only two seals, otherwise it would fall apart during the lifting.

DE-A-2 365 344 is known as a plastic pallet with a groove formation, whereby at the bottom of the grooves a depression or groove is formed along the groove, through which packing or fastening bands can be drawn, which can be placed around the goods after loading the pallet.

FR-A-2 140 093 is a stackable container with nut holes through which packing or fastening tape can be drawn.

The purpose of the invention is to create a plastic container and pallet system where the individual container is resistant to deformation even under thermal stress, has a permanent connection between the components, is easily stackable and cheaply manufactured, and one or more containers can be assembled into a unit, if necessary in conjunction with a specially designed pallet.

This task is solved by the characteristics described in claim 1.

This training of the container allows the combination of containers into a complex and the arrangement on a pallet.

A plastic container of this type consists of a pair of plastic face walls, attached to the opposite ends of a plastic side wall; each of these face walls consists of a pair of narrow side edges, which are held at a distance from each other by a pair of wide, parallel upper and lower side edges; the narrow side edges each have an upward projection at the opposite ends, which is interrupted by the exceptions of an adjacent container when the shelves are stacked vertically on top of each other; each of these upward projections furthermore delimits a narrow upper, open surface, with the surface of the ground parallel to the substantial nut of the brain.

A further design of the plastic container on which the present invention is based consists of a pair of plastic sidewalls with a plastic longitudinal wall attached between them. In addition, a lid is provided with a pair of longitudinally spaced sidewalls with a large number of outwardly extending protruding protrusions. The sidewalls are each connected by a pair of narrow sidewalls held apart by parallel wide upper and lower sidewalls, the wide upper edges having at least one of at least one of the upper sidewalls spaced apart, the first surfaces of which run parallel to the upper sidewalls.

In another embodiment of the present invention, the plastic container comprises a pair of plastic faces with a plastic longitudinal wall between them, consisting of a fixed part and a removable part. The fixed part of the sidewall comprises a side, the bottom and a lower lip part of the other side of the container. The removable part generally consists of a flat, rectangular plate fitted with fasteners to close the container along an edge to penetrate the lower lip part.

In accordance with another embodiment of the invention, the container also comprises a fixed part and a removable part of the sidewall. In this design, the fixed part has a first side, a bottom and a second side, the second side enclosing a rectangular opening in it. The removable part comprises a rectangular plate to close the second side when inserted into the container.

The preferred embodiment of the pallet consists of a certain number of extruded rails with a generally rectangular cross-section and a certain number of extruded cross-sections which also have a generally rectangular cross-section and are fixed between the rails. Each of the rails consists of an outer shell bounding an inner cavity, the cavity serving to reinforce the rails by incorporating an insert. In the inner cavity of the outer shell are channels which interfere with the upper circles formed at the insert.

Another design of the invention is a lightweight container with a number of stackable plastic containers and a plastic pallet. This system includes all containers with the pallet described above in the previous description. In this composition, the protrusions on the cross-sections of the pallet interfere with the exceptions of the adjacent containers when the containers are stacked on the pallet. By aligning the ground rail directly under the narrow sides of the front sides of the containers, a band can also be inserted into the containers beneath each floor rail, leading upwards over the outer surfaces of the containers stacked on the pallet and even over the containers, and it is possible to hold it in a trapezoidal nut directly above the top sides of the containers.

The plastic container and pallet system of the invention consists of stackable, stacked plastic containers which are locked in a similar way to the pallets on which they are stacked. Each container comprises a pair of sprayed front walls with protrusions along its upper edge and protrusions along its lower edge. Thus, when one container is sprayed on another, the protrusions of the bottom edge of the upper container are in contact with the protrusions of the bottom container. Similarly, the pallet is provided at certain intervals with mounting protrusions that are sprayed through the ground. All the protrusions in each container are placed on the front edge of the container. If a band is extended over the bottom of the container, the protrusions in each container are located on the front edge of the container.

The containers are made entirely of a special plastic material and are joined by vibration welding to form a unit. In one design, a side wall of the container can be removed to create an office shelf system with these containers on the pallet.

The pallet consists of two basic components, namely a number of ground rails with a number of cross sections attached to them at an angle of 90° and at a distance from each other.

Further features and advantages of the present invention are given in the subclaims and are apparent from the description below together with the drawings.

Fig. 1 shows a plastic container 11 comprising a pair of front walls 12 preferably made of structural foam, such as polypropylene foam, the front walls 12 usually form a frame of a pair of wide upper and lower side edges 13 and 14 running parallel, each connected to a pair of narrow side edges 15 and 16 running usually parallel.

A longitudinal wall 18 forms the connection to the front walls 12 and is made of plastic, such as high impact resistant polypropylene styrene, and is preferably produced by extrusion.

