Description

FIELD OF THE INVENTION The present invention relates to a container and / or transport device, namely, a box or crate, which is open above, for storing and transporting, for example, fruits, flowers, vegetables, bottles and the like.

In many countries around the world, including Hungary, a considerable amount of wooden boxes are currently used for the marketing of vegetables and fruits, which, however, are both aesthetically and hygienically objectionable, and wood is also quite expensive. Another problem is that although the racks are designed for ten years of operation, due to improper use a few times! they are ruined after use. Plastic crates to counteract these disadvantages have come on the market, but they are priced too high and, although more durable than crates, have been polluting the environment for decades after they are taken out of use. In any case, for reasons of hygiene, the means of transporting containers, which actually function as packaging, should not be reused. This explains why the reuse of packaging is already banned in some developed industrial countries.

For the reasons detailed above, wooden and plastic boxes are increasingly being replaced by cardboard packaging worldwide. They are made of wood or plastic auxiliary elements - hinges - which reinforce the corners of the folded cardboard for stacking (stacking) and forming the crates. The plastic hinge designs allow multiple, heavier-load compartments to be stacked on top of each other. In one such known embodiment, the low-pressure polyethylene hinge comprises a substantially triangular tubular member in cross-section, provided with a bottom-open, top-hole closure plate, and the outer sides (corresponding to the clamps) of the rectangular triangular column extend upwardly over the closure. This allows the upper compartment to be secured to the lower compartment, which however causes problems when stacking the crates. The four lower corners of the box, made of cardboard material, have to be routed at the same time between the upwardly extending walls of the hinges, and since the fit is very tight, the operation is rather cumbersome and requires skill. In addition, the straps often tear the bottom of the compartment intended to be inserted when attempting to insert, which not only increases loading time but also causes damage to the compartments prior to shipping, possibly resulting in a deterioration of the quality of the goods. A further disadvantage is that the wall thickness of the corner hinges cannot be increased indefinitely, since the greater the wall hinge thickness, the greater the cost, the greater the space requirements and the economical juxtaposition of the rows of crates. This problem is exacerbated by the fact that the height of the side walls of the cardboard drum at the corner connection is practically the same as the height of the hinge (corner pad), precisely because of the instability of the thin-walled hinge.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a storage and / or conveying device having a plastic hinge (corner toe) and corrugated bottoms and sidewalls whose plastic hinges, while thin, lightweight and inexpensive, are stable. They make it easy to connect to the compartment as quickly, easily and simply as possible, they rest on a large surface, and they fit well into the folded cardboard box corners.

The invention is based on the discovery that by folding this corrugated cardboard corner portion, the multilayer, hollow, closed section, thereby minimizing material inputs, can provide a sufficiently heavy-duty corner pillar member, including thin-walled and short cap-like corner hinges. by connecting more stable and heavy-duty compartments at a lower cost; and since the hinge member does not need to support (stiffen) the full length of the hinge member, the hinge members can be formed, as far as practicable, to arbitrary lengths independent of the hinge length. It is further recognized that the hinge does not need to have upwardly extending wall portions to its topsheet, and, in the absence of such overhanging portions, the topsheets may be used directly as abutment surfaces, and is secured.

Based on the above findings, the object of the present invention has been solved by the use of a container and / or conveying means (compartment) having a box section made of sheet material with bottom panels and side walls and corner columns formed by their own material; having hollow hinges, preferably made of plastic, that fit into and are removable from a corner post, the container and / or transport means having hollow hollow posts with closed sections having at least two layers of boundary walls on the outside, these boundary walls being formed by adjacent strips of sheets and / or sections of sheets; and the cap-shaped corner hinges have a mandrel extending outwardly from their lids, and apertures adapted to the mandrel are formed in the bottom plate of the box portion in the region of the corners. In a preferred embodiment, at least one of the two sidewalls meeting at each corner post has a projection folded to the side of the corner column facing the inside of the box portion and located within the hinge. Preferably, the mandrels have a truncated cone of upwardly decreasing diameter and the apertures in the bottom flap are circular. According to another feature of the invention, the cap of the hinge - for example, in plan view, includes a circular or triangular projection, and the mandrel

-2EN 201489 Β extends outward from this projection.