The longitudinal wall 18 comprises a number of reinforcement ribs extending along the length of the vessel 11 and parallel to the side-lips 21 only 19 beyond each edge of the wall 18 the extension of the lip 21 forms 90° inwards to the side of the vessel 11 curved ears 132 (Fig.4). An advantageous design of the extruded longitudinal wall 18 comprises a pair between two reinforcement ribs 19 and parallel inclinations 22 To form a U-shape with adjacent reinforcement ribs 23 the wall 18 is curved on one side by 90°. During bending the longitudinal wall 18 is bent under the influence of moderate heat and the moderate pressures to achieve a permanent deformation of the longitudinal wall 18 are also described above.

The front walls 12 and the longitudinal wall 18 can be assembled by several known methods including bonding and vibration welding. The preferred method is vibration welding. In both methods the front wall 12 intervenes at the end of the longitudinal wall 18, with the reinforcement ribs 23 at the narrow side edges 15 and 16 and the bottom side edge 14 of the front side 12. A detailed description of the construction of these parts is given in the description of Figures 5a and 5b.

The front walls 12 are fitted with a central opening 24 into which the insert 25 is inserted. The insert 25 is generally flat and rectangular and has markings indicating the origin of the packaged goods through the opening 24. The insert is also made of a plastic material such as high-strength styrene or polypropylene and is preferably produced by extrusion. The insert 25 is made by means of a suitable glue, cement or by vibration welding in the rectangular opening 26 on the inside of the front opening 12 . Vibration bleaching is the preferred method for fixing the insert 25 .

The lid 28 is fitted with a spring groove 29 which, as shown in Fig. 2, is arranged to loosen the handle or clamps of the upper side lip 21 of the longitudinal wall panels along the side lip of lid 28. The spring groove 29 according to this design encloses about 225° of the lip 21. This is done by including a spring groove 30 within the U-shaped groove 29 to meet the lower outer edge of the lip 21. This design also involves stabilizing the upper edge of each side of the lip 21 when the lid 28 is in contact. To facilitate the opening and removal of the lip 28A, the spring groove 29 is designed to be placed on the entire lip of the lid 21 (although the 3 and 5 pairs of grooves are parallel to each other, the 3 and 5 pairs of the deck 28A and 28A are also located on the sides of the deck 28A).

Figure 3a shows the lid 28 mounted and locked with the longitudinal wall 18 in this position, three of the 35 protrusions of the lid with the upper cones 32 are aligned. To remove the lid 28, the spring grooves 29 must be detached from the side lip 21 and the lid 28 moved in one direction until the 35 cover protrusions, as shown in Figure 3b, release the upper cones 32 of the front wall 12.In this position the lid 28 can be detached vertically from the tank 11. The closing of the tank 11 must be done in reverse order. Figures 5a and 5b show a lid line created by the upper and lower pins 32 and 34.12 spokes extending over a substantial part of the upper side edge 13 of each frontal wall, thus supporting each of the lid protrusions 35 and not only those supported by the upper protrusions 32.

As shown in Figures 1, 3a, 3b, 5a and 5b, the front walls 12 each have a pair of upward facing stack springs 38 at the ends opposite the upper edge 13. The stack springs 38 meet the stack gaps 39 at the ends opposite the lower wide edges 14 to prevent the vertically stacked containers 11 from moving to one another. Each stack sprung 38 is also equipped with a usable band 40 through which the stacked containers 11 can be held together with the pallet to form a palette composite. This feature is described in more detail after the introduction of the palette construction. The cover 28 includes a longitudinal band 27 to promote the expansion of the cover 27.

From Figures 5a and 5b, Figure 5a shows the inner surface of the front wall 12 with exceptions 26 and 134, lower studs 41 and fixing rails 44. Figure 5b shows the insert 25 mounted in the outlet 26, the lower edge of which touches the fixing rails 44 with its bottom edge. As described above, the insert 25 is preferably mounted by vibration welding. When mounted, it is seen that its upper edge contributes to the delimitation of the cover groove 36 between the upper and lower studs 32 and 34.

In the manufacture of the lid 28 and the longitudinal wall 18, the reinforcement ribs 19 are preferably integrated into the extruded plastic part and the extruded plate is extended laterally to the desired length and to form ears 132.

In the folded state, the plastic container 11 consists of a series of relatively flat parts which can be transported with little space required.

The plastic container 11 can be easily brought back into the production process by grinding the plastic parts and reusing the plastic material as an extruder load for extrusion of the longitudinal wall 18, the lid 28 and the insert 25. Extruding the lid 28, the longitudinal wall 18 and the insert 25 significantly reduces the manufacturing costs of the plastic container 11 compared to well-known paper, wood or plastic containers. Since the entire container 11 is made of both plastic, it can be used as a transport and display container, meeting all the FDE guidelines, as the material does not absorb any juice from the fruits or vegetables contained in the container and thus does not melt or prevent the formation of foodstuffs while in the container's container area.