In a further embodiment of the storage and / or transporting device according to the invention, the corner posts are in the form of a rectangular triangle in cross-section, and the grips extend to this side walls and have at least two cardboard ends facing the inside of the box. and has an angle of 45 ° with the side walls, and the hollow cap-like hinges have the same or substantially the same cross-sectional shape as the corner posts.

Generally, the box portion is formed by folding of corrugated board or microwave board. It may also be advantageous if the profiled cut sheet member for forming the box portion has a line impression and / or perforation along the fold lines and if the hollow corner hinges are made of high pressure polyethylene.

The invention will now be described in more detail with reference to the accompanying drawings, which illustrate a preferred embodiment of the container and / or container. In the drawings.

Fig. 8 is a horizontal sectional view taken along line B-B in Fig. 1, in a larger scale, of a corner pillar forming part of a compartment of Fig. 2;

The storage and transport device shown above in Fig. 1 has a bottom panel 1 and a side wall 2,3,4 and 5 consisting of a corrugated board. The flat bottom plate 1 and the side walls 2, 3, 4 and 4 form the box part of the compartment. At the intersection of adjacent side walls 2,3,4 and 5, there are corner posts formed by bending (see later) of sheet material. Each of the four corner posts 6 is sealed and stiffened (stabilized) by a plastic hinge 7 (from the top). We will return to the detailed description of the cap-like hinges 7 later.

The bottom panels 2, 3, 4, and 5 and the corner posts 6 of the bottom 1 of the compartment 1 are shown in an expanded configuration and are formed by folding out a section of profiled cut-out, denoted by reference numeral 8. For example, the panel element 8 can be cut from a corrugated cardboard thickness of 5 mm into a die as shown in Figure 2. Continuous lines are contour lines (dashes), dashed lines are fold lines that are punched out or impressed, and where the dotted lines b are drawn, there is a complete cut between adjacent sheet metal sheet portions, i.e., adjacent sheet metal sections can be spaced apart. In the four corners of the plate member 8 there are one column forming plate portion 9 for the plate member portions 2 'and 3' corresponding to the side walls 2 and 3, which are divided into foldable plate strips 9a, 9b and 9c having different widths ex . 8, the tabs 10 of the panel members 4 'and 5' corresponding to the side walls 5 and 5 extend outwards from which the projections 10a extend inwardly; the latter two sections of disk elements can also be folded. In the region of the four corners of the bottom plate 1, there are 11 lugs each.

3-7. Figures 6 to 7 show a hollow body of injection molded plastic, preferably of high pressure polyethylene, with a wall thickness v of Figure 6, preferably 11.5 mm. The corner hinge 7 has a hole 12 at the bottom, a triangular top wall 13 with rounded corners and a closed profile profile lid 14 with a circular projection 16 on the top. From the latter, the spikes 15 extend. Below, the heel strap 7 has an outwardly extending short sole 17 which runs round. The whole 7 hinges are molded in a single member. In the embodiment of Fig. 7, the support surface is provided with a reference numeral 18.

The container and / or transport device according to the invention is designed as follows:

In the first step, the plate parts 8 'and 3' of the plate member 8 shown in FIG. 2 are folded at an angle of 90 °. The strips 9a, 9b and 9c of the column forming plate portions 9 are then folded in all four places - inwardly, i.e., inside the plate portion portions 2 'and 3'. 9a and 9b of the flat strip is flat strip is carried at 90 ° ^e 130, respectively, 9c flat strip 150 degrees. The plate members 4 'and 5' are then folded 90 ° and their respective tabs 10a are folded laterally outwards by 135 ° to the corner column portion formed by the former. These tabs 10a secure the side walls 2 and 5 (Fig. 1) against falling out. The sidewall plate portions adjacent to the panel strip 9c are designated by reference numeral 19. As a result of this folding operation, the cross-section of the corner posts 6 is shown in Figure 8; it is clear that the two most exterior walls of the triangular cross-sectional corner, which are contiguous with the side walls, are double and the longest strip 9b is formed by the cross-section of the corner columns 6 shown in Figure 8; it can be seen that the two most exterior walls of the triangular cross-section, which are adjacent to the side walls, are double, and the longest strip 9b forms the inner wall of the corner column 6 facing the inside of the compartment = 45 °. angle. It should be noted that, for the sake of clarity, the panel portions forming the corner column 6 are shown not in alignment with each other, but slightly removed from one another in Figure 8. Columns of this construction have increased load capacity, properly stiffen the entire compartment and ensure that the compartments (crates) do not collapse when stacked.

In the next step, the sections forming the corner columns 6 having a right-angled triangular cross-section are clamped together with one hand and guided from above with the other hand. 6 to 8, so that the lid 14 with its inner surface rests on the top of the corner pillar 6. The same operations are carried out on the other three corners, thus completing the storage and / or transport means, i.e. compartment, in Figure 1, in which the product to be stored and / or transported can be placed.

Stacking of the compartments can simply be accomplished by stacking the compartments by simply making sure that the openings 11 in the bottom plate 1 of the upper compartment fit into the mandrels 15 of the respective lower compartment (Figures 1 and 3-6). Thus, the overlapping compartments cannot slide sideways relative to one another.

As can be seen in Figure 1, the side walls 2,3,4 and 5 are elevated in the region of the corners so that there is a ventilation gap between the compartments when they are superposed. On the other hand, due to their high rigidity, the corner columns 7 may be relatively long, even with compartments having different longitudinal columns within each stack, so that the compartments can store and / or transport goods of different purposes and / or dimensions.

Figure 7 illustrates the corner hinge of Figure 3-6. 2 to 4 are essentially different in that the raised surface 18 is maximum.

Advantageous effects of the invention may be summarized as follows:

the weight and wall thickness of the container and / or conveyor according to the invention is minimal, but substantially more stable than similar compartments currently known. In combination with the high stiffness corner posts 6, relatively short cap-like corner hinges 7 can be used, the cover of which distributes the pressure exerted by the respective upper compartment, while the pins 15 extending from the covers 14 and fitting into the openings 11 of the between stacked compartments. The wall of the box sections does not need to support the heel strap 7 at its full height, so that any size air gap can be used within practical limits so that not only fruits and similar products but smaller live plants or even animals can be transported in the container. There is no need for wall portions that extend upward over the lid and support the lower corners of the upper compartment, which not only saves plastic, but eliminates the need for cumbersome customization when stacking the compartments and the risk of damage to the cardboard material. For example, the box section may be made of 5 mm corrugated board or, if the compartment is used for light goods, microwave board. Otherwise, the compartment may be made as desired by the customer, and the size of the bottom plate 1 and / or the height of the side walls may be varied. Choosing the latter size ensures that even higher items (such as flowers, seedlings, etc.) can be transported in piles when the crates are stacked.

The bottom and side walls of the crate can be provided with cut-outs on demand so that the necessary ventilation of the crate can be ensured in all cases. Thus, in addition to the gap which appears in any case between the reclining compartments, additional air passages are created. Otherwise, the cap-like plastic hinges 7 also protect the rocks 6a10 from wetting.

The compartment label can be retrofitted with the printing technology after the panel member 8 has been cut, since the panel member 8 is in an expanded state until use. It is also very convenient to transport, as one pallet can be transported with about 1000 pieces of expanded sheet metal together with the corresponding plastic hinges.

The crate is aesthetically pleasing, allowing goods to be transported from the manufacturer or producer to the end user, such as the buyer, without the need for transhipment. The compartment cost is low. If needed, for example for fragile or delicate goods, the compartment can be provided with a vacuum-suction insert that protects the cardboard from soaking. The carton material in the box is cheap, non-polluting and can be, for example, incinerated after use, and the plastic hinges can be reused and re-purchased by the manufacturer.

The invention is, of course, not limited to the embodiment detailed above, but may be practiced in many ways within the scope of the claims. For example, the folded box part can be made not only of cardboard, but also of paper, other material or other rigid sheet that can be flexibly edged. Corner columns may have a cross-sectional shape other than the triangle. The heel strap does not have to be made of plastic, for example, metal or other material.