Figure 6 shows another form of plastic container 11'. Essentially, the 11' container is the same as the 11' container as shown in Figure 1. The only exception is the longitudinal wall of two walls 18' and 18'. The 18' wall consists of the rear wall 46, the bottom 47' and the front lip 48. The front lip 48 only extends along the side edge of the bottom 47' and forms part of the front wall of the container 11'. The rest of the front wall forms the 18' wall.Along its upper edge, the 18' wall contains a spring groove 50 which, when closed above the lid 28', is in contact with lip 51 in a similar manner as shown in Figure 2. The rear edge of lid 28 is in contact with the upper edge of the rear wall 46 in the same way as shown in Figure 2 for container 11 in Figure 1. In addition, the 11' container can be closed by connecting the locking band 52 to the finger hole 31 by a metal or plastic lock or by a lock with a long lock.

The 11' tank differs from the 11' tank of Figure 1 also in that no through-holes are provided and the 25' insert has a break at one end of the tank where an identification card 53 can be placed.

Figures 7a and b, 8a and b and 9 show another design of the 11' tank. The 11' tank is essentially the same as the 11' tank of Figure 1, except that no ventilation is provided and an access hole 136 has been punched into the 18' wall.

Figures 10a, b and c show a pallet 100 to accommodate six containers in a plane of the type shown in Figures 1, 6 or 7a and b, three of which are stacked on top of each other and two behind each other.ground rails 102 consist of two parts, an outer rectangular section 116 with feet 118 and an inner, essentially rauten-shaped insert 114. The retraction of the feet 118 at the lower end of the outer rectangular section 116 forms the bandnut 112, which will be described in more detail later. Between the inner and outer rectangular section 116 there are channels 122 which fit into the approaches 120 of insert 114. Both insert 114 and outer part 116 are, for example, extruded from high-strength styrol or polypropylene and then extended to the desired length. The ground rails 102 are mounted by pushing the insert 114 into the outer part 116,The forks 120 are held by the channels 122 and this structure is connected by vibration welding, and then, to provide access for the forklifts, the forks 110 from the bottom of the ground rails 102 are cut to the side of the stacked containers 11 with the corresponding spacing between them. Each of the 104 cross sections also comprises 108 protrusions, spaced at a certain distance from each other, which are engaged with the stack exceptions 39 to accommodate the first 11 or 11' position containers stacked on the pallet 100.The material for the 104 cross-sections is preferably made of, for example, high-strength styrene or polypropylene and is extruded in a beehive pattern as shown in Fig. 10c. The final assembly of the pallet 100 is carried out by placing the 104 cross-sections on the 102 ground rails perpendicular to the 108 ground rails below the 108 cross-sections involved. The 100 pallet can then be welded by vibration welding or non-welding with the help of the access holes 106 which are connected by the 104 cross-sections into the 102 ground rails.In the case of non-welding, the welding apparatus creates a thermal compression connection between the lower plate of the quarter 104 and the upper plate of the ground rail 102.

The structure of pallet 100 made of high impact resistant styrene or polypropylene and the use of a beehive pattern inside the ground rail 102 and the cross section 104 achieve the low weight of the pallet with high stability, which, like container 11, can be installed on the field.

Figure 13 shows a pallet 100 with 30 containers 11 built on it. The pallet 100 is attached to pallet 100 by pallet belts 124 which extend under each ground rail 102 in band nuts 112, upwards over the front walls 12 of the container 11 through the band nuts 40 of the upper container 11, passing over the upper containers 11 and being brought back to the back of the pile. The belts may be made of solid non-stretchable plastic material and connected by known methods, e.g. thermal bonding or clamping.

Figure 14 shows a similar stacking system with a pallet 100 and 32 11' or 11' containers. This system is also connected by means of bands 124 in the same way as described in Figure 13. Figure 14 also shows removable compartments 128 within the 11' container to increase storage flexibility.

Finally, Fig. 15 shows mobile storage units 128 Each of these units comprises a pallet 100 with four wheels 126 and a certain number of containers 11' arranged on it.

The container pallet system underlying this description has many advantages. These are not only reflected in the stability of all the components of the system, but also in the fact that they carry only one third of the weight of conventional box and pallet systems. The wide temperature range they can withstand without damage is of particular interest. Styrene or polypropylene are materials that can withstand a wide temperature range, from freezing to temperatures substantially higher than those found in very hot climates.

The whole system, with its connecting springs and channels, prevents the containers from slipping and moving on the pallet during transport, since all the walls 12 of the 11, 11' and 11' containers have been shaped in precision shapes, giving the individual containers a higher degree of uniformity than the cardboard or wooden containers currently used. In addition, the stacking technology creates a boundary on all sides between the stacked containers 11. This provides for better ventilation during transport in and around the contents of the containers. The increased air movement reduces the risk of spoilage of the more sensitive food containers in the containers and thus contributes to increasing the profits of the individual container.
